Laser-based additive manufacturing (LBAM) is a promising manufacturing technology that can be widely applied in solid freeform fabrication (SFF), component recovery and regeneration, and surface modi®cation. The thermal behaviour of the molten pool is one of the critical factors that in ̄uences laser deposition indices such as geometrical accuracy, material properties and residual stresses. In t...

Objective: Current research is aimed to emphasize the use of bio-based composites in form thermal insulation, achieving complete degradability. Low density bio-composites have gained moderate importance as its development primitive stage because processing and preparation issues. Methods: A preliminary investigation carried out based on results selected reinforcements Eggshell (ES), Groundnut P...

Thermal image is an image that shows the thermal or temperature properties of an object. Thermal image of an object is obtained from a thermal infrared camera. This camera works by employing radiative heat transfer principles and uses sensors to capture the radiated energy of an object. Thermal image of an object in the real world which is captured by a thermal camera is a real thermal image of...

Physical aspects of the thermofield dynamics of the D = 10 heterotic thermal string theory are exemplified through the infrared behaviour of the one-loop dual symmetric cosmological constant in association with the global phase structure of the thermal string ensemble. ∗e-mail: [email protected] ∗∗e-mail: [email protected] Elaboration of thermal string theories based upon the thermofield dyn...

Altered pain responding in depression is a widely recognized but poorly understood phenomenon. The present study investigated nociceptive responding to acute (thermal and mechanical) and persistent (inflammatory) noxious stimuli in two animal models of depression, the olfactory bulbectomized (OB) and the Wistar-Kyoto (WKY) rat. In addition, this study examined if altered nociceptive behaviour w...

Introduction: Thermal feedback from collector power to emitter temperature has been shown to significantly affect BJT performance.’-4 Recently several worker^^.^ have demonstrated ways to model this thermal feedback in circuit simulation assuming that thermal model parameters are available. This Letter introduces a simple way to extract thermal parameters needed for such simulations. BJT therma...

The thermal-stress resistance and fracture strength behaviour of two oxide ceramics (a hot-pressed pure AI203 and a composite ceramic NTK-HC2) subjected to severe thermal shocks have been investigated. The damage resistance parameter (Kic/of)2 for both ceramics is also determined for a wide range of temperatures (25 ~ to 800 ~ C) and cross-head rates (10 -2 cm min -1 ~ 2.5 m sec -1 ). Fracture ...

We describe a variety of intriguing mode-coupling effects which can occur in a confined Bose-Einstein condensed system at finite temperature. These arise from strong interactions between a condensate fluctuation and resonances of the thermal cloud yielding strongly non-linear behaviour. We show how these processes can be affected by altering the aspect ratio of the trap, thereby changing the re...
