The paper gives an overview of the multiple-input multiple-output (MIMO) systems and discusses their benefits enabling an increase in the system capacity and an increase of system reliability. The former is attained by signal multiplexing and the later by space encoding. The basic algorithms required for a proper operation of the MIMO systems, i.e. channel estimation, equalisation, optimal and ...

This paper was presented in poster form at and in the proceedings of the QCMC 2008. It is a summary of a fuller paper to appear separately. The classical product state capacity of a noisy quantum channel with memory is investigated. A forgetful noise-memory channel is constructed by Markov switching between two depolarizing channels which introduces non-Markovian noise correlations between succ...

background the lack of effective use of research evidence in policy-making is a major challenge in most low- and middle-income countries (lmics). there is need to package research data into effective policy tools that will help policy-makers to make evidence-informed policy regarding infectious diseases of poverty (idp). the objective of this study was to assess the usefulness of training works...

Landauer’s principle [1] states that the erasure of classical information leads to an increase in the entropy of the environment by at least the same amount. The importance of this principle is the insight that it is not the act of obtaining information that necessarily generates heat and therefore entropy, but the erasure of information. This profound insight has led to the resolution of the p...

This paper addresses the possibility of capacity withholding by energy producers, who seek to increase the market price and their own profits. The energy market is simulated as an iterative game, where each state game corresponds to an hourly energy auction with uniform pricing mechanism. The producers are modeled as agents that interact with their environment through reinforcement learning (RL...
