Background. Traditional crash-based analysis of road safety at individual sites has its shortcomings due to low numbers and the random nature of crashes at individual sites and the related statistical issues, as well as the under-reporting of crashes and lack of information on contributing factors and the process preceding crashes. To get around the problem, road safety analysis based on surrogateAbstract Background.

A very simple and extremely computationally efficient algorithm for blind separation of two speech sources from two mixtures is presented in this paper. The algorithm exploits the approximate W-disjoint orthogonality of speech signals and assumes specific sensors (microphones) setting that allows the sources to possess a feature we call cross high-low diversity. Two sources are said to be cross hi

The main purpose of this study is to provide marketers with basic guidelines on how brands can benefit from internet social networks such as MySpace, Facebook and Hi5.

Syftet med studien var att undersöka sambandet mellan självrapporterad sömn och källminne. Detta undersöktes med hjälp av en modifierad version av Johansson och Stenbergs (2002) svenska Deese-Roediger-McDermott (DRM) test. Frågeställningarna som undersöktes var (1) Orsakar DRM testet semantiska sammanblandningar (att deltagarna tenderar att svara "gammalt" på lurord)? (2) Finns det ett s

The aim of this paper is to provide insights into, and perspectives on, the transformation of mindsets for logisticians. We argue that by exploring paradoxes inherent in the efficiency-focused paradigm of today, a strategic mindset can emerge in which central logistics management issues can be addressed, understood, and dealt with in order to enhance supply chain effectiveness and innovation. Base

Improved energy efficiency in the housing stock is an important undertaking in the energy transition but is associated with both opportunities and risks. While there are possibilities to reduce energy inequalities in the housing stock, inequalities also risk being aggravated as actions for energy efficiency usually aim at the least energy efficient—and thus sometimes the least privileged—parts of

Spatial planning of Blue-Green Infrastructure (BGI) should ideally be based on well-evaluated and context specific solutions. One important obstacle to reach this goal relates to adequate provisioning of data to ensure good governance of BGI, i.e., appropriate planning, design, construction, and maintenance. This study explores the gap between data availability and implementation of BGI in urban p
