subject: Networking and communications

description: With the development of computing and communication technology, networked systems in which information is exchanged through communication networks have become prevalent in a variety of practical applications. A considerable number of these systems have scarcely adequate computation and communication network resources. Notice that, network dynamics usually affect the quality of the performance of networked systems; network-based control or filtering design generally interferes with the quality of service of communication networks. Therefore, successful implementation of networked systems over communication networks requires the adequate integration of control or filtering with intelligent computation and communication networks. This research establishes an information scheduling middleware to effi- ciently utilise the limited communication resources and the computation capacity while preserving the desired performance of networked systems. In this proposed middleware, an event-triggered scheme is given to provide a tradeoff between the performance of networked systems and the utilisation of communication network resources. A scheduling mechanism is derived to avoid traffic congestion in the communication network by introducing a fluid-flow model. By using this information scheduling middleware, the issues of network-based control and filtering are investigated. First, a fluid-flow model of the communication network and an eventtriggered scheme are integrated to develop a new framework, in which the criteria of stability and stabilisation are derived for networked systems under simultaneous consideration of control system performance and network dynamics. Second, based on network dynamics, an online scheduling strategy is proposed to design the H∞ filter for networked systems in the framework with the information scheduling middleware, the Information Dispatching Middleware (IDM). Third, the IDM is applied to distributed control for large-scale networked systems and a codesign method is obtained to determine the parameters of the IDM. Fourth, the mechanism of the IDM is analysed to investigate the cooperation between the Information Selection Module and the Congestion Avoidance Module in the IDM. Based on the IDM, distributed filters are designed considering the dynamics of communication networks. Finally, numerical and practical examples are given to demonstrate the effectiveness and advantages of the proposed information scheduling middleware.

description: We prove that the complement of any affine 2-arrangement in R^d is minimal, that is, it is homotopy equivalent to a cell complex with as many i-cells as its i-th rational Betti number. For the proof, we provide a Lefschetz-type hyperplane theorem for complements of 2-arrangements, and introduce Alexander duality for combinatorial Morse functions. Our results greatly generalize previous work by Falk, Dimca--Papadima, Hattori, Randell, and Salvetti--Settepanella and others, and they demonstrate that in contrast to previous investigations, a purely combinatorial approach suffices to show minimality and the Lefschetz Hyperplane Theorem for complements of complex hyperplane arrangements.

description: Advanced oxidation processes have gained colossal attention owing to the prospect of accessible mineralization, but by-product formation and its toxicity evaluation are still inconclusive. The present study demonstrated the performance of electrochemical oxidation process supported with graphite electrodes for the oxidation of phenol from modulated coke oven wastewater. The results suggested that the hydrogen peroxide along with the in-situ synthesized oxidizing agents has the ability to increase the phenol mineralization 1.5 times and by-product toxicity potential on microalgae, Scenedesmus sp. CBIIT(ISM) also revealed that chlorophyll-a synthesis has increased after the electro-oxidation process in coke oven wastewater. The experimental results for phenol mineralization and by-product formation were validated using a mass spectrophotometer.

description: This paper investigates the fate of natural organic matter (NOM) during the full-scale drinking water treatment plant supplied by Danube river bank filtration. After the recent reconstruction of the plant, special attention was devoted to the effects of ozone dose and granulated activated carbon (GAC) filtration on the formation and behaviour of oxidation by-products (carbonyl compounds and bromate), as well as carbonaceous and nitrogenous chlorination by-products. For the oxidation of aromatic NOM moieties that absorb light at UV254, a lower ozone dose (1.0 g O3/m3) is sufficient, whereas to achieve a measurable reduction (about 20%) of total organic carbon, an ozone dose of 1.5 g O3/m3 is required. The content of carbonyl compounds in the water after ozonation increases relative to the content before oxidation treatment, and is up to 12 times higher in the case of aldehydes and up to 2 times higher in the case of carboxylic acids. Seasonal variations, including changes in temperature and the amount of precipitation, were also shown to affect the content of organic matter in the raw water, with slight effects on the quality of the treated water. In the winter, the organic matter content is slightly higher, meaning their transformation products aldehydes and carboxylic acids, are also higher during the winter than the summer.

description: Many correlated materials display a quantum critical point between a paramagnetic and a SDW state. The SDW wave vector connects points (hot spots) on opposite sides of the Fermi surface. The Fermi velocities at these pairs of points are in general not parallel. Here we consider the case where pairs of hot spots coalesce, and the wave vector (π,π) of the SDW connects hot spots with parallel Fermi velocities. Using the specific example of electron-doped cuprates, we first show that Kanamori screening and generic features of the Lindhard function make this case experimentally relevant. The temperature dependence of the correlation length, the spin susceptibility and the self-energy at the hot spots are found using the Two-Particle-Self-Consistent theory and specific numerical examples worked out for parameters characteristic of the electron-doped cuprates. While the curvature of the Fermi surface at the hot spots leads to deviations from perfect nesting, the pseudo-nesting conditions lead to drastic modifications to the temperature dependence of these physical observables: Neglecting logarithmic corrections, the correlation length ξscales like 1/T, i.e. z=1 instead of the naive z=2, the (π,π) static spin susceptibility χlike $1/\sqrt T$, and the imaginary part of the self-energy at the hot spots like $T^{3/2}$. The correction $T_1^{-1}\sim T^{3/2}$ to the Korringa NMR relaxation rate is subdominant. We also consider this problem at zero temperature, or for frequencies larger than temperature, using a field-theoretical model of gapless SDW fluctuations interacting with fermions. The imaginary part of the fermionic self-energy close to the hot spots scales as $-ω^{3/2}\logω$. This is less singular than earlier predictions of the form $-ω\logω$. The difference arises from the effects of umklapp terms that were not included in previous studies.

description: Este proyecto tiene como objeto desarrollar un recurso educativo digital basado en la gamificación para fortalecer la didáctica en los maestros en formación de la Escuela Normal Superior de la Mojana con el fin de responder a la problemática relacionada con la falta de integración de las TIC reflejada alrededor del ejercicio de las prácticas pedagógicas, específicamente, en la didáctica utilizada por los maestros en formación en sus planeaciones e intervenciones que pone en evidencia la práctica de métodos y recursos tradicionales en la orientación de clases. Los resultados obtenidos evidenciaron que la mayoría de los maestros en formación no tenían un buen nivel de conocimiento sobre los recursos educativos digitales basados en la gamificación y no existía una articulación entre la didáctica y el uso de recursos educativos digitales en la práctica pedagógica de los maestros en formación. Por lo que se diseñó el RED basado en la gamificación DidacGame usando diversas aplicaciones digitales. Luego, se implementó en una prueba piloto y después se evaluó reflejando un 94% de calidad en su diseño. Para concluir, el RED DidacGame resultó ser una estrategia efectiva para motivar y aumentar el compromiso de los maestros para innovar didácticamente a partir de la gamificación.

description: In a suitably chosen back-to-back kinematics, four-jet production in hadronic collisions is known to be dominated by contributions from two independent partonic scattering processes, thus giving experimental access to the structure of generalized two-parton distributions 2GPDs. Here, we show that a combined measurement of the double hard four-jet cross section in proton-proton and proton-nucleus collisions will allow one to disentangle different sources of two-parton correlations in the proton, that cannot be disentangled with 4-jet measurements in proton-proton collisions alone. To this end, we analyze in detail the structure of 2GPDs in the nucleus (A), we calculate in the independent nucleon approximation all contributions to the double hard four-jet cross section in pA, and we determine corrections arising from the nuclear dependence of single parton distribution functions. We then outline an experimental strategy for determining the longitudinal two-parton correlations in the proton.

description: We study the time evolution of spherical, excited -- with $n$ radial nodes -- scalar boson stars in General Relativity minimally coupled to a complex massive scalar field with quartic self-interactions. We report that these stars, with up to $n=10$, can be made dynamically stable, up to timescales of $t\sim\frac{10^{4}}{cμ}$, where $μ$ is the inverse Compton wavelength of the scalar particle, for sufficiently large values of the self-interactions coupling constant $λ$, which depend on $n$. We observe that the compactness of these solutions is rather insensitive to $n$, for large $λ$ and fixed frequency. Generically, along the branches where stability was studied, these excited boson stars are not compact enough to allow for innermost stable circular orbits or light rings. Finally, we discuss the angular velocity of particles along timelike circular orbits, suggesting an application, for solutions in the Newtonian limit, to galactic rotation curves.

description: This paper demonstrates modelling of the aerobic granular sludge (AGS) process with the pseudo-analytical solutions (PAS) of a biofilm model. A MATLAB programmed graphical user interface platform was developed to facilitate the model calculation and access. Model calibration and validation were carried out through using experimental data collected from a granular sludge sequencing batch reactor operation. The experimental and modelling results identified the distribution of heterotrophs and nitrifiers on the AGS and its contribution to the performance of wastewater treatment. The model could describe multi-species biofilms according to the distinguishing features among the three levels of PAS models. The models demonstrated increasing degrees of interaction (no interaction, competition for nitrogen and layering and protection) between heterotrophs and nitrifiers. Modelling the AGS process using PAS increases the accessibility of the simulation of multiple species in both biofilm and suspended biomass.

Η έρευνα επικεντρώθηκε τόσο στην επιρροή ΄των μέσων κοινωνικής δικτύωσης, από την πλευρά των τουριστικών επιχειρήσεων, όσο και στην επιρροή που δέχονται οι ίδιοι οι τουρίστες. Το παρακάτω περιεχόμενο, περιλαμβάνει βιβλιογραφικές αναφορές, οι οποίες επικεντρώνονται στην αποσαφήνιση πολλών υποθέσεων γύρω από το εξεταζόμενο θέμα, ενώ ταυτόχρονα η εκτέλεση των δύο ερωτηματολογίων που πραγματοποιηθήκαν κατά τη διάρκεια εκπόνησης, συμπληρώνουν τη θεωρία και διαμορφώνουν τα τελικά αποτελέσματα και συμπεράσματα. Είναι αναμφίβολο, ότι η βιομηχανία του τουρισμού, αποτελεί τη ναυαρχίδα της ελληνικής οικονομίας, ενώ τα μέσα κοινωνικής δικτύωσης, επηρεάζουν τον κλάδο, τοποθετώντας το στο σύγχρονο περιβάλλον της ψηφιακής εποχής του 21ου αιώνα, αναγεννώντας όλα τα οφέλη που προκύπτουν από τη χρήση αυτών, καθώς και τις δυνατότητες που παρέχονται και που προσφέρονται σε όποιον αποφασίσει να τα χρησιμοποιήσει σαν ένα ισχυρό εργαλείο, είτε από την πλευρά του καταναλωτή, είτε από την πλευρά των επιχειρήσεων. Σύμφωνα με την παρακάτω έρευνα, τα μέσα κοινωνικής δικτύωσης προσφέρουν μία πληθώρα πλεονεκτημάτων στον κλάδο του τουρισμού, ενισχύοντας προορισμούς και επιχειρήσεις που δραστηριοποιούνται στον κλάδο. Επιπλέον, η συμβολή τους είναι μεγάλη και σημαντική και για τους ίδιους τους τουρίστες, οι οποίοι χρησιμοποιώντας τα social media σε όλα τα στάδια ενός ταξιδιού, έχουν επωφεληθεί με αποτέλεσμα τον καλύτερο προγραμματισμό και σχεδιασμό των ταξιδιών τους, την καλύτερη και πιο έγκυρη πληροφόρηση τους σχετικά με έναν προορισμό, καθώς επίσης και τη διευκόλυνση ανατροφοδότησης και διαμοιρασμού των εμπειριών και των συναισθημάτων που βίωσαν με οικεία ή μη διαδικτυακά πρόσωπα, στα μέσα κοινωνικής δικτύωσης που έχουν λογαριασμό και τα χρησιμοποιούν ενεργά. Στο σύγχρονο κόσμο, με τον τουρισμό να εξελίσσεται ολοένα και περισσότερο, τα μέσα κοινωνικής δικτύωσης ασκούν μεγάλη επίδραση στον κλάδο αυτό, με την ελληνική τουριστική βιομηχανία να αναδιαμορφώνεται μέσα από τη χρήση των διαδικτυακών εργαλείων και τους τουρίστες να αναπτύσσουν μια διαφορετική τουριστική συμπεριφορά, συγκριτικά με παλαιότερα, εμφανώς αλλαγμένη, λόγω των social media.

description: Physical inactivity is an important public health issue which impacts on many facets of health at an individual level and within a workplace. The Queensland based, 10,000 Steps Workplace Challenge has been widely adopted, but its effectiveness within an office workplace has not been formally evaluated. The purpose of this study was to assess the effectiveness of the 10,000 Steps Workplace Challenge to increase physical activity. A 6-week team-based, intervention that required team-members to record their daily steps on the 10,000 Steps website. Participants (n = 141) were randomised into an Immediate Start group or a Delayed Start group (which only gained access to the intervention after 6-weeks). Physical activity was measured using the Active Australia Survey at baseline, 6-, 12- and 36-weeks. Generalised linear mixed models were used to analyse the data. It was established that there was no difference between the groups at 6-weeks (OR = 0.89, 95% CI = 0.49-1.60, p = 0.889). However, within the Immediate Start group, compared to baseline the proportion of participants achieving sufficient physical activity increased at 6-weeks (OR = 2.20, 95% CI = 1.25-3.86, p = 0.007) and 36-weeks (OR = 1.92, 95% CI = 1.05-3.50, p = 0.035), but not at 12-weeks (OR = 1.57, 95% CI = 0.90-2.74, p = 0.113). The 10,000 Steps Workplace Challenge demonstrated that physical activity increased within the Immediate Start group. However, due to physical activity increases in the Delayed Start group prior to the commencement of the intervention, it is not possible to determine if this increase was due to the intervention or other factors.

description: This study proposes an approach toward the first principles electronic structure calculation with the aid of symbolic-numeric solving. The symbolic computation enables us to express the Hartree-Fock-Roothaan equation and the molecular integrals in analytic forms and approximate them as a set of polynomial equations. By use of the Grobner bases technique, the polynomial equations are transformed into other ones which have identical roots. The converted equations take more convenient forms which will simplify numerical procedures, from which we can derive necessary physical properties in order, in an a la carte way. This method enables us to solve the electronic structure calculation, the optimization of any kind, or the inverse problem as a forward problem in a unified way, in which there is no need for iterative self-consistent procedures with trials and errors.

description: Device independent dimension witnesses provide a lower bound on the dimensionality of classical and quantum systems in a "black box" scenario where only correlations between preparations, measurements and outcomes are considered. We address the problem of the robustness of dimension witnesses, namely that to witness the dimension of a system or to discriminate between its quantum or classical nature, even in the presence of loss. We consider the case when shared randomness is allowed between preparations and measurements and we provide a threshold in the detection efficiency such that dimension witnessing can still be performed.

description: We consider the problem of jamming attack in a multiple access channel with training-based transmission. First, we derive upper and lower bounds on the maximum achievable ergodic sum-rate which explicitly shows the impact of jamming during both the training phase and the data transmission phase. Then, from the jammer's design perspective, we analytically find the optimal jamming energy allocation between the two phases that minimizes the derived bounds on the ergodic sum-rate. Numerical results demonstrate that the obtained optimal jamming design reduces the ergodic sum-rate of the legitimate users considerably in comparison to fixed power jamming.

description: The measurements of the Higgs boson and top quark masses can be used to extrapolate the Standard Model Higgs potential at energies up to the Planck scale. Adopting a NNLO renormalization procedure, we: i) find that electroweak vacuum stability is at present allowed, discuss the associated theoretical and experimental errors and the prospects for its future tests; ii) determine the boundary conditions allowing for the existence of a shallow false minimum slightly below the Planck scale, which is a stable configuration that might have been relevant for primordial inflation; iii) derive a conservative upper bound on type I seesaw right-handed neutrino masses, following from the requirement of electroweak vacuum stability.

An examination of ground cover for the assessment of ecosystem condition in the silver-leaved ironbark woodlands of the Desert Uplands
Creators: name: McCosker, Juliana

Subjects: classificationCode: 310308
subject: Terrestrial ecology

description: The thesis examines the ecosystem condition of silver-leaved ironbark woodlands within a spatial and temporal context. This relatively homogenous ecosystem, which covers over one million hectares within the Desert Uplands bioregion in Central Queensland, provides the ideal environment in which to examine relationships of condition variables across scales from site to landscape. The results establish that links exist between grazing pressures on ground cover and a number of ecosystem condition variables. The remotely sensed Ground Cover Index (GCI) was found to have significant relationships with field measurements. The current ecosystem condition assessment method using the Ground Cover Disturbance Index (derived from the GCI) is assessed and improvements are suggested that allow climatic effects to be accounted for to ensure the index better reflects ecosystem functionality. The GCI, together with field ground cover measurements are explored to assess ecosystem condition with respect to field measurements of avian and plant diversity. The GCI was found to have a significant relationship with perennial grass cover. Perennial grass abundance and richness were found to have significant relationships with ground cover and are recommended as indicators of ecosystem condition. Avian groups as indicators were less effective with both strong positive and negative relationships with ground cover existing within the groups. The bird habitat assemblage group shows promise for further investigation for the assessment of ecosystem condition. Finally, linear mixed effect modelling established the relationship between ground cover and climate and grazing explanatory variables; the effects of each variable were qualified and the predictive power of the model was validated against ground cover measurements.
Zigzag edge states in graphene in the presence of in-plane electric field

description: The present study explores the edge states in a finite-width graphene ribbon and a semi-infinite geometry subject to a perpendicular magnetic field and an in-plane electric field, applied perpendicular to a zigzag edge. To accomplish this, a combination of analytic and numerical methods within the framework of low-energy effective theory is employed. Both the gapless and gapped Dirac fermions in graphene are considered. It is found that a surface mode localized at the zigzag edge remains dispersionless even in the presence of electric field. This is shown analytically by employing Darwin's expansion of the parabolic cylinder functions of large order and argument.

Conceptualising disability from a Samoan epistemological and cultural reference frame
Creators: name: Picton, Catherine
Publisher: name: CQUniversity
Year: 2023
Subjects: classificationCode: 451399
subject: Pacific Peoples culture, language and history not elsewhere classified

description: This research is concerned with the changing conceptualisations of disability in Samoa. The research also investigates fundamental cultural belief systems and contemporary ideologies that affect people with disability in Samoan society. Samoan policy reform within the area of disability has provided an alternate paradigm for society to view disability. Stakeholder groups have largely embraced recent policy reforms, endorsing a social disability model. However, due to a history of missionary involvement, colonisation and traditional cultural ideologies Samoa already has several conceptualisations of disability that challenge the philosophy of a social disability model.

description: Synopsis: The goal of this collective monograph is to explore the relationship between the cognitive notion of number and various grammatical devices expressing this concept in natural language with a special focus on Slavic. The book aims at investigating different morphosyntactic and semantic categories including plurality and number-marking, individuation and countability, cumulativity, distributivity and collectivity, numerals, numeral modifiers and classifiers, as well as other quantifiers. It gathers 19 contributions tackling the main themes from different theoretical and methodological perspectives in order to contribute to our understanding of cross-linguistic patterns both in Slavic and non-Slavic languages.

Effects of soil health management practices on plant root development
Creators: name: Pandey, Sushil
Publisher: name: CQUniversity
Year: 2023
Subjects: classificationCode: 300802
subject: Horticultural crop growth and development

description: The plant root system is the connection between the aboveground biomass and the soil system, and it requires a healthy soil environment to support optimum root growth. A healthy and extensive root system allows the plant to explore a greater soil volume for water and nutrients, and thereby increase the likelihood of more productive crop.Intensive vegetable production systems with little or no organic materials incorporated into soil combined with heavy farm traffic and use of chemical fertilizers often lead to detrimental impacts on soil health characteristics, reducing capacity to support extensive root system development. Crops in these systems may also be more susceptible to high incidence and severity of soil-borne root diseases, which further reduces the root system and yield capacity of the crop. Pathogen damage to crop root systems is a major threat to crop production, and while current management systems can mitigate against this threat, alternative strategies based on building soil health through building soil organic carbon content and strong plant root systems is more sustainable. This research investigated the effects of different organic materials to soil microbial communities, plant root system development and crop performance in cropping soils.
Crystalline Undulator with a Small Amplitude and a Short Period

description: The crystalline undulator is a single crystal with periodically bent crystallographic planes. If ultrarelativistic charged particles channel through such a crystal, they emit hard radiation of undulator type. A crystalline undulator with a bending amplitude smaller than the distance between the bent planes and a bending period shorter than the period of channeling oscillations is proposed. Heretofore, it was believed that such a range of bending parameters was unsuitable for a crystalline undulator. This point of view is refuted. In fact, the undulator with a small amplitude and a short period is far superior to what was proposed previously. It requires much lower beam energy for production of photons of the same frequency. Such an undulator allows for a larger effective number of undulator periods. It is predicted to emit intense undulator radiation in the forward direction with a narrow spectral distribution and a lower and softer background. The undulator effect is seen for both positron and electron beams. Using positrons is, however, preferable because they enable one to obtain higher intensity of the undulator radiation with lower background.

description: We present a detailed period analysis of the bright Cepheid-type variable star V1154 Cygni (V =9.1 mag, P~4.9 d) based on almost 600 days of continuous observations by the Kepler space telescope. The data reveal significant cycle-to-cycle fluctuations in the pulsation period, indicating that classical Cepheids may not be as accurate astrophysical clocks as commonly believed: regardless of the specific points used to determine the O-C values, the cycle lengths show a scatter of 0.015-0.02 days over the 120 cycles covered by the observations. A very slight correlation between the individual Fourier parameters and the O-C values was found, suggesting that the O - C variations might be due to the instability of the light curve shape. Random fluctuation tests revealed a linear trend up to a cycle difference 15, but for long term, the period remains around the mean value. We compare the measurements with simulated light curves that were constructed to mimic V1154 Cyg as a perfect pulsator modulated only by the light travel time effect caused by low-mass companions. We show that the observed period jitter in V1154 Cyg represents a serious limitation in the search for binary companions. While the Kepler data are accurate enough to allow the detection of planetary bodies in close orbits around a Cepheid, the astrophysical noise can easily hide the signal of the light-time effect.

description: 1$T$-TaSe$_2$ is widely believed to host a Mott metal-insulator transition in the charge density wave (CDW) phase according to the spectroscopic observation of a band gap that extends across all momentum space. Previous investigations inferred that the occurrence of the Mott phase is limited to the surface only of bulk specimens, but recent analysis on thin samples revealed that the Mott-like behavior, observed in the monolayer, is rapidly suppressed with increasing thickness. Here, we report combined time- and angle-resolved photoemission spectroscopy and theoretical investigations of the electronic structure of 1$T$-TaSe$_2$. Our experimental results confirm the existence of a state above $E_F$, previously ascribed to the upper Hubbard band, and an overall band gap of $\sim 0.7$ eV at $\overlineΓ$. However, supported by density functional theory calculations, we demonstrate that the origin of this state and the gap rests on band structure modifications induced by the CDW phase alone, without the need for Mott correlation effects.
