Students often tend to experience difficulty in the application of knowledge learnt, as they seem to be accustomed to learning theory by rote and simply repeating it for the purpose of assessments. A somewhat different approach has been taken by the Design and Manufacturing Engineering (DME) Unit at the University of Trinidad and Tobago. In its BASc and MSc offerings, the DME Unit has made the application of knowledge learnt in the various courses offered a key feature of its programmes. The focus of this paper will be on the MSc programmes offered by the Unit. The DME Unit currently offers two Masters programmes, one which focuses on management (Innovation, Manufacturing Management and Entrepreneurship – IMME) and another which focuses on design (Innovative Design and Entrepreneurship – IDE). These programmes are designed with a view to achieving several outcomes, including fostering the entrepreneurial spirit of students with the intention that they will start businesses at the end of their course of study, thereby commercialising any product or service they develop during the programme; developing their management capabilities, which prepares them for higher level positions and responsibilities at their places of work; immersing students into real-time, problem-based scenarios at companies over the period of a semester to allow them to act as consultants in a work environment different to their own; and nurturing their engineering design capabilities for new product development, with the intention that any such design produced will eventually be commercialised. In light of these outcomes, both programmes share common features in the courses that are covered. Such courses focus on management, entrepreneurship, business development and industry immersion. This paper will highlight the successes of this approach in both programmes.","PeriodicalId":206492,"journal":{"name":"Proceedings of the International Conference on Emerging Trends in Engineering & Technology (IConETech-2020)","volume":"14 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120931453","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}

Seismic stations continuously gather data without the necessity of the occurrence of an event. The gathered data is processed by the model to forecast the occurrence of earthquakes. This paper presents a model to forecast earthquakes using Parallel processing. Machine Learning is rapidly taking over a variety of aspects in our daily lives. Even though Machine Learning methods can be used for analyzing data, in the scenario of event forecasts like earthquakes, performance of Machine Learning is limited as the data grows day by day. Using ML alone is not a perfect solution for the model. To increase the model performance and accuracy, a new ML model is designed using parallel processing. The drawbacks of ML using central processing unit (CPU) can be overcome byGraphic Processing unit (GPU) implementation, since the parallelism is naturally provided using framework for developing GPU utilizing computational algorithms, known as the Compute Unified Device Architecture (CUDA). The implementation of hybrid state vector machine (H-SVM) algorithm using parallel processing through CUDA is used to forecast earthquakes. Our experiments show that the GPU based implementation achieved typical speedup values in the range of 3-70 times compared to conventional central processing unit (CPU). Results of different experiments are discussed along with their consequences.","PeriodicalId":206492,"journal":{"name":"Proceedings of the International Conference on Emerging Trends in Engineering & Technology (IConETech-2020)","volume":"10 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":"127115243","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}

An alternative to not so clean source Coal appears to be Nuclear Power and this option can supplement and supplant our energy needs despite several concerns from various sources post-Fukushima Nuclear accident. This paper carries out a detailed LCA study of Nuclear based Electric Power Generation System with a wider scope that encompasses the waste disposal and spent fuel reprocessing phases, is modelled and run on SimaPro 9.0.0.48 LCA software with ECOINVENT 3.0 as database. This study also covers the all-important Inventory Analysis for the inputs used, raw material extracted and residuals consequently released to the environment. The results are expressed in terms of pre-defined energy metrics such as ERR and EPBT. Further, the study covers the environmental impact assessment category such as GWP and finally the results are presented with a kWh of electricity produced by this option as a functional unit. These investigations help energy planners and policymakers to compare various power generating options and justify the alternatives to meet future demand for electricity in a cleaner and more sustainable manner by keeping the spirit of Paris Climate Agreement in mind.","PeriodicalId":206492,"journal":{"name":"Proceedings of the International Conference on Emerging Trends in Engineering & Technology (IConETech-2020)","volume":"2 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":"129766313","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}

Chowdary","doi":"10.47412/hexu4041","DOIUrl":"https://doi.org/10.47412/hexu4041","url":null,"abstract":"Design complexity in additive manufacturing (AM) is a current issue in the research community, fueled by the well-known phrase “complexity for free”. This statement has promoted the assumption that complex geometries may be achieved without any increase in the cost of production. However, recent research has indicated that increasing shape complexity produces an increase in production costs for the material extrusion process. This challenges the mainstream assumption that AM technologies provide ‘complexity for free’. The AM community requires further investigation of design complexity and its impact on sustainable production when used as a Design for Manufacturing (DfM) tool. This paper proposes a data-driven method which uses design complexity as an AM performance indicator for the material extrusion process. The manufacturing responses included build time (BT), dimensional accuracy (DA) and complexity index (CI). Design space exploration of an automotive air filter model was achieved by varying five critical design features which impact complexity. The study utilized a Face Centered Central Composite Design (FCCCD) of three levels for the design features, comprising 32 experimental models. The optimal model was manufactured based on multi-objective optimization using the MINITAB© response optimizer. This method exploits the design features to achieve target performance and manufacturability. The viability of design complexity as an AM performance indicator was discussed leading to three major improvements to the Product Design and Development (PDD) process for AM. The proposed improvements have the potential to reduce process times and minimize resources, providing a sustainable AM approach for developing regions.","PeriodicalId":206492,"journal":{"name":"Proceedings of the International Conference on Emerging Trends in Engineering & Technology (IConETech-2020)","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":"129096981","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 describes the case of one such plant in Jamaica recovering 350 m 3 /h of digester regenerative condensate. The steam and power for the alumina refinery is supplied by a cogeneration facility, which has to use a mix of well water and return condensate from the steam users in the alumina production process. The refinery produces alumina from Jamaican bauxite ore, using the Bayer process. This process includes the digestion of bauxite with sodium hydroxide at 135 deg.C, hence the requirement for both steam and power. In the course of this extraction, large quantities (350 m 3 /h) of digester and evaporator condensate are produced. In view of the limited liquid discharges permitted from the site, this condensate was stored on site in large ponds, and reused in the process. Pressured from three sides, with a limitation on raw water abstraction from the wells by the Water Resource Authority, a requirement for minimized liquid discharge of wastewater, and high cost of energy there was a need to utilize the regenerative condensate from the digesters and the evaporators as boiler feedwater. Studies carried out by international water treatment companies had concluded that Total Organic Carbon (TOC) would not allow condensate re-use as boiler feedwater, with an attached US$10 million cost for the removal of TOC. Extensive laboratory work and thermodynamic analysis were carried out and the condensate are used as boiler feedwater, without treatment. The avoided cost was US$10 million and energy savings of US$3 million realized.","PeriodicalId":206492,"journal":{"name":"Proceedings of the International Conference on Emerging Trends in Engineering & Technology (IConETech-2020)","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":"114802354","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}

Consequently, chloride content can be dramatically increased without worry for the deterioration of the encased reinforcement in reinforced concretes that utilizes composite rebar and polymeric/ceramic fibres. The production of one tonne of concrete releases 900 kg of CO2 emissions. Reductions in CO2 emissions from concrete production can be achieved through the production of ‘greener’ cements, and utilization of localized aggregate sources. Construction of structures along the coastline provides a unique opportunity for the utilization of beach-sand and brackish water that together can improve the sustainability prospects for construction in these environments. The incorporation into concrete of beach-sand that has been previously excavated is a simple means of reducing reliance on traditional sources of fine aggregate for concrete production. Additionally, the use of brackish water from a nearby estuary has the added benefit of reducing the requirement for potable water. Compressive strength tests were conducted on twenty-two (22) groups of specimens at 7-days, 28-days and 42-days. Water-to-cement ratios (w:c) of 0.37, 0.39, 0.43 and 0.45 were employed. Analysis showed that at 0.37 w:c, batches that utilized beach-sand and brackish water, beach-sand and potable water, concreting-sand and brackish water were comparable to those produced with concreting-sand and potable water at about 40MPa.","PeriodicalId":206492,"journal":{"name":"Proceedings of the International Conference on Emerging Trends in Engineering & Technology (IConETech-2020)","volume":"24 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":"133943883","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}

Navigation performance of the Pioneer robot platform used the following metrics: Average Cycle Time per simulation run; Average Wall Contact per cycle; and Average Shock Treatment Activation per simulation run. Two ultrasound, or US, configurations were used while the robot navigated in either the ‘preconfigured-reflexes only’ mode or the ‘Braitenberg Obstacle Avoidance’ mode. Results from the “16 sensor” US configuration was generally found to be significantly different from that of the “8 sensor” configuration, independently of obstacle avoidance considerations. Robot performance, when subject to the Braitenberg Obstacle Avoidance algorithm, was also found to be significantly different from ‘preconfigured-reflexes only’ performance, regardless of US configuration. The difference in Shock Treatment and the Average Wall Contact, observed between the “16 sensor” US setting and the “8 sensor” configuration for the ‘Braitenberg Obstacle Avoidance’, are likely to be due to the coefficient values adopted for the rear US sensors together with robot position at experiment start. The use of this environment to enable statistical analysis of results, to determine significant difference in obstacle avoidance performance, validates its usefulness as a tool for CFS Autonomy validation.","PeriodicalId":206492,"journal":{"name":"Proceedings of the International Conference on Emerging Trends in Engineering & Technology (IConETech-2020)","volume":"07 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":"128848461","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}
