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
Environmental policy is shifting the focus from production processes to product-related issues. The provision and use of environmental information is generally considered an essential element in addressing the environmental impacts associated with the life cycle of products. Environmental product declarations (EPD) are one of the much promoted informative instruments. A wide range of self-declarat
Emerging wireline transmission systems such as G.fast use bands up to around 200 MHz on short cables. A key enabler for achieving the aspired throughput of several hundred Mbit/s is joint processing of transmit signals in downstream direction as well as joint processing of receive signals in upstream direction through techniques referred to as vectoring. A new challenge in such systems are sudden
