Self-Tuning Controllers Based on Pole-Zero Placement

The paper gives a review of pole-placement design for systems with known parameters, then focuses entirely on the servos. Adaptive pole-placement algorithms are discussed, leading to the formulation of explicit and implicit schemes, and simulation of the behaviour of the alorithms is given.

Gemenskap i mytens spegel: prinsessan Europa och hennes bror Kadmos i eftervärldens ögon

The article surveys the Medieval and Early Modern reception of two ancient Greek myths: the stories about the Phoenician princess Europe and her brother Kadmos. During the 12th - 17th century the interpretation of pagan myths flourished in Europe, justified by allegorical exegesis. The myths of Europe and Kadmos were viewed as disguised teachings containing historical, moral or religious truth. Fo

Transcriptional Analysis of Cell-Sorted B-cell Lymphomas From High-throughput to Focused Identification of Molecular Targets

B cell lymphomas (BCLs) are a group of severe cancers, afflicting both men and women at different ages. Gene expression profiling (GEP), have during the latest decades fundamentally contributed to a better classification and biological understanding of the different BCLs. Most studies using GEP have analyzed mRNA from tumor tissue constituted of both tumor cells and non-malignant bystander cells.

Nitric oxide synthase in female reproductive and urinary organs: Hormonal regulation and functional significance

Popular Abstract in Swedish Nobelpriset i fysiologi och medicin 1998 gick till tre forskare från USA som gjort forskningsinsatser för upptäckten av kväveoxid (NO) vilket är en viktig signalsubstans i våra kroppar. Upptäckten av att en så liten molekyl som NO har så många funktioner i kroppen anses som en av de mest överraskande i medicinhistorien. Redan 1876 började man använda nitroglycerin som eNitric oxide synthase (NOS) activity was studied in cytosolic and particulate fractions in reproductive organs from rabbit (uterus and vagina) and rat (uterus, vagina and cervix). NOS was found predominantly in cytosolic fractions in all tissues and the activity of NOS in both fractions was highly Ca2+ dependent. NOS activity in vagina and cervix were much higher (3-6-fold) than in the uterus. Est
