The Impact of Architectural and Urban Patterns on the Behaviour of an Exhibited Angular Size-Illusion

Djordjevic, Djordje
Djukanovic, Gordana
This paper continues a research in which it has been confirmed that the angular size-illusion underpins a contradictory effect related to a seeming size-decrease of focused architectural and urban objects as the observer approaches them. It explores the impact of various architectural and urban patterns on the behavior of an angular size-illusion noticeable during movement. To obtain sustainable conclusions, real locations are selected and simplified. Simplification criteria are defined respecting the preconditions necessary to trigger such an illusion. Also, two groups of parameters are formulated, both as illusion quantifiers and illusion qualifiers (such as descriptors and determinants). By analyzing the illusion quantifier’s conduct, the established valorization criteria allowed the methodological investigation of influences of illusion determinants on the descriptor’s behavior. The outputs-based conclusions are generalized in a form applicable to contemporary architectural and urban practice, making it possible to estimate and control the behavior of the illusion in reality.


Historical contuinity: three modernist masters, their precedents and descendants
Mollazadeh, Aslı; Balamir, Aydan; Department of Architecture (2014)
The aim of this thesis is to uncover the relation between the concept of historical continuity and architectural modernism. Modernism in architecture has often been conceived as a movement that rejects history. The buildings of modernist masters have been seen alien to their environments and the cultural values of the society. Although there have been many studies disproving this widespread opinion, the continuing effects of modernist works on today's architectural environment haven't been fully understood....
Changing role(s) of the profession of architecture: building information modeling in practice
Özkoç, Onur; Gür, Berin Fatma; Department of Architecture (2015)
This research is an inquiry on the roles undertaken by architects in the complex process of designing and realizing buildings. It focuses on the changing AEC context in Turkey and interprets these changes from the scope of Building Information Modeling (BIM), which claims the instrumentalization of a new mode of production of buildings. Reading BIM as a reflection of the increasing demands of AEC context on the architects’ modes of operation, the thesis evaluates how the changing mode of production of build...
Reconceptualizing the architectural precedent: textual models of reading
Beşeli Özkoç, Heves; Gür, Berin Fatma; Department of Architecture (2015)
The aim of this thesis is to reconceptualize the “architectural precedent” in a way to reveal its potentials as an instrument for architectural design and education. The main concern is to use the architectural precedent as a source of knowledge and form generation, but not as a model for functional problem solving. In order to generate new knowledge and form, the precedent should be read textually rather than formally. While formal reading reveals existing knowledge underlying the precedent, textual readin...
Performance improvement of a 3d reconstruction algorithm using single camera images
Kılıç, Varlık; Platin, Bülent Emre; Department of Mechanical Engineering (2005)
In this study, it is aimed to improve a set of image processing techniques used in a previously developed method for reconstructing 3D parameters of a secondary passive target using single camera images. This 3D reconstruction method was developed and implemented on a setup consisting of a digital camera, a computer, and a positioning unit. Some automatic target recognition techniques were also included in the method. The passive secondary target used is a circle with two internal spots. In order to achieve...
Laser sheet visualization for flapping motion in hover
Kurtuluş, Dilek Funda; Farcy, Alain; Alemdaroglu, Nafiz (American Institute of Aeronautics and Astronautics Inc.; 2006-12-01)
The aim of the present study is to understand the aerodynamics phenomena and the vortex topology of the highly unsteady flapping motion. Instead of the use of real insect/bird wing geometries and motions which are highly complex and difficult to imitate by an exact modeling, a simplified model is used to understand the unsteady aerodynamics and vortex formation during the different phase of the flapping motion.
