We show how to use a balanced wavelet tree as a data structure that stores a list of numbers and supports efficient range-selection queries. A range-selection query takes a rank and the endpoints of a sublist and returns the number with that rank in that sublist. For example, if the rank is half the sublist’s length, then the query returns the sublist’s median. If someone gives us a list of the...

Academics and practitioners have written much about what they believe are the key characteristics of effective marketing and strategy, including their view of any distinguishing supreme virtue, practice or goal. Similarly, philosophers, theologians and others have long speculated about what would be the greatest virtue, practice or goal of individuals and/or groups, but this is seldom if ever d...

We model virtue as an asset on the marriage market: since men value virginity in prospective mates, preserving their virtue increases girls’ chances of getting a "good" husband, and therefore allows for upward social mobility. Consistent with some historical and anthropological evidence, we find that the diffusion (and the social value) of virginity, across societies and over time, can be deter...

Novel ship concepts, increasing size and speed, and strong competition in the global maritime market require that a ship’s hydrodynamic performance be studied at the highest level of sophistication. All hydrodynamic aspects need to be considered so as to optimize trade-offs between resistance, propulsion (and cavitation), seakeeping or manoeuvring. VIRTUE takes a holistic approach to hydrodynam...

This essay explores virtue ethical concepts in the context of animal law theory and practice. For reasons discussed in the essay, virtue ethics may not, on its own, serve as an adequate foundation for general anticruelty statutes, but it may have application in those contexts in which sufficient sharing of values enables participants in legal reform to work through differences in moral commitme...

Ernest Sosa has long defended bi-level virtue epistemology on the grounds that it offers the best overall treatment of epistemology’s central issues. A surprising number of problems “yield to” the approach (Sosa 1991: 9). Sosa applies bi-level virtue epistemology to diagnose and bypass ongoing disputes in contemporary epistemology, including the disputes between foundationalists and coherentist...

Abstract. This paper presents a vision system for the task of actively acquiring and modeling the geometry of an unknown object. Using an active trinocular stereo head (VIRTUE), sensed 3-D line segments are grouped into a polyhedral volumetric model through the aid of a constrained Delaunay triangulation. Partial models and a viewpoint enumeration scheme are used to guide the image acquisition ...
