A Framework for Simulation of Requirements Engineering Processes

The objective of the work presented in this paper is to design and develop a framework for simulation of requirements engineering processes. The framework is intended to be a support when simulation models are built by guiding the modeler in which components to use in this type of models and to speed up the process of developing simulation models. The framework was developed through an iterative p

Inquiry and deliberation in judicial systems : The problem of jury size

We raise the question whether there is a rigorous argument favoring one jury system over another. We provide a Bayesian model of deliberating juries that allows for computer simulation for the purpose of studying the effect of jury size and required majority on the quality of jury decision making. We introduce the idea of jury value (J-value), a kind of epistemic value which takes into account the

Extending Attribute Grammars with Collection Attributes - Evaluation and Applications

Collection attributes, as defined by Boyland, can be used as a mechanism for concisely specifying cross-reference-like properties such as callee sets, subclass sets, and sets of variable uses. We have implemented collection attributes in our declarative meta programming system JastAdd, and used them for a variety of applications including devirtualization analysis, metrics, and flow analysis. We p

Living donors - How far can we proceed? A brief report on a Swedish interview study

In Sweden "anonymous living donation'' (ALD) has recently been performed but is still under evaluation. We considered it important to learn more about the thoughts of the volunteers for such a donation. Five persons out of ten people who had volunteered to donate anonymously at the transplant unit at Malmo University Hospital were interviewed. The main reason for the wish to donate was the possibi

Studying Diplomacy

This chapter singles out three areas of possible future research, where psychology in collaboration with other social science disciplines may make important contributions: (1) diplomatic signaling, (2) diplomatic culture, and (3) interaction dynamics.

Corporate Brand Positioning – Case Studies across Firm Levels and Over Time

Positioning is a key concept in the fields of branding, marketing, and strategy. In brand management, positioning deals fundamentally with finding a balance between sameness and differentiation. Empirical research predominantly examines the effectiveness of certain strategies. Less is known about the management process and internal brand positioning dynamics. Furthermore, positioning research stil

Asex and Evolution: A Very Large-Scale Overview

Asexuals come in all sorts. In this personal overview, I identify asexual organisms with eukaryotes that do not regularly go through the meiotic cycle. Such organisms may be asexual in many different ways and of many different reasons. The spread of asexuality is therefore always a unique process, and any notion of a general evolutionary advantage for asexuality is at best misleading. In discussio

Synthesis of Transition Metal Aluminides from Elemental Powder Mixtures

Popular Abstract in English Structural components such as those used in gas turbines for energy conversion applications, are subjected to high loads at elevated temperatures. In order to ensure that the components survive under these conditions for a sufficiently long time, it is imperative to select materials with good high temperature properties like strength and corrosion resistance. Such materStructural components such as those used in gas turbines for energy conversion applications, are subjected to high loads at elevated temperatures. In order to ensure that the components survive under these conditions for a sufficiently long time, it is imperative to select materials with good high temperature properties like strength and corrosion resistance. Such materials are usually alloys with

On the Effects of Nonuniform Sampling for Interferometric Phase Estimation in the Presence of Layover

Abstract in Undetermined This work tackles the problem of interferometric phase estimation in the presence of layover by using nonuniform multibaseline interferometric synthetic aperture radar systems. The effects of nonuniform sampling on Fourier-based and superresolution spectral estimation methods are investigated. The impact on both the spectral properties and on the interferometric phase esti

Vibration-induced muscle injury in the hand - experimental and clinical studies

Popular Abstract in Swedish Störningar i händernas finmotorik, kraft och känsel är vanliga symtom efter långvarigt bruk av handhållna vibrerande verktyg. I gynnsamma och lindriga fall kan dessa besvär gå tillbaka efter upphörande av expositionen för vibrationer. I mer avancerade fall tilltar besvären och ett hand-arm vibration syndrom (HAVS) utvecklas. Detta tillstånd utgör ett av de allvarligare Exposure to vibration is known to cause vasospastic white fingers and/or sensorineural symtoms such as numbness and tingling in fingers and/or musculoskeletal disorders such as reduction in muscle force, fatigue and reduced endurance. Classifications for the vasospastic and sensorineural symptoms are established. The general purpose of this thesis was to test the hypothesis that vibration exposur

Unshrouded rotor tip clearance effects in expander cycle turbines

Steady flow in axial one-stage turbines is assessed numerically and experimentally. The simulations are performed on coarse meshes using a standard numerical approach (3D, steady state, kε-turbulence model, wall function at solid boundaries). In order to allow for conclusions drawn from these rapid numerical studies, the approach was compared with an explicit LDA (Laser Doppler anemometry) mapping
