Covid-19 related restrictions bring new challenges to all aspects and phases of higher education. At universities, remote formats are deployed or even developed both for lectures laboratory exercises. This article addresses describes the experience with lessons during pandemic time at Department Measurement Czech Technical University in Prague, Faculty Electrical Engineering. It introduces best...

Few systematic studies of play in foragers exist despite their significance for understanding the breadth of contexts for human development and the ontogeny of cultural learning. Forager societies lack complex social hierarchies, avenues for prestige or wealth accumulation, and formal educational institutions, and thereby represent a contrast to the contexts of most play research. Analysis of s...

Multiple hop routing in mobile ad hoc networks can minimize energy consumption and increase data throughput. Yet, the problem of radio interferences remains. However if the routes are restricted to a basic network based on local neighborhoods, these interferences can be reduced such that standard routing algorithms can be applied. We compare different network topologies for these basic networks...

Auditory speech perception is more accurate when combined with visual speech. Recent ERP studies suggest that visual speech helps 'predict' which phoneme will be heard via feedback from visual to auditory areas, with more visual salient articulations associated with greater facilitation. Two experiments tested this hypothesis with a speeded auditory identification measure. Stimuli consisted of ...

Network security and authentication are very important for all kinds of communication networks to assure network stability and to avoid subscription fraud. In the last years – even for wireless local area networks – mechanisms have been found to support both in a cellular network. In multi–hop networks based on IEEE802.11, security and authentication are still open issues. Mainly the low price ...
