On the detection of Kernel-level rootkits using hardware performance counters
( Association for Computing Machinery, Inc , 2017 , Conference Paper)Recent work has investigated the use of hardware perfor- mance counters (HPCs) for the detection of malware run- ning on a system. These works gather traces of HPCs for a variety of applications (both malicious and ... -
On the development of flywheel storage systems for power system applications: A survey
( IEEE , 2012 , Conference Paper)Energy storage systems cannot be considered energy sources but having the ability of storing and discharging energy. They have a vital rule in the reliability and power quality of power systems. There are several energy ... -
On the diet of the Pharaoh Eagle Owl, Bubo ascalaphus (Savigny, 1809), in Qatar, with an overview of its feeding habits
( Taylor and Francis Ltd. , 2014 , Article)The diet of Bubo ascalaphus in Qatar was assessed based on pellets collected from the first known nesting site of the species in the country. The pellets contained a total of 68 prey items, representing 9 different species: ... -
On the distributed binary consensus algorithm in wireless sensor networks
( IEEE , 2013 , Conference Paper)We consider the binary consensus problem over the wireless sensor networks (WSN), where each node of the network initially observes one of two states and the aim of each node is to decide which one of the two states was ... -
On the effect of proportional fairness in energy transfer for wireless powered communication networks
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)Wireless powered communication network (WPCN) is an emerging area of research where energy is transferred from the access point to the mobile terminals in the downlink and information is transferred in the uplink. In the ... -
On the effectiveness of emission penalties in decentralized supply chains
( Elsevier B.V. , 2019 , Article)In recent years, the emission of harmful pollutants, such as greenhouse gases, due to industrial activities have received considerable interest from both business and scientific communities. As a result, an increasing ... -
On the effects of combined atmospheric fading and misalignment on the hybrid FSO/RF transmission
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)Free-space optical (FSO) communication is known for its various impairments such as atmospheric turbulence and misalignment fading. In this paper, we study the performance of an FSO link operating under combined path loss ... -
On the Effects of Temperature on the Performances of FSO Transmission under Qatar's Climate
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)Strong atmospheric turbulence can highly affect the free space optical (FSO) link. In fact, the strength of turbulence is depending on weather factors where the temperature is considered as the main parameter increasing ... -
On the encapsulation of Olsalazine by ?-cyclodextrin: A DFT-based computational and spectroscopic investigations
( Elsevier B.V. , 2019 , Article)In this work, the supramolecular host-guest interaction of the prodrug Olsalazine (OLZ) and β-Cyclodextrin (β-CD) was examined experimentally and computationally. Experimentally, employing the UV–Vis spectroscopic method ... -
On the Ergodic Secrecy Rate of Massive MIMO Transmission with Partial Legitimate User CSI
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)In this paper, we consider the downlink transmission over a single-cell massive multiple-input-multiple-output (MIMO) system in the presence of multiple single-antenna eavesdroppers (massive MIMOME). We concentrate on the ... -
On the Error Performance of Non-orthogonal Multiple Access Systems
( IEEE Computer Society , 2020 , Conference Paper)Unlike orthogonal multiple access schemes, non-orthogonal (NOMA) ones have arisen as an appealing solution to meet the requirements of the upcoming era of massive connectivity. In NOMA schemes, users are allowed to ... -
On the estimation of reliabilty function in a Weibull lifetime distribution
( Taylor & Francis , 2008 , Article)The estimation of the reliability function of the Weibull lifetime model is considered in the presence of uncertain prior information (not in the form of prior distribution) on the parameter of interest. This information ... -
On the evaluation of flue gases capturing capacity of porous organic materials
( Avestia Publishing , 2016 , Conference Paper)Integrated Gasification Combined Cycle (IGCC) has been emerged as an efficient alternative to post and oxy-combustion systems for power generation with controllable CO2 capture and separation. However, this system operates ... -
On the evaluation of tweet timeline generation task
( Springer Verlag , 2016 , Conference Paper)Tweet Timeline Generation (TTG) task aims to generate a timeline of relevant but novel tweets that summarizes the development of a given topic. A typical TTG system first retrieves tweets then detects novel tweets among ... -
