Body mass index, dietary intake and feeding problems of Turkish children with autism spectrum disorder (ASD)
Bicer, A. H.; Alsaffar, Ayten Aylin (Elsevier, 2013-11)The body mass index of 164 children (aged 4–18 years) attending four autism rehabilitation centers in Istanbul, Turkey, was determined and assessed using the BMI-for-age percentile charts by the World Health Organization ... -
Boiling heat transfer enhancement of magnetically actuated nanofluids
Şeşen, M.; Tekşen, Y.; Şahin, B.; Şendur, K.; Mengüç, Mustafa Pınar; Koşar, A. (AIP, 2013)Nanofluids offer a potential breakthrough as next-generation heat transfer fluids since they offer exciting new possibilities to enhance heat transfer performance compared to pure liquids. A major drawback for using ... -
Bose-Einstein correlations of charged hadrons in proton-proton collisions at s√ = 13 TeV
Sirunyan, A. M.; Işıldak, Bora (Springer Nature, 2020-03-03)Bose-Einstein correlations of charged hadrons are measured over a broad multiplicity range, from a few particles up to about 250 reconstructed charged hadrons in proton-proton collisions at <mml:msqrt>s</mml:msqrt> = 13 ... -
Bottom-up approaches to achieve Pareto optimal agreements in group decision making
Sanchez-Anguix, V.; Aydoğan, Reyhan; Baarslag, T.; Jonker, C. (Springer Nature, 2019-11)In this article, we introduce a new paradigm to achieve Pareto optimality in group decision-making processes: bottom-up approaches to Pareto optimality. It is based on the idea that, while resolving a conflict in a group, ... -
Bounding strategies for the hybrid flow shop scheduling problem
Hidri, L.; Haouari, Mohamed (Elsevier, 2011-07-01)In this paper, we investigate new lower and upper bounds for the multiple-center hybrid flow shop scheduling problem. We propose a family of center-based lower bounds as well as a destructive lower bound that is based on ... -
Boza consumption in early-modern Istanbul as an energy drink and a mood-altering substance
Selçuk, Oya İklil (Sakarya Üniversitesi, 2016-04-01)The consumption of substances such as coffee is known to have gained popularity in the early-modern period along with increased urbanization and the proliferation of public places such as coffeehouses, and bathhouses in ... -
A branch-and-cut algorithm for solving the non-preemptive capacitated swapping problem
Erdoğan, Güneş; Cordeau, J.-F.; Laporte, G. (Elsevier, 2010-08-06)This paper models and solves a capacitated version of the Non-Preemptive Swapping Problem. This problem is defined on a complete digraph , at every vertex of which there may be one unit of supply of an item, one unit of ... -
A branch-and-cut algorithm for the Steiner tree problem with delays
Leggieri, V.; Haouari, Mohamed; Triki, C. (Springer Science+Business Media, 2012-12)In this paper, we investigate the Steiner tree problem with delays, which is a generalized version of the Steiner tree problem applied to multicast routing. For this challenging combinatorial optimization problem, we present ... -
A branch-and-price-and-cut method for computing an optimal bramble
Sonuç, Sibel Bilge; Smith, J. C.; Hicks, I. V. (Elsevier, 2015)Given an undirected graph, a bramble is a set of connected subgraphs (called bramble elements) such that every pair of subgraphs either contains a common node, or such that an edge ( i , j ) exists with node i belonging ... -
A branch‐and‐cut approach for the least cost influence problem on social networks
Danış, Dilek Günneç; Raghavan, S.; Zhang, R. (Wiley, 2020-07)This paper studies a problem in the online targeted marketing setting called the least cost influence problem (LCIP) that is known to be NP-hard. The goal is to find the minimum total amount of inducements (individuals to ... -
Bringing sustainability to the heart of a university through teaching, research and service
Gençtürk, Esra; Mengüç, Mustafa Pınar (EDP Sciences, 2018)In this short paper, we summarize our targeted efforts at Ozyegin University in Istanbul, Turkey for establishing a sustainable research, teaching and learning environment. The University is striving to have highest level ... -
Build-to-order meets global sourcing: planning challenge for the auto industry
Matoğlu, Melda Örmeci; Vande Vate, J. (Springer, 2011)Auto manufacturers today face many challenges: The industry is plagued with excess capacity that drives down prices, international competitors are seizing share at both ends of the market and consumers are well informed ... -
Building in extraterrestrial environments: t-brick shell
Yazıcı, Sevil (American Society of Civil Engineers, 2018-03)Space exploration focuses on new technologies to search the unknown. It has been used to investigate possibilities for the creation of human colonies in extraterrestrial environments. Current projects concerning space ... -
Building with bricks and mortar: the revenue impact of opening physical stores in a multichannel environment
Pauwels, Koen Hendrik; Neslin, S. A (Elsevier, 2015-06)A crucial decision firms face today is which channels they should make available to customers for transactions. We assess the revenue impact of adding bricks-and-mortar stores to a firm's already existing repertoire of ... -
Cache replacement scheme based on sliding window and TTL for video on demand
Raouf, Amir Hossein Fahim; Abouei, J. (IEEE, 2018-09-25)In this paper, we propose a novel two-phased cache replacement algorithm based on the dataset obtained from a typical wireless mesh network. In the first phase, we aim to make a trade-off between the networks resources and ... -
Calibrating artificial neural networks by global optimization
Pinter, Janos D. (Elsevier, 2012-01)Artificial neural networks (ANNs) are used extensively to model unknown or unspecified functional relationships between the input and output of a “black box” system. In order to apply the generic ANN concept to actual ... -
Calibrating artificial neural networks by global optimization
Pinter, Janos D. (2010-07)An artificial neural network (ANN) is a computational model − implemented as a computer program − that is aimed at emulating the key features and operations of biological neural networks. ANNs are extensively used to model ... -
