20th National conference on Artificial Intelligence and the 17th Innovative Applications of Artificial Intelligence conference, AAAI-05/IAAI-05

Self stabilization in distributed systems is the ability of a system to respond to transient failures by eventually reaching a legal stale, and maintaining it afterwards. this makes such systems particularly interesting because they can tolerate faults, and are able to cope with dynamic environments. We propose the first self stabilizing mechanism for multiagent combinatorial optimization, which works on general networks and stabilizes in a state corresponding to the optimal solution of the optimization problem. Our algorithm is based on dynamic programming, and requires a linear number of messages to find the optimal solution in the absence of faults. We show how our algorithm can be made super-stabilizing, in the sense that while transiting from one stable state to the next, our system preserves the assignments from the previous optimal state, until the new optimal solution is found. We offer equal bounds for the stabilization and the superstabilization time. Furthermore, we describe a general scheme for fault containment and fast response time upon low impact failures. Multiple, isolated failures are handled effectively. To show the merits of our approach we report on experiments with practically sized distributed meeting scheduling problems in a multiagent system.

this object of study was to modulate soil water content from water balance model by using GIS. the study area was cultivated area of Phitsanulok province, thailand. the spatial resolution of grid data used in the analysis was 40*40 meter and temporal resolution was weekly accounted for 52 weeks. the results showed that average annual rainfall, average annual evaporation pan, average annual runoff, and average annual deep percolation were 2,094, 2,540, 516, and 150 m3/rai, respectively. these variables were later calculated together to determine soil water content. the computation showed that average annual soil water content was 97 m3/rai. Soil water content was accumulated starting from week 18th to week 3rd of the next year and maximized in week 37th(75.5m3/rai). the soil water-based suitable week for cultivating 3 crop types;vegetable, field crop and rice;appeared from week 20th to week 47th (28 weeks), week 20th to week 45th (25 weeks), and week 23rd to week 42nd (19 weeks), respectively. However, the suitable areas were decreased when these areas were considered on a combination criteria between soil water content suitability and soil property suitability.

20th Biennial conference on Mechanical Vibration and Noise

Friction is a difficult phenomenon to model and simulate. One promising friction model is the LuGre model, which captures key frictional behavior from experiments and from other friction laws. While displaying many modeling advantages, the LuGre model of friction can result in numerically stiff system dynamics. In particular, the LuGre friction model exhibits very slow dynamics during periods of sticking and very fast dynamics during periods of slip. this paper investigates the best simulation strategies for application to dynamic systems with LuGre friction. Several simulation strategies are applied including the explicit Runge-Kutta, implicit Trapezoidal, and implicit Radau-IIA schemes. It was found that both the Runge-Kutta and Radau-IIA methods performed well in simulating the system. the Runge-Kutta method had better accuracy, but the Radau-IIA method required less integration steps.

the development of a hybrid knowledge-based system with a coupling between knowledge-based and numerical methods for multiobjective optimization of power distribution operations is described. the advantages of a hybrid knowledge-based system are described followed by the system objectives, means of control, and constraints. A framework is provided that describes the necessary development stages of a commercial knowledge-based package. An overview of the utility knowledge acquisition procedure is provided to appreciate the complexity of defining the rule base. this is followed by a description of the flow of information in a three-level hierarchical rule base and a summary of network radiality, parameter, and performance rules employed in this rule base. After a heuristic preprocessor identifies a list of switch closures that would seem to reduce total system losses, network radiality rules assess if a particular search path has identified a switch that can be closed and a corresponding switch opened to maintain the radiality of the system or if the path is worth pursuing further. Network parameter rules ensure the system operates within original design parameters. Network performance rules assess the reduction in total system losses of each proposed switching operation. Where there is a coupling between knowledge-based and numerical methods, the integration of numerical methods is described. Finally, the validation and simulations as well as the benefits of this hybrid knowledge-based system are described. Copyright © 2005, American Association for Artificial Intelligence (***).

Experimental compensation of runout and high order harmonic effects in lorentz force type integrated motor-bearing system

20th Biennial conference on Mechanical Vibration and Noise

An integrated motor-bearing system integrates the functions of an active magnetic bearing and an electric motor into a single unit. Because this system requires the simultaneous generation of torque and radial control force, there will inevitably be undesired high order harmonic components in the rotating magnetic field, which will result in torque ripple and radial force distortion. Sensor target runout is a severe excitation source and, as such, causes a lot of vibration. In this paper, we propose an experimental compensation procedure for the oscillation and coupling of torque and radial force using a digital controller of the Lorentz force type integrated motor-bearing system in a dual disk rotor configuration. After the compensation of high order harmonics, the runout profile and rotor unbalance are identified by the extended influence coefficient method. the proposed scheme does not require complicated analysis or modeling of high order harmonic effects, and it can also compensate for manufacturing errors. the experimental results confirm that this compensation method effectively attenuates the rotor vibration throughout the operating range of rotational speeds.

Refereed games are interactive proof systems with two competing provers: one that tries to convince the verifier to accept and another that tries to convince the verifier to reject. In quantum refereed games, the provers and verifier may perform quantum computations and exchange quantum messages. One may consider games with a bounded or unbounded number of rounds of messages between the verifier and provers. In this paper we prove classical upper bounds on the power of both one-round and many-round quantum refereed games. In particular we use semidefinite programming to show that many-round quantum refereed games are contained in NEXP. It then follows from the symmetric nature of these games that they are also contained in coNEXP. We also show that one-round quantum refereed games are contained in EXP by supplying a separation oracle for use with the ellipsoid method for convex feasibility.

Many salt marsh restoration and creation projects have been implemented in the Galveston Bay system during the past 20 years. Salt marshes have many valuable functions for the surrounding habitat and the animals living there. Some of these functions include physical functions such as protecting shorelines from erosion, stabilizing deposits of dredged material, dampening flood effects, trapping water-born sediments, and serving as nutrient reservoirs. Biological functions include acting as tertiary water treatment systems to rid coastal waters of contaminants, serving as nurseries for many juvenile fish and shellfish species, serving as habitat for various wildlife species, and providing plant material for the base of a detritus-based food web. Each year more marshes are being built, and yet very little information is available concerning the success of past restoration projects. In an effort to assist the Fishery Ecology Branch (FEB) of the National Marine Fisheries Service (NMFS) Galveston Laboratory monitor created marshes and obtain information concerning their success [1]. A prototype project to map and monitor these marsh habitats was undertaken. Further, a prediction model of the density and population of different fishery species in Galveston Bay was developed.

Policy-oriented energy system modeling with xeona 18

Policy-oriented energy system modeling with <i>xeona</i>

18th International conference on Efficiency, Cost, optimization, Simulation and Environmental Impact of Energy systems (ECOS 2005)

Energy systems exist to provide industry, commerce, and households with fuels and energy-services. In addition to financial cost and reliability imperatives, these systems are now being asked to perform across a range of sustainability criteria. Most national systems fall well short on this second count and governments need to promote a suitable transition. Market liberalization over the last 20 years has made this task more challenging in public policy terms and yet could provide good incentives for innovation, reinvestment, and user responsiveness, given the right institutional measures. the development of suitable public policy may necessitate sophisticated simulation techniques, particularly considering the technical and commercial complexities involved, the multi-criteria nature of the policy problem, and the fact that most interventions will interact. this paper presents xeona (extensible entity-oriented optimization-based network-mediated analysis), an object-oriented simulation environment designed for such use and currently under development. the modeling ethos is to represent important entities from the problem domain as elements within the simulation domain. Hence a xeona model is built from the ground up using the technical plant, controllers, markets, actors, and policy measures that exist in reality or are under consideration. the presence of actors allows low-stake commercial and domestic decision-making to be embedded within the model and thereby drive system evolution in response to commercial pressures and proposed policy interventions. Model construction is one aspect, but the specifics of policy usage and interpretation are also important. To this end, a technology evaluation issue involving neighborhood fuel cell cogeneration in northern Europe is briefly illustrated with numerical results.

A key step in program optimization is the determination of optimal values for code optimization parameters such as cache tile sizes and loop unrolling factors. One approach, which is implemented in most compilers, is to use analytical models to determine these values. the other approach, used in library generators like ATLAS, is to perform a global empirical search over the space of parameter values. Neither approach is completely suitable for use in general-purpose compilers that must generate high quality code for large programs running on complex architectures. Modeldriven optimization may incur a performance penalty of 10-20% even for a relatively simple code like matrix multiplication. On the other hand, global search is not tractable for optimizing large programs for complex architectures because the optimization space is too large. In this paper, we advocate a methodology for generating high-performance code without increasing search time dramatically. Our methodology has three components: (i) modeling, (ii) local search, and (iii) model refinement. We demonstrate this methodology by using it to eliminate the performance gap between code produced by a model-driven version of ATLAS described by us in prior work, and code produced by the original ATLAS system using global search.

Cold cathode fluorescent lamps (CCFL) for LCD TVs have a special v-i characteristic, which can make the backlight inverter system unstable. In this paper, modeling of both the cold cathode fluorescent lamp and the backlight inverter is performed in terms of incremental impedance in the frequency domain. the stability analysis of the backlight inverter and the CCFL is presented using the derived models. It is concluded that the time delay, after which the lamp voltage responds to the lamp current change, contributes to the incremental impedance of the CCFL at the high frequency region, which may cause instability of the backlight inverter. the time delay is considered as a lamp characteristic. the effect of the inverter design parameters on the stability is also investigated. the lamp model and the stability analysis results are verified from experiments with a backlight inverter for 32-inch LCD TVs. © 2005 IEEE.
