ADELINE SNEHA, K. KUMAR, V. BENS JOIE VICTOR, J. ARAN GLENN
Abstract: The main objective of the paper is The growing concern for energy saving has increased the usage of LED- based Street Lights, Electronic Chokes, Compact Fluorescent Lamps, And Inverter-Fed Drives. Hence, the load profile seen by the electrical grid is undergoing a notable change as these devices have to operate from a dc source. Photovoltaic (PV) being a major energy source, the loads can be connected directly to the dc bus. A grid-connected PV system involves a power source (PV array), a power sink (load), and two power sources/sink (solar and ac grid), and hence, a power flow sharing system is required to balance the power flow among these sources. This method is reduce the burden of input voltage because whenever the solar output reduces then the input voltage share to AC grid so the distribution AC grid and solar panel is takes place

A Modified Three-Phase Four-Wire UPQC Topology with Reduced DC-Link Voltage Rating
DIVVESWARA REDDY.M, R.LOKESWAR REDDY
Abstract: This paper introduces a new concept of optimal utilization of a unified power quality conditioner (UPQC). The series inverter of UPQC is controlled to perform simultaneous 1) voltage sag/swell compensation and 2) load reactive power sharing with the shunt inverter. The active power control approach is used to compensate voltage sag/swell and is integrated with theory of power angle control (PAC) of UPQC to coordinate the load reactive power between the two inverters. Since the series inverter simultaneously delivers active and reactive powers, this concept is named as UPQC. A detailed mathematical analysis, to extend the PAC approach for UPQC, is presented in this paper. MATLAB/SIMULINK-based simulation results are discussed to support the developed concept. Finally, the proposed concept is validated with a digital signal processor-based experimental study

Development of Low Temperature Oxidation Process Using Ozone for VLSI
YUDHVIR SINGH CHIB
Abstract: With decreasing size of MOS transistor the thickness of gate oxide (SiO2) is reaching in regime where it is just 2-3 atomic layers thick about 1 to 1.5 nm thick because of thin oxide layers there is direct tunnelling of charge carriers through gate oxide, and the transport of charge carriers through defects in gate oxide. The increasing leakage current through gate oxide is proving to be a showstopper to the scaling of MOS transistor, and saturating the Moore’s Law. For the applications, where the devices are need to be fabricated on plastic, glass or poly-crystalline silicon substrates a good quality of oxide is required to be grown at low temperatures. In this work a low temperature, defect free oxide growth technique using ozone is presented and we study the effect of various ambient temperatures on growth of SiO2, the effect of pre cleaning and passivation on quality of ozone grown oxide in terms of bulk defect density, Si-SiO2 interface trap charge density and on oxide life time is presented.

A Grid Connecetd Fuel Cell Based On Boost Inverter System
B.HARITHA, P.DHANAMAJAYA
Abstract: In this paper, the boost-inverter topology is used as a building block for a single-phase grid-connected fuel cell (FC) system offering low cost and compactness. In addition, the proposed system incorporates battery-based energy storage and a dc–dc bidirectional converter to support the slow dynamics of the FC. The single-phase boost inverter is voltage-mode controlled and the dc–dc bidirectional converter is current-mode controlled. The low- frequency current ripple is supplied by the battery which minimizes the effects of such ripple being drawn directly from the FC itself. Moreover, this system can operate either in a grid-connected or stand-alone mode. In the grid- connected mode, the boost inverter is able to control the active (P) and reactive (Q) powers using an algorithm based on a second-order generalized integrator which provides a fast signal conditioning for single-phase systems. Design guidelines, simulation, and experimental results taken from a laboratory prototype are presented to confirm the performance.

Improvement of BER for OFDM using Equalization and Windowing for AWGN and Rayleigh Fading Channels
NIKHIL BHARDWAJ, ANKUSH KANSAL
Abstract: The orthogonal relation between the carriers among different users is well known in OFDM. The overlap of spectrums of various users can be achieved thereby enhancing the spectrum efficiency of the communication system. OFDM is a popular multicarrier modulation technique which is currently being explored for use in the IEEE 802.11e (WiMax) standard. In OFDM, the orthogonality between the closely spaced sub-carriers is important for overcoming the phenomenon of inter-carrier interference (ICI) leading to a reduction in the Bit Error Rate (BER) performance of the system. A technique for shaping the time portion of our measured data so as to minimize the effects of the edges thus reducing the leakage that arises out of the spectrum of FFT is called windowing. The Raised Cosine (RC) window is a period of raised value of cosine function so the negative peaks of the window just touch the nil mark, hence giving its name. In order to protect the transmitted signals against the effect of multipath channels i.e. the inter-symbol interference (ISI), a cyclic prefix is added with the duration which is greater than the delay of multipaths. The phase and amplitude of the received signal also suffers due these effects. As a solution to this, some sub-carriers are sent as a reference in order to determine the role of the multipath channel. Having this estimation, the equalization technique is employed which results in the compensation for the detrimental signal effects created as a result of the multipath channels. Here, a linear equalizer namely Zero Forcing (ZF) Equalization is used in conjunction with Raised Cosine (RC) Windowing approach on traditional Orthogonal Frequency Division Multiplexing (OFDM) system using the modulation technique of 16-QAM modulation at 𝟏𝟎−𝟐.𝟗 Bit Error Rate (BER). The result is that a 5 dB improvement is achieved in the Signal-to-Noise Ratio (SNR) value for Additive White Gaussian Noise (AWGN) Channel as compared to traditional OFDM used in the same channel model. And a 15 dB improvement is achieved in the Signal-to-Noise Ratio (SNR) value for Rayleigh Channel as compared to traditional OFDM for the same channel model at 𝟏𝟎−𝟐.𝟗 Bit Error Rate (BER).

DR. MRS. A.J.VYAVAHARE
Abstract: Medical image segmentation is a difficult problem due to the fact that these images commonly have poor contrast and missing details due to different types of noise and mostly medical images are fuzzy in nature, and segmenting regions based intensity is the most challenging task. Here region growing algorithm is used for segmentation in which selection of seed is important for that connected component is used. Our aim is to study anatomical structure, identify the region of interest, measure abnormality and help doctors in planning for early diagnosis. Connected component labelling works by scanning an image, pixel-by-pixel in order to identify connected pixel regions.\Blood Cell images for segmentation are taken. Leukaemia is a type of blood cancer, and if it is detected late, it will result in death. Leukaemia occurs when a lot of abnormal white blood cells produced by bone marrow. The existence of abnormal blood can be detected when the blood sample is taken and examined by haematologists. Microscopic images will be inspected visually by haematologists and the process is time consuming and tiring. Main objective of analysing through images is to gather information, detection of diseases, diagnosis diseases, control and therapy, monitoring and evaluation. At the end different parameters are calculated from quality metrics to define the accuracy of the algorithm.
