In [4, 13], Bancilhon and Paredaens introduced a notion of completeness for relational database languages on instance-level. Their criterion was subsequently called BP-completeness. Since then, it was used frequently in the context of other database models. However, its application in the context of languages involving object creation appears to raise some serious problems. In this paper, we us...
As opposed to contemporary activity-centric, process-aware information systems (PAIS), for which a multitude of concepts and implementations exist, there is only a very limited number of PAIS implementing data-centric, artifact-centric or object-aware approaches. This demo paper presents the implementation of a modeling environment for the object-aware approach to business process management. O...
From a sample of about 10 φ mesons produced at DAΦNE, we have selected KL mesons tagged by observing KS → ππ decays. We present results on the major KL branching ratios, including those of the semileptonic decays needed for the determination of |Vus|. These branching ratio measurements are fully inclusive with respect to final-state radiation. The KL lifetime has also been measured.
This paper investigates the structure of qualitative capacities, which are monotonic increasing set functions ranging on a finite totally ordered scale equipped with an orderreversing map. More specifically, we study whether these qualitative set-functions can be viewed as classes of more particular set functions, namely possibility measures, paralleling the situation of quantitative capacities...
An uncapacitated facility location problem considers a set of n warehouses W and a set of m stores S. Each warehouse w has a fixed cost fw, and the transportation cost from warehouse w to store s is given by cws. The problem is to find a subset of warehouses and an assignment of warehouses to stores in order to minimize the fixed and transportation costs. Observe that once the warehouses are se...
In physics, a phase transition from liquid to solid means that molecules are stuck between their neighbours. We investigate a similar effect in a crowd at a small exit. People cross the exit one by one, but the majority moves very slowly. Those from behind press, and if the density is large enough, it is impossible to move with respect to our neighbours. Can one withdraw from the crowd or he/sh...
We study the influence of the dimension of cellular automata (CA) for real time language recognition of one-dimensional languages with parallel input. Specifically, we focus on the question of determining whether every language that can be recognized in real time on a 2-dimensional CA working on the Moore neighborhood can also be recognized in real time by a 1-dimensional CA working on the stan...
Network decontamination (or disinfection) is a widely studied problem in distributed computing. Network sites are assumed to be contaminated (e.g., by a virus) and a team of agents is deployed to decontaminate the whole network. In the vast literature a variety of assumptions are made on the power of the agents, which can typically communicate, exchange information, remember the past, etc. In t...
the parallel systems are special important types of coherent structures and have many applications in various areas.in this paper we consider a two-exchangeable-component parallel system for the generalized farlie-gumbel-morgenstern (generalized fgm) distribution. we study the reliability properties of the residual lifetime of the system under the condition that both components of the system ar...
A new urbanism theory has emerged in recent decades in response to numerous urban problems of the twentieth century, with the goal of creating vibrant, compact, diverse and desirable cities in terms of work, walking, life, and transportation options. In view of the widespread acceptance of this theory among the Iranian researchers, the aim of this study is to assess the sustainability of organi...
