Abstract: Nowadays OFDM (Orthogonal Frequency Division Multiplexing) techniques are adopted by many existing or progressing wireless communication standards.OFDM’s sensing and spectrum shaping capabilities together with its flexibility and adaptivity make it the best transmission technology for CR system. Spectrum sensing helps to detect the spectrum holes (unutilized bands of the spectrum) providing high spectral resolution capability.Thus, a robust spectrum sensing algorithm for OFDM modulated signals is highly decide to implement CR when the primary signal uses OFDM modulation. Motivated by this demand,a Time-Domain Symbol Cross-correlation based spectrum sensing algorithm (TDSC method) is presented in this paper.The algorithm makes use of the property that the mean of the TDSC of two OFDM symbols is not zero if they have embedded the same frequency-domain pilot tones. We propse a new decision statistic for the signal detection based on the special feature –Cyclic Prefix embedded in OFDM signal. Further, in this paper we used to control the Transmit Power for cognitive radio.Different spectrum sensing techniques for OFDM based cognitive radio are discussed in this paper.

Abstract: Today Data Centers are critical for corporal operations, monitoring networks and keeping control over all business intelligence activities. Businesses thrive over the operations ofdata center today. Data Center systems are like building or a portion of building whose primary function is to house a computer system and its support areas. This in-turn also saves the cost estimates of the organization plus it makes high-end system easily available virtually which are not just as good as but definitely more and more efficient than the so-called physical machine.Whenever you hear talking about efficient IT-utilization in business environments, you will also hear about virtualization and its advantages over the traditional IT-models. If you want to keep the company’s IT-infrastructure up to date, you have to know about utilizing virtualization methods and implementations. Today many organizations find themselves in a situation where they have their data centers filled with underutilized hardware resources. This situation accumulates from the trend of distributed computing and client/server models starting from the late 1980s. As distributed systems and servers were cheap, at the time these solutions provided fast, cost-effective and easy to deploy IT systems. Over time these IT systems became hard to manage, complicated and distributed underutilized systems, resulting in an inefficient use of floor space and excessive power consumption in the data center. Virtualization and more specifically physical to virtual server consolidation provides a solution to these so called “server sprawls”. (IBM 2005, 2). This paper goal will concentrate on virtualization usingserver consolidation using a bare-metal hypervisor platform VMware ESXi 4.0/4.1/5.0. Thesis work will introduce virtualization using different server virtualization platforms, both commercial and non-commercial, mainly concentrating on VMware Infrastructure 3 products. In the practical part a single physical production server is consolidated into a VMware ESXi 4.0 virtual environment. Our basic objective is to help all those Poor Educational Institutions, NGOs, Orphanage Schools who actually run a zero-profit “businesses” with a noble intention and who usually have less budget on computer hardware but still desperately in need of a good Computer Center to educate their students with as equal computing experience as the wealthy institutions usually have. This paper is based on the practical implementation of the Virtual Data Center for VJTI Mumbai for educational purposes. The snaps included are taken by snipping tools to demonstrate this live.

ABSTRACT: Nowadays accidents are occurring frequently, causing demise of many people by making modest mistakes while driving (in school zone, hills area, and highways). But sometimes it may not be possible to view the signboards placed by the Highway Department to alert the drivers in such kind of places and there is a chance for accident. The advancement in the processor technology and microcontrollers has opened a new system designed to prevent the accidents caused due to negligence of drivers in seeing traffic signals alongside the road and other anomalies on the roads. So to intimate the driver about the zones and to automatically maintain the speed is accomplished by means RF technology. The main objective is to design a Electronic Display controller meant for vehicle’s speed control and monitors the zones, which runs on an embedded system and can be custom designed to fit into a vehicle’s dashboard to display information on the vehicle. This system if adopted by some state can effectively reduce the number of road accidents caused by speeding vehicles losing control of the vehicle at speed breakers or by driver’s negligence towards traffic signals. This paper presents a new design to control the speed of the automobiles at remote places for fixed time. The project is composed of two separate units: Zone status transmitter unit and Electronic Display and Control unit. Once the road-sign signal is received from the zones, the vehicle’s Electronic Display Controller Unit warns the driver, to reduce the speed according to the zone, it waits for driver’s response and reduces the speed of vehicle automatically.

ABSTRACT: Agriculture is a major source of majority Indians and has great impact on the economy of the country. In a country like India, where climatic conditions vary substantially and irrigation facilities are poor. Agriculture is timely and sufficient supply of water. Water pumps are crucial in agriculture where electricity is indeed. The frequent, low voltage supply of power to the agriculture sector has caused problems to the farmers who are spending their time monitoring the supply of power without which any progress of their work. The power supply with frequent power cuts have not only lowered the efficiency of farmers but also have led to the frustration of the farmer to give up agriculture and move to urban areas for better prospects in the globalized world. In this paper we presented a system which shows, how mobile communication can benefit millions of farmers in rural India by providing a solution for the irrigation problems caused by intermittent electrical power supply. Information is exchanged in form of messages/miscalls between the system and the user cell phones. The system is based on micro-controller and includes protection against fluctuations in power supply. For measuring time and temperature RTC DS1307 and DS18S20 are used. By using this system the hardships of farmers relating water distribution can be relieved.

Abstract: Software defined radio (SDR) is the future trend for mobile communication. A SDR is supposed to facilitate high speed multimedia application for future mobile standards. Adaptive modulation forms an integral part of SDR system with robust and high data rate capability. Here we have analyzed adaptive modulation scheme with their performance in changing channel condition. The modulation scheme studied for adaptive modulation are BPSK, QPSK 16QAM , 32 QAM ,64 QAM . Different order modulations and different coding schemes, allow to send more bits per symbol, thus gaining higher throughputs and better spectral efficiencies. But it must also be noted that when using a modulation technique such as 64-QAM with less overhead bits, better signal-to-noise ratios (SNRs) are necessary to overcome any Intersymbol Interference (ISI) and also maintain a certain bit error ratio (BER). The use of adaptive modulation gains wireless technologies to yielding higher throughputs while also covering long distances. This paper focusing on the physical layer design (i.e. Modulation), here the various used modulation type will be implemented in a single Matlab function that can be called with the appropriate coefficients. A comparison will be made in terms of SNR and BER relation.

ABSTRACT: In this work the impact of different types and numerous numbers of magnetic fields on a Newtonian biomagnetic fluid is introduced. This external force causes vortexes formation on the lower plate where the magnetic field is applied. Where the magnetic field is located shear stress increases sharply and the range of this parameter on the lower wall in FHD survey is 30% shorter than MHD. Another significant effect of applying magnetic force is increasing the amount of heat transfer. If one and seven dipoles locate below the duct, the value of Nusselt number increases 9.5% and 30 % due to the magnetization force only. In MHD analysis Nu is 2.5 times higher than simple case without magnetic force. In the other case, the increment of Nusselt number due to magnetization force of seven wires is just 20% and if the electrical conductivity of the blood is considered the Nusselt number can reach to 70% maximum theoretical Nusselt number which obtains by seven dipoles.

ABSTRACT: There are different computer programs in different tertiary institutionsforcomputingexamination results.However, beyond examination result computation, not many programs in use provide multi-level aggregated data of student population and academic progress at various stages of studentship. The need for data use to inform administrative decisions in tertiary institutions have been emphasized. Analysis of students' data and academic record can promote data-informed decisions for the purposes of better planning. The "Student Record Analysis andExamination Result Computation Algorithm"(SRAERCA) is a comprehensive solution for use in tertiary institutions. The algorithmincorporates the entire computational process related to a studentfrom admission to graduation and beyond. The algorithm is modified with the flexibility to accommodate future needs and eliminate delaysin examination result computation, preparation of examination result summaries and generation of academic transcripts. A test of resilience, accuracy and analytic capabilities of the algorithm produced expected results. The stages of computation are simple and fast. With a proper file naming system, the output files in all stages are arranged meticulously. The algorithm provides an array of output datasetthat satisfies the needs of the students themselves, the course instructor, the department, and the Faculty/College. The computational processes progressively catalogimportant statistics about student population and their academic performances to encourage data use and for future reference.Ultimately, the algorithm providesinformation and analysisfor data-informed decisions toward a more professional culture in tertiary institutions.

ABSTRACT: In this paper a new 12T-SRAM cell employing 16nm CMOS technology is introduced. The cell has separate read and write paths. For reducing the power consumption, this cell inserts a transistor for isolating the supply voltage rail from cell. This transistor acts as a power gating transistor in hold mode and feedback in active mode. Also this transistor with weakening the cell in active mode, improves the write access time and write margin. The read path of proposed cell buffers by two transistors which reduces its leakage current corresponds to the stacking effect. This cell deforms the butterfly diagram and increases the available SNM. In comparison of proposed cell with 9T SRAM and Schmitt trigger 10T (SC10T) structures shows that proposed cell has 75.5% and 4.6% higher read SNM and 25% and 20% lower write access time respect to 9TCell and ST10T cells respectively. The hold power of proposed cell is also 4.24X and 4.17X lower than the other cells.

ABSTRACT: Blend based on acrylonitrile butadiene rubber and ethylene propylene diene monomer rubber as 50NBR/50EPDM loaded with N-326(HAF) and N-774(SRF) carbon black fillers was prepared. The effect of each type of carbon black on the electrical resistivity of rubber blend was studied. The changes of the electrical resistivity of rubber blend during compression and extension were investigated. Based on the shell structure theory, the experimental results were explained from the view that external pressure induces the creation and annihilation of effective conductive paths, leading to the changes in the resistivity of blends.

ABSTRACT: This paper is introduced the impact of magnetic field on a Non-Newtonian biomagnetic fluid. The stenosis artery with porous media model is used for solving the magnetic field and fluid equations simultaneously. The lump in stenosis artery creates vortexes after it place which disrupt the vessel flow. The external magnetic field is applied to weaken this vortexes and produce uniform flow. Furthermore the magnetic field decreases the shear stress on the artery due to neutralizing the created vortex. Another significant effect of applying magnetic force is declining the pressure in this region such that ten times higher magnetic field intensity from 1011 results 8.6X and 6.5X lower maximum pressure and shear stress on artery walls respectively.

ABSTRACT: Nigeria's Niger Delta region, home to the nation's vast oil reserves but paradoxically very much underdeveloped has suffered different forms of conflict in large part due to the exploration, exploitation, production and processing of oil resources. These conflicts have not only affected the exploration processes of oil resources in the region but have also hindered human and infrastructural development in the region. Thus, it is the overarching aim of this research to understand how the incessant conflicts plaguing the region can be resolved and properly managed. In line with this aim, the research focuses on the sources, types, trends and causes of environmental conflict in the Niger Delta as well as an analysis of conflict management and resolution techniques that not only ensure safe and profitable exploration process and also human and infrastructural development in the Niger Delta.

Abstract: To evaluate genetic variation among Ethiopian lentil, laboratory experiment were conducted to screen 12 accessions of lentil (Lens culinaris M.) for salt tolerance. Seeds of 12 Lentil accessions were grown at laboratory (Petri dish) condition with different levels of salinity (0, 2, 4, and 8 dSm-1 NaCl) for 4 weeks. The experimental design was completely randomized design (CRD) in factorial combination with three replications. Data analysis was carried out using SAS software. Average germination time, germination percentage, seedling shoot and root traits, seedling shoot and root weight were evaluated. The two way ANOVA for varieties revealed statistically significant variation among lentil accession, NaCl level and their interactions (p<0.001) with respect to the entire parameters. It was found that salt stress significantly delays germination rate and decreases germination percentage, shoot and root length, seedling shoot and root weight of lentil accessions. The degree of decrement varied with accessions and salinity levels. Accessions 36120, 9235 and 36004 were better salt tolerant than the other accessions. As the result, it is recommended to be used as a genetic resource for the development of lentil accession and other very salt sensitive crop with improved germination under salt stress condition

ABSTRACT: Safe drinking water is a strong constraint to the attainment of Millennium Development Goals by 2020. The water supply coverage of 38.3% of the total population corresponds to 45 litres per person and an average supply period of 3.5 hours daily. This further explains the degree of water-stress in Ikare. Annual non-revenue of 18.3% represented $6.2 million USD which was lost to physical water loss, thus leading to gradual increase in operation ratio value of 1.05. Chlorination water treatment is cost effective for large water scheme than ultraviolent (UV) with a price index of $ 0.01 per 1m3 of water. The predicted cost for plant with 5 million m3 capacity. Increasing water supply coverage requires the reduction of non-revenue water and creates effective tariff system.

ABSTRACT: Huge information alludes to information volumes in the reach of Exabyte (1018) and past. Such volumes surpass the limit of present on-line stockpiling frameworks and transforming frameworks. Information, data, and learning are, no doubt made and gathered at a rate that is quickly approaching the Exabyte/year range. However, its creation and accumulation are quickening and will approach the zettabyte/year extend inside a couple of years. Volume is stand out part of enormous information; different properties are assortment, speed, worth, and multifaceted nature. Capacity and information transport are innovation issues, which appear to be feasible in the close-term, yet speak to long haul challenges that oblige research and new standards. We dissect the issues and tests as we start a community examination program into systems for enormous information dissection and configuration.

ABSTRACT: This research revealed that exposure of methane and/or steam to radiowave (RW) and microwave (MW) energy using copper and rhodium catalysts produced hydrogen gas. The feasible pathways of chemical reactions leading to its production are shown below; CH4 + 2H2O +MW or RW + catalyst → CO2 + 4H2 4H2O +MW orRW + catalyst → 2O2 + 4H2 The generation of hydrogen gas was true for both sources of energy whether separately or in combination. The amount of hydrogen produced using RW energy was however, greater by more than 53 % as compared to the output of hydrogen using MW energy. MW at 1,145 W power using 18.3 g rhodium catalyst yielded an average of 15,000 ppm hydrogen. Using RW energy, the same quantity of rhodium catalyst net a very high yield of 542,151 ppm hydrogen. Using 153.3 g copper catalyst, RW produced an average amount of 30,820 ppm hydrogen gas. The optimum conditions for the above reactions to move forward and yield the highest amount of hydrogen gas, were the following; methane average gas flow rates of 1.0 ml/s, average steam flow rates of 5 g/s, radiowave coil glow time of 1 minute and /or greater , for microwave, time range of 4 to 5 minutes at a power of 500 to 600 W, for RW generator, 475 kHz and a coil glow time of 1 minute and higher. In general, methane as well as, steam or in right combinations of both when subjected to MW and/or RW energy in the presence of catalyst(s) produced hydrogen gas.

In the study of cold storage, specific temperature and humidity range is required for properly storage of any food. Present cold storage capacity in India is inadequate. So to develop integrated cold chain facilities across the country is very essential. In cold storage, Insulation is used to reduce heat transfer so it is necessary to analyse and calculate heat transfer rate with temperature distribution. Steady state thermal analysis gives the correct values of the temperature which is varying with the time. We can use various types of insulating materials such as EPS, PUF, XPS, Phenolic foam, Mineral wool, Bonded fibre glass etc. but the selecting correct material is important. In this paper I have calculated the heat transfer rate and the temperature behaviour for the same object with the different materials (like EPS and PUF). Though in cold storage we see various types of insulating materials which are having different characteristics but for better explanation, methodology has been validated against the actual data obtained from Penguin cold storage situated in Pune, India Also the attempt has been made to minimize energy consumption of cold store by replacing the Expanded Polystyrene (EPS) with Poly-urethane Foam (PUF) insulation. Keywords: Cold storage refrigeration plant, Steady state thermal analysis, cold storage insulation, EPS, PUF
