(Taylor & Francis, 2020-08-17)The current study examines the contributions of family context (e.g. life events, home environments) to low-income preschool children’s self-regulation (behaviour regulation and executive function) in the United States and ... -
Fanning the flames? How media coverage of a price war affects retailers, consumers, and investors
Heerde, H. J. van; Gijsbrechts, E.; Pauwels, Koen Hendrik (American Marketing Association, 2015-10)This article explores how media coverage of a price war affects customer, retailer, and investor reactions over time. Using data covering a Dutch supermarket price war (2003–2005), the authors find that price reductions, ... -
FASStR: A framework for ensuring high-quality operational metrics in health care
Torabi, E.; Çayırlı, Tuğba; Froehle, C. M.; Klassen, K. J.; Magazine, M.; White, D. L.; Ward, M. J. (Managed Care & Healthcare Communications, LLC, 2020-06)OBJECTIVES: Poorly defined measurement impairs interinstitutional comparison, interpretation of results, and process improvement in health care operations. We sought to develop a unifying framework that could be used by ... -
Fast and efficient circuit topologies for finding the maximum of n k-bit numbers
Yüce, B.; Uğurdağ, Hasan Fatih; Gören, S.; Dündar, G. (IEEE, 2014-08-01)Finding the value and/or index of the maximum (or minimum) element of a set of n numbers (each with k-bits) is a fundamental arithmetic operation and is needed in many applications. This paper proposes several maximum-finder ... -
A fast circuit topology for finding the maximum of n k-bit numbers
Yuce, B.; Uğurdağ, Hasan Fatih; Gören, S.; Dundar, G. (IEEE, 2013)Finding the value and/or address (position) of the maximum element of a set of binary numbers is a fundamental arithmetic operation. Numerous systems, which are used in different application areas, require fast (low-latency) ... -
Fast parallel prefix logic circuits for n2n round-robin arbitration
Uğurdağ, Hasan Fatih; Baskirt, O. (Elsevier, 2012-08)An n2n round-robin arbiter (RRA) searches its n inputs for a 1, starting from the highest-priority input. It picks the first 1 and outputs its index in one-hot encoding. RRA aims to be fair to its inputs and maintains ... -
Fast, secure, and remote multiboot of FPGAs
Yıldız, Abdullah (2012-09)The purpose of this thesis is to develop an efficient framework to implement secure FPGA-based (Field Programmable Gate Array) systems. An FPGA is a reconfigurable device that has the ability to adapt the hardware during ... -
Fast-decodable MIMO HARQ systems
Hosseini, S. S.; Abouei, J.; Uysal, Murat (IEEE, 2015-05)This paper presents a comprehensive study on the problem of decoding complexity in a Multi-Input Multi-Output (MIMO) Hybrid Automatic Repeat reQuest (HARQ) system based on Space-Time Block Codes (STBCs). We show that there ... -
Fault masking as a service
Gülcü, Koray (2013-01)In service-oriented architectures, composite services depend on a set of partner services to perform their tasks. These partner services may become unavailable due to system and/or network faults, leading to an increased ... -
Feature-based rationale management system for supporting software architecture adaptation
Tekinerdoğan, B.; Sözer, Hasan; Akşit, M. (World Scientific Publishing Co., 2012-11)Each software architecture design is the result of a broad set of design decisions and their justifications, that is, the design rationale. Capturing the design rationale is important for a variety of reasons such as ... -

Mungan, Devin; Ferazoğlu, Gülden; Sunay, Mehmet Oğuz (IEEE, 2012)In this paper, it is proposed that in order to guarantee a certain level of Quality of service (QoS) for different applications in a femtocell network, it is necessary to use application-based scheduling in femtocell access ... -
Field programmable gate arrays implementation of dual tree complex wavelet transform
Canbay, F.; Levent, Vecdi Emre; Serbes, G.; Goren, S.; Aydin, N. (IEEE, 2015)Due to the inherent time-varying characteristics of physiological systems, most biomedical signals (BSs) are expected to have non-stationary character. Therefore, any appropriate analysis method for dealing with BSs should ... -
