OPTIMIZATION OF PARAMETERS OF ELEMENTS COMPUTER SYSTEM
DescriptionThe work is devoted to the topical issue of increasing the productivity of computers. It has an experimental character. Therefore, the description of a number of the carried-out tests and the analysis of their results is offered. Previously basic characteristics of modules of the computer for the regular mode of functioning are provided in the article. Further the technique of regulating their parameters in the course of experiment is described. Thus the special attention is paid to observing the necessary thermal mode in order to avoid an undesirable overheat of the central processor. Also, operability of system in the conditions of the increased energy consumption is checked. The most responsible moment thus is regulating the central processor. As a result of the test its optimum tension, frequency and delays of data reading from memory are found. The analysis of stability of characteristics of the RAM, in particular, a condition of its tires in the course of experiment is made. As the executed tests took place within the standard range of characteristics of modules, and, therefore, the margin of safety put in the computer and capacity of system wasn't used, further experiments were made at extreme dispersal in the conditions of air cooling. The received results are also given in the offered article

OPTIMIZATION OF WELL PLACEMENT IN WATERFLOOD PROJECT IN "X" FIELD NIGER DELTA, NIGERIA
DescriptionWater flooding used in secondary oil recovery to level up reservoir pressure can be enhanced in order to fit the reservoir conditions with the aim to optimally recover oil. One of the important optimization variables to realize this aim is optimal well placement. Various methods have been suggested for this problem. Among these is direct optimization, although accurate, is difficult due to the number of simulations required. Optimal placement of up to six injection wells was studied at the X field in western Niger Delta of Nigeria. Injection rate and injection time was also optimized and net present value (NPV) of the flooding project was used as the objective function. In this case study, it is shown theoretically and by means of Eclipse 100 that according to the basic elementary reservoir characteristics, optimal oil recovery is strongly dependent on well placement pattern and injection rate. Simulation results show that good sweep efficiency can be achieved with a regular pattern with an optimal well position

Description
The article deals with studying the ways of optimizing the amount of chemical additives in the wood-concrete material, i.e. arbolite, which contains foamed polystyrene gravel aggregate. To make arbolite honeycombed structure more conglomerated a nonreactive aggregate, i.e. hogged chips, has been partially replaced with foamed polystyrene gravel aggregate which has a mean particle size equal to a concrete pocket size. The article also deals with various additives to be used, taking into account the nonreactive aggregate type and its quality, the composite density and its reinforcement level. All chemical additives have been chosen to make the initial material more porous, to produce a film covering the aggregate surface and to speed up the process of concrete hardening. To solve to above problems a series of experiments was carried out, the latter studied various combinations of factors changing at certain levels. The results of studying the foamed polystyrene gravel aggregate influence on the arbolite structure and its characteristics were used to make a choice of the arbolite composition. The main criterion of the optimal amount of chemical additives has been considered the arbolite strength. The experimental data processing has resulted in the finite regression model which describes the chemical additive amount influence on the arbolite strength. The tables in the article show the levels of technological factors varying and the matrix of planning the experiments to be carried out in order to optimize the chemical additive amount. As a result of the research accomplished the optimal amount of chemical additives has been determined which enables to produce the arbolite with some foamed polystyrene gravel aggregate in its composition
