In an N x N shared buffer switch architecture, a common buffer space is shared among output ports, which provides flexibility in resource allocation. However the problem arises when the buffer space is dominated by one or more output ports in case of imbalanced input traffic. Thus this results in an increased packet loss rates due to unfair sharing of buffer space. For this reason buffer manage...

one of the most important economic factors is potential output. in macroeconomic models and structural studies, the estimation of potential output is necessary for projections and analyzing policy performances. there exist several methods for estimating potential output. meanwhile, its estimation is a difficult and complicated matter. empirical studies and researches show that using various tec...

We present a classification-based policy iteration algorithm, called Direct Policy Iteration, and provide its finite-sample analysis. Our results state a performance bound in terms of the number of policy improvement steps, the number of rollouts used in each iteration, the capacity of the considered policy space, and a new capacity measure which indicates how well the policy space can approxim...

When the state dimension is large, classical approximate dynamic programming techniques may become computationally unfeasible, since the complexity of the algorithm grows exponentially with the state space size (curse of dimensionality). Policy search techniques are able to overcome this problem because, instead of estimating the value function over the entire state space, they search for the o...

Access control in Smart Spaces requires flexible, dynamic and powerful management approaches. Policy based management has the potential to empower users and administrators in this domain. Rigid organisational models with pre-determined policy rules limits the possibilities for users’ interactions with the space and between each other. This paper outlines a community based policy management appr...

Policies relating to contraceptive services (population, family planning and reproductive health policies) often receive weak or fluctuating levels of commitment from national policy elites in Southern countries, leading to slow policy evolution and undermining implementation. This is true of Kenya, despite the government's early progress in committing to population and reproductive health poli...
