Methods to solve the problems of the comparative assessment and selection of unmanned aerial systems are offered. These methods are based on the particular indicators that display the efficiency of unmanned aerial system application. An algorithm that helps to solve such problems has been developed to create a system of support and decision making and to optimise the distribution of resources. © 2013 Vilnius Gediminas Technical University (VGTU) Press Technika.

Actual consumption of vitamins A, E, β-carotene, ascorbic acid, thiamin, pyridoxine and main foodstuffs by recovered patients suffered from hemorrhagic fever with renal syndrome has been given. Frequency analysis of foodstuffs consumption was used to study actual nourishment of recovered patients. Surplus consumption of fat mainly due to the use of saturated fatty acids, deficiency of poly unsaturated fatty acids, surplus sugar consumption and predominance of proteins of animal origin over proteins of vegetable origin in ration has been revealed. Deficiency of water soluble vitamins equals to 41,6-78,7% of all examined patients, deficiency of fat water soluble vitamins is lower (21,4-38,3%).

One day, rogue asteroids may crash into Earth and cause significant destruction. Getting rid of the cosmic object before it gets near is one measure to prevent the event and its potential massive dangers. To fulfill the job, the European Commission tasked Russian scientists represented by Roscosmos' Central Machine Building Research Institute to develop a plan for nuking rogue asteroids. For Russian experts, the most effective strategy to prevent an asteroid from crashing to the Earth is a nuclear explosion. Using nuclear weapons have long been banned under the Outer Space Treaty of 1967. However, Russian scientists believe that there is an exception if Earth is in an impending danger. "If the asteroid threat becomes a matter of serious damage or even the very existence of life on earth, that ban would naturally be lifted," said the institute. The objective is to change the course of the asteroid's path away from Earth instead of directly attacking it. When a nuclear explosion occurs near an asteroid, it would burn up some parts of the cosmic object, creating a jet-thrust effect. Such impact would initiate a significant change in the orbit of the asteroid. To minimize the danger, it is best to discharge the missile while the asteroid is still far from the planet. With such a plan in place, the Russian scientists said it would create a specialized software to monitor asteroids coming near the Earth. The Russian project would also entail four observation satellites. Two of the satellites would track the planet's orbit around the sun and the other two would monitor stationarily around the planet's orbit. The EU program called NEOShield consists of different projects that involve various nations. The aim of the project is to work on different strategies to prevent the collision of Near Earth Objects. "Final results are expected in May 2015, but the project has already triggered the interest of the international press," the European Commission says. The Central Scientific Research Institute of Machine Building or TsNIImash is one of the leading developers of space technology machines in Russia. The firm is said to be part of the testing and experimenting the processes of nearly all Russian space launchers and vehicles.

In this article, a methodological approach based on a complex indicator (productivity-cost-efficiency) to evaluate the efficiency of using unmanned aeronautical systems is presented as a solution to the problem of searching for objects on the ground. This methodological approach can be used as a substantiation of decisions taken during the act of searching for specific objects and as a comparative evaluation of unmanned aeronautical systems by taking into account their characteristics. © 2012 Vilnius Gediminas Technical University (VGTU) Press Technika.

We propose an invariant adaptive technique for automated segmentation of a target-and-background frame from an optoelectronic device for detection of dynamic objects in the image. The technique involves performing a wavelet transform on the image such that threshold processing of wavelet coefficients is optimum (in the sense of the Neyman-Pearson principle) based on a very powerful local unbiased test, and does not require any a priori data on the target environment, any reference images of the dynamic objects, or the locations and dimensions of the windows used for object detection. This is implemented solely using the information contained in images recorded by the optoelectronic device. We present an algorithm and results from an assessment of segmentation quality statistics for non-steady-state (and steady-state) images under various operating conditions. The technique described in this paper is found to be highly efficient and can be implemented as a real-time algorithm. © 2016 Optical Society of America.
