The development of a nondestructive, full-field, quantitative optical technique, and its feasibility to study dynamic deformations of opaque and diffusively reflecting solids under transient loads, are discussed. The technique involves recording a sequence of dynamically changing two-beam speckle interference patterns (also called holographic speckle patterns) of a rapidly deforming body which is doubly illuminated by a laser light source. The time sequence of speckle patterns is recorded by means of a high-speed camera on an ultra-sensitive 35-mm film. The developed negatives are then digitized by a CCD camera into an image processing system. An initial speckle pattern corresponding to the undeformed state of the object is taken as the reference, and subsequent speckle patterns are digitally subtracted (reconstructed) from it to produce time-varying fringe patterns corresponding to the relative deformation of the test object. In order to gain confidence that the technique can be used to record truly transient deformation, it is tested here on a vibrating plate at resonance, thereby obtaining the evolution of the fringe pattern during 1/2 cycle of deformation corresponding to 160 µs.

Habeas Hard Drive was dismayed at the ruckus that unfolded in North Las Vegas earlier this month, when the retiring police chief revealed some details from a six-month-old child porn investigation. Police had responded last fall to Mayor John Lee's report that he found images on his iPad he believed to be child pornography.

The construction industry is has been around for centuries in this country industry with that much inertia does not embrace change easily. Introducing new processes and methodology is much like trying to turn an aircraft carrier with a boat oar. You can get beat up pretty good and not even effect the ship!

Addiction to opioid analgesics is an important and yet underinvestigated clinical issue, which has substantial implications in opioid therapy for chronic pain management. Problematic opioid use, including compulsive opioid seeking and addiction, arises in some fraction of opioid-treated chronic pain patients. The connection between chronic pain and opioid addiction is a complex interplay between psychological, epidemiological, and neurobiological factors. Herein, we explore this critical relationship.

Most contractors know that the mechanic's lien is one of the best remedies available to the contractor, laborer, and supplier because it allows for the foreclosure of real property if payment is not made for construction work and/or materials supplied to the project. What many contractors may be unsure of is on which projects a lien should be recorded.

In Part 1 of this three-installment series, I characterized the development of MCI's new ramp-equipped accessible motorcoach (the MCI D45 CRT LE) as a "paradigm shift." While I will expand on why this is so in the third and last installment next month, this installment will overview the most unique features of this remarkable vehicle -- a vehicle whose ultimate potential I feel has not yet been realized.

It's a no-brainer; the financial industry has changed a lot over the last decades. There are multiple causes. Among the structural factors, one can mention the rise of technology, the decimalization and electronification of exchanges, the introduction of ECNs for equity, the increases in volume and speed of those exchanges. There were also significant regulatory changes (MiFID, Basel, Dodd-Frank...). Derivatives trading has changed a lot too. But what happened to the VIX on February 5th, could be a wake-up call to the industry and generate another wave of deep changes.

As I explained in IP Finance last week, following President Trump's blocking of Broadcom's hostile bid to acquire Qualcomm, by remaining independent the cellular technology leader will be able to maintain its long-term commitment to high levels of R&D investment (at 23 percent of sales recently), most significantly including that in 5G communications standard-essential IP.

Have you been keeping up with the “Amazon Effect” on supply chains? This effect is defined as the impact the digital marketplace has on the traditional business model in retail. But for supply chain professionals, it is so much more.

One is frequently presented with an individual who presents for evaluation as a result of traumatic events such as sexual harassment, sexual abuse in the school and workplace, electrical injury, and Traumatic Brain Injury.
