Projects

Due to the cranial suture ossification in conjunction with age, the degree of fusion between the neighboring skull plates has been used as a predictor for estimating age, based on skeletonized human remains. So far, this involved the use of subjective ranking techniques, which rely entirely on the human opinion for assessing the degree of fusion. Such methods have shown to require a lot of human resources and not produce sufficiently accurate results in comparison with other age estimation methods. This project manages to entirely automate the process of age estimation based on cranial suture analysis and based on the

A Study of Transition Metal Substituted Prussian Blue Analogues

The sodium ion battery has limited usage of cathode materials due to its large ionic radii. Prussian Blue Analogues (PBA) have appropriate structure to storage sodium ion but low specific capacity and structural stability cause hardship for commercialization. To solve this problem, It have been preferred to improve the performance by substituting R-site metal. In this study, however, we changed the P-site ion to optimize PBA. we synthesized PBA with 5 different transition metals and the Fe[Co3(CN)6] exhibits a specific capacity of 625mAh/g at 0.1C. Furthermore, the result suggests the tendency between Jahn-Teller effect and reversibiltiy of cells. We believed

Acoustic levitation. Building and analyzing two different acoustic levitators based on piezoelectric transducers, and exploring its current and possible future applications using simple physical and chemical experiments.

The paper explores the notions of Acoustic Levitation using acoustic tractor beams with both single and double arrays. These devices are able to generate different types of acoustic traps allowing the levitation of objects of low density and up to the size of half a wavelength. For this purpose piezoelectric transducers have been used. Based on Dr. Asier Marzo’s investigations, the main aim of this research paper is to prove the effectiveness of this method and to explore its potential applications in areas such as medicine, biology and technology. To test the applications of this method, several measurements, experiments and

Advanced ARAGO, a „gravitational wave“ detector

LIGO and Virgo American-European scientific collaboration made first detection of gravitational waves produced by a binary black holes merger (BBH)On the same principle, we simulate a gravitational wave detector with a completely innovative technique. This way we create a deformation of the space which corresponds to an hypothetical BBH merger. We detect and analyze it thanks to techniques which are similar to those used by scientists in order to determine the parameters of the event : mass of merging objects and distance to the Earth.On the footsteps of the scientist Arago, a pedagogue and a great popularizer, we propose an

Affordable 3D-printed Equipment for Innovative Robotics Education

This project deals with the development of 3D-printed models, electronics and software for innovative education in robotics, sufficiently cheap to allow the schools (technical or vocational, as well as re-qualification courses or hobby clubs) to afford them for all their students in the class. Each and every student might make/repair/improve his/her own robots from a scratch and naturally “learn-by-making” multiple subjects from CAD modeling and 3D printing to electronics assembly to coding on multiple platforms. The models developed so far include the universal control system for a wide range of 3D-printed robotic manipulators, and a robotic model of a human

Algorithms for independent operations of a robot in a lava tube on the Moon

For decades, mankind has been dreaming of colonizing the Moon and Mars. This idea raises various scientific, technological and economic challenges. In 2009, lunar probe discovered moon cave, which may be optimal base for a habitable base protected from radiation. First exploration stages may include robotic mission. In this work authors designed algorithms that implement automatic robot rescue if communication was lost. A new method of measuring the efficiency of the rescue algorithm was developed — a complex parameter that includes the time to search for a communication site and the amount of energy consumed. The algorithms were tested and

An Intelligent Directional Following Device Based on Ultrasonic Positioning and Robust PI Controller

The project designs an intelligent directional following device based on ultrasonic positioning and strong robust PI controller. It locates and follows directly under the beacon’s guidance, which brings fast calculation, high positioning accuracy and sensitivity, low energy consumption, and easy control. New algorithm based on four receiving sensors also makes positioning more accurate. Using robust PI controller let it move much steadier and more adaptable to complex environments, with strong anti-interference ability. Its warning system ensures safety and no touching obstacles. Moreover, 3 highly reliable Omni-Wheels, 120° apart, make it move instantaneously in any direction. The device can be widely

An intelligent system to monitor air pollution and prevent its health effects

Knowing in advance how air quality will change over time can help prevent the harmful effects of air pollution on health. Therefore, an entirely self-developed forecasting system consisting of a strong statistical model evaluated using different regression methods was built for this purpose. Data is provided by a wirelessly interconnected, self-sufficient measuring station built using a nanocomputer and sensors. The intelligent system I designed learns what air quality disturbs a specific user since people from different age groups with different diseases don't endure the same pollution level. Thus, the platform tries to implicitly diagnose the capacity of a certain user

An Interpretation of Life Through Vibration Motors

Independent travel and the ability to interact with the world are two of the greatest challenges facing blind/ visually impaired (BVI) persons. Traditional tools, such as the white cane and guide dog, are limited and do not provide users with the information they need to navigate effectively and gracefully. I worked to develop an advanced electronic travel aid that uses ultrasonic sensors and LIDAR to provide BVI users with enhanced spatial perception through vibro-tactile feedback. The device was developed to equip users with a tool to overcome their social and navigational challenges and give users the confidence and comfort to

An investigation of genomic alterations for the survival of high-grade astrocytic tumours

Glioblastoma is a grade IV astrocytic tumour and is anaggressive brain tumours mostly affecting adults. Survival rates are poor and in an attempt to further understand the cancer and develop treatment that can better fight the tumour and further increase survival rates, experts aim to understand Glioblastoma biology and different genetic alterations that may have an effect on survival. This essay aims to explore two genetic alterations, MGMT gene methylation and IDH gene mutation and their effect on the overall survival rate of Glioblastoma when given the Stupp protocol as treatment.

Analysis of glyphosate residues in honey

This study is about the analysis of glyphosate residues in honey. We tested 8 different honey samples with the ELISA technique. From 8 samples, 12.5% of the honey samples were positive, 12.5% were not conclusive and 75% were clearly negative, since the average concentration was under the limit of detection. The one positive sample was near the MRL (Maximal Residue Level) in Europe. The positive sample is known to come from an organic beekeeper. The question arises how and why the honey contains glyphosate residues.

Artificial Intelligence System Object and Place Recognizer for Blind People and Development of Data Set

In many areas, such as finance, health and safety, and in the process of facilitating the lives of persons with disabilities, artificial intelligence systems operate. Applications developed using artificial intelligence technologies are able to identify visually impaired objects, while location recognition practices are inadequate. With a mobile application that works on deep learning as we develop for our project and does not require an Internet connection, visually impaired individuals can identify places near the external environment. Individuals with no visual impairment can also be part of the solution by taking pictures of the surrounding sites, thereby contributing to the growth

ASA treatment for oil spills

In the event of a maritime oil spill, good advice is hard to come by. While traditional binding agents can absorb crude oil on the surface, they are expensive and have a limited effect. Paul Kunisch and Thomas Derra are on the hunt for better sorbents. They impregnated pulp with ASA, an industrial sizing agent that resembles well-known oil binding agents in its structure. Its traditional use is to make paper water-repellent. The young researchers' experiments were successful: Their ASA-impregnated sawdust, cellulose fibre granules and non-woven fabrics are cost-efficient and even have a better sorption capacity than commercially available agents.

Automation and Remote Control of Astronomical Telescopes for a Global Asteroid Survey

Our goal is to solve the problem of important astronomical observations not getting enough telescope time. We think this problem can only be solved by involving amateur astronomers. To make this easier we have designed a system to automate the data collection and some of the processing of astronomical data. With the hardware and software designed to operate together, we can collect quality datasets, therefore they can be used for scientific research. We are mainly concentrating on Minor planet research, more specifically photometry and orbit calculations of Near Earth Objects. The product also functions as an automation controller for artistic

Blockchain Decrypted

In my project Blockchain Decrypted I developed a method how the complex fundamentals of Blockchain can be explained in an intelligible way. The functionality and mathematical backgrounds of the future-oriented Blockchain are presented in an understandable way. Furthermore, an exciting application of the Blockchain, called Smart Contract, is described. An own Smart Contract, which implements a TicTacToe game, has been developed and an own crypto currency has been created and integrated. Thus the most exciting aspects of the Blockchain are demonstrated, the possibilities of the technology are clearly recognizable. Thanks to a webpage-interface, the game is easy to use. My

BoneSound

Bone conduction headphones offers the possibility to listen music to deaf people. The bone conduction is a sound propagation method that passes sound not through the air but through bones onto the ears. Hearing people can also listen music, additional the environment noises. We choose to propose a system based on simple components. The aim was to put forward assembly plan accessible to everyone, for a self- manufacture, much less expensive (approximately 50€) and custom-made. All of our work and researches are gathered on a website. We coded a software to optimize the listening of music with the bone conduction.

Brain Cells Phenotyping Via Unsupervised Machine Learning With Autoencoder and Clustering

We work with an image database of brain cells and aim to develop an unsupervised neural network, consisting of autoencoder and clustering layers, to classify whether the input image contains a cell or not. The cell types which we have tested the algorithm on, are microglia and inhibitory neurons. We feed image patches to an autoencoder with a small latent space and perform clustering on the compressed data representation from the latent space. We expect that the encodings of "positive" and "negative" samples would differ from each other and thus form clusters in space. The achieved results show a good

Calcium phosphate bone cements: from α–tricalcium phosphate synthesis to production of bone cement

The aim of the work was to synthesize bone cement based on calcium phosphate, which is the main inorganic component of human bones. The bone cement based on calcium phosphate nowadays can be used to treat even fractured vertebra, thus improving the life quality of those peoples who suffer from osteoporotic bone fractures. In my project, I review the different methods of bone cement synthesis and compare the mechanical properties of cement made from calcium phosphate which is synthesized in high temperature and it's mix with calcium phosphate which is synthesized in low temperature.

Catching the Bad Guys: Capturing Oligomers of the Amyloid-beta Peptides

Alzheimer’s disease, Parkinson’s disease and type 2 diabetes have been linked to the formation of amyloids, large aggregates formed by missfolded proteins. Studies show that a so called oligomer forms as an intermediate in the reaction when smaller peptides form amyloids and it has been hypothesised that these oligomers are the main causes for the diseases. However, research on the oligomers is hindered by difficulties in capturing them. The goal with our study was to tackle this problem. Using a method referred to as Trap-and-Seed, we were able to consistently produce and capture relatively large quantities of oligomers in less

Design Of A Self-Learning Prosthetic Hand Using Wireless Data Transmission and Flex Sensor

The project aims developing a prosthetic hand that can transfer data received from the flex sensor glove wirelessly and memorizing the desired movement. Prosthesis hand designs were examined and two of them were printed by 3D printer. In order to detect the desired movement of the hand, flex sensor glove was made. Flex sensor glove uses XBee for wireless data transmission.Movement of the prosthetic’s fingers is provided by servos. When the motors stretch the line the fingers close and when they release they open. A keypad is added for reducing the use of gloves. Once the desired movement has been

Development and application of analytical method for determining iodine anion in highly mineralized water matrices

It is not spoken so much about Iodine in the world. But lode, in the nature represented like iodine is as important for our body as every single needed element. In my work, I was determined iodine anion in mineral water. There are not some exact value for available quantity in mineral water and many of producers does not mentioned quantity of iodine, which is contained in each mineral water.There are not any qualified method to determine iodine in water. In old database I found out some old spectrophotometry method and I started with modifying this method according necessary parameters.After

Diffrec PRO

The team developed a so-called differential pulley block for alpine lightweight synthetic fibre ropes, which will be easy and simple to handle. They calculated and compared different concepts and found a serrated differential roller with three differently sized grooves. The axle of the pulley is suspended from two side plates, which also provide a suspension point for a carabiner. A mechanism presses the rope into the serrations so that it doesn't just let go. They found a very smart solution for the improvement of pulley blocks for alpine applications.

Distant Monitoring

Our project is innovative, it does not resemble the applications provided today as the tele-medicine develops. This multi-functional device unites the blood pressure, electrocardiogram, pulse, breath frequency and temperature measurement, and lets doctors and patients have a consultation distantly and rapidly, using the internet. The patient owns this device, connects to the doctor, who gives the patient instructions on how to use all the tools, controls the device and starts it up. He sees everything on his tab(or any gadget) at that very moment he starts measuring, and most importantly he observes everything graphically, virtually and numerically, synchronized with the

Distributed creation of Machine learning agents for Blockchain analysis

Creating efficient deep neural networks involves repetitive manual optimization of the topology and the hyperparameters. This human intervention significantly inhibits the process.Neural Architecture Search (NAS) algorithms can effectively automate this work and achieve results that surpass the best human-designed models.This research proposes a novel blockchain network protocol that incentivises independent computing nodes to run NAS algorithms and compete in finding better neural network models for a particular task. If implemented, such network can be an autonomous and self-improving source of machine learning models, significantly lowering the cost and access to accurate Machine Learning solutions.

E250 – The Silent Killer

E250 or sodium nitrite is a synthetic additive used in meat products. Its consumation leads to many disorders including the cancer of large intestine. Our goal was to find out the concetration of E250 in meat products and its effect on blood cells. We examined 20 samples. Average concentration of nitrites was 1.6 mg/kg (in drinking water it is approx. 0.3 mg/l). We applied this amount into the five samples of human blood and using blood cells´ analyser we observed the rapid decrease of leukocytes, erythrocytes and platelets as well as the changes in hemoglobin and hematocryt. We proved that

Materials

EcoMe is a reusable, ecological and affordable menstrual protection product aimed for developing regions. The qualities of the menstrual pad are based on an interdisciplinary research. A user survey was conducted in three Asian regions: Mongolia, Azerbaijan and China. From the results, limitations and preferences towards an ideal menstrual product were obtained and further used in the design of the product. Different materials were explored and the decision on using sea sponge as an absorbing material is based on the most important qualities of the material: absorbance, drying time and cleansing. In addition, an informative mobile application was created. The

Electronic hardware and software system for posture correction and platypodia diagnosis among adolescence and middle school students

The accomplished scientific and technical project is aimed at preserving children’s health. School age is a period of ontogenesis, when various types of impaired posture are clearly manifested. According to statistics, 10-40% of school-age children show signs posture faults. The project solves a complex of interdisciplinary applied problems of posture correction and flatfoot diagnosis, taking into account the interdependence of posture disorders and foot deformities. The project is done at the intersection of human physiology, rehabilitation science, and electronic engineering. A hardware-software complex including a combined posture corrector for teenagers and a stop-meter detecting signs of flatfoot is developed. Several

Elongated hexapawn

Elongated hexapawn is a board game based on chess, devised by T. R. Dawson. It gained recognision when Martin Gardner used it for the first popular description of machine learning. Still, the game remained unsolved: perfect gameplay was not known. The paper Elongated hexapawn closes this gap, using many combinatorial transformations and the basis of game theory, Sprague-Grundy theorem. Apart from describing the best moves in every position and giving some possibility of using similar methods for solving other board games, there is also a potential application in improving the quality of machine learning. The artificial intelligence can play against

Environmental magnetism on the Black Sea Coast, in situ versus laboratory measurements

The objective of our project is to monitor the pollution of the seaside environment using magnetism as a working method. The following types of measurements were made:1. In situ: magnetic susceptibility measurements2. In laboratory: magnetic susceptibility measurements, magnetic hysteresis, curie temperature.We have also monitored this year: beaches in our town and trees in the areas adjacent to the main seaside highway. The main conclusion is that measurements of magnetic susceptibility can be used in the study of environmental qualities. The susceptibility level can be used as an indicator of environmental pollution. Comparing the measurements in situ in the laboratory showed

Evaporative desalination with industrial waste heat

One of mankind’s biggest threats is the ever growing water shortage. One way to solve this is to clean seawater. Today more than 300 million people get their water from desalination plants around the world. Conventional desalination is however both expensive and energy demanding. Therefor i have developed a new way to desalinate seawater by utilizing water’s evaporative properties together with industrial waste heat, reducing the cost of cleaning 1000 liters of water to just 0.06€. Industries use 20% of freshwater around the globe and 60% in wealthy countries so self sustaining factories through my invention would be a huge

Extension of the application range and parameters of the Airy pendulum for obtaining Lissajous curves

The Airy pendulum is a simple mechanical device for demonstrating the addition of two mutually perpendicular oscillations of the load which trajectory has the form of Lissajous curve. During experiments it was noticed that some Lissajous curves did not match with ones calculated according to the classical theory of Airy pendulum oscillations. In this project theoretical model of Airy pendulum load composite oscillations in specific conditions is developed and is used for the Lissajous curves form explanation. The proposed theoretical model is confirmed by the results of experiments in this project.

Fabrication of binary amplitude holograms using a film camera

Fabrication of holograms is generally complicated and expensive. Therefore, it was studied, how to create high-quality computer-generated holograms using only affordable and widespread equipment. To make binary amplitude holograms with customized diffraction patterns, a computer program was written and photographic reduction with a film camera was used. The optimal parameters of the fabricated holograms as well as differences between using three different film types were determined. It was found that all film types are suitable for fabrication and in addition to laser light, the diffraction patterns are clearly visible when a mobile phone flashlight is viewed through the holograms. Such

From Waste to Bioplastic

We produced bioplastic sustainably from natural materials that are not very useful nowadays, namely coffee dregs, dried leaves, annual plants, acorns, lupine seed peels and acacia seeds and leaves. Promoting a circular economy, from rice grains discarded by large industries, we produced a bioplastic that can be used in the manufacture of packaging and biofilters capable to remove heavy metals in aqueous solution. We also produced bioplastic from surplus cooked rice in order to combat food waste. We used commercial glycerin, but also glycerin in excess of biodiesel production from used cooking oil. The bioplastics obtained are flexible and resistant.

Gene regulation during development: The roles of the genes xbp1, creb3l1 and creb3l2 in axial mesoderm differentiation

By dividing and differentiating, a single cell can develop into a complex multicellular organism such as a human being. Transcription factors are proteins that play an important role in the development by regulating the activity of genes. In this project, three transcription factors and their roles in the development of a specific tissue in zebrafish were investigated. By using new methods, I revealed previously unknown regulatory interactions, which improved our understanding of the roles of the three transcription factors. The findings could lay the foundation for the development of new medical diagnostics and therapies, since all three transcription factors have

High Altitude Micro Air Vehicle

Stratospheric missions allow us to forecast the weather and broaden our horizons in many fields, ex. astrobiology. Whenever we send a balloon into the stratosphere it gets blown off course which makes it hard to find and retrieve the experiment. We designed a drone that could, after being lofted into the stratosphere suspended from a balloon, return with a payload to the location of launch. We produced a prototype that we put through a series of tests, during which it became the worlds’ first micro class drone to return from the lower layers of the stratosphere carrying a scientific payload.

High particulate matter filtration efficiency Nano-fibrous membrane

Particulate pollution has led to catastrophic health and environmental consequences. As a result, new approaches have been done to increase the efficiency of the air filtration equipment. Here a novel nanofibrous air filter made via electrospinning process is demonstrated, which has attractive attributes of high filtering efficiency and low resistance to air flow. The filter could be manufactured with a transparency of 90 % and an efficiency of > 85% under intense smoke exposure. Consequently, the filter could be applied as a muzzle, an alternative for catalytic converters of car exhausts or fabric filters used in the treatment of factories

Hoverboard – a Magnetically Levitated Vehicle

In the science-fiction classic "Back to the Future II," actor Michael J. Fox whizzes through the streets on a skateboard that has no wheels - it floats over the ground like a hovercraft. This is precisely the technology that Felix Sewing and Alex Korocencev have been puzzling over. Their vehicle is based on four rotating discs that can induce a powerful, repulsive magnetic field on a metal plate located beneath it. The load capacity of the board is impressive indeed: the prototype can lift a considerable weight. In addition, the rotor discs can be tilted individually, allowing the board to

How to clean up the oceans?

When our teachers asked us to find out a project, we immediately thought about environmental problems which is a great challenge. Further we thought about the pollution of our oceans and how could we struggle against it. We know that there are a lot of polluting substances in the water and that those have a devastating impact on the marine wildlife. We’re thinking here about plastics bottles, bags or oil and many more. We decided to set our research on oil. So, we created a boat filled with active carbon. This one can adsorb the oil floating on the surface

Improving recovery time of patients with an Ilizarov external fixator around the ankle

The Ilizarov apparatus is used in orthopedic surgery to treat complex fractures by using an external ring around the ankle to fixate the limb in order to lengthen and heal the bone. When the fracture occurs in the ankle area the bottom ring is often located under the foot and prevents the patient from bearing weight on their broken limb. Weight bearing is essential to the recovery process.Our project provides a method for patients with an Ilizarov apparatus fixated at the ankle area to bear weight on their leg, improving the recovery time for such fractures.

Individualised footwear to correct children’s feet

Companies producing orthopaedic footwear use a static model for children’s shoe production. As a consequence, children do not wear orthopaedic shoes regularly because they are not comfortable. I have studied the possibility of correcting children’s flexible feet by analyzing the dynamics of load forces between toes and heels both when walking barefoot, and when various combinations of shoes and insoles are worn. As a result, I have developed a method to design comfortable footwear which is effective in correcting asymptomatic flexible children’s feet. I suggest using the dynamical method to improve the quality of orthopaedic shoes, and working together with

Inhibition of glutamate excitotoxicity in glaucoma by liposomes

This project proposes a novel treatment of glutamate excitotoxicity which affects all neurodegenerative diseases. In case of glaucoma, it causes vision loss of 64.3 million people worldwide. This work suggests application of liposomes as detoxifying agents capable of glutamate absorption via incorporated membrane EAAT2 transporters. It is supposed that absorption of excessive glutamate by liposomes should prevent receptor over-stimulation and protect the neuron cells. Liposomes suitable for such purpose were synthetized. Their characteristics were assessed by fluorescent microscopy and Raman spectroscopy with Raman imaging.

Introduction of a Novel Diodicity Evaluation Criteria and 1-D Approximate Model for Multistaged NMP (No-Moving-Parts) Check Valves and Methods for Valve Stage Optimization

A new diodicity evaluation criteria, Volumetric Diodicity (Dv), is introduced to analyze the diodicity of NMP (No-Moving-Parts) valves. Recent studies about the valve system are based on the pressure diodicity, defined as the ratio between the pressure drop in forward and reverse flow. However, existing evaluation criteria do not show discrete relationships with actual data. In this paper, an inelastic collision-based analytic turbulent model was designed to approximate the tendency of diodicity by stage number and was verified both experimentally and numerically with CFD (Computational Fluid Dynamics). The new diodicity criterion can be applied in numerous fields that require NMP

Investigating detection of floating plastic litter from Space

The idea was to create a “plastic target”, in order to investigate if plastic floating in the sea can be detected, depending on its Spectral Signature using satellite or drone. Firstly, we took in situ and laboratory measurements on plastic to create a representative database and discovered its special characteristics which were used as guidelines to spot it. After creating and taking measurements on the target we analyzed the data and created a Prototype Code. Finally, by testing the Prototype Code of plastic bottle, we confirmed that accumulated plastic rubbish can be successfully detected using satellite or drone. Thus, a

Investigating the Effect of Activated Charcoal on the Absorption of Medicines

Activated charcoal is often found in toothpaste to whiten teeth, in face masks to clear the skin and as a food supplement to remove ‘toxins’ from the gut. My project investigated the effects of activated charcoal on the absorption of medicines by measuring the conductivity and Total Dissolved Solids of solutions. I created solutions of medicines with deionized water; either with or without activated charcoal, filtered the solutions and measured the change in conductivity in order to ascertain if the drugs were still available to be absorbed. My results showed that conductivity and TDS are both reduced after the addition

Investigating the Role of the Novel ESCRT-III Recruiter CCDC11 in HIV Budding: Identifying a Potential Target for Antiviral Therapy

Infection with human immunodeficiency virus (HIV) causes acquired immunodeficiency syndrome (AIDS). Nearly 37 million people are infected with HIV worldwide, and 1 million people die of AIDS-related illnesses each year. As of today, there is no cure, and current medications are frequently associated with severe side effects. To discover a novel target for anti-HIV therapies, we studied the role of coiled-coil domain-containing 11 (CCDC11) in HIV formation. Our data suggest that CCDC11 is required for efficient release of HIV particles from the cell surface potentially through recruitment of the membrane scission machinery called ESCRT-III. Given the fact that CCDC11 is

Investigation of the Prince Rupert’s drop properties

Prince Rupert’s drops (PRDs) are very interesting from both scientific and commercial points of view. The main achievements of my theoretical and experimental research are studying the way of PRDs obtainment, defining how much shape and optic-mechanical properties of a drop can vary and achieving very accurate data of how much pressure can PRDs stand. The most important commercial aspects are creation of PRD-based drilling bits, which are muchcheaperthan nowadays’ diamond onesbut still as good as them, composite body armor prototypes and experiments with PRD + concrete composites.

Life Shirt

Nowadays, heart attacks are one of the leading causes of death. My solution is Life Shirt; a shirt that monitors one's vital parameters in order to predict the risk of having a heart attack. The shirt uses a range of custom-made sensors and is able to monitor in real time. It is suited for intense activities like sport and people that are aged above 50. The shirt contains dehydration, temperature and heartrate sensors. With all the information that these sensors provide, it is able to predict a heart attack. As it will detect low hydration and high temperature accompanied with

Maat in old Kingdom Egypt

Maat is a word, principle and goddess in Ancient Egyptian thought and religion. Maat was thought of as the embodiment of order, both in the cosmic sense, and in the social sense. On the one hand, Maat was perceived as justice and social hierarchy, and on the other – as truth and “physical” order (such as gravity, tide and sunsets). In this paper, I examined the textual references of Maat in the Old Kingdom, focusing on the second half of the fifth dynasty (2445-2345 BCE). This period is thought to be a time of great changes, both political and religious.

Microorganisms and Proper Nutrients as Natural Protection from Frost

In years 2016, 2017 spring frost caused a major plant damage over the large majority of Slovenian teritory which had a strong impact on national economy.With our reserch, we wanted to prove correlation betwen microorganism activity and plants ability to store osmotically active nutrients which could serve as a protection from spring frost. These nutrients form bound water which has a much lower freezing point.In our reaserch we used plants with longer lifespan, for they are most affected by spring frosts and the damage is of larger consequence. Becuse of that we chose vines.We tested the nutrient content of soil,

Microplastic on our doorstep

The team analyzed the degradation of microplastic in their home river. They found out, that even after 30 days of treatment through contact with the microorganisms in the sewage sludge, the small plastic particles do not degrade completely. Even plastic polylactate, which is labelled as biodegradable, is particularly resistant to sewage sludge. Polyethylene terephthalate (PET for short) is the only material in which the sewage treatment promotes significant chain degradation. The outstanding team adressed a serious problem and worked on a scientifically advanced level.

Monitoring the tooth brushing quality for teenagers with smart watch

The oral problems of young children are particularly serious because they are at a critical moment in developing good oral hygiene habits. How to help them maintain oral cleaning through sensors and artificial intelligence technology has become a research point of intelligent Internet of Things. We present an easy accessible monitoring system for evaluating the tooth brushing with smart devices. The system captures the users' brushing behaviors (e.g., the motion of hands and the acoustic signals during tooth brushing) through the two build-in sensors. Then the collected data is transmitted to the smartphones and evaluated through a designed machine learning-based

MOOSIC: a mean for productivity optimisation

This project is an investigation of the phenomenon of MOOSIC – the proportionality between music and the productivity of the dairy cows. Accordingly, I have surveyed, how the compositional parameters of the accompaniment (including both consonance versus dissonance, the level of activity and the tempo) affect the oxytocin release, that is essential to the milking production. Through verifying this on 433 dairy cows, I found a productivity optimisation of 2.4%, by which Denmark could reduce its dairy herd with 15,000 cows. Thereby, this MOOSIC will not only be a mean for productivity optimisation, but as well for minimising the climate

Moth.NET

Pests can ruin every healthy tree crop within 10-15 days. If pest-control is executed, 50-75% loss may occur. Observation, forecast, prevention. These three words can describe my project.How is it possible to keep track about all of the pests inside the fruit? – I developed a system which can monitor the insect traps. In this trap there is a high-quality camera and a monitoring microcontroller. The automated pheromone trap what I developed would be effective for farmers for economical, environmental protection and environmental reasons. It helps the owner to buy the right amount of pheromone, glue and spray, so you

Motorised Platform for Inverted Microscopes Olympus IX 50 and IX 70

Moving samples at high magnification manually is not easy and purchasing motorized platforms often is not affordable.This brings about the idea of building a platform from scratch, through Open Source tools and under Creative Commons license, making the project a starting point for further developments as well as an incentive for young people who may want to experiment.The minimum movement along the axes equals ~27nm. The platform allows to automatically go back to a previously saved position, with a tolerance of ~30µm. A display shows the current position and so it is possible to take note of all interesting positions

Music Splash

Music Splash is an app designed to help students develop their musical ability and musicality. The app uses machine learning to account for and identify the players own elements of musicality and help to enhance them. The app gets input which is initially stored as a .wav file. This .wav file is then put through a process, parsed by the computer, to convert it into a file format that can be used. Once the file has been converted, it is compared to a base file that has been pre-recorded by a teacher. This analysis, due to the complexity of music,

Mycotoxins: a major issue

Mycotoxins are small compounds, which consist of by-products of fungal metabolism, and that can be found in various food consumables of our diet. When ingested, these chemical substances may cause various diseases and, in extreme cases, the death of contaminated individuals. Therefore, it seems to be essential to develop an easy and effective method that enables the detection of some of these toxins in our body. In order to tackle this issue, this project’s main purpose was to create a non-invasive, easy-to-use and 3D printed kit, which is able to detect the presence of a biomarker of Aflatoxin B1 (a

Nanoparticles in antitumor therapy

One of the most common cause of deaths are various tumor diseases. Tumor cells often appears to be not vulnerable for some drugs. That is why developing therapies which includes many diffrent mechanisms of work are very important.In my studies I was trying to synthesize iron oxide extrimelly small rounded shaped particles which could handle three different mechanisms of killing tumor cells. Firstly they have special magnetic properties which, allows us to local incresing temperature thanks to variable magnetic field. So we could in some way "boil" cells. Secondly I tried to admixture radioactive element. And thirdly I connected the

Narrow-band Photometry of Emission Nebula Using Small-Caliber Optical Telescope

The emission nebula is very common in interstellar matter, and its continuum has several obvious emission lines. In order to study the chemical elements in the emission nebula, this paper uses a small optical telescope with Hα, [SII], [OIII] narrow-band filters to select four emission nebulae for observation. A lot of results can be obtained by analyzing the experimental data. For example, in most of the emission nebulae, the content of Hα is much larger than [SII] and [OIII], and in the supernova remnants, the content of Hα is less.

Neural Network application to key-point-detection in radiographs

Occasionally, physicians have to measure certain bony structures of a patient precisely and locate so called key points e.g. for purposes such as surgical procedures. Up to now, the radiographs were usually analyzed manually. With increasing frequency, classification tasks are done by a computer in an automated process. In order to automate the key point detection on radiographs, Constantin Tilman Schott developed innovative software that uses artificial intelligence (AI) to identify these important key points. His program uses self-learning algorithms to perform this task. If enough training data is provided, the program can predict the key points with a high

Next generation of solid-fuel rocket engines

Using of powdered fuel is almost impossible during all history of rocket engines. It burns so fast that the gas pressure destroys the engine’s casing. To solve this problem the fuel is pressed usually and an inhibitor is added. In my research I developed a new technology of controlling pressure inside the solid-fuel rocket. It simplifies greatly the process of making engines, allowing adjusting their parameters to get the maximum thrust safe pressure inside engine. Using this technology I created a working small engine for rocket modeling. It was tested and works well in real flights. I will continue the

Targeted drug delivery has become popular for its main advantage to differentiate between healthy cells and cancerous ones. However, targeted drug delivery still has problems to overcome and one of them is the need of new, promising materials for drug encapsulation.We present novel polymer, which forms micelles in aqueous solution and provides a hydrophobic reservoir for Water-Insoluble Drugs. We claim to achieve complete biodegradability and non-toxicity of micelles as well as high stability below CMC and long blood circulation

O da la miúda. Distribution, ethology and phenology of the Iberian wolf.

In order to obtain data on the distribution and behavior of the Iberian wolf in the study area(Mountains of O Xistral and surroundings), a methodology different from previous studiescarried out in the province of Lugo is used where the IKA indexes do not represent a tool toconfirm the presence of the groups, but a method prior to the photo-trapping of specimenswith which more accurate data is obtained and that would allow to assess the populationtrends of the Canis lupus signatus in the area. It has been confirmed the existence of three 3packs and other 3 are pending to be corroborated

On the Common Prime Divisors of Polynomials

We inspect those polynomials whose coefficients are integers. We say that an integer m is a divisor of a polynomial P if some value of P is divisible by m. Our main result is that the common divisors of any several polynomials are exactly the divisors of a single polynomial. This is extended to prove that the set of prime numbers for which a system of polynomial equations in multiple variables is solvable is exactly the set of prime divisors of some polynomial in one variable. In addition, we prove results on how often a prime number is a common

On the number of points on an algebraic curve in a ring of residues

In our paper we obtained the following results: 1. We introduce a new function R_(f,I) (n), which is the number of all possible combinations of giving coordinates of the solutions of the congruence f(x_1,…,x_k )≡0 mod n, and proved that this function is multiplicative. 2. We obtain the exact number of points on a curve x^m-y^k≡0 modn. 3. We introduce a new definition m/k-power residue modulo n and found an exact formula for their number modulo n. From this formula as a corollary we obtained the full results about m-power residues. 4. We calculated the number of points on a

Prevention of Cheating in eSports

eSports are a rapidly growing industry, and thus, there is a lot of attention drawn to it lately. One hot button issue is cheating. As with other more traditional sports, doping is also present in eSports, however with the sport moving onto electronic devices comes a new way - cheating using digital programs aimed to give the player an unfair advantage. In my project I have researched the various cheating methods, and created various solutions to detect and prevent players from using such things to their advantage.

Prunosom from leaves to anti-age creams: the magic of liposomes and vegetable antioxidants

Vegetables substrates, because of their antioxidant powers, are being used by pharmaceutical, cosmetic and food fields.We analysed the quali-quantitative composition of total flavonoids, anthocyanins, flavanols and HCTA retrieved from leaves of Prunus Pissardii (a very common plant in Europe), which provided the most significant amount of antioxidants. With the retrieved extract we produced a cream, which allowed us to exploit Prunus antioxidant and antiradical powers. To improve cutaneous absorption we decided to encapsulate the antioxidants inside liposomal nanocarriers, used as drug delivery system. Our project has a high eco-sustainability as the chosen vegetal substrates are waste materials, thus reducing their

It helps people not understanding Russian politics fully to imagine the idea of them as well. For people who already know Russia’s

Pythagorean Quintuples

Pythagorean quintuple is a quintuple of five numbers a,b,c,d and e corresponding to the equation a^2 + b^2 + c^2 + d^2 = e^2. In the first part of the research, several different parametrizations of natural Pythagorean quintuples were discovered. Using the parameter selection, a Pythagorean quintuple is obtained, so the generator of Pythagorean pentacles is also called parametrization. The generator that generates all Pythagorean pentacles was discovered and also proved.In the second part of the research, in the set of the whole Pythagorean quintuple the multiplication was defined. It was proved that there is a multiplication unit, and that

Reduction and visualization of high-dimensional systems

The method described is applicable to quick visualization of high-dimensional systems as well as a general, system-independent model capable of significant optimization in studying large classes of complex systems. With the help of the solution an arbitrary high dimensional system with a number of derivatives studied can be stored like we were only studying 3-dimensional series. Even for small sytems the storage requirement can be decreased with two orders of magnitude. The reconstruction time is less than 0.07 % of that of the time needed for the direct, classical evaluation, this time is quickly decreasing with the number of elements.

Remote Controlled Cylinder

This research work consists of the conception and open-source development of a robotic cylinder whose speed is remotely controlled through a web page. To induce the movement, an innovative approach has been developed, which uses the coordinate movement of three motors to move a mass inside the cylinder. As the mass is placed away from the center, an imbalance is induced, causing the cylinder to accelerate. This project is very transdisciplinary, which is what makes it especially interesting: mathematics, physics, mechanics, electronics and programming notions were necessary to build the final prototype. It weighs 1.4 kg, has a diameter of

The aim of my project was to create a homemade experimental stand (following Foucault’s idea) and to show that physics can be breath taking. My project allows seeing different gases, air currents and movements, a breath or even sound waves. With the use of a special apparatus consisting of a mirror, a video camera, an LED light, and a razor blade, it is possible to see something that a bare eye cannot, such as warmth coming from a hand. All thanks to the occurring physical phenomenon like refraction, the

Synthesis Of A Water-soluble Fluorescent Dye For Labelling Normal And Cancerous Urothelial Cells Of The Urinary Bladder In vitro

Our research was aimed at differentiating between healthy (normal) and cancerous urinary bladder urothelial cells. We developed a fluorescence derivative of fluorescein, sodium disulfonate (SUF), which is an organic compound and emits intense fluorescence. We analysed if SUF can be used in cancer cell diagnostic and examined its potential for targeted therapy as an alternative to the currently used fluorescent dyes, which are more expensive and harder to obtain, and with this approach make such research more accessible. The results of the study have shown that SUF is not toxic to urothelial cells of the urinary bladder and that it

Taking ABiTE out of Cancer: A Novel Aptamer based BiTE for Cancer Immunotherapy

Immunotherapy is a treatment in which the body’s own immune system is stimulated to fight diseases such as cancer. One treatment, called Bi-specific T Cell Engagers (BiTE), consists of two antibodies linked together. One antibody binds to a T cell, while the other binds to a cancer cell, helping T cells recognize and kill the tumor. Unfortunately, BiTEs have several limitations. In a previous project I used aptamers – short single strands of DNA or RNA – to create a disease diagnostic tool. I wondered whether aptamers could make BiTEs more effective and reduce their side-effects. I designed three different

The action of prednisone, sodium chloride and microwaves on living organisms

Taking into account the benefits and adverse effects of using prednisone acetate - anti-inflammatory and anti-allergic cortisone derivative - we studied its effects in combination with salt. Salt affects the growth of plantlets at a concentration of 5%. Higher values are obtained in the case of plants treated with a mixture of prednisone acetate and microwaved non-iodised kitchen salt compared to those treated with prednisone acetate and non-iodised kitchen salt. People under medication with prednisone acetate could consume small amounts of salt subjected to microwaves. Using MM +, Monte Carlo, a RMS gradient of less than 0.1 is obtained for

In this work I have investigated the ovoposition behavior of bean beetles over four generations. The purpose of this work is to investigate whether the bean beetle will prefer to lay eggs on the bean, mung bean or adzuki bean, they were born from for four generations. I was interested in exploring which of the beans, mung or adzuki, the bean beetles would prefer to lay eggs on and if there would be an increase in egg laying on the bean they were born from. The method used in the investigation involves on raising four generations of bean beetles, one

The Church of Stalin

A dramatic shift of Stalin’s policies had significant impact on the Soviet society during World War II. Stalin decided to tolerate the Church playing a greater role in the war after a decade of systematic repression. The focus question of this essay is “How did the role of the Russian Orthodox Church change between 1941 and 1945?”. This essay will examine multiple perspectives including economic, social and political reasons for Stalin’s decision in regard of the Second World War. When looking into the significant shift, 1941 stands out because the Church was again allowed to operate. Whereas 1945 marks the

The Design of Computer Controlled Refractometer

In this project, we aimed to design a computer-controlled refractometer with the basic tools we had. For this purpose we used a hollow glass prism which is filled with a liquid whose refractive index to be measured. We placed this prism on a stepper motor in front of a laser module. So the laser beam refracts as it passes through this liquid and falls to the screen on the other side of the prism with a deviation. To determine angle of this deviation, we used a webcam. We adjusted the angle of incidence of the beam by rotating the stepper

The dream of the sound

The invention of a device for deaf people. Why did we choose to do this project and how did we do it?Firstly, my friend’s grandfather is deaf so this cause was very involved to her because she wanted to make him smile again. First of all, we have researched the subject because «sound» is a very vast environement. Then, we found some informations about what sound was and we made a lots of experiments on tis subjet.Finally, we moved on the practical part, we welded and assembled everything so that the project worked. To conclude, our project is to make

The effect of the E12 antibody on multiple sclerosis

Multiple sclerosis (MS) is an autoimmune disease in which immune cells attack neurons. When an immune response terminates, memory cells remain in the body in order to respond more effectively in future encounters. Previous studies found that the E12 antibody can increase differentiation of T-cells into T-type regulatory cells (Tr1), that secrete the cytokine IL-10 which represses abnormal immune responses. Our research examines whether E12 can increase their differentiation into memory cells. MS mice models treated with E12 showed substantial a reduction in clinical symptoms, and an increase in memory cells and IL-10 secretion compared to control. This indicates that

The aim of the research is to explain the diluting effect in mane and tail of the PMEL17 mutation which is also associated with several eye disorders (MCOA syndrome) e.g. cysts and cataracts. In addition to the studies about individual horses, the research offers a possible reason to the wide range of Estonian horse coat colours and gives a possible answer to the origin of the Silver gene in its genotype. Furthermore, the research tries to

The Invisible Pollution of Sea Water

This project began on a beach, with an experiment, triggered by an image to become a concept: The Invisible Pollution of Sea Water. We thought of microplastic, quite nefarious, invisible and so abundant that removing it from the sea is highly challenging. This project is a driver for evolution, shifting mentalities and fostering social and scientific changes in unconventional ways; by engaging the community, you not only build a cheap and doable underwater remote operating robot / vehicle (ROV) or provide data for scientists, manipulate equations and laws of STEM found everywhere in our ROV but also interact and send

The link between body thermal expression and the trauma presence: quick, cheap, easy, and safe diagnostic approach

Our experiment is based on thermographic scans that were used to study occurrence of serious trauma in professional athletes. We investigated professional basketball team players, therefore, an information about their health or upcoming injuries was interesting and helpful not only for us but also for the players involved. We performed front and back thermographic scans with the camera FLIR Tools 640 before and after exercises. Our investigation proved, that thermographic scans are sensitive, specific, and valuable information in order to prepare effective recommendations for the athletes. Our method is quick, cheap, easy, and safe diagnostic tool that can be used

The Perfect Europe Dinghy Sailor

The project explores how to become The Perfect Europe Dinghy Sailor. Therefore, the project presents the physics of sailing with a primary focus on the aerodynamics. A model of the Europe Dinghy is designed, and an experiment analyzing the force generated by the sail is performed in a wind tunnel. At last, a complex model is developed to quantify the subjective decisions made while sailing. In the light of the theories, the project finds that the physics of sailing can be described with Bernoulli’s principle. Furthermore, the project reveals that Europe Dinghy sailing is primarily influenced by an isometric muscle

The wingtip’s influence on the efficiency of airplane wings

Aviation is one of the most important ways of transortation. However, it is highly energy consuming and has a substantial climate impact. In this project, I have designed and tested a new type of wingtip device called a New Raked Wingtip. The New Raked wingtip optimizes the three-dimensional flow around the wingtip in order to maximise the lift and minimise the drag on the wing. That is, maximising the wing's efficiency defined as the ratio between the lift and the drag. Experiments that I have designed and carried out show that the New Raked Wingtip not only increases the efficiency

Triboelectric Curtain

This is an eco-friendly electric station producing enough green energy in an unique way from wind at any time of the day. We take one couple of materials: one has a negative charge and the other has positive, then we place a conductor on each of them. When they touch each other, they exchange charges. After these 2 sides get separated voltage between them rises. This is “Triboelectric Effect” but we discovered that here also works electromagnetic field. When curtains are exchanging charges, they move to each other & vice versa, but mostly this action is accelerated, so we get

UVI Wristwatch (UVW)

The ultraviolet part of the sunlight can damage the human skin by sunburn depending upon the radiation intensity. For people who are heavily exposed to sunlight (beach tourists, sailors, mountain hikers), it would be useful to know whether the current UV radiation they are exposed to can cause sunburn. Ideally, these people would carry a small measuring device with them that gives them continuous information about the intensity of UV radiation. It can be shown that open source hardware and software, 3D printing and a smartphone app are already sufficient to realize such a UVI measuring device in the form

Wave-particle duality: an experimental test of Compton’s theory

The aim of my project was to test Compton’s model for the interaction between electromagnetic (EM) radiation and free electrons. Compton’s development of this model was of great importance for the understanding of the wave-particle duality. It is based on a particle model for EM radiation, which in classic physics is interpreted as waves. I tested the model by analyzing scattering in the angles between 60 and 120 degrees. The results in the angles above 70 degrees corresponded well with the model, and the deviations in the lower angles could be explained by systematic sources of error. Thus the results

With Death at His Heels. Chronicle of an Escape and Two Wars.

Based on a recording made by the protagonist himself, I have tried to reconstruct Miguel Quintillà’s biography. A member of the Republican Council of Purroy (Spain), he managed to escape execution by the Guardia Civil in 1938 and became a republican combatant in the Segre and Ebro battles. Prisoner by Franco, he managed to escape in the Navarre Pyrenees. He joined the French Légion estrangère and fought against Hitler during the 2WW in the battle of the Norwegian fjords. He was also a soldier of the NOSC of the British Army, which landed on the Normandy coast.My analysis it’s an
