3D digital holographic polarimetry

3D digital holographic polarimetry

Lap Lambert Academic Publishing

The experimental validation of methods for digital holographic 3D layer-by-layer reconstruction of complex amplitude distributions in different phase planes of diffuse biological tissues histological sections microscopic images with subsequent reconstruction of azimuth and ellipticity polarization maps is presented. Polarization dependencies of the integral and layer-by-layer vector structure of the laser object field azimuth and ellipticity distributions in two types of biological layers samples - fibrous myocardium and parenchymal liver - have been investigated. Scenarios and dynamics of changes in the values of statistical moments of the 1st to 4th orders, which characterize the integral and layer-by-layer polarization maps of diffuse biological tissues histological sections microscopic images with different morphological structures, have been determined. Criteria for selecting the polarization components of the object field that are formed by acts of scattering of different multiplicities have been identified.

Methods of sociological study of adolescents

Methods of sociological study of adolescents

The book deals with methods and techniques of sociological research for the study of adolescents. It describes the peculiarities of using qualitative and quantitative methods of studying adolescents, the possibilities of mutual complementation of "hard" and "soft" methods. The main problems of studying adolescents in the sociological perspective are specified. On the example of the author's empirical research experience the ways of solving these problems are revealed. The details of conducting interviews and questionnaires with adolescents are shown: the time of working with them, the peculiarities of formulations and the structure of tools. Non-standard methods for studying adolescents are proposed: projective and drawing techniques, the method of collisions. Further prospects of studying the group under study using slang and so-called "memes" in the toolkit are described.

Das Buch befasst sich mit Methoden und Techniken der soziologischen Forschung f r die Untersuchung von Jugendlichen. Es beschreibt die Besonderheiten des Einsatzes qualitativer und quantitativer Methoden bei der Untersuchung von Jugendlichen, die M glichkeiten der gegenseitigen Erg nzung von "harten" und "weichen" Methoden. Die Hauptprobleme der Untersuchung von Jugendlichen aus soziologischer Sicht werden dargelegt. Am Beispiel der Erfahrungen aus der empirischen Forschung des Autors werden die Wege zur L sung dieser Probleme aufgezeigt. Die Details der Durchf hrung von Interviews und Frageb gen mit Jugendlichen werden aufgezeigt: die Zeit der Arbeit mit ihnen, die Besonderheiten der Formulierungen und die Struktur der Instrumente. Es werden nicht standardisierte Methoden zur Untersuchung von Jugendlichen vorgeschlagen: projektive und zeichnerische Techniken, die Methode der Kollisionen. Weitere Perspektiven f r das Studium der untersuchten Gruppe unter Verwendung von Slang und so genannten "Memen" im Toolkit werden beschrieben.

A groundbreaking book that applies new geometric tools to one of the oldest problems in representation theory, expanding the field and paving the way for further progress In the 1920s, Hermann Weyl gave a complete classification of the irreducible unitary representations of a compact Lie group G. Around the same time, Fritz Peter and Weyl showed that these irreducible unitary representations are fundamental objects for harmonic analysis on G. If G is instead a noncompact Lie group, such as GL_n(R), the classification of the irreducible unitary G-representations is a much more di?cult problem, one that remains open in general. An idea, with its origins in the work of Kostant, Kirillov, and Vogan, is that the set of irreducible unitary G-representations should contain a finite set of “building blocks,” called unipotent representations, related to the set of nilpotent co-adjoint G-orbits. This book proposes a definition and theory of unipotent representations in the case of when G is a complex reductive Lie group, such as GL_n(C). This definition is based on the theory of quantizations of symplectic singularities, especially the geometry of nilpotent co-adjoint orbits and their equivariant covers. The main theorems include a geometric classification of unipotent representations, a calculation of their infinitesimal characters, and a proof of their unitarity in the case of classical groups. Although further obstacles remain, this work paves the way for a general theory of unipotent representations of reductive Lie groups, which should in turn form the basis of the classification of irreducible unitary representations.

Evolution of Motions of a Rigid Body About its Center of Mass

Evolution of Motions of a Rigid Body About its Center of Mass

Springer International Publishing AG
2017
sidottu
The book presents a unified and well-developed approach to the dynamics of angular motions of rigid bodies subjected to perturbation torques of different physical nature. It contains both the basic foundations of the rigid body dynamics and of the asymptotic method of averaging. The rigorous approach based on the averaging procedure is applicable to bodies with arbitrary ellipsoids of inertia. Action of various perturbation torques, both external (gravitational, aerodynamical, solar pressure) and internal (due to viscous fluid in tanks, elastic and visco-elastic properties of a body) is considered in detail. The book can be used by researchers, engineers and students working in attitude dynamics of spacecraft.

Die Zahl der auf dem pharmazeutischen Markt eingef hrten Arzneimittel nimmt jedes Jahr zu. Bei diesen Arzneimitteln kann es sich entweder um neue Wirkstoffe oder um eine teilweise strukturelle Ver nderung bestehender Wirkstoffe handeln. Das Ziel jeder analytischen Messung ist es, konsistente, zuverl ssige und genaue Daten zu erhalten. Heutzutage wird die pharmazeutische Analyse von physikalisch-chemischen Analysemethoden beherrscht, von denen die zuverl ssigsten die chromatographischen Methoden sind. Chromatographische Methoden erm glichen die qualitative und quantitative Bestimmung von Wirkstoffen.
