In this paper we propose a new approach to coordinate multiple machines in the grain harvesting process, based on meta-constraint reasoning. This way we obtain more flexible plans that can be adapted at execution time. As an example scenario we focus on silage maize harvesting. We argue that more sophisticated flexible planning mechanisms are needed in order to obtain flexible plans that can be...
While universal plans tell a system how to reach a goal regardless of what state it is in, such plans can be too large to represent. Hybrid systems execute plans where each action is implemented to robustly produce effects if the world does not stray outside the action’s control envelope. This paper presents a middle ground between these two extremes that uses plans, but also enables much large...
Cap and trade remains attractive to many state governments because it provides a much-needed source of additional revenue when greenhouse gas emission allowances are auctioned to the highest bidder. We analyze the income distribution impacts of the California Global Warming Solutions Act under alternative policy designs. These include the free allocation of emission allowances versus recycling ...
We present a transform that enables traditional Shortest-Feasible-Plan planners to reason about uncertain operators and produce plans which have higher probabilities of success. This transform converts a probability-aware domain description into a STRIPS-style description, where the probability of success is expressed by plan length. Using this transformed description a plan can be generated by...
sunn pest, eurygaster integriceps put., is the most important pest of wheat and barley in most producing regions of iran, including lorestan province. spatial distribution and fixed precision sequential sampling plans of sunn pest by the use of two quadrate sizes 0.25 and 0.5 m2 were investigated in rainfed wheat fields in borujerd during 2004 and 2005. based on r square of regression, taylor&a...
Background and aims: Visit quality is a crucial component of patient-physician interaction that its inadequacy can negatively influence the diagnosis and treatment efficiency. The waiting time and visit length are important determinants of quality in the outpatient care setting. Thus, the aim of this study was to determine waiting time and visit length and to compare them befor...
We study the problem of designing efficient auctions where bidders have interdependent values; i.e., values that depend on the signals of other agents. We consider a contingent bid model in which agents can explicitly condition the value of their bids on the bids submitted by others. In particular, we adopt a linear contingent bidding model for single minded combinatorial auctions (CAs), in whi...
Previous studies of employee investment in retirement plans suggest that people typically "naively diversify" their investment funds, tending to allocate 1/n of the total to each of n available instruments (Benartzi & Thaler, 2001). In this paper we provide experimental evidence that this bias extends to allocation among simple chance prospects and demonstrate three new violations of rational c...
The existence of torsion, as well as consideration of the Soil-Structure Interaction (SSI), increase the natural periods of the structure resulting from a subsequent decrease in the seismic demand of the system. This paper summarizes the probabilistic assessment for evaluation of collapse fragility curves in concrete moment resisting structure with different mass center eccentricities. A 12-sto...
In an influential model of frontal eye field (FEF) and superior colliculus (SC) activity, saccade initiation occurs when the discharge rate of either single neurons or a population of neurons encoding a saccade motor plan reaches a threshold level of activity. Conflicting evidence exists for whether this threshold is fixed or can change under different conditions. We tested the fixed-threshold ...
