Under Sleeper Pads: Field Investigation Of Their Role In Detrimental Impact Mitigation, Sakdirat Kaewunruen, Alex M. Remennikov Jun 2015

Under Sleeper Pads: Field Investigation Of Their Role In Detrimental Impact Mitigation, Sakdirat Kaewunruen, Alex M. Remennikov

Under sleeper pads (USPs) are the component installed under the concrete sleepers generally to improve railway track resilience. Initial development in Europe, particularly in Austria, has encouraged the adoption of the component around the world. In practice, the component has commonly been used in certain applications, mainly to moderate track stiffness in special locations such as turnouts, crossings, and level crossing. In heavy haul operation, the heavier wagons result in sturdier bogie structures, higher unsprung mass, and then higher level of wheel-rail interaction forces. Accordingly, the application of USPs to mitigate detrimental impact load consequence on track structure is presented …

Thermal Vs. Photonic Sintering Of Nano Silver Based Conductive Inks, Bilge N. Altay, Paul D. Fleming May 2015

Thermal Vs. Photonic Sintering Of Nano Silver Based Conductive Inks, Bilge N. Altay, Paul D. Fleming

Conductive ink formulations with different electrical properties and their sintering methods after printing are an emerging area of interest. In this work, different line width and resolutions were printed on a a flexible PET substrate using a nano silver based conductive ink with gravure printing. Then printed traces were sintered with two different sintering methods and the results were compared.

Color And Texture Morphing With Colloids On Multilayered Surfaces.Pdf, Shumin Li Mar 2015

Color And Texture Morphing With Colloids On Multilayered Surfaces.Pdf, Shumin Li

Shumin Li

ABSTRACT: Dynamic morphing of marine species to match with environment
changes in color and texture is an advanced means for surviving, self-defense, and
reproduction. Here we use colloids that are placed inside a multilayered structure to
demonstrate color and texture morphing. The multilayer is composed of a thermal
insulating base layer, a light absorbing mid layer, and a liquid top layer. When external
light of moderate intensity (∼0.2 W cm−2) strikes the structure, colloids inside the
liquid layer will be assembled to locations with an optimal absorption. When this
system is exposed to continuous laser pulses, more than 18 000 …
