Geocentric Coordinates

The article describes one of the methods for determining the geodetic height by using the satellite as a moving target points. It is shown that the chronology of the development of the satellite method for determining the geodetic height of the iterative calculation method for the open-closed formulas for the dependence of the geodetic latitude and, finally, to closed formulas determining the geodetic height in function exclusively from geocentric coordinates. This article describes the geometrical (volumetric and flat) models to perform the derivation of the formulas for determining the geodetic height as a function of the geocentric coordinates of the point. Two variants of the formulas obtained by the authors to determine the geodetic height.

Academic Debate

The current academic debate on the sharing economy (SE) seems to embrace three main discussions: its definition, its effects, and the role of regulation. A neglected topic here seems to be analyzing the specific implications of the changing nature of these firms boosted by private equity and venture capital. As the author points out, we need to analyze not only the impact of a changing business model but, specifically, how stakeholders, cities, and regulators should approach this moving target now called SE. In the following sections the author departs from a traditional definition of the sharing economy to start building the case for treating the SE at large as an epiphenomenon of the platform economy, and as a temporary condition based on a moveable business model. The chapter closes by introducing the regulatory hurdles that come associated with the previous and mapping out its different futures.

AbstractThis response to Pérez-Cañado’s (2017) disappointing defence of CLIL interests insists on the need for a clear definition of CLIL not only so that it can be characterised for comparative purposes, but also so that the fundamentals underlying it can be scrutinised, instead of the continued hedging of bets on a moving target, justified for its contextual flexibility. As an example, whether CLIL classes are accompanied by FL classes on the curriculum or not is not a minor issue, both practically and theoretically. In addition other questions are reconsidered such as the communicative nature of CLIL, especially when it comes to whether the content is likely to be more motivating, and the supposed egalitarianism of CLIL initiatives. Finally, two research issues are discussed. Firstly, an example demonstrates how it is perfectly legitimate to critique empirical CLIL research which argues apparently beneficial results from a ‘due to’ stance by countering it with ‘despite’ arguments, while leaving much of the flawed CLIL research aside. Secondly, there is a reiterated demand that disinterested research at a curricular level confront outcomes in both the FLs and the content covered in CLIL programmes for all the state-school students affected both directly or indirectly, and in comparable terms.

The inadequacy of the existing ASTM E950 method for definition of the bias of an inertial profiler in the measurement of a pavement profile is analyzed. An improved bias calculation method is proposed. An analysis of the profile measurements and international roughness indexes (IRIs) of four pavement locations was conducted, and the results show that there is no statistical correlation between the profile biases and IRI bias. This analysis demonstrates that a profiler classified as having high accuracy in measuring profiles by ASTM E950 or other proposed bias criteria does not necessarily provide an accurate measurement of IRI. Therefore, it is recommended that the accuracy of a profiler in the measurement of IRI be evaluated independently when IRI, instead of profile, is used for a smoothness specification or other purposes. A criterion to evaluate profilers’ accuracy to measure IRI is developed based on the concept of probability.

This paper includes a definition of a new and original concept in the photovoltaic field,RMS currentof a photovoltaic generator for grid-connected systems. TheRMS currentis very useful for calculating energy losses in cables used in a PV generator. As well, acurrent factorhas been defined in order to simplifyRMS currentcalculation. This factor provides an immediate (quick and easy) calculation method for theRMS currentthat does not depend on the case particular conditions (orientation, location, etc.).RMS currentandcurrent factorvalues have been calculated for different locations and modules.
