We examine if vibration of millimeter-sized cantilever sensors can release nonspecifically adsorbed proteins. Integrated electrochemical and mass-change measurement as well as fluorescence assays showed transverse surface vibration released nonspecifically bound proteins in samples prepared at 0.2-3.6 mg bovine serum albumin (BSA) per mL. Extent of release was directly related to magnitude of e...

Structural vibration testing might be a promising method to study the mechanical properties of spinal motion segments as an alternative to imaging and spinal manipulation techniques. Structural vibration testing is a non-destructive measurement technique that measures the response of a system to an applied vibration as a function of frequency, and allows determination of modal parameters such a...

A general model for a rotating homogenous j-lexible robot link is developed. The model describes twodimensional transverse vibrations induced by the actuator due to misalignment of the actuator axis of rotation relative to the link symmetry axis and due to translational acceleration of the link. The model is validated experimentally.

long wave side it appears that there may be some additional bands. The magnitude of this spacing indicates that we have to do with one of the transverse or "deformation" oscillations of the molecule, and the complexity of the bands is evidently due to the existence of several vibrational levels having nearly the same energy. In the case of the ideal linear, molecule with Hooke's law binding the...

The existing industrial parts feeders move the parts through a sequence of mechanical lters that reject parts in unwanted orientations. In this paper we develop a new setup that uses a di erent vibratory mechanism to systematically manipulate parts, by actively orienting and localizing them. The idea is to generate and change dynamic modes for a plate by varying the applied frequency of oscilla...

The main purposes of the present work are devoted to the investigation of the free axial vibration, as well as the time-dependent and forced axial vibration of a SWCNT subjected to a moving load. The governing equation is derived through using Hamilton's principle. Eringen’s nonlocal elasticity theory has been utilized to analyze the nonlocal behaviors of SWCNT. A Galerkin method based on a clo...

The vibration of the organ of Corti, a three-dimensional micromechanical structure that incorporates the sensory cells of the hearing organ, was measured in three mutually orthogonal directions. This was achieved by coupling the light of a laser Doppler vibrometer into the side arm of an epifluorescence microscope to measure velocity along the optical axis of the microscope, called the transver...

The Delaware Memorial Bridge is a major suspension bridge that is critical to the tri-state region of northern Delaware, southern New Jersey, and southeastern Pennsylvania. The Delaware Memorial Bridge consists of two nearly-identical suspension bridges (hence the nickname “Twin Spans”) that cross the Delaware River from southern New Jersey to northern Delaware. Field ambient vibration measurem...

In this study, the analysis of transverse vibrations of rectangular plate with circular central hole with different boundary conditions is studied and the natural frequencies and natural modes of a rectangular plate with circular hole have been obtained. To solve the problem, it is necessary to use both Cartesian and polar coordinate system. The complexity of the method is to apply an appropria...
