Hence, to facilitate vision impaired individual in indoor environment requires a formal modelling approach for map generation and decision making about navigation pathways avoiding obstacles. The proposed data model consists \"AccessBIM\" database (DB) and API functions. The \"AccessBIM\" features such as, database connection initiation, function call, function return and database connection termination are organized as a series of function objects that meet the various needs of the database to maintain the relational schema. The proposed API primarily consists of two components, namely; DB connector and the API functions. Proposed \"AccessBIM\" DB will be implemented using real-time database such as \"PostgreSQL\". The weighted focus will be given to the areas such as Queries, Indexes and Transactions in relation to tuning the DB and the queries. The performance of the proposed API will be evaluated based on the time required to parse and Data insert rate and retrieval rates.","PeriodicalId":142561,"journal":{"name":"2015 Fifteenth International Conference on Advances in ICT for Emerging Regions (ICTer)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132370035","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}

In this paper, we propose two distinct approaches to find optimal traffic light cycles using Multi-agent Systems (MAS) and Swarm Intelligence (SI) concepts and compare the efficiency of these solutions against a default strategy under heterogeneous traffic regions using same input parameters. The solutions obtained are simulated using SUMO (Simulation of Urban MObility), a well-known microscopic traffic simulator. We have investigated both approaches with two large and heterogeneous metropolitan areas with hundreds of traffic lights located in the cities of Colombo in Sri Lanka and Chennai in India, and our research solutions are shown to obtain optimal traffic light cycles in both scenarios. In comparison with predefined static cycle programs (using SUMO's default traffic light cycle generation algorithm), our solutions achieved quantitative improvements for the two main objectives: reducing the waiting time and the journey time of vehicles significantly and qualitatively improving smooth traffic flow over the regions.","PeriodicalId":142561,"journal":{"name":"2015 Fifteenth International Conference on Advances in ICT for Emerging Regions (ICTer)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115846422","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}

In higher educational system, the students are supposed to gain an in-depth knowledge of subject matter in a course. Online and face-to-face education have different techniques that could be combined together in a blended environment for educating the undergraduates. The intention of this study is to identify effective ways to develop the Student-Centred Learning for students who are following courses in a blended environment. A final year course of undergraduate students was selected as a case study to carry out the investigation. The selected course was designed considering both continuous learning activities for formative assessment and individual and group work for summative assessment. According to the analysis of different data gathered together with students' feedback, we evaluate the applicability of student-centred learning in a blended environment. This paper also justifies the importance of ICT enabled environment in teaching and learning to implement the student-centred learning.","PeriodicalId":142561,"journal":{"name":"2015 Fifteenth International Conference on Advances in ICT for Emerging Regions (ICTer)","volume":"195 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121065908","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}

Because posts on Twitter are publicly viewable by default, Twitter can be used to get up-to-date information on events like natural disasters, disease outbreaks or sports events. Building a cohesive summary out of tweets on long running events is an interesting problem which research community is interested in. But the abundance of tweets containing user opinions and their sentiments towards a topic necessitates the need of extracting newsworthy tweets from a large stream of tweets on a single topic. But most of such methods require large hand-labeled corpora to be used for training the model. But this is not practical for a rapidly updating medium like Twitter. In this paper we address this problem with the introduction of a novel heuristic based annotation scheme to generate training dataset for the system. A hand-labeled corpus of tweets is only used for benchmarking the objectivity classifier. Our classifier could achieve an F1-score of 80% on a manually annotated gold standard dataset.","PeriodicalId":142561,"journal":{"name":"2015 Fifteenth International Conference on Advances in ICT for Emerging Regions (ICTer)","volume":"278 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127714165","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}

However, robust and lightweight protocols are yet to be implemented for multihop communication. The latest IEEE 802.11 standard released in 2012 captures the concept of multihop MANETs under Wireless Mesh Networks and proposes Hybrid Wireless Mesh Protocol (HWMP) as the default multihop path selection protocol. Previous studies on the performance of HWMP have not addressed operating scenarios of mass mobility (to model human user mobility), non-availability of root nodes (to model absence of infrastructure support) and a wide span of node densities (to model different application scenarios). This paper analyses the scalability of HWMP in a MANET of IEEE 802.11 standard wireless mesh stations that move at human walking speeds. The end-to-end delay, data packet delivery ratio and path selection control overhead are evaluated in the presence of random waypoint and mass mobility models for increasing node densities. The simulation results show that there are no significant variations in any of the above important performance metrics among static, random waypoint mobility and mass mobility models. Furthermore, HWMP shows almost a linear path selection control overhead profile for increasing node densities while the packet delivery ratio and the end-to-end delay reaches a steady level as node density increases up to about 250 nodes.","PeriodicalId":142561,"journal":{"name":"2015 Fifteenth International Conference on Advances in ICT for Emerging Regions (ICTer)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127868288","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}
