abstract target-oriented approaches to translation studies are regarded as recent theories of translation. one of the most famous theories among these approaches is descriptive translation studies presented by toury (1995). this theory gives a new dimension to translation studies and gives importance to the descriptive rather than prescriptive studies. it also identifies three sets of transla...
Electrical steels are important alloys widely used in electrical instruments. The magnetic properties and low core loss of grain oriented silicon steels are closely related to the sharpness of Goss texture ({110} ).The direction of is the softest direction for magnetism. In this work, the microstructure and dependence of orientation density along the major texture fibers on the applied cold ro...

Within the premises of the flux-oriented theory of Crabtree & Newsholme [(1987) Biochem. J. 247, 113-120], I have used a graph-theoretic approach for calculating the Control Coefficients of metabolic pathways. It is shown that a directed graph representing the control structure of a metabolic pathway can be constructed in a heuristic manner directly from the reaction diagram of the pathway, wit...
Linear flux switching motors with simple passive segmented secondary, referred as Segmented Secondary Linear Flux Switching Motors (SSLFSMs), have low cost secondary and therefore are applicable to transportation systems like Maglev. However, it is shown that the SSLFSMs suffer from high thrust ripples. In this paper, minimizing SSLFSM thrust ripples besides maximizing its developed thrust are ...
on- the-job training on of the most effective tools for managers to cope with the changing organizational environment. it grantess suitable services to customers, particularly in public service enterprises. if such training os goal oriented, planned systematically, and tailored to the employees, job content, then not only it could increase employees and organizational performance, but also it c...
This paper presents a new rotor flux oriented linearizing control with speed estimation scheme for adjustable speed induction motor (IM) drive. In this scheme, rotor flux oriented vector control is used to linearize the IM drive, and decouple torque and flux. Also, a stator flux based flux estimator is used to estimate the synchronous speed. The motor speed is estimated by measuring only two li...
The rotor flux is estirnatcd for a direct field oriented induction machine drive using a voltage-current mode algorithm, or physical based algorithm. The estimated rotor flux is used to synthesize the components of the rotation matrix, szn(@,) and cos(@,). These angles are critical in transforming the command currents to the stationary frame such tha t field orientation is maintained. The princ...
