The University of Louisiana at Lafayette, or UL Lafayette, is a coeducational, public, research university located in Lafayette, in the U.S. state of Louisiana. It has the largest enrollment within the nine-campus University of Louisiana System and has the second largest enrollment in Louisiana.Founded in 1898 as an industrial school, the institution developed into a four-year university during the twentieth century and became known by its present name in 1999. Concurrently the university evolved into a national research and doctoral university as noted by its Carnegie categorization as a RU/H: research university . It offers Louisiana's only Ph.D. in francophone studies and Louisiana's only industrial design degree. The university has achieved several milestones in computer science, engineering and architecture. It is also home to a distinct College of the Arts. Wikipedia.

RNA viruses account for numerous emerging and perennial infectious diseases, and are characterized by rapid rates of molecular evolution. The ecological dynamics of most emerging RNA viruses are still poorly understood and difficult to ascertain. The availability of genome sequence data for many RNA viruses, in principle, could be used to infer ecological dynamics if changes in population numbers produced a lasting signature within the pattern of genome evolution. As a result, the rapidly emerging phylogeographic structure of a pathogen, shaped by the rise and fall in the number of infections and their spatial distribution, could be used as a surrogate for direct ecological assessments. Based on rabies virus as our example, we use a model combining ecological and evolutionary processes to test whether variation in the rate of host movement results in predictive diagnostic patterns of pathogen genetic structure. We identify several linearizable relationships between host dispersal rate and measures of phylogenetic structure suggesting genetic information can be used to directly infer ecological process. We also find phylogenetic structure may be more revealing than demography for certain ecological processes. Our approach extends the reach of current analytic frameworks for infectious disease dynamics by linking phylogeography back to underlying ecological processes. Source

The present invention is directed to a system and methods for treatment of biomass products or residues to obtain valuable adhesives and composite materials. Certain embodiments require no purification of a biomass product or residue to produce an adhesive. Certain embodiments include a treatment of post extraction algae residue configured to produce an adhesive. Advantageously, such use of post extraction algae residue adds value to alternative energy produced by extracting oil from algae.

An ultra dense and ultra low power microhotplates using silica aerogel and method of making the same, comprising creating a sol-gel by impregnation of ethanol with functional colloidal alcogel particles is described. The technique further comprises forming tiny aerogel particles on the wafer and networking the particles together just by exposure to air during spin coating. The novelty of this technique is not limited to the processing of thin film and thick film silica aerogel.

Motorized machinery, such as overhead cranes, are widely used in industries all over the world. It is not easy to move crane payloads without oscillation, increasing the likelihood of obstacle collisions and other accidents. One possible solution to such problems could be aiding the operator with a dynamic map of the workspace that shows the current position of obstacles. This method discloses the use of a camera to take images of the workspace, using imaging blurring to smooth the obtained images, and drawing contours to produce an individual, near real-time map of the workspace. In one or more embodiments, known obstacles may be tagged in a manner which is readable by the camera. This image and historical images of the same workspace are layered on top of one another to produce a map of obstacles on the workspace floor. This imaging and layering can produce a near real-time map of obstacles that can be used to guide heavy motorized machinery around a workspace without incident.


The present invention relates generally to a system and methods for testing sensitization of alloy nondestructively. More specifically, the present invention relates to a system and methods for determining the sensitization of an alloy by measuring ultrasonic parameters of the alloy using ultrasonic techniques, and correlating the measured ultrasonic parameters. In certain embodiments, the ultrasonic measuring techniques include pulse-echo and resonant ultrasound spectroscopy. Certain embodiments use ultrasonic measuring techniques to measure shear-wave velocity, compressional-wave velocity, and attenuation coefficient of compressional waves. One preferred embodiment correlates measured ultrasonic parameters including shear-wave velocity, compressional-wave velocity, and attenuation coefficient of compressional waves to determine the sensitization of alloy. Advantageously, certain embodiments of the invention make it easier to collect, store, and correlate measured ultrasonic parameters through use of a computer system.
