Objective: It is essential to have a suitable instrument for accurate assessments of pain and disability outcomes during interventions and to guide hand surgery and rehabilitation programs in distal radius or scaphoid fracture. This study was designed to evaluate the psychometric features of the Patient-rated Wrist Evaluation (PRWE) questionnaire in Iranian persons with a history of scaphoid an...

In today’s digital world, many established analog techniques are being replaced by modern digital alternatives. Digital modulation is now commonplace, particularly in mobile communications, but traditional analog amplitude and frequency modulation are still in widespread use. Laboratories performing RF calibration report that analog modulation meters and analyzers are a part of their workload t...

Why mix at all? Generally, a design uses analog components for two reasons: to interface digital processing with applicationspecific environments and to accelerate processing in high-performance systems. Many applications include interactions among electronics and various sensors and actuators: such interactions imply analog signals. To further complicate the task of mixed-signal design, many o...

Reliability of systems used in space, avionic and biomedical applications is highly critical. Such systems consist of an analog front-end to collect data, an Analog-to-Digital Converter (ADC) to convert the collected data to digital form and a digital unit to process it. Though considerable amount of research has been performed to increase the reliability of digital blocks, the same can not be ...

This report describes an effort to develop a technique for measuring the amount of fault detection coverage that an analog test pattern has for a particular analog device. The technique is based on a software tool which statistically analyzes data from a circuit simulator. One example of a fault simulation experiment is presented, and some of the results are discussed. Finally, some ideas for f...
