Localization and quantification of the light sources generated by the expression of bioluminescent reporter genes is an important task in bioluminescent imaging of small animals, especially the generically engineered mice. To employ the Monte Carlo method for the light-source identification, the surfaces that define the anatomic structures of the small experimental animal is required; to perfor...

Redundantly actuated Parallel Kinematic Machines (PKMs) offer a number of advantages compared to classical non-redundant PKMs. Particularly, they show a better stiffness thanks to singularity avoidance and they have an improved repeatability due to a better behavior against backlashes. The main problem with the calibration of these machines is that the redundancy leads to some mechanical strain...

Abstract As an approximate theory that is highly regarded for its computational efficiency, geometrical optics (GO) widely used modeling waves in various areas of physics. However, GO fails at caustics, which significantly limits applicability. A new framework, called metaplectic (MGO), has recently been developed allows caustics certain types to be modeled accurately within the framework. Here...

In time-domain simulations of sound propagation and/or scattering, it is possible to model the geometricalacoustics (GA) components and the edge-diffraction components separately and combine the results into a “total” impulse response. However, such separate calculations can limit the efficiency and accuracy of the simulations because the two components are not independent. This paper presents ...
