  2. 1. Towards a Road Safety Development Index (RSDI) : Development of an International Index to Measure Road Safety Performance

    Author : Ghazwan Al Haji; Kenneth Asp; Linköpings universitet; []
    Keywords : Technology; Road safety; RSDI; ASEAN; international comparisons; Human Development; Index; ranking; principal components; composite indicators; macro-performance indicators; macro-models; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Aim. This study suggests a set of methodologies to combine different indicators of road safety into a single index. The RSDI is a simple and quick composite index, which may become a significant measurement in comparing, ranking and determining road safety levels in different countries and regions worldwide.

  4. 2. Index theory in geometry and physics

    Author : Magnus C H T Goffeng; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Index theory; Cyclic cohomology; Regularized index formulas; Toeplitz operators; Pseudo-differential operators; Quantum Hall effect; Toeplitz operators;

    Abstract : This thesis contains three papers in the area of index theory and its applications in geometry and mathematical physics. These papers deal with the problems of calculating the charge deficiency on the Landau levels and that of finding explicit analytic formulas for mapping degrees of Hölder continuous mappings.

    Abstract : During recent decades, lumbar spinal stenosis (LSS) has become the most common indication for spine surgery, a change that coincides with a higher worldwide prevalence of overweight and obesity. Thus, surgical treatment of LSS in the overweight and obese population is common and increasing in scope. READ MORE

  6. 4. Road Safety Development Index : Theory, Philosophy and Practice

    Author : Ghazwan Al-Haji; Kenneth Asp; Karl-Lennart Bång; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Transport; Road Traffic; Sustainability; Road safety; European research cooperation; Civil engineering and architecture; Research on Europe; Public health science; Statistics; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Abstract : This dissertation develops, presents and tests a new international tool, the so-called Road Safety Development Index (RSDI), which indicates in a comprehensive and easy way the severity of the road safety situation in a specific country and/or in comparison with other countries. There are three pillars of outcomes involved in the framework of RSDI. READ MORE

  7. 5. Using the speech intelligibility index for evaluating speech test results and hearing aid characteristics

    Author : Lennart Magnusson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; articulation index; hearing aid; hearing loss; speech intelligibility index; speech recognition;

    Abstract : Understanding speech is crucial for human communication. Therefore, speech audiometry plays an important part in the assessment of the hearing impaired, and improved speech intelligibility is a major goal of hearing aid fitting. READ MORE
