Space Approach

A state space approach is taken to vehicle merging on high speed highways. The vehicles are assumed to be traveling in equal sized “slots” which move at the group velocity. At points where two or more lanes merge, some vehicles must be moved forward or backward to other slots to accomplish the merge. The state of a group of vehicles to be merged is defined in terms of the slots occupied at any time. A finite set of admissible terminal states, representing possible merged configurations, is easily determined. The sequence of moves required to obtain a merge is found as a shortest path in the space of all states, running from the initial state to the terminal manifold. Various costs may be applied to moves in this space, such as time consumed, or number of vehicles being moved simultaneously. Costs may also be assigned to the terminal arrangements, reflecting, for example, the size of platoons in the resulting merge. Estimates are made of required computing load and the method is compared with other approaches.

If the tilt of a specimen can be varied either by the strategy of observing identical particles orientated randomly or by use of a eucentric goniometer stage, three dimensional reconstruction procedures are available (l). If the specimens, such as small protein aggregates, lack periodicity, direct space methods compete favorably in ease of implementation with reconstruction by the Fourier (transform) space approach (2). Regardless of method, reconstruction is possible because useful specimen thicknesses are always much less than the depth of field in an electron microscope. Thus electron images record the amount of stain in columns of the object normal to the recording plates. For single particles, practical considerations dictate that the specimen be tilted precisely about a single axis. In so doing a reconstructed image is achieved serially from two-dimensional sections which in turn are generated by a series of back-to-front lines of projection data.
