Drexel University is a private research university with three campuses in Philadelphia and one in Sacramento, California. It was founded in 1891 by Anthony J. Drexel, a noted financier and philanthropist. Drexel offers over 70 full-time undergraduate programs and accelerated degrees. At the graduate level, the university offers over 100 masters, doctoral, and professional programs, many available part-time.Drexel is best known for the cooperative education program . Drexel's co-op is regularly ranked as one of the best co-op programs in the United States. Participating students have a variety of opportunities to gain up to 18-months of paid full-time working experience before graduation. The university has a large network of more than 1,600 corporate, governmental, and non-profit partners in 28 states and 25 international locations. The employers include top ranked multinational law firms, banks, corporations, and many Fortune 500 companies, such as Goldman Sachs, Microsoft, and Procter & Gamble.Shanghai Jiao Tong University’s academic ranking of world universities ranks Drexel 401-500 and Times Higher Education World University Rankings placed Drexel among the top 200 universities in the World. In U.S. News & World Report's annual "America's Best Colleges List", the university has been ranked consistently among the "Best National Universities – Top Schools." The 2012 rankings place Drexel third in their list of “Up and Coming National Universities” for "promising and innovative changes in the areas of academics, faculty, and student life." In addition, the National Science Foundation and the 2009 Lombardi Report also ranked Drexel among the top 50 private comprehensive research universities. Drexel University ranks #45 among "Research Universities by Salary Potential" in the United States. Wikipedia.

A system for measuring structural integrity includes a self-contained rapid modal testing trailer that delivers an impact load to a structure being tested and records data resulting from the impact load, and a data processing software that extracts modal parameters of the structure, such as frequencies and mode shapes. The parameters are used to determine anomalous behavior as well as provide experimental data for finite element model calibration.

Grafted triglycerides prepared from an epoxidized triglyceride and an acid anhydride containing 4 to 40 carbon atoms are reacted with an epoxy resin and an anhydride curing agent to yield an epoxy thermoset. By varying the length of fatty residues on the grafted triglyceride, the number of fatty residues per triglyceride, the identity of the epoxy resin and the anhydride curing agent, it is possible to prepare epoxy thermosets that exhibit superior physical properties compared to the properties of epoxy thermosets prepared without the grafted triglyceride, or as compared to epoxy thermosets wherein the epoxidized triglyceride is used in place of the grafted triglyceride. A significant improvement in fracture toughness with a minimal reduction of glass transition temperature may be thus achieved.

A PEFS (Piezoelectric Finger Sensor) acts as an electronic finger capable of accurately and non-destructively measuring both the Youngs compression modulus and shear modulus of tissues with gentle touches to the surface. The PEFS measures both the Youngs compression modulus and shear modulus variations in tissue generating a less than one-millimeter spatial resolution up to a depth of several centimeters. This offers great potential for in-vivo early detection of diseases. A portable hand-held device is also disclosed. The PEF offers superior sensitivity.

A sensing method is based on using a special fiberoptic probe for detection of acoustic/ultrasound pressure in an immersion medium. The developed system is highly sensitive in detecting ultrasound waves up to 100 MHz, for imaging of micro structures and more. For applications up to 100 MHz, without spatial averaging corrections, the probe tip is modified by reducing the fiber diameter to 7 um or less. Also, to maximize acousto-optic interaction, the probe tip, not just its end face, may be coated with a thin layer of metallic material. This thin film coating satisfies partial transparency of the metallic coating. The coating thickness may range from 2 nm to 10 nm or others depending on the type of the coating material. The probe detects the pressure of acoustic and/or ultrasound waves propagating within an immersion medium, whenever the probe tip is immersed inside the medium, and having a reasonable immersion contact surface.

Described herein is a new holographic polymer dispersed liquid crystal (HPDLC) medium with broadband reflective properties, and a new technique for fabrication of broadband HPDLC mediums. The new technique involves dynamic variation of the holography setup during HPDLC formation, enabling the broadening of the HPDLC mediums wavelength response. Dynamic variation of the holography setup may include the rotation and/or translation of one or more motorized stages, allowing for time and spatial, or angular, multiplexing through variation of the incident angles of one or more laser beams on a pre-polymer mixture during manufacture. An HPDLC medium manufactured using these techniques exhibits improved optical response by reflecting a broadband spectrum of wavelengths. A new broadband holographic polymer dispersed liquid crystal thin film polymeric mirror stack with electrically-switchable beam steering capability is disclosed.

Motor primitives allow integration across scales in the motor system and may link movement construction and circuit organization. This review examines support for primitives, and new data relating primitives to concrete circuit elements across species. Both kinematic motor primitives and muscle synergy/kinetic motor primitives are reviewed. Motor primitives allow a modular hierarchy that may be re-used by volitional systems in novel ways. They can provide a developmental bootstrap for ethologically important actions. Collections of primitives somewhat constrain motor acts, but at the same time sets of primitives facilitate the rapid construction of these constrained actions, and can allow use of simpler controls. Novel motor skill likely requires augmentation to transcend the constraints present in initial collections of low level motor primitives. The benefits and limitations of motor primitives and the recognized knowledge gaps and needs for future research are briefly discussed. © 2015 Elsevier Ltd.
