in this paper, a new non-contact ultrasonic abrasive finishing mechanism is designed and fabricated. this mechanism combines the function of ultrasonic vibrations and the magnetic abrasive finishing (maf) process. a permanent magnet which is mounted on a horn has been used as the processing tool. this polishing tool is vibrated at an ultrasonic frequency with piezo-electric actuators. ultrasoni...

There has been a shortfall in the number of nurses, so it is required to optimize the nursing service. Then, the authors proposed a new system design for automated time study of nursing to investigate nursing service easily. The system combines images from video monitoring and information from ambient sensing, and it analyzes them after combining. Besides the authors conducted video monitoring ...

In 1994, a Ph.D-study started regarding pharmacy, organization and management (APOM) in the Netherlands. The APOM-project deals with the structuring and steering of pharmacy organization. This article describes the summary of the empirical results of a survey in a relatively large sample (n=169). Generalization to the population of pharmacies in the Netherlands was made. The results for thought...

The main aim of the present study was to investigate the extent to which East Franconian speakers neutralize the voicing opposition in intervocalic stops when they produce a variety of Standard German. A second aim was to test whether young and old speakers differ in their extent of neutralization and tend to a more standard-like pronunciation. We analyzed contrast maintenance by means of the v...

In this study, nonlinear vibration of a composite cable is investigated by considering nonlinear stress-strain relations. The composite cable is composed of an aluminum wire as reinforcement and a rubber coating as matrix. The nonlinear governing equations of motion are derived about to an initial curve and based on the fundamentals of continuum mechanics and the nonlinear Green-Lagrangian stra...

Forest management planning decisions are often based on the forest owner’s goals, which typically focus on economic criteria. Logging operation work productivity functions are used when costing forest operations. These functions affect the conclusions drawn during forest management analyses because different logging environments give rise to different harvesting costs. When evaluating new combi...
