In software projects, there is a data repository which contains the bug reports. These bugs are required to carefully analyse and resolve the problem. Handling these bugs humanly is extremely time consuming process, and it can result the deleying in addressing some important bugs resolutions. To overcome this problem, researchers have introduced many techniques. One of the commonly used algorithm...
Both tracking and robust performance are important issues in control engineering. Tracking performance represents how precise the actuator can follow the reference, while robust performance shows how far the actuator can function properly when plant uncertainty and disturbance appear. This works assess both tracking and robust performance of two popular control algorithms i.e Sliding Mode Control...
With the large-scale photovoltaic power plants and centralized network, more and more new energy grid problem arises. Distributed photovoltaic power plants connected to the grid, and can lead to accidents such as power grid voltage instability occurs at a certain probability. The fundamental reason is the unreliability of distributed photovoltaic power generation. Solar irradiance and ambient temperature...
Quality assurance (QA) is a crucial process to ensure the maximize accuracy of the data delivered to client. Equipped with many moving parts whose relative positions can change over time depending on use, handling frequency and care, the QA is essential for TLS. Furthermore, with rapid and dense three-dimensional (3D) data collection ability, TLS has gain interest for many accurate 3D applications...
Emotional decoding ability has been repetitively shown to be impaired in alcoholic patients. The present study aims to extend previous findings on emotions deficits examining the auditory stimuli recognition ability in alcoholism. Twenty-six alcohol-dependent patients, abstinent from alcohol for at least four weeks, were compared to 26 controls matched for sex, age and socioeconomic level. Subjects...
Text classification is an important step in many data analysis procedures. The demand on text classification algorithm is booming due to the increase of the amount of digital data, especially in the healthcare field. A customizable and accurate algorithm is expected to produce positive impact on the efficiency of many data analysis procedures. In this work, we proposed a novel algorithm for accurately...
A multiplier has a significant impact on the speed and power dissipation of an arithmetic processor. Precise results are not always required in many algorithms, such as those for classification and recognition in data processing. Moreover, many errors do not make an obvious difference in applications such as image processing due to the perceptual limitations of human beings. Error-tolerant algorithms...
The capacitor voltage transformer (CVT) is a potential transformer (PT) composed of capacitive voltage divider and electromagnetic unit. In high voltage classes, the capacitor voltage transformer has the advantage of simpler structure and lower cost in comparison with electromagnetic potential transformer (PT), so potential transformers with voltage class of 220kV and above are CVT basically. Transformer...
Single-ISA heterogeneous multicore processors have gained increasing popularity with the introduction of recent technologies such as ARM big.LITTLE. These processors offer increased energy efficiency through combining low power in-order cores with high performance out-of-order cores. Efficiently exploiting this attractive feature requires careful management so as to meet the demands of targeted applications...
The electrical performance of capacitive voltage transformers (CVT) and thus the accuracy of the device is not only dependent on the transformation ratio of the intermediate inductive transformer but also on the capacitive divider, the compensating coil and the damping devices. All components of the CVT are prone to ageing when they are in operation over a long lifetime, especially under harsh environmental...
A Doppler velocity log measures relative velocity between an instrument and the bottom of a body of water by transmitting acoustic pulses that are scattered off the bottom. The scattered sound is received and the Doppler shift is measured. Like any other sensor, the data quality of a Doppler velocity log can be quantified by a variance and a bias. The goal of this work is to model error sources that...
With the advantage of high dielectric strength and low cost, capacitive voltage transformers (CVTs) have been applied to measure the voltage in power grid widely. Recently, CVTs own the problem of big error, insulation performance degradation and high failure rate due to the complicated environment. Secondary load is an important factor to impact CVT's accuracy by analysis. Consequently, we established...
This paper introduces a general implementation procedure for the measurement of harmonic phase angles using Power Quality (PQ) instruments. It is intended to fill this gap of the standards IEC 61000-4-7 and IEC 61000-4-30, particular with focus on grid measurements. While measurement for a single time instant is well defined, the paper focuses on methods to aggregate the harmonic phase angles in frequency...
Analysis of a medical dataset having missing values and then filling the missing values through different approaches exists in the literature. However, the classification accuracies achieved using these approaches have not been so promising when analyzed. It is this reason; which implicitly motivated us to study and address new methods for imputation. In this paper, we propose an approach for efficient...
The data are generated very rapidly from different information sources. These generation of data is increasing day by day from various sources such as automated data collection tools, database systems, e-commerce and social media websites. There is an explosive growth of data from terabytes to petabytes. It is essential to extract valuable knowledge from these large data. Since large amount of data...
An energy efficient hearing aid current mode readout amplifier using accuracy compensation and adaptive bias current techniques is presented, for the improved accuracy with the saved power. Compared with the conventional current mode amplifiers, the amplifier with the techniques is characterized by the pole-zero canceling feedback loop and the adaptive current mode feedback loop. With the techniques,...
In this paper, the most authentic and efficacious method for cardiac arrhythmia classification using Multiclass Support Vector Machine (MSVM) is presented. The authors have considered classification of 6 beat types such as normal sinus rhythm (N), Premature Ventricular Contraction (PVC), Right Bundle Branch Block (RBBB), Left Bundle Branch Block (LBBB), Tachycardia (TA) and Bradycardia (BR) by implementing...
High Intensity Focused Ultrasound as a non-invasive treatment method has gaining its popularity in various clinical application. HIFU is usually used with navigation system with which to make pre-operative plan. Our group developed a US-guided HIFU system for breast cancer treatment. In order to precisely remove the tumor region and reduce the damage to the surrounding normal tissue to minimal level,...
International instrument transformer standardization efforts include alternative designs in their scope. Rogowski coils fall within the so-called “low power passive current transformers” category. The main disadvantage of easy-to-use split-core Rogowski coils can be overcome by adding a simple ferrite core at the clasp: short-circuiting the magnetic path by a soft magnetic part in the region where...
Lung Cancer is a disease of infection in lung due to uncontrolled cell growth which affects its functionality. It is mostly incurable due to that early detection of Lung Cancer is important. Early detection and treatment may help for patient's survival. Normally, diagnosis of lung cancer includes chest X-ray, ECG, Citi scan, MRI etc. In cancer diagnosis Artificial Neural Network and Fuzzy Min-Max...
