In this paper, firstly, a decoupled sliding mode controller (DSMC) is designed for stabilization of an inverted pendulum system. Secondly, a multi-objective particle swarm optimization (MOPSO) algorithm is implemented to optimize the DSMC parameters in order to decrease the normalized angle error of the pole and normalized distance error of the cart, simultaneously. The proposed Pareto front for the DSMC problem is validated through comparisons with existing state-of-the-art multi-objective algorithms. Then, java programming with applets is presented in order to simulate the stability and educate the internet-based control. (C) 2012 Elsevier Ltd. All rights reserved.

Women safety is of major concern. The crime rates against women are increasing at an alarming rate and thus it is important to ensure their safety whether at home or at the workplaces. Many necessaries measures have been taken to ensure women safety. Despite many measure taken to protect women, there are still high number of crimes against them. In this research, a mobile based application is proposed that will help user to reach the relevant authorities during emergency situations in real time. The mobile application provides users with the fastest and simplest way to contact the nearest authorities by doing a few gestures on their smartphone. This application sends SMS to the emergency contacts number that has been registered in the phone contact, track one's location in real-time via GPS monitoring which uses MapBox as its primary source. programming language that is java and Firebase for the database are the technologies chosen to develop this application This application also can trigger alert sound by constant shaking of the phone to alert public once the victims encounter possible attackers. These features are for both everyday safety and real emergencies, making it an ultimate tool for all. With this application, victim not only can alert people in close proximity of their situations but get immediate help and action to prevent unwanted incidents from happening.

Mutation testing is a technique that changes code instructions to assess the quality of automated software tests. Industry has not broadly adopted the technique because execution and analysis times are too long and not considered worth the effort. To change this, a variation called "extreme mutation testing" emerged, which mutates whole methods instead of instructions. The extreme variant trades accuracy for speed gains and also provides pre-analyzed results. In this study, we aim to analyze both techniques on their granularity levels, look for benefits when combining them, and find motivations when a developer considers killing mutants. For that, we conducted a case study in a company from the semiconductor industry. We mutated a large java software project which is tested by more than 11,000 unit tests, analyzed the results, manually inspected more than 1000 mutants, and conducted a focus group with five developers of the software. Among other results, we provide the distribution of traditional across extreme mutants as well as qualitative coding results of our mutant inspection and focus group transcript. We conclude that the traditional approach can be similarly strategically applied as the extreme one and that motivations of developers to target mutants are mostly not code related.

Determining input impedance, assigning reflection coefficient, and matching load impedance are important transmission line problems those involve complex calculation steps because of complex connection architectures in transmission lines. Efficient understanding of such problems in undergraduate and graduate courses should be supported by rich visualization tools. The Smith chart is a convenient tool for transmission line calculations especially for wave propagation and maximum power theory that discusses impedance matching problems. In this context, we can say that java is a widely used open source educational tool having strong computational environment for research and development aims. In this study, an open source transmission line impedance matching educational framework (TLIME) has been designed to teach efficiently wave propagation and maximum power theory that discusses the impedance matching problems. The success of developed educational framework has been measured by a questionnaire held in courses in the third and fourth years of the electrical and electronics engineering undergraduate program at Sakarya University of Applied Sciences, Turkey. The visual preparation of the problem solutions with rich graphical user interface and simulations of the mathematical representations has been evaluated to contribute to a better understanding of the wave propagation and impedance matching transmission line subjects. The functionality and simplicity of the developed framework scored by over 82% among course enrolled students. The rest of the paper is organized as follows. Section 2 explains transmission line impedance matching problem in the context of maximum power theory. Section 3 discusses transmission line planning and problem solving with Smith chart. Section 4 discusses explanation and usage of developed TLIME framework and last section discusses results.

Brief overview of the Serbian IT sector employment situation is given. Through the summary of the past online learning experiences it is shown that online learning can be an effective tool to reeducate the Serbian workforce to serve the countries growing IT employment demands. The nature of the UN Development grants in Serbia is explained together with the details of the joint proposal from the University of San Diego Extension and the Mathematical Institute of the Serbian Academy of Sciences and Arts. The proposal consisted of a group of java and Python courses that were delivered online in English to 34 students selected from more than 80 people that applied. The results presented show that the program was very effective with an extremely high satisfaction rate both in terms of the content and online delivery platform, and that the similar methods can be used in the future for further education of the IT workforce.

programming is a skill of the future. However, decades of experience and research had indicated that the teaching and learning of programming are full of problems and challenges. As such educators and researchers are always on the look-out for suitable approaches and paradigms that can be adopted for the teaching and learning of programming. In this article, it is proposed that a visual output approach is suitable based on the current millennials affinities for graphics and visuals. The proposed Vjava Module is developed via the application of two main learning theories, which are, the cognitive load theory and constructivism. There are two submodules which consist of eight chapters that cover the topics Introduction to programming and java, Object Using Turtle Graphics, Input and Output, Repetition Structure, Selection Structure, More Repetition Structures, Nested Loops and Arrays. To enable java programs to produce graphical and animated outputs, the Mjava library was developed and integrated into this module. The module is validated by three java programming experts and an instructional design expert on the module content, design and usability aspects.

Mobile technology evolution and mobile based education are highly needed for academic system. Especially designing a physical antenna is a tough task so that Simulation solution has been used in the laboratory. Even though it is costlier and it could be used only in LAN based computers for an academic purpose but not used in outside. To be clear, the designing of an antenna with institution studies are needed. To overcome and achieve the objective of the paper which proposes to develop a mobile based designing antennas such as Dipole, Loop antennas. The performances of antenna have been carried out in mobile platform. This is an attempt to predict parameters of specified antenna in the android platform. Through this application the students could able to predetermine the characteristic of specified antenna easily. This application will be highly useful and recommended to the students. The proposed work has been designed by Eclipse software and Android studio software. Finally the performance of the antenna parameters has been carried with the help of Android-Antenna Tool (AAT).
