Chemical Sensors for Portable, Handheld Field Instruments
A review of three commonly used classes of chemical sensor technologies as applicable to implementation in portable, handheld field instruments is presented. Solid-state gas and chemical sensors have long been heralded as the solution to a wide variety of portable chemical sensing system applications. However, advances in optical sensing technology have reduced the size of supporting infrastruc...

Applying ultrasonic echolocation-based measurement method to increase the accuracy of leveling instruments
Current mechanical, laser and electronic leveling instruments are sometimes not accurate enough to be used for determining either vertical or horizontal level for level-critical applications. By using an ultrasonic echolocation-based distance meter it is possible to design very accurate leveling instruments for a wide range of applications. This article overviews the accuracy of current levelin...
متن کاملLuminosity leveling with angle
The very high luminosity foreseen for the LHC luminosity upgrade entails in all cases a significant luminosity decrease during a few hours run. We present in this note a new method of luminosity leveling, based on the on-line adjustment of the crossing angle, while keeping the optics unchanged. It is implemented using the D0 dipole of a possible Early Separation Scheme and an orbit corrector. T...
متن کاملCyclic Leveling of Directed Graphs
The Sugiyama framework is the most commonly used concept for visualizing directed graphs. It draws them in a hierarchical way and operates in four phases: cycle removal, leveling, crossing reduction, and coordinate assignment. However, there are situations where cycles must be displayed as such, e. g., distinguished cycles in the biosciences and processes that repeat in a daily or weekly turn. ...
