Universal perception and production constraints may constitute phonetic preconditions for historical sound change. It is pointed out that the traditional literature on the Swedish dialects provides a rich source of information in evaluating the diachronic role played by these constraints.
Modelling is a fairly mature technology that is already being adopted by industry. Unfortunately the tools for supporting Model-Driven Engineering are not at the same level of maturity. In particular merge tools that are an important help for collaboration lack a lot to be desired in providing the support that is needed on industrial projects. Current model merge tools and research approaches focu
The extension of businesses to incorporate the provision of function as a service in supplement to standalone products is an ongoing movement in manufacturing industry. In short, this means that the development intent should be guided by the need of ‘performance in use’ that the customer wants, e.g. thrust rather than an engine. By this, the established knowledge base challenges the development te
Specific advantages with Particle Induced X-Ray Emission are: its (1) multielemental capability, especially when combined with nuclear techniques for lighter elements, (2) speed, (3) low detection limits for small samples and (4) accuracy. To make full use of these advantages, analytical parameters have to be chosen optimally and the facility to be carefully designed. This paper describes an exper
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
The direct and inverse scattering problems for a plane-stratified viscoelastic medium excited by a transient plane wave of SH or P-SV type are treated. The viscoelastic medium is characterized by two time and space dependent memory functions and a spatially dependent density. The direct and inverse problems are solved by a time-domain wave propagator method that is related to the Green functions t
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
