This paper investigates both positional dependence in systems with friction and the influence an increase in temperature has on the friction behavior. The positional dependence is modeled with a Radial Basis Function network and the temperature dependence is modeled as a first order system with the power loss due to friction as input, eliminating the need for temperature sensing. The proposed meth

This work concerns an experimental study of pressure drop and heat transfer for turbulent flow inside a U-duct with relevance for tip cooling of gas turbine blades. The U-duct models the internal blade cooling flow passages. Both friction factors and convective heat transfer coefficients were measured along the bend (turn) part of the U-duct for three different rib configuration cases, namely (a)

Popular Abstract in Swedish Vi lever i ett samhälle under ständig utveckling där användandet av nya kemikalier ökar explosionsartat. Med vardagligt användande av avancerade material såsom extremt tunna skärmar, billiga och miljövänliga bekämpningsmedel och läkemedel – vilka ofta är inspirerade av naturens komplexitet – kommer ett behov av organisk syntes. För att tillverka den här typen av komplicThis thesis deals with the development of novel methodologies for the synthesis of hetero- and carbocycles enabled by transition metal catalysis. The second chapter of the thesis describes a gold-catalyzed three-component reaction to form a variety of substituted oxazoles from readily available N-benzylimines, terminal alkynes, and acyl chlorides. Sacrificial benzyl groups are used to merge two o

High S/N echelle data of chi Lupi have been obtained at 36 different wavelength settings. The high resolution of the observations combined with the low rotational velocity of chi Lupi (v sin i approximate to 1 km s(-1)), allow the UV spectrum of this star to be seen with unprecedented detail, and provides a unique resource for the study of both atomic physics and stellar atmospheres.

Popular Abstract in Swedish Proteinkinas C i nervcellsutveckling Under fosterutvecklingen ska en enda cell, den befruktade äggcellen, ge upphov till alla de högt specialiserade celler som människokroppen består av. Den process där omogna celler utvecklas till t.ex. nervceller, blodceller och muskelceller kallas differentiering. Det som avgör vad en speciell cell ska utvecklas till är bl.a. vilka sThe human neuroblastoma cell line SH-SY5Y can be induced to differentiate into a neuronal sympathetic phenotype after treatment with 16 nM 12-O-tetradecanoyl phorbol 13-acetate (TPA) in serum, or by a combination of the growth factors basic fibroblast growth factor and insulin-like growth factor-I (bFGF/IGF-I). SH-SY5Y cells stably transfected with TrkA, the nerve growth factor (NGF) receptor, dif

Abstract in Danish Fyrst Ekelöf har fornyende indsigt at give til os alle i Norden i disse år. Den svenske digter Gunnar Ekelöf (1907-1968) er en moderne mystiker. Denne bog tegner et mangefacetteret billede af Ekelöf som østerlandsk vismand, der fører Østen ind i Norden. Han får os til at tænke på uortodokse måder – og i multikulturelle perspektiver. Gunnar Ekelöf værk afspejler tankens k
