Renewable energy potential in the form of wind or micro hydro are available in abundance at rural locations far away from city habitat. To harness this green energy the rugged induction generator has come up as a viable option. However, induction generator has change in reactive power requirement with change in load. This dynamic reactive power requirement is proposed to be met by a DSTATCOM and thereby achieve voltage regulation, load balancing and harmonic elimination. Further these small generators can provide full benefit to rural customers if they are connected on a grid. An autonomous rural grid with induction generators in parallel is proposed for reliable supply of power and to harness the benefits of the grid. A rural autonomous grid has been simulated in this paper using induction generators and a DSTATCOM on a MATLAB platform and study is made regarding the performance of the rural autonomous grid under linear and nonlinear loads and under varying load conditions.

Source routing techniques like Trajectory Based Forwarding (TBF) are suitable for dense wireless sensor networks (WSNs) due to their low power requirement. Though usual opportunistic coordination adds reliability to TBF, it also increases delay and coordination complexity. Alternatively, this work proposes the use of multiple cooperative relays within every single hop of a trajectory so that two adjacent forwarders do not communicate directly. While minimizing energy consumption further, this novel arrangement ensures an upper bound on delay, which is essential for delay-sensitive mission-critical WSNs. Analytical results show that the use of in-hop relays improves both energy efficiency and robustness.

This paper presents the method of design of a nonlinear deadbeat control in order to improve the transient stability of a Single Machine Infinite Bus (SMIB) power system in addition with STATCOM controller. The non-linear model of an SMIB system has been linearized using Feedback linearization technique. A novel approach of design of deadbeat control, known as Signal Correction Technique (SCT) is employed to generate an additional control signal from the dynamics of the system which is incorporated to the original non-linear system through an additional feedback loop. The additional corrected signal modifies the transient oscillations of the output of the test system to a deadbeat output. The performance of the test system with SCT based deadbeat control has been compared with the performance with nonlinear STATCOM controller. It has been observed that the proposed test system with SCT based deadbeat controller produces deadbeat response and improves transient stability significantly than the nonlinear STATCOM controller.

This paper presents a mixed sensitivity based design approach of H-infinity controller for a dc servo motor system. Frequency dependent suitable weight functions for sensitivity and complementary sensitivity transfer functionare chosen to design the controller. Synthesis of H-infinity controller is performedusing Robust Control Toolbox in MATLAB. The input output data samplesfor a laboratory based DC servomotor system are takenover a finite duration of time. The SystemIdentification Toolbox in MATLAB has been employed to obtain the plant model from the input output dataset. Fitness of the model is investigated by applying different dataset in order to achieve the best fit model. Time domain performance of the system has been observed to illustrate the effectiveness of the designed controller.

This paper proposes a unified approach for robust controller (RC) design for Electro-magnetic Levitation System (EMLS) in delta domain. Dynamic systems modelling with delta operator provides a unified framework in rapprochement between discrete-time dynamic models and its continuous counterpart at fast sampling. This property is utilised to design different classical control schemes such as PI, PD and PID in delta domain for EMLS. Generally, the behaviour of the EMLS is nonlinear and it is unstable in nature. Due to the above properties it is first linearised. The controllers are designed in delta domain such that both the physical systems of EMLS (voltage and current controlled systems) become robust subject to all parameter variations and uncertainties. The simulation results exhibit the usefulness of the proposed controller design methodology.

Segmentation of the brain MRI into its constituent White Matter (WM), Gray Matter (GM) and Cerebrospinal Fluid (CSF) is a vital task for the diagnosis of various neurological diseases. In this work, mathematical morphology has been employed for contrast enhancement of the brain T2-wighted MRI, followed by segmentation with the help of Fuzzy C-means (FCM) clustering algorithm. The proposed method has resulted in better results, both qualitatively and quantitatively in comparison to the conventional method where FCM is directly applied to the raw MR images.

In the present work, electric stress analysis is performed on a MV cable termination subjected to transient electric stresses. It is well known that stress cone is used in cable joints and terminations to relief electric stresses at the junction point of insulation and conductor screen. The high electric stress near the screen-cut zone may lead to tracking, partial discharge etc. which eventually jeopardize the operation of a power cable affecting its long-term performance. Moreover, a power cable during its period of operation is subjected to different transient electric stresses in the form of standard and non-standard lightning impulse voltages. Therefore, in this contribution, a comprehensive study of transient electric stresses of a medium voltage cable termination is performed by applying different standard and non standard lightning impulse voltages. For this purpose, a 11kV cable termination is modeled in Comsol Multiphysics Software. The transient electric field analysis is performed using Finite Element method. The stress cone deflector angle and the relative permittivity of the deflector material is also varied to obtain a best possible design that minimizes the electric stress at the insulation-screen junction of a cable termination under the application of impulse voltage stresses.

In this paper authors proposed a secured Digital Biometric based watermarking algorithm and its hardware realization by means of Field Programmable Gate Array (FPGA). The scheme focuses on the Graph Based Visual Saliency (GBVS) technique. Biometric watermarking has been introduced for validity and ultimate security of a digital media. Biometric information which is basically fingerprint is being hidden in a cover image in an efficient way such that the quality of the original information is not corrupted. The result of imperceptibility is promising; moreover several attacks were made to prove the robustness of this technique. The hardware implementation of this algorithm is provided to validate this scheme.

The paper investigates the discrimination ability of the short-wave near-infrared spectroscopy for the classification of various edible oils used in India. Spectral characterization of mustard, olive, rice bran, sunflower and soybean oils are recorded by a portable near infrared (NIR) spectrometer in the range of 250–925 nm of wavelength. Due to high dimensionality problem, principal component analysis (PCA) is used here for extracting only the significant features from the near infrared spectra. Hidden clusters in the dataset are identified by applying the principal component analysis (PCA). For classification purpose multilayer perceptron (MLP) and support vector machine (SVM) are used in this work. Moreover, classifier fusion strategy using Dempster Shafer Evidence Theory is implemented to increase the prediction accuracy. The results clearly indicate the efficacy of multiple classifier fusion technique when applied to near infrared spectrometry data for edible oil classification.
