The primary challenges of petroleum industries are to provide a secure quantity and quality of water resources and how to manage the generated wastewater adequately. Appropriate application of water treatment systems would play a substantial role in drilling operations. Therefore, wastewater management and controlling the amount of produced hazardous materials should be significantly taken into consideration...
In this paper, handwritten farsi numeral recognition task (0–9) is developed using Hamming neural network circuit based on single electron transistors. simulations were done using Hspice and MATLAB softwares, which in comparison with SIMON software to have high speed in simulink area.
This paper discusses modeling and simulation of three structures that called double gate MOSFET (DG-MOSFET) and linearly doped double gate MOSFET (LD-DG-MOSFET) and lightly doped drain and source double gate MOSFET (LDDS-DG-MOSFET) at the quantum transport level, with the nonequilibrium Green's function (NEGF) method. We have proposed LDDS-DG-MOSFET structure instead DG-MOSFET and linearly doped double...
In this paper, a 10-bit 1-GSample/s Nyquist current-steering digital-to-analog converter (DAC) based on Carbon Nano Tube Field Effect Transistor (CNFET) technology is presented. All the basic building blocks of current-steering digital-to-analog converter are implemented by carbon nanotube field effect transistor. Supply voltages are under 1V. This design has used a pseudo-segmented structure and...
In this paper, a new lossy technique based on wavelet transform for compression of breast ultrasound images is presented. The experiments are performed on 16 different wavelet functions and the quality of reconstructed images is evaluated by using Compression Ratio (CR), Normalized Mean Square Error (NMSE), Normalized Absolute Error (NAE), and Peak Signal to Noise Ratio (PSNR) criterion. An ultrasonographer...
In this paper, we present the design and analysis of a 3-5 GHz ultra-wideband (UWB) low-noise amplifier (LNA) in a 0.18 mum CMOS process. Simulation results show a power gain of 14 dB with a variation less than 0.5 dB over 3-5 GHz, input and output return loss lower than -9 dB and -8.5 dB, respectively, and noise figure lower than 2.4 dB in the band of interest. The input-referred 1-dB compression...
