Indian hydro power plants operating in geographically young Himalayan range have to handle silt laden flow particularly during monsoon periods. Equipment like hydro turbines causing severe damage and show declined performance after few years of operation. They get severely damaged under erosive wear. One of the major consequences of this erosive wear is gradual loss in efficiency. This paper presents...
This research paper analyzes the electrical behavior of single gate (SG) and dual gate (DG) organic thin film transistors (OTFTs). To better understand the device physics and conduction mechanism, an analytical model for drain current is derived incorporating the empirical parameters. The effect of two gate insulator capacitances along with depletion capacitance of the organic semiconductor active...
In this paper, the size of the battery energy storage system (BESS) of a grid-connected PV system is determined so that the system will be sufficient to supply the load as well as the total annual operating cost (AOC) remains as minimum as possible. Here the feed-in-tariff plan is adopted, where power can be bought from the grid as well as can be sold back to the grid if surplus power is available...
Glow Swarm Optimization(GSO) and Particle Swarm Optimization(PSO) algorithms are proposed in this paper for optimal tuning of PI controllers for Load Frequency ControUer(LFC) design. To visualize the effectiveness of the proposed method, a two area interconnected power system is considered as a test system. To prove the robustness of the proposed controller and to stabilize the frequency of oscillations,...
In modern years we see some growth in technology and for better traffic control on road with these some technologies the moving vehicle can do the better communication in Ad-hoc network which developed a new kind of technology like Vehicular Ad-hoc Network(VANET). VANET provides wireless communication with vehicle to road side unit. VANET can perform the communication between V2V, V2I, I2I. VANET...
The aim of the Project management System is to develop a web portal to automate the work of the three entities in the system — the Project Coordinator, Project Guide and Project Group. A Web portal is designed to make the entry of various activities easier for the users. The project coordinator's task is to lead, direct and communicate with the other entities. The activities will be carried forward...
This paper covers the issues related to the use of mobile phone for commission of cyber-crimes. Definition of mobile crime and its various types are shown. The laws prevailing in India for the crimes related to cyber world are given. The statistics of India's cyber-crime over the last few years is explained with graphs and charts. The state wise distribution of cyber-crimes in India is shown. The...
The state-of-the-art downsampling method for graph signals has been constructed by using maximum spanning trees (MSTs) of the graphs. For the graph signals defined on unweighted densely connected graphs, such as social network data, the sampling rates via MST-based downsampling are not close to 1 over 2, leading to a unbalanced downsampling phenomenon on multi-level downsampling. The unbalance hinders...
Texture+depth (RGBD) images provide information about the geometry of a scene, which could help improve current image matching performance, e.g., in presence of large viewpoint changes. While depth has been mainly used for processing keypoint descriptors, in this paper we focus on the keypoint detection problem. In order to produce a computationally efficient viewpoint-covariant multiscale representation,...
Tensor decomposition is an important tool for many applications in diverse disciplines such as signal processing, chemo-metrics, numerical linear algebra and data mining. In this work, we focus on PARAFAC and Tucker decompositions of three-way tensors with non-negativity and/or sparseness constraints. By using an all-at-once optimization approach, we propose two decomposition algorithms which are...
We present an iterative algorithm to extract the voice source waveform from recordings of speech for speaker identification. The method detects glottal closings, then constructs a speaker-dependent library of glottal pulse waveforms by clustering data windows centered on the linear prediction error time-series at the glottal closures. With the voice source modeled as scaled and shifted glottal pulses,...
This paper considers a network in which a source-destination pair needs to establish a confidential connection against an external eavesdropper, aided by the interference generated by another source-destination pair that exchanges public messages. Our goal is to identify the secrecy rate performance benefits that can be brought by exploiting co-channel interference. We consider two scenarios: 1) the...
In this paper, it is shown that the Power Spectral Density (PSD) of late reverberant speech can be described by a first-order Infinite Impulse Response (IIR) model with the pole related to the reverberation time. Utilizing this first-order IIR model, an online method for reverberation time estimation (RTE) from a recorded reverberant signal is proposed. The proposed method takes advantage of processing...
On behalf of the organization committee, it is our great pleasure to welcome you to the University of Edinburgh and Heriot-Watt University, in Edinburgh UK, for the 17th IEEE International Workshop on Signal Processing Advances in Wireless Communications, SPAWC 2016. We are looking forward to hosting the world leading experts in signal processing for communications and networking who will share the...
We present an EM algorithm for Maximum Likelihood estimation of the location, scale, and skew, and shape parameters of the z distribution, also known as the generalized logistic function (type IV). We use the Barndorff-Nielsen, Kent, and Sørensen representation of the z distribution as a Gaussian location-scale mixture to derive an EM algorithm for estimating the location, scale, skew, and shape parameters...
Clutter, which is occurred by noise which has more intensive reflection than the buried objects such as noise of the transmitter and receiver antennas and the ground surface reflection interference, makes the identification of targets in Ground Penetrating Radar (GPR). Aim of this paper is to achieve a novel, more effective and faster clutter reduction method by using Lifting Wavelet Transform (LWT)...
In this study, same amplitute sounds of sinuzoidal, square and saw tooth wave in frequencies of 100 Hz, 1 kHz and 10 kHz have been generated during 1 second. These sounds have been listened 5 times by a subject. The averaged power spectrums of the EEG which gathered from the subject have been represented in the frequencies of 0–4 Hz, 4–7 Hz ve 8–12 Hz and evaluated.
Now a days verification has become one of the most important challenges in getting advanced SOC devices in the market. With the advancement of technology, there is a need to integrate more components in SoC that results in increased chip complexity. This complexity issue in SoC must be resolved by some advanced methodology. Industry experts consider that in the overall design effort, the verification...
