Popular Abstract in Swedish Ett flertal produkter som framställs inom den kemiska och biotekniska industrin produceras i stora turbinomrörda tankar. Kvaliteten av produkten och utbytet av processen påverkas av blandningsförhållandena i dessa tankar. Blandningsförhållandena i processen påverkas av vätskans hastighet och dess intensitet. I olika regioner av reaktorn, impeller regionen och bulk regiTurbine-agitated tanks are used in chemical and biochemical applications to increase mixing which, in turn, affects the yield, productivity and product quality. The purpose of this work was to study the hydrodynamic influence on the scale-up of turbine-agitated tanks, commonly used in fermentation. Local turbulent flow parameters, the turbulent kinetic energy and the local energy dissipation rate,

A model is presented taking into account off line-of-action, non linear wheel stiffness by using the finite element method, and elasticity coupling between the gear teeth. The contact points are determined by searching the common normal using the undeformed, but otherwise true theoretical, tooth shapes where the teeth have a tip rounding to prevent contact singularity in off-line-of-action points.

As custom architectures become more and more common for DSP applications, instruction selection and scheduling for such applications and architectures become important topics. In this paper, we explore the effects of defining the problem of finding an optimal instruction selection and scheduling as a constraint satisfaction problem (CSP). We incorporate methods based on sub-graph isomorphism and g

Popular Abstract in Swedish Människans utveckling och fysiologiska anpassning till upprätt kroppställning är beroende av en rad blodtrycksreglerande mekanismer. Vid ortostatisk hypotension sjunker blodtrycket i samband med uppresning från liggande till stående. Detta beror på en sviktande cirkulationsanpassning så att organismen inte förmår att upprätthålla ett tillräckligt högt blodtryck. SymtomeOrthostatic hypotension (OH) is believed to be an important cause of cerebral hypoperfusion, leading to chronic fatigue, blurred vision, unsteadiness, dizziness and sometimes syncope. It may also result in episodes of confusion, falls and fractures. The coupling between OH and organic dementia is not clear. Our findings in a large group of patients with Alzheimer's disease, vascular- and frontotem

We present a summary of the activities of the Multi-Jet final states and energy flows Working Group of the HERA and the LHC workshop, 2007-2008. Among the more specific topics considered were the status of and recent progress in higher order calculations, both in fixed perturbative expansions and in resummed approaches, recent progress in the description of jets, including the description of forwa

A matched filter composed of a time lagged feedforward artificial neural Network (TLFN) and a pulse-shaping filter is used in a noisy environment to detect R-waves for pacemakers. The TLFN reduces the influence of lower frequencies in the invasive electrogram (EGM) signals, e.g. P and T waves, and conditions the EGM to optimize the performance of the dynamically updated matched filter. Detector pe

Under år 1999 genomfördes en arkeologisk förundersökning i form av schaktningsövervakning i Södergatan, Skomakaregatan, Per Weijersgatan och Baltzarsgatan i Malmö stad under år 1999. Arbetena berörde Malmö äldre stadsområde, registrerat som fornlämning 20 i Malmö stad enligt Riksantikvarieämbetets fornminnesinformationssystem (FMIS). Sammanlagt övervakades 65 schakt, äldre lämningar påträffades i
