(frequency) and magnitudes of flux‚ current and voltage vectors are adjusted. Instantaneous positions of these vectors are not controlled. Therefore‚ space vector control methods have been strongly developed. In this case‚ not only angular speed (frequency) and magnitudes of flux‚ current and voltage vectors‚ but also instantaneous position of these vectors is controlled. This ensures excellent dynamic and stable steady state operation of space vector control methods.

1 Chapter 1 Definition and Basic Concepts Thermodynamics is defined as the science of energy. Originally derived from Greek words : therme (heat) and dynamics (power) – descriptive of early attempts at conversion of heat into power. Modern interpretation includes all aspects of energy and energy transformations‚ power generation‚ refrigeration‚ and the relationships among properties of matter. There are two approaches in thermodynamics studies: (1) classical thermodynamics – a macroscopic

Basic Ecological Concept Levels of Organization Cells- are composed of Cell Membrane‚ Nucleus and Protoplasm. Tissue-is an aggregation of cells performing a common function or functions. Organs- is the aggregation of tissues usually forming a definite shapes‚ and performing a definite function within an organ system. Organ System-is a group of organs that perform coordinated functions together to keep the organism alive and functioning well. The scope of the biology includes the study of all
