Animal fats, non-edible oils and waste cooking oils are the main lipid sources of bio diesel production. Biodiesel production involves the main process of tranesterification where the triglyceride lipid source reacts into Fatty Acid Methyl Esters and Glycerol. Large amount of waste cooking oil is generated per day globally and it is a considerable amount of disposal of available energy. According to the health regulations of waste cooking oil, it is not supposed to be reused in the food industry. In this research, the main objective was to optimize the process requirements and to fabricate a Small and Medium-sized Enterprises (SME) level plant for the production of biodiesel from waste cooking oil. The product can be used in place of petroleum diesel for the automotive and industrial level applications without any environmental effect and it ensures the same performances of the internal combustion engines with required modifications.","PeriodicalId":237290,"journal":{"name":"2016 IEEE International Conference on Information and Automation for Sustainability (ICIAfS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124481395","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}

Dead-time is essential to prevent short circuit of DC link in PWM inverters. This causes dead-time effect which results in output waveform distortions and undesired characteristics. This paper deals with a new dead-time compensation scheme where a different approach is used in inserting dead-time into PWM inverters such that it does not cause any effect due to the introduced dead-time. In this approach, dead-time is applied only for either one of the switches depending on the output current polarity, ensuring no DC link shortage. This technique ensures an accurate output voltage magnitude with no phase delays. Simulation and experimental results of the proposed method are presented to validate the effectiveness.","PeriodicalId":237290,"journal":{"name":"2016 IEEE International Conference on Information and Automation for Sustainability (ICIAfS)","volume":"346 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116549409","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 primary focus of the proposed INS is to provide a logical, computationally efficient algorithm which serves as a basis to map and navigate unknown environments. For demonstrative and testing purposes, the INS was implemented both in simulation form using MATLABTM™ SIMULINK™ as well as practically, using an omni-directional robot (ODR) platform. The INS requires input data acquired from a stereo vision system mounted on the ODR, and functions by employing a spatial information spectrum of its surrounding using the data acquired by the vision system. This proposed information spectrum is a novel tool that conveys the already identified objects and information gaps (pathways the robot can travel through, to obtain more information about the unknown environment) within the vicinity of the robot, to the INS. The INS then decides the most efficient way to map and traverse this unknown environment based on this information spectrum. Experiments were carried out in a multitude of simulated environments. Metrics such as time taken to completely map these environments and the information gathered within a given time, were used to demonstrate the efficacy of the proposed algorithm. A further extension to this algorithm is proposed to handle dynamic and moving obstacles in unknown environments.","PeriodicalId":237290,"journal":{"name":"2016 IEEE International Conference on Information and Automation for Sustainability (ICIAfS)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115993891","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}

Obfuscation has emerged as a promising approach to ensure supply chain security by countering the reverse engineering (RE) based attacks on integrated circuits. However, the state-of-the-art obfuscation methods use key gates or camouflage existing gates which incur large design overhead and high cost of RE. In this paper, we propose a new obfuscation method based on don't care primitives that not only modifies the sub-circuit functionality but also can be implemented during design process at the cost of little area and delay overhead. Most of the existing obfuscation techniques focus on hiding layout information from circuit attackers, our approach not only obfuscates but alters sub-circuit level functionality in an attempt to make IP piracy difficult and to increase the RE complexity while fulfilling overall circuit specifications. An analysis of RE complexity is provided by functionally obfuscating ISCAS-85 Benchmarks. Our experimental results clearly indicate that significant RE complexity can be achieved at minimal design overhead (average area overhead is 5.436% and average delay overhead is about 7.473%).","PeriodicalId":237290,"journal":{"name":"2016 IEEE International Conference on Information and Automation for Sustainability (ICIAfS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121962782","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}

Failure of the optical fiber causes loss of huge amount of data which can interrupt communication. There are several approaches to ensure network survivability. In survivability, we consider dedicated protection in this paper in which backup paths are configured at the time of establishing connections. If a primary path is failed, the traffic is rerouted through backup path with a short recovery time. In this paper, we investigate the performance by calculating the spectrum efficiency variation for dedicated protection in WDM networks. Spectrum efficiency is calculated by dividing the total traffic bit rate by the total spectrum used. In this paper, we carry out the investigation with detailed simulation experiments on different single-line rate (SLR) scenarios such as 100 Gbps, 400 Gbps, and 1Tbps. In addition, this paper focuses on four standard network topologies which consist of different number of links to identify how the spectrum efficiency varies for each network. Our findings are as follows. (1) Spectrum efficiency for each SLR are almost similar and comparable in all the network topologies. (2) Unlike network topology with low number of links, the spectrum efficiency for network topology with high number of links are higher, therefore, the spectrum efficiency increases when the number of links are increased. (3) The spectrum efficiency is lower when the number of primary links are higher even though in all the network topologies.","PeriodicalId":237290,"journal":{"name":"2016 IEEE International Conference on Information and Automation for Sustainability (ICIAfS)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114353640","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}
