In this study, to aim to decrease harmful exhaust emissions sunflower oil methyl ester was mixed volumetrically with diesel fuel in %25 proportion. The mixture was tested in four stroke, air cooled, direct injection diesel engine with single cylinder in different speed (rpm) and emission values were measured. These values were compared with the ones for diesel fuel. The results showed that the mixture of sunflower oil methyl ester and diesel fuel gave a power and torque close to the values obtained from the diesel fuel and the amounts of pollutants decreased. At the maximum torque, amount of CO and NOx decreased 21% and 11% respectively. Similarly, they decreased 7% and 12% at maximum power speed. As a result, considering the exhaust gas emissions it was seen that sunflower oil methyl ester and diesel fuel mixture could be used as an alternative fuel in a diesel engine.

However, only a limited number of studies consider the uncertainty in the assembly lines. In this research, a robust formulation is developed for the addressed problem under task time uncertainty by focusing on the heterogeneity inherent of workers. The worker resources are not the same in terms of either skills or skill levels. Therefore, it is plausible to investigate the manufacturing system from this perspective to provide managerial insights regarding the performance metrics, such as the total cost, number of stations. Besides, the uncertainty of processes in a manufacturing system must be considered to improve system performance. Since robust optimization is a powerful technique to overcome uncertainty, the robust approach is employed in this study. First, the UALB problem is presented and followed by that the robust counterpart of this model is provided. The optimal results are obtained for different parameter levels after solving the model. The analysis of the results is made through real data provided by a water-meter assembly line.","PeriodicalId":6817,"journal":{"name":"4th International Symposium on Innovative Approaches in Engineering and Natural Sciences Proceedings","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78407423","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}

Milyarlarca insana ulaşan spor ise geniş kitleleri bir araya getirmekte ve sporun endüstriyelleşmesiyle beraber alınan haz da değişmektedir. İnsan hayatında bu kadar önemli yeri olan teknoloji ve sporla birlikte sosyal medya kullanımı da spor özelinde oldukça önemli olmuştur. İnsanlar yeni iletişim teknolojileri sayesinde izlediği spor karşılaşmalarıyla ilgili düşüncelerini ve duygularını takipçileriyle paylaşma isteği duyarken ana akım medya ise tekelini ve gücünü kaybetmeye başlamıştır. Etkileşimin böylesine önemli bir unsuru olan spor, günümüzde pazarlama stratejileri açısından sosyal medyasız mümkün olmamaktadır. Televizyon izlenmesinin ve gazete okunma sayısının büyük bir hızla düştüğü son yıllarda sosyal medyanın tartışmasız yükselişi onu kurumsal iletişim stratejileri arasında birinci sıraya getirmiştir. Sadece markalar için değil, spor kulüplerinin de bu yolla taraftarlarına ve takipçilerine ulaşma amacı, olumlu geri dönüşlere neden olmaktadır. Bu yolla taraftarına çok hızlı ve anlık olarak ulaşabilen kulüpler, yaptıkları paylaşımlarla da takımlarıyla ilgili bilgileri en hızlı ve doğru şekilde paylaşmaktadır. Bu nedenle de aktif olarak sosyal medya paylaşımı yapan spor kulüpleri takipçileriyle etkileşim halinde olarak onların sadakatini daha da artırmaktadır. Bu bağlamda araştırmanın konusunu, Türkiye’deki basketbol spor kulüplerinin sosyal medya kullanımları oluşturmaktadır.

Nowadays, companies need to adapt to continuous change, design and manufacture fast products in order to be more efficient and productive in competitive environment and to survive in the market. TRIZ helps to solve problems faster with the tools that it offers. TRIZ, which was developed by Altshuller in 1946 and started to be used in Russia since 1950s, started to be learned and used in other countries in the early 1990s. TRIZ, which is used in various fields today, is also applied in the solution of aviation problems. Military aircrafts are usually equipped with pylons to carry munitions. Pylons are the equipment that allow the munitions carried in the military aircraft to be connected to, transported to and released from the military aircraft. The releasing mechanisms are hanger equipments which ensures that the munition carried can be safely separated from the military aircraft when required. In this study, the patents which were published in the literature about release mechanisms will be examined and certain problems in releasing mechanisms will be solved using Technical Contradictions. TRIZ solutions will be validated with existing patents and solutions for obtaining new patent ideas will be presented.","PeriodicalId":6817,"journal":{"name":"4th International Symposium on Innovative Approaches in Engineering and Natural Sciences Proceedings","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85113260","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}
