Ballistocardiography (BCG) is a promising unobtrusive method for home e-healthcare systems, and has attracted increasing interest in recent years along with technological advances in related biomedical, electrical engineering and computerscience fields. While existing systems have investigated the efficacy of BCG setups in bed, backrest, seat or scale positions, we propose to study BCG in headrest position that will allow new practical and portable applications. To this end, we designed and implemented a multi-modality sensing system including a high-sensitivity microbend fiber optic BCG sensor. In this preliminary study, we have collected multi-modality physiological data on 3 human subjects. We ran extensive analysis on BCG in correlation with ECG, and identified special characteristics of the signal in the new BCG setup. the result suggests that new appropriate computing techniques are necessary for accurately recovering the heart beat signal. therefore, we developed a novel algorithm for heart beat detection. We evaluate the algorithm withthe data and demonstrate that it can accurately compute heart rate intervals in the headrest BCG despite significant signal distortion.

Restaurants have often failed to take full advantage of modern technology to improve everyday business. Proposed is a dynamic menu that would be embedded within the physical dining table as well as a Flash® compatible - mobile telephone. this menu would include an interface controlled by a touch screen monitor or a mobile device. the menu is designed to improve the three goals of a restaurant operation: work efficiency, customer density, and customer satisfaction. Withthe ability to provide real time, dynamic information, customers'food ordering experience can be enhanced by accessing a rich variety of data before and during a meal.

there was a distinct division between the cellular industry and other telecommunication industries till end of 20th century that presented basic telephone, television, radio, computer and Internet services. the cellular communication proved to be a tremendous success and went beyond fixed line connections worldwide in 2001. the innovation in technology is increasing on one hand and it is bringing competition between the suppliers on the other hand for fulfilling customer requirements. For meeting customer specific criteria, there must be a process which can rank mobile network on the basis of their speed, coverage etc. To address this issue, we have proposed an approach in this paper for performing quantitative analysis of Universal Mobile Telecommunications System (UMTS) network and tried to evaluate the properties like utilization, throughput and response time. the quantitative analysis of the model is performed using Performance Evaluation Process Algebra (PEPA) Eclipse Plug-in.

this paper presents a preliminary study of usability and user acceptance of South African University Web Portals (UWPIs).the main purpose of this study is to evaluate web portal interfaces of South African universities for their usability and user acceptance. the motivation for conducting these portal evaluations is to suggest improvement and guidelines to enhance the usability and user acceptance of South African (UWPIs). An evaluation framework has been identified to be used as the criteria to help establish design guidelines and techniques for the study. Questionnaire based on the framework was used to collect data for the evaluation of the interfaces using user participatory method. the targeted user groups include existing students in the institutions, students seeking information, staff members, the public, potential employers and job seekers. A prototype web portal interface based on the results of the main survey will be developed to validate the results of the data analysis. the results from this study will provide guidelines for the evaluation of South African UWPIs for their usability and acceptance. Preliminary results of the pilot study show that South African UWPIs do not meet usability and user acceptance.

Many recent development environments support the visual construction of applications. Some of them use the term "component" to explain the composition process. In this paper, the assembly editor of the component development environment HOTAGENTis presented to show a possibility to visually construct agents for electronic commerce. In addition, an editor to compose new components using existing components is presented. the requirements of the composition process are described and it is shown how to use the HOTAGENT ASSEMBLYand HOTAGENT COMPONENTeditors.
