The problems engendered by the conflicting imperatives of development and ecology show no sign of ending, and every day more locations are added to the list of landscapes poisoned by human activity. This vital book, featuring an international set of authors, is a key reference for researchers and environmental managers, as well as anyone involved in the mining industry or landscape remediation. The...
This paper presents the instability problem of a broadcast control framework for multi-agent systems in executing certain motion coordination tasks. First, response of unstable solution using a standard broadcast control framework is demonstrated by choosing one motion coordination task as an example of the unstable case. In order to solve the problem, the standard broadcast control framework has...
Ability of wavelet transform in accessing time and frequency information at the same time make it widely used in analyzing bio-signals like electromyography (EMG). Discrete wavelet transforms (DWT) and stationary wavelet transform (SWT) are examples of analysis based on wavelet. Both analyses are based on decomposition technique and splitting signals into few frequency band. The different is DWT will...
To obtain a high-quality surface electromyography (EMG) recording, the signal must be acquired as far as possible from the muscle innervation and tendon zone. This study presents a technique to indicate better electrode positions for surface EMG of the upper limb muscles during wrist extension and flexion. Ten volunteers participated in this research. Surface EMG signals were collected from flexor...
The Compact Muon Solenoid (CMS) detector installed at the CERN Large Hadron Collider (LHC) has an extensive muon system which provides information simultaneously for identification, track reconstruction and triggering of muons. As a consequence of the extreme particle rate and high integrated charge, the essentiality to upgrade the LHC has given rise to the High Luminosity phase of the LHC (HL-LHC)...
The Compact Muon Solenoid (CMS) detector is one of the two general-purpose detectors at the CERN LHC. LHC will provide exceptional high instantaneous and integrated luminosity after second long shutdown. The forward region |η| ≥ 1:5 of CMS detector will face extremely high particle rates in tens of kHz/cm2 and hence it will affect the momentum resolution, efficiency and longevity of the muon detectors...
Dissolved Gas Analysis (DGA) is one of the common approaches that can be used to detect incipient faults in transformers. According to IEEE C57/104-2008 and IEC 60599 standards, there are many DGA techniques that can be used to interpret the type of faults. In this paper, an alternative method to diagnose faults in transformers based on Rough Set (RS) and Fuzzy Logic (FL) is proposed. The rules for...
Determining the level of pulse repetition interval (PRI) agility is important in the field of Electronic Intelligence (ELINT) in order to provide warning receiver and jammers with the appropriate information in order to take action. This paper uses smoothed instantaneous power in order to estimate the PRIs of an incoming radar emitter signal. The test signals considered for this work is made up of...
Time-frequency analysis is an evolution of mathematical ideas and concepts used in the analysis of time-varying spectra of signals in order to cater for various problems in different fields. One of such fields of interest is radar related problems. This paper reviews the recent advancements made in this area with the aid of time-frequency (t-f) tools within the last year till date, it presents a good...
Electromyography (EMG) is one of the indirect tools in indexing fatigue. Fatigue can be detected when there are changes on amplitude and frequency. However, various outcomes from literature make researchers conclude that EMG is not a reliable tool to measure fatigue. This paper investigates EMG behavior of biceps femoris in median frequency and mean absolute value during five days of Bruce Protocol...
This paper presents variations of Ultra Low Frequency (ULF) and Very Low Frequency (VLF) during moderate geomagnetic storm using ground based observatories, Magnetic Data Acquisition System (MAGDAS)/Circum-Pan Magnetic Network (CPMN) magnetometer and Atmospheric Weather Electromagnetic System for Observation Modeling and Education (AWESOME) VLF receiver. In this analysis, the recorded ULF horizontal...
Commonly abbreviated Local Area Network LAN is a computer network that covers only a small area networks, such as campus computer networks, buildings, offices, in homes, schools or smaller. Currently, most LANs based on the IEEE 802.3 Ethernet technology using devices such as hubs and switches devices, which have a data transfer speed of 10, 100, or 1000 Mega bit per second (Mbps). In this paper,...
In today's world Built-In Test is the necessity for the designs of digital logic circuits. However, providing solutions with such concept requires cumbersome and typical procedures of designs and because of this majority of the design go without incorporating the features of Built-In Test in the designs. The design procedures further aggravates if optimal design is needed. Hence, in view of this,...
This paper proposes a new idea and implementation tool for two level minimization of Boolean expressions. A simpler and more versatile method is developed by exploiting the adjacency field relationships between Gray code and decimal numbers. Our algorithmic procedures also consider the optimal use of don't care terms. We implemented our algorithm in MATLAB and tested accuracy and efficiency for large...
Current market environment, ever growing difference between depleting energy resources and increasing power demand and increased expectations of customers from utility companies has made it necessary to adopt some good operational policies by electric utility companies. So the focus of utility companies has shifted towards increased customer focus, enhanced performance and to provide reliable supply...
The effect of superthermal electrons obeying kappa/Cairn's distribution on low frequency electrostatic global modes is studied. The plasma is considered inhomogeneous and the effect of arbitrary size density gradients alongwith non-Maxwellian effects is discussed analytically on the growth or damping of the drift/cyclotron frequencies. The general solution of the bounded non-Maxwellian plasma and...
EMG based control becomes the core of the pros-theses, orthoses and rehabilitation devices in the recent research. Though the difficulties of using EMG as a control signal due to the complexity nature of this signal, the researchers employed the pattern recognition technique to overcome this problem. The EMG pattern recognition mainly consists of four stages; signal detection and preprocessing feature...
The main aim of this paper is an improvement of the famous Scale Invariant Feature Transform (SIFT) algorithm used in place categorization.
