Purpose of this paper To develop an efficient Surface-Plane Intersection algorithm for direct slicing of freeform surfaces to be produced by layered manufacturing. Design/methodology/approach A semi-analytical method for direct slicing has been formulated and tested on Bezier and B-spline surfaces commonly used in CAD modeling. This method solves for the intersection points by a ‘root’ finding ...

On November 30, 2010, the European Commission opened an antitrust investigation into allegations that Google Inc. has abused a dominant position in online search in violation of Article 102 of the Treaty on the Functioning of ...

This paper studies the changes in electrical resistivity of an organic-rich source rock chalk containing a Type-IIs kerogen during early-stage maturation kerogen. As bitumen is generated maturation, from water wet to complex mixed-wet pore system, with micritic space remaining while expelled into macro pores converts some oil wet. system results non-Archie behavior pronounced curvature I-S w cu...

Over the past several years, a number of information discovery and access tools have been introduced in the Internet, including Archie, Gopher, Net nd, and WAIS. These tools have become quite popular, and are helping to rede ne how people think about wide area network applications. Yet, they are not well suited to supporting the future information infrastructure, which will be characterized by ...

“What they all overlook is the fact that they came to know Chelonia long after it had been cut down to a mere trace of its primitive abundance. They either hunt it today in the few places where schools hold out, or they take the trickle of waifs and stragglers that still faintly outline the old great feeding range of the species. The young men of today catch about as many turtles in a season as...

Preserving the Quality of Architectural Tactics in Source Code by Mehdi Mirakhorli In any complex software system, strong interdependencies exist between requirements and software architecture. Requirements drive architectural choices while also being constrained by the existing architecture and by what is economically feasible. This makes it advisable to concurrently specify the requirements, ...
