Recent results have shown that denoising an image with the Rudin, Osher and Fatemi (ROF) total variation model can be accomplished by solving a series of binary optimization problems. We observe that this fact can be used in the other direction. The procedure is applied to the two-phase, piecewise constant Mumford-Shah functional, where an image is approximated with a function taking only two valu
Many of you have certainly heard about the ISA S95 standard, and you know that it treats the subject of how Enterprise/business systems such as e.g., SAP, Baan, Movex etc should be integrated with manufacturing and control systems You might also be aware that of B2MML (Business to Manufacturing Markup Language), a set of XML schemas corresponding to the S95 object models. B2MML is intended to be u
Issue management in market-driven software projects is constantly under time pressure. A limited set of developers must share their time between developing features for the next release and resolving reported issues. Project managers need to find the appropriate balance between a high quality product and fast time to market. We study a telecom company in Sweden developing embedded systems for a co
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
Popular Abstract in Swedish Vanlig bagerijäst, Saccharomyces cerevisiae, används i storskalig etanol framställning från majs och sockerrör. Användandet av dessa råvaror för etanolproduktion konkurerar dock med framställning av spannmål för föda och djurhushållning. Den här avhandlingen har syftat till att få bagerijäst att använda sockerarten xylos, som finns i stora halter i restprodukter från skBaker’s yeast, Saccharomyces cerevisae, has been engineered to utilize the pentose sugar xylose present in lignocellulose biomass for the production of ethanol. Currently ethanol production from xylose is slow which limits the implementation of said strains in industrial production. This thesis describes the investigation of several metabolic aspects that control the rate of xylose utilization by
There is a need from industry to better understand how customers perceive products. To develop products without understanding subjective perceptions and experiences is to risk that products with low customer value are devel-oped. As a consequence product target groups may be missed and intended market success may not occur. Traditional approaches for capturing subjective customer experiences are
