This involves having production units distribute to the consuming units through a single vertical and central distribution network. Each fl oor is served by an indirect connected substation (Figure 3). Enhancing comfort1 and reducing energy demand2 is possible when fl oorto-fl oor (rather than building-to-building) consumption is moderate (cooling) or low (heating) temperature radiant-based sur...

− The study presented in this paper aims to develop a new method for active and reactive power balancing in a four-wire stand-alone microgrid (MG), which feds single phase loads. Two unbalance compensation controllers are used, for active and reactive powers. The compensation is based on a dump load (DL) and a static compensator (STATCOM), which ensure the balance of the active and reactive pow...

The identification of objects in video sequences, that is, video segmentation, plays a major role in emerging interactive multimedia services, such as those enabled by the ISOMPEG-4 andMPEG-7 standards. In this context, assessing the adequacy of the identified objects to the application targets, that is, evaluating the segmentation quality, assumes a crucial importance. Video segmentation techn...

The probabilistic Random Access Memory (pRAM) is a biologically-inspired model of a neuron. The pRAM behaviour is described in this paper in relation to binary and real-valued input vectors. The pRAM is hardware-realisable, as is its reinforcement training algorithm. The pRAM model may be applied to a wide range of artificial neural network applications, many of which are classification tasks. ...

Current tools for automated deduction are often powerful and complex. Due to their complexity there is a risk that they contain bugs and thus deliver wrong results. To ensure reliability of these tools, one possibility is to develop certifiers which check the results of tools with the help of a trusted proof assistant. We present a framework which illustrates the essential steps to develop stan...

The politics and purpose of health care accreditation programmes around the world have changed radically from the original models of North America 50 years ago. Then they were hospitalfocused, profession-driven, voluntary, self-financing and essentially non-governmental. The 1990s saw a rapid growth of programmes with an increasing emphasis on primary care, networks, health systems and regulati...
