Modelling the dynamic pile-soil-pile interaction in a multi-layered half-space
( DC/ConfOrg , 2015 , Conference Paper)Within the context of railway ground-borne vibration, the dynamic pile-soil-pile interaction remains an area that has not been sufficiently investigated. Whilst a number of researchers have scrutinised the vibration response ... -
Modelling the Severity of Plastic Shrinkage in Cementitious Materials
( Qatar Univesrity Press , 2020 , Conference Paper)"Plastic shrinkage cracking in cement-based materials occurs between the mixing and the final setting of the mixture, where rapid evaporation of the mixed water is the main cause behind the phenomenon. The induced cracks ... -
Modelling the symmetric and asymmetric relationships between oil prices and those of corn, barley, and rapeseed oil
( Elsevier Ltd , 2019 , Article)This study, using linear and nonlinear Autoregressive Distributed Lag (ARDL) Models, investigates the dynamic linkages between oil prices and agricultural commodities. The results from the linear model show that barley, ... -

Modelling trends in road crash frequency in Qatar State
( Inderscience Enterprises Ltd. , 2019 , Article)The data-based regression models are widely popular in modelling the relationship between the crash frequencies and contributing factors. However, one common problem usually associated with the classical regression models ... -
Modelling wave behaviour of elastic helical waveguides
( Springer Nature , 2020 , Conference Paper)Curved and straight waveguides are ubiquitous in engineering structures. For modelling these structures in the mid-frequency and high-frequency range, the knowledge of the wave behaviour can be greatly beneficial. This ... -
Modelling, analysis and performance improvement of an SRU's access request queue in multi-channel V2I communications
( Elsevier B.V. , 2015 , Conference Paper)This paper presents a concise yet comprehensive description of a multi-channel Vehicle-to-Infrastructure (V2I) communication system. Existing mathematical models for such a system overlook some of its essential behavioural ... -
Modelling, analysis, and implementation of a switched-inductor based DC/DC converter with reduced switch current stress
( John Wiley and Sons Inc , 2021 , Article)This paper proposes a technique for switch current stress reduction in a Switched Inductor DC-DC Boost Converter (SIBC). The proposed technique comes up with a low-cost design, high voltage conversion ratio with a less ... -
The Models of a General Component of a Distributed Computing Systems Based On Stochastic Petri Nets
( Qatar University , 1994 , Article)In this paper we propose models of a distributed computing system (DCS) based on general stochastic Petri nets (GSPN). We also propose the means to decrease the number of states. We indicate that the complexity of DCS ... -
Models of Speech Processing
( Taylor & Francis , 2015 , Book chapter)One of the fundamental questions about language is how listeners map the acoustic signal onto syllables, words, and sentences, resulting in understanding of speech. For normal listeners, this mapping is so effortless ... -
