Smart cities are one of the promising application areas where the energy management (supply/dispatch) issues have the potential to positively affect the society. In the common era of information and technology, the consumers expect the required amount of energy to be present at anytime. This energy is obtained through renewable and nonrenewable resources. Smart wind energy is the idea of efficient energy generation utilizing the wind while satisfying green expectations. However, the random characteristics caused by various external factors have significant effects on wind speeds, thus introducing difficulties in power systems operations and energy generation. Forecasting techniques can be effectively used to predict future wind speeds and power generation to optimize the energy output. The objective of this study is to provide a framework for a local smart-city wind energy harvesting model. Our study evaluates wind speed forecasting models based on synced weather characteristics (air temperature, humidity, and pressure), against models based on wind speed data itself. The produced models are implemented via k-nearest neighbors and linear regression. Two different data sets are addressed for performance comparison purposes. The first one is 5 years of 10-minute time span measurements at Middle East Technical University campus. The second data set is 3 years of the same time span at a site in California, USA. The accuracy of predictions is found to be higher for the data sets with lower variance (METU data set). However, the models fit the higher variance (NREL data set) data better than the lower one.

Acceptance of IoT-Based and Sustainability-Oriented Smart City Services: A Mixed Methods Study
Beştepe, Fırat; Özkan Yıldırım, Sevgi (2022-02-01)
Smart cities (SC) have emerged as a hope for urbans that face challenges and sustainability issues due to rapid urbanization. SC services can make the daily routines more efficient, create more public value, and improve the urban sustainability and life quality (QoL). However, before any technology enters the market, the factors making adoption easier for the end-users should be examined. Here, we aim to examine the acceptance of IoT-based and sustainability-oriented SC services. This study proposes a SC se...
ANALYZING THE RELATIONSHIP BETWEEN DISASTER RISK MITIGATION AND URBAN PLANNING PROCESSES: THE CASE STUDY OF ESKISEHIR CITY
Sert Özkiremitçi, Merve; Balaban, Osman; Department of City and Regional Planning (2022-5-11)
The aim of this study is to discuss the effectiveness and efficiency of urban planning in reducing the risk of natural disasters in cities and to analyse the relationship between planning and disaster mitigation processes. The study focuses particularly on the analysis of Eskişehir case with reference to data and information on disaster risk analysis, existing urban development plans as well as the plan implementation processes. After the 1999 Gölcük and Düzce Earthquakes, Eskişehir has also faced and to a ...
Finding sustainable mobility solutions for shrinking cities: the case of Toyama and Kanazawa
Balaban, Osman (2021-11-01)
Purpose Shrinking population can have significant negative impacts on the social and economic fabric of a city. This paper aims to understand different urban transportation policies to respond to population decline in shrinking cities by examining two case studies of urban interventions in mid-size cities in Japan. Design/methodology/approach The paper analyzes the implementation of sustainable mobility strategies in the urban transport sector in the Japanese cities of Toyama and Kanazawa, which risk having...
Increasing walkability in public spaces of city centres: the case of Tunali Hilmi Street, Ankara
Ghadimkhani, Parisa; Akkar Ercan, Zübeyde Müge; Department of City and Regional Planning (2011)
Liveability and walkability have recently become one of the major policy topics in the agenda of many cities all over the world because of the negative effects of car-oriented urban developments that have impoverished physical, social, cultural, economic and environmental values of cities. In Ankara, however, the urban development policies based on the decentralization of the city centre and inner city, the impoverished public transportation services and infrastructure, the increasing car-dependent developm...
An overview of security and privacy in smart cities' IoT communications
Al-Turjman, Fadi; Zahmatkesh, Hadi; Shahroze, Ramiz (2019-07-08)
Smart cities have brought significant improvements in quality of life and services to citizens and urban environments. They are fully enabled to control the physical objects in real time and provide intelligent information to citizens in terms of transport, healthcare, smart buildings, public safety, smart parking, and traffic system and smart agriculture, and so on. The applications of smart cities are able to collect sensitive information. However, various security and privacy issues may arise at differen...
