The paper presents a feedback scheduling strategy for multiple control tasks that uses feedback from the plant states to distribute the computing resources optimally among the tasks. Linear-quadratic controllers are analyzed, and expressions relating the expected cost to the sampling period and the plant state are derived and used for on-line sample-rate adjustments. In the case of minimum-varianc

Att utforma och använda mål för att styra har vuxit fram som en stor styrfråga. Om inte en ständig listetta i kommuner och landsting de kommande åren, talar mycket åtminstone för en tio i topp placering på lednings- och styrvertygslistan. Så har det alltid varit menar en del av er. Och visst har ni rätt i det. Men har det någonsin varit så här mycket? Är det inte ovanligt mycket trummor och trumpe

Popular Abstract in Swedish Denna avhandling beskriver den centrala metabolismen och produktionen av exopolysackarider (EPS) hos två olika mjölksyrabakterier: Lactobacillus reuteri och Pediococcus parvulus. Mjölksyrabakterier används inom livsmedelsindustrin som startkulturer i olika mjölkbaserade produkter. Generellt utnyttjas en specifik metabol väg för nerbrytningen av sockerkällan till mjölksyThis thesis deals with the central carbohydrate metabolism and exopolysaccharide (EPS) formation in two different lactic acid bacteria (LAB): Lactobacillus reuteri and Pediococcus parvulus. LAB are traditionally used as starter cultures in the food industry. In general, LAB harbours one glycolytic pathway converting carbohydrates into lactic acid. However, L. reuteri ATCC 55730 was proven to use t

Neoplastic disorders are characterized by recurrent somatically acquired chromosomal aberrations that alter the structure and/or expression of a large number of genes. Most “cancer genes” discovered to date in human neoplasms have been identified through isolation of genes at the breakpoints of balanced chromosomal translocations. Although functional studies of such cancer-causing genes have demon

In order to explore the attitudes of physicians in hospital mergers, a survey was distributed to the Southern Sweden University Hospital (in Swedish Skånes universitetssjukhus). The merger was implemented January 1, 2010, and the survey was distributed November 8, 2011. Twelve clinics were selected for the study and the response rate was 54 per cent (355 out of 663 physicians). This paper reports

The chapter deals with the ungoing movement of the Van Gujjar nomads in India and their struggle for identity as one of the indigenous people of the country.

This is the final report of the project “Ascending evacuation in long stairways: Physical exertion, walking speed and behaviour”. This project investigated the effects of fatigue on walking speeds, physiological performance and behaviours in case of long ascending evacuation. The report includes a literature review on, at the time when the project began, existing material on ascending evacuation o

Under 1880-talet utkristalliserades en ny kvinnoroll. Yrkeskvinnan började konkurrera med husmodern. Sedligehtsdebatten i mitten av 1880-talet blev en kamp mellan olika syn på sedlighet, kvinnor och män. Sexualiteten var i fokus, och olika aspekter av denna diskuteras i anknytning till kvinnors framflyttade positioner, exempelvis som författare. Sophie Elkan och Selma Lagerlöf framträder så smånin

Angle resolved photoelectron spectroscopy has been performed on the valence band of NiO at the National Swedish Laboratory for Synchrotron Radiation. Normal emission spectra have been recorded for photon energies between 17 and 140 eV in order to study the electronic structure of the valence band. The experimentally determined band structure has been compared with a local density augmented plane w

The idea of the 'Swedish model' has been a widespread and enduring concept in the social sciences since the 1930s, associated with the political dominance of the Social Democratic Party, peaceful social development and a tradition of political consensus. Taking this exceptionalism as their starting point, the essays in this volume present new research on Swedish political movements of the nineteen

Emerging wireless sensor and actuator network (WSAN) technology has the potential to enable semi-autonomous air-flow control to improve the aerodynamic performance of aircraft. In this paper, a WSAN topology comprising of multiple linear sensor clusters terminated by actuators is proposed for active flow control. Two interference aware convergecast scheduling strategies are presented and analyzed,
