Experimental analysis based on optical model and electromagnetic properties of multilayer absorbers

This research aims to contribute with the design optimization of multilayer absorber material applicable in stealth technologies. This study involves a pre-analysis of the electromagnetic properties of five individual plates (absorbing layers), considering the reflection and transmission coefficients. From these characteristics was established the best combinations of the individual layers in sets of three layers. For this, five plates based on styrene-butadiene rubber (SBR) matrix loaded with carbon black (2-50 phr) were processed.

Analysis of women’s participation on Turkish publicly traded company boards

In 2012, Turkish Capital Markets Board of Turkey (CMBT) took the first step about increasing women’s participation on Turkish publicly traded company boards with a soft law. However, under the framework of the Corporate Governance Principles of CMBT, the regulation did not have the intended impact and had very limited application. In order to draw attention to the issue and extend the influence of the regulation, supportive projects were launched in Turkey.

Automatic questions generating system

All the educational information can be accessible through the Internet sites (e.g., Wikipedia, news administrations). Learning the information by searching through random website is difficult, one of the main difficulties is to frame the questions for famous people who have a Wikipedia page. Here, we address some portion of this test via mechanizing the formation of a particular kind of useful inquiries that can improve the learning background. In particular, we focused consequently producing true questions from the text or keywords provided.

Smart garbage monitoring system

Garbage bins are found at all the places in a particular collage, school, hospital, bank, shopping malls etc. Every time it is not possible to check whether the bin is full or empty, so in this paper we come up with a solution to monitor the status of every bin inside the campus area of any school, collage or any other place. Here we actually use arduino board connected to an ultrasonic sensor and a Wi-Fi module and this entire system is connected to every single bin inside the campus area.

The analysis of human development levels via multi-criteria decision making methods with different weighting techniques: the case of European Union members, candidates and potential candidates

The measurement of countries’ human development levels goes beyond measuring gross domestic product in recent years. There is not a general concern about the structural expression of human development. United Nations Programme makes researches to measure development with human development index (HDI) based upon the perspective of “enlarging people’s choices”. On the other side, European Union (EU) analysis how to measure human development in European context. There is ahuge necessity of alternative data and methods for the analysis.

Task scheduling algorithms for parallel processing

In computing, Scheduling refers to a set of policies which define the order of execution of processes. The scheduling for the processor is done to keep it as busy as possible. Parallel computing includes scheduling of multiple processors, and managing the resources for all the processors. The scheduling in multiprocessors is more difficult than scheduling in a single processor unit. In scheduling of multiple processors it should be ensured that any processor should not be overloaded and any processor should not be under loaded. So the overall system should be balanced.

Statistical estimation with gene frequencies in a b o blood group systems

Statistics is one of the major tools to study the quantitative aspects of Biological theories. In the literature about Biostatistics, many statisticians have applied basic biometric methods for medicinal applications where as a few statisticians have applied those for genetic applications. In the present study, an attempt has been made by estimating gene frequencies in ABO blood group system in human beings through the Maximum Likelihood method.

Land use mixing and urban infrastructure

Land use in urban areas are to date being regulated within the frame work of a development plan. One of the key components of the development plan is a proposed land use plan for a target year. Zoning is now a major tool for regulation of land use in urban area. Urban structure of the city is meant to provide facilities to the people. So, either the people go to the facilities or the facilities come to the people. The former part deals with zoning concept and zoning based urban structure is transport oriented.

Iot system security: challenges and prospective solutions

The increasing demand and use of IoT systems has no doubt made our lives very easy and comfortable. With day by day growth of technology, new kinds of attacks and threats are occurring each day. Therefore, it is necessary to ensure the security of our networks and data. This paper tries to look at a variety of security problems that can be faced in the IoT Systems and their prospective solutions given by various authors. In the end, a comparative study of the problems addressed and the solutions given in each of the paper is done.

Software configuration management techniques and principles

Software Configuration Management (or Software Change Management) is defined as the task of tracking and controlling changes in software. It is a part of a larger field of configuration management. It helps in identifying individual elements and configurations, tracking changes, and version selection, control, and baselining. Software products are very complex to develop and are even more difficult to maintain. There are various problems faced in SCM such as balancing the costs of productions with benefits from increased sales of software products.
