Vilket är världens största utmaning idag? En del säger utstampandet av terrorismen. Andra menar att det är miljöproblematiken. Själv tror jag att HIV/AIDS katastrofen i världens utvecklingsländer ska rankas högt. I väst förefaller epidemin vara under någorlunda kontroll tack vare nya effektiva mediciner. Däremot sprids farsoten med en ständigt ökande takt i u-länder. 25%, ibland upp till 35-40% av
The use of nanoparticle-based pseudostationary phases (PSPs) in capillary electrochromatography (CEC) for separation of small molecules and proteins is demonstrated. A continuous full filling approach is used where the nanoparticles are suspended in the electrolyte. A new interaction phase is introduced for every analysis, which eliminate problems with stationary phase-based carry-over effects. H
In this paper the balanced truncation procedureis applied to a time-varying linear system, both in continuous and in discrete time. It is discussed how to obtain the reduced-order systems by using certainprojections instead of direct balancing. An approximative zero-order-hold discretization of continuous-time systems is described, and a new a priori approximation error bound for balanced truncati
Model-based analysis of in-cylinder pressure sensor signals has been a key component for internal combustion engine research, diagnostics and controller development during the past decades. This analysis is often based on simple thermodynamic models of the in-cylinder processes. In order for the analysis to give accurate results, the models need to be sufficiently calibrated. This paper investigat
But almost two years into this diplomatic crisis in Iranian-British ties, the collision course has already started to reverse thanks in important part to the election of centrist President Hassan Rouhani and his government’s determination to mend fences with the west through pursuing a moderate agenda.
