Modern aluminum casement windows consist of an inner and outer profile made of aluminum, which are separated by an insulating bar made of polyamide (see Figure 1). Due to the low heat conductivity of the plastic material the thermal interaction between the living space and the surrounding is reduced significantly, but thermal expansion of the different materials could cause elastic or even ...

With the ever changing energy requirements & demand for better communication links across the planet, subsea umbilical & cable requirements are becoming more stringent. Where longer service life at a lower cost is now expected from manufacturers. In addition to this, with the need to exploit more sustainable energy sources from offshore wind & wave, where extreme weather conditions are ...
Applied Superconductivity Center, National High Magnetic Field Laboratory, Tallahassee, FL, USA
High temperature superconductors (HTS) allow larger current densities through coil wound electromagnets, which produce higher magnetic fields. A high field HTS insert demonstration magnet is being built with high field homogeneity (~1 ppm) for application in nuclear magnetic resonance (NMR). The HTS NMR system is inserted into the bore of an existing high field magnet. A compensating Helmholtz ...

Uncertainty in COMSOL Multiphysics® software simulations due to (a) model parameter uncertainties and (b) mesh-induced truncation errors, is estimated using a design-of-experiments approach [1, 2, 3], and a nonlinear least squares logistics fit method [4, 5], respectively. Examples to illustrate both approaches are given using the COMSOL RF Module (in an application of a MRI coil design) and ...

A 3D thermo-mechanical simulation was developed using COMSOL Multiphysics software in order to predict distortion of a welded dissimilar titanium alloys structure. An angular distortion and a longitudinal shrinkage are predicted in agreement with those obtained experimentally.

Introducing a disorder into a finite periodic oscillatory system induces the presence of a 'trapped mode': a mode in which the displacement field is localised to the region of the disorder. A main inhibitor to MEMS resonators achieving a high quality (Q) factor is energy radiation through the support to the substrate. The trapped modes present a way to tune this to a minimal value. An initial ...

CV boots or gaiters are rubber like material used to cover & protect moveable or articulating components such as CV joints of a vehicle. These are primarily used to protect the articulating joint, by preventing the components from being exposed to the surrounding environment, the preventing the ingress of water, particulate or road grime from mixing with the lubricated articulated components. In ...

Encouraging students to take on a Science, Technology, Engineering, and Math (STEM) major has recently been a top priority in the nation’s policy-making debates. STEM-related majors often time are deemed very difficult and demanding. Specifically, students tend to face difficulties to conceptualize engineering problems which can eventually impede otherwise successful individuals from pursuing a ...

Materials with an order variable in thermal conductivity as a function of temperature are desirable for thermoelectric heat energy recovery, building thermal insulation and solar thermal applications. Thermal Conductivity is an inherent material property. Engineering the fundamental thermal conductivity needs manipulation at thermal photon level for conventional materials. Engineering thermal ...
