The article considers the issues of architecture of sea rescue automation facilities set. The automation facilities set must provide data support for task solutions by operation control of Navy search and rescue aid while preparing and reali-zation of sea rescue. The article describes typical software and hardware complexes as structural elements of automation fa-cilities set needed to create architecture. A facilities set architecture is hierarchical multi-pillar system which covers control posts (search and rescue posts) on different levels and emergency rescue units according to their areas of responsibility. The article determines types of objects for automation facilities accommodation, total amount of typical software and hardware complexes and quantity of complexes of each type needed to create a system.

A redundancy-based method providing a required level of functional reliability of radio-electronic equipment control systems is given. The reliable task solution probability is chosen as the reliability index. The formula for calculating the probability of the reliable task solution is proposed. It considers soft errors and hard faults. The redundancy optimization problem is formulated. An objective function for the optimization task is designed and converted to the form suitable for the bivalent programming. It includes boolean variables. Exact and approximate methods of optimization are realized in MATLAB. The formulas for calculating average time of the optimization using exhaustive and heuristic methods are given. Accuracy estimations of the heuristic methods are given.

The article considers a presentation form of structured data in relational database taking into account condition of search-and-rescue resources information specificity – data are presented as a tree-structured relation. In this case tree-structured relation has a limited quantity of nesting levels and various entities of tree nodes. The article shows certain de-scription methods of the similar structure type in relational database analyzing each method and recommending the presenta-tion form of that kind of structure in a relational database. While choosing presentation form it is necessary to implement such data in software equally as a folded tree and as un-folded structure.

A local query optimization is an integral part of a database efficiency problem which is as relevant as ever in electronic. Its solving quality affects local queries performance optimization as well as more global optimization levels of da-tabase management systems. There are a lot of methods of local SQL-queries optimizing for relational and object-relational databases. The most of methods focus on lexical optimization, a reducing conversion of search conditions expressions (ab-sorption algorithms and logic expressions minimizing algorithms). In real databases there are different methods are optimal. One of the main tools to increase data retrieval productivity in relational database tables is to create indexes. The article gives a brief overview of the methods of query execution plans optimization and ranking criteria for these plans with a focus on the indexes appliance analysis in query performance improving. The special features of different indexes possible appliance are considered using an object-relational database management system PostgreSQL and Oracle. The article offers a method of improving local SQL Queries efficiency. It based on the joint optimization of WHERE sec-tion logical expression and a list of expressions ORDER BY section of SELECT query command in SQL with a list of com-posite index expressions. There are special conditions for its efficiency. The article shows a formal algorithm description that represents this method, and the simplest, yet affordable for a reader, example for assessing the method efficiency and its ap-propriate use.

The paper describes basic features of software implementation for «Virtual Surgeon» simulation training sys-tem for surgeon’s study of laparoscopy (endoscopy) skills at stages of pre-graduation training and graduation work. The de-veloped software allows realistic simulation of different laparoscopic instruments actions and video camera – endoscope in 3D scenes. There are developed 3D models of human body and operative intervention scenarios that help learning basic skills and techniques of surgery treatment. Special scenes and study methods are provided to train surgery basic skills.

The paper analyses the process of complex application development that uses GIS-technologies to manage and control cocoa pest and disease spread in a West African country: Ghana. The complex program captures information about detected pests and diseases. This information can be examined by agricultural extension officers on farms, warehouses and plantations of different zones and districts. This information is also published on the web and can be accessed by stakeholders (Govern-ment Ministries and Agencies, non-governmental organization etc.) through an interactive web-based GIS interface (interac-tive map).

The article describes computer vision system software for assessment of firing process in rotary cement kilns. The software implements a specially developed method of firing process image recognition allowing real-time automatic as-sessment of the firing process in three parameters: dust, condition of the material and condition of the torch. Recognition method includes the image pre-processing with the texture features matrix construction for image areas; an image partition with a self-organizing map construction; informative features vectors formation on found segments; finding the vector of fir-ing process assessments on the basis of an informative features vector classification using a three-layered neural network learning with the extreme learning machine, with one layer hidden. The software package includes images database and four interactive forms: the form of the operator, the form of program settings, the form of images history and the form of the im-age recognition algorithm settings.

A numerical model of non-cohesive soil deformation calculating is developed On the basis of modern elasticplastic Dafalias-Manzari model, implicit Euler method and the iterative Newton-Raphson scheme. The numerical implementation of the model on the computer is executed. The simulation of the sand behavior at a monotonic and cyclic loading is carried out. The calculation data and experimental information for sand with various compactness were compared. The computational model definitely describes sand behavior with monotonic and cyclic loading. The results of the theoretical prediction of the sands stress-strain state under monotonic and cyclic loading show the efficiency of the computational algorithm. They allow recommending this prediction for finite-element analysis for geotechnical problems solving.

The article describes the simulation software of the human hypoxic conditions dynamics according to health risk metrics and human performance in terms of low barometric pressure (high altitude flights, mountaineering, space, etc.). The hypoxia dose mathematical model as the integral intensity of hypoxic impact within the time of this factor activity allows passing into the dynamic area of study the effects of hypoxic gas environment (to size up its impact on the human condition in real time). It allows calculating the buffer time of human efficiency saving in conditions of hypoxic hypoxia and recovery time after cut -off of. The developed model provides calculation of probabilities adequate valuation of adverse effects with any velocity profiles and oxygen partial pressure in a trachea, multiplicities and exposure time of hypoxic outward influence. A mathematical model verification based on the results of computer simulation using data from real aircraft cabin depressurization incident with the Tu-154. These results provide decision support when choosing the optimal flight path of aircrafts in the case of cabin depressurization, in assisting the injured and affected in emergencies in the high altitude and in a number of other problems associated with the presence of human beings in hypoxic hypoxia.
