description: Recent increased of interest in the development of high-performance buildings is strongly related to
the world-wide efforts to reduce greenhouse gas emissions and energy costs. One of the principal goals is to develop
the integration of solar devices (photovoltaic components and thermal collectors) in the building envelope. However,
available buildings envelop surfaces with suitable orientation are not so important at a building scale for energy supply.
They have to be valorized and optimized. This is for this reason why this work is dedicated to the optimization
of multi-energy and multi-functional components: PV-Thermal collectors.

description: Photonic crystals and metamaterials have emerged as two classes of tailorable materials that enable precise control of light. Plasmonic crystals, which can be thought of as photonic crystals fabricated from plasmonic materials, Bragg scatter incident electromagnetic waves from a repeated unit cell. However, plasmonic crystals, like metamaterials, are composed of subwavelength unit cells. Here, we study terahertz plasmonic crystals of several periods in a two dimensional electron gas. This plasmonic medium is both extremely subwavelength ($\approx λ/100$) and reconfigurable through the application of voltages to metal electrodes. Weakly localized crystal surface states known as Tamm states are observed. By introducing an independently controlled plasmonic defect that interacts with the Tamm states, we demonstrate a frequency agile electromagnetically induced transparency phenomenon. The observed 50% ${\it in-situ}$ tuning of the plasmonic crystal band edges should be realizable in materials such as graphene to actively control the plasmonic crystal dispersion in the infrared.

description: Shock metamorphism in ordinary chondrites allows for reconstructing impact events between asteroids in the main asteroid belt. Shock-darkening of ordinary chondrites occurs at the onset of complete shock melting of the rock (>70 GPa) or injection of sulfide and metal melt into the cracks within solid silicates (\sim 50 GPa). Darkening of ordinary chondrites masks diagnostic silicate features observed in the reflectance spectrum of S-complex asteroids so they appear similar to C/X-complex asteroids. In this work, we investigate the shock pressure and associated metamorphism pattern in rubble-pile asteroids at impact velocities of 4-10 km/s. We use the iSALE shock physics code and implement two-dimensional models with simplified properties in order to quantify the influence of the following parameters on shock-darkening efficiency: impact velocity, porosity within the asteroid, impactor size, and ejection efficiency. We observe that, in rubble-pile asteroids, the velocity and size of the impactor are the constraining parameters in recording high-grade shock metamorphism. Yet, the recorded fraction of higher shock stages remains low (<0.2). Varying the porosity of the boulders from 10% to 30% does not significantly affect the distribution of pressure and fraction of shock-darkened material. The pressure distribution in rubble-pile asteroids is very similar to that of monolithic asteroids with the same porosity. Thus, producing significant volumes of high-degree shocked ordinary chondrites requires strong collision events (impact velocities above 8 km/s and/or large sizes of impactors). A large amount of asteroid material escapes during an impact event (up to 90%); however, only a small portion of the escaping material is shock-darkened (6%).

description: We investigate the current-voltage characteristics of a field-effect tunnelling transistor comprised of both monolayer and bilayer graphene with well-aligned crystallographic axes, separated by three layers of hexagonal boron nitride. Using a self-consistent description of the device's electrostatic configuration we relate the current to three distinct tunable voltages across the system and hence produce a two-dimensional map of the I-V characteristics in the low energy regime. We show that the use of gates either side of the heterostructure offers a fine degree of control over the device's rich array of characteristics, as does varying the twist between the graphene electrodes.

description: Over the past five years, 2010-2015, we have observed, in the near infrared (IR), the maximum magnetic field strengths for 4145 sunspot umbrae. Herein we distinguish field strengths from field flux. (Most solar magnetographs measure flux). Maximum field strength in umbrae is co-spatial with the position of umbral minimum brightness (Norton and Gilman, 2004). We measure field strength by the Zeeman splitting of the Fe 15648.5 A spectral line. We show that in the IR no cycle dependence on average maximum field strength (2050 G) has been found +/- 20 Gauss. A similar analysis of 17,450 spots observed by the Helioseismic and Magnetic Imager onboard the Solar Dynamics Observatory reveal the same cycle independence +/- 0.18 G., or a variance of 0.01%. This is found not to change over the ongoing 2010-2015 minimum to maximum cycle. Conclude the average maximum umbral fields on the Sun are constant with time.

description: We present multi-wavelength analysis of a quasi-periodic pulsation (QPP) observed in the hard X-ray, radio, and extreme-ultraviolet (EUV) channels during an M1.9 flare occurred on 23-24 September 2011. The non-thermal hard X-ray emission in 25-50 keV observed by RHESSI shows five distinct impulsive peaks of decaying amplitude with a period of about three minutes. Similar QPP was observed in the microwave emission recorded by the Nobeyama Radioheliograph and Polarimeter in the 8.8, 15, 17 GHz channels. Interestingly, the 3-min QPP was also observed in the metric and decimetric radio frequencies (25-180, 245, 610 MHz) as repetitive type III bursts. Multi-wavelength observations from the SDO/AIA, Hinode/SOT, and STEREO/SECCHI suggest a fan-spine topology at the eruption site, associated with the formation of a quasi-circular ribbon during the flare. A small filament was observed below the fan-loops before the flare onset. The filament rose slowly and interacted with the ambient field. This behaviour was followed by an untwisting motion of the filament. Two different structures of the filament showed $\sim$3-min periodic alternate rotation in the clockwise and counterclockwise directions. The 3-min QPP was found to highly correlate with 3-min oscillations in a nearby sunspot. We suggest that the periodic reconnection (modulated either by sunspot slow-mode wave or by untwisting filament) at a magnetic null-point most likely causes the repetitive particle acceleration, generating the QPP observed in hard X-ray, microwave and type III radio bursts.

description: The purpose of this Discussion Paper is to report the observations of the Strong Culture, Strong Families program run for Aboriginal male detainees and their families in the Alexander Maconachie Centre, which is a prison and remand centre in the Australian Capital Territory. The paper aims to draw on the observations to examine and explain the program in the context of (1) parenting in prison and the creation of positive parenting experiences; (2) connecting Aboriginal and Torres Strait Islander detainees to family, identity and culture in the context of desistance and restorative justice; and, (3) understanding the program as an innovative Indigenous justice program. The research also asks important questions about the policy and wider justice context in which such programs are developed and take place.

description: Many researchers have recognized the value of investigating the history of race contact in Australia, but too few have sought to explain in detail why the Aboriginal population declined so much and so rapidly when colonization advanced across the continent. The central aim of this thesis is to identify and assess the impact of the major causes of Aboriginal population collapse in the Riverland (Murray River) region of South Australia. It is estimated that prior to 1800 the population density of the Riverland was between 0.3 and 0.5 km^ per person with a total population for the region of around 3000. In 1881 the South Australian State Census enumerated just 14 Aboriginal people for the Riverland region. The population collapse has been viewed in two stages. The first has been termed pathological contact and is considered to be the major cause of the collapse. Introduced venereal syphilis, gonorrhoea and smallpox spread ahead of the major European frontiers of South Australia causing extreme mortality among the Riverland Aborigines. The second stage began after European settlement of South Australia. Violent clashes were quick to erupt on the overland cattle route which linked the settlement of Adelaide with the Eastern settlements. The combined effect resulted in an increase in the mortality rate, a decrease in the fertility rate and social and economic disruption. The population was unable to recover.

matter, plant wide Manufacturing Execution Systems (MES), are more likely to significantly improve key business
metrics such as Net Profits, EBITDA, and Return on Assets. These practices are based on identification of risk factors,
ensuring the right trigger and event capture mechanisms are in place so that every failure becomes a guide post for
improvement. We identify weaknesses in current approaches and focus on process improvements - continuous
improvements in manufacturing, to drive up “Run Through Yield” and to improve profitability. This paper presents

description: Solar cells showing too large pre-breakdown currents, which might flow for unintentional reverse biasing by local shading, cannot be used since they would lead to thermal damage of the module. To be able to reduce the number of off-specification cells, the origin of the reverse current needs to be investigated. Pre-breakdown mechanisms in semiconductors exhibit characteristic temperature dependences. We present temperature-dependent lock-in thermography (LIT) measurements as well as illuminated LIT investigations under reverse bias that facilitate the identification of the type of breakdown observed at certain sites. There are both local regions with positive and with negative temperature coefficient of the breakdown current. It turns out that grown-in recombinative crystal defects lead to regions of local soft pre-breakdown sites. However, outside of these regions there are often some additional sites where a hard breakdown occurs which may even dominate at higher reverse bias. Lock-in EBIC images show that in the latter regions the cell surface, as a result of the acidic texturization etch, contains cone-shaped
holes which act as avalanche breakdown sites.

description: Objectives.

To determine that there are no differences between the application of the manual technique of inhibition of the suboccipital muscles with respect to the application of the INYBI instrument on the suboccipital musculature and to confirm that in both cases the patient experiences improvement in the different variables studied.

Material and methods.

Randomised, blinded, longitudinal, prospective and controlled clinical trial. A total of 58 subjects were included in the study, 45 women and 13 men; randomly distributed in two groups, experimental (29), who received the INYBI instrumental application on the suboccipital musculature and control (29), who received the manual technique of inhibition of the suboccipital musculature. Health levels were recorded using the Neck Disability Index test. In both groups, pre-, post- and post 45 min. measurements were taken of pain thresholds over the trigger points of the upper trapezius and posterior rectus maximus, using a pressure algometer; pain intensity, using a pain scale (EVA); cervical goniometry (Clinometrer Plaincode); atlas rotation, using the FRT atlas rotation test; and mouth opening, using a caliper foot.

Results.

There are no statistically significant differences between the experimental group and the control group (p> 0.05) in any of the variables. The trigger points of both the upper trapezius and the greater posterior rectus experienced an improvement in terms of pain assessment, with the trigger points of both trapezius experiencing the most significant improvement (p<0.001). We found significant increases in cervical mobility in flexion, extension, left rotation and right lateroflexion (p<0.05). We also found significant changes in mouth opening (p<0.05), atlas mobility in rotation (p<0.05) and in the VAS pain scale (p<0.05).

Conclusions.

The application of the ‘INYBI’ instrument can replace the manual technique of suboccipital inhibition whenever the physiotherapist considers it appropriate and both the manual and instrumental techniques are considered as an indication for the treatment of chronic mechanical cervicalgia.
Queensland and the aboriginal problem, 1838-1901

description: The Aboriginals Protection and Restriction of the Sale of Opium Act, introduced by the Queensland parliament in 1897, was the most important of the various pieces of legislation affecting Aborigines passed by the Australian colonies. It attempted to improve the condition of Aborigines by providing safeguards on the terms of their employment and by confining those not employed to reserves where, it was expected, they would no longer be adversely affected by contact with Europeans and others. The thesis argues that, contrary to the views of other writers, the 1897 Act was consistent with a long tradition of humanitarian attempts to produce an effective protection system. To understand the Act fully that tradition must be studied in depth. The Preface summarises the legislation and the Introduction states the reasons for studying this topic, reviews related literature and puts the argument to be advanced. The thesis is in two parts, the first dealing with efforts before the 1890s to assist the Aborigines and the second with the changed circumstances which caused the government to take action, the Act and the immediate aftermath. The first three chapters in Part l deal with the work of the Lutheran missionaries who arrived in Moreton Bay in 1838, the experience of the Presbyterian missionary, William Ridley, and the campaign of the former Native Police commandant, Frederick Walker, on behalf of the Aborigines. The opposing views of the squatters, on one hand, and churchmen and other humanitarians, on the other, are examined in the next three chapters. Then, the failure of Edward Fuller's mission on Fraser island is contrasted with the partial success of the first Aboriginal reserve at Mackay. Three chapters are given to considering the practical work of the two Aborigines commissions in the 1870s along with the impractical idealism of the Roman Catholic missionary, Father Duncan McNab. The collapse of humanitarian effort in the late 1870s and early 1880s is examined as a prelude to the resurgence of missionary work, particularly by the Lutherans in northern Queensland, in the late 1880s. In Part 2 close attention is given over several chapters to Archibald Meston, because of the part he played in devising a workable protection system and forcing it upon a hesitant government. The passage of the 1897 legislation through parliament is considered in some detail, as the debates clarify contemporary political positions and community attitudes. In the last two chapters the administration of the new law in the period before 1901, when an important amendment was made, is briefly surveyed. This leads to some reflections on the previous lack of effective administration in Aboriginal affairs in Queensland and its ready acceptance in the 1890s.

description: The high near-field enhancement occurring in the vicinity of metallic nanoparticles (MNPs) sustaining
surface plasmons can only be fully exploited in photovoltaic devices if the MNPs are placed inside their
semiconducting material, in the photoactive region. In this work an experimental procedure is studied to embed
MNPs in gallium arsenide (GaAs) and silicon (Si), which can be applied to other semiconductor host materials. The
approach consists in spin-coating colloidal MNPs dispersed in solution onto the substrate surface. Then a capping
layer of the same material as the substrate is deposited on top to embed the MNPs in the semiconductor. The
extinction spectra of silver (Ag) and gold (Au) MNPs embedded in GaAs and Si is modeled with Mie theory for
comparison with optical measurements.
This contribution constitutes the initial step towards the realization of quantum-dot intermediate band solar cells
(QD-IBSC) with MNPs.

description: The role of the side channels in the continuous-variable quantum key distribution is studied. It is shown how the information leakage through a side channel from the trusted sender station increases the vulnerability of the protocols to the eavesdropping in the main quantum communication channel. Moreover, the untrusted noise infusion by an eavesdropper on the trusted receiving side breaks the security even for a purely attenuating main quantum channel. As a method to compensate for the effect of the side-channel leakage on the sender side, we suggest several types of manipulations on the side-channel input. It is shown that by applying the modulated coherent light on the input of the side channel that is optimally correlated to the modulation on the main signal and optionally, introducing additional squeezing in the case of the squeezed-state protocol, the negative influence of the lossy side channel on the sender side can be completely removed. For the trusted receiving side, the method of optimal monitoring of the residual noise from the side-channel noise infusion is suggested and shown to be able to completely eliminate the presence of the noisy side channel. We therefore prove that the side-channel effects can be completely removed using feasible operations if the trusted parties access the respective parts of the side channels.

description: With the ultimate goal of developing rare-earth doped chalcogenide fiber fabrication for sensing, amplification, and laser applications, a core/clad germanium-gallium sulfide fiber doped with Pr$^{3+}$ has been fabricated. The compositions of the core and the clad were selected to ensure the positive $Δ$n by adding CdI$_2$ and CsCl, respectively, in the GeS$_2$ -Ga$_2$S$_3$ matrix. The choice of these compositions was also justified from experimental parameters, including characteristic temperatures and viscosity. Moreover, the permanent photo writability of the sulfide glass family by a femtosecond laser is investigated from the perspective of Bragg grating photo-inscription. Structural investigations by Raman spectroscopy are presented and the effect of the Pr$^{3+}$ rare-earth ion on the structure is underlined. Finally, the emission of the step-index fiber, made by the rod-in-tube technique between 3.1 $μ$m and 5.5 $μ$m (by pumping at 1.55 $μ$m), is demonstrated.

description: Targeted delivery of oligonucleotides or small molecular drugs to hepatocytes, the liver's parenchymal cells, is challenging without targeting moiety due to the highly efficient mononuclear phagocyte system (MPS) of the liver. The MPS comprises Kupffer cells and specialized sinusoidal endothelial cells, efficiently clearing nanocarriers regardless of their size and surface properties. Physiologically, this non-parenchymal shield protects hepatocytes; however, these local barriers must be overcome for drug delivery. Nanocarrier structural properties strongly influence tissue penetration, in vivo pharmacokinetics, and biodistribution profile. Here we demonstrate the in vivo biodistribution of polyplex micelles formed by polyion complexation of short interfering (si)RNA with modified poly(ethylene glycol)-block-poly(allyl glycidyl ether) (PEG-b-PAGE) diblock copolymer that carries amino moieties in the side chain. The ratio between PEG corona and siRNA complexed PAGE core of polyplex micelles was chemically varied by altering the degree of polymerization of PAGE. Applying Raman-spectroscopy and dynamic in silico modeling on the polyplex micelles, we determined the corona-core ratio (CCR) and visualized the possible micellar structure with varying CCR. The results for this model system reveal that polyplex micelles with higher CCR, i.e., better PEG coverage, exclusively accumulate and thus allow passive cell-type-specific targeting towards hepatocytes, overcoming the macrophage-rich reticuloendothelial barrier of the liver.

description: In this work the applicability of the recently proposed luminescence based series resistance measurement methods on typical cell processing problems in industry is investigated. The experimentally determined values of different methods are compared on mono- and multicrystalline cells. The method RsPL based on PL imaging shows the best results on multi material. In a second step it is tested whether the Rs values obtained with RsPL allow quantitative conclusions about the influence of high local series resistances on solar cell efficiency. Therefore a new procedure based on a simple network model is introduced to calculate global values from the Rs images. The values obtained with this procedure show only a slightly different correlation to the fill factor than it is theoretically expected. Finally, it is concluded from investigations of the impact of reduced measurement times that an inline measurement with quantitative reliable results is possible with data acquisition times of <1s.

description: Spatial self-organization emerges in distributed systems exhibiting local interactions when nonlinearities and the appropriate propagation of signals are at work. These kinds of phenomena can be modeled with different frameworks, typically cellular automata or reaction-diffusion systems. A different class of dynamical processes involves the correlated movement of agents over space, which can be mediated through chemotactic movement or minimization of cell-cell interaction energy. A classic example of the latter is given by the formation of spatially segregated assemblies when cells display differential adhesion. Here we consider a new class of dynamical models, involving cell adhesion among two stochastically exchangeable cell states as a minimal model capable of exhibiting well-defined, ordered spatial patterns. Our results suggest that a whole space of pattern-forming rules is hosted by the combination of physical differential adhesion and the value of probabilities modulating cell phenotypic switching, showing that Turing-like patterns can be obtained without resorting to reaction-diffusion processes. If the model is expanded allowing cells to proliferate and die in an environment where diffusible nutrient and toxic waste are at play, different phases are observed, characterized by regularly spaced patterns. The analysis of the parameter space reveals that certain phases reach higher population levels than other modes of organization. A detailed exploration of the mean-field theory is also presented. Finally we let populations of cells with different adhesion matrices compete for reproduction, showing that, in our model, structural organization can improve the fitness of a given cell population. The implications of these results for ecological and evolutionary models of pattern formation and the emergence of multicellularity are outlined.

description: This study aims to investigate the association between neighborhood-level factors and COVID-19 incidence in Scotland from a spatiotemporal perspective. The outcome variable is the COVID-19 incidence in Scotland. Based on the identification of the wave peaks for COVID-19 cases between 2020 and 2021, confirmed COVID-19 cases in Scotland can be divided into four phases. To model the COVID-19 incidence, sixteen neighborhood factors are chosen as the predictors. Geographical random forest models are used to examine spatiotemporal variation in major determinants of COVID-19 incidence. The spatial analysis indicates that proportion of religious people is the most strongly associated with COVID-19 incidence in southern Scotland, whereas particulate matter is the most strongly associated with COVID-19 incidence in northern Scotland. Also, crowded households, prepandemic emergency admission rates, and health and social workers are the most strongly associated with COVID-19 incidence in eastern and central Scotland, respectively. A possible explanation is that the association between predictors and COVID-19 incidence might be influenced by local context (e.g., people’s lifestyles), which is spatially variant across Scotland. The temporal analysis indicates that dominant factors associated with COVID-19 incidence also vary across different phases, suggesting that pandemic-related policy should take spatiotemporal variations into account.

description: Momentum feedback from isolated supernova remnants (SNRs) have been increasingly recognized by modern cosmological simulations as a resolution-independent means to implement the effects of feedback in galaxies, such as turbulence and winds. However, the integrated momentum yield from SNRs is uncertain due to the effects of SN clustering and interstellar medium (ISM) inhomogeneities. In this paper, we use spatially-resolved observations of the prominent 10-kpc star-forming ring of M31 to test models of mass-weighted ISM turbulence driven by momentum feedback from isolated, non-overlapping SNRs. We use a detailed stellar-age distribution (SAD) map from the Panchromatic Hubble Andromeda Treasury (PHAT) survey, observationally-constrained SN delay-time distributions, and maps of the atomic and molecular hydrogen to estimate the mass-weighted velocity dispersion using the Martizzi et al. ISM turbulence model. Our estimates are within a factor of 2 of the observed mass-weighted velocity dispersion in most of the ring, but exceed observations at densities $\lesssim 0.2$ cm$^{-3}$ and SN rates $>2.1\times 10^{-4}$ SN yr$^{-1}$ kpc$^{-2}$, even after accounting for plausible variations in stellar-age distribution models and ISM scale height assumptions. We conclude that at high SN rates the momentum deposited is most likely suppressed by the non-linear effects of SN clustering, while at low densities, SNRs reach pressure equilibrium before the cooling phase. These corrections should be introduced in models of momentum-driven feedback and ISM turbulence.

description: This thesis provides an update to the Aboriginal and environmental histories of the ‘high country’ in southeastern Australia from the terminal Pleistocene to the recent past. Its focus is the Namadgi Ranges, representing the northern-most outliers of the Australian Alps. The study combines archaeological excavations of rock shelter sites – from Wee Jasper in the north to the southern Namadgi valleys – with environmental reconstructions from adjacent peatlands. In a context of changing local environments, the findings provide new perspectives on when and how Aboriginal people were active in the mountains, and allow for a re-evaluation of existing archaeological models of occupation and technological change. AMS radiocarbon dates, sediment geochemistry, quantitative stone artefact analyses and other proxies contribute to solidifying the chronology and characteristics of high country habitation. Evidence of terminal Pleistocene activities is found at Wee Jasper in the Namadgi foothills, but remains elusive at higher elevations (> 1000 m). The revised datasets also reveal a previously unidentified period of low-intensity habitation across the ranges from the early to mid Holocene period (8000 to 5000 BP), possibly in response to a Holocene ‘climatic optimum’. The new evidence suggests that people may have largely abandoned the high country from 5000 or 4500 BP. From 2000 BP, however, evidence of habitation reappears, culminating in evidence for a maximum of occupation during the past 1000 years. In combination with an evaluation of known archaeological data from the high country and around its margins, the findings presented herein contradict several existing occupational and technological models, and also caution against the application of broad-scale cultural models across southeastern Australia. A regional environmental history is constructed by analyses of sediments that started to build up 16,000 years ago as the climate warmed. Fire event reconstruction based on charcoal, stratigraphic clues in peat sediments, geochemical signatures of landscape productivity and instability, and a faunal record from Wee Jasper provide a detailed record of change. Comparison of the archaeological and palaeoenvironmental datasets reveals a potential link in these two records, in the form of a tentatively identified signal of anthropogenic burning during the early to mid Holocene. More generally, the environmental history provides a backdrop of changing climates and landscape processes to which Aboriginal people adapted and responded over thousands of years.
Dealing with disorder : strategies of accommodation among the Southern Pitjantjatjara, Australia

description: I have utilised the orthography favoured by teachers and organisations associated with the Pitjantjatjara; my first lessons in the language were taught by Nancy Sheppard, previously of Ernabella who used this system (cf.Sheppard,1975). Pitjantjatjara uses seventeen consonants, and six vowels. The plosives p, k, t and tj are unaspirated. The language has two sounds indicated by r; a rolled r, symbolised as rr; and a retroflexed r. I have not indicated these retroflexes in the text, but point out here that the two words containing retroflexed r so.unds I use most frequently in the thesis are malu (red kangaroo), a retroflexed lateral; and anangu (Aboriginal person), a retroflexed nasal. There are three long vowel sounds, symbolised as ii, aa and uu; short vowels are i as in 'hit'; a as in 'cut' and u as in 'put'. Consonants are pronounced as follows: tj as an unaspirated English 'j'; ng as in 'long'; ny as in 'canyon'; ly has no English equivalent; w, y and m are pronounced as in English.

description: This study concerns a solar PV/T hybrid air collector which can be integrated into a building roof. It is
composed of photovoltaic modules that can be ventilated or not on the underside through an insulated air gap. Firstly,
a steady state 2D model of the component following a nodal approach is presented. Secondly, the experimental study
carried out under controlled radiation conditions on a test bench mounted in the laboratory under a solar simulator is
described. An experimental comparison is performed between the calculated and the measured data. Finally, an
experimental parametric study is realized in order to determine the influence of factors such as the thickness of the air
gap on the thermal performance of the system. In a further step, the prototype will be studied under a full building
integration setup.
