Author :Yogesh Babaraoji Thakare

Volume, Issue, Month, Year : Vol (2), No (4), October, 2016


ABSTRACT


Small antennas satisfying bandwidth requirements in wideband, broadband and multichannel communication systems are of wide interest among researchers. This paper investigates the resonant behaviour of proximity coupled circular fractal planar monopole against circular fractal planar monopole without proximity coupling. The antennas are fed using microstripline and coplanar waveguide technique. These antennas are designed and printed on low cost FR4 substrate ( height h=1.56mm and εr =4.3) of size 110 mm by 115 mm with circular patch radius of 40 mm. The planar fractal monopole shows multiband characteristics under different configurations of feed. The monopole can be used for various compact applications in 482 MHz to 4 GHz band.

ABSTRACT


Cultural understanding and environment of upbringing plays a pivotal role in deciding right and wrong that influences our perception and decision-making. Electroencephalogram (EEG) is being employed since past several years to understand cognitive functioning of human brain. Here, we employed EEG to determine impact in cognitive functioning due to cultural upbringing. The objective was to detect if there is any influence of difference in cultural understanding related to alcohol use, on EEG obtained from alcohol consumers and non-consumers. The present study was done between Indo-Aryan and Tibeto Burman linguistic groups from Shillong Meghalaya. Embedding dimension was used to characterize EEG. The embedding dimension from the frontal and occipital regions of the brain of both alcohol consumers and non-consumers in Tibeto Burmans and Indo Aryans were determined via a MATLAB program. The results show that the embedding dimension profiles of alcohol consumers and non-consumers are quite different. For the control (non consumers) both in case of Tibeto Burman and Indo Aryans the value of the embedding dimension was higher in occipital regions as compared to the alcohol consumers. This result implies the loss of coherence and neuronal connectivity for alcohol consumers. However, this effect is more prominent in the case of Indo Aryans.

Author : Mine Seçkin and Necla Yaman Turan

Volume, Issue, Month, Year : Vol (3), No (4), October, 2016


ABSTRACT


In this study robotic hands and fingers’ materials are investigated from past to present and a sponge
robotic hand is designed for biomedical applications. Emergence and necessity of soft robotic technology are explained and description of soft robot is made. Because of the importance of hand in a person’s body, researchers have dealt with robotic hand prostheses for many centuries and developed many hand types. To mimic the best for the human limbs, softness of the hand is one of the important features. Recent studies are summarized in a table. In the table you can see materials that are used in robotic hand and fingers; they are classified as soft and rigid with their years. In literature sponge was found as the most suitable material for the fingers, but there is no study about a sponge hand. This study aims to fill this gap in literature. In this paper manufacturing of a Sponge Robotic Hand’s production parameters and stages are explained clearly. Finally advantages of sponge robotic hand and future studies about sponge robotic hand are mentioned.

Author : Gaurav Haramkar1 , Prof. Rohita P. Patil2 and Renuka Andankar3


Volume, Issue, Month, Year : Vol (2), No (4), October, 2016


ABSTRACT


In this paper, a 2.4 GHz fully integrated LC voltage controlled oscillator (VCO) for RF wireless
applications is presented. The VCO circuit is designed using TSMC 130 nm CMOS process. The circuit design is based on differential oscillator structure with cross-coupled NMOS transistors which achieves low power dissipation and low phase noise. Simulation and layout of the VCO is carried out using ADS Tool. The VCO operates from a supply voltage of 1.8 V and consumes 19.62 mW of power. After simulating the proposed design the VCO shows a phase noise of -128.68 dBc/Hz at 1 MHz offset frequency from a 2.4 GHz carrier signal. The frequency range of the VCO is from 2.36 GHz to 2.61 GHz when the control voltage changes from 0 to 2 V. The FOM is obtained as -183.73 dBc/Hz. The total chip area, including pads, occupies 0.7 mm × 0.7 mm.

Author : Gulfa Rani1 and Robinson S2

Volume, Issue, Month, Year : Vol (1), No (4), October, 2016


ABSTRACT


In this paper, iterative square ring fractal antenna is proposed, designed and developed for Wireless
application. The functional characteristics of the antenna such as return loss, VSWR, radiation pattern and gain are evaluated. Compact size and multi-band compatibility are the major design requirements of fractal antenna. The proposed antenna has the dimension of 20mm X 20mm and it supports dual band which is designed in FR4 substrate. It resonates at 5.9 GHz and 8.8 GHz with the return loss of -33dB, - 16dB, respectively. Further, the performance of the antenna is analyzed by varying feed position, feed width and substrate thickness. By the analysis, we concluded that the proposed antenna have better performance at left feed position with 0.9mm of feed width at the substrate thickness of 3.2mm.

Author : Isabelle Huynen

Volume, Issue, Month, Year : Vol (1), No (4), October, 2016


ABSTRACT


This paper presents a thorough study of the behaviour of microwave absorption occurring in lossy dielectric slabs as used for microwave absorbers. The influence of the various parameters governing absorption is demonstrated : dielectric constant, conductivity, thickness of slab and frequency. It is
shown that for several combinations of values for these parameters absorption can be maximized to up to unity, i.e. all the incident power is absorbed.

MODELING STUDY OF LASER BEAM SCATTERING BY DEFECTS ON SEMICONDUCTOR WAFERS

Author : Srikumar Sandeep1 and Alexander Kokhanovsky2

Volume, Issue, Month, Year : Vol (1), No (4), October, 2016


ABSTRACT


Accurate modeling of light scattering from nanometer scale defects on Silicon wafersiscritical for enabling increasingly shrinking semiconductor technology nodes of the future. Yet, such modeling of defect scattering remains unsolved since existing modeling techniques fail to account for complex defect and wafer geometries. Here, we present results of laser beam scattering from spherical and ellipsoidal particles located on the surface of a silicon wafer. A commercially available electromagnetic field solver (HFSS) was deployed on a multiprocessor cluster to obtain results with previously unknown accuracy down to light scattering intensity of -170 dB. We compute three dimensional scattering patterns of silicon nanospheres located on a semiconductor wafer for both perpendicular and parallel polarization and show the effect of sphere size on scattering. We further computer scattering patterns of nanometer scale ellipsoidal particles having different orientation angles and unveil the effects of ellipsoidal orientation on scattering.
