A virtual 'model' is generally a mathematical surrogate of a physical system and when well correlated, serves as a basis for understanding the physical system in part or in entirety. Drive Quality defines a driver's 'experience' of a blend of controlled responses to an applied input. The 'experience' encompasses physical, biological and bio-chemical perception of vehicular motion by the human body. In the automotive domain, many physical modeling tools are used to model the sub-components and its integration at the system level. Physical Modeling requires high domain expertise and is not only time consuming but is also very 'compute-resource' intensive. In the path to achieving 'vDQP (Virtual Drive Quality Prediction)' goal, one of the requirements is to establish 'well-correlated' virtual environments of high fidelity with respect to standard test maneuvers. This helps in advancing many developmental activities from a Controls and Calibration aspect. Recently, machine/deep learning have proven to be very effective in pattern recognition, classification tasks and human-level control to model highly nonlinear real world systems. This paper investigates the effectiveness of deep learning…

Scientists at Texas A&M University are harnessing the combined power of organic nanomaterials-based chemistry and a natural product found in crustacean exoskeletons to help bring emergency medicine one step closer to a viable solution for mitigating blood loss, from the hospital to the battlefield.

 

Wafer-Level Microchannel Fabrication Process for Lab-on-a-Chip Devices

  • Magazine Article
  • TBMG-34761
Published 2019-07-01 by Tech Briefs Media Group in United States

Microchannels fabricated into a silicon-Pyrex wafer with a diameter of 75 m and total channel length of 40, 60, 80, or 100 mm — characterized by specialized microbeads within the channel — have been successfully created, tested, and used at NASA Goddard Space Flight Center. Designed to collect and separate amino acids towards finding the building blocks of life on other planets, this technology could be essential to many other lab-on-a-chip or microfluidic applications.

 

Stretchable Interlaced-Nanowire Film for Ultraviolet Photodetectors with High Response Speed

  • Magazine Article
  • TBMG-34588
Published 2019-06-01 by Tech Briefs Media Group in United States

Stretchable electronics, which can be stretched, deformed and wrapped onto nonplanar curved surfaces, have attracted much attraction due to their potential applications in wearable electronics, implantable biomedical devices, and artificial electronic skin. So far, many types of stretchable electronic devices have been developed including stretchable transistors, light-emitting diodes (LEDs), supercapacitors, photodetectors and sensors. Ultraviolet (UV) photodetectors have wide applications in crime investigation, biological analysis, fire monitoring, UV irradiation detection and many other applications as well.

Published 2019-06-01 by Tech Briefs Media Group in United States

Silicon nanoneedle patches are currently placed between skin, muscles, or tissues where they deliver exact doses of biomolecules. Commercially available silicon nanoneedle patches are usually constructed on a rigid and opaque silicon wafer. The rigidity can cause discomfort and cannot be left in the body very long.

Micro UV Aerosol Detector

Published 2019-06-01 by Tech Briefs Media Group in United States

The detection of aerosols within fluid samples can be accomplished by optical methods. Such methods are useful in detecting potentially harmful aerosols such as biological aerosols that may be present after a biological agent attack or industrial accident. It is well known that biological molecules fluoresce when excited by ultraviolet (UV) radiation. As a result, biological molecules in an aerosol sample can be optically detected by irradiating the sample with ultraviolet radiation and observing the fluorescence response. Since differing excitation wavelengths may be used to detect different classes of biological molecules, the excitation wavelength can be chosen to detect specific classes of biological molecules such as proteins, flavinoids, and metabolite products.
