  1. 1. Final Approach : Measurements and Ratings of Aircraft Landing Noise

    Författare :Anders Johansson; Karl Bolin; Susann Boij; Antonio Filippone; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aircraft noise; acoustic measurements; psycho acoustics measurements; noise annoyance; Flygplansbuller; akustiska mätningar; psykoakustiska mätningar; bullerstörning; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Följande avregleringen av flygmarknaden har flygtrafiken ökat snabbt sedan mitten av 1990-talet. Detta har oundvikligen lett till en utbyggnad av flygplatser, vilket på många platser runt om i världen har lett till oro och konflikter på grund av ökade bullernivåer. LÄS MER

  3. 2. Modeling adsorption of organic compounds on activated carbon : a multivariate approach

    Författare :Jufang Wu; Anders Cedergren; Ingrid Fängmark; Ola Claesson; Lars-Gunnar Hammarström; Fritz Stoeckli; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; activated carbon; adsorption; adsorption capacity; adsorption rate; PCA; PLS; binary mixtures; Dubinin-Radushkevich; Wheeler-Jonas; Analytisk kemi; Analytical chemistry; Analytisk kemi; analytisk kemi; Analytical Chemistry;

    Sammanfattning : Activated carbon is an adsorbent that is commonly used for removing organic contaminants from air due to its abundant pores and large internal surface area. This thesis is concerned with the static adsorption capacity and adsorption kinetics for single and binary organic compounds on different types of activated carbon. LÄS MER

  4. 3. Mesoscopic superconductivity : quasiclassical approach

    Författare :Marek Ožana; Andrei Shelankov; Dierk Rainer; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mesoscopic superconductivity; quasiclassical theory; boundary conditions; multi-layer structures; Gor kov equations; quasiclassical Green s function; Green s function on classical trajectories;

    Sammanfattning : This Thesis is concerned with the quasiclassical theory of meso-scopic superconductivity. The aim of the Thesis is to introduce the boundary conditions for a quasiclassical Green’s function on partially transparent interfaces in mesoscopic superconducting structures and to analyze the range of applicability of the quasiclassical theory.

  5. 4. From Cost Accounting to Customer Accounting in the HospitalityIndustry : a Constructive Approach

    Författare :Mats Carlbäck; Sweden Göteborg Handelshögskolan Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Restaurant Industry; Management Accounting Tools; Management Control; Experience Accounting; FAMM; Cost Allocation; Performance Measurement; Constructive Approach;

    Sammanfattning :  The objective of this research project is to analyse and identify the role of tools used in the restaurant industry to improve resource management efficiency and performance, to develop and test the Experience Accounting tool, and to test and evaluate if this particular system is the system that could fill a gap in the hospitality industry.The research is based on the notion that the hospitality business is part of the experience industry and is producing experiences rather than a plate of food and a bed to sleep in.

  7. 5. Understanding management accounting when "institutions matter" : a multimethod approach

    Författare :Malin Härström; Jonas Gerdin; Hans Englund; Kirsi-Mari Kallio; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Management accounting; institutional theory; performance measurement; academia; situations; perceived control exposure; multimethod approach;

    Sammanfattning : This thesis departs from a need to map extant research on management accounting (MA) drawing on institutional theorizing, due to unnecessary confusion and unclarity within. Four ‘areas of confusion’ are reviewed, i.e. MA as a concept, modelling of workings of and reasons for agency, MA’s role in social accounts and sources of (i. LÄS MER
