Trend Analysis of Low Flows

Selen Orta

Determination of trends in low flows has a great importance in water resources planning and operation. Hydrological assessment on low flows is required in water quality control problems, water supply projects, irrigation, recreation, and ecological conservation. Trends in low flows could be seen as potential evidences of climate change, and significantly affect short-, medium-, and long-term future decisions. The main objective of this study is to identify low flow trends for gauging stations in four hydrological basins, Meriç-Ergene, Gediz, Ceyhan and Seyhan, from different regions in Turkey. ...Daha fazlası

Distance-Based Decision Making, Consensus Building, and Preference Aggregation Systems: A Note on the Scale Constraints

İbrahim Gürler | Bora Gündüzyeli | Ozan Çakır

Distance metrics and their extensions are widely accepted tools in supporting distancebased decision making, consensus building, and preference aggregation systems. For several models of this nature, it may be necessary to elucidate the problem output in the original input domain. When a particular parameter of interest is desired to be produced in this original domain, i.e., the scale, the decision makers simply resort to constraints that function in parallel with this goal. However, there exist some cases where such a membership is guaranteed by the mathematical properties of the distance ...Daha fazlası

Some Generalized Results on Grey Number Operations Based on Liu-Lin Axioms of Greyness Degree and Information Content

Ozan Çakır | İbrahim Gürler | Bora Gündüzyeli

In this manuscript, with grounding in Liu–Lin axioms of greyness degree and information content, we provide new results that relate to these concepts in consideration of a number of mathematical operations over a sequence of grey numbers. In particular, we derive greyness degree results of summation, conic combination, and convex combination of a sequence, as well as inverse of a number and normalization of a number over a sequence. Then, we turn our attention to prove information content results for the union and intersection of a sequence. We illustrate our results by using a simple Monte Ca ...Daha fazlası

A hierarchical clustering based panel data approach: a case study of regional incentives

Fatma Altuntaş

The main objective of this research is to propose a novel approach based on panel data analysis and hierarchical cluster analysis to investigate the determinants of foreign trade deficit and cluster provinces of Turkey. This study has two important contributions into the existing literature. First, the proposed approach uses provinces based panel data. Second, the proposed approach uses structural factors as explanatory variables. The estimates show that the number of patent, trademark, and design granted, the number of incentive documents prepared, fixed investments and employment correspondi ...Daha fazlası

Social network analysis of tourism data : a case study of quarantine decisions in COVID-19 pandemic”, International Journal of Information Management Data Insights

Fatma Altuntaş

Tourism is one of the most affected sector during the COVID-19 pandemic all over the world. Quarantine decisions are the leading measures taken in practice to reduce possible negative consequences of the COVID-19 pandemic. There is limited work in the literature on how to make the right quarantine decisions in a pandemic. Therefore, the aim of this study is to propose the use of social network analysis (SNA) based on tourism data to make the right quarantine decisions in the COVID-19 pandemic. A case study on quarantine decision is conducted based on data obtained from Turkish Statistical Inst ...Daha fazlası

Back to the Past: Is the West Moving from Crisis Management to Full-Spectrum Deterrence Including Nuclear Force?

Suat Dönmez

During the Cold War, the West tried to deter and contain the Soviet Union and Warsaw Pact. This deterrence was based on both conventional and nuclear forces and various concepts and doctrines. After both sides achieved an assured destruction capability, deterrence was achieved by nuclear balance. Once the Cold War ended, the focus shifted from deterrence and containment to crisis management as the international security environment became dominated by internal conflicts, international terrorism, global crime, and problems related to failed states like refugee crises. This resulted in defence c ...Daha fazlası

Battle Royale Optimizer with a New Movement Strategy

Sara Akan | Taymaz Akan

Gamed-based is a new stochastic metaheuristics optimization category that is inspired by traditional or digital game genres. Unlike SI-based algorithms, individuals do not work together with the goal of defeating other individuals and winning the game. Battle royale optimizer (BRO) is a Gamed-based metaheuristic optimization algorithm that has been recently proposed for the task of continuous problems. This paper proposes a modified BRO (M-BRO) in order to improve balance between exploration and exploitation. For this matter, an additional movement operator has been used in the movement strate ...Daha fazlası
