To increase the filling of cylinder in engine, a so-called charge is applied, which consists increasing amount air input under increased pressure and at an unchanged temperature. This increases density that mass engine cylinder. In most cars, charging carried out by exhaust gas turbocharger or mechanical compressor. paper presents issues concern failure turbochargers resulting from their balanc...

The IBM eServer z990 microprocessor implements many features designed to give excellent performance on both newer and traditional mainframe applications. These features include a new superscalar instruction execution pipeline, highbandwidth caches, a huge secondary translation-lookaside buffer (TLB), and an onboard cryptographic coprocessor. The microprocessor maintains zSeries leadership in RA...

More than 90% of the microprocessors produced today are used in embedded devices. With the current development tools, it is exceedingly difficult to debug, profile, and update code running on embedded devices in operation. This leaves developers unable to diagnose and solve software issues on deployed embedded systems, something that is unacceptable for an industry where robustness is paramount...

Experimental and numerical studies for the structural vibration serviceability assessment of a historic suspension footbridge adopting non-invasive surveys low-cost equipment are presented. Field have been carried out to determine geometric properties, ambient tests performed estimate dynamic response under action single crossing pedestrian has recorded. Based on field surveys, 3D Finite Elemen...

The change in the stress-strain state is analyzed on example of a complex underground part silo "loess soil base – foundation strip undersilo tunnel gallery compacted bottom slab" system as an indicator for assessing serviceability this type industrial structure.
 Based analysis existing design documentation and field surveys, main stages structure's operation during its construction subse...

A grade-separated crossing allows a bicycle/pedestrian to continue over or under barrier without conflict with vehicle. However, the serviceability of these facilities is compromised in underdeveloped countries, including Pakistan. This research examines effectiveness pedestrian bridges and underpasses terms their usage by pedestrians. total 80,017 crossings were observed at four sites (3 overh...
