description: In this paper we come back to a problem proposed by F. Hirzebruch in the 1980's, namely whether there exists a configuration of smooth conics in the complex projective plane such that the associated desingularization of the Kummer extension is a ball quotient. We extend our considerations to the so-called $d$-configurations of curves on the projective plane and we show that in most cases for a given configuration the associated desingularization of the Kummer extension is not a ball quotient. Moreover, we provide improved versions of Hirzebruch-type inequality for $d$-configurations. Finally, we show that the so-called characteristic numbers (or $γ$ numbers) for $d$-configurations are bounded from above by $8/3$. At the end of the paper we give some examples of surfaces constructed via Kummer extensions branched along conic configurations.

description: The HSUN® is a medium Concentrated Photovoltaic (CPV) system based on reflective optics, with a
concentration of 20 suns, under development by WS Energia S.A.
In this paper a new method to achieve experimental advances in the pre-certification process of a concentrator is
presented and applied to the HSUN®. The development of the proposed method is composed by two phases, the crash test
and the pre-certification. Each test has a pass/fail criterion. This compendium of accelerated tests is essential to predict
eventual failures during the certification process, in a time compressed way.
This paper provides an insight on CPV certification tests as preliminarily defined in the IEC 62108. As a result from the
performed tests, some improvements in design, soldering process and reinforcement of the mirrors support structure of
HSUN® were implemented before beginning the certification process.

description: This paper describes design and development of the Maximum Power Point Load (MPPL) - a standalone
MCU controlled module offering all the functionality needed for continuous measurement of photovoltaic
module I-V curve, MPP point, open circuit voltage and short circuit current. This module is a part of a complex
photovoltaic module efficiency measurement system which is currently being developed by the author. Experimental
photovoltaic panel is installed outside the laboratory. Measurement system consists of the solar radiation
measurement module (pyranometer), photovoltaic panel load module (MPPL described in this paper) and panel
climate measurement module (panel temperature and its distribution, air flow around the panel). Data from
measurement modules is being captured via control computer for subsequent analysis of panel efficiency and climatic
impacts on it.

description: With increasing cost pressure on all components of PV system increasing the DC/AC ratio is one possible
way to decrease specific inverter costs. To find the break even it is essential to know losses due to power and current
limitation depending on the DC/AC ratio. Thence simulation software is used for comparative analyses.
This study aims to analyse standard software tools in regard to the quality of the simulation of inverter losses in
general and overload losses in particular. It may be seen that mainly due to the simulation time step the uncertainty
clearly increases with higher DC/AC ratios. Further climatic conditions have a major impact on the simulation quality.

description: The knowledge of the majority carrier mobility in silicon as a function of dopant density is of
utmost importance for a correct quantitative evaluation of a variety of lifetime measurements. However, only for
monocrystalline silicon doped with either boron (concentration NA) or phosphorus (concentration ND), sufficient
reliable experimental data exists as well as good models. In the presence of both dopants, in so called
compensated silicon, a reduced mobility is expected. It seems that the model of Klaassen provides acceptable
values for the mobility in lowly compensated monocrystalline silicon as a function of NA + ND [1]. For more
strongly compensated monocrystalline silicon and for multicrystalline silicon, it is not sure if this model is still
applicable. In this contribution, the conductivity mobility of majority carrier holes as well as the Hall mobility in
compensated and non-compensated multicrystalline (mc) p-type silicon is investigated and compared with the
established mobility models as well as with the data from monocrystalline silicon.

description: In warm periods the excess of incoming solar energy into a greenhouse is more than required for the growth of the crop. In particular the near infrared radiation (NIR) part of the incoming radiation is not necessarily. In a previous research project a new type of greenhouse with an integrated concentrated photovoltaic system with thermal energy output  (CPVT-system) was developed. This earlier system was based on a circular covering geometry and an integrated filter for reflecting the NIR of the greenhouse. The reflected  radiation was used in a solar energy system. In this feasibility study the new CPVT-system is simplified so more economically by avoiding the asymmetric greenhouse construction with bended glass and the large construction for solar tracking. All parts of the solar concentrating system will be mounted inside a standard Venlo type greenhouse. The concentrator consists of lamellae which only focus the NIR-part of the spectrum onto the CPVT–module. This module is mounted to or integrated into the ridge or gutter of the greenhouse. With this spectral selection  the heat load inside the greenhouse will be reduced. The target is a maximal total annual electricity production. The optimization is done with a ray tracing model fed with actual radiation data. Two types of lamellae are compared: flat lamellae and trough shaped lamellae which focus the radiation individually. Trough shaped lamellae have the advantage of reducing the number of lamellae in combination with a high concentration ratio. This will lower the costs for the servo drive of the lamellae. The reflected NIR radiation can be focused with a geometric concentration factor of 100x. The lamellae will not only reflect 49% of the NIR radiation but also a part of the whole solar spectrum. The total effective concentration ration factor will be 23x, including the transmission losses of the greenhouse and the efficiency of the concentrator. The high geometric concentration factor will limit the shadowing effect of the cultivation area by the PV-cells with only 1%. Further optimalisation in the energy yield were performed on determination of the optimal focal length of the trough shaped lamellae. The highest annual electrical output was found for lamellae with individual optimized focal lengths. In that case the annual output for Dutch climate conditions can be over 29 kWh/m².

description: Anodic oxidation is an electrochemical method for growing precise films of oxide driven by an applied bias
voltage. The oxide thickness is related to the applied bias while the growth rate is limited by the oxide thickness leading to a
very uniform and easily controlled process. Here the oxidation is used to selectively etch back the dead layer of a heavily
doped emitter producing a selective emitter. 125mm square mc-Si selective emitter cells had improved Voc (5.6 mV) and Jsc
(0.66 mA.cm2) due to better surface passivation and blue response. The final average cell efficiency of the best selective
emitter group processed here was increase by ~0.3%abs to ~16.4%.

description: When sputtering aluminum doped zinc oxide from a ceramic target, the layer is damaged
perpendicular to the erosion area by high energetic oxygen ion bombardment [1]. The ions receive their energy from
the potential difference between cathode and floating substrate. Their impact leads to a higher resistivity and lower
mobility of the deposited layer. This counteracts the necessary properties of a TCO as front contact in a-Si/μc-Si
solar cells, where good transparency and conductivity is desired. To diminish the damaging effect of the oxygen
ions the use of stronger magnets for magnetron sputtering was examined. Static imprints with a standard and a
strong magnetron were performed by using a new plane ZnO:Al2O3 (1 wt.%) target. Thickness, resistivity, mobility,
carrier density, aluminum concentration and doping efficiency were determined. The results show a clear reduction
of target voltage by 40 V at the same applied power of 6 kW and also a loss of damage opposite to the race tracks.
Hereby resistivity was lowered by a factor of 1.5 and mobility was increased from 22.5 to 28.8 cm²/ Vs at the
position opposite to the race track. The new approach of using stronger magnets during sputtering was shown
regarding a planar target and can be applied at rotatable tube targets.

description: $1/f$ noise caused by microscopic Two-Level Systems (TLS) is known to be very detrimental to the performance of superconducting quantum devices but the nature of these TLS is still poorly understood. Recent experiments with superconducting resonators indicates that interaction between TLS in the oxide at the film-substrate interface is not negligible. Here we present data on the loss and $1/f$ frequency noise from two different Nb resonators with and without Pt capping and discuss what conclusions can be drawn regarding the properties of TLS in amorphous oxides. We also estimate the concentration and dipole moment of the TLS.

description: In the present note, we focus on certain properties of special curves that might be used in the theory of multi-point Seshadri constants for ample line bundles on the complex projective plane. In particular, we provide three Ein-Lazarsfeld-Xu-type lemmas for plane curves and a lower bound on the multi-point Seshadri constant of $\mathcal{O}_{\mathbb{P}^{2}}(1)$ under the assumption that the chosen points are not very general. In the second part, we focus on certain arrangements of points in the plane which are given by line arrangements. We show that in some cases the multi-point Seshadri constants of $\mathcal{O}_{\mathbb{P}^{2}}(1)$ centered at singular loci of line arrangements are computed by lines from the arrangement having some extremal properties.

description: To successfully compete with other photovoltaic technologies, amorphous silicon (aSi) based thin film
modules have to increase their efficiency, but still reduce production cost. For higher efficiency, stacked cells are
mandatory. For reducing cost, roll-to-roll deposition of flexible modules seems promising. This contribution
presents the in situ series connection (ISSC) to combine several advantages of thin film technology into one
manufacturing process. Successful wire patterning of aSi and ZnO proves the concept of ISSC for batch processing
and web coating. Depending on the particular layer stack of tandem cells containing amorphous as well as
microcrystalline doped silicon layers, the total loss F of ISSC ranges from F = 5 % to F = 12 %. An outlook on the
transfer of ISSC to industrial web coating concludes the paper.

description: This paper is concerned with the stochastic generalized Ginzburg-Landau equation driven by a multiplicative noise of jump type. By a prior estimate, weak convergence and monotonicity technique, we prove the existence and uniqueness of the solution of an initial-boundary value problem with homogeneous Dirichlet boundary condition. However, for the generalized Ginzburg-Landau equation, such a locally monotonic condition of the nonlinear term can not be satisfied in a straight way. For this, we utilize the characteristic structure of nonlinear term and refined analysis to overcome this gap.

description: We have studied the electronic properties of MBE-grown non-doped InGaAsN layers, lattice matched
to GaAs, with different nitrogen content. Our main emphasis is on the material characterization and especially on
testing the potential of Surface Photovoltage (SPV) measurements for the determination of the minority carrier
diffusion length in this material. Band gap narrowing due to added nitrogen was evaluated from room temperature
photoluminescence (RT-PL) spectra. The radiative recombination lifetime of minority carriers was measured by timeresolved
photoluminescence (TRPL). Both RT-PL and SPV results follow the general trend: as nitrogen content
increases the number of defects grows and the electronic quality of the material degrades. Experimentally obtained
parameters were used in p-i-n InGaAsN solar cell simulations performed with a Silvaco ATLAS device simulator.
The effect of nitrogen content in InGaAsN on the efficiency of the solar cell was estimated.

Convention on Elimination of Discrimination Against Women

description: Second semester University: Maastricht University.
description: “Gender-based violence against women is a widespread, grave and systematic human rights abuse that has remained significantly unaddressed by governments across the world”. Domestic violence is the most pervasive, insidious form of gender-based violence and it is still an ugly secret. Discrimination and structural inequality between women and men are the root causes. The State plays an important role in the struggle to combat domestic violence. Every State has an international obligation to respect, protect and fulfil women’s rights to be free from domestic violence. Insufficient State action is contributing to the universal phenomenon. This paper will provide an insight into the development of women’s rights in the international legal framework. There will be an analysis of the Convention on the Elimination of Discrimination Against Women and the Committee which monitors State compliance to this treaty. The numerous forms of gender-based violence will be unveiled with a focus on domestic violence. Ireland will be included as an example of insufficient State action regarding its international obligations to tackle domestic violence. Finally, recommendations will be made to effectively combat domestic violence and assist the victims.

attributed to the emitter stack. FF values above 80% are obtained through the use of a doped Buffer layer and ZnO

efficiency of 15.7% is reached on 25cm2 IBC Si-HJ structures with a FF value of 71.6%.

description: We consider any noncontextuality inequality, and the state preparation scheme which consists in performing any von Neumann measurement on any initial state. For an inequality which is not always satisfied, and Hilbert space dimensions greater than a value specified by the inequality, we determine necessary and sufficient conditions for the existence of observables with which the inequality is violated after the preparation process. For an initial state with no zero eigenvalues, there are always such observables, and which are independent of this state.

description: Within the EU funded project NACIR a concentrating photovoltaic (CPV) stand-alone system is
developed to provide electric power for water pumping, desalination and irrigation application. An energy
management system (EMS) is developed for a direct use of solar energy by the loads. Thus the system requires only
small sized battery storage to secure power supply only for measurement and control equipment as well as for the
motors of the trackers to orientate them in the morning or after a cloudy period during the day. For control and an
easy expansion of the system all components communicate via the standardized CANopen protocol. The first part of
this paper provides a description of the system layout and the developed EMS. The second part shows simulation
results of an optimized operating control strategy by transferring a solution of the packing problem from applied
economics to off grid systems. In the third part first field results of the 30 kWp CPV plant, installed at the test site of
the water research centre Wadi Al Netroun in Egypt, are presented.

description: Over the past few months, violence against women by the organisation Islamic State has been widely documented, along with the departure of western female migrants to ISheld territories. While the numbers are relatively insignificant, the media misrepresents the figures due to the nature of headline-grabbing stories about war crimes, especially against women, and for most of the population whose primary source of information about war is the media, these stories represent their closest contacts with war. This research adopts a gendered lens to understand the rationality of IS in its specific targeting of women, the highly gendered society it has implemented and in particular the different roles women can have during the conflict. While women are typically depicted as victims or monsters by the media and government agencies, this research attempts to demonstrate that women can find agency in various situations and at different degrees, from survival to extreme violence.

description: We discuss the determination of the $f_0(500)$ (or $σ$) resonance by analytic continuation through Padé approximants of the $ππ$-scattering amplitude from the physical region to the pole in the complex energy plane. The aim is to analyze the uncertainties of the method, having in view the fact that analytic continuation is an ill-posed problem in the sense of Hadamard. Using as input a class of admissible parameterizations of the scalar-isoscalar $ππ$ partial wave, which satisfy with great accuracy the same set of dispersive constraints, we find that the Roy-type integral representations lead to almost identical pole positions for all of them, while the predictions of the Padé approximants have a larger spread, being sensitive to features of the input parameterization that are not controlled by the dispersive constraints. Our conservative conclusion is that the $σ$-pole determination by Padé approximants is consistent with the prediction of Roy-type equations, but has an uncertainty almost a factor two larger.

description: This paper is devoted to study a class of nonlinear fractional Schrödinger equations: \begin{equation*} (-Δ)^{s}u+V(x)u=f(x,u), \quad \text{in}\: \mathbb{R}^{N}, \end{equation*} where $s\in (0,1)$, $\ N>2s$, $(-Δ)^{s}$ stands for the fractional Laplacian. First, by using a variational approach, we establish the existence of at least one nontrivial solution for the above equation with a general potential $V(x)$ which is allowed to be sign-changing and a sublinear nonlinearity $f(x,u)$. Next, by using variational methods and the Moser iteration technique, we prove the existence of infinitely many solutions with $V(x)$ is a nonnegative potential and the nonlinearity $f(x,u)$ is locally sublinear with respect to $u$.

description: When solving stochastic partial differential equations (SPDEs) driven by additive spatial white noise, the efficient sampling of white noise realizations can be challenging. Here, we present a new sampling technique that can be used to efficiently compute white noise samples in a finite element method and multilevel Monte Carlo (MLMC) setting. The key idea is to exploit the finite element matrix assembly procedure and factorize each local mass matrix independently, hence avoiding the factorization of a large matrix. Moreover, in a MLMC framework, the white noise samples must be coupled between subsequent levels. We show how our technique can be used to enforce this coupling even in the case of non-nested mesh hierarchies. We demonstrate the efficacy of our method with numerical experiments. We observe optimal convergence rates for the finite element solution of the elliptic SPDEs of interest in 2D and 3D and we show convergence of the sampled field covariances. In a MLMC setting, a good coupling is enforced and the telescoping sum is respected.

description: Double print method (print-dry-print-dry) of front contact thick film metallization pastes has been
demonstrated to improve solar cell performance in the R&D stage by reducing series resistance. The resulting
fingerline profile improves the aspect ratio allowing for minimal shading while maintaining or improving fill
factors over current front grid designs. In conjunction with the second layer, the non-contact busbars concept can
be introduced to improve open circuit voltage (Voc) and short circuit current density (Jsc). The second layer
chemistry has been formulated to minimize the silver-silicon contact area as much as possible. With screen
printing as the most economical option for crystalline silicon solar cell manufacturing, double printing will be a
viable option over competing technologies as sheet resistances continue to increase and front grid fingerline widths
continue to decrease.

description: At SRON we are studying the performance of a Goddard Space Flight Center single pixel TES microcalorimeter operated in an AC bias configuration. For x-ray photons at 6 keV the pixel shows an x-ray energy resolution $dE_{FWHM} = 3.7\mathrm{eV}$, which is about a factor 2 worse than the energy resolution observed in an identical DC-biased pixel. In order to better understand the reasons for this discrepancy we characterised the detector as a function of temperature, bias working point and applied perpendicular magnetic field. A strong periodic dependency of the detector noise on the TES AC bias voltage is measured. We discuss the results in the framework of the recently observed weak-link behaviour of a TES microcalorimeter

Asymmetry Helps: Eigenvalue and Eigenvector Analyses of Asymmetrically Perturbed Low-Rank Matrices

description: This paper is concerned with the interplay between statistical asymmetry and spectral methods. Suppose we are interested in estimating a rank-1 and symmetric matrix $\mathbf{M}^{\star}\in \mathbb{R}^{n\times n}$, yet only a randomly perturbed version $\mathbf{M}$ is observed. The noise matrix $\mathbf{M}-\mathbf{M}^{\star}$ is composed of zero-mean independent (but not necessarily homoscedastic) entries and is, therefore, not symmetric in general. This might arise, for example, when we have two independent samples for each entry of $\mathbf{M}^{\star}$ and arrange them into an {\em asymmetric} data matrix $\mathbf{M}$. The aim is to estimate the leading eigenvalue and eigenvector of $\mathbf{M}^{\star}$. We demonstrate that the leading eigenvalue of the data matrix $\mathbf{M}$ can be $O(\sqrt{n})$ times more accurate --- up to some log factor --- than its (unadjusted) leading singular value in eigenvalue estimation. Further, the perturbation of any linear form of the leading eigenvector of $\mathbf{M}$ --- say, entrywise eigenvector perturbation --- is provably well-controlled. This eigen-decomposition approach is fully adaptive to heteroscedasticity of noise without the need of careful bias correction or any prior knowledge about the noise variance. We also provide partial theory for the more general rank-$r$ case. The takeaway message is this: arranging the data samples in an asymmetric manner and performing eigen-decomposition could sometimes be beneficial.

description: A rigorous general definition of quantum probability is given, which is valid for elementary events and for composite events, for operationally testable measurements as well as for inconclusive measurements, and also for non-commuting observables in addition to commutative observables. Our proposed definition of quantum probability makes it possible to describe quantum measurements and quantum decision making on the same common mathematical footing. Conditions are formulated for the case when quantum decision theory reduces to its classical counterpart and for the situation where the use of quantum decision theory is necessary.

Managing global economic crimes as human rights violations in a worldwide perspective : a study of the money laundering process in the international market

description: Second semester University: Université de Montpellier.
description: The thesis provides an overview of the challenges brought about by money laundering in the present globalised world. The policies led to date at the international level for fighting economic crimes present shortcomings in national and international criminal law. Indeed, they tend to make abstraction of the fact that money laundering implies undoublty, either in its performance, or as a consequence, human rights violations. Therefore, the main purpose of this study is to propose a ground-breaking approach with a human rights lens to the fight of both money laundering and its predicate offenses. This thesis examines money laundering impacts over an economic, legal and social dimension The drawbacks of the “Double Track” system of policies implemented to date worldwide are analysed, namely: the AML/CFT criminal/punitive approach, and the AML/CFT preventive/regulatory approach. The conclusions suggest to reshape the present framework. The findings of this thesis point at the necessity to draft and implement a new instrument that would specify the criminalisation of money laundering, establish a direct link between this crime and the perpetration of human rights violations, securing a right to be free from money laundering, and finally establish in parallel an international tribunal for money laundering.

description: We develop the theory of matroids over one-dimensional algebraic groups, with special emphasis on positive characteristic. In particular, we compute the Lindström valuations and Frobenius flocks of such matroids. Building on work by Evans and Hrushovski, we show that the class of algebraic matroids, paired with their Lindström valuations, is not closed under duality of valuated matroids.

description: Deliverable 2.5 “Framework for aligning science education with society: the search for new languages and narratives to enhance imagination and the capacity to talk about contemporary challenges”, presents the results of the reflections, scoping actions, and dialogues fostered and executed by Work Package 2 (WP2). It builds upon the workshops, consultations and desk research looking out for new languages that contribute to stimulating futures thinking in science education. This process is represented in the Framework for Unbound Languages, which represents a roadmap and guide for creating new languages. The new languages suggested by WP2 want to convey actions to be deployed in different spaces, times, disciplines and contexts. Therefore, we named these languages: Languages for adaptation Languages for foraging futures Languages for uncharted territories Languages for interdependencies Together with the framework, a structure based on a card is proposed to showcase different activities to be tested by the Open Schooling Networks. In the last section, a set of recommendations for policymakers is presented that can help foster a zeitgeist familiar with experimentation and freedom to try transdisciplinary ways in science education. Because this document is about new languages, it includes pictures and illustrations that complement the messages communicated by the texts. This document is the fifth deliverable of Work Package 2, “Exploring new languages, narratives and arts in science education - Analysis of Blindspot 2”, led by formicablu.

description: Sputtered indium tin oxide (ITO) has been studied as a TCO for solar cell application. The deposition was
performed with an industrial designed sputtering unit, and corning glass was used as substrate. The effect of annealing on the
electrical and optical properties of ITO films was studied. The films were sputtered in three different ambient; Ar, a mixture
of Ar and O2 and a mixture of Ar and H2. The annealing was performed in air at 300 °C for 15 min. The highest
transmittance (88%) and lowest resistivity of the as-deposited films was achieved when the ITO was sputtered with a 3.3%
oxygen flow (of total flow) added to the working gas (Ar). After annealing, the highest transmittance (91.3%) and lowest
resistivity (2.3 x 10-4 Ω cm) was achieved when the ITO was sputtered without addition of oxygen or hydrogen gas to the
working gas. SIMS measurements were performed on both as-deposited and annealed samples in order to disclose the
elemental composition.

description: We study the approximation of expectations $\operatorname{E}(f(X))$ for solutions $X$ of stochastic differential equations and functionals $f$ on the path space by means of Monte Carlo algorithms that only use random bits instead of random numbers. We construct an adaptive random bit multilevel algorithm, which is based on the Euler scheme, the Lévy-Ciesielski representation of the Brownian motion, and asymptotically optimal random bit approximations of the standard normal distribution. We numerically compare this algorithm with the adaptive classical multilevel Euler algorithm for a geometric Brownian motion, an Ornstein-Uhlenbeck process, and a Cox-Ingersoll-Ross process.

description: Recently, a separation technique to modulated photocurrent signals in FTPS method from monolithic
tandem solar cells was investigated [1]. In this paper similar method to separation I-V curves in monolithic tandem is
investigated. Tandem device is illuminated by small amount of selectively absorbed light modulated by constant
frequency. For tandem two different light excitations are used, ideally at same time and modulated by different
frequencies. Then the appropriate AC components are measured as well as the DC component for a range of applied
voltages. Mathematical formulae describing the problem in their differential form are used to analyze the problem
and finally formulae for deriving 1st derivatives of I-V curves are obtained. After integration and absolute scaling the
I-V curves of separate sub-cells are obtained. The method has been tested on improvised four-terminal device, where
separate I-V curves were measured also directly. First tests were however not done according to all requirements and
comparison with direct measurement showed some misfits.
