Direct Metal Laser Sintering (DMLS) was introduced to meet the objective of producing metal parts directly from CAD data. CRDM has accumulated six years of experience in applying this technique, mostly to prototyping parts for evaluation. For some applications, such as blow moulds, porosity generated in DMLS has proved to be beneficial, but for others a concession on tolerances or finish are ne...

PURPOSE For simple pharmacokinetic compartmental models, analytical solution to the governing differential equations along with common graphical methods provide a mean to evaluate the associated rate constants. These graphical methods, however, can not be used for the more complex multi-compartment models. Furthermore, parameter estimation using slope and intercept values from the graphical met...

This poster shows how HPCN can be used as a pathnding tool for turbulence research. The parallelization of direct numerical simulation of turbulent ow using the data-parallel model and Fortran 95 constructs is treated, both on a shared memory and a distributed memory computer. Introduction Computer simulation has become a major tool for studying turbulent ow in many technological and environmen...

This paper presents a case study of data mining modeling techniques for direct marketing. It focuses to three stages of the CRISP-DM process for data mining projects: data preparation, modeling, and evaluation. We address some gaps in previous studies, namely: selection of model hyper-parameters and controlling the problem of under-fitting and over-fitting; dealing with randomness and 'lucky' s...

Deterministic optimization algorithms, that are combination of direct search methods and local search algorithms, are proposed for molecular conformation problems. We apply these methods to solve the Lennard-Jones atomic cluster problem. The deterministic optimization algorithms are embedded in a build-up scheme. At each stage, an atom is added to an optimized structure of a small cluster, and ...

Ceramic full crowns can restore lost tooth structure, strength, and esthetics but remove about twice as much tooth as an onlay design. Onlay restorations can maintain facial enamel for long-term esthetics, preserve the dentogingival junction for optimum periodontal health, and use supragingival margins for predictable adhesive dentistry. Metallic onlays can create fracture strength 3 times that...
