BACKGROUND Current guidelines recommend using remote patient monitoring (RPM) for implantable cardioverter-defibrillators, but the patterns of adoption of this technology have not been described. Successful use of RPM depends on (1) the enrollment of the patient into an RPM system and (2) subsequent activation of RPM by the enrolled patient. We examined RPM enrollment and activation rates and t...

1Cr11Ni2W2MoV is a new martensitic heat-resistant stainless steel utilized in the manufacturing of aero-engine high-temperature bearing components. Welding this type using fusion welding techniques causes many defects. Friction stir (FSW) valuable alternative. However, few investigations have been performed on FSW steels because high melting point and costly tools. Numerical simulation regard c...

Currently, the aluminum alloys are utilized more in level of all industries for different applications; furthermore, need high-strength making innovative components. For those reasons, many researchers hope to prepare hybrid metal matrix composites at various composition levels. In this experimental work, we intended such as alloy 7079 with reinforcement ZrO2 + Si3N4 through stir-casting proces...

A central composite rotatable design with four independent variables viz. blend ratio (broken rice flour and cowpea flour): 90:10–70:30, moisture content (10–18% wet basis), barrel temperature (110–150 °C), screw speed (280–360 rpm) were varied in the development of ready-to-eat snacks using a twin extruder for broken rice–cowpea product. The effects on specific mechanical energy, water absorpt...

During the start-up process, air foil thrust bearings (AFTBs) come into contact and are prone to localized overheating even failure. Frequent starts stops major sources of wear. In this study, a transient mixed lubrication model considering rarefaction effect is established. model, asperity between top bearing (AFTB) rotor surface considered using deterministic approach, deformation structure e...

The paper describes the history of viscous-inviscid interaction methods, and tries to put them in a modern domain-decomposition context. This history started in 1904, when Ludwig Prandtl presented thèboundary layer' at the Third International Mathematical Congress in Heidelberg. From that moment on, the ow eld around a body was divided in two parts: a thin shear layer where viscosity plays a ro...

Compound casting is an efficient method for bonding dissimilar metals, in which a dramatic reaction can occur between the melt and solid. The centrifugal process, type of compound casting, was applied to cast Al/Mg bimetals. Magnesium poured at 700°C, with melt-to-solid volume ratios (Vm/Vs) 1.5 3, into preheated hollow aluminum cylinder. preheating temperatures solid part were 320, 400, 450°C,...

The heat penetration into the solid bed of rotary drums was experimentally investigated. An indirect heated rotary drum with a diameter of D=600 mm and a length L=450 mm has been used for this purpose. Temperature profiles of the gas, the drum wall and the solid bed were measured using 16 Type K thermocouples assembled on both a rotating and a fixed rod that attached inside the drum. Hence, the...
