Estimation of breathing rate (BR) along with electrocardiogram signal plays an important role in patient health monitoring. Continuous monitoring of BR is often required during diagnosis of many diseases. Traditional methods like nasal air flow equipments employ cumbersome methods of BR monitoring which is not suitable for continuous monitoring. Therefore, a non-invasive method of estimation is required...
The article proposes the design of the framework for vehicular ad hoc networks (VANET) for delivery of the authentication keys with minimum delay amongst vehicles having high mobility using fog and cloud computing. We propose to introduce fog computing to extend cloud computing by introducing an intermediate fog layer between mobile devices and cloud thus producing a number of advantages. Since the...
The formal methods community has over the years proposed various formally founded specification languages based on predicate logic and set theory, typically with textual notations. At the same time the model-based engineering community has proposed often less formally founded languages such as UML and SysML, typically with graphical notations. Although the graphical notations have become highly popular...
This paper presents the design, implementation, layout and measured results of a single stage 60 GHz Variable Gain Amplifier (VGA). The VGA has been implemented in 0.13 µm SiGe BiCMOS technology with ft/fmax = 250/340 GHz. It provides a tunable gain of −15 to 7 dB. The circuit consumes 32.25 mW of power from 2.5 V supply. It occupies an area of 0.6 mm2 and it is intended to be deployed in miniaturized...
In recent years, shrinking size in integrated circuits has imposed a big challenge in maintaining the reliability in conventional computing. Stochastic computing has been seen as a reliable, low-cost, and low-power alternative to overcome such issues. Stochastic Computing (SC) computes data in the form of bit streams of 1s and 0s. Therefore, SC outperforms conventional computing in terms of tolerance...
A high-sensitivity temperature sensor based on a singlemode-multimode-polymer filled hollow core fibre-multimode-singlemode (SMHMS) fibre structure is proposed. This sensor was made from a short section of hollow core fibre filled with a high thermo-optic coefficient (TOC) polymer with a refractive index close to that of the fibre cladding, fusion spliced between two singlemode-multimode (SM) fibre...
A numerical simulation of Elastohydrodynamic Lubrication (EHL) condition is carried out for conformai contact in thrust plane slider bearing. In order to carry out the investigation, a 1D plane slider bearing is considered. The thermo-piezoviscous effect of the lubricant, the elastic deformation of the interacting surfaces and the deterministic surface roughness are considered to solve the one dimensional...
This paper present the design of rectangular grid type patch antenna especially for S Band and X Band applications. Now a day's different antenna are used for different wireless application, so different band in communication system can be conventionally served in one antenna. This is achieved by formation of grid in patch antenna. For design of proposed antenna FR-4 substrate having thickness of...
Distributed computing has turned into a reality which is capable of empowering overall population and associations to make utilization of colossal computational assets without capital interest in pay per utilize form. This new worldview permits clients who have so much computational assets to outsource their costly workloads related to computation which is in return connected to cloud as well as obtain...
This paper presents automotive product life cycle cost analysis & optimization through Value Engineering and Value Analysis Techniques. In India, automotive market is getting dynamic due to increased competition, entry of automotive giants, globalization, product pricing, etc. To sustain these factors, one has to come up with strategic way and focus must be given on defining product worth, functions,...
Exergames are video games that encourage players to do physical exercises (e.g. yoga, aerobics). While exergames provide some motivational and fitness benefits, they are limited by shallow gameplay and low-intensity exercise. This occurs because, in most existing exergames (e.g. Wii Fit), the user plays the game and exercises simultaneously. By developing exergames where gameplay and exercise occur...
In this paper, the authors has presented Antipodal Vivaldi Antenna for UWB applications. It can be extended for a purpose of the different medical applications: patient monitoring, surveillance and microwave imaging. The proposed antenna has been designed explicitly for frequencies ranging from 3.1 GHz to 10.6 GHz as primitives for UWB where it has sensed operational frequencies ranges from 2 GHz...
This paper reports the spoof surface plasmons polaritons (SSPPs) based multi-band bandpass filter. An efficient back to back transition from Quasi TEM mode of microstrip line to SSPP mode has been designed by etching a gradient corrugated structure on the metal strip; while keeping ground plane unaltered. SSPP wave is found to be highly confined within the teeth part of corrugation. Complementary...
In this paper, a SSI (Sinusoidal Signal Integrator) based control technique is proposed for a single-stage single-phase solar photovoltaic (PV) grid tied with self-adjusting capability to voltage fluctuations. This system configures a solar PV array supplying the active power to single-phase grid and connected linear/nonlinear loads. The system aims at improving power quality, eliminating grid current...
Conventional welding techniques like arc welding, tungsten inert gas welding (TIG), metal inert gas welding (MIG) etc.; causes health problems like bronchitis, airway irritation, lung function changes, lung fibrosis, asthma and a possible increase in the incidence of lung cancer due to the emission of exhaust gases coming from the traditional arc welding. In this context an environment friendly technique...
In this paper, a novel printed circuit board (PCB) antenna referred to as Multi-Stub Inverted F Antenna is proposed. The proposed antenna has enhanced radiation in the plane of PCB, as compared to traditional Inverted F Antenna. The proposed Multi-Stub methodology is verified in simulation and measurement by designing antenna at 2.45 GHz, which is widely used in portable wireless consumer products...
