  1. 6. Aircraft Trajectory Optimization with Tactical Constraints

    Författare :Martin Norsell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; trajectory optimization; radar cross section; stealth; radar range constraints; network centric warfare; tactical constraints; multidisciplinary optimization;

    Sammanfattning : Aircrafttrajectory optimization is traditionally used forminimizing fuel consumption or time when going from one flightstate to another. This thesis presents a possible approach toincorporate tactical constraints in aircraft trajectoryoptimization. The stealth technology of today focuses on making thetactics already in use more effective. LÄS MER

  3. 7. Issues in Urban Travel Demand Modelling : ICT Implications and Trip timing choice

    Författare :Maria Börjesson; Staffan Algers; Kay Axhausen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Journey; Mathematical model; Origin traffic ; Time; Telecommuting; Journey time; Variability; Stated preference; Delay; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; 11 Road: Personal transport; 11 Road: Personal transport;

    Sammanfattning : Travel demand forecasting is essential for many decisions, such as infrastructure investments and policy measures. Traditionally travel demand modelling has considered trip frequency, mode, destination and route choice. This thesis considers two other choice dimensions, hypothesised to have implications for travel demand forecasting. LÄS MER

  4. 8. Set Constraints for Local Search

    Författare :Magnus Ågren; Pierre Flener; Justin Pearson; Gilles Pesant; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; combinatorial problems; constraint-based local search; constraint-directed search; constraint programming; incremental algorithms; monadic existential second-order logic; neighbourhoods; penalty; set variables; set constraints; variable conflicts; Computer science; Datavetenskap; Datavetenskap; Computer Science;

    Sammanfattning : Combinatorial problems are ubiquitous in our society and solving such problems efficiently is often crucial. One technique for solving combinatorial problems is constraint-based local search. Its compositional nature together with its efficiency on large problem instances have made this technique particularly attractive. LÄS MER

  5. 9. Ta plats eller få plats? : Studier av marginaliserade människors förändrade vardagsliv

    Författare :Cecilia Kjellman; Institutionen för kulturgeografi och ekonomisk geografi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Intellectually disabled; Drug addicts; Constraints; Projects; Health; Daily life; Marginalised groups; Social geography; Time geography; Sence of place; Socialgeografi;

    Sammanfattning : The aim is to study and analyse processes intended to change the daily lives of two marginalised groups and enable them to participate to a greater extent in the community. The two marginalised groups are young male drug addicts and older intellectually disabled. LÄS MER

  7. 10. Återbesök i Eskilstuna : En undersökning av morfologisk variation och förändring i nutida talspråk

    Författare :Eva Sundgren; Lars-Gunnar Andersson; Bengt Nordberg; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Scandinavian languages - general; Sociolinguistic variation; language change; spoken Swedish; Eskilstuna; morphology; real time; apparent time; panel study; trend study; individual change; generational change; intralinguistic constraints; salience; quantitative analysis; implicational scaling; local integration; social mobility; Nordiska språk - allmänt; Scandinavian languages; Nordiska språk; nordiska språk; Scandinavian Languages; Languages and linguistics;

    Sammanfattning : Real-time replications of empirical studies of language use are scarce. This study of language change in real time replicates an investigation of the social variation of spoken Swedish in the medium-sized town of Eskilstuna, using data collected 29 years after the original study.
