    Quantitative Analysis of Urban Morphology: Exploring Ethnic Urban Formations and Structure in the City of Izmir
    (Izmir Institute of Technology, 2009) Alper, Sabri; Arkon, Cemal
    Urban design and planning have been mainly involved in forming and structuring our cities. In order to understand this form and structure, various methods and tools of analyses have been developed in urban morphology. Spatial analysis is of basic need within planning and one of the essential tools for anyone who wants to investigate space. Spatial analyses are also useful tools on the way to a deeper understanding of the city itself. The aim of this thesis is to develop a theoretical framework and quantitative methodology for modeling urban form and structure, in order to better understand the complexity inherent in urban environments and to generate and improve relevant knowledge for urban design and planning. Space syntax is a set of techniques for the analysis of spatial configurations of all kinds, especially where spatial configuration seems to be a significant aspect of human affairs, as it is in buildings and cities. Space Syntax is unique as an analysis tool since it allows us to objectively measure the street network configuration. To explore the geometrical features of urban form, a geometric model is utilized and a typological analysis approach will be used for the basic element of the fabric: .the building block., Quantitative measures obtained from these syntactic and geometric approaches, their relationships and interdependencies are analyzed and explored. An integrated set of measures is identified. Case studies in Izmir are selected for testing the methodology to be developed. Methodology development is concentrated on five ethnic districts at the late-Ottoman period. These are also known as the Greek, Jewish, Armenian, European and Turkish quarters of the city. By analyzing the urban form and structure of these districts, a new integrated quantitative methodology for analysis of urban morphology is presented. Keywords: Urban Morphology, Urban Analysis, Space Syntax, Urban Pattern, Izmir

    Evaluating the Impact of Urban Competitive Advantages on Economic Revitalization of Deprived Inner Cities Through a Case Study Held in İstanbul
    (Izmir Institute of Technology, 2008) Yalçıntaş Ağan, Hande; Arkon, Cemal
    This dissertation assesses the impact of Urban Competitive Advantages in deprived inner city areas in Turkey and strength of the potential for marketability of those advantages, for economic revitalization in the case of Turkey. .The Urban Competitive Advantages Approach., compliant with latest discussions on urban economic regeneration, is a strong economy-based approach focusing on the need for recognition of inherent advantages of distressed inner cities and relies on the development of specific marketing mechanisms to promote those advantages in order to stimulate private inward investment. Accepting true contribution of the approach to urban regeneration, the thesis first examines several projects from abroad to determine key indicators in assessing the competitive capacity of a locality and then, makes use of those indicators in a case study in Istanbul in order to illustrate to what extent the present advantages contribute to stimulation of reinvestment in inner cities given the political uncertainties, economic instability, available financial mechanisms together with legislative and institutional capacities in Turkey. Finally, it is observed that resulting remarks on case study analyses support the main hypothesis of the thesis that .national policy directions and current regulatory, organizational and financial framework for urban regeneration in Turkey can only help finding best economic use of distressed inner city spaces when reformulated in the way they market competitive advantages of concerned spaces.. The dissertation concludes by recommending innovations and reviews through policy directions and necessary mechanisms in legislative, organizational and financial issues for Turkey.

    An Analytical Study of the Design Potentials in Kinetic Architecture
    (Izmir Institute of Technology, 2004) Korkmaz, Koray; Arkon, Cemal; Korkmaz, Koray; Arkon, Cemal
    This dissertation is concerned with the potentials of kinetic structures in architecture; what they are, what they can do for us, and how we can go about designing them. Ultimately, it aims at proving the applicability of kinematic methods in the design process of the adaptable space organizations by carrying out a personal design process of a novel kinetic structure. The course of this dissertation explores the ways in which kinematic synthesis methods contribute to the design processes of kinetic structures and adaptable spaces, which we call kinetic architecture.The idea of motion is not new. However, the concept of motion and its practical reflection appear more in end-products because of the dynamic, flexible, and constantly changing activities and developments in building technology. As a result of the rapid change in activities of modern society and developments in building technology, a need of the adaptable space emerged which was the necessary precondition for the rise of the concept of motion in architecture. This conceptual transformation may be dated to the end of the twentieth century. What marks the approach to the design of this new, late twentieth-century conception of space is 'motion', which will now play an increasingly important role both conceptually and in applications of design. Our capability of utilizing kinetics in architecture today can be extended far beyond what has previously been possible. The present dissertation describes kinematic analysis and synthesis methods used so far in mechanical engineering and explores its direct or in-direct applications into the architectural field.Arguing that the potential of kinetics in architecture remains far from fulfilled, it offers concrete direction and method for innovation. Focusing on responsive spatial adaptability and kinetic structures, it develops a foundation for the application of kinetic structures as a means of enhancing the performance of space. The motivation lies in creating adaptable spaces. There is a need for adaptable spaces and a design method for achieving this by building kinetic structures that can physically convert themselves through kinetics to adapt to the ever-changing requirements and conditions. This thesis proposes the use of kinematic methods in the design process of kinetic structures to create adaptable space organizations. In order to show the applicability of kinematic methods in the design process of the adaptable space organizations, a new type of an architectural umbrella covered by flexible material is developed for covering open-air spaces. Graphical synthesis method is used in the design process and the performance of the architectural umbrella is analyzed with Visual Nastran 4D. This is a CAD program capable of kinematic analysis.

    A Critial Evaluation on the Concept of Justice in Planning Process-Judicial Oversight: the Balçova and Narlıdere Cases
    (Izmir Institute of Technology, 2005) Şenol, Pervin; Arkon, Cemal
    This thesis aims at scrutinizing what is meant by the concept of justice and the ways the concept is being referred to in urban planning practice in Turkey. Aimed as such, the due analysis involves examination of how the concept is taken into consideration and defined by different actors taking part in urban planning process of our country. The basic data underlying the considerations based on not only the conceptual discussions, but also the planning practice will comprise different demands concerning the urban space and the cases of lawsuit under control of adjudication as reflections of these demands upon the process of planning. The questions to which this study based on .justice. in the urban system and the planning discipline are to be answered can be listed as follows: Which concepts, which ideals, which discourses and methods are used during the process of distribution mechanism in the economic realm, law system and judicial process? How are the basic concepts of justice, namely equality, interest, right and liberty used in defining and encountering the urban social needs in these processes? Do the achieved results involve any targeted ends that can be called as just? In order to elucidate the understanding and demands of justice, conceptual information pertaining to the concept of justice is required. For this reason, study focuses on theories of justice and elaborates the fundamental points of concepts, theories and their reflection on the state regulations. Regarding an assessment of the Turkish practice, overall assessments are held as based on cases of lawsuit under control of adjudication. The cases of lawsuit are assumed to represent matters of conflict/dispute and spatial demands of actors regarding the urban space. Accepted as such, the spatial disputes will be elaborated on basis of the matters of case study area in emphasis.

    A Methodology for Geographical Information Systems Based Participatory Decision Making Approach
    (Izmir Institute of Technology, 2001) Yiğitcanlar, Tan; Arkon, Cemal
    Geographical Information Systems (GIS) to come up with better planning can be utilized. But unless the final decisions contain strategic and participatory decisions and are indeed an improvement upon previous solutions and are in fact turned into actions, using a GIS will just not necessarily increase the cost of the planning activities. In this thesis a new approach, which is called "Geographical Information Systems Based Participatory Decision Making Approach (GISbPDM)" is proposed to overcome current planning problems and also to answer most of the debates about traditional GIS. GISbPDM employs three basic components in its body. Collaborative GIS is the first component of GISbPDM and represents the spatial decision support system and makes new GIS trends available - especially Public Participation GIS - for public, urban planners and decision makers. Strategic Choice Approach is the second component of GISbPDM and it is a sophisticated technique for making decisions and developing action plans in situations with many options and uncertainties in a participatory manner.Computer Supported Collaborative Work System (CSCW) is the third component of GISbPDM and has an involving structure - by cooperative work and participatory design supported by computers - for utilization of the collaborative and participatory decision models. The system architecture of GISbPDM has quite a simple mechanism. GIS including the local and central databases is used for data manipulation, visualization, queries and interactive sketching on an easily accessible platform. Strategic Choice Approach is the policy and decision-making model that works interconnected to this GIS platform.Accordingly participants can visualize the alternatives, submit them to the decisionmakers and other participants, allow them to modify the alternatives and create their own proposals. The participation can be realized in different levels such as information participation, collaborative work, public participation and elite participation. Proposed system architecture has an encouraging power for participatory planning and besides CSCW helps in increasing participation in all levels.
