Performance Analysis of Conventional Direct Torque Control Strategy for Wide Range Speed Control of Induction Motor Drives
Abstract: Decoupled control of induction motor drives is possible using Direct Torque Control (DTC) method which is very simple control approach paralleled to field oriented control. It is very good alternative for applications like traction or automobile where direct torque control is needed. But speed control from zero to rated or even beyond rated speed is required in such applications. Torque ripples, variable switching frequency and poor low speed performance are …

Native Language Identification from Spoken Indian English
Abstract: Automatic speech recognition (ASR) systems that facilitate voice based search and information retrieval have gained importance recently. While the performance of ASR systems for Indian languages have improved in the recent past. They have yet to gain wide acceptability as much as the ASR systems for English spoken by Indians. Almost all Indians learn English as a second or third language. So, the phoneme set and the prosody of native …

Covariance based Clustering for Digital Image Compression
Abstract: Traditionally clustering is done based on distance between the data points and the cluster centroids. A new type of clustering based on distance between the covariance matrices of the clustered data points was recently introduced. This allows clustering data points according to their spatial distribution model. This paper presents an improved algorithm for the computation of covariance based clustering with application to digital image compression. Karhunen-Loeve Transform is an optimal …

Direction of Arrival Estimation in Mobile Communication Systems using MUSIC Algorithm
Abstract: AbstractAdaptive antenna arrays use multiple antenna elements to form directional patterns in order to improve the performance of wireless communication systems. The antenna arrays also have the ability to estimate the Direction-of-Arrival (DoA) of the signals received from the desired transmitters as well as the directions of interference signals. The results of DoA estimation are then used to adjust the weights of the adaptive Multi-Input Multi-Output (MIMO) antenna so that …

Nonlinear Channel Equaliser using Discrete Gabor Transform
Abstract: ABSTRACTThe adaptive equaliser makes use of adaptive digital filters whose filter coefficients are modified depending on the channel characteristics at the front end of the receiver. The noise introduced in the channel gets nullified and hence the signal-to-noise ratio of the receiver improves. Discrete Gabor Transform (DGT) helps decorrelate input data because of which the convergence speed of the Mean Square Error (MSE) improves considerably. It is found that the …

Treatment Approaches in Intracranial Hypertension: A Review
Abstract: Intracranial hypertension is considered, when intracranial pressure (ICP) increases above 20 mmHg for a period of more than 5 min. A persistent rise in ICP produces compression effect over cerebral vasculature and reduces cerebral blood flow (CBF) and cerebral perfusion pressure (CPP). It results in brain stem compression and herniation, if left untreated. A systematic assessment of clinical status, serial and continuous monitoring of vital parameters and evidence based therapeutic …
