Reducing instrumentation points in Larva
When dealing with the correctness assurance of huge and complex systems, runtime verification is becoming an increasingly popular technique. The Larva tool was built to automatically generate runtime verification monitors that would help to validate the behavior of Java programs at runtime. The …

Tractive Performance From Axle Instrumentation
… be measured in the axles driving the wheels. An instrumentation system was developed to measure the bending forces in an unreduced section of axle. Two four-gage, constant current, semiconductor strain gage bridge circuits were developed to measure the strains associated with the bending forces. …

Development of instrumentation for acoustic monitoring
This thesis describes a source/sink flow acoustic wave sensor for the identification of leaks in gas pipelines. One of the many type of signals associated with the high velocity gas flowing out of a hole in the pipeline is the ramp or step pressure drop.;A large 3-inch diameter diaphragm was …

Field instrumentation for vocalizing avian survey
We present automated instruments to facilitate the monitoring of vocalizing species in their environment with minimal disruption. These devices offer recording and acoustic localization of bird calls and relay data via the GSM cellular network to remote servers. Further, the system may be augmented …

On the instrumentation of the Omniscope
An emergent technique known as 21-cm tomography has the potential to become the most sensitive tool we have for probing the early universe. It is expected to shed light on some of the most pressing questions in modern physics-such as the nature of dark matter. However, there are significant …

A nano-stepping robotic instrumentation platform
The development of an Autonomous Nano-stepping Tool (ANT) system is presented. Each ANT is a small, tripodal, robotic instrument capable of untethered precision motion within a quasi-three-dimensional workspace of arbitrary size. The project aimed to address limitations of conventional benchtop …

Compacted Snow Testing Methodology and Instrumentation
Snow is a complex material that is difficult to characterize especially due to its high compressibility and temperature-sensitive nonlinear viscoelasticity. Snow mechanics has been intensively investigated by avalanche and army researchers for decades. However, fewer research studies have been …

SAMPLE INTRODUCTION AND INSTRUMENTATION IN PLASMA SPECTROMETRY
Plasma spectrometry is now a widely accepted technique for the determination of the elemental composition of a wide range of sample types. The successful introduction of volatile organic solvents has however been limited, due to the resulting high solvent loading of the plasma and subsequent plasma …

Instrumentation in the Works of Witold Lutoslawski
The music of Witold Lutoslawski displays instrumentational traits which may be used, in conjunction with melodic, rhythmic, and harmonic tendencies, to define his compositional style. The use of instrumental color is examined in all major works up to and including Chain 3 (1986), with an emphasis …
