In the broadest sense, it is a measure of our lack of understanding. This is difficult: it is easier to list what we know than what we don’t know. The quantification part points to a scientific approach to the problem that involves axioms, definitions and rules. Uncertainty quantification is both prescriptive and normative: a set of rules on how to proceed are created based on mathematics and logic, in particular, probability theory and statistics. Within those rules, calculations are done that involve observed data as well as global understanding of the subsurface system created from experience. Thus, it allows making optimal decisions even if we cannot perfectly predict the outcome of the actions we take in the exploration, appraisal and development of subsurface resources.
Be it designing, analysis visualisation is a big part of engineering discipline. Such is it’s important that entire industries are based on providing physics based softwares.
But now we have a new toolkit to understand the complex behaviours of fluids and other. Neural networks are able to learn the patterns of smoke simulation etc without any pde’s. This is going to be a huge step in the industry.
Watch the video.
Can’t wait to see this technology to come to production.
For me 2011 was similar to 2017. Back then I rekindled my painting and did few paintings for some weeks. All those paintings are long gone but I remember few of them because they have survived as Facebook posts.
So here are few more that I did last month.
During October last year, my work involved using HDF library with FORTRAN and C and use them to store mounds of data other systems were generating.
The first step was to use the library with visual studio 2008 in windows. Companywide HDF5 had many users in Linux cluster but no formal implementation was available to use in visual studio. While that made the library available but building, a program using them in visual studio was a different matter. I faced couple of issues and with much googling and stack overflowing, solved them, here is the running note I took for one of the issue, just in case someone else is in the same situation.
Hope this helps.

The various header files associated with the visual C++ runtime embed a number of directives into the compiled code. This power used to be used for good: appropriate #pragma’s could ensure that the resulting .lib file automatically had a dependency on the correct runtime libraries.
However, a kind of dependency ____ comes about when one tries to mix projects built with different build settings in the same version of dev studio, and becomes even worse when pre-built libs made by another version of Dev Studio are used.
The best thing to do, frankly, would be to rebuild your .libs in the same version of Dev Studio. There are some project settings that can be used when building a .lib that can ‘sanitize it’ a bit and make it’s use more compatible with different versions of dev studio – libraries should generally be built with the multi threaded runtime selected (NOT the DLL runtime) and the option “Omit Default Library Names” selected.
In this case, __forceCRTManifestCUR, is a result of a #pragma comment(linker, “/INCLUDE=__forceCRTManifestCUR”) directive in one of the c-runtime header files.
You can work around this by simply including a like like this in your main.cpp file:
Doing this will “defeat” an attempt by the headers to get a manifest dependency to the “current” version of the CRT dlls embedded – but don’t worry – the correct CRT manifest is already specified correctly using a different mechanism, so you can generally quite safely define this symbol (by declaring it as an int or anything really) without causing any problems for the project.
In 2016, I read close to 75 books. In 2017, the goal was to read half that much and I managed to do more. Thanks to the 3 mile daily commute to office. Don’t know about the waistline, but brain really did get some exercise during those walks. I love these walks. This is one thing will miss the most when I get back.

I guess this will be one of the regular feature of the blog. Paintings.
Here are some I did over last few days.
Practising this with small or any canvas that I get by.
