Liquivac pumps, with their unique shaped twin start helical rotor, have found utility in various sectors but the major drawback limiting global exploitation is low performance. This paper investigates study of performance pump produced by Tomlinson Hall Ltd. Experimental data was used to validate a numerical model developed Ansys Fluent 20.2 for pump. Four different geometric models rotor were ...

Multi-sensor networks provide complementary information for various tasks like object detection, movement analysis and tracking. One of the important ingredients for efficient multi-sensor network actualization is the optimal configuration of sensors. In this work, we consider the problem of optimal configuration of a network of coupled camera-inertial sensors for 3D data registration and recon...

The techniques developed by Butscher in [4] for constructing constant mean curvature (CMC) hypersurfaces in S by gluing together spherical building blocks are generalized to handle less symmetric initial configurations. The outcome is that the approximately CMC hypersurface obtained by gluing the initial configuration together can be perturbed into an exactly CMC hypersurface only when certain ...

We examine the turbulence driven by ion and electron temperature gradients in selected magnetic configurations of Wendelstein 7-X (W7-X) stellarator. The inherent flexibility configuration space W7-X enables us to find candidate manifesting low turbulent transport. follow insights gained stellarator optimization techniques, order identify key geometric features, which are directly related heat ...

An aerodynamic shape optimization method that treats the design of complex aircraft configurations subject to high fidelity computational fluid dynamics (CFD), geometric constraints and multiple design points is described. The design process will be greatly accelerated through the use of both control theory and distributed memory computer architectures. Control theory is employed to derive the ...

Hip fractures due to osteoporosis are accompanied with increased mortality and morbidity. Bone mineral density (BMD [g/cm(2)]) measured by dual-energy X-ray absorptiometry (DXA) is the most important risk factor. However, an overlap exists between results of fractured and nonfractured populations. Macro-architectural parameters of the femur are independent risk factors of fracture. They have be...

This paper begins by extending the notion of a combinatorial configuration points and lines to planes that we refer as configurations order $2$. We then proceed investigate further extension $k$-planes ($k$-dimensional hyperplanes) which $k$. present number general examples such stacked $k$ - intuitively layering lower product discuss many analogues standard dual configurations, isomorphisms, g...

We have investigated the combined effect of tissue heterogeneity and its variation associated with geometric error in stereotactic body radiotherapy (SBRT) for lung cancer. The treatment plans for eight lung cancer patients were calculated using effective path length (EPL) correction and Monte Carlo (MC) algorithms, with both having the same beam configuration for each patient. These two kinds ...

We describe a general construction of geometric U-folds compatible with the global formulation of four-dimensional extended supergravity on a differentiable spin manifold. The topology of geometric U-folds depends on certain fiber bundles which encode how supergravity fields are globally glued together. Smooth non-trivial U-folds of this type can exist only in theories where both the scalar and...

For a flexible tension structure, the first thing to do is perform form-finding analysis obtain reasonable initial state of structure. The includes structure's own weight and cable force distribution under additional dead load corresponding geometric configuration. configuration expectations must be ensured consistent with geometry building. This paper used MIDAS software establish zero-state m...
