Editorial - Preface to the Special Issue on Numerical Techniques Meet with OR

Gurbuz, Burcu
Weber, Gerhard-Wilhelm
This special issue of the Foundations of Computing and Decision Sciences, titled "Numerical Techniques Meet with OR", is devoted to the numerical techniques and their applications in real-world phenomena. The special issue and its editorial present numerical algorithms as they meet with different research topics such as, e.g., from operational research, supply chain management, geometrical structures and Covid-19 effects on financial applications. Besides, the special issue covers instructional information about numerical techniques which are useful for OR research problems and real-world applications on such issues.


An Introduction to the Special Issue on Numerical Techniques Meet with OR - Part II
Gurbuz, Burcu; Weber, Gerhard-Wilhelm (2021-09-01)
The special issue: "Numerical Techniques Meet with OR" of the Foundations of Computing and Decision Sciences consists of two parts which are of the main theme of numerical techniques and their applications in multi-disciplinary areas. The first part of this special issue was already collected in the FCDS Vol. 46, issue 1. In this second part of our special issue editorial, a description of the special issue presents numerical methods which can be used as alternative techniques for Scientific Computing and l...
Almost periodic solutions of recurrently structured impulsive neural networks
Top, Gülbahar; Akhmet, Marat; Department of Mathematics (2022-3-28)
This thesis aims to conduct detailed and precise neural networks research with impulses at nonprescribed moments in terms of periodic and almost periodic solutions. Most of the actions in nature modeled by neural networks involve repetitions. Hence periodic and almost periodic motions become crucial. So in this thesis, the existence, uniqueness, and stability of the periodic and almost periodic motion are served for the neural networks with prescribed and nonprescribed impacts. This impulsive system is a n...
Rigorous Analysis of Double-Negative Materials with the Multilevel Fast Multipole Algorithm
Ergül, Özgür Salih (2012-02-01)
We present rigorous analysis of double-negative materials (DNMs) with surface integral equations and the multilevel fast multipole algorithm (MLFMA). Accuracy and efficiency of numerical solutions are investigated when DNMs are formulated with two recently developed formulations, i.e., the combined tangential formulation (CTF) and the electric and magnetic current combined-field integral equation (JMCHE). Simulation results on canonical objects are consistent with previous results in the literature on ordin...
Investigation of undergraduate students' mental models about the quantization of physical observables
Didiş, Nilüfer; Eryılmaz, Ali; Erkoç, Şakir; Department of Secondary Science and Mathematics Education (2012)
The purpose of this research is to investigate undergraduate students’ mental models about the quantization of physical observables. The research was guided by ethnography, case study, and content analysis integrated to each other. It focused on second-year physics and physics education students, who were taking the Modern Physics course at the Department of Physics, at Middle East Technical University. Wide range of data was collected by interview, observation, test, diary, and other documents during 2008-...
Students understanding of limit concept: an apos perspective
Çetin, İbrahim; Özden, Yaşar; Department of Computer Education and Instructional Technology (2009)
The main purposes of this study is to investigate first year calculus students’ understanding of formal limit concept and change in their understanding after limit instruction designed by the researcher based on APOS theory. The case study method was utilized to explore the research questions. The participants of the study were 25 students attending first year calculus course in Middle East Technical University in Turkey. Students attended five weeks instruction depending on APOS theory in the fall semester...
