    Computational Intelligence Based Point of Interest Detection by Video Surveillance Implementations

    Tercan, Emre; Tapkın, Serkan; Küçük, Furkan; Demirtaş, Ali; Özbayoğlu, Ahmet; Türker, Abdussamet

    Latest advancement of the computer vision literature and Convolutional Neural Networks (CNN) reveal many opportunities that are being actively used in various research areas. One of the most important examples for these areas is autonomous vehicles and mapping systems. Point of interest detection is a rising field within autonomous video tracking and autonomous mapping systems. Within the last few years, the number of implementations and research papers started rising due to the advancements in the new deep learning systems. In this paper, our aim is to survey the existing studies implemented on point of interest detection systems that focus on objects on the road (like lanes, road marks), or objects on the roadside (like road signs, restaurants or temporary establishments) so that they can be used for autonomous vehicles and automatic mapping systems. Meanwhile, the roadside point of interest detection problem has been addressed from a transportation industry perspective. At the same time, a deep learning based point of interest detection model based on roadside gas station identification will be introduced as proof of the anticipated concept. Instead of using an internet connection for point of interest retrieval, the proposed model has the capability to work offline for more robustness. A variety of models have been analysed and their detection speed and accuracy performances are compared. Our preliminary results show that it is possible to develop a model achieving a satisfactory real-time performance that can be embedded into autonomous cars such that streaming video analysis and point of interest detection might be achievable in actual utilisation for future implementations.

    Housing Demand Forecasting with Machine Learning Methods

    Emec, Seyma; Tekin, Duygu

    Housing is a place where sustainable urban spaces are produced and where people's physical, cultural, environmental, economic, social and psychological needs are evaluated together with their surroundings, rather than just a building where the need for shelter is met. With the acceleration of urbanization, new needs arise, and the first of these is the need for housing. The housing sector has become one of the most dynamic and continuous sectors associated with the increase in the need for housing. The need for adequate and accessible housing comes to the forefront in our country as well as in the world. Understanding and predicting the key features determining housing prices and value is an important consideration for urban planners and housing policymakers. In this study, machine learning and artificial neural network models were used to predict the housing demand of Konya, and their forecasting performances were compared. As a result, it was concluded that ANN is a better alternative for housing demand forecasting in Konya.

    The Effects of Urbanization, Life Expectation at Birth and Commercialization on Income Inequality: A Research on the Community of the Independent States and Some Baltic Countries

    Gültekin, Omer Faruk

    One of the important results of economic development is the development of trade and the increase in welfare. A reflection of the increase in welfare is the prolongation of human life and the increase in urbanization. Through these indicators, societies are expected to develop economically and socially. In this study, as a reflection of welfare, the effect of commercialization, average life expectancy and urbanization on income inequality in the Commonwealth of Independent States countries and some Baltic countries that gained independence after the dissolution of the Soviet Union after 1991 were investigated. In the study, trade openness and the share of countries in world trade representing commercialization, urbanization representing the increase in welfare, and disposable Gini coefficient and market Gini coefficient representing income inequality examined. For the estimations, four models were created and different results were obtained for each model. In the analysis process, descriptive statistics, correlation matrix, multicollinearity, cross-section dependence, heteroscadasticity, autocorrelation tests were applied. Depending on the test results, the Driscoll-Kraay test was applied and the results were estimated. According to the results, it can be said that while commercialization has a positive effect on income inequality, urbanization has a negative effect on income inequality.

    Seismic behavior assessment of historical Alaeddin Bey Mosque and strengthening suggestions by CFRP fabric and steel plate

    Şentürk, İdris; Ergün, Mustafa; Artar, Musa

    In this study, the effects of different strengthening methods that can be applied for earthquake-damaged historical masonry structures on structural performance were investigated. For this purpose, the Historical Alaeddin Bey Mosque in the central district of Muş was modeled in three dimensions according to the macromodeling technique using the finite element method in the SAP2000 program. The earthquake performance of the structure was determined by considering the earthquake-acceleration records of Erzincan, Kocaeli, and Van, respectively. The maximum tensile and compressive stresses in all three directions on the structural elements were taken into account as the earthquake behavior parameters of the structure. According to the earthquake analysis made in the time domain, it was determined that the polygonal pulpit of the minaret was at risk of being damaged under the effect of the Erzincan earthquake, and it has been concluded that this region should be strengthened. The damaged area of the minaret was strengthened by the application of CFRP fabric and steel plate materials (together or separately) in five different ways, from inside and outside and at different distance intervals. The conclusions obtained as a result of the earthquake analyses on the reinforced models were examined, and it was explained in detail with the help of tables and graphics that method would be more effective in strengthening such damages.

    Design of an efficient vehicle-actuated signal control logic for signalized intersections

    Cakici, Ziya; Murat, Yetis Sazi; Aydin, Metin Mutlu

    The effectiveness of fixed-time management systems dramatically decreases in case of fluctuating traffic demands in signalized intersection approaches. The result is the utter waste of time in traffic to be followed by material, psychological, and ecological problems. In recent years, to minimize the negative impacts of these problems, many researchers have focused on Intelligent Transportation Systems (ITS). As it is known, one of the applications of ITS is called vehicle-actuated (traffic-actuated) management systems. Because the success of these types of applications is directly related to the created control logic, the selection of the most proper control parameters for the created control logic is an important issue. This study aims to create an effective control logic and flow chart for the vehicle-actuated management system. At the end of the analyses, it is seen that the created vehicle-actuated management system can adapt to fluctuations in traffic demands in signalized intersection approaches. Average vehicle delays, fuel consumptions, and exhaust emissions can be reduced significantly by the created system. In case of fluctuations in traffic demands in intersection approaches, it is concluded that the performance of the intersection may increase enormously because of the created vehicle-actuated management system.

    Poverty and City Safety

    Alacadağli, Esmeray

    Children are people’s gateway to the future; they are 30.3% of the world’s population. Childhood is a stage that has a great impact on adulthood and children being healthy individuals. For this reason, child poverty and childhood conditions are very important for individual and community life. Cities are places where people live, and more than 50% of the world’s population lives there. In the cities, whose numbers and sizes have increased over time, the crimes committed have also increased and diversified. For this reason, it has become increasingly difficult to provide urban security today. The aim of this study is to show the relationship between child poverty and urban safety, by carrying out an overview of the global perspective and examining the case of Turkey.

    Determination of the gas/particle phase concentrations of PCBs in urban and rural atmosphere in Erzurum, Turkey

    Paloluoğlu, Cihan; Bayraktar, Hanefi

    Active sampling was conducted for the first time in Erzurum, Turkey, between August 2012 and January 2013, in order to investigate the presence of 82 polychlorinated biphenyls (PCBs) congeners. Urban and rural ambient air samples, including gas and particle phase atmospheric concentrations (GAPPACs) of PCBs, were collected simultaneously using high volume air sampler (HVAS) at two different sampling points of Erzurum. GAPPACs of PCB samples taken using HVAS in Palandöken Mountain Region (2565 m) and Ataturk University Campus (1870 m) were analyzed in GC–MS following appropriate extraction steps. Throughout the sampling period, total ambient air concentrations (gas phase + particulate phase) were 10 ± 6 and 27 ± 13 pg/m3 (mean) for Palandöken Mountain Region (PMR) and Atatürk University Campus (AUC), respectively. Low molecular weighted PCBs were found to be dominant in both rural an urban sampling sites. Meteorological parameters especially temperature (from Clausius–Clapeyron equation), wind direction, wind velocity, and precipitation were found to be effective on PCB concentration and distribution. The gas-particle distributions of PCBs in the summer and winter period were found to be 82% (gas phase) and 18% (particle phase) in the PMR and 90% (gas phase) and 10% (particle phase) in AUC, through Junge-Pankow adsorption model. In the light of these findings, total PCB concentrations detected in urban atmosphere (due to possible PCB sources) were observed to be higher than those determined in rural area.

    Contribution of University Students' Urban Consciousness and Urban Rights Awareness toUrbanization and Urban Culture; Example of Bayburt

    Alacadağlı, Esmeray

    : Urbanization is a process that involves change and organization and has socio-cultural consequences. Themost important of these results is the emergence of a city-specific lifestyle and culture called urbanization. However,in urban settlements that are not based on industrialization or created by political decisions, urbanization can realiseunhealthy or distorted and so urban behaviors and lifestyle cannot occur. Bayburt, which became a province in 1989,is a city that is in the process of urbanization and development. According to the "Provinces and Regions Socio Economic Development Survey", Bayburt, is in the fifth degree group of developed provinces with low agriculturalproductivity and hidden unemployment problem in the agricultural sector. Emigration is a factor that supports thelivelihood of the province. However, there is a positive development in the economic indicators per capita andmigration rates in Bayburt after becoming a province. Per capita national income increased from $ 708 in 1990 to $1019 in 1996. Between 2012 and 2013, Bayburt is now a province receiving immigration with a net immigrationrate of ‰ 1,46. In this positive development, the share of students and academicians who came to the city withBayburt University was opened in 2008, is a phenomenon that has been revealed by researches and is generallyaccepted. The main mission of universities is actually education and research. However, these institutions can makevaluable contributions to the economic, social and cultural development of a city, depending on the size, populationand level of other functions of the cities in which they are located. The purpose of this study is to reveal to whatextent Bayburt University students coming from different cities and carrying the cultural elements of that city hadan impact on the culturalization of their urban behaviors and the urbanization of Bayburt. For this purpose, aliterature review has been made and a questionnaire and interviews were conducted in order to measure theawareness and sensitivity of the students and citizens about urbanization and urban rights and to reveal to whatextent they do these

    Non-Urbanization and Social Dynamics of Violence against Women

    Alacadağlı, Esmeray

    Urbanization is a concept that defines the increase in the population living in cities in terms of demographics. In Turkey, the number of individuals living in urban areas increased continuously after the 1950s and reached around 93% as of today. However, urbanization also has economic and social dimensions. Because, rapidly increasing urbanization without sufficient infrastructure and demand generally leads to formation of cities with underlying unemployment, and the emergence of a social structure that is urbanized but not localized, ultimately not being able to integrate with the city. Generally, this social segment tries to survive by settling in the urban suburbs, consists largely of the masses who are not able earn their living with urban-jobs, and who ultimately cannot adopt urbanspecific behaviors, lifestyles and values. Hence, these masses try to survive in the city and with the dominant values of the places they came from, instead of integrating to the city culture, which leads to their alienation to city values, resulting alienation and potential tendencies towards violence due to increasing marginalization.This literature review-based study aims to provide solutions by analyzing the causes of the violence against women, which has recently been increased in our society, in the context of migration, urbanization and poverty phenomenon. Research results reveal the importance of nonurbanization and poverty, as being factors for violence against women.

    Clustering framework to cope with COVID-19 for cities in Turkey

    Guleryuz, Didem; Ozden, Erdemalp

    Introduction: This article is the product of the research Clustering Framework to Cope with COVID-19 for Cities in Turkey, developed at Bayburt University in 2021. Problem: Turkey's risk map, presented in January 2021, to take local decisions in tackling the COVID-19 pandemic, was based on confirmed cases only. Health, socio-economic and environmental indicators are also important for management decisions of COVID-19. The risk map to be designed by adding these indicators will support more effective decisions. Objective: The research aims to propose a clustering scheme to design a risk map of cities for Turkey. Methodology: The unsupervised clustering algorithm suggested dividing the cities of Turkey into clusters, considering health, socio-economic, environmental indicators, and the spread pattern of COVID-19. Results: We found that cities are clustered into five groups while megacity Istanbul alone formed a cluster, three of Turkey's largest cities formed another cluster. Other clusters consist of 19, 26, and 32 cities, respectively. The most important determinants which have predictive power are identified. Conclusion: The suggested clustering method can be a decision support system for policymakers to determine the differences and similarities of cities in quarantine decisions and normalization phases for the following periods of the pandemic. Originality: To the best of our knowledge, this study differs from previous studies because countries were grouped in previous studies by only considering the confirmed cases. In this study, cities were clustered in terms of the health, socio-economic, and environmental indicators to make decisions locally. Limitations: The distribution of confirmed cases by age could be added, especially to make decisions about education, but this data is not officially announced.

    Cittaslow: Umbrella branding for Turkish cities

    Sengün, Hayriye; Kara, Adnan

    Cittaslow is an international movement against one of the biggest problems of today, i.e. the effects of dense human population and fast urban life.The study aims to clarify the city branding practices of local governments participating in Cittaslow, and to examine the economic, social and environmental impacts that the movement exerts on cities. In conceptual framework, the Cittaslow movement is explained with its basic philosophy and policies, and city branding is discussed within the image and positioning concepts. The research includes quantitative evaluation of simple statistical data such as mean and standard deviation. The study covers cities in the Turkish Cittaslow network and applies an online questionnaire with the municipality officials. Items related to the importance and social, economic, environmental aspects of Cittaslow are included in the online survey.The research results prove that the economic and social aspects of the Cittaslow movement are more positive for the cities, whereas the environmental aspects are less positive. The Cittaslow movement strengthens the brand image of small towns with associations of territories' cultures and traditions. The authors find that, while preserving local values, urban regeneration can be made with positive city image.

    Investigation of time-history response of a historical masonry minaret under seismic loads

    Yurdakul, Muhammet; Yılmaz, Fatih; Artar, Musa; Can, Ömer; Öner, Erdal; Daloğlu, Ayşe T.

    This study presents an investigation of the seismic performance of a historical masonry minaret which was built in the 12th century in Bayburt. The minaret was built as masonry with regional stones and handmade bricks. The most important feature of the minaret is its longitudinally conical geometry. An experimental investigation was made to obtain the mechanical properties of the regional stone used in the historical minaret. A three-dimensional Finite Element Model of the historical minaret was created in SAP2000. Three earthquake ground motions such as Erzincan, Kocaeli-Duzce, and Van-Ercis were used to investigate the seismic performance of the historical minaret. The results show that Erzincan, Kocaeli-Duzce and Van-Ercis earthquakes may cause some damages in the same zone of the minaret body since the tensile stresses occurred due to the earthquakes exceed the limit tensile stress of the masonry brick. The use of the data obtained from the experimental investigation of the Bayburt yellow stone in the analysis is important for the reliability of the results.

    The investigation of flood risk perception as a quantitative analysis from socio-demographic perspective

    Eryılmaz Türkkan, Gökçen; Hırca, Tuğçe

    The priority of flood management planning is physical victimization and focuses on taking structural measures. Although this approach is an accurate approach, more information is needed in implementing efficient precautionary and planning decisions. It is an indisputable fact that the existence of nothing that is not sustainable in nature cannot continue. Hence, it is necessary to implement a planning decision suitable for the structure of the population living in the region so that the continuity of the policies to be carried out against natural hazards of hydrometeorological origin such as a flood is ensured. How the socio-demographic structures affect the flood risk perception of 245 people living in the city center of Bayburt is examined in this study. It is the first research conducted for the province of Bayburt for this perspective. The participants were asked to fill a questionnaire containing 24 items and consisting of 2 sections. T test and one-way ANOVA (one-way analysis of variance) statistical methods were used to ascertain the difference between the responses of the participants to the questionnaire, based on their demographic structure. As the result of the study, significant differences were observed between the expressions depicting flood risk perception and the participant's age, income levels and educational background. In addition, it has been noted that there is a positive relationship between education and income levels and flood risk perception.

    Cycling as transportation & COVID-19: Advantages of shared bicycles during epidemics

    Saatchian, Vahid; Azimkhani, Amin; Türkmen, Mutlu; Laein, Dorri Dolatkhah

    In addition to the environmental problems that have plagued human life in recent decades, the outbreak of the coronavirus epidemic has endangered people's health and adversely affected their lives in other ways. Therefore, the present study aimed to investigate the advantage of using shared bicycles (SB) during the outbreak of epidemics. For this purpose, 310 male subscribers of an SB system were examined. The research tool was a questionnaire taken from studies. The results showed that the environmental and health advantages were favourable, but the place advantage indicated a relatively unfavourable situation. The results of the structural equation model also showed that the advantages of using an SB based on the highest impact are the motivational advantage, health advantage, environmental advantage, social advantage, financial advantage and place advantage. These results can provide useful solutions for governments to reduce environmental risks and maintain health and physical activity during epidemics.

    Municipal solid waste-based district heating and electricity production: A case study

    Tozlu, Alperen; Abusoglu, Aysegul; Ozahi, Emrah; Anvari-Moghaddam, Amjad

    In this paper, municipal solid waste (MSW) based electricity production and district heating (DH) potential of Turkey are considered. Three MSW based waste-to-energy (WtE) scenarios is developed: (i) Scenario-I, a DH system integrated into a gas turbine power plant (GTPP), (ii) Scenario-II, a DH system integrated into an organic Rankine cycle (ORC), and (iii) Scenario-III, which is based solely on a DH system. As a result of the thermodynamic and thermoeconomic analyzes of these developed scenarios using an existing MSW-based cogeneration facility's actual operating data, the system with the most extended payback period (about 5 years) is found as the GTPP-DH system developed in Scenario-I, which also has the highest investment cost. On the other hand, the system with the shortest payback period (about 2 years) is found as the DH system developed in Scenario-III, which also has the lowest investment cost. Overall exergy efficiencies of the GTTP-DH, ORC-DH, and DH systems are found to be 41.86%, 16.15%, and 31.87%, respectively. When the developed WtE scenarios adapted to the pilot provinces selected from each geographical region of Turkey, it is found that the GTPP system developed in Scenario-I can increase the power generation capacity of MSW plants for each province by about 20%.

    An analysis of the role of the social acceptance of university students’ bicycle use in sustainable urban development when epidemics spread

    Saatchian, Vahid; Azimkhani, Amin; Honari, Habib; Türkmen, Mutlu

    The purpose of this study was to investigate the role of the acceptance of university students’ bicycle use in sustainable urban development in Iran when epidemics spread. The research method was descriptive-correlational, and the investigation was carried out as a field study. The statistical population of the study consisted of university students, 254 of whom were selected by a simple random sampling method to participate in the research. The research instrument was a questionnaire based on the Sustainable Development with a reliability coefficient of 0.83; the social acceptance component was based on the theory of planned behaviour with a reliability coefficient of 0.8. As the results of the investigation have demonstrated, the bicycle plays a significant role in the development of the socialization process of people, and there is a positive and significant relationship between social acceptance and sustainable development (p<0.05). Furthermore, 20% of sustainable development change was achieved through the dimensions of social acceptance (planned behaviour theory). Finally, it can be argued that perceived behaviour in social acceptance is most likely to play a significant role in the emergence of sustainable development by external factors such as encouragements and persuasion of the family, important people, friends, acquaintances, and even by the existing norms in society. Subsequently, as people change their mindset when epidemics spread, they can turn all the behaviours they manifest in their leisure time into a culture development movement.

Bu çalışmada uçucu kül ve mermer tozu atıkları, katı atık yönetimi kapsamında zemin stabilizasyonu için kullanılmıştır. Çalışma kapsamında, düşük plastisiteli killi bir zemine %25 uçucu kül ve sırasıyla %0, %5, %10, %15, %20 oranlarında mermer tozu ilave edilmiştir. Hazırlanan karışımların indeks ve dayanım gibi geoteknik özellikleri irdelenmiştir. Ayrıca, katkı maddelerinin zeminin donma-çözülme çevrimi sonucundaki dayanım değerlerine etkisi incelenmiştir. Çalışma sonucunda, uçucu kül+mermer tozu karışımlarının sadece uçucu kül içeren karışımlara göre daha yüksek dayanım sağladığı sonucuna varılmıştır.
