Research ArticleOpen accessAll words, across the recordMeasurement of Ground Level Ozone at Different LocationsYasmen A. Mustafa, Sinan J. MohammedProblem statement: Ground level ozone is the most important index substance of photochemical smog. Photochemical smog is now observed in many urban and industrial centers around the world and it has become a common phenomenon in many large cities. Ozone is a most harmful pollutant for humans, in addition it plays an important role in damaging vegetation and materials. Therefore … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 13 Jun 2012 · 7,408 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordVariation of Surface Ozone Recorded at the Eastern Coastal Region of the Malaysian PeninsulaAida Shafawati Ismail, Mohd Talib Latif, Siti Zawiyah Azmi et al.Problem statement: Variations of ozone (O3) concentrations in the Eastern Coastal Region of the Malaysia peninsula were investigated using data obtained from the Malaysian Department of the Environment. The aim of this study was to determine the monthly and seasonal variations of ozone concentrations at all monitoring sites. This study deals with the air quality data recorded at four air … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,075 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCluster Based Time Division Multiple Access Scheduling Scheme for Zigbee Wireless Sensor NetworksB. Meenakshi, P. AnandhakumarIn IEEE 802.15.4 ZigBee Wireless Sensor Networks, an efficient scheduling mechanism is required for reliable data transmission. Further, concurrent transmission of huge data through CSMA/CA incurs more packet collision rate. This complicated condition has to be eliminated to improve the system throughput. In this study, we propose to deploy cluster based TDMA scheduling mechanism for IEEE 802.15.4 ZigBee Wireless Sensor … …Journal of Computer Science, Vol. 8, Issue 12 · 26 Nov 2012 · 6,685 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBayesian Changepoint Analysis of the Extreme Rainfall EventsWan Zawiah Wan Zin, Abdul Aziz Jemain, Kamarulzaman IbrahimProblem statement: This study assesses recent changes in extremes of annual rainfall in Peninsular Malaysia based on daily rainfall data for 50 rain-gauged stations over the period 1975-2004. Approach: Eight indices that represent the extreme events are defined and analyzed, which are extreme Dry Spell (XDS), extreme Rain-Sum (XRS), extreme wet-day intensities at 95% and 99% percentiles (I95 and I99), … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 6 Feb 2012 · 7,255 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTime Clustering of the Occurrence of Sleep ApneaNur Zakiah Mohd SaatProblem statement: In this study, the inequality of apnea rates during sleep was investigated. Approach: This study used a database comprising 13 patients with apnea problems. The data was extracted from the MIT-BIH database. The Lorenz curve and Gini index were used to determine the inequality of apnea rates. In order to test for cluster, random or regular patterns of … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 23 Sep 2011 · 6,860 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHeart Rate Variability Analysis in Different Age and Pathological ConditionsM.E.S. Chelladurai, N. KumaravelProblem statement: Heart Rate Variability (HRV) has been used as a measure of mortality primarily with patients who had undergone cardiac surgery. The analysis of Heart Rate Variability (HRV) demands specific capabilities which are not provided either by parametric or nonparametric conventional estimation methods. The Empirical Mode Decomposition (EMD) adaptively estimates the Intrinsic Mode Functions (IMFs) of nonlinear nonstationary signals. … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 6,822 accessesView PDFCite
