Job strain and major risk factors for coronary heart disease. : Baseline results from the WOLF Study

- The results do not support the hypothesis that job strain has an adverse impact on serum total cholesterol and plasma fibrinogen levels. They suggest that an increased risk of coronary heart disease in association with job strain, if causal, is mediated by other factors, possibly partly by hypertension and low levels of high-density lipoprotein cholesterol.

The development and performance of a grammar checker for Swedish : A language engineering perspective
- 2004

Ingår i: Natural Language Engineering. - 1351-3249 .- 1469-8110. ; 1:1

Tidskriftsartikel (refereegranskat)abstract
- This article describes the construction and performance of Granska – a surface-oriented system for grammar checking of Swedish text. With the use of carefully constructed error detection rules, written in a new structured rule language, the system can detect and suggest corrections for a number of grammatical errors in Swedish texts. In this article, we specifically focus on how erroneously split compounds and disagreement are handled in the rules. The system combines probabilistic and rule-based methods to achieve high efficiency and robustness. The error detection rules are optimized using statistics of part-of-speech bigrams and words in a way that each rule needs to be checked as seldom as possible. We have found that the Granska system with higher efficiency can achieve the same or better results than systems with conventional technology.

Automated generation of representations in vision

- This paper presents a general strategy for automated generation of efficient representations in vision. The approach is highly task oriented and what constitutes the relevant information is defined by a set of examples. The examples are pairs of situations that are dependent through the chosen feature but are otherwise independent. Particularly important concepts in the work are mutual information and canonical correlation. How visual operators and representations can be generated from examples are presented for a number of features, e.g. local orientation, disparity and motion. Interesting similarities to biological vision functions are observed. The results clearly demonstrates the potential of combining advanced filtering techniques and learning strategies based on canonical correlation analysis (CCA).

Folkliga möbler : tradition och egenart : en stilanalytisk studie av renässans- och barockdrag i den svenska folkliga möbelkonsten
- 2001
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- A collection of furniture, most of which was produced before 1770, forms the basis of this description and explanation of the characteristics distinguishing vernacular furniture from bourgeois furniture, and the vernacular furniture in one area from that in another. The vernacular material is used to test the convincing force of the art history terms created to describe the artistic expression of the upper-class culture. The criteria previously used to define the specific characteristics of vernacular furniture is called into question and modulated.The study shows how regional characteristics can be observed as early as in the seventeenth century in many areas, long before what is considered the most prosperous period of vernacular art. It shows how Renaissance features played a crucial part in influencing the inherited characteristics of vernacular furniture right up until the emergence of rococo features in vernacular painting, towards the end of the eighteenth century, and sometimes even longer.The study focuses on the selection of stylistic features as an active choice. The survival of Renaissance features at the expense of baroque features cannot only be attributed to retardataire or 'cultural fixation' as a consequence of economic stagnation and lack of outside influence. The choice of certain stylistic features over others depends on a number of reasons. The pews, pulpits and other features in the parish churches that served as models played a crucial part. Out of all of that, the village joiner would chose the models he considered best suited for domestic furniture, and disregarded the others.

Människor och kvarts : sociala och teknologiska strategier under mesolitikum i östra Mellansverige
- 2004
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis deals with the social dimension in lithic technology during the Mesoltihic in eastern central Sweden. The starting point is the empirical observation of the disappearing bipolar-on-anvil method of reduction around 4500 BC. This method of reduction is often used on quartz and it is the dominant method of reduction at Stone Age sites dated to the period before 4500 BC. It subsequently almost disappears without any sign of technological innovation at the time. Several other changes in the Mesolithic society occur at this time; the large aggregation sites disappear and contact with other areas changes. All this points to that the technological change is only one indication of more profound changes in the organisation and structuring of the society at this time. By looking at technology as a practice, it can be related to the social communications and negotiations that occur between different people. Tool making is seen as an arena where people of different gender and age are engaged. Lithic technology has a strong performative character that is an important part in the constant communications of social identities. This performative character is expressed at the knapping floors. The knapping floors are analyzed spatially and with a fracture analysis. The method of fracture analysis is developed as a result of experimental knapping. The result of the analysis of knapping floors from seven Mesolithic sites indicate that there is a contradiction between on the one hand organizing tool production in different strategies, as a result of different social groups being engaged in the making of quartz tools, and on the other hand, the spatially structuration of knapping floors where all stone working is located in one place. This contradiction is seen as an example of the duality of action and structure. By spatially organising the knapping floors as places where people met, they were given a purpose as a levelling device in an egalitarian structure. The disappearance of the bipolar-on-anvil method of reduction around 4500 BC is only a small symbol of more profound changes in the social structure in the Mesolithic society, changes in the way people percieved their world and themselves.

Issues on filter networks for efficient convolution
- 2004

Ingår i: Proceedings of the Swedish Symposium on Image Analysis (2004). - Uppsala. ; , s. 94-97

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper presents the new project Efficient Convolution Operators for Image Processing of Volumes and Volume Sequences . The project is carried out in collaboration with Context Vision AB.By using sequential filtering on 3D and 4D data, the number of nonzero filter coefficients for a desired filter set can be significantly reduced. A sequential convolution structure in combination with a convolver designed for sparse filters is a powerful tool for filtering of multidimensional signals.The project mainly concerns the design of filter networks, that approximate a desired filter set, while keeping the computational load as low as possible. This is clearly an optimization problem, but it can be formulated in several different ways due to the complexity.The project is in an initial state and the paper focuses on experiences from prior work and discuss possible approaches for the future progress.
