Power system congestion is a major problem for independent system operator (ISO) in a deregulated environment as it violates system security and cost. So it is an important task for ISO to maintain congestion free power system. In this paper generator rescheduling technique has been adopted with incorporation of wind farm in the system. Present work is three folded. Firstly location of wind farm is selected based upon power transfer distribution factor (PTDF). Secondly generator sensitivity factor (GSF) has been determined to reduce number of participating generator in congestion management. Thirdly selected generators have been rescheduled using Artificial Bee Colony (ABC) optimization techniques to mitigate transmission congestion. The proposed method is applied on IEEE 39 bus New England test system.

In this work, target design is ALU. To achieve reduction in IOs power we are searching the most energy efficient LVCMOS(Low Voltage Complementary Metal Oxide Semiconductor) IO standard, whose power consumption is less in compare to other IO standard. There is 85.18% power reduction when we migrate from LVCMOS33 based ALU design to LVCMOS12 based ALU design. There is 41.45% power reduction when we migrate from LVCMOS33 based ALU design to LVCMOS25 based ALU design. Target FPGA family is 28nm Artix-7. Verilog is hardware description language used for design of ALU. There is 7.16% reduction in power for only LVCMOS15, when we change drive strength from 16 milliAmpere to 8 milli-Ampere. There is 5.44% reduction in power for LVCMOS18 when we change drive strength from 24 milliAmpere to 8 milli-Ampere. LVCMOS33 is the highest power consumer and LVCMOS12 is the lowest power consumer among the different available LVCMOS IO standard when there is common drive strength applied.

Earth's surface consists of land features such as vegetation, soil, water, etc. Modeling of the earth's surface requires identification and understanding of the dynamics of land features. Analysis of land feature dynamics would reveal the changes that occur due to human induced activities or natural phenomenon. This plays a major role in providing up-to-date information of the natural resources. Data acquired remotely through space-borne sensors at regular intervals in visible and microwave bands aid in spatial mapping of the land features. Data acquired in visible and IR (Infrared) bands have been used for land use and land cover analysis. However, these data fails when there are cloud cover due to non-selective scattering. In this context, RADAR remote sensing would be useful as it provide information during all seasons due to long penetration properties. In present study, RADARSAT-2 single polarized HH (i.e., Horizontal to Horizontal with C-band) has been used to derive land features with spatial extent. Radar data interpretation and analysis is considered challenging and have both advantages and disadvantages in land use feature extraction. This study assess the performance of classification algorithms (Gaussian Maximum likelihood classifier (GMLC), Neural network classifier, Decision tree classifier (DTC), Contextual classification using sequential maximum a posteriori (SMAP) estimation for feature extraction using multi-temporal single polarized RADARSAT data, texture extracted data and fused data (optical sensor -LANDSAT ETM+ with SAR data). Accuracy assessments suggest that fused data perform better with all algorithms.

The grid integration of Distributed Generation (DG) is considerably increasing in recent days in order to meet the ever increasing electricity demand and reserve the fossil fuel resources. The purpose of the present work is to analyze the network performance with optimally sized Wind Turbine Generator System (WTGS) based DG units with random wind velocity variations. In the present work, three DG units are integrated in the Radial Distribution System (RDS) simultaneously. The grid integration points of DG units are determined using Maximum Penetration Ranking. The sizing of DG is carried out by optimizing a multi-objective function formulated using Goal Attainment Method. The solution of the multi-objective function is obtained employing Particle Swarm Optimization (PSO) technique. The network performance is evaluated by varying the stator connection of WTGS based on wind speed and also by varying the network parameters. The analysis is carried out in a 25-bus radial distribution network considering different wind velocity patterns.

This paper presents the scalar control as well as direct torque control for speed control of induction motor. The scalar control is an easy to implement but it gives poor dynamic response. In addition to the scalar control the space vector pulse width modulation (SVPWM) is used for effective utilization of the dc-link voltage i.e. SVPWM is having the good voltage regulation and reduces the considerable harmonics in voltage as well as current of the inverter. The dynamic response of the induction motor is improved using direct torque control with SVPWM technique. The performance of induction motor with scalar control and direct torque control is simulated in the Matlab environment and compared their response under similar operating conditions. The dynamic performance, the speed regulation, THD in the current, and the torque distortion of induction motor are effectively improved with direct torque control (i.e. lesser transient time) even while applying the load in comparison to scalar control.

In this paper, we have proposed proactive approach for fast-handoff using Access Point (AP) in Vehicular Ad-hoc Network (VANET). The existing schemes are based on context transfer for fast hand-off, but needs to reduce the latency of hand-off for VANETs. Fast hand-off in vehicle scans only the selected AP at any instance of time depending upon the association pattern. The Fast Hand-off Algorithm using AP Graph with Multiple Vehicles for VANET improves the re-association latency and context transfer process must be separated from reassociation process. From experimental and simulation results, we find that the use of AP graphs reduces the handoff latency due to re-association process and that the effectiveness of the approach improves dramatically as user mobility increases. The context transfer process for proactive fashion is used for fast handoff and reducing the context transfer latency of handoffs. The Inter-Access Point Protocol (IAPP) protocol is called the context transfer protocol.
本文提出了一种利用车载自组织网络(VANET)中的接入点(AP)实现快速切换的主动方法。现有的方案是基于上下文传输实现快速切换，但需要降低vanet的切换延迟。根据关联模式，车辆中的快速切换在任何时间只扫描选定的AP。基于多车辆AP图的VANET快速切换算法改善了重新关联延迟，并且上下文传输过程必须与重新关联过程分离。从实验和仿真结果中，我们发现AP图的使用减少了由于重新关联过程引起的切换延迟，并且随着用户移动性的增加，该方法的有效性显着提高。主动方式的上下文传输过程用于快速切换，减少切换的上下文传输延迟。Inter-Access Point Protocol (IAPP)协议被称为上下文传输协议。

A new sensorless method for 8/6 Switched Reluctance Motor is presented in this paper. Inductance of two adjacent unexcited phases are used to generate two orthogonal vectors and are used for rotor position estimation. Inductance of unexcited phases are estimated from current slope resulting from pulse injection. This method can estimate rotor position from standstill to high speed without any prior knowledge about magnetic characteristics of Switched Reluctance Motor. As this method uses only inductance of unexcited phases, saturation will not affect the estimation accuracy.

Spin Transfer Torque-Magnetic Tunnel Junction (STT-MTJ) has some unique and attractive properties like non-volatility, scalability, very low access times, etc. Moreover, the critical switching current of STT-MTJ is found to reduce, as the device scales down. Nowadays, the semiconductor industry is unable to follow the Moore's law as miniaturization of CMOS is nearing its limit due to the enormous increase in leakage currents. Hence, STT-MTJ with better features has the capability of replacing conventional CMOS transistors in the future. In this work, we design a reconfigurable full adder using the majority logic, which can act as an ALU. For this, we design a sum generator and a carry generator using MTJs and CMOSFETs. CMOS transistors switch the mode of operation of the sum generator and the carry generator from writing phase to reading phase and vice versa. During writing phase, input current pulses pass through MTJs which change MTJs' magnetization direction. During the reading phase, based on MTJs' magnetization direction, the output logic is interpreted. We show that, the full adder can be reconfigured to perform various arithmetic and logical operations. Our proposed reconfigurable spintronic ALU, can perform arithmetic operations like addition and subtraction, and various logical operations like AND, OR, NAND, NOR, NOT, XOR and XNOR using which a non-volatile digital system can be realised.

In this work, the issues of on-line adaptation for real-time applications are addressed. In such systems, unsupervised adaptation has to performed with a very small amount of adaptation data. Furthermore, in such tasks, the computational complexity involved should be as low as possible to keep the system latency in check. To address both these issues, a model interpolation based fast adaptation procedure, employing speaker cluster models as bases, is presented in this work. It is observed that the acoustic clustering of the training speakers to derive the bases greatly reduces the complexity in comparison to the techniques which employ speaker adapted models as bases. Apart from this, a KSVD based acoustic clustering scheme is also proposed. Acoustic clustering in supervised as well unsupervised mode is explored in this work. The proposed on-line adaptation procedure employing the KSVD clustering, is found to result in a relative improvement of 6% in WER on an LVCSR task.

Transient Enclosure voltage is special case of very fast transient over voltages which occurs due to disconnect switch operation or earth ground. Transient Enclosure Voltage appears on external of earthed enclosure of Gas Insulated Systems. Despite of proper grounding, this phenomenon indicates presence of high potentials on Gas Insulted System enclosures so the grounding system impedance is thoroughly examined and designed. In this study EMTP Software is used for analysis. Simulation was done by varying the different parameters. Variations of waveforms of the Transient Enclosure Voltage with various parameters have been studied.
