An interactive and cooperative university - industry partnership can increase the quality of life and reduce the risk of disaster. Here the fields where universities consider the involvement of industry are recognized (e.g., fundamental and applied research, development, production life cycle and such). There is a recognized need for the private sector to engage the research community in the context of disaster resilience research to tackle disaster risk. The definition of “industry” in this research is deliberately vague to allow exploration of what useful collaborations “industries” can develop with universities for disaster management research (here collaborations mean different life cycle interactions). There is the need for an integrated multiple criteria decision analysis to mitigate the effects of disaster on the built environment at three levels: the micro (research and innovation performance, transfer and absorptive capacity, technology development), meso (institutional arrangements, communication network, local and indigenous rules) and macro (supply and demand, regulations, financing, taxes, culture, traditions, market, climate, political, demographic, technology) levels. Disaster management involves numerous aspects for consideration in addition to making economic, political and legal/regulatory decisions. These must include social, cultural, ethical, psychological, educational, environmental, provisional, technological, technical, organizational and managerial aspects. This research produced a model and a system for integrated analysis of the iterative life cycle of university-industry partnerships. The model and the system make it possible to perform multi-variant design and multiple criteria assessment of alternative university-industry partnership life cycles, calculate their market and investment value, conduct online negotiations, and select options that offer the best efficiency.</p></div>","PeriodicalId":20470,"journal":{"name":"Procedia Engineering","volume":"212 ","pages":"Pages 270-277"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proeng.2018.01.035","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91481831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biodiesel has gained increasing attention as an alternative to fossil fuels for reducing the greenhouse gas emissions from the transportation sector. Yellow oleander (<em>Thevetia peruviana</em>) grows extensively in gardens as a decorative tree throughout Sri Lanka. The plant is a potential source of feed stock for biodiesel production as it produces fruit with two seeds with higher oil content as 49.6% (db) and it is a non-utilized oil crop without any economic value. The objective of this study is to produce biodiesel by transesterifying using extracting oil and to determine its properties. Yellow oleander oil with proper free fatty acid limit was pretreated with NaOH as catalyst and anhydrous methanol amount as 20% of oil volume. The produced yellow oleander methyl ester was characterized. It was observed as gross calorific value as 37.74 MJ/kg (ASTM D 240), flash point of 118°C (ASTM D 93), Kinematic viscosity at 40°C of 5.96 mm2/s (ISO 3105:1976), specific gravity of 0.8874 (ASTM D 1298) and density at 15°C of 887 kg/m3.

The choice of the most suitable model depends on the fire source location. For the longitudinal temperature distribution along the ceiling, if the disturbance region is far away from the fire source, the temperature profile can be well correlated by the Li’s model. However, if the disturbance region is close to the fire source, the models proposed by Li and He should be used together.

Its effectiveness relies on the proper allocation of each kind of relief good amongst the demand areas on a given frequency. Because these operations involve a limited supply of relief goods, vehicles, and time, it is important to optimize these operations to satisfy as much demand as possible. The study aims to create a linear programming model which provides a set of recommendations on how the current disaster relief supply chain may be carried out, specifically on how distribution operations allocate supplies among demand nodes as well as the routes taken in a day. The areas visited per day would depend on the capacity of the vehicle fleet as well as on the routes that can be used. This linear programming model will use Balcik’s last mile distribution model, while modifying it for the relief operations in the Philippines. The model minimizes routing costs as well as penalty costs for unsatisfied demands. Map data is used for determining routes and historical data from previous disasters are used to determine the supply and demand for relief goods while providing a benchmark for results. The model produces recommendations for (1) Demand node schedule, (2) Best route for schedule, (3) Relief good allocation, and (4) Operational costs. It also provides the computational backbone for relief distribution decisions in the Philippines, allowing for more optimal operations in the future.</p></div>","PeriodicalId":20470,"journal":{"name":"Procedia Engineering","volume":"212 ","pages":"Pages 133-140"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proeng.2018.01.018","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86251863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
