Crime is a behavior disorder that is an integrated result of social, economical and environmental factors. In the world today crime analysis is gaining significance and one of the most popular subject is crime prediction. Stakeholders of crime intend to forecast the place, time, number of crimes and crime types to get precautions. With respect to these intentions, in this thesis a spatio-temporal crime prediction model is generated by using time series forecasting with simple spatial disaggregation approach in Geographical Information Systems (GIS). The model is generated by utilizing crime data for the year 2003 in Bahçelievler and Merkez Çankaya police precincts. Methodology starts with obtaining clusters with different clustering algorithms. Then clustering methods are compared in terms of land-use and representation to select the most appropriate clustering algorithms. Later crime data is divided into daily apoch, to observe spatio-temporal distribution of crime. In order to predict crime in time dimension a time series model (ARIMA) is fitted for each week day, Then the forecasted crime occurrences in time are disagregated according to spatial crime cluster patterns. Hence the model proposed in this thesis can give crime prediction in both space and time to help police departments in tactical and planning operations.

Evaluating the use of satellite-based precipitation estimates for discharge estimation in ungauged basins Soytekin, Arzu; Akyürek, Sevda Zuhal; Department of Civil Engineering (2010) For the process of social and economic development, hydropower energy has an important role such as being renewable, clean, and having less impact on the environment. In decision of the hydropower potential of a study area, the preliminary condition is the availability of the gages in the area. However, in Turkey, the gages in working order are limited and getting decreased in recent years. Therefore, the satellite based precipitation estimates has been gaining importance to predict runoff for ungauged basi...
Modelling Energy Consumption of the Republic of Serbia using Linear Regression and Artificial Neural Network Technique Protic, Milan; Fathurrahman, Fahman; Raos, Miomir (Mechanical Engineering Faculty in Slavonski Brod, 2019-02-01) The objectives of the study are twofold. First, we aim to examine the most influential socio-economic indicators to explain energy consumption in Republic of Serbia. The second objective is to develop models that are able to predict the future energy consumption in the Republic of Serbia. This could be the first important step towards proper energy management in the country. Several potential socio-economic indicators are selected to be the independent variables. Regression analysis is conducted to select t...
Modeling Environmental Literacy of University Students Teksöz, Gaye; Şahin, Elvan; Öztekin, Ceren (Springer Science and Business Media LLC, 2012-02-01) The present study proposed an Environmental Literacy Components Model to explain how environmental attitudes, environmental responsibility, environmental concern, and environmental knowledge as well as outdoor activities related to each other. A total of 1,345 university students responded to an environmental literacy survey (Kaplowitz and Levine in Environ Educ Res 11:143-160, 2005). The structural equation model revealed that high levels of environmental knowledge stimulate a university student's concern,...
Performance evaluation of existing medium rise reinforced concrete buildings according to 2006 Turkish Seismic Rehabilitation Code Düzce, Zeynep; Sucuoğlu, Haluk; Department of Civil Engineering (2006) Linear elastic and nonlinear analysis procedures of 2006 Turkish Seismic Rehabilitation Code are applied to medium rise reinforced concrete buildings. In this study, four storey residential buildings are designed according to the 1998 and 1975 Turkish Seismic Design Codes, and the analysis procedures are verified on these case studies. In addition to these buildings, the analysis procedures are tested on an existing school building before and after retrofitting. The assessment procedures employed in the 200...
Institutionalization of construction firms: Turkish contractors’ experience Yavuzyılmaz, Özlem; Birgönül, Mustafa Talat; Department of Civil Engineering (2010) Literature studies on institutionalization are mainly predicated on repetitive work performing sectors, in which firms are more prone to developed institutionalization processes in literature. But, in this study, it is aimed to examine reasons behind low tendency of construction firms to institutionalization process in Turkey. In literature, two main obstacles against institutionalization are shown as firms’ resistance to change and founder family acts on firm. So, family businesses and their effects on fir...
