Cam – clamping device with variable eccentricity

Experimental Control of Variable Cam Timing Actuators

In this paper, we propose a control scheme for the position of Variable Cam Timing (VCT) actuators. We take into account the observation by (Genç et al., 2001) that these actuators feature a significant nonlinearity, but we use a different approach. We perform a model reduction of mechanics, pressure, flows and balance equations. It serves to design an observer used in a motion planning strateg...

Variable Clamping Force Control for an Inteligent Fixturing

An Intelligent Fixturing System (IFS) is currently being developed to hold a family of thin-walled workpieces for machining operations. This is a cost-effective system which uses off-line optimisation of the clamps location and on-line adjustment of clamping forces. As adaptive clamping forces appropriate to the dynamic machining environment are employed, the IFS offers higher quality of machin...

Visual performance with changes in eccentricity in PROSE device: a case report.

This case report describes the variations in visual performance of a subject with moderate keratoconus with changes in front surface eccentricities (FSEs) of PROSE (Prosthetic Replacement of Ocular Surface Ecosystem). PROSE device of 0.6 FSE provided maximum visual improvement and reduction in Higher Order Aberrations (HOAs) compared to 0, 0.3 and 0.8 FSEs in this clinical condition.

PCR Clamping 27 PCR Clamping

An efficient, PCR based method for the selective amplification of DNA target sequences that differs by a single base pair is described. The method utilises the high affinity and specificity of PNA for their complementary nucleic acids and that PNA cannot function as primers for DNA polymerases.
