Generalized Camassa-Holm Equations: Symmetry, Conservation Laws and Regular Pulse and Front Solutions

2021

In this paper, we consider a member of an integrable family of generalized Camassa–Holm (GCH) equations. We make an analysis of the point Lie symmetries of these equations by using the Lie method of infinitesimals. We derive nonclassical symmetries and we find new symmetries via the nonclassical method, which cannot be obtained by Lie symmetry method. We employ the multiplier method to construct conservation laws for this family of GCH equations. Using the conservation laws of the underlying equation, double reduction is also constructed. Finally, we investigate traveling waves of the GCH equations. We derive convergent series solutions both for the homoclinic and heteroclinic orbits of the…

Depth Enhancement by Fusion for Passive and Active Sensing

2012

This paper presents a general refinement procedure that enhances any given depth map obtained by passive or active sensing. Given a depth map, either estimated by triangulation methods or directly provided by the sensing system, and its corresponding 2-D image, we correct the depth values by separately treating regions with undesired effects such as empty holes, texture copying or edge blurring due to homogeneous regions, occlusions, and shadowing. In this work, we use recent depth enhancement filters intended for Time-of-Flight cameras, and adapt them to alternative depth sensing modalities, both active using an RGB-D camera and passive using a dense stereo camera. To that end, we propose …

Clasificación molecular de los componentes de los aceites de Eucalyptus camaldulensis y de Mentha pulegium

2020

Eucalyptus and Mentha remain flavours in agro-food manufacturing. Oils and components present antifungal potency vs . decay of fruits; E. camaldulensis is led by 1,8-cineole and a -pinene, unlike M. pulegium , which is led by pulegone. The antifungal activity of M. pulegium is three times more frequent than that of E. camaldulensis . The phytochemicals present synergy. Categorization is recommended on the basis of information entropy . The quantity of C-C double bonds, O-atoms and cycles cluster structures. The procedure undergoes a combinatorial upsurge. Nevertheless, following equipartition conjecture, one gets a criterion for selection. Entropy allows clustering phytochemicals according …

The Wide Field Imager instrument for Athena

2017

ESA's next large X-ray mission ATHENA is designed to address the Cosmic Vision science theme 'The Hot and Energetic Universe'. It will provide answers to the two key astrophysical questions how does ordinary matter assemble into the large-scale structures we see today and how do black holes grow and shape the Universe. The ATHENA spacecraft will be equipped with two focal plane cameras, a Wide Field Imager (WFI) and an X-ray Integral Field Unit (X-IFU). The WFI instrument is optimized for state-of-The-Art resolution spectroscopy over a large field of view of 40 amin x 40 amin and high count rates up to and beyond 1 Crab source intensity. The cryogenic X-IFU camera is designed for high-spect…

Israel State, Genocide and Thana-Capitalism

2019

The term “genocide” was originally coined by Lemkin just after the horrendous crimes committed against innocent civilians in Nazi Germany. At that moment, the SS officials disposed of a systemic rationalized system of death which was oriented to domesticate and eradicate the “inferior” or the undesired “Other”. The concentration camps were space of torture, violence, death and mourning that marked the state of Israel forever. Today things have changed a lot, and the state of Israel is accused of violating the human rights in Palestine. While we review the discussion of senior lecturers such as Slavoj Žižek, Richard Bernstein, Norman Finkelstein and Yakov Rabkin, we reconstruct the philosoph…

Water quality modelling for ephemeral rivers: Model development and parameter assessment

2010

Summary River water quality models can be valuable tools for the assessment and management of receiving water body quality. However, such water quality models require accurate model calibration in order to specify model parameters. Reliable model calibration requires an extensive array of water quality data that are generally rare and resource-intensive, both economically and in terms of human resources, to collect. In the case of small rivers, such data are scarce due to the fact that these rivers are generally considered too insignificant, from a practical and economic viewpoint, to justify the investment of such considerable time and resources. As a consequence, the literature contains v…

Kawalerzysta, dowódca i wykładowca - szkic do biografii gen. bryg. Konstantego Druckiego-Lubeckiego (1893-1940)

2018

Celem przeprowadzonych badań było opracowanie rozszerzonego szkicu biograficznego księcia gen. bryg. Konstantego Druckiego-Lubeckiego. Dzięki zebranym dokumentom i materiałom ustalono najważniejsze fakty z życia generała, dotyczące jego pochodzenia, nauki w Cesarskim Aleksandrowskim Liceum (Lycee Imperial Alexandre) w Petersburgu, udziału w walkach o niepodległość Polski oraz kariery w kawalerii i szkolnictwie wojskowym II RP. Udostępnione przez bliskich księcia materiały, skonfrontowane ze źródłami urzędowymi i dostępnymi publikacjami, pozwoliły także na ustalenie dodatkowych okoliczności związanych z jego śmiercią z rąk NKWD w 1940 roku. Dokumenty te umożliwiły rekonstrukcję podejmowanych…

Quantitative colorimetric-imaging analysis of nickel in iron meteorites.

2011

A quantitative analytical imaging approach for determining the nickel content of metallic meteorites is proposed. The approach uses a digital image of a series of standard solutions of the nickel-dimethylglyoxime coloured chelate and a meteorite sample solution subjected to the same treatment as the nickel standards for quantitation. The image is processed with suitable software to assign a colour-dependent numerical value (analytical signal) to each standard. Such a value is directly proportional to the analyte concentration, which facilitates construction of a calibration graph where the value for the unknown sample can be interpolated to calculate the nickel content of the meteorite. The…

New Cost Effective Titanium Based Protective and Decorative Coatings by Ion Plating Plasma Assisted IPPA

2009

The activity aiming to replace galvanic treatments by vacuum processes is based on the effort to reduce the production costs and to set-up new decorative effects impossible to be galvanically realised because the use of dielectric materials. This work describes cost effective metal-oxide and oxide-metal-oxide decorative coatings based on the use of titanium as basic material deposited by Ion Plating Plasma Assisted from Reactive Magnetron Sputtering source. A new multilayer protective and decorative structure, based on the use of titanium and titanium oxides is also presented. The protective effect against aggressive environment is obtained by alternating layers of metal and metal-oxide mix…
