An abstract argumentation framework and the semantics, often called Dungean semantics, give a general framework for nonmonotonic logics. In the last fifteen years, a great number of papers in computational argumentation adopt Dungean semantics as a fundamental principle for evaluating various kinds of defeasible consequences. Recently, many papers address problems not only with theoretical reas...

The aim of this paper is to point out some problems of index estimation for the purposes of weather derivative valuation considering the particularities of agriculture. The assessment of the sensitivity of barley to weather over 40 years has been the basis for the design and valuation of weather derivative in the Czech Republic (The Southern Moravia Region). The analysis is based on regression ...

Abstract Many frameworks exist across the sciences and science-policy interface, but it is not always clear how they are developed or can be applied. It also often vague new existing positioned in a theory of science to advance specific paradigm. This article examines these questions positions role as integral scientific tools, highlighting benefits critiques. While useful for synthesizing comm...

With the continuous maturity and development of big data technology system, deep learning has been widely used in field Industrial Internet Things. However, traditional training model with centralized is prone to leakage private information industry, such as facial information. In recent years, federated solves problem privacy caused by sharing not only contributing local models. Federated does...

We work in set-theory without choice ZF. Given a commutative field K, we consider the statement D(K): “On every non null K-vector space there exists a non-null linear form.” We investigate various statements which are equivalent to D(K) in ZF. Denoting by Z2 the two-element field, we deduce that D(Z2) implies the axiom of choice for pairs. We also deduce that D(Q) implies the axiom of choice fo...

This article argues that Nietzsche’s transvaluation project refers not to a mere inversion or negation of a set of nihilism-prone, Judeo-Christian values but, instead, to a different conception of what a value is and how it functions. Traditional values function within a standard logical framework and claim legitimacy and “bindingness” based on exogenous authority with absolute extension. Nietz...
