Research ArticleOpen accessIn the abstractReview of Photochemical Smog Pollution in Jakarta Metropolitan, IndonesiaDollaris R. Suhadi, M. Awang, M. N. Hassan et al.An analysis of photochemical smog pollution in Jakarta was attempted using data from the existing air quality monitoring stations. Ground-level ozone potential is high in Jakarta due to the high traffic emissions of ozone precursors and the favorable surface meteorological conditions. Despite the frequent missing data during the 1996-1999 monitoring, which resulted in lower ozone values, ozone episodes were significantly … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,247 accessesView PDF Cite

Research ArticleOpen accessIn the abstractQoS Based IPTV over LTE-WLAN Heterogeneous NetworksMohamed Matoui, Noureddine Moumkine, Abdellah AdibHeterogeneous networks required IP Multimedia Subsystem (IMS) technologies to perform their control signaling and improve their communication services. However, the highest IPTV-QoS cannot be performed using IMS only as it cannot differentiate between IPTV video components. In this paper, we implement our IPTV-flow label technique in LTE-WLAN heterogeneous systems that used to improve QoS by providing IPTV sub traffic priority … …Journal of Computer Science, Vol. 15, Issue 4 · 19 Apr 2019 · 7,628 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordCollision Avoidance Modelling in Airline Traffic Based on the Change of Airplane Movements and Dynamic CloudsYudhi Purwananto, Chastine Fatichah, Waskitho Wibisono et al.An Air Traffic Controller (ATC) system aims to manage airline traffic to prevent collision of the airplane, called the Collision Avoidance (CA). The study on CA, called Conflict Detection and Resolution (CDR), becomes more critical as the airline traffic has grown each year significantly. Previous studies used optimization algorithms for CDR and did not involve the presence of cumulonimbus clouds. … …Journal of Computer Science, Vol. 17, Issue 1 · 20 Jan 2021 · 7,237 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSECURITY IN VEHICULAR AD HOC NETWORK BASED ON INTRUSION DETECTION SYSTEMOmkar Pattnaik, Binod Kumar PattanayakImplementation of mobile ad hoc networks has eventually captured practically most of the parts of day-to-day life. One variation of such networks represents the Vehicular Ad Hoc Networks (VANETs), widely implemented in order to control day-to-day road traffic. The major concern of VANETs is oriented around providing security to moving vehicles that makes it possible to reduce accidents and traffic … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 27 Dec 2013 · 7,022 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAnalysis of the Model Checkers' Input Languages for Modeling Traffic Light SystemsPathiah Abdul Samat, Abdullah Mohd Zin, Zarina ShukurProblem statement: Model checking is an automated verification technique that can be used for verifying properties of a system. A number of model checking systems have been developed over the last few years. However, there is no guideline that is available for selecting the most suitable model checker to be used to model a particular system. Approach: In this study, … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,887 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordOptimal Control of the D-Policy M/G/1 Queueing System with Server BreakdownsKuo-Hsiung Wang, Ching-Chang Kuo, Jau-Chuan KeThis study deals with a single server in the D-policy M/G/1 queueing system in which the server is turned off at the end of each complete period and is activated again only when the cumulative completion times of the customers in the system exceeds a given level D. While the server is working, he is subject to breakdowns according to … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,604 accessesView PDF Cite
