A Kalman filter is a concept that has been in existence for decades now and it widely used numerous areas. It provides prediction of the system states as well uncertainty associated to it. The original can not propagate correct way when variables are distributed normally or there correlation measurements systematic error measurements. For these reasons, have variations filter, most them mathema...

The object of the study is a three-phase shunt active power filter, which consists two-level voltage inverter, capacitive storage device and damping RL-link. Decomposition according to rate motion dynamic system makes it possible divide this into two subsystems, interconnected by control. influence characteristics low-pass acts as subsystem communication between stabilization circuit on capacit...

Switching power converters are widely used due to their excellent efficiency, but they inherently generate ripple. Passive low-pass LC filters have been traditionally employed to meet ripple and EMI specifications [1]. These passive filters can contribute considerably to the volume and weight of a power converter. In particular, capacitors can become relatively large in order to meet strict rip...

With the widespread use of harmonic generating devices, the control of harmonic currents to maintain a high level of power quality is becoming increasingly important. An effective way for harmonic suppression is the harmonic compensation by using active power filter. This paper presents a comprehensive survey of active power filter (APF) control strategies put forward recently. It is aimed at p...

The present report describes the fabrication technique and dosimetry aspects of a desktop numerically controlled milling machine (NC-Mill) based a compensator system that uses lead clay (Shield cray, Reactor Experiments, Inc., U.S.A.). Effective path lengths of patients were determined for CT image sets using the ray-tracing technique and converted to compensator thickness with the equivalent T...

AbstractIn Time Interleaved Analog to Digital (TIADC) conversion process, multi-mismatches can be occurred these mismatches highly degrade the system performance. Different mismatches can be frequency mismatches, offset mismatches, timing mismatches and gain mismatches. Due to different Hardware delays and it happens because TIADC ICs are not identical and goes worse when multiple chips are use...

background: increasing the complexity in modern radiotherapy techniques have increased the delivery time lowering consequently the treatment efficacy. through simulating the delivery time delay encountered in such techniques, its’ effect on two cancer cell lines and the compensating doses given to prevent such effect was investigated. materials and methods: f10b16 and 4t1 cancer cell lines were...
