    Abstract: In software engineering, the performance or efficiency of individual process steps is typically defined as some sort of rate such as the number of detected defects divided by the effort spent for review or testing. In this situation, the variation in the data always reflects a mixture of intrinsic process variation caused by, for example, human factors such as the experience of reviewers or the variable quality of the review objects, and purely statistical variation due to the effects of Poisson statistics when defects are counted. Due to this mixture of causes of variation no conventional statistical process control chart holds for the constraints of typical software engineering processes. A new statistical process control (SPC) approach (method and system) is presented to overcome the mentioned problems.

    Abstract: A safety razor for wet shaving having two sets of blades cutting with opposite shaving stroke directions. This permits more efficient and effective shaving than with razors having blades that cut with strokes in one direction only.

    Abstract: A method and system for reducing stress corrosion cracking in a hot water system, such as a nuclear reactor, by reducing the electrochemical corrosion potential of components exposed to high temperature water within the structure. The method includes the steps of: providing a reducing species to the high temperature water; and providing a plurality of noble metal nanoparticles having a mean particle size of up to about 100 nm to the high temperature water during operation of the hot water system. The catalytic nanoparticles, which may contain at least one noble metal, form a colloidal suspension in the high temperature water and provide a catalytic surface on which a reducing species reacts with least one oxidizing species present in the high temperature water. The concentration of the oxidizing species is reduced by reaction with the reducing species on the catalytic surface, thereby reducing the electrochemical corrosion potential of the component.

    Abstract: Mixing a liquid solution in a container by rotating a pair of bar-shaped magnets in a coordinated pattern in which lines parallel to the axes of the bar-shaped magnets remain normal to one another, the magnets disposed in close proximity to and on opposite sides of the container a distance above the bottom of the container so that a magnetic mixing member is caused to rotate in the liquid about the same distance above the bottom of the container. Relative vertical movement of the magnets and the container generates a vortex-like mixing action throughout the container.
