Web services hosted on mobile devices consume valuable device resources such as battery power, connectivity to network, and Global Positioning Systems (GPS) availability. In this context, a mobile client consumes web services provisioned by mobile devices, acting as service providers. The purpose of the research is to identify a framework that can possibly improve the efficiency, quality of services and discovery of provisioning web services on mobile devices. The framework considers battery life, message time and size, processing required, availability, reliability, scalability and the discovery of these Web accessible services. By using the framework that enables context-aware services, the efficiency and quality of services can be improved. Discovery of these services are improved by utilizing a hybrid model of both Mobile P2P and JmDNS.","PeriodicalId":173317,"journal":{"name":"2013 International Conference on Adaptive Science and Technology","volume":"197 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133718666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Necessarily, the UN Millennium Development Goals and 2030 South African Development Plan afforded some appreciation to this. To achieve extended reach, Community Health Workers are being deployed within rural communities to provide assistive health care at the community level. However, there is insufficient knowledge about the Community Health Workers in terms of their roles, skills and technological capabilities in a South African context. This is a barrier to unlocking the possibilities that technologies such as mobile phones can offer to facilitate and support the daily functions of these Community Health Workers. This paper articulates the findings of an initial exploratory study that was conducted in two communities in South Africa with a view of contributing to the understanding of the roles, needs and technological capabilities of Community Health Workers. The study found that most Community Health Workers work as volunteers who provide primary health care services in the community without the skills required for diagnosis. If diagnosis is required the patients are referred to health care facilities. The study also discovered that most Community Health Workers have access to, and are familiar with the basic use of a mobile phone - this creates an opportunity to implement technologies that will assist these Community Health Workers in their daily activities and thereby making positive impact in primary health care.","PeriodicalId":173317,"journal":{"name":"2013 International Conference on Adaptive Science and Technology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132567865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is shown that the relative dielectric permittivity increases by more than 5 times compared with the estimated value for the mixture. The model was developed on the basis of the tendency of the conducting carbon nanoparticles to aggregate into electric dipoles preserving the anomalously large permittivity of the composite. It is shown that the effect depends on the preparation technology. If the melt solidification occurs under ultrasound vibrations the effect decreases by a factor of 3. The proposed model can be successfully used to develop space oriented composites because they should have enhanced conductivity combined with the low relative dielectric permittivity.","PeriodicalId":173317,"journal":{"name":"2013 International Conference on Adaptive Science and Technology","volume":"105 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131335121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, many ODL students access and interact with information in a mobile context, which implies that interaction takes place in dynamic and changing environments. This presents students with a number of overlapping contextual challenges that need to be managed when accessing and interacting with information. Higher Educational Institutions (HEIs) are also confronted by these challenges as they strive to provide access through technologies that are accessible, usable, scalable and sustainable to students. Against this background, it is important to have an understanding of the categories of information that students would want to access and interact with through the devices that they privately own, of which mobile phones are the most common. This study investigated the categories of information that students would want to access through mobile cellular phones. The data capturing involved both qualitative and quantitative data. In order to get a comprehensive and representative set of information access needs it was necessary to start with open-ended questions. Based on the analysis of the 50 responses to the open-ended questions, fixed-response questions were formulated. The 84 responses to the fixed-response questions were then analyzed to determine the importance of the information access needs as well as the access frequency. The contribution of this paper is a set of prioritized information needs that provide some insight into the mobile centric information needs of students at the University of South Africa (UNISA) as an example of an ODL institution.","PeriodicalId":173317,"journal":{"name":"2013 International Conference on Adaptive Science and Technology","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122555835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In portals design, user interface is one of the critical components. Portal is a medium that Small Medium and Macro Enterprises (SMMEs) can use to advertise, grow exposure of their business and interact with their customers and community at large. This requires the portal interface to adapt to runtime changes because of the rapid update of services. This work addressed the issue of analysis of user request in order to have a clear understanding of the request. This is achievable by taking into considering the user history, preference and profile. This is realised by the design of architectural model called Dynamic User Interface (DUI) model which analyses the user request and also aggregate different components and present them as a single unit to the user. The DUI model was prototyped using Grid-based Utility Infrastructure for SMME-enabled Technology (GUISET) user interface as a use case. Experiments were conducted to compare DUI portal and Jetspeed-2 to test usability subjects. Usability was evaluated under four experiment variations: customization, adaptation after query, user satisfaction with response and portal performance. For each experiment, data was generated and presented for analysis. The results obtained show scalability and satisfaction of users with the adapted user interface on the fly.","PeriodicalId":173317,"journal":{"name":"2013 International Conference on Adaptive Science and Technology","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126566248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of Unified Communication (UC) is to seamlessly integrate the disparate communication channels into a device independent platform that can easily be managed by users. Due its focus on a largely urban and highly connected market, UC has not benefited marginalized communities. This paper discusses the design and implementation of Unicorn, a UC solution for a middleware software platform called Teleweaver which was designed to support the development of services for marginalized communities. The solution integrates services from a telecommunication container called Mobicents.
