Kepler's orbital motion examined in comparison with the methods of mechanics developed by Stanescu and Tabacu
No full textA new method developed by Stanescu and Tabacu to study the mechanics of a particle moving along a definite curve is compared with the well-known approach applied in calculating the Kepler's orbital motion. A particular effect of the rate of change of the kinetic energy of a body with respect to the change of a parameter defining the body position on the orbit is examined as an example. A comparison of the two methods shows only a slight numerical difference between the results of the Stanescu-Tabacu method and the traditional formalism. The components of the body acceleration are calculated along the orbit as an application of the new approach

Dynamic performance of a speed sensorless induction motor drive with flux weakening operation
No full textThe paper 1 is concerned with the operation in dynamic regime of an induction motor drive operated into deep flux weakening operation. Based on the induction motor's mathematic model, an algorithm for sensorless direct flux vector control (SDFVC) was implemented. The control schematic for SDFVC is described. The stator flux amplitude is controlled by the d s axis voltage component, while the load angle (and thus the torque) is regulated by the q s -axis voltage component. The proposed algorithm is suitable for low cost induction motor drives where accuracy in the speed estimation is not mandatory and is based on a closed-loop stator flux observer. The vector control block is realised with two PI regulators, the output of this regulators being the reference voltages in the stator coordinates oriented along the stator flux. The authors studied the behavior of a drive system in the field weakening zone, in order to get a maximum torque considering the limitations imposed to currents and voltages. The system was also tested in transient regimes of acceleration and deceleration, the stationary regime being studied too. The experimental data gathered during the accomplishing of the drive system tests when the control algorithm was employed are presented and discussed in the end. The tested three phase induction motor has a power of 4 kW
Predation of Dermatonotus muelleri (Boettger 1885) by Lepidobatrachus llanensis Reig and Cei 1963
No full textOn 7 December 2013, we performed an intensive night survey between the localities Fuerte Esperanza and Misión Nueva Pompeya, in the Chaco Province, northern Argentina. The night was preceded by a heavy storm, creating a multitude of temporary ponds. The environmental conditions triggered the explosive reproduction in D. muelleri: vocalizing adult males were heard in addition to observations of pairs in amplexus inside water bodies and the presence of females on land which were headed to the breeding ponds. At 00.48 hours, we witnessed an adult D. muelleri being preyed upon by an adult Lepidobatrachus llanensis Reig and Cei 1963 on the side of a dirt-road segment (Ruta Provincial no. 61) (25°0?8.52?S, 61°30?50.25?W).Fil: Stanescu, Florina.

Author's personal copy Forecasting VaR using analytic higher moments for GARCH processes

It is widely accepted that some of the most accurate Value-at-Risk (VaR) estimates are based on an appropriately specified GARCH process. But when the forecast horizon is greater than the frequency of the GARCH model, such predictions have typically required time-consuming simulations of the aggregated returns distributions. This paper shows that fast, quasi-analytic GARCH VaR calculations can be based on new formulae for the first four moments of aggregated GARCH returns. Our extensive empirical study compares the CornishFisher expansion with the Johnson SU distribution for fitting distributions to analytic moments of normal and Student t, symmetric and asymmetric (GJR) GARCH processes to returns data on different financial assets, for the purpose of deriving accurate GARCH VaR forecasts over multiple horizons and significance levels

E-mail: [email protected] Double or multiple antigen labeling in IHC classically relies on the existence of primary antibodies raised in different species or of different IgG isotypes to ensure the specific labeling with the secondary detection systems. However, suitable pairs of primary antibodies are not always available or the best choice (e.g., as diagnostic tools). During the last few years, several methods have been proposed to overcome this, but none of them offers the flexibility needed for reliable double or multiple enzymatic or fluorescent IHC. We present here a procedure that elutes the antibodies after a first round of immunolabeling, which, in combination with precipitation-based detection systems, allows multiple IHC rounds even for primary antibodies raised in the same species and IgG isotype. Compared with other proposed methods, this procedure ensures a reliable enzymatic or fluorescent staining without cross-reactivity and without loss of tissue antigenicity, thus offering a flexible tool for colocalization studies and pathological diagnosis.

Structural and electronic properties of thin Ni layers on Cu(1 1 1) as investigated by ARPES, STM and GIXD
No full textThe growth and the crystalline and electronic structure of Ni deposited on single crystalline Cu(1 1 1) were studied by scanning tunnelling microscopy (STM), grazing incidence X-ray diffraction (GIXD) and angle-resolved photoemission spectroscopy (ARPES). In the early stages of growth monoatomic-high flat Ni islands, partially covered by Cu migrating from the surface, are observed. Starting from a pseudomorphic epitaxial relationship the in-plane lattice parameter progressively relaxes with increasing coverage. For a 20 monolayer (ML) thick deposit the in-plane lattice parameter is still found halfway between the bulk Ni and Cu lattice parameters. ARPES data also rule out the layer-by-layer growth and provide the values of the Ni exchange splitting
