   Sammanfattning : s the dependence of IS/IT has grown in modern organizations, IT investments have soared in the last couple of decades. Large amounts of money are spent with the hope that the investments will generate value for the business organizations using the systems. LÄS MER

3. 17. Physical characterization of coarse clasts with 3D image-analysis method : development, evaluation and application

   Författare :Solomon Tafesse; Joanne Fernlund; Mark Johnson; KTH; []
   Nyckelord :3D image analysis; Particle angularity; Sieve analysis; Particle form; Gravel analysis; Repeatability; Lithological distribution;

   Sammanfattning : This thesis presents a novel three dimensional (3D) image-analysis method for characterizing the physical characteristics of coarse particles in the field, and introduces new methodology for the total analysis of glacial till samples.The novel image analysis method, called the GID method, is capable of determining the size, shape and surface texture of each individual clast analysed.

4. 18. Economic evaluation of hypertension treatment

   Författare :Magnus Johannesson; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic evaluation; hypertension; cost-benefit analysis; cost-effectiveness analysis; the contingent valuation method; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Sammanfattning : This thesis focuses on economic evaluation of hypertension treatment.The purpose of the study was threefold: to calculate the costs ofhypertension treatment at an individual and a national level; to analyse the importance of different methodological issues for the cost-effectiveness of hypertension treatment; and to test the contingent valuation (CV) method in this field.

5. 19. Fatigue evaluation of welded details – using the finite element method

   Författare :Mustafa Aygül; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; the finite element method; welded details; effective notch stress method; Hot-spot stress method; fracture mechanics;

   Sammanfattning : The fatigue evaluation of welded details is generally based on the notion of nominal stress, using the classified S-N curves with corresponding fatigue classes for typical details. An approach of this kind should be used with extra caution to ensure that the load effects for components are accurately captured, because an ever-increasing number of welded details are resulting in a limited number of possible treatable design cases.
