Social Networks and Visualization

By Oleg

Despite summer relaxing time, I’m continuing to explore different dimensions of information visualization on 3D Perspectives. Social networks became a hot topic for the last few months or years and thought they can provide very interesting source of information to be presented in visual form. I decided to find a tool, I can use easy and in comfortable environment. So far, I found it…

Everybody likes Excel, right? So, let me show what is possible to visualize a social network using NodeXL (project developed by Microsoft Research). This application, so called .NetMap, can be used for viewing and analyzing of network graphs. Data can be prepared in Excel or imported from any applications. Use this link to download detailed presentation of NodeXL. You can download NodeXL code from Codeplex.

You can ask me, if I see any connection to word of Product Lifecycle Management? Yes, I do. The power to visualize and graphically represent information, solutions, ideas in multiple dimensions, as well as manipulate and collaborate with others is the next big revolution in technology. Since PLM is making social turn and focus on people, I think visualization of social communication together with 3D product visualization can provide very powerful turn in development efficient 3D Social Network Collaboration Tools.

Best, Oleg.

Better, Faster, Smarter CPG Innovation

By Rosemary

Maintaining financial viability while delivering innovative, environmentally-sustainable products may be the most important business issue confronting Consumer Packaged Goods (CPG) companies today.

Faced with a global recession, ever-changing consumer preferences, and higher development costs, CPG leaders want solutions that provide Better…Faster…Smarter innovation.

Leading CPG companies are finding success deploying Product Lifecycle Management (PLM) practices. As a strategic pillar for creating business growth, PLM enables:

Better innovation while providing open, yet directed collaboration across the enterprise, and with consumers and suppliers

Faster innovation through efficient use of internal and external resources and repeatable phase-gate processes

Smarter innovation by efficiently capturing and re-using intellectual property (IP) and value chain capabilities throughout the product development process

PLM practices drive organic growth by linking a company’s innovation engine intrinsically to its business strategy and empowering management.

“How do we develop new, successful, and environmentally-sustainable products, at a competitive price, and increase profitability at the same time?”

Stay tuned! I’ll be tackling this question in a blog series over the coming weeks . . .

Best,

Rose

How Do You Mend a Broken Heart?

While I know that I should eat well, exercise regularly, not smoke, and have regular checkups – I don’t always do these healthy things, which puts me at greater risk for developing a heart condition. 

Apparently, I am not alone. I just read some staggering statistics on Heart Failure (HF) at the US Center for Disease Control and Prevention’s website. Five million people in the United States suffer from HF and 500,000 more are expected to join their ranks each year.  According to the American Heart Association (AHA), the 2006 costs associated with HF in the U.S. was 29.6 billion dollars.

Thankfully, there are many bioengineering researchers in the world who are using realistic simulation technology to study the heart and associated medical devices in amazing levels of detail.

Performing realistic 3D simulation of the human heart and medical devices requires being able to model human tissue, blood flow, nonlinear structures, and complex contact between the devices and the heart. SIMULIA has developed robust finite element analysis (FEA) and multiphysics technology within the Abaqus Unified FEA product suite.  This technology is being used by bioengineering researchers to simulate realistic physical behavior of the medical devices interacting with the heart, arteries, and blood vessels.

One of those researchers is Dr. William Peters, a cardiothoracic surgeon and and founder of Sunshine Heart in New Zealand. His patented C-Pulse has recently been accepted for human trials in the U.S. The device consists of a cuff that wraps around the aorta that inflates and deflates a membrane against the vessel’s external walls. This process makes the aorta pulsate in time with the heart, augmenting blood flow through the circulatory system and reducing the strain on the entire heart. Check out the complete case study here.

Milton DeHerrera Ph.D of Edwards Lifesciences  is another innovative bioengineer. At the 2009 SIMULIA Customer Conference, he presented a paper on the “Numerical Study of Metal Fatigue in a Superelastic Anchoring Stent Embedded in a Hyperelastic Tube”, coauthored by Wei Sun, Ph.D from the Department of Mechanical Engineering at the University of Connecticut. Their research is intended to  improve the virtual representation of human tissue and medical device interaction.

Adding to the complexity of developing medical devices is that ‘one-size does not always fit-all’. Dr.   Ken Perry has a cool medical device simulation blog site detailing his use of FEA and associated validation processes. Check out a couple of his recent posts – Identifying Worst Case Device Sizes and FEA and the FDA .

These dedicated researchers are helping to develop amazingly innovative and effective treatments that are truly capable of ‘mending broken hearts’. Now that I am aware of the alarming heart failure statistics, I plan to take a little more initiative in trying to keep my heart healthy.

Pass the fruit, veggies, and oats…will you join me?

Take care
Tim

PS: This is part 2 of my ongoing series on how realistic simulation is being used to improve medical devices and enhance the quality of our lives, stay tuned.
