System identification of linear multivariable dy-namic models based on discrete-time data can be performed using a algorithm combining linear regression and LQG-balanced model reduction. The approach is applicable also to unstable system dynamics and it provides balanced models for optimal linear prediction and control.
In this paper we introduce two new methods for solving binary quadratic problems. While spectral relaxation methods have been the workhorse subroutine for a wide variety of computer vision problems - segmentation, clustering, image restoration to name a few - it has recently been challenged by semidefinite programming (SDP) relaxations. In fact, it can be shown that SDP relaxations produce better
We present calculations of charm and beauty production at Tevatron within the framework of k(T)-factorization, using the unintegrated gluon distributions as obtained from the Linked Dipole Chain model. The analysis covers transverse momentum and rapidity distributions and the azimuthal correlations between b and (b) over bar quarks (or rather muons from their decay) which are powerful tests for th
With the growth of mobile computing, users will have simultaneous access to multiple overlaid networks, each with different characteristics, services and costs. This paper introduces TOMTEN (TOtal Management Of Transmissions for the ENd-user), a framework for managing resources in both this type of environment as well as the traditional single network environment. TOMTEN is a reactive framework th
We present a new type of nanometer-scale semiconductor nonlinear device, called self-switching device (SSD). The device was realized by simply etching insulating grooves into a semiconductor, between which a narrow channel with a broken symmetry was formed. Because of the asymmetry in the channel boundary, an applied voltage V not only changes the potential profile along the channel direction, but
Autonomic computing systems adapt themselves thousands of times a second, to accomplish their goal despite changing environmental conditions and demands. The literature reports many decision mechanisms, but in most realizations a single one is applied. This paper compares some state-of-the-art decision making approaches, applied to a self-optimizing autonomic system that allocates resources to a s
Kan en havsanemon bli konståkare? När vi tittar på en person från sidan kan vi genast skapa oss en bild av hur den personen ser ut från andra sidan, men om vi tittar bakifrån kan vi inte avgöra hur denne ser ut framifrån. Hur kommer det sig? Anledningen har att göra med symmetri. Människor har ett spegelplan som går mitt mellan ögonen, men inget som går från öra till öra. D.v.s. om man speglar den
Under lång tid fanns inte någon specialreglering i svensk rätt gällande skadeståndsansvaret vid dammhaverier. I juli 1997 infördes en lag som förändrade detta och pekade ut ansvarssubjekt med ett rent strikt ansvar. Den underhållsskyldige för en dammanläggning innehar ett strikt ansvar för de skador som uppstår nedströms till följd av ett dammhaveri enligt 11 kap. 18 § miljöbalken. UnderhållsskylFor a long time, there was no regulation of the indemnity liability for dam failures in Sweden. In July 1997 a new law brought a change to this and clarified which liable entity was strictly liable for damages. The entity responsible for maintaining the dam bears a strict liability for all damages arising downstream as a consequence of a dam failure according to chapter 11 paragraph 18 in the Swe
The conventional agricultural production system is not sustainable. Organic agriculture is assumed to be sustainable from the environmental perspective, and its production and labelling has been regulated in the European Union (EU). The EU organic regime has been challenged by proponents of agroecology, a philosophy that merges agriculture and ecology and considers environmental and social aspects
Rapporten undersöker betydelsen för val av borrmetod när en formationsfilterbrunn ska dimens-ioneras. Dimensionering av filtrets slitsvidd görs med utgångspunkt från kornstorleksanalyser genom provtagning av borrkax. Ett formationsfilter byggs upp genom att tvätta bort en stor del av det finkorniga materialet i ett sedi-ment och låta de grövre partiklarna fungera som ett naturligt grusfilter runt This report examines the significance for the choice of drilling methods when dimensioning a formation well screen. Dimensioning the slot openings of the well screen is done by studying sediment samples by sieve anal-ysis. The sieve analysis shows the abundance of the particle size distribution in the aquifer, and the particles sam-pled should therefore give an adequate description of the real con
This paper argues that industrialized meat and dairy production create substantial environmental costs that are currently not being reflected by the price paid by consumers. One way of addressing this could be by taxing those products proportional to the environmental damage they cause based on the principle that the polluter should pay. The question is if such a tax could be legally motivated und
This study seeks to investigate how an affective perspective can contribute to an understand- ing of the space of Kanalens Kvarter in Albertslund, Denmark. From the perspective of the phenomenological approach, the thesis explores the aesthetics, social boundaries, and the use of the space in Kanalens Kvarter. I found a knowledge gap within the literature on street culture because emotions are put
