DC to AC inverters are the well-known and improved in various kinds photovoltaic (PV) and gird tied systems.However, these inverters are require interfacing transformers to be synchronized with the grid-connected system.Therefore, the system is bulky and not economy.The transformerless inverter (TLI) topologies and its grid interface techniques are
Psychoacoustical models have been used extensively within audio coding applications over the past decades.Recently, parametric coding techniques have been applied to general audio and this has created the need for a psychoacoustical model that is le emt multitool 2.0 specifically suited for sinusoidal modelling of audio signals.In this paper, we pr
Polymer-based waveguide amplifiers are essential components in integrated optical systems, as their gain bandwidths directly determine the operating wavelength of optical circuits.However, development of the wideband gain media has been challenging, making it difficult to fabricate devices with broadband amplification capability.Rare earth ion-dope
The study included investigation of effects of the thioredoxin reductase isolated from serum of human on oxidative stress induced in rats, through histopathological examination of the heart and liver, and the measurement of the saxemodel biochemical parameters, which included: thioredoxin reductase, creatine kinase, alanine aminotransferase, aspart
