Over the last 20 years ubiquitous computing has become reality. Phones, household appliances,TVs, cars, and even buildings have essentially become computers. interacting with computing technologies has become an integral part of our life. Embedded computers more and more shape how we perceive the world and how we interact with each other. By creating ubiquitous computing technologies we inevita...

The aim of this study was to investigate the feasibility of using nonmetallic printed circuit board (PCB) waste as filler in recycled HDPE (rHDPE) in production of rHDPE/PCB composites. Maleic anhydride modified linear low-density polyethylene (MAPE) was used as compatibilizer. In particular, the effects of nonmetallic PCB and MAPE on mechanical properties of the composites were assessed throug...

Extensive test data exist on the ignitability of nonmetallic materials in pure oxygen, but these characteristics are not as well understood for lesser oxygen concentrations. In this study, autogenous ignition temperature testing and pneumatic impact testing were used to better understand the effects of oxygen concentration on ignition of nonmetallic materials. Tests were performed using oxygen ...

In this work the effect of microstructural homogenization and solution annealing prior to ageing on mechanical properties fatigue resistance 18Ni300 maraging steel parts processed by laser powder bed fusion (L-PBF), using two different feedstock powders with N O contents is investigated. The static are not significantly affected selection powders. This ascribed extremely fine size nonmetallic i...
