Master Thesis Assessing the Walkability Principles: the Case Study of Mehmetçik Boulevard(Izmir Institute of Technology, 2019) Bağcı, Seda; Kaya Erol, NursenWalkability is defined as the action of the human being to go from one place to another. The streets are one of the most important parts of the built environment and their using by pedestrians increases urban consciousness and social ties. The quality of walkability varies according to the location, usage, and character of the public space. Walkability issue has become more important due to urban growth and an increase in vehicle usage in today's' cities. Increasing walkability in a city increases livability. The aim of this thesis is to assess the walkability quality of urban streets considering walkability principles. In this context, the thesis aims to investigate the principles that affect walkability in urban centers and considering walkability principles to examine the built environment characteristics and pedestrians' usage of a street through a case study. The thesis also attempts to offer recommendations for creating more walkable spaces. For these purposes, firstly, the definition and importance of the concept of walkability are examined. Secondly, walkability principles of the streets in urban centers are established. Thirdly, Mehmetçik Boulevard, which is located in one of the sub-centers of İzmir and used intensively during the day, is evaluated according to the walkability principles. In this study, the walkability quality of the boulevard is examined and assessed in the context of diversity, accessibility, safety, street quality, comfort and legibility principles. Finally, as a result of the literature study and the case study, recommendations are provided to increase walkability quality of Mehmetçik Boulevard, and as well as for urban streets of other cities.Master Thesis Assessment of Wood Laminated Material for Housing Production(Izmir Institute of Technology, 2019) Balkan, Selçuk; İnceköse, ÜlküToday, laminated wood material is used in different types of structures. In many countries such as our country, as well as countries where this usage is intense, laminated wood material is not preferred in housing production yet. Although it seems that reinforced concrete structures have replaced wooden structures today, environmentally sensitive approaches expressed with concepts such as sustainability, ecological balance and repeatability have enabled the reuse of wood material. In this study, the properties of laminated wood technology, which is predicted to be an alternative technology to conventional construction technologies, are evaluated. With this assessment, laminated wood technology could be an alternative structure production technology in our country. At the beginning of the study, wood materials, wood damaging factors, composite wood materials, the use of wood in residential production and the use of laminated wood in residential production were examined under four main headings. The properties of wood materials and laminated wood materials were examined in detail and the methods, advantages and disadvantages of these materials were determined. This study is detailed on the structure of JZ House which was designed and built by architect Serhat AKBAY in Antalya with laminated wood technology. The laminated wooden parts produced for the building were examined based on scientific data on the design process, static resistance of the building, fire resistance, sustainability, environmental and human health contributions. With the evaluation, it is aimed to increase the preference of wooden structures constructed with developing wood technology.Master Thesis Estimation of Low Sucrose Concentrations and Classification of Bacteria Concentrations With Machine Learning on Spectroscopic Data(Izmir Institute of Technology, 2019) Mezgil, Bahadır; Baştanlar, Yalın; Baştanlar, YalınSpectroscopy can be used to identify elements. In a similar way, there are recent studies that use optical spectroscopy to measure the material concentrations in chemical solutions. In this study, we employ machine learning techniques on collected ultraviolet-visible spectra to estimate the level of sucrose concentrations in solutions and to classify bacteria concentrations. Some metal nanoparticles are very sensitive to refraction index changes in the environment and this helps to detect small refraction index changes in the solution. In our study, gold nanoparticles are used and we benefited from this property to estimate sucrose concentrations. The samples in different low sucrose concentration solutions are obtained by mixing the sucrose measured with precision scales with pure water and then the UV-Vis spectrum of each sample is measured. For the bacteria concentration solutions, spectra for six different bacteria concentrations are captured. Spectra of the same solutions are also captured before adding the bacteria. For each of these solutions, four sets are prepared where gold nanoparticles are not grown (minute 0) and grown for 4 minutes, 10 minutes and 12 minutes. After the dataset preparation, these spectrum measurements are transferred into MATLAB environment as sucrose concentration dataset and bacteria solution dataset. Then the necessary preprocessing steps are performed in order to get the most informative and distinguishing information from these datasets. The raw measurement values and processed spectrum measurements are trained with shallow Artificial Neural Networks (ANN) on MATLAB Deep Learning Toolbox and Support Vector Machine (SVM) on MATLAB Statistics and Machine Learning Toolbox. When the results of the conducted machine learning experiments are examined, success rate is promising for the estimation of sucrose concentrations and very high for classification of bacteria concentrations in pure water solution.Master Thesis Plant-On Devices for Sed Screening(Izmir Institute of Technology, 2019) Yetgin, Ali; Pesen Okvur, Devrim; Canlı, KeremThanks to their roots, plants take the required molecules from the soil, therefore their research is important. The fact that absorption takes place from the root hair makes the observations necessary. The inadequacy of traditional methods requires the development of new methods to ensure their observations, especially during root studies. The fact that chip systems have the features that can overcome the problems has caused plant researches by using this method. The fact that environmental factors can be imitated in chip systems paves the way for abiotic stresses to work. Although abiotic stresses have been studied extensively on plants, seed germination and subsequent root extension and root hair formation have not been studied in detail except for the model organism (Arabidopsis thaliana). The use of chip system for plant studies of scientists have begun the 21st century is also reveals the need to do more work in this area. Researchers show that they are excited about the advantages they bring to the system and that necessary studies will be carried out in other side branches. It is thought that more research will be done by using chip systems after a short time. By using chip systems, a suitable environment for seed growth can be provided and environmental conditions can be simulated. By creating the desired controlled environment, it is possible to create a system which results in less time and less cost in order to replace the inconvenient and expensive method.Master Thesis A Dedicated Server Design for Physical Web Applications(Izmir Institute of Technology, 2019) Abdennebi, Anes; Ayav, TolgaWith the huge impressive technological improvements the world is witnessing where giants like Facebook, Google, Apple, Microsoft and other technology companies are offering different services to millions of clients, services which don’t take usually more than seconds to be within the users’ devices besides the Physical Web applications that makes things interacts, having entities and can be reached based on the proximity context without omitting the incoming IoT infrastructure that would make 20.4 billion devices connected by 2020, the amount of data transferred, and services provided will be enormous and along with that, the big energy consumer standing behind providing clients with the needed data and services instantly, the web servers. Although it has a magnificent performance and responds to billions of queries and requests, however, there is still a crucial point which must be highlighted, the remarkable amounts of energy consumption by these servers. Therefore, this work is proposing a new approach in order to reduce the energy consumption in such a scenario where the 18-core energy efficient computer Parallella board will be used in order to create an energy efficient server that can offer many services triggered by various devices or any ordinary web requests across any environment and to prove also that using a cluster of Parallella supercomputers may perform as other similar servers dealing with web content (e.g. Raspberry Pi server). We will show how would these boards work under low energy feeding where users can access a web content hosted on a Parallella cluster. The source codes of the project are available on GitHub.Master Thesis Housing Production in the Last Thirty Years and Housing Question of the Poor in Izmir(Izmir Institute of Technology, 2019) Uysal, Ayça; Avar, AdileIn this thesis, housing production in the last thirty years and housing question of the poor in İzmir is examined. The case study focuses on the squatter housing area in İkinci İnönü Neighborhood that has been suppressed by the luxury housing development and was declared as the urban transformation area under the Redevelopment of Areas Under Disaster Risk Law (no. 6306) by Narlıdere Municipality in 2013. The squatter housing development in İzmir started as the solution by the poor for the housing problem. Particularly in the last ten years, the urban transformation projects that aim to renew and transform the squatter housing areas resulted in exclusion through dispossession of the poor. The research problem is whether the poor can enter into the housing market; how and in what ways they articulate to the system; and what waits for them after the urban renewal project that would be carried out in the area. Accordingly, a field research was conducted. It was a methodologically pluralist work covering field survey, visual documentation, in-depth interviews with squatter housing inhabitants, the mukhtar and municipal authorities, focus group interviews, household questionnaires and interviews, and institutional data collection. The findings of the research indicate that the urban transformation project carried out in the squatter housing area will result in the exclusion and displacement of the poor. The project addresses to higher income groups, is market-oriented, and insensitive to the economic, social and cultural characteristics of the inhabitants of the area. The project will be carried out by the 50% shareholding partnership of Narlıdere Municipality and a private company. Although the urban transformation project has been submitted to the approval of the Ministry of Environment and Urbanization, there is no agreement that specifies the title deed right of the residents.Master Thesis Inclusive Design for Public Space in Basmane, Izmir: Psychogeography as a Design Method for Urban Furniture(Izmir Institute of Technology, 2019) Ertürk, Aylin; Tunç Fox, Ayçaİzmir is a city that has attracted immigrants throughout the history, and Basmane in particular, has functioned as a transition hub in İzmir Basmane is a multicultural, multilingual and multiethnic district in İzmir People from different cultures and ethnicities live in this district. In such a district, people may need to have hospitality and a friendly atmosphere to live in harmony. The changes of living conditions and social structure due to mass migration, the design of urban space has become more important. It can be provided improvement people's quality of life and standards, contribution to society, creation of hospitable environment, and the feeling of belonging with urban space design. Urban furniture is the integral element of urban public spaces. Urban furniture is expected to meet human needs in public spaces. This study examines inclusive design in order to analyze the principles of urban furniture design. In order to get inclusive design approach and the accurate data of Basmane district, psychogeography was used as a design method. A questionnaire was conducted to reach out people and gather data regarding their needs in Basmane. With the consideration of the results of the dérive experience and based on the findings of the questionnaire, a suggestion of inclusive urban furniture design was shaped.Master Thesis Corporate Social Responsibility in the Construction Industry(Izmir Institute of Technology, 2019) Doğan, Ceren; Kale, SerdarThe concept of “Corporate Social Responsibility” is one of the most discussed and debated issues in literature. It argues that firms should behave responsibly to the environment, society, and all stakeholders. Construction firms have been relatively slow, compared to firms operating in other industries, in adopting “Corporate Social Responsibility (CSR)” practices. Yet it is a topical managerial issue for construction firms. The main objective of the research present in this thesis is to explore the concept of Corporate Social Responsibility practices in the context of construction industry. The sample used in this thesis is composed of 205 construction firms listed in ENR‟s 2018 Top 250 International Contractors. CSR discourses of construction firms are explored by using content analysis of CSR reports, financial reports, corporate web pages and other web sources. The research findings suggest that CSR practices/discourses used in the construction industry can be categorized into nine major groups. The most common CSR practices/discourses used in construction industry focuses on customer issues, environmental issues and labour issues. Research results also highlight that nationality of the firms, continent in which construction firms located and the ranking of construction firms in ENR list have significant impact on the use of CSR practices/discourse.Master Thesis Blue growth in Izmir Peninsula(Izmir Institute of Technology, 2019) Coşkunışık, Ceren; Velibeyoğlu, KorayThe trend towards exploiting natural resources caused by urbanization and increasing population has recently started to attract significant attention. In particular, it is the 'Blue Growth' concept, a subject not previously considered in the field of planning, for which the European Union has started to develop holistic and sustainable policies. In traditional planning studies, the terrestrial and coastal areas are considered as a whole and the marine areas are excluded from the planning. The seas, however, cover a large part of the city and its habitats. In marine areas such as the terrestrial areas; The regions that need to be protected, the species that need to be protected, the regions that are formed according to the diversity of the areas of use, and the regions that need to be used by the sectoral diversity. In this study, people from different institutions and organizations involved with marine areas were interviewed by using qualitative data collection method. The study aims to raise awareness about marine areas, to give information about the European approach in dealing with marine areas and to show that the seas should be considered together with land and coastal planning in Turkey. Therefore, in this study, we investigated how the sea areas are used, which laws and regulations are applied to the seas, which sectors and which stakeholders are involved with the sea. Then, maritime areas were examined on the Izmir peninsula in the framework of marine tourism and aquaculture and fishing. As a result of this study, we hope to increase awareness about the marine areas to be included in the field of planning and we will suggest our ideas about the holistic planning approach. This study will provide guidance on the marine environment and legal regulations for future studies.Master Thesis Distance Estimation in Tabletop Molecular Communication(Izmir Institute of Technology, 2019) Uzun, Emrehan; Atakan, BarışAlthough existing communication technologies based on electrical and electromagnetic signals are applicable for a variety of applications, these technologies are insufficient in some applications. Especially, developments in nanotechnology and biotechnology require an alternative communication paradigm. Molecular communication (MC) paradigm is a promising solution needed to fill the gap in both nano- and macroscale. It is one of the oldest communication paradigm in which molecules are used as information carrier. Its mechanism provides a basis for all living organisms from unicellular bacteria to humankind to continue their existence. For instance, the information transfer among nerve cells is accomplished via MC. These kind of biological activities inspire a base for communication between nanomachines. The realization of MC occurs by sending and receiving molecules between nanomachines. The information about distance between transmitter (Tx) and receiver (Rx) is one of the critical points to enable an efficient performance in terms of clock synchronization, transmission rate, etc. in the design of MC system. However, most of the existing works on MC are based on the assumption distance is pre-known. In addition, the proposed theoretical methods are validated using an ideal simulation environment. Furthermore, there is a limited number of studies about macroscale practical applications. In this thesis, an end-to-end tabletop MC testbed is established to transmit chemical signals from a Tx to Rx. This testbed allows us to provide an estimate about the distance using molecular information received by the Rx. In the development of the estimation algorithms, the principles of molecular random walk are used. We propose three novel approaches that are called as peak time, correlation based and relative entropy based approaches to estimate the distance between Tx and Rx for a practical MC system. The performance of the proposed estimation methods is evaluated in the tabletop MC testbed. The experimental results shows that our proposed methods present a satisfactory performance in terms of estimation error and the methods can be used to develop new potential macro-scale MC applications.
