Polyploid evolution in the European orchid genus Nigritella: evidence from DNA fingerprinting

The genus Nigritella (Orchidaceae-Orchidinae) is a complex of species at four different ploidy levels. Fourteen taxa at species or subspecies level have been distinguished. The triploid N. nigra ssp. nigra is endemic to Scandinavia, whereas the remaining taxa are confined to different mountain regions in Central and Southern Europe. The polyploids are of hybrid origin and have arisen from taxa at

A Scala Embedded DSL for Combinatorial Optimization in Software Requirements Engineering

The goal of the presented work is to provide support for software requirements engineering domain experts in modeling combinatorial optimization problems that arise in requirements prioritization and release planning. A Domain-Specific Language (DSL), called reqT/CSP, is presented that integrates constraints modeling with requirements modeling. The DSL is embedded in the object-functional Scala pr

Simulation of Physical Disabilities in Computer Designs of Environments

This paper presents some methods of improving the simulation of human movements. Since we are developing a tool for the planning of environments for physically disabled persons, it is important to consider the future user’s abilities in particular. Methods such as the use of human models, acquiring joint ranges and motions (from MacReflex and DataGlove systems), editing postures and motions, setti

Pooling and emergency replenishment policies in inventory systems

This thesis deals with two types of problems occurring in inventory theory; pooling of stock and perishable items. All three papers in this thesis consider inventory distribution systems with continuous review. In Paper I we consider a single-echelon inventory system with two identical locations. Demands are generated by stationary and independent Poisson processes. In this paper, we allow later

Efficient and Transparent use of Computational Mechanics Software on Clusters and GRID:s

To further the use of cluster and GRID resource, it is important to provide the user with a user friendly environment, providing command line utilities, graphical user interfaces and web access. This paper describes the tools developed for use at cluster at the Center for Technical and Scienti c Computing at Lund University, Lunarc.

Nonequilibrium and many body effects in the realistic simulation of intersubband emitters

This study gives a short description of nonequilibrium and many body effects in realistic simulation of intersubband emitters. Calculations are based on the self-consistent solution of the quantum kinetic equations under operating steady-state conditions. Scattering with phonons is included by means of a self-energy in the Dyson equation, and electron-electron interaction is treated in mean field
