Inherent limitations on the computational power of sequential uniprocessor systems have lead to the development of parallel multiprocessor systems. The two major issues in the formulation and design of parallel multiprocessor systems are algorithm design and architecture design. The parallel multiprocessor systems should be so designed so as to facilitate the design and implementation of the efficient parallel algorithms that exploit...

One of the key contributors to the spread of the HIV epidemic is the prevalence of risk behaviour, such as unprotected sexual contact and the sharing of infected hypodermic syringes, within the susceptible population. We assume that risk behaviour is a social phenomenon and that the propensity of any given individual to engage in such behaviour depends on the norms within their social environment. The likelihood of any given susceptible...
