Thermal bridging in the building envelope is one of main causes energy losses, even high-efficiency ventilated façades. In this study, effects point-thermal bridges attributed to metal fasteners on heat transferred through different types bricks were predicted. All structural details substrate wall included as well. This was accomplished with a multi-scale, finite element modelling approach use...

Sociolinguistic research has increasingly turned to examining the use of both the grammar and speech events of black speech by non-Blacks. This phenomenon called language crossing is defined as “the use of language varieties associated with social or ethnic groups that the speaker does not normally ‘belong’ to” (Rampton 1995:14). Although the literature has focused on phonological features, the...

This paper describes the design of an X-Band Magnetron to Linear Accelerator (LINAC) High Power Transfer System consisting in an 8 resonant cavities Magnetron connected to a dedicated vacuum Dielectric Window (DW). A main analytical design of devices is shown with compact formulas and is followed by numerical optimization. Electromagnetic and Thermomechanical coupling between these devices is d...

Abstract Plasma spray-physical vapor deposition (PS-PVD) as a novel process was used to prepare feather-like columnar thermal barrier coatings (TBCs). This special microstructure shows good strain tolerance and non-line-of-sight (NLOS) deposition, giving great potential application in aero-engine. However, due serious service environment of aero-engine, particle erosion performance is weakness ...

An analytical solution of the Boussinesq equations for the motion of a viscous stably stratified fluid driven by a surface thermal forcing with large horizontal gradients (step changes) is obtained. This analytical solution is one of the few available for wall-bounded buoyancy-driven flows. The solution can be used to verify that computer codes for Boussinesq fluid system simulations are free o...
