Research on Ant Colony Algorithm in Vehicle Operation Adjustment Based on IOT

Automatic solution of vehicle operation adjustment is the important content in realizing vehicle traffic command automation on Internet of Things platform. Based on both the organization realization of Internet of Things platform and the merging vehicle operation adjustment into the Flow-Shop scheduling problem in manufacturing systems, this paper has constructed the optimization model with a two-lane vehicle operation adjustment. With respect to the large model solution space and complex constraints, a better solution algorithm is proposed based on ant colony algorithm for optimal quick solution. The simulation results show that the algorithm is feasible and the approximate optimal solution can be quickly obtained.     

Chance-constrained model predictive control for spacecraft rendezvous with disturbance estimation

A robust Model Predictive Controller (MPC) is used to solve the problem of spacecraft rendezvous, using the Hill-Clohessy-Wiltshire model with additive disturbances and line-of-sight constraints. Since a standard (non-robust) MPC is not able to cope with disturbances, a robust MPC is designed using a chance-constrained approach for robust satisfaction of constraints in a probabilistic sense. Disturbances are modeled as Gaussian allowing for an explicit transformation of the probabilistic constraints into simple algebraic constraints. To estimate the distribution parameters a predictor of disturbances is proposed. Both robust and non-robust MPC control laws are compared using the Monte Carlo method, which shows the superiority of the robust MPC.

Review of The Robot's Rebellion: Finding Meaning in the Age of Darwin.

Review of book The Robot's Rebellion: Finding Meaning in the Age of Darwin by Keith E. Stanovich (see record 2004-95228-000). In his interesting scholarly book, The Robot's Rebellion, Stanovich leads us on a journey to find meaning in a world populated by mortal biological vehicles, the robots, put on earth to replicate their masters' selfish genes. If the genes do a satisfactory job programming the robots, then the genes replicate in perpetuity and are, therefore, immortal. Stanovich's basic assumptions are: a) vehicles are designed to replicate genes; b) at least in human animals, the brain houses two minds; c) the first mind, System 1 or The Autonomous Set of Systems, evolved much earlier in evolutionary history than did the second mind, System 2 or the Analytic System; d) System 1 is associative, parallel, fast to respond, and designed to automatically serve its genetic master; e) System 2 is rule-based, serial, slow to respond, not aware of System 1 functioning but sometimes privy to System 1 output, controls executive functioning, and is capable of self-evaluation and leading the rebellion against its genetic master; and, f) memes, culturally generated ideas passed on by nongenetic means, can sometimes be as effective as System 1 at squashing the rebellion. These assumptions are derived from work in cognitive science and evolutionary biology, and provide a solid foundation for the book. Both the metaphor and the basic assumptions are embedded in detailed and informative reviews of decision theory, evolutionary psychology, memetic theory, rational philosophy, and utility theory. The interweaving of metaphor and review provides a framework that allows Stanovich to make inferences to help the general reader understand "the implications of modern science" (p. xi). He also develops criteria to evaluate memes that are needed in his quest to find meaning in human existence. In combination with the basic assumptions, these criteria are used to create an ethical ideology that will be embraced by some readers.
