Obstacles and features of health information systems: A systematic literature review
( Elsevier , 2021 , Article Review)Background: Currently many healthcare systems are supported by an increasing set of Health Information Sys-tems (HISs), which assist the activities for multiple stakeholders. The literature on HISs is, however, fragmented ... -
Occupant behavior in Indian apartments
( Springer, Singapore , 2018 , Book chapter)© Springer Nature Singapore Pte Ltd. 2018. Occupant adaptation happens to be the key mechanism behind achieving thermal comfort in buildings. User's thermal adaptation is under researched in India, although it is important ... -
Occupant's thermal comfort in Qatari offices - Need for the new adaptive standard
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Qatar's per capita energy consumption is one of the highest in the world, consuming 30.184 TWh as of 2012. Buildings contribute significantly (80%) to this, with air-conditioning taking a lion's share. Qatar does not have ... -
OCR based feature extraction and template matching algorithms for Qatari number plate
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)There are several algorithms and methods that could be applied to perform the character recognition stage of an automatic number plate recognition system; however, the constraints of having a high recognition rate and ... -
OCR-based hardware implementation for qatari number plate on the Zynq SoC
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)Automatic Number Plate Recognition (ANPR) systems have become widely used for safety, security, and commercial purposes. A typical ANPR system is based on three essential stages: Number Plate Localization (NPL), Character ... -
OFDM Full-Duplex DF Relaying under I/Q Imbalance and Loopback Self-Interference
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)We analyze the outage probability of dual-hop full-duplex (FD) decode-and-forward (DF) relaying for an orthogonal frequency-division multiplexing (OFDM) system in the presence of in-phase and quadrature-phase (I/Q) imbalance ... -
