description: The current study focuses on developing a mathematical model of human hand articulation, particularly in the context of optimizing a fabricated soft-robotic glove for individuals with impaired motor function in their upper limbs due to conditions such as spinal cord injuries or strokes. This model aims to optimize the design of the glove, which is being developed as part of the NeuroSuitUp project. The research delves into the theoretical background of neurological disorders like spinal cord injuries and strokes, as well as the biomechanics of the human hand. After providing an overview of the soft-robotics field, the study progresses to kinematic analysis, utilizing Denavit-Hartenberg parameters to describe the motion and geometry frames of the human finger. Subsequently, dynamic analysis is conducted using the Euler-Lagrange method, concluding to an assessment of inverse dynamics to calculate the torques generated by the fingers during basic movements. The findings are presented through torque plots for each finger phalanx over time, aiding in the future selection of pneumatic actuators for the soft-robotic glove. Finally, the study concludes with discussions on its implications and potential avenues for future research and improvement.

Αυτό το μοντέλο στοχεύει στη βελτιστοποίηση του σχεδιασμού του γαντιού, το οποίο αναπτύσσεται ως μέρος του έργου NeuroSuitUp και αναμένεται να βελτιώσει τη λειτουργικότητα του ρομποτικού γαντιού. Η έρευνα εμβαθύνει στο θεωρητικό υπόβαθρο των νευρολογικών διαταραχών όπως οι τραυματισμοί του νωτιαίου μυελού και τα εγκεφαλικά επεισόδια, καθώς και η εμβιομηχανική του ανθρώπινου χεριού. Μετά από μια περιεκτική αναφορά του πεδίου της μαλακής ρομποτικής (soft-robotics), η μελέτη προχωρά στην κινηματική ανάλυση, χρησιμοποιώντας τις παραμέτρους Denavit-Hartenberg για να περιγράψει την κίνηση και γεωμετρία του ανθρώπινου δακτύλου. Στη συνέχεια, πραγματοποιείται δυναμική ανάλυση χρησιμοποιώντας τη μέθοδο Euler-Lagrange, καταλήγοντας στην λύση της αντίστροφης δυναμικής για τον υπολογισμό των ροπών που δημιουργούνται από τα δάχτυλα κατά τη διάρκεια βασικών κινήσεων. Τα ευρήματα παρουσιάζονται μέσω διαγραμμάτων ροπής για κάθε φάλαγγα δακτύλου με την πάροδο του χρόνου, βοηθώντας στην μελλοντική επιλογή πνευματικών ενεργοποιητών για το ρομποτικό γάντι. Τέλος, η μελέτη ολοκληρώνεται με συζητήσεις σχετικά με τα αποτελέσματα και τις πιθανές οδούς για μελλοντική έρευνα και βελτίωση.

description: Orogenic type gold deposits are responsible for contributing over 75% of the Au recovered globally throughout history and Victoria contains one of the most prosperous orogenic gold regions ever discovered, producing approximately 2,500 tonnes of gold since the mid 1800’s. This investigation will combine principles from stable isotope geochemistry, petrography, micro-tectonics, thermodynamics, electrochemistry, and material science in ways not previously considered by the economic geology community. Results from this study will allow mineral explorationists to prioritise their targeting programs on both the regional and deposit-scale, as well as further the understanding of the key processes involved in the genesis of orogenic Au-type deposits and bonanza-grade gold zones.

description: Organic/inorganic hybrid solar cells based on silicon nanowires in a P3HT:[60]-PCBM blend on a
PEDOT:PSS/ITO/glass layer system were investigated. The nanowires were etched into silicon wafers, detached by
sonication in chlorobenzene and introduced into a P3HT:[60]-PCBM solution. Cells with nanowires reached an
efficiency of 4.1 %, higher by 10% relative as compared to classical polymer cells without nanowires prepared as
reference. The increase is attributed to a better charge transport towards the electrodes, or to a better charge
separation.

description: Symmetry-breaking quantum phase transitions play a key role in several condensed matter, cosmology and nuclear physics theoretical models. Its observation in real systems is often hampered by finite temperatures and limited control of the system parameters. In this work we report for the first time the experimental observation of the full quantum phase diagram across a transition where the spatial parity symmetry is broken. Our system is made of an ultra-cold gas with tunable attractive interactions trapped in a spatially symmetric double-well potential. At a critical value of the interaction strength, we observe a continuous quantum phase transition where the gas spontaneously localizes in one well or the other, thus breaking the underlying symmetry of the system. Furthermore, we show the robustness of the asymmetric state against controlled energy mismatch between the two wells. This is the result of hysteresis associated with an additional discontinuous quantum phase transition that we fully characterize. Our results pave the way to the study of quantum critical phenomena at finite temperature, the investigation of macroscopic quantum tunneling of the order parameter in the hysteretic regime and the production of strongly quantum entangled states at critical points.

description: A new model for a colloidal size-asymmetric binary mixture is proposed: The Square-Shoulder-Asakura-Oosawa. This belongs to the larger class of non-additive hard-spheres models and has the property that its effective pair formulation is exact whenever the solvent particle fits inside the interstitial region of three touching solute particles. Therefore one can study its properties from the equivalent one-component effective problem. Some remarks on the phase diagram of this new model are also addressed.

description: The surface passivation effects of HF terminated silicon surfaces using quinhydrone-methanol and
iodine-methanol are investigated. The surface recombination velocity (S) is demonstrated for various thicknesses and
resistivities of silicon substrates passivated with these chemical solutions. Quinhydrone-methanol (QHY-ME) has
bigger ionic radius and results in higher minority carrier lifetimes. It provides better chemical screening against
oxygen and is therefore much stable in air as compared to iodine methanol passivation. QHY-ME is easy, nonhazardous,
a room temperature passivation scheme, and gives repeatable results. It resulted in best minority carrier
lifetime of 3.3 ms for n-type high resistivity 100 -cm Si substrate (S of 7 cm/sec) and 1.1 ms for p-type low
resistivity 280 μm substrate (S of 10.2 cm/sec); both at an injection level of 1x1015 cm-3 thus proving its utility as an
important characterization tool for different types, resistivity and thicknesses of silicon substrates. The lifetime is
measured using the WCT-120 Sinton Lifetime Tester and surface recombination velocity extracted. The injection
level dependent lifetime of these chemically passivated silicon substrates is also demonstrated for the first time in this
paper in order to determine the change in surface properties with carrier density.

description: This work is a comparative study of the optical and chemical properties of Hydrogenated Silicon Nitride
films (SiNx:Hy) made with an atmospheric pressure PECVD (AP - Plasma Enhanced Chemical Vapor Deposition)
process under development and an industrial Low Pressure (LP) PECVD reactor. The AP-PECVD films are deposited
with a laboratory scale reactor using Ar, SiH4 and NH3 gas mixtures whereas the LP-PECVD silicon nitride is obtained in
a Centrotherm reactor with NH3 and SiH4 as reactive gases. The optical parameters (refractive index and extinction
coefficient) of the two silicon nitrides are compared before and after Rapid Thermal Annealing (RTA) by means of
ellipsometric measurements and New Amorphous dispersion law. To compare the different chemistries of the layers,
FTIR measurements are done, also before and after RTA. Si-H and N-H absorption peaks are related to the refractive
index showing that the same optical properties are obtained with different chemical compositions. To finalize the
comparison between LP and AP-PECVD, coatings have been processed on multicrystalline silicon solar cells.

description: SINGULUS TECHNOLOGIES AG presents the SINGULAR, a novel inline production tool prepared
for the future silicon-cell production. The central concept of SINGULAR is the static inline production (SIP) which
combines static processing and inline production. Processing small substrate lots allows compact tool footprint and
guarantees stable processes. An automatic inline chamber cleaning and the redundant modular setup ensure high
productivity. The first process established on the SINGULAR tool is an ICP-PECVD antireflection coating. In this
paper, we describe the concept of the SINGULAR production tool and the physical and chemical properties of the
deposited layers.

description: We present a methodology for the analysis and the evaluation of the electrical effects of partial shadings on
a PV array. This methodology is namely developed in a pedagogic tool of the software PVsyst, which aims to explain
how a shaded cell or group of cells behaves within a PV array. We use this tool for understanding the functions of the bypass
diodes, and quantify the array electrical losses in some typical situations, when one or several cells are shaded. We
show that the electrical shading effect is dependent either on the length of the strings, and on the number of strings in
parallel. This method should be applied for accurate shading calculations within the simulation process of PVsyst in a
near future.

description: We have performed a systematic variation of the wet chemical oxidation and the subsequent oxide etching
steps during the cleaning of Czochralski (CZ) single crystalline silicon wafers prior to surface passivation. The optimization
of these preconditioning steps was carried out on saw-damage etched or textured Si wafers subsequently passivated by amorphous
silicon nitride (a-SiNx:H) or chemical passivation by an iodine ethanol (I/E) solution. Measuring the carrier lifetime
using the spatially resolved microwave detected photoconductance decay, we monitored the impact of the wet-chemical surface
conditioning on the surface morphology and wafer base doping type. For damage etched surfaces in alkaline potassium
oxide solutions and passivated by iodine ethanol, an optimum surface passivation is obtained by omitting the last water rinse
(as used in the standard clean) and adding a hot water treatment as final step in the cleaning procedure. While this results was
found for both p-type and n-type wafers, suggesting that the passivation mechanism is based on the saturation of dangling
bonds, a strong dependence on the doping type was observed for the passivation by a-SiNx:H. Prior to passivation by
a-SiNx:H, the best preconditioning for n-type was achieved by adding a hot water treatment and subsequent etching of the
oxide by hydrofluoric acid (HF). For p-type however, no improvement was achieved with respect to the standard cleaning
step. This dependency on the base doping type could be attributed to the passivation mechanism of a-SiNx:H based on the
field effect. By employing ammonium fluoride as final etching solution instead HF, followed by hot water treatment, compared
to the standard treatment, an improvement of the lifetime can be observed for both surface structures, indicating that
the surface micro-roughness can be reduced and the contamination can be removed.

description: This paper describes a stack of hydrogenated amorphous silicon (a-Si:H) and hydrogenated amorphous silicon nitride
(a-SiNx:H) which was developed and characterized with the aim to obtain a firing stable passivation layer. A surface
recombination velocity below 40cm s-1 has been obtained after a firing step at 820°C, on highly doped p-type Float
Zone (FZ) crystalline silicon wafers. Fourier Transform InfraRed (FTIR) spectroscopy measurements showed that most
of the silicon hydrogen bounds (SiH) in the a-Si:H layer are lost after firing independently of the firing stability of the
passivation. Capacitance-Voltage (CV) measurements showed that the a-Si:H layer assumed to be intrinsic is, in fact,
doped n-type. The measured doping of the layer might result in a field-effect passivation on lowly doped p-type silicon
surfaces. However, significant shunt losses can be expected when the stack of layers is applied for rear surface
passivation on p-type silicon solar cells.

lower than those of conventional electricity.

description: It is not always possible to prevent dormers, chimneys, or trees from casting their shadows on PV plants.
However, in order not to jeopardize the economic viability of a PV plant, the yield losses due to shading must be
minimized already in the phase of system planning. Influential factors such as the arrangement of the PV modules, their
connection, and in particular the choice of the right PV inverter play an important role. By observing some important
design rules, these factors can be adapted to the PV plant so that their energy supply can be used almost completely.
This text demonstrates the effects of shade on a PV plant and derives from them recommendations for the right design of
the plant to minimize the losses in energy yield.

description: Low pressure chemical vapour deposition (LP-CVD) of ZnO is one of the best methods to produce thin
transparent conductive oxide (TCO) layers for amorphous and microcrystalline silicon solar cells. ZnO layers deposited by
the LP-CVD method bring many advantages, including easily tuneable deposition processes to production needs and
independence from suppliers of SnO2 TCO glasses. Light scattering of as grown LP-CVD ZnO layers is an important factor
in improving tandem (micromorph) silicon modules. This paper describes physical properties of ZnO layers grown on a
large scale (1300´1100 mm2). All experiments were done on OC Oerlikon TCO 1200 LP-CVD system, which is the first
mass production tool for manufacturing of TCO layers with the adjustable Light Trappingä process on 1.4 m2 substrates.
Currently achieved values for sheet resistance, transmittance and carrier concentration by variable process parameters are
shown. Light scattering of ZnO LP-CVD films is analyzed with an angle resolved scattering equipment.

description: A highly productive inline deposition system called “line source” is used to deposit amorphous and microcrystalline silicon single layers and pin- solar cells. The most important features of this deposition system are the linear plasma sources with a width of 500mm operated at an excitation frequency of 81.36 MHz in combination with moving substrates. A very homogeneous deposition of thin film silicon layers with layer thickness variations of less than +/- 5% was achieved. Amorphous and microcrystalline silicon single junction solar cells were dynamically fabricated with initial efficiencies of 8.3% and 5.2%, respectively. The dynamic deposition rate of these solar cells is 6.75nm.m/min in case of a-Si:H and 2.63nm.m/min for μc-Si:H. The amorphous silicon solar cells show a relative degradation of the initial efficiency of 29% while microcrystalline silicon cells only degrade about 6%. In this work it will be shown that an enhancement of the deposition rate during the i-layer deposition of a-Si:H solar cells has only a weak negative influence on the initial efficiencies of the cells. Further on, the effect of the substrate velocity on the solar cell characteristics of a-Si:H solar cells is investigated. Finally, a productivity estimation of the line source concept is presented. The influence of characteristic line source parameters like substrate velocity or electrode width on the estimated solar power production per year is discussed.

description: Dye-sensitized solar cells (DSSC) based on nanocrystalline TiO2 films have attracted much attention as
a potential low-cost alternative for commercial solar cells. Nanostructured TiO2 layers are commonly deposited with
screen printing or doctor blade technique. The aim of our study was to apply ink-jet printing for layer deposition
since it enables simple multiple depositions of the same pattern or spatial selectivity, therefore each layer in a
sequence can easily be made of different pattern. In the study inks based on Pechini method were realized by the
optimization of the molar ratio between the precursors in the sols. Ink-jet printed layers were used to assemble
DSSCs. The performance of solar cells were evaluated and compared with a standard TiO2 layers deposited with
doctor blade technique. Efficiencies up to 4.1 % were achieved when DSSCs with ink-jet printed TiO2 layers were
illuminated under STC.

for polymer-based solar cells. The embedded nano-electrodes allow three-dimensional conducting pathways for lowmobility
holes, offering a highly scaffolded cell architecture in addition to bulk heterojunctions. As a result, the
power conversion efficiency of a polymer cell with ITO nano-electrodes demonstrates an enhancement factor of up to
~10% and 36% under one-sun and five-sun illumination conditions, respectively, compared to a conventional cell.
Device lifetime also increases two-fold under five-sun illumination, showing great promise to enable concentrator
applications for polymer-based solar cells.

description: In this paper, we study entropic uncertainty relations on a finite-dimensional Hilbert space and provide several tighter bounds for multi-measurements, with some of them also valid for Rényi and Tsallis entropies besides the Shannon entropy. We employ majorization theory and actions of the symmetric group to obtain an {\it admixture bound} for entropic uncertainty relations for multi-measurements. Comparisons among all bounds for multi-measurements are shown in figures in our favor.

description: High quality doped ZnO as a window material could play an important role in amorphous and nanocrystalline
solar cell applications. In this work, we report on textured ZnO thin films deposited by reactive-environment hollow cathode
sputtering (RE-HCS), which have superior optical and electrical properties. The films are intended for use as a glass/TCO
superstrate for a-Si or hybrid a-Si/nc-Si thin-film solar modules. The overall process avoids a wet-etching step and doesn’t
need an expensive compound or alloy target, which makes it possible to manufacture solar cells in a clean and economic
way. The doped, textured ZnO thin-films are deposited by sputtering from a 50cm long hollow cathode fitted with two zinc
targets (with provision of oxygen as a reactive gas) onto a soda lime glass substrate which is at a temperature in the range of
180ºC to 330ºC. We have recently achieved the high mobility of 49.5cm2/Vs at a carrier concentration of 4.42 x 1020/cm3 as
determined by Hall effect measurements. This corresponds to a low film resistivity of 2.86 x 10-4 Ω.cm. High carrier
mobility is needed to avoid free carrier absorption in the near infrared range while retaining a low resistivity. The
morphology of the ZnO films can be controlled by deposition conditions such as pressure, reactive species, substrate
temperature, and bias. The dynamic deposition rate is 23nm.m/min at 3kW power and the film uniformity is about ±10%
over a width of 43cm. The efficiency of the single-junction a-Si solar cells made using these films as TCO on glass
increased about 8% comparing to the efficiency of the cells made on commercial SnO2. From this study, we demonstrate
that large area, high quality, textured, and cost-effective ZnO films can be achieved by the RE-HCS process, and the films
can be successfully used in device fabrication.

description: We report time-of-flight measurements on electrons travelling in quantum-Hall edge states. Hot-electron wave packets are emitted one per cycle into edge states formed along a depleted sample boundary. The electron arrival time is detected by driving a detector barrier with a square wave that acts as a shutter. By adding an extra path using a deflection barrier, we measure a delay in the arrival time, from which the edge-state velocity $v$ is deduced. We find that $v$ follows $1/B$ dependence, in good agreement with the $\vec{E} \times \vec{B}$ drift. The edge potential is estimated from the energy-dependence of $v$ using a harmonic approximation.

description: This dissertation introduces an adaptive Markov chain Monte Carlo technique called Bayesian Adaptive Independence Sampling with Latent variables (BAIS+L). BAIS+L, which extends an earlier technique known as Bayesian Adaptive Independence Sampling, has been designed with multimodal target distributions in mind. The dissertation discusses the development of BAIS+L, including an approximation that makes it possible, before assessing its performance through a comparison to the Equi-Energy Sampler and an application to spin glass simulation. It finishes with a discussion of a modification of BAIS+L, which avoids the use of the approximation, at the expense of greater computational complexity.

description: Scope: The purpose of this study is to understand the new trend of the day, influencer marketing and the impact that social media influencers have on online consumer behaviour. More specifically, the relationship between influencers and their followers, purchase intention and the degree of brand loyalty of the products or services they promote are analyzed. The basic approach is the theory of consumer behaviour, the potential purchase decision, while a conceptual framework has been developed to guide the study. Methodology: Our study utilized a quantitative approach, adopting an inductive approach, as it is based on an overall thematic approach, that of influencer marketing, by attempting a field research on its more specific themes. More specifically, a structured questionnaire with closed-ended questions was put together, to which 132 participants responded. The questions asked were based on the existing literature and the wealth of different research questions identified in the international literature.

description: We consider the two-line fitting problem. True points lie on two straight lines and are observed with Gaussian perturbations. For each observed point, it is not known on which line the corresponding true point lies. The parameters of the lines are estimated. This model is a restriction of the conic section fitting model because a couple of two lines is a degenerate conic section. The following estimators are constructed: two projections of the adjusted least squares estimator in the conic section fitting model, orthogonal regression estimator, parametric maximum likelihood estimator in the Gaussian model, and regular best asymptotically normal moment estimator. The conditions for the consistency and asymptotic normality of the projections of the adjusted least squares estimator are provided. All the estimators constructed in the paper are equivariant. The estimators are compared numerically.

description: The modulation of energy metabolism is a crucial mechanism to adapt to climate. This thesis highlights that genetic and climatic factors interact to shape metabolic responses. I used an integrative approach to study the metabolic activity of cells and the whole organism in wild populations of a native Australian songbird. I showed that metabolism was strongly affected by the presence of water in the environment and the genetic variation encoded in the mitochondrial genome. These drivers of climate adaptation have rarely been highlighted, but should be considered to conserve species more effectively under climate change.

description: The uncertainty principle is a cornerstone of modern physics, and its implications have a fundamental impact on theoretical and applied quantum mechanics. The aim of this thesis is to study and apply the uncertainty relations between time and energy, which are interpreted operationally as the speed limit of quantum evolution. A geometric approach is used to derive improved bounds for the evolution of isolated and open systems and obtain a constructive approach for efficient and fast quantum driving. These results are applied to set the limits for the rate of information transfer and processing, and the power of nanomachines.

description: DSC Modules were developed using the meander and integrated series connection design with the
glass frit sealing technique [1]. Optimised TiO2 screen printing in combination with a high extinction coefficient dye
C101 and different nitrile-solvent based electrolytes were tested for their performance in the modules. The platinized
counter electrodes showed a strong dependence on the electrolyte used. We examined several measurement
techniques usually applied in the characterisation of photovoltaic modules. Methods in particular have been electrical
impedance spectroscopy and the determination of the photovoltage decay. These methods are shown to be valuable
tools for examining the resistances in the modules.

description: According to the recent demands in the photovoltaic (PV) sector and anticipating future needs, this paper
analyzes and compares the Life Cycle Assessment (LCA) of four different technologies of PV panels: (monocrystalline,
polycrystalline, amorphous silicon and CIS modules).The paper’s scope also covers the calculation of the “Energy Pay
Back Time” (EPBT) of each of them, which involves the calculation of their embodied energy as well as their energy
production. Studying the embodied energy of each PV module enables to understand the influence of the different
recycling processes in the EPBT and LCA of each technology.
In the paper there are included the existing recycling and waste management processes for each type of module. This is
expected to be an important need in the near future when the end-of-life of PV plants approaches.

description: We developed a modular simulation program for detailed analysis of row shading at PV power plants.
The program is very flexible and new components like modules or inverters could be added easily. At first we
determine the direct and diffuse fraction of the irradiation as well as the temperature for each cell in the module with
the software Meteonorm. Then single cells are connected to an entire module and the modules are connected to
strings. Lastly the strings are connected to the inverter which delivers the output power. For the simulation of the I-V
curves we use an improved two diode model with an extension term for the negative voltage range.
The simulation of shaded modules with our improved two diode model shows a high level of agreement with the
measurements. The simulation of a whole PV system also shows reasonable agreement. The majority of the
remaining differences can be traced back to the irradiation time series which represents a typical year, the ratio of the
diffuse and direct fraction and the model for the calculation of the diffuse fraction in Meteonorm.
However, we have shown that our program could widely reproduce the losses for PV power plants without any
knowledge of the measured irradiation at the site.
‘I belong here but I’m not anchored here’: Ethnic identity construction and belongingness among multi-generation Australian-born Chinese

description: Chineseness is a multi-dimensional concept that is fluid and dynamic. Using a social constructivist approach, this thesis examined the construction of ethnic identity among Australian-born Chinese. The findings suggest that being Chinese is no longer solely determined by how one looks or what language one speaks. It also means different things to different people. And how one perceives themselves is not always aligned to how others perceive them.
