In this paper a high gain low noise Op-Amp has been designed. In designing of a high gain Op-Amp, for large values of coupling capacitor, gain will decrease. Since our requirement was to increase the gain, so we have designed a three stage Op-Amp. Our designed circuit provides gain of 78.4 dB, which is very much larger than two stage Op-Amp. There is a trade-off between various parameters like Phase margin, gain, slew rate etc. For example, to achieve larger values of GBW, PM will decrease. We have compared the results for two values of input common mode range. Improvement in the designed circuit is done to achieve the desired GBW by recalculating the transistor's W/L ratios and then simulating the results. Gain Bandwidth product of 176.9 MHz and Phase Margin greater than 60 degrees is achieved but at the cost of power dissipation and area. The Op-Amp is designed in gpdk 180 nm CMOS technology.

Wireless sensor networks become popular due to its attracting applications like monitoring and tracking. A sensor network is composed of a large number of sensor nodes, which are densely deployed and relay on limited battery power. In an Ad-Hoc network better Quality of Services can be achieved either by using high transmit power or by reducing number of hops. Transmitting at unnecessarily high power reduces the life time of sensor node as well as network. One of the goals of forming a network is to have power optimization-that is, each sensor node should be able to communicate with any other sensor node via less number of hops. Involving less number of intermediate sensor nodes in a route provides better QoS as well as rest sensor nodes can be involved in other transmission. The strategy of using optimum number of hop in multi hop communication is to provide less number of transmission in a route, which provides less involvement of semiconductor noise, signal interference, fading, scattering and shadowing, which ultimately improves QoS and also preserve the power of other sensor nodes.

A design of compact multi band circularly polarized asymmetrical fractal boundary microstrip patch antenna with DGS (defected ground structure) and fractal boundary techniques has been proposed. Using the DGS technique a cross slot and circle are cut away at the centre of the ground plane to enhance the single band to multi band. The structure is asymmetrical along to the principal axes (x, y) because the radius of fractals are different and probe feed is applied at the diagonal of square patch then the excellent CP(circular polarization) is achieved. In the both techniques the proposed antenna sizes also reduce, besides the gain and directivity increase. Experimental results show as 10 dB return loss, gain and circular polarization at the frequencies 2.58, 3.02, 5.58, and 6.44 GHz. More over the 50 ohms feed position is optimized by moving the feed point along the diagonal of the square patch and get the effective gain and directivity grater then 6 dB at each frequency. The overall dimension of the proposed antenna is 42×42×3.3 mm3. This proposed antenna is used for Wi- MAX and WLAN applications.

This paper proposes and describes a system, to classify skin lesion as malignant or benign. There are over 200 different known cancer in which malignant melanoma, is the most dangerous form of skin cancer, and have a good prognosis if treated in the curable early stages. The purpose of the research is to develop, implement and test an application, on clinical images taken using high speed cameras, to detect melanoma in early stage. The proposed system is based on TDS (Total Dermoscopic Score) calculation with preprocessing and OTSU's segmentation method for classification of skin lesion as non-cancerous (Benign), suspicious or cancerous (melanoma). The system has been tested on a dataset of 30 lesions (16 images of malignant lesions and 14 benign lesions). The result of experiment shows that preprocessing steps and OTSU's segmentation with ABCD algorithm provide more accurate result.

In this paper, we have tried to make energy efficient ALU on 90nm based Virtex-4 FPGA using different I/O standards, as with the scaling of technology power dissipation has become a major concern for high performance ALU design. As 50% of the total power of ALU is dissipated only in clock and I/O pads, hence in order to make it energy efficient clock gating technique is introduced and the analysis of power dissipation has taken on different I/O standards. It is Wi-Fi enable because we are operating our ALU on frequencies of different IEEE. We are analyzing the value of power dissipation using different I/O standards and on different Wi-Fi channel frequencies. We are achieving reduction in total power dissipation to 95.13% with LVCMOS15 and 95.18% with LVDCI_15 and after introducing Clock Gating we are achieving reduction in total power dissipation to 95.35% with LVCMOS_15 and 94.99% with LVDCI_15.

This paper has the following objectives: (1) finding the solution of economic dispatch problem using angular fuzzy sets and a variation factor, and (2) formulate a new technique for including risk management in the solution of economic dispatch problem. This new technique uses a method based upon angular fuzzy sets and a variation factor for calculating risk associated with variations or uncertainties involved in the solution of economic dispatch problem. Since the cost curve for each generator has inaccuracies and uncertainties, there is a need for including risk management in the solution of economic dispatch problem. This is to be noticed that inclusion of risk management in the solution does not reduce uncertainties, but it is providing a more accurate and precise solution considering uncertainty. Thus, this paper presents a method based on angular fuzzy sets and a variation factor that is capable of modeling economic dispatch problem including risk management.

The design of Digital Finite Impulse Response (FIR) digital band-pass filter using two Heuristic Optimization Technique have been implemented. Digital FIR Filters are better than Infinite Impulse Response Filters due to their stability and having linear phase. This paper explores the two heuristic optimization techniques namely Particle Swarm Optimization and Differential Evolution. The evaluation of performance of DE algorithm and PSO algorithm has been done and results performs have been compared on the basis of their control parameters. The achieved results show that the Differential Evolution Algorithm better than that of Particle Swarm Optimization in terms of achieved magnitude error and ripples in pass-band and stop-band.

In recent years, long period fiber grating (LPFG) has been demonstrated as the most important fiber-optic device for numerous sensing applications. Various characteristics of LPFG make it attractive in the measurement of temperature, strain, bending radius, external index of refraction etc. This proposed work explores the feasibility of utilizing LPFG for temperature and strain sensitivity enhancement. Basically, the shift in resonant wavelength of LPFG depends on thermo-optic and strain-optic effect. By enhancing these effects using optimization of thermo-optic and strain-optic parameters, both resonant wavelength shift and sensitivity can be increased. Using this concept sensitivity of 19.32nm/oc for temperature range 25oc to 140oc and sensitivity of 53.2pm/με for strain range 0με to 38000με is achieved in this work.
