2D modeling temperature development of mass concrete structures at early age - 2018
No full textAlper Yıkıcı (MEF Author)In this paper, a 2D finite volume analysis methodology was used to predict temperature development within three different bridge pier caps. MATLAB® was employed to generate a program that solves the governing heat transfer equation where development of thermo-physical concrete properties was defined as a function of degree of hydration. The rate of heat generation was obtained experimentally via adiabatic calorimetry and the activation energy was determined following the ASTM C 1074 procedure to implement equivalent age concept. 2D finite volume analysis results were presented in comparison with the recorded concrete temperatures from the field. Accordingly, temperature time histories at the center and the side surface of the bridge pier caps were predicted reasonably well using the concrete mixture information and the measured concrete hydration properties.WOS:0005502533000742-s2.0-85134814600Conference Proceedings Citation Index- ScienceProceedings PaperHaziranYÖK - 2017-1

Diffraction modeling by a soft-hard strip using finite-difference time-domain method
No full textUslu, Mehmet Alper (Dogus Author)Diffraction by a strip with one face soft and the other face hard boundary condition is modeled numerically using finite-difference time-domain method, and the results are compared to the method of moments, which was validated against physical theory of diffraction
Future talk: parenting for a digital future for young people with a disability
No full textMeryl Alper says the relationship between disabled children and the digital future is a complicated one. In this post, she looks at one U.S.-American family’s story and discusses how it’s characteristic of many parent’s talk of the future, digital media and its role in their disabled child’s paths and plans. She is a PhD candidate at the Annenberg School for Communication and Journalism at the University of Southern California, and author of Digital youth with disabilities. Meryl’s work focuses on the social and cultural implications of communication technologies, with a focus on disability and digital media, children and families’ media use and mobile communicatio

Fikirleriyle Türkçü nesillerin doğması ve yetişmesinde önemli etkisi olan Hüseyin Nihal Atsız'ın tarih alanında yapmış olduğu çalışmalar, bugün birçok araştırmacı tarafından kaynak olarak kullanılır. Edebî sahada vermiş olduğu eserlerle özgünlüğünü ortaya koyan Atsız, Türk edebiyatının önemli simalarındandır. Çalışmamızın ilk bölümünde Hüseyin Nihal Atsız'ın hayatına değinildi. İkinci bölümde yazarın Bozkurtların Ölümü, Bozkurtlar Diriliyor, Deli Kurt, Ruh Adam, Dalkavuklar Gecesi ve Z Vitamini romanlarındaki olaylara kısaca yer verildi. Üçüncü, dördüncü ve beşinci bölümlerde ise yazarın romanlarında tespit ettiğimiz siyasî, sosyal ve tarihî meseleler ayrı başlıklar altında incelendi.Huseyin Nihal Atsiz is a Turkish intellectual who made a mark in the period he lived, with his life, ideas and works. Huseyin, who has an important influence on the birth and development of Turkish generations with his ideas, is used by many researchers as a source for his studies in the field of history. Atsiz is a prominent figure of Turkish literature. In the first part of our study, the life of Huseyin Nihal Atsiz was mentioned. In the second chapter, the author's story of "Bozkurtların Ölümü, Bozkurtlar Diriliyor, Deli Kurt, Ruh Adam, Dalkavuklar Gecesi and Z Vitamini" novels was given. In the third, fourth and fifth chapters, the social, political and historical issues identified in the novels of the author were analyzed under different headings
EMC/EMI problems and diffraction modeling: Finite difference time domain vs. method of moments
No full textUslu, Mehmet Alper (Dogus Author) -- Sevgi, Levent (Dogus Author) -- Conference full title: 2014 International Symposium on Electromagnetic CompatibiIity, EMC 2014; Hitotsubashi Hall (National Center of Sciences)Tokyo; Japan; 12 May 2014 through 16 May 2014.Edge and/or tip diffraction has long been investigated. Early attempts were analytical and called High Frequency Asymptotics (HFA). With the use of computers, numerical approaches have also appeared. In this study, two powerful numerical models, Method of Moments (MoM) and Finite Difference Time Domain (FDTD), are used in diffraction modeling on the canonical wedge scattering problem.IEEE Antennas and Propagation Societ
