Rampant power theft at the low voltage consumer end is a growing concern for the power distribution companies. This paper proposes an effective method for detection of power theft at low voltage consumer end. The proposed method is designed to reliably detect hooking in service line cable and bypassing of electric energy meter. In this method, a low magnitude, high-frequency, non-interfering signal...
The paper proposes a novel method for health monitoring and early stage fault diagnosis of IGBT by analyzing the electromagnetic radiation (EMR) pattern. The main cause behind IGBT failure is the evolving stress due to thermal cycle. The change in the operating characteristic of IGBT affects the EMR signature. The paper establishes the relation between different IGBT characteristic with EMR pattern...

Optimizing the energy consumption and achieving the network wide load balance for longevity operations of the network are prime issues in the mobile ad-hoc networks. we present a new approach to optimize the energy consumption and achieved the network wide load balance among nodes using non-demonian sorting generic algorithms-II. The routing constraints for energy consumption and load balancing and...
A large number of individuals lost their lives on streets each year. Approximately 1,275,000 people are genuinely injured consistently. In order to avoid critical accident on the road, there is a need of communication between the automobiles which are running on streets, cities or national highways. The design of the cars are inefficient and insecure to prevent the collisions. The revolutionary technology...
This paper presents a 3-FET stacked K/Ka-band class-AB power amplifier (PA) implemented in the GLOBALFOUNDRIES 45nm SOI process that is particularly optimized for future high-performance energy-efficient 5G mm-Wave transceiver front-ends. With a 2.9V power supply, the PA achieves 13.1dB power gain and a saturated output power (Psat) of 16.2dBm with a maximum power-added efficiency (PAE) of 41.5% at...
In this paper our work investigates the performance of Intra-WBSN by placing the Body Node Coordinators (BNCs) at different positions in Intra-WBSN. Physiological data is collected by bio-sensor nodes and forwarded to BNC through intermediate node or forwarder. The forwarder node is selected on the basis of cost-function. Cost-function depends on the residual energy of node and path-loss between sensor...
Intra wireless body sensor network (Intra-WBSN) is typically a short range wireless health monitoring network, consists of wearable or implant bio-sensor nodes which collects the patient's physiological signals and forward to patient monitoring systems. Network lifetime maximization and energy efficiency of the network have significant attention for current research. Recently cost-function based multi-hop...
In this work, microgrid is modern small scale power system of the centralized electricity for a small community such as villages and commercial area. Microgrid consists of microsources like distribution generator, solar and wind units, etc., and different loads. In the microgrid, the energy management system (EMS) having a problem of Combined Economic Emission Dispatch (CEED) and it is optimized by...
This paper proposes a simple and novel switchable microwave filter. The proposed filter can easily be switched between high pass and low pass responses. The filter uses a structure which can be easily switched. The high pass filter uses an interdigital structure and the low pass filter uses the hairpins that are mounted on the interdigital structure. The filter is reconfigurable and small in size...
In this paper an ultra wideband bandpass filter with reconfigurable notches has been presented. It consists of a reconfigurable E to C shaped resonator centrally loaded on a multiple mode resonator (MMR). The MMR is constructed using stepped impedance resonator. Two notch frequencies are created by using reconfigurable E to C shaped resonator in order to reject these two interfering frequencies. Reconfigurability...
A compact dualband bandpass-to-bandstop tunable filter based on short stub loaded stepped impedance resonators is designed. It uses pin diode for bandpass-to-bandstop filter transformation and varactor diodes for tuning of the center frequency. The filter is designed on Taconic RF-35 substrate to obtain two close dualbands with tuning of center frequencies in the range 1.66–1.88GHz and 1.98–2.29GHz...
Designing of a new routing algorithm for mobile ad hoc networks (MANETs) is a prime and essential issue due to arbitrariness in nodes connectivity and limitation of battery power. The nodes are equipped with limited powered battery and have to be use in efficient manner in order to avoid early demise nodes. In this paper, we present a state-of-the-art design for a new energy efficient geocast routing...
Vehicular Ad Hoc Networks (VANETs) have developed as an emerging technology for intelligent transportation with a number of applications that may have significant impact on the society. VANET provide comfort and safety message to the people in the vehicle itself in traffic jam as well as in the disaster prone areas. Health monitoring through VANET is one of the emerging applications under information...
The growth of population now a day is resulting in immense pressure on healthcare service. Population residing in remote areas such as villages are devoid of good health check-up facility. Therefore, it is utmost necessary to make it accessible to them. In this paper, we have introduced a basic Wireless Body Sensor Network (WBSN) consisting of sensors that can collect the physiological data of a person...

In spite of regular usage of internet in our daily lives, we are yet to receive highly incessant internet connection while travelling from one location to another. This occurs as a result of frequent handoffs between base stations of cellular networks. A high throughput Internet access protocol (HTIAP) is proposed in this paper in order to provide uninterrupted internet connectivity to the mobile...
The high cost of conventional surface acoustic wave (SAW) devices limits its widespread use as micro-sensor and actuator for lab-on-a-chip applications. Solution-processed, inexpensive SAW device based on poly[(vinylidenefluoride-co-trifluoroethylene] [P(VDF-TrFE)], a ferroelectric polymer, is an alternative route to address this issue. However, incompatibility of P(VDF-TrFE) films with photoresist...
