			<content:encoded><![CDATA[<p>A lot of you are either finishing up school for the semester or just finishing school. Either way a lot of you are probably starting to ask yourselves “<a href="http://www.youtube.com/watch?v=4flkRAgWuVE">What’s next</a>?.” <span id="more-8096"></span>The transition from a school to a work environment can be a little intimidating, but rest assured it’s a good one and being an engineer doesn’t mean you have to be stuck in a cubicle or relegated to menial tasks.</p>
<p>Now, I’ll grant you, there are some who will wind up lining under the soft glow of neon bulbs and spend their days checking plans and/or editing others work. Chances are many of you won’t even use a large portion of that fancy new degree you’ve spent so many sleepless nights pursuing. These are the unsung heroes of the engineering world. They won’t ever get profiled in fancy online magazines, they won’t ever get rich, but they will be a driving force in the engineering world. These are the engineers who get our roads built, they get our shipping containers designed, they make sure water and sewage systems that service millions function properly, and they even make sure your keyboard keys have just the right amount of “click”.</p>
<p>But even those with the most boring engineering jobs now get to stretch their design and manufacturing wings. Right now the engineering field is undergoing a grassroots overhaul. What used to only be possible by huge companies is now being done by individuals with talent and vision; sometimes even in their own garages!</p>
<p>We are entering the era of the one person engineering team.</p>
<p><a href="http://why.knovel.com/knovel-for-engineers/what-is-knovel-for-engineers.html">You research it.</a></p>
<p><a href="http://usa.autodesk.com/adsk/servlet/pc/index?id=20884205&amp;siteID=123112">You design it.</a></p>
<p><a href="http://cubify.com/cubex/">You test it.</a></p>
<p>You are the engineer.</p>
<p>Of course weekend inventors have always existed, but now people with the right education and mindset are able to move beyond garage tinkering and become truly independent. So now it doesn’t matter if you’re stamping blueprints for a 40 year old roadway or scuba diving off an oil rig, when we get home and take off our ties (or snorkel) we now are on equal footing.</p>
<p>It’s a great day to be an engineer.</p>

			<content:encoded><![CDATA[<p>It seems that everywhere I looked the past few days it seems I see something about private space travel and visiting other planets. This tickles my black little heart to no end, however it does make wonder: Are we seeing a space bubble starting to form? I’m worried we are and here’s why:<span id="more-8089"></span><br />
<strong>Transportation</strong><br />
A lot of people who are interested in getting to LEO and beyond are hitching their wagons to the SpaceX Falcon9 Heavy. Now don’t get me wrong; SpaceX is an amazing company and I really believe that they will build what they’ve shown us and that it will perform as expected.<br />
With that being said, they still haven’t built it and it is entirely possible it may never get built. These companies really need to have some sort of backup plan or at least consider the risk of only using a single launch vehicle. At this point, if SpaceX fails, so will everyone else who is planning on using their products.</p>
<p><strong>Hardware</strong><br />
Everyone is talking about using hardware that hasn’t been developed. Heck, it hasn’t even been designed yet. Conceptual art is fun to look at and send the imagination into overdrive, however it’s a bad sign when a company dismisses the idea of building an actual product and simple states “someone else” will do it. If you look at other capsules that are just now starting to be tested in space you’ll see they’ve been in development for years already. The fact that there are more rocket builders than habitation builders should tell you right away we aren’t ready for any kind of space exploration beyond LEO.</p>
<p><strong>People</strong><br />
Not only is our hardware ready, neither are the people we are going to be sending into space. Astronauts are people who have trained for years in state of the art facilities in programs that have been around for decades. You don’t just go out and hire someone off the street and send them to astronaut school. The idea that “married couples” or “rich people” or “people who register at our website and pay a small signup fee” is borderline insanity.</p>
<p>There are a limited number of astronauts. Not every astronaut in existence is going to want to work for a private company.  Many astronauts do not have the experience to lead/babysit non-astronauts. As you can see this means there is a rather small hiring pool of qualified candidates. The fact that there are no astronauts who have stepped up and announced they are working for a private company should be telling in and of itself.</p>
<p><strong>Conclusion</strong><br />
We are not ready to go exploring. It’s not for a lack of will, or money, or even grass roots support, because I really think all three of those things exist. What we do not have is a existing means of launching, no hardware even on the drawing board to support crewed missions beyond orbit, and even if we did we don’t have people qualified to participate and lead such missions. So let me reiterate: Getting the public excited for trans-planetary missions is a good thing, it builds grassroots support and keeps space in the public eye. However we do need to be careful that we aren’t accidentally leading people to believe that we are more prepared than we actually are.</p>

<p>In Gravity, two astronauts (played by Sandra Bullock and George Clooney) are stranded in a deserted space station with no communications with Earth. The trailer gives you a glimpse at the drama of their fight for survival while lost in space, and at Knovel&#8211;we&#8217;re definitely excited to see how this sci-fi thriller concludes.</p>

			<content:encoded><![CDATA[<p>Despite what customers and bosses sometimes ask for, all of our engineering solutions are bounded by rules. Whether it&#8217;s the laws of physics, company politics or something else, there are always rules. <span id="more-8060"></span>We don&#8217;t approach every problem with a truly clean slate. In fact, we don&#8217;t ever approach any problem with a clean slate. For me, that&#8217;s what makes engineering interesting. It&#8217;s part of <a href="http://www.knovelblogs.com/2012/09/13/are-you-an-engineer-or-a-scientist/">what distinguishes engineering from science</a>. Managing complexity and reaching solutions, whilst staying inside the boundaries and knowing when to stop. It&#8217;s all in a days work for an engineer.</p>
<p>Having said that, there is still a lot of room for creative freedom in engineering. Even though a lot of the problems we solve may be similar to those we&#8217;ve solved before, the solutions don&#8217;t have to all look the same. With every set of rules and constraints, a different set of solutions becomes possible. The real skill comes first in knowing all of the constraints and then coming up with a solution which elegantly and efficiently navigates between them.</p>
<p>Gaining a solid understanding of science is a great place to start. After all, the vast majority of scientific principles will remain constraints on our solutions for a while yet. Recently, an initiative by the British Science Association to find the best classroom science demonstrations caught my eye. They&#8217;ve compiled a series of short videos (of which I have watched far too many), each explaining or demonstrating a scientific principle. There are some &#8220;old favorite&#8221; experiments in there, and some were totally new to me. It really is quite impressive what can be done with some basic kit and a little scientific knowledge.</p>
<p style="text-align: center;"><strong>Here are three of my favorite demonstrations:</strong></p>
<p style="text-align: center;"><strong>1. Amazing Sound and Water Experiment</strong><br />

<iframe src="http://www.youtube.com/embed/PuiPDBA3XZI" frameborder="0" width="480" height="360"></iframe></p>
<p style="text-align: center;"><strong>3.  Conducting Glass</strong><br />

Knovel was acquired by Elsevier in December 2012 and is part of Engineering and Technology Markets group managed by <a href="http://www.knovelblogs.com/2013/05/08/knovels-new-chapter-a-qa-with-ella-balagula/" target="_blank">Senior Vice President Ella Balagula</a>. . .<span id="more-8044"></span><a href="http://www.knovelblogs.com/wp-content/uploads/2013/05/311f518.jpg"><img class="alignnone size-full wp-image-8046" title="Chris Forbes" src="http://www.knovelblogs.com/wp-content/uploads/2013/05/311f518.jpg" alt="" width="200" height="200" /></a>Over the last several months, I’ve watched the Knovel team work hand-in-hand with their new Elsevier colleagues. It’s clear that we’ve found a perfect home to grow our business, and being part of a global company with employees in 20+ countries, offers our employees tremendous opportunities for professional growth.</p>
<p>While I had support from Elsevier’s management team to find a good fit within Elsevier, I’m an entrepreneur at heart.  My highest calling is to develop good ideas into scalable businesses – exactly what I was able to do at Knovel, with the help of a great team. And I do want to acknowledge the contribution of everyone on the team – you’ve done great work.  I’ll miss doing the work with you, and I am sure you will continue to do great work. I also want to acknowledge our customers who have graciously shared their time and insights with me over the years.</p>
<p>Together, we have made Knovel the trusted brand for delivering answers that engineers can rely on. Knovel enjoys this strong reputation because of our focus on high-quality content, engineering-focused search and engineering-specific tools. Being part of Elsevier strengthens our ability to continue to grow and offer our customers more.</p>
<p>I’d like to leave the Knovel team with one thought that has become the essence of my business philosophy: trust. Trust has been at the heart of the Knovel culture. We believe in integrity, intent, ability and results. I put my trust in Elsevier, and their ability to continue to meet the diverse and ever-evolving needs of our engineering community.</p>
<p>Thank you for your trust in me over the years.</p>

<p><em></em> <a href="http://www.knovelblogs.com/wp-content/uploads/2013/05/070a818.jpg"><img class="size-full wp-image-8041 alignleft" title="070a818" src="http://www.knovelblogs.com/wp-content/uploads/2013/05/070a818.jpg" alt="" width="199" height="199" /></a></p>
<p><strong>Q) Can you tell us a little about yourself? What lead you to your career at Elsevier?</strong></p>
<p><strong>A)</strong> I have always had a great affinity with science and technology – my undergraduate degree is in mathematics. I was a computer programmer for a few years before getting my MBA at MIT Sloan’s School of Management. My strategic expertise and broad business experience was built upon seven years in management consulting at A.T. Kearney. So it was quite fitting and lucky that my science and technology interests found a home in a business setting at Elsevier, managing our Engineering &amp; Technology Markets business unit.  I am passionate about our products that focus on improving outcomes for our customers and users in R&amp;D intensive industries by bringing together world class content and enhancing it with the latest technology innovations.</p>
<p><strong>Q) You were an early champion of acquiring and ultimately integrating Knovel. What was it about Knovel that sparked and kept your interest?</strong></p>
<p><strong>A)</strong> On a personal note, my mom was an electrical engineer – not a small feat for a girl in the 1960s Russia – and her choice of profession always inspired and fascinated me.  At Elsevier, when I considered all of the corporate customers and markets that Elsevier serves, it became apparent to me that engineers had a presence everywhere: every large and small company, in every industry, in every discipline.  The engineer is at the heart of any application of technology used to improve a process or product.</p>
<p>I met Chris Forbes for the first time in 2007, and the fact that Knovel studies, understands, supports, and improves the outcomes for this essential audience convinced me that the company was on a special path.  Together with our Engineering Village, <a href="http://www.sciencedirect.com/" target="_blank">Science Direct </a>and <a href="http://www.scopus.com/" target="_blank">Scopus</a> offerings, we’re able to serve scientists and engineers across the complete spectrum of research, development and applied engineering activities within organizations.</p>
<p><strong>Q) What’s going to change with you at the helm of Knovel?</strong></p>
<p><strong>A)</strong> The Knovel team has invested a large amount of time and effort to make Knovel what it is today, so most of the changes that may come will be small ones that add new features, new content or other means to enhance the experience for our customers by taking advantage of Elsevier’s resources. I fully intend to maintain Knovel’s leading position through its core components of high-quality content, engineering-focused search and engineering-specific tools, bringing us even closer to end-users and customers and making Knovel easily accessible in the international markets.  I see Knovel as a keystone business that will anchor our growth in the Engineering market.</p>
<p><strong>Q) How do you stay on top of industry trends?</strong></p>
<p><strong>A)</strong> I read the “Economist” to stay close to macro R&amp;D trends affecting our customers. I find Outsell daily insights and industry reports very helpful to stay on top of the information management industry. The Engineer magazine gives me insights into the latest developments and challenges in the engineering disciplines across industries.  And finally, nothing is as effective as talking to our customers, whether through individual visits, or attending conferences and trade shows.</p>
<p><strong>Q) What trends are you watching most closely with our business in mind?</strong></p>
<p><strong>A)</strong> I think the explosion of growth in Asia is transforming all aspects of our business. The unprecedented economic growth has resulted in China and India combined, surpassing the US in R&amp;D spend, in the number of scientific and engineering graduates, in the academic peer-reviewed published output, and in the number of patent applications. This shift in global information demand presents great opportunities for our Elsevier products and especially for Knovel.</p>

			<content:encoded><![CDATA[<p>Even the longest standing technologies eventually have to move over to make way for new innovative solutions. It can sometimes take a while though, since the transition only comes about when the improvement on offer is big enough to outweigh the inconvenience of moving away from a tried and tested solution.<span id="more-8031"></span>Although many of us like the idea of &#8220;new&#8221;, we&#8217;re often reluctant to give up the safety and security we find in our habits and routines (does anyone remember when Microsoft introduced the ribbon?).</p>
<p>Well this time, it could be the turn of the QWERTY keyboard to move over. It&#8217;s faster, more functional younger brother is starting to make waves and could spell the end of QWERTY.</p>
<p>The KALQ keyboard has been designed with touch screen typing in mind. With so many people using their thumbs to type on smartphones and tablets, a research team set out to improve the keyboard layout to help users type faster and more accurately. Researchers from the University of St Andrews, the Max Planck Institute for Informative and Montana Tech have jointly designed a new keyboard which allows users to thumb-type 34% faster on tablets than they can using a QWERTY keyboard.</p>
<p>This isn&#8217;t the first time the QWERTY keyboard has been challenged. Since the layout was developed in the 1870&#8242;s for use on typewriters there have been many alternatives proposed, each boasting their own improvements. So far though, there hasn&#8217;t been an alternative which offers enough of an improvement to take the top spot away from QWERTY.</p>
<p>Dr Per Ola Kristensson, a member of the research team from St Andrews, said &#8220;before abandoning QWERTY, users rightfully demand a compelling alternative. We believe KALQ provides a large enough performance improvement to incentivise users to switch and benefit from faster and more comfortable typing.”</p>
<p>The optimized KALQ keyboard places all vowels in an area around the right thumb, while consonants are mainly grouped around the left thumb. The aim of this is to allow the user to alternate the thumb used to type each letter.</p>
<p>The team intend to make the KALQ keyboard available as a free app for Android-based smartphones. Do you think it&#8217;ll have enough to take the place of QWERTY?</p>

			<content:encoded><![CDATA[<p>So I’m sitting here, in my office, staring at a blank page where my post should be, with a crying baby in the next room on my birthday. I’m tired and feeling old. I’ve been out of school longer than I’ve been in it and sometimes feel like I’ve forgotten everything I had learned. In short I’m feeling like I’ve forgotten where and what I should be doing. SO I do what I normally do when I feel like this: Surf the web for cool videos.<span id="more-8012"></span>Funny cats – Meh</p>
<p>Stupid human tricks – No thanks.</p>
<p>And then I see it.</p>
<p><a href="http://www.space.com/20779-spacex-grasshopper-jumps-again-and-the-view-is-terrific-video.html" target="_blank">THIS</a>!</p>
<p>It’s not a very flashy video. Indeed, an uneducated person might not see anything remarkable. But to my old and fading eyes I see something brilliant; something beautiful. SpaceX, my eternal BFF launched a rocket over 800 feet and landed it back vertically!<br />
Now I could tell you young kids how back in my day we used to drop our rockets in the ocean when we were done with tem, and how these kids today(and their “rock and roll”) don’t know the first thing about rockets… But holy cow these guys are just making everyone else look bad! It’s like SpaceX is saying “Sure we COULD just launch a rocket, but let’s make it interesting and set it back down on its flight pad when we are done with it.”<br />
They’re essentially calling out the rest of the space industry. They aren’t writing papers, they aren’t trying to get money from the internet; they are going out there and getting it done just like in the good old days of space flight.<br />
Watching that rocket come back down was like Kirk watching the Genesis Planet. I feel young, I feel good. Maybe we are getting smarter at this whole rocket thing and we something to show for it.</p>

			<content:encoded><![CDATA[<div id="engcase">
<div class="entry">
<p>Although parts inspection is a complex business driven by the ever-increasing complexity of manufactured goods, it has stuck pretty close to its roots, relying on decades-old Coordinate Measuring Machines (CMMs) as the go-to technology to get the job done.</p>
<p>Yet increasingly, traditional metrology methods like CMMs do more to slow down the process without adequately delivering accuracy, especially as products sport tighter tolerances, and demand precision manufacturing. CMM&#8217;s use of an articulating robotic arm to direct a touch probe to test individual points along the surface contour of an object doesn&#8217;t support the speed at which companies need to conduct business given time-to-market pressures and the quest for a competitive advantage. In addition, CMMs&#8217; output&#8211;typically a table of coordinate numbers—often results in miscommunication of geometry details with studies showing the report details being misinterpreted as much as 20 percent of the time.</p>
<p>Level 3 Inspection (L3I), with a history seeped in reverse engineering and production in the aerospace industry, recognized early on that there was an opportunity to vastly improve the traditional CMM inspection process. During its work reverse engineering turbine engine parts, L3I found it wasn&#8217;t collecting nearly enough information from its use of CMMs on such complex parts as blades and vanes. As a result, it began the hunt for technology to simplify this engineering task and ultimately bring better quality inspection and reverse engineering processes to the marketplace.</p>
<p><strong>White Light Scanning + CAI = Process Transformation</strong></p>
<p>The search led L3I to a decade-long practice of evolving the use of white light scanning (WLS) and computer-aided inspection (CAI) technologies to change up the traditional CMM-driven parts inspection process. By applying a set of new technology, the goal was to turn the traditional inspection paradigm on its head, substantially reducing the number of physical prototypes and product iterations while speeding up development cycles, often at reduced costs.</p>
<p>At a base level, core technology differences give WLS/CAI an edge. Because a CMM probe is physically moved from point to point to capture surface data, the process is slow and it requires a highly-trained specialist to manually place the calipers and interpret the readings, opening the door to human error when gathering results. Moreover, CMM analysis is limited by its ability to capture a clear and coherent image of the surface geometry. While WLS can yield watertight scans comprising hundreds of millions of points, a complex CMM program, in comparison, might yield a few hundred or at best, a few thousand touch-data points depending on the part size, its complexity, and the requirements. Finally, studies have shown that the digitized surface of the point cloud data, which is the output of WLS, can be accurate up to +/- 0.00004 inches (~1 micron), providing a much more accurate and vastly more comprehensive picture of the entire geometry.</p>
<p>Beyond the physical data capture efficiencies, the WLS/CAI combination also has advantages for data analysis and visualization, the more time-consuming part of the inspection process. Traditional CMMs output tables of numbers are difficult to interpret, even for highly-trained experts, and they do not provide any visibility into the actual geometry of a part. Not so with CAI-driven parts inspection, which generates color-coded plots that can be overlaid with a CAD model for comparison, allowing inspection engineers to easily identify non-conforming part features in a small fraction of the time.</p>
<p>With a technology duo deemed superior to traditional metrology methods, L3I embarked on the journey of transforming the parts inspection workflow. Typically, with a CMM-driven workflow, a prototype or sample part is produced and then compared to specified set of dimensions and geometric dimensioning &amp; tolerance callouts from the inspection blueprint.</p>
<p>In comparison, L3I began to leverage WLS/CAI to study the part&#8217;s geometry first, focusing on the resolution of geometric conformance and deviation, as well as anomalies first, evaluating the form first. The result yielded a number of positive outcomes. For one thing, geometric anomalies that might have gone unnoticed with the traditional workflow are detected earlier, reducing the risk of launching a non-conforming product into the marketplace. In addition, the comprehensiveness of the inspection provides greater insights into the manufacturing process with accelerated optimization and the streamlined workflow, cutting iterations and scrap to cut time to market costs.</p>
<p><img class="aligncenter size-full wp-image-889" src="http://www.knovel.com/contentapp/pdf/5960/5960_files/fig_3.jpg" alt="" /></p>
<p style="text-align: center;">The Smart Inspection Station combines a 3D scanner and Geomagic&#8217;s Qualify inspection software, automating the process of scanning and analyzing parts against CAD models and blueprints.</p>
<p>Consider the new inspection process applied to the development of a shoulder dome implant. The original CMM inspection process, which gathered data from 200 CMM points, indicated that the part was dimensionally acceptable. That same process turned over to the WLS/CAI technology revealed a completely different story. A scan of that same part, comprising 200,000 data points (1,000-times more data), was analyzed, revealing that the part was out of tolerance. While the CMM points overlaid on the 3D structured light scan correlated perfectly to 5 or 6 decimal places, the CMM completely missed a ring-shaped anomaly in the part, detected by the scanner because of the expansiveness of its data collection. In another example, L3I was able to help a jet engine foundry client transform a two-week inspection process that consumed the time of two highly-paid engineers by 95%, whittling it down to a half-day process and saving thousands of dollars per part number.</p>
<p><img class="aligncenter size-full wp-image-889" src="http://www.knovel.com/contentapp/pdf/5960/5960_files/fig_2.jpg" alt="" /></p>
<p style="text-align: center;">This is a cross section of jet engine air foil showing the difference between the CAD design and the actual part. The CAI approach makes it readily visible to see where the part conforms, depicted in green, where it is too small, shown in blue, and where it is too big, displayed in orange and yellow. SOURCE: Level 3 Inspection</p>
<p>Based on those successes, L3I has pushed the promise of WLS and CAI a step further, creating a turnkey, integrated system that automates the complete inspection process. The Smart Inspection Station, which combines a 3D scanner and Geomagic&#8217;s Qualify inspection software, automatically makes precise 3D scans of parts, analyzes the parts against CAD models and blueprints, determines the part disposition, and creates comprehensive inspection reports, all with a non-technical operator in just a few minutes, on the shop floor. Vastly superior production inspection results in very short time.</p>
<p><img class="aligncenter size-full wp-image-889" src="http://www.knovel.com/contentapp/pdf/5960/5960_files/fig_1.jpg" alt="" /></p>
<p style="text-align: center;">Visualization capabilities allow engineers and workers to focus on the areas that need attention, as opposed to wading through tables of numbers for areas that are well within conformance. SOURCE: Level 3 Inspection</p>
<p><strong>The FUD Factor</strong></p>
<p>While the benefits of WLS and CAI seem clear and the technology is fairly mature, it remains a challenge to get manufacturers on board with production parts inspection processes.</p>
<p>Inertia and resistance to change are perhaps the biggest barriers to adoption, keeping the CAI industry focused on early-adopters and professional services despite its 13-year application history. Many companies are so entrenched in their CMM heritage, they think what they have is good enough and that newer WLS/CAI technology is risky, and still perceived as &#8220;too new&#8221;. There are also plenty of long-time CMM specialists who are leery of new inspection technology because of their fears it could have negative career ramifications. Fear of change is still alive and well.</p>
<p>Clearing these hurdles requires a dogged commitment to on-going education and repeated exercises proving out the value of the new 21<sup>st</sup> century inspection processes. Companies also need to understand that CAI is a process, not just an exercise in buying scanner equipment and analysis software. Only by thinking process optimization and by having a clear financial understanding of the time it takes to get a product to market will companies open themselves up to transforming parts inspection and in the process, make better precision products much faster, at lower costs, and with far greater confidence.</p>
