Naming requires recognition. Recognition requires the ability to categorize objects and events. Infants under six months of age are capable of making fine-grained discriminations of object boundaries and three-dimensional space. At 8 to 10 months, a child’s object categories are sufficiently stable and flexible to be used as the foundation for labeling and referencing actions. What mechanisms i...

This article proposes a new class of rating scale models, which merges advantages and overcomes shortcomings of the traditional linear and ordered latent regression models. Both parametric and semi-parametric estimation is considered. The insights of an empirical application to satisfaction data are threefold. First, the methods are easily implementable in standard statistical software. Second,...

Gaussian particles provide a flexible framework for modelling and simulating three-dimensional star-shaped random sets. In our framework, the radial function of the particle arises from a kernel smoothing, and is associated with an isotropic random field on the sphere. If the kernel is a von Mises–Fisher density, or uniform on a spherical cap, the correlation function of the associated random f...

The use of language mechanisms to enforce protection boundaries around software modules has become increasingly attractive. This paper examines the advantages and disadvantages of languagebased protection over more traditional protection mechanisms, such as standard virtual memory protection hardware, software fault isolation, and capability systems. Arguably, state-of-the-art language-based pr...

To meet with the requirement in virtual rendering, an OpenFlight mesh generation method based on B-Rep model is proposed. The bridge construction method, which is flexible for arbitrary multi-loop regions, are employed on model planes. In order to get the closed parametric region for the curved surface, Boolean trimming operations between surface grids and boundary poly-lines are implemented ef...

As e-business matures, companies require enterprise-scalable functionality for their corporate Internet and intranet environments. To support the expansion of their computing boundaries, businesses have embraced Web application servers. These servers support servlets, JavaServer Pages, and Enterprise JavaBeans technologies, providing simplified development and flexible deployment of Webbased ap...

The ATF damping ring [1] was built to demonstrate the production of low emittance, high current beams for future linear colliders. To attain high beam currents, multiple high current bunch trains are required. The low-level rf system should be designed to minimize both steady-state and transient beam loading effects in the accelerating cavities. In addition the design should be sufficiently fle...

In this paper, we present a method for constructing Loop’s subdivision surface patches with given G boundary conditions and a given topology of control polygon of the subdivision surface, using several fourth-order geometric partial differential equations. These equations are solved by a mixed finite element method in a functional space defined by the extended Loop’s subdivision scheme. The met...

Many people insist that their commitments to certain values (e.g. love, honor, justice) are absolute and inviolable - in effect, sacred. They treat the mere thought of trading off sacred values against secular ones (such as money) as transparently outrageous - in effect, taboo. Economists insist, however, that in a world of scarce resources, taboo trade-offs are unavoidable. Research shows that...
