Strategy-controlled reduction and narrowing [chapter]

Peter Padawitz
1987 Lecture Notes in Computer Science  
"Uniformity" turns out as the crucial property of those reduction strategies which serve as complete narrowing strategies.  ...  A b s t r a c t The inference rutes "reduction" and "narrowing" are generalized from terms resp. equations to arbitrary atomic formulas.  ...  The paper at hand focuses on goal reduction and narrowing w i t h regard to strategies that control the selection of reduction resp. narrowing redices, While reduction redices are instances of tefthand  ...

Influence of Stance Width on Frontal Plane Postural Dynamics and Coordination in Human Balance Control

Adam D. Goodworth, Robert J. Peterka
2010 Journal of Neurophysiology  
We tested the hypothesis that when subjects adopt a narrow stance width, they will rely heavily on nonlinear control strategies and coordinated counter-phase upper and lower body motion to limit center-of-mass  ...  In narrow stance, CoM frequency-response function gains were reduced with increasing stimulus amplitude and in EO compared with EC; in wide stance, gain reductions were much less pronounced.  ...  This strategy, termed the "hip strategy," has long been recognized to contribute to stance control in conditions where the BoS is very narrow (Horak and Nashner 1986) and when very rapid corrections  ...

Analysis of Rewrite-Based Access Control Policies

Claude Kirchner, Hélène Kirchner, Anderson Santana de Oliveira
2009 Electronical Notes in Theoretical Computer Science

Prevention of Hepatitis C Virus in Injecting Drug Users: A Narrow Window of Opportunity

Jason Grebely, Gregory J. Dore
2011 Journal of Infectious Diseases  
Irrespective of the strategy used, intensification of harm reduction programs must consider the generally narrow time window from initiating injecting to HCV infection [14, 23] .  ...  However, randomized controlled trials evaluating HCV interventions, including combined strategies, are required.  ...

Avoiding traffic jams: Hitchhiking behavior as a strategy to reduce ant workers' traffic on the foraging trail

Isabel Neto Hastenreiter, Juliane Floriano Santos Lopes, Roberto da Silva Camargo, Luiz Carlos Forti
2018 Behavioural Processes  
Head-on encounter rates cause a reduction in travel speed and, furthermore, are regulatory factors of task-allocation.  ...  We counted the number of hitchhikers and the outbound worker flow. The frequency of hitchhikers increased along narrow trails, and also due to outbound workers in both trail widths.  ...  One strategy observed is the reduction of fragment sizes cut when in high traffic of individuals (Farji-Brener et al., 2011) .  ...
