Nonadditive quantum gravitational interaction for three nonpointlike objects

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We explore the nonadditive three-body quantum gravitational quadrupole interaction among three nonpointlike objects in their ground states in the framework of linearized quantum gravity and find that the interaction exhibits a distance behavior of $r_A^{-5}r_B^{-5}r_C^{-5}$ in the near regime where the interobject distances are small compared with the characteristic transition wavelength of the objects, and $r_A^{-5}r_B^{-5}r_C^{-5}(r_A+r_B+r_C)^{-1}$ in the far regime where the distances are larger than the characteristic transition wavelength, where $r_ξ$ denotes the distance between any two objects except object $ξ\;(ξ=A,B,C)$. Compared to the additive quantum gravitational interaction between two ground-state objects in vacuum which is always attractive both in the near and far regimes, the nonadditive interaction among three ground-state objects can be either attractive or repulsive depending on the geometrical configuration of these objects. That is, in principle, the attractive or repulsive properties of the nonadditive three-body quantum gravitational interaction can be manipulated by changing the geometrical arrangement of the objects.

description: We consider the potential dominated era of Friedmann-Lemaitre-Robertson-Walker flat cosmological models in the framework of general Jordan frame scalar-tensor theories of gravity with arbitrary coupling functions, and focus upon the phase space of the scalar field. To study the regime suggested by the local weak field tests (i.e. close to the so-called limit of general relativity) we propose a nonlinear approximation scheme, solve for the phase trajectories, and provide a complete classification of possible phase portraits. We argue that the topology of trajectories in the nonlinear approximation is representative of those of the full system, and thus can tell for which scalar-tensor models general relativity functions as an attractor.

Bifunctional manganese oxide electrodes for reversible oxygen reduction/evolution reactions
Creators: name: Pei, Yu
Publisher: name: University of British Columbia
Year: 2024

description: Efforts to develop cost-efficient, non-precious metal electrodes for reversible oxygen reduction and evolution reactions (ORR/OER) face challenges due to slow kinetics and rapid degradation. To accelerate the development of rechargeable metal-air batteries and regenerative fuel cells, this thesis systematically advances the understanding of nanostructure influence on MnOx electrochemical behaviours and develops innovative approaches for enhancing their stability and activity, positioning the MnOₓ electrodes as promising and sustainable alternatives to precious metal-based electrodes for ORR/OER catalysis. First, this work studies the electrochemical behavior and ORR/OER activity of core-porous shell Mn/Mn₃O₄ nanoparticles in comparison with MnO₂. The core-shell MnOₓ demonstrates higher ORR/OER activities during cycling in O₂-saturated KOH, outperforming exclusive ORR catalysis (influence of potential range) or OER catalysis in a N₂-purged environment (effect of O₂ presence). The unique behaviour of core-shell MnOₓ is attributed to the charge transfer between the low-valent Mn core and the high-valent Mn₃O₄ shell, thereby regenerating Mn(III) active sites through comproportionation. Next, the optimization of gas diffusion electrode (GDE) preparation and conditioning is explored. HNO₃-pretreatment on polytetrafluoroethylene (PTFE)-coated carbon papers was found to reduce overpotentials and eliminate the influence of PTFE loading on voltammograms. The Vulcan XC-72 and graphene mixture showed improved durability by stabilizing Mn sites and restraining Mn₂ oxidation. Lastly, a set of activation protocols was designed to generate and stabilize highly active MnOₓ phases. After cyclic voltammetry conditioning, the MnOₓ/Vulcan/graphene electrode demonstrated extended galvanostatic cyclic stability and a smaller potential gap between the anodic and cathodic reactions. Finally, in-situ electrochemical metallic cation-incorporation on MnOₓ GDE is investigated. In comparison to electrodes prepared through the chronopotentiometry and chronoamperometry approaches, the Co-MnOₓ electrodes prepared using the potentiodynamic method exhibited a significant increase in ORR catalytic current for up to 4.5 times higher and 2.1 times higher at 0.75 VRHE, respectively. Among the explored metal cations, the Ni²⁺ incorporation showed the most significant improvement in terms of activity and cyclic stability. The Ni-MnOₓ GDE demonstrated excellent stability for over 120 cycles in O₂-saturated KOH without losing OER activity, surpassing the Pt/C-IrO₂ benchmark.

description: Many aspects concerning the formation of spiral and disc galaxies remain unresolved, despite their discovery and detailed study over the past $150$ years. As such, we present the results of an observational search for proto-spiral galaxies and their earliest formation, including the discovery of a significant population of spiral-like and clumpy galaxies at $z>1$ in deep \textit{Hubble Space Telescope} CANDELS imaging. We carry out a detailed analysis of this population, characterising their number density evolution, masses, star formation rates and sizes. Overall, we find a surprisingly high overall number density of massive $M_{*} >10^{10}\mathrm{M}_{\odot}$ spiral-like galaxies (including clumpy spirals) at $z > 1$ of $0.18\,{\rm per}\, \mathrm{arcmin}^{-2}$. We measure and characterise the decline in the number of these systems at higher redshift using simulations to correct for redshift effects in identifications, finding that the true fraction of spiral-like galaxies grows at lower redshifts as $\sim$ $(1+z)^{-1.1}$. This is such that the absolute numbers of spirals increases by a factor of $\sim 10$ between $z = 2.5$ and $z = 0.5$. We also demonstrate that these spiral-like systems have large sizes at $z>2$, and high star formation rates, above the main-sequence, These galaxies represent a major mode of galaxy formation in the early universe, perhaps driven by the spiral structure itself. We finally discuss the origin of these systems, including their likely formation through gas accretion and minor mergers, but conclude that major mergers are an unlikely cause.

description: This paper reflects on the issues that were brought to the Roundtable on Hermeneutics and Translocality held at the ZMO in 2006. I review the successive ways in which I have drawn on the hermeneutic philosophical tradition as an anthropologist, emphasing the ethical dimension. Translocality heightens the hermeneutic problem but does not radically change it; it may entail recognizing that everything is always already pretranslated. In reflecting on the task and means of anthropology, I briefly juxtapose Gadamer’s admirable deference or modesty to Ricoeur’s dialectic of appropriation and distanciation and to what Cavell calls the arrogation of voice.

description: We investigate the radio-far infrared (FIR) correlation for a sample of $28$ bright high-redshift ($1 \lesssim z \lesssim 4$) star-forming galaxies selected in the FIR from the Herschel-ATLAS fields as candidates to be strongly gravitationally lensed. The radio information comes either from high sensitivity dedicated ATCA observations at $2.1$ GHz or from cross-matches with the FIRST survey at $1.4$ GHz. By taking advantage of source brightness possibly enhanced by lensing magnification, we identify a weak evolution with redshift out to $z\lesssim 4$ of the FIR-to-radio luminosity ratio $q_{\rm FIR}$. We also find that the $q_{\rm FIR}$ parameter as a function of the radio power $L_{1.4\,\rm GHz}$ displays a clear decreasing trend, similarly to what is observed for optically/radio selected lensed quasars found in literature, yet covering a complementary region in the $q_{\rm FIR}-L_{1.4\,\rm GHz}$ diagram. We interpret such a behavior in the framework of an in-situ galaxy formation scenario, as a result of the transition from an early dust-obscured star-forming phase (mainly pinpointed by our FIR selection) to a late radio-loud quasar phase (preferentially sampled by the optical/radio selection).

description: We present multi-instrument observations of the disc around the Herbig~Ae star, HD~145718, employing geometric and Monte Carlo radiative transfer models to explore the disc orientation, the vertical and radial extent of the near infrared (NIR) scattering surface, and the properties of the dust in the disc surface and sublimation rim. The disc appears inclined at $67-71^{\circ}$, with position angle, PA\,$=-1.0-0.6^{\circ}$, consistent with previous estimates. The NIR scattering surface extends out to $\sim75\,$au and we infer an aspect ratio, $h_{\rm{scat}}(r)/r\sim0.24$ in $J$-band; $\sim0.22$ in $H$-band. Our GPI images and VLTI+CHARA NIR interferometry suggest that the disc surface layers are populated by grains $\gtrsim λ/2π$ in size, indicating these grains are aerodynamically supported against settling and/or the density of smaller grains is relatively low. We demonstrate that our geometric analysis provides a reasonable assessment of the height of the NIR scattering surface at the outer edge of the disc and, if the inclination can be independently constrained, has the potential to probe the flaring exponent of the scattering surface in similarly inclined ($i\gtrsim70^{\circ}$) discs. In re-evaluating HD~145718's stellar properties, we found that the object's dimming events - previously characterised as UX~Or and dipper variability - are consistent with dust occultation by grains larger, on average, than found in the ISM. This occulting dust likely originates close to the inferred dust sublimation radius at $0.17\,$au.

description: TIC137608661/TYC4544-2658-1/FBS0938+788 is a new sdBV+dM reflection-effect binary discovered by the TESS space mission with an orbital period of 7.21 hours. In addition to the orbital frequency and its harmonics, the Fourier transform of TIC137608661 shows many g-mode pulsation frequencies from the sdB star. The amplitude spectrum is particularly simple to interpret as we immediately see several rotational triplets of equally spaced frequencies. The central frequencies of these triplets are equally spaced in period with a mean period spacing of 270.12 s, corresponding to consecutive l=1 modes. From the mean frequency spacing of 1.25 μHz we derive a rotation period of 4.6 days in the deep layers of the sdB star, significantly longer than the orbital period. Among the handful of sdB+dM binaries for which the sdB rotation was measured through asteroseismology, TIC137608661 is the non-synchronized system with both the shortest orbital period and the shortest core rotation period. Only NY Vir has a shorter orbital period but it is synchronized. From a spectroscopic follow-up of TIC137608661 we measure the radial velocities of the sdB star, determine its atmospheric parameters, and estimate the rotation rate at the surface of the star. This measurement allows us to exclude synchronized rotation also in the outer layers and suggests a differential rotation, with the surface rotating faster than the core, as found in few other similar systems. Furthermore, an analysis of the spectral energy distribution of TIC137608661, together with a comparison between sdB pulsation properties and asteroseismic models, gives us further elements to constrain the system.

description: Studying the environments of 0.4 =1.0, which is unable to constrain the halo mass for this sample. However, we find that UVLGs form close (separation < 30 kpc) pairs with the ALL sample, but do not frequently form pairs with LRGs. A rare subset of UVLGs, those with the highest FUV surface brightnesses, are believed to be local analogs of high redshift Lyman Break Galaxies (LBGs) and are called Lyman Break Analogs (LBAs). LBGs and LBAs share similar characteristics (i.e., color, size, surface brightness, specific star formation rates, metallicities, and dust content). Recent HST images of z~0.2 LBAs show disturbed morphologies, signs of mergers and interactions. UVLGs may be influenced by interactions with other galaxies and we discuss this result in terms of other high star-forming, merging systems.

The adoption of inclusive language in abortion related activism
Creators: name: Scofield, Jo
Publisher: name: University of British Columbia
Year: 2024

description: The purpose of this study is to produce accessible knowledge about strategies for implementing gender-inclusive terminology within pro-choice activism in Canada and understand resistance to this implementation. Traditionally, abortion and reproductive healthcare has used ‘woman’ to indicate everyone who can get pregnant, which excludes trans, non-binary, and other gender diverse people who can get pregnant. The shift to inclusive language, as opposed to gendered language, is essential in abortion related activism. Using language such as pregnant person instead of woman is also more accurate as not all women have the capacity to get pregnant, and not all people who get pregnant are women. Neither the need to access abortion care, nor the need to advocate for it, is limited to women. I conducted interviews with people from a variety of abortion related activism groups in Canada to learn about their experience with language changes and what language they use. Changing language used in abortion related activism is an important part of changing language in reproductive healthcare overall. There is significant overlap between the people and resources of activist groups and care providers in reproductive healthcare. This makes implementing inclusive language in all areas of reproductive healthcare and related activism essential to ensuring that everyone who has the capacity for pregnancy can access care in a respectful and affirming environment. My interviews showed that organizations who changed their language to be inclusive saw little to no backlash from transphobic groups or community members. Organizations which began with, and continue to use, inclusive language still encounter difficulty in the gendered nature of many available educational and informational resources. Overall, those most likely to notice the use of inclusive language were trans and non-binary people who were excluded by the use of gendered language in the past. There was no evidence of anyone feeling excluded by the use of inclusive language. This research and the documentation used to conduct it will be made publicly available to help with future work and language changes.

description: Most recently, machine learning has been used to study the dynamics of integrable Hamiltonian systems and the chaotic 3-body problem. In this work, we consider an intermediate case of regular motion in a non-integrable system: the behaviour of objects in the 2:3 mean motion resonance with Neptune. We show that, given initial data from a short 6250 yr numerical integration, the best-trained artificial neural network (ANN) can predict the trajectories of the 2:3 resonators over the subsequent 18750 yr evolution, covering a full libration cycle over the combined time period. By comparing our ANN's prediction of the resonant angle to the outcome of numerical integrations, the former can predict the resonant angle with an accuracy as small as of a few degrees only, while it has the advantage of considerably saving computational time. More specifically, the trained ANN can effectively measure the resonant amplitudes of the 2:3 resonators, and thus provides a fast approach that can identify the resonant candidates. This may be helpful in classifying a huge population of KBOs to be discovered in future surveys.

description: Tidal heating is often used to interpret "radius anomaly" of hot Jupiters (i.e. radii of a large fraction of hot Jupiters are in excess of 1.2 Jupiter radius which cannot be interpreted by the standard theory of planetary evolution). In this paper we find that tidal heating induces another phenomenon "runaway inflation" (i.e. planet inflation becomes unstable and out of control when tidal heating rate is above its critical value). With sufficiently strong tidal heating, luminosity initially increases with inflation, but across its peak it decreases with inflation such that heating is stronger than cooling and runaway inflation occurs. In this mechanism, the opacity near radiative-convective boundary (RCB) scales approximately as temperature to the fourth power and heat cannot efficiently radiate away from planet interior, which induces runaway inflation (similar to a tight lid on a boiling pot). Based on this mechanism, we find that radii of hot Jupiters cannot exceed $2.2R_J$, which is in good agreement with the observations. We also give an upper limit for orbital eccentricity of hot Jupiters. Moreover, by comparison to the observations we infer that tidal heating locates near RCB.
Seismic modeling of a very young SPB star -- KIC8264293

description: KIC8264293 is a fast rotating B-type pulsator observed by Kepler satellite. Its photometric variability is mainly due to pulsations in high-order g modes. Besides, we detected a weak H$α$ emission. Thus, the second source of variability is the fluctuation in a disk around the star. The pulsational spectrum of KIC8264293 reveals a frequency grouping and period spacing pattern. Here, we present the thorough seismic analysis of the star based on these features. Taking into account the position of the star in the HR diagram and fitting the 14 frequencies that form the period spacing we constrain the internal structure of the star. We conclude that the star barely left the ZAMS and the best seismic model has $M = 3.54\,\mathrm{M}_\odot$, $V_\mathrm{rot}=248\,\mathrm{km\,s}^{-1}$ and $Z = 0.0112$. We found the upper limit on the mixing at the edge of the convective core, with the overshooting parameter up to $f_\mathrm{ov} = 0.03$. On the other hand, we were not able to constrain the envelope mixing for the star. To excite the modes in the observed frequency range, we had to modify the opacity data. Our best seismic model with an opacity increase by 100% at the "nickel" bump $\log T=5.46$ explains the whole instability. KIC8264293 is the unique, very young star pulsating in high-order g modes with the Be feature. However, it is not obvious whether the source of this circumstellar matter is the ejection of mass from the underlying star or whether the star has retained its protostellar disk.

Automatic verification of heap-dependent folds in Viper
Creators: name: Tokaeo, Peeranat
Publisher: name: University of British Columbia
Year: 2024

description: Data structures such as lists and arrays are commonly used in real programs to store and manipulate data. To verify such programs, a verification language needs to provide a representation of data structures and tools to reason about them. The Viper verification language enables users to model recursive data structures using predicates and random-access data structures using quantified permissions. While Viper supports heap-dependent functions to express aggregate properties on recursive data structures, it cannot express the same properties for random-access data structures without involving recursion. We introduce a novel technique to support reasoning about aggregate properties on random-access data structures; we call such properties heap-dependent folds. We provide an encoding of this technique using the built-in constructs of Viper, allowing the verifier to prove fold-like properties without recursion or induction. Finally, we implement our design into a Viper plugin. The plugin introduces a new syntax for expressing folds on user-defined data structures and automatically generates relevant axioms to automate proofs.

description: We present precise radiative data of line strengths, transition probabilities and oscillator strengths for the allowed transitions among the $nS_{1/2}$, $nP_{1/2,3/2}$, $n'D_{3/2,5/2}$ and $n'F_{5/2,7/2}$ states with $n=4$ to $6$ and $n'=4,5$ of the Cu-isoelectronic As, Se and Br ions. Due to unavailability of precise observations of these spectroscopic data, their accurate estimations are of great interest and useful in analyzing various astrophysical phenomena undergoing inside the heavenly bodies that contain As, Se and Br elements. An all-order perturbative many-body method in the relativistic theory framework has been employed to determine the atomic wave functions, which are further used to estimate the above quantities with the uncertainties. We found significant differences between some of our results and results that are available earlier.

As part of a Large Chandra Program, new observations were obtained for 52 of these 75 galaxies. The data are complete to a sensitivity of about 10^{39} erg/s, with a typical detection limit of about 3 x 10^{38} erg/s for the majority of the sources. The catalogue contains about 80 ULXs (0.3-10 keV luminosity >10^{39} erg/s), and provides their location, observed flux, de-absorbed luminosity, and (for the 25 most luminous ones) simple X-ray spectral properties. We discuss the ULX luminosity function in relation to the mass and star formation rate of the sample galaxies. We show that recent models of low-mass plus high-mass X-ray binary populations (scaling with stellar mass and star formation rate, respectively) are mostly consistent with our observational results. We tentatively identify the most luminous X-ray source in the sample (a source in IC 3322A with L_{X} ~ 6 x 10^{40} erg/s) as a recent supernova or its young remnant. The properties of the sample galaxies (morphologies, stellar masses, star formation rates, total X-ray luminosities from their point-source population) are also summarised.

description: In supernova remnants, the nonlinear amplification of magnetic fields upstream of collisionless shocks is essential for the acceleration of cosmic rays to the energy of the "knee" at 10^{15.5}eV. A nonresonant instability driven by the cosmic ray current is thought to be responsible for this effect. We perform two-dimensional, particle-in-cell simulations of this instability. We observe an initial growth of circularly polarized non-propagating magnetic waves as predicted in linear theory. It is demonstrated that in some cases the magnetic energy density in the growing waves, can grow to at least 10 times its initial value. We find no evidence of competing modes, nor of significant modification by thermal effects. At late times we observe saturation of the instability in the simulation, but the mechanism responsible is an artefact of the periodic boundary conditions and has no counterpart in the supernova-shock scenario.

description: The final stage of gas giant formation involves accreting gas from the parent protoplanetary disk. In general, the infalling gas likely approaches a free-fall velocity, creating an accretion shock, leading to strong shock heating and radiation. We investigate the kinematics and energetics of such accretion shocks using 1D radiation hydrodynamic simulations. Our simulations feature the first self-consistent treatment of hydrogen dissociation and ionization, radiation transport, and realistic grey opacity. By exploring a broad range of giant planet masses (0.1-3 M$_{J}$) and accretion rates ($10^{-3}$-$10^{-2}$M$_{\oplus}\cdot\rm{yr}^{-1}$), we focus on global shock efficiency and the final entropy of the accreted gas. We find that radiation from the accretion shock can fully disassociate the molecular hydrogen of the incoming gas when the shock luminosity is above a critical luminosity. Meanwhile, the post-shock entropy generally fall into "cold" ($<12k_{\rm{B}}/m_{\rm H}$) and "hot" ($>16k_{\rm{B}}/m_{\rm H}$) groups which depends on the extent of the endothermic process of $\rm{H}_2$ dissociation. While 2D or 3D simulations are needed for more realistic understandings of the accretion process, this distinction likely carries over and sheds light on the interpretation of young direct imaging planets.

Detecting intermediate mass black holes in midiquasars with current and future surveys

description: The lack of detected intermediate mass black holes poses a gap in our understanding of the growth and evolution of the most exotic of astrophysical objects. Here we investigate the possibility of low-luminosity relativistic jets launched by intermediate mass black holes in the centers of dwarf galaxies. We built population models that allow us to make predictions for their radio emission and quantify their detectability by current and future surveys. We find that the upcoming instruments in optical and radio like the SKA, ngVLA and the Vera C. Rubin Observatory will likely be able to detect a significant fraction ($>38\%$) of such sources population if they exist. In addition, our results suggest that it is not unlikely a small number of midiquasars possibly masquerading as low-luminosity active galactic nuclei may have already been detected by existing surveys.

description: Situations of a functional predictor paired with a scalar response are increasingly encountered in data analysis. Predictors are often appropriately modeled as square integrable smooth random functions. Imposing minimal assumptions on the nature of the functional relationship, we aim to estimate the directional derivatives and gradients of the response with respect to the predictor functions. In statistical applications and data analysis, functional derivatives provide a quantitative measure of the often intricate relationship between changes in predictor trajectories and those in scalar responses. This approach provides a natural extension of classical gradient fields in vector space and provides directions of steepest descent. We suggest a kernel-based method for the nonparametric estimation of functional derivatives that utilizes the decomposition of the random predictor functions into their eigenfunctions. These eigenfunctions define a canonical set of directions into which the gradient field is expanded. The proposed method is shown to lead to asymptotically consistent estimates of functional derivatives and is illustrated in an application to growth curves.

description: 21cm tomography opens a window to directly study astrophysics and fundamental physics of early epochs in our Universe's history, the Epoch of Reionisation (EoR) and Cosmic Dawn (CD). Summary statistics such as the power spectrum omit information encoded in this signal due to its highly non-Gaussian nature. Here we adopt a network-based approach for direct inference of CD and EoR astrophysics jointly with fundamental physics from 21cm tomography. We showcase a warm dark matter (WDM) universe, where dark matter density parameter $Ω_\mathrm{m}$ and WDM mass $m_\mathrm{WDM}$ strongly influence both CD and EoR. Reflecting the three-dimensional nature of 21cm light-cones, we present a new, albeit simple, 3D convolutional neural network for efficient parameter recovery at moderate training cost. On simulations we observe high-fidelity parameter recovery for CD and EoR astrophysics ($R^2>0.78-0.99$), together with DM density $Ω_\mathrm{m}$ ($R^2>0.97$) and WDM mass ($R^2>0.61$, significantly better for $m_\mathrm{WDM}<3-4\,$keV). For realistic mock observed light-cones that include noise and foreground levels expected for the Square Kilometre Array, we note that in an optimistic foreground scenario parameter recovery is unaffected, while for moderate, less optimistic foreground levels (occupying the so-called wedge) the recovery of the WDM mass deteriorates, while other parameters remain robust against increased foreground levels at $R^2>0.9$. We further test the robustness of our network-based inference against modelling uncertainties and systematics by transfer learning between bare simulations and mock observations; we find robust recovery of specific X-ray luminosity and ionising efficiency, while DM density and WDM mass come with increased bias and scatter.

description: We present data from Integral Field Spectroscopy for 3 supercompact UV-Luminous Galaxies (ScUVLGs). As nearby (z~0.2), compact (R_50~1-2 kpc), bright Paschen-alpha sources, with unusually high star formation rates (SFR=3-100 M_sun/yr), ScUVLGs are an ideal population for studying detailed kinematics and dynamics in actively star-forming galaxies. In addition, ScUVLGs appear to be excellent analogs to high redshift Lyman Break Galaxies (LBGs) and our results may offer additional insight into the dynamics of LBGs. Previous work by our team has shown that the morphologies of these galaxies exhibit tidal features and companions, and in this study we find that the dynamics of ScUVLGs are dominated by disturbed kinematics of the emission line gas-- suggestive that these galaxies have undergone recent feedback, interactions or mergers. While 2 of the 3 galaxies do display rotation, v/sigma < 1 -- suggesting dispersion dominated kinematics rather than smooth rotation. We also simulate how these observations would appear at z~2. Lower resolution and loss of low surface brightness features causes some apparent discrepancies between the low-z (observed) and high-z (simulated) interpretations and quantitatively gives different values for v/sigma, yet simulations of these low-z analogs manage to detect the brightest regions well and resemble actual high-z observations of LBGs.

description: For a finite dimensional Lie algebra $L$, it is known that $s(L)=\f{1}{2}(n-1)(n-2)+1-\mathrm{dim} M(L)$ is non negative. Moreover, the structure of all finite nilpotent Lie algebras is characterized when $s(L)=0,1$ in \cite{ni,ni4}. In this paper, we intend to characterize all nilpotent Lie algebra while $s(L)=2.$

description: Der vorliegende Beitrag liefert ein Konzept für eine evidenzbasierte, automatisierte Online-Pilotenzustandserfassung als Grundlage für ein Workload-adaptives Assistenzsystem für bemannt-unbemannte Hubschraubermissionen. Die Basis für die Pilotenzustandserfassung bildet ein normatives Pilotenmodell, das die Aufgaben und die dafür notwendigen mentalen Ressourcen der Hubschrauber-besatzung abbildet. Mittels verschiedener Methoden zur Operateurbeobachtung, wie semantischer Blickbewegungsmessung, Interaktionsbeobachtung und Kommunikationserfassung, werden Evidenzen generiert, die auf die Durchführung bestimmter Pilotenaufgaben hinweisen. Ein Inferenzalgorithmus auf Grundlage einer vereinfachten Form der Evidenztheorie von Dempster- und Shafer kombiniert diese Evidenzen und erlaubt das Schließen auf die aktuellen Tätigkeiten der Besatzung im Cockpit. Das hier vorgestellte Konzept wird als Funktionsprototyp realisiert und in einem Hubschraubersimulator integriert.

description: In this work, SBA-15 mesoporous silica has been chemically functionalized with guanidin groups. The resulting material has been characterised and employed as solid phase extractant for preconcentration of Pb2+, Cu2+, Zn2+ and Cd2+ ions. The ions were identified by flame atomic absorption spectrometry (FAAS). The enrichment factor of the proposed method was 100 and detection limits were found to be 4.5, 0.6, 0.2 and 0.5 ng mL−1 for Pb2+, Cu2+, Zn2+ and Cd2+ respectively. The time and the optimum amount of the sorbent, pH and minimum amount of acid for stripping and break through volume were investigated. The maximum capacity the adsorbent was found to be 89.1 (±1.7) μg, 57.2 (±1.6) μg, 26.8 (±1.6) μg and 36.0 (±0.6) μg of Pb2+, Cu2+, Zn2+ and Cd2+ per mg functionalized SBA-15, respectively.
