A lot of information provided online about stroke care is not focused on what the stroke patients really need. Furthermore, stroke patient is not the right person to gather all information about stroke care because of their limited accessibility. As a result, stroke patient did not get the correct information in their hands. The idea of this research is to insure that all the included information given through the internet is according to what the stroke people really need. This research discusses on User-Centered Design(UCD) approach, characteristics and methodologies for designing the web information system for stroke care (WISS). It uses interviews, focus group, observation, questionnaire and card sorting activities as the techniques in conducting the activities for eliciting the requirements among Malaysian users. It also discuss on eight (8) existing web-sites which offer the same information on stroke care to compare their features based on the eight (8) golden rules accordingly. This research covers four groups of users: stroke caregivers, stroke rehab centers, therapists and doctors who handle the stroke patients. Usability testing is used to evaluate the developed system for evaluation purposes. The study presents a web site as the medium to deliver the information as decided by the users. It also presents the navigation structure which is defined by user that has been iteratively design many times during evaluation process. Results of usability testing show that most of the users are satisfied with the system developed. ABSTRAK Kajian menunjukkan strok menjadi punca ketiga utama yang menyebabkan kematian di dunia.

In particular, the ability to fulfil the Service Level Agreement (SLA) and Quality of Service (QoS) on job scheduling. Service providers are obliged to meet the user’s expectation that stated in the SLA. A job scheduler’s efficiency is graded based on how well the user’s expectations are met. However, the user’s Requested Time is at best an estimate and fraught with inaccuracies to begin with. This thesis focuses on developing a new runtime prediction algorithm to improve the scheduling efficiency rather than merely relying on the user’s Requested Time. In this work, an analysis on the job submission characteristics has been carried out. The result revealed that there is a trend in the job submission characteristics. An adaptive approach is used to categorize those trends into different profiles that lead to similar predictable behaviour. A novel user profile-aware method, Runtime Prediction using Dynamic Weighted Moving Average (RP-DWMA) in making runtime prediction is proposed. Based on the simulation results on 11 production workloads obtained from Grid and supercomputer, RP-DWMA has successfully improved the scheduling efficiency. The results demonstrated an average of 41.2% performance improvement with inclusive of the resubmission cost and an acceptable average error rate of about 12.4%. Furthermore, RP-DWMA is able to adapt quickly to the dynamic changes in the submission patterns with less overhead and performs well in handling user inaccuracies in runtime estimates. In conclusion, RP-DWMA is well suited for job submission environment that requires service-oriented approaches. <br/> <br/>Description: Dissertation (M.C.S.) -- Faculty of Computer Science & Information Technology, University of Malaya, 2010. http://dspace.fsktm.um.edu.my/handle/1812/1068 Title: A middleware integrating ERP, CRM and supply chain management system using service oriented architecture <br/> <br/>Authors: Chong, Kwong Chen <br/> <br/>Abstract: ABSTRACT In the era of competitive business world, ERP, CRM and SCM system has become among the most influential enterprise systems in term of improving competitive advantages of an organization. However, most of the systems running in companies are continue to exist in isolation. They become less relevant in today business context due to lack of integrated information achievable through each of the system respectively. This dissertation introduces an idea of service-sharing system integration approach named SCAIM that consists of a conceptual model and a connector to integrate the participated systems at conceptual level. Through the development of the conceptual model and the connector, any representational and services participated are organized in a center component and integrity these systems functionalities is mapped conceptually. Hence, the capability of SCAIM to integrate ERP, CRM and SCM is tested by using different standard testing approaches. Basically, the research methodology chosen for this dissertation is survey research; hence survey questionnaire and interview are two modes of survey research used to conduct the survey and data analysis. Of 40 survey responses, majority agreed that ERP, CRM and SCM are most suitable among the business applications to be integrated to improve competitive advantages of an organization. Moreover, this research supports the idea that SCAIM increases the integration level of ERP, CRM and SCM effectively. ABSTRAK Dalam era dunia perniagaan yang kompetitif, sistem ERP, CRM dan SCM telah menjadi antara sistem-sistem syarikat yang paling menarik perhatian dari segi meningkatkan kelebihan kompetitif bagi satu organisasi.

In response to this, Rapid Application Development (RAD) based on persistence framework has been identified and adopted in this research as an approach to develop a method of designing web applications so that the whole process is quick, painless, and nearly effortless. The main objective of the research is to propose an approach to develop a toolkit to support rapid web application development leveraging on a persistence framework. The persistence framework was introduced to overcome the problem of object-relational impedance mismatch occurred in most applications that need access to a relational database. However, most persistence frameworks are difficult to configure and use, thus do not really contribute much to the improvement of software developers’ overall productivity. This research proposes suitable concepts, architecture, design and development of a rapid application development toolkit that will leverage on a persistence framework with configuration wizard to subsequently provide an easy-to-use and customisable front-end web application development environment for developers to perform rapid web application development. Unlike prior efforts, the combination of the features of rapid prototyping, code generation and configuration wizard on top of the persistence framework provided by the proposed RAD toolkit enables developers not only to deliver web applications within a shorter time frame through an easy-to-use front-end environment, but also achieve encapsulation of database access from business objects. The research was designed and implemented using Java programming language. An evaluation process carried out shows the effectiveness of the approach that makes exploration of future works possible. Abstract (in Malay Language) Sistem perisian harus dibangunkan dengan cepat untuk menyelaraskan persekitaran perniagaan yang sentiasa berubah pada masa ini. Sehubungan dengan itu, Pembangunan Aplikasi Pantas (RAD – Rapid Application Development) yang berdasarkan persistence framework (kerangka yang menguruskan penyimpanan data) telah dikenal pasti dan diterima pakai dalam kajian ini sebagai pendekatan untuk menghasilkan satu kaedah mereka bentuk aplikasi web supaya seluruh prosesnya adalah cepat dan mudah. Objektif utama kajian ini adalah untuk mencadangkan satu pendekatan untuk membangunkan satu set alat (toolkit) untuk menyokong pembangunan aplikasi web pantas yang bergantung pada persistence framework. Sebenarnya, persistence framework diperkenalkan untuk mengatasi masalah object-relational impedance mismatch (ketidaksamaan antara teknologi berorientasikan objek dengan konsep hubungan) yang banyak berlaku pada aplikasi yang memerlukan akses pangkalan data jenis hubungan (relational database). Namun demikian, kebanyakan persistence framework sukar untuk dikendalikan sehingga tidak begitu banyak menyumbang kepada peningkatan produktiviti pembangun perisian. Kajian ini mencadangkan konsep, seni bina, reka bentuk dan pembangunan set alat pembangunan aplikasi pantas (RAD toolkit) yang akan memanfaatkan persistence framework dengan adanya program kecil (wizard) konfigurasi, kemudian ia menyediakan persekitaran pembangunan aplikasi web yang mudah dikendalikan kepada pembangun perisian untuk melakukan pembangunan aplikasi web pantas. Tidak seperti dahulu, kombinasi ciri-ciri pembinaan prototaip cepat (rapid prototyping), penjanaan kod pengaturcaraan (code generation) dan program kecil konfigurasi bagi persistence framework yang disediakan oleh RAD toolkit membolehkan pembangun perisian tidak hanya menghasilkan aplikasi web dalam jangka masa yang lebih pendek melalui penggunaan muka depan persekitaran yang mudah dikendalikan, tetapi juga dapat mengurungkan akses pangkalan data dari objek bisnes. Kajian ini telah direka dan dilaksanakan dengan menggunakan bahasa pengaturcaraan Java. Proses penilaian telah dijalankan untuk menunjukkan keberkesanan pendekatan ini dan ia juga sebagai eksplorasi untuk kajian masa depan. <br/> <br/>Description: Dissertation (M.C.S.) -- Faculty of Computer Science & Information Technology, University of Malaya, 2011. http://dspace.fsktm.um.edu.my/handle/1812/1066 Title: Evaluating the performance of a Telerobotic system employing model predictive control techniques <br/> <br/>Authors: Ghaffari, Hossein <br/> <br/>Abstract: ABSTRACT Controlling robots over long distances is an important issue in robotics technology and teleoperations. In a teleoperation system the controller provides accurate transmission between master and slave manipulators. For a distant transmission, time delay and loss of data are common problems, making teleoperation systems unstable and unreliable. Due to existing vulnerabilities in web-based system, security in different robotic applications is an important issue and differing levels of security measures may be considered. This research present an approach to set up teleoperation systems with long distance communication channels like Internet via Model Predictive Control (MPC) techniques. The modified MPC scheme with a novel method of creating and transmitting the batch files for executing the commands in the server is investigated via a case study. Experimental results are used to verify the robustness of the approach in terms of tracking behavior with both variations of time-delays and packet losses in the communication network. For the experimentation, the communication network is Internet using UDP protocol while the slave robots are 6 Degrees of Freedom anthropomorphic robots with force sensors. The experiments are conducted between two remote sites of a distance 6000 km. ABSTRAK Pengawalan robot, dalam jangka masa panjang merupakan satu isu penting dalam bidang teknologi robot dan teleoperasi. Dalam sistem teleoperasi, pengawal memberi transimasi yang tepat di antara 'master' dan pemanipulasi 'slave' Untuk transimasi jarak jauh,kelewatan dan kehilangan data merupakan masalah yang berlaku kerap kali yang menyebabkan sistem teleoperasi menjadi tidak stabil dan datanya kurang sah. Ciri ciri ini menyebabkan sekuriti dalam aplikasi robotik menjadi isu penting dan tahap sekuriti yang berbeza haruslah dipertimbangkan. Kajian ini mengkaji satu pendekatan sistem teleoperasi yang menggunakan saluran komunikasi jarak jauh seperti Internet melalui teknik Model Predictive Control (MPC) Skema MPC yang telah diubahsuai dengan kaedah mencipta dan menyalurkan data fail untuk melaksanakan arahan dalam server telah dikaji melalui kajian kes. Keputusan eksperimen telah digunakan untuk sahkan keberkesanan pendekatan ini tanpa mengabaikan kedua dua variasi iaitu kelewatan dan kehilangan data dalam jaring komunikasi. Untuk tujuan eksperimen, jaring komunikasi ialah Internet yang menggunakan protokol UDP manakala robot 'slaves' yang digunakan ialah jenis '6 Degrees of Freedom anthropomorphic' yang mempunyai 'force sensors'. Eksperimen ini dijalankan di antara dua lokasi dengan jarak 6000 km. <br/> <br/>Description: Dissertation (M.I.T.) -- Faculty of Computer Science & Information Technology, Universiti Malaya, 2011. http://dspace.fsktm.um.edu.my/handle/1812/1064 Title: Personalized mathematics learning system using multimedia in lower secondary school in Malaysia <br/> <br/>Authors: Tey, Siew Kee <br/> <br/>Abstract: This study focuses on enhancing students’ learning competency in learning mathematics. Current personalized learning systems that are available are comparatively more informational instead of using practical approaches to sharpen learners’ ability in learning. Most course materials that has been designed to accommodate learners incompetency in learning are unable to initiate learners interest to take part in learning practices which can enhance their understanding and analytical ability. This study aimed to promote each learner’s learning competency by designing and proposed a prototype learning system that not only personalized learning contents which has already been implemented by others researches but also a personalized assessment model based on learners’ ability. This prototype system focuses on enhancing learners’ ability by confronting learners to their learning difficulties. This system provides learners with appropriate proportion of questions based on learners’ strength and weaknesses in learning. This system gauge learners’ interest in learning by adapting lessons material that employed the combination of multimedia components such as animation and audio-video teaching with interactivity elements. At the end of this research, learners’ performance will be evaluated through continuous assessments and learners are expected to have an improvement in term of analytical and problem solving skills and be able to recognize the patterns and key words in solving mathematical problems and that overall learning performance will be increased. Field experiments were conducted on students of age 13 to 15 years and teachers teaching Mathematics. The research method used in data gathering includes questionnaire, observations and interviews. Comparative analysis were done by comparing personalized and non-personalized systems where the analysis shows that in personalized system there is a significant improvement in learning achievement. <br/> <br/>Description: Dissertation (M.C.S.) -- Faculty of Computer Science & Information Technology, University of Malaya, 2010. http://dspace.fsktm.um.edu.my/handle/1812/1063 Title: University content management system (UCMS) framework <br/> <br/>Authors: Khalid Dhiyab Said Al-Rubaiey <br/> <br/>Abstract: With the rise in amount of contents that are created at an organization, it becomes very important to use more advance technology in order to manage the content and to ease the dissemination of information to the audience.

With the rapid development of computer hardware and network environment, hospital system is changing to digital environment for reducing time wasted and efforts. The system design and implementation shown is a process of patients' ability to book for a special appointment related to the digital data base belonging to the hospital. The objective of this study is to prepare a suitable hospital appointment system for the benefit of improved convenience for both the medical team and also the patients. Quantitative methods are used in this research in order to obtain ideas to develop the prototype of the system. This is followed by system development, by which the researcher developed a Patient Appointment System. This system was put to test by the potential users. The prototype system is used as a base to measure the feedback of the target respondents as to the acceptance of the patient appointment system. The findings of the study are used to identify the attitude, ease of use and usefulness of the proposed system. The three target groups including doctors, hospital staff and patients are not very different from each other in terms of the mean values obtained. However, the result clearly shows that the system is very useful. Overall, the hospital appointment system is an effective approach to reduce time, cost and effort to make hospital appointment. The system is conceived to be acceptable, friendly, easy to be accessed and culturally acceptable. The development and provision of quality healthcare could be promoted through the usage of ICT. The researcher believes that the prototype can be further improved to enable the hospital appointment system to be fully implemented in private hospitals as an ongoing development. The researcher considers capitalizing on quantitative methods in this study. In the stage leading to identifying the crucial contents for the proposed system, the researcher uses mainly the quantitative method. Based on the literature review and the analytical observation the researcher compiled a list of groups to be included in the proposed system. At this stage the researcher used the quantitative method to identify the responses and feedback of the potential users of the newly developed system. Upon identifying the relevant groups, the researcher was able to develop a prototype to be tested among the potential users. The questionnaire self administered questionnaire was used by the researcher to extract the feedback from the potential users of the system. <br/> <br/>Description: Dissertation (M.C.S.) -- Faculty of Computer Science & Information Technology, University of Malaya, 2011. http://dspace.fsktm.um.edu.my/handle/1812/1061 Title: Location aware system using Bluetooth technology <br/> <br/>Authors: Ganes Raj Muthu Arumugam <br/> <br/>Abstract: ABSTRACT Bluetooth is a short-range wireless communication technology, designed as a method of cable replacement between devices. Bluetooth technology is being applied to large number of devices, including mobile telephones, personal digital assistant, portable computers and various entertainment equipments. All the mention devices and the technology can be strongly related to building a location aware system. Most of the current location aware system requires bulky, costly and proprietary devices. Some are not providing accurate location information which defeats the purpose of a location aware system. The primary goal of the study is the development and prototypical implementation of an inexpensive and accurate location aware system that support automated acquisition of location and proximity information at application level. There is no current location aware system that uses the Bluetooth open source stack protocol technology which provides location information to within a centimeter. This dissertation is to use Bluetooth technology to develop an accurate and inexpensive location aware system and describes the methods to capture the signal strength information using open source Bluetooth stacks which can be widely integrated with current Bluetooth devices. Bluetooth adapters are used as agents to constantly scan the Bluetooth devices and capture the signal strength information to update the database. Bluetooth technology can accurately locate a device in a location by using multiple broadcasting stations to triangulate its position. Finally an inexpensive and accurate location aware system is developed compared with proprietary location aware system which is currently available in the market. ABSTRAK Bluetooth adalah teknologi komunikasi wayarles jarak dekat, direka untuk menghubungkan antara peranti mudah alif untuk mengganti wayar. Teknologi Bluetooth telah digunapakai secara meluas seperti telefon bimbit, alat pembantu peribadi (PDA), komputer riba dan pelbagai lagi. Semua peranti diatas adalah sangat rapat untuk dikaitkan dengan satu sistem untuk mengesan kedudukan. Kebanyakkan sistem mengesan kedudukan yang sedia ada sekarang adalah besar dan mahal. Sesetengah daripadanya juga tidak menyediakan maklumat yang tepat dimana ia telah lari dari tujuan utamanya. Matlamat utama pengajian ini adalah pelaksanaan pembangunan dan prototipikal sistem lokasi yang murah dan tepat sedar kedudukan yang menyokong pengambilalihan automatik dan maklumat kedekatan di tahap aplikasi. Tidak ada sistem lokasi yang menggunakan sumber teknologi Bluetooth open stack protokol yang menyediakan maklumat lokasi ke dalam sentimeter. Disertasi ini menggunakan teknologi Bluetooth open stack protocol untuk membangunkan sistem lokasi yang berkos murah dan menawarkan matlumat automatik yang tepat dengan menangkap kekuatan isyarat yang sedia ada di peranti mudah alih sekarang. Buat masa ini, masih tidak ada sistem seumpama itu yang menggunakan teknologi protokol Bluetooth untuk menyediakan maklumat kedudukan. Pengesan Bluetooth dijadikan sebagai agen untuk menyesan peranti Bluetooth dan menyimpan maklumat kedudukan didalam database. Teknologi Bluetooth ini boleh mengesan secara tepat peranti didalam satu lokasi dengan menggunakan beberapa stesen pemancar. Akhirnya, satu sistem yang berkos rendah tetapi menyediakan maklumat lokasi yang tepat dicipta untuk menggantikan sistem sedia ada yang besar dan mahal. <br/> <br/>Description: Dissertation (M.C.S.) -- Faculty of Computer Science & Information Technology, University of Malaya, 2011. http://dspace.fsktm.um.edu.my/handle/1812/1060 Title: Needleman-Wunsch and smith-waterman implementation for Spam/Uce inline filter <br/> <br/>Authors: Chiew, Ming Thong <br/> <br/>Abstract: Spam have been a significant problem as it consumes bandwidth of the internet, waste surfers time, waste computational resources of internet service providers and reduce the efficiency of email as a way of communication. Despite various anti spam solutions introduced, spam mails tend to be able to avoid detection by slightly modifying their spam signature. This helps to avoid anti-spam solutions from successfully detecting the keywords in emails that are closely associated with spam. Two algorithms named Needleman-Wunsch and Smith-Waterman will be implemented on FPGA as spam detection engine. Both algorithms share its origin from the theory of dynamic programming and are normally implemented in bioinformatics for sequence alignment. As both are well-known for their ability to detect sequences with slight changes caused by mutation, these two algorithms will be used to detect spam messages that slightly change its spam keyword. FPGA have been selected as the device for implementation. As hardware are faster than software, using FPGA helps to reduce the scanning time and reduce the CPU load of the computer. The advancement of FPGA technologies help to make it capable of becoming a standalone scanning unit. The effectiveness of both algorithms in spam scanning will be looked into. The corpus from Text Retrieval Conference (TREC 2007) will be used to test the effectiveness of the anti-spam engines. <br/> <br/>Description: Dissertation (M.C.S.) -- Faculty of Computer Science & Information Technology, University of Malaya, 2011.
