Fretting Corrosion in Electric Contacts

Fretting corrosion is a form of accelerated atmospheric oxidation which occurs at the interface of contacting materials undergoing slight, cyclic relative motion. In electric contacts involving non-noble metals, fretting action can cause rapid increases in contact resistance, proceeding to virtual open circuits in a matter of minutes in the worst cases. Experimental results of resistance increa...

Greedy Õ(C +D) Hot-Potato Routing on Trees

In hot-potato (deflection) routing, nodes in the network have no buffers for packets in transit. A hotpotato routing algorithm is greedy if packets are advanced from their sources toward their destinations whenever possible. The dilation D is the longest distance a packet has to travel; the congestion C is the maximum number of packets that traverse any edge. The routing time of a routing-algor...

Nonabelian Phenomena on D-branes

A remarkable feature of D-branes is the appearance of a nonabelian gauge theory in the description of several (nearly) coincident branes. This nonabelian structure plays an important role in realizing various geometric effects with D-branes. In particular, the branes’ transverse displacements are described by matrix-valued scalar fields and so noncommutative geometry naturally appears in this f...

Electric Phenomena in Relation to Lubrication

General. The effect of shaft currents passing through an oil film in a bearing is to accelerate polymerization and oxidation and cause thermal decomposition. The oil darkens in colour, sometimes increases in acidity, and generally deposits a chocolate-colour precipitate in the oil system. Arcing will also cause small particles of metal to flake off and contaminate the oil. If a shaft current is...
