- Description: This paper investigate the challenges faced by the occupants’ of low-income housing with their government installed solar water heaters in South Africa, Tshwane Metropolitan Municipality. The paper primarily investigates the challenges faced by the housing occupants since the solar heaters were installed in their low income houses. The data used in this paper were derived from both primary and secondary sources. The primary data was obtained through the survey method, while the secondary data was derived from the review of literature. The primary data for the study was collected through a structured questionnaire survey distributed to a sample of low-income households in a metropolitan municipality in South Africa. The household survey revealed that the low-income housing residents’ occupants’ faces challenges with regards to the leakage of the solar heaters and the noise from the heaters whenever the hot water taps are opened. The study gives an insightful view of the importance of using solar water heaters in energy conservation and lessening electricity financial constraints on the low-income households. The study adds to the knowledge on low income housing solar water heating in South Africa, with specific emphasis on the challenges faced by the occupants’. Further, findings from the study could be used for the development of sustainable structures in order to give access to energy and hot water to the poor and providing a better path to the improvement of life and empowerment through alternative energy usage in low-income households’ in South Africa.

- Description: We suggest a method of optimizing resource allocation for real time protocol traffic in general, and VoIP in particular, within an H.323 environment. There are two options in the packet network to allocate resources: aggregate peak demand and statistical multiplexing. Statistical multiplexing, our choice for this case, allows the efficient use of the network resources but however exhibits greater packet delay variation and packet transfer delay. These delays are often the result of correlations or time dependency experienced by the system’s queue due to the variations observed in different point processes that occur at a point of time. To address these issues, we suggest a queuing method based on the diffusion process approximated by Orstein-Ulenbeck and the non-validated results of Ren and Kobayashi.

- Description: A new decoding method is presented for permutation codes obtained from distance-preserving mapping algorithms, used in conjunction with M-ary FSK for use on powerline channels. The new approach makes it possible for the permutation code to be used as an inner code with any other error correction code used as an outer code. The memory and number of computations necessary for this method is lower than when using a minimum distance decoding method.
