description: We obtain several results about representations of rational Cherednik algebras, and discuss their applications. Our first result is the Cohen-Macaulayness property (as modules over the polynomial ring) of Cherednik algebra modules with minimal support. Our second result is an explicit formula for the character of an irreducible minimal support module in type A_{n-1} for c=m/n, and an expression of its quasispherical part (i.e., the isotypic part of "hooks") in terms of the HOMFLY polynomial of a torus knot colored by a Young diagram. We use this formula and the work of Calaque, Enriquez and Etingof to give explicit formulas for the characters of the irreducible equivariant D-modules on the nilpotent cone for SL_m. Our third result is the construction of the Koszul-BGG complex for the rational Cherednik algebra, which generalizes the construction of the Koszul-BGG resolution by Berest-Etingof-Ginzburg and Gordon, and the calculation of its homology in type A. We also show in type A that the differentials in the Koszul-BGG complex are uniquely determined by the condition that they are nonzero homomorphisms of modules over the Cherednik algebra. Finally, our fourth result is the symmetry theorem, which identifies the quasispherical components in the representations with minimal support over the rational Cherednik algebras H_{m/n}(S_n) and H_{n/m}(S_m). In fact, we show that the simple quotients of the corresponding quasispherical subalgebras are isomorphic as filtered algebras. This symmetry has a natural interpretation in terms of invariants of torus knots.

title: Photoelektronenspektroskopische Analyse von Grenzflächen an Li+-Ionen-Modellzellen mit PEG und LiTFSI basierten organisch-anorganischen Hybridelektrolyten

description: Trockene Poly (Ethylen Oxid) basierte Polymermembrane bilden vielversprechende Elektrolyte, die Li+-Ionen-Batterien mit festen organisch-anorganischen Hybridelektrolyten ermöglichen könnten. Entscheidend für die Leistung sind die Oxidationsstabilität des PEOs an der Kathode und der innere Grenzflächenwiderstand zwischen PEO und der Li+-Ionen leitenden Keramik (Li7-xLa3Zr2-xTaxO12). In beiden Szenarien ist eine genaue Kenntnis der Grenzflächenbildung, d.h. von Reaktionen an den Grenzflächen und der Ausbildung elektrischer Doppelschichten, unumgänglich, die jedoch mit post mortem Methoden nicht messbar sind. Diese Arbeit bietet einen neuartigen Ansatz zur Studie von PEO + LiTFSI Grenzflächen zwischen LiCoO2 Kathoden, keramischen Elektrolyten der Granat-Klasse sowie zu Lithium Metallanoden auf Grundlage des oberflächenwissenschaftlichen Ansatzes. Durch ihre weiche Natur sind Polymere nicht dafür geeignet, mit Keramiken bei höheren Temperaturen oder im Plasma beschichtet zu werden, weshalb sie selbst als Dünnschicht auf die Keramikkathode aufgetragen werden müssen. Da Verfahren, wie Rotationsbeschichten, zu viele Verunreinigen aufweisen, wird das PEO in Form seines Oligomers PEG 2000 g/mol zusammen mit dem Leitsalz LiTFSI thermisch im Ultrahochvakuum direkt auf das Substrat aufgedampft und anschließend im Clustertool mit der Photoelektronenspektroskopie analysiert. Zusätzlich kommen ergänzende Methoden zur Charakterisierung wie die dynamische Differenzkalorimetrie, die thermogravimetrische Analyse, Massenspektroskopie und Rasterelektronenmikroskopie zum Einsatz, um die gleichen physikalischen Eigenschaften der PEG + LiTFSI Dünnschichten, wie für dicke PEO Membranen benötigt, zu garantieren. Darüber hinaus wird der Einfluss von LiF Beschichtungen auf dem LLZ(T)O berücksichtigt und deren Einfluss systematisch untersucht. In einem neuen Verfahren mit Hilfe einer Vibrationsbühne in der Abscheidekammer wird dann die planare 2D Beschichtung auf 3D Partikel Systeme übertragen. Auf Grundlage der XPS Ergebnisse werden alle relevanten Grenzflächen in der Modellzelle LiCoO2/PEG+LiTFSI/LLZ(T)O (+LiF)/Lithium anhand der auftretenden Reaktionsprodukte und der Ausbildung von Raumladungszonen und deren Ursprung diskutiert sowie deren Einfluss auf den Grenzflächenwiderstand eingeordnet. Ein zentraler Punkt der Diskussion sind die Möglichkeit von Elektronen und Li+-Ionen-Transfers über die Grenzfläche sowie der Einfluss von parasitären Zustanden in der Bandlücke und die daraus folgenden Oxidations- und Reduktionsreaktionen.

description: A new sulfonyl derivative (C26H25N3O2S2), N’-(4-(3-methyl-3-phenylcyclobutyl)−3-phenylthiazol-2(3H)-ylidene)benzenesulfonohydrazide, was prepared from a mixture of benzenesulfonylhydrazide and phenylisothiocyanate in ethanol. The 3 D crystal structure, unit-cell dimensions, space group and crystal system of compound were investigated by single-crystal X-ray diffraction (SCXRD). FT-IR spectrum in solid state was observed in the region 4000–400 cm−1 and the 1H and 13C NMR spectra were recorded in CDCl3 solution. In order to support the experimental results, the molecular geometry, vibrational frequencies, 1H and 13C chemical shifts in the ground state have been calculated by using the density functional method (DFT/B3LYP) together with 6-311 G+(d, p) basis set. A good linear correlation between experimental and theoretically predicted structural and spectral parameters was observed (R2∼0.9).

description: Currently, gold nanorods can be synthesized in a wide range of sizes. However, for intended biological applications gold nanorods with approximate dimensions 50 nm x 15 nm are used. We investigate by computer simulation the effect of particle dimensions on the optical and thermal properties in the context of the specific applications of photoacoustic imaging. In addition we discuss the influence of particle size in overcoming the following biophysical barriers when administrated in vivo: extravasation, avoidance of uptake by organs of the reticuloendothelial system, penetration through the interstitium, binding capability and uptake by the target cells. Although more complex biological influences can be introduced in future analysis, the present work illustrates that larger gold nanorods, designated by us as "nanobig rods", may perform relatively better at meeting the requirements for successful in vivo applications compared to their smaller counterparts which are conventionally used.

description: Results of structural characterization of (AlxGa1-x)2O3 single crystals grown from
the melt with Al content x up to 0.04 are presented. Bulk (AlxGa1-x)2O3 crystals were grown
by exploring the Czochralski method [1]. Transmission electron microscopy (TEM) was used
to investigate defect structure of the material with various composition, X-ray diffractometry
was used to measure Al content x, to inspect crystallography of the growth facets and to
characterize the structure quality of the samples. Possible types of defects were identified in
the samples with various composition including single dislocations, cracks, and low-angle
misorientation block boundaries. Measured full-width at half-maximum (FWHM) of rocking
curves of 200" confirmed high quality of the grown crystals.

description: At the tree level, the maximally helicity violating amplitudes of N gauge bosons in open superstring theory and of N gravitons in supergravity are known to have simple representations in terms of tree graphs. For superstrings, the graphs encode integral representations of certain generalized Gaussian hypergeometric functions of kinematic invariants while for supergravity, they represent specific kinematic expressions constructed from spinor-helicity variables. We establish a superstring/supergravity correspondence for this class of amplitudes, by constructing a mapping between the positions of gauge boson vertices at the disk boundary and the helicity spinors associated to gravitons. After replacing vertex positions by a larger set of N(N-3)/2 coordinates, the superstring amplitudes become (multiple) Mellin transforms of supergravity amplitudes, from the projective space into the dual Mellin space of N(N-3)/2 kinematic invariants. Similarly, inverse Mellin transforms transmute open superstrings into supergravity. We elaborate on the properties of multiple Mellin and inverse Mellin transforms in the framework of superstring/supergravity correspondence.

description: Cosmic microwave background measurements have pushed to higher resolution, lower noise, and more sky coverage. These data enable a unique test of the early universe's expansion rate and constituents such as effective number of relativistic degrees of freedom and dark energy. Using the most recent data from Planck and WMAP9, we constrain the expansion history in a model independent manner from today back to redshift z=10^5. The Hubble parameter is mapped to a few percent precision, limiting early dark energy and extra relativistic degrees of freedom within a model independent approach to 2-16% and 0.71 equivalent neutrino species respectively (95% CL). Within dark radiation, barotropic aether, and Doran-Robbers models, the early dark energy constraints are 3.3%, 1.9%, 1.2% respectively.

description: In this work we present cosmological N-body simulations of the Local Universe with initial conditions constrained by the Two-Micron Redshift Survey (2MRS) within a cubic volume of 180 Mpc/h side-length centred at the Local Group. We use a self-consistent Bayesian based approach to explore the joint parameter space of primordial density fluctuations and peculiar velocity fields, which are compatible with the 2MRS galaxy distribution after cosmic evolution. This method (the KIGEN-code) includes the novel ALPT (Augmented Lagrangian Perturbation Theory) structure formation model which combines second order LPT (2LPT) on large scales with the spherical collapse model on small scales. Furthermore we describe coherent flows with 2LPT and include a dispersion term to model fingers-of-god (fogs). These implementations are crucial to avoid artificial filamentary structures, which appear when using a structure formation model with 2LPT and data with compressed fogs. We assume LCDM cosmology throughout our method. The recovered initial Gaussian fields are used to perform a set of 25 constrained simulations. Statistically this ensemble of simulations is in agreement with a reference set of 25 simulations based on randomly seeded Gaussian fluctuations in terms of matter statistics, power-spectra and mass functions. Considering the entire volume, we obtain correlation coefficients of about 98.3% for the comparison between the simulated density fields and the galaxy density field in log-space with Gaussian smoothing scales of r_S=3.5 Mpc/h (74% for r_S=1.4 Mpc/h). The cross power-spectra show correlations with the galaxy distribution which weaken towards smaller length scales until they vanish at scales of 2.2-3.0 Mpc/h. The simulations we present provide a fully nonlinear density and velocity field with a high level of correlation with the observed galaxy distribution at scales of a few Mpc.

Radiatively Inefficient Accretion Flow Simulations with Cooling: Implications for Black Hole Transients

description: We study the effects of optically thin radiative cooling on the structure of radiatively inefficient accretion flows (RIAFs). The flow structure is geometrically thick, and independent of the gas density and cooling, if the cooling time is longer than the viscous timescale (i.e., $t_{\rm cool} \gtrsim t_{\rm visc}$). For higher densities, the gas can cool before it can accrete and forms the standard geometrically thin, optically thick Shakura-Sunyaev disk. For usual cooling processes (such as bremsstrahlung), we expect an inner hot flow and an outer thin disk. For a short cooling time the accretion flow separates into two phases: a radiatively inefficient hot coronal phase and a cold thin disk. We argue that there is an upper limit on the density of the hot corona corresponding to a critical value of $t_{\rm cool}/t_{\rm ff} (\sim 10-100)$, the ratio of the cooling time and the free-fall time. Based on our simulations, we have developed a model for transients observed in black hole X-ray binaries (XRBs). An XRB in a quiescent hot RIAF state can transition to a cold black-body dominated state because of an increase in the mass accretion rate. The transition from a thin disk to a RIAF happens because of mass exhaustion due to accretion; the transition happens when the cooling time becomes longer than the viscous time at inner radii. Since the viscous timescale for a geometrically thin disk is quite long, the high-soft state is expected to be long-lived. The different timescales in black hole transients correspond to different physical processes such as viscous evolution, cooling, and free-fall. Our model captures the overall features of observed state transitions in XRBs.

description: In this paper we present an optimization approach to assessing the performance of service organizations from an Efficiency Analysis standpoint. In what concerns the empirical illustration, even though the paper employs data from a sample of Decision Making Units (DMUs) pertaining to a public system of academic libraries, there is no loss of generality if and when other kinds of organizations are considered. Summing up, our approach combines in a simple way efficiency scores computed from the estimation of selected Data Envelopment Analysis (DEA) models and a long run evaluation provided by Markovian analysis. The Markovian approach provides better knowledge concerning the time delay required for efficiency to be attained for the first time when a prescribed operation plan happens to be adopted. The text is organized in five sections that include this introduction. The second section brings together some background ideas and results that helped found the paper. In the next section the methodological procedure is explained, followed by empirical findings in the fourth section. Conclusions, limitations and pending issues are presented to close the text.
Helical Andreev bound states and superconducting Klein tunneling in topological insulator Josephson junctions

description: Currently, much effort is being put into detecting unconventional p-wave superconductivity in Josephson junctions based on topological insulators (TIs). For that purpose we propose to use superconducting Klein tunneling, i.e. the reflectionless passage of Cooper pairs through a potential barrier in a gated ballistic junction. This phenomenon occurs due to the fact that the supercurrent is carried by helical Andreev bound states (ABSs) characterized by spin-momentum locking similar to the normal-state carriers. We derive the spectrum of the helical ABSs and the corresponding Josephson current for a junction made on the surface of a three-dimensional TI. The superconducting Klein tunneling is predicted to yield a non-sinusoidal current-phase relation and an anomalous critical current $I_c$ that does not vanish with increasing barrier strength. We also analyze the dependence of the I_cR_n product (where R_n is the normal-state junction resistance) on the microscopic parameters of the superconductor/TI interface, which leads to lower I_cR_n values than expected from previous models of the proximity-effect Josephson junctions.

description: Neurodegenerative disorders such as Alzheimer's disease (AD) present a significant global health challenge, characterized by cognitive decline, functional impairment, and other debilitating effects. Current AD clinical trials often assess multiple longitudinal primary endpoints to comprehensively evaluate treatment efficacy. Traditional methods, however, may fail to capture global treatment effects, require larger sample sizes due to multiplicity adjustments, and may not fully exploit multivariate longitudinal data. To address these limitations, we introduce the Longitudinal Rank Sum Test (LRST), a novel nonparametric rank-based omnibus test statistic. The LRST enables a comprehensive assessment of treatment efficacy across multiple endpoints and time points without multiplicity adjustments, effectively controlling Type I error while enhancing statistical power. It offers flexibility against various data distributions encountered in AD research and maximizes the utilization of longitudinal data. Extensive simulations and real-data applications demonstrate the LRST's performance, underscoring its potential as a valuable tool in AD clinical trials.

description: Despite significant advances in many countries, as measured by the degree of commercial bank progress and development. This investigation and assessment of its credit activities became essential in order to ensure the quality and effectiveness of the organisation. Whereas, credit is one of the most critical tasks, ensuring the significance of assessment. The research aims to study and analyze credit banking which be applied at one of the commercial banks that operating in Libya (Sahara Bank). Commercial banks simply do not move away from their role as a financial mediator, allocating financial resources to fulfil diverse demands in order to make a profit. The main results of the study followed: a) the lower on the risk index of non-payment for loans and burdens and the lower of the safety margins to meet the risk of the loans. b) Despite the importance of measuring the cost of each activity separately to make sure of its efficiency and to keep track of any problems that may encounter this activity and affect its profit, but the accounting system that used does not provide data and information on the costs of each revenue activity. The Sahara Bank's most essential suggestions include evaluating risk lending in order to offer meaningful periodic information and effectively establishing an accounting system, as well as the necessity to scientifically and practically offer competent human cadres.

description: We assess the dependence on substrate dimensionality of the asymptotic scaling behavior of a whole family of equations that feature the basic symmetries of the Kardar-Parisi-Zhang (KPZ) equation. Even for cases in which, as expected from universality arguments, these models display KPZ values for the critical exponents and limit distributions, their behavior deviates from KPZ scaling for increasing system dimensions. Such a fragility of KPZ universality contradicts naive expectations, and questions straightforward application of universality principles for the continuum description of experimental systems.

description: The presence of ferroelectricity in hexagonal (h-)InMnO3 has been highly under debate. The results of our comprehensive experiments of low-temperature (T) polarization, TEM and HAADF-STEM on well-controlled h-InMnO3 reveal that the ground state is ferroelectric with P6_3cm symmetry, but a non-ferroelectric P-3c1 state exists at high T, and can be quenched to room T. We also found that the ferroelectric P6_3cm state of h-InMnO3 exhibits the domain configuration of topological vortices, as has been observed in h-REMnO3 (RE=rare earths).

title: Numerical Analysis of Thermal Distributions and Localized Melting in Solids
Creators: name: Unkelbach, Wilhelm
Publisher: name: UNSPECIFIED

description: Analytic solutions for heat transfer problems are limited to simple geometries and boundary conditions. This thesis aims to investigate numerical methods for solving transient heat transfer problems, with particular emphasis on problems involving localized heating that can lead to phase change. Such problems are of increasing importance in modelling additive manufacturing processes. Heat transfer is present in most engineering applications. Complex problems require numerical solutions which involve complex geometries, non-uniform boundary conditions and transient temperature history. For such problems, finite difference and finite element solution techniques have been developed. This thesis introduces the basic numerical models for finite difference and finite element calculations. Then the found calculation problems are employed to solve validation problems and generic heat transfer problems. A comparison is drawn to commercial code, namely Abaqus. Finally, melting and freezing processes are modelled and evaluated.

description: We examine the validity of fluctuation-dissipation relations in isolated quantum systems taken out of equilibrium by a sudden quench. We focus on the dynamics of trapped hard-core bosons in one-dimensional lattices with dipolar interactions whose strength is changed during the quench. We find that fluctuation-dissipation relations hold if the system is nonintegrable after the quench. They also hold if the system is integrable after the quench if the initial state is an equilibrium state of a nonintegrable Hamiltonian. However, they fail if the system is integrable both before and after quenching.

description: Постановка проблемы. В интересах выполнения процедур параметрического синтеза помех радиолокационным системам наведения управляемых ракет (УР) в динамике радиоэлектронного конфликта требуется формирование прогнозной модели (ПМ) контура наведения ракеты на основе результатов его идентификации.
Цель. Исследовать процесс идентификации контуров наведения УР и оценить временной интервал, в течение которого сохраняется высокая достоверность прогнозируемых координат УР.
Результаты. Рассмотрена процедура синтеза ПМ контура наведения УР с использованием результатов измерения ее фазовых координат после подачи на вход контура специального воздействия. Проведена оценка качества прогнозирования поведения ракеты по показателю «индекс корреляции действительных и прогнозируемых с использованием модели значений выходного сигнала контура наведения». Показано, что для типовых ПМ время их синтеза (идентификации) не превышает 0,8…1,2 с, а время прогнозирования координат УР с достоверностью 0,95 составляет не менее 80% от времени конфликта, что достаточно для реализации оптимальных помеховых воздействий.
Практическая значимость. Применение ПМ контуров наведения ракет, формируемых на основе их параметрической идентификации с использованием рекуррентного метода наименьших квадратов (РМНК), обеспечивает высокое качество прогнозирования поведения ракеты практически на все время ее конечного наведения и позволяет реализовать выбор оптимальных помеховых воздействий в динамике радио-электронного конфликта.

description: In this paper we develop a time reversal method for the radiative transport equation to solve two problems: an inverse problem for the recovery of an initial condition from boundary measurements, and the exact boundary controllability of the transport field with finite steering time. Absorbing and scattering effects, modeled by coefficients with low regularity, are incorporated in the formulation of these problems. This time reversal approach leads to a convergent iterative procedure to reconstruct the initial condition provided that the scattering coefficient is sufficiently small in the $L^{\infty}$ norm. Then, using duality arguments, we show that the solvability of the inverse problem leads to exact controllability of the transport field with minimum-norm control obtained constructively. The solution approach to both of these problems may have medical applications in areas such as optical imaging and optimization of radiation delivery for cancer therapy.

description: We study effects of delay in diffusively coupled logistic maps on the Cayley tree networks. We find that smaller coupling values exhibits sensitiveness for value of delay, and leads to different cluster patterns of self-organized and driven types. Whereas larger coupling strengths are very robust against change in delay values, and leads to stable driven clusters comprising only nodes from last generation of the Calaye tree. Furthermore, introduction of delay exhibits suppression as well as enhancement of synchronization depending upon coupling strength values, hence demonstrating richness of the model. To the end we relate the results with social conflicts and cooperation observed in families.

description: Influenced by the current trend of experimental data, especially from the LHC, we construct a supersymmetric scenario where a natural dynamics makes the squarks and gluino super-heavy (order 10 TeV) while keeping the sleptons and the weak gauginos light (100-500 GeV). The dynamics relies on the interfusion of two underlying ideas: ($i$) gauge mediation of supersymmetry breaking with two messenger multiplets, one transforming as a triplet of weak SU(2) and the other as an octet of color SU(3); ($ii$) perturbative gauge coupling unification at the string scale even with these incomplete SU(5) multiplets. Interestingly, the relative magnitude of the triplet and octet messenger scales that ensures gauge unification at the two-loop level also helps to naturally keep the uncolored superpartners light while making the colored ones heavy.

description: Постановка проблемы. К настоящему времени нет удовлетворительного решения задачи оперативного оценивания произвольных линейных числовых характеристик измеряемого выхода многомерного динамического объекта по результатам некорректных наблюдений, содержащих сингулярную помеху.
Цель. Разработать с использованием конечно-спектральных представлений (в конечном базисе заданных базисных функций) метод численно-аналитического описания решения уравнения, задающего динамический объект и его измеряемый выход, а также вычисления значений непрерывных линейных функционалов (числовых характеристик) от измеряемых параметров на основе некорректных наблюдений, не прибегая к традиционному расширению пространства состояний.
Результаты. Предложен метод построения численно-аналитического описания решения многомерного дифференциального уравнения объекта, его измеряемого выхода и оптимального несмещенного оценивания числовых характеристик без расчета спектральных коэффициентов в линейных комбинациях базисных функций, а также приведен иллюстративный пример, подтверждающий их эффективность.

description: We present a series of smoothed particle hydrodynamical models of G0.253+0.016 (also known as 'The Brick'), a very dense molecular cloud that lies close to the Galactic Centre. We explore how its gas and dust temperatures react as we vary the strength of both the interstellar radiation field (ISRF) and the cosmic ray ionisation rate (CRIR). As the physical extent of G0.253+0.016 along our line-of-sight is unknown, we consider two possibilities: one in which the longest axis is that measured in the plane of the sky (9.4 pc in length), and one in which it is along the line of sight, in which case we take it to be 17 pc. To recover the observed gas and dust temperatures, we find find that the ISRF must be around 1000 times the solar neighbourhood value, and the CRIR must be roughly 1E-14 /s, regardless of the geometries studied. For such high values of the CRIR, we find that cooling in the cloud's interior is dominated by neutral oxygen, in contrast to standard molecular clouds, which at the same densities are mainly cooled via CO. Our results suggest that the conditions near G0.253+0.016 are more extreme than those generally accepted for the inner 500 pc of the galaxy.

description: The jamming transition of frictionless athermal particles is a paradigm to understand the mechanics of amorphous materials at the atomic scale. Concepts related to the jamming transition and the mechanical response of jammed packings have cross-fertilized into other areas such as atomistic descriptions of the elasticity and plasticity of glasses. In this perspective article, the microscopic mathematical theory of the jamming transition is reviewed from first-principles. The starting point of the derivation is a microscopically-reversible particle-bath Hamiltonian from which the governing equation of motion for the grains under an external deformation is derived. From this equation of motion, microscopic expressions are obtained for both the shear modulus and the viscosity as a function of the distance from the jamming transition (respectively, above and below the transition). Regarding the vanishing of the shear modulus at the unjamming transition, this theory, as originally demonstrated in [Zaccone & Scossa-Romano, Phys. Rev. B 83, 184205 (2011)], is currently the only quantitative microscopic theory in parameter-free agreement with numerical simulations of [O'Hern et al. Phys. Rev. E 68, 011306 (2003)] for jammed packings. The divergence of the viscosity upon approaching the jamming transition from below is derived here, for the first time, from the same microscopic Hamiltonian. The quantitative microscopic prediction of the diverging viscosity is shown to be in fair agreement with numerical results of sheared 2D soft disks from [Olsson & Teitel, Phys. Rev. Lett. 99, 178001 (2007)].

description: Постановка проблемы. В известных работах по триангуляции, как правило, ограничиваются лишь рассмотрением потенциальных возможностей оптимальных и квазиоптимальных методов оценивания местоположения источника излучения для плоского случая. При этом вне поля зрения остаются вычислительные аспекты реализации данных методов в реальной компьютерной среде с учетом выбранного алгоритма численной оптимизации, а также отсутствует сравнительный анализ таких алгоритмов по точности и оперативности расчетов.
Цель. Провести сравнительный анализ известных и новых методов решения задачи триангуляции с учетом «овражности» целевых функций для пространственного случая, дать соответствующие оценки по точности и оперативности рассматриваемых методов при их реализации в компьютерной среде.
Результаты. Получены алгоритмы оптимального пространственного оценивания местоположения источника излучения для рассматриваемых альтернативных методов и с помощью математического моделирования для каждого из методов установлены количественные характеристики точности и оперативности, приведена таблица их сравнения.
Практическая значимость. Полученные результаты могут служить основой для выбора того или иного метода триангуляции с учетом условий наблюдения источников наблюдения, а также для разработки комплексного алгоритма оценивания местоположения и других параметров движения этих источников с учетом достоинств и недостатков рассмотренных альтернативных методов триангуляции.
