Adaptive optimized DTC-SVM using metaheuristic Bat algorithm for DSIM fed by IMC based on robust synergetic speed controller
( John Wiley and Sons Ltd , 2021 , Article)Direct torque control (DTC) suffers from the large ripples of the torque and flux, which leads to deteriorating the system performances. Replacing the conventional back-to-back converter with an indirect matrix converter ... -
Adaptive Prediction Models for Data Center Resources Utilization Estimation
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Article)Accurate estimation of data center resource utilization is a challenging task due to multi-tenant co-hosted applications having dynamic and time-varying workloads. Accurate estimation of future resources utilization helps ... -
Adaptive Sampling
( John Wiley & Sons, Ltd , 2015 , Book chapter)Animal populations are often highly grouped. For example, fish can form large, widely scattered schools with few fish in between. Even rare species of animals may form small groups that are hard to find. Applying standard ... -
Adaptive Single-Phase Auto-Reclosing Approach for Shunt Compensated Transmission Lines
( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)Single-phase auto-reclosing (AR) scheme is widely employed in extra high voltage (EHV) transmission networks to quench transient faults without completely removing the faulted transmission line (TL). Long EHV TLs are ... -
Adaptive sliding mode control for a general nonlinear multicompartment lung model with input pressure and rate saturation constraints
( John Wiley and Sons Ltd , 2016 , Article)Summary In this article, we develop an output feedback adaptive sliding mode controller for a general multicompartment lung mechanics model with nonlinear resistance and compliance respiratory parameters. Specifically, for ... -
Adaptive Sliding Mode Fault Diagnosis for LPV Systems with Uncertain Scheduling Variables
( IEEE Computer Society , 2018 , Conference Paper)This paper presents an adaptive sliding mode observer for actuator fault diagnosis of linear parameter-varying (LPV) systems with imperfectly measured scheduling variables due to noisy or faulty measurements. The developed ... -
Adaptive sliding mode observer for sensor fault diagnosis of an industrial gas turbine
( Elsevier Ltd , 2015 , Article)Sensors are one of the crucial components in gas turbines and the failure in sensor measurements can lead to serious problems in maintaining their safety and performance requirements. Our aim in this paper is to develop ... -
Adaptive sliding mode-based diagnosis of actuator faults for LPV systems
( John Wiley and Sons Ltd , 2017 , Article)In this paper, an adaptive sliding mode observer is developed for actuator fault diagnosis of linear parameter-varying systems. The main advantage of the proposed approach is its ability to cope with time-varying distribution ... -
An adaptive step-down procedure for fault variable identification
( Taylor & Francis , 2015 , Article)In a process with a large number of process variables (high-dimensional process), identifying which variables cause an out-of-control signal is a challenging issue for quality engineers. In this paper, we propose an adaptive ... -
Adaptive thermal comfort in the different buildings of Darjeeling Hills in eastern India – Effect of difference in elevation
( Elsevier Ltd , 2018 , Article)Thermal comfort standards are required to provide comfortable indoor condition which has a positive effect on the occupant. However, the Predicted Mean Vote – Percentage People Dissatisfied (PMV-PPD) model which is used ... -
Adaptive two-stage inverse sampling design to estimate density, abundance, and occupancy of rare and clustered populations
( Public Library of Science , 2021 , Article)Sampling rare and clustered populations is challenging because of the effort required to find rare units. Heuristically, a practitioner would prefer to discontinue sampling in areas where rare units of interest are apparently ... -
The Adaptive, Pain Sensitive, and Global Symptoms Clusters: Evidence from a Patient-Based Study
( SAGE , 2023 , Article)Objectives: The largest epidemiologic study conducted about painful temporomandibular disorders (pTMDs) to date identified 3 clusters of individuals with similar symptoms—adaptive, pain sensitive, and global symptoms—which ... -
Adding colchicine to tocilizumab in hospitalized patients with severe COVID-19 pneumonia: An open-label randomized controlled trial
( Lippincott Williams and Wilkins , 2022 , Article)Introduction: Colchicine acts upstream in the cytokines cascade by inhibiting the nod-like receptor protein 3 (NLRP3) inflammasome while interleukin 6 (IL-6) receptor antagonists, such as tocilizumab, block the end result ... -
ADding negative pRESSure to improve healING (the DRESSING trial): a RCT protocol.
( BMJ Publishing Group Limited , 2016 , Article)INTRODUCTION: Obese women are more likely to develop a surgical site infection (SSI) following caesarean section (CS) than non-obese women. Negative pressure wound therapy (NPWT) is increasingly being used to reduce SSI ... -
Additional records of vector mosquito diversity collected from Al Khor district of North-eastern Qatar
( Elsevier , 2015 , Article)ObjectiveTo survey mosquito diversity in the north-eastern area, which includes the most important gas industrial city in Qatar, and to investigate the potential mosquitoes for transmitting diseases. MethodsA study was ... -
Additions to the flora of Qatar
( Qatar University , 1997 , Article)Collections and earlier studies on the plants of Qatar are limited and of recent origin — since the seventies. The latest of these in 1983 (El Amin) listed 300 species belonging to 202 genera in 56 families. At present, a ... -
Additive Manufacturing of Smart Material and Complex Structures
( Qatar University Press , 2021 , Poster)Additive Manufacturing (AM), typically referred to as rapid prototyping or three-dimensional (3D) printing has rapidly emerged as a sustainable, highly efficient and intelligent tool. Moreover, recent developments in novel ... -
Additive manufacturing of Ti-alloy: Thermal analysis and assessment of properties
( SAGE Publications Inc. , 2020 , Article)In this study, 3D printing of Ti6Al4V alloy is realized and the characteristics of the printed layer are examined. The morphological structures and metallurgical changes in the printed layer are assessed. Temperature and ... -
Additive Manufacturing Technology for Spare Parts Application: A Systematic Review on Supply Chain Management
( MDPI , 2022 , Article Review)Additive manufacturing (AM) is gaining interest among researchers and practitioners in the field of manufacturing. One major potential area of AM application is the manufacturing of spare parts, which affects the availability ... -
