description: Постановка проблемы.При выборе температурных режимов нагревательных печей черной металлургии целесообразно ис-пользовать модели нагрева металла. Однако в настоящее время часто игнорируется проблема привлечения накопленной технологической информации к выбору структуры и настройке модели, что требует изучения.
Цель.Настроитьмодель нагрева металла, которая является адекватной к задачам управления нагревом металла и может быть настроена с применением накопленной технологической информации.
Результаты.На примере модели отжига стальной полосы в протяжных печах показано, что при переходе к приращениям данных с целью устранения влияния неконтролируемых возмущений. Принятая вариация структуры модели не оказывает значимого влияния на ошибку настройки модели. В то же время выбор структуры должен осуществляться, исходя из адекватности в статистическом смысле или по эффективности применения самонастраивающейся модели отжига металла при прогнозировании возмущений на основе экстраполяции во времени.
Практическая значимость.Рекомендации по выбору структуры модели отжига полосы могут использоваться при разработке систем управления температурным состоянием протяжных печей на агрегатах непрерывного горячего оцинкования.

description: The sources of different pollutants contributing to ambient PM2.5 in the Banja Luka (Bosnia and Herzegovina) suburban area were estimated. From January 2016 to March 2017, a total of 140 daily PM2.5 filter samples were collected and analyzed by complementary nondestructive analytical techniques. Concentrations of Na, Mg, Al, Si, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Br, Rb, Sr, and Pb were determined by energy dispersive X-ray fluorescence technique while black carbon concentration was estimated using multi-wavelength absorption optical measurements. Evaluation of the emission sources was performed based on the obtained PM2.5 composition data using positive matrix factorization model. The results indicate five main groups of sources contributing to the annual mean PM2.5 concentration (38.7 µg/m3): secondary sulfur/coal combustion 35.4% (11.8 µg/m3), biomass combustion 26.1. % (9.2 µg/m3), road salts/heavy oil 21.2% (7.5 µg/m3), soil dust 1.1% (0.4 µg/m3) and traffic emissions less than 0.05%. Black carbon originating from diesel fuel and biomass burning was differentiated by applied optical technique and included into PMF analysis. The approach and results of the field study are unique and significant contribution to the air quality management in this area. Copyright © 2022 American Association for Aerosol Research

description: На примере воды показано, что контроль изменения тангенса угла потерь является высокочувствительным методом, позво-ляющим с высокой точностью определять величину энергии активации релаксационных процессов в наноструктурированной воде. Обосновано использование датчиков, электроды которых не соприкасаются непосредственно с изучаемой жидкостью, а также условия получения достоверной информации о свойствах воды и ее растворов: измерения необходимо осуществлять импульсными методами, т.е. в течение нескольких секунд, после чего измерения прекращать во избежание загрязнения изу-чаемых растворов продуктами электролиза. Метод слежения за величиной тангенса угла потерь при фиксированных частотах позволяет одновременно контролировать кислотность растворов (величину рН) без использования специализированных приборов для изучения кислотности.

Analytical expressions for primary Bjerknes force on inertial cavitation bubbles
Creators: name: Louisnard, Olivier
Publisher: name: arXiv
Year: 2013
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: The primary Bjerknes force is responsible for the quick translational motion of radially oscillating bubbles in a sound field. The problem is classical in the case of small-amplitude oscillations, for which an analytical expression of the force can be easily obtained, and predicts attraction of sub- resonant bubbles by pressure antinodes. But for high-amplitude sound fields, the bubbles undergo large amplitude nonlinear oscillations, so that no analytical expression of the force is available in this case. The bubble dynamics is approximated on physical grounds, following the method of Hilgenfeldt et al. [J. Fluid Mech., 365, 171 (1998)], but carefully accounting for surface tension. The analytical expression of the maximum radius of the bubble is recovered, the time of maximum expansion is noticeably refined, and an estimation of the collapse-time is found. An analytical expression for the time-varying bubble volume is deduced, and the Bjerknes force is obtained in closed form. The result is valid for any shape of the sound field, including purely standing or purely traveling waves, and is ready to use in a theoretical model of bubble clouds evolution. Besides, the well-known sign inversion of the Bjerknes force for large standing waves is recovered and the inversion threshold in the parameter space is obtained analytically. The results are in good agreement with numerical simulation and allow a quantitative assessment of the physical parameters effect. It is found that either reducing surface tension, or increasing the static pressure, should produce a widening of the bubble-free region near high-amplitude pressure antinodes.
Predictive description of Planck-scale-induced spacetime fuzziness

description: Several approaches to the quantum-gravity problem predict that spacetime should be "fuzzy", but have been so far unable to provide a crisp physical characterization of this notion. An intuitive picture of spacetime fuzziness has been proposed on the basis of semi-heuristic arguments, and in particular involves an irreducible Planck-scale contribution to the uncertainty of the energy of a particle. These arguments also inspired a rather active phenomenological programme looking for blurring of images of distant astrophysical sources that would result from such energy uncertainties. We here report the first ever physical characterization of spacetime fuzziness derived constructively within a quantum picture of spacetime, the one provided by spacetime noncommutativity. Our results confirm earlier heuristic arguments suggesting that spacetime fuzziness, while irrelevantly small on terrestrial scales, could be observably large for propagation of particles over cosmological distances. However, we find no Planck-scale-induced lower bound on the uncertainty of the energy of particles, and we observe that this changes how we should picture a quantum spacetime and also imposes a reanalysis of the associated phenomenology.

description: Sensing schemes based on Rayleigh anomalies (RAs) in metal nanogratings exhibit an impressive bulk refractive-index sensitivity determined solely by the grating period. However, the surface sensitivity (which is a key figure of merit for label-free chemical and biological sensing) needs to be carefully investigated to assess the actual applicability of this technological platform. In this paper, we explore the sensitivity of RAs in metal nanogratings when local refractive-index changes are considered. Our studies reveal that the surface sensitivity deteriorates up to two orders of magnitude by comparison with the corresponding bulk value; interestingly, this residual sensitivity is not attributable to the wavelength shift of the RAs, which are completely insensitive to local refractive-index changes, but rather to a strictly connected plasmonic effect. Our analysis for increasing overlay thickness reveals an ultimate surface sensitivity that approaches the RA bulk value, which turns out to be the upper-limit of grating-assisted surface-plasmon-polariton sensitivities.

description: Постановка проблемы. Важная роль в решении проблемы достижения высокого быстродействия и повышения степени интеграции отводится внедрению новых нанотранзисторных архитектур. Одной из привлекательных является конструкция кремниевого полевого транзистора с полностью охватывающим затвором. Применение такой архитектуры перспективно и для более весомого подавления коротко-канальных эффектов и для улучшения транспорта носителей в транзисторе.
Цель работы – разработка комплекса математических моделей для расчетов электрических и тепловых характеристик суб-50 нм кремниевого полевого транзистора с полностью охватывающим затвором, выполненных по технологии кремний-на изоляторе.
Результаты. Разработана математическая модель распределения потенциала, вытекающая из аналитического решения 2D-уравнения Пуассона в цилиндрических координатах. Результаты модельных расчетов распределения потенциала суб-50 нм структур находятся в хорошем соответствии с данными, полученными при помощи коммерчески доступного программного пакета ATLASTM, предназначенного для 2D-моделирования транзисторных структур.
Разработана токовая модель транзистора при помощи апробированного подхода, сформулированного в рамках зарядового разделения и полученных распределений потенциала. По результатам численного моделирования показано, что ток прототипа транзистора в режиме сильной версии достаточно высок, а чувствительность вольт-амперных характеристик к уровню затворного напряжения примерно в два раза выше по сравнению с аналогичной характеристикой двухзатворного кремниевого полевого нанотранзистора с теми же топологическими параметрами. Разработана математическая модель распределения температуры в подложке под транзистором с учетом использования теплопроводящего столбика из диэлектрика La5Ca9Cu24O41 с высокой анизотропной теплопроводностью, который решает проблему улучшения терморегуляции. Разработан способ использования теплопроводящих столбиков, которые размещаются вместо одного из транзисторов и опираются, что важно, на кремневую подложку. Результаты численного моделирования показывают, что скорость роста температуры при планомерном возрастании рассеиваемой мощности для конструкции с термостолбиком и без него отличаются примерно в 1,5 раза: 0,16 мхK/Вт против 0,24 мхK/Вт, соответственно. Это обусловливает существенно более низкую температуру микросхемы с термостолбиком по сравнению с той же схемой, но без него.
Практическая значимость. Разработанные модели и полученные результаты могут быть использованы для перехода на новые конфигурации современных высокоэффективных нанотранзисторных интегральных схем.

description: Automatic crack detection is a main task in a crack map generation of the existing concrete infrastructure inspection. This paper presents an automatic crack detection and classification method based on genetic algorithm (GA) to optimize the parameters of image processing techniques (IPTs). The crack detection results of concrete infrastructure surface images under various complex photometric conditions still remain noise pixels. Next, a deep convolution neural network (CNN) method is applied to classify crack candidates and non-crack candidates automatically. Moreover, the proposed method is compared with the state-of-the-art methods for crack detection. The experimental results validate the reasonable accuracy in practical application. The final purpose was to create crack map therefore requiring the pixel-level accuracy automatically.

title: Continuous Monitoring of Environmental Disturbances by Cumulative Sums of Dense SAR Satellite Timeseries
Creators: name: Ruiz Ramos, Javier
Publisher: name: The Open University
Year: 2023

description: Climate change together with growing socio-economic pressures are leading to a significant increase in alterations to natural ecosystems. The alteration of natural cycles and dynamics through the direct destruction or continuous degradation, are threatening the conservation of these natural spaces on a global scale. Satellite remote sensing is a suitable solution for large-scale monitoring and evaluation of natural landscapes under threat, as it provides a consistent source of information for both historical and updated environmental studies. However, most current remote sensing-based environmental monitoring tools still present certain limitations which hinder access to continuous and real-time information. The design and development of new methods and approaches to environmental remote sensing is required to mitigate the current environmental degradation trends. This thesis analyses the current challenges associated with environmental monitoring to focus on the development of new change detection methods applied to the study of environmental disturbances in highly dynamic natural ecosystems. By exploiting the frequent monitoring capabilities of Synthetic Aperture Radar (SAR) dense timeseries, this research introduces new approaches based on Cumulative Sum (CuSum) strategies for continuous and near-real-time investigation. These approaches have been applied to monitor permanent and cyclical disturbances in highly threatened forest and wetland ecosystems. The main scientific contribution of this thesis is the introduction of three novel SAR-based change detection approaches capable of exploiting dense satellite imagery time series for continuous and near-real-time monitoring. The outcome of this research provides environmental managers with a fully operational alternative tool capable of rapid and continuous monitoring of environmental dynamics.

description: We investigate magnetic properties of strongly interacting bosonic mixtures confined in one dimensional geometries, focusing on recently realized Rb-K gases with tunable interspecies interactions. By combining analytical perturbation theory results with density-matrix-renormalization group calculations, we provide quantitative estimates of the ground state phase diagram as a function of the relevant microscopic quantities, identifying the more favorable experimental regimes in order to access the various magnetic phases. Finally, we qualitatively discuss the observability of such phases in realistic setups when finite temperature effects have to be considered.

description: Safety-Critical Java (SCJ) is a recent technology that restricts the execution and memory model of Java in such a way that applications can be statically analysed and certified for their real-time properties and safe use of memory. Our interest is in the development of comprehensive and sound techniques for the formal specification, refinement, design, and implementation of SCJ programs, using a correct-by-construction approach. As part of this work, we present here an account of laws and patterns that are of general use for the refinement of SCJ mission specifications into designs of parallel handlers used in the SCJ programming paradigm. Our notation is a combination of languages from the Circus family, supporting state-rich reactive models with the addition of class objects and real-time properties. Our work is a first step to elicit laws of programming for SCJ and fits into a refinement strategy that we have developed previously to derive SCJ programs.

description: Linear analysis of the formation of protostellar cores in planar magnetic interstellar clouds yields information about length scales involved in star formation. Combining these length scales with various distributions of other environmental variables, (i.e., column density and mass-to-flux ratio) and applying Monte Carlo methods allow us to produce synthetic core mass functions (CMFs) for different environmental conditions. Our analysis shows that the shape of the CMF is directly dependent on the physical conditions of the cloud. Specifically, magnetic fields act to broaden the mass function and develop a high-mass tail while ambipolar diffusion will truncate this high-mass tail. In addition, we analyze the effect of small number statistics on the shape and high-mass slope of the synthetic CMFs. We find that observed core mass functions are severely statistically limited, which has a profound effect on the derived slope for the high-mass tail.

Along the way, we also describe the features of the brane energy momentum tensors, the equations of motion, and their solutions which arise as consequences of the intersection rules and the U duality symmetries of M theory.

description: The response of plants to grazing includes the production of chemical defense compounds such as proteases inhibitors and secondary metabolites as flavonoids, which makes them less palatable to feeding and negatively affecting the physiology of insects. This study aimed to evaluate the phytochemical response of soybean cultivars Glycine max resistant (IAC-17, IAC-24) and susceptible (IAC-P1) to insects after mechanical damage. These cultivars were mechanically injured, and after 24 hours samples of these plants were analyzed by HPLC to identify and quantify flavonoids. The flavonoids daidzein, quercetin, and rutin were quantified, with the highest concentration of daidzin in soybean cultivars after mechanical damage. Rutin was biosynthesized by IAC-24. The cultivars IAC-PL1, IAC-17, and IAC-24 did not show a flavonoid response to mechanical damage. The soybean cultivars are not dependent on mechanical damage to produce flavonoids.

description: Object-oriented (OO) inheritance allows the definition of families of classes in a hierarchical way. In behavioural inheritance, a strong version, it should be possible to substitute an object of a subclass for an object of its superclass without any observable effect on the system. Behavioural inheritance is related to formal refinement, but, as observed in the literature, the refinement constraints are too restrictive, ruling out many useful OO subclassings. This paper studies behavioural inheritance in the context of ZOO, an object-oriented style for Z. To overcome refinement's restrictions, this paper proposes relaxations to the behavioural inheritance refinement rules. The work is presented for Z, but the results are applicable to any OO language that supports design-by-contract.

Разработка чувствительных, помехозащищенных антенн, выполненных в виде монолитных инте-гральных схем и работающих в широкой полосе частот, позволит увеличить вариативность схемотехнических решений при разработке современных радиотехнических систем и, тем самым, обеспечить их оптимальные характеристики.
Цель работы – рассмотреть варианты исполнения широкополосной антенны-аппликатора СВЧ-диапазона.
Результаты. Рассмотрена антенна дипольного типа, отличающаяся от известных вариантов классического симметричного диполя новым способом возбуждения. При отсутствии в конструкции предложенной антенны поглощающих материалов ширина полосы ее согласования с фидерным трактом имеет полосу перекрытия частот по диапазону более чем 10:1.

Standardized short-term toxicological procedures as well as methods quantifying potential toxic effects over the whole life span of an animal are required. We studied the effect of the microplastic polystyrene on the survival and reproduction of a common freshwater invertebrate, the rotifer Brachionus calyciflorus, at different timescales. We used pristine polystyrene spheres of 1, 3, and 6 µm diameter and fed them to the animals together with food algae in different ratios ranging from 0 to 50% nonfood particles. As a particle control, we used silica to distinguish between a pure particle effect and a plastic effect. After 24 h, no toxic effect was found, neither with polystyrene nor with silica. After 96 h, a toxic effect was detectable for both particle types. The size of the particles played a negligible role. Studying the long-term effect by using life table experiments, we found a reduced reproduction when the animals were fed with 3 µm spheres together with similar-sized food algae. We conclude that the fitness reduction is mainly driven by the dilution of food by the nonfood particles rather than by a direct toxic effect.

description: In this paper, we study the initial-value problem for two first order systems in non-conservative form. The first system arises in elastodynamics and belongs to the class of strictly hyperbolic, genuinely nonlinear systems. The second system has repeated eigenvalues and an incomplete set of right eigenvectors. Solutions to such systems are expected to develop singular con- centrations. Existence of singular solutions to both the systems have been shown using the method of weak asymptotics. The second system has been shown to develop singular concentrations even from Riemann-type initial data. The first system differing from the second in having an extra term containing a positive constant k, the solution constructed for the first system have been shown to converge to the solution of the second as k tends to 0.

description: This article addresses the application of pyrgeometers, pyranometers and some basic weather parameters to evaluate cloud base height, cloud base temperature, and cloud coverage at local scale throughout the year. The ground-based laser beam ceilometers are used at the Automated Surface Observing Systems (ASOS) in major airports in the U.S. to measure the cloud base height and report the sky conditions on an hourly basis or at shorter intervals. These laser ceilometers are fixed-type whose transmitters and receivers point straight up at the cloud (if any) base. They are unable to detect clouds that are not above the sensor. To report cloudiness at the local scale, many of these types of ceilometers are needed. A single cloud hanging over the sensor will cause overcast readings, whereas, a hole in the clouds above the sensor could cause a clear reading to be reported. To overcome this problem, we have set up a ventilated radiation station at Logan - Cache airport, Utah, U.S .A., since 1995. This airport is equipped with one of the above-mentioned ceilometers. This radiation station (composed of pyranometers, pyrgeometers with fields of view of 150o), and net radiometer provide continuous measurements of incoming and outgoing shortwave and longwave radiation and net radiation throughout the year. Considering the additional longwave radiation captured by the facing-up pyrgeometer during cloudy skies, coming from the cloud in the wave band (8-13 μm) which the gaseous emission lacks, we developed an algorithm which provides the continuous cloud information (cloud base height, cloud base temperature, and percent of skies covered by cloud) at local scale during the day and night throughout the year. Comparisons between the ASOS and the model data during the period June, 2004, are reported in this article. The proposed algorithm is a promising approach for evaluation of the cloud base temperature and height, and percent of skies covered by cloud and its effects on aviation throughout the year. Having enough pyrgeometers and the necessary surface weather parameters, the study can be expanded to regional scale for continuous evaluation of clouds.

description: Driven condensed matter systems consistently pose substantial challenges to theoretical understanding. Progress in the study of such systems has been achieved using the Floquet formalism, but certain aspects of this approach are not well understood. In this paper, we consider the exceptionally simple case of the rotating Kekulé mass in graphene through the lens of Floquet theory. We show that the fact that this problem is gauge-equivalent to a time-independent problem implies that the "quasi-energies" of Floquet theory correspond to a continuous symmetry of the full time-dependent Lagrangian. We use the conserved Noether charge associated with this symmetry to recover notions of equilibrium statistical mechanics.

Study on Principle Extremum of Full Action

description: The Lagrange formalism on dissipative systems is extended by a new variational principle extremum of full action. This principle can be applied to electrical engineering and mechanics when friction forces are taken into account.It also mentions its usefulness to electrodynamics and hydrodynamics. The proposed variational principle can be thought of as a novel formalism for deriving physical equations that can also be used to solve them. The approach entails creating a functional with a single saddle line, and the equation that characterises it represents an equation with dynamic variables for a specific physics domain. A search for a global saddle line for specified conditions of a physical problem is used as the solution approach. Earlier work on this topic see [1,2,3].
What the top asymmetries tell us about single top production and Higgs decays

description: The top asymmetries measured at the Tevatron, and the discrepancy in the di-photon Higgs rate under investigation at the LHC represent two possible hints of physics beyond the Standard Model (SM). In this paper we address the possibility to explain and relate both these experimental anomalies with the help of an extra scalar doublet in addition to the SM particle spectrum. The connection is provided by the constraints that the electroweak precision tests impose on the oblique S and T parameters. As a result, considering the semi-leptonic single top production in the tW-channel at the LHC, our analysis predicts a bump in the invariant mass distribution of the two light jets.

A Brief Overview of Gbagyi Beyekpe (Education) and Imperialism in Minna 1928 – 1960

description: The present chapter discussed the Gbagyi Beyekpe (education) and imperialism in Minna, 1928-1960. The contact of the Gbagyi in Minna with imperialism dates back to the early part of the twentieth century. As a result of the Gbagyi's interaction with imperial power, a new system of knowledge substituted the Gbagyi's Beyekpe (education), which was a process of educating the children and every individual for happy and productive living and to create the Gbagyi individual who will be honest, responsible, skilled, cooperative, and adhere to the social order of the day.This new order which was explicitly designed to restructure the social pattern of the Gbagyi and his society began in 1928 and by 1960 had replaced the Gbagyi Beyekpe (education). According to the study, this development ushered in the dependency syndrome that characterised Gbagyi modernity and continues to obstruct Gbagyi and his Minna society's evolution. The paper illustrated the influence of this alien knowledge system on the Gbagyi in Minna and argued for a redefinition of the Gbagyi knowledge system that is distinct from the western educational tradition, which stresses superiority as a measure of educational attainment holistically.

description: The complexity of modern software systems entails the need for reconfiguration mechanisms gov- erning the dynamic evolution of their execution configurations in response to both external stimulus or internal performance measures. Formally, such systems may be represented by transition systems whose nodes correspond to the different configurations they may assume. Therefore, each node is en- dowed with, for example, an algebra, or a first-order structure, to precisely characterise the semantics of the services provided in the corresponding configuration. Hybrid logics, which add to the modal description of transition structures the ability to refer to specific states, offer a generic framework to approach the specification and design of this sort of systems. Therefore, the quest for suitable notions of equivalence and refinement between models of hybrid logic specifications becomes fundamental to any design discipline adopting this perspective. This paper contributes to this effort from a distinctive point of view: instead of focussing on a specific hybrid logic, the paper introduces notions of bisimilarity and refinement for hybridised logics, i.e. standard specification logics (e.g. propositional, equational, fuzzy, etc) to which modal and hybrid features were added in a systematic way.

description: The use of 40Ca100MoO in experimental searches for neutrinoless double beta decay (0νDBD) relies on knowledge of fundamental scintillation properties of the material. In this work we determine the absolute light yield of calcium molybdate using Monte-Carlo refractive index matching technique (MCRIM). The MCRIM technique is a combination of experiment and simulations that allows the absolute light yield of scintillators to be determined by taking into account effects of refraction, scattering and absorption in the material. The light collection efficiency of the scintillator-detector assembly was simulated using the ZEMAX ray-tracing software. By tuning the optical parameters of the scintillation crystal, a model was derived that gives good agreement with the experimental results. It is shown that the light collection efficiency of scintillators increases with transmittance and scattering due to an enhanced probability for photons to escape the crystal volume. Using MCRIM, the absolute light yield for the 40Ca100MoO4 scintillator was found to be 7.5+-1.2 ph/keV at room temperature. Comparative measurements using a CaWO4 scintillator as a reference show good agreement with this result. In that way, the study demonstrated the potential of the MCRIM technique as a tool for quantitative characterization of scintillation materials.
The confinement induced resonance in spin-orbit coupled cold atoms with Raman coupling

description: We investigate the confinement induced resonance in spin-orbit coupled cold atoms with Raman coupling. We find that the quasi-bound levels induced by the spin-orbit coupling and Raman coupling result in the Feshbach-type resonances. For sufficiently large Raman coupling, the bound states in one dimension exist only for sufficiently strong attractive interaction. Furthermore, the bound states in quasi-one dimension exist only for sufficient large ratio of the length scale of confinement to three dimensional s-wave scattering length. The Raman coupling substantially changes the confinement-induced resonance position. We give a proposal to realize confinement induced resonance by increasing the Raman coupling strength in experiments.
