A finite-volume front-tracking method for computations of multiphase flows in complex geometries
(Frontiers, 2005) N/A; Department of Mechanical Engineering; Muradoğlu, Metin; Faculty Member; Department of Mechanical Engineering; College of Engineering; 46561
A finite-volume/front-tracking (FV/FT) method is developed for computations of multiphase flows in complex geometries. The front-tracking methodology is combined with a dual time-stepping based FV method. The interface between phases is represented by connected Lagrangian marker points. An efficient algorithm is developed to keep track of the marker points in curvilinear grids. The method is implemented to solve two-dimensional (plane or axisymmetric) dispersed multiphase flows and is validated for the motion of buoyancy-driven drops in a periodically constricted tube with cases where drop breakup occurs.

A low-SWaP, low-Cost transceiver for physically secure UAV communication with visible light
(Springer, 2020) Department of Electrical and Electronics Engineering; Ergen, Sinem Çöleri; Soner, Burak; Faculty Member; Department of Electrical and Electronics Engineering; College of Engineering; Graduate School of Sciences and Engineering; 7211; N/A
Unmanned aerial vehicles (UAV) are expected to utilize optical wireless technologies alongside radio frequency technologies for reliable, secure and high bandwidth communications. While terrestrial and atmospheric laser-based solutions in the past have achieved physically secure communication with very complex beam tracking/pointing mechanisms with large and costly telescopes, such systems are neither suitable nor necessary for medium-range (<100 m) commercial UAV communications. With the proliferation of low-cost solid-state lighting equipment and visible band photodetectors, visible light communications (VLC) offer a low-size-weight-and-power (SWaP) and low-cost solution. This paper presents a novel low-SWaP and low-cost transceiver for physically secure VLC in medium-range commercial UAV applications. Full implementation details for a proof-of-concept prototype built completely with off-the-shelf components are also reported.

A metal workshop? Multi-hollow anvils at Taştepe obası in southeastern Konya
(Brill, 2017) N/A; Department of Archeology and History of Art; Maner, Çiğdem; Faculty Member; Department of Archeology and History of Art; College of Social Sciences and Humanities; 104427
During the first campaign of the Konya Ereğli Survey Project (keyar) in 2013, c. 12 km north of the Bolkar Mountains, a site called Taştepe Obası just north of the village of Çayhan was surveyed. In between domestic houses and in the field of Taştepe Obası, four large stones with man-made small circular depressions were discovered. These rocks, known as multi-hollow anvils or multi-hollow mortars, are important indications that metal ores were dressed here. The proximity to the metal-rich Bolkar Mountains might indicate the presence of a metal workshop. Very similar multi-hollow anvils have been discovered in the vicinity of the Kestel mine, where they were used for ore dressing of cassiterite, the first stage in the preparation of the ore for the smelting process. This article will introduce the site of Taştepe Obası and consider it in the context of ancient metal workshops in the region and the mining activities in the Bolkar Mountains.

A multiobjective solution method for radiation treatment planning
(Springer, 2018) Kirlik, Gokhan; Sayin, Serpil; Zhang, Hao Howard; Department of Business Administration; Sayın, Serpil; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 6755
The challenge in radiation treatment planning (RTP) is to ensure delivery of a prescription dose to the tumor while limiting the normal tissue toxicity. One way of dealing with this trade off is to use multiobjective optimization which no longer possesses a unique optimal objective function value. In multiobjective optimization, efficient solutions are used instead of the optimal solution which have the property that no improvement in any objective is possible without sacrificing in at least one other objective. In this study, we use achievement scalarization to obtain efficient solutions, i.e. treatment plans which are efficient, for the RTP. We adapt the parameters of the achievement scalarization to address a solution in a rectangle that is defined by the bounds on the objective functions. For a given set of bounds on each structure of the treatment volume, the formulation is able to attain a treatment plan that targets the bounds. We tested our approach on 10 locally advanced head-and-neck cancer cases. All of the cases include three tumor volumes, primary tumor, high-risk nodal volume, low-risk nodal volume, and five organs-at-risk (OAR), left and parotids, spinal cord, brain stem, oral cavity. We compare the proposed method with multiobjective solution algorithm from the literature and clinical plans. While satisfying the coverage of the target volumes, the proposed algorithm was able to improve the OAR sparing as much as 35%.

A sense of things to come: future research directions in sensory marketing
(Taylor and Francis, 2011) Elder, Ryan S.; Barger, Victor; Caldara, Cindy; Chun, Hae Eun; Lee, Chan Jean; Mohr, Gina S.; Stamatogiannakis, Antonios Adoni; Department of Business Administration; Aydınoğlu, Nilüfer Zümrüt; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 114037
The exciting exploration on sensory marketing presented in this book is just the foundation upon which to build future research. There are myriad unexplored questions and innumerable directions in which to take this research. Our goal in this chapter is not to provide an exhaustive array of these future directions, but rather to stimulate the reader into exploring new ideas. We present possible future directions for each sense individually (vision, audition, smell, touch, taste), and conclude with ideas for future research addressing the interplay among multiple senses within consumer behavior. © 2010 by Taylor and Francis Group, LLC.

A survey of the additive dilogarithm
(Birkhauser, 2021) Department of Mathematics; Ünver, Sinan; Faculty Member; Department of Mathematics; College of Sciences; 177871
Borel’s construction of the regulator gives an injective map from the algebraic K–groups of a number field to its Deligne–Beilinson cohomology groups. This has many interesting arithmetic and geometric consequences. The formula for the regulator is expressed in terms of the classical polyogarithm functions. In this paper, we give a survey of the additive dilogarithm and the several different versions of the weight two regulator in the infinitesimal setting. We follow a historical approach which we hope will provide motivation for the definitions and the constructions.

A systemic approach to impression formation: from verbal to multimodal processes
(Taylor and Francis, 2012) Garrido, Margarida V.; Department of Psychology; Semin, Gün Refik; Researcher; Department of Psychology; College of Social Sciences and Humanities; N/A
The connection between mental and social life remains one of the most intriguing topics in all of psychology. This book reviews some of the most recent advances in research exploring the links between how people think and behave in interpersonal situations. The chapters represent a variety of theoretical orientations, ranging from evolutionary approaches through cognitive and affective theories, all the way to considering social and cultural influences on the relationship between social cognition and interpersonal behavior. Given its breadth of coverage, this volume is useful both as a basic reference book and as an informative textbook for advanced courses dealing with social cognition and interpersonal behavior. The main target audience comprises researchers, students, and professionals in all areas of the social and behavioral sciences, including social, cognitive, clinical, counseling, personality, organizational, forensic, and applied psychology, as well as sociology, communication studies, and social work. Written in a readable yet scholarly style, this volume serves as an engaging overview of the field for students in courses dealing with social cognition and social interaction at undergraduate and graduate levels.

A tale of two cities: Thebes and Chalcis in a world of change (ninth to fifteenth centuries)
(Taylor and Francis, 2021) Department of Archeology and History of Art; Kontogiannis, Nikolaos; Faculty Member; Department of Archeology and History of Art; College of Social Sciences and Humanities; 258781
Central Greece during the Byzantine era has often been summarily and perhaps simplistically considered by earlier historians as a primarily agrarian backwater, coming to forefront only. Chalcis gradually came under Venetian rule, and served as an international maritime colony. These divergent political conditions also gradually influenced the civic conditions and the urban fabric of both cities. Between the ninth and the twelfth centuries, the “special bond” between two cities was achieved through a matrix of economic, social, and political features, which can be traced down to the level of urban neighbourhoods. In both cities, similar patterns emerge on the basis of material culture and the concentration of activities. The establishment and continuous use of Byzantine neighbourhoods despite the deficiencies in our knowledge of their boundaries, organization, and exact size seem to represent a conscious choice on the part of the inhabitants. Defensive walls played a primary role, defining the walled area as primary and that outside the walls as secondary.
