A PC-based orthopedic rehabilitation system was developed for use at home, while allowing for remote monitoring from the clinic. The home rehabilitation station has a Pentium II PC with graphics accelerator, Polhemus tracker, and a novel Multipurpose Haptic Control Interface with its own Pentium board. This interface is used to sample patient's hand positions and to provide resistive forces usi...

Many surgical procedures are now performed using the techniques of minimally invasive surgery (MIS), in which the surgeon manipulates instruments inserted into the patients through small incisions. In MIS, the surgeon has no direct contact with internal body parts. Applying an optimal force and torque via the instruments is necessary to conduct an operation without causing any damage to the int...

alternative theoretical perspectives have been presented to explain internationally effective factors affecting immigration. for example, the orthodox explanation of migration is based on the concept of wage differentials as an important factor of international immigration. the world system approach declines to interpret theoretically international migration as a phenomenon between independent ...

The ATI collection is over 50 years old and was imaged from roll film. The collection has deteriorated over time and is in poor condition. DTIC has reproduced the best available copy utilizing the most current imaging technology. ATI documents ...

Ongoing DARPA-sponsored research in computer intrusion detection (ID) has produced emerging systems that exploit a variety of techniques such as network sniffing, filesystem checks and local host audit record inspection, or more complex correlations of distributed sensors’ various reports. This research has become increasingly important as computer attacks increase in number, publicity and dama...

Background: Musculoskeletal disorders (MSDs) are among the most prevalent pains which could be ignited via material handling. Backpack wearers are among those who may carry heavy loads. Since MSDs mainly originate in school-aged children, students (as the largest group of backpack wearers) are considered more important. The purpose of this study is to design a backpack based on minimization of ...

o bjectives: headgears are among the effective orthodontic appliances to achieve treatment goals. unilateral molar distal movement is sometimes needed during an orthodontic treat- ment, which can be achieved by an asymmetric headgear. different unilateral headgears have been introduced. the main goal of this study was to analyze the force system of uni- lateral expanded outer bow asymmetric hea...

In 2001, following the development of International Standards in basic medical education, WFME appointed an international Task Force for development of International Guidelines for Postgraduate Specialist Training. Reports of this Task Force were published in September 2001. These Guidelines has been structured in 9 areas and 37 sub-areas. The areas of these guidelines are mission & outcomes, t...
