In today’s highly competitive market place it is of great importance for companies to deliver reliable products while decreasing the development time and costs. The time to market is a driving force for many companies, and throughout the engineering design process as well as the manufacturing process, the focus is on finding timesaving actions. However, the search for timesaving actions will most

Isotropic chiral media can be modeled in several ways. We show that when realizing such a medium from spiral inclusions with real permittivities and permeabilities in a periodic structure, a modified Drude-Born-Fedorov model is obtained. This model equals the original Born model for small wave vectors, but the strength of the chirality depends on the propagation direction. The effective parameters

This paper reports on some preliminary results from the first stage of an interview survey, focusing on current practices and challenges in market-driven RE. The interviews are analysed based on the characteristics of market-driven RE presented in the literature. The interviews correspond largely with the literature. Identified discrepancies compared with the literature concerns the time-to-market

Disturbances on utilities, such as steam and cooling water, often cause large revenue losses at industrial sites. These disturbances are often hard to handle, since they commonly are plant-wide disturbances that affect more than one production area at the site. Also, the production areas of the site are often dependent on other production areas because of the flow of product through the site, whic

A number of techniques have been proposed to provide run- time performance guarantees while minimizing power consumption. One drawback of existing approaches is that they work only on a fixed set of components (or actuators) that must be specified at design time. If new components become available, these management systems must be redesigned and reimplemented. In this paper, we propose PTRADE, a n

The benefits of integrating a real-time oriented language for description of control algorithms, PAL, into a package for computer aided control system design, SIMART, are investigated. An anti-wind-up partial state model reference controller, designed and validated in this environment, has been successfully tested in real-time on a double tank system.

This study investigated the effect of confirmatory and disconfirmatory feedback on the accuracy (realism) in witnesses’ confidence judgements of their event memory. After watching a short video of a kidnapping the participants answered 44 two-alternative questions on the videotape. Two weeks later the participants were handed their old question-answering sheet with the original questions and their

This thesis describes the development of a temperature control system for optical spectroscopy experiments with rare-earth doped samples. Low temperature emission spectra were afterwards recorded for a series for Eu3+ singly doped and Ce3+, Eu3+ codoped Y2SiO5 samples. The analysis and assignment of the different energy transitions is presented. The experimental setups used in this thesis involve

Humans have always communicated with each other. When the smartphone technology was launched on the market, it revolutionized the way people communicate. This smartphone technology is constantly evolving and during 2014 wearable computing seems to be in the focal point at most smartphone technology conferences. This master thesis aims to discover how a wearable computing device can further develo
