چکیده
Abstract. Quantum gravimeters are a promising new development allowing for continuous absolute gravity monitoring while remaining user-friendly and transportable. In this study, we present experiments carried out to assess the capacity of AQG#B01 in view future deployment as field gravimeter hydrogeophysical applications. The is version follow-up AQG#A01 portable quantum developed by French sensor company Muquans. We instrument's performance terms stability (absence instrumental drift) sensitivity relation other gravimeters. No significant drift was observed over several weeks measurement. discuss observations concerning accuracy comparison with state-of-the-art (Micro-g-LaCoste, FG5#228). report repeatability be better than 50 nm s?2. This study furthermore investigates whether changes instrument tilt external temperature combination both, which likely occur during campaigns, influence measurement gravitational attraction. repeatedly tested temperatures between 20 30 ?C did not find any effect. As an example geophysical signal, 100 s?2 change detected after rainfall event at Larzac geodetic observatory (southern France). data agreed measured superconducting relative (GWR, iGrav#002) expected simulated infinite Bouguer slab approximation. 2 stable operation under semi-terrain conditions garage without temperature-control. close operational recommendations potential users specific possible While claiming completeness, nevertheless first characterization users. Selected criteria assessment its suitability applications have been investigated complemented discussion further necessary experiments.

Field Tests of a Portable MEMS Gravimeter
Gravimeters are used to measure density anomalies under the ground. They are applied in many different fields from volcanology to oil and gas exploration, but present commercial systems are costly and massive. A new type of gravity sensor has been developed that utilises the same fabrication methods as those used to make mobile phone accelerometers. In this study, we describe the first results ...

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولAn absolute formalism for quantum mechanics
The wave function of quantum mechanics is not a boost invariant and gauge invariant quantity. Correspondingly, reference frame dependence and gauge dependence is inherited to most of the elements of the usual formulation of quantum mechanics (including operators, states and events). If a frame dependent and gauge dependent formalism is called, in short, a relative formalism, then the aim of the...
