International Conference on Mechanical Design and Simulation 60 Accesses Abstract Due to its excellent performance, three-dimensional composites are an ideal choice for components in the aerospace and automotive fields. However, the need for smooth operation and productivity of current braiding equipment ...
inclination towards self-aggregation or binding to molecular scaffolds, and (2) it continues to be challenging to completely restrict the interaction between digestive enzymes and their substrates due to the absence of membranes and the consequent dynamic exchange with their counterparts in the external...
Photoactuators and photoluminescent dyes utilize light to perform mechanical motion and undergo spontaneous radiation emission, respectively. Combining these two functionalities in a single molecule would benefit the construction of advanced molecular ma
The first issue was currency exchange rates. Since 1949, the value of the Japanese yen had been fixed at ¥360 to one U.S. dollar. The Nixon Administration’s decision in August 1971 to abandon the gold standard, which had kept the value of the dollar relatively stable, led to the co...

For collecting thermodynamic measurements, the CopterSonde is outfitted with a suite of three iMet-XF PT 100 thermistors (International Met Systems, Grand Rapids, MI, USA) and three HYT 271 capacitive relative humidity sensors (Innovative Sensor Technology, Ebnat-Kappel, Switzerland). These sensors...
