Explaining how product works, how it could be used, and where it differs from existing technology, is the most difficult part and a decisive element in reaching commercial objectives. A 3D animation can be the solution, since it easily visualizes and explains the use and purpose of something that is hard to explain even in a thousand words. This paper will examine the challenges of presenting products and projects in the renewable energy sector and introduces the many advantages of 3D visualization to help achieve company's commercial objectives.

SP AusNet wanted to deploy a document viewing package that would allow internal staff and design contractors to access and view CAD and engineering drawings within the company's electronic document management system. The challenge was to provide a platform for designers and project teams to collaborate on engineering drawings. SP AusNet deployed Oracle's AutoVue 2D Professional to enable staff in the company's power transmission division to view around 350,000 CAD-based engineering drawings that illustrate site plans and layouts of terminal stations and buildings exactly as they would appear in AutoCAD.
233 days ago by Oracle DownloadThis paper proposes a generalized group-wise non-rigid registration strategy for multiple unlabeled point-sets of unequal cardinality, with no bias toward any of the given point-sets. To quantify the divergence between the probability distributions { specifically Mixture of Gaussians { estimated from the given point sets, one uses a recently developed information-theoretic measure called Jensen-Renyi (JR) divergence. The paper evaluates a closed-form JR divergence between multiple probabilistic representations for the general case where the mixture models differ in variance and the number of components. The paper derives the analytic gradient of the divergence measure with respect to the non-rigid registration parameters, and applies it to numerical optimization of the group-wise registration, leading to a computationally efficient and accurate algorithm.
287 days ago by IBM DownloadInnovative Design of Experiments (DOE) methods are used to significantly reduce the number of simulations required to model Biological Warfare (BW) attacks. The methods illustrated are applicable to almost any Modeling and Simulation (M&S) study involving large numbers of variables with many levels. The goal is to create a fast (seconds) surrogate metamodel of the simulation with which to make suitably accurate predictions of the response output for time consuming (hours) simulation trials not yet run. An example is shown that employs DOE methods that can be used when control variables are categorical and/or continuous. The analysis is based on a re-evaluation of data for all 648 possible combinations of settings of six variables in a BW attack case matrix completed for the military.
325 days ago by SAS Institute DownloadIn combination with compressive sensing, a successful reconstruction scheme called Curvelet-based Recovery by Sparsity-promoting Inversion (CRSI) has been developed, and has proven to be useful for seismic data processing. One of the most important issues for CRSI is the sampling scheme, which can greatly affect the quality of reconstruction. Unlike usual regular undersampling, stochastic sampling can convert aliases to easy-to-eliminate noise. Some stochastic sampling methods have been developed for CRSI, e.g. jittered sampling, however most have only been applied to 1D sampling along a line. Seismic datasets are usually higher dimensional and very large, thus it is desirable and often necessary to develop higher dimensional sampling methods to deal with these data.
346 days ago by Tsinghua University DownloadGood product design isn't about speed, it's about quality. With SolidWorks solutions and an Intel-based Dell Precision Workstation, small and medium-sized companies can now have both. That means knowledge workers can imagine quickly and transform ideas into high-quality products with exceptional speed. It also means that small and medium-sized businesses can be even more effective partners to their large, multinational manufacturing customers, who are increasingly looking to their partners to bolster their product development supply chain.
412 days ago by Dassault Systèmes DownloadThis paper purported to evaluate the anecdotal claims that 3D mice can significantly improve CAD design engineer productivity. Based on a survey of 190 3D mice users, substantial gains of more than 20% are being experienced by CAD design engineers while using 3D mice with their CAD applications. Underlying user interface research supported that 6DoF navigation and simultaneous two-handedness were two key factors leading to their improvements. Finally, it was shown that an investment in 3D mice can have an unusually fast payback - less than a month - leading to the 3D mice are in fact a "Smart Buy".
