Assessing vibrating viscometers in slurries
A number of vibrating transducers for viscosity measurement described in the literature have been evaluated, with a view to developing an instrument for measuring gold-mine slurries. Appropriate electronic measuring methods are discussed, and related theory using a simple mathematical model is …

Vibrating transducers for fluid measurements
… The high degree of stability achieved for these vibrating structures was later realised in a different geometry. In this, a long rod was excited into a torsional mode so as to produce two nodes a quarter wavelength from. either end. By securing the rod at these points and immersing the lower …

Drag coefficients of vibrating synthetic rope
… tension, diameter and length of synthetic ropes vibrating because of vortex-induced forces, and net vibrating at different tensions were measured. Photographs were taken of the vortices. Drag coefficients were calculated and plotted against Reynolds Number. The measured frequency is compared with …

Fluid effects in vibrating micromachined structure
This thesis presents the study of the fluid damping and surfboarding effects for the tuning fork gyroscope. The quality factors in the drive and sense axes will be evaluated and compared with the experimental results for a range of pressures. The effects of the holes and the proof mass thickness …

Vibrating Existence: Early Cinema and Cognitive Creativity
This thesis collects together technical, historical and neurological evidence to examine how our perceptual and cognitive experience of cinema has changed diachronically and especially as a result of the transition from analogue to digital cinema projection. The slow arrival but sudden dominance of …

Boundary condition effects on vibrating cantilever beams
… Buckingham Pi theory the dynamic behavior of the vibrating beams could be quantified and the associated variables used to tailor the design of a flexure and boundary control system. This research details the primary correlation between variables in a flexure system during natural frequency …

An integral equation approach to vibrating plates
A knowledge of the natural frequencies of a vibrating plate is of great importance if an effective design is to be made which will prevent critical conditions of heavy vibration from occurring. Those frequencies which are associated with the symmetric modes are especially important. Many …

Characterisation of thick liquids using a vibrating transducer
This report describes in detail all the work carried out to reach the main objective of this thesis project, which is to develop a tuning fork into a portable instrument used for the characterisation of thick liquids based on their density and viscosity.

Strain-deflection relationships of freely vibrating wood beams
… flexural strain and midspan deflection of freely vibrating wood beams with various end conditions. Theoretical strain-deflection relationships of freely vibrating wood beams with pinned-end and fixed-end conditions were derived from vibration theory. Free vibration tests on three wood beams with …

Droplet Rebound and Atomization Characteristics of Vibrating Surfaces
… this study focuses on droplets impacting the vibrating surface at frequencies between 2-7 kHz. Atomization (water drop splitting into smaller droplets and ejecting from the surface) has been observed at different rates for all frequencies. The first set of data is collected by keeping …

Vibrating the Web: Sonospheric Studies of Media Infrastructure Ecologies
How can the relationship between media infrastructures and the economies of noise foster the development of a sonospheric art practice? Media infrastructures are the material backbone of the Internet. Such sites underpin the digitally hyperconnected world, but as material assemblages are also …

A study of vibrating-rotating motions of polyatomic molecules
Exact vibration-rotational eigenstates for the ground electronic state of HCN were obtained by solving the time-independent Schrodinger equation. The Hamiltonian of the system was expressed in both rectilinear and curvilinear coordinates, Potential energy surfaces were obtained from fitting either …
