Jet impingement cooling is commonly used in gas turbines. Usually the spent air from the upstream jets forms a cross-flow past the downstream jets, which degrades their heat transfer performance. In the present study, a new method was proposed to promote the jet penetration and enhance the impingement heat transfer. By placing a delta-winglet vortex generator pair (VGP) in the cross-flow upstream

Here, we propose a new procedure for output feedback design for systems with nonlinearities satisfying quadratic constraints. It provides an alternative for the classical observer-based design and relies on transformation of the closed-loop system with a dynamic controller of particular structure into a special block form. Asymptotic stability is shown using Lyapunov theory with strictly positive

Background: The aim of this study was to compare QOL among people in India using lower-limb prostheses or orthoses with people without disability. A further aim was to compare subgroups and investigate whether QOL was associated with physical disability, gender, income, living area, and education. Methods: A cross-sectional questionnaire study in which the World Health Organization Quality of Life

Isothermal titration calorimetry (ITC) is an apt tool for a total thermodynamic description of self-assembly of atypical amphiphiles such as anionic boron cluster compounds (COSAN) in water. Global fitting of ITC enthalpograms reveals remarkable features that differentiate COSAN from classical amphiphiles: (i) strong enthalpy and weak entropy contribution to the free energy of aggregation, (ii) lo

Objective: To investigate recombinant human insulin-like growth factor 1 complexed with its binding protein (rhIGF-1/rhIGFBP-3) for the prevention of retinopathy of prematurity (ROP) and other complications of prematurity among extremely preterm infants. Study design: This phase 2 trial was conducted from September 2014 to March 2016. Infants born at a gestational age of 230/7 weeks to 276/7 weeks

Denna rapport kartlägger och undersöker företag som deltagit i det nationella inkubatorprogrammet (NIP) 2005–14. Uppgifter om de företag som funnits i inkubatorerna kommer från Vinnova. Dessa har sedan länkats till registerdata av Statistiska Centralbyrån vilket gjort det möjligt att analysera hur det gått för inkubatorföretagen efter inkubation. Rapporten undersöker inkubatorföretagens ekonomiska

This study examines cross-linguistic influence (CLI) in adult Italian-German bilinguals based on the production of gemination, a phenomenon that exists in Italian but not in German. We analyzed the spontaneous Italian speech of two groups of Italian-German bilinguals (heritage speakers of Italian and Italian-dominant bilinguals) and a monolingual Italian control group. The results show that the ge
