Minimization of label usage in (G) MPLS network

The paper considers a problem of minimizing the total number of labels that are necessary to realize a given set of end-to-end connections in a GMPLS transport network where traffic is handled by means of Label Switched Paths-connections established using the label switching principle. The problem is important for the networks where labels are a scarce/expensive resource, like in optical networks.

Development and validation of a system for the generation, characterization and subsequent air- liquid interface studies of aerosol particles

Popular Abstract in Swedish Tänk dig ett system som kan bestämma hur olika typer av luftpartiklar skadar oss när dom hamnar i våra lungor. Ett system som dessutom kan skapa luftpartiklar för dessa studier vid behov och med väl uppmätta egenskaper. Denna avhandling handlar om just ett sådant system och experiment som är viktiga för att förstå om och hur det fungerar. Systemet kallas i denna avhandlExposure to nano-sized and nanostructured aerosol particles with tailored properties are likely to increase in society. Occupational exposure to various kinds of nanostructured aerosol particles such as soot and metal aggregates already exists. To understand the adverse human health effects of these particles, there is a need for systems that can Generate a stable output of aerosol particles, Char

Attenuation of tumor growth by formation of antiproliferative glycosaminoglycans correlates with low acetylation of histone H3.

Glycosaminoglycan (GAG) chains anchored to core proteins form proteoglycans, widely distributed cell-surface macromolecules with multiple functions, such as regulation of growth factor and cytokine signaling, cell-cell interactions, and uptake of biomolecules. The biosynthesis of GAG can be manipulated by xylosides attached to various hydrophobic groups, and we have earlier reported that a naphtho

Axelns sjukdomar

The authors were requested to analyse the frequency of shoulder surgery at the different orthopaedic units of Sweden and to propose national indications according to evidence in literature.(nko.se) Three main groups of shoulder disorders were studied: subacromial pain, shoulder instability and pain caused by degenerative glenohumeral pathology. About 6500 shoulders were operatively treated in Swed

Ossicular Bone Modeling in Acute Otitis Media.

BACKGROUND AND OBJECTIVE:: A number of middle ear diseases are associated with pathologic bone modeling, either formative or resorptive. As such, the pathogenesis of a sclerotic mastoid has been controversial for decades. Experimental studies on acute middle ear infection have shown progressive osteoneogenesis in the bone structures surrounding the middle ear cavity, and a few studies have reporte

Personaliserad nutrition och etik : en empirisk studie av svenska konsumenters inställning till gentester för hälsans skull

Abstract In this thesis I address some of the ethical issues that arise in relation to consumers and personalised dietary advice made on the basis of genetic information. By carrying out two empirical studies, I wanted to find out what Swedish consumers think about personalised nutrition, and how they reason regarding risks, possible value conflicts, and benefits that may arise from implementing t

Lund High-power Laser Facility - Systems and 1st Results

A high-power laser facility has been established at the Lund Institute of Technology, Sweden, available to national groups and their international collaboration partners. The laboratory incorporates three major 10 Hz laser systems, that can be operated individually or synchronized in combined use. Each system represents extreme optical powers in a certain sense. The main system is a terawatt laser

Traveling waves for the Whitham equation

The existence of traveling waves for the original Whitham equation is investigated. This equation combines a generic nonlinear quadratic term with the exact linear dispersion relation of surface water waves on finite depth. It is found that there exist small-amplitude periodic traveling waves with sub-critical speeds. As the period of these traveling waves tends to infinity, their velocities approac

On the physical limitations of the interaction of a spherical aperture and a random field

This paper derives physical limitations on the interactions of antennas exciting TM or TE modes (but not both) and wireless propagation channels. The derivation is based on the spherical vector wave expansion of the electromagnetic field outside a sphere circumscribing the antennas. The result is an extension of the seminal work of Chu on the classical limitations on maximum antenna gain and radia

Historielöshet bakom rädsla för invandring

De största invandringsvågorna till Sverige har sammanfallit med de epoker då riket utvecklats allra mest. Historien ger oss inga rimliga skäl att betrakta immigration som ett problem – tvärtom kan dess betydelse för vårt välstånd knappast överskattas.
