What if there was a Robot cheering for those fans?
The Hanwha Eagles, a much beleaguered South Korean major league baseball team have introduced Fanbots, jersey-clad robots who lead cheers, display messages (and selfies where the robot would otherwise have a blank screen) sent in from fans at home, and generally stand in for fans who aren't there.

Like Mortal Kombat, but in real life
Imagine if you could toss two trained fighters into a ring, give them whatever weapons they want, and and let them go full-on Spartacus on each other without anyone getting seriously injured. With the death element removed, even the most die-hard pacifists would have to admit that it'd be pretty damn entertaining. With their new carbon fiber damage-measuring armor, that's exactly what Australian startup Unified Weapons Master wants to do.

The Call Is Coming From Inside The Grave
"If the phone rang and you were in another room, you had to come running: in that immediate sense, and in a way that now seems comical, your phone controlled you. And before the '90s, there was no caller ID, an inconvenience which ensured, for that benighted first century-plus of the instrument's analog existence, the first premise of phone horror—that you could never know for certain whose voice, or what sound, would issue from the other end of that raised receiver." - HiLoBrow is in the middle of a series exploring the tropes and history of Phone Horror. Of particular note is the brief historical connection between the telephone and the world of occult crypto-science - The Atlantic explains further.

The Disruption Machine
What the gospel of innovation gets wrong. The championing of "disruption" in modern business is built around some very flaky research that does not bear out its sweeping conconclusions.
The Machine
HP scaling memristor and photonic computing: "the device is essentially remembering 1s or 0s depending on which state it is in, multiplying its storage capacity. HP can build these chips with traditional semiconductor equipment and expects to be able to pack unprecedented amounts of memory—enough to store huge databases of pictures, files, and data—into a computer. In theory, that would remove the need for a conventional slow disk/fast memory system. With the Machine's main chips sitting on motherboards right next to the memristors, they can access any needed information almost instantly..." [more inside]

Lockheed Martin is in a race with SpaceX who recently made a big splash with 3D printed spacecraft parts. Lockheed shows its vision (video) for a next generation 3D printer, capable of printing not just parts but an entire plane as a print-job (c.f. previously war robots). This technology may perhaps combine with a new class of fractal nano supermaterials, which are stronger than steel but nearly as light as air, the promise to create mass produced ultra-light vehicles, aircraft and other things.

"You Crazy Bastards. What Have You Done? Now I Have To Rebuild!"
In 2003, Andy "waxpancake" Baio created Upcoming, "a collaborative event calendar focused on interesting arts and tech events around the world, curated by its community. It surfaced weird and wonderful events that usually fell under the radar of traditional event listings from newspapers and local weeklies." In 2005, it was acquired by Yahoo!, who killed the site last April with little warning, and no way to back up events. Fortunately, the complete site was saved by the Internet Archive. But Upcoming isn't dead yet! Two months ago, Yahoo! offered to sell the domain back to Baio. And now, with a fully-funded kickstarter, he's planning on "rebuilding it for the modern era using tools and platforms that weren't available when it was first designed." Welcome to the brilliant life, stupid death, and improbable return of Upcoming.org. [more inside]

You feel like you're carrying the abuser in your pocket.
Sarah's abuser gained access to every password she had. He monitored her bank accounts and used her phone to track her location and read her conversations. She endured four years of regular physical and emotional trauma enabled by meticulous digital surveillance and the existing support services, from shelters to police, were almost powerless to help her.

Snowden To Address Audience in First Live Q&A, Days After EU Testimony
"The good news is that there are solutions. The weakness of mass surveillance is that it can very easily be made much more expensive through changes in technical standards: pervasive end-to-end encryption can quickly make indiscriminate surveillance impossible on a cost-effective basis. The result is that governments are likely to fall back to traditional, targeted surveillance founded upon an individualized suspicion. Governments cannot risk the discovery of their exploits by simply throwing attacks at every "endpoint," or computer processor on the end of a network connection, in the world. Mass surveillance, passive surveillance, relies upon unencrypted or weakly encrypted communications at the global network level."
Edward Snowden submits written testimony to an EU committee investigating mass surveillance, and answers questions. The testimony takes place 3 days ahead of his highly anticipated SXSW appearance, to take place later today. Snowden is expected to speak about privacy, security, mass surveillance programs, free speech and whistle-blowing in a rare remote video appearance before a live audience.
Kansas Congressman Mike Pompeo finds this "deeply troubling" in a letter he's sent to the organizers of the conference.
Meanwhile, people who wish to #asksnowden questions can use the hashtag on Twitter. The talk is to take place at 12pm PT, today.

It's been a bad week for people's phones
Denmark-based security firm Heimdal detected the malware, called "Mazar," which sends text messages that include an ostensibly harmless multimedia message link to users. Click through, and it downloads Tor to your phone, and then the actual malware, whose source the Tor software hides. (By the way, a little reminder for living in the twenty-first century, friends: Don't click on text message links from random senders.)
Heimdal thinks that over 100,000 phones have received the Mazar text in Denmark, the BBC reports, and the firm isn't yet sure if it's spread to other countries.
We've heard of such one-text menaces
Weirdly, the new malware can't infiltrate devices using Russian as their default language. Setting your phone to a foreign language seems like an extreme measure when common sense should keep you safe.

Will two different sized breast implants set at different rates?
I'm 7 days post op. I was horribly uneven pre-op, and I still feel the same amount uneven even though there was a 100cc difference in the implant size between the breasts (600 on left, 700 on right) my left looks great, but my right still looks significantly smaller, and less round than the left. Could the implants be setting in at different rates based on the size difference?
Doctor Answers 2
What to do with early asymmetry
An uneven appearance this soon after surgery is expected if you started with a fair amount of asymmetry. However, without an exam and without photos, it would be wrong of me to suggest that your course is normal. Give your surgeon a call and get in to see him/her as soon as possible for an exam and to help you understand your course.

Will two different sized breast implants set at different rates?
Schedule an appointment with your Plastic Surgeon to discuss your breast. One breast could be more swollen than the other, but I would also ask to see a copy of the operative report to confirm the breast implant sizes used.

Pros: Gigabit Ethernet, Easy installation, IPV6. Has a lot of management options.
Cons: The interface for me is confusing, ugly, and difficult to navigate. I find everything (at least what I needed), but I have to look for what I want.
Other Thoughts: As I said, the interface is not so great, the functionality however, is great. I bought it because wanted to play around IPv6. It supports IPv6, but not tunneling. I had to enable telnet on it and configure manually for the tunnel but works. I like how you can set the wireless. Isolated connections, different password for 2.4, 5GHz, and you can make Guest networks too. I've never tested speeds, though. I have a desktop and a NAS wired to it, and using wireless devices.

For production process control of complex components, Computed Tomography (CT) has become the technology of choice for many inspection and metrology tasks, e.g. for automotive castings, aerospace turbine blades and 3D printed parts which by nature have hidden features. A major challenge is the increased cycle time requirements combined with high inspection depth which requires improved methods to deal with imaging artifacts. X-ray scatter is the main limiting factor for such artifacts in CT. While state of the art scatter reduction simulates scatter based on CAD data or sample material properties, the new method measures the scatter portion of that specific sample in the CT scanner and minimizes it from the CT result for every individual voxel. This new method drives inspection throughput and precision of high energy CT applications to scan difficult to penetrate samples with a relatively high atomic number such as metals, which are actually performed with highly collimated classical 2D fan beam CT. In our presentation we will show comparison study results between up to 100 times slower fan beam CT as well as conventional, scatter radiation impacted cone beam CT, and advanced scatter reduced cone beam CT. The new method will not only substitute slower fan beam minifocus CT in many application cases: we will show other case studies where 300 kV microCT scans can now be applied for inspection tasks were normally the investment in more expensive 450 kV high energy CT equipment would be required. We will also show the influence of advanced scatter correction technology on 3D measurements. Considering the fact that 3D metrology with CT always uses automatic surface detection algorithms to determine the surface of the 3D volume to measure, compared to conventional cone beam CT the new method allows more material penetration (up to 30%) at the same scan parameters to still determine the exact surface. At same material penetration length, the new scatter correction method allows a more precise surface detection due to less artifacts negatively affecting the metrology results.

The motion of a projectile inside a gun barrel results in the unwanted heating and wear of the interior rifling of the barrel, which necessitates squad machine-gunners carrying multiple spare barrels. Therefore, the ability to do in-barrel characterization (interior ballistics) to image kinetics of the moving projectile before it exits the barrel is critically important for gun barrel design. Here we report on the development of a high-speed X-ray imaging system capable of imaging a projectile as it travels at high speed inside the barrel of a gun. A key component of the system is a specially designed scintillator that serves as the X-ray-to-light converter. This custom-developed scintillator has an extremely fast decay time, high X-ray absorption efficiency, and very bright emission. The optical image generated by X-ray conversion within the scintillator is captured using a custom intensified CMOS camera that allows mega-pixel resolution and up to 500,000 frames per second data rates. The X-ray source is a series of four pulsed X-ray units, each of which produces a single 20 ns burst of high intensity X-rays. Triggering electronics were developed to fire the X-ray sources sequentially such that the detector integration window and the pulse duty cycle are synchronized. Here we will discuss our results imaging .30 caliber bullets traveling at ~1,000 m/s while still in the barrel. Information on bullet deformation, pitch, yaw and integrity are the main goals of this experimentation. Planned future upgrades for imaging large caliber projectiles will also be discussed.

As deterioration progresses, concrete structures such as bridges, tunnels, and dams develop deformations like cracks or delamination. Measuring these deformations accurately and providing proper countermeasures for managing rehabilitation of public infrastructure is of growing importance. Traditionally, concrete deformations appearing in concrete surfaces were inspected by technically-trained inspectors using visual observation or a hammering test. These methods may produce differing inspection results due to external factors such as individual variability of visual or auditory senses or field conditions such as light level, traffic noise, echo, etc. However, measuring these condition changes are a large factor in judging the progress of deformation. Cracks are one of the major deformations in concrete structures. In detecting crack deformations in concrete surfaces, we used a method that takes a high resolution concrete surface image with a 20MP general digital camera and can detect crack widths of more than 0.2mm automatically by using image analysis. This auto crack tracking image analysis method can extract cracks of one-fifth of the width of 1 pixel (mm/pixel) automatically by analyzing gray shade difference in each pixel. In this report, we introduce a case study of a gravity dam inspection. Purposed for flood control, the dam structure has a height of 75m, length of 285m, and total surface area of 20,000 sqm. We photographed the dam from a distance of 200m using a digital camera and detected cracks with widths up to 0.2mm. Finally, we created a flattened, curve distortion-corrected deficiency map of crack widths more than 0.2mm. In addition, we also introduce another case study on a rail tunnel inspection. This inspection photographed the rail tunnel by using seven cameras mounted on one rail trolley; the inspection method automatically stitched tunnel wall images and detected tunnel cracks. We inspected the tunnel periodically because there was ongoing construction of new structures adjacent to the tunnel. Inspecting on a periodic basis, we compared accumulated crack length and width from each result. As a result, we were able to evaluate if there was any crack progression over time. We found that in spite of nearby construction, crack progression was minimal and did not require rehabilitation. These results validated the feasibility of comparing annual progression of cracks in the concrete. These case studies suggest that for large structures, which have large inspection areas or long inspection spans, automatic crack detection using images from a distance without approaching the surface is effective to ensure safe and quick fieldwork with fewer inspectors. Using auto crack tracking image analysis, this method can detect hairline cracks of more than 0.2mm width at the same level of accuracy as visual inspection. Using this method, we can analyze and show quantitative crack width progression over time.

X-ray Assisted Defect Recognition (ADR) Project Summary for MIM parts
Presenting author(s): Mr Francisco J Miranda
Room: Celebrity A | 11:30 AM Monday, July 25, 2016
In collaboration with a digital radiography system developer, GE Sensing & Inspection Technologies, develop Assisted Defect Recognition (ADR) algorithms to be applied to the digital x-ray image of medium complexity geometry parts produced from powder metallurgy. Phase 1 of the project is to complete a feasibility study with the industry partner to develop applicable recognition algorithms. Future phases of the ADR project will involve the development of fully Automated Defect Recognition algorithms and system design. Benefits of implementing ADR include obtaining objective inspection results, increased reliability, reproducible decisions, high throughput, and reduced impact from human factors. Initial phase of the project is to define ADR algorithms that will check for the presence/absence of indications with the inspector making the final accept/reject decision. Classifying the defects by size or location with ADR is not required. Sample parts were collected containing various types of indications, porosity, inclusions and cracks. The indications are expected to have different gray values than the surrounding areas, but may not be in a consistent pattern and may occur in areas where the gray scale changes are due to part geometry. Preliminary digital imaging of the test parts was performed to determine the magnification and resolution required for ADR. The test parts were imaged using GEIT's Micromex HD system with 180kV microfocus source and DXR250RT 200 micron detector. It was established that all the known indications in the test parts were capable of being radiographically detected/imaged. Understanding the threshold of defect detectability is required. Factors affecting detectability include: - Indication size (width x length). - Indication type (linear vs. volumetric). - Contrast (depth) of the indication, generally 2% loss of material. - Location of the indication on the part. - Part geometry. Four (4) ADR algorithms were developed and combined to evaluate the test parts. Parameters such as defining the maximum allowable percentage of all voids relative to the calculated part area, establishing the minimum size of voids to be detected, and the contrast between gray level values for voids compared to the surrounding area were set. The integrated ADR software was only able to detect a portion of the voids in the test parts. Good correlation was achieved between the digital image detections to the ADR detections only for certain sized voids in specific part locations. It is considered that for these part types and inspection application, refining the algorithms will result in ADR detecting indication sizes down to 0.008 x 0.02 inch (0.2 x 0.5 mm) with a minimal depth of approximately 3% of the material thickness at an average of 2 - 5% false reject rate. The detectable flaw size is dependent on the focal spot size, detector resolution and magnification—not the software. The results (false reject rates) depend on part material and geometry.

To maintain and ensure safe railroad operations new technologies must be developed for wood crosstie inspection before and after installation. Installed crossties are inspected at 25mph using a 2D fan beam backscatter radiography method. The Railway Tie Association forecasts 23,700,000 new crossties will be purchased in 2017. Currently newly fabricated wood crossties are not radiographically inspected for internal flaws and adequate penetration of degradation prevention treatments. There is a market need for a 3D radiographic inspection of newly fabricated railroad crossties. Building on 2D fan beam backscatter technology, information about how radiation scatters within an object is valuable for 3D computed tomography. Transmission radiography methods are based on only the line attenuation between two points. Scatter radiography methods are the product of illumination beam attenuation, total scatter signal from the intersection of the illumination beam and detector field of view, and the attenuation of scattered radiation. Unique transmission, forward scatter, side scatter, and backscatter radiography perspectives of a translating object will collected from each stationary X-ray and/or gamma ray fan beam illumination source. The reconstruction method iteratively converges the density, not the attenuation coefficient(s), of each voxel in the object region by comparing the predicted and measured transmission and scatter signals. Ranges of densities are correlated with the absorption and scatter cross sections of known materials such as air, wood, water, ballast/rock, Aluminum, Iron, and Lead. Signal differences of the transmission and scatter perspectives are combined to successively estimate voxel composition and density to minimize signal differences.

As radiographic technology continues to evolve, we have seen X-Ray Systems get more compact, and easier to use. With advancements in Digital Imaging and the rapid conversion from analog film imaging, the next logical development is improving the actual X-Ray generators to better satisfy the requirements of the use of Digital detectors. This paper encompasses the most recent developments of compact, high power, ease of transport and service X-Ray sets with energies up to 200 kiloVolts. As Digital detectors can produce images in many cases equal to or superior to analog film technologies, consideration with regards to X-Ray systems is given to actual "R" output, focal spot size, portability, wireless operation, battery power, and computer compatibility. New Generation X-Ray systems are easily transportable, lightweight, and are advantageous in many inspection activities, especially in field and flight line operations. The typical High Voltage and sophisticated control cables are noticeably absent eliminating the need for festooning and cable ways. "R" output is High Frequency, focal spots are fractional, and controls can be installed on a computer, in some cases compatible with Imaging control modules. This paper will address the evolution of the "X-Ray Set" from large stationary line voltage technology to present day high output compact systems, easily transportable, and compatible with both analog and digital imaging technology.

Los Alamos National Laboratory has recently completed the qualification of a computed tomography process for the evaluation of small parts. The system is based on cone beam and digital detector array technology. ASTM International Digital Detector Array (DDA) and Computed Tomography (CT) standards were used to develop a process control program. ASTM E2737 and E2698 were used to create a series of baseline tests for the individual DDA images that make up the CT data set. Spatial resolution, contrast sensitivity, efficiency, detector offset, and lag are performed initially and then repeated on a periodic basis to ensure the digital detector array is operating within tolerance. ASTM E1695 spatial resolution and contrast sensitivity tests are used to assess CT baseline and stability. The complexity of these tests, in addition to the frequency at which they are to be executed, necessitated the development of software to automatically analyze the process control data. To this end, Graphical User Interfaces (GUIs) were written using the scripting language, Python. Data gathered since initial qualification is presented.

Recent developments in Digital Radiography (DR) and Computed Tomography (CT) have provided means of producing images with higher spatial resolution while using mini and conventional focal spot tubes in conjunction with standard pixel pitch detectors. These developments involve innovative approaches in improving spatial resolution with geometric magnification as well as further increasing the spatial resolution of the detector beyond the normal SRb. These developments have also led to a method of reducing CT ring artifacts and the need for long acquisition of gain corrections. These breakthroughs provide opportunities for higher flux output x-ray equipment to be used in meeting the more stringent industry specification requirements. With these advancements, we can expect DR and CT to continue to improve in image quality and further expand into applications never before considered.

X-ray Computed Tomography (CT) has made significant progress and growth over the past years, enabling the internal details of complex parts to be inspected, visualized and even measured using highly advanced hardware and software tools. However, the ever-growing number of applications and the rising demand for Automation increases the complexity of how to quantify overall CT quality. In this presentation, the authors will summarize the most common industrial CT techniques and more importantly, how these techniques are applied to a variety of new applications. Once these applications have been described, the effects of Automation and growing requirements for "Big Data" are outlined in order to determine and evaluate the required quality of these various scans. A variety of current IQI devices and proposals will also be summarized along with guidance for determining the best ways for typical users with different priorities to specify and prove out the required quality of their CT scans. The quality of the scans must fit the application, and the automation of acquiring this data is proving to have an impact on this evaluation.

Coordinate measurement machines (CMMs) have been a long trusted source for accurate measurement in the field of dimensional metrology. However, the changing manufacturing environment is continually challenging use of CMMs as a tool for reliable measurements. Advances in materials and processes, have made new designs possible with greater flexibility, complexity and internal features. Computed tomography (CT) promises solutions for many of these applications where CMMs cannot. Unfortunately, it has been difficult to verify the accuracy of CT measurements due to generalized surface extraction techniques employed by various software packages. Such generalized techniques result in loss of accuracy and prevent direct correlation with CMMs because of the inability to match precise target points on geometric features. This presentation investigates one of the key causes of the dimensional measurement uncertainty of CT data – the method of locating the surface. Generalized surface extraction techniques are compared with targeted surface point extraction using adaptive threshold techniques for the measurement of various geometric features. Both methods are then benchmarked against CMM measurements of the same geometric features with the same target points to demonstrate the impact of these different methods on measurement uncertainty.

Over recent years, large strides have been taken toward a broader industry acceptance of digital imaging (CR and DR) technology. This includes the creation of ASTM/MAI industry standards to provide guidance through the selection and installation stage as well as the development of advanced methods for data retention and management, which are regulated through the DICONDE imaging communication protocols. Before any of this can occur, one must be able to understand the many benefits of a film to digital conversion, including the financial and work process improvements. Calculating and communicating these benefits and ROI to senior management and the Finance team is often as challenging as the transition to new technology and techniques itself. It is also vital to gain widespread acceptance of the changes in order for the benefits to be fully realized. This discussion will focus on developing the financial ROI and shop floor education packages for digital conversion that facility and technical users alike can utilize to support the film to digital conversion transition in your business.

The oil and gas industry has utilized film radiography for the evaluation of pipeline welds for many years. The world has evolved, and today people are easily sharing digital images as part of the information revolution. Computed radiography (CR) is ready to replace film radiography for portable outdoor use applications. CR technology adoption has been contingent upon achieving acceptable image quality and getting enough imaging plate use cycles to be profitable. Image quality is dependent upon shot conditions, imaging plate type, reader settings, and scatter control. Likewise, the number of achievable use cycles is dependent upon the imaging plate design for durability and the user's operating environment. This presentation reviews the basic principles of storage phosphor imaging plates. Usage criteria and guidelines for optimum image quality and maximized overall use cycles will be discussed for various imaging plate types. A comparison of film and computed radiography imaging plate technology will be presented.

Varian is developing a strip detector based on its amorphous silicon (a-Si) technology that will be modular and highly configurable such that it can be used in a wide range of industrial and security imaging applications of various energies and dose levels. The imager will accept both 1D and 2D scintillating arrays and well as standard scintillators. Currently, we are testing a variety of scintillators for comparison that include DRZ+, CsI, and CdWO4 arrays. Two CdWO4 arrays were tested, 1.6 mm pitch, 3 mm deep, polished with a 26.5 μm septa and 0.784 mm pitch, 4 mm deep unpolished with a 26.5 μm septa. The a-Si is a modified 1515DXT-I imager, with standard 127 μm pitch, but will be able to run in excess of 200 frames per second (fps) and in 2x2 binning at over 600 fps that allows for imaging on a pulse to pulse basis for an accelerator. The module will be designed to be tiled for scaling to large field of view applications. The x-ray source is a HPX 450-11 tube for the kV measurements and an M1 Linatron for the 1 MV measurements. Measurements for CNR and resolution will be performed per the ASTM E2737 for the different scintillators at 320 kV, 450 kV and ~ 1MV. Additionally contrast improvement will be demonstrated for real-time motion radiography using a shift and stitch time integration technique. Preliminary results at 450 kV with the 1mm focal spot, the 1.6 mm pitch CdWO4 array was able achieve 1-4T sensitivity through 4 inches of steel with a CNR of 5.23, and 1-1T is visible with a CNR of 3.09 with a 180 second exposure. For comparison, 1-4T hole was only barely indicated with 0.91 CNR for a 180 second exposure at the same dose rate for DRZ+. Additional results will be presented and discussed in detail for the other scintillators and energies.

NDT with RT method has its major application in pipe inspection. However, pipe varies greatly in size and wall thickness. This has resulted in many choices and configurations in pipe NDT. In general, single wall RT would generate much better image quality than that of double wall. Most users would keep single wall configuration as much as practical. However, when pipe diameter goes smaller, there would be less choice because many standard devices, like flat panel, crawler etc, will not fit into inner pipe. Although film and CR phosphor screen are still an option, a slim long version LDA-like DR device would become necessary to increase NDT productivity. This DR device is now available in market. With 50um / 100um / 200um pixel size, off-axis low noise design and 320kV or more X-ray rating and its more than 200 ft long GigE data cable, it can easily go through a pipe with 3 inch inner diameter. This kind of pipe-specific LDA would also give user more choices and greater flexibility for X-ray generators. Scan images are presented and results are discussed.

As the migration of digital imaging continues to expand from the primes down the chain of manufacture, the opportunity to integrate QA chain improvements along the entire process is approaching. Given that NDT managers and QA staff have an already demanding job profile, documentation and verification software "apps" have the ability to make their jobs easier and decrease error. As these apps grow, it is just as important to have interoperability between platforms. From mobile devices that we all carry with us daily to the reporting tools integrated into inspection software, making use of this data is of key importance and interoperability standards are the path. This presentation will discuss use cases of apps, their role in the supply chain, and present the reasons interoperability is critical.

X-ray computed tomography (CT) is a three-dimensional measurement technique with many advantages for industrial inspection and quality control. It enables us to see parts' external surfaces and extract parts' internal features in a nondestructive fashion. CT is widely used as a technique for quality control, but it is not as well known for its capacity to evaluate dimensional information. This paper presents a comprehensive review of the use of CT for dimensional metrology with an update on the international efforts to create standards for metrological testing and uncertainty assessment. Figure 1 illustrates the workflow chart for the full CT process that includes evaluation of dimensional measurements. In the field of dimensional metrology, CT can obtain dimensions of internal features normally inaccessible with CMMs, and thus parts can be inspected not only for go/no-go, but also for traceability with quantifiable measurements. In particular, tolerances can be contrasted with different processes using nondestructive measurement of the manufactured product. There is considerable benefit in measuring the products in the assembled state, not only for comparison of results but also for tracking dimensional changes after assembly or when modifications are deliberately applied to a single process or to a particular component. With accuracies comparable to or (in some circumstances) better than coordinate measurement machine (CMM) data, industrial X-ray CT machines can acquire a specimen's dimensions and contribute to the area of metrology and geometric tolerance control, which is very important in the assesment of a part's functional features. This permits for the detection of dimensional deviations and identification of differences or accuracy issues. This is particularly relevant for parts built with a variety of manufacturing processes including additive manufacturing. In addition, X-ray CT can be used as a quality control tool from optimization to production or to identify or prevent failures quickly, which saves both money and time.

It's been a bumpy market since late February. 125 on the SPY is looking mighty close, and my best guess is we will see 120 before the next big leg up. A quick look at the sector funds over the past three months will tell you that money is shifting to the more defensive areas of healthcare (NYSEARCA:XLV), utilities (NYSEARCA:XLU), and Consumer Staples (NYSEARCA:XLP).
If you are one of those people thinking of selling off a couple of those higher-risk speculative stocks but still want to stay invested, here are a couple worth looking at.
Creating the Defensive Scan
To begin, we start with stocks in the small- to mid-cap range between one and three billion. We select from three of the defensive sectors, then create filters that call for a reasonable trailing PE, lower forward PE using next year's estimate, and an even lower forward PE using the EPS estimate in two years from now.
I back-tested this over the past two years using Zack'sResearchWizard. I also added in the robust test where it staggers your buying over 12 different starting weeks to make sure you didn't accidentally pick the right week to begin your test with. As you can see with the chart below, it's been quite a strong performer over the past two years with a very tight grouping. The bottom line is the two-year performance of the S&P 500 index.
Below are some of the stats on this back-test for you number junkies. The highlights include a win ratio 10% better than the market with twice the average annual compounded return and a smaller average losing period than the market with a relatively small max drawdown. The holding period is three months or 12 weeks.
Defensive Stocks Making the Cut
Fresh Del Monte Produce, Inc. (NYSE:FDP) – Some fairly big earnings growth expectations lie with this food producer. This year it expects to see a 48% increase and next year a 63% earnings pop. The recent quarter had a nice 26.30% positive surprise and all earnings estimates were raised across the board over the past month. A nice stable price makes this a timely defensive buy right now.
Health Net Inc. (NYSE:HNT) -- Sales growth looks to turn negative while earnings are expected to grow 15% this year and 13.5% next. Again, some nice positive earnings revisions right across the board over the last 30 days. While prices have pulled back 10% over the past month, the support of $31, and $29 below that, could give a nice entry.
Brookfield Infrastructure Partners L.P. (NYSE:BIP) – This utility company has a healthy 5.1% forward annual dividend yield. This stock has been in a strong uptrend for the past two years. Despite that, the trailing PE is only 6, and the share price is only a hair above the book value. This seems to be a good buy at almost any time.
Wrap Up
Will the market quickly bounce up or will it churn and dip some more towards longer-term moving averages? While no one can be certain, moving into some defensive stocks with historically decent upsides – at least for the next 12 weeks – might give you the peace of mind to jump back in when the collective mood improves.
Disclosure: I have no positions in any stocks mentioned, and no plans to initiate any positions within the next 72 hours.

text: avoid this place at all costs. Landlord is never there, repairs are never done. the majority of the residents are elderly and not friendly at all, the rooms are falling apart, just like the building itself, all in all slum housing. I would not rent a room from this over priced place. at 100 a week you could get a motel room for that price.. in better condition... the rooms in the place are extremely cramped... great for a person that has no posssesions.... but... Stay away from this place!!!

Equestrian joins elite club honoring senior riders and horses
John Fitzgerald of Hakalau was inducted into a special group of senior dressage riders and horses in February at a horse show in Hilo. The ages of Fitzgerald and his horse, Smoke, qualify them to become members of The Dressage Foundation's Century Club.
The Century Club recognizes dressage riders and horses whose combined ages total 100 years or more. John is 72, and Smoke is 32. In addition to having ages totaling 100 or more, horse and rider perform a dressage test of any level at a dressage show and are scored by a dressage judge. The Dressage Foundation provides a Century Club ribbon and wall plaque to each horse and rider team. Local dressage clubs, family and friends help to make the ride into a celebratory event.
The Century Club was formed at The Dressage Foundation in 1996, at the suggestion of noted dressage judge and instructor Dr. Max Gahwyler. The intent was to encourage older dressage riders to remain active in the sport. Since that time, the Century Club has grown into a meaningful and popular endeavor and has more than 150 members.
Riders from across the country are members of the Century Club, but Fitzgerald is only the third member from Hawaii.
Dressage is a word drawn from the French verb for "to train." Dressage is both a method of training horses and a competitive sport, and is designed to develop correct movement in the horse.
For more information about The Dressage Foundation or the Century Club, contact Jenny Johnson, administrative director, at (402) 434-8585 or visit www.dressagefoundation.org.
