Abstract: The invention relates to a vehicle headlight cleaning apparatus. A main body of the cleaning apparatus is of a cylindrical structure and internally provided with a compression spring and a movable seal valve which is matched with the inner wall of a casing of the cleaning apparatus. Both ends of the spring are respectively fixed on the end part of the cleaning apparatus and a spring fixing seat of the movable seal valve. When cleaning solution flows in the cleaning apparatus through a cleaning solution inlet on a base, the pressure of the cleaning solution overcomes the spring force of the compression spring and drives a transmission guide rod, the movable seal valve and a nozzle to move together, and the transmission guide rod stops when moving to a limit position. The pressure of the cleaning solution increases continuously, then the movable seal valve is opened under the pressure of the cleaning solution, the cleaning solution sprays out through the transmission guide rod and the nozzle, and a complete cleaning circuit is formed. When cleaning is finished, the pressure of the cleaning solution disappears, the movable seal valve is closed under the function of the compression spring, the transmission guide rod retracts into the casing till to an initial position, and the whole cleaning is finished. The invention has small and exquisite appearance, light weight, reliable work and high cleaning efficient.

Abstract: Provided herein are methods and systems for designing a radiation treatment for a subject using single arc dose painting. The methods and systems comprise an algorithm or a computer-readable product having the same, to plan the radiation treatment. The algorithm converts pairs of multiple leaf collimation (MLC) leaves to sets of leaf aperture sequences that form a shortest path single arc thereof where the pairs of MLC leaves each aligned to an intensity profile of densely-spaced radiation beams, and connects each single arc of leaf apertures to form a final treatment single arc. Also provided is a method for irradiating a tumor in a subject using single arc dose painting.

Abstract: A system and method for predictive analysis includes generating an execution trace on an instrumented version of source code for a multithreaded computer program. Interleavings which potentially lead to a violation in the program are statically generated by performing a static predictive analysis using a Universal Causality Graph (UCG) to generate alternative interleavings that might lead to an error. The UCG includes a unified happens-before model for the concurrent program and a property being analyzed. The interleavings are symbolically checked to determine errors in the program.
