A distributed system based on Fuzzy sets to select the optimal sizes of Unity Gain Cells (UGCs) is introduced. A zoom technique is also introduced to search for the optimal sizes in a more refined way. The selected sizes accomplish target specifications established by linguistic variables, namely gain “closer to” unity and “large” bandwidth, which are represented by fuzzy sets. The case of study is focused on three Voltage Follower and a CFOA whose performance characteristics are evaluated by using IC technology of 0.35µm and 180µm, respectively, and the circuit simulation program SPICE. Every circuit is codified by the width and large (W/L) of every Metal-Oxide-Semiconductor Field-Effect-Transistor (MOSFET) and by its bias current source. From the population of feasible solutions computed by evolutionary algorithms, the optimal W/L sizes are selected by the proposed distributed system through the intersection of fuzzy sets.

The relevance of the study under consideration is due to the need to increase the efficiency of students independent work in solving computational problems. A theoretical rationale is proposed and the practical implementation of an automated training and diagnostic system for the formation of skills to solve problems according to the “white box” model is described. The leading idea of the study is the construction of mental schemes for a given topic, which allow to visualize the dynamics of changes in the learner’s level of ability to solve computational problems. The methods of accounting for forgetting educational information and methods of personalized selection of tasks are substantiated. The site for self-management of user independent work is available at the link: http://msbx.ru. The materials of the article are of practical value for teachers who use e-learning tools in the educational process.

Abstract A “black box” model is described for simulating the dynamic forces transmitted to the vehicle hub by a tire running over an obstacle at high speeds. The tire is reduced to a damped one-degree-of-freedom oscillating system. The five parameters required can be obtained from a test at a given speed. The model input is composed of a series of empirical relationships between the obstacle dimensions and the displacement of the oscillating system. These relationships can be derived from a small number of static tests or by means of static models of the tire itself. The model can constitute the first part of a broader model for description of the tire and vehicle suspension system, as well as indicating the influence of tire parameters on dynamic behavior at low and medium frequencies (0–150 Hz).

For twenty decades, there is a visible ever forward advancement in the technology of mobility, vehicles and transportation system in general. However, there is no "cure-all" remedy ideal enough to solve all life problems but mathematics has proven that if the problem can be determined, it is most likely solvable. New methods and applications will keep coming to making sure that life problems will be solved faster and easier. This study is to adopt a mathematical transportation problem in the Coca-Cola company aiming to help the logistics department manager of the Asejire and Ikeja plant to decide on how to distribute demand by the customers and at the same time, minimize the cost of transportation. Here, different algorithms are used and compared to generate an optimal solution, namely; North West Corner Method (NWC), Least Cost Method (LCM) and Vogel’s Approximation Method (VAM). The transportation model type in this work is the Linear Programming as the problems are represented in tables and results are compared with the result obtained on Maple 18 software. The study shows various ways in which the initial basic feasible solutions to the problem can be obtained where the best method that saves the highest percentage of transportation cost with for this problem is the NWC. The NWC produces the optimal transportation cost which is 517,040 units.

Today, regional integration and globalization have added new dimensions to the problems of violence, religious extremism and terrorism that attract a lot of attention in the academic community of many counties. A polyconfessional and polyethnic state, Kazakhstan, where various trends of world religions are inevitably present, is especially aware of the problem of religious extremism. In these conditions, interconfessional relations as a guarantor of internal and external stability in our republic is one of its most important problems. This article presents the aspects related to the religious environment and threats of religious extremism in Kazakhstan and outlines feasible solutions.
