Earlier, during open — circuited condition of power line at receiving end side, we have only concept of Ferranti effect, which determines that open voltage, i.e. of receiving end side, of power line is always longer than close voltage, i.e. of sending end side, in case of uncompensated or smaller ohmic value of it. But, here with in this paper for the case of purely uncompensated one again over the...
Image quality assessment (IQA) plays a crucial role in monitoring quality control in image communication systems, and in benchmarking and optimizing parameters in enhancement algorithms. The full-reference IQA metrics require a good-quality reference image, obtaining which may not be practical in real-life applications. This paper, therefore, proposes a no-reference IQA metric based on the hypothesis...
Flow control is essentially a very important part of the process control industries. The flow control loops often employ pneumatic control valves as the final control element. These control valves suffer from various nonlinearities and stiction is most common of these. Due to stiction effect in the pneumatic control valves, the commonly used proportional-integral-derivative (PID) controller introduces...
This paper compares the classification capability of data acquired in hybrid and dual linear polarization mode over the Chelmsford area, United Kingdom, from RISAT-1 C-band satellite. Support vector machine based supervised classification is used in the study and accuracy is assessed over the validation pixels. The hybrid-pol RH/RV combination shows better classification accuracy over linear pol HH/HV...
This paper presents an effective design of a 2nd order infinite impulse response digital differentiator optimized using cuckoo search algorithm (CSA). In the proposed design scheme, sum of the coefficients of numerator terms was restricted to zero so as to approximate DC frequency response accurately. This restricted condition resulted in a much better approximation in terms of superior performance...
Robotic manipulators are used in wide range of industrial applications. These are highly complex, multi-input multi-output and coupled systems requiring efficient control mechanism. This complexity is further enhanced as the number of links is increased. PID control is the most widely employed control scheme in the manufacturing industry but conventional tuning approaches for tuning PID gains do not...
In this paper, a Flyback-Forward converter employing a non-cascading scheme is presented in discontinuous conduction mode. The converter is designed to enhance the duty ratio of over 50%. As a result, the flyback sub-converter acts in boost mode and generates stepped-up output voltage. Since the switch utilization is required to be as high as possible in a forward converter, in present case, this...
Cognitive Radio Network (CRN) provides a way for the improvement in the capacity and spectrum utilization with the use of idle spectrum band of licensed users (PUs). Currently, CRN has come to its upper bound limit which may restricts the progress in the area of CRN. This paper tries to take care of this issue by further exploring the idea of ‘Two Tier CRN (TT-CRN)’ by using space-time spectrum sensing...
In this work, an application of constrained genetic algorithm (CGA) based optimization approach has been explored for design of low pass and high pass finite impulse response (FIR) digital filters. To accomplish the task of optimal filter design, a novel constraint function has been proposed and integrated with the fitness function in CGA environment. CGA minimizes the fitness function under supervision...
An optimization approach to design an efficient 2nd order infinite impulse response (IIR) digital integrator (DI) is proposed using Cuckoo search algorithm (CSA). The unique feature of the proposed approach has been the formulation of the condition for obtaining ideal DC frequency response which has been attained by forcing the sum of the z-term coefficients in the denominator equal to zero during...
This paper presents a Teacher Learning Based Optimization (TLBO) approach to tune the backstepping controller for effective control of a single-link flexible-joint manipulator. To assess the relative performance of TLBO, comparative studies have been carried out with the two other popular optimization techniques namely genetic algorithm and cuckoo search algorithm. The integral absolute error was...

Synchronous with RISAT-1 and RADARSAT-2 passes, corner reflectors (CR) were mounted for the evaluation of radiometric calibration of RISAT-1 compact polarimetric SAR data. Based on the CRs response on SLC images, RISAT-1 calibration constant, PSLR/ISLR, resolution, channel imbalance and cross-talk were analyzed and compared with that of product specifications. A difference of 0.5 to 1.5 dB is observed...

The capacitive switching is frequently encountered in power systems for improving the voltage regulation profile. But, it requires special attention due to an accumulation of electrical charge. This accumulated charge after current interruption can cause a dielectric re-ignition in the switching device such as circuit breaker. When this process repeats, the interruption of capacitive currents causes...
