We describe a simple modification to a rigid endoscope so as to provide both high-quality conventional and confocal images of reasonably accessible regions of the body. This versatile system uses a structured illumination approach together with a conventional incoherent illumination source. Images taken in fluorescence are presented using this combined conventional and confocal endoscope.

For rotordynamic analysis of hydropower units, the generator is treated as a rotating rigid body. However, previous studies have confirmed that certain designs generators are elastic, so complex geometry cannot be considered rigid. This work produced model with floating rotor rims, consisting hub and flexible rim coupled connections. The takes into account influence centrifugal Coriolis effects...

Researchers have found that rigid dietary control is connected to higher psychological distress, including disordered and disinhibited eating. Two approaches have been touted by certain scholars and/or health organizations as healthier alternatives: intuitive eating and flexible control-yet these approaches have not been compared in terms of their shared variance with one another and psychologi...

Weakly convex polyhedra which are star-shaped with respect to one of their vertices are infinitesimally rigid. This is a partial answer to the question whether every decomposable weakly convex polyhedron is infinitesimally rigid. The proof uses a recent result of Izmestiev on the geometry of convex caps.

The component-based model of a novel ductile connection has been incorporated into the software Vulcan in order to facilitate global frame analysis within performance-based structural fire engineering design process. This paper reports on validation and verification model, as well applications investigate effects connections responses long-span frames at high temperature. Firstly, three single-...

1 Motivation Over the years of human history, man-made systems reached higher and higher levels of complexity, as we wanted them to perform more and more complicated tasks. The predominant way humans use to build their machines is to construct them as more or less rigid structures of modules, each performing a predeened task, with a minimal number of connections between modules. In fact, this m...

We develop tools for studying the control of underactuated mechanical systems that evolve on a configuration space with a principal fiber bundle structure. Taking the viewpoint of affine connection control systems, we derive reduced formulations of the Levi-Civita and the nonholonomic affine connections, along with the symmetric product, in the presence of symmetries and nonholonomic constraint...

Steel plate shear walls (SPSWs) are a robust lateral load resistance structure because of their high ductility and efficient energy dissipation when subjected to seismic loads. This research investigates the performance an innovative infill web strip (IWS-SPSW) typical unstiffened steel wall (USPSW). As result, two 1:3 scale specimens IWS-SPSW USPSW with single story bay were built cyclic loadi...

The author has published equations for predicting the air borne sound transmission of double leaf cavity walls due to the structure borne sound transmission across the air cavity via (possibly resilient) line connections, but has never published the full derivation of these equations. The author also derived equations for the case when the connections are rigid point connections but has never u...
