Ameisenalgorithmen. Optimierung und Modellierung [online]
Creators: name: Merkle, Daniel
Publisher: name: Karlsruhe
Year: 2002

description: Kurzfassung

Ameisenalgorithmen gehören zur Klasse der populationsbasierten
zufallsgesteuerten Suchverfahren für die Lösung kombinatorischer
Optimierungsprobleme und sind inspiriert von Vorgehensweisen,
die Ameisenkolonien bei der Suche nach Nahrung verwenden. Durch
indirekte Kommunikation mittels Duftstoffmarkierung gelangen die
Ameisen in einem Prozess der Wegoptimierung schnell zu
Nahrungsquellen. Im algorithmischen Analogon wählen künstliche
Ameisen im Entscheidungsgraphen des zugrunde liegenden
Optimierungsproblems iterativ Wege, die zunehmend besseren
Lösungen entsprechen.
In dieser Arbeit werden gezielt Verfahrensmodifikationen und
Erweiterungen der herkömmlichen Ameisenalgorithmen vorgestellt,
die für bestimmte Problemklassen zu einem deutlich besseren
Optimierungsverhalten führen.
Insbesondere betrifft dies die Auswertung der gespeicherten
Duftstoffinformation und die Entscheidungsreihenfolgen, die eine
künstliche Ameise beim Aufbau einer Lösung durchläuft. Die
erfolgreiche Anwendung der entwickelten Methoden wird jeweils
anhand einfacher Probleme gezeigt, die charakteristische
Eigenschaften schwieriger Probleme widerspiegeln, und
anschließend auf NP-vollständige Probleme übertragen. Die
Betrachtung des Problems der Projektplanung bei beschränkten
Ressourcen bezieht empirische Tests der Methoden an
Probleminstanzen einer bekannten Benchmark-Bibliothek ein. In
den Tests wurden die oberen Schranken für viele Instanzen
verbessert und im Vergleich zu anderen Verfahren im Durchschnitt
die besten Ergebnisse erzielt.
Probleme der Maschinenbelegung bei Beachtung mehrerer
konkurrierender Zielkriterien werden durch die Entwicklung von
Kooperationsmechanismen zwischen mehreren Kolonien von
künstlichen Ameisen erfolgreich gelöst.
Es wird ein deterministisches Modell für Ameisenalgorithmen
vorgestellt, das auf den erwarteten Aktualisierungswerten der
Duftstoffinformation basiert. Anhand dieses Modells können mit
Hilfe einer Fixpunktanalyse der in einer Matrix gespeicherten
Duftstoffinformation Aussagen über die Dynamik von
Ameisenverfahren für Permutationsprobleme getroffen werden. Das
Modellverhalten entspricht in vieler Hinsicht sehr gut dem
zufallsgesteuerten Ameisenalgorithmus und ermöglicht auch für
komplexe Optimierungsprozesse analytische Vorhersagen.

description: We show in the Skyrme-Hartree-Fock approach that unambiguous correlations exist between observables of finite nuclei and nuclear matter properties. Using this correlation analysis to existing data on the neutron skin thickness of Sn isotopes, we find important constraints on the value E_{sym}(rho_0) and density slope L of the nuclear symmetry energy at saturation density. Combining these constraints with those from recent analyses of isospin diffusion and double neutron/proton ratio in heavy ion collisions leads to a value of L=58\pm 18 MeV approximately independent of E_{sym}(ρ_0).

description: We present the results of near-infrared (NIR) multi-epoch observations of the optical transient in the nearby galaxy NGC300 (NGC300-OT) at 398 and 582 days after the discovery with the Infrared Camera (IRC) onboard AKARI. NIR spectra (2--5 um) of NGC300-OT were obtained for the first time. They show no prominent emission nor absorption features, but are dominated by continuum thermal emission from the dust around NGC300-OT. NIR images were taken in the 2.4, 3.2, and 4.1 um bands. The spectral energy distributions (SED) of NGC300-OT indicate the dust temperature of 810 (+-14) K at 398 days and 670 (+-12) K at 582 days. We attribute the observed NIR emission to the thermal emission from dust grains formed in the ejecta of NGC300-OT. The multi-epoch observations enable us to estimate the dust optical depth as larger than about 12 at 398 days and larger than about 6 at 582 days at 2.4 um, by assuming an isothermal dust cloud. The observed NIR emission must be optically thick, unless the amount of dust grains increases with time. Little extinction at visible wavelengths reported in earlier observations suggests that the dust cloud around NGC300-OT should be distributed inhomogeneously so as to not screen the radiation from the ejecta gas and the central star. The present results suggest the dust grains are not formed in spherically symmetric geometry, but rather in a torus, a bipolar outflow, or clumpy cloudlets.

description: A new "self-calibrated" statistical analysis method has been developed for the reduction of nulling interferometry data. The idea is to use the statistical distributions of the fluctuating null depth and beam intensities to retrieve the astrophysical null depth (or equivalently the object's visibility) in the presence of fast atmospheric fluctuations. The approach yields an accuracy much better (about an order of magnitude) than is presently possible with standard data reduction methods, because the astrophysical null depth accuracy is no longer limited by the magnitude of the instrumental phase and intensity errors but by uncertainties on their probability distributions. This approach was tested on the sky with the two-aperture fiber nulling instrument mounted on the Palomar Hale telescope. Using our new data analysis approach alone-and no observations of calibrators-we find that error bars on the astrophysical null depth as low as a few 10-4 can be obtained in the near-infrared, which means that null depths lower than 10-3 can be reliably measured. This statistical analysis is not specific to our instrument and may be applicable to other interferometers.

description: Population III star formation during the dark ages shifted from minihalos (~10^6 Msun) cooled via molecular hydrogen to more massive halos (~10^8 Msun) cooled via Ly-alpha as Lyman-Werner backgrounds progressively quenched molecular hydrogen cooling. Eventually, both modes of primordial star formation were suppressed by the chemical enrichment of the IGM. We present a comprehensive model for following the modes of Population III star formation that is based on a combination of analytical calculations and cosmological simulations. We characterize the properties of the transition from metal-free star formation to the first Population II clusters for an average region of the Universe and for the progenitors of the Milky Way. Finally, we highlight the possibility of observing the explosion of Population III stars within Ly-alpha cooled halos at redshift z~6 in future deep all sky surveys such as LSST.

description: We develop an analytical theory for diffusive random lasers by coupling the transport theory of the disordered medium to the semiclassical laser rate equations, accounting for (coherent) stimulated and (incoherent) spontaneous emission. From the causality of wave propagation in an amplifying, diffusive medium we derive a novel length scale which we identify with the average mode radius of the lasing quasi-modes. We show further that loss at the surface of the laser-active medium is crucial in order to stabilize a stationary lasing state. The solution of the transport theory of random lasers for a layer geometry with appropriate surface boundary conditions yields the spatial profile of the light intensity and of the population inversion. The dependence of the intensity correlation length on the pump rate is in qualitative agreement with experimental and numerical findings.

description: Additional file 1: Supplementary Figure S1. Sequential gating approach for the measurement of CCR2 expression by CD14+ monocytes. The sequential gating approached used was as follows: First, the viable (7-AAD negative; region ‘Viable”) cells were identified using a 7-AAD vs SS Log density plot. A “Viable” region was created around the 7-AAD negative cells. Gated on the “Viable”cells, a SSLog vs FS plot was used to capture intact cells in the “E” region. CD14+ monocytes were identified (“CD14+” region) using a CD14 vs SS Log density plot that were gated on viable, intact cells (“E” region). CD14+ monocytes that express CCR2 were quantified using a CD192 (CCR2) vs SS Log plot. The proportion of CD14+/CCR2+ cells were captured in the “CD14+ CCR2+” region. The gating strategy followed to quantify CCR2 expression by CD16+ neutrophils was similar to what was described for CD14+ monocytes, but instead of identifying CD14+ monocytes, CD16+ neutrophils were identified (“CD16+” region) using a CD16 vs SS Log density plot that were gated on viable, intact cells (“E” region). CD16+ neutrophils that express CCR2 were quantified using a CD192 (CCR2) vs SS Log plot. The proportion of CD14+/CCR2+ cells was captured in the “CD16+ CCR2+” region.

Characterizing Structure Through Shape Matching and Applications to Self Assembly

description: Structural quantities such as order parameters and correlation functions are often employed to gain insight into the physical behavior and properties of condensed matter systems. While standard quantities for characterizing structure exist, often they are insufficient for treating problems in the emerging field of nano and microscale self-assembly, where the structures encountered may be complex and unusual. The computer science field of "shape matching" offers a robust solution to this problem by defining diverse methods for quantifying the similarity between arbitrarily complex shapes. Most order parameters and correlation functions used in condensed matter apply a specific measure of structural similarity within the context of a broader scheme. By substituting shape matching quantities for traditional quantities, we retain the essence of the broader scheme, but extend its applicability to more complex structures. Here we review some standard shape matching techniques and discuss how they might be used to create highly flexible structural metrics for diverse systems such as self-assembled matter. We provide three proof-of-concept example problems applying shape matching methods to identifying local and global structures, and tracking structural transitions in complex assembled systems. The shape matching methods reviewed here are applicable to a wide range of condensed matter systems, both simulated and experimental, provided particle positions are known or can be accurately imaged.

Under pressure : biomechanics of buoyancy in Bull Kelp (Nereocystis leutkeana)
Creators: name: Liggan, Lauran
Publisher: name: University of British Columbia
Year: 2016

description: Maintaining buoyancy with pneumatocysts is essential for subtidal seaweeds with long flexible thalli, such as Nereocystis luetkeana (Nereocystis), to achieve an upright stature and compete for light. However, as Nereocystis grows, pneumatocysts are exposed to significant changes in hydrostatic pressure. Exposure to changing hydrostatic pressure could cause complications since the pneumatocyst is filled with gases that may expand or contract, potentially causing pneumatocysts to break, flood, and no longer be buoyant. This study explored how Nereocystis pneumatocysts resist biomechanical stress and keep the developing sporophyte upright in the water. Throughout development, pneumatocysts had an internal pressure consistently less than atmospheric pressure (3 – 100 kPa), indicating pneumatocysts always experience compressional loads. The structural integrity and design of the pneumatocyst to resist buckling was assessed by measuring compressional modulus (material stiffness), calculating material stress, analyzing critical geometry, and estimating critical buckling pressure. Small pneumatocysts found at depth (inner radius = 0.8 - 0.9 cm; wall thickness = 0.2 cm) were demonstrated to have reached a critical size in development and are at greatest risk of buckling. Pneumatocysts do not adjust material properties or geometry to reduce wall stress, but they are naturally resistant to hydrostatic loads. Critically small pneumatocysts are estimated to buckle at 35 m depth, which was observed to be sporophytes’ lower limit in the field. Data suggest that hydrostatic pressure, not just light limitation, might explain the maximum depth to which Nereocystis is capable of growing. Pneumatocyst gas composition did not change throughout development, and contrary to previous studies, internal gas concentrations were different from the atmosphere with O₂, N₂, CO, and CO₂ concentrations of 59%, 40%, 1.6%, and 0.6% respectively. Furthermore, pneumatocyst surface area to volume ratio did not correlate with the exchange of gases produced from photosynthesis and respiration. As sporophytes grow, total buoyant force is steadily outpaced by the weight of growing thalli, and the risk of the pneumatocyst sinking increases. Adult sporophytes are estimated to sink when pneumatocysts volume reaches 1.3 L, close to the maximum observed size in the field.
Reducing Image Artifacts in Motion Blur Prevention

Image processing

description: Motion blur is a form of image quality degradation, showing as content in the image smearing and not looking sharp. It is usually seen in photography due to relative motion between the camera and the scene (either camera moves or objects in the scene move). It is also seen in human vision systems, primarily on digital displays.
 It is often desired to remove motion blurriness from images. Numerous works have been put into reducing motion blur after the image has been formed, e.g., for camera-captured ones. Unlike post-processing methods, we take the approach to prevent/minimize motion blur for both human and camera observation by pre-processing the source image. The pre-processed images are supposed to look sharp upon blurring. Note that, only pre-processing methods can deal with human-observed blurriness since the imagery can't be modified after it is formed on the retina.
 Pre-processing methods face more fundamental challenges than post-processing ones. A problem inherent to such methods is the appearance of ringing artifacts which are intensity oscillations reducing the quality of the observed image. We found that these ringing artifacts have a fundamental cause rooted in the blur kernel. The blur kernel usually have very low amplitudes in some frequencies, significantly attenuating the signal intensity in these frequencies when it convolves an image. Pre-processing methods can usually reconstruct the targeted image to the observer but inevitably lose energy in those frequencies, appearing as artifacts. To address the artifact issue, we present a few approaches: (a) aligning the image content and the kernel in the frequency domain, and (b) redistributing their intensity variations elsewhere in the image. We demonstrate the effectiveness of our method in a working prototype, in simulation, and with a user study.

Были сделаны выводы о причинах снижения динамики поступления земельного налога. Результаты анализа неналоговых доходов имеют положительную динамику, однако ряд статей показал некую неопределенность, в частности, по доходам от аренды земли и имущества наблюдается стабильное падение этих доходов, а доходы от части прибыли муниципальных унитарных предприятий имеют стабильный тренд. В связи с нестабильностью поступления налоговых и неналоговых источников, отмечается рост безвозмездных поступлений в среднем на 30% ежегодно.Для исследования применялись такие общенаучные методы исследования, как формализация, теоретическое обобщение, анализа и синтеза, научной абстракции, метод экспертных оценок. В рамках обозначенных проблем, были сделаны предложения по увеличению доходной части городского бюджета по следующим направлениям: проведению мероприятий по повышению эффективности использования муниципального имущества, повышению эффективности финансово-хозяйственной деятельности муниципальных предприятий города, организации проведения информационно-разъяснительной работы с налогоплательщиками, совершенствованию муниципального земельного контроля и необходимости проведения оптимизации нормативной базы по налогам и сборам и оценке эффективности налоговых и неналоговых преференций. В ходе проведенных расчетов был спрогнозирован и обоснован рост доходных источников муниципального образования, что приведет к снижению бюджетной зависимости муниципального образования.

description: The presence of absorbing gas around the central engine of Active Galactic Nuclei (AGN) is a common feature of these objects. Recent work has looked at the effect of the dust component of the gas, and how it enhances radiation pressure such that dusty gas can have a lower effective Eddington limit than ionised gas. In this work, we use multi-wavelength data and X-ray spectra from the 2 Ms exposures of the Chandra Deep Field North and Chandra Deep Field South surveys, to characterise the AGN in terms of their Eddington ratio and hydrogen column density. Their distributions are then compared with what is predicted when considering the coupling between dust and gas. Our final sample consists of 234 objects from both fields, the largest and deepest sample of AGN for which this comparison has been made up to date. We find that most of the AGN in our sample tend to be found at low Eddington ratios (typically between 1e-4 and 1e-1) and high column density (>1e22 cm^-2), with black hole masses between ~1e8 and 1e9 solar masses. Their distribution is in agreement with that expected from the enhanced radiation pressure model, avoiding the area where we would predict the presence of outflows. We also investigate how the balance between AGN radiation pressure and gravitational potential influences the behaviour of clouds in the galactic bulge, and describe a scenario where an enhanced radiation pressure can lead to the fundamental plane of black hole/galaxy scaling relations.

description: Massive stars form deeply embedded in dense molecular gas, which they stir and heat up and ionize. During an early phase, the ionization is confined to hypercompact HII regions, and the stellar radiation is entirely absorbed by dust, giving rise to a hot molecular core. To investigate the innermost structure of such high-mass star-forming regions, we observed vibrationally excited HCN (via the direct $\ell$-type transition of v2=1, $ΔJ$=0, J=13, which lies 1400 K above ground) toward the massive hot molecular cores G10.47+0.03, SgrB2-N, and SgrB2-M with the Very Large Array (VLA) at 7 mm, reaching a resolution of about 1000 AU (0.1"). We detect the line both in emission and in absorption against HII regions. The latter allows to derive lower limits on the column densities of hot HCN, which are several times $10^{19}$ cm$^{-2}$. We see indication of expansion motions in G10.47+0.03 and detect velocity components in SgrB2-M at 50, 60, and 70 km/s relative to the Local Standard of Rest. The emission originates in regions of less than 0.1 pc diameter around the hypercompact HII regions G10.47+0.03 B1 and SgrB2-N K2, and reaches brightness temperatures of more than 200 K. Using the three-dimensional radiative transfer code RADMC-3D, we model the sources as dense dust cores heated by stars in the HII regions, and derive masses of hot (>300 K) molecular gas of more than 100 solar masses (for an HCN fractional abundance of 10$^{-5}$), challenging current simulations of massive star formation. Heating only by the stars in the HII regions is sufficient to produce such large quantities of hot molecular gas, provided that dust is optically thick to its own radiation, leading to high temperatures through diffusion of radiation.

Nuclear Quadrupole Hyperfine Structure in HC14N/H14NC and DC15N/D15NC Isomerization: A Diagnostic Tool for Characterizing Vibrational Localization

description: Large-amplitude molecular motions which occur during isomerization can cause significant changes in electronic structure. These variations in electronic properties can be used to identify vibrationally-excited eigenstates which are localized along the potential energy surface. This work demonstrates that nuclear quadrupole hyperfine interactions can be used as a diagnostic marker of progress along the isomerization path in both the HC14N/H14NC and DC15N/D15NC chemical systems. Ab initio calculations at the CCSD(T)/cc-pCVQZ level indicate that the hyperfine interaction is extremely sensitive to the chemical bonding of the quadrupolar 14N nucleus and can therefore be used to determine in which potential well the vibrational wavefunction is localized. A natural bonding orbital analysis along the isomerization path further demonstrates that hyperfine interactions arise from the asphericity of the electron density at the quadrupolar nucleus. Using the CCSD(T) potential surface, the quadrupole coupling constants of highly-excited vibrational states are computed from a one-dimensional internal coordinate path Hamiltonian. The excellent agreement between ab initio calculations and recent measurements demonstrates that nuclear quadrupole hyperfine structure can be used as a diagnostic tool for characterizing localized HCN and HNC vibrational states.

description: Для количественного описания любого физического явления необходимо привлекать физические и математические модели. Главным содержанием настоящей статьи является обсуждение некоторых из этих моделей, используемых при преподавании курса общей физики в технических высших учебных заведениях Российской Федерации. Мы также пытаемся установить иерархическую структуру этих моделей. Оказалось, что можно выделить несколько типов моделей: 1) модели первого уровня (базовые модели, которые не требуют для своей формулировки никаких других моделей); 2) двухуровневые модели, которые включают в себя несколько моделей первого уровня; 3) модели третьего уровня, которые обобщают несколько двухуровневых моделей. В качестве моделей первого уровня выделены материальная точка, нерастяжимая невесомая нить, абсолютно твёрдое тело, идеальная сфера, ньютоновская жидкость. В качестве примеров физических явлений, для количественного описания которых необходимы двухуровневые модели, выступают колебания математического, физического и пружинного маятников, колебания стрелки компаса, броуновское движение микрочастиц в жидкости. В качестве примеров моделей третьего уровня рассмотрены гармонический осциллятор и диффузионная модель, опирающаяся на уравнения Ланжевена. Приведены примеры использования моделей третьего уровня для описания физических явлений совершенно различной природы и различной пространственной протяжённости. Знание моделей третьего уровня с ориентацией на будущую специальность/специализацию поможет будущим бакалаврам техники и технологии успешно использовать знания, полученные при изучении курса общей физики. Полученные компетенции пригодятся при изучении специальных дисциплин, а также в их будущей практической деятельности.

description: Let $R$ be a commutative Noetherian ring. We give criteria for flatness of $R$-modules in terms of associated primes and torsion-freeness of certain tensor products. This allows us to develop a criterion for regularity if $R$ has characteristic $p$, or more generally if it has a locally contracting endomorphism. Dualizing, we give criteria for injectivity of $R$-modules in terms of coassociated primes and (h-)divisibility of certain $\Hom$-modules. Along the way, we develop tools to achieve such a dual result. These include a careful analysis of the notions of divisibility and h-divisibility (including a localization result), a theorem on coassociated primes across a $\Hom$-module base change, and a local criterion for injectivity.

description: В статье рассматриваются перспективы использования технологии дополненной реальности в учебном процессе. Перед нами стояла задача повысить мотивацию и интерес к обучению студентов по непрофильной для направления подготовки «Юриспруденция» дисциплине «Информатика». Для достижения указанной цели разработан комплект методических материалов, состоящий из печатных методических рекомендаций и приложения для мобильных устройств на базе операционной системы Android, работа которого описана в данной статье. Идея нашего исследования заключается в создании системы, которая усовершенствует учебный процесс, дополняя печатные методические материалы интеллектуальными функциями и визуальными эффектами. Для разработки приложения для мобильного устройства использовались: среда разработки для мобильных устройств Unity и инструментарий разработчика дополненной реальности Vuforia, языки программирования C# и JavaScript. Описаны преимущества данных сред разработки технологии дополненной реальности для профессорско-преподавательского состава. Для работы системы требуется минимум оборудования: смартфон, поддерживающий операционную систему Android и VR-гарнитура (необязательно). Проведен эксперимент с использованием разработанного комплекта методических материалов, результаты эксперимента описаны в данной статье. Были выявлены недостатки использования технологии дополненной реальности в образовательном процессе, предложены пути их устранения. Также в статье рассмотрена история становления технологии дополненной реальности и ее трансформация из лабораторной технологии в технологию, которая активно внедряется в различные сферы человеческой жизни, в том числе в образование. Сделан вывод, что для повышения мотивации и интереса к обучению, а также повышения качества усваиваемого материала целесообразно использование технологии дополненной реальности в качестве средства обучения.

description: This paper is the second in a series devoted to the hard X-ray (17-60 keV) whole sky survey performed by the INTEGRAL observatory over seven years. Here we present a catalog of detected sources which includes 521 objects, 449 of which exceed a 5 sigma detection threshold on the time-averaged map of the sky, and 53 were detected in various subsamples of exposures. Among the identified sources with known and suspected nature, 262 are Galactic (101 low-mass X-ray binaries, 95 high-mass X-ray binaries, 36 cataclysmic variables, and 30 of other types) and 219 are extragalactic, including 214 active galactic nuclei (AGNs), 4 galaxy clusters, and galaxy ESO 389-G 002. The extragalactic (|b|>5 deg) and Galactic (|b|<5 deg) persistently detected source samples are of high identification completeness (respectively ~96% and ~94%) and valuable for population studies.
