(Sound and Vibration Via Acquire Media NewsEdge) Random Vibration Course
A short course on "Random Vibration, Theory and Experiment" will be presented at Texas Christian University, Fort Worth, TX, March 12-14. The course will focus on: fundamentals of structural dynamics; fundamentals of probability, statistics, and random signal analysis; and fundamentals of the theory of random vibration.
The lectures will be augmented with narrated videos from TCU laboratories covering deterministic structural dynamics and random vibration. Two hours of these instructional vibration experiments will be interspersed throughout the program to complement the lectures. Further, extensive instrumentation equipment owned by TCU, as well as additional test and evaluation hardware, will be on display throughout the program.
Instructors are: Pat Walter, professor of engineering at Texas Christian University and a consultant, and Tom Paez, retired distinguished member of the technical staff at Sandia National Laboratories and a consultant. Together, they have more than eight decades of experience in structural dynamics, dynamic measurements, and random vibration. Dr. Walter has taught at TCU for the past 18 years, and Dr. Paez taught graduate and undergraduate-level courses for seven years at the University of New Mexico.
The course objectives are:
* To provide a thorough and understandable review and introduction to the elements required to comprehend random vibration: (a) measurement procedures, (b) linear structural dynamics, (c) theories of probability, statistics, and random signal analysis.
* To provide a thorough and understandable introduction to the theory of random vibration.
* To augment instruction with numerous examples and narrated laboratory videos.

Mathematics in Industry
The Society for Industrial and Applied Mathematics (SIAM) is pleased to announce the release of its latest report on Mathematics in Industry. Mathematical and computational sciences have many applications in industry, some that have dramatic effects on the bottom line of companies, and others that simply allow organizations to function efficiently in the 21st-century data-rich marketplace. A newly developed technology is not confined to the group or company that designs it but contributes to the enrichment of science as a whole.
Mathematical scientists in industry work in interdisciplinary team environments, with mathematical methods and successes often attributed to the larger dominant discipline of the team or research group. The goal of this report, which was funded by the National Science Foundation, is to underscore the essential role of mathematics in these diverse disciplines, and to help raise awareness of the value of mathematics in industry. The report is a combination of focus group meetings with industrial scientists, online surveys of recent doctoral degree recipients, and on-site interviews with more than 50 senior scientists and managers from dozens of corporations. It includes insights from a total of 145 mathematical and computational scientists, encompassing a broad range of professions and disciplines.
The centerpiece of the report is a set of case studies developed through interviews with scientists from 14 major industrial sectors, and describing various applications including business analytics and optimization, manufacturing design and virtual prototyping, quantitative drug design, financial risk analysis, production planning and supply chain management, and information retrieval and data mining. Students wanting to learn about the various applications of mathematics, educators attempting to prepare them for non-academic jobs in the field, and industry professionals seeking to explain the significance of mathematical methods will find value in this report. In addition to exploring the skills and traits that are needed to succeed in the fast-paced, multidisciplinary, production-oriented environment in industry, it emphasizes the need to better connect academic, government, and industrial scientists, and match education to the real- world demands of the workplace. A PDF file of the report is available at: www.siam.org/reports/mii/2012/.

Qualmark Corporation, a provider of HALT/HASS (highly accelerated life test/ highly accelerated stress screen) products and services, has announced agreements with Taylor- Wharton and Midwest Cryogenics that will provide HALT/HASS customers with convenient, one-stop shopping when adding accelerated stress testing to their reliability program.
A key advantage of HALT and HASS is the ability to perform rapid thermal ramps which cannot be achieved by the refrigeration system used in typical environmental stress screening equipment. Liquid nitrogen (LN2) is used in HALT/HASS systems to provide advanced thermal capabilities. Reliable and efficient liquid nitrogen (LN2) delivery supports optimum system performance and test results. Qualmark has signed agreements with leading cryogenic storage provider, Taylor-Wharton, and vacuum jacketed (VJ) pipe manufacturer, Midwest Cryogenics, to provide customers with one point of contact for all of their HALT/HASS needs, including LN2 infrastructure.
Taylor- Wharton is one of the largest providers of cryogenic tanks in the world with manufacturing facilities in the US, Europe and Asia that can support the ongoing global expansion of HALT/HASS. "We are pleased to be cooperating with Qualmark and Midwest Cryogenics to provide world class products and services to the growing number of companies utilizing LN2 for accelerated testing applications" stated Len York, president of Taylor-Wharton Cryogenics.
Midwest Cryogenics designs, manufactures and installs stainless steel superinsulated VJ piping for the efficient and cost-effective transport of LN2 to HALT/ HASS systems. "It's exciting to be a part of this partnership and expand our involvement in the HALT/HASS industry with high quality partners," said Paul Trcka, president of Midwest Cryogenics.
The new relationships pair Qualmark's top selling Typhoon series of HALT/HASS systems and breakthrough QFusion HASS system with select world class LN2 storage and delivery system providers. "Our relationships with Midwest Cryogenics and Taylor Wharton allow us to deliver best-inbreed HALT/HASS systems, VJ piping, and cryogenic tanks to our customers around the world. Our customers can elect to purchase all items on a turnkey basis from Qualmark with a single purchase order, or individually, as may be best for their organization," said Andy Drenick, CEO of Qualmark.

PCB Supports Mythbusters
PCB Piezotronics, Inc., a manufacturer of microphones, vibration, force, torque, load, strain, and pressure sensors, as well as the pioneer of ICP® technology is pleased to announced an agreement to supply The Discovery Channel's popular science series Mythbusters with test sensors for various episodes. The show hosts, special effects experts Adam Savage and Jamie Hyneman, use elements of the scientific method to test the validity of rumors, myths, movie scenes, internet videos and news stories. PCB Piezotronics has provided sensors to the Discovery Channel's Mythbusters show since 2005.
Episodes featuring PCB® sensors include "Dumpster Diving" where a crash test dummy is instrumented with PCB model 356 A02 triaxial ICP piezoelectric accelerometers to measure impact shock levels induced by a "typical" four-story jump into a dumpster filled with trash, to determine the probability for survival and test the myth commonly seen in getaway scenes of action movies where the action hero hops out after the fall and escapes from the villain. More recently, these PCB accelerometers made an appearance in the "Bubble Pack Plunge" episode, where Savage and Hyneman test the internet video myth that you can jump horn a height of 35 feet wrapped in bubble packaging and survive.
PCB® Series 102 pressure sensors have appeared in the "Toilet Bomb" and "Valkyrie Boom" episodes, both based on scenes from popular movies. The Series 137/138 blast probes assisted in "Depth Charge Disaster" To view these and all the Mythbusters episodes, go to www.discovery.com/mvthbusters
