This paper presents a single-source equivalence formulation to solve for the scattering from composite dielectric objects. In the proposed formulation, all regions of the composite dielectric object are replaced by the surrounding free space medium and an equivalent electric current density on their boundary. Since the formulation only uses a single equivalent current source, it requires 4 times less...
We report a circular-shape monolithic transistor-antenna (trantenna) for high-performance plasmonic terahertz (THz) detector. By designing an asymmetric transistor on a ring-type metal-gate structure, more enhanced (45 times) channel charge asymmetry has been obtained in comparison with a bar-type asymmetric transistor of our previous work. In addition, by exploiting ring-type transistor itself as...
In recent scenario, the hardware design is becoming a very complex task because programmable hardware like FPGA has become complex with regards to the increasing number of transistors. In this paper, an overview of tool for model based hardware design is mentioned. This tool enable to describe an algorithm in a model based description without going in to complex low-level VHDL or Verilog description...
This paper presents a surface formulation to calculate the impedance of 3D interconnects with arbitrary cross-section under the magneto-quasi-static assumption. The proposed formulation combines the 2D differential surface admittance operator for conductors of arbitrary shape with the electric field integral equation to calculate the impedance. The proposed formulation avoids any volumetric discretization...
VANET consists of road vehicles each equipped with wireless communication device to provide road safety. Vehicle can transfer disseminate information using VANET services to all vehicles travelling over a geographical area with high reliability and low delay. We propose Contention Window (CW) based design mechanism that acts as segmentation based data dissemination protocol to maximize throughput...
Cloud computing is new era which satisfy user in different ways through internet. Mainly three main services provided by Cloud-SAAS, PAAS & IAAS. Lots of research is carried out on Infrastructure, because all consumers require satisfactory allocation of requirement on cloud. Many such requirements needed for a job to be executed by resources that are available to achieve optimal performance, Minimum...
Wide torque-speed range and high reliability are the primary need of the traction motor in electric vehicles. Switched Reluctance machine (SRM) offers numerous advantages such as simple and robust construction, high speed and high durability, low cost, and fault tolerance control capabilities, high reliability as each phase works independently. In view of this, the paper describes the design methodology...
This paper presents the analytical Modeling of Switched Reluctance Motor(SRM) based on the data obtained from Finite Element Analysis(FEA) tool Ansys Maxwell. Once the design of the machine is done in FEA tool then before manufacturing the actual machine it is necessary to test its dynamic performance. Testing of dynamic performance involves the operation of the motor with different control strategy...
This paper presents the performance analysis of simultaneous AC-DC power transmission scheme under balanced and unbalanced loading conditions. Simulation and experimentation based verification of simultaneous AC-DC power transmission scheme is already discussed in detail in literature. However, available literature dose not discuss the performance of this scheme under different load conditions which...
Mainly in more electric aircraft (MEA) electric power capacity is increasing rapidly. And so due to the advent of electric power system (EPS) all pneumatic, hydraulics & bleed engines are removed. Hence the consumption of fuel is reduced. Disturbances caused by various components in electrical system can inject harmonics into the system and thereby Transformer Rectifier Unit (TRU) is used for...
We have considered the baseline distribution as Bernoulli and Multinomial distribution. We studied them for the maximum likelihood estimation and also for their credible bounds. Further we illustrated by taking real data and also compared with the simulated data.
Professionals who work with children and adolescents who have developmental disabilities will find themselves working with a number of other professionals on various “teams.” These teams are typically composed of practitioners from more than one discipline working toward the single goal of providing comprehensive patient care. Research on medical and psychosocial teams confirms the overwhelming importance...
Neural tube defects result from failure of neurulation during the early development of the central nervous system. Although any segment of the developing CNS can be involved, most cases affect the lumbosacral level. Multiple factors have been identified that increase the risk for neural tube defects. Dietary supplementation with folic acid has been shown to reduce the incidence of neural tube defects...
This paper proposes design of a weight measurement system capable of measuring weight in the range of micrograms to milligrams. The configuration of the system resembles with a conventional straw balance. Unlike straw balance the proposed system employs a force overcome technique. It does not employ any spring as that in case of other types of electromagnetic balance and any vibrating element present...
This paper presents an accurate surface formulation based on the contour integral method and the Dirichlet-to-Neumann operator to calculate the impedance and admittance parameters of transmission lines of arbitrary shape. The formulation only requires a discretization of the boundaries of the conductors and dielectrics, as opposed to the entire cross-section, which results in fast computations.
Cloud computing is a new hype in computer industry, which has different thoughts by different researchers. But beyond those thoughts, cloud has some limitation also which needs to be more focused. Basically cloud is based on use par pay scenario identified by user's services. But for each and every rewarding, that services cloud needs some predefine requirement circumstances to follow which affect...
For neural probes to be used chronically for years in the human body, they must provoke minimal scarring. Recently, a number of groups have reported substantially reduced scar tissue using cellular scale electrodes below 15 μm in size. This size scale is accessible to manufacturing techniques, but can be very difficult to insert in the brain for most common electrode materials. In this study, we explore...
Accurate models for on-chip interconnects are required to study signal integrity issues in electronic systems. This paper presents a fast surface method to calculate the impedance of transmission lines with conductors of arbitrary shape, including those with irregular profile because of roughness. The presented technique is over 140 times faster than finite elements, which makes it an ideal tool to...
Although recent research has suggested model predictive control as a promising solution for minimizing energy costs of commercial buildings, advanced control systems have not been widely deployed in practice. Large-scale implementations, including industrial complexes and university campuses, may contain thousands of air handler regions each with tens of zones. A single centralized control system...
In this paper, we discuss the possibility of numerically solving electromagnetic radiation problems from microstrip structures with only contour discretization of the radiating elements. We demonstrate that such a numerical method can be realized by exploiting the underlying physics of microstrip surfaces, and combining the so-called contour integral method with the equivalence principle. Such a numerical...
