JobPlan --- a new integrated representation and planner for batch job workflow automation
No full textThis dissertation presents a new representation and action logic for integrated planning, scheduling, execution monitoring and sensing. These features were motivated by the problem of computer batch job management but are applicable to any domain entailing these forms of reasoning. The existing planning literature has primarily focussed on providing highly efficient representations and algorithms which address specific aspects of planning and sensing. However no single planning framework currently combines the requisite integrated abilities of managing durative triggered actions in an open world environment. The dissertation's contributions are a multi-purpose planning and sensing representation and an associated partial order action logic to support these features. Plans and beliefs are represented as a workflow state machine governed by a clearly defined dynamics. Time based goals are handled by treating time as a fluent. The implementation and evaluation of a prototype planner ``JobPlan" on key domain scenarios illustrating these features is presented.Ph.D.Includes bibliographical referencesIncludes vitaby Tracey D.

To summarize the extensive and comprehensive GoMRI-funded ecological/ecosystem impact research (“Core 3”) conducted during the GoMRI tenure (145 projects, 661 publications to date), the Core 3 leadership group organized the ensemble information into four major ecotypes: coastal, continental shelf, benthic, and open-ocean. Such an effort requires cross-cutting integration to develop higher-level takeaway syntheses for future decision making. One useful approach is to rank key taxa in terms of oil spill risk, a product of taxon-specific vulnerability and resilience to oil spill events. Here we summarize the post-spill population dynamics of the open ocean fauna based on available information, highlighting the numerous data gaps that exist (e.g., pre-spill abundance data, information on life-history processes, quantified exposure metrics). Numerous taxa exhibited dramatic population declines since the oil spill, likely the confluence of high vulnerability and low resilience capacity. Other taxa exhibited small population decreases, suggesting low vulnerability (perhaps due to avoidance capacity) and/or high resilience (high productivity over short time frames). For many taxa, the dispersion capacity of the open gulf may have exacerbated the impact of the spill rather than ameliorated it. Evidence suggests the potential of an ecosystem-level cascade that may indicate an altered ecosystem state in the oceanic Gulf of Mexico. Continued ecosystem monitoring is therefore critical to fully understand the dynamics of the putative impacts to, and the latent recovery capacity of, the gulf’s open-ocean ecotype
An upper bound on the Chebotarev invariant of a finite group
No full textA subset {g1,.., gd} of a finite group G invariably generates {g1x1,..,gdxd} generates G for every choice of xi ∈ G. The Chebotarev invariant C(G) of G is the expected value of the random variable n that is minimal subject to the requirement that n randomly chosen elements of G invariably generate G. The first author recently showed that C(G)≤β|G| for some absolute constant β. In this paper we show that, when G is soluble, then β is at most 5/3. We also show that this is best possible. Furthermore, we show that, in general, for each ε > 0 there exists a constant cε such that C(G)≤(1+∈)|G|+c

Deep-sea sampling on CMarZ cruises in the Atlantic Ocean – an Introduction
No full textThe deep-sea zooplankton assemblage is hypothesized to have high species diversity, with low abundances of each species. However, even rare species may have huge population sizes and play a critical role in the dynamics of deep-sea environments. The Census of Marine Zooplankton (CMarZ) study sought to accurately assess zooplankton diversity in the mesopelagic and bathypelagic zones of the subtropical/tropical of the northwest and eastern sections of the Atlantic Ocean using integrated morphological and molecular analysis of large-volume samples to depths of 5,000 m. The field surveys in April 2006 and November 2007 included scientists and students associated with the CMarZ. The cruise field work entailed at-sea analysis of samples and identification of specimens by expert taxonomists, with at-sea DNA sequencing to determine a barcode (i.e., a short DNA sequence for species recognition) for selected species. Environmental data and zooplankton samples were collected with 1-m2 and 10-m2 opening/closing MOCNESS (0–1000 m and 1000–5000 m, respectively), and with either a 0.25-m2 MOCNESS or a 0.5-m2 Multi-net above 1000 m. More than 500 species were identified and more than 1000 specimens placed in a queue for barcoding on each cruise; several hundred species were barcoded at sea. For several taxonomic groups, a significant fraction of the region’s known species were collected and identified. For example, in the northwest Atlantic 93 of 140 known ostracod species for the Atlantic Ocean were collected, 6 undescribed species were found, and the first DNA barcode for a planktonic ostracod was obtained. The deployment of trawls with fine-mesh nets to sample large volumes at great depths for small zooplankton confirmed that there is considerable species diversity at depth, with more species yet to be discovered.<br/
