The person who needs WSN will have a pictorial idea of the sensor network. The problem in the traditional method is that the person who needs the WSN should explain the pictorial view of the sensor network to a commercial vendor and buy it from them or they should design it from the scratch. What we proposed in our solution is to develop a platform so that the person who needs the WSN can directly draw the pictorial view on a canvas and then it can automatically generate all the required firmware for the microcontrollers and wiring diagrams. The user is then required only to follow a few instructions to complete the real world implementation of WSNs. This paper is about developing a visual platform to design WSNs. The WSN designing platform was built as a web application, so it can manage a large number of supported sensors and microcontrollers. This means that if one user adds the device driver for any sensor or a microcontroller the other users can directly use it from the WSN design platform without worrying about hardware programming. Further, if anyone needs a new sensor or microcontroller to be supported by this visual design platform, this design tool will have interfaces to directly add new sensors and microcontrollers. The proposed method is affordable for developing custom wireless sensor networks.","PeriodicalId":6603,"journal":{"name":"2018 Moratuwa Engineering Research Conference (MERCon)","volume":"84 1","pages":"384-389"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75805700","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}

This paper presents the traffic based analysis related to performance of B128 and B130 route in Galle, Sri Lanka using basic traffic engineering parameters such as travel time, average and maximum speed, average acceleration and deceleration. So the main objective of this paper is to identify traffic related parameters of above routes at Galle. The driving data was collected using on board measurement method by installing a prototype GPS tracking device in light-duty cars (AXIO, AQUA, FIT, Vitz). The cycle construction was done according to the segment based cycle construction method and roads were segmented considering the major intersections. Driving cycles were constructed for morning peak, noon peak, evening peak and off peak hours in B130 route and off peak hours in B128 route and the travel time, average speed, maximum speed, average acceleration and average deceleration were obtained. According to results, the maximum average speed of 27.53 km/h was obtained at off peak hours and travel time of 892s is taken to travel from Hapugala junction to Galle in noon peak hours. However the maximum speed was obtained at noon peak hours.","PeriodicalId":6603,"journal":{"name":"2018 Moratuwa Engineering Research Conference (MERCon)","volume":"157 1","pages":"108-113"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74770911","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, applicability of NMT for language pairs that have high morphological variations is still debatable. Lack of language resources, especially a sufficiently large parallel corpus causes additional issues, which leads to very poor translation performance, when NMT is applied to languages with high morphological variations. In this paper, we present three techniques to improve domain-specific NMT performance of the under-resourced language pair Sinhala and Tamil that have high morphological variations. Out of these three techniques, transliteration is a novel approach to improve domain-specific NMT performance for language pairs such as Sinhala and Tamil that share a common grammatical structure and have moderate lexical similarity. We built the first transliteration system for Sinhala to English and Tamil to English, which provided an accuracy of 99.6%, when tested with the parallel corpus we used for NMT training. The other technique we employed is Byte Pair Encoding (BPE), which is a technique that has been used to achieve open vocabulary translation with a fixed vocabulary of subword symbols. Our experiments show that while the translation based on independent BPE models and pure transliteration perform moderately, integrating transliteration to build a joint BPE model for the aforementioned language pair increases the translation quality by 1.68 BLEU score.","PeriodicalId":6603,"journal":{"name":"2018 Moratuwa Engineering Research Conference (MERCon)","volume":"35 1","pages":"390-395"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85683470","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}

Even though there are many conventional methods to evaluate the degree of corrosion, most of them are destructive. Though there are significant efforts made to estimate the degree of corrosion nondestructively, reliable methods are yet to be established especially, for hidden or inaccessible corrosion. Moreover, the available methods, whether destructive or nondestructive, focus only on the surface corrosion (except in the cases of intergranular corrosion [IGC] of stainless steel) completely ignoring the corrosion pits that form beyond the limits of surface corrosion. Hence, this study includes these corrosion pits in estimating the degree of corrosion. In this study, selected steel samples were subjected to accelerated corrosion conditions and then tested ultrasonically. Ultrasonic longitudinal wave velocity to shear wave velocity ratio and the attenuation coefficient were measured using Ultrasonic Flaw Detector. These measurements were done even after removing the corrosion products from the surface. SEM analysis and the conventional weight loss measurements were also carried out. The correlations obtained between the degree of corrosion and ultrasonic parameters are presented.","PeriodicalId":6603,"journal":{"name":"2018 Moratuwa Engineering Research Conference (MERCon)","volume":"1 1","pages":"312-317"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80750455","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}
