Characterization of low-dimensional semiconductor structures is a challenging task. The thesis is based on experiments, using cathodoluminescence (CL) as a tool for characterization. The high spatial resolution and the possibility of spectroscopy of small structures make CL one of the most powerful techniques for these types of investigations. QDs were fabricated of InP on GaInP and InAs on GaAs b

There is nothing such as a standard person and a product will always exist in a context. It is of democratic importance to be able to take part in society on an equal level. Non-discriminating design tries to meet the diversity among users when new design solutions are created. Although functionality will remain an es-sential precondition for user satisfaction with products and market success, emo

This thesis deals with tools for operational improvement of supply chain performance. The work was aimed at providing knowledge for supply chain developers and practitioners, and identifying and developing tools for improved performance in a supply chain. The investigation was part of a project financed by the European Commission called "Industrial Supply Chain Optimizer" (ISCO). The thesis consis

I Sverige finns ett stort bostadsbestånd som står inför ombyggnad. Miljonprogrammets bostäder är över 40 år gamla och behöver rustas upp. Det är angeläget att denna upprustning utformas på ett sådant sätt att husen byggs om till energieffektiva byggnader med låga framtida drifts- och uppvärmningskostnader och med låg miljöpåverkan under hela livscykeln. Det är i sammanhanget viktigt att energieffe

This article is a continuation of my article in Working Papers 45, 1996, which was an analysis of definite marking and referential status of nouns. This article is a parallel and deals with verbs, namely aspect marking and situation types, and has the same approach, cognitive and typological, and the same corpus: an extract from a Swedish children’s book. After a presentation of the theoretical ba

A study of Swedish post-war amateur and experimental film culture, and especially the gradual divide between amateurs and experimentalists.

This paper presents a new industrial adaptive PID controller. The controller has the PID structure, with dual rate sampling, which means that the sampling rate for the PID controller is significantly higher than the sampling rate in the parameter estimator. The controller differs from conventional parametric adaptive controllers because it is based on estimation of transfer function properties. Fo
