In this work it was explained why the energy balancing in a static wireless sensor networks with autonomous energy sources is actual nowadays. We presented mathematical model of static wireless sensor network which considers external influence. We presented method of energy balancing in a static wireless sensor networks with autonomous energy sources and experimental results which show increasing work efficiency of static WSN with autonomous energy sources by increasing nodes lifetime and decreasing nodes energy consumption.
Issues of ex post evaluation of mergers and antitrust bodies prescriptions are discussed. Among them: interrelation of enactment and enforcement from the perspectives of errors of I and II types in antitrust mergers control; probable consequences of mergers for competition; Аннотации к статьям 206 тьям № 1, 2012 comparative advantages and failures of decision variants available for antitrust bodies; ways of decision-making in expected merger. Also there are issues on efficacy of antimonopoly body decisions taking into account cost of monitoring, sanctioning of mergers participants, including influence on competition condition on relevant markets.
Telehealth systems demand standardized solutions to be cost effective and to take advantage of middleware operation and interoperability. The plug-&-play and standard-based platform that, either as individual elements or as components, can be incorporated in a simple way into different homecare environments. Many company, not traditionally involved in medical markets, increasing pressure for a standard for Personal Health Devices (PHD). As a result: ISO/IEEE11073 (X73) standards is adapting from Intensive Unit Care (ICU) scope, focused on the Point-Of-Care (PoC), to Personal Health Devices (PHD), focused on ubiquitous environments, implementing high quality sensors, supporting wireless technologies and providing a faster and more reliable communication network resources. This X73-PHD version is for the homecare challenge and might appear the best-positioned international standards to reach this goal. In this article, a X73 compliant agent and manager communication for homecare platform, as a proof of concept, will be explaining all steps implemented as well as on demand agent specific protocol plugins downloaded to X73 Manager.
The notion that certain management practices at all levels create substantial competitive advantages for the company in the market received a lot of attention in the academic community over the years. A large body of work was accumulated as a result, though it appears that a comprehensive understanding of the relationship between management practices and firm performance is still lacking. This study is a part of a larger project aiming at closing this gap. The objective of this study was to create a typology of companies based on efficiency, using a number of objective criteria obtained from publicly available information.
The monograph concerned on the organizational problems of monitoring programs of innovative development at the biggest Russian companies. In the book there is an original methodical approach to managerial accounting, analysis and control of the progress and results of innovation at enterprises. Conception underlines features and level of development of corporate management technology and specific holding structures. Monitoring is considered as a function of strategic control in a large enterprise in the process of innovation.
We consider a model of an on-line software market, where an intermediary distributes products from sellers to buyers. When products of sellers are vertically differentiated, an intermediary, earning a proportion of sales, has an incentive to hide the worse product on the second page, and only keep the better product on the front page: that weakens the competition, allowing the seller with the better product to charge a higher price. With heterogeneous visiting costs to the second page, the platform's revenue might improve, but the outcome will become socially suboptimal.
This book constitutes the refereed proceedings of the 7th International Workshop on Multiple Access Communications, MACOM 2014, held in Halmstad, Sweden, in August 2014. The 12 full papers presented were carefully reviewed and selected from 22 submissions. They describe the latest advancements in the field of multiple access communications with an emphasis on reliability issues, physical layer techniques, cognitive radio, medium access control protocols, and video coding.
A model for organizing cargo transportation between two node stations connected by a railway line which contains a certain number of intermediate stations is considered. The movement of cargo is in one direction. Such a situation may occur, for example, if one of the node stations is located in a region which produce raw material for manufacturing industry located in another region, and there is another node station. The organization of freight traﬃc is performed by means of a number of technologies. These technologies determine the rules for taking on cargo at the initial node station, the rules of interaction between neighboring stations, as well as the rule of distribution of cargo to the ﬁnal node stations. The process of cargo transportation is followed by the set rule of control. For such a model, one must determine possible modes of cargo transportation and describe their properties. This model is described by a ﬁnite-dimensional system of diﬀerential equations with nonlocal linear restrictions. The class of the solution satisfying nonlocal linear restrictions is extremely narrow. It results in the need for the “correct” extension of solutions of a system of diﬀerential equations to a class of quasi-solutions having the distinctive feature of gaps in a countable number of points. It was possible numerically using the Runge–Kutta method of the fourth order to build these quasi-solutions and determine their rate of growth. Let us note that in the technical plan the main complexity consisted in obtaining quasi-solutions satisfying the nonlocal linear restrictions. Furthermore, we investigated the dependence of quasi-solutions and, in particular, sizes of gaps (jumps) of solutions on a number of parameters of the model characterizing a rule of control, technologies for transportation of cargo and intensity of giving of cargo on a node station.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
The geographic information system (GIS) is based on the first and only Russian Imperial Census of 1897 and the First All-Union Census of the Soviet Union of 1926. The GIS features vector data (shapefiles) of allprovinces of the two states. For the 1897 census, there is information about linguistic, religious, and social estate groups. The part based on the 1926 census features nationality. Both shapefiles include information on gender, rural and urban population. The GIS allows for producing any necessary maps for individual studies of the period which require the administrative boundaries and demographic information.
Existing approaches suggest that IT strategy should be a reflection of business strategy. However, actually organisations do not often follow business strategy even if it is formally declared. In these conditions, IT strategy can be viewed not as a plan, but as an organisational shared view on the role of information systems. This approach generally reflects only a top-down perspective of IT strategy. So, it can be supplemented by a strategic behaviour pattern (i.e., more or less standard response to a changes that is formed as result of previous experience) to implement bottom-up approach. Two components that can help to establish effective reaction regarding new initiatives in IT are proposed here: model of IT-related decision making, and efficiency measurement metric to estimate maturity of business processes and appropriate IT. Usage of proposed tools is demonstrated in practical cases.
