This paper describes the rainfall data generation processes, which were used to simplify the recharge model developed by Khazai and Spink. The principles of techniques used for single and two sites generation are discussed. The application of the techniques for extending the rainfall records at the existing stations and increasing arbitrarily the numbers of rain gauges within the catchment are ...

We extend a previous Landau-gauge study of subtractive renormalization of the fermion propagator Dyson-Schwinger equation (DSE) in strong-coupling, quenched QED4 to arbitrary covariant gauges. We use the fermion-photon proper vertex proposed by Curtis and Pennington with an additional correction term included to compensate for the small gauge-dependence induced by the ultraviolet regulator. We ...

A class of covariant gauges allowing one to interpolate between the Landau, the maximal Abelian, the linear covariant and the Curci-Ferrari gauges is discussed. Multiplicative renormalizability is proven to all orders by means of algebraic renormalization. All one-loop anomalous dimensions of the fields and gauge parameters are explicitly evaluated in the MS scheme. LTH–652 Research Assistant o...

This paper suggests a simple yet efficient experimental method to record the displacement of the shaft in a revolute joint with clearance. Two light and compliant cantilevers have been mounted on the rocker, each being instrumented with two strain gauges which can measure bending. These cantilevers are mounted in an orthogonal fashion, near the axis of the revolute joint, each touching the shaf...

This paper elaborates on the rationale behind the proposed standard limits for the accuracy of rainfall intensity measurements obtained from tipping-bucket and other types of rain gauges. Indeed, based on experimental results obtained in the course of international instrument Intercomparison initiatives and specific laboratory tests, it is shown here that the accuracy of operational rain gauges...

A single-parameter family of covariant gauge fixing conditions in bosonic string field theory is proposed. It is a natural string field counterpart of the covariant gauge in the conventional gauge theory, which includes the Landau gauge as well as the Feynman (Siegel) gauge as special cases. The action in the Landau gauge is largely simplified in such a way that numerous component fields have n...

Nonlinearity and hysteresis effects of electrostatically activated, voltage driven resonant microbridges have been studied theoretically and experimentally. It is shown, that, in order to avoid vibration instability and hysteresis to occur, the choices of the ax . and d.c. driving voltages and of the quality factor of a resonator, with a given geometry and choice of materials, are limited by a ...

Measuring a bone’s response to impact has traditionally been done using strain gauges that are attached directly to the bone. However, in addition to being invasive (in vivo), strain gauges are expensive, are generally used only once, and can be difficult to assemble and attach to the specimens being tested. While accelerometers are an attractive tool to overcome these limitations [1], little d...

Although human dental anatomy is taught in university curricula, clinicians often witness restorations that are not proportional to one another. Dental restorations should also be proportional to periodontal supporting tissues as an essential aspect of dental anatomy. Measurements can be performed directly on a patient's teeth with aesthetic gauges used to confirm the correct position of the su...
