The history of humeral component design has evolved from prostheses with relatively long stems and limited anatomic head options to a contemporary platform with short stems and stemless implants with shared instrumentation and the ability to provide optimal shoulder reconstruction for both anatomic and reverse configurations. Contemporary humeral components aim to preserve the bone, but they are potentially subject to malalignment. Modern components are expected to favorably load the humerus and minimize adverse bone reactions. Although there will likely continue to be further refinements in humeral component design, the next frontiers in primary shoulder arthroplasty will revolve around designing an optimal plan, including adequate soft tissue tension and providing computer-assisted tools for the accurate execution of the preoperative plan in the operating room.

Advanced Technology turbine components have been developed for the GE MS5002 line of gas turbines that permit operation at a higher firing temperature. Those components include directionally solidified (DS) GTD-111 alloy stage-one buckets — the first GE application of a DS alloy in heavy-duty gas turbines. The Advanced Technology uprate improves turbine performance and extends turbine inspection intervals. This paper provides an overview of the field modification of 21 mechanical drive units in Indonesia. The user’s technical objectives and uprate requirements are discussed along with installation experience and operating results to date. Advanced Technology component design features are illustrated and discussed in some detail with reference to their application in field units.

Abstract A method for determining the effect of suspension dynamics on tire wear has been developed. Typical city cycle maneuvers are defined by instrumented vehicle testing and data in the form of forward velocities and steer angles are used as an input to an ADAMS computer model of the vehicle. A simulation of the maneuvers generates a tire's operating environment in the form of normal load, slip, and camber variations, which contain all the subtle effects of the vehicle's suspension, steering, and handling characteristics. A cyclic repetition of the tire's operating environment is constructed and used to control an MTS Flat-Trac machine. In this way, accelerated tire wear can be generated in the laboratory which is directly related to the design features of the vehicle's suspension and steering systems.
