The time evolution of Earth with her cities, languages and countries is considered in terms of the multiplicative noise(1) and the fragmentation processes, where the related families, size distributions, lifetimes, bilinguals, etc. are studied. Earlier we treated the cities and the languages differently (and as connected; languages split since cities split, etc.). Hence, two distributions are obtained in the same computation at the same time. The same approach is followed here and Pareto-Zipf law for the distribution of the cities, log-normal for the languages, decreasing exponential for the city families (countries) in the rank order over population, and power law -2 for the language families over the number of languages in rank order are obtained theoretically in this combination for the first time (up to our knowledge) in the literature; all of which are in good agreement with the present empirical data.

Physics of randomness and regularities for cities, languages, and their lifetimes and family trees Tuncay, C. (World Scientific Pub Co Pte Lt, 2007-10-01) Time evolution of the cities and languages is considered in terms of multiplicative noise(1) and fragmentation(2) processes; where power law (Pareto-Zipf law)(3) and slightly asymmetric log-normal (Gauss)4 distribution result for the size distribution of the cities and for that of the languages, respectively. The cities and the languages are treated differently (and as connected; for example, the languages split in terms of splitting the cities, etc.) and thus two distributions are obtained in the same comp...
Construction of central knowledge of family: family structure analysis in Turkey through state surveys 1968, 1988, 2006, 2011 Turğut, Mustafa; Beşpınar Akgüner, Fatma Umut; Department of Sociology (2016) This dissertation analyzes how centralized knowledge about the family has been structured by the state through stitching it between time and space on the topos of society. States’ socio-political intentions related to the institution of family have been also embedded in scientific investigation process. In this realm, I argue that statistics and structural functionalist theoretical framework have been intensively used in the state funded surveys. In order to elucidate the role of the state in respect to for...
Automated biological data acquisition and integration using machine learning techniques Çarkacıoğlu, Levent; Atalay, Mehmet Volkan; Department of Computer Engineering (2009) Since the initial genome sequencing projects along with the recent advances on technology, molecular biology and large scale transcriptome analysis result in data accumulation at a large scale. These data have been provided in different platforms and come from different laboratories therefore, there is a need for compilation and comprehensive analysis. In this thesis, we addressed the automatization of biological data acquisition and integration from these non-uniform data using machine learning techniques....
MAPPING IN URBANISM: THE ROLE OF MAPS AND MAPPING IN URBAN DESIGN THINKING Tufan, Aybüke; Çalışkan, Olgu; Urban Design in City and Regional Planning Department (2022-8-31) Maps have been primary representations of space for centuries and the traditional approaches in cartographic production have bounded mapping practices in a rigid, conventional, and scientific framework. Within that framework, the relationship between maps and urbanism was limited to the representative aspects of mapping to read the visible elements of geographies, regions, cities, and built environments. However, with the post-representative, post-structuralist and postmodern theories on maps and mapping, a...
Design promlematique of paired border cities Erkan, Rüya; Çalışkan, Olgu; Zırh, Besim Can; Urban Design in City and Regional Planning Department (2018) International borders are concrete places that contain many dynamics within, expressed in abstract lines or abstract areas on the map. In the past, the concept of the border, which sustained its daily existence, has undergone both spatial and semantic changes. During these changes, the problems of the interface between the human relations, the border-crossings and the structure under the two different systems between the two sides of the boundary have always been fresh and agenda. Moreover, it has always be...
