Cluster validity index based on n-sphere
( IEEE , 2014 , Conference Paper)In this paper, we propose a new cluster validity index (CVI) based on geometrical shape. Classic CVIs are based on a combination of separation and compactness measures and may include a measure of overlap between clusters. ... -
Cluster-based Cooperative Multicast for Multimedia Data Dissemination in Vehicular Networks
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)With the development of communication technologies, vehicular network applications have evolved from basic traffic safety and efficiency applications to information and entertainment applications. The implementation of ... -
Clustered binary consensus in sensor motes
( VDE VERLAG GMBH , 2014 , Conference Paper)In this work, we extend and adapt the binary consensus algorithm to operate using clusters in a wireless sensor network. Binary consensus is a decision making algorithm used to cause distributed entities to agree on the ... -
Clustering of lifestyle risk factors among Algerian adolescents : Comparison between urban and rural area
( Qatar University Press , 2021 , Poster)Background: Lifestyle behavior risk factors (LBRs) such as sedentary behavior, physical inactivity, smoking, unhealthy eating patterns and being overweight/obese play a major role in the development or prevention of NCDs. ... -
Clustering of Lifestyle Risk Factors among Algerian Adolescents : Comparison between Urban and Rural Areas: GSHS Data.
( MDPI , 2021 , Article)Compare the clustering of LBRs between urban and rural Algerian adolescents. Data of this cross-sectional study was derived from the Global School-based Health Survey (GSHS). A self-administered, anonymous questionnaire ... -
CMOS compatible silicon slot ring resonator sensor
( SPIE , 2019 , Conference Paper)We propose a fully CMOS compatible optical sensor based on the ring resonator mechanism. The waveguide structure of the sensor utilizes the silicon on insulator slot waveguide configuration. The analyte fills the slot and ... -
CMV reduction in a three-to-seven phase direct matrix converter using SVPWM
( Institution of Engineering and Technology , 2019 , Article)The pulse-width modulation (PWM)-controlled modern electric drives causes some serious problems such as the generation of common-mode voltage (CMV) and high dv/dt. The CMV might cause high-frequency leakage currents that ... -
CNN feature and classifier fusion on novel transformed image dataset for dysgraphia diagnosis in children
( Elsevier , 2023 , Article)Dysgraphia is a neurological disorder that hinders the acquisition process of normal writing skills in children, resulting in poor writing abilities. Poor or underdeveloped writing skills in children can negatively impact ... -
CNN Features vs Classical Features for Largescale Cultural Image Retrieval
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)Modern applications for cultural content enrichment and management require low delay image retrieval methods in large databases. Classical image retrieval methods are suitable for certain applications but are also known ... -
