- The PHENIX detector is designed to perform a broad study of A-A, p-A, and p-p collisions to investigate nuclear matter under extreme conditions. A wide variety of probes, sensitive to all timescales, are used to study systematic variations with species and energy as well as to measure the spin structure of the nucleon. Designing for the needs of the heavy-ion and polarized-proton programs has produced a detector with unparalleled capabilities. PHENIX measures electron and muon pairs, photons, and hadrons with excellent energy and momentum resolution. The detector consists of a large number of subsystems that are discussed in other papers in this volume. The overall design parameters of the detector are presented. (C) 2002 Elsevier Science B.V.

- OBJECTIVES: To evaluate the health-related quality of life (HRQL) of patients with head and neck cancer during and after treatment with radiotherapy, surgery, and chemotherapy. STUDY DESIGN: Prospective, descriptive study. METHODS: All new patients in four institutions in Norway and Sweden were asked to participate. Health-related quality of life was assessed at baseline and at 1, 2, 3, 6, and 12 months after start of treatment by means of the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire and the EORTC head and neck cancer-specific questionnaire. Baseline results are described elsewhere; longitudinal results are presented in the current article. Three hundred fifty-seven patients with cancer in the oral cavity, pharynx, larynx, nose, sinuses, and salivary glands and neck node metastases from unknown primaries filled in the questionnaires at baseline. RESULTS: Seventy-eight percent of the patients who were alive after 12 months filled in all questionnaires (218/280). The general trend was that HRQL deteriorated significantly during treatment, followed by a slow recovery until the 12-month follow-up with few exceptions (senses, dry mouth, and sexuality). Patients who later died reported worse HRQL at each assessment point compared with patients who filled in all six questionnaires, whereas those who dropped out of the study for other reasons were quite similar to patients who filled in all questionnaires. The patients with pharyngeal cancer in general reported worse HRQL compared with the other groups and did not reach pretreatment values in several domains. Stage was also an important factor for HRQL in patients with head and neck cancer. CONCLUSION: Detailed knowledge about the differences between groups and changes over time may aid us in the communication with patients and in the design of intervention studies focusing on improvement of the support and rehabilitation of patients with head and neck cancer.

Target cascading in vehicle redesign : A class VI truck study
- 2002

Ingår i: International Journal of Vehicle Design. - 0143-3369 .- 1741-5314. ; 29:3, s. 199-225

Tidskriftsartikel (refereegranskat)abstract
- The analytical target cascading process is applied to the redesign of a U.S. class VI truck. Necessary simulation and analysis models for predicting vehicle dynamics, powertrain, and suspension behaviour are developed. Vehicle design targets that include improved fuel economy, ride quality, driveability, and performance metrics are translated into system design specifications, and a consistent final design is obtained. Trade-offs between conflicting targets are identified. The study illustrates how the analytical target cascading process can reduce vehicle design cycle time while ensuring physical prototype matching, and how costly design iterations late in the development process can be avoided

Simulation-based optimal design of heavy trucks by model-based decomposition : An extensive analytical target cascading case study
- 2004

Tidskriftsartikel (refereegranskat)abstract
- We present the findings of an extensive case study for the decomposed, simulation-based, optimal design of an advanced technology heavy truck by means of analytical target cascading. The use of a series hybridelectric propulsion system, in-hub motors, and variable height suspensions is considered with the intention of improving both commercial and military design attributes according to a dual-use philosophy. Emphasis is given to fuel economy, ride, and mobility characteristics. The latter are predicted by appropriately developed analytical and simulation models. This article builds on previous work and focuses on recent efforts to refine the applied methodologies and draw final conclusions.

Late quaternary ice sheet history of northern Eurasia

Forskningsöversikt (refereegranskat)abstract
- The maximum limits of the Eurasian ice sheets during four glaciations have been reconstructed: (1) the Late Saalian (> 140 ka), (2) the Early Weichselian (100-80 ka), (3) the Middle Weichselian (60-50 ka) and (4) the Late Weichselian (25-15 ka). The reconstructed ice limits are based on satellite data and aerial photographs combined with geological field investigations in Russia and Siberia, and with marine seismic- and sediment core data. The Barents-Kara Ice Sheet got progressively smaller during each glaciation, whereas the dimensions of the Scandinavian Ice Sheet increased. During the last Ice Age the Barents-Kara Ice Sheet attained its maximum size as early as 90-80,000 years ago when the ice front reached far onto the continent. A regrowth of the ice sheets occurred during the early Middle Weichselian, culminating about 60-50,000 years ago. During the Late Weichselian the Barents-Kara Ice Sheet did not reach the mainland east of the Kanin Peninsula, with the exception of the NW fringe of Taimyr. A numerical ice-sheet model, forced by global sea level and solar changes, was run through the full Weichselian glacial cycle. The modeling results are roughly compatible with the geological record of ice growth, but the model underpredicts the glaciations in the Eurasian Arctic during the Early and Middle Weichselian. One reason for this is that the climate in the Eurasian Arctic was not as dry then as during the Late Weichselian glacial maximum.
