ppt on a combination of shunt hybrid power filter and thyristor controlled reactor for power quality

This paper proposes a combined system of a thyristor-controlled reactor (TCR) and a shunt hybrid power filter (SHPF) for harmonic and reactive power compensation. The SHPF is the combination of a small-rating active power filter (APF) and a fifth-harmonic-tuned LC passive filter. The tuned passive filter and the TCR form a shunt passive filter (SPF) to compensate reactive power. The small-rating APF is used to improve the filtering characterist ....etc

methylcobalamin formulation stability

ABSTRACT
Mecobalamin is used in the treatment of trigeminal neuralgia, megaloplastic anemia, diabetic neuropathy and facial paralysis in Bell s palsy syndrome. A simple, an accurate and economic, precise and reproducible UV Spectrophotometry method has been developed for the estimation of mecobalamin in injection dosage form and validated by ICH guidelines. The standard (10 g/ml) was scanned between 200-400 nm and maximum absorption was recorded at 353 nm. The assay results are found to be 98.94%. The pe ....etc

Abstract:

Due to its low-power consumption, low-cost, self-organization and powerful ability to route data, ZigBee, an emerging wireless network technology, has plenty of applications; GPRS (general packet radio service) network, a convenient way to access Internet, covers widely nowadays. This paper combines GPRS and ZigBee to establish a multi-mode network structure which employs GPRS as the data transmission device in the wide-area while ZigBee in the local area. This kind of network structure, providing a simple way to setup wireless netwo ....etc

Chromatography is a technique to separate mixtures of substances into their components on the basis of their molecular structure and molecular composition. This involves a stationary phase (a solid, or a liquid supported on a solid) and a mobile phase (a liquid or a gas). The mobile phase flows through the stationary phase and carries the components of the mixture with it. Sample components that display stronger interactions with the stationary phase will move more slowly through the column than components with weaker interactions. This differe ....etc

single phase ac voltage regulators using triac and diac combination for r load and rl load

Abstract

The DIode AC switch, or Diac for short, is another solid state, three-layer, two-junction semiconductor device but unlike the transistor the Diac has no base connection making it a two terminal device, labelled A1 and A2. Diac s have no control or amplification but act much like a bidirectional switching diode as they can conduct current from either polarity of a suitable AC voltage supply.In our tutorial about SCR s and Triacs, we saw that i ....etc

COMPUTATIONALLY EFFICIENT SERIAL COMBINATION OF ROTATION-INVARIANT AND ROTATION COMPENSATING IRIS RECOGNITION ALGORITHMS
Abstract:
Rotation compensation is one of the computational bottlenecks in large scale iris-based identification schemes, since a significant amount of Hamming distance computations is required in a single match due to the necessary shifting of the iris codes to compensate for eye tilt. To cope with this problem, a serial classifier combination approach is proposed for iris-based identification, combining rot ....etc
