description: We examine 4 years of Kepler 30-min data, and 5 Sectors of TESS 2-min data for the dM3 star KIC 8507979/TIC-272272592. This rapidly rotating (P=1.2 day) star has previously been identified as flare active, with a possible long-term decline in its flare output. Such slow changes in surface magnetic activity are potential indicators of Solar-like activity cycles. We find that KIC 8507979 shows both short and long timescale variations in its flare activity that are larger than expected from the power-law flare occurrence distribution. Only a handful of stars have been subjected to such long baseline point-in-time flare studies. We believe this is powerful new method for measuring the months-to-years changes in surface magnetic activity, and to provide important constraints on activity cycles and dynamo models for low mass stars.

description: One of the important alternative water sources for non-potable purposes is greywater, but needs to remove contaminants. The aim of this study was to investigate the performance of a horizontal series filter (HSF) consists of sand, zeolite (Z), pumice (P), and granular activated carbon (GAC) to analyse the chemical oxygen demand (COD), biochemical oxygen demand (BOD5), total dissolved solids (TDS), turbidity, and pH in greywater samples from Fasa University Student Hostel, Iran. Recycling treatment was performed by passing the greywater through filters. After the last filter, treated greywater was returned into the main tank. The system was run at filtration rate of 2.94 m3 day−1. The analysis of the data from the filtration tests showed that GAC is the best adsorbent for removing COD, BOD5, and TDS from greywater, followed by zeolite. Whereas, pumice is more advisable to remove turbidity. However, due to the different mass of adsorbents in the filters, pumice showed a higher adsorption capacity than zeolite. Generally, the triple combination of GAC+Z + P represented the best performance in the reduction of COD, BOD5, TDS, turbidity up to 90.42%, 91.43%, 82.95%, and 90.27%, respectively. Therefore, the studied system can be implemented in public places to greywater treatment and reuse.
Visualising Oman: An Exploration of National Identity Through Participatory Photography and Printmaking

Publisher: name: Monash University
Year: 2022
Subjects: Visual communication design (incl. graphic design)

description: This research project develops a collaborative and participatory graphic design process through which visual vocabulary associated with Omani identity is considered and reconfigured through an art/design practice. The project is the result of the observation that current visual approaches to national representation of Oman are largely top-down and institutional constructions that reduce visual representation of Oman to a static and traditional iconography. In response, the research provides a methodological framework for reflecting on this inherited visual field and develops new and collaborative works that rethink, challenge, expand and move beyond such received visual vocabulary.

description: The dynamics of the reaction H + OH $\to$ O (3P) + H2 have been studied in a series of quasi-classical trajectory (QCT) calculations and transition state theory (TST) methods using high quality 3A' and 3A'' potential energy surfaces (PESs). Accurate OH (v, j) state resolved cross sections and rate constants on both potential energy surfaces are presented and fitted for OH at (v = 0, j = 0-16) and (v = 1, j = 0-6). The cross sections were calculated for different collisional energies (Ec), ranging from the threshold energy at each specific rovibrational state up to 1.0 eV with step sizes of 0.1 eV or less. They increase steeply with collision energy when the barrier to reaction can be overcome, after which the cross sections stay nearly constant with energy. State resolved rate constants in the temperature range 200-2500 K are presented based on the cross sections. Total thermal rate constants were calculated by summing the rates for reaction on the 3A' and 3A'' potential energy surfaces weighted by 1/3 and taking into account the thermal populations of the rovibrational states of the OH molecules. It is shown that the improved canonical variational transition (CVT) treatments with the approximation of zero-curvature tunneling (ZCT) or small-curvature tunneling (SCT) produce results more in accord with the QCT results than the TST and CVT methods. The reactions are governed by the direct reaction mechanism. The rate constants for OH in excited vibrational and rotational states are orders of magnitude larger than the thermal rate constants, which needs to be taken into account in astrochemical models.

description: Quantum algorithmics with single spins poses serious technological challenges such as precision fabrication, rapid decoherence, atomic-scale addressing and readout. To circumvent atomic-scale challenges, we examine the case of fully polarized mesoscopic spin ensembles (spin-coherent states) whose total angular momenta states map to qudit submanifolds. We show that in the limit where the size of the ensembles is small compared to their separation, it is possible to treat them as qubits with an effective coupling strength that scales with the number of spins. If the spins within each ensemble are decoupled (e.g., via control fields, spinning or diffusional averaging or materials engineering), one- and two-qubit gate operations can be implemented with high fidelities.

description: Some runaway stars are known to display IR arc-like structures around them, resulting from their interaction with surrounding interstellar material. The properties of these features as well as the processes involved in their formation are still poorly understood. We aim at understanding the physical mechanisms that shapes the dust arc observed near the runaway O star AEAur (HD34078). We obtained and analyzed a high spatial resolution map of the CO(1-0) emission that is centered on HD34078, and that combines data from both the IRAM interferometer and 30m single-dish antenna. The line of sight towards HD34078 intersects the outer part of one of the detected globulettes, which accounts for both the properties of diffuse UV light observed in the field and the numerous molecular absorption lines detected in HD34078's spectra, including those from highly excited H2 . Their modeled distance from the star is compatible with the fact that they lie on the 3D paraboloid which fits the arc detected in the 24 μm Spitzer image. Four other compact CO globulettes are detected in the mapped area. These globulettes have a high density and linewidth, and are strongly pressure-confined or transient. The good spatial correlation between the CO globulettes and the IR arc suggests that they result from the interaction of the radiation and wind emitted by HD 34078 with the ambient gas. However, the details of this interaction remain unclear. A wind mass loss rate significantly larger than the value inferred from UV lines is favored by the large IR arc size, but does not easily explain the low velocity of the CO globulettes. The effect of radiation pressure on dust grains also meets several issues in explaining the observations. Further observational and theoretical work is needed to fully elucidate the processes shaping the gas and dust in bow shocks around runaway O stars. (Abridged)

description: It has been critically argued by A. Sfarti [Communications in Physics, Vol.28, No.2 (2018),pp.189-190] that my paper ‘Foundations of Superluminal Relativistic Mechanics’ is wholly incorrect because it is based on a wrong premise. A careful study of the rebuttal reveals however a failure to correctly address the key idea on which my work is based. There is therefore no proof advanced of any alleged incorrectness in my work. Furthermore, the lack of mathematical rigour reinforced with the mathematical errors contained in the aforementioned rebuttal paper has hugely amplified the invalidity of the supposed disproof.

description: With the pervasiveness of digital technologies in human lives, global studies on how people engage with digital technologies have gained momentum, particularly concerning children. However, while extensive studies have been conducted on children’s home digital literacy practices in different contexts, the nature of Iranian children’s home digital literacy practices has not been well examined. Thus, I intend to explore 1) how Iranian children engage with digital texts in English in their homes, 2) the role of parental perspectives and parental mediation strategies in the children’s digital practices, and 3) how these practices combine to foster early English language learning.

description: Hand gesture-based human-computer interaction is an important problem that is well explored using color camera data. In this work we proposed a hand gesture detection system using thermal images. Our system is capable of handling multiple hand regions in a frame and process it fast for real-time applications. Our system performs a series of steps including background subtraction-based hand mask generation, k-means based hand region identification, hand segmentation to remove the forearm region, and a Convolutional Neural Network (CNN) based gesture classification. Our work introduces two novel algorithms, bubble growth and bubble search, for faster hand segmentation. We collected a new thermal image data set with 10 gestures and reported an end-to-end hand gesture recognition accuracy of 97%.

description: This deliverable serves to summarize the semantic representation models that have been developed in the context of WhoLoDancE for organizing the various concepts related to movement, needed for the Learning experiences to be developed during the project. In this document, we mainly focus on the concepts that describe the movement itself.

Section 1 introduces the report and lists its objectives whereas Section 2 refers to the methodology employed and the movement principles defined as its first conclusions. Taking into account the diversity and heterogeneity of dance teaching and learning across genres and contexts, as well as the fact that WhoLoDancE deals with four completely different dance genres, Ballet, Contemporary, Greek Folk, and Flamenco, finding a balance between a generic framework while respecting the characteristics and needs of each dance genre, was a key challenge. Towards this direction, the consortium agreed on focusing on ten basic Movement Principles, which reflect the basic "chapters" of dance teaching or learning objectives to develop sensorimotor skills that are important in all kinds of dance independent of the genre.

Section 3 provides an overview of existing approaches for representing movement in the field of dance whereas Section 4 introduces Wholontology, an ontology which essentially models the description of movement, with focus on dance movement. The primary objective of Wholontology is to provide a knowledge base that can be utilized in various tasks, in the context of the WhoLoDancE project, such as annotation of dance recordings, high-level features extraction, similarity search and searching and browsing the library. Section 4 concludes the paper with the deployment plans for the ontology and its use within the WhoLoDancE framework.

description: We study the dust present in 56 Galactic planetary nebulae (PNe) through their iron depletion factors, their C/O abundance ratios (in 51 objects), and the dust features that appear in their infrared spectra (for 33 objects). Our sample objects have deep optical spectra of good quality, and most of them also have ultraviolet observations. We use these observations to derive the iron abundances and the C/O abundance ratios in a homogeneous way for all the objects. We compile detections of infrared dust features from the literature and we analyze the available Spitzer/IRS spectra. Most of the PNe have C/O ratios below one and show crystalline silicates in their infrared spectra. The PNe with silicates have C/O < 1, with the exception of Cn 1-5. Most of the PNe with dust features related to C-rich environments (SiC or the 30 μm feature usually associated to MgS) have C/O $\gtrsim$ 0.8. PAHs are detected over the full range of C/O values, including 6 objects that also show silicates. Iron abundances are low in all the objects, implying that more than 90% of their iron atoms are deposited into dust grains. The range of iron depletions in the sample covers about two orders of magnitude, and we find that the highest depletion factors are found in C-rich objects with SiC or the 30 μm feature in their infrared spectra, whereas some of the O-rich objects with silicates show the lowest depletion factors.

description: There are many ways to solve the challenging problem of making a high performance robotic observatory from scratch. The Observatorio Astrofísico de Javalambre (OAJ) is a new astronomical facility located at the Sierra de Javalambre (Teruel, Spain) whose primary role will be to conduct all-sky astronomical surveys. The OAJ control system has been designed under a global point of view including not only astronomical subsystems but also infrastructure and other facilities. Three main factors have been considered in the design of a global control system for the robotic OAJ: quality, reliability and efficiency. We propose CIA (Control Integrated Architecture) design and OEE (Overall Equipment Effectiveness) as a key performance indicator in order to improve operation processes, minimizing resources and obtain high cost reduction maintaining quality requirements. The OAJ subsystems considered for the control integrated architecture are the following: two wide-field telescopes and their instrumentation, active optics subsystems, facilities for sky quality monitoring (seeing, extinction, sky background, sky brightness, clouds distribution, meteorological station), domes and several infrastructure facilities such as water supply, glycol water, water treatment plant, air conditioning, compressed air, LN2 plant, illumination, surveillance, access control, fire suppression, electrical generators, electrical distribution, electrical consumption, communication network, Uninterruptible Power Supply and two main control rooms, one at the OAJ and other remotely located in Teruel at 40km from the observatory, connected through a microwave radio-link. Here we present the OAJ strategy in control design to achieve maximum quality efficiency for the observatory processes and operations, giving practical examples of our approach.

description: This document summarizes how we address expressivity in dance practice and teaching, in the framework of WhoLoDancE project. The aim of this document is to define the appropriate models that will be used in the Learning scenarios through an innovative but also meaningful way for dance practitioners for the different dance genres that we investigate: contemporary, ballet, Greek folk and flamenco. For this reason, we present the state-of-the-art in human movement and emotions computing, and we explain the rationale and methodology of our approach. In this context, we consider dance expressivity to be conveyed through qualitative aspects of non-verbal communication and we focus on the analysis of "movement qualities", a term which is widely accepted by both dance practitioners (especially in contemporary dance) but also in movement and gesture computing and Human-computer interaction. This term is used to describe, not the action per se or the shape of the movement, but the way the movement is performed, the dynamics of the movement which make it expressive and meaningful. Though it is true that movement can convey emotions, in none of the dance genres we examine in the context of WhoLoDancE, there exists a one-to-one relationship between emotions and movement, not even Movement Qualities. In addition, though the term “movement qualities” is accepted by both the Dance and Movement Computing communities, they do not include a specific, unique, list of terms that is accepted by all dance practitioners in a universal manner. In this context, part of our work in WhoLoDancE is to define in cooperation with the dance experts (internal and external) an acceptable subset of Movement Qualities that are both meaningful and subject to computation through analysing the multimodal recordings. This document presents the definitions of appropriate emotion models, including associations with music and expressive movement and dance. It also summarizes the outcomes of “T3.1.2 Development of emotion representation models” documenting the definition of the appropriate emotion/movement qualities models for linking, integrating and annotating the multi-modal learning material with high-level emotion-related descriptors. Finally, we explain how we plan to analyse the relationship of these features with the different modalities (music, sound, visual metaphors, different avatars) and how this affects the understanding of Movement Qualities through the Learning Scenarios.

In spite of the fact that the intracavity field is a single-mode field, we take into account the natural multimode structure arising in the field, when it leaves the cavity for the free-space propagation. We show how the purity of the field state can be calculated using the different covariance matrices.

description: Long-duration gamma-ray bursts (GRBs) have been found to be associated with broad-lined type-Ic supernovae (SNe), but only a handful of cases have been studied in detail. Prompted by the discovery of the exceptionally bright, nearby GRB130427A (redshift z=0.3399), we aim at characterising the properties of its associated SN2013cq. This is the first opportunity to test directly the progenitors of high-luminosity GRBs. We monitored the field of the Swift long duration GRB130427A using the 3.6-m TNG and the 8.2-m VLT during the time interval between 3.6 and 51.6 days after the burst. Photometric and spectroscopic observations revealed the presence of the type Ic SN2013cq. Spectroscopic analysis suggests that SN2013cq resembles two previous GRB-SNe, SN1998bw and SN2010bh associated with GRB980425 and XRF100316D, respectively. The bolometric light curve of SN2013cq, which is significantly affected by the host galaxy contribution, is systematically more luminous than that of SN2010bh ($\sim$ 2 mag at peak), but is consistent with SN1998bw. The comparison with the light curve model of another GRB-connected SN2003dh, indicates that SN2013cq is consistent with the model when brightened by 20%. This suggests a synthesised radioactive $^{56}$Ni mass of $\sim 0.4 M_\odot$. GRB130427A/SN2013cq is the first case of low-z GRB-SN connection where the GRB energetics are extreme ($E_{\rm γ, iso} \sim 10^{54}$ erg). We show that the maximum luminosities attained by SNe associated with GRBs span a very narrow range, but those associated with XRFs are significantly less luminous. On the other hand the isotropic energies of the accompanying GRBs span 6 orders of magnitude (10$^{48}$ erg $< E_{\rm γ, iso}

description: The energy demands for the growing development of society need to be catered with alternative and green fuels like hydrogen energy for a lasting and sustainable culture. One essential component of the hydrogen economy is the efficiency of its storage. We have studied the hydrogen-storage capability on a recently synthesized Biphenylene (BPh) decorated with Sc using the first-principles density functional theory (DFT) and ab-initio molecular dynamics (AIMD) techniques. Scandium attaches BPh sheet strongly with binding energy -3.84 eV, and single Sc decorated on BPh can absorb a maximum of five H$_2$ molecules resulting in a high gravimetric weight percentage of 11.07, which is significantly higher than DoE's ultimate criteria (6.5 wt%). Using van't Hoff equation, strongly and weakly attached hydrogens correspond to desorption temperatures of 200 K and 397 K with an average of 305 K. The high binding of Sc to BPh is due to charge donation of 3d orbital of Sc to 2p orbital of C. The interactions between absorbed H$_2$ and BPh+Sc are due to charge transfer from 3d-orbital of Sc to $σ$* bond of H$_2$ molecules and backdonation from $σ$ bond of H$_2$ to empty 3d-orbital of Sc known as Kubas type interaction. Furthermore, phonon and AIMD simulation confirm BPh+Sc stability, and the presence of an energy barrier shows no probability of Sc-Sc clustering on BPh. So theoretically stable BPh+Sc showing high gravimetric weight percentage with an average 305 K desorption temperature, might be a potential candidate for solidstage hydrogen devices.

description: We show, by using direct numerical simulations and theory, how, by increasing the order of dissipativity ($α$) in equations of hydrodynamics, there is a transition from a dissipative to a conservative system. This remarkable result, already conjectured for the asymptotic case $α\to \infty$ [U. Frisch et al., Phys. Rev. Lett. {\bf 101}, 144501 (2008)], is now shown to be true for any large, but finite, value of $α$ greater than a crossover value $α_{\rm crossover}$. We thus provide a self-consistent picture of how dissipative systems, under certain conditions, start behaving like conservative systems and hence elucidate the subtle connection between equilibrium statistical mechanics and out-of-equilibrium turbulent flows.

description: We use the mean-field method, the Quantum Monte-carlo method and the Density matrix renormalization group method to study the trimer superfluid phase and the quantum phase diagram of the Bose-Hubbard model in an optical lattice, with explicit trimer tunneling term. Theoretically, we derive the explicit trimer hopping terms, such as $a_i^{3\dagger}a_j^3$, by the Schrieffer-Wolf transformation. In practice, the trimer super\-fluid described by these terms is driven by photoassociation. The phase transition between the trimer super\-fluid phase and other phases are also studied. Without the on-site interaction, the phase transition between the trimer superfluid phase and the Mott Insulator phase is continuous. Turning on the on-site interaction, the phase transitions are first order with Mott insulators of atom filling $1$ and $2$. With nonzero atom tunneling, the phase transition is first order from the atom superfluid to the trimer superfluid. In the trimer superfluid phase, the win\-ding numbers can be divided by three without any remainders. In the atom superfluid and pair superfluid, the vorticities are $1$ and $1/2$, respectively. However, the vorticity is $1/3$ for the trimer superfluid. The power law decay exponents is $1/2$ for the non diagonal correlation $a_i^{\dagger 3} a_j^{3}$, i.e. the same as the exponent of the correlation $a_i^{\dagger}a_j$ in hardcore bosons. The density dependent atom-tunneling term $n_i^2a_i^{\dagger}a_j$ and pair tunneling term $n_ia_i^{\dagger2}a_j^2$ are also studied. With these terms, the phase transition from the empty phase to atom superfluid is first order and different from the cases without the density dependent terms. The ef\-fects of temperature are studied. Our results will be helpful in realizing the trimer superfluid by a cold atom experiment.

Confinement Potential in a Soft-Wall Holographic Model with a Hydrogen-like Spectrum

description: It is well known that the Soft-Wall holographic model for QCD successfully reproduces not only the linear Regge spectrum, but also, via the holographic Wilson confinement criterion, the ''linear plus Coulomb'' confinement potential similar to the Cornell potential. This property could be interpreted as a holographic counterpart of the hadron string picture, where the linearly rising potential and Regge-like spectrum are directly related. However, such a relation does not take place in the bottom-up holographic approach. Namely, the Cornell-like potentials arise in a broad class of bottom-up holographic models, the standard Soft-Wall model is merely a particular representative of this class. We consider a calculation of confinement potential within a different representative of this class - a Soft-Wall model with linear dilaton background in the metric. This model leads to a Hydrogen like spectrum. The calculation of renormalized potential at short distances turns out to be complicated by a new subtlety that was skipped in general discussions of the issue existing in the literature. But the confinement potential of the model is shown to be not very different from the potential obtained in the standard Soft-Wall model with quadratic background.

description: Since the beginning of aviation, the innovation in technologies and operational procedures have steadily increased comfort, performance and safety of air transport. Especially the latter aspect leads to a continuously decreasing number of fatal accidents despite the steadily increasing number of aeroplanes. In this context, new and more advanced inspection methods for continuous, in-line and repetitive monitoring play a key role. However, the complexity of underlying new technologies must not increase elaborate procedures and maintenance tasks. To bridge the complexity of new technologies and its easy and fruitful application during the daily maintenance of aircraft, close cooperation between the industry as the final user and developing institutes in academia are desirable.
 This presentation examines the collaborative development of three novel aircraft maintenance tools from an industrial point of view. The following concepts, their application and implementation in the daily aircraft maintenance are put into place by means of the close collaboration between Brussels Airlines and the KU Leuven. A retrofit with embedded percolation threshold sensors enables detecting water ingress in the aircraft structure and allows the prediction of hot spots with a high risk of corrosion at an early stage [1]. Acoustic emission measurements enable the detection of melting ice and can potentially increase the efficiency and safety of daily aircraft maintenance [2]. A portable camera system and the usage of digital image correlation allows the fast, digital and remote assessment of impact damages [3]. The research leading to these results has received funding from the “NDTonAIR” project (Training Network in Non-Destructive Testing and Structural Health Monitoring of Aircraft structures) under the action: H2020-MSCA-ITN-2016-GRANT 722134 and from the AISHA II Project (Aircraft Integrated Structural Health Assessment II)under the European Community’s Seventh Framework Programme [FP7/2007-2013] under the grant agreement no. 212912.

description: Novalike cataclysmic variables have persistently high mass transfer rates and prominent steady state accretion disks. We present an analysis of infrared observations of twelve novalikes obtained from the Two Micron All Sky Survey, the Spitzer Space Telescope, and the Wide-field Infrared Survey Explorer All Sky Survey. The presence of an infrared excess at >3-5 microns over the expectation of a theoretical steady state accretion disk is ubiquitous in our sample. The strength of the infrared excess is not correlated with orbital period, but shows a statistically significant correlation (but shallow trend) with system inclination that might be partially (but not completely) linked to the increasing view of the cooler outer accretion disk and disk rim at higher inclinations. We discuss the possible origin of the infrared excess in terms of emission from bremsstrahlung or circumbinary dust, with either mechanism facilitated by the mass outflows (e.g., disk wind/corona, accretion stream overflow, and so on) present in novalikes. Our comparison of the relative advantages and disadvantages of either mechanism for explaining the observations suggests that the situation is rather ambiguous, largely circumstantial, and in need of stricter observational constraints.

Resilient Strong Structural Controllability in Networks using Leaky Forcing in Graphs

description: This paper studies the problem of selecting input nodes (leaders) to make networks strong structurally controllable despite misbehaving nodes and edges. We utilize a graph-based characterization of network strong structural controllability (SSC) in terms of zero forcing in graphs, which is a dynamic coloring of nodes. We consider three types of misbehaving nodes and edges that disrupt the zero forcing process in graphs, thus, deteriorating the network SSC. Then, we examine a leader selection guaranteeing network SSC by ensuring the accuracy of the zero forcing process, despite $k$ misbehaving nodes/edges. Our main result shows that a network is resilient to $k$ misbehaving nodes/edges under one threat model if and only if it is resilient to the same number of failures under the other threat models. Thus, resilience against one threat model implies resilience against the other models. We then discuss the computational aspects of leader selection for resilient SSC and present a numerical evaluation.
Effects of rotation in the energy spectrum of $C_{60}$

description: In this paper, motivated by the experimental evidence of rapidly rotating $C_{60}$ molecules in fullerite, we study the low-energy electronic states of rotating fullerene within a continuum model. In this model, the low-energy spectrum is obtained from an effective Dirac equation including non-Abelian gauge fields that simulate the pentagonal rings of the molecule. Rotation is incorporated into the model by solving the effective Dirac equation in the rotating referential frame. The exact analytical solution for the eigenfunctions and energy spectrum is obtained, yielding the previously known static results in the no rotation limit. Due to the coupling between rotation and total angular momentum, that appears naturally in the rotating frame, the zero modes of static $C_{60}$ are shifted and also suffer a Zeeman splitting whithout the presence of a magnetic field.
