Västerås slott : Slott och borgar
- 2000
-
Reports (pop. science, debate, etc.)abstract
- En majoritet av dagens byggnadsuppgifter gäller att hantera det redan byggda. När vi står inför situationen att restaurera en befintlig byggnad är det viktigt att förstå olika tidsperioders stilideal liksom byggnadsteknik och material. Först då kan vi göra en väl avvägd analys, som tar tillvara och utvecklar de kvaliteter som byggnaderna själva besitter. Därför är utbildningen upplagd som ett växelspel mellan föreläsningar, seminarier, exkursioner och en för året vald studieuppgift.Slott och borgar har varit läsårets tema. Vi har valt att arbeta med Västerås och Örebro slott - två ganska bortglömda Vasaslott som är väl värda att lyfta fram. Särskilt har vi studerat de senaste 300 årens förändringar, som inte tidigare ägnats lika stora forskarmöda som medelitden och Vasatiden. I dessa två exempel finns en provkarta på estetiska, praktiska och tekniska ingrepp från Carl Hårlemans tid och fram till idag.Studierna har således omfattat både gestaltning, funktion och byggnadsteknik. Avsikten är att visa på kvaliteter i de omvandlingar och restaureringar som skett, men också att peka på problem och analysera olika möjligheter inför framtiden. Arbetet har skett i samarbete med Statens fastighetsverk och är tänkt att utgöra ett underlag till vårdprogram och framtida restaureringsinsatser.

Characteristics of elderly people readmitted to the hospital during the first year after stroke. The Göteborg 70+ stroke study.
- 2002

Journal article (peer-reviewed)abstract
- BACKGROUND AND PURPOSE: Readmissions after acute stroke vary over time and with age and comorbidity. Knowledge of the reasons for readmissions and characteristics of readmitted patients is sparse. This 1-year prospective study examined whether readmissions were related to severity of the index stroke or to comorbidity and explored outcomes in readmitted patients with respect to daily life activities and health-related quality of life. METHODS: The study included 216 elderly patients (aged >/=70 years) discharged to their homes or a nursing home after index stroke. The main outcomes were readmission rates and reported diagnoses, performance of daily life activities and health-related quality of life. RESULTS: Nearly half (45%) of the patients were readmitted to the hospital after being discharged to their homes. One readmission was most common, and stroke-related diagnoses were most frequently reported as the reason for readmission. Different forms of heart disease were the next most common reason. The readmitted patients were significantly more dependent in daily life activities, and health-related quality of life was significantly lower among this group. CONCLUSIONS: Recurrent stroke and sequelae after stroke were major factors behind readmissions, followed by heart disease in elderly stroke patients. The readmitted patients were more dependent in daily life activities and reported a lower health-related quality of life compared with not readmitted patients.

Use and cost of assistive technology the first year after stroke. A randomized controlled trial.
- 2002
-
In: International Journal of Technology Assessment in Health Care. - 0266-4623. ; 18:3, s. 520-7
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: The objective was to compare and evaluate assistive technology given to patients treated in a stroke unit and patients treated in a general medical ward. METHOD: Use and cost of assistive technology was evaluated in a randomized study comprising 249 patients during a 12-month period. RESULT: Acute stroke unit care was associated with a higher prescription of assistive devices during the first 3 months. There was no difference in use and total mean cost per patient of assistive technology during the first year after stroke. CONCLUSION: There was no difference in use or cost of assistive technology during the first year, but a beneficial effect was found on supplementary prescription of assistive devices during the first 3 months. The cost during the first year after stroke was a small fraction of the total costs for care and rehabilitation. It is not expensive for the community to equip these patients and their caregivers with assistive technology, and economic resources should be available to this vulnerable group of elderly patients.

A Large-scale Testbed for Reproducible Ad hoc Protocol Evaluations
- 2002

Conference paper (peer-reviewed)abstract
- We have built an ad hoc protocol evaluation testbed (APE) in order to perform large-scale, reproducible experiments. APE aims at assessing several different routing protocols in a real-world environment instead of by simulation. We present the APE testbed architecture and report on initial experiments with up to 37 physical nodes that show the reproducibility and scalability of our approach. Several scenario scripts have been written that include strict choreographic instructions to the testers who walk around with ORiNOCO equipped laptops. We introduce a mobility metric called virtual mobility that we use to compare different test runs. This metric is based on the measured signal quality instead of the geometric distance between nodes, hence it reflects how a routing protocol actually perceives the network's dynamics.

Coping with Communication Gray Zones in IEEE 802.11b based Ad hoc Networks

-
Reports (other academic/artistic)abstract
- Our experiments with IEEE 802.11b based wireless ad hoc networks show that neighbor sensing with broadcast messages introduces “communication gray zones”: in such zones data messages cannot be exchanged although the HELLO messages indicate neighbor reachability. This leads to a systematic mismatch between the route state and the real world connectivity, resulting in disruptive behavior for some ad hoc routing protocols. Concentrating on AODV we explore this issue and evaluate three different techniques to overcome the gray zone problem. We present quantitative measurements of these improvements and discuss the consequences for ad hoc routing protocols and their implementations.
