As one approach to enhancing response performance of RTOS-based systems, Oosako proposed a method for implementing both kernel objects and RTOS functionalities as hardware utilizing high-level synthesis, where TOP-PERS/ASP3 was assumed as an RTOS. This paper extends this method to deal with systems based on FreeRTOS. In FreeRTOS, tasks can be generated either statically or dynamically, whose control data are managed in linked lists. We place restrictions that all the tasks are generated before scheduler starts so that we can keep the task control data in an array. Software timers are dealt with as tasks that have their own timers. We also present methods to implement dispatch disabling for mutual exclusion and a data queue for asynchronous data communication. We have implemented a hardware module from a reduced version of a demo program main_full.c and TimerDemo.c bundled with FreeRTOS, which took less than 300 ns and 700 ns for task control and data queue operations, respectively.","PeriodicalId":405859,"journal":{"name":"TENCON 2021 - 2021 IEEE Region 10 Conference (TENCON)","volume":"238 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123325238","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}

The data gathered by these smart devices helps bring a strong integration of human, collective, and artificial intelligence within the city operation. With the advent and proliferation of electric vehicles (EVs), the EV charge point is a relatively new addition to this plethora of smart devices. We believe that the EV charge point can acquire enhanced functionality if it can be seamlessly integrated with the rest of the smart city infrastructure. For example, charging services can be stopped if smart grid or smart fire alarms sense an electrical overload or fire hazard in the vicinity. However, the interaction of an EV charge point with the smart city infrastructure requires seamless information exchange across various verticals. This horizontal flow of information is enabled by making the charge point complaint with the oneM2M platform. To this end, we present the design and fabrication of an EV charge point based on the OCPP communication standard and complaint with the oneM2M platform. Further, we discuss various use cases showing an increased functional capability of the EV charger due to access to data from other IoT devices.","PeriodicalId":405859,"journal":{"name":"TENCON 2021 - 2021 IEEE Region 10 Conference (TENCON)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121938977","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}

The resilience of electricity infrastructure ground assets and power system equipment can be improved by strengthening the foundations or re-engineering the vulnerable impact spots of equipment. However, understanding the criticality and thereby assessing resilience of underground cables is challenging due to the underground dynamics and the infrastructure spanning across a large geographical area. The cables go through different terrains and depths and the effects of earthquakes vary on these cables depending upon the magnitude. To address this problem, this piece of research explores the potential use of geospatial information software's to map underground cables to study the performance of underground cables by evaluating the repair rates and developing fragility curves for underground cables damaged based on utility data during an earthquake event. Based on the observed case-study, a resilience-based criticality framework is proposed for underground cables. This helps provide actionable and accepted metrics, particularly for short term and long-term resilience of underground cables in a distribution network.","PeriodicalId":405859,"journal":{"name":"TENCON 2021 - 2021 IEEE Region 10 Conference (TENCON)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128721045","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, the water quality parameters, such as temperature, Dissolved Oxygen (DO) and pH plays a significant role in the success of aquaculture. The Dissolved oxygen concentration in the fish farms has a greater influence on the outcome of the aquaculture. DO can vary drastically depending upon many external factors, such as feeding, stocking density, diseases etc. Sudden depletion in DO can result in mass mortality of fishes if the preventive actions are not prompt. To this end, computer vision-based behaviour detection plays a significant role. The present study proposes to develop a novel computer vision-based approach to detect swimming at the surface pattern. An experiment is a setup to capture and develop the dataset of fish movement patterns. The proposed method uses detections alone to identify the swimming at the surface pattern. These detections are clustered and the mean of the clusters are compared against the threshold for classifying the pattern as Swimming at the surface pattern. The threshold is identified using the position histogram from the dataset. The proposed method is efficient, lightweight and reliable making it suitable for deployment in smart systems. The proposed method is also compared with pattern detection using a tracking algorithm. The results highlight the reliability of the proposed method to detect the patterns in aquaculture.","PeriodicalId":405859,"journal":{"name":"TENCON 2021 - 2021 IEEE Region 10 Conference (TENCON)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127890263","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}
