Turbulent Boundary Layer Flow Over a Bump
Turbulent boundary layers (TBLs) are critical to the performance and efficiency of many engineering systems, especially in aerospace and turbomachinery applications. While two-dimensional (2D) TBLs under zero-pressure-gradient (ZPG) conditions are well understood, real-world boundary layers often …

Bump control design protocol for room-and-pillar retreat mining
… protocol was developed to minimize coal mine bumps, which are the explosive failure of highly stressed pillars. The protocol was developed for room-and-pillar retreat mining conducted with available continuous miner technology. The inability of existing coal pillar equations to accurately …

Design, Modelling, and Test of an Electromagnetic Speed Bump Energy Harvester
Speed bump energy harvester, which aims to harvest energy from the passing by vehicles by absorbing their kinetic and potential energy, is designed, fabricated, simulated, and tested in this research. The proposed design is analyzed with a theoretical modelling which has then been validated with a …

The reminiscence bump in autobiographical memory: An investigation of the life script hypothesis
… to any other period of life. This reminiscence bump is evident for memories involving positive emotions but not for memories involving negative emotions. The life script hypothesis proposes that people share cultural knowledge for the types and timing of positive landmark events expected to …

Theoretical analysis of bump and airblast events associated with coal mining under strong roofs
This investigation was conducted to study the bump and airblast problems associated with delayed caving of competent longwall roofs. The roofs were modeled as elastic beams on continuous elastic foundations subject to exponentially distributed abutment stress. Elastic beam theory was applied to …

A ‘bump-&-hole’ approach for engineering allele-selective inhibition of the BET bromodomains
… lab has previously designed a proof-of-concept ‘bump-&-hole’ system to selectively target these bromodomains by mutating a conserved leucine to an alanine (L/A mutation) and adding an ethyl bump to an existing inhibitor scaffold (ET compound). This system was promising, but required optimisation …

Things That Go Bump in the Night: An Examination of Magical Thinking in Young Children
<p>Past research has shown that children as young as age 3 years are able to distinguish the difference between mental entities and real objects (Estes, Wellman, & Woolley, 1989). Yet, many children still display persistent fears of imaginary creatures, which they claim are not real. In the present …

Numerical analysis of TSV/micro-bump deformation due to chip misalignment and thermal processing in 3D IC packages
… the through-silicon vias (TSV) and solder micro-bumps are simulated through an applied shearing action. Thermal effects due to coefficient of thermal expansion (CTE) mismatch during processing are also studied to provide trends of stress and deformation fields. Reliability of the 3D chip stack, …
