This paper analyzes the characteristics of physical layer signals, communication protocols, and the timing of PROFIBUS-DP, at last proposed a kind key technologies diagnosis scheme of PROFIBUS-DP, which based on FPGA. The scheme requires only a few peripheral circuits and use of the FPGA logic synthesis external signal, can be completed in two-way isolation of the physical layer status of DP, data flow direction, baud rate detection and other functions, which can be applied to diagnosis failure of PROFIBUS-DP.

Directed Cooperation in Multihop Wireless Sensors NetworkThis paper proposes a relational abstraction for Wireless Sensors Network where node can identify its neighbors around it. Because of limited radio link range only some of nodes have a direct contact with the base station and transmission is carried out in a multihop way so information is send from one node to another towards the BS. We propose a relation π that represents cooperation between nodes and takes advantages of topological properties of the network. Based on the hop-distance from the BS any nodekcan determine a setN<(k) that consists of nodes to which/kshould send messages in order to retain a data-flow direction towards the BS.

Abstract Geothermal energy source is the heat from the Earth, which ranges from the shallow ground (the upper 100 m of the Earth) to the hot water and hot rock which is a few thousand meters beneath the Earth's surface. In both cases the so-called open systems for geothermal energy resource exploitation consist of a groundwater production well to supply heat energy and an injection well to return the cooled water, from the heat pump after the thermal energy transfer, in the underground. In the paper an analytical method for a rapid estimation of the ground water flow direction effect on the coupled production well and injection well system will be proposed. The method will be illustrated with solutions and images for representative flow directions respect to the axis of the production/injection well system.
