Program instrumentation has a wide variety of useful applications, but tool writers must overcome the challenge of substantial overheads caused by introducing additional code and data into a program. This paper observes that instrumentation usually operates on many discrete, independent data structures, which we callmetadata parallelism. We proposes to exploit this phenomenon to reduce the over...

the vestibular system is important for the development of normal movement reactions, motion tolerance, and motor control for postural alignment, balance, and vision. a vestibular system that is damaged by disease or injury in childhood can have a major impact on a child's development. in addition, the emergence of vestibular lesions may also lead to cognitive deficits, including attention defic...

CONTEXT One of the goals of endodontic therapy is the shaping and cleaning of the root canal system. In recent years, there has been multiple systems instrumentation, and changes in their dynamics are central to maintain the original shape of the canal after preparation. AIMS The aim of this study was to evaluate centering and transportation in curved root canals after using ProTaper(®) and M...

One of the fundamental aspects of ubiquitous computing is the instrumentation of the real world by smart devices. This instrumentation constitutes an opportunity to rethink the interactions between human beings and their environment on the one hand, and between the components of this environment on the other. In this paper we discuss what this understanding of ubiquitous computing can bring to ...

According to the requirements of nuclear safety regulations, power plants must be equipped with seismic instrumentation systems, which are mainly used for monitoring alarm and automatic shutdown during an earthquake. Both second third generation NPPs adopt Peak Ground Acceleration (PGA). However, among acceleration characteristics, isolated prominent single high frequency peaks have no decisive...

In this paper, we propose that measurements and instrumentation are essential to maintaining the stability and integrity of any system. Any general system has a healthy and acceptable range of parameter values. In scientific, medical or engineering environments, such parameter values need consistency; validation and affirmation ensure that the scientific, medical and engineering processes withi...
