The method, system and computer program product for design analysis of a component efficiently subject a finite element model of the component to the appropriate thermo-mechanical environment, evaluate the component’s stress responses to the environmental loads, and compare the stress responses to pre-selected limits. A wheel is positioned within the downwardly facing recess, and a wheel retainer arrangement is secured to the support member at the outwardly facing end opening. The grip body has at least first and second illumination sources and at least one laser emitter. The difference data are used with the native data to create a replica of the original data. The design of the spinal disc annulus stent allows ingrowth of normal cells of healing in an enhanced fashion strengthening the normal reparative process. The intermediate masks are produced by shifting a shift template by amounts corresponding to offsets of set bits in an existing output mask.
