Because of heavy weights and large turning radii, large truck (LT) movements have very different characteristics than those of smaller vehicles, such as passenger cars. This difference makes collection of LT volume data very important for accurate analysis of traffic stream characteristics in transportation planning and engineering. Since LT travel patterns are seasonal, data obtained by survey...

This report describes unique surveillance system on a section of I-80 freeway in the city of Emeryville. The system, called the Berkeley Highway Laboratory (BHL), consists of eight dual loop detector stations along the freeway section, and 12 video cameras. Advanced machine vision algorithms were developed to process the video data to generate vehicle trajectories. Efforts are underway to fuse ...

We use the AdS/CFT duality to study the special point on the Coulomb branch of N = 4 SU(N) gauge theory which corresponds to a spherically symmetric shell of D3-branes. This point is of interest both because the spacetime region inside the shell is flat, and because this configuration gives a very simple example of the transition between D-branes in the perturbative string regime and the nonper...

We investigate the design of future energy storage systems by exploring one particular solution, in simulations. We use Lithium-ion batteries for storage, a dual active bridge (DAB) for DC to DC conversion and a synchronverter to transfer energy from the DC bus to the utility grid. We show how some recent improvements to the synchronverter algorithm can be combined with a battery management alg...
