Argumentation is a reasoning model based on the construction and the evaluation of arguments. In his seminal paper, Dung has proposed the most abstract argumentation framework. In that framework, arguments are assumed to have the same strength. This assumption is unfortunately strong and often unsatisfied. Consequently, three extensions of the framework have been proposed in the literature. The...

The structural framework for a parametric catchment erosion model is proposed. A parameter optimization technique that provides a rational basis for the calibration of the model is developed. The adequacy of the model in representing a natural catchment is investigated.

The Multidimensional Scale of Irrational Beliefs (MSIB) is a brief and theoretically founded measure of irrational thinking as conceptualized by Albert Ellis in his most recent works on Rational Emotive Behavior Therapy (e.g., Ellis, 2003). With a total of 18 items, it captures demandingness, negative self-evaluation, and low frustration tolerance as the three core aspects of irrationality. Unl...

in this paper, the factors affecting the attitude of youth toward immigration have been examined, using a survey method and questionnaire. the sample under study consisted of 892 young people from shiraz. the theoretical framework of the research was based on the theories of giddens, bayen, izen, and lee’s theory of immigration and the experimental method of research was designed based on their...

In this paper, we examine the relationship between volatilities of energy index, crude oil, gas prices, and financial assets (Gold, Bitcoin, G7 stock indexes), especially during coronavirus crisis. The study tests presence regime changes in GARCH volatility dynamics indexes, Gold, (energy gas) by using Markov–Switching model. It estimates dynamic correlation spillover assets, multivariate MSGAR...

We propose a new Conditional BEKK matrix-F (CBF) model for the time-varying realized covariance (RCOV) matrices. This CBF is capable of capturing heavy-tailed RCOV, which an important stylized fact but could not be handled adequately by Wishart-based models. To further mimic long memory feature special with conditional heterogeneous autoregressive (HAR) structure introduced. Moreover, we give s...

Die neue Oberflächenregistrierungsmethode mittels Gauß-Feldern (GF) wurde zur Automatisierung des Patientenregistrierungsverfahrens in der navigierten HNO Chirurgie entwickelt und validiert. Die Methode formuliert eine Gaußsche Energiefunktion (GEF) als die Summe der euklidischen Punktabstände, die durch Gewichtungsfaktoren multipliziert werden, um die Reliefbesonderheiten der zu registrierende...
