description: We apply the recently introduced Silicon Nitride Thermal Oxidation (SiNTO) process for the industrial
fabrication of silicon solar cells that feature a thermal oxide-passivated rear surface. The SiNTO process utilises a
SiNX anti-reflection layer for masking the front side of the solar cell during the thermal oxidation process. This
masking layer limits the growth of the thermal oxide to the uncoated rear surface. Laser fired contact (LFC)
technology is applied to form the local rear contacts. An efficiency of 18.6% (annealed) and 18.4 % (stable,
independently confirmed) is achieved for a PERC device fabricated from boron-doped Czochralski-silicon by means
of the SiNTO process. The average efficiency of a batch of 34 SiNTO cells is 18.2%, measured after fabrication (not
stabilised). Parallel processed Al-BSF references reach average efficiencies of 17.7%. Thus, the SiNTO approach
enables an efficiency increase of 0.5% absolute compared to conventional Al-BSF technology. When introducing
soldering pads, the efficiency gain for SiNTO compared to Al-BSF cells even increases to 0.8% absolute. Finally, we
use a comprehensive analytical model to estimate the optimum bulk resistivity for locally contacted devices
fabricated from conventional Czochralski silicon material. These calculations account for the bulk recombination
caused by the formation of boron-oxygen complexes under carrier injection.

description: The thesis examines what it means to bear witness through art. The complexity of bearing witness is discussed with reference to the writing of Giorgio Agamben and Georges Didi-Huberman, and the artwork of Broombeg and Channerin, Artur Zmejewski and Bindi Cole. My own lens-based practice offers a method of witnessing events at a temporal remove. Specifically, I focus my gaze on colonialism in my birthplace of South Africa. My photographic series Books on a White Background and the video The Miners Companion use the colonial archive as a pivot to critique western constructs of knowledge, whiteness, colonial and imperial histories.

description: Multi-object spectrographs have opened a new window on the analyses of the chemo-dynamical properties of old Milky Way stars. These analyses allow us to trace back the internal mechanisms and the external factors that have influenced the evolution of our Galaxy, and therefore understand fundamental aspects of galaxy evolution in general. Here, we present recent results from the RAdial Velocity Experiment (RAVE) and the Gaia-ESO survey. These surveys explore the Milky Way properties in different ways, in terms of sample size and selection, magnitude range, and spectral resolution. We focus here on (i) the first direct detection of evidence for radial migration within the thin disc, providing insight into the history of spiral structure of the Milky Way, and (ii) the chemo-dynamical characterisation of the metal-weak thick and thin discs, for which chemo-dynamical models still have difficulties in reproducing.

Model's sparse representation based on reduced mixed GMsFE basis methods

description: In this paper, we propose a model's sparse representation based on reduced mixed generalized multiscale finite element (GMsFE) basis methods for elliptic PDEs with random inputs. Mixed generalized multiscale finite element method (GMsFEM) is one of the accurate and efficient approaches to solve multiscale problem in a coarse grid with local mass conservation. When the inputs of the PDEs are parameterized by the random variables, the GMsFE basis functions usually depend on the random parameters. This leads to a large number degree of freedoms for the mixed GMsFEM and substantially impacts on the computation efficiency. In order to overcome the difficulty, we develop reduced mixed GMsFE basis methods such that the multiscale basis functions are independent of the random parameters and span a low-dimensional space. To this end, a greedy algorithm is used to find a set of optimal samples from a training set scattered in the parameter space. Reduced mixed GMsFE basis functions are constructed based on the optimal samples using two optimal sampling strategies: basis-oriented cross-validation and proper orthogonal decomposition. Although the dimension of the space spanned by the reduced mixed GMsFE basis functions is much smaller than the dimension of the original full order model, the online computation still depends on the number of coarse degree of freedoms. To significantly improve the online computation, we integrate the reduced mixed GMsFE basis methods with sparse tensor approximation and obtain a sparse representation for the model's outputs. The sparse representation is very efficient for evaluating the model's outputs for many instances of parameters. To illustrate the efficacy of the proposed methods, we present a few numerical examples for multsicale problems with random inputs.

description: This work describes the behaviour of water molecules in 1-butyl-3-methylimidazolium tetrafluoroborate ionic liquid under nanoconfinement between graphene sheets. By means of molecular dynamics simulations, an adsorption of water molecules at the graphene surface is studied. A depletion of water molecules in the vicinity of the neutral and negatively charged graphene surfaces and their adsorption at the positively charged surface are observed in line with the preferential hydration of the ionic liquid anions. The findings are appropriately described using a two-level statistical model. The confinement effect on the structure and dynamics of the mixtures is thoroughly analyzed using the density and the potential of mean force profiles, as well as by the vibrational densities of states of water molecules near the graphene surface. The orientation of water molecules and the water-induced structural transitions in the layer closest to the graphene surface are also discussed.

description: Simulation software programs are today important tools for the design, the yield prediction and the study of economic viability of photovoltaic systems. Although possible unexpected variability of the solar energy and quality levels associated to manufacturing and sorting process are well known, the common simulation tools still only run with fixed values, neglecting any source of variation. This paper outlines a new approach to the photovoltaic system analysis and
simulation by considering distributions and uncertainties associated to critical input parameters. It shows the advantages from economic and technical perspective. The new approach is applied as example in two ways:
1. Implemented in the SolEm PV software package to analyze how tolerance influence the specific annual yield.
2. To a cost model determining cost per kWh of concentrated photovoltaic systems (CPV).
Basic Properties of Conductivity and Normal Hall Effect in the Periodic Anderson Model

description: Exact formulas of diagonal conductivity $σ_{xx}$ and Hall conductivity $σ_{xy}$ are derived from the Kubo formula in hybridized two-orbital systems with arbitrary band dispersions. On the basis of the theoretical framework for the Fermi liquid based on these formulas, the ground-state properties of the periodic Anderson model with electron correlation and weak impurity scattering are studied on the square lattice. It is shown that imbalance of the mass-renormalization factors in $σ_{xx}$ and $σ_{xy}$ causes remarkable increase in the valence-fluctuation regime as the f level increases while the cancellation of the renormalization factors causes slight increase in $σ_{xx}$ and $σ_{xy}$ in the Kondo regime. The Hall coefficient $R_{\rm H}$ shows almost constant behavior in both the regimes. Near half filling, $R_{\rm H}$ is expressed by the total hole density as $R_{\rm H}=1/(\bar{n}_{\rm hole}e)$ while $R_{\rm H}$ approaches zero near quarter filling, which reflects the curvature of the Fermi surface. These results hold as far as the damping rate for f electrons is less than about $10~\%$ of the renormalized hybridization gap. From these results we discuss pressure dependence of residual resistivity and normal Hall effect in Ce- and Yb-based heavy electron systems.

description: A sterile neutrino is a well-motivated and widely studied dark matter candidate. The most straightforward realization of sterile neutrino dark matter, through the Dodelson-Widrow mechanism, is now ruled out by a combination of X-ray and Lyman-αmeasurements. An alternative production mechanism that is becoming increasingly popular in the literature is the freeze-in mechanism, involving frameworks where a feeble coupling to a particle - usually a scalar beyond the Standard Model - in the thermal bath results in a gradual accumulation of the sterile neutrino dark matter abundance. This article reviews the various motivations for realizing such frameworks in the literature, their common characteristic features, and phenomenological signatures.

description: The Lagrangian dynamics of a single fluid element within a self-gravitational matter field is intrinsically non-local due to the presence of the tidal force. This complicates the theoretical investigation of the non-linear evolution of various cosmic objects, e.g. dark matter halos, in the context of Lagrangian fluid dynamics, since a fluid parcel with given initial density and shape may evolve differently depending on their environments. In this paper, we provide a statistical solution that could decouple this environmental dependence. After deriving the probability distribution evolution equation of the matter field, our method produces a set of closed ordinary differential equations whose solution is uniquely determined by the initial condition of the fluid element. Mathematically, it corresponds to the projected characteristic curve of the transport equation of the density-weighted probability density function (PDF). Consequently it is guaranteed that the one-point PDF would be preserved by evolving these local, yet non-linear, curves with the same set of initial data as the real system. Physically, these trajectories describe the mean evolution averaged over all environments by substituting the tidal tensor with its conditional average. For Gaussian distributed dynamical variables, this mean tidal tensor is simply proportional to the velocity shear tensor, and the dynamical system would recover the prediction of Zel'dovich approximation (ZA) with the further assumption of the linearized continuity equation. For Weakly non-Gaussian field, the averaged tidal tensor could be expanded perturbatively as a function of all relevant dynamical variables whose coefficients are determined by the statistics of the field.

description: In settings where only unlabelled speech data is available, speech technology needs to be developed without transcriptions, pronunciation dictionaries, or language modelling text. A similar problem is faced when modelling infant language acquisition. In these cases, categorical linguistic structure needs to be discovered directly from speech audio. We present a novel unsupervised Bayesian model that segments unlabelled speech and clusters the segments into hypothesized word groupings. The result is a complete unsupervised tokenization of the input speech in terms of discovered word types. In our approach, a potential word segment (of arbitrary length) is embedded in a fixed-dimensional acoustic vector space. The model, implemented as a Gibbs sampler, then builds a whole-word acoustic model in this space while jointly performing segmentation. We report word error rates in a small-vocabulary connected digit recognition task by mapping the unsupervised decoded output to ground truth transcriptions. The model achieves around 20% error rate, outperforming a previous HMM-based system by about 10% absolute. Moreover, in contrast to the baseline, our model does not require a pre-specified vocabulary size.

description: An effective way of achieving a selective emitter is by using laser doping to produce the heavily doped regions
beneath the metal contacts. Such technique allows simultaneous patterning of the dielectric and laser induced diffusion, while
only subjecting the substrate to localised heating. Laser Doped Selective Emitter (LDSE) solar cell technology has been
shown to achieve quite significant improvement over Screen-Printed (SP) Solar Cell due to better blue response and lower
metal shading losses among other benefits. In this paper, LDSE cells were fabricated in a screen-printed line in industrial
environment, with the exceptions of the two end processes: 1) laser doping and 2) metallisation via plating to replace front
silver contact. By using continuous wave (cw) green laser to do the laser doping, most of the surface damage normally caused
by nanosecond q-switched lasers can be avoided. A scan speed of 2 meter/second or higher was found to give good laser
doping profile. Such high speed is suitable for mass-production. Self-aligned nickel and copper plating were then done using
a novel contactless light induced plating (LIP) method. The laser doped regions are typically 10-15 μm wide, with metal lines
of only 35 μm wide after plating, leading to JSC as high as 37.7 mA/cm2. A cell efficiency approaching 19.0% on industrial
grade 6” 1.cm p-type Czochalski, with latest batch average of 18.7% was achieved. In this paper, some of the most critical
optimisation works done for these cells will be discussed and detailed analysis of the results will be presented.

description: The research for this candidature responds to the metaphorical explosion of the conceptual frame that was built around me to create my Jewish identity. Through my reading of Kabbalistic Lurianic principles, I argue that what shattered were symbolic shards of the frame which became embedded within the surrounding landscape. My art practice as such has consisted of two key aspects: To uncover these fragments, primarily through a generative methodology of wandering, and by partaking in art rituals. In doing so I seek to return these shards—evoking what Kabbalists describe as a rectification process—a remedying of nature and a reconstruction of my own Jewish identity.

description: This paper presents a detailed analysis of the uncertainties for the spectral mismatch of micro-morph thin film solar cell. The uncertainty analysis involves Monte Carlo simulation of wavelength-dependent random errors and addition of systematic (bias) errors with different error distributions, respectively, for different types of solar simulators. The mechanism of spectral mismatch of micro-morph double junction solar cell is analyzed followed by the error sensitivity study of wavelength integration limits to the uncertainty of spectral mismatch and the quantification of final uncertainty which combines the random error and the bias error for different solar simulators. It demonstrated that depending on the error distribution and the magnitude the uncertainty for the spectral mismatch factor varies between 1.0% to 10%, depending on the solar simulators used. The uncertainty of spectral mismatch error can be up to 200% for a specific wavelength integration range.

description: The dynamics of the fast growing PV market, constantly bringing up new module technologies or changing installation requirements, pose a challenge for modern PV inverters. These include e.g. the functional grounding of one active pole to avoid TCO corrosion in thin film modules or polarisation effects in back side contacted silicon cells or the use of string fuses for system protection. Another point of interest is the necessity to achieve high yield in real life condition by still being flexible in system designing concerning voltage windows of the inverter. This paper shall point out some recent trends in system design and the solutions a modern inverter can offer to the resulting new requirements.

description: The decay of a bound state weakly-coupled to a non-Hermitian tight-binding unstable continuum, i.e. a continuum of states comprising energies with positive imaginary part, is theoretically investigated. As compared to quantum decay in an Hermitian continuum, in the non-Hermitian case a richer scenario can be found as a result of non-unitary dynamics. Different behaviors are observed depending on the kind of instability of the continuum. These include complete or fractional decay in convectively-unstable continua, the absence of quantum decay for a bound state with energy embedded in the continuum loop, and unstable (secular) growth with pseudo exponential amplification in the absolutely-unstable regime. Analytical results are presented for a nearest-neighboring tight-binding continuum with asymmetric hopping rates $κ_1$ and $κ_2$, which shows a transition from convective to absolute instability when the sign $κ_1 κ_2$ changes from positive to negative. In the convectively unstable regime the model describes the decay of a bound state coupled to a tight-binding lattice with an imaginary gauge field, which shows a pseudo-Hermitian dynamics. In the absolutely-unstable regime, pseudo-Hermitian dynamics is broken and a pseudo exponential secular growth is observed.

description: The electrical grid specifications of Djibouti, at present time, are described by a 130 MW total power
installed, large variations in electric production and a limited distribution to town areas. Thus, energy supplying is
one of the most important politic purposes of the Djiboutian government, including large scale integration of
renewable power systems.
PV system off-grid electrification, in this context, is a pertinent choice because of a great solar potential and a large
number of off-grid sites dispatched all over the country. However, this context also incites us to make an intelligent
electrification and, therefore, to realize planning.
Consequently, the first part of this paper describes planning process. The two collateral first steps of this process are
solar atlas implementation from satellite data and geographical data consideration. Furthermore, we use satellite data
because of non existence of meteorological network in Djibouti. The final purpose of these two steps is photovoltaic
development potential mapping. Then, this map will be used to size and integrate suitable PV systems in the country.
Secondly, this study shows method used to create solar energy potential atlas of Djibouti from satellite data. These
data are computed to get hourly global horizontal irradiance maps. Then, by computing a diffuse fraction model, we
obtain diffuse and direct hourly horizontal irradiance maps. In the other part, by using a Digital Elevation Model, we
build diffuse and direct shading factor maps. Finally, results from this solar atlas implementation method are hourly
global horizontal irradiance maps with shading effect consideration.

description: In Österreich erhalten Medien zweierlei Förderungen. Zum einen gibt es eine offizielle, direkte Medienförderung wie zum Beispiel die Presseförderung, zum anderen eine inoffizielle, verdeckte Medienförderung in Form von Inseratenschaltungen öffentlicher Rechtsträger und staatsnahen Unternehmen. Letztere schalteten im Jahr 2022 gemeinsam rund 201,5 Mio. Euro an Werbung in periodischen Print- und Onlinemedien. Der größte Teil kommt dabei traditionell von der Bundesregierung. Bekannt sind diese Zahlen aufgrund des 2012 eingeführten Medientransparenzgesetzes, das die Bekanntgabe und Veröffentlichung von Inseratenschaltungen regelt. Die vorliegende Arbeit überprüft anhand der in § 3a Medientransparenzgesetz festgelegten inhaltlichen Anforderungen, inwiefern die von Bundes- und Landesregierungen in den Untersuchungszeiträumen Q4/2016 (Kabinett Kern) und Q4/2020 (Kabinett Kurz II) geschalteten Inserate diese erfüllen. Auch werden alle Inserate in einem ausgewählten Mediensample gezählt, um mögliche Steigerungen oder Abnahmen festzustellen. Als Ergebnis hat sich gezeigt, dass in beiden Untersuchungszeiträumen die inhaltlichen Anforderungen in einem großen Teil der Inserate nicht erfüllt wurden. Unter Kern entsprachen rund 40%, unter Kurz rund 37% nicht oder nur teilweise den inhaltlichen Anforderungen des Medientransparenzgesetzes. Bezüglich der Anzahl der Inserate wurde eine Abnahme bei kommerziellen Inseraten bei gleichzeitiger Zunahme von Inseraten öffentlicher Rechtsträger festgestellt.
description: In Austria, the media receive two types of funding. On the one hand, there is official, direct me-dia funding, such as press funding, and on the other hand, there is unofficial, hidden media funding in the form of advertisements placed by public legal entities and state-related compa-nies. The latter together placed around 201.5 million euros in advertising in periodic print and online media in 2022. The largest share traditionally comes from the federal government. These figures are known because of the Media Transparency Act introduced in 2012, which regulates the disclosure and publication of advertisements. On the basis of the content requirements laid down in § 3a of the Media Transparency Act, this study examines the extent to which the adver-tisements placed by federal and provincial governments in the periods under review, Q4/2016 (Kern cabinet) and Q4/2020 (2nd Kurz cabinet), meet these requirements. All advertisements in a selected media sample are also counted in order to determine possible increases or decreases. As a result, it was shown that the content requirements were not met in a large part of the adver-tisements in both periods under investigation. Under Kern about 40%, under Kurz about 37% did not or only partially meet the content requirements of the Media Transparency Act. With regard to the number of advertisements, a decrease in commercial advertisements and a simulta-neous increase in advertisements by public legal entities were found.

description: Solar modules mounted to a subsystem are directly affected by natural weathering. It has been found that certification processes including simulated weathering of UV-radiation, heat and moisture can not guarantee for a specific life time. The use of polymers in a photovoltaic-module (PV-module) is one of the most important factors in aging of PV-modules and therefore a methodological approach for analyzing the aging behavior of the polymeric
encapsulate materials is presented here. For extrapolation of degradation processes Arrhenius relationship is used as aging model focusing on simultaneous occurrence of different degradation processes. Results of mechanical tests can give information for numerical simulation of changing load-deflection behavior after aging. Thermal Analysis with DSC or TGA helps to understand structural changes happening in the polymeric material.

description: In this thesis, I analyse a selection of photographs and essays from the journal Documents (1929-1930), alongside the philosophy of Walter Benjamin and Georges Bataille. Through this configuration, I propose a theory of messianic nihilism. I focus on Benjamin and Bataille’s analysis of modernity and its apparatus of technological reproduction. I address this through the photographs of Karl Blossfeldt, Eli Lotar, and Jacques-André Boiffard as they interpenetrate with the texts published alongside them. Through the photography of Documents, I argue that ‘messianic nihilism’ emerges as a reconsidered relation to space, and time, that contests teleological notions of progress and the supremacy of language as a homogeneous form of communication.
Toward an asymptotic behaviour of the ABC dynamo

description: The ABC flow was originally introduced by Arnol'd to investigate Lagrangian chaos. It soon became the prototype example to illustrate magnetic-field amplification via fast dynamo action, i.e. dynamo action exhibiting magnetic-field amplification on a typical timescale independent of the electrical resistivity of the medium. Even though this flow is the most classical example for this important class of dynamos (with application to large-scale astrophysical objects), it was recently pointed out (Bouya Ismaël and Dormy Emmanuel, Phys. Fluids, 25 (2013) 037103) that the fast dynamo nature of this flow was unclear, as the growth rate still depended on the magnetic Reynolds number at the largest values available so far $(\text{Rm} = 25000)$ . Using state-of-the-art high-performance computing, we present high-resolution simulations (up to 40963) and extend the value of $\text{Rm}$ up to $ 5\cdot10^5$ . Interestingly, even at these huge values, the growth rate of the leading eigenmode still depends on the controlling parameter and an asymptotic regime is not reached yet. We show that the maximum growth rate is a decreasing function of $\text{Rm}$ for the largest values of $\text{Rm}$ we could achieve (as anticipated in the above-mentioned paper). Slowly damped oscillations might indicate either a new mode crossing or that the system is approaching the limit of an essential spectrum.

description: Strong correlation between the pre-breakdown sites visible in dark lock-in thermography due to local
heating and the intensity of spatially resolved electroluminescence of reverse-biased solar cells was observed. By
comparing differently texturised structurally similar solar cells we could show that the positions of the observed prebreakdown
sites are identical for acidic and alkaline texturised solar cells and therefore are not correlated with the
surface morphology. The pre-breakdown sites are directly related to bulk defects in the wafer. Nevertheless, the
breakdown voltage is lower for acidic texturised solar cells. The quantitative parameters of breakdown are
influenced by the texture. Also pre-breakdown sites at bulk defects are observed in areas without specific surface
features for alkaline texturised solar cells.

description: The entanglement-assisted stabilizer formalism provides a useful framework for constructing quantum error-correcting codes (QECC), which can transform arbitrary classical linear codes into entanglement-assisted quantum error correcting codes (EAQECCs) by using pre-shared entanglement between the sender and the receiver. In this paper, we construct five classes of entanglement-assisted quantum MDS (EAQMDS) codes based on classical MDS codes by exploiting one or more pre-shared maximally entangled states. We show that these EAQMDS codes have much larger minimum distance than the standard quantum MDS (QMDS) codes of the same length, and three classes of these EAQMDS codes consume only one pair of maximally entangled states.

description: In this study, the robustness of wafer identification using very small Data Matrix codes with a size of
only 0.8 x 3.2 mm² on mono- and multi-crystalline silicon wafers is investigated. The quality of different codes
concerning marking depth, laser-induced damage and robustness of code detection by automatic vision inspection is
investigated for the whole variety of different surfaces relevant for solar cell manufacturing. The laser marked Data
Matrix codes are read-out with the SICK Image Code Reader. To allow identification of Data Matrix codes in every
process step, codes with a groove depth of 18 μm minimum after texturisation are necessary. With respect to laserinduced
damage the codes should not be deeper than 22 μm. We developed two laser processes which generate
robust code structures while introducing only little laser damage which can be removed within an etch removal of
dE = 11 μm as it is typical for a standard texturisation process. For cell processes with surface texture on mono- and
multi-crystalline silicon average detection rates of 98 % are already achieved over the whole process sequence with
Data Matrix codes with an element size of 150 μm.
Quantum geometrodynamics with intrinsic time development

description: Quantum geometrodynamics with intrinsic time development is presented. Paradigm shift from full space-time covariance to spatial diffeomorphism invariance yields a non-vanishing Hamiltonian, a resolution of the `problem of time', and gauge-invariant temporal ordering in an ever expanding universe. Einstein's general relativity is a particular realization of a wider class of theories; and the framework prompts natural extensions and improvements, with the consequent dominance of Cotton-York potential at early times when the universe was small.

description: As-deposited TiO2 coatings are found permeable to water vapour under the “damp heat” conditions of 85 °C
and 85% relative humidity. They do not, therefore, protect underlying films or interfaces from any detrimental effects of
gaseous H2O at elevated temperature. Consequently, high-efficiency solar cells with a TiO2 antireflection coating and oxide
passivation could fail the damp-heat reliability test due to H2O diffusing through the TiO2 and degrading the underlying Si–
SiO2 interface. The TiO2 films, which were deposited at 400 °C by atmospheric pressure chemical vapour deposition, were
also densified by an 800 °C anneal. While the anneal might have reduced the films’ permeability to water vapour, it
degraded the underlying Si–SiO2 interface or possibly the silicon itself; the samples could not be repaired by a subsequent
forming-gas anneal.

description: This landscape analysis will address how evidence syntheses that assess health intervention effects and racial health equity engage stakeholders and guidance related to engaging diverse stakeholders in evidence syntheses. Given the poor reporting of stakeholder engagement in evidence syntheses in general, a focused review of systematic reviews and other evidence syntheses of interventions addressing racial health equity may offer the most targeted source for best practices in conducting and reporting stakeholder engagement. Additionally, a review of stakeholder engagement guidance documents to extract perspectives specific to racial health equity will help advance our understanding of how to best to engage stakeholders in the context of addressing racial health equity.

description: Multiple color selection techniques have been successful in identifying quasars from wide-field broad-band imaging survey data. Among the quasars that have been discovered so far, however, there is a redshift gap at $5 \lesssim {\rm z} \lesssim 5.7$ due to the limitations of filter sets in previous studies. In this work, we present a new selection technique of high redshift quasars using a sequence of medium-band filters: nine filters with central wavelengths from 625 to 1025 nm and bandwidths of 50 nm. Photometry with these medium-bands traces the spectral energy distribution (SED) of a source, similar to spectroscopy with resolution R $\sim$ 15. By conducting medium-band observations of high redshift quasars at 4.7 $\leq$ z $\leq$ 6.0 and brown dwarfs (the main contaminants in high redshift quasar selection) using the SED camera for QUasars in EArly uNiverse (SQUEAN) on the 2.1-m telescope at the McDonald Observatory, we show that these medium-band filters are superior to multi-color broad-band color section in separating high redshift quasars from brown dwarfs. In addition, we show that redshifts of high redshift quasars can be determined to an accuracy of $Δ{\rm z}/(1+{\rm z}) = 0.002$ -- $0.026$. The selection technique can be extended to z $\sim$ 7, suggesting that the medium-band observation can be powerful in identifying quasars even at the re-ionization epoch.

Designing Formally Correct Intermittent Systems

description: Batteryless energy harvesting devices (EHDs) enable computing in environments that are too harsh, remote, or inaccessible to support the required maintenance of a battery, opening the door to new applications in domains such as health wearables, disaster monitoring, and smart infrastructure. Instead of using a battery, an EHD harvests energy from its environment into a buffer and operates intermittently, only as energy is available. This operational cycle causes the device to experience frequent, arbitrary power failures that make correct programming difficult. To make progress, software relies on intermittent system support to save execution state before power failure and restore it after the device reboots. Mistakes in determining which state must be saved and where a save point should be made cause software to exhibit memory and timing bugs that would not occur on continuously powered program executions. As EHDs are envisioned to be remotely deployed, low-maintenance devices that run sensitive applications, software must execute reliably, without memory consistency or timing violations that could corrupt results or render the device inoperable. Unfortunately, existing intermittent systems rely on informal, undefined correctness notions that preclude proving such necessary correctness properties. This dissertation lays the foundation for designing formally correct intermittent systems by providing formal models and correctness definitions along with practical enforcement tools. First, we confirm the need for formal reasoning by showing how existing correctness notions are insufficient and lead to unaddressed bugs. We then present a formal model of intermittent execution and a correctness theorem, using these to design a runtime system that is provably correct with respect to memory state. Next, we show how reasoning about safe intermittent execution at the language level via types gives application programmers more control over how their applications execute on these unusual new devices and moreover leads to simpler, more modular system design. Finally, we address timing violations caused by intermittent execution. To that end, we create language abstractions a programmer can use to specify important timing properties and develop a compiler toolchain that generates correct-by-construction executables with respect to the specified timing constraints. Together, the contributions of this dissertation allow the development of intermittent systems that meet specified guarantees of time and memory consistency, improving programmability and reliability

description: At present inline measurements of antireflection coating (ARC) thickness are established, but there are still
open questions concerning the influence of a varying surface texture quality on accuracy of ARC thickness measurement.
Surface texture may be different due to process inhomogeneities. Thus, inline color inspection systems in production lines
are often only used to detect inhomogeneities or spots in the ARC in order to sort the cells into different optical quality
classes. This work aims at evaluating the possibilities and restrictions to determine the thickness of the ARC with inline
vision irrespective of the wafer surface. Special emphasis has been put on textured monocrystalline wafers. Considering the
reflection after texturisation the accuracy of ARC thickness measurement by color vision inspection may be improved
significantly. Finally, it has been shown that an inline measurement of the reflection after texturisation would be possible
with the same inline system and an aligned calibration.
Playing the Fool

description: This research project uses Walter Benjamin’s theories concerning the constellation and now-time (jetztzeit) within the context of Benjamin’s description of the historicist and the historical materialist found in Benjamin’s Theses on the Philosophy of History (1940). It seeks to use these theories as a methodological approach to art making. It will compare the historical materialist methodology with the art practice of Louise Lawler (amongst others) and look at how a similar methodology functions in my own practice. This methodological approach operates from an intentional position of unknowing, a position I describe as ‘playing the fool’. This self-reflexive process involves the development of a network of references which question the systemic apparatus which supports art making, the viewer and the exhibition context.
