Though remarkably robust, articular cartilage becomes susceptible to damage at high loading rates, particularly under shear. While several studies have measured the local static and steady-state shear properties of cartilage, it is the local viscoelastic properties that determine the tissue's ability to withstand physiological loading regimens. However, measuring local viscoelastic properties r...

Off-road cars’ windshields are vulnerable to different types of stones, road debris and pebbles due to common off paved and gravel surfaces in which they drive. Any attempt to design windshield that minimizes injury and death of occupants during a vehicle accident requires a thorough understanding of the mechanical behavior of automotive windshield subjected to foreign object impact loads...

We report on the use of metal-insulator-semiconductor ~MIS! diodes, formed on n-GaN with SiO2 , for capacitive strain sensing. These diodes, when subjected to static strain, were found to exhibit a steady-state change in capacitance. As a result, they can be used to detect strain with frequencies all the way down to dc. We formulate a model to explain the action of piezoelectricity in the diode...

Lignin fiber/epoxy resin compositeused for energy absorbing was prepared by atmospheric stirring method. Quasi-static compressive mechanics tests were implemented using the electronic universal tester (WDW-100KN) under ambient conditions to analyze compressing behavior of matrix material and composite at strain rate 10-2s-1 .Scanning electron microscope (SEM) used observe microstructure after q...

Mechanical stresses experienced by packages in the distribution environment include shock and vibration amongst several others. The destructive effects of these hazards can typically be restricted by using cushioning materials to help protect fragile goods during distribution. ASTM D 1596 is the conventional standard used to determine shock absorbing performance of a cushioning material for a g...

I review the status of the calculations of the QCD static energy at short distances, including renormalization group and renormalon analysis. Applications to heavy quarkonium physics are briefly discussed. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.

In this paper we leverage an existing general framework for resource usage verification and specialize it for verifying energy consumption specifications of embedded programs. Such specifications can include both lower and upper bounds on energy usage, and they can express intervals within which energy usage is to be certified to be within such bounds. The bounds of the intervals can be given i...

A new Quasi-Static Energy Recovery Logic family (QSERL) using the principle of adiabatic switching is proposed in this paper. Most of the previously proposed adiabatic logic are dynamic and require complex clocking schemes. The proposed Quasi-Static energy recovery logic uses two complementary sinusoidal supply clocks and resembles behaviors of static CMOS. Thus, switching activity is signiican...

This study presents the experimental results for a series of tests on the uniaxial quasi-static crushing of cubical specimens of 50mm side for two species of wood such as Jack wood and Indian Fig. Compression tests were conducted on universal testing machine of 400kN capacity and at a constant deformation rate of 8mm/min. The woods were separately tested in the two principal directions i.e., gr...
