  1. 11. Automated Bottleneck Analysis of Production Systems : Increasing the applicability of simulation-based multi-objective optimization for bottleneck analysis within industry

    Författare :Jacob Bernedixen; Amos H. C. Ng; Anna Syberfeldt; Kalyanmoy Deb; Leif Pehrsson; Magnus Wiktorsson; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; bottleneck analysis; bottleneck identification; bottleneck improvement; multi-objective optimization; simulation; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Sammanfattning : Manufacturing companies constantly need to explore new management strategies and new methods to increase the efficiency of their production systems and retain their competitiveness. It is of paramount importance to develop new bottleneck analysis methods that can identify the factors that impede the overall performance of their productionsystems so that the optimal improvement actions can be performed.

  3. 12. The role of practical work in physics education in Lao PDR

    Författare :Thongloon Vilaythong; Sune Pettersson; Oleg Popov; Bertil Sundqvist; Ogawa Masakata; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cultural-Historical Activity Theory; laboratory work; Laos; pendulum experiment; physics curriculum; physics education research; practical activities; Subject didactics; Ämnesdidaktik; didactics of physics; fysikdidaktik;

    Sammanfattning : The aim of this thesis is to get a better understanding of the role of practical work in physics education in the Lao People’s Democratic Republic (Lao PDR). The Lao PDR is one of least developed countries in the world with a weak base for science, and poor market opportunities for science graduates. LÄS MER

  4. 13. Persuasiveness in the discourse of wine : The rhetoric of Robert Parker

    Författare :Charlotte Hommerberg; Carita Paradis; Maria Lindgren; Geoff Thompson; Linnéuniversitetet; []
    Nyckelord :appraisal; assessment; critical discourse analysis; evaluation; persuasiveness; pragma-dialectics; recommendation; rhetoric; rhetorical argumentation; Robert Parker; text analysis; wine review; winespeak; Engelska med språkvetenskaplig inriktning; English;

    Sammanfattning : The primary purpose of this study is to explore a case of remarkably powerful contemporary rhetoric, namely Robert Parker’s wine writing, which has had an unprecedented impact in the world of prestigious wine for more than two decades. Parker, an American autodidact who gave up his career in law to become a fulltime wine critic, is considered the most influential critic of all time. LÄS MER
