Big data for Medical

Big data is a game-changer for medical research. The ability to analyze vast sets of information, thanks to bigger and faster computers, is helping researchers to understand diseases, tease out genetic factors and spot patterns.

More researchers are looking at big data and understanding how we can utilize [it] in a better manner,” says Ervin Sejdic, assistant professor of electrical and computer engineering at the University of Pittsburgh, U.S., and founder of its Innovative Medical Engineering Developments lab.

In the past, clinicians would get data from patients and hold it up to metrics to try to see something by looking among different patient groups. “What they’re doing is flushing out the details. But the devil lies in the details,” Dr. Sejdic says. “The details are where we start understanding things. What’s really shifting in medicine is the fact that, yes, there is data, but let’s look at whole data sets.”

At the same time, better and smaller electronics, from smartphones to sensors you can wear, can compile more information at a detailed level and over bigger populations. “Researchers are looking at the interactions between different physiological systems. Sometimes these interactions break down in people with various diseases. Sometimes you have to look at the level of a minute, or an hour, or a day,” Dr. Sejdic says. “What big data is going to enable us to do is finally look at a human system as a system, rather than as individual components put together.”

Big data also is helping doctors and researchers to view diseases in shades of gray, rather than with a purely black-and-white outlook.

In the past, diseases were viewed in a simplistic way: a person is healthy or a person has disease. We would get specific information about the two states and compare the difference,” says Sergei Krivov, research fellow at the University of Leeds, U.K., who recently published research on the monitoring of kidney-transplant patients using big data techniques.

With transplants, he says, “There are two outcomes: perfect or problems. We are trying to find a single parameter to describe where you are between these two stages and what is the prognosis.” Based on the indicator, doctors can decide at an earlier stage whether to intervene into the process.

What I would like to see in the future is the following picture,” Dr. Krivov says. “A sizable part of the population frequently gives blood for analysis, for example during regular visits to their doctors. This would go to a data center. Based on this data for five or 10 years, we could determine indicators describing the degree of progression or the likelihood to occur for different diseases. We will give back this information as numbers, which is easy to interpret. This, in turn, will encourage patients to participate.”

One indicator patients might get with this approach is their biological age. “So you’re 30 years old, but your biological age is 20—or 40,” Dr. Krivov says. “Changes in your diet, exercise or lifestyle affect biological age. You might get younger, biologically. That would be reinforcement to the patient that he or she is doing well.”

DNA moleculeSome recent uses of big data include predicting the future of metabolic syndrome, advancing neuroscience, identifying dangerous pathogens, and conducting cancer research, among many others. DNA sequencing is getting cheaper thanks to big data, and genetic sequencing with big data is becoming a key part of epidemiology, because it helps trace chains of infection. Big data is helping researchers not only to understand the different genetic mutations in cancer, but also to personalize medicine: different mutations respond differently to treatments, and getting the right treatment straight away spares patients from side effects of treatments that aren’t effective for their particular kind of cancer.

However, challenges remain for big data to reach its full potential of analyzing many kinds of information from many patients. With computers, it’s “garbage in, garbage out,” so data needs to be structured to ensure consistency. Information often isn’t shared because organizations lack procedures or systems for communication. Advances in technology are helping to overcome some of those challenges, according to “The ‘Big Data’ Revolution in Healthcare,” a study by McKinsey & Co.

Big data is still a work in progress in medicine. “If a certain number of people have a disease, the task of searching for them will take minutes instead of days,” Dr. Sejdic says. “But for other things, it will still take days because you need to develop software first for analyzing the data.”

Too much data can be a problem, too. “When you know what you want to find out, it’s a much easier problem,” he says. “But if you’re looking for new patterns, it’s more of a fishing expedition. Whenever we do clinical trials, we are flushing out the details. There’s so much information that it’s hard to track it. Until we do that, we won’t have a good understanding. The major change will occur in the next 10 to 15 years.”

How to Stay Competitive? Develop Smart Appliances in the Era of Experience

By Estelle

Smart Home Device - Home Control

It is no secret that smart home appliances now are very complex.  No longer is a TV just a TV, or a refrigerator just a refrigerator.  Each smart home appliance needs to be digital, and it needs to interact with people or at least with other machines and devices.  It is connected to the Internet and has a variety of sensors.  It needs to collect data and give you more information, all the while lessening the need for you to actually do something to operate it.  You enter the room and your air conditioning is already up and running, keeping the room at an already comfortable temperature.  You drive up your block and your garage door opens automatically, while also turning on your lights and your TV to the channel that you always watch at that time of day.

It is no wonder IBM found that 71% of global CEOs(*)  now say that technology is the biggest external force that could impact their businesses within the next three to five years.  Most manufacturers now need to prove their competency by developing high technology products in order to stay in the competition. Otherwise, it will be your competitors who are going to give your customers the features and functionality that they want and need.

That is, of course, easier said than done.  In order to make smarter home appliances, you would need to have engineering proficiency in a wide array of areas such as software, mechanical, electrical, fluid, electronics, software, and other specialized areas.  It is not easy to excel in any of these fields, but having the knowledge is already a small part of your success.  You need to know how to bring all of these competencies together to meet what is required of your smart home appliances, as well as figure out what problems to solve and what technologies to use.

Today’s competitive manufacturer knows that looking at individual features and functionality is no longer enough.  You also need to focus on experience as well as product benefits.  Focusing on experience, you would need to know what your customers want to feel, to touch and to see, and how all of these affect their actions and emotions.

To stay competitive, you would also need to use big data to discover your customers’ preferences, even those that were not available before.  Then you would need to be able to translate these insights, experiences, and preferences into product attributes, such as energy consumption, usability, capacity and performance.

Once you know what attributes you would want your smart home appliance to have, you should be able to communicate these specifications to your design teams simultaneously and automatically.  This would mean that all your different design teams for software, mechanical design, electronics and other areas would get the attributes you need and want at the same time.

From there, you should be able to make trade-off decisions on how your design would be met by each of these design teams.  You should also strive to shorten your development time while ensuring that all your design needs are met, by using social collaboration tools and workflow.

And while work is in progress, you should be able to assess and monitor everything in real time.  Furthermore, you would need a virtual simulation of your products’ first prototypes.  This way, you would still be able to fine tune or revise everything that needs to be changed in your product design while still bringing down your development costs.

In short, traditional manufacturing concerns really need to transform their operations into high tech product development companies with the help of solutions such as Dassault Systemes’ Smarter, Faster, Lighter solution.  This way, you can transition into a more competitive and high tech manufacturing company by helping you define processes using established systems engineering principles.  These solutions also allow everybody working on the project to collaborate on your products, thereby making it easier to share knowledge and process that ultimately helps you produce a product that your customers will love.

Manufacturing Goes on The Cloud

By Tony

Cloud

The Cloud is Everywhere

Or at least it seems like the cloud is everywhere today. More and more you see service offerings to back-up your system data or store your files. The storage space is nice to have, but I like the cloud for the data organization aspects. Cloud storage lets you organize things like your music for example, according to many different criteria. So instead of just listing it alphabetically like I would on my hard drive, I can organize it according to the genre of music, or the year it was released. I can organize it according to whether I listen to it while I am driving or while I am working out. It also lets me grant access to it according to who may listen to it, so if it is a suitable song, I can grant access to my son or daughter so they may listen to it.  As my library of photos and music grows, as well as my family, I can add more space to the cloud to scale it to my usage.

Manufacturing on the Cloud Makes Big Data Easy to Manage

Manufacturing applications on the 3DEXPERIENCE® platform work much in the same way.  Of course the cloud offers a great repository to keep all of your manufacturing data and applications. But even better, it offers a great place to manage and access all of your project data.  Whether it is a document, a process plan, a workcell simulation, or a manufacturing resource, it can be easily accessible on the cloud from the 3DEXPERIENCE platform. 3DEXPERIENCE on the cloud makes large amounts of data manageable and makes it easily searchable by different criteria.

Manufacturing on the Cloud Offers Scalable Resources

Manufacturing on the cloud is scalable. Projects ramp up and down as do workloads. Companies have a tough time managing hardware and software requirements that are constantly in a state of flux. Once hardware is purchased, it is on the books until it’s lifecycle is over. On the cloud, software and hardware requirements are completely scalable. So as projects and workloads ramp up and down, so does the system utilization and software licensing. This means that the capital investment made for hardware and software is transferred to a scalable system. Over the years as the company grows, the value of the 3DEXPERIENCE on the cloud grows exponentially.

Manufacturing on the Cloud helps companies to be more competitive

The 3DEXPERIENCE platform on the cloud gives smaller companies many advantages. It provides scalable resources and technology at a lower cost. By hosting hardware and software on the cloud, it also allows for reduced on-site support from IT specialists, as well as reduced infrastructure. Since it lets IT offload the responsibility, your team can focus on new projects and new products. In other words, they can focus on growing your business.

There are many possibilities when manufacturing goes on the cloud. What do you think? To learn more, join in the conversation or visit our blog “60 Seconds to Experience”.
