Looking ahead, the quest for environmental sustainability may turn out to be the most important political challenge of the twenty-first century. Though consensus is growing about some of the policy objectives like climate stability, political attitudes to these issues remain highly contested. Political parties seem to differ on both ontological assessments (how severe are the problems) and remedia

A new type of chemical reactor has been designed by Alfa Laval AB, the open plate reactor (OPR), which is a combination of a continuous reactor and a high-performance plate heat exchanger. It combines good mixing with high heat transfer capacity. In this paper we present a mid-rangingcontrol structure for the utility system that provides the open plate reactor with cooling water. The mid-ranging c

Methane is a powerful greenhouse gas and growing concern regarding global climate changes over the last years has pointed out the need to quantify and control the leaking of methane into the atmosphere. Landfill gas is regarded as one of the major sources for methane migration to the atmosphere. In this study we present research work with the objective to evaluate the use of geoelectrical resistiv

In his licentiate thesis, Calle Sjöström sums up his own and Certec's experience from almost five years' work on haptic interfaces for people with disabilities. The haptic technology tested have great potential for future development, but need refinement

Evaluation of IT investments is a difficult and complicated issue. This chapter presents a framework for control of IT investments with the aim of providing decision-makers with a clear picture of individual IT investments as well as an aggregated level where all IT investments are combined into a total picture. The framework has been developed using an action–research approach.In a number of work

Purpose 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 innovati

Agricultural intensification has led to dramatic population declines among many farmland bird species. Negative effects of intensive farming in terms of decreased local habitat quality or structural simplification of farmland landscapes have reduced both reproductive outcome and winter survival of many species. Studies investigating agricultural effects on migrating birds using farmland as stopove

Increasing soft error rates for semiconductor devices manufactured in later technologies enforces the use of fault tolerant techniques such as Roll-back Recovery with Checkpointing (RRC). However, RRC introduces time overhead that increases the completion (execution) time. For non-real-time systems, research have focused on optimizing RRC and shown that it is possible to find the optimal number of

In order to meet the demands of globalization, universities across the world are in the process of managing issues of multilingualism (Doiz et al. 2013; van der Walt 2013). In Sweden, since the passing of the Language Act in 2009, state-funded universities are obliged to use Swedish as their official language while also becoming increasingly internationalized. While the Language Act makes Swedish
