Priority Setting in QFD - Improvements and Implications
- 1999
-
Konferensbidrag (refereegranskat)abstract
- One of the more important purposes of QFD is to prioritize customer needs and thus know where to focus resources in the future. The standard procedure in QFD is to ask customers to state their importances and there are many disadvantages connected to this procedure. The state-of-the-art approach in customer satisfaction modeling is to derive importances from the customers' evaluation of a product. This paper compares the two approaches. The conclusion is that it is better to derive the importances since it can be expected to generate more reliable results and it is easier to interpret

On-the-job training for process operators as a strategy for competence achievement - A case study
- 1996

Konferensbidrag (refereegranskat)abstract
- The technical development in complex and highly automated production processes affects the process operator’s work and the demands on the operator. Two significant problems are difficulties in acquiring and maintaining the necessary competence and a risk of understimulation, since a stable process does not generate many active tasks, largely because of a higher degree of automation. In this case study, we were able to make a comparison between an approach to job design for solving these problems and a design of two existing operator jobs. The results suggest that this approach might be effective in practice.

The Benefit of Using High-Performance Concrete for Prefabrication.
- 1998

Konferensbidrag (refereegranskat)abstract
- This article outlines a numerical study on the benefit of using High-Performance/Strength Concrete for fabrication of concrete elements. For this purpose a comparison is done between the cost of existing beams with normal strength concrete and optimized beams made of High-Performance/Strength Concrete. A background is given concerning the most essential properties of High-Performance/Strength Concrete such as strength, creep, shrinkage, carbonation and fire resistance. The results indicate that it is necessary to improve the structural configuration of the beams to fit with 16-mm strand in order to achieve an economical outfit. The direct cost reduction after optimization of the section was 15%. Also other advantages such as about 35% reduction of the required amount of carbon dioxide in order to produce cement for the same type of beam, lower cost of transport, and a decreased dead weight of the structure compared with the use of normal strength concrete motivates High-Performance/Strength Concrete for these types of structures.

Fullerenes under pressure : Structure, order, and disorder
- 1996
-
Ingår i: High Pressure Science and Technology. - Singapore : World Scientific. - 9810225474 ; , s. 697-701
-
Konferensbidrag (refereegranskat)abstract
- The weak intermolecular interactions in solid C60 and other fullerenes make crystal structures and other properties very sensitive to applied pressure. We review recent results on the properties and phases of fullerenes under pressure, concentrating on the low-p range up to about 1 GPa. Subjects discussed include compression and transport studies, orientational and rotational disorder, the glassy crystal transition, and pressure-induced polymerization.

Orientational disorder and the p-T phase diagram of fullerenes

Konferensbidrag (refereegranskat)abstract
- The translational and orientational structures of fullerenes are very sensitive to pressure, p, because of the weak intermolecular potentials. We have recently carried out high-p studies of the thermal conductivity lambda and the bulk modulus B of C60 and C70, and we show here how the p-T phase diagrams of these materials can be mapped from data for B and lambda and a knowledge of the structures at zero pressure. We discuss how B and lambda are modified by translational, rotational and orientational disorder in the materials, mainly showing examples related to the orientational substructure and its evolution with T and p in C60. We also discuss briefly the structures and phase diagrams of C70 and C61H2, and we show preliminary experimental results suggesting that the structure of high-p, high-T treated C60 is probably not polymeric as recently suggested by several groups.
