is assumed as a stochastic process, also known as white noise, in this case. However, sometimes ambient excitation may contain some dominant frequency components which could be easily confused with natural frequencies of the structure. The separation of the true modal parameters from erroneous ones should be done on the next step using various methods ( Jacobsen, N-J Separating Structural Modes and…
The Moving Particles Semi-implicit (MPS) method was introduced in the mid-1990s by Koshizuka et al. cite{Koshizuka-1995} to simulate incompressible flows with free surfaces. As a fully Lagrangian particle-based method, it has several advantages in modeling of free surface flows with large deformation, fragmentation and merging, solids with complex geometry, multiphase flows and multiphysics problems. In recent years, much effort has been done to solve the problems of huge processing time…
In this paper wavelet based decomposition and reduction of EMG signal. Electromyography (EMG) signal is a biological parameter that recording the electrical activity of the muscles. It is a diagnostic tool to assess the health of muscles and the nerve cells that control them. The different levels of daubechies wavelet family are used to analyze the EMG signal. The EMG feature extracted from different level decomposition and reconstruction of the EMG signal. We used a single channel electrode…
organization. The model represents risk as a hierarchical decomposition of contributing factors, whose interrelationships are represented by a fuzzy rule set. The decomposition of risk can help to identify those elements that contribute most significantly to the calculated risk and hence allows us to take the necessary mitigating action. 3.2 BASIS OF APPROACH The civil aviation safety threat assessment system is a knowledge based system. Such systems are a collection of data representing the…
heart rate and the interval between consecutive heart beats. Previously traditional methods had been used for calculating heart beat as using hand with time, and after the appearance of the new method and devices those depend on computer program the HRV analysis become easier and more accurate. Thus this is the primary purpose of use the many methods to analyze HRV using Matlab program. , HRV is computed by analyzing beat-to-beat interval time series derived from an electrocardiogram (ECG), an…
ROI based Secured and Robust medical image watermarking in Transform domain. ABSTRACT: In medical field, It’s common to transmit medical image and medical reports from one hospital to other hospital for diagnosis of the diseases. In that case the patient personal information and medical image plays a vital role while transferring over network. Because if a third party got those information and he intentionally cross change the information of multiple patients with wrong medical images,…
issues like lack of knowledgeable resources to adapt to the new and changing technology, fierce competition with many other firms trying to get into this niche domain, no assurance of sustainability in long term etc. Despite of these challenges, Wipro…
Watson 1.Introduction Watson is a Question Answering system developed by IBM to compete against human opponents in Jeopardy which is a well-known television quiz show with a twist. Contestants are asked to phrase the question of a given answer from a selected category. The game of Jeopardy is considered a hard game for computers given its unstructured nature of questions from a vast number of domains and types. 2.History Before the start of the Watson project the team at IBM worked on…
percent of the questions, in a maximum of 3 seconds with over 80 percent accuracy. In order to take on the Jeopardy experiment developing and integrating an array of the QA technologies such as question classification, parsing, question decomposition, entity and relation detection, automatic source acquisition and evaluation, knowledge representation and reasoning, and logical form generation. To win in Jeopardy you must have confidence in the accuracy of your answers. The questions and the data…
