Three consecutive Coulomb excitation experiments were performed to measure the reduced transition probabilities in Te120,122,124 by using a Ni58 beam. For Te120 the collectivity was remeasured with high precision yielding a B(E2;0g.s.+→21+) value of 0.666 (20) eb22. From the B(E2) values connecting higher-lying states, the nuclear structure of Te120,122,124 was determined and shows a rotational behavior quite in contrast with the vibrational structure of the level schemes. The data are compared with different models. © 2014 American Physical Society.

In this paper a small size patch antenna with defected ground structure (DGS) is designed for emergency management applications. The microstrip fed antenna is consisting of rectangular shape partial ground plane and meander line shaped DGS is optimized. The resonant performance of the proposed antenna has been illustrated using method of moment based IE3D EM simulator. The antenna is designed to resonate at 4.94 GHz frequency and possesses the properties of good performance, compact size, low profile and low cost, therefore it is feasible for practical applications in Emergency Management. © Owned by the authors, published by EDP Sciences, 2016.

In this study red and white potato starches were treated with γ-irradiation of 0, 5, 10 and 20kGy. Physicochemical, pasting and morphological properties of the irradiated starches were investigated. Apparent amylose content, pH, moisture, swelling power and syneresis decreased; whereas carboxyl content, water absorption capacity and solubility increased with increasing irradiation dose. Pasting properties also decreased significantly (p≤0.05) upon increasing the irradiation dose. Observation under scanning electron microscope (SEM) showed surface cracking of the starch granules by γ-irradiation which increased with increase in irradiation dose. X-ray diffraction pattern remained the same upon irradiation but a decrease in relative crystallinity was observed with increasing irradiation dose. © 2014 Elsevier Ltd.

In this study, some selected physical properties of oats and barley viz seed size, shape, gravimetric properties, density characteristics, angle of repose, static coefficient of friction and terminal velocity were determined at a constant moisture content of 8.0 %. These properties are often required for designing of food processing appliances. The average of the principle diameters was found to be 4.96 ± 0.50, 5.34 ± 0.31, 6.00 ± 0.26 and 5.41 ± 0.44 mm and 1,000-grain weight was 41.9 ± 0.2, 40.06 ± 0.02, 36.66 ± 0.01 and 36.51 ± 0.02 g for hulled barley, hulless barley, Sabzaar oats and SkO-20 oats, respectively. The grains were narrow and elongated having an average sphericity of 50.55 ± 3.7, 47.923 ± 1.8, 32.578 ± 1.3 and 35.69 ± 2.1 %, respectively. The physical properties of the flours like angle of repose, flowability, bulk and true density were also determined. The value of angle of repose was found to be 50.44 ± 0.270, 63.45 ± 0.340, 46.86 ± 0.250 and 44.49 ± 0.100 for the flour of hulled barley, hulless barley, oats Sabzaar and SKO-20, respectively. The flours had poor flowability having a compressibility index of 33.69 ± 0.12, 34.32 ± 0.87, 27.94 ± 1.23 and 27.5 ± 0.74 and Hausner’s ratio 1.58, 1.52, 1.38 and 1.37, respectively. © 2014, Springer Science+Business Media New York.

High velocity contact-impact problems are of great interest in industries related to aerospace, mechanical and civil engineering. Ductile fracture often occurs in such applications. Taylor rod impact tests are used as experimental and numerical tests for determining the mechanical behaviour of materials subjected to high strain rates. At sufficiently high velocities, a significant plastic deformation leading to fracture is observed. In this paper, ductile fracture in Taylor rod made of AISI1045 steel is simulated using a continuum damage mechanics model. Simulations are performed for the velocity of 250 and 300 m/s. It is observed that, at lower velocities, tensile cracks are observed at the outer edge of the impact surface. On the other hand, at higher velocities, the fracture is observed at the central axis (confined fracture) as well as at the outer edge leading to fragmentation. Both the results are consistent with the experimental results available in the literature. Copyright © 2010 by ASME.

This paper presents an FPGA based embedded hard core IP design for real time moving object tracking system. A well known Kernel based mean shift algorithm is used for tracking a moving object in a real time scene. Implementing these systems in real time applications when there are variant target model and background illumination changes become challenging due to high computational cost and algorithm complexity. We propose the design of some application specific hardcore IPs and to identify reconfigurable hardware blocks. The hardware blocks are designed for bin calculation, kernel derivative, and weighted histogram computation functions of mean shift algorithm. These blocks are used as hardware IPs in embedded architecture and implemented on Spartan-6 IVK FPGA board. The main idea of this work is to accelerate the performance of object detection system by partitioning the algorithm between dedicated hardware and software. The hardware cost of design IPs are compared with some other tracking systems. However, identification of reconfigurable blocks is also part of this work to improve overall performance of the system. ©2013 IEEE.

This paper investigates the basic proportional integral (PI) controller for power quality (PQ) improvement using a 12-pulse voltage source converter (VSC) based high voltage direct current (HVDC) transmission system. The PI controller's parameters are selected using Zeigler Nichols approach and applied for PQ improvement during various transients. A reduced current sensor topology is used to minimize control complexity. The proposed system is designed, modelled and simulated in MATLAB-Simulink environment under various transient conditions such as load perturbation, voltage sag, tapped load fault at points-of-common coupling and single line to ground (SLG) fault at input AC mains. The obtained results are presented to demonstrate power quality improvement at point of common coupling (PCC) and effectiveness of the proposed control approach in handling various transient conditions. © 2016 IEEE.

Researchers have discovered a new way to construct an efficient battery using zinc and copper electrodes and a slice of potato. The scientists discovered that the simple action of boiling the potato prior to use in electrolysis, increases electric power up to 10 fold over the untreated potato and enables the battery to work for days and even weeks.

Feature selection is a process of selecting desired number of features from a large set of original features that purely contribute to the prediction of a test data with the help of a classifier. Many application areas such as, gene expression array analysis, test processing of internet document and combinatorial chemistry make use of feature selection, due to the presence of tens or hundreds of thousands of features in the dataset, the analysis of such a large number of feature set is impossible. Selecting relevant features increases the performance of predictor. Also, it makes the predictor accurate and cost effective. It also provides the better understanding of the process that classifies the data. In this paper, a new approach of feature selection has been proposed in order to improve the classification accuracy. The proposed algorithm has been tested on publicly available Heart Disease and Sonar data sets. © 2015 IEEE.

One of the most remarkable ability of human vision system is to recognize face. Robustness to variations in facial expressions is one of the greatest challenges in field of face recognition. Human face can have lot of variations in appearance. Face recognition system must be capable of identifying face despite these variations. This study is an effort to address the effect of varying illumination and pose conditions in face recognition. Under varying illumination and pose conditions, the face of same person appears to be different due to varying lightening and different viewing conditions. Majority of research in this field has been focused on frontal face recognition. © 2016 The Authors. Published by Elsevier B.V.
