BACKGROUND To compare the effectiveness of pelvic floor training (PFT) with the aid of a home biofeedback device to PFT alone for urodynamic stress urinary incontinence (SUI) in women after a 1-year follow-up. METHODS A randomized study comparing two conservative interventions was conducted in an outpatient clinic of a university hospital. Thirty-five… (More)
OBJECTIVES To compare electromyography-assisted biofeedback training to pelvic floor muscle training (PFMT) alone in patients with female stress urinary incontinence. METHODS A prospective randomized pilot study was conducted between March 1998 and February 2000 at the university hospital for outpatient care. Participants were women with urodynamically… (More)
—Traction motor design significantly differs from industrial machine design. The starting point is the load cycle instead of the steady-state rated operation point. The speed of the motor varies from zero to very high speeds. At low speeds, heavy overloading is used for starting, and the field-weakening region also plays an important role. Finding a… (More)
Often, the components of a pumping system are not selected from the perspective of the total system, as the individual components are selected using different programs. In this paper, a selection tool that optimizes the energy conversion efficiency of a pumping system according to actual process requirements is introduced. The tool requires only the catalog… (More)
Energy efficiencies of different hybrid systems are investigated in an urban bus cycle. A diesel bus is converted into a multihybrid bus also capable of operating in a direct diesel drive. The target is to investigate which kind of a hybrid system provides the lowest fuel consumption in different operating conditions.
