Radial inflow turbine meshing rev. 1
Get PDFThis report describes meshing utilities to support the mesh generation for Radial Inflow Turbines. This includes two tools: (a) parameterised mesh generator for Nozzle Guide Vanes; (b) a geometry and mesh generation tool for turbine rotors. A key feature of the turbine rotor mesh and geometry generation tool is that it allows a parametric definition of the geometry based on properties of the aerodynamic passage. For example desired flow direction and evolution of flow area. This is in contrast to alternative methods, which start by defining the physical features of the rotor (e.g. hub and shroud shape), in which case the aerodynamic passage becomes and output. In addition to providing the description of the two tools, usage instructions and examples are provided
A tethering complex recruits SNAREs and grabs vesicles.
Get PDFProtein tethers can bridge gaps between membranes. Ren et al. (2009) now provide evidence that the yeast Dsl1 complex tethers vesicles to the endoplasmic reticulum (ER) by binding ER SNARE proteins at its base and capturing vesicles using a loop region that extends 20 nm from the ER membrane
pfow.py a potential flow solver and visualizer
Get PDFpflow.py is a simple teaching and analysis tool for 2-D Potential Flows. It is a collection of code, that allows the construction of simple flow fields that meet the Potential Flow governing Equations. A range of plotting and visulisation tools are included
Quasi-exact-solution of the Generalized Exe Jahn-Teller Hamiltonian
Full text linkWe consider the solution of a generalized Exe Jahn-Teller Hamiltonian in the
context of quasi-exactly solvable spectral problems. This Hamiltonian is
expressed in terms of the generators of the osp(2,2) Lie algebra. Analytical
expressions are obtained for eigenstates and eigenvalues. The solutions lead to
a number of earlier results discussed in the literature. However, our approach
renders a new understanding of ``exact isolated'' solutions
