Actuator Fault Estimation for Multi-agent Systems: A Sliding-mode Observer-based Approach
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
This study is concerned with the design of a distributed fault estimation scheme for linear multi-agent systems subject to actuator faults. For each agent, a sliding-mode observer-based estimator module is proposed that ...
An overview of the plastic waste and recycling status in Qatar
(2019 , Conference Paper)
It has been estimated that the average Municipal Solid Waste (MSW) generation rate per capita in the Gulf Co-operation countries (GCC) is approx. 1.5 kg/person/d, with Qatar reaching almost 1.4 kg/person/d, as it was ...
Pull-off characterization of FRCM/Concrete interface
(
Elsevier Ltd
, 2019 , Article)
Fabric-reinforced cementitious matrix (FRCM) composites are usually surface-applied for strengthening reinforced concrete (RC) structures. The efficacy of the FRCM strengthening systems is dependent on the FRCM/concrete ...
Biomechanical design of a composite femoral prosthesis to investigate the effects of stiffness, coating length, and interference press fit
(
Elsevier Ltd
, 2018 , Article)
Traditionally, high stiffness hip prostheses are associated with aseptic loosening. Hence, the effects of stiffness, coating length, and interference press fit on load sharing and micro-movements are investigated for a ...
Tunable properties based on regioselectivity of 1,2,3-triazole units in axially chiral 2,2?-linked 1,1?-binaphthyl-based copolymers for ions and acid responsiveness
(
Elsevier Ltd
, 2018 , Article)
The synthesis and optical studies of a new chiral binaphthyl-based polymeric sensor are described herein. The polymers were prepared using the copper-catalyzed azide?alkyne cycloaddition reaction between fluorene and ...
Fracture Analysis of a Special Cracked Lap Shear (CLS) Specimen with Utilization of Virtual Crack Closure Technique (VCCT) by Finite Element Methods
(
Springer New York LLC
, 2017 , Article)
Some of the most important characteristics due to a fracture investigation of a special specimen are taken into account. Debonding considerations for a composite/steel cracked lap shear (CLS) specimen by utilization of ...
Detecting emotions in English and Arabic tweets
(
MDPI AG
, 2019 , Article)
Assigning sentiment labels to documents is, at first sight, a standardmulti-label classification task. Many approaches have been used for this task, but the current state-of-the-art solutions use deep neural networks (DNNs). ...
Single-Voxel H MR spectroscopy of cerebral nicotinamide adenine dinucleotide (NAD ) in humans at 7T using a 32-channel volume coil.
(
Wiley
, 2019 , Article)
Reliable monitoring of tissue nicotinamide adenine dinucleotide (NAD ) concentration may provide insights on its roles in normal and pathological aging. In the present study, we report a H MRS pulse sequence for the in ...
Seismic Assessment of Existing Lowrise and Midrise Reinforced Concrete Buildings Using the 2014 Qatar Construction Specification
(
American Society of Civil Engineers(ASCE)
, 2018 , Article)
Qatar is considered to have predominantly low seismic activity despite being close to some of the most active seismic zones in the world, including the Zagros thrust belt. However, the strong earthquakes that have recently ...
Sensor fault detection and isolation of an industrial gas turbine using partial kernel PCA
(
9th IFAC Symposium on Fault Detection, Supervision and Safety for Technical Processes, SAFEPROCESS 2015
, 2015 , Conference Paper)
In this paper, partial kernel principal component analysis (PKPCA) is studied for sensor fault detection and isolation of an aeroderivative industrial gas turbine. Principal component analysis (PCA) is an effective tool ...
