An Interactive Web-based Application as Educational Tool for SCM Course by Using FOSS

This paper presents the application of free/open source software (FOSS) for teaching and learning one specific topic in Supply Chain Management (SCM) course. In the last few years, there is abundant FOSS for educational tools. However, educator still faces problems to implement such an education FOSS for improving the quality of education i.e. customizing of software function, developing of a specific educational media, and illustrating of a course content. The purpose of this research is to design an educational tool for increasing efficiency in conveying subject matter especially distribution problem. It has a module of real distribution problem in commodity paddy was captured. We crated an interactive Web-based application by using WSDL, PHP and My SQL, and SOAP. The result of the research will be able to improve the pedagogic approach for learning of SCM course. Keywords: Educational tool, FOSS, interactive media, SCM course

Educational Technology Topic Guide

This guide aims to contribute to what we know about the relationship between educational technology (edtech) and educational outcomes by addressing the following overarching question: What is the evidence that the use of edtech, by teachers or students, impacts teaching and learning practices, or learning outcomes? It also offers recommendations to support advisors to strengthen the design, implementation and evaluation of programmes that use edtech. We define edtech as the use of digital or electronic technologies and materials to support teaching and learning. Recognising that technology alone does not enhance learning, evaluations must also consider how programmes are designed and implemented, how teachers are supported, how communities are developed and how outcomes are measured (see http://tel.ac.uk/about-3/, 2014). Effective edtech programmes are characterised by: a clear and specific curriculum focus the use of relevant curriculum materials a focus on teacher development and pedagogy evaluation mechanisms that go beyond outputs. These findings come from a wide range of technology use including: interactive radio instruction (IRI) classroom audio or video resources accessed via teachers’ mobile phones student tablets and eReaders computer-assisted learning (CAL) to supplement classroom teaching. However, there are also examples of large-scale investment in edtech – particularly computers for student use – that produce limited educational outcomes. We need to know more about: how to support teachers to develop appropriate, relevant practices using edtech how such practices are enacted in schools, and what factors contribute to or mitigate against successful outcomes. Recommendations: 1. Edtech programmes should focus on enabling educational change, not delivering technology. In doing so, programmes should provide adequate support for teachers and aim to capture changes in teaching practice and learning outcomes in evaluation. 2. Advisors should support proposals that further develop successful practices or that address gaps in evidence and understanding. 3. Advisors should discourage proposals that have an emphasis on technology over education, weak programmatic support or poor evaluation. 4. In design and evaluation, value-for-money metrics and cost-effectiveness analyses should be carried out

Teaching, Analyzing, Designing and Interactively Simulating of Sliding Mode Control

This paper introduces an interactive methodology to analize, design, and simulate sliding model controllers for R2 linear systems. This paper reviews sliding mode basic concepts and design methodologies and describes an interactive tool which has been developed to support teaching in this field. The tool helps students by generating a nice graphical and interactive display of most relevant concepts. This fact can be used so that students build their own intuition about the role of different parameters in a sliding mode controller. Described application has been coded with Sysquake using an event-driven solver technique. The Sysquake allows using precise integration methods in real time and handling interactivity in a simple manner.Peer ReviewedPostprint (published version

An adaptive e-Learning platform based on IP multicast technology

Comunicação apresentada na International Conference on Information and Communication Technologies in Education, Badajoz, 2002.A wide range of applications involving different types of media, with distinct quality of service and network resources requirements have been fostering the computer communications community in order to improve the service provided by the Internet. Besides the IETF recent proposals for introducing QoS in the Internet, multicast technology proposed by S.Deering assumes a major role in supporting group-oriented applications. This article describes the design, implementation and operation of an adaptive distance learning system based on IP multicast technology accessible through a Web browser. This system uses public domain multimedia multicast to build a system which adapts conveniently to the available network resources and to the hardware capabilities of the end-system. The system architecture includes an adaptive module based on Java applets and embedded Javascript, responsible for assessing the existing operating conditions, by collecting the client's system performance (e-student's host) and relevant group characteristics. The collected data is subsequently computed weighting parameters, such as the available bandwidth at the client side, the round-trip time between the client and the remote server, the client's current CPU load and free memory. The obtained result is used for proper multicast applications scheduling and parameterisation in a transparent way

DEVELOPMENT OF VIDEO CONFERENCE USING JMF

Video Conferencing is well-planned to offer high quality ofreal time video and audio transmission. Video Conferencing has added extra flavors to students and lecturers interaction inUTP by having stable communication channel via real time video. Live feed from the media file and captured video can bebroadcasted through the thousand ofuniversity's population innetwork by concentrating in reserving the quality ofthe video while at the same time reducing the cost of bandwidth. It's always great compromise in maintaining the quality ofvideo with the cost bandwidth. Here it goes the need of good compression technique as compression will cause the data to lose some of the information and degrade the quality. The tolerable degradation is always at the author's spotlight. The student has undergone 3 significant phases of system development which are Analysis, Design, and Coding. The critical function ofJava Video Conferencing has been successfully implemented. Open the media file, capture the real time video, transmit the file, transmit the real time captured video, open the file in another computer, broadcast to the network attached computers and view the real time broadcasted video in the network attached computers. Communicating in text mode is an added feature in the Video Conferencing. This Video Conferencing has a room for improvement in achieving the best interaction mode in Information Communication Award. Video Conferencing is seen to have a bright future in realizing the need of Virtual Learning in UTP

Event Based Retrieval From Digital Libraries Containing Data Streams

The objective of this research is to study the issues involved in building a digital library that contains data streams and allows event-based retrieval. “Digital Libraries are storehouses of information available through the Internet that provide ways to collect, store, and organize data and make it accessible for search, retrieval, and processing” [29]. Data streams are sources of information for applications such as news-on-demand, weather services, and scientific research, to name a few. A data stream is a sequence of data units produced over a period of time. Examples of data streams are video streams, audio stream, and sensor readings. Saving data streams in digital libraries is advantageous because of the services provided by digital libraries such as archiving, preservation, administration, and access control. Events are noteworthy occurrences that happen during data streams. Events are easier to remember than specific time instances at which they occur; hence using them for retrieval is more commensurate with human behavior and can be more efficient via direct accessing instead of scanning. The focus of this research is not only on storing data streams in a digital library and using event-based retrieval, but also on relating streams and playing them back at the same time, possibly in a synchronized manner, to facilitate better understanding in research or other working situations. Our approach for this research starts by considering digital libraries for: stock market, news streams, census bureau statistics, weather, sports games, and the educational environment. For each of these applications, we form categories of possible users and the basic requirements for each of them. As a result, we identify a list of design goals that we take into consideration in developing the architecture of the library. To illustrate and validate our approach we implement a medical digital library containing actual Computed Tomography (CT) scan streams. It also contains sample medical text and audio streams to show the heterogeneity of the library. Streams are displayed in a concise, yet complete, way that makes it unproblematic for users to decide whether or not to playback a stream and to set playback options. The playback interface itself is organized in a way that accommodates synchronous and asynchronous streams and enables users to control the playback of these streams. We study the performance of the specialized search and retrieval processes in comparison to traditional search and retrieval processes. We conclude with a discussion on how to adapt the library to additional stream types in addition to suggesting other future efforts in this area

Ontology-based personalized job recommendation framework for migrants and refugees

Participation in the labor market is seen as the most important factor favoring long-term integration of migrants and refugees into society. This paper describes the job recommendation framework of the Integration of Migrants MatchER SErvice (IMMERSE). The proposed framework acts as a matching tool that enables the contexts of individual migrants and refugees, including their expectations, languages, educational background, previous job experience and skills, to be captured in the ontology and facilitate their matching with the job opportunities available in their host country. Profile information and job listings are processed in real time in the back-end, and matches are revealed in the front-end. Moreover, the matching tool considers the activity of the users on the platform to provide recommendations based on the similarity among existing jobs that they already showed interest in and new jobs posted on the platform. Finally, the framework takes into account the location of the users to rank the results and only shows the most relevant location-based recommendation

MediateSpace: applying contextual mediation to the tuple space paradigm

I designed, implemented and evaluated a decentralised context-aware content distribution middleware. It can support a variety of applications, with all network communication handled transparently behind a tuple space based interface. Content is inserted into the network with an associated condition stipulating the context that must be matched to receive it. Conditions can be expressed using conjunctions, disjunctions, a form of universal and existential quantification and nested block scopes. Conditions are mapped onto a set of spatial indexes to enable lookup; and these are inserted into a distributed multi-dimensional spatial data structure (e.g. an R-Tree). They are also translated into an OWL representation to enable evaluation. Nodes bind to their most geographically proximate neighbours which allows distance-sensitive context sharing. The middleware is capability-aware, pushing computationally expensive tasks onto more capable nodes. I evaluated my system through benchmarks and simulation, defining condition classes which collectively represent a large portion of the condition space. Random conditions were generated from these classes. Node mobility was controlled through a number of probability distributions. Benchmark evaluation times were reasonable, evaluating 500 typical messages in 1.4 seconds each. When the number of stored contexts were reduced, this improved dramatically, evaluating 500 much more complicated conditions in one-tenth of a second each. The number and complexity of context parameters has a major impact on efficiency. The number of spatial indexes generated was reasonable for most conditions, with a 95th percentile of 6. However, existential quantification was a challenge for both condition evaluation and index generation due to the potentially large number of possible combinations of conditions. As expected, simulations found that the distribution of workload was very uneven because nodes tend to cluster in large cities; meaning that most communication is localised within these areas. Also, node density had a dramatic impact on the number of received messages as nodes within sparse areas were unable to obtain context information which precluded condition evaluation. I achieved my research goals of developing a distributed context-aware content distribution framework
