Determination of Rectification Corrections for Semi Gantry Crane Rail Axes in the Local 3D Coordinate System

Abstract

Electronic tacheometers are currently the standard instruments used in geodetic work, including also geodetic engineering measurements. The main advantage connected with this equipment is among others high accuracy of the measurement and thus high accuracy of the final determinations represented for example by the points’ coordinates. One of many applications of the tacheometers is the measurement of crane rail axes. This measurement is based on polar method and it allows to get the spatial coordinates of points in 3D local system. The standard technology of measurement of crane rail axes and development of its calculations’ results is well-known and widely presented in the subject literature. At the same time new methods of observations results evaluation are developing.

Some new proposals for the development of measurement results were already presented in (Kamiński, 2013).

This paper is a generalisation of the paper quoted above. The authors developed the concept which was presented there by a proposal for determining rectification corrections for semi gantry crane rail axes. To carried out the task, the parametric method with conditions on parameters was used. Moreover the practical tests on simulated measurement results were conducted. The results obtained from alignment confirmed the theoretical assumptions.

Despite the fact that analyses were carried out only on the simulated data, it is already possible to say that presented method for determination of rectification corrections for crane rail axes can be used for development of the observations from real measurement.

Rectifying memristor bridge circuit realized with human skin

License. Measurements were done on 28 test subjects with constant amplitude (+1 V and – 1 V) sinusoidal voltages of different very low frequencies that were applied via surface electrodes (see Fig. 1c .) The currents recorded from some subjects were (more or less) half-wave rectified and for some other subjects the obtained currents had double the frequency as the applied voltages. A parameter that reflects the amount of rectification is introduced and used for quantitative analysis. The recordings here are affected by the applied voltage itself and can

Rectification of invalidly published new names for plants from the late Eocene of North Bohemia

Abstract

Valid publication of new names of fossil plant taxa published since 1 January 1996 requires a diagnosis or description in English, besides other requirements included in the International Code of Nomenclature for algae, fungi, and plants (Melbourne Code) adopted by the Eighteenth International Botanical Congress, Melbourne, Australia, July 2011 (McNeill et al. 2012). In order to validate names published from the late Eocene flora of the Staré Sedlo Formation, North Bohemia, diagnosed only in German (Knobloch et al. 1996), English translations are provided, including references to the type material and further relevant information.

Two New Fissidens Species (Fissidentaceae) from Tropical Eastern Africa and Fissidens Bessouensis Corb., a Remarkable Species with Fimbriate Leaves and Multicellular Spores

Abstract

Fissidens acrophilus Bruggeman-Nannenga, sp. nov. (subgenus Fissidens) from Kenya and Uganda and F. obscurifrons Bruggeman-Nannenga, sp. nov. (subgenus Fissidens?) from Tanzania are newly described and figured. F. obscurifrons is compared to the little known Madeiran F. nobreganus Luisier & P. de la Varde. A revision of F. bessouensis Corb. (subgenus Octodiceras) with description, diagnosis and figures and a discussion including adaptations to an aquatic habitat is presented. Multicellular spores and fimbriate leaf margins are reported in the Fissidentaceae for the first time. Rectification: F. angustelimbatus Mitt. is eliminated from the African flora.

Electrical properties of hybrid planar diode based on palladium phthalocyanine and titanium dioxide

Abstract

This work presents experimental studies of a planar diode made of the layers of indium tin oxide, titanium dioxide, palladium phthalocyanine and gold. The current rectification ratio was 105 at 1.5 V. The analysis of the electrical properties of the system was based on small signal complex capacitance spectra measured in the frequency range of 25 Hz — 1 MHz at different values of bias. No depletion region at the TiO2/PdPc interface was observed. Forward bias specifically affected both parts of the complex capacitance and the observed effect probably resulted from the rearrangement of charge carriers injected into the organic layer.

Explaining Events in Narratives: The Impact of Scaffolding in 4 To 12 Year Old Children

Explaining Events in Narratives: The Impact of Scaffolding in 4 To 12 Year Old Children

The focus of this article is the manner in which 4 to 12 year old children deal with the "evaluative" component of narratives (Labov & Waletsky, 1967). After spontaneously telling their first version of a story of a misunderstanding between two characters, constructed on the basis of a sequence of five images, children participated in a scaffolding procedure during which they were questioned about the reasons for the events. After this non-intrusive, Piagetian-styled clinical interview, children were asked to recount the story a second time. For children's first narratives, our study confirms earlier results by showing that, before 8-9 years, children rarely mention the epistemic states of the characters. The false belief of one of the characters and its rectification are rarely mentioned before 10-11 years and even at that age by few children. Presenting a story based on a misunderstanding does not facilitate this kind of narration. However, in the narrative produced after scaffolding, 6-7 year old children increase considerably their references to the characters' internal states, and from 8-9 years, the expression of false belief and of its rectification. These results call for multiple evaluations in order to best grasp children's narrative competence.

Analysis of C3 fraction splitting system performance by mathematical modeling in MATLAB environment

Abstract

Propane-propylene mixture splitting by industrial conventional rectification incorporating a heat pump for energy intensity decrease was modeled in the Matlab environment. The constructed model was verified by comparing its results with operational data of a real C3 fraction splitting unit. As documented, increased product quality can be obtained at zero additional costs due to specific features of the system design. Process capacity and product purity limitations have to be considered in future C3 fraction production increase plans. Further compressor and its driving unit design features have to be incorporated in the calculation model to reliably assess the C3 fraction processing costs and provide a reliable tool for process operation optimization.
