Space Elevators: Orbital Ring System
(2019-05)The main purpose of a space elevator is to carry payloads into space as an alternative to conventional rockets. The following poster showcases the feasible version of the Space Elevator: The Orbital Ring System. -
Space size relative to prey width and total cover in an area both influence the habitat choices of freshwater angelfish Pterophyllum scalare in mesocosms
(2012)Prey survivorship can vary with average space size/prey width (Sp/Py) and total cover within an area (Ct/At). Hypotheses predict that prey survivorship is maximized at intermediate Sp/Py values and that prey survivorship ... -
Spatio-Temporal Feature-Extraction Techniques for Isolated Gesture Recognition in Arabic Sign Language
(IEEE, 2007)This paper presents various spatio-temporal feature-extraction techniques with applications to online and offline recognitions of isolated Arabic Sign Language gestures. The temporal features of a video-based gesture are ... -
Spatiotemporal Mapping and Monitoring of Mangrove Forests Changes From 1990 to 2019 in the Northern Emirates, UAE Using Random Forest, Kernel Logistic Regression and Naive Bayes Tree Models
(Frontiers, 2020)Mangrove forests are acting as a green lung for the coastal cities of the United Arab Emirates, providing a habitat for wildlife, storing blue carbon in sediment and protecting shoreline. Thus, the first step toward ... -

Spectrum Occupancy Measurements and Cognitive Radio System Implementation
(2017-01)Nowadays, radio spectrum is mostly crowded and occupied by many fixed wireless services. Therefore, there is less opportunity of finding a vacant band (spatially or temporally) for deploying new wireless communication ... -
Spectrum Sensing Algorithms for Cooperative Cognitive Radio Networks
(2010-05)In the past few years, there have been remarkable developments in wireless communication technology, leading to a rapid growth in wireless applications. However, this dramatic increase in wireless applications is severely ... -
Spectrum Sensing Via Reconfigurable Antennas: Fundamental Limits and Potential Gains
(Springer, 2016-07)We propose a novel spectrum sensing technique in cognitive radio networks that provides diversity and capacity benefits using a single antenna at the Secondary User (SU) receiver. The proposed scheme is based on a ... -
Spelling Errors of Arab Students: Types, Causes and Teachers' Responses
(2011-06)It has been noted that many learners of English, including Arab learners in UAE public schools exhibit difficulties with English spelling. These difficulties have been attributed to a number of causes, such as the irregularity ... -
Spent Caustic Treatment Using Advanced Oxidation Processes
(2012-05)Mixed refinery spent caustic is an industrial wastewater that is generated from oil refineries. Spent caustic undergo two treatment steps, chemical oxidation followed by biological post treatment step. The goal of chemical ... -
Spreading of oil on water in the surface-tension regime
(Springer, 2014-12)The third stage of oil spreading on water, in which surface-tension force promotes spreading against the resisting viscous effect, is investigated using a similarity solution in combination with an integral boundary-layer ... -
Stability and bifurcation analysis of a discrete-time predator-prey model with strong Allee effect
(Taylor & Francis, 2020-03-16)In this paper, we investigate the impact of Allee effect on the stability of a discrete-time predator-prey model with a non-monotonic functional response. The proposed model supports the coexistence of two steady states, ... -
Stability and removal of dexamethasone sodium phosphate from wastewater using modified clays.
(2014-08)Stability and removal of dexamethasone sodium phosphate (DSP) from wastewater produced at Al-Quds University Campus were investigated. Kinetic studies in both pure water and wastewater coming from secondary treatment ... -
Stability and Removal of Naproxen and Its Metabolite by Advanced Membrane Wastewater Treatment Plant and Micelle-Clay Complex
(2014-05)Naproxen, a non-steroidal anti-inflammatory drug, commonly used for fever, inflammation and for different health problems, as found for many pharmaceuticals has been recently detected in sewage effluents, surface, and ... -
Stabilization of Pluronic P-105 Micelles with an Interpenetrating Network of N,N-Diethylacrylamide
(American Chemical Society, 2000)N,N-Diethylacrylamide (NNDEA) was polymerized in the presence of Pluronic P-105 micelles. The polymerizations resulted in an interpenetrating network of poly(NNDEA) and P-105 that stabilized the micelles at concentrations ...
