Introduction to linear and nonlinear programming

Solid-state switch-mode rectification converters have reached a matured level for improving power quality in terms of power-factor correction (PFC), reduced total harmonic distortion at input AC mains and precisely regulated DC output in buck, boost, buck-boost and multilevel modes with unidirectional and bidirectional power flow. This paper deals with a comprehensive review of improved power quality converters (IPQCs) configurations, control approaches, design features, selection of components, other related considerations, and their suitability and selection for specific applications. It is targeted to provide a wide spectrum on the status of IPQC technology to researchers, designers and application engineers working on switched-mode AC-DC converters. A classified list of more than 450 research publications on the state of art of IPQC is also given for a quick reference.

Advances in seawater desalination technologies

There has been considerable interest in the development and applications of active filters because of the increasing concern over power quality, at both distribution and consumer levels, and the need to control reactive power and voltage stability at transmission levels. The existing approaches are classified and assessed to provide a framework of references for both researchers in this field and for generators, suppliers and consumers of electrical power who are, or may be, concerned about the problems associated with power quality and are considering installing active filters for their particular sets of problems.

Thermal analysis of ME—TVC+MEE desalination systems

The design and implementation of a harmonic current computation technique based on a modified Fourier analysis, suitable for active power filters incorporating DSPs is presented. The proposed technique is suitable for the monitoring and control of load current harmonics for real-time applications. The derivation of the basic equations based on the proposed technique and the system implementation using the Analogue Devices SHARC processor are presented. The steady state and dynamic performance of the system are evaluated for a range of loading conditions.

The eastern margin of the Gulf of Suez displays spectacular interrelationships between rift-border fault systems and sedimentation patterns. The structural and sedimentological evolution of a 100 km long segment of the well-exposed eastern margin of the Gulf of Suez rift has been studied by detailed field mapping, structural and sedimentological analysis together with analysis of Landsat TM and SPOT data. The eastern margin of the Gulf of Suez between Hammam Faraun in the north and Gebel Araba in the south is formed by a series of north-west trending, south-west dipping rift-border faults that are segmented and offset in an en-echelon pattern together with a second set of segmented, north- west trending, south-west dipping, major intra-rift faults that form the ‘coastal fault system’. In cross-section the faults are typically south-west dipping, planar domino — to gently curving listric in shape. The pre-rift stratigraphy includes crystalline Pan-African basement rocks (largely metavolcanics, migmatites and granites) and a pre-rift sedimentary succession of elastics and carbonates that ranges in age from the Cambrian through to the Eocene. Syn-rift elastics and carbonates range from the Oligocene through to the Recent and typically show depositional patterns which relate to the geometries of the extensional fault systems. Shallow marine Miocene syn-rift elastics were deposited in fault-bounded sub- basins at the rift margin and fanglomerate bodies with well-developed progradational wedge geometries formed in the hangingwalls of major rift-border faults. Continued movement along the major fault systems has deformed the pre-rift and syn-rift sequences leading to the present-day structural configurations.
