The total core loss in a claw-pole structure has been calculated on the basis of the variation of the magnetic loading over the magnetization cycle in different parts of the machine. This variation has been estimated from a lumped parameter permeance network and 3D finite element simulations, studying the flux density waveform and loci in their elements. The results from the simulations are compar

Nonlinear axisymmetric finite element analyses are performed on the uniaxial compressive test of concrete cylinders. The models include thick steel loading plates, and cylinders with height-to-diameter ratios (h/d) ranging from 1–3 are treated. A simple constitutive model of the concrete is employed, which accounts for the strain hardening and softening in the pre- and postfailure regions, respect

Interest in learning in mature adulthood has become increasingly important as attention has been focused on what is seen to be an impending crisis in the near future, i.e., shortage of labour due to the ever-growing number of elderly and decreasing nativity rates. In some circles "alarmist demographics" have overshadowed an arguably more important concern, that of providing for aging individuals'

A numerical implementation of a rigorous theory to analyze scattering by randomly located obstacles is presented. In general, the obstacles can be of quite arbitrary shape, but, in this first implementation, the obstacles are dielectric spheres. The coherent part of the reflected and transmitted intensity at normal incidence is treated. Excellent agreement with numerical results found in the liter

Varje program och kurs på Lunds universitet skall få en genuscertifieringsstämpel. Universitetets lärare skall tvingas vara genusmedvetna och bland de studerande skall det finnas en genusombudsman. Professor Tiina Rosenberg vid Centrum för genusvetenskap har initierat en ny form av kontroll och härskarteknik, skriver socialantropologen Steven Sampson.

Med utgångspunkt från begreppet professionell handledning presentera i detta kapitel faktorer som kan vara viktiga för utvecklingen av en god handledningsrelation.

I Ungas samarbete - Nordens framtid ger unga människor runt om i Norden sin bild av nordisk samverkan och hur den kan utvecklas. När ungdomar som tidigare inte haft möjligheten att delta i nordiskt samarbete ges förutsättningar att skapa mötesplatser, växer både ungdomarna själva och deras intresse för nordisk samverkan. Nokon, ett nordiskt samverkansprojekt inom arbetsmarknadsområdet som pågått u

A microfluidic device for particle washing was designed utilizing an acoustic standing wave field in a micro channel. Particles were focused in the center of the channel by the acoustic radiation force while the original carrier media was shifted sideways (orthogonal to the flow) at a number of consecutive wash fluid flow junctions along the main flow. Experiments were carried out in order to comp
