The research focuses on the generalized traveling salesman problem, which arises in a number of applications such as

defragmentation of computer hard disks, industrial robot control and others. In contrast to the classical formulation, the given

set of cities is divided into several groups (clusters), and the problem is to find the shortest route for a salesman who must visit

only one city from each cluster and come back to the first one. Besides, it is assumed that the clusters may consist of the cities

from different geographical regions, and the distances between the cities do not satisfy the triangle inequality. For this problem

of extremely high computational complexity, a new efficient heuristic algorithm is proposed that can be run on a standard PC.

Efficiency of the developed algorithm is confirmed by computational results and an application example (optimal motion

planning for industrial robotic welding system).

Formation and dynamics of active galactic nuclei jets are one of the main problems of modern astrophysics. There are no

completed theories that explain jet curving in halo on large distances from parent active galactic nucleus. Therefore the model

of explanation of this unknown phenomenon is created in this project.  Radio galaxy 3C 31 is taken in the model as the best

example of jet curving. According to my assumption this effect is happened because of dark attracting matter (DAM) changes

of jet trajectories. In this research paper DAM mass is estimated for five parts of 3C 31 radio jet. I used analytical, computer

modeling, and image processing methods. I obtained high limit of DAM mass, which is equal to about   solar mass. This result

is in good correspondence with data obtained with world largest telescopes (VLA, Chandra, etc.). 

A soliton is a nonlinear solitary wave, which saves its form and velocity during its motion and interaction with other similar

waves, in other words it is a steady structure. (A Tsunami wave is a solitary wave too).

A number of works have been published, which are dedicated to this topic and offered some more equations, describing

nonlinear solitary waves; but no experimental research of the nonlinear solitary wave shape. A new procedure for regaining the

solitary wave front is proposed, that may be applied to a large variety of hydrodynamic experiments.

An automation solutions provider based in Austria, sought a technically demanding solution: the control module displays were

no longer visible in the recently acquired PCB pin testing system. The colour and position of the LEDs still needed to be checked

to detect any mistakes made by the automatic insertion equipment. Operators are not able to check the PCBs visually because

the angular pin adapter is fully enclosed and the design also prevents a function test from being implemented electronically.

This is where this project comes in. The result is an innovative image recognition system that represents a considerable part of

the final check of the product, contributing to best-possible quality and reliability. Moreover, the automated testing system

achieves considerable savings in time and costs.

Mira is passionate about astronomy and space. Her project focuses on the effects of gravity (or the absence of gravity) on the

human body. More specifically Mira investigates the influence of the gravity on the functioning of a human heart. Therefore she

analyses the heart activity of a parachutist during a free fall and of a Belgian astronaut (Frank De Winne) during his stay on the

International Space Station. Although the results of both experiments firstly seem to be at odds, Mira demonstrates that the

heart beat decreases in weightlessness conditions.

Several science museums around the world exhibit Tesla coils since this dazzling device, firstly designed by N. Tesla in 1890,

generates impressive electric discharge. David, Antoine and Nicolas wondered whether they were able to build such a device by

their own. After checking their textbooks and the Internet, they processed by trial and error and finally found their own solution

for each element. Especially they designed an original setup for the circuit switch (the sparkgap). 

When succeeding in an operational prototype, David, Antoine and Nicolas investigated the physics that govern a Tesla coil and

confronted the theory with their observations.

This project presents an environmentally friendly alternative variant of the fuel cell type of source of electric energy. Its

operating principle is based on a mechanism taken from living organisms. 

A prototype of electrochemical source of electricity called Direct Aluminium Quinone Cell (DAQC) has been designed and a

number of experiments have been conducted with the prototype. Also, a multimedia presentation has been developed to

demonstrate the project. 

The power rate of the cell has been determined by taking the current-voltage characteristics under various experimental

conditions and by choosing suitable loads to demonstrate its operation. The improvement of these characteristics is the goal of

our intended research since fuel cells hold much promise for future development.

A comparative analysis of two models of a ball bouncing from a hard flat surface are presented in this study: the model of a hard

ball (Walton’s model) and a model developed by the author, which is an elastic ball. The “opposite” torque of the normal

reaction during impact prevents the transformation of the initial energy of the ball into rotational energy, due to the existence

of contact area of finite size between the ball and the surface. This allows more efficient transformation of the energy of

translational motion in horizontal direction (parallel to the surface) into that of motion in vertical direction (perpendicular to

the surface), i.e. bouncing with coefficient of normal restitution.

The aim of this research is to show the results of amateur observations of the variable star RZ Cassiopeiae and the calculation of

the O-C effect of the eclipsing binary RZ Cas, as well as an attempt of estimating the parameters of the hypothetical third

companion, such as its orbit and mass.

Numerical data collected were for about 2700 primary minima observed from the discovery of the star as a variable till today. The purpose

of the analysis was to study the hypothesis that the variation of the O-C effect is due to the existence of a third body in the system. Our

calculations for the radius of the orbit and the mass of the third component are based on a simple theoretical model of the system. Finally

we come to the conclusion that if a third companion exists, it should be a low mass star – a red dwarf. Since the system is located at

about 64 pc away from us and the maximal angular separation between the binary star and the faint red dwarf is several tenths of an arc

second, a direct observation of the third star would be almost impossible even by the most powerful instruments existing today.

For the purpose of transferring waste into material sources and finding the low-cost and effective absorbent materials, several

tests were done separately for the absorptions of five adsorbent materials of the heavy metal Cr (VI), such as the Active Carbon,

the pulverized fuel ash, vermiculite, the dregs of honeycomb briquette and the brewer’s yeast. 

Compared with traditional methods, using the waste brewer’s yeast to treat the chromate-contained industrial wastewater is far

less costly, and what’s more, the absorptive effect of the brewer’s yeast has no secondary pollution.

Diabetes mellitus(DM) is a disease of endocrinopathy which is characterized by abnormally high level of sugar (glucose) in the

blood. Failing to produce insulin, insufficient insulin level, or ineffectiveness of insulin may induce this. Type 1 diabetes, which

is an autoimmune disorder, is more common than type 2 diabetes which is associated with obesity. The number of people with

diabetes in P. R. China is almost 50,000,000 and about 2,000,000 new cases are diagnosed each year. Edible fungi or mushrooms

as Chinese traditional medicine and invigorant, have many kinds of bioactive substances such as lectin, ribonuclease,

polysaccharide and etc. Corduceps militaris is a very famous edible fungus used for several thousand years in China but hardly

known for hypoglycemic activity. In this study, the polysaccharide was isolated from Corduceps militaris and showed a

remarkable anti-diabetes activity.

The objectives of this work were to detect fungicidal effects in some plant extracts and their mixtures against fungal diseases of wheat

and barley, to test various extraction methods, to determine optimum concentration of such extracts, and interactions between the

effect and environmental conditions, such as temperature. The fungicidal effect was tested in glasshouse and field experiments. 

The effectivity was significantly increased by the adition of surface activator GREEMAX or olive oil to the plant extract solution. 

Treatment of winter wheat plants with extract of wild garlic developed a significantly lower rate of leaf rust (caused by Puccinia

recondita) at flowering stage  as well as a less infection by scab (caused by Fusarium culmorum).

This project concentrates on the dynamics of small ponds and their possible function as refuges to the plant communities

forced out from the cultivated landscape. It tries to integrate the historical and botanical approach to the problem. While doing

historical research of the sites, the reconstruction of development of vegetation in past decades was attempted together with

identification of conditions that influenced this development. The main aim was to understand some of the actual phenomena

affecting the small ponds in general. Special attention was given to expansions of some grass species degrading natural littoral

biotopes as well as to the impacts of eutrophisation of ponds and their banks. Possible steps leading to the maintenance of

biodiversity were considered and local authorities showed interest in the use of the results in their conservation conceptions.

The project inquires into graph theory, an important part of discrete mathematics. Colouring a graph means to map the vertices

of the graph to n colours so that no two neighbouring vertices have the same colour. The project proposes and studies a

generalisation of graph colouring that allows to define relationships between colours. 

Homomorphisms, like colourings, have applications in problem-solving. Many problems, for example assigning

frequencies to transmitters so that no two neighbouring transmitters interfere, can be formulated in the language 

of graph homomorphisms.

The project “genetically modified organisms” (GMO) describes how revolutionary biotechnology can be in a society like ours.

Starting from some relevant research experiments carried out at the “Research Centre Flakkebjerg” and including my

experiments described in “Genetic Engineering and Cloning”, this project describes how these techniques can be used to

produce GMO. The purpose of describing both practical and theoretical aspects is to provide a clearer and more concrete

knowledge about what GMO and genetic modification (GM) actually is, thus enabling the reader to understand more clearly

the implications of the technology.

Some current research experiments with GM crops are described to illustrate the potential of this technology for society and

how it could be utilised to alleviate problems all over the world, e.g. in agriculture and in the production of food and medicine.

This project presents simple aid for putting on and taking off socks and stockings. Unlike the existing products, this one can

also be used for taking off stockings – a daily arduous and difficult task for many newly operated, handicapped and indeed also

the physically handicapped persons worldwide.

In particular, taking off socks or stockings has resulted in many falls and this has resulted in the admission of a number of elderly,

handicapped and physically handicapped persons to hospital. Since the person while sitting down can use this aid, the using of

my product would reduce these accidents and thus also result in savings within the public/private health sector.

The aim of research is to study the impact of school and pupils' social origin on their justice beliefs. Empirical analysis is based

on sociological data gathered by the author in three secondary schools in Estonia. These schools differentiate by their

specialization, admission rules, foundation time, social origin of their pupils etc. The questionnaire composed by the author

includes questions, which have been used in several international studies. The analysis indicates that the school and social origin

have impact on pupils' support for egalitarian principles. 

Most information we take in about the world around us comes to us through our eyes. A scientist worked out that 80% of

everything we remember is something we have seen. As children we learn to associate certain shapes and colours with certain

objects, even people with slightly impaired vision can make out the shape of a flower or a ball if it is shown to them. The goal

of this project was to find out exactly what percentage of an image needs to be shown, before am image can be identified and

to try and gauge the significance of colour in visual acuity. Our hypothesis was that colour and shape are the two main factors

involved in sight and that where these factors are unclear, visual acuity becomes greatly impaired. Study of the data has proven

both of these theories to be true, especially among people with poor vision.

This project analyzes the generalizations of the Fibonacci sequence with the recurrence relation U

n

= pU

n-1

+ qU

n-2

.  It shows they have

much in common with the original sequence, especially when the starting elements are fixed to be the same. Two very useful formulae

are proven that allow many others known for Fibonacci numbers to be generalized for our sequences. These formulae also allow us to

show that the generalizations share certain divisibility properties with the original, especially if p and q are chosen without a common

divisor. Lindenmayer systems are also investigated and shown to have a connection with our sequences under certain assumptions. 

Around Kohtla-Järve in County Ida-Virumaa there are several different technogenic landscapes that have arisen during the

decades of continuous mining and processing of oil shale. The interest in orchids came up when we heard that those beautiful

flowers have been found on the ash-mountains created by the chemical industry. We were interested, if orchids are also growing

on other technogenic landscapes and how they might have gotten there.
