the relationship between field-related cognitive styles and global reading comprehension of hypertext

this study investigates the relationship between field-related cognitive styles and global reading comprehension of hypertext. technically, field dependency is prevailing dominance of field on perception of parts, while global comprehension is skim-like reading to grasp the general content. in this research project, 60 senior and junior students of arak university majoring in english literature...

CPPM Mahine: A Synchronous Permanent Magnet Machine with Field Weakening

Due to its particular configuration, the Consequent Pole Permanent Magnet (CPPM) machine allows one to easily control the airgap flux in a wide range so that the power capability of the machine is increased over a wide speed range. Two components of the flux, one almost constantcoming from the permanent magnet located on the rotor surface of the machine, and the other –variablecoming from a fie...

Application to Adaptive Control to Synchronous Machine Excitation

Self-tuning adaptive control technique has the advantage of being able to track the system operating conditions so that satisfactory control action can always be produced. Self-tuning algorithms can be implemented easily. Because the power systems are usually time varying non-linear systems and their parameters vary, adaptive controllers are very suitable for power systems. Characteristics of a...

Eccentricity Fault Diagnosis Studying for a Round Rotor Synchronous Machine

The paper presents a mathematical base modeling combined to Modified-Winding -Function-Approach (MWFA) for eccentricity fault detection of a round-rotor synchronous machine. For this aim, a 6-pole machine is considered, and the machine inductances are computed by MWFA in healthy and also under eccentricity fault. A numerical discrete-time method has been proposed to machine modeling in voltage-...
