The random nature of network topology is a major challenge while developing new routing protocol for Opportunistic Networks (OppNets). Additionally, other factors like intermittent connections, limited bandwidth etc. further restrict the performance of existing routing protocols. In this paper, an advanced context aware routing protocol called GAP is proposed. The proposed protocol efficiently combines...
In this paper, the model order reduction methodology using novel moment matching technique is presented. A typical problem having stable operation is reduced using proposed MM technique. The reduced order model presents the unstable response. A technique of pole placement is proposed for making such unstable systems to be stable reduced models using MM technique. The comparative study between stable...
One of the major consequence of diabetic disease is diabetic retinopathy (DR), which effect on retina of diabetic people and the critical phase of diabetic retinopathy can lead to permanent vision loss. The early detection and monitoring of diabetic retinopathy is important to prevent it or for effective treatment, but the problem associated to early detection of DR is very minor changes on retinal...
Congestion management process is very crucial and important for better planning and successful operation of electrical power system. Due to increase in load, power flow for the system must be calculated to ensure system stability and security. In this paper Congestion management is implemented by minimization and optimization of loads. Use of FACTS devices is also included for optimal power flow for...
Opportunistic networks (Oppnet) are challenged networks in present wireless communication scenario. These networks are mainly applied to situations where a persistent end-to-end path between the source and the destination does not exist. Delay/Disruption Tolerant Networking (DTN) is mostly used to solve this end-toend path problem in such networks. Many routing protocols have been proposed in literature...
In this Paper, issues related to substrate coupling in system on chip design are described and demonstrated including the physical phenomenon responsible for its creation, coupling transmission mechanism and media, parameter affecting coupling strengths and its impact on mixed signal integrated circuits. A test chip to find out various aspect of mixed signal interference is planned in 0.8pm N well...
Efficient utilization of renewable energy sources (RES) is one of the major concern in present power sector scenario which can satisfy the energy requirements of an area in proper and sustainable manner. The efficient utilization of RES helps to reduce the total cost of energy generation. The main objective of the present work is to examine the efficient utilization of different modes of RES like...
Telemetry is used for sensing and measuring of information at some location and then to transmit to desire location. It is very useful for medical monitoring too. The electrical activity of heart is measured in the form of electrocardiogram (ECG) at skin. The monitoring of fetus ECG(FECG) is important to monitor the baby inside mom abdomen. The observation during labour and delivery is done by monitoring...

The System Operator (SO) is an authority responsible for the secure operation of the power system and in this way, the SO has to obtain or procure some services that maintain a balance between generation and demand in any electricity market environment. These services are termed as an Ancillary Services (AS). Therefore the management of all these services are considered as a specific function of the...
Inderegulated environment, Ancillary Services (AS) plays a vital role, as they are required for reliable and secure operation of the power system. Operating Reserve (OR), as one of the main AS, is a capability of a power system to prevent any unexpected imbalances caused by generation or transmission outage has been considered in this work. This paper considers a flexible disaggregated energy and...

The MANETs and UAV networks would soon replace existing Wireless technology due to its ease to deploy and bare minimum infrastructure requirement and dynamic topology. Emergence of vast high speed hand-held mobile devices, mail delivery drones, drone camera footage of a live cricket match etc, have reserved MANETs/UAVs in the reach of a common man. Therefore, it is imperative to address ubiquitous...
A fully dynamic latched comparator has been designed to meet the requirement of high speed and low power consumption. Such comparators are used in high speed data converters. In this work, dynamic comparators are designed in two different technologies and compared on the basis of delay, offset voltage and power consumption. These comparators work on the concept of charge sharing. Main focus is given...
In today's world everybody seems to be so much preoccupied that there is no time to think about other people. We forget about the differently abled people, the difficult task that they face in doing day to day activities .This is all because today's world doesn't care about them. Nothing here is designed for them. So thinking of those people here is a technology that will help them and us also to...
Cloud computing is very popular in organizations and institutions because it provides storage and computing services at very low cost. However, it also introduces new challenges for ensuring the confidentiality, integrity and access control of the data. Some approaches are given to ensure these security requirements but they are lacked in some ways such as violation of data confidentiality due to...
This paper presents the design of PLL (Phase Locked Loop) using PFD (Phase Frequency Detector) based on 22 transistors TSPC (True Single Phase Clock) D-FF (Flip Flop), Tri-state charge pump (CP), passive loop filter of first order and five- stage CS-VCO (Current Starved VCO) circuit. In such design, large VCO gain with increased lock range from (357MHz–900MHz) and reduced lock time is achieved using...
WSN is an application specific network. There is no general optimized solution for WSN problems. It depends upon application, resource availability. Structural health monitoring (SHM) using wireless sensor networks has drawn considerable attention in recent years. It is an active area of research that can autonomously and proactively assess the structural integrity of buildings, bridges, tunnels,...
In this article, the performance of a 20 kWe open top downdraft biomass gasifier has been modeled using EQB computer code. EQB program, consists of six modules (i.e., fluid flow, heat transfer, drying, pyrolysis, and oxidation and reduction reactions), has been used to describe physical and chemical processes of downdraft biomass gasifier. A brief description of EQB, its strength and limitations are...
An empirical modeling for dual fuel engine operated on producer gas and pilot diesel fuel has been presented to predict the performance of dual fuel engine.
