Hardware PCA for gas identification systems using high level synthesis on the Zynq SoC
( Institute of Electrical and Electronics Engineers Inc. , 2013 , Conference Paper)One of the significant stages in a gas identification system is dimensionality reduction to speed up the processing part. This is even more important when the system is implemented on a hardware platform where the resources ... -
Harm Perception and Attitudes towards E-cigarette Use Among Qatar University Students: A Cross-Sectional Study
( Qatar University Press , 2021 , Poster)Background: Electronic cigarette (e-cigarette) use is becoming popular worldwide especially among youth. Research reported that university students have poor knowledge and misconceptions about the health risks of e-cigarettes, ... -
Harmed Trait Self-Control: Why Do People with a Higher Dispositional Malicious Envy Experience Lower Subjective Wellbeing? A Cross-Sectional Study
( Springer Netherlands , 2019 , Article)The literature reveals that dispositional benign and malicious envy can influence subjective wellbeing. Nevertheless, no study has yet explored the mechanisms accounting for their relationships. Therefore, the present study ... -
