Development tools for mobile devices in market price information systems

There are already several applications on mobile devices that can be useful in agriculture. For example: GPS-enabled map software, individual cattle identification and tracking software and even complex agricultural systems. These are just beginning to spread in the Hungarian agrifood sector. The possibility of using for agribusiness of mobile internet and mobile tools is increasing. Mobile tools are really suitable for tasks like inspecting the evolution of prices of agricultural products. One of our application development is a mobile extension to access the Market Price Information System run by the Hungarian Agricultural Economics Research Institute. The accessibility of information demanded by market actors can be ensured effectively by using mobile tools. The biggest limitation for PDA is screen size. If it is getting smaller from full screen to PDA-sized and yet further to mobile phone dimensions, user performance drops. The main reason for this is that smaller screens make it more difficult for a user to make good judgements about the usefulness of any particular information. The development methods and tools help us to solve one part of these problems

Understanding new ways of learning in the 21st century: A preliminary study into mobile technologies

In this paper, we describe a theoretical framework and design of a study of mobile technologies in a first year university course, where students use mobile phones, or smartphones as cognitive tools. The paper describes a broader study into the use of mobile technologies with authentic learning environments, and then outlines a plan for an investigation into the nature of use of the devices in the completion of an authentic task

Generating Multimedia Components for M-Learning

The paper proposes a solution to generate template based multimedia components for instruction and learning available both for computer based applications and for mobile devices. The field of research is situated at the intersection of computer science, mobile tools and e-learning and is generically named mobile learning or M-learning. The research goal is to provide access to computer based training resources from any location and to adapt the training content to the specific features of mobile devices, communication environment, users' preferences and users' knowledge. To become important tools in education field, the technical solutions proposed will follow to use the potential of mobile devices.M-learning, mobile devices, MPEG-21 standard, multimedia databases

Mobile device forensics: a snapshot

In the increasingly dynamic environment of mobile forensics, this paper provides an overview of the capabilities of three popular mobile forensic tools on three mobile phones based on Apple’s iOS, Google’s Android and RIM’s BlackBerry operating systems. The paper identifies where each specific tool is best applied and also describes the limitations of each in accessing contacts, call history, message data (SMS, MMS and emails), media files and other data. New releases of forensic tools and mobile operating systems may change the way the data are acquired and preserved in the future. It is therefore hoped that future research will continue to provide the digital forensics community with the most up-to-date overview of mobile forensics capabilities

A characterisation of reliability tools for Software Defined Networks

Software Defined Network (SDN) is a new paradigm in networking that introduces great flexibility, allowing the dynamic configuration of parts of the network through centralised programming. SDN has been successfully applied in field networks, and is now being applied to wireless and mobile networks, generating Software Defined Mobile/Wireless networks (SDWNs). SDN can be also combined with Network Function Virtualization (NFV) producing a software network in which the specific hardware is replaced by general purpose computing equipment running SDN and NFV software solutions. This highly programmable and flexible network introduces many challenges from the point of view of reliability (or robustness), and operators need to ensure the same level of confidence as in previous, less flexible deployments. This paper provides a first study of the current tools used to analyse the reliability of SDNs before deployment and/or during the exploitation of the network. Most of these tools offer some kind of automatic verification, supported by algorithms based on formal methods, but they do not differentiate between fixed and mobile/wireless networks. In the paper we provide a number of classifications of the tools to make this selection easier for potential users, and we also identify promising research areas where more effort needs to be made.Universidad de Málaga.

RCSB PDB Mobile: iOS and Android mobile apps to provide data access and visualization to the RCSB Protein Data Bank.

SummaryThe Research Collaboratory for Structural Bioinformatics Protein Data Bank (RCSB PDB) resource provides tools for query, analysis and visualization of the 3D structures in the PDB archive. As the mobile Web is starting to surpass desktop and laptop usage, scientists and educators are beginning to integrate mobile devices into their research and teaching. In response, we have developed the RCSB PDB Mobile app for the iOS and Android mobile platforms to enable fast and convenient access to RCSB PDB data and services. Using the app, users from the general public to expert researchers can quickly search and visualize biomolecules, and add personal annotations via the RCSB PDB's integrated MyPDB service.Availability and implementationRCSB PDB Mobile is freely available from the Apple App Store and Google Play (http://www.rcsb.org)
