Abstract:

The low frequency phase characteristics of microphones in a monitoring system are crucial for characterizing large-scale natural and artificial activities—e.g., earthquakes, nuclear explosions, or rocket launchings. At present, microphones are simultaneously calibrated using in-situ or calibrator methods to get their phase consistency. However, the essential primary calibration, which traces their phase sensitivity to basic physical quantities, is grossly overlooked. Recently, we speculated that the microphone phase sensitivity is acoustically controlled by the pressure leakage and heat conduc

An experimental campaign based on multiaxial tests is carried out to characterize the ductile behavior of 17-4PH steel and a Ti6Al4V titanium alloy, and to calibrate numerical ductile damage models, accordingly. This study aimed to identify a minimal set of four specimen types to ensure the robust tuning of the damage models, using only a conventional uniaxial machine for testing. Two different shear–tension candidate geometries are identified, modified, and used together with cylindrical and notched bar specimens to evaluate material plastic strain at fracture under several stress states, cha

Abstract:

Purpose 2D laser rangefinders (LRFs) are commonly used sensors in the field of robotics, as they provide accurate range measurements with high angular resolution. These sensors can be coupled with mechanical units which, by granting an additional degree of freedom to the movement of the LRF, enable the 3D perception of a scene. To be successful, this reconstruction procedure requires to evaluate with high accuracy the extrinsic transformation between the LRF and the motorized system. Design/methodology/approach In this work, a calibration procedure is proposed to evaluate this transformation.

As a result, a 1 min time resolution database of geometrically and radiometrically calibrated HDR images has been created and has been available since February 2020, with daily updates.

Abstract. The scattering parameters of embedded devices can be measured by means of contactless vector network analysis. To achieve accurate measurement results, the contactless measurement setup has to be calibrated. However, if the substrate material or the planar transmission lines on the substrate changes, a new calibration is necessary. In this paper a method will be examined, which reduces the number of calibration cycles by using a database. Analytical results show that by using this database method, errors occur which depend on the coupling coefficients and on the load impedances of th

Abstract:

Abstract The neutral gases released by the intense volcanic activity of the Jupiter moon Io, once ionized by the Jupiter magnetic environment, give rise to a toroidal plasma distribution known as the Io plasma torus (IPT). Radio signals passing through charged-particle environments such as the IPT are heavily perturbed proportionally to the rate of change of the charged-particle distribution along the path of the radio wave. If not properly calibrated, the IPT may induce significant perturbation on the radiometric tracking link to Earth. The radio tracking signal is the main observable for the

The influence of the probe size and geometry on the quality of fast-response measurements in turbomachines has been experimentally investigated.

For dynamic calibrations in time-variant flows model experiments in water (0.025 < k < 0.4, reduced frequency) were performed. Aerodynamic characteristics were determined for a great number of probe geometries, such as circular cylinders and wedge-type probes with varied apex angles,

Abstract:

Abstract The theory of calibrated geometry was invented by Harvey and Lawson in their seminal paper [151], which is still an excellent reference. It concerns calibrated submanifolds, a special kind of minimal submanifold of a Riemannian manifold M , which are defined using a closed form on M called a calibration. It is closely connected with the theory of Riemannian holonomy groups because Riemannian manifolds with reduced holonomy usually come equipped with one or more natural calibrations.

Abstract:

Abstract Drinking and talking are physiologically complementary activities, that, though impossible to do simultaneously, are often brought into closer or looser relation in rituals. One place to look to explore the ritualized linkage of drinking and speaking is to explore what kinds of metricalized calibrations exist between the obviously semiotic order of speaking and the material order of drinks. When drinking is embedded in a ritual action, accompanied by a performative utterance such as a toast, drinking is closely calibrated to talk and foregrounded as being in itself a performative act

Abstract:

Abstract In Chapter 4 we defined calibrations and calibrated submanifolds. We now apply these ideas to manifolds with exceptional holonomy. There are two types of calibrated submanifolds in 7-manifolds with holonomy G 2, called associative 3-folds and coassociative 4-folds, and one in 8-manifolds with holonomy Spin(7), called Cayley 4-folds. Coassociative 4-folds can be defined in terms of the vanishing of a closed form. This implies that they behave rather like special Lagrangian submanifolds in Chapter 8, so that moduli spaces of compact coassociative 4-folds are smooth, for instance.

To maintain measurement accuracy, stationary volume provers must be re-proved periodically. The most direct method of determining a provers volume is through a process known as water drawing where water is circulated through the prover and swept into certified measurement volumes.

However, proving with water requires that the prover be first cleaned of any hydrocarbon product that may alter the working volume of the prover and create waste products that must be handled properly.
