Concrete itself is not a source of VOC emissions of any importance. However, humid concrete is very alkaline and may cause degradation of organic materials. Concrete can also adsorb considerable amounts of volatile compounds, e.g. from degrading flooring materials. This together with the present trends in cement and concrete production (alternative fuels, new organic additives, waste materials) ha

Syftet med detta utkast är att analysera hur ungdomar som varit placerade på särskilda ungdomshem upplever, definierar och tolkar ett behandlingsprojekt, som involverade olika myndigheter, benämnt Motverka Våld och Gäng. Dessutom uppmärksammas hur de tolkade de i projektet anställda samordnarna. Den personliga aspekten i relationen mellan ungdomar och samordnare framställs som viktig och det verk

Purpose To explore what theoretical lenses have been used to analyze and understand information sharing in supply chains. We elaborate on the predominant theories and discuss how they can be used to research different aspects of information sharing. Design/methodology/approach We carried out a structured literature review by using a combination of selected keywords to search for peer-reviewed art

The increased popularity of and attention for innovation based regional growth and development has, among other things, brought forward the importance of universities in regional innovation systems (RIS). The triple helix literature especially underscores the value of increased interaction and interdependence between universities – industry – government in modern, knowledge-based economies by accl

Today almost every system or service, e.g., water, power supply, transportation, etc. is dependent on IT systems, and failure of these systems have serious and negative effects on the society. IT incidents are critical for the society as they can stop the function of critical systems and services. Moreover, in a software engineering context risk analysis is an important activity for the developmen

We study the joint design of optimal linear MIMO encoders and decoders for filtering and transmission of a vector- valued signal over parallel Gaussian channels subject to a real- time constraint. The objective is to minimize the sum of the estimation error variances at the receiving end. The design problem is nonconvex, but it is shown that a global optimum can be found by solving a related two-s

This paper presents a case study evaluating a retrospective analysis method, aimed at improving the release planning activity in project management. The method is based on a re-evaluation of candidate requirements for prior releases in order to uncover release planning decisions that would have been made differently today. The method aims at using the lessons learned during the analysis to find im

We calculate the phase property of the reflection coefficient in two-terminal structures using a lattice tight-binding model. It is seen that, provided that there exist two coherent reflection paths, the reflection probability can be zero for certain electron energies. At these energies, the phase of the reflection coefficient shift abruptly by $pi$. Next, we study the reflection and transmissio
