Unsplittable max-min demand allocation - a routing problem

The end-to-end assignment of bandwidth to node-pairs (demands) in a communication network can be considered fair if it is distributed according to the max-min fair (MMF) principle. This paper investigates the problem of obtaining an MMF allocation if each demand is required to use exactly one path (i.e., to use unsplittable flows). First it is shown that the problem is NP-hard, both if each demand

The Dynamic Relation Between IS Integration and the Merger and Acquisition Process

Corporate mergers and acquisitions (M&A) have established themselves as prominent tools for corporate strategy. Consequently more and more organizations direct their attention towards the potential benefits of an M&A and the problems of leveraging these potentials. Managing information systems (IS) integration in M&A means understanding the dynamic relationship between IS integration a

Public participation in the 3G infrastructure development in Sweden

The infrastructure for 3G has been under development in Sweden since late 2000. Following from the so called beauty contest four operators within three years were to build competing systems to cover 99,98 percent of the population by the end of 2003, giving the administrative system an extreme challenge. Issues widely debated has been the alleged hazardousness of the electromagnetic radiation from

Overload Protection for CORBA Systems with Time Constraints

Scalable and reliable distributed object-oriented computing (DOC) middleware systems is an important technology in, for example, telecommunications service logic and distributed web servers. The Common Object Request Broker Architecture (CORBA), developed by the Object Management Group (OMG) is a speci cation of a common platform for DOC systems. CORBA acts as middleware, by inserting itself betwe

The cotton-top tamarin carries an extended semenogelin I gene but no semenogelin II gene

Previous studies have shown that the predominant proteins secreted by the seminal vesicles are transglutaminase substrates which have undergone major structural alterations during evolution. In man, they are known as semenogelin I and II; recently it was shown that, similar to man, several new world and old world monkeys carry two semenogelin genes as well, the exception being the cotton-top tamar
