Simulation of Tasks Distribution in Horizontally Scalable Management System

This paper presents an imitational model of the task distribution system for the components of territorially-distributed automated management system with a dynamically changing topology. Each resource of the distributed automated management system is represented with an agent, which allows to set behavior of every resource in the best possible way and ensure their interaction. The agent work load imitation was done via service query imitation formed in a system dynamics style using a stream diagram. The query generation took place in the abstract-represented center - afterwards, they were sent to the drive to be distributed to management system resources according to a ranking table

Designing of routing algorithms in autonomous distributed data transmission system for mobile computing devices with 'WiFi-Direct' technology

The results of the research of existent routing protocols in wireless networks and their main features are discussed in the paper. Basing on the protocol data, the routing protocols in wireless networks, including search routing algorithms and phone directory exchange algorithms, are designed with the 'WiFi-Direct' technology. Algorithms without IP-protocol were designed, and that enabled one to increase the efficiency of the algorithms while working only with the MAC-addresses of the devices. The developed algorithms are expected to be used in the mobile software engineering with the Android platform taken as base. Easier algorithms and formats of the well-known route protocols, rejection of the IP-protocols enables to use the developed protocols on more primitive mobile devices. Implementation of the protocols to the engineering industry enables to create data transmission networks among working places and mobile robots without any access points

Research of GIS-services applicability for solution of spatial analysis tasks

Experiments for working out the areas of applying various gis-services in the tasks of spatial analysis are discussed in this paper. Google Maps, Yandex Maps, Microsoft SQL Server are used as services of spatial analysis. All services have shown a comparable speed of analyzing the spatial data when carrying out elemental spatial requests (building up the buffer zone of a point object) as well as the preferences of Microsoft SQL Server in operating with more complicated spatial requests. When building up elemental spatial requests, internet-services show higher efficiency due to cliental data handling with JavaScript-subprograms. A weak point of public internet-services is an impossibility to handle data on a server side and a barren variety of spatial analysis functions. Microsoft SQL Server offers a large variety of functions needed for spatial analysis on the server side. The authors conclude that when solving practical problems, the capabilities of internet-services used in building up routes and completing other functions with spatial analysis with Microsoft SQL Server should be involved

The economic efficiency of european football clubs - Data Envelopment Analysis (DEA) approach

The relevance of this paper lies in the fact that football business has grown significantly in the past 20 years and football clubs have become large companies, which in an effort to be profitable and successful on the field need to improve the efficiency of their business. The aim of this article is to measure economic efficiency of 48 big European football clubs and assess the relationship between efficiency and different financial and sportive indicators (variables). To measure efficiency, we used both widely used Data Envelopment Analysis (DEA) method and its extensions: DEA Super-efficiency and DEA Cross-efficiency models. The results showed that these methods can successively be applied to football clubs’ efficiency measurement and the analysis of the them can help to explain why some clubs are efficient or inefficient and which factors affects the efficiency. This paper will be interesting football clubs’ managers, football analytics, economists and other people interested in football business because we combine in it the most interesting ideas and methods about football clubs’ efficiency measurement. © 2016 Pyatunin et al
