Safe Distributed Control of Wireless Power Transfer Networks
No full textWireless power transfer networks (WPTNs) are composed of dedicated energy transmitters (ETs) that charge energy receivers (ERs) via radio frequency waves. A safe-charging WPTN should keep electromagnetic radiation below predetermined limits meanwhile maximizing the transmitted power. In this paper, we consider this requirement as an optimization problem: the maximization of harvested power by ERs subject to the electro-magnetic safety constraints. In order to provide an approximated solution to this problem, we introduce a dual ascent-like distributed charging algorithm that enables ETs to work without global information and satisfy safety constraints asymptotically. We provide an in-depth theoretical analysis of our algorithm which is supported by numerical simulations.Accepted author manuscriptEmbedded System
Three methods in relation to rate : Described facts in "Sanpou-Tenseihou-Sinan"
No full textLet B, A and p be the base quantity, the quantity of be compared and the rate (or proportion), respectively. There are three methods in relation to A, B and p, that is,
・The first method : p = A/B,
・The second method : A = B×p,
・The third method : B = A/p.
These three methods are technical terms for teaching. We found description of the three methods in wasan's book : "Sanpou-Tenseihou-Sinan" which was published in the Edo period (1810; Bunka 7). The author of this book is AIDA Yasuaki, who is one of famous mathematicians "wasan-ka". We show the described facts in "Sanpou-Tenseihou-Sinan"
Simulation based optimization for world line card production system
No full textApak, Sinan (Arel Author), Ercan, Sami (Arel Author)Simulation based decision support system is one of the most commonly used tools to examine complex production systems. The simulation approach provides process modules which can be adjusted with certain parameters by using data relatively easily obtainable in production process. World Line Card production system simulation is developed to evaluate the optimality of existing production line via using discrete event simulation model with variety of alternative proposals. The current production system is analysed by a simulation model emphasizing the bottlenecks and the poorly utilized production line. Our analysis identified some improvements and efficient solutions for the existing system
"Henry Rider Haggard’s Posthumanist Eco-consciousness"
No full textIn this essay I argue that the late Victorian and early Edwardian novelist Henry Rider Haggard had a distinct eco-consciousness that was reminiscent of twenty-first century posthumanist philosophies as early as the 1880’s. Writing his “imperial romances” in the wake of the beginnings of what is now called the Anthropocene age, Haggard observed and understood the changing relationships between the human society and the more-than-human world in this historical period. In a manner that would be unexpected of an author widely labeled as ‘a man of his times’—and therefore a pro-imperial propagandist—in postcolonial literary criticism, he was critical of the anthropocentric ways of western civilization. Ranging from a Darwinian notion of the oneness of all living animals to a highly skeptical attitude toward the reckless exploitation of the resources of colonial lands and peoples, Haggard’s Weltanschauung included notions that were not only antithetical to imperialist discourses, but also ‘ahead of [their] times’ by more than a century. In this essay I elaborate on Haggard’s posthumanist eco-consciousness with reference to his fiction and conclude that a renewed understanding of Haggard’s literary and intellectual heritage would show how his works are still very much relevant and valuable in our time
Dilemma Between Density and Quality: The demographic history of Sinan Road area
No full textThis paper investigates the unique urban planning history and demographic changes in Sinan Road (also named as Rue Massenet) Area of Shanghai and the socioeconomic impacts on local inhabitants’ living quality led by formal and informal planning dynamics. Examining both tangible and intangible characteristics of this area under five different historical phases, this paper indicates that population density and urban quality cannot always be positively or negatively related. Urban quality can reach the maximum value when area population of concentrated density stays in an ideal state, although, as a result of the qualitative variates, such state (peak value) is in suspense. Through analysing the overarching strategic plan of different periods, it also argues that urban quality is not merely dominated by or directly related to density but more by the population’s social demands and their initial interaction with a specific area, active or passive involvement.History, Form & Aesthetic
Super Sinan

Meanwhile devoted, on a wider level, to reducing the functionality and metaphorical forms of architecture, to an architecture reduced to its barest form – a "typical plan" aimed only at staging the production of everyday life through the most basic architectural practice that has been testified by the "Elementi Primari" of Istanbul. Upon dramatic different scales, it created a various hierarchy space within which where all activities are housed by one simple, consistent architectural gesture. A gesture that stems from the primary elements in the city, faded through time, albeit more pervasive in actuality. "Enciclopedico"Public buildingarchitectureArchitecture and The Built Environmen
Monodromy of torus fiber bundles and decomposability problem
No full textThe notion of a (stably) decomposable fiber bundle is introduced. In low dimensions, for torus fiber bundles over a circle the notion translates into a property of elements of the special linear group of integral matrices. We give a complete characterization of the stably decomposable torus fiber bundle of fiber-dimension less than 4 over the circle. (C) 2017 Elsevier B.V.

Geology, mineralogy and the Pb, S isotope study of the Kalkim Pb-Zn +/- Cu deposits, Biga Peninsula, NW Turkey
No full textWOS: 000329991100004Three main Pb-Zn +/- Cu deposits (Handeresi, Bagirkacdere, and Firincikdere) occur south of Kalkim in the southeastern part of the Biga Peninsula (NW Turkey). Massive and disseminated Pb-Zn mineralization consists of ore veins in fault zones and replacement bodies in carbonate layers in metamorphic rocks. Garnet (similar to Ad(64)Gr(36)), pyroxene (similar to Di(30)Hd(45)Jo(25)), epidote and rare tremolite-actinolite are found as gangue minerals in ore zones. The garnets often show oscillatory zoning and correspond to grossular, andradite and grandite in composition. The pyroxene minerals are manganiferous hedenbergite, johannsenite and diopside. The Mn/Fe ratios of the pyroxene range between 0.3 and 0.9 (mean 0.5). Such compositions of the garnet and pyroxene and gangue assemblages are typical of distal Pb-Zn skarns. The ore minerals are pyrite, sphalerite, chalcopyrite, galena, magnetite, hematite, and arsenopyrite. The mean lead isotopic values for galena are Pb-206/Pb-204 similar to 18.760, Pb-207/Pb-204 similar to 15.689, and Pb-208/Pb-204 similar to 38.935. The comparison of these isotope data with the host-rock samples (graphite schist, andesite and granodiorite) indicates that part of lead could have been leached from the schists. The delta S-34(VCDT) values for galena, sphalerite, and chalcopyrite are -1.1 to + 1.5 % (mean: -0.2 %), 0.7 to + 2.1 % (mean: + 0.7 %), and -0.6 to + 1.5 % (mean: + 0.4 %), respectively. Lead isotope data and delta S-34(VCDT) values close to 0 % indicate the formation of ores by magmatic processes. Taken together, the Oligo-Miocene magmatism in the area is taken responsible for the polymetallic mineralization. However, the metamorphic rocks and their protoliths may have contributed part of the lead.Scientific Research Office of Ankara University (BAPRO) [06B4343007]This study is a part of the Ph.D. thesis of the first author at the Geological Department of Ankara University supervised by third author and also was supported by Scientific Research Office of Ankara University (BAPRO), Project No. 06B4343007.
