Nonlinear Feedforward and Reference Systems for Adaptive Flight Control

Use of feedforward can alleviate feedback and adaptive actions. Feedforward signals can be generated from reference models and the same models can also be used as reference models in adaptive control. A method for designing the reference models is presented in the paper. By exploiting the structure of the equations describing air vehicles it is possible to find reference models that scale to the p

Packaging design in organic food supply chains – a case study in Sweden

Packaging design is vital in the consumer product industry. This is why the recent consumer preferences for locally produced and organic food need to be met by product and package producers in the packaging design process. The purpose of this study is to understand how packaging design is managed in food supply chains with a special focus on organic and locally produced food in Sweden. It also ide

Numerical methods for load prediction in acoustic fatigue

Acoustic fatigue can occur in structural elements of an aircraft exposed to very high sound pressures. To deal with acoustic fatigue, mainly empirical methods have been applied and often late in the design phase. Current design guidelines have several limitations. First, they do not say anything about the load intensities. The load levels can be determined either experimentally or numerically. Exp

Språkövergång : rapport från ett studiebesök på Teaterhögskolan i Oslo (februari 2005)

Jag har sedan länge haft ett stort intresse för att låta skådespelarelever få undervisning inte bara i så kallad rikssvenska utan jag anser att de även bör få lära sig att använda olika dialekter i sitt sceniska arbete. Ett intresse för detta finns också hos elever. Många skådespelare menar att undervisning i andra dialekter skulle vara nyttigt. Man har bl.a. påpekat att det skulle medföra en ökad
