description: The monitoring of the chemical solutions is important for high efficiency cell processing. In solar cell
industry, the possible contamination of wet chemical bathes for texturing and cleaning with trace impurities is not yet
studied intensively. Questions concerning the desired bath purity or the maximum impurity load of the cleaning bath
can only be answered empirically. This paper gives an overview of possible measurement techniques and tools for
qualification of the cleaned surface itself as well as for controlling the relevant impurities in the cleaning solutions.
Atomabsorption spectrometry and emission spectrometry to analyse impurities in wet chemical solutions are described.
The correlation between metal impurities and the lifetime are shown.

description: We consider the model averaged tail area (MATA) confidence interval proposed by Turek and Fletcher, CSDA, 2012, in the simple situation in which we average over two nested linear regression models. We prove that the MATA for any reasonable weight function belongs to the class of confidence intervals defined by Kabaila and Giri, JSPI, 2009. Each confidence interval in this class is specified by two functions b and s. Kabaila and Giri show how to compute these functions so as to optimize these intervals in terms of satisfying the coverage constraint and minimizing the expected length for the simpler model, while ensuring that the expected length has desirable properties for the full model. These Kabaila and Giri "optimized" intervals provide an upper bound on the performance of the MATA for an arbitrary weight function. This fact is used to evaluate the MATA for a broad class of weights based on exponentiating a criterion related to Mallows' C_P. Our results show that, while far from ideal, this MATA performs surprisingly well, provided that we choose a member of this class that does not put too much weight on the simpler model.

description: Understanding the relation between planned and realized flight trajectories and the determinants of flight deviations is of great importance in air traffic management. In this paper we perform an in depth investigation of the statistical properties of planned and realized air traffic on the German airspace during a 28 day periods, corresponding to an AIRAC cycle. We find that realized trajectories are on average shorter than planned ones and this effect is stronger during night-time than daytime. Flights are more frequently deviated close to the departure airport and at a relatively large angle to destination. Moreover, the probability of a deviation is higher in low traffic phases. All these evidences indicate that deviations are mostly used by controllers to give directs to flights when traffic conditions allow it. Finally we introduce a new metric, termed difork, which is able to characterize navigation points according to the likelihood that a deviation occurs there. Difork allows to identify in a statistically rigorous way navigation point pairs where deviations are more (less) frequent than expected under a null hypothesis of randomness that takes into account the heterogeneity of the navigation points. Such pairs can therefore be seen as sources of flexibility (stability) of controllers traffic management while conjugating safety and efficiency.

description: This study investigates the compensation effects at iso-carrier density on two intentionally compensated
multicrystalline ingots grown from Solar-Grade Silicon feedstocks purified using metallurgical routes. The effects of the
dopant compensation on both ingots were studied at the wafer and the solar cell levels at given equilibrium carrier
densities, in order to allow a relevant investigation of the compensation effects on the overall electrical properties. At the
wafer level the majority carrier mobility and the carrier lifetime were investigated. At the cell level, I-V characteristics
under standard illumination were studied. In the light of all the characterization results, we propose physical mechanisms
that explain the iso-carrier density differences in electrical properties observed between the two ingots.

description: Upgraded metallurgical (umg-) silicon has become an alternative feedstock material for silicon solar
cells and may offer a cost advantage over the conventional silicon feedstock produced by the Siemens process. One
problem of these materials is the higher concentration both of boron and phosphorus. Due to the different segregation
coefficients the impurities are enriched differently during crystal growth towards the end of the crystallization. In
industrial production it is necessary to know the concentrations of these dopants so that the growth process can be
controlled. The paper presents two methods to determine the dopant concentrations. First it is shown that in umgsilicon
the boron concentration could be measured by FT-IR spectroscopy at room temperature by the local vibration
modes of boron at 620 cm-1 and 644 cm-1. Together with the carrier concentration, which was determined from the
absorption coefficient at 400 cm-1, the concentration of phosphorus can also be determined. Secondly, Hall and
resistivity measurements are carried out to determine the carrier concentration and mobility. The results are analyzed
to determine the boron and phosphorus concentrations along the growth direction.

description: This thesis examines whether shipowners can be held liable under current international law for harm caused by exposure to asbestos during ship recycling. After analysing three possible international conventions, this thesis concludes that it is legally possible to successfully enable attribution of liability to ship owners under the Basel Convention. It provides a justification for attributing liability, provides a generally applicable international law definition of the term ‘ship’, provides methods to identify when a ship becomes waste in any given scenario, and demonstrates how the State of Export can be identified when enforcing the Basel Convention.

description: In order to achieve faster time to market for new innovations and to optimize existing
manufacturing processes it is becoming increasingly important to develop models that allow for the design
and optimization of new cells and modules. In this article a thermo-mechanical bowing model of a solar cell
after firing is described. The model integrates the thermo-mechanical behaviour of the layers at the rear of
the cell to allow bowing of the cell to be predicted. Most commercially manufactured solar cells consist,
apart from a p-type silicon bulk, of a number of layers: silver, silicon-nitride, BSF and rear-side aluminium.
The silicon, silver, silicon-nitride, BSF and eutectic Al-silicon rear-side layers can be accurately described
using standard modelling techniques. The Al bulk layer can best be modelled as a composite material. A
Mori-Tanaka homogenisation method was used in combination with detailed finite element models of the Al
microstructure to predict the mechanical response of the Al layer. This composite modelling approach
allows the mechanics of the Al microstructure to be related to the effect of Al on cell bowing. Microstructural
features include morphology, inclusion size, aspect ratio distribution and mechanical properties of the
inclusions in the Al layer. The model can also be used to predict the Al microstructure based on
measurements of cell bowing. Furthermore it is shown that when plastic behaviour is incorporated that final
bowing is determined by the flow stress and hardening behaviour of the eutectic and Al bulk layer. The
Young’s modulii of the eutectic and Al bulk layer, thermal expansion coefficients and temperature change
during the firing process do not directly affect final bowing.

description: Moisture ingress into a photovoltaic module accelerates the degradation phenomena in different ways [1-3]. Polymeric components of photovoltaic modules are sensitive to moisture, due to hydrolysis reactions which can cause changes in their chemical structure and therefore in their properties. Hydrolysis of EVA leads to the formation of acetic acid, which accelerates the corrosion reactions of metallic parts of the circuit. PET hydrolysis is also an undesirable process caused by the presence of water inside the module. In addition, moisture ingress will reduce the adhesion between glass and EVA. This work is focused on investigating the behaviour in terms of moisture ingress of some new backsheets that have recently appeared in the PV market due to the shortage of Tedlar®. After a market survey, suitable humidity sensors have been selected and used to quantify the humidity content inside the module while it is being exposed to damp heat conditions. Gravimetric measurements have also been carried out to evaluate the water vapour ingress rates at different exposure times to various conditions of temperature and relative humidity.

description: The most important technical criterion for the future development of the photovoltaic technology is the quality of the PV modules. Quality strongly influences a module’s ability to withstand rough climate conditions during
prolonged outdoor exposure. Quality standards are determined by the design qualification and type approval according to IEC 61215. arsenal research has been accredited for this standard since 2003. Based on the testing activities, a database has been developed and is extending continuously. This database contains information about module components and their specifications, different steps of production processes as specified by manufacturers and detailed tests results. The database represents a powerful tool to evaluate the enormous quantity of information obtained from the qualification testing. First results show that failures during the IEC testing were mainly due to processing issues rather than applying wrong components.
Mechanisms Regulating Immune Checkpoint Inhibitor PD-L2 Expression in Melanoma

subject: Other education not elsewhere classified

description: Immune checkpoint inhibitors that target the programmed cell death receptor-1 (PD1) have significantly improved the survival of patients with advanced melanoma. Signalling through the PD1 receptor upon binding to its cognate ligands PD-L1 and PD-L2 suppresses T cell activity and dampens anti-tumour immune responses. Both PD-L1 and PD-L2 are expressed on melanoma cells, and this contributes to tumour evasion from the immune system. The regulation of PD-L1 expression in melanoma is well described, but much less is known about the mechanisms regulating PD-L2 expression. Interestingly, PD-L2 is highly expressed in dedifferentiated melanomas, a phenotypic subset of melanoma cells highly resistant to immune checkpoint inhibitors. In this thesis, we investigated the expression of PD-L2, at the transcript and protein level, in a small panel of melanoma cell lines with distinct differentiation status. We explored the effects of cytokine exposure, hypomethylation and oncogenic pathway inhibition on PD-L2 expression in melanoma. We show that the cytokines TNFα and IFNγ induce PD-L2 expression in both melanocytic and dedifferentiated melanoma phenotypes. However, basal expression of PD-L2 is cell-type specific and partially dependent on tumour-intrinsic Src and FAK signalling. Our results indicate that PD-L2 is regulated independently of PD-L1, and differences in response to cytokine induction, the epigenetic methylation status, and constitutive oncogenic pathway signalling may reflect basal differences in PD-L2 expression between distinct melanoma phenotypes.

description: This thesis investigates who trafficks drugs into Australia, how these persons are sentenced, and whether their sentences are consistent with international human rights norms. It is contended that the international human rights doctrine of constitutional proportionality is the appropriate test for making this evaluation because of its widespread use in constitutional and human rights adjudication, including by the European Court of Human Rights and the United Nations Human Rights Committee. Based on sentencing remarks from a sample of 94 cases, the results reveal systemic problems with sentence formulation which produce disproportionate sentences, contrary to international human rights norms.

description: A tracking system that will be used for Augmented Reality (AR) applications has two main requirements: accuracy and frame rate. The first requirement is related to the performance of the pose estimation algorithm and how accurately the tracking system can find the position and orientation of the user in the environment. Accuracy problems of current tracking devices, considering that they are low-cost devices, cause static errors during this motion estimation process. The second requirement is related to dynamic errors (the end-to-end system delay; occurring because of the delay in estimating the motion of the user and displaying images based on this estimate. This paper investigates combining the vision-based estimates with measurements from other sensors, GPS and IMU, in order to improve the tracking accuracy in outdoor environments. The idea of using Fuzzy Adaptive Multiple Models (FAMM) was investigated using a novel fuzzy rule-based approach to decide on the model that results in improved accuracy and faster convergence for the fusion filter. Results show that the developed tracking system is more accurate than a conventional GPS-IMU fusion approach due to additional estimates from a camera and fuzzy motion models. The paper also presents an application in cultural heritage context.

description: In the family of the iron-based superconductors, the $RE$FeAsO-type compounds (with $RE$ being a rare-earth metal) exhibit the highest bulk superconducting transition temperatures ($T_{\mathrm{c}}$) up to $55\ \textrm{K}$ and thus hold the key to the elusive pairing mechanism. Recently, it has been demonstrated that the intrinsic electronic structure of SmFe$_{0.92}$Co$_{0.08}$AsO ($T_{\mathrm{c}}=18\ \textrm{K}$) is highly nontrivial and consists of multiple band-edge singularities in close proximity to the Fermi level. However, it remains unclear whether these singularities are generic to the $RE$FeAsO-type materials and if so, whether their exact topology is responsible for the aforementioned record $T_{\mathrm{c}}$. In this work, we use angle-resolved photoemission spectroscopy (ARPES) to investigate the inherent electronic structure of the NdFeAsO$_{0.6}$F$_{0.4}$ compound with a twice higher $T_{\mathrm{c}}=38\ \textrm{K}$. We find a similarly singular Fermi surface and further demonstrate that the dramatic enhancement of superconductivity in this compound correlates closely with the fine-tuning of one of the band-edge singularities to within a fraction of the superconducting energy gap $Δ$ below the Fermi level. Our results provide compelling evidence that the band-structure singularities near the Fermi level in the iron-based superconductors must be explicitly accounted for in any attempt to understand the mechanism of superconducting pairing in these materials.

description: In the current photovoltaic market, the importance of module quality control process is growing although its implementation in large size plants is not evident and it can also produces delays in the setting up of the power plant. In this article, the authors describe a simple module testing process aimed to be applied in the field. It allows more than 1MW per day testing rate and a repeatability better than 1,5%. The process has been tested in the facilities of the Instituto de Energía Solar of the Universidad Politécnica de Madrid, and it has been applied in the field in a 12 MW photovoltaic plant in Spain. The results show different values from what was expected if attending to manufacturer data, in particular a higher dispersion in power values. This make the authors think that classifying the modules on the basis of their flash-report power has no relevance.

description: Number of large photovoltaic plants (several MW each one) grid-connected in Spain is growing exponentially. IES-UPM has developed a testing protocol for the quality assurance of PV plants which includes testing of PV arrays with a self-made capacitive load. This equipment can measure PV arrays of 100 kWp and over (voltages up to 900 V and currents up to 400 A), just at once without the requirement of separating them into smaller ones. This paper reports results of these measurements of PV arrays from 5 kWp to 130 kWp, and shows the reality of systems which are being installed in Spain.

description: For the construction of solar modules, the reverse characteristic of the employed solar cells is
important. Diode breakdown in shaded cells can lead to hot spot development which can destroy the cell
encapsulation and thus seriously damage the module. We investigated the breakdown behaviour of multicrystalline
silicon solar cells. Three breakdown types are discerned: (i) Early pre-breakdown, (ii) soft breakdown related to
recombination-active regions and (iii) hard avalanche breakdown at etched dislocations. We give a summary of their
physical properties and their likely origin. Finally, we discuss the dangerousness of each breakdown type for solar
modules.

using 10 x 10 cm size wafers [1]. The ingots were grown by controlling the distribution and orientation of dendrite crystals
using the dendritic casting method. The conversion efficiency of solar cells using the Si wafers was around 17.7 %, and the
conversion efficiency was kept high and constant even in a large part (60% for more than =17% and 80% for more than
=16%) of the small ingot.

description: 25th European Photovoltaic Solar Energy Conference and Exhibition / 5th World Conference on Photovoltaic Energy Conversion, 6-10 September 2010, Valencia, Spain; 5141-5144
description: Building-integrated photovoltaics (BIPV) have seen an impressive development throughout the world this last
decade. In France, photovoltaic (PV) installations under 3 kWp represent 90% of the plants in service as of 2009, and count
for 42% of the national installed photovoltaic power [1]. Residential BIPV installations are not only characterized by there
relatively small peak power but also by their sensitivity to perturbed environmental conditions such as partial shading. Partial
shading of BIPV plants can be caused by several factors such as nearby trees, chimneys or buildings, consequently causing
PV module mismatch losses. Such losses are mainly due to the dispersion in electrical characteristics of interconnected
modules which leads to significant decrease in plant energy production. The introduction of additional power converters in
the plant layout intends to reduce the influence of one module on the entire installation, thus reducing module mismatch. In
this work, five grid-connected PV installation topologies: centralized inverter, string inverter, module inverter, parallel
connected choppers with centralized inverter, series connected choppers with centralized inverter are presented and
compared. Furthermore, average modelling of Boost DC-DC converters and grid-connected inverters with their associated
control strategies are proposed. Performance analysis of these topologies is carried out through normal operation and two
partially shaded scenarios representing chimney and nearby building induced shade. Simulations using the proposed average
models have been implemented in Matlab/Simulink© environment for each topology using a 3 kWp rooftop-type plant.
Simulation results show that a considerable amount of additional solar generated energy can be grid-fed using alternative
plant layouts.

description: We show the possibility of long-range ferrimagnetic ordering with a saturation magnetisation of the order of 1 Bohr magneton per spin for arbitrarily low concentration of magnetic impurities in semiconductors, provided that the impurities form a superstructure satisfying the conditions of the Lieb-Mattis theorem. Explicit examples of such superstructures are given for the wurtzite lattice, and the temperature of ferrimagnetic transition is estimated from a high-temperature expansion. Exact diagonalization studies show that small fragments of the structure exhibit enhanced magnetic response and isotropic superparamagnetism at low temperatures. A quantum transition in a high magnetic field is considered and similar superstructures in cubic semiconductors are discussed as well.

description: In anticipation of the Gaia astrometric mission, a large sample of spectroscopic binaries has been observed since 2010 with the SOPHIE spectrograph at the Haute--Provence Observatory. Our aim is to derive the orbital elements of double-lined spectroscopic binaries (SB2s) with an accuracy sufficient to finally obtain the masses of the components with relative errors as small as 1 % when the astrometric measurements of Gaia are taken into account. In this paper we present the results from five years of observations of 10 SB2 systems with periods ranging from 37 to 881 days. Using the TODMOR algorithm we computed radial velocities from the spectra, and then derived the orbital elements of these binary systems. The minimum masses of the components are then obtained with an accuracy better than 1.2 % for the ten binaries. Combining the radial velocities with existing interferometric measurements, we derived the masses of the primary and secondary components of HIP 87895 with an accuracy of 0.98 % and 1.2 % respectively.

description: Prior work has established that all problems in NP admit classical zero-knowledge proof systems, and under reasonable hardness assumptions for quantum computations, these proof systems can be made secure against quantum attacks. We prove a result representing a further quantum generalization of this fact, which is that every problem in the complexity class QMA has a quantum zero-knowledge proof system. More specifically, assuming the existence of an unconditionally binding and quantum computationally concealing commitment scheme, we prove that every problem in the complexity class QMA has a quantum interactive proof system that is zero-knowledge with respect to efficient quantum computations. Our QMA proof system is sound against arbitrary quantum provers, but only requires an honest prover to perform polynomial-time quantum computations, provided that it holds a quantum witness for a given instance of the QMA problem under consideration. The proof system relies on a new variant of the QMA-complete local Hamiltonian problem in which the local terms are described by Clifford operations and standard basis measurements. We believe that the QMA-completeness of this problem may have other uses in quantum complexity.

economically viable will be described: using hybrid photovoltaic/thermal (PV/T) solar systems. This has two main
advantages: preheated feed water leads to significantly higher fresh water output as RO membrane recovery ratio
highly depends on the feed water temperature. Meanwhile, the PV module is cooled resulting in higher electrical
efficiency and consequently a higher water output. A simulation for estimating the potential of this combination was
performed. It will be shown that PV/T driven plants produce about 30% to 40% more potable water than PV driven
plants. Compared to a pure RO-PV system, 20% to 30% of collector area could be saved. However, only a small
cooling effect of the fluid can be observed. Furthermore, it will turn out that PV/T systems can also be an economic
alternative to pressure recovery systems, which, up to now, are only feasible in large-scale desalination plants.

description: A novel photovoltaic off-grid system concept has to be designed to power rural and remote schools according to the
technical and economic specifications of the new distance education programme in Mexico. Rural and far-flung
communities, from which more than 100,000 have less than 100 inhabitants, are scattered in vast distances with very
difficult access. The challenge for PV off-grid systems is to operate in such a way that mainly enhances: 1) a longer
life for the PV system and system components, 2) a good performance ratio, and 3) to be free of faults as much as
possible. Additionally, where diesel engines are operated, PV systems may also contribute to the substitution of the
diesel engines and to the reduction of fossil fuel consumption.
Besides electricity supply standards, the integration of communication technologies will contribute to the success of
the distance education programs. Bi-directional delivery of information will allow for academic and cultural
exchange. On-line consultation and school will contribute at the same time for the monitoring of the PV systems in
order to guarantee the well functioning, to prevent failures and to provide spare parts in the case of break downs or
others.
Children in cars: The role of in-vehicle behaviour in child occupant protection
Creators: name: SUZANNE LEE CROSS
Publisher: name: Monash University

Subjects: Applied Psychology

description: Aims were to examine what parents say, think and believe about child restraint system (CRS) use and child travel safety, and how children were restrained and behaving in their CRS during every-day car trips. The research comprised three stages. Stage 1 used an online survey to explore parental beliefs about CRS use and child occupant safety. Stages 2 and 3 used a naturalistic driving study. Stage 2 identified characteristics of child occupant travel. Stage 3 identified the travel characteristics (familial-, child-, trip-related) associated with suboptimal head positions for child occupants when travelling in a forward-facing CRS or a booster seat.

description: 23rd European Photovoltaic Solar Energy Conference and Exhibition, 1-5 September 2008, Valencia, Spain; 2805-2807
description: In practical applications, photovoltaic modules are wired together into electrical circuits or an array to provide the necessary voltage and/or current outputs. In several research works, it has been reported that array performances depend greatly on the variability of the modules that comprise the array and solar cells forming the PV modules [1-2]. The difference between the maximum output power available from the array and the sum of the maximum output power for each of the modules is known as the mismatch losses. The purpose of this work is to present experimental and modelling results on the mismatch effects of PV modules, with an especial attention to the generation losses due to this effect.
Exactly solvable dynamical models with a minimal length uncertainty

description: We present exact analytical solutions to the classical equations of motion and analyze the dynamical consequences of the existence of a minimal length for the free particle, particle in a linear potential, anti-symmetric constant force oscillator, harmonic oscillator, vertical harmonic oscillator, linear diatomic chain, and linear triatomic chain. It turns out that a minimal length increases the speed of a free particle and the rate of fall of a particle that is subject to the influence of a linear potential. Our results suggest that the characteristic frequency of systems tend to increase when there is a minimal length. This is a common feature that we observed for the oscillator systems that we have considered.

description: 24th European Photovoltaic Solar Energy Conference, 21-25 September 2009, Hamburg, Germany; 883-885
description: A short while ago the availability of silicon feedstock seemed to be the main factor limiting the
photovoltaic industry. But changes in the market like the global economic recession accompanied by the financial
crisis and the decision of Spain to change its feed-in-tariff policies very fast showed that there are demand limits.
Some consultants had to revise their forecasts regarding demand, price and profits significantly for the whole
industry. In the changed situation it turns out that PV based on crystalline Silicon can compete very well with
alternative PV technologies. It is also proven that quality and performance only in times of shortage are subjects of
discussion and compromises. Excellent polysilicon quality is a stable base for lower total cost of ownership
throughout the PV value chain.

description: A novel ion beam-induced cleaving process for slicing mono-crystalline silicon wafers ranging in thickness
from 20μm to 150μm with near zero kerf-loss and markedly low overall cost has been developed. The process was recently
demonstrated to be capable of large-area thin PV substrate manufacturing with excellent conversion efficiency and low
polysilicon use. Usability of the wafers in next-generation high-efficiency PV cell manufacturing is further enhanced by its
excellent surface roughness, edge quality, mechanical strength and carrier lifetime. A practical production line equipment
concept for high-volume manufacturing using this kerf-free layer-transfer technology is introduced. The extension of the
process to novel 20μm and substitutive 150μm wafering is also described.
Is the World Local or Nonlocal? Towards an Emergent Quantum Mechanics in the 21st Century

description: What defines an emergent quantum mechanics (EmQM)? Can new insight be advanced into the nature of quantum nonlocality by seeking new links between quantum and emergent phenomena as described by self-organization, complexity, or emergence theory? Could the development of a future EmQM lead to a unified, relational image of the cosmos? One key motivation for adopting the concept of emergence in relation to quantum theory concerns the persistent failure in standard physics to unify the two pillars in the foundations of physics: quantum theory and general relativity theory (GRT). The total contradiction in the foundational, metaphysical assumptions that define orthodox quantum theory versus GRT might render inter-theoretic unification impossible. On the one hand, indeterminism and non-causality define orthodox quantum mechanics, and, on the other hand, GRT is governed by causality and determinism. How could these two metaphysically-contradictory theories ever be reconciled? The present work argues that metaphysical contradiction necessarily implies physical contradiction. The contradictions are essentially responsible also for the measurement problem in quantum mechanics. A common foundation may be needed for overcoming the contradictions between the two foundational theories. The concept of emergence, and the development of an EmQM, might help advance a common foundation - physical and metaphysical - as required for successful inter-theory unification.

description: Over the past ten years the Photovoltaic (PV) Industry has seen unprecedented growth and PVinstallations
world-wide have grown from 250 MWp in 2000 to ca. 7800 MWp in the year 2009. More than 80%
of module production in 2010 with estimated installation of 10000 MWp is based on crystalline silicon wafer
technology. The paper analyses the availability of solar-grade silicon and gives an overview of multicrystalline
and monocrystalline silicon ingot and wafer technology. In addition, the paper examines this technology in the
context of a growth scenario worked out by the European Photovoltaic Industry Association (EPIA) that would
lead to 12% Solar Electricity in Europe and world-wide of approx. 5% by 2020. Emphasis is placed on further
cost reduction potential of the dominant c-Si technology for ingot production – directional solidification and
Czochralski technique – and wire saw technology for wafering. The importance of economic material usage and
recycling is stressed when continuing along the described high growth scenarios towards 2020.
