  1. 1. Type Ia Supernovae : Homogeneity and Diversity

    Författare :Gabriele Garavini; Ariel Goobar; David Branch; Stockholms universitet; []
    Nyckelord :Physics;

    Sammanfattning : The use of type Ia supernovae as distance estimators has shown that about 75% of the energy content of the universe has a negative equation of state parameter and thus, drives the acceleration of the universe. Constraining the exact nature of this energy is one of the main goals in cosmology. LÄS MER

  3. 2. Testing Homogeneity and Unit Root Restrictions in Panels

    Författare :Johan Blomquist; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Non-stationary panels; Panel unit root tests; Cross-sectional dependence; Homogeneity testing;

    Sammanfattning : This thesis is divided into two distinct parts. The first part contains three chapters, co-authored with Joakim Westerlund, that deal with the analysis of unit root testing, and the second part consists of two chapters on slope homogeneity testing. LÄS MER

  4. 3. Det följdriktiga flockbeteendet: : en studie om profilering på arbetsmarknaden

    Författare :Ann Erlandsson; Torbjörn Bredenlöw; Andreas Werr; Växjö universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; employer branding; labor market; homogeneity; heterogeneity; social identity; reputation; recruitment.; Business studies; Företagsekonomi;

    Sammanfattning : Despite ample research showing the importance of corporate reputation in recruiting, knowledge about how companies work with employer branding is still limited. This first academic study in this topic is based on a comprehensive empirical data set systematized to a description of employer branding using a grounded theory approach. LÄS MER

  7. 5. An Experimental Study of Liquid Steel Sampling

    Författare :Ola Ericsson; Pär Jönsson; Andrey Karasev; Malin Hallberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; liquid steel sampling; slag protection; filling velocity; solidification rate; sample homogeneity; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Sammanfattning : Sampling of liquid steel to control the steel making process is very important in the steel industry. However, there are numerous types of disposable samplers and no united standard for sampling. The goal in this study is to investigate the effect of slag protection type and sample geometry on sampling parameters and sample homogeneity. LÄS MER
