Professor Matheron’s take on random functions

Once upon a time Professor Matheron talked about Brownian motion along straight lines. He did so during his own presentation at the colloquium on Geostatistics at the University of Kansas on June 7-9, 1970.  Matheron never got into counting degrees of freedom. Incredibly, the Creator of Geostatistics aka the Founder of Geostatistics did not know how to test for spatial dependence between ordered sets of measured values! His PhD supervisors could not get the Creator of Geostatistics test for spatial dependence between ordered sets of measured values. All it would have taken is apply Fisher’s F-test  to the variance of a set of measured values and the first variance term of the ordered set.

So who has always believed that Geostatistics is a valid science? It was Dr Frederik P Agterberg.  He had put together Geomathematics, Mathematical Background and Geo-Science Applications. An expert at Elsevier Scientific Publishing Company had called it Developments in Geomathematics 1.

Who created geostatistics?

Professor George Matheron did! How many geostatistocrats knew that he was the mastermind behind  the novel science of geostatistics? Dr Frederic P Agterberg was another mastermind. I’ll need more time to report what he has been writing. Of course, it makes no sense to krige, smooth and rig the rules of applied statistics with impunity! Invariably, I test for spatial dependence between measured values in ordered sets by applying Fisher’s F-test to the ratio between the variance of the set and the first variance term of the ordered set! That’s why applying the F-test makes sense. The more so because Dr Roussos Dimitrakopoulos is not yet teaching his students at McGill University why degrees of freedom ought to be counted! Professor Dr Michel David had been awarded Grant 7035 by the National Science and Engineering Council of Canada. Good grief! Why does NSECC not respond to questions?

Oversmoothing small blocks?

Why did Dr Roussos Dimitrakopoulos get into stringing Markov chains between measured values? He may have done so because he did not want his disciples to know how to test for spatial dependence between measured values in ordered sets! Neither did Dr RD want his disciples to know how to count degrees of freedom. Sir R A Fisher has been teaching in Australia why degrees of freedom ought to be counted. Dr RD has studied in Australia but does not teach his disciples that degrees of freedom ought to be counted! Even NSERC/CRSNG does not care that Dr RD ignores degrees of freedom while stringing Markov chains between too few measured values.

Playing with Fire? A Guide to Fire Retardant Conveyor Belts

September 2014

If a belt does not perform according to the manufacturer’s claims by wearing prematurely, ripping too easily, disintegrating due to excessive heat or because of oil penetration, the risk to life and limb is relatively small. But if a conveyor belt that is specified as being fire resistant catches fire but does not resist the fire the way that it should do then it will literally ‘convey’ the fire throughout the site. The consequences can be catastrophic.

 

Is cost being put before safety? 

Due to the financial pressures, more and more organisations are being forced to examine their day-to-day running costs and, almost inevitably, seek cost savings. The pressure to cut costs seems to be influencing buying decisions concerning fire resistant conveyor belts but is price being put before safety? The discovery that a belt is not sufficiently fire retardant is only likely to be made when it is too late.

The New Bulk-Blog

Dear Bulkoholics,

As you may have noticed, we are presently upgrading our bulk-online system and our front page, and in this context we will also put more emphasis on the Bulk-Blog. We intend to invite major companies, institutions, organisations and publications to present their News. By doing so, we will offer them a platform on the worldwide leading Powder/Bulk Portal. This should be of interest to them and it will certainly be of interest to our many readers and users around the world.

Should you be interested in using this plattform, please post your message/comment here or write to wohlbier@bulk-online.com.

I am very excited about this new development and believe that it could be of considerable value to our members.

Reinhard Wohlbier

 

Unscrambling the French sampling school

Dr Pierre M Gy (1932- ) threaded together the theory and practice of sampling particulate materials. Gy’s gift to mankind ended on my desk about Christmas 1979. I had never ordered it! Yet, Gy’s invoice had come along with his work. Elsevier Scientific Publishing Company had printed it as Sampling of Particulate Materials, Theory and Practice. It had done so as Developments in Geomathematics 4.

Elsevier has ranked Dr F P Agterberg’s Geomathematics as Volume 1 in this series. Dr M David’s Geostatistical Ore Reserve Estimation was ranked as Volume 2. I kept track of what Elsevier Scientific Publishing Company had deemed fit to print before 1979. I am keeping my favorite textbooks close together. William Volk’s Applied Statistics for Engineers is my favorite. Of course, Volk’s work ought to be studied in detail. Degrees of freedom should be counted whenever unbiased confidence intervals and ranges for contents and grades ought to be reported!
