This paper develops a model for Wells turbine using Xilinx system generator (XSG)toolbox of Matlab. The Wells turbine is very popular in oscillating water column (OWC) wave energy converters. Mostly, the turbine behavior is emulated in a controlled DC or AC motor coupled with a generator. Therefore, it is required to model the OWC and Wells turbine in real time software like XSG. It generates the...
The concept of Submarine launched Underwater Acoustic to Above water Radio Communication Gateway Buoys for strategic communication with submarines without periscope depth excursions was identified as one of the thrust area that we should focus. Hence the research in this area was intensified and a PoC Demonstration was carried out at [1]. This paper covers a detailed record experiments carried out...
This paper presents the analytical potential modeling of Double Gate (DG) Tunnel Field Effect Transistor (TFET) at 50 nm channel length. In this model approach the channel potential is sum of a long channel potential and a short channel perturbation along with the whole structure rather than just the Si/SiO2 interface or the channel centre. For the validation of our analytical modeling approach we...
A new optimal proportional integral derivative (PID) controller is designed in this work in order to achieve dynamic stability for a Hydro Turbine Generating (HTG) unit under various operating conditions. The proposed controller minimizes a Quadratic Performance Measuring Index (QPMI) in order to find the optimal Proportional Integral Derivative (PID) parameters via a Linear Quadratic Regulator (LQR)...
Maxwell first described the theoretical basis for the propagation of electromagnetic waves in 1873[1]. For the next 140 years we have seen tremendous developments in the area of Wireless Communications. Today, virtually everything in the world is connected by wireless technologies, whether it's on the surface of earth or in the deep space. Surprisingly, an important frontier is left out, which occupies...
The changes in dc characteristics of AlGaN/GaN HEMT after ICP-CVD silicon nitride (SiNx) passivation using two different recipes were investigated. Room temperature Raman analysis was performed to determine the stress state of the AlGaN layer after SiNx passivation. The changes in the stress state of the device after passivation was correlated with the shift in threshold voltage and changes in drain...
Remote health monitoring system with Clinical Decision Support System as a key component could potentially quicken the response of medical specialists to critical health emergencies experienced by their patients. A monitoring system, specifically designed for cardiac care with ECG signal analysis as the core diagnostic technique, could play a vital role in early detection of a wide range of cardiac...
Internet of things (IoT) is connected world of capabilities and services that enable interaction among physical objects supported by technologies such as sensors, RFID, wireless, mobile, cloud and internet. In this paper we analyze the drivers for IT services to use IoT and challenges involved and establish the need for accelerators. Various service applications can be built using IoT in all the verticals...
Several localization techniques have been proposed to identify the exact location of sensor nodes. Localization is important for computation of many applications such as routing in wireless sensor network. Energy preservation is a challenge in wireless sensor network and many algorithms have already been proposed. The localized node lifetime is maximized by using energy-efficient routing, use of minimum...
Demand Response (DR) and Time-of-Use (TOU) pricing refer to programs offering incentives to customers who reduce their energy use during times of peak demand. A demand response system coordinates the demand and supply between the energy provider and the customer. In this study, a turn-key solution is developed to offer demand response services for residential customers. A cognitive residential ANFIS-based...
The two most important objectives of the data center operators are to reduce operating cost and minimize carbon emission. Consolidation of data centers is not always possible and big enterprise end up having data centers in multiple locations across different cities and countries. In such a diverse deployment manual monitoring is not a cost effective solution. ASHRAE [1] suggested considering the...
Problems encountered due to size reduction of transistor in fabrication of integrated circuits leads us to switch to a new paradigm, which uses these fundamental effects as working principles. Quantum-Dots are used as basic building blocks for this new paradigm. In this paper we discuss the implementation of a Look Up Table (LUT) using this Quantum-Dot Cellular Automata (QCA). The software used to...
