GC: n CT: A Kaplan turbine is basically a propeller with adjustable blades inside a tube. It is an axial-flow turbine, which means that the flow direction does not change as it crosses the rotor. Figure 1 shows a simplified Kaplan turbine. The inlet guide-vanes can be opened and closed
GC: n CT: The name Triassic derives from the division of the sediments into three typical stages: Bunter, Muschelkalk and Keuper. The basin containing these sediments, reaching from the North Sea area in the north to the Iberian Penninsula in the south and from the Paris Basin in the west
GC: n CT: Electricity used at any moment is measured in watts. It only makes sense that a 100-watt bulb uses 100 watts of electricity. A desktop computer uses about 65 watts and a central air conditioner uses about 3,500 watts. Since all of the watts add up quickly, the

GC: n CT: Kinetic energy is the energy of motion. An object that has motion – whether it is vertical or horizontal motion – has kinetic energy. There are many forms of kinetic energy – vibrational (the energy due to vibrational motion), rotational (the energy due to rotational motion), and
GC: n CT: Marine current turbines: Pioneering the development of marine kinetic energy converters. This paper gives the rationale and background to an already advanced research and development (R&D) programme aimed at developing technology for the commercial exploitation of kinetic energy from marine currents. This is followed by a brief
GC: n CT: Knowledge engineering is a field within artificial intelligence that develops knowledge-based systems. Such systems are computer programs that contain large amounts of knowledge, rules and reasoning mechanisms to provide solutions to real-world problems. A major form of knowledge-based system is an expert system, one designed to emulate
GC: n CT: ESPRE is a knowledge-based system which aids in the review of requests for platelet transfusions in the hospital blood bank. It is a microcomputer-based decision support system written in LISP and utilizes a hybrid frame and rule architecture. By automatically obtaining most of the required patient data
GC: n CT: After two and a half years of intensive negotiations, a substantial extension to the Convention was adopted in Kyoto, Japan in December 1997. This Kyoto Protocol established legally binding emissions targets for industrialized countries, and created innovative mechanisms to assist these countries in meeting these targets. The
