Handheld computing and mobile information systems are continuously breaking new ground, with an increased importance for business. However, there is evidence that we still have lessons to learn concerning the design of handheld information systems. Handheld information system poses challenges to the designer in the unique properties of handheld technologies and the conditions of use of handheld te
Popular Abstract in Swedish I Big Bang skapades 3 grundämnen: H, He, och spår av Li. Alla andra grundämnen har bildats i stjärnor. Lågmassiva stjärnor som vår sol kan genom kärnreaktioner skapa grundämnen upp till och med syre i det periodiska systemet, medan mer massiva stjärnor kan skapa grundämnen ända upp till järn. Tyngre grundämnen än järn produceras in slutstadierna av stjärnornas liv, tillAll the elements heavier than Li are created during stellar evolution. Even if our knowledge of this process is good, many questions still remain. For instance, the odd-Z iron-peak elements Sc, V, Mn, and Co together with neutron-capture elements Sr, Zr, La, Ce, Nd, Sm, and Eu have still unclear production sites because theoretical models and observational evidences are not in agreement. Having a
Popular Abstract in Swedish Robotar är maskiner som rör sig efter hur man programmerar dem. I industriellt bruk monteras ofta ett verktyg på roboten så att den kan svetsa, gripa, slipa, borra eller göra andra saker. Det som gör roboten bra på detta är att den kan upprepa robot-programmet flera gånger när det har blivit skrivet. Detta gör att man kan programmera roboten en gång för en arbetsuppgiftAdvanced manufacturing technologies and programmable machines such as industrial robots are used to increase productivity and quality for competitiveness on a global market. Development of increasingly flexible manufacturing systems has resulted in an increasing importance of software aspects, both on a system level and for efficient interaction with human operators. Trends toward providing custom
The human side of mergers and acquisitions (M&A) – with focus particularly on resistance - has puzzled scholars for decades. Still, there is little discussion as regards to how the concept should be defined or understood. Often expressions of resistance, rather than its actual content, are described. What do personnel actually oppose? In this dissertation, the content, process, and context of
Popular Abstract in Swedish I och med att mjukvarubaserade produkter ökar i antal ökar också vikten av en effektiv mjukvaruutvecklingsprocess, ur ett konkurrensperspektiv. Bristfällig produktkvalitet och höga utvecklingskostnader är något som mjukvaruutvecklingsorganisationer under många år har kämpat med. Studier inom SPI (software process improvement) syftar till att förbättra produktkvalitet ocThe number of software-based products is increasing, which is why the importance of an efficient software development process is also increasing, from a competitive advantage perspective. For years, software development organizations have been plagued by poor product quality and high development costs. Studies in software process improvement (SPI) have concerned themselves with improving the softw
As the contribution of dispersed or distributed energy resources (DER) to the electric power production increases, the effects on the power system grow more important. As an example a critical situation may arise if protective relays trip a large part of the dispersed generation due to undervoltage at a short-circuit event. On the other hand it is crucial that the protection system acts correctly
Transport of people and freight on-road have a big impact on the total energy use in the world. The majority of these transports is propelled with diesel engines and the reason is simply that the diesel engine is better than the gasoline engine due to lower fuel consumption. But the cost of this is the increase in dangerous nitrogen oxides (NOx). Around 10 000 people dies everyyear due to emission
In response to the challenge of socializing new IT employees, some IT departments are exploring the incorporation of enterprise social media (hereinafter ESM) as an informal organizational socialization tool. Because this is a relatively new phenomenon, little is known about how ESM facilitate employee socialization. In order to contribute to our understanding of how ESM affects employee socializa
The article explores the degree to which memory studies has become established as an academic field. Although we acknowledge that there are drawbacks to formal institutionalization, we contend that it is useful to think strategically about the future of memory studies. We argue that three key developments must take place in order for a field to become institutionalized. First, individual scholars
Adaptive and multi-level governance is often called for in order to improve the management of complex issues such as the provision of natural resources and ecosystem services. In this case study, we analyse the contemporary multi-level governance system that manages water resources and its ecosystem services in a fresh water lake in Sweden. We assess the relative importance and barriers of three c
The most critical question for climate research is no longer about the problem, but about how to facilitate the transformative changes necessary to avoid catastrophic climate-induced change. Addressing this question, however, will require massive upscaling of research that can rapidly enhance learning about transformations. Ten essentials for guiding action-oriented transformation and energy resea
Information about a building's spaces is of interest in every stage of the construction and facility management processes. An organisation1 or enterprise is located in and uses the building's spaces, and many of the building's spatial properties are determined on the basis of the user organisation's requirements. The definition of the concept "space" as applied in information systems for building Information about a building's spaces is of interest in every stage of the construction and facility management processes.

The preseni paper provides an overview of existing approaches for design and assessment of offshore structures and on this basis proposes a framework for the risk based assessment and monitoring of the performance of offshore wind energy converters in operation. In recognition of the fact that there are presently no established best practices for the assessment and monitoring of offshore wind ener
This paper describes and analyzes the strategies and efforts of a public organization in order to establish organizational credibility in multicultural areas. The trust-building efforts by the organization, a local rescue services in the south of Sweden, are a response to several years of social unrest, communicative clashes and hostile treatment between operative firemen and residents in areas of
Coordinated Multi Point (CoMP) transmission and reception techniques are used in order to improve the performance of single or multiple cells in wireless systems. A system using CoMP techniques is capable of jointly optimizing its transmission and/or reception and, hence, achieving higher performance. In this work, performance evaluation of three CoMP techniques are performed based on simulations
Coastal waters have strong gradients in dissolved organic matter (DOM) quantity and characteristics, originating from terrestrial inputs and autochthonous production. Enclosed seas with high freshwater input therefore experience high DOM concentrations and gradients from freshwater sources to more saline waters. The brackish Baltic Sea experiences such salinity gradients from east to west and from
The EC Directive 2013/59/Euratom states in article 56 that exposures of target volumes in nuclear medicine treatments shall be individually planned and their delivery appropriately verified. The Directive also mentions that medical physics experts should always be appropriately involved in those treatments. Although it is obvious that, in nuclear medicine practice, every nuclear medicine physician
A model for calculating the noise in nonlinear optical processes arising from (nonquantum) stochastic fluctuations (mode beating) in and between the lasers participating in the nonlinear interaction has been previously developed. Assuming that all individual laser mode phases and laser modes are (statistically) independent (Gaussian statistics) and that the nonlinear interaction can be expressed a
The dynamics of ethanol production/consumption in baker's yeast were studied under feed- rate controlled conditions. The yeast was grown on molasses in an 8-l fed-batch reactor and experiments were done at cell concentrations between 5 and 65 g l−1. Small changes in the feed rate were made around a feed rate corresponding to the critical growth rate, at which the yeast cell metabolism switches bet
