the cúk converter, which has voltage buck and boost ability, offers high flexibility as an interface device for solar panels. in addition, current ripple can be more reduced because of two input and output inductors at both sides. this paper presents a new application of current-variable inductors in a cúk converter that reduces the size and capacity of storage elements. because of two inductor...

this study was performed to design bilayer regioselective floating tablets of atenolol and lovastatin to give immediate release of lovastatin and sustained release of atenolol. bilayer floating tablets comprised two layers, i.e immediate release and controlled release layers. the immediate release layer comprised sodium starch glycollate as a super disintegrant and the sustained release layer c...

in this investigation, ag@tio2 nanocomposite was prepared by deposition of silver nanoclusters onto commercial tio2 nanoparticles (known as p25 tio2) via photodeposition technique as clean and simple photochemical route. the synthesized ag@tio2 nanocomposite was utilized in the fabrication of dye-sensitized solar cell (dssc) chiefly because, compared to pure tio2, the electron affinity of ag@ti...

With the rapid development of the photovoltaic industry, fault monitoring is becoming an important issue in maintaining the safe and stable operation of a solar power station. In order to diagnose the fault types of photovoltaic array, a fault diagnosis method that is based on the Least Squares Support Vector Machine (LSSVM) in the Bayesian framework is put forward. First, based on the elaborat...

Carvedilol (CVD) is an antihypertensive agent with a short half-life, pH-dependent solubility, and narrow absorption window. The purpose of this research was to prepare a floating-drug delivery-system of carvedilol to increase its half-life. The present study investigates the preparation of carvedilol-floating microspheres, evaluates the floating-drug delivery-system (FDDS) (by scanning electro...

The purpose of present research work is to develop gastro retentive formulation for Moxifloxacin using various release retardants. Moxifloxacin, novel synthetic fluoro quinolone, antibacterial agent. Floating tablets of Moxifloxacin. HCl were prepared using variable amounts of HPMCK4M, HPMCK15M and HPMCK100M with effervescent mixtures by direct compression technique. Totally 9 formulations were...

ABSTRACT: Floating inductor circuits using minimum number of passive elements namely two resistors and one capacitor is reviewed in this paper. All the circuits considered in this paper are floating. Previously reported non-floating circuits are modified to be floating and new floating circuits are introduced as well. The active elements used in this paper are floating conveyor building blocks ...

Remote area electrification is a major concern for government of any developing nation. India also working it but despite continuous efforts towards remote electrification, several thousand households in are un-electrified. Several schemes have been launched by Government such areas through grid extension still many not covered under the proposed due to economic, environmental and geographical ...
