Forecasting of solar radiation using different machine learning approaches

DEMİR, Vahdettin | ÇITAKOĞLU, Hatice

In this study, monthly solar radiation (SR) estimation was performed using five different machine learning-based approaches. The models used are support vector machine regression (SVMR), long short-term memory (LSTM), Gaussian process regression (GPR), extreme learning machines (ELM) and K-nearest neighbors (KNN). Modeling of these approaches was carried out in two stages. In the first stage, VIF analysis was carried out to develop the model. Thus, the input parameters that decrease the performance of the model are removed. In the second stage, remaining input parameters such as meteorological ...Daha fazlası

Developing numerical equality to regional intensity–duration–frequency curves using evolutionary algorithms and multi‑gene genetic programming

ÇITAKOĞLU, Hatice | DEMİR, Vahdettin

This study aims to carry out regional intensity−duration−frequency (IDF) equality using the relationship with IDF obtained from point frequency analysis. Eleven empirical equations used in the literature for seven climate regions of Turkey were calibrated using particle swarm optimization (PSO) and genetic algorithm (GA) optimization techniques and the obtained results were compared. In addition, in this study, new regional IDF equations were obtained for each region utilizing MultiGene Genetic Programming (MGGP) method. Finally, Kruskal–Wallis (KW) test was applied to the IDF values obtained ...Daha fazlası

Determination of COVID-19 Phobia Level in Health Care Workers

YAVUZ BAŞKIRAN, Deniz | BAYIR, Berna | PEHLİVAN, Erkan

The aim of this study is to determine the COVID-19 phobia level in healthcare workers. The socio-demographic characteristics form and the Coronavirus 19 Phobia (CP19-S) Scale were used as data collection tools. The surveys were shared online on social media. 467 healthcare workers who agreed to participate in the study were reached. Employees who got 55.30 ± 14.64 points from the scale total scores and university graduates were found to have an average of 55.51 ± 14.11, and their families averaged 57.84 ± 15.05. As a result, it was determined that the COVID-19 phobia levels of healthcare worke ...Daha fazlası

Terrorism and Tourism: An Empirical Exemplification of Consequences of Terrorist Attacks on Tourism Revenues in Turkey

KAYA, Mustafa Göktuğ | ONIFADE, Stephen Taiwo | AKPINAR, Ayhan

The booming tourism sector in Turkey has resulted in major economic gains in terms of direct revenues to both government and private sectors alike. Turkey had more than 45 million visits in 2018, and top inbound arrivals were from Russia and European Union (EU) members, such as Germany, the United Kingdom, and Bulgaria, among others (Organization for Economic Co-operation and Development [OECD], 2020). However, terrorism is becoming a challenge to tourism development. This study explores terrorism–tourism dynamics in Turkey. The short- and long-run impacts of terror attacks on tourism revenues ...Daha fazlası
