Order Statistics-Based Design of UWB Receivers
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)We propose a non-coherent ultra-wideband (UWB) receiver that leverages a single-sample-per-pulse threshold approach to detect the transmitted symbol and is capable of mitigating the impact of impulse noise. Unlike classical ... -
Ordered clustering: A way to simplify analysis of multichannel signals
( IEEE , 2010 , Conference Paper)We describe here new possibilities offered by a clustering method routinely used by many petroleum companies and which could be used in other applications where analysis of multichannel signals has a significant role ... -
Organic fouling in forward osmosis: A comprehensive review
( MDPI AG , 2020 , Article Review)Organic fouling in the forward osmosis process is complex and influenced by different parameters in the forward osmosis such as type of feed and draw solution, operating conditions, and type of membrane. In this article, ... -
Organically modified nanoclay filled thin-film nanocomposite membranes for reverse osmosis application
( MDPI AG , 2019 , Article)This study validates, for the first time, the effectiveness of two nanoclays, that is, cloisite (CS)-15A and montmorillonite (MNT) at the polyamide (PA) active layer in the reverse osmosis (RO) membrane. Cloisite-15A is ... -
Organizational behavior attributes and sustainable construction adoption: An econometric analysis using data from Qatar
( American Society of Civil Engineers (ASCE) , 2016 , Article)Despite the efforts of governments to promote sustainable construction practices, the decision to adopt sustainability practices largely falls upon the firms involved in construction projects. This paper presents an ... -
An original controller design for a grid connected PV system
( IEEE , 2012 , Conference Paper)PV energy generation has been one of the most active research areas in the past decades due to its inexhaustibility and environmental-friendly aspects. However, the great deal is to utilize the solar energy effectively ... -
Orochi: investigating requirements and expectations for multipurpose daily used supernumerary robotic limbs
