Abstract This document gives example call flows of race conditions in the Session Initiation Protocol (SIP). Race conditions are inherently confusing and difficult to thwart; this document shows the best practi...

Manganites are very complex systems because of interplay among charge, spin, orbital and lattice degrees of freedom. To come closer to the understanding of its nature, we discuss its three important features: 1) correlation between magnetization and electrical resistivity in the same temperature range; 2) detection of chemical constitution and the arrangement of Mn and Mn ions at different hole...

This paper deals with the design of e-SCM for a supply chain of a commercial vehicle company. Two first vendors and two second vendors of the company are included in the objects of developing e-SCM system. We analyzed the information flow and business process between 1st vendor and 2nd vendors. The database (DB) has to be designed for contents of easy access, correction and update, because DB i...

One of the most useful properties of dynamical systems is the existence of invariant manifolds and their invariant foliations near an equilibrium or a periodic orbit. These manifolds and foliations serve as a convenient setting to describe the qualitative behavior of the local flows, and in many cases they are useful tools for technical estimates which facilitate the study of the local bifurcat...

The core purpose of software development is to provide solutions to customers' real problems. Use cases1 are a vital aspect of a technique that has been used successfully to ensure that development projects actually focus on these problems. They are used to discover, capture, and present customer requirements in a form that is accessible to developers, testers, and other stakeholders in a devel...

1 The control-flow for five kinds of use cases is analysed: for common use cases, variant use cases, component use cases, specialised use cases and for ordered use cases. The control-flow semantics of use cases – and of the uses-relation, the extends-relation and the precedesrelation between use cases is described in terms of flowgraphs. Sequence diagrams of use cases are refined to capture the...

In this paper we present concepts for and experiences with a Situated Public Display system deployed in a university setting. We identify the rate with which information is updated as an important property to distinguish different kinds of information. With a first slideshow based prototype it was very difficult for users to predict whether information was updated since they last looked. To sol...

We study, in the fluid flow framework, the cooperative dynamics of a buffered production line in which the production rate of each work-cell does depend on the content of its adjacent buffers. Such state dependent fluid queueing networks are typical for people based manufacturing systems where human operators adapt their working rates to the observed environment. We unveil a close analogy betwe...
