    A study on the energy problem in the eastern mediterranean: Text mining and AHP-based strategy recommendations
    (Springer Science and Business Media Deutschland GmbH, 2021) Yüksel, Serhat; Eti, Serkan; Prosekov, Sergey; Uluer, Gülsüm Sena
    The American Geological Association has made some estimates for reserves in the Eastern Mediterranean region. According to these estimates, it is predicted that there are very high amounts of natural gas and oil resources in the deltas of Nile, Levant and Aphrodite. These figures are large enough to meet Europe’s 10-year natural gas need. On the other hand, another important point in this process is that these reserves are the amount determined in the studies conducted so far. In other words, there is a possibility that the actual reserve amount in this region is well above the estimated. Investigations in the relevant region are ongoing. As a result of these investigations, there is a possibility that new reserves will be identified. Because of this situation, there are many countries engaged in energy exploration in the Eastern Mediterranean. Firstly, the countries, which have a border to this region like Turkey, Israel, Egypt, the Turkish Republic of Northern Cyprus, Cyprus, Greece, Lebanon, Syria and Libya, are very active in this region. In addition, although there is no border to the region, countries such as the USA, Russia, England, France and Italy want to maintain their weight in the energy equation in the Eastern Mediterranean. It is obvious that the size of the energy reserves in the region lies at the heart of the energy struggle in the Eastern Mediterranean. This situation causes an increase in political tensions between some countries operating in the region. No country wants to give up this economic size. Therefore, some countries like Turkey-Greece and Libya-Egypt have problems with each other. The aim of this study is to develop strategies to reduce the political tension between countries due to energy reserves in the Eastern Mediterranean region. In this context, an analysis has been carried out by considering data mining and AHP methods in a hybrid way. The analysis process in question consists of 2 different stages. In the first process of the analysis, the most common words in academic studies are categorized using the LDA model. In this framework, 4 different categories are created. In the second phase of the analysis, more important factors are determined with the help of AHP method. The findings indicate that political relationship is the most significant factor to solve the conflict in Eastern Mediterranean region. Furthermore, transportation also plays a key role in this framework. Nevertheless, energy production and reserve amount have lower important roles to minimize this problem. Considering these results, ways of establishing positive relations between all countries in the region should be sought. Searching for a reconciliation with the energy companies making exploration, as well as with the countries, may contribute to solving the problems in the region.

    Can digitalized financial products increase thorium-based nuclear energy investments
    (Springer Science and Business Media Deutschland GmbH, 2023) Dinçer, Hasan; Yüksel, Serhat; Yavuz, Duygu; Mikhaylov, Alexey; Prosekov, Sergey
    The production and consumption of energy are among the most significant variables that may be used to determine a country’s degree of development. Nuclear energy investments play a critical role for the energy independence. However, nuclear power plants are criticized because of some issues, such as radioactive wastes. In this framework, nuclear power plants can also be worked with thorium instead of uranium so that this problem can be minimized. The biggest obstacle to the realization of green nuclear energy projects is the high costs. To solve this problem, it is important to provide the necessary financing for these investments. In this process, it is seen that financial institutions operating in the market do not meet this need. Financial institutions may be reluctant to finance these projects with very high amounts and uncertainties about their success. There is a need for innovative financial products. It is possible to mention some advantages of presenting these financial products in digital environment. In this way, more investors will be reached. Therefore, it will be possible to have a higher amount of funds. On the other hand, it will be possible to get rid of some fixed costs because of the realization of the transactions in the digital environment. This will also contribute to the reduction of costs. Thus, green nuclear energy investors will be able to access much lower cost loans.

    The ways to improve nuclear cybersecurity for zero emission
    (Springer Science and Business Media Deutschland GmbH, 2022) Yüksel, Serhat; Atasoy, Esma Nur; Vatandaş, Esma; Prosekov, Sergey
    Cybersecurity is another important issue for nuclear power plants. Modification of data by unauthorized persons can cause serious problems in nuclear power plants. In this context, it is vitally important to take the necessary precautions by producing the most accurate strategy. This chapter aims to generate appropriate strategies for the nuclear energy investors to enhance cybersecurity. In the analysis process, DEMATEL approach is taken into consideration. Increasing technological investments plays the most significant role to improve cybersecurity in nuclear power plants. Hence, the priorities should be given for the technological investments. This situation helps to create more effective nuclear energy investments. It is necessary to ensure the cybersecurity of nuclear power plants by making technological investments. Better technological investments will help to better provide the infrastructure to be protected from these risks. Otherwise, power outages may occur as a result of changing the data of nuclear power plants. This will reduce the efficiency of the electricity generation process. On the other hand, as a result of cyberattacks, it is possible that nuclear reactions cannot be stopped. This increases the probability of an explosion at the nuclear power plant.
