Finite Element Analysis: Post-processing

The following four-article series was published in a newsletter of the American Society of Mechanical Engineers (ASME). It serves as an introduction to the recent analysis discipline known as the finite element method. The author is an engineering consultant and expert witness specializing in finite element analysis. FINITE ELEMENT ANALYSIS: Post-processing by Steve Roensch, President, Roensch & Associates Last in a four-part series After a finite element model has been prepared and checked, boundary conditions have been applied, and the model has been solved, it is time to ...

Wind Energy: Umm Leads The Way For American Universities

In March 2005, the University of Minnesota-Morris became the first public American university to install a large-scale wind turbine to help meet the school's electrical needs. Since it was installed, the generator has supplied some 60 percent of the university's power. The rest of the school's power needs are purchased from Otter Tail Power Company's Tailwinds Program. Those figures mean that whether the electricity is generated on site or purchased off the grid, 100 percent of UMM's electrical power needs are supplied by wind power, but the school's ...

Chandrayan I

It was on July 20, 1969 that "Eagle", the lunar module landed on the moon and American Astronaut Neil Armstrong took "that one small step" paving way for "a giant leap for mankind" . In 2007-08, India will launch Chandrayan I, which will be closely followed by China's CHANGE-I. Indian Space Research Organization (ISRO) is spear-heading all the activities in the field. Chandrayan I, India's first unmanned mission to moon was announced on August 15, 2003. The Chandrayan I mission envisages placing a 525 kg satellite in a ...

On the Nature of the Nazca Lines

In my prior posting, entitled "Ancient Astronauts and Contemporary Skepticism," I challenged the skeptics (assuming they do not want to acknowledge that the Nazca Lines were made to be viewed by an ancient astronaut) to provide a credible explanation of those geoglyphs. I argued that the people of Nazca cannot be considered unique in human history and that the skeptics need to find parallels elsewhere. However, I imagine that, instead of trying to produce a mundane explanation of the Nazca Lines, the skeptics could simply argue that I ...

Talk About Hidden Costs…Technically Speaking

7:47 PM 4/24/2006 Author: Lucien Beauley Lighting Facts...I Wanna Know ! Each one of us, at one time or another has either driven or been a passenger in an automobile and experienced our traffic control lighting system. Originally unique, but now part of a global system. Situated at every fully functional traffic light intersection is at least one "Red" light which is timed to turn on and off regularly to "Stop" traffic. It employs a 100 Watt(varies between 90 and 120 Watts)incandescent light bulb. Several years ago, these ...

What is Occam’s Razor? By Wally Jukes

Occam's (or Ockham's) razor is a principle named after the 14th century mathematician and friar, William of Occam. Ockham was the village in this English County where he was born. There are many resources to investigate this man and his theories. This is not about him but his thinking. Thinkers are important to the world. Over thinking something can be the death of it. Most people have never heard of this and yet with the logical thinkers of today it is almost built into our genetic code. We ...

Rishon Model of Elementary Particles

It has been proposed that the quarks and leptons consist of more fundamental particles called rishons. The T rishon may be defined as having mass and charge e/3. The V rishon is neutral and has little or no mass. The rishons have spin 1/2, carry color charge, and combine in triplets or rishon-antirishon pairs. Thus the electron is a TTT, the neutrino VVV, the down quark TVV, and the up quark TTV. If the T has somewhat greater color charge than the V, the down quark would have ...

Foam – Just what on earth is it?

Just what on earth is foam? It is a question that has plagued mankind for centuries. Well, alright, maybe not. Nevertheless, foam has long been a mysterious material, yet useful in many ways, not least for insulation and packaging. Put simply, foam is plastic that has been melted, had bubbles of gas forced into it, and then been left to re-form. This produces a cheap, soft, spongy material, which can then be sliced into specific shapes or simply minced up into pellets. The kind of foam you’re probably ...

E=mc2 is Wrong

Is Albert Einstein's Special Relativity incompatible with the very equations upon which science's greatest theory is built? New observations made by many scientists and engineers appear to contradict the great scientist's ideas. Apparently there are implicit contradictions present within Relativity's foundational ideas, documents and equations. One individual has even pointed that quotations from the 1905 document and Einstein's contemporaries as well as interpretations of the Relativity equations clearly and concisely describe a confused and obviously erroneous theory. It is time therefore, for science to update its thinking on ...
