3D conflict avoidance under uncertainties
2009 IEEE/AIAA 28th Digital Avionics Systems Conference, 2009This paper presents a 3D conflict avoidance algorithm in the presence of uncertainty. The objective of the algorithm is to ensure the safety of the airspace in the event of a failure in the communication, navigation or surveillance systems. The algorithm minimizes the number of maneuvers required to maintain the safety of the airspace under degraded ...

Risky dispersal: avoiding kin competition despite uncertainty
Ecology, 2010Leaving a population without having information about the surrounding areas is highly risky. Candidates for dispersal may reduce these risks by making decisions based on the level of connectivity between patches, e.g., through immigrants. The benefits of information acquisition may vary within a population according to the dispersal cause and the ...

Sensory uncertainty impacts avoidance during spatial decisions
Experimental Brain Research, 2017When making risky spatial decisions, humans incorporate estimates of sensorimotor variability and costs on outcomes to bias their spatial selections away from regions that incur feedback penalties. Since selection variability depends on the reliability of sensory signals, increasing the spatial variance of targets during visually guided actions should ...

Avoiding uncertainty in Hofstede and GLOBE [PDF]
Journal of International Business Studies, 2010 This paper compares the Uncertainty Avoidance (UA) dimension of national culture across the Hofstede and GLOBE models, looking at relationships in both data and analysis. Rather than mutual support, we detail major differences and anomalies across the studies.

Uncertainty avoidance and cost stickiness
2023Submission note: A thesis submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy to the Department of Accounting, La Trobe Business School, College of Arts, Social Sciences and Commerce, La Trobe University, Bundoora.A recent development in research on cost behaviour is the emergence of the concept of sticky cost ...

Collision Avoidance Under Uncertainty
SPIE Proceedings, 1989Reasoning with uncertainty has increasingly become an important issue in robot path planning. The injection of doubt into the knowledge of obstacle location calls for capabilities not available in the conventional path planners. This work redefines the concept of optimality within the context of an uncertainty grid and proposes a class of cost ...

Tax Uncertainty and Incremental Tax Avoidance
The Accounting Review, 2018ABSTRACT We investigate whether tax avoidance becomes more uncertain as the rate of tax avoidance increases. We estimate a system of equations to demonstrate that as firms' pretax income increases, each additional dollar of potential tax results, on average, in 32.8 cents of tax avoided, which we refer to as incremental tax avoidance. Of

Uncertainty in Collision Avoidance Manoeuvring
Journal of Navigation, 1990Meeting encounters, in which it is uncertain at what range the give-way ship will manoeuvre, are analysed using a model based on probability theory. Course alteration ranges of both giveway and (if necessary) stand-on ships are closely fitted by a simple mathematical model, which is also used to interpret the efficiency of the Collision Regulations.

Collision avoidance under bounded localization uncertainty
2012 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2012We present a multi-mobile robot collision avoidance system based on the velocity obstacle paradigm. Current positions and velocities of surrounding robots are translated to an efficient geometric representation to determine safe motions. Each robot uses on-board localization and local communication to build the velocity obstacle representation of its ...
