This paper is intended to present a trend analysis resulting from different secondary to primary windings ratio of evolutionary optimized audio transformer. Evolutionary optimization of audio transformers is a perspective approach to the wideband audio transformers design by employing methods of artificial intelligence algorithms. This novel approach to audio transformers designing has a notable implication for problematics related to audio transformers complex design process. The authors are building on their previous research by trying to determine the trends which can be observed by selecting different secondary to primary windings ratio of evolutionary designed audio transformer. These trends can be useful at further optimization of the designing algorithms. © 2013 Springer-Verlag.

This paper propose parallel implementation of Ant Colony System (ACS) algorithm for automated combinational circuit design. Ant Colony System is one of the most popular and widely used Ant Colony Optimization (ACO) algorithm and heuristic algorithm in general. As digital logic circuits become more complex, efficient circuit design is priority and use of heuristic methods are unavoidable. Unfortunately, the optimization problems became so complex in sense of their size, even the most powerful heuristic algorithms can't solve them on single CPU. In order to be able to tackle the problem, parallel version of ACS is needed and this paper presents CUDA (Compute Unified Device Architecture) C language implementation.

Interferences among enhanced local optical fields generated by a plasmonic metal-coated conical dielectric probe with a nano-rod are investigated numerically. The dark spots that are interference patterns among plasmon-enhanced local fields are investigated in detail. It is found that two kinds of interference patterns (dark spots) are created in the free space in the vicinity of the nano-rod. One is created near the rod-end and has a disk shape. The other is created around the nano-rod and has a toroidal shape. Both kinds of patterns have nanoscale dimensions, because they are generated by interference between near fields that have large wavenumbers.

The main purpose of this paper is to present a service called Teaching Assistant. The aim of the assistant is to facilitate the task and assessment management in collaborative learning scenarios. This assistant intends to help instructors to design and to evaluate collaborative learning tasks in this type of scenarios. For the development of the Teaching Assistant we defined an instructional model based on the Group Investigation method. The implementation of the assistant is embedded into the Learning Management System Moodle. Nowadays, a research study has been performing with students and instructors at the Universidad Pontificia Bolivariana, UPB-Montería (Colombia). The objective of the study is to identify the effect of the Teaching Assistant in the design process of the collaborative learning scenarios scripted by the instructors in Moodle. Specifically, how the assistant decreases the time used in this process. Due to this improvement, the learning experiences can be better. © 2013 Springer-Verlag Berlin Heidelberg.

This work investigated the effects of using a social media web application to assist learning and teaching in classrooms on learners' performance. We examined Facebook activities of 98 students, consisting of the groups of class of 4/1, 4/3 and 5/1 of Sa school located in Nan province, Thailand, during the first semester of 2011. We applied both statistics and data mining techniques for data analysis to determine the effects of Facebook usages for education on students' learning skills. Statistics was used to evaluate the correlation between students' Facebook usage and grade point averages, and a data mining technique was used to learn association rules from data. This project has helped us learn the effects of using social media web applications (i.e., Facebook applications) for education on student-learning performance. We found that examining the ratio of number of Facebook posts and comments for educational purposes to the one for non-educational purposes could help us draw a conclusion that Facebook usage does have an impact on students' learning performances. Specifically, we found that students who spent more time on education-related posting and commenting earned better grades than the ones who did the opposite. Furthermore, as we have to group data to change numerical data to nominal data, we found that data grouping play an important role on the number of rules and their associated confidence values. Too loose and too tight data grouping might be the reason the Association Rule algorithm derives few rules with high confidence values. We hope the results can help learners and teachers realize the advantages, disadvantages and effects of using social media web application for education.

A number of techniques have been recently proposed to implement molecular communication, a novel method which aims to implement communication networks at the nanoscale, known as nanonetworks. A common characteristic of these techniques is that their main resource consists of molecules, which are inherently discrete. This paper presents DIRECT, a novel networking model which differs from conventional models by the way of treating resources as discrete entities;therefore, it is particularly aimed to the analysis of molecular communication techniques. Resources can be involved in different tasks in a network, such as message encoding, they do not attenuate in physical terms and they are considered 100% reusable. The essential properties of DIRECT are explored and the key parameters are investigated throughout this paper. © 2013 Elsevier Ltd.

In this paper, we propose and implement a medical support system considering P2P and IoT technologies. We used our implemented smart device that we call Smart Box. We have implemented in the Smart Box many functions and sensor such as body sensor, infrared sensor, chair or bed vibration control, light control, smell control and sound control. By using Smart Box the implemented system is able to control the situation of patients. We carried out experiments to evaluate the implemented system. The evaluation results show that the implemented system can detect the patient situation.

Many countries, European and worldwide, have increasingly issued during the last decade electronically readable identity documents to their citizens, for different purposes and applications. However, a major characteristic of all these systems is that they are basically available in a national context. For example, European citizens that move freely through the Member-States face the problem that their eIDs from their home state do not allow access to services of another Member-State in which they are temporarily present. Public Administrations are also unable to provide services to European citizens from other Member-States with the same ease and efficiency as they do to their national citizens. In order to avoid such confusing situations, cross-border services should be fully integrated in the national/regional and local information systems. It is, therefore, an important task to improve the cross-border interoperability of electronic identification and authentication systems. ENISA, the European agency for the security of computer systems and networks, recently published a report dealing with an important aspect of this problem: the security issues in cross-border electronic authentication. The report assesses the risks of electronic authentication in cross-border solutions and provides a generic implementation model. This paper describes an implementation methodology for addressing the cross-border interoperability of electronic authentication problem, based on the ENISA generic model. The proposed implementation methodology has been based on the successful NETC@RDS project approach and experience, described herein. This methodology can provide a suitable secure cross-border, multi-purpose authentication implementation based on the aforementioned generic model that can be used in various sectors. © IFIP International Federation for Information Processing 2013.
