This paper presents, a rotor speed and stator resistance estimation under very low speed operating region using parallel rotor speed and stator resistance estimation scheme. This scheme is an extension of rotor flux based model reference adaptive system (MRAS) scheme. In this scheme the rotor speed and parameter variation is estimated using MRAS technique. The estimated speed is incorporated as a feedback to the space vector modulation based direct torque and flux control (DTFC-SVM) of induction motor drive (IMD). The rotor flux based MRAS method unable to provide satisfactory performance under parameter variation whereas this scheme can cope with the parameter variation and able to provide satisfactory performance. In order to show the effectiveness of the proposed method, it is simulated in MATLAB/SIMULINK environment. The performance of the IMD is simulated under various operating situations.

Reliability is among one of the most accountable issues in the power industry today. Power failure is the main outcome, results from continuous and wide spread use of electricity. Thus, reliability has emerges as one of the important phenomenon need to be considered. Quantitative analysis of power systems reliability can be obtained by reliability indices. Various methods are introduced and developed over the time to evaluate reliability indices of the system and thus reliability assessment of power system. This paper analyses the main distribution reliability indices (SAIDI, CAIDI, SAIFI, CIII, and CAIFI). The values are calculated in real time for rural area. Conclusion is drawn on the basis of determined values. Indices so obtained are helpful in future planning of power system.

A Kalman Estimation method which is used to estimate the position of an occluded object has a large error caused due to noise. In an occlusion, the work below proposes an algorithm with a proper Altering mechanism which could handle an occlusion with less error. As a result, the proposed algorithm could be used to handle much larger occlusions.

Specific algorithm simplifies the critical hardware requirement for smart signal processing applications. HASPA is such supervised ANN learning algorithm that specifically designed for multiple antenna based RADAR signal processing. The algorithm is based on the principle of spatial hearing of the Human Auditory Signal Processing System. In the processor, received signal from multiple sources are converted into compatible format and then suitably compared with themselves and with restored training sources. From the output data of the processor, different conclusions are made about the signal sources. The algorithm has been implemented in three steps with Linux Ubuntu based FORTRAN media and tested with the received signals of multiple antenna based tracking system. Test procedure and results have been presented and found to be satisfactory.

Back Surface Field layer plays an eminent role for both single and multi-junction solar cells for controlling the recombination rate. In this work multi BSF layers are used at both top and bottom cells to get higher efficiency. The work is done taking double junction InGaP/GaAs Solar cell and augmentation of the BSF layers is done using mathematical numerical modelling with Silvaco simulator. The structure, photo-generation rate and thickness of the BSF layers is discussed in this paper. For this improved cell schematic, the enhanced available short circuit current density is 17.35 mA/cm2 which is obtained at an open circuit voltage of 2.69 V, which leads to an augmented transformation efficiency.

The Most of affordable daily glucose monitoring techniques in diabetic patients are invasive requiring sample of blood. Microwave sensor can nondestructively measure parameter inside volume. This property suggests that microwave sensor would be well suited for noninvasively measuring blood glucose concentration in human being. After fabricating microwave based noninvasive sensor, at primary stage this sensor is tested with aqueous glucose. A Planar Microstrip Ring Resonator is designed, simulated and implemented to resonate at 1 GHz. Dielectric material is placed above a Microstrip ring resonator. Because of this near field of resonator gets interact with a Material Under Test (MUT) and electrical characteristics of resonator change in relation to the permittivity of the material. Change in the dielectric causes corresponding shift in resonating frequency of Microstrip Patch Antenna. This relationship can be useful to measure Blood Glucose Concentration level. Vector Network Analyzer is used to measure the shift in resonating frequency. The design procedure is described here and experimental results are reported.

The throughput-reliability tradeoff (TRT) for MIMO and co-operative systems are first proposed and studied under Rayleigh fading assumptions. While the interplay among signal-to-noise ratio, transmission rate and outage/error probability for MIMO and co-operative channels have been explored, those corresponding to many practical scenarios are still wide open. In this work, we deal with the TRT analysis of MIMO systems with generic distribution for channel coefficients that includes many known models as special cases.

In this paper an examination has been performed for the upgradation of transient stability limit in two area multimachine power system using different FACTS devices. The simulation of two area multimachine power system including FACTS devices has been carried out in the MATLAB Simulink domain. The performance of unified power flow controller (UPFC) for the upgradation of transient stability limit has been investigated along with other FACTS devices such as static synchronous compensator (STATCOM) and static synchronous series compensator (SSSC) respectively. The paper establishes the superiority of UPFC over STATCOM & SSSC.

A high speed and power efficient synchronous counter is proposed using True Single-Phase Clock (TSPC) based Toggle Flip-Flop (TFF) with the Extended True Single-Phase Clock (E-TSPC) based combinational logic embedded in it. The principle of realizing both synchronous up and down counter at both positive and negative edges using these flip-flops are discussed. Also gray counter is accomplished using same principle. It has been designed in 0.18 μm CMOS process under 1.8 V power supply. The simulation results show that an eight bit synchronous counter can operate at clock frequencies upto 4.54 GHz with the power dissipation of 0.67 mW, while an eight-bit asynchronous counter can operate at clock frequencies upto 5 GHz with the power dissipation of 0.5 mW.
