Grabcad is CAD file online library. It remains some open source engineering communities. Grabcad is great project, with some undiscovered potential. This post presents some aspects of problems within engineering communities, developing engineering products using CAD software and Grabcad.
Three questions to Toshiko Mori. What stimulus perform on architecture? What are the main architectural challenges?
This post is a transcript from Dassault Systèmes blog entry. Dessault has deleted it for unknown reason. Fortunately I had this in my rss so I could copy it for you. Toshiko Mori explains the contemporary stimulus that are driving the architectural development. Globalisation and high demand on food access/living activities for thousands of people that are city inhabitants is the major factor that drives the architectural development so specifically as we see it today? Read a post because it’s interesting.
cadcammodelling.wordpress.com celebrates first anniversary of regular blogging. Some remarks are inside a post.
Post shows the computations that are needed in order to provide simple mathematical model while computing river dam. The computations can be used to verify the geometry (construction of river dam) in face of stresses and distortions so that the construction could be verified against natural construction conditions in pre-building simulation step.
Together with my friend I am developing avionics device for windows emdedded system CE 6.0. Read a post to get more info.
The posts presents my reflection about aspects of CAM, error compensation and materials. The example of submarine propellers is quite reasonable in it and facilitates following of article. Submarines are one of the most important weapon and therefore it’s worth reading about them. Some recent submarine disasters have been mentioned to show that we still have to develop our CAM tools and materials in order to produce better products.
The post presents selected applications of Fourier Transform with a short description. Telecommunication, automotive industry, medical industry, general IT, physical, geological, mechanical and military applications have been explained. The Powerpoint slides from the talk about guide on FFT numerical methods I gave at my university is available for download.
Numerical Methods for solving globally convergent nonlinear polynomial system of equations. Pathfinder part 1
There are many applications to solving a set of nonlinear system of equations problem in biology, economics, physics, engineering, geometry (intersection of surfaces) and of course mathematics and we have not found a numerical methods for solving it yet. Because of the existence of several roots, and that these usually are dispersed to unknown positions in N-dimensional space, efficient numerical methods are hard to develop. This posts presents three basics approach in solving this kind of problems and contains one simple example of kinematic chain that is helpful in general understanding of the main problem.
The post presents review of book “Fundamentals of Three-Dimensional Digital Image Processing” by Junichiro Toriwaki and Hiroyuki Yoshida I’ve prepared for my talk at my university. I have read this book and the review is part of report that is possible to read on my blog. Depsite the post doesn’t present the pure CAD/CAM content the 3D imaging has many application, I decided to publish it here and spend some time on reading this book. It’s a very interesting domain of knowledge and for sure 3D digital image processing is very important task with much more applications than in medicine.
3D Image processing. Report and Power Point presentation that describes the basics of 3D medical images
This post presents auxiliary materials to the talk I gave at my university about processing of 3D medical images. The rapid development of medical devices allowed for processing its results digitally. I am discussing the basic problems of image digitization and the process of creating 3D image. An survey about data structures and algorithms that plays major role in medical imaging has been published. The power point presentation, videos, and full text of report is available for downloading. It’s based on Fundamentals of Three-dimensional Digital Image Processing book by Springer.
