Optimization and characterization of porous materials have been extensively studied by various surface phenomena researchers. Efficient methods are required to predict the optimum values of operating parameters in different stages of material preparation and characterization processes. A novel method based on the application of a special class of radial(More)
The main indication of cimetidine is being H2-receptor antagonist, but studies suggest that cimetidine may also act as a non-specific stimulant of cell-mediated immunity and immunomodulator. In order to determine the immunomodulatory effect of dietary intake of cimetidine in the common carp (100 ± 10 g), subjects were fed diets containing 0 (control), 50,(More)

This paper propose a suitable structure to increase the gain and speed of low-voltage amplifiers by means of modifying the first stage of the Folded-Cascode (FC) structure and exploiting class AB amplifier with active load at the second stage. In spite of the fact that cascode structures increase the output impedance, we make an extra pole in the transfer(More)
Nowadays, usually data is transmitted through a communication channel in the form of binary codes, which undesirably their data bits can be masked and changed by noise. Detecting and correcting these errors is important. In this paper, a general formula of Hamming Code to recognize a single bit error in composite data word-parity bits is presented and an(More)
Phototransistors have many applications in Integrated Optic Receivers. In this paper, analysis of noise reactions in a Heterojunction Bipolar Transistor (HBT) which is used in the form of Three-terminal (3T) photodetector, has been presented. In this research, S/N ratio in output, noises and main parameters have been considered. This model can be used for(More)
