This paper presents the performance evaluation of a circularly polarized wearable antenna on flexible Ethylene Propylene Diene Monomer (EPDM) foam substrate. EPDM is a rubber based material with high flexibility, good shock resistance and easy attachment to any curved surface. The designed antenna operates for Industrial, Scientific and Medical (ISM) band and Wireless Body Area Network (WBAN) applications...
In this work, input characteristics of Quadrifilar Helix Antenna (QHA) are investigated for variations in height in the presence of finite metallic structures of varying sizes. It is noticed that the input characteristics such as conductance, susceptance and reflection coefficient are affected as height of QHA above these finite metallic ground planes varies. Rapid variations are observed if QHA is...
Electrocardiogram (ECG) is not only a vital sign of life but also contains important clinical information and even identical features. Similarly, ECG provides various significant characteristics to advocate its use as a biometric system such as uniqueness, permanence and liveness detection etc. This research provides with the complete systematic approach of ECG based person identification for general...
In this paper we describe a method of automatic motion tracking of a person in a sequence of video frames. The method is suitable for tracking a person walking or running in a surveillance video captured from a single still camera. The method initially removes noise from the captured images then segments the images using frame difference and binary conversion techniques and finally tracks the person...
Healthcare is very important factor in every body's life and Information technology. It is playing an important role in providing better health with number of advancements. Internet of things (IoT) is an emerging technology. Due to its popularity in technology and internet world, IoT is rising in every field of life and so in health sector. Health is something in which its focus is more concentrated...
Under the Advanced Metering Infrastructure, millions of metering endpoints spread over the residential areas need a two way communication network to connect them with the head-end system (HES) through a data collector. The data collector has a high bandwidth gateway to the HES but the last mile network to connect the collector with the endpoints remains a challenge. Narrow band power line carrier...
With the emergence of IOT, WSNs have become prevalent for many application areas such as smart city scenario, healthcare, weather monitoring and intelligent transport system etc. Due to their smaller infrastructure and limited energy resources, these networks are considered to be controlled and lossy networks. IP mobility management in such networks playing a crucial role for object tracking or to...
High speed Elliptic Curve Cryptography (ECC) implementations on Field Programmable Gate Array (FPGA) are highly desirable for applications requiring high speed cost effective and flexible implementations of public key cryptography. Recently, many binary ECC hardware accelerators have been presented based on the Montgomery point multiplication by exploiting the underlying parallelism of the point multiplication...
In this paper we study the effect of magnetic core in both the implant and the external reader antenna and higher operational frequency of the implant for wireless passive Intracranial Pressure Monitoring (ICP). Implant and external reader antenna are inductively coupled. ICP can be monitored through the change of implant resonance frequency or external reader antenna input impedance phase dip. We...
We analyze a two-turns antenna to provide power wirelessly to 2×2×2 mm3 cubic cortical implant. We present simulation of available power and voltage to the implant and assess the impact of a inserting a magnetic core in the antennas for further performance enhancement. We have fabricated the studied antennas and verified the simulated link power efficiency through measurement in a liquid phantom.
In this paper, axial-flux permanent magnet machine is modelled to precisely imitate static eccentricities. From the model, the effect of the non-uniform airgap permeance which arises from static eccentricities on current harmonics and torque is experimentally studied. The influence of two cogging torque minimization techniques on both signatures, in the presence of static eccentricity is also examined...
There is need to develop fault detection techniques for reliable real-time diagnosis of axial-flux permanent magnet machines as they are now widely used in a variety of applications. Thus this paper presents detection techniques for interturn short circuit in an axial-flux permanent magnet machine based on a combination of torque and current monitoring using finite element analysis and experimental...
The boost inverter topology achieves both boosting and inversion in a single stage. Various controllers have been implemented on boost inverters to obtain stable operation. However, the double loop control strategy is the most appropriate because it provides good performance under nonlinear loads, abrupt load variations and transient short-circuit conditions. The double loop control strategy was introduced...
In recent times there is a prevalence in amputations in the developing world due to lack of proper medical treatment of diseases & injuries sustained in natural disasters or war; creating a need for an optimal solution that is technically sound and is affordable. This paper discusses the available solutions in the market and then proposes a new design for prosthetic hands, incorporating the morphological...
The energy demand of residential end users has been so far largely uncontrollable and inelastic with respect to the power grid conditions. In this paper, we describe a scheme to solve multiple knapsack problems (MKP) using heuristic algorithms. Keeping total energy consumption of each household appliance under certain threshold with maximum benefit is regarded as knapsack problem. Here, we design...
With more companies investing in analytics to obtain a competitive edge in the market, decision makers require better identification of valuable metrics from among their data and to be able to interpret those complex patterns more easily. The area of data mining has been heavily invested in by the research community; however there remains a gap between the visualization efforts of this newly mined...
During in-house development of custom enterprise web based applications, a lot of reusable code is written by software developers. This code from smaller units to sub systems and sometimes even fully functional autonomous components is, at times, required in other projects due to related needs across the enterprise. In the absence of a component model based development, it becomes nearly impossible...
Any morphological abnormality or atypical group of conditions in a cardiac rhythm indicates a typical class of arrhythmias. ECG plays a vital role in diagnosis of many such cardiac disorders. Some arrhythmias including ventricular fibrillation and premature ventricular contraction can be fatal if not dealt on time. Clinical analysis of ECGs by physicians may result into an inaccurate as well as a...
Distributed Gradient Descent (DGD) is a well established algorithm to solve the minimization of a sum of multi-agents' objective functions in the network, with the assumption that the network is undirected, i.e., requiring the weight matrices to be doubly-stochastic. In this paper, we present a distributed algorithm, called Directed-Distributed Gradient Descent (D-DGD), to solve the same problem over...
A comprehensive analysis has been presented, directing to study experimentally the impact effect on multi-ply angled fabric. This paper investigates experimentally the energy absorption in altered panel structure. The low velocity impact (Charpy Impact Testing) test was done onto numerous woven fiber panels. Striking velocity, panel structure and the numbers of ply influence the test. The experimental...
