Abstract: Disclosed are a method and a system for scheduling a task in cloud computing. The feature information of the task is parameterized; the task is classified; the best working node is obtained by computation through a Bacteria Foraging Optimization Algorithm (BFOA) according to the classification result; and the best working node is matched with the task. Obviously, the BFOA is adopted to implement task scheduling and resource allocation in cloud computing, so that the cloud computing has the advantages of group, intelligent and parallel search, simplicity in escaping from a local minimum and the like for the scheduling of a user task group, is favourable for keeping the diversity of the task group in the cloud computing, can meet the requirement of the user better, and improves the degree of satisfaction of user experience.

Abstract: A readily portable handheld security assessment device that may be manipulated for viewing the underside of objects having low ground clearance, including a high intensity light source coupled with an optical conduit adapted for uniformly illuminating the field to be viewed. A flexible ball joint assembly allows a reflector or mirror to be easily and controllably positioned and oriented under the object to facilitate visual inspection thereof while permitting the user to remain erect.

Abstract: A portable vehicle inspection system including a series of mats into which two lengths of flexible, polymeric side light transmitting optical fiber extend along channels placed near the edges of the mats, and at a distance to be within the tracks of wheels of a vehicle passing thereover, with the polymeric fiber optic including notches and a reflector directed to provide a steady, uniform flood of light up to the underside of a vehicle to be inspected, and between the inspection zone, and the light source, the polymeric optical fiber is covered by an opaque jacket to prevent light from radiating outward.
