Publication Metadata only Çukurovada Yetiştirilen Amsoy-71 ve Calland Soya Çeşitlerinde Verim ve Yağ Oranının Nükleer Teknikle Geliştirilmesi(TÜBİTAK Yayınları, 1986) Özbek, N.; Atilla, S.; ATAK, ÇİMEN; 6653Publication Metadata only A novel fuzzy TOPSIS method using emerging interval-valued spherical fuzzy sets(2019-06-03) Kahraman, Cengiz; GÜNDOĞDU, FATMA KUTLUAll the extensions of ordinary fuzzy sets with three-dimensional membership functions such as intuitionistic fuzzy sets, second type intuitionistic fuzzy sets (or Pythagorean fuzzy sets) and neutrosophic sets aim at defining the judgments of decision makers/ experts with a more detailed description. As a new extension of intuitionistic fuzzy sets of second type, the emerging spherical fuzzy sets (SFS) have been proposed by Kutlu Gundogdu and Kahraman (2019b). In spherical fuzzy sets, the sum of membership, non-membership and hesitancy degrees must satisfy the condition0 <= mu(2) + v(2) + pi(2) <= 1 in which these parameters are assigned independently. SFS is an integration of Pythagorean fuzzy sets and neutrosophic sets. In this paper, novel interval-valued spherical fuzzy sets are introduced with their score and accuracy functions; arithmetic and aggregation operations such as interval-valued spherical fuzzy weighted arithmetic mean operator and interval-valued spherical fuzzy geometric mean operator. Later, interval-valued spherical fuzzy sets are employed in developing the extension of TOPSIS under fuzziness. Then, we use the proposed interval-valued spherical fuzzy TOPSIS method in solving a multiple criteria selection problem among 3D printers to verify the developed approach and to demonstrate its practicality and effectiveness. A comparative analysis with single-valued spherical TOPSIS is also performed.Publication Metadata only Yöneylem Araştırması ve Endüstri Mühendisliği 32 Ulusal Kongresi(2012) Tarhan, İbrahim Ethem; 114926Publication Metadata only Molecular Mechanics Studies of Antihypertensive Val-Tyr Dipeptide(Asian Journal Of Chemistry, 11/100 Rajendra Nagar, Sector 3,, Sahibabad 201 005, Ghaziabad, India, 2010-01) Akverdieva, G. A.; Godjayev, N. M.; Doğan, N. E.; AKYÜZ, ZEKİ TANIL; AKYÜZ, SEVİM; TR10127; TR111424The spatial structure of anti hypertensive dipeptide,Valine-Tyrosine was investigated within molecular mechanics framework. It ha, been shown that the molecule has such a structural organization which does not exclude the realization of two types of conformation: folded and extended. The energy and geometrical parameters for the optimal conformations of dipeptide are obtained. The electronic characteristics for these structures were analyzed by quantum chemical calculations.Publication Metadata only Mimari Tasarımda Görsel Düşünme(2005) Ertürk, Sevinç; Aslan, Emrah; Ertürk, Zafer; 9446; 7534Publication Metadata only Visual Comfort Efficient Energy Use in Primary School Classrooms(Avery Index, 2011) Kutlu, Rana; 59581Publication Metadata only Bifurcations of Fibonacci generating functions(PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2007-08) Özer, Mehmet; Cenys, Antanas; Hacıbekiroğlu, Gürsel; Akat, Ercüment; Valaristos, A.; Anagnostopoulos, A. N.; POLATOĞLU, YAŞAR; TR2509; TR199370In this work the dynamic behaviour of the one-dimensional family of maps F-p,F-q(x) = 1/(1 - px - qx(2)) is examined, for specific values of the control parameters p and q. Lyapunov exponents and bifurcation diagrams are numerically calculated. Consequently, a transition from periodic to chaotic regions is observed at values of p and q, where the related maps correspond to Fibonacci generating functions associated with the golden-, the silver- and the bronze mean.

Undergraduate students in Turkey are observed to experience difficulties with academic writing as they try to accommodate their existing writing knowledge to the requirements of the new discipline-specific writing and learning situation of tertiary level education. Placing the students at the core of inquiry, the study explored factors influencing students' academic writing practices in English. The participants of the study were nineteen English major undergraduate students studying in Istanbul. The main data were obtained from background questionnaire, semi-structured interviews, document analysis, and were qualitatively analysed. The findings revealed that undergraduate writing is influenced by an array of interrelating educational and contextual factors: (1) the amount and nature of L1 and L2 pre-university writing instruction and experience, (2) students’ perceptions about academic writing and disciplinary-specific text genres, (3) prolonged engagement with the academic context and discourse, and (4) expectations of faculty members. The insights gained from the study provide important implications for reconceptualization of writing instruction in Turkey.Publication Metadata only ENHSA ve Mimarlık Bölüm Başkanları Toplantısı: “Ya Sonra?”(2014) DOSTOĞLU, NESLİHAN; 110251Publication Metadata only Spor Sponsorluğu Sözleşmesi(Seçkin Yayıncılık, 2015-01) Gündoğdu, Fatih; 113726Kanunda düzenlenmemiş olan sponsorluk sözleşmesinin hukuki niteliği üzerine görüş birliği bulunmamaktadır. Hakim görüle göre sponnsorluk sözleşmesi suigeneris yapıda bir sözleşmedir. Bu sözleşmenin esas unsurları destekleme ve tanıtımdır. Spor sponsorluğu sporcuların, grupların, spor etkinlik ya da organizasyonlarının desteklenmesi anlamına gelmekte ve çok farklı şekillerde karşımıza çıkmaktadır. Sponsorluk anlaşmaları en fazla futbol, basketbol, tenis ve motor sporları alanında yapılmaktadır. Spor sponsorluğu bir yana sporcuların desteklenmesine, diğer yandan sponsorların tanınırlıklarının artmasına ve sponsor olunanın pozitif imajında faydalanmasına da hizmet etmektedir. Sponsorluk sözleşmelerinde sponsorun edim yükümü belirli bir paranın ödenmesi veya malzeme temin edilmesi suretiylesporcuların desteklenmesidir. Buna karşın sponsor olunanın edim yükümü ise genellikle, sponsorun tanıtım faaliyetlerine katılmak veya kişilik hakkına müdahale edilmesine katlanmaktır.
