Bones, particularly long ones, are among the most fascinating and intriguing materials, not only because of the complicated structure, but also because of their mechanical behavior, which is still not completely understood.Finite Element computer simulations of the modal behaviour of human femur were compared to experimental results of the resonance frequencies of actual bones, indicating that ...

We present high-resolution optical spectra of EUV-selected late-type stars. We have detected seven new spectroscopic binaries, including a pair of F stars and an RS Canum Venaticorum candidate. Many of the stars in our sample show remarkable H emission with equivalent widths up to 8 Å. Several sources show strong He i 5876 Å emission. We use cross-correlation techniques to estimate line-of-sigh...

[1] Understanding and quantifying the multiscale interactions between surface shear stress and velocity in the boundary layer is essential to improving boundary condition parameterizations used in numerical models of turbulent boundary layers. In this study, high-frequencymeasurements obtained in a wind tunnel are used to identify dominant scales of interaction (quantified in terms of scale-dep...

An increasingly urgent topic for the realization of densely packed (mixed signal) integrated circuits is prevention of cross-talk via the substrate. Due to decreasing distances between components and increasing operating frequencies, the coupling between components and/or circuit blocks becomes stronger and affects the circuit behaviour more and more. This paper proposes a Boundary Element Meth...

Growth of consumer-faced information systems (IS) applications shifts IS designers from seeing their work as “capturing and automating requirements” to seeing it as “innovation in product development.” The new metaphor engenders organizational practices targeted at fostering innovation. One such practice is establishment of professionally and organizationally diverse development teams charged w...

the finite element method is employed for the flexural-torsional linear buckling analysis of beams of arbitrarily shaped composite cross-section taking into account generalized warping (shear lag effects due to both flexure and torsion). the contacting materials, that constitute the composite cross section, may include a finite number of holes. a compressive axial load is applied to the beam. the...

To achieve the vision of E-government organizations across the federal, state, and local government are challenged to improve efficiency and effectiveness, and to afford citizens the same access to information and services they have come to expect from E-business. E-government also has the potential to foster participation in governance. To achieve E-government objectives, leaders must collabor...
