The drivers normally keep their vehicle engine on while waiting for their turn to cross the intersection at signals, and a result of this extra fuel is consumed. This small amount of fuel wastage becomes a huge quantity when aggregated over number of cycles per day and number of signalized intersections. This study was carried out in Colombo, commercial capitals of Sri Lanka. For estimating the excess fuel consumed by vehicles during idling at signalized intersections, two signalized intersections with medium traffic volumes were considered. The selected signalized intersections were Borella and Narahenpita. The primary data for this research study, traffic volume and idling delay were obtained through field surveys. Required vehicle idling fuel consumption data were obtained from previous research. It was observed that the presence of heavy traffic congestion at the signalized intersections was the main reason for huge amount of fuel wastage from the vehicles. After the implementation of remedial measures, which are suggesting in this study, fuel loss during idling of vehicles at the signalized intersections can be reduced.","PeriodicalId":343372,"journal":{"name":"2017 6th National Conference on Technology and Management (NCTM)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125518604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a solution for this problem the Corporate Owned Personally Enabled (COPE) concept or idea introduced. In this concept, company owned devices can be used for both corporate and personal use of the employees. But in COPE stopping leakage of corporate data to outside as well as securing the privacy of the user is challenging. The Enterprise Secure Center (ESC) platform discussed here will consider about separation of corporate data from personal data to secure both organization information and personal information from being compromised. The ESC have an application mechanism which will enable COPE environment to secure organization data while allowing employees to use corporate devices for their personal use. ESC platform also provides answers to user's privacy issues and will be an initial step to implement BYOD within an organization as COPE is a part.","PeriodicalId":343372,"journal":{"name":"2017 6th National Conference on Technology and Management (NCTM)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115564143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, it has enhanced the consumer satisfaction as well as spread of experiences. However, even with the collaboration of social influence there are some visible short comings potentially appearing in such systems. In fact, the contribution of social influence is still in an evolving state. The reliability of products is such recognized key issue that still appears in exiting social E-commerce systems. In this context we introduce a social influence model combined with a built in social network which further improves the customer reliability and satisfaction on available products. Thus, it can propagate reliable knowledge among community and optimize product recommendation process. The implemented model considers the personal preferences of respective consumers, their social influences in social network and external social influences to the system for the execution. Furthermore, it operates as a multi-agent system. The model has been validated by two sample data sets of consumers and products. As the results, majority have picked products suggested by combining external influences, internal social influences, and personal preferences. Therefore it has concluded that recommendation of products considering above three combinations is more effective.","PeriodicalId":343372,"journal":{"name":"2017 6th National Conference on Technology and Management (NCTM)","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122755650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ad-hoc networks establish connections between nodes without the help of centralized nodes but with the help of its neighbour nodes. The nodes are movable and can change its position frequently, so it maintains a dynamic interconnection between nodes in the network and adapts to dynamic topologies. MANETs are characterized by dynamic mobile nodes, with limited battery sourced power. These mobile nodes also act as routers taking its roles such as finding new routes, acting as an intermediate node, deciding best routes and keep a connection with mobile nodes. Any mobile node in the network can make the connection directly to any node within its transmission range, but due to its limited power, its transmission range also limited. Reactive routing protocols are effective than proactive routing protocols on MANETs since it can reduce extra overheads. However, reactive routing protocol suffers from excessive flooding in route discovery process. Authors focus on an existing solution called Expanding Ring Search (ERS) which decreases the flooding by manipulating Time to live (TTL) in AODV. ERS is also is inefficient in some scenarios. When the source is far from the destination ERS is worse than flooding [4]. Authors proposing a modification in ERS to avoid this problem which will make ERS efficient when the MANET consists a node (common node) that frequently accessed by most of the nodes.","PeriodicalId":343372,"journal":{"name":"2017 6th National Conference on Technology and Management (NCTM)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115234566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Run-Off-Road (ROR) crashes could be identified as the most critical among highway related crashes. Previous research studies on Traffic Engineering has found that the road side elements will have a positive influence toward ROR crashes. Hence, the study explores the relationship of roadside elements with drivers' speed selection and lateral position. In this research study, the effect of road side vegetation and utility poles on drivers' speed selection and lateral positioning was evaluated. A straight roadway section and horizontal curve roadway section with varying road side vegetation were selected to get the required data for the study. Fifty vehicle were observed at each location to get the speeds and lateral positions. Collected data was analyzed using Multiple Regression Analysis technique to generate models to find drivers' speed selection and lateral positioning of vehicle on road. Study found that in lightly vegetated roadways, subjects drove speedier and drove much near the edge of the road. At the point when the scene changes into more vegetated, subjects drove much slower and drove near to the center of the road. The models demonstrate that the impact of road side vegetation way much higher in curved roads areas than straight segments. Therefore, it is recommended to post a speed limit sign and proper monitoring system at each critical curved roadway section in the country.","PeriodicalId":343372,"journal":{"name":"2017 6th National Conference on Technology and Management (NCTM)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114877962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As such, a canal might have the same prismatic cross section and an even bed profile along its course. Such characteristics do not support rich biota, something a sustainable society expects. Several past studies have attributed heterogeneity to be an important factor for a healthy stream. In this study the deflectors were used to introduce the heterogeneity in canals. In tandem studying flow complexity by deflectors, their role with respect to sediment (sand) and seed transport, and fisheries were also studied. The model canal's (laboratory flume) homogenous velocity of 0.4 m/s changed to a range of values from 0.1 to 0.7 m/s after placing deflectors. Similarly, water depth changed from a uniform 30 mm to a range from 20 mm to 70 mm. This resulted in formation of flow patches similar to flow patches formed by meso-scale physical habitats such as pools and riffles. Sediment deposition was patchy and seemed to be stable as only a minor bedload movement was observed for prolonged durations. This meant it is possible to achieve a quasi-equilibrium state in field canals where upstream brings sediments. Seed trapping was weak for floating type seeds, whereas non-floating seeds managed to get deposited with sediment. Fishes quickly migrated to the pool like areas that resulted from deflectors. The results suggested the role of deflectors in transforming a homogenous channel to heterogeneous channel that has the potential to have rich biota which is essential in ecological rehabilitation works.","PeriodicalId":343372,"journal":{"name":"2017 6th National Conference on Technology and Management (NCTM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129560427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
