  2. 21. On improvement of cast iron brake discs for heavy vehicles

    Author : Gael le Gigan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brake disc; cast iron; hot spots; cracking; elevated temperatures; material modelling; finite element analysis; drag braking; material testing; rig experiment; fatigue assessment;

    Abstract : Disc brakes are commonly used in motorcycles, passenger cars, commercial vehicles, heavy-duty vehicles, passenger trains and landing gears of airplanes. Depending on the application, a wide variety of brake discs have been developed, with a multitude of designs, geometries and materials. READ MORE

  4. 22. Alkylglucosides - physical chemical properties

    Author : Frederik Nilsson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; penetration experiment; DSC; SAXS; NMR self-diffusion; phase separation; size micro-structure; aggregate-aggregate interaction; liquid crystalline phases; micelles; alkylglucosides; phase diagrams; fluorescence.; Physical chemistry; Fysikalisk kemi;

    Abstract : The aim of this study is to characterise the physical-chemical properties of alkylglucosides. Alkylglucosides are non-ionic surfactants synthesized from glucose and a fatty alcohol. The glucose molecule constitutes the hydrophilic head group and the fatty alcohol constitutes the hydrophobic tail. READ MORE

  5. 23. High-Speed Vision and Force Feedback for Motion-Controlled Industrial Manipulators

    Author : Tomas Olsson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Force vision control; Visual tracking; Visual servoing; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : Over the last decades, both force sensors and cameras have emerged as useful sensors for different applications in robotics. This thesis considers a number of dynamic visual tracking and control problems, as well as the integration of these techniques with contact force control. READ MORE

  6. 24. Essays on Microeconometrics and Immigrant Assimilation

    Author : Alpaslan Akay; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Average marginal effect; Marginal effect of the average individual; Employment and earnings assimilation; Quasi-fixed effects approach; Initial value problem; Dynamic censored random-effects model; Monte Carlo experiment; Heckman’s approximation; Simple method of Wooldridge; Dynamic random-effects sample-selection model; wage-curve method;

    Abstract : Paper I. Asymptotic bias reduction for a conditional marginal effects estimator in sam- ple selection models. In this article we discuss the di¤erences between the average marginal effect and the mar- ginal effect of the average individual in sample selection models, estimated by the Heck- man procedure.

  7. 25. Hyperbaric oxygen treatment for pelvic radiation-induced injuries. From a multicenter randomized controlled trial to an experimental cell model

    Author : Nicklas Oscarsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hyperbaric oxygen treatment; hyperbaric oxygen; late radiation-induced injury; cystitis; proctitis; reactive oxygen species; radiation therapy; quality of life;

    Abstract : Introduction Cancer is affecting a growing number of persons. Still, the treatment and survival of cancer is improving. Radiation therapy is used in the treatment of cancer. Late radiation-induced injuries afflict 5–15% of irradiated patients. READ MORE
