Healing Broken Hearts on Valentine’s Day

By Kate

In honor of Valentine’s Day, a time when people celebrate the love in their lives, I’ve got a kind-of related blogpost to share.  We’ve must literally take care of our hearts in order to be around for those hugs and long-stem roses . . .    

Tim’s post focuses on “dedicated researchers [that] are helping to develop amazingly innovative and effective treatments that are truly capable of ‘mending broken hearts’.”  And they’re using realistic simulation software to do it.

And Happy Valentines Day !

Khufu’s Secret Rooms

By Kate

The Great Pyramid of Giza is not only in Egypt.  It’s in the classroom, our dreams, picture frames, and even the Parisian metro.   But do we really know it? 

Today thanks to an architect and 3D scientific simulation software, I feel like I know Cheops better. 

Building on his internal ramp for construction theory, Jean-Pierre Houdin thinks he has cleared an intuitive itch that something was missing. And his friends Mehdi Tayoubi and Richard Brietner from Dassault Systèmes have helped him do it. 

Most people believe the King’s Chamber was closed from the inside.  But then that would have left a dozen workmen corpses with the deceased.  No skeletons other than the king’s were found in the chamber.  Jean-Pierre believes the room was closed from the outside, through a passageway that has never been physically located or explored.  A passageway that leads to the two funeral antechambers.

What funeral antechambers!? 

It’s true that when I was in 5th grade and made a foam bisection of Cheops, the result looked something like this:

Note the only places indicated are the King’s Chamber, Grand Gallery, Queen’s Chamber and Unfinished Subterranean Chamber. 

Jean-Pierre had the genius idea to study how Khufu’s father designed and built his burial place, the Red Pyramid.  The day his father died, Khufu needed to start planning for his own pyramid.  So it’s logical to think Khufu hired the same architects who’d acquired solid expertise by building his father’s.  And the Red Pyramid contained evidence of something not thought to be associated with Khufu’s: two funeral antechambers and their corridors.

The funeral corridors and antechambers were necessary to carry in and stock furniture and ritualistic objects employed during the ceremony.  Impossible to predict when the king would die, they needed to have everything in place before death. 

The locations of the antechambers, just beside the King’s Chamber, were logistically strategic for slipping the items into the King’s Chamber for the ceremony.  After the ceremony they were moved back to the antechambers, and from the joining corridor, the last granite stone was placed, enclosing the king in the afterlife, forever. 

How did Jean-Pierre verify his theory? 

Only physical proof would provide conclusive evidence, but I was persuaded by the software simulation. 

By taking the same antechamber architectural elements and dimensions from the Red Pyramid and including them in the Cheops 3D model, Jean-Pierre, Richard and Mehdi found answers to questions.  For example, the peculiar twists and directions of the already-explored corridors are justified because they are avoiding the antechamber components. You can see these in the French language news video here (great 3D footage).

While I learned many other interesting things today, this tops my list.     

Were the Egyptians so focused on the afterlife that they forgot to pass down the knowledge of how real-life royal funerals were performed?  You know, the “boring” logistical details. 

Do the Cheops antechambers still contain the furniture and objects used to perform Khufu’s funeral? 

I’d like to find out, wouldn’t you? 

Best,

Kate

P.S.   This morning’s conference presented a lot to digest, and all kinds of fun anecdotes and information to share.  Stay tuned . . .

Professor Plum with the Wrench? Abaqus FEA Knows

By Tim

No, it’s not the famous game “Clue”. It’s the use of realistic simulation to perform forensic studies of skull fracture.

While, for the average person it is a bit gruesome to think about, medical examiners and police investigators are often faced with the need to determine how and why skull fractures occur.

Was the head injury caused by an accident or was the injury caused with the intent to murder the victim?

Researchers at the Institute of Forensic Medicine at the University of Copenhagen, in cooperation with the Technical University of Denmark (DTU), are using using technology from Simpleware (a SIMULIA partner) to transfer CT-scan data into SIMULIA’s Abaqus FEA software.  This allows them to gain a deeper understanding of the mechanics and forces that cause severe skull injuries.

While the researchers consider their current studies as preliminary, these represent a critical step on the path to developing a general tool for supporting medical examiners with easy, achievable and accurate numerical simulation to support their judgment regarding the cause of death.

To get more details, check out the complete case study in the latest issue of INSIGHTS magazine  here.

Are you as surprised as I am that Abaqus FEA software (traditionally used to study the performance of mechanical systems in cars and airplanes) is being used in forensic head injury research?
