Myopic search plans
Different strategies can be used to search for a moving object. If the searcher's action at each time unit maximizes his chances of immediate detection, his strategy is said to be myopic. If, however, the searcher seeks to allocate search effort to maximize the probability of detecting the target …

DETECTION AND OCCURRENCE OF NERODIA HARTERI (SERPENTES: COLUBRIDAE) IN AN UPPER PORTION OF THE BRAZOS RIVER WATERSHED
… community. Within occupied transects, search effort was positively correlated with detecting <em>N. harteri</em>, whereas environmental and/or habitat variables were better predictors for detecting the sympatric congeners. Microhabitat selection between the three <em>Nerodia</em> …

Salient Search
… this is inversely proportional to the amount of effort given to planning between each move. Many real-time algorithms employ a constant-bounded local search to plan a single move at a time. However they need multiple trials to converge on an optimal solution. More recent hierarchical approaches …

Firm growth and worker turnover in frictional labour markets
… introduces vintage effects and endogenous worker search effort. New start-up firms are created with a productivity drawn from a technology frontier which grows over time. However, as a given firm’s productivity is fixed, its quality declines relative to the market average. In addition, workers can …

An evolutionary approach to studying search behavior in the context of human mate selection
This research investigates the search behavior of individuals in the context of mate selection. That is, how much information individuals search for prior to initiating mating relationships? What information individuals deem important when searching for mates? How much information individuals …

Floral richness inventory of an eastern U.S. forest
… richness in eastern forests were compared: timed-search meanders, belt transects, and plots. Meanders and transects located more species in the same amount of time as plots. Plot sampling encompassed only two-thirds of the richness known from the site. Species-area and species-effort relationships …

Informed selection and use of training examples for knowledge refinement.
… of possible refinements demands a heuristic search. Refinement tools typically use hill-climbing search to identify suitable repairs but run the risk of getting caught in local optima. A novel contribution of this thesis is solving the local optima problem by converting the hill-climbing …

Event and map content personalisation in a mobile and context-aware environment.
… experiment. Participants solved situational search tasks using a (i) non-personalized and a (ii) personalized mobile information system, and rating entertainment events based on usefulness. Results showed that the personalised system delivered about 20% more useful content to the mobile user …

Flood Survival Strategies of Overwintering Snakes
… declined despite hundreds of hours of search-effort. At the population level this was evidence of poor winter survival and recruitment post flood. The direct cause of mortality was not determined but poor winter survival in areas with a depleted life zone was statistically supported. In …

Search for the Higgs Boson in the ZZ --> ℓℓvv channel with CMS
… [square root of]s = 7 TeV for the 2011 run. The search for the SM Higgs with the 2011 dataset represented the first major foray into the search effort by the LHC project. This thesis presents a search for the SM Higgs boson in the ZZ -->2ℓ2v channel from the analysis of 4.9 fb-1 of data collected …

Essays on Unemployment
… after that separation in terms of intensity of search effort and jobs pursued. I offer a richer understanding of what women do and how they feel in the aftermath of job loss. I also propose a more multifaceted view of the factors influencing unemployed women’s decision-making with respect to …

Essays in applied economic theory
… and insolvent cannot sell their home -- into a search model where agents face a restriction of job opportunities based on their net asset positions. Ultimately, agents in deep-enough negative equity and insolvency quit searching altogether, reducing labor supply and mobility. Data from the …

On the construction, dimensionality, and decoding of linear block code trellises
… we consider near-ML decoding using partial searches of a code trellis or tree. Despite the fact that this approach is suboptimal in terms of the probability of error, it has the potential for an improved trade-off between coding gain and computational effort. The decoding problem faced by a …

Essays on job search behavior and labor market policies
… of the impact of these programs on the job search behavior and the interplay with long-term labor market outcomes is necessary. This allows policy makers to improve the design of labor market policies and the allocation of unemployed workers into specific programs. Moreover, previous studies …

The foraging ecology of the short-tailed shearwater puffinus tenuirostris.
… revealed that 18 birds employed area restricted searches within circles of a diameter of 14 ± 3 km (SE). Prey returns from area restricted search flights were predominated by bony fish, whereas prey diversity increased for non-area restricted search flights, with more krill and cephalopods. Thus, …
