Mobile technologies called ViSCoS where one can study the first year Computer have also potential to introduce totally new ways to support Science studies through the Internet.

The purpose of this paper is not to evaluate or test expanding the current PC-based solution towards mobile devices already existing solutions, but to elaborate and discuss the has been given a name ViSCoS Mobile. We discuss the possibilities and challenges of the ViSCoS Mobile concept. We possibilities and problems related to the design of the ViSCoS also analyze the first potential solutions for implementing the Mobile and propose preliminary solutions to them.

The curriculum of ViSCoS consists mobileBlogs. The limited capabilities of the mobile devices are a of three main areas – the preliminaries of ICT, basics of major obstacle, but we argue that with a proper tool development programming with Java, and an introduction to computer science this issue can be overcome. [7]. ViSCoS courses require about 600 hours of work (equals to 25 credit points in the European Credit Transfer System). The Keywords courses are given within three half-year semesters: the aim is to Mobile learning, mobile devices, distance education, content finish the studies in one and a half years time [18]. Table 1 shows adaptation. the content of the ViSCoS courses. 1. INTRODUCTION Table 1. Courses in ViSCoS.

In an ideal situation, learners could use whatever device to conduct learning activities. With a mobile device, students could, for instance, ViSCoS studies started in September 2000. At first, ViSCoS was carry their study notes everywhere. offered solely to high school students in the surrounding area of Joensuu, and it was open and free for anyone who was interested. 143 Later, the program has expanded to other parts of Finland.

Content adaptation would support the Table 2 shows the number of students starting and graduating in portability of the ViSCoS studies, because students could use ViSCoS between years 2000-2005.

This would enable more versatile ways to program with marks high enough (grade 2 out of 3), they are free study the courses. to enter the organizing university as computer science majors.

Especially young researchers are encouraged to join all IBS events. The series IBS Scientific Workshop Proceedings (IBS-SWP) publishes peer reviewed papers contributed to IBS - Workshops. IBS-SWP are open access publications, i.e. all volumes are online available at IBS website www.ibs-laubuch.de/ibs-swp and free of charge. IBS Scientific Workshop Proceedings aim at the ensuring of permanent visibility and access to the research results presented during the events staged by Foundation IBS. Preface Annual summer school was organized successful in this year from 29th June to 1th July in Laubusch, Germany. In this summer school attended bachelor, master and doctors students, researchers from Mongolia, Germany, Russia, India and Turkey. Topics of SS2015 were: e-learning, embedded systems and international cooperation between universities of partner countries. One of the highlighted points of this year was attendance of bachelor students from Mongolia and video session with Russian delegation. Master students from India and Turkey presented own ongoing research and got live feedback from researchers and professors. Next highlight of summer school was formal agreement with extension of Summer School in next year by Harbin Technical University, China. By idea of Russian university summer school will be change places from year to year by partner university countries. One of the main goals of this international event is to give opportunity to students and researchers of partner universities to work together during school time actively and freely in frame if science and international cooperation.

    Master's thesis Two years International Master’s Degree in Computer Engineering Cross-Platform Solution for Mobile Application Development MA level, 30credits Aditya Polisetti Cross-Platform Solution for Mobile Application Development Abstract Aditya Polisetti 2014-11-10 Abstract With the possibility to increase the smart phone market, the mobile application development is experiencing a rapid improvement in terms of both revenue and innovation. Considering the demand in the applica- tion development market, there is an urge to develop applications faster and smoother with the growing number of different platforms and technologies. Many companies and brands are making their marketing strategies more efficient by using mobile applications. The constant growth in mobile devices and operating systems raise several problems and challenges in mobile application development. With this growth, a developer finds it difficult to build applications keeping the native technologies in mind with respect to the device platform. Application development for a mobile device mainly deals with native development platforms such as C, Objective-C, Java, C#, J2ME, C++ etc., and is incompatible with the cross-platform support. HTML5 is a solution that incorporates cross-platform capability in all these devices. The purpose of this thesis is to research the different approaches of mobile application development and to find a favourable environment for a cross mobile platform development. The smart phone application development can built in three environments and the applications can differ such as native applications, cross-platform applications and hy- brid applications. The research work includes the study of several cross-platform frame- works, responsive web designing and location-based web services.

  • Acquisition of Hypernyms and Hyponyms from the WWW
    Acquisition of Hypernyms and Hyponyms from the WWW Ratanachai Sombatsrisomboon *1 Yutaka Matsuo *2 Mitsuru Ishizuka *1 *1 Department of Information and Communication Engineering *2 National Institute of Advanced Industrial Science School of Information Science and Technology and Technology (AIST) University of Tokyo [email protected] Abstract. Recently research in automatic ontology construction has become a hot topic, because of the vision that ontology will be the core component to realize the semantic web. This paper presents a method to automatically construct ontology by mining the web. We introduce an algorithm to automatically acquire hypernyms and hyponyms for any given lexical term using search engine and natural language processing techniques. First, query phrase is constructed using the frame “X is a/an Y”. Then corpora sentences is obtained from the result from search engine. Natural language processing techniques is then employed to discover hypernym/hyponym lexical terms. The methodologies proposed here in this paper can be used to automatically augment natural language ontology, such as WordNet, domain specific knowledge. 1. Introduction Recently research in ontology has been given a lot of attention, because of the vision that ontology will be the core component to realize the next generation of the web, Semantic Web [1]. For example, natural language ontology (NLO), like WordNet [2], will be used to as background knowledge for a machine; domain ontology will be needed as specific knowledge about a domain when particular domain comes into discussion, and so on. However, the task of ontology engineering has been very troublesome and time -consuming as it needs domain expert to manually define the domain’s conceptualization, left alone maintaining and updating ontologies.
