Reliable Real-Time Communication for Future ITS (Intelligent Transport Systems) using HWA (Heterogeneous Wireless Access)AFGHANI, AHMAD January 2011 (has links)
In this research oriented master’s thesis we have proposed a future vision of ITS (Intelligent Transport Systems) by utilizing the novel concept of HWA (Heterogeneous Wireless Access). Our proposal is backed by the investigation of the results of experiments conducted at CERES (Centre for Research on Embedded Systems), Halmstad University, Sweden to evaluate the quality of communication for V2V and V2I by using the IEEE 802.11p standard. We have also identified the expected scenarios with need of any other communication technology in replacement of IEEE 802.11p for V2V and V2I communication. We have also investigated the relevant research projects, experiments and their results on the basis of predefined constraints. In the investigated research projects the concept of HWA has been correlated with our proposal of HWA for ITS. We have identified that for smooth integration of any communication technology with IEEE 802.11p, an efficient and smart vertical handover protocol or method will be required. We have presented a blue print of a custom designed vertical handover technique which can be implemented for future ITS with further enhancements and experimental evaluations. We have also evaluated the worst case scenarios to assess the suitability of the HWA for the ITS. We proposed few solutions based on the evaluation of communication scenarios for the integration of IEEE 802.11p with other wireless communication technologies. Finally we have provided some conclusions and suggested future researches which must be conducted to realize the dream of ITS with support of HWA.

An analysis of musanda as an institution within the Thulamela Local Municipality and the current South African public service delivery systemMadzivhandila, Muthuhadini Alfred 05 1900 (has links)
PhD (African Studies) / Centre for African Studies / The Thulamela Local Municipality is currently experiencing a plethora of public service delivery challenges. This often leads to court litigation and disputes with the institution of musanda. These public service delivery challenges, conflicts and court disputes in many cases leave the communities within the municipality deprived of basic services as a result of slow or a complete lack of service delivery.
musanda is a Venda word that refers to the place where the thovhele (king), khosikhulu (paramountcies), khosi (chiefs), gota (headman), mukoma (petty headman), vhakoma (queen mother), vhatanuni (wives), vhakololo (princes/princesses), khadzi and makhadzi (royal aunts), ndumi (king/chiefs’ brother) and the rest of this royal structure resides. As such it also refers to the institution of royal governance. The proposed study aims to analyse the place of musanda as an institution within public service delivery and within the whole process of decentralization of services in the Thulamela Municipality.
The study focuses mainly on the current public service delivery system of the government and the role of the institution of the musanda in that process. The basic service delivery system that receives direct attention falls under the Government Cluster, which covers Social Protection, and Community and Human Development. These divisions deal with Cooperative Governance and Traditional Affairs, Water and Sanitation, Human Settlements, Rural Development and Land Reform, Basic Education and Sports and Recreation. These are the services that are supposed to be rendered by municipalities. The analysis aims to determine musanda’s position in the whole process of providing the public services indicated above.
