A semantic approach for document clustering
( Academy Publisher , 2009 , Article)Conventional document mining systems mainly use the presence or absence of keywords to mine texts. However, simple word counting and frequency distributions of term appearances do not capture the meaning behind the words, ... -
A semi-analytical beam model for the vibration of railway tracks
( Academic Press , 2017 , Article)The high frequency dynamic behaviour of railway tracks, in both vertical and lateral directions, strongly affects the generation of rolling noise as well as other phenomena such as rail corrugation. An improved semi-analytical ... -
A semiparametric nonlinear mixed model approach to phase I profile monitoring
( Taylor and Francis Inc. , 2019 , Article)When process data follow a particular curve in quality control, profile monitoring is suitable and appropriate for assessing process stability. Previous research in profile monitoring focusing on nonlinear parametric (P) ... -
A semiparametric profile monitoring via residuals
( John Wiley and Sons Ltd , 2019 , Article)Profile monitoring is a vast area of research underneath the statistical process monitoring (SPM). Several methods for univariate and multivariate process control are found in literature to monitor the profile data, including ... -
A Senior Project-Based Multiphase Motor Drive System Development
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)Adjustable-speed drives based on multiphase motors are of significant interest for safety-critical applications that necessitate wide fault-tolerant capabilities and high system reliability. Although multiphase machines ... -
A sensitivity analysis approach to identify key environmental performance factors
( Hindawi Publishing Corporation , 2014 , Article)Life cycle assessment (LCA) is widely used in design phase to reduce the product's environmental impacts through the whole product life cycle (PLC) during the last two decades. The traditional LCA is restricted to assessing ... -
A sensor fault detection and isolation strategy by using a Dendritic Cell Algorithm
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)In this paper, an online sensor fault detection and isolation (FDI) scheme is proposed based on an emerging Artificial Immune System (AIS) algorithm, namely Dendritic Cell Algorithm (DCA). Our proposed methodology is ... -
A sensorless Kalman filter-based active damping technique for grid-tied VSI with LCL filter
( Elsevier Ltd , 2017 , Article)Employing the LCL passive filter in inverter-based distributed generation to ensure high quality power delivery comes at the expense of poor performance due to the resonance phenomenon. Literature elucidated several active ... -
A sentiment treebank and morphologically enriched recursive deep models for effective sentiment analysis in Arabic
( Association for Computing Machinery , 2017 , Article)Accurate sentiment analysis models encode the sentiment of words and their combinations to predict the overall sentiment of a sentence. This task becomes challenging when applied to morphologically rich languages (MRL). ... -
A series flywheel architecture for power levelling and mitigation of DC voltage transients in multi-terminal HVDC grids
( Institution of Engineering and Technology , 2014 , Article)This study proposes a new architecture of flywheel energy storage system (FESS) which can be implemented at generating unit (GU) level (e.g. wind turbine) or scaled up for application in grid-side converter (GSC) stations ... -
A service computing manifesto: The next 10 years
( Association for Computing Machinery , 2017 , Article Review)Mapping out the challenges and strategies for the widespread adoption of service computing is an important task. Service computing is a key paradigm that offers cross-disciplinary computational abstractions, architectures, ... -
A Service-Oriented Approach for Sensing in the Internet of Things: Intelligent Transportation Systems and Privacy Use Cases
( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)This paper presents a Sensing-as-a-Service run-time Service Oriented Architecture (SOA), called 3SOA, for the development of Internet of Things (IoT) applications. 3SOA aims to allow interoperability among various IoT ... -
A set of geometrical features for writer identification
( Springer , 2012 , Conference Paper)Writer identification is an important field in the forensic document examination. We propose in this paper a set of geometrical features that makes it possible to characterize writers. They include directions, curvatures ... -
A Shallow U-Net Architecture for Reliably Predicting Blood Pressure (BP) from Photoplethysmogram (PPG) and Electrocardiogram (ECG) Signals
( MDPI , 2022 , Article)Cardiovascular diseases are the most common causes of death around the world. To detect and treat heart-related diseases, continuous blood pressure (BP) monitoring along with many other parameters are required. Several ... -
A shear design model for RC beams strengthened with fabric reinforced cementitious matrix
( Elsevier Ltd , 2019 , Article)The shear behavior of fabric reinforced cementitious matrix (FRCM) strengthened beams requires more research efforts to be fully understood. A detailed investigation into the shear capacity of FRCM shear-strengthened beams ... -
A short analysis on the morphological characterization of colloidal quantum dots for photovoltaic applications
( Bentham Science Publishers , 2020 , Article Review)Due to its various advantages, colloidal quantum dots (CQDs) carry a prodigious deal of interest in low-cost photovoltaics. The possibility of tailored band gaps via quantum confinement effect facilitates photovoltaic ... -
A short-term probabilistic photovoltaic power prediction method based on feature selection and improved LSTM neural network
( Elsevier Ltd , 2022 , Article)With the increase of solar photovoltaic(PV) penetration in power system, the impact of random fluctuation of PV power on the secure operation of power grid becomes more and more serious. An efficient PV forecasting approach ... -
A Side-by-Side Comparison of Shaft Excavation locally in Qatar
( Qatar University Press , 2023 , Conference Paper)The city of Doha has grown and expanded rapidly in the last 20 years, but this growth has strained the city's infrastructure, including its aging sewerage system and treatment facilities. The Public Works Authority (Ashghal) ... -
A signal combining technique based on channel shortening for cooperative sensor networks
( IEEE , 2010 , Conference Paper)The cooperative relaying process needs proper coordination among the communicating and the relaying nodes. This coordination and the required capabilities may not be available in some wireless systems, e.g. wireless sensor ... -
