  2. 1. An rf-sputtering system and applications to amorphous zinc telluride films

    Author : Per G. Larsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis describes the fabrication and study of amorphous zinc telluride films. Their behaviour on post thermal treatments including crystallization are investigated. READ MORE

  4. 2. Multi-year maintenance optimisation for paved public roads - segment based modelling and price-directive decomposition

    Author : Per-Åke Andersson; Per Olov Lindberg; Torbjörn Larsson; Jonathan Bard; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; road maintenance optimisation; price-directive decomposition; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : I avhandlingen studeras hur kostnadseffektiva underhålls- (uh-)planer för belagd väg kan genereras, på basis av information om aktuellt vägytetillstånd och funktionella modeller för kostnads- och tillståndsförändringar, delvis utvecklade i samarbete med svenska Vägverket (VV). Tilltänkt användning är på strategisk och programnivå, innan mer detaljerad objektinformation finns att tillgå. READ MORE

  5. 3. Aktivitetsbaserad kalkylering i ett nytt ekonomisystem : en modell för ett nytt internredovisnings- och kalkylsystem med praktikfall från Gunnebo Fastening AB

    Author : Rolf G. Larsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Activity-Based Costing (ABC) for a New Management Accounting System is a report on a matrix model. The model combines traditional financial data from the accounting system with non-financial data from production, administration and marketing. The financial dimension is divided into cost centers at a foreman level. READ MORE

  6. 4. Optimization of Low-Level Controllers and High-Level Polymer Grade Changes

    Author : Per-Ola Larsson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process control; PID control; robustness; noise sensitivity; dynamic optimization; polymerization; Modelica;

    Abstract : Two design problems at different levels in the control hierarchy are considered; optimization of robust low-level controllers with constrained control signal activity and optimization of economical high-level polyethylene grade changes. As for the first design problem, a constraint on control signal activity due to measurement noise is presented and used when optimizing and comparing PI/PID controllers with measurement filters of different orders.

  7. 5. Lubricant replenishment in the vicinity of an EHD contact

    Author : Per-Olof Larsson-Kråik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Lubricants are subjected to high pressures in many mechanical devices - notably gears, cams, piston rings and rolling element bearings. The contact pressure between the ball and the race in a ball bearing can be as high as 5 GPa. READ MORE
