Building Location-based Service with Java Technologies

The growing use of Java in Location-based Service provides an opportunity to find solutions for problems and challenges in the rapidly changing telecommunications environment. This paper describes the development of location-based service components using Java technologies. The technologies include J2ME, Servlet, Java Server Pages (JSP) and XML Java Binding Tool. The developed components are the location server simulator, location service application and device client application. This study is crucial for support of BT’s launch of User Location Service on prototype ERICA mobile application platform through supporting the testing and validation of the platform components

Spectrophotometric estimation of nitro tyrosine by azo-coupling reaction

3-Nitrotyrosine has been identified using techniques like immunohistochemistry, HPLC, GCMS to demonstrate as a relevant biomarker in various disorders such as neurological, cardiovascular and others. Estimation of 3-NT by spectrophotometric method has been performed to measure 3-NT over decades. However none of the above methods have been translated to diagnose the diseases, but pathological conditions. Therefore here is an attempt to develop a method to be employed as a diagnostic tool. Current work is focussed on including preparation of 3-NT and further to derivatives using β-Napthol to yield diazotised product. All these intermediates of diazotized products have been characterized by ESI MS and the final colored dye was measured spectrophotometrically which exhibits λ max at 551 nm. The dye has been measured and compared with the direct measurement of 3-NT. The sensitivity of measurement of 3-NT increases by 10 fold, by and large we can estimate 20 μM concentration of 3-NT

A Context Gathering Framework for Context-Aware Mobile Solutions

One of the fundamental design issues in context-aware mobile services development is the necessary support for adequately powerful yet efficient querying of the sensory data. This issue argues for research into the creation of a technology-independent, high-level software application programming interface (API) that provides mechanisms for dealing with the heterogeneity of sensors providing raw context data. In this paper, we review approaches in existing context-aware platforms especially those that consider with sensory data acquisition. The review formed the basis for the design and development of the context gathering framework which consists of sensor data model, messaging and communication protocol and software application programming interface. These components form as one of the enabler to support the development of context aware mobile applications

MEDICT: A Malay<-> English Bilingual Dictionary For Java Mobile Phones

Today, mobile phones provide number of advanced functions, among which possibility of running mobile applications seems to be the most interesting feature. It changes a standard mobile phone into a mini-size yet still powerful computer that able to run various applications, for example games, stock checkup, map guide, dictionary and so on. This paper presents a project currently in progress which aims at the construction of bi-directional Malay - English translation dictionary named MEDict. MEDict is an easy-to-use mobile dictionary that is the ideal reference tool for all those requiring quick access to word translations. MEDict will ideally suit J2ME mobile phones with GPRS connectivity. This paper delivers the initial development progress of MEDict. It covers the functional requirements and possible development approaches followed in building MEDict. The project incorporates the development of four main components: (1) a java-based mobile client that provides interface for front-end query input; (2) a back-end database for serving dictionary contents; (3) a dictionary service for handling the exchange between the mobile client's queries and the database; (4) a web system that allows the administrator to manage the dictionary contents. The key contribution of this study is the use of Java and mobile technologies to develop a translation dictionary between two languages that has not been previously supported. The developed mobile dictionary is expected to meet the needs of a wide range of users such as language learners, native speakers, travelers and business professionals in Malaysia

Development of a Multimedia Courseware as a Teaching Aid for Children with Dyslexia

Dyslexia is a language based learning disability resulting in people experiencing difficulties in reading, spelling, writing and speaking. These problems are sometimes compounded by short term memory difficulties, a lack of organisational skills and time management issues which all have an impact on learning. This paper focuses on the planning, analysis and design of an e-learning courseware to teach dyslexics to read using the ‘picture thinking’ model. The development of this e-learning courseware involves transforming the traditional content of printed books from passive prints and illustrations into interactive multimedia content. The interactive multimedia content will focus on clear presentation of materials, good navigational assistance and a variety of multimedia options to tap into visual, auditory and kinaesthetic skills to support dyslexics. The targeted users will be children with dyslexia and pre-schoolers aged 5 to 7 learning to read Bahasa Melayu. A successful implementation of this courseware will be useful to the dyslexic learners as it will use picture thinking model and multisensory approach to the best of their ability instead of approaching them with the same teaching approaches used to teach their non- dyslexic counterparts

Building of the Enabled Web-Based GIS Participation System: A Tool to Enhance Community Participation in City Development Plan

This research has been conducted under the frame work of GIS interoperability infrastructure financed by the Malaysian Ministry of Science and Technology. In this paper, we discuss the development and analyze the potential application of the Geographical Information System (GIS) and Internet computing to enhance community participation in the decision making processes i.e. in Local Plan of Block 3, Melaka Tengah district as a model. The focus of this paper is on the designing and development of the enabled Web-based GIS Participation System called, GISPSS. It is considered to be similar to a Real Time Resources Discovery Server but it comprises four main complimentary components: the Map Viewer, the Objection Support, the Planning Process Documentation, and the Web Content Management. The functional features of these components are highlighted. The multi-tiered architecture forms the basis of the Enabled Webbased GIS system has been adopted in this research

An Assistive Multimedia Courseware for Dyslexics

One of the most promising areas of education is the development of computer-based teaching materials, especially interactive multimedia programs. Interactive multimedia allows independent and interactive learning, and yet presents the learning information to the learners in newly engaging and meaningful ways. This paper delivers the theoretical concepts and design of a multimedia courseware called ‘MyLexic’. ‘MyLexic’ is the first learning tool to nurture interest on Malay language basic reading among preschool dyslexic children in Malaysia. The theoretical framework proposed in the study is based on research in dyslexia theory with Dual Coding Theory, Structured Multi-sensory Phonic Teaching and Scaffolding instructional technique. Detail explanations on its learning content are also discussed. The courseware is hoped to contribute a significant idea to the development of technology in Malay language education for dyslexics in Malaysia

E-Learning for Disability: Creation, Assessment, and Implementation

This paper presents the design and delivery of X-leksia: a multimedia courseware to aid basic reading skills in Malay language among the pre-school dyslexics. The courseware has been developed based on multi-sensory teaching approach. It supports the visual, auditory, kinaesthetic elements via multimedia and “learn by doing” exercises that will reinforce each other for optimal learning. The courseware has undergone both formative and summative evaluation with dyslexics and subject matter experts from Dyslexia Association of Wilayah Persekutuan, Kuala Lumpur. The evaluation procedure, criteria and results are presented in this paper. As a result of completing the evaluation procedure, the author found that X-leksia’s approach was well received by the children and teachers alike although there is still room for improvement. The courseware is hoped to contribute a significant idea to the development of technology in Malay language education for preschool dyslexics in Malaysia
