    Wicked Lasers doesn’t just have a fun name. The Hong Kong-based company also likes to have a little fun with its products. In this week’s print column, we wrote about how Wicked Lasers teamed up with marine biologist and TV host Luke Tipple to achieve a dream of “Austin Powers” supervillain Dr. Evil: “sharks with frickin’ lasers beams attached to their heads.” But it seems that being integrated with sharks isn’t the only way for lasers to get some attention.

    The University of California, San Diego, has a great new video on eye protection. It was produced by the chemistry department’s Haim Weizman, who was also the man behind A day in the lab, To be (safe) or not to be, Flash chromatography 101, and a trio of videos on working with pyrophoric reagents and reactive metals. Overall, I think the “splash zone” video is a terrific illustration of why it’s important to always wear eye protection in labs, even when you’re not the one handling the chemicals. That said, the safety glasses featured in the video are really…

    14 May 2012 | 6:57 am
    The other day I was working in my lab with a new student, and we ended up with a lot of image data to transfer from his laptop to mine.  Because I personally date back to the days when computer data was transferred by means of a stack of paper IBM-type punch cards, my first thought whenever I want to move or store lots of data is to resort to some physical medium:  a hard drive or flash (USB) drive, typically.  But my student proposed using a service called Dropbox.  To use it once it was installed, all he had to do was to put the data in a file on his computer.  The…

    7 May 2012 | 6:37 am
    In a talk I gave in Doha, Qatar last fall at an engineering ethics conference, I listed some cultural characteristics that seemed to be necessary for engineering to flourish.  One of the characteristics I listed was “freedom for organizations” to pursue projects in the marketplace of ideas and goods.  Of course, most engineering is done by commercial organizations called corporations, which are legally treated as persons in many ways.  In the U. S., this way of treating corporations goes back at least to the 19th century, and farther if you look into English common…

  • Ethanol in Gasoline: Unintended Consequences

    23 Apr 2012 | 6:03 am
    Since 2007, virtually all gasoline sold in the U. S. has contained 10% ethanol, which is about as much as you can put in most cars without having to do a major redesign of the fuel system.  The reason is a federal law called the Energy Independence and Security Act (ERISA), which until last year also subsidized ethanol production to the tune of 45 cents a gallon and imposed a steep tariff on imported ethanol.  Why was this done?  As is often the case with politically-influenced actions, there were advertised reasons and not-so-advertised reasons.  And now that five years…

    Tornadoes have been in the news a lot lately, both because this season has produced a good many of them, and because the National Weather Service is trying out a new type of tornado warning to people who are in immediate danger.When a tornado’s radar signature is detected, people in Kansas and Missouri will now read and hear warnings that include phrases like “catastrophic,” “extremely dangerous,” “mass devastation,” and “high-end, life-threatening event.”These warnings may have played a role in the fact that while a storm system spawned about 100 tornadoes in Kansas alone…

    What is Oil Refinery and Edible Oil Refinery?When talking about refinery, we need to be able to differentiate and identify an oil refinery from the edible oil refinery. Basically, the oil refinery (or petroleum refinery) is an industrial process plant where crude oil (from crude petroleum) is processed and refined into more useful petroleum products, such as gasoline, diesel fuel, asphalt base, heating oil, kerosene, and liquefied petroleum gas. This is the type of refinery mentioned in the 13 Days: Pythagoras Conspiracy Novel. An edible oil plant in the other hand, is almost similar to the…

    15 May 2012 | 6:26 pm
    The Oregon DOT stopped work on a 10-mile stretch of Highway 20 back in 2010 after several landslides were discovered during construction. Four bridges that were constructed by Yaquina River Constructors, a subsidiary of Granite Construction, were displaced by the landslides. The contractor was paid a total of $173 million for the project, and under the terms of the settlement, $15 million was returned to the State. According to an ODOT spokesman, they are looking to rebid the project this year with a projected completion date of 2015, 6 years behind the original schedule. The winning bid for…

  • Old Maps and Dead Clams Help Solve Coastal Boulder Mystery

    14 May 2012 | 3:00 pm
    This is an interesting geology mystery that they may be getting closer to solving. On top of a 36 foot high vertical cliff on the coast of Ireland is a tabular bedrock formation. Giant boulders of this material have been pushed inland at a rate as high as 1 foot per year and initial research indicated it would have to be a Tsunami to move them. But Ireland hasn't had a Tsunami since 1755. Evaluation of historic maps prepared by surveyors and carbon dating of tiny clams in the crevices of the rock indicate that the movement has indeed been happening in the past 60 years, indicating that storm…

    The largest comprehensive analysis of ClinicalTrials.gov finds that clinical trials are falling short of producing high-quality evidence needed to guide medical decision-making. The analysis, published today in the Journal of the American Medical Association, found the majority of clinical trials is small, and there are significant differences among methodical approaches, including randomizing, blinding and the use of data monitoring committees. This is a critical issue as medical studies continue to leave quite a bit to be desired. Even more importantly the failure to systemically study and…

As simple as the example is, I really did learn a…

    14 Feb 2012 | 8:24 am
    It is one of my dream to write a chemical engineering related fiction novel. My wife knows that fact. It will be cool to integrate the experience which I had in the industry and my chemical engineering knowledge in a book which can be read by everybody (but special for chemical engineers and those who are in related industry). What if the novel is adopted to become one of those Hollywood movies. Would that be great? However, I don't think I can make it in the near future. It's quite tough especially with my hectic schedule and my main target to complete my Ph.D. Well, enough about…

  • 1st Scientific Research Publishing Workshop in Shanghai, China

    Last December, my wife participated in a Scientific Publishing Research Workshop in Shanghai China from 20-22 December 2011 to present her technical paper about Progressive Freeze Concentration (PFC). The research is directly related to her own Ph.D and her present core research. I accompanied her to Shanghai and at the conference I joined as a participant.The workshop is not specifically tailored to chemical engineering only. It combines chemistry, biochemistry, maths and several other disciplines. I can say it is a highly multi-disciplinary workshop. The participants came from all over the…

  • Importance of Boiler Chemicals Water Treatment

    24 Jan 2012 | 5:07 am
    Since I have written my experience visiting a boiler manufacturing company recently, I think it is good if I follow up with another article related to boiler. This time, it is about the importance of boiler water treatment chemicals. I remembered monitoring the boiler man blended and poured some chemicals (from Nalco) to be injected into the boilers.[Flash back: Some of my boiler experience story (explosion) for you to read. Boiler Explosion Part 1 & Boiler Explosion Part 2.]Do you know that like cooling tower, a boiler also requires chemical treatment for various reasons. When I was a…

  • Cloud Virtualization. Cloud Standardization is unavoidable

    igormoochnick
    22 Apr 2012 | 6:24 pm
    [This is a repost from my post on BlueMetal Consulting company blog] I think it’s time to start talking about Cloud Virtualization. Today cloud diversity is driving customers out of the clouds instead of embracing them. Multiple cloud providers are trying to lure customers in by developing feature specialization and this may well serve to fracture the markets and the community even more. Specialized clouds have a good reason for existence, but an explosion of many different ‘flavors’ of clouds are creating a similar problem to choosing an insurance policy – there are thousands…

  • Controlling TopShelf via REST interface + Dashboard

    My recent update for the TopShelf enables the new Nancy-based REST interface and provides improvements to the current dashboard. The new REST interface allows you to see what are the currently running services by sending a GET request to the dashboard URL (i.e. http://dasboard_url/services). As a reply, you’re going to get a JSON block that contains small snippets of information about each seevice and shelf that is running inside the TopShelf process.

  • Adding Nancy to the existing ASP.NET MVC site

    There is an issue adding Nancy to the ASP.Net MVC site due to a simple fact that MVC controls the routes not through the web.config but through the routing table. If you adding Nancy to the existing MVC site – make sure to remove the sub-route that controlled by Nancy from the routing table. Here how it works: 1. Follow all the steps from the Nancy Documentation Wiki 2. Add your module and make sure that it has an “offset” path (via inheritance) public Module() : base("/nancy") { ... } 3. Remove the “nancy” route from the Routing table in the Global.asax.cs…

I’ve had a chance to build the realistic distributed application live-coding from scratch. The application consisted from 2 roles – web role and a worker role. During the demo I’ve used the Amazon AWS cloud, but the similar technique can be applied to Azure deployments.

    Foreclosure is seen as a last resort for many, perhaps a reminder of mistakes made in investing or how the bank that you’ve given countless fees to over the years, let you down, lending you money for a home they should have known was risky. The infographic below tries to cut through the emotions and gives some hard stats on what options are out there and what impact your choices might have on your future wealth and credit score. While we are continuously reminded that “things are different up here in Canada”, its a reminder that most people going through foreclosure NEVER…

  • Writing by Hand

    Sometimes you just need to take out your favourite pen and write. This is how I felt at lunchtime today, so I walked to Starbucks, remembering my pens, iPhone and e-reader, but upon sitting down, I realized that I had forgotten an essential piece of technology, my journal. So, taking a deep breath and a sip of Americano, I read. Not the outcome I was looking for, but satisfying in it’s own right. In this information-soaked age, it is almost impossible to be more than a couple of steps away from something that can rapidly deliver information and/or entertainment. And, perhaps as a…

  • Tall Timber Buildings

    Mike Thomas
    26 Mar 2012 | 11:00 am
    With the failure of the suburban experiment, rising house prices and a greater desire to be in the downtown, designers are looking to stretch the limits of materials, to satisfy changing needs. Added to this, Canadian designers are looking to find ways to use pine beetle infested timber from our forests. But now, designers are daring to imagine buildings of 20 to 30 storeys held up by nothing more than gargantuan plywood beams. Made possible by new advances in wood technology, they will be fire resistant, earthquake proof, cost-competitive and built in a fraction of the time taken to pour a…

    Over Christmas my family and I traveled back to Australia for the first time in five years. There had been several reasons for our not returning sooner, high on our list was the cost, and a close second was the actual ability to take a month off to make the trip worthwhile. In a new job, with a gracious boss, I was able to take this time off over the holiday season, swapping rainboots for flipflops and skis for a beach towel. Having been heavily involved in the sustainability scene over the past 5 years, I know full well the environmental consequences of our decision to travel, (just…

Well, if you're a reader, go read this article from The Economist (my favorite magazine) before we proceed: http://www.economist.com/node/21554540/ The part about Google, Apple, Samsung and other handset manufacturers needing to quickly trade patents seems to make sense at first, right?

As some you may know, I'm the co-host of an electronics podcast called The Amp Hour. It's a lot of fun and our listeners run the gamut of hobbyists to professionals.

One of his other notable achievements is the Forth Bridge, a revolutionary bridge made from hollow steel tubes to create the cantilever. He made many other notable contributions to civil engineering, including his work as an expert witness at the public inquiry into the Tay Rail Bridge disaster. In 1867 Baker wrote a series of articles, “Long Span Bridges,” discussing the application of cantilevers.

I have a satellite dish antenna fixed on a floating platform that is anchored/moored in a bay area. Although the sea is always very calm with no movements, with the changing currents, the platform turns in various directions gradually and the satellite dish antenna have to be re-oriented every now and then to tune in the signal. Instead of having to use the remote controller to rotate the antenna a few degrees to compensate for the positional change of the platform, I…

We specialize in accurately mapping bodies of water, calculating the water volume, collecting sediment depth samples at critical areas and monitoring the distribution of sediment over time. Common questions from our clients: Where is the highest sedimentation occurring? How much fluffy sediment (in cubic yards) is in each cove? If the lake is drawn down 5 ft, what would the shoreline look like? How much water (gallons and acre-ft) is in the lake? If we make each cove a minimum…

And since then, the Transportation Investments Generating Economic Recovery Discretionary Grant program — better known as TIGER — has funded more than…

  • An Engineer’s Two Favorite Tools

    TweetOne of the coolest things about being an engineer is that we have a wide array of gadgets and tools with which to do our work. Calculators, tablets, software, apps—the possibilities are nearly endless. And believe it or not, we, as engineers, are also collectively possessed of pretty great senses of humor. So, when it comes to an engineer’s must-haves, this simple flow chart boils any problem down to one of two solutions: WD-40 and duct tape. How do you decide which is the best tool for the job? That’s simple—all you have to do is ask a few questions and use the resulting logic…

  • My Raspberry Pi Thinks It's a Mainframe!

    As the Raspberry Pi started to ship the Sinclair ZX Spectrum turned 30 years old, and comparisons were being made between the two and their role in providing access to affordable computer hardware. Given the phenomenal advances in computing since the birth of the ZX Spectrum, I thought it might be fun to compare the Raspberry Pi with a computer that was closer to the state of the art at around that time, and to see if the Raspberry Pi could fill its shoes... Introduced not long after the ZX Spectrum, the IBM 4381 processor was the workhorse of mainframe computer installations that could fill…

We were lucky to get our hands on one of the first few Pi’s and so I’d like to share with you how we got on with it. Setting up the SD card was…

    A few months ago, Southern California Edison installed a new smart meter onto my house.

    Two technological forces have driven human behavioral change since the beginning of the 21st century: digitization (The Media Revolution) and distribution (The Network Revolution). For better or worse, these “revolutions” have become known colloquially as “social media” and “social networks” respectively. Rather than getting into a squabble over the ever-morphing definition of social media and social networks, I want to focus on the technologies responsible for each revolution: mediums (Yes, grammar police, I know) and networks.

    A few months ago, I was asked to participate on a panel for UCLA’s Career Week. I jumped at the opportunity because I’ve found that whenever I speak with college students, I always learn something. This experience was no exception. Last Thursday, I joined a panel with four others to discuss social media. Simple, right? But things got a little odd when the panel was introduced similarly to those who spoke earlier of careers in engineering, government, finance, politics, public security, international business, education, etc…. The problem is that social media is NOT a career. Social…

  • US Crowdfunding: A Step Forward

    Ron
    27 Mar 2012 | 2:38 pm
    Last week, the Senate passed a modified version of H.R. 3606, essentially adding investors protections through increased SEC filing requirements. Today, the House passed the Senate’s version of the Bill by a vote of 380-41, sending it off to President Obama to be signed into law. This soon-to-be law is drawing criticism from both ends of the extreme. Some see it as the ultimate panacea of entrepreneurial opportunity. Others see it as a tool for hucksters and charlatans to separate us from our hard-earned money. I’m willing to bet that the truth lies somewhere in the middle.

    Successful, million-dollar Kickstarter projects such as DoubleFine Adventure and Elevator Dock have proven that there is a demand for crowdfunding. Small businesses are using intermediaries like Kickstarter to help them pre-sell yet-to-be-developed products, and thousands of “backers” are lining up to accept their offers. But what if one of these Kickstarter backers wants more than just a game, a tee-shirt, or an Elevator Dock? What if they want a piece of the company or a piece of the project? Wouldn’t it be possible for someone like Tim Schafer to sell stock in his…
