Both factors contribute heavily towards a user's satisfaction which is essential in an ‘experience economy’. Proceeding with identified literature related to ‘usability’ and ‘user experience’, this research attempts to identify whether there is a significant impact on five different factors related to usability and user experience and benchmark them to suit user's overall satisfaction. The methodology for the research followed the identification of the theory involved in terms of five factors with Web application use in terms of user's satisfaction. A structured questionnaire based on the five factors was next drawn up and used on a sample of 88 Web application users. The collected data was analysed using a statistical tool. The results were further validated using a primary data collection with 20 Web application users. A structured interview process was used for the purpose. The use of a common factor ‘satisfaction’, helped reveal that usability and user satisfaction only were affected as against the other three variables. Perhaps, a more detailed study may reveal the absorption of the other variables as related to user satisfaction.","PeriodicalId":343372,"journal":{"name":"2017 6th National Conference on Technology and Management (NCTM)","volume":"45 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":"126878823","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}

Malabe is the entrance to the Colombo across New Kandy road, Battaramulla, Rajagiriya, Borella, Kollupitiya towards Colombo. It is noticed that the pedestrian interruption with the vehicle flow from each direction of Malabe intersection generate a considerable delay to the vehicle users. This interruption generates traffic queues and even cause blocking of the vehicle at the intersection. The efficiency and the performance of the intersection have become very low, especially in the peak hours. The objective of this study is to quantify the delay of vehicle users through an economic evaluation. The delay will be evaluated in terms of additional vehicle operational cost and the additional travel time. Speed variation of vehicles due to the interruption with pedestrians have been analyzed over the 3 road segments intersect at the Malabe Junction. Kaduwela road, Athurugiriya road and Battaramulla road are specifically observed for the total number of vehicles and pedestrians crossing alone the pedestrian crossings. Simultaneously, the speed variation of the vehicles is analyzed to check the additional travel time and to quantify additional vehicle operational cost due to delay. New Zealand Guidelines for transportation were used in this study as the indices have not been developed for the developing countries like Sri Lanka.","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":"131217318","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}

Therefore, it is crucial to have an accurate timely estimation of VKT. Both traffic and non-traffic measurement methods are popular among the transport planners and researchers. Very few studies have conducted in Sri Lanka for estimating the VKT. This study proposes to estimate the VKT based on the number of household daily trips, which are collected through the interviews. The interviewer records the mode of travel, total number of kilometer travelled, and number of passengers. The socio-demographic information is also collected and this includes age, gender, employment status, income and residential area. The estimation of total VKT are derived from survey respondents' total number of kilometers each travelled during the previous 12 months in Southern Province, Sri Lanka. The collected data are also used to estimate the personal kilometer travelled and characteristics of travelers in Southern Province.","PeriodicalId":343372,"journal":{"name":"2017 6th National Conference on Technology and Management (NCTM)","volume":"52 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":"126811680","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 to extract the full potential of CUDA one should, at the least be familiar with the programming model and should have a fair understanding of the memory and the cache architecture. Yet most of the domain experts from domains that warrant high performance computing are ill trained to develop efficient CUDA programs that would extract the necessary performance. In this paper we argue that this gap can be bridged by exposing the CUDA architecture as an API for manipulating matrices. We observe that many of the high demanding scientific computations can be expressed as matrix manipulations, where the need for high performance stems for the size of the matrix. We present a Software as a Service (SaaS) solution to bridge this gap where a domain specialist uploads the data as matrices and specify the operations as an equation involving the uploaded matrices via web GUI. Then the back end will process the request using CUDA and return the results via the GUI. The CUDA code for handling matrix operations are highly optimized and the domain specialist can simply use them without knowing the underlying intricate details.","PeriodicalId":343372,"journal":{"name":"2017 6th National Conference on Technology and Management (NCTM)","volume":"6 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":"115074822","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}

Voice interaction is natural and require no additional technical knowledge. But while using voice commands humans frequently use uncertain information. In the case of object manipulation on a table, frequently used uncertain terms “Left”, “Right”, “Middle”, “Front”…etc. These terms fail to depict an exact location on the table and the interpretation is governed by the robots point of view. Depending solely on vocal cues is not ideal as it requires the users to explain the exact location with more words and phrases making the interaction process cumbersome and less human like. However, using hand gestures to pinpoint the location is as natural as using the voice commands and frequently used when manipulating items on a surface. When compared to voice commands use of hand gestures is a more direct and less cumbersome approach. But when used alone hand gestures can result in errors while extracting the pointed location making the user dissatisfied. This paper proposes a multi-modal interaction method which uses hand gestures combined with voice commands to interpret uncertain information when placing an object on a table. Two fuzzy inference systems have been used to interpret the uncertain terms related to the two axes of the table. The proposed system has been implemented on an assistive robot platform. Experiments have been conducted to analyze the behaviour of the system.","PeriodicalId":343372,"journal":{"name":"2017 6th National Conference on Technology and Management (NCTM)","volume":"17 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":"133050211","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}

Still quality control of ceramic tile industry is done mostly by manually. Manual inspection is labor intensive, costly and less in efficiency. Further, the accuracy of the defect detection is lower due to harsh industrial environment and human errors. To overcome such drawbacks this project proposes an automated inspection system for ceramic tile industry based on image processing techniques. This system can detect color variations and defects such as corner damages, edge damages and middle cracks on the surface of the tile with high accuracy and efficiency. The tiles are compared with a good quality reference tile using image processing concepts using Matlab software. Based on this comparison the tile quality is classified. The system was checked with 110 real ceramic tiles consisting of defected tiles with cracks, corner damages and color variations. The results were outstanding with of 96.36% detection accuracy rate. The processing time for one tile was approximately 2 seconds. This outstanding achievement of results reflects that this automated system can effectively replace manual ceramic tile detection system with better accuracy and efficiency.","PeriodicalId":343372,"journal":{"name":"2017 6th National Conference on Technology and Management (NCTM)","volume":"106 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":"124768992","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}
