Collision avoidance control with sensing uncertainties

Proceedings of the 2011 American Control Conference, 2011
Sensing and localization mechanisms, employed by mobile robots for the detection of obstacles and other nearby agents, may inaccurately estimate the position of obstacles due to noise, delays, and interferences incurred during the detection process. Therefore, it is critical to design collision avoidance strategies that are robust to the presence of ...

Collision Avoidance Behaviour and Uncertainty

Journal of Navigation, 1978
When radar was first introduced to the merchant fleets of the world, many people felt that a practical solution to the collision avoidance problem had been found. However, a review of worldwide collision statistics of the past 20 years indicates that, in spite of the expanded use of radar, the over-all collision rate remains alarmingly high. Because of

Tax Avoidance, Uncertainty, and Firm Risk

SSRN Electronic Journal, 2019
We examine the relation between tax avoidance and firm risk using latent class mixture models, identifying subsamples of firms with differing relations between variables of interest. We provide evidence that 19 percent of our sample exhibits a positive association between tax avoidance and firm risk, 42 percent exhibits a negative association, and 39 ...

Entrepreneurial Orientation, Uncertainty Avoidance and Firm Performance

The International Journal of Entrepreneurship and Innovation, 2003
This study examines the relationship between entrepreneurial orientation (EO) and firm performance in a sample of 306 Vietnamese SMEs and 172 Thai small and medium-sized enterprises (SMEs). Dimensions of entrepreneurial orientation including risk-taking, proactivity and innovativeness are explored.

Uncertainty Avoidance, Loss Aversion and Stock Market Participation

SSRN Electronic Journal, 2020
Abstract Stock market participation differs a lot across countries. Cultural dimensions could be a potential factor for that. We show that indeed uncertainty avoidance (UAI) is linked to rates of stock market participation across countries. We can show even more that uncertainty avoidance has an indirect effect through loss aversion on stock market ...

Accounting for State Uncertainty in Collision Avoidance

Journal of Guidance, Control, and Dynamics, 2011
An important consideration in the development of aircraft collision avoidance systems is how to account for state uncertainty due to sensor limitations and noise. However, many collision avoidance systems simply use point estimates of the state instead of leveraging the full posterior state distribution.

Economic policy uncertainty and firm tax avoidance

Accounting & Finance, 2019
AbstractWe find strong evidence that firms reduce cash effective tax rate when economic policy uncertainty heightens. Firms also engage in more aggressive forms of tax avoidance including long‐term tax planning or shelters. Cash holdings attenuate the negative effect of policy uncertainty on cash effective tax rate, especially for financially ...

Uncertainty Avoidance, Face-Saving, and Organizations

2017
Chapter 8 describes the cultural dimension uncertainty avoidance. The chapter begins with a representative example to explain how those with high uncertainty avoidance also feel more stress, try to maintain the status quo, prefer structure, formalization, rules, and rituals because they are predictable.

Uncertainty Avoidance in Greece: An Ethnographic Illustration

1998
‘Uncertainty avoidance’ is the name of one of the five (originally four) dimensions of ‘culture’ that Geert Hofstede has given to the world of management academia and management consultancy. Hofstede’s work is familiar to many, but a brief description is given here, to provide a context for our own argument.
