Acoustic design based on multi-aspect performance analysis
(Izmir Institute of Technology, 2013) Atça, Emre; İlal, Mustafa Emre
In current architectural practice, architects, due to time and budget constraints do not analyse their designs and evaluate alternatives from the building physics perspective. They expect this analysis to be carried out by engineers. Unfortunately, engineers mostly get involved late in the design process, after many key decisions are already finalized, leaving them powerless to solve problems employing efficient strategies. However, the rapid advances both in computing and engineering have produced various simulation based tools for evaluating building performance that architects themselves can employ in the early design stages. The proliferation of the utilization of these tools throughout the architectural practice and education is necessary for achieving higher performance levels in the built environment. In this study, the main Lecture Hall at Izmir Institute of Technology, Department of Mathematics is diagnosed and documented through measurements and the possibility of predicting this existing level of performance through simulations during the design stage is explored. The brand new Lecture Hall is in urgent need of renovations, with additional costs, in order to improve acoustic, visual and thermal comfort in the space. Architects need to follow a performance based design approach where they consider performance criteria and utilize building simulation tools for design support in order to avoid problems that introduce costs later in the construction and operation of buildings.
The activity of silica immobilized palladium N-heterocyclic carbene complexes toward Mizoro-Heck reaction and their characterization
(Izmir Institute of Technology, 2005) Aksın, Özge; Artok, Levent
C-C bond formation reactions are among the important processes in chemistry.A palladium-catalyzed reaction, commonly known as the Mizoroki-Heck (M-H) reaction, is a powerful method in construction of C-C coupling of olefins with aryl and vinyl halides.This thesis describes, mainly development and applications of novel silica anchored saturated molecular Pd-N-heterocyclic carbene (Pd-NHC) catalysts toward the M-H reactions of aryl halides.Characterization of the novel Pd-NHC complexes were performed using elemental analysis, NMR and X-ray crystallography techniques. The synthesized complexes were anchored over an amorphous silica surface through their triethoxy silane groups.On the basis of the results, the silica supported saturated Pd-NHCs were found to be highly active catalyst precursors for Mizoroki-Heck reactions of iodo- and bromoarenes with styrene and butyl acrylate olefins, when reactions were performed at 140 C in the presence of 1.5 molar equivalent Na2CO3 base. The catalyst preserved its original activity for 4-iodoanisole, 4-bromoacetophenone, 4-iodoacetophenone, iodobenzene and 4-iodotoluene reagents at least for 8 uses when Pd concentration, with respect to the aryl halide, was 0.5% in the reaction medium.The higher turnover frequencies were realized at the lower Pd concentrations. The AAS analyses revealed the presence of dissolved Pd species within the reaction medium at the early stages of reaction. Along with this finding, determination of Pd agglomerates onto silica surface by TEM examination indicates that the catalyst acted as a Pd reservoir and reactions were catalyzed homogeneously. In the course of reaction, Pd is liberalized to the solution involved with the reaction cycle and deposited onto silica surface to lead to form less active Pd agglomerates. That no trace of dissolved Pd was detected at the end of reaction by AAS is a positive finding for the purity of product.
Analysis of building information modeling (BIM) performance using big data from a construction project
(01. Izmir Institute of Technology, 2023-07) Bostan, Berkay Batuhan; Çavka, Hasan Burak
This study aims to propose a systematical approach for evaluating BIM performance from a main contractor's perspective based on big data from a construction project. Retrospective case study is used as the research approach. Data is collected through interviews with the main contractor firm, and data from the logged project information in project databases including ACONEX and Microsoft Excel files. A framework containing performance metrics, specifically tailored to evaluate BIM performance based on big data, is developed from the combined analysis of literature review, interviews with main contractor, and overview of the project data. Collected project data and interview data are analyzed using the developed framework. Results of the data analysis are verified through follow-up interviews with the main contractor firm. Findings of the study suggest that it is possible to evaluate the BIM performance through analysis of collected BIM big data using the proposed systematical approach. Several performance problems were identified during the data analysis. Follow-up interviews revealed that identified performance problems from the data analysis largely coincided with the real-life experiences and accurate data entry is the key criterion for the analysis to yield correct results. The proposed framework should be tested in wider range of studies and may serve as a foundation for a future benchmarking system. Future work should focus on refining performance metrics, establishing a BIM big data database for benchmarking, exploring data's potential to be used for real-time performance assessment, and implementation of emerging Artificial Intelligence (AI) techniques for the analysis of big data.
Analysis of four urban squares in Izmir according to the leading urban design literature
(Izmir Institute of Technology, 2018-12) Ceyhan Abacı, Fatma; Çil, Ela; Velibeyoğlu, Koray
The squares are the significant elements of the urban public spaces that provide the users different experience in the city, activate their city life and they are human oriented places for cities and societies. The squares are strong accumulation places where each day a different experience comes true so they transfer society‟s culture, social habits, way of life, memories from past to the future. Since urban squares have those significant roles for cities, researching the spatial, functional and social qualities of the squares are very important to understand and identify them. The aim of this study is to reveal the characteristics of urban squares according to leading literature studies. The study focuses on what are the criteria we need to analyze in order to determining the qualities of the squares. Accordingly, the main common ideas on urban squares in the literature have been categorized to evaluate the squares. The leading qualities of the squares comprise of the ten normative criteria based on sixteen important authors of related studies which are the main textbooks of the thesis. The content of the criteria consists mainly of the characteristics that the square must have physically, socially and functionally. In this study, Ali Paşa Square, Hatuniye Square, Cumhuriyet Square, and Gündoğdu Square are chosen in İzmir as case study area. The study cases are observed and analyzed according to ten evaluation criteria. The analyses results extract the characteristics of each square. All findings, results and normative criteria are together discussed as results. The results of this study may guide to reconsideration of urban squares within modern usages and designing more useful squares for further studies.

An analysis of the impact of the exchange rate pass-through (ERPT) to construction cost index and housing unit prices in Turkey
(01. Izmir Institute of Technology, 2021-07) Lağap, Umut; Kale, Serdar
After the high-speed globalization attack, the interrelations between countries have increased significantly, and local economies have become vulnerable to global economic developments. Despite the successful monetary policies in the 2000s, the Turkish Lira has severely depreciated against foreign currencies in the last decade. Thus, the exchange rate pass-through (ERPT) to domestic prices and its relationship with other macroeconomic variables has become a hot topic for governments and scholars in the literature. However, this pass-through effect on the Turkish Construction Industry and the Housing Market is minimal, although they play a pivotal role in the Turkish economy. With Vector Autoregression (VAR) models analyzing the collected monthly data between 2010 and 2020, this study reveals (1) the ERPT to housing unit prices in Turkey (hup1) and Istanbul (hup2), (2) the change in this pass-through effect during economic stabilization, and fluctuation in the Turkish economy. Moreover, this thesis uncovers (3) the ERPT to Construction Cost Index (cci1) and its material component (cci2) between 2015 and 2020. As a result of Variance Decomposition (VD) and Impulse Response Function (IRF), the housing mortgage rate's (hmr) effect on hup2 is much more significant than its effect on hup1 in the first two years. However, there is no significant difference between the nominal exchange rate's (exr) effects on these prices in the same period. Besides, the effects of hmr and exr diminished during economic stabilization. Moreover, the ERPT to cci1 is greater than the ERPT to cci2 at the end of the first year.
An analysis on the aqua-architecture and its internal dynamics
(Izmir Institute of Technology, 2000) Ay, Nevin; Eyüce, Ahmet
Water has always been an undeniable element of the settlement, nature and continuity. At the beginning water has seen as a need for living organisms, (i.e. drinking, heating, worshipping, washing, etc.) later on with the urbanization the importance and necessity of the water has increased and has started to carry more social meanings. In the course of time, people wanted to use all the gadgets and functions to make their lives much more comfortable. Human settlements next to the water resources are a basic example for the importance of water in our lives. The connection between water and people has shown varieties from society to society and culture to culture. But it has always got the priority in our lives. Even different professions saw the water in a different perspective and used in their occupations. The designers and architects who are not denying all those different point of views have been taken water as an element into the world of design.In architectural designs sometimes water can be used as a design tool and sometimes as one of the components, which constructs the concept. Also water has the potential to effect its environment. So those features have made water an important element in design.The concern of this thesis is about; How the alterations in water utilization is effecting the architecture discipline and; How can water element be used in the course of periods and cultures? In this study the internal dynamics of water element have been introduced and those internal dynamics have been discussed and categorized. At the mean time proposed conclusions of this study are that the importance of water element in architecture should be underlined and increased. And water element should take its place in the architectural design literature more actively.
An analytical approach to the concept of 'Topography' in architecture
(Izmir Institute of Technology, 2003) Muyan, Cem; Eyüce, Özen
The symbiosis of man and nature reveals their diverging interrelations, which are based on man's shifting idea of nature throughout history. These alterations in man's conception of nature have changed his attitudes towards it, thus his creations in relation with topography. Hence, within the scope of the study, the idea of nature, exploring its shifted meanings, is analyzed in order to contemplate the relationship between manmade and natural environment. Being guided by the urge to anchor to the world, man has always been in search of establishing somehow ideal relationship between manmade and natural environment within which topography remains as the most prominent concept in the context of physical surrounding. Therefore, the concept of topography is handled as the main concern of the thesis. By means of treating topographical formations whether as sacred places or as physical aspect of the world with which to create intimate relationship or as mere subordinate elements, man testifies that topography has had differing impression on his mind in accord with his idea of nature.In today's world where everything may be questioned about its authenticity or its state of being natural, the concept of topography in contemporary architecture, which has also an artificial sense and very different understanding than its precedent conception, is aimed to be explored while revealing its roots.Consequently, in the context of the study, besides the investigation of the changes in the conception of nature and its reflections on manmade environment, the concept of topography is examined in order to disclose the changes in its meaning that direct the way man deals with it. The consequences are aimed to be justified through an analytical method.Keywords: nature, topography, ground, folding, continuity.
Analyzing the communication and coordination processes in Sabiha Gökçen International Airport's new terminal building wayfinding project
(Izmir Institute of Technology, 2011) Erbaşaranoğlu, Bengi; Doğan, Sevgi Zeynep
Coordination is the third main function following design and construction in the building process. It is a sensitive managerial activity involving well-defined procedures and smooth flow of communication in all directions to achieve project objectives. This study builds on existing coordination theory and utilizes the four key coordination processes defined by Malone and Crowston (1994): (1) Managing shared resources (2) Managing producer-consumer relationship (3) Managing simultaneity constraints (4) Managing task/subtask dependencies. Four processes were interpreted and operationalized for the study of the e-mail data obtained from the wayfinding project coordination of new terminal building of Sabiha Gökçen International Airport. The organizational schema of the wayfinding project defined the e-mail communication analysis to be among the contractors, consultant and the design firm. Social network analysis is conducted for network centrality measures. Degree, betweenness and closeness centrality values are calculated for each project participant. There are three major findings from these analyses. First finding suggests that centrally positioned Wayfinding and Signage Design Project Contractor in the organization schema shows more coordination. Second finding suggests that task/subtask dependencies, producer-consumer relationship, simultaneity constraints and shared resources need respectively more coordination effort to manage in a wayfinding project. Third finding shows e-mail communication has a profound effect on coordination. The implications of these findings mean that companies involved in design and construction process may consider providing new approaches affecting dayto-to-day interactions depending on the power of new technological coordination mechanism.
Annexes and extensions in historical buildings: An ideological perspective
(Izmir Institute of Technology, 2002) İlter, Buket; Çıkış, Şeniz
The art of designing additions carries with it a host of unique challenges. Especially, in the case of annexes and extensions in historical buildings, ideology can be an important factor in shaping the design of the addition. Ideology.s close relation with the concept of identity also makes it a factor in shaping additions in historic buildings. However, studies about the subject generally address themselves to the examination of the functional necessities, and aesthetic concerns. Additions in historic buildings are mostly evaluated within the scope of conservation, and with their harmony to the historical context. This study attempts to analyse the design of additions in historical buildings from a different perspective, leaving aside the principles conservation and discussions of contextualism. The aim of the thesis is to analyse the reflections of ideological and social changes in the physical environment, and to examine the additions in historic buildings from that point of view. Within the scope of this thesis additions in historical buildings are investigated with special emphasis given to the concept of ideology. The interaction between ideology and architecture is explained through an examination of international and local samples. Also, the concept of conservation and historic building is discussed in relation to ideology. Basic reasons for building new architecture in historic settings are examined. Finally, classifications of addition buildings according to their location design approaches, and combined expressions are made.
Architectural periodicals as a reflective medium of the agenda: A study on Turkish architectural media during the republican period
(Izmir Institute of Technology, 1999) Özdel, İlker; Eyüce, Ahmet
This study claims that architectural periodicals, which reflect architectural production of their period, also serve as independent mediums of activity and production within the discipline of architecture. In this respect, the study proposes that architectural periodicals can be used as means to evaluate the architectural present and aims to examine the architectural process of Republican Turkey with respect to the transformations and interruptions that can be observed in the simultaneous architectural periodicals. Within the scope of the study, in order to verify the two-way relationship between the architectural periodicals and the architectural agenda; periodical publications have primarily been evaluated as a form of media, with a focus on the transmitting, interpretive, critical and trans formative approaches of the periodical publications in the field of design and architecture. This conceptual framework has been used to investigate the reflections of transformations in the political, cultural, economical and social dynamics on architecture and architectural publishing. As a result of this evaluation, the study presents an interpretation of the contemporary architectural milieu in Turkey with a critical approach based on architectural periodicals.This academic work should also be considered as an initiative effort for the documentation of the sixty years of Turkish architectural publishing.Keywords: media, periodical publications, architectural periodicals, architectural theory, architectural praXIS, architectural criticism, Republican Period, Turkish Architecture, 1980.
Architectural reflections of the political thresholds during interwar years (1914-1945)
(Izmir Institute of Technology, 1999) Emir, Özgür Deniz; Eyüce, Özen
This thesis claims that political power and ideology have the ability to transform the building forms of architecture and that power uses architecture as the ideological symbols of the regime in the interactive relationship of 'Architecture and Politics'. The study examines this relationship in Russia, Germany, Italy and Turkey which are experiencing political thresholds during the' Interwar Years' (1914-1945). The architectural reflections of political thresholds have been discussed through architectural trends, styles, built environment and urbanism. Formal and conceptual analyses and readings have been performed in order to determine the architectural transformations and variations that are parallel to political developments, architectural trends before and after the political thresholds have been analyzed comparatively. The concepts that exist similarly both in political ideologies and architectural end-products have been studied with the aim of finding the interaction between 'Architecture and Politics'. These analyses have led to a conclusion that political interference, transforms architectural trends due to its ideologies; monumentality, grandeur, axiality, symmetry order and hierarchy as a result exist in the created architectural language due to this political interference.
Architecture student's perceptions of design and its transformations throughout their education
(Izmir Institute of Technology, 2013) Taneri, Batuhan; Doğan, Fehmi
This study explores how students of architecture characterize design. It focuses on the transformation of student's conception of design as they move from first year to fourth year in their undergraduate education. The study employs surveys and in-depth interviews with selected groups of students from all four levels among the students of architecture in Izmir Institute of Technology and Dokuz Eylül University. It was found that characterization of design as problem solving is the dominant preference among the students of architecture because design studio pedagogy imposes a conception of a more linear design process which corresponds to design as problem solving. Nevertheless, the students are aware that design process is not as linear as it is taught in the studio. It can be said that the strategic approaches the students developed are caused by this contradiction between the nature of design process and the current applied pedagogy.
Architecture, community and the Aga Khan Award for Architecture
(01. Izmir Institute of Technology, 2021-07) Keser, Elif; Erten, Erdem; Yücel, Şebnem
This thesis aims to understand/explore how architecture can assume social responsibility and offer solutions to social problems by focusing on projects awarded by the Aga Khan Award for Architecture (AKAA). Unlike many major architecture awards, the AKAA prioritizes social contribution and the projects selected by the award features architects taking social roles other than simply being the designer. While examining the social responsibility of architecture, the thesis explains the alternative roles that the architect can take on regarding certain themes. The first chapter investigates the history of "community-oriented architecture" and its examples in the literature. The second chapter focuses on the projects awarded by the AKAA with reference to the contributions of architecture to social development. From the first award period to the last (1980-2019), 124 projects were examined and 8 examples suitable to the scope of the thesis were selected. When selecting these examples, three main themes were determined (using parameters such as economic resources, relations with local government, organization, community education, etc.): "Participatory Architecture", "Urban Upgrading and Community Development", "Historical Restoration and Socio-Economic Revival". Under these themes, subheadings were created according to the alternative social role assumed by the architect. The extensive archive of the Aga Khan Award for Architecture was used for the necessary documents such as detailed information about the projects, technical reports, jury reports.
Assessing the service quality of intelligent building control systems: An importance-performance analysis
(Izmir Institute of Technology, 2015-07) Kahraman, Nil; Doğan, Sevgi Zeynep
Recently, control systems are being integrated to an increasing number of buildings, which are then labeled as “intelligent”. Even though the intelligence label creates a considerable market share, intelligence-indicator building control systems are under-researched in terms of the expectations of customers. This thesis analyzes customer satisfaction for intelligent building control systems by assessing expected and perceived service levels that reveals service quality. In order to achieve this, two web-based surveys inquiring both the importance and the performance levels of control systems were conducted. The collected data were then analyzed by a customer gap analysis depending on an importance-performance analysis. Among the seven control systems investigated, building automation system is found to be the most important intelligent control system integrated to a building. Yet, it is also found to be one of the underperforming control systems investigated. Thus, the largest customer gap indicating the lowest service quality is defined for building automation system towards which managerial effort and concentration should be directed urgently for proper improvement purposes. Heating, ventilating and air conditioning system shows the second largest customer gap that constitutes the second highest priority. Although, vertical transportation system is found to be one of the most under-performing control systems, since it is also found to be the least important intelligent control system, it has the lowest customer gap, which indicates low-priority. The findings of the thesis could be of help to develop effective strategies for the management policies of construction and building automation companies.
Assessment of inside ears (CIC) hearing aids device, major ıssues and solutions
(Izmir Institute of Technology, 2019-10) Kraiem, Mejdi; Başoğlu, Ahmet Nuri
Hearing aids come from the widest medical sector that involves many other sectors that they work in collaborations with. A hearing aid demand work in many aspects starting from auditory, psychologic ergonomic and technologic etc. pushing forward the product to reply user’s personal needs. Through the evolution of the hearing aids, the design tends to be miniaturized in response to the psychology or the comfort side of patients and the market respond positively. Minimizing items would be great in several respects but would also higher risk to be lost. As long as the hearing aid’s industries looking forward to improving and idealizing the product there will be a long journey in the future to match technologies and innovative design to come over those issues, there will be a lot to criticize and work on. This study started with a literature survey in order to construct a clear idea about the item and their impact on the user with or without it and collect any potential technologies for better user experience. Later qualitative studies, an interview in depth and satisfaction survey, in which Interview in depth was done with some audiometrist collecting their preview from their patients. The Interviews where recorded. Then comes the satisfaction survey destinated to the users of hearing aids. In the satisfaction survey, we took into consideration if the user has tried both behind the ear and completely inside the ear to see if there is any remarkable preference or rejection between both items. To sum up, this study case is to collect any failure or issues that might face the hearing aids users in aim to put the light on some potential solution to enhance the experience of the users. So do to marketing demand to the miniature of hearing aids caused by the stigmatization of users, factors and facts like battery life, technologies, invisibility or secrecy of hearing aids and fear of losing it should be considered to enhance and improve the experience of hearing aids users.

(Izmir Institute of Technology, 2006) Pekdur, Ömer; Keçeci, Emin Faruk
This study presents the design of a municipal solid waste separation facility that uses physical properties to separate solid wastes into their types. This facility will be autonomous and automatic. There will not be any human personnel nor any sensors to separate solid waste in this facility. Only physical properties like size and density are used to remove materials so this facility will be more robust and efficient than current facilities. All recyclable materials will be taken from a waste stream that contains minimal useless waste. The capacity of the facility will be calculated and the facility will be designed for the city of zmir. The design of a municipal solid waste separation facility includes examining and recent separation facilities in the world and in zmir, seeing problems at their source in zmir and taking suitable separation machines with suitable capacity by examining systems to make a process flow chart.
Between deconstructivist architecture and hyper-historicism: Daniel Libeskind and Turkish architects
(Izmir Institute of Technology, 2008) Maden, Feray; Şengel, Deniz
Having its origins in the discipline of philosophy and the work of Jacques Derrida and emerging from the architectural concerns of the late twentieth century, deconstructivism has profoundly affected architectural theory and practice. In contrast with extant analyses of deconstructivist architecture in formalistic and stylistic terms, this thesis undertakes in Part I in three chapters a survey of the pre-history of deconstruction starting with the early twentieth-century avant-garde movements, and modernism and postmodernism, demonstrating debt and difference, and describes in detail the paths by which deconstructive philosophy was assimilated into architecture, including an extensive reading of Derridean concepts and their implementation in architectural discourse.In two chapters, Part II undertakes demonstration of how and why Libeskind.s architectural design derives from a deconstructivist position and proves his difference from architects like Eisenman, Hadid, Tschumi, Koolhaas, Himmelb(l)au, and Gehry who have been classified as deconstructivist. The thesis identifies Libeskind as the paradigmatic deconstructivist architect by criteria obtained through close reading of Three Lessons, Micromegas, Chamberworks, and the Jewish Museum Berlin. He is shown to differ from his contemporaries by a design approach that attaches fundamental importance to .memory. and .history. as well as a systematically developed alternative to conventional architectural drawing.Part III, in two chapters, offers an overview of Turkish architectural history in the twentieth century in order to identify some contemporary Turkish architects as test cases for descriptive classification as deconstructivist and undertakes analysis of five architects with reference to criteria established in the Libeskindean context.
BIM execution process of construction companies for building projects
(İzmir Institute of Technology, 2016-06) Gerçek, Bilge; İlal, Mustafa Emre; Günaydın, Hüsnü Murat; Tokdemir, Onur Behzat
Building Information Modeling (BIM) is an emerging concept in architecture, engineering and construction (AEC) industry promising to replace traditional 2D based construction documentation and management procedures and to reduce rework and cost in project execution. The level of information that could be assigned to building objects in BIM technologies could provide vast amounts of benefits to construction projects throughout projects’ life-cycle. Implementation of BIM, however, requires strategic planning to enable achieving these potential benefits. Industry-wide and organizational implementation guidelines and standards have been published around the world either to encourage organizations to adopt BIM or to present the minimum requirements to be followed where BIM implementation is a statutory obligation. In contrast, BIM implementation and/or deliverables has not been mandated by government or organizations yet in Turkey, therefore organizations which plan to adopt BIM processes have to develop their own implementation plans. The purpose of this study is to provide guidance in BIM implementation for construction companies particularly during the construction phase of the building projects. BIM standards and guidelines, and studies related to BIM implementation have been reviewed and important aspects of implementation have been identified. A case study of BIM implementation at a large construction company in Turkey to conduct quantity takeoff and cost estimation are presented and unique challenges of BIM implementation in Turkish AEC industry are discussed.

(Izmir Institute of Technology, 2014-07) Yücel, Ufuk; Savaci, Ferit Acar
In this thesis, the memory systems of the brain are researched and the relationship between these memory systems and memristor theory are studied. Firstly, the ideal memristor theory is studied. By using the cubic memristor that was based on the ideal memristor theory, the basic logical operations are explained. Additionally, the nerve cells and synapses, which are thought where the memory and learning take place, are inquired. Bearing in mind that the characteristic of the memristor and its similarities between the synapses has been researched with the previous studies on this field. Finally, memristor data storage system has been designed by using memristors, and a binary image of 12x60 pixels has been successfully stored on this design. Also, the edge detection for images has been presented by using the memristor cellular automaton and some examples have also been given.
