Internal combustion engine (ICE) exhaust gases provide a high amount of energy which is partially lost to the environment. Such can be recovered with turbocharger turbine or other after-treatment device. As flow varies not only load but also opening and closing valves, proper matching between should established maximize recovery waste energy. That why twin-scroll dual turbocharging system imple...

The paper presents a construction design and results of laboratory tests so-called mechanical stress detectors, which can be used to detect the deformation steel structure crane amplify signal from effect skewing, is included among occasional loads acting on crane. values relative elongation detectors corresponding magnitude instantaneous tensile force were obtained by conducting experimental t...

introduction cerebral haemorrhage could complicate post operative course after cardiac surgery, especially after multiple mechanical valves replacement needing for anticoagulation. the interruption of vitamin k antagonists in this cases, to avoid the enhancement of the cerebral haemorrhage, can be performed with reasonable safety. case presentation we report the case of a patient who underwent ...

A unique and potentially useful fluid configuration which is possible in zero gravity is the liquid cylinder. One example is floating-zone crystal growth which, in zero gravity, involves a cylindrical melt bridging two solid cylinders. In low gravity, when the length of a cylindrical liquid bridge exceeds it's circumference, the bridge becomes unstable and breaks. A liquid bridge of length L an...

CFD Aided Development of a SI-DI Engine — Gasoline Direct Injection (GDI) appears to be the most relevant way to improve fuel efficiency of SI engines. But today, GDI is essentially regarded as a suitable technology for relatively high displacement engines, and the literature shows that the R&D effort on GDI engines is generally made for bores larger than 80 mm. For small bore engines (bore bel...

intelligent wells provide the ability for monitoring and control of downhole environment of the wells. downhole monitoring is achieved through sensors while control is realized with downhole valves. recovery from intelligent wells can be improved by proper selection of candidate wells/fields and optimizing the number, location and performance of the installed interval control valves. design cri...

In this paper we present a novel procedure for contour-based recognition of partially occluded three-dimensional objects. In our approach we use images of real and rendered objects whose contours have been deformed by a restricted change of the viewpoint. The preparatory part consists of contour extraction, preprocessing, local structure analysis and feature extraction. Themain part deals with ...

During their operation, modern aircraft engine components are subjected to increasingly demanding operating conditions, especially the high pressure turbine (HPT) blades. Such conditions cause these parts to undergo different types of time-dependent degradation, one of which is creep. A model using the finite element method (FEM) was developed, in order to be able to predict the creep behaviour...
