Water pollution is one of the severe problems that have a crippling effect on public hygiene. The detection of impurities present in the water is of high priority to battle its effects. In this paper, we propose a novel method to perform detection of such impurities by exploiting the dielectric constant variations caused by its presence. We present a microstrip resonator that measures the dielectric constant (relative permittivity) of the water by means of variation in resonant frequency. The design makes use of Defected ground structure (DGS) for enhanced resonance. The electromagnetic field distribution, resonant frequency and quality factor of the design are computed and analyzed. The microstrip resonator presented here has some virtues such as simple structure, easy manufacture, low cost etc. The resonator has been simulated using HFSS 9. © 2010 IEEE.

The ad-hoc networks are the temporarily established wireless networks which does not require fixed infrastructure it is also called as infrastructure less network. Because of some flaws of ad-hoc network such as shared wireless medium and lack of any central coordination makes them more prone to attacks in comparison with the wired network. Among all the attacks wormhole attack is the most severe attack. In this attack an attacker capture the packets at one location in the network and send it two another attacker at a distant location through tunnels which is established through different ways like packet encapsulation, using high power transmission or by using direct antennas. This tunnel between two colluding attackers is virtual and it is called as a wormhole. The wormhole attack is possible even if the attacker has not comprised any hosts, and all communication provides authenticity and confidentiality. By using the various approaches for finding the solution over wormhole attack, the dynamic information of the packets could still be modified. So in order to give more robust protection in some special scenario like battlefields, which requires highly secured information? there is need of developing some secured mechanism for wormhole detection. Taking into consideration this problem the proposed scheme is developed. This paper discusses proposed works on wormhole attack along with comparison of different wormhole detection techniques in ad-hoc wireless network. © Research India Publications.

A series of discrete mononuclear lanthanide(III) complexes of L1 [Ln(L1)(NO3)2]NO3.nH2O (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Y; n = 1 for Ce; n = 2 for La, Sm, Gd and Y; n = 3 for Pr, Nd, Eu, and Tb) have been prepared by the condensation of Schiff bases with the precursor compounds namely, 2,6-diformyl-4-methylphenol, 1,5-diamino- 3-azapentane and 4,5-dimethyl-1,2-phenylenediamine. All the mononuclear complexes have been prepared in situ by the step-wise condensation from the precursor compounds. The phenolate oxygen atom of the nucleating ligand behaves as a bridging group between the metal. The complexes have been characterized by elemental analysis, IR, UV-Visible, ESI, MALDI-TOF spectra and magnetic studies. The yield of these complexes increases from lighter lanthanides to heavier lanthanides. The fluorescence studies were carried out for europium and terbium complexes. The thermogravimetry studies were carried out for Gd complex of L1 shows a two step thermal decomposition pattern at temperature ranges 300 - 450 and 510 - 620 ºC. The electrochemical studies were carried out for the Ce complex of L1 consists of a reduction wave and an oxidation wave. The results of elemental analysis of the complexes are in good agreement with the theoretical values. The complexes are soluble in methanol, chloroform, DMF, DMSO, and CH3CN. Conductivity studies reveal that all the complexes are 1:1 electrolytes. © 2015, Journal of Chemical and Pharmaceutical Research. All Right Reserved.

A more accurate and less time consuming method to determine sugar content in a sugarcane juice is proposed in this paper. The increasing use of microwaves for industrial testing is a growing demand for permittivity measurement as a function of frequency. Determination of sugar in sugarcane is an important task in sugar refineries as well as food industries. Early estimation of sugar content in cane juice also enables fixing the price for canes for procurement from the fields. The various methods to measure sugar content are IR method and chemical analysis method which consumes time. Hence we propose a microstrip resonator sensor designed at 1 GHz fundamental frequency using ADS tool which has passed experimental validation by means of Vector Network analyser. The sensor is implemented using planar technology and is more compact and is well suited for permittivity measurement. The technique adopted for the sensor is shift in resonant frequency as a function of density of sucrose content in sugarcane juice.

A low cost, flexible software antenna for ISM band is presented. The Novel antenna is proposed for ISM Band applications. Pure 100 % Cotton is used as dielectric substrate material with dielectric constant 1.6. This antenna is flexible and suitable for wearable applications. The designed antenna resonates at ISM (Industrial, Scientific, and medicine) band with a return loss of more than −25 dB. The simulated and measured results show the performance in terms of Return Loss, Radiation pattern which shows the efficiency of the proposed antenna and this flexible softwear antenna is measured in various bending environments are presented in this paper. Investigation focuses on an ordinary cotton cloth with 3 mm thickness, used as its substrate, and the patch and ground plane are made up of copper as conducting material together to form a flexible textile antenna. Proposed antenna is tested in various bending condition. Such Textile antenna designed for an ISM Band 2.45 GHz. Its radiation characteristics, return loss, gain, polarization have been examined which are the issues when it is used as a wearable antenna for medical purpose. Since it is a flexible textile antenna it bends for any condition. Observations were done for various diameter PVC pipes which is equivalent to the human body organs like arm, elbow, forearm, wrist or in the leg, ankle, knee, thigh and its resonant frequencies were noted. One of the advantages of these characteristics is once the antenna is flexible and bends in any condition then the specific absorption rate can be reduced, when this antenna is placed on the human body. © Springer India 2016.

The aim of this paper is to study the reliability of communication networks using Wiener index. Use of ICT (Information and Communication Technology) or the computer communication using electronic messaging has increased tremendously in recent years. Also the modern networks that support ICT are robust, ie., its failure due to links, routing protocols, congestion etc is rare and as result, the estimation of the overall reliability of the communication networks becomes an important problem. This paper presents the graph invariant which calculates the reliability of the communication network and presents the new network topology with maximum reliability interms of the sum of distances (hops) between every pair of nodes in the communication networks. The simulated experimentation of the proposed graph invariant for the new topology has been done and compared with existing methods. © 2012 IEEE.

In this study, the effects of diisopropyl ether (DIPE)-gasoline (D10, D20, and D30) fuel blends on the performance, combustion, and emission characteristics of a spark ignition engine were investigated. In the study a four-stroke, four-cylinder multi-point fuel injection system (MPFI) engine with an eddy current dynamometer was used. The tests were performed at speeds between 1400 rpm and 2800 rpm under the load conditions of 20 N m and 25 N m. The results obtained from the DIPE-gasoline blends were compared with gasoline fuel. The DIPE-gasoline blends produced higher brake thermal efficiency, in-cylinder pressure, and heat release rates as compared to gasoline fuel. From emission point of view hydrocarbon (HC) and carbon monoxide (CO) emissions were found lesser, whereas carbon dioxide (CO2) and nitrogen oxide (NOx) emissions were observed higher in case if DIPE-gasoline blends compared to gasoline. However, retarding the ignition timing resulted in reduced NOx emission in DIPE-gasoline blends. © 2016 Elsevier B.V. All rights reserved.

Medical diagnosis is done mostly by medical practitioner's expertise and experience. But in some cases, it may lead to wrong diagnosis and treatment. In this paper, a medical diagnosis system is proposed to predict the risk of cardiovascular diseases with high prediction accuracy. This system is built using an intelligent approach based on Principal Component Analysis (PCA) and Adaptive Neuro Fuzzy Inference System (ANFIS). This system has two stages: In the first stage, dimension of heart disease dataset that has 13 attributes is reduced to 7 attributes using PCA. In the second stage, diagnosis of heart disease is conducted using ANFIS. In ANFIS, the learning capabilities of neural network and reasoning capabilities of fuzzy logic is combined inorder to give better prediction. The heart disease dataset used is Cleveland Heart Disease dataset provided by the University of California, Irvine (UCI) Machine Learning Repository. The obtained classification accuracy using this approach is 93.2%. © 2013 IEEE.
