A radius at a root of the hub-side leading edge part is set in a boss ratio of 0 to 0.4.

A castable, moldable, and/or extrudable structure using a metallic primary alloy. One or more additives are added to the metallic primary alloy so that in situ galvanically-active reinforcement particles are formed in the melt or on cooling from the melt. The composite contain an optimal composition and morphology to achieve a specific galvanic corrosion rate in the entire composite. The in situ formed galvanically-active particles can be used to enhance mechanical properties of the composite, such as ductility and/or tensile strength. The final casting can also be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final composite over the as-cast material.

Novel aqueous, acid etch solutions comprising a fluorinated surfactant are provided. The etch solutions are used with a wide variety of substrates, for example, in the etching of silicon oxide-containing substrates.

A method for reducing the peak-to-average power ratio of the time-domain signal in a communication system using multi-carrier modulation is provided herein. The present invention is based on the method of recursive clipping and filtering to reduce the peak-to-average power ratio and out-of-band spectrum, but during the recursive process, the distortion of the multi-carrier modulated signal is controlled to be bounded within a specific region. In an additive white Gaussian noise channel with high signal-to-noise ratio, the present invention could achieve significantly lower error rate and the error floor phenomenon is almost completely removed. Therefore the power amplifier could be operated at higher average output power and a smaller range of linearity.

A method of adaptive local image similarity measurement based on the L₁ distance measure is described. A relationship between distance measures is used to estimate appropriate thresholds for various patch sizes. The choice of patch size depends on the degradations contained in the image and the application. The relation between the similarity measures is established using the distribution of L₁ distances for various patch sizes. For larger degradations, similarity measure with a bigger patch size is employed. For lesser imperfections, a smaller patch size produces acceptable results. To keep the computational overhead manageable, the smallest patch size that gives the desired image quality is employed.
