    • BACKGROUND: There is a need for a short and easily administered scale, in the Swedish language, for assessing partner relationships in the health care of persons with cardiac disease. PURPOSE: To establish the reliability and validity of the Swedish version of the Relationship Assessment Scale (RAS). DESIGN: The present pilot study has a methodological design. FINDINGS: Content validity has been tested for relevance, clarity and readability. The scale was tested for construct validity with explorative factor analysis. The reliability was tested by internal consistency and test-retest analysis. The result showed a two-factor solution, which does not correspond to the original proposed one-factor solution. The factor analyses revealed two quite distinct factors of RAS, labelled "Relationship built on expectations and satisfaction of needs" and "Relationship built on love and devotion". CONCLUSIONS: The scale has satisfactory psychometric properties in terms of content validity, construct validity, homogeneity and stability in a population of persons with cardiac disease. Wider evaluations of the RAS for other populations and settings are recommended.

  • Measuring and using the RSSI of IEEE 802.11p
  • 2010
  • Ingår i: 17th World Congress on Intelligent Transport Systems, ITS 2010, Busan, South Korea, 25-29 October 2010.
  • Konferensbidrag (refereegranskat)abstract
    • The scalability of intelligent transport systems (ITS) applications is difficult to test in a field operational test (FOT) due to the high number of ITS equipped vehicles required. Therefore, computer simulations for evaluating different wireless communication technologies for ITS different applications can serve as a complement. In this paper we present results from lab measurements conducted on the CVIS hardware platform equipped with the upcoming standard IEEE 802.11p. We have measured the packet error rate versus the signal-to-noise ratio (SNR) for different packet lengths. This lab measurement is the first step towards an outdoor measurement campaign which also considers interference. The outdoor measurements will then be fed into a computer simulator together with a realistic channel model for evaluating the scalability of VANETs in a highway scenario.
