Author’s Name : G.P.Dineshkumar, J.JafarAli, M.Dinesh, N.Dharungeeran

Volume 01 Issue o4 April 2014 ISSN no: 2348-3121 Page no: 1-4

Abstract— In this work, this paper address a fundamental and critical task of detecting the behavior of driving and texting using smartphones carried by users. This paper propose, design, and implement TEXIVE that leverages various sensors integrated in the smartphone and realizes our goal of distinguishing drivers and passengers and detecting texting using rich user micro movements and irregularities that can be detected by sensors in the phone before and during driving and texting. Without relying on external infrastructure, TEXIVE has an advantage of being readily implemented and adopted, while at the same time raising a number of challenges that need to be carefully addressed for achieving a successful detection with good sensitivity, specificity, accuracy, and precision. Our system distinguishes the driver and passengers by detecting whether a user is entering a vehicle or not, inferring which side of the vehicle is entering, reasoning whether the user is sitting in front or rear seats, and discovering if a user is texting by fusing multiple evidences collected from accelerometer, magnetometer, and gyroscope sensors. To validate our approach, this paper conduct extensive experiments with several users on various vehicles and smartphones. Our evaluation results show that TEXIVE has a classification accuracy of 87.18%, and precision of 96.67%.

Title : DESIGN AND ANALYSIS OF LOW POWER SRAM CELL STRUCTURE

Author’s Name : Jayabalaji.G, K.Gowri

Volume 01 Issue o4 April 2014 ISSN no: 2348-3121 Page no: 5-9

Abstract— SRAM is a CMOS ICs and it uses 8Transistor Sram to store a bit. This paper represents the simulation of different SRAM cells and their comparative analysis on parameters Power Supply Voltage. All the simulations have been carried out Tanner EDA tool. The most research on the power consumption of 8T SRAM has been focused on the static power dissipation and the power dissipated by the leakage current. On the other hand, as the current VLSI technology scaled down, the sub-threshold current increases which further increases the power consumption. In this paper we have proposed 8 Transistor SRAM or cells using MCML technology which will reduce the leakage power in SRAM cell and will control the sub-threshold current. The results of 8 transistor SRAM cell array using MCML technology in represents that there is a significant reduction in power dissipation and leakage current using MCML technology.

Keywords—8 transistor sram; mcml concept.

Title : CLOSED-FORM APPROXIMATION OF THE EE-SE TRADE-OFF OVER THE MIMO

Author’s Name : S.JothiPrasanth, S.Barathkumar, M.Pruthiv, R.Raghu

Volume 01 Issue o4 April 2014 ISSN no: 2348-3121 Page no: 18-21

Abstract— This paper proposes along with spectral efﬁciency (SE),energy efﬁciency (EE) is becoming one of the key performance evaluation criteria for communication system. These two criteria, which are con- ﬂicting, can be linked through their trade-off. In this paper, we propose a novel and more generic closed-form approximation of this trade-off which exhibits a greater accuracy for a wider range of SE values and antenna conﬁgurations. Our expression has been here utilized for assessing analytically the EE gain of MIMO over single-input single-output (SISO) system for two different types of power consumption models (PCMs): the theoretical PCM, where only the transmit power is considered as consumed power; and a more realistic PCM accounting for the ﬁxed consumed power and ampliﬁer inefﬁciency. This project proposes along with spectral efﬁciency (SE),energy efﬁciency (EE) is becoming one of the key performance evaluation criteria for communication system. These two criteria, which are con- ﬂicting, can be linked through their trade-off. The EE-SE trade- off for the multi-input multi-output (MIMO) Rayleigh fading channel has been accurately approximated in the past but only in the low-SE regime. In this paper, we propose a novel and more generic closed-form approximation of this trade-off which exhibits a greater accuracy for a wider range of SE values and antenna conﬁgurations. The theoretical PCM, where only the transmit power is considered as consumed power; and a more realistic PCM accounting for the ﬁxed consumed power and ampliﬁer inefﬁciency. Our analysis unfolds the large mismatch between theoretical and practical MIMO vs. SISO EE gains; the EE gain increases both with the SE and the number of antennas in theory, which indicates that MIMO is a promising EE enabler; whereas it remains small and decreases with the number of transmit antennas when a realistic PCM is considered.

Title : AN EFFICIENT DOUBLE EDGE TRIGGERING FLIP FLOP (MDETFF)

Author’s Name : S.Santhoshkumar, L.Saranya

Volume 01 Issue o4 April 2014 ISSN no: 2348-3121 Page no: 22-26

Abstract— An efficient double edge triggering flip flop (DETFF) for low-power and high-performance applications is presented in this paper. The aim of the DETFF is to reduce pipeline overhead. In its pulse generator, the four inverters are used to generate the inverted and delayed clock signals. The explicit pulse generator is simple and suitable for Modified double-edge triggering. However, the ﬂip ﬂop latency may be degraded due to the large capacitive loads output nodes. On top of that, MDETFF suffers from high leakage current. This is caused by a high-voltage drop across transistor. when they are off, the pulse generating stage, the sensing stage and the latching stage. The Modified double edge-triggered pulse generator produces a brief pulse signal synchronized at the rising and falling clock edges. Therefore, the conditional pre charging technique is applied in the sensing stage of MDETFF, to avoid redundant transitions at major internal nodes. As for output it only needs to be pre charged in the ﬁrst cycle and remains at its high state for the remaining cycles. Since the pre charging activity is conditionally controlled, the critical pull down path is simpliﬁed, consisting of only one signal transistor. This helps to reduce the discharging time signiﬁcantly. As such, the resulting sensing stage possesses low-power and high-speed feature.

Keywords— Flip-Flop, High-speed, Leakage power

Abstract— Most oil pumping units (OPUs) have been manual control in the oilfield. This existing oil-pumping system,a high power-consuming process, has the incapability of OPU’ structural health monitoring. In this paper, a sensor network based intelligent control is proposed for power economy and efficient oilwell health monitoring. The proposed sensor network consists of three-level sensors: 1) several types of basic sensors, such as load sensor, angular sensor, voltage sensor, current sensor and oil pressure sensor, which are the first level sensors (FLS), are used for oilwell data sensing; 2) our developed intelligent sensors (IS), which belong to the second level sensor, are designed mainly for an oilwell’s data elementary processing, main fault alarm/indication, typical data storage/indication, data/status transmission up to the third level sensor (TLS), data/status transmission between IS, and command transmission down to the OPU motor; and 3) our developed software-defined (SD) control centers with an embedded database, i.e., the TLS, are designed for hundreds of oilwells data storage/management, data processing, malfunction detection, malfunction alarm/indication, stroke-adjustment command transmission down to a specific IS for power economy and the malfunction report to the maintenance staff via global system for mobile communications (GSM) short message service (SMS). Experiment results at the Chinese Petroleum’s Changing Oilfield demonstrate our proposed sensor network based system.

Title : DATA GATHERING MECHANISMS IN WIRELESS SENSOR NETWORKS USING M-COLLECTORS

Author’s Name : S.Balavignesh,G.Mohanambal

Volume 01 Issue o4 April 2014 ISSN no: 2348-3121 Page no: 48-50

Abstract— In this paper, we propose a new data-gathering mechanism for large-scale wireless sensor networks by introducing mobility into the network. A mobile data collector, for convenience called an M-collector in this paper, could be a mobile robot or a vehicle equipped with a powerful transceiver and battery, working like a mobile base station and gathering data while moving through the field. An M-collector starts the data-gathering tour periodically from the static data sink, polls each sensor while traversing its transmission range, then directly collects data from the sensor in single-hop communications, and finally transports the data to the static sink. Since data packets are directly gathered without relays and collisions, the lifetime of sensors is expected to be prolonged. In this paper, we mainly focus on the problem of minimizing the length of each data-gathering tour and refer to this as the single-hop data-gathering problem (SHDGP). We first formalize the SHDGP into a mixed-integer program and then present a heuristic tour-planning algorithm for the case where a single M-collector is employed. For the applications with strict distance/ time constraints, we consider utilizing multiple M-collectors and propose a data-gathering algorithm where multiple M-collectors traverse through several shorter subtours concurrently to satisfy the distance/time constraints. Our single-hop mobile data-gathering scheme can improve the scalability and balance the energy consumption among sensors. It can be used in both connected and disconnected networks. Simulation results demonstrate that the proposed data-gathering algorithm can greatly shorten the moving distance of the collectors compared with the covering line approximation algorithm and is close to the optimal algorithm for small networks.

Keywords— Covering salesman problem (CSP), data gathering,M-collector, mobile data collector, mobility, movement planning, wireless sensor networks.

Title : ENDOCRINE CELLULAR COMMUNICATION BASED ON SELF-REPAIRING DIGITAL SYSTEM WITH UNIFIED RECOVERY PROCESS

Author’s Name : A.Sathish, P.M.Sandeep

Volume 01 Issue o4 April 2014 ISSN no: 2348-3121 Page no: 67-71

Abstract—Nature offers some remarkable examples of how it deals with complexity and unreliability. For example, the human body is one of the most complex systems ever known. Local failures are common, but the overall function of our organism is highly reliable. This is because of the highly sophisticated self-diagnostic and self-healing mechanisms that work ceaselessly throughout our body. If we apply the main biological principles, which provide these mechanisms, to the design of electronic systems, the result is a revolutionary new approach to implementing self-repairing systems. This system is composed of a structural layer and a gene-control layer. The structural layer consists of novel modules and their interconnections. In each module of our system, the encoded data, called the genome, contains information about the function and the connection. Therefore, a faulty module can be replaced and the whole system’s functions and connections are maintained by simply assigning the same encoded data to a spare (stem) module. Mechanism implemented in the system with a field-programmable gate array with the application of a digital clock whose status can be monitored with light-emitting-diodes.

Author’s Name : S.Kanakaraj, M.Manjula, P.Samaya Muthukumaran, S.Gunasekaran

Volume 01 Issue o4 April 2014 ISSN no: 2348-3121 Page no: 72-76

Abstract— This project aims at designing and executing the advanced development in embedded systems for energy saving of street lights with light depending resistor. Nowadays, human has become too busy and he is unable to find time even to switch the lights wherever not necessary. This can be seen more effectively in the case of street lights. The present system is like, the street lights will be switched on in the evening before the sun sets and they are switched off the next day morning after there is sufficient light on the roads. But the actual timings for these street lights to be switched on are when there is absolute darkness. With this, the power will be wasted up to some extent. This project gives the best solution for electrical power wastage. Also the manual operation of the lighting system is completely eliminated. In our project we are using LDR, which varies according to the amount of light falling on its surface, this give an indication for us whether it is a day/night time. We have placed IR sensors in both sides of the road, which can be controlled by Micro controller (AT89C51).The IR‘s will be activated only on the night time. If any obstacle crosses the IR, automatically particular light will be ON, for few seconds. In our project we use regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer. The programming language used for developing the software to the microcontroller is Embedded/Assembly. The KEIL cross compiler is used to edit, compile and debug this program. Here in our application we are using AT89C51 microcontroller which is Flash Programmable IC.AT represents the Atmel Corporation ‘C’ represents CMOS technology is used for designing the IC. We believe that our idea provides better than the existing system. In the present project street lights are taken into consideration where the above discussed factors are rectified in them. This is achieved with the help of an embedded system. By using this as the basic principle we can design centralized intelligent system for the perfect usage of streetlights in any place (Viz Village, Town) can be developed.

Keywords— LDR sensor, IR Sensor,Street Lighting.

Abstract—Increase in the usage of automobiles creates more traffic jam and the same may be a reason for the automotive accidents in an increasing manner. Traffic jam during the time of automotive accidents may be an obstacle for the ambulance to reach the desired hospital in time and also the traffic jam opposes the smooth flow of the ambulance which may lead to the loss of lives .So the obstacles for the ambulance should be reduced .The main theme behind this scheme is to provide a smooth flow of the ambulance to reach the hospitals in time and thus minimizing the expiration. The proposed scheme is fully automated, thus it finds the accident spot using a GPS system and controls the traffic signal using RF communication and provides a clear way for the ambulance to reach the hospital in minimum amount of time(so called as Golden Hour). The occurrence of the accident is sensed by a MEMS sensor which is inbuilt on board of the vehicle, which identifies the accident by the abnormal vibration in the vehicle, which notifies the accident spot to the nearest ambulance automatically using a GSM system.

Volume 01 Issue o4 April 2014 ISSN no: 2348-3121 Page no: 101-104

Abstract—This paper proposes a new type of converter called a single-phase buck–boost z-source inverter. The converter can buck and boost with step-changed frequency, and both the frequency and the voltage can be stepped up or stepped down. In addition, the converter employs a safe-commutation strategy to conduct along a continuous current path, which results in the elimination of voltage spikes on switches without the need for a snubber circuit. The operating principles of the proposed single-phase buck–boost z-source inverter are described, and a circuit analysis is provided. To verify the performance of the proposed converter, a laboratory prototype was constructed with a voltage of 60 Vrms /60 Hz and a passive RL load. The simulation and the experimental results verified that the converter can produce an output voltage, to drive the three phase induction motor.

Keywords— Buck–boost voltage, Z-source inverter, step-up and step-down frequency.

Every day it is become serious issue due to various factors, for instance rising demand, decreasing production capacity and transmission losses, etc. Now a day’s many factories are using exhaust fans and it is increasing every day. The wind energy from these exhaust fans are pass around outside and its gets wasted. This wasted wind energy is the source of the power generation. This wind source from exhaust fans are collected and compressed using a single channel. The compressed air will give the enormous flow of air to the wind turbine and the wind turbine will convert it into efficient electrical energy. Accordingly utilizing wind energy from exhaust fans be able to give additional power and it will reduce the power demand.

Abstract— Because of the gradual depletion of fossil fuel reserves, and the impact of environmental pollution on the increase exhaust emissions, and there is a need for alternative fuels and technologies appropriate anti-pollution vehicles. Crude oil prices once again show marked fluctuations. It has fluctuated wildly after touching $ 80 a barrel for, has retreated to more moderate levels in recent times. This market turmoil may give some false hope for oil pressure groups that the situation would be satisfactory – League again in this context of the crisis of fossil fuels, the importance of research of alternative fuels for internal combustion engines require important. Vegetable oils – Due to the characteristics of their presence near the diesel fuel, may be a promising alternative for use in diesel engines. The only drawback in the use of Jatropha oil as a fuel is that the emission of nitrogen oxides is more than that of diesel oil. Our project deals with the implementation of the concept of hybrid fuel to reduce the emission of nitrogen oxides and study its properties in relation to the performance of the engine. Our project process includes 1) a cross- esterification of the following [design was a small station with a capacity of 2 liters and fabricated for Transesterification crude Jatropha ] 2) Use of Jatropha Curcas crude oil as well as a mixture of varying proportions of JME and diesel in one of the improvements engine. Significant cylinder diesel in the engine performance and emission characteristics were observed for JME blended with diesel with and without Partially Stabilized Zirconium (PSZ) coatedpiston.

Volume 01 Issue o4 April 2014 ISSN no: 2348-3121 Page no: 125-130

Abstract— In this paper, the researchers propose the design of reversible circuits using reversible gates. Reversible logic is implemented in reversible circuits. Reversible logic is mostly preferred due to less heat dissipation. Conservative logic gates can be designed in any sequential circuits and can be tested using two test vectors. The significance of proposed work lies in the design of reversible sequential circuits and their equivalent circuits for maximum fault coverage. The design of Master slave flipflop and Double edge triggered(DET) using Toffoli gate and Peres gate is proposed in this literature. The design of Toffoli and Peres equivalent circuits is proposed first time in this literature, in order to achieve maximum fault coverage. The proposed Toffoli and Peres gates surpass the Fredkin gate and MXCQCA gate in terms of area, number of gates and timing. The simulation and coding is performed using cadence tool.

Keywords— Reversible logic, Peres gate, Toffoli gate, Feynman gate, latches.

Abstract—The project presents a 10-bit 30-MS/s successive approximation- register analog-to-digital converter (ADC) that uses a power efficient switchback switching method. With respect to the monotonic switching method, the input Common-mode voltage variation reduces which improves the dynamic offset and the parasitic capacitance variation of the comparator. The proposed switchback switching method does not consume any power at the first digital-to-analog converter switching, which can reduce the power consumption and design effort of the reference buffer. The prototype was fabricated in a 90-nm 1P9M CMOS technology. At 1-V supply and 30 MS/s, the ADC achieves a sequenced neighbor double reservation of 56.89 dB and consumes 0.98 mW, resulting in a figure-of-merit (FOM) of 57 fJ/conversion-step.
