Numerical Solution to H∞ Control of Multi-Delayed Systems via Operator Approach

A computational algorithm for the full information H∞ control problem for multi-delayed LTI systems is derived. The algorithm is based on a general operator approach in the spectral domain developed for finite-dimensional LTI plants. The simplicity of spectral operations and explicit formulas for computation make it possible to generalize it to infinite-dimensional plants. In the paper, a complete

Effects of dietary fibre on the human metabolism and metabolome

Popular Abstract in Swedish Kostfiber visar på gynnsamma effekter på blodsockersvar, inflammationsmarkörer och blodfetter utifrån tre humanstudier som genomfördes i detta arbete. I en av studierna analyserades blod och urin med metabolomik. Det är en metod där man analyserar alla små molekyler (metaboliter) som finns i provet med hjälp av vätskekromatografi kopplat till masspektrometri. Med hjälp It is well-known that dietary fibre can have a positive effect on the development of lifestyle-dependent diseases such as cardiovascular disease and type 2 diabetes. However, the effect may be different for different kinds of fibre and different sub-populations at risk. Therefore, the effects of three different kinds of fibre on postprandial and long-term response in healthy subjects were investig

Tracing local hyaluronan after ocular anterior segment trauma

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Hyaluronan (hyaluronsyra) är en högmolekylär polysackarid som förekommer i all biologisk vävnad i olika koncentrationer, med särskilt höga nivåer i bindväv. Den kan bildas av de flesta celltyper. På molekylär nivå föreligger den i form av ett nystan, har förmågan att binda stora mängder vatten, och har en uttalad pseudoplasticitet. HyaHyaluronan has been found in the eye in varying amounts and at different sites. It is involved in physiological and pathological processes, though many aspects of its bio-logi-cal functions are still unclear. We have studied the role of iris tissue in hyal-uro-nan production in the anterior segment of the eye, and its changes after trauma. After peripheral iridectomy or argon laser treatment, the

Long-term follow-up after otitis media in childhood

Popular Abstract in Swedish Bakgrund: Öroninflammation är vanligt förekommande i barnaåren. De flesta barn har haft minst en episod med akut varig öroninflammation (AOM) och/eller en period med vätska i mellanörat (SOM) före skolstart. De flesta får enstaka episoder, frekvensen av AOM avtar i 2-års åldern och frekvensen av SOM avtar före skolstart. Efter en AOM episod är det vanligt att man under Objective: Most preschool children have suffered from at least one episode of acute otitis media (AOM) and/or secretory otitis media (SOM). Some children have frequent AOM episodes and/or prolonged and recurrent episodes of secretory otitis media (SOM). The long-term out-come and sequelae are not fully clarified. Subjects and methods: Out of a birth cohort followed to the age of 3 years, 12 child

Ergonomic Evaluation of Two Different Locations of the Scales in a Supermarket Checkout System

The aim of this pilot study was to ergonomically evaluate the effect of the location of the scales in a supermarket checkout system. A location of the scales to the left of the cashier was compared with a location under the conveyor belt. Two cashiers were videotaped while working with the two scale locations, in both sitting and standing working postures. Analysis of the video tapes was performed

Cooperative multi-provider eouting optimization and income distribution

We consider the problem of cooperative distributed routing optimization in multi-domain/multi-provider networks. The main object of our investigation are ASON/G-MPLS transport networks, still the results of our investigations could be extended to any multi-domain network where particular domains have limited mutual visibility of intra-domain resources. This paper refines a distributed decompositio

Nordens Medelhav. Östersjöområdet som historia, myt och projekt

The book is a general history of the Baltic Sea region, written from a dual historical perspective. The first is genetic, focusing on the development of the region, on periods of intense contacts and communications between the peoples and states bordering the Baltic Sea, and on period in which the sea was a dividing and closed area. The second historical perspectice is genealogical, focusing on ho
