Data streams (streaming data) consist of transiently observed, evolving in time, multidimensional data sequences that challenge our computational and/or inferential capabilities. In this paper we propose user friendly approaches for robust monitoring of selected properties of unconditional and...

Due to the famous Gale-Shapley Theorem we know that each classical marriage problem admits at least one stable matching. This fact inspired researchers to search for the maximum number of possible stable matchings, which is equivalent to find the minimum number of unstable matchings, among all...

We study the process, called the IEDI process, of iterated elimination of (strictly) dominated strategies and inessential players for finite strategic games. Such elimination may reduce the size of a game considerably, for example, from a game with a large number of players to one with a few...

We study a cost allocation problem under asymmetric information, and show that the ex ante incentive compatible core is non-empty. We also obtain a non-emptiness result for the incentive compatible coarse core, which is one concept of an interim core.

This paper presents a method for evaluating the risks in a situation where parameters in the calculation are expressed in the form of dependent fuzzy numbers and probability distributions. The procedure of risk estimation combines stochastic simulation with the execution of arithmetic operations...

This paper investigates a supply chain system in which a single manufacturer procures raw materials from a single supplier, processes them to produce finished products and then delivers the products to a single-retailer. The customer’s demand rate is assumed to be time-sensitive in nature...

This paper models the situation where the attacker’s resources are unknown to the defender. Protecting assets presupposes that the defender has some information on the attacker’s resource capabilities. An attacker targets one of two assets. The attacker’s resources and...

This paper focuses on the implications of market frictions in the context of serial correlations in indexes on the Central and Eastern European (CEE) stock markets. Market frictions, such as non-trading effects, bid/ask spreads, other transaction costs, etc., may be detected by direct...

Our concern in this paper is to present a different perspective from the more ‘traditional’ approaches to studying solutions of games in partition function form. We provide a decomposition of the space of such games under the action of the symmetric group, for the cases with three...

This paper presents a new formulation of (approach to) threat analysis and management of security understood in a wide sense. Threats have been analyzed in a wide theoretical-methodological spectrum. Particular emphasis is put on the need for the system-wide analysis of threats, especially...
