Daylight Harvesting Control Systems: Design recommendations based on a literature review

In indoor spaces, lighting control systems are highly effective to reduce electric lighting use. Daylight harvesting systems (DHS) promise to deliver the greatest energy savings. This article presents a review about DHS based on recent scientific and technical literature. The review shows that the energy saving potential of DHS lies between 20-60% in comparison with non-dimmed installations. Howev

Effective Charges Near 56Ni and Production of Anti-Nuclei Studied with Heavy-Ion Reactions

Popular Abstract in Swedish I denna avhandling diskuteras olika aspekter av kärnreaktioner inducerade med tunga atomkärnor. En beskrivning av de experiment, detektorer och metoder som har använts återfinns tillsammans med en utförlig redogörelse av analysarbetet. De resultat som presenteras är baserade på dels experimentella data men även från simuleringar och teoretiska beräkningar. AvhandlingenThis thesis presents the research performed within two different research groups using heavy-ion induced nuclear reactions. They offer the opportunity to investigate different properties of nuclear matter. The results are based on measurements using a variety of different experimental techniques. The PHENIX experiment measured the production of deuteron and anti-deuterons at mid-rapidity in gold-

Bidding Rings: A Bargaining Approach

We address the issue of bidder ring formation in single and multi-unit Vickrey auctions. We address this issue in a bargaining game set up under the assumption that valuation of bidders is commonly known only amongst themselves. In the single unit case, we show that the equilibrium coalition structure can only be an order preserving r-ring, that includes the winner and the top (r-1) losers. In the

Projectile fragmentation of Sn-112 at Elab = 1 A GeV

We have measured production cross sections of projectilelike fragments in the reaction of neutron-deficient 112Sn with a 9Be target at an energy of Elab=1A GeV. Results have been obtained for neutron-deficient products along the N=Z line down to the subnanobarn range. We find very good agreement with the recently revised empirical parametrization EPAX. In addition, a few one- and two-proton pickup

Programming support for reconfigurable custom vector architectures

High performance requirements increased the popularity of unconventional architectures. While providing better performance, such architectures are generally harder to program and generate code for. In this paper, we present our approach to ease programmability and code generation for such architectures. We present a domain specific language (DSL) for the programming part, and a constraint programm

Etik som praxis

En del saker berör människor till den grad att gängse normer och idéer ställs på huvudet. Synen på kroppen och hälsan är ett sådant fenomen. Längtan efter en speciell slags kropp är en historiskt välkänd drivkraft med konsekvenser för hur samtiden utformas. Den moderna biovetenskapen utgör i det sammanhanget en betydelsefull arena för mötet mellan människors drömmar och samhällets riktlinjer. Här
