Real traffic-data based evaluation of vehicular traffic environment and state- of-the-art with future issues in location-centric data dissemination for VANETs

引用

Digital Communications and Networks 2017年第3期3卷 195-210页

作者： Abdul Hafidz Abdul Hanan Mohd. Yazid idris Omprakash Kaiwartya Mukesh Prasad Rajiv Ratn Shah Faculty of Computing Universiti Teknologi Malaysia (UTM) 81310 Skudai Johor Malaysia Centre for Artificial Intelligence University of Technology Sydney Australia School of Computing National University of Singapore (NUS) 117417 Republic of Singapore

Extensive investigation has been performed in location-centric or geocast routing protocols for reliable and efficient dissemination of information in Vehicular Adhoc Networks （VANETs）. Various location-centric routing protocols have been suggested in literature for road safety ITS applications considering urban and highway traffic environment. This paper characterizes vehicular environments based on real traffic data and investigates the evolution of location-centric data dissemination. The current study is carded out with three main objectives：（i） to analyze the impact of dynamic traffic environment on the design of data dissemination techniques, （ii） to characterize location-centric data dissemination in terms of functional and qualitative behavior of protocols, properties, and strengths and weaknesses, and （iii） to find some future research directions in information dissemination based on location. Vehicular traffic environments have been classified into three categories based on physical characteristics such as speed, inter-vehicular distance, neighborhood stability, traffic volume, etc. Real traffic data is considered to analyze on-road traffic environments based on the measurement of physical parameters and weather conditions. Design issues are identified in incorporating physical parameters and weather conditions into data dissemination. Functional and qualitative characteristics of location-centric techniques are explored considering urban and highway environments. Comparative analysis of location-centric techniques is carded out for both urban and highway environments individually based on some unique and common characteristics of the environments. Finally, some future research directions are identified in the area based on the detailed investigation of traffic environments and location-centric data dissemination techniques.

Antimicrobial Activity of Some Commercial Toothpastes and Antibiotics on Two Oral Pathogenic Bacteria—An in-Vitro Study

引用

Journal of Biosciences and Medicines 2024年第3期12卷 168-181页

作者： Abubaker Elrotob idris Kabalci Department of Biomedical Engineering Engineering Faculty Karabuk University Karabuk Türkiye Department of Electric-Electronic Engineering Engineering and Natural Science Faculty U&scedilak University U&scedilak Türkiye Department of Electric-Electronic Engineering Engineering Faculty &Scedil&imathrnak University &Scedil&imathrnak Türkiye

Oral health problems such as periodontal diseases, dental caries, and endodontic infections have a significant negative impact on oral health and impose a substantial financial burden on the global population. The prevalence of these issues is increasing due to the buildup of bacterial plaque and the growing resistance of bacteria to antimicrobial treatments. The aims of this study to evaluate the anti-bacterial activity of four types of antibiotics (Amoxicillin, Augmentin, Azithromycin and Metronidazole) and four types of toothpastes (Sensodyne, ipana, denta and cariax Gingival Kin) on two oral pathogenic bacteria (Streptococcus mutans and Staphylococcus epidermidis). Bacterial samples of previously isolated Streptococcus mutans and Staphylococcusepidermidis were used as test organisms and the Kirby-Bauer disc diffusion method was employed to assess the antibacterial efficacy of various antibiotics and evaluate the impact of different toothpastes using a filter paper disc agar measurement technique. Each filter disc was saturated with toothpaste solution in a test tube for approximately 30 to 40 seconds, after which they were placed on Mueller-Hinton broth bacterial cultures in petri dishes. These Petri dishes were then incubated at 37°C for 24 hours, and the clear zone’s diameter (inhibition zone in mm) was subsequently measured and the results were recorded. The results demonstrated that Sensodyne toothpaste and Metronidazole antibiotic were ineffective against both types of bacteria, while Augmentin and Amoxicillin were effective by high diameter inhibition zones of growth against S. mutans and Azithromycine against S. epidermidis. Also Ipana, Denta, and Cariax Gingival Kin toothpastes exhibited a moderate effect against the two bacteria. This study suggests that certain antibiotics and toothpastes can effectively inhibit the growth of harmful oral bacteria, but not all of them are effective.

Effect of pattern coating thickness on characteristics of lost foam Al-Si-Cu alloy casting

Transactions of Nonferrous Metals Society of China 2012年第9期22卷 2092-2097页

作者： Majid KARIMIAN Ali OURDJINI Mohd HASBULLAH idris Hassan JAFARI Department of Mechanical Engineering Islamic Azad University of Komeyni Shahr Esfahan 119-84175 Iran Department of Materials Engineering Faculty of Mechanical Engineering Universiti Teknologi Malaysia 81310 UTM Skudai Johor Malaysia Department of Materials Engineering Faculty of Mechanical Engineering Shahid Rajaee Teacher Training University Tehran 16785-136 Iran

An experimental study on lost foam casting of an Al-Si-Cu alloy was conducted. The main objective was to study the effect of pattern coating thickness on casting imperfection and porosity percentage as well as eutectic silicon spacing of the alloy. The results showed that increasing slurry viscosity and flask dipping time influenced the casting integrity and microstructural characteristics. It was found that thinner pattern coating produced improved mould filling, refined microstructure and higher quality castings containing less porosity.
