OpenProp is an open-source code suite that can be used for the design, analysis, and fabrication of optimized propellers and horizontal-axis turbines. The numerical model is based on propeller lifting line theory, which is used in parametric design codes employed by the U.S. Navy as well as commercial designers. OpenProp is written in Matlab M-code, which is widely used in academia and industry...

-The Design Sensitivity Analysis and Optimization (DSO) tool, developed initially for sizing design application, has been extended to support shape design applications of structural components. The new capabilities including shape design parameterization, error analysis and mesh adaptation, design velocity field computation, shape design sensitivity analysis, and interactive design steps, are d...

We demonstrate a meaningful prospective power analysis for an (admittedly idealized) illustrative connectome inference task. Modeling neurons as vertices and synapses as edges in a simple random graph model, we optimize the trade-off between the number of (putative) edges identified and the accuracy of the edge identification procedure. We conclude that explicit analysis of the quantity/quality...

ipad gene is amongst key genes in shigella invasion, known as an antigen. pa20 protein of bacillus anthracic can be separated from native pa protein during the infection and can be found in the serum of the infected patients and make it possible to diagnose the disease. ctxb, a known immune adjuvant, enhances the immunogenicity and is mainly used for the production of recombinant vaccines as a ...

During maneuvers, propellers’ operation differs from their design due to strong modification of the wake field with respect straight-ahead motion. The consequent loads overstresses mechanical components shaftline, exacerbates propeller side effects and worsens overall efficiency. Therefore, analysis these situations in early phase is pivotal increase capabilities safety at sea. This task relies...

performance analysis of jet engines in various environmental conditions is important and is the first step in the design of such engines. in this paper, the performance of a typical turboprop engine was modeled in the commercial software gasturb10 and the obtained results are validated at three flight regimes take off, military and 100% normal using engine test results. performance analysis of ...
