With the advantages of spatial multiplexing multi input output (MIMO) systems in terms high transmission capacity, complexity detector at receiver side such is a major issue. Performance, bit error rate (BER) studied for interleaved coded modulation (BICM) MIMO systems. List based generation (bits) soft values considered 2 by 2, 4 with 16,64 quadrature amplitude (QAM) and different list sizes u...

We propose a declarative framework for modelling multi-agent systems and specify a number of properties of these systems and agents within them. The framework is parametric with respect to an input/output semantics for agents, whereby inputs are the agents’ observations, and outputs are their actions. The observations include actions performed by other agents and events happening in the world. ...

Learning of mathematical concepts is a crucial point for high school students as well as students in science and engineering disciplines. In order to facilitate the learning of these abstract concepts we have developed a system to interactively explore these concepts based on a multi-touch table. The table is used as I/O device to additionally stimulate the haptic sense and to allow simple and ...

Normative systems in a multiagent system must be able to evolve over time, for example due to actions creating or removing norms in the system. The only formal framework to evaluate and classify normative system change methods is the so-called AGM framework of theory change, which has originally been developed as a framework to describe and classify both belief and normative system change. Howe...
