pipes or tubes in which fluids enter. It consists of two streams one for hot water and the other for cold water. The heat exchanger also consists of a control valve which is used to regulate the volume and mass. It also consists of cooling water couplings which are used to switch the cooling water direction from counter current to concurrent and vice versa. Introduction A heat exchanger is used in many different applications in a wide range of fields. The importance of a heat exchanger is to transfer

found in the literature. These problems have become one of the major concern‚ especially‚ with the use of power electronics devices which are sensitive to the variation of power supply. Among these problems Voltage Sag & Swell are identified as major concern to the electrical consumers. Voltage Sag is one of the most occurring power quality problems that cause severe problems and losses to industry. With the power systems restructuring and shifting trend towards distributed and dispersed generation

Information System Architectures: From Art to Science Peter C. Lockemann Fakultät für Informatik Universität Karlsruhe Postfach 6980 76128 Karlsruhe lockeman@ipd.uka.de Abstract: The presentation claims that architectural design plays a crucial role in system development as a first step in a process that turns a requirements specification into a working software and hardware system. As such‚ architectural design should follow a rigorous methodology – a science – rather than intuition –

creation of a collective leadership group in which members play distinct but tightly-knit and complementary roles is a critical factor in achieving substantive change. However‚ collective leadership is fragile. We identify three types and levels of "coupling" called strategic (between members of the

approach to the synthesis of high-molecular weight (1‚3)-β-D-oligosaccharides. Key elements of this approach is the ability to selectively‚ and in good yield‚ deprotect the anomeric position and also control the stereoselectivity of the glucosidic couplings by neighboring group participation. Selective deprotection of the anomeric position was possible using the chloroacetate group. The chloroacetate group could be selectively deprotected in good yield and was found to be markedly superior to the benzoyl

NEURAL NETWORK BASED TRANSFORMER DIFFERENTIAL PROTECTION Abstract: The role of a differential relay for power transformer is to trip during fault condition and blocks the tripping during inrush‚ overexcitation‚ CT saturation conditions of the power transformer. Conventional harmonic restrained relay may mal operate due to the presence of the second and fifth harmonic during internal faults because of non-linear loads and capacitance in the transmission lines. This project presents a technique for
