We present a new technique for modeling rectilinear volume data. The algorithm produces a trivariate model, F (x; y; z), which is piecewise de ned over tetrahedra that ts the volume data to within a user speci ed tolerance. The technique is adaptive leading to an e cient model that is more complex where the data demands it. The novelty of the present technique is that a valid tetrahedrization i...

A Gordon–Coons-type surface construction starts from three differentiable triangular surface patches, which are defined on the same triangular parameter domain. If one boundary curve of each fits a curvilinear triangle, then the defined surface interpolates to these curves. The connection between the resulting surface and the constituents is C1 continuous along the common boundary curves with t...

Last Tuesday. .May 2nd, the Ties/en award in chemistry was presented to P.radfurd Mundy 'HI A coffee hour was held for cheinislry majors at which time Dean Lanford presented Bradford with a check for $100 from an anonymous donor for promise in research and excellence in his course work in chemistry, physics, and mathematics. The chemistry department has announced the lour graduate assistants in...

This article discusses the story of Steven, a precarious academic worker, and his decision to work from home while being infected with Covid-19; phenomenon called virtual presenteeism. As argued, Steven’s sickness presence is outcome increasing precarity job insecurity in sector, as well presenteeism culture academia which facilitated by technology blended learning approach adopted during pande...

Increasing recognition of the extent and speed of habitat fragmentation and loss, particularly in the urban fringe, is driving the need to analyze qualitatively and quantitatively regional landscape structure for decision support in land-use planning and environmental policy implementation. The spatial analysis required in this area is not well served by existing spatial data models. In this pa...

The description of economic behavior as sequential decision making under uncertainty has been hampered by the limited nature of the available theoretical results. This paper tries to fill some of the gaps. In particular, the paper develops some basic results for the problem of search. We present a general formulation of the search problem in Section 2. Search is seen as sequential sampling from...

This paper presents Threaded Multi-Path Execution (TME), which exploits existing hardware on a Simultaneous Multithreading (SMT) processor to speculatively execute multiple paths of execution. When there are fewer threads in an SMT processor than hardware contexts, threaded multi-path execution uses spare contexts to fetch and execute code along the less likely path of hard-to-predict branches....
