Development of Logic Skills in High School Students: A Proposal Based on Neuroscience
Narúsci dos S. Bastos, Diana F. Adamatti, Fernanda A. H. Carvalho
Abstract: This paper proposes a study on the development of logic skills in high school students, based on Neuroscience. In order to investigate the possible contributions of computational logic training to the development of logical thinking in high school students, our approach tries to identify possible changes in brain physiology pre and post computational logic training and to characterize brain activity during resolution of the logic test problems. To conduct this study, the collection of brain signals was required in two stages: before the training in computational logic and after it. The data were taken while the students solved some logic questions. From these data we analyzed the areas with greater brain activity during the resolution of each proposed question, which they were collected through non-invasive technique, using an EEG machine. The results of our study are promising, even that initial, because they can contribute to a better understanding of the brain areas that suffer post-training changes in computational logic, and the importance of teenager students learn computational logic.
Keywords: computational logic, Neuroscience, Brain-computer interface.

Noise Estimation and Reduction to Improve Image Quality in Singly Image - Survey Paper
Tarun Pare, Aditya Sinha, Pankaj Richariya
Abstract: Noise is major issue observed during the image processing in image processing applications. These noise levels have to be predicted and after estimation get it reduced to certain maximum declined level. We can’t be completely structure noise free image but we can improve the quality of image by estimating those noise. The proposed approach is an innovative way to estimate and remove the noise which found through observation during the processing of image. Principal component analysis (PCA) approach is followed to remove the noise by estimating it, this can be done by following one of the statistical technique which is frequently used in signal processing for data dimension reduction or for the data correlation. In principal component analysis image blocks were rearranged into vector and compute the covariance matrix of this vector. Then by selecting the covariance matrix eigen values which corresponds only to noise. With the help the average of the eigen values we can be able to estimate the noise present in the image , for estimation of noise in image we just take a partial region of the image so that it will be convenient for us to reduce it by using the denoise function.
Keywords: Image Processing, Noise Estimation, Noise Removal, Principal Component Analysis.

A Superficial Solid-State Heating Method for the Synthesis of Zinc- Oxide Nanoparticles in Polymer Matrix
Sujata Kasabe, Parag Adhyapak, Uttam Mulik, Dinesh Amalnerkar, Chetan Bhongale
Abstract: In this study, we report the simple and cost-effective in-situ synthesis of zinc oxide (ZnO) nanoparticles in polymer matrix (PPS). The polymer -polyphenelene sulphide (PPS) plays twofold role in the preparation of ensuing nanoparticles like -a) a chalcogen source and b) a stabilizing matrix. We have studied the effect of molar ratio (1:1) on the reactants- zinc nitrate and PPS. The synthesized nanocomposite were characterised by various physico-chemical techniques as X-ray Diffractometry (XRD) , SEM and UV-Visible spectroscopy. The prima - facie evidence for both type of ratio reveals subsequent entrapment of zinc oxide nanoparticles.
Keywords: ZnO; solid-state; nanoparticles; XRD; PPS.

A Review on Carrier Frequency Offset (CFO) in OFDM System
Rashi Sharma, Neeraj Shrivastava
Abstract: With the increase of communications technology, the demands for higher data rate increased quickly. OFDM is a candidate for achieving high data rates in mobile environment because of its multicarrier modulation technique, where a single data stream is transmitted over a number of lower rate subcarriers. The OFDM is one of the techniques for Parallel transmission. In this Paper, we address basic OFDM. The main attractive property of OFDM is that it’s inherently resilient to multipath reflections because of its long symbol time. However, this comes at the cost of a relatively high sensitivity to CFO. One of the major drawbacks for OFDM system is Carrier frequency offset (CFO). The OFDM systems are sensitive to the frequency synchronization errors in the form of CFO, because it can cause the ICI which can lead to the frequency mismatched in transmitter and receiver oscillator. In this Paper, a survey on CFO in OFDM system will study. The CFO causes loss of orthogonality between sub-carriers and the signals transmitted on each carrier are not independent of each other. This paper presents, CFO and the influence of Carrier frequency offset in OFDM systems.
Keywords: Orthogonal frequency division multiplexing (OFDM), Carrier frequency offset (CFO) and Intercarrier interference (ICI).

A Review on Various Technique of PAPR Reduction for OFDM Communication System
Minakshi Dubey, Neeraj Shrivastava
Abstract: Orthogonal Frequency Division Multiplexing (OFDM) is a very attractive technique for high-data-rate transmission in wireless and wired applications. One major disadvantage of OFDM is that the time domain OFDM signal which is a sum of several sinusoids leads to high peak to average power ratio (PAPR). Number of techniques has been proposed in the literature for reducing the PAPR in OFDM systems. In this paper two techniques proposed for reducing the PAPR are Selected Mapping (SLM) and Partial Transmit Sequence (PTS). This paper provides a review of various technique of PAPR reduction for OFDM communication system.
Keywords: OFDM(orthogonal frequency division multiplexing), PAPR(peak to average power ratio), SLM(selected mapping), PTS(partial transmit sequence), CCDF(complementary cumulative distribution function).

Case study of Distributive Formula to Remove Correlativity for Reducing Mean Transfer Time in Peer to Peer Networks
Jeevan Kumar Chenna, Botcha Kishore Kumar
Abstract: The Peer-to-Peer (P2P) networks are widely used for internet file sharing. In general the file download can take minutes or hours depending on the level of network congestion or the service capacity fluctuations. In this paper, we consider two major factors that have significant impact on average download time, namely, the spatial heterogeneity of service capacities in different source peers and the temporal fluctuations in service capacities of a single source peer. We show that both spatial heterogeneity and temporal correlations in service capacity increase the average download time in P2P networks and then analyze a simple, distributed algorithm to reduce the file download time. Here, we analyzes a new algorithms called that effectively remove the negative factors of the existing systems i.e. Parallel downloading, Chunk based switching, periodic switching, thus reduce the average download time. Our algorithm removes correlations in the capacity fluctuations and the heterogeneity in space, thus greatly reducing the average download time.
Keywords: Network performance, P2P networks, Peer Selection Strategy, Service Capacity.

Performance Analysis of Multilevel Converter Using Matlab
Mrs. Simmi Prajapati, Dr. Arunima Verma, Mr. Bipin Singh
Abstract: This paper deals with modern power electronic equipments related serious problems in recent years. High current harmonics, low power factor and non-sinusoidal line current are the drawbacks of the diode rectifiers and phase-controlled rectifiers. To increase the input power factor and decrease the total harmonic distortion, multilevel rectifiers and inverters have been proposed for high power and medium voltage applications because they can provide many advantages such as low voltage rating of power semiconductors and low voltage harmonics. This type of converter is suitable for high voltage and high power applications. This multilevel inverter has ability to synthesize waveforms with better harmonics spectrum.
Keywords: MATLAB Simulink, 3- level converter, Rectifier, PWM, Active power filter.

Sweta Sankhediya, Prof. Yogesh Mishra, Prof. Sachin Bandewar
Abstract: A multiplier is one of the key hardware blocks in most digital and high performance systems such as digital signal processors, microprocessors & FIR filters. With advances in technology, many researchers have tried and are trying to design multipliers which offer either of the following- high speed, regularity of layout, low power consumption, and hence less area or even combination of them in multiplier. By designing the suitable for various high speed, low power, and compact. Area and speed are two conflicting constraints. Subsequently improving speed results always in larger areas. In this review paper numerous researches have been analyzed and we try to find out the best trade off solution among the both of them. As we know multiplication goes in two basic steps.
Keywords: CSLA, CLAA, Area, Delay & Array Multiplier.
