In this paper effective method of FSM implementation in Embedded Memory Blocks of FPGAs structures is presented. Memory blocks allow implementation of sequential machines in a way that requires less logic cells than the traditional flip-flop based implementation. This may be used to implement sequential parts of the design, saving logic cell resources for more important sections. Unfortunately the size of the memory available in programmable devices is limited. In addition, these blocks can be arranged in limited number of configurations. These features require specific implementation approach to utilize the capacity of each EMB in highest possible degree. To reduce memory usage decomposition-based methods can be successfully applied. In order to effectively use available memory blocks one can build a logic network, where large logic encoding functions can be implemented in EMBs. An appropriately chosen decomposition strategy allows very effective utilization of available EMBs.

In today's global market scenario enterprises unit building collaborative environments, whereby global manufacturing represents a key issue for ensuring market share. An unequivocal communication form among all involved process agents, i. e. human and machines, constitutes a crucial requirement. Referring to the shop-floor level, this isn't easily achievable due to the different professional and cultural backgrounds of the involved machine operators. In this paper an innovative man-machine interaction concept for simplifying human tasks will be presented. A prototype based on the Ontology Filtering System has been developed. It enables formalisation of natural language instructions for multi-purposes in automation technology. Preliminary trial tests have been performed and show suitability towards a future use in the production field.

As logical consequence of a drastic growing automation degree the relevance of improved Human-Machine Interaction systems is stressed as one of the essential key issues towards the future production scenario. In particular in the automotive sector market competitive reasons lead to increasing product diversification and, therefore, to the need of innovative concepts for flexible manufacturing systems. Consequently, also developments like standard and user-friendly interaction systems assume a paramount importance as contribution in stabilizing innovation leadership. An advanced factory automation system for easy corrections of deburring and dressing results, based on industrial robots, has been developed and successfully employed in industrial context. Since it has shown high efficiency, it has been further developed towards its use in further applicationfields. This paper points out related development aspects.

This article presents the methodology for calculation of the optimum size of a Photovoltaic (PV) system. Long-term data of PV radiation were used to calculate the average power generated by a PV generator for every hour of a typical day in a month. A load of a typical house in the south of Algeria ( desert area) was used as a load demand of the system. For a given load and a mixed multiple criteria were used for programming problem, the types and sizes of PV modules generators was calculated based on the minimum cost of system. We investigated the Genetic Algorithm (GA) for optimally sizing a PV power system. We define that the objective function is the total cost where it is the sum of the initial cost, the operation cost and the maintenance cost. We determine an optimal configuration of PV generating systems where the total cost is more optimal using GA. A computer program has been developed to size system components to match the load of the site in the most cost. A cost of electricity, an overall system cost is also calculated for each configuration. The study was performed using a graphical user interface programmed in MATLAB.
