Ghandhy College of Engg. & Tech., Surat, Gujarat, India ----------------------------------------------------------------------***--------------------------------------------------------------------Abstract The reserves of coal, oil and natural gas are diminishing day by day and it has become imperative to exploit the non conventional energy sources. The obvious choice amongst the renewable sources is the sun’s energy –The Solar Energy, as it is the cleanest of all, in abundance and an everlasting source of energy. The generation of electricity using solar photovoltaic systems is getting popular at a very fast pace. The Sun’s energy is incident on earth in the form of photons which is converted into electricity using Solar PV panels. The electrical power produced by the PV panels is dc while majority of electrical loads are running on ac. This makes the role of inverter necessary for conversion from dc to ac. Further the control of the inverter plays a major role in the satisfactory functioning of the grid connected inverters. The main consideration for the inverters for grid connectivity applications is the measurement of phase of the grid voltage and grid current and then the generation of pulses of the inverter such that the inverter voltage and current are in phase with each other. The output power quality is also one of the major considerations which needs to be matched with various international standards along with easy protection and simple system control. The control of inverter may be done by either using PLL, hysteresis current control or using a ZCD circuit. These three methods are discussed here.
Potential activity of Moringa Oleifera leaf extract and some active ingredients against diabetes in rats

Moringa oleifera has been regarded as a food substance since ancient times and has also been used for treatment of many diseases such as diabetes, hyperlipidemia and cardiovascular disease. The aim of this study is to evaluate the antidiabetic activity of Moringa oleifera leaf extract and three of its active ingredients (moringinine, quercetin and chlorogenic acid). Alcoholic extracts of Moringa oleifera leaf, moringinine, quercetin and chlorogenic acid; were tested against diabetic rats induced by alloxan. The aim was achieved via determination of glucose level, C-peptide, liver function tests, lipid profile and some oxidative stress markers. Pancreatic histopathology was also performed. Our results indicated that Moringa oleifera leaf extract counteracted the alloxan-induced diabetic effects in rats through normalization the elevated serum levels of glucose, triacylglycerol, total cholesterol, protein carbonyl content, malondi-aldehyde, total antioxidant capacity and C-peptide. Moreover, it restored the normal histological structure of the pancreas in diabetic rats. The result of our study suggests that alcoholic extract of Moringa oleifera leaf possess potent antidiabetic activity and also is a good source of natural antioxidants. Quercetin has the most potential antidiabetic activity in the extract, followed by chlorogenic acid and moringinine; the three compounds are responsible to a great extent for the antidiabetic activity of the whole extract.

A SYSTEM FOR INDOOR NAVIGATION: GUIDEIT - PERSONAL ASSISTANT

- With the increase in huge and complex indoor infrastructures, the need of indoor location-based services has risen. Traversing in an indoor structure is as puzzling as traversing in outdoor environments. Global Positioning System accurately helps to navigate in outdoor environments. However it cannot determine the accurate location within the confines of an indoor environment where the GPS signals become weak and attenuated due to a huge number of obstacles. This makes people resort to the traditional maps or floor plans provided in various places like shopping malls, university campuses. The proposed paper is set to provide an Android application which will create an indoor navigation system using step count and step detection methods and Augmented Reality (AR). Acting as a virtual guide, mobile sensors like GPS and accelerometer will be coupled while developing the application which will assist in navigating inside an indoor environment.

PAPR Performance analysis of DFT-spread OFDM for LTE Uplink transmission

: In this paper, Orthogonal Frequency Division Multiplexing (OFDM) is considered to be the optimum modulation technique to fulfill these requirements. But one of the main drawbacks of Orthogonal Frequency Division Multiplexing (OFDM) systems is the high Peak to Average Power Ratio (PAPR) value which is directly related to power consumption of the system. Discrete Fourier Transform (DFT) spread OFDM technology, also known as Single Carrier Frequency Division Multiple Access (SCFDMA), which has a lower PAPR value, is used for uplink channel in LTE cellular systems. In this thesis results from a PAPR analysis, comparing OFDMA and SC-FDMA using different subcarrier mapping schemes like LFDMA and IFDMA are presented for Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK) and 16 Quadrature Amplitude Modulation (16-QAM), 64 Quadrature Amplitude Modulation (64-QAM)digital modulation techniques.
SECURE PUBLISHER CONTENT SHARING MODEL FOR CYBER PHYSICAL SYSTEM WITH BLOCKCHAIN BASED CLOUD STORAGE

The cyber physical system in the recent years, has seen a considerable success in large-scale distributed integration environment. Security is one of the major challenge in every system in the present scenario. Publisher subscriber system is one such, where the broker involves in the process of communication and sharing of data between Publisher and its subscriber. Many literatures do not discuss about the security involved in the system. Blockchain is a state-of-the-Art concept on which our system is designed. There is no need of third party to have the validation or the certification. Participants in the blockchain need not be known each other. Existing approaches toward secure pub/sub systems mostly rely on the presence of a traditional broker network or rely on a network of (semi)trusted brokers. The Secure pub/sub system uses AES algorithm for encryption of data and Blockchain for storage. Nevertheless, security in broker-less pub/sub systems, where the subscribers are clustered according to their subscriptions, has not been discussed yet in the literature .
An Efficient Framework for Denoising of Diffusion-Weighted MR Brain Images

 Abstract : Improving the spatial resolution of diffusion weighted imaging (DWI) is quite significant and challenging task in recent days. Many researchers have made substantial attempts to face this challenge where the researchers aimed at accurate detection of elusive lesions and more faithfully solving fibre tracts of white matter (WM). In practice, signal-to-noise-ratio (SNR) restriction is the major pertain of high-resolution (HR) DWI, which is later counterbalance the benefits of high spatial resolution. In spite of the fact that the SNR of DWI data can be enhanced with the approach of denoising in the post-processing, the conventional approaches of denoising might possibly mitigate the anatomic solvable of HR imaging data. In addition, a signal bias that is caused by the non-Gaussian noise is also not possible to adjust every time. Therefore, this article presents an efficient framework for DW-MR brain image denoising that utilizes non-local Euclidean medians (NLEM) in non-subsampled contourlet (NSC) domain, which works based on multi-scale decomposition and directionality. Simulation results are tested with different kind of DW-MR images and the proposed NLEM-NSC approach shown the superiority over existing denoising approaches. Further, it is also provided that the qualitative analysis to disclose the robustness and effectiveness of NLEM-NSC method at lower strengths of noise.
A Review on the Role of Domain Driven Data Mining

- Knowledge Discovery and Data Mining (KDD) refer to the overall process of discovering useful knowledge from data. It involves evaluation and possibly interpretation of the patterns to make decision of what qualifies as knowledge and gives choice of encoding schemes, preprocessing, sampling, and projections of data prior to data mining step. KDD applications in the real world can be as diverse as the real world big databases that exist today thus it lead us to poor knowledge of rich data. Therefore, domain driven data mining (D 3 M), allow data mining and domain experts to complement each other in regard to in-depth granularity through interactive interfaces. The advantage of D 3 M over traditional KDD is that, the involvement of domain experts and their knowledge can assist in developing highly effective domain-specific data mining techniques and can reduce the complexity of the knowledge-producing process in the real world business needs. In this study, an attempt is made to identify the role of D 3 M in the business.

Energy Harvesting Alternatives for Powering Critical WSN-Based and Autonomous Monitoring Systems

Wireless Sensor Network (WSN) applications in the industry, domestic and commercial sectors are becoming quite interesting and exciting. For instance, since January 2005, major International Oil and Gas companies (IOCs) operating in Nigeria Niger Delta region have made wireless sensor network the defacto monitoring system for their vast oil and gas pipelines, oil wells and other facilities. This is because wireless technology has vast advantages over their wired counterpart. Despite the interest generated by the varied advantage of wireless sensor nodes in the oil and gas industry and other sectors, the biggest challenge lie in the limited battery energy of these tiny wireless sensor nodes. Battery energy of the wireless sensors are so limited that it will take maximum of one year to deplete and that will require massive replacements of the batteries so that the network will still be functional. This is almost impossible or very costly for a field of thousands or millions of wireless sensor nodes. This paper will examine the possibility of harvesting ambient or environmental energy sources such as RF, solar, piezoelectric, thermal etc to store and power these wireless sensor nodes so that the need for massive battery replacements will be avoided and costs saved.
A Review on Secure Auditing with Multiuser Data Sharing for Regenerating-Code-Based Cloud Storage

Cloud storage provides different kind of services to the end user such as, remotely stored maintained, managed and backup user data. Security and privacy are the major issues for remote data storage. A secure user applies access policy control mechanism to preserve the sensitivity of data. In access control mechanism, there exist ABE i.e. Attribute Encryption scheme for encryption of data. To identify whether outsourced data is corrupted or not as it is critical issue to add fault tolerance to the cloud storage. Also integrity auditing and failure reparation to the cloud storage is difficult. Regenerating codes technique gets more popularity due their lower repair bandwidth and it provides fault tolerance. In previous methods of regenerating coded data that provides private auditing may required data owner to stay continuously online to manage auditing, repairing, etc. which is impossible and infancy task. To address problem of failed authenticators in the absence of data owners, existing approach introduced a proxy. Proxy have right to regenerate authenticators. Moreover, to release data owners from online burden a novel public verifiable authenticator is generated by a couple of keys and can be regenerated using partial keys. In this research we contribute ourselves to provide multiuser data sharing in cloud. A semi-trusted proxy will get rights from the data owner to validate their data, to maintain data repairing of authenticators and coded blocks.
Comparative Grazing Behaviour Of West African Dwarf (Wad) And Red Sokoto (Maradi) Goats In Nigeria

One of the promising ways of combating poor ruminant nutrition and under-utilization of available pasture forages is studying the behaviours of grazing animals, especially goats. This is due to the fact that lack of sustainable ruminant feeding strategies contributed to the slow growth and high mortality of ruminants in Nigeria. The comparative grazing behaviour of Thirty eight goats; comprising Thirty three West African Dwarf does and Five Maradi bucks with Average Weight of 9.50kg and 15.45kg respectively, were observed in the study for a period of 6 weeks. Standard procedures were used to underscore the grazing behaviour of WAD and Maradi goats and proximate composition of the forages. The parameters measured under grazing behaviour are: grazing, ruminating, walking, drinking and resting while crude protein, crude fibre, ether extract and ash were assessed in proximate composition. Data collected were subjected to analysis of variance at P=0.05. For WAD, grazing was significantly highest 53.20 and drinking (1.40) was the least (P<0.05). While for Maradi the values ranged between 72.15 and 2.54 in grazing and ruminating respectively. Seven species of forages consistently eaten through close observation by the goats were identified and divided into forbs, grasses and legumes. The percentage selectivity of forbs, grasses and legumes for WAD ranged from 25-50%. While for Maradi, it ranged between 33.33 and 33.34%. The forages proximate analysis range for crude protein was from 6.17-23.47%, crude fibre 11.97–33.00%, ether extracts 8.50–10.50%, ash 5.50-17.33%. The study showed that breeds of goats exhibit different grazing behaviours when raised on pastures composed of different forages with varying nutrient composition.
