Article Citation - WoS: 1Life Cycle Assessment of Tomato Paste Production: a Case Study(Pamukkale Unıv, 2024) Üçtuğ, Fehmi Görkem; Tekin, Zehranur; Dayıoglugil, Zeynep; Ulusoy, Ercan; Oktaylar Keyik, Şule; Keyik, Sule OktaylarThis study involves the cradle -to -gate life cycle assessment of tomato paste production in Turkey. All the data was obtained from a large-scale production company located in north-west Turkey in 2020. CCaLC software with Ecoinvent2 database alongside CML2001 method was used for the analysis and the following impacts were taken into account: acidification potential, carbon footprint, eutrophication potential, human toxicity potential, ozone layer depletion potential, and photochemical smog potential. Functional unit was chosen as 1 kg of tomato paste sold in glass jars. The results show that the biggest contributor to environmental impacts was the raw material supply stage, mainly due to fungicide (for agriculture) and metal (for packaging) use. Energy required for agricultural and production processes were also found to have significant effects of the impacts. The results were found to be in very good consistency with earlier literature. Using photovoltaic panels for meeting 10% of the electricity demand of agricultural and production processes or utilizing tomato harvesting waste to produce biomethane were found to have almost no positive effects as far as impact reduction is concerned. These results show that switching to organic farming seems to be essential if environmental impacts of processed food products such as tomato paste are to be reduced.Article Some New Approximate Solutions in Closed-Form To Problems of Nanobars(2021-12-20) Eroğlu, UğurcanFollowing recent technological advancements, a great attention has been paid to the mechanical behaviour of structural elements of nanosize. In this study, some solutions to mechanical problems of bars of nanosize are examined using Eringen’s two-phase nonlocal elasticity. Assuming the fraction coefficient of nonlocal part of the material is small, a perturbation expansion with respect to it is performed. With this procedure, the original nonlocal problem is broken into a set of local elasticity problems. Solutions to some example problems of nanobars are provided in closed-form for the first time, and commented on. The new solutions provided herein may well serve for benchmark studies, as well as identification of material parameters of nano-sized structural elements, such as carbon nanotubes.Article Citation - Scopus: 9İplik Karakteristiği ve Hata Tespiti Üzerine Görüntü İşleme Uygulamaları(Chamber of Textile Engineers, 2019-12-31) Gültekin, Elif; Dulger, Lale Canan; Çelik, Halil İbrahim; Sünbül, Halil İbrahim; Kani, HarunMakine görüşü ve otomasyon teknolojilerindeki yeni gelişmeler, üretim hattının her aşamasında daha hassas bir süreç kontrolü ve kalite denetimi sağlamaktadır. Endüstri 4.0 ve Görüntü İşleme teknikleri, son on yılda tekstil endüstrisindeki birçok alanda kullanılmıştır. Görüntü işleme teknikleri, tekstil endüstrisinde, elyaf, iplik ve kumaş özelliklerinin gelişmiş doğruluk ve daha hızlı sonuçlarla otomatik olarak algılanmasında da kullanılmıştır. Bu çalışmada, iplik bobini ve kumaş abraj kusurunun otomatik belirlenmesi için bir makine görme sistemi sunulmuştur. Prototip sistem bileşenleri açıklanmıştır. Geliştirilen görüntü işleme algoritması abraj hatası içeren farklı bobin ve kumaş örneklerine uygulanır. Oluşturulan yapay görme sisteminin başarısı burada tartışılmaktadır
