Based on a regular, causal descriptor controlled plant, the fault detection for a class of descriptor systems with both multiple measurement and control packet dropouts is investigated. Two independent Bernoulli distributed white sequences are used to describe the multiple measurement and control packet dropouts. The problem of fault detection for networked systems can be formulated as an H?? filtering...
Other than feedback linearization method used in 2 dimensional space, a new control strategy of multi-agent system in three dimensional space is proposed in this paper. Based on sliding mode control, artificial potentials are combined used in the control strategy. It can be widely adopted to deal with the nonlinear plant in three dimensional space, and used for tracking static or moving goals robustly...
In this paper we consider the mechanism design of traffic BOT project auction. We set up the model of traffic BOT project auction where firms bid on capacity and concession term, and bids are evaluated by a scoring rule designed by the auctioneer. We educe the optimal auction mechanism by analyzing the incentive compatibility. In addition, we find that the optimal capacity is chosen independently...
For the new signal acquisition methodology of compressive sensing (CS) a challenge is to find a space in which the signal is sparse and hence recoverable faithfully. Given the nonstationarity of many natural signals such as images, the sparse space is varying in time or spatial domain. As such, CS recovery should be conducted in locally adaptive, signal-dependent spaces to counter the fact that the...
This paper describes a new floorplanning approach called constrained adjacency graph (CAG) that helps exploring adjacency in floorplans. CAG extends the previous adjacency graph approaches by adding explicit adjacency constraints to the graph edges. After sufficient and necessary conditions of CAG are developed based on dissected floorplans, CAG is extended to handle general floorplans in order to...
In this paper we consider an extension of the traditional auction mechanism, the multi-attribute auction, which enables negotiation on several attributes in addition to the price of the item. In particular, we consider a procurement auction in which the buyer is the auctioneer and the sellers are the bidders. We set up the model of multi-attribute auctions where sellers bid on price and the other...
The internal rotations (of dimer models), geometries, energies, vibration spectra, dipole moments and molecular polarizabilities of poly (vinylidene fluoride) (PVDF) of alpha- and beta-chain models were studied with the first principle density functional theory (DFT). Electric properties of PVDF affected by chain lengths were examined. The chain length was also discussed to determine the chain stabilities...
