description: Idea of the card game Build your own high-dimensional quantum computer. By applying quantum logic operations to high-dimensional quantum bits – so-called qudits -, you can change their values. Try to reach the highest possible value on your qudit, while keeping the other player’s qudit as low as possible. The game offers three modes of playing - easy, 2D, and 3D - with increasing complexity. The evaluation software calculates the state whenever a played card is entered. It then calculates the final state after each round, in which a certain number of measurements will project possible complex superposition states into a final value. The player with the highest qudit values in three rounds wins the game. In addition, there are a few riddle cards (incl. solutions on the back side) that can be solved by single players. See instructions for a detailed description of the game. Please also have a look at the manuscript detailing the ideas behind the game and how quantum effects such as superposition, interference, and entanglement can be observed when playing. The preprint version of the manuscript can be found here: https://arxiv.org/abs/2107.12007 The upload contains: instructions pdf-file to print the cards pdf-file to print the riddle cards program to evaluate the outcome of the game (python code as well as executable application) NOTE: The general idea is strongly based on the great card game Q|Cards> by Oskari Kerppo, Jorden Senior, Sabrina Maniscallo, Guillermo Garcia-Perez, Samuli Jääskeläinen, Sylvia Smatanova, Krista Erkkilä, Elie Abraham, which is a very similar game using only qubits.

description: Novel phosphorus paste for emitter and back surface field (BSF) is introduced. The phosphorus paste is
finely printed on textured p- and n-type multicrystalline silicon wafers. The phosphorus contents were adjusted to
form excellent emitter quality and insure at the same time the reproducibility of emitter formation. The emitter sheet
resistance decreased with increasing the diffusion temperature, duration and phosphorus contents in the paste. In
addition, the fabricated solar cells having screen-printed phosphorus emitter had more potential. This phosphorus
paste can provide the industry with the cheapest possible way to form the back contact solar cell without the need of
complicated masking process.
title: Work on the move: mobilities of creativity and design ideation
Creators: name: Firth, Richard
Publisher: name: Edinburgh Napier University
Year: 2021

description: This thesis focuses on the development of original design ‘ideation’ processes (the formation of ideas or concepts) set within the context of both commercial museum and exhibition design contracts and product design pedagogic research. Taken together the published works that accompany this submission explore the impacts on productivity and creative problem solving when working away from a physical fixed studio or office-based environment. They also examine the significance of 'shared place' when working directly with a client in situ, as well as place-based influences upon the business of the client. This thesis identifies location as part of the design process and examines the effects of time restriction and working ‘in transit’ upon creativity and productivity. The integration and impact of new and emerging mobile technologies on creative workflow processes is also explored in the context of my own practice between 2007 and 2019. I define my workflow process as the journey from idea generation and development through to production, manufacture and installation.

My contribution to new knowledge is the creation of an ideation methodology made up of assembled methods which are defined by drawing, mobility and moving image. I have established methods of using drawings as props to facilitate design ideation. I have developed visual schematics tools to communicate teaching and learning feedback loops. I have built on the concept of learning spaces as the static stages of learning and developed a process of using the time moving between locations as a fluid learning space to allow for observation, reflection, discussion and ideation. I employ moving image as a tool to capture feedback and curate the design processes. I consider my methods original by virtue of their cross-disciplinary approach and use of different methodologies.
title: Change of the leader in an organisation and its impact on employee engagement
Creators: name: Gilkes, Glenda
Publisher: name: Edinburgh Napier University
Year: 2021

description: Current research highlights change of the leader as the new normal as organisations respond to austerity measures forced by changes in the global economy, shifting markets, mergers and acquisitions and rapid technological advancement. The Caribbean is not immune from these dynamics as many companies are foreign owned and led and as such, experience similar predicaments. Yet, there is a lack of understanding on how these changes affect employee engagement and more so, how employees should respond to them. Furthermore, there is a dearth of literature in academia that can fully respond to this new phenomenon of leadership change that is occurring at a rapid pace. Thus, the purpose of this study is to augment the lack of literature on the relationship between change of the leader and employee engagement. It highlights a new focus or gap on the employees’ responses to leadership change. The study pays specific attention to leadership change at the Chief Executive Officer (CEO) level.

An initial pilot study using a qualitative questionnaire provided direction for the development of the mixed method approach used in this ii research. Two instruments were developed from the responses in the pilot that guided the implementation of a scale and a focus group aimed at understanding the experiences of leadership change and its impact on employee engagement. A sample of 51 participants were selected from two financial institutions in Barbados. Employee engagement was used as the indicator of a successful leadership change and the conceptual framework demonstrates the co-dependency of human resource driven factors to mitigate the impact of organisational change on employees.

The findings revealed that unmanaged changes can wreak havoc in the organisation and employee engagement can be drastically affected by this occurrence. The type of effect however, is largely dependent on how this change is implemented and managed. Engagement may also be affected by the complexity, potential disruption and fallout experienced by employees. Though in some instances change of the leader may be as a result of attrition and can therefore be planned and well managed, all types of leadership change whether planned or unplanned must be adequately managed. The findings have shown that while change is inevitable, it can be managed by a well thought out communication strategy, bolstered by a trusting environment where there is a culture of transparency and truthfulness. Further, the Human Resources professional as a change agent can be used to help manage this process. Along with other recommendations, this study provides a toolkit to guide organisations through a successful change of the leader at the CEO level.
title: Optimisation of monitoring using camera-traps and field evidence when identifying Eurasian otter Lutra lutra resting or breeding sites
Creators: name: Findlay, Melanie
Publisher: name: Edinburgh Napier University
Year: 2021

description: The Eurasian otter Lutra lutra and its resting places are protected by EU and UK legislation. Consultant ecologists must identify resting sites so they can be protected during developments. Currently, consultants usually use field-signs, but radio-telemetry studies indicate this may be unreliable. Camera-traps could be used to identify resting sites within the consultancy industry. This research aims to improve field-sign and camera-trap survey methods to identify otter resting sites. Firstly, camera-trap methodology is considered. Arrays of camera-traps were used with continuous CCTV as a control so the effect of variables on detection success of mammal passes could be modelled. A six-year camera-trap study of an active breeding and resting site was analysed to optimise set-up. Distance from the camera-trap had a negative effect on trigger probability but a positive effect on registration probability (i.e. the probability that an image or video is captured given a trigger). Slower animals had greater trigger and registration probabilities while otters had reduced detection after immersion in water. A reduction of video clip duration, and exclusion of daytime monitoring would have reduced the amount of time watching video footage with minimal data loss. These findings guided a camera-trap study of 26 potential resting sites where field evidence was recorded at 21-day intervals. The camera-trap data was also used to identify rests and any relationships between resting and field evidence were investigated. A rest could only be observed on CT footage and was defined as an otter being within a structure for ≥ 15min. According to this criteria, six of the 26 sites were resting sites, with 95% of rests occurring in winter and spring. Latrines were exclusive to resting sites, and presence of bedding material was strongly related to resting sites. Data simulations calculated that a period of 35 days of camera-trapping in winter, repeated in spring would have a 95% probability of detecting a rest. These findings contribute to the evidence-base for guidelines for ecologists to identify resting sites as required by law. The patterns of otter activity, behaviour and field-signs provide a comparison for further studies. The research focusses on otter, but the approaches and principles could be applied more widely.

Large PV Power Plants and Distributed PV: System Aspects and Grid Connection

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 3902-3907
description: This study examines the reactive power ancillary services of solar inverters which are connected to low
voltage (LV) distribution networks by giving attention to the grid voltage support service and grid losses. Two typical
reference LV distribution network models as suburban and farm are introduced from the literature in order to
evaluate contribution of two static droop strategies cos(P) and Q(U) on the grid voltage. Photovoltaic (PV) hosting
capacities of the suburban and farm networks are estimated and the most predominant limitations of connecting more
solar inverters are emphasized for each network type. Regarding the overloading of MV/LV distribution
transformers, overloading of lines and the grid overvoltage limitations, new local grid voltage support methods
(cos(P,U) and Q(U,P)) are also proposed. Resulting maximum allowable penetration levels with different reactive
power methods are presented by load flow simulation.
title: Wild birds as a reservoir of antimicrobial resistance (AMR) in the environment
Creators: name: Djuwanto, Bimo Andrianus
Publisher: name: Edinburgh Napier University
Year: 2021

description: Antimicrobial resistance (AMR) is one of the greatest public health threats and has been conceptualised as a slowly emerging disaster. Studies have suggested that wild birds contribute as a reservoir and dispersal route of AMR, and proximity to anthropogenic activity has been associated with higher prevalence of AMR. This study was conducted to determine the prevalence and diversity of extended-spectrum β-lactam (ESBL) resistant coliforms in wild bird populations in Scotland across a gradient of anthropogenic activity. Two bird taxa with functional differences were selected: gulls and geese and sampled across areas of different anthropogenic activity: urban and rural. A total of 226 bird faecal samples (47 gull faeces from a waste water treatment works (WWTW), 50 gull faeces from a rural site, 77 goose faeces from city lochs and 52 goose faeces from a rural site) were screened using a selective media. To determine diversity of isolates, up to 10 resistant and sensitive colonies from each sample were selected and tested using REP-PCR. One isolate from each REP type was selected for further characterisation including E. coli strain diversity, phylo-groups, sequence type (ST), susceptibility testing and resistance genes. This study found a significantly higher prevalence of ESBL-producer E. coli (57% urban vs 2% rural) and ESBL-producer non-E. coli coliforms (32% urban vs 4% rural) in gulls at the urban site compared to the rural site. The difference in the prevalence of ESBL-producer non-E. coli coliforms in geese in the urban (5%) and rural (17%) sites was not statistically significant. Of 33 E. coli REP types identified, 88% were distinctly carried by birds. Six phylo-groups and one cryptic clade were detected, and the phylo-group B1 was the most prevalent. Multi-drug resistant (resistance ≥ 3 antibiotic classes) E. coli were only found in gulls at the WWTW (urban site). The most common ESBL-producer gene in this study was blaCTX-M group 1. This study suggests that gulls feeding on a WWTW site have a major role as a reservoir of AMR, whereas geese in urban lochs and migratory geese have a minor role.

description: We introduce several families of $\mathcal{N}=(2,2)$ UV boundary conditions in 3d $\mathcal N=4$ gauge theories and study their IR images in sigma-models to the Higgs and Coulomb branches. In the presence of Omega deformations, a UV boundary condition defines a pair of modules for quantized algebras of chiral Higgs- and Coulomb-branch operators, respectively, whose structure we derive. In the case of abelian theories, we use the formalism of hyperplane arrangements to make our constructions very explicit, and construct a half-BPS interface that implements the action of 3d mirror symmetry on gauge theories and boundary conditions. Finally, by studying two-dimensional compactifications of 3d $\mathcal{N}=4$ gauge theories and their boundary conditions, we propose a physical origin for symplectic duality - an equivalence of categories of modules associated to families of Higgs and Coulomb branches that has recently appeared in the mathematics literature, and generalizes classic results on Koszul duality in geometric representation theory. We make several predictions about the structure of symplectic duality, and identify Koszul duality as a special case of wall crossing.

description: Given a sequence of $n$ independent random variables with common continuous distribution, we propose a simple adaptive online policy that selects a monotone increasing subsequence. We show that the expected number of monotone increasing selections made by such a policy is within $O(\log n)$ of optimal. Our construction provides a direct and natural way for proving the $O(\log n)$-optimality gap. An earlier proof of the same result made crucial use of a key inequality of Bruss and Delbaen (2001) and of de-Poissonization.

Silicon Solar Cell Improvements

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 1309-1312
description: This work is devoted to the study of boron doping diffusion process for n-type silicon solar cells
applications. Deposition temperature and O2 flow rate are important parameters in the diffusion process. In this paper
we investigate their influence by using an industrial scale diffusion furnace (LYDOPTM Boron, Semco-Engineering).
Boron profiles are obtained by SIMS (Secondary Ion Mass Spectrometry) analysis and simulated by a numerical
model based on oxidation-enhanced diffusion (OED). We observed that the boron diffusion profiles could be
correctly simulated by a single fitting parameter. This parameter, noted FBoron is connected to the chemical reaction
kinetics developed at the interface between the boron silicon glass (BSG) and the silicon substrate. We also have
shown that the experimental boron profile is not depending on the O2 flow rate in contrast to the proposed model
based on the OED (Oxidation Enhanced Oxidation) mechanism. Indeed, it seems that the oxidation reaction appears
only on the BRL (Boron-Rich Layer) layer.
title: The effects of menstrual cycle phases on running repeated sprint ability
Creators: name: Di Nicola, Samuele
Publisher: name: Edinburgh Napier University
Year: 2021

description: Female participation in regular sport activities has increased in recent years, yet their representation in the sports and exercise science literature remains low. Therefore, an understanding of the effects different phases of the menstrual cycle (MC) have on exercise responses is important due to the practical and theoretical implications. The aim of this study was to compare performance, physiological and perceptual differences when performing a running repeated sprint ability (RSA) during the early-follicular (EF), and mid-luteal (ML) sub-phases of the MC. Six healthy, physically active female participants (age: 25.67 ± 2.49 years; height: 1.66 ± 0.08 m; body mass: 69.8 ± 19.3 kg; V̇O2peak: 46.00 ± 6.76 ml·kg¹·min⁻¹) took part in this study. After the initial health screening, the participants completed two familiarisation and four intervention sessions (twice during each MC sub-phase). The RSA protocol consisted of five ‘all-out’ sprints of six seconds on a non-motorised treadmill with 24 seconds of active recovery (walking) between the sprints. Results indicated no significant differences between MC sub-phases in mean (p = 0.998, d = 0.00) and peak power output (p = 0.14, d = 0.16), distance (p = 0.59, d = 0.07), pre-exercise (p = 0.78, d = 0.41) and post-exercise lactate (p = 0.58, d = 0.24), oxygen uptake (p = 0.10, d = 0.30), respiratory exchange ratio (p = 0.47, d = 0.13), ventilation (p = 0.42, d = 0.12), heart rate (p = 0.49, d = 0.17). However, significant differences were found in peak acceleration (EF: 4.65 ± 0.84 m·s⁻², ML: 5.05 ± 1.14 m·s⁻²) (p = 0.02, d = 0.40) and rating of perceived exertion (RPE) (EF: 13.42 ± 2.15, ML: 12.60 ± 2.26) (p < 0.001, d = 0.37). In conclusion, MC phases do not appear to influence most of the chosen RSA performance indicators. However, due to the low sample size and statistical power, further studies are required to better investigate the effects of the MC on RSA.

description: We discuss the limitations of the covariant derivative expansion prescription advocated to compute the one-loop Standard Model (SM) effective lagrangian when the heavy fields couple linearly to the SM. In particular, one-loop contributions resulting from the exchange of both heavy and light fields must be explicitly taken into account through matching because the proposed functional approach alone does not account for them. We review a simple case with a heavy scalar singlet of charge $-1$ to illustrate the argument. As two other examples where this matching is needed and this functional method gives a vanishing result, up to renormalization of the heavy sector parameters, we re-evaluate the one-loop corrections to the T--parameter due to a heavy scalar triplet with vanishing hypercharge coupling to the Brout-Englert-Higgs boson and to a heavy vector-like quark singlet of charged $2/3$ mixing with the top quark, respectively. In all cases we make use of a new code for matching fundamental and effective theories in models with arbitrary heavy field additions.

description: This contribution shows a way to a significant increase of safety in PV plants. By combination of two
long-term proven technologies – but restricted in USA respectively Europe - a system can be created avoiding and
controlling arcs in an optimum way.
Circuits for arc-detection, which are widely-used in the USA, are introduced to be used for the DC-side of PV plants
in 2011 [1]. These devices are detecting serial arcs and disconnecting the load.
In US PV installations currently parallel arcs can only be detected in case of a ground fault. Then they are detected by
the GFDI (Ground Fault Detection and Interruption). In case of an evenly spread degradation of the isolation the
GFDI is lost upon. In contrast most of the European generators are ungrounded. In the majority of cases they run with
an isolation monitoring device, which is able to detect symmetric isolation faults, too. The degradation of the
isolation is noticed long time before getting dangerous. There is enough time for repair before a parallel arc might
occur.
The work combines both of these technologies and expands it by installation aspects. It pointed out, how the safety of
PV plants can be raised considerably by small adjustments.

description: We study the evolution of a system of M particles in contact with a large reservoir of N>>M particles. The reservoir is initially in equilibrium at temperature T=1/β. The evolution of the system and reservoir is described via a suitable Kac-style collision process. We show that for large N, this evolution can be effectively described by replacing the reservoir with a Maxwellian thermostat at temperature T. This description provides an approximation that is uniform in time both in a suitable L^2 norm and in the Gabetta-Toscani-Wennberg (GTW) distance.

title: Exosomes as mediators of cell-to-cell communication in prostate cancer
Creators: name: Bruce, Isla
Publisher: name: Edinburgh Napier University
Year: 2021

description: Prostate cancer (PCa) is dependent on androgens for growth. Androgen deprivation therapy (ADT) curtails PCa progression, however this powerful selective pressure leads to aggressive, castrate resistant PCa. One castrate resistant prostate cancer subtype, neuroendocrine (NE) PCa, is characterised by increased abundance of NE cells. Transdifferentiation into androgen independent NE-like cells is thought to allow PCa epithelial cells to escape potent ADT, causing resistance. NE-like cells are thought to promote growth of surrounding tumour cells through paracrine communication. Exosomes are small extracellular vesicles released from all cells. They can be endocytosed by neighbouring cells and modify cellular function through their cargo (proteins and RNAs). Exosomes have been proposed to promote PCa NE-transdifferentiation (NEtD); by an unknown mechanism. This project aimed to isolate and characterise exosomes from NE-like cells and investigate their potential role in driving neuroendocrine PCa.

LNCaP cells were cultured in media containing charcoal-stripped FCS to deplete androgens as an in vitro model of AD (androgen deprivation) to promote NEtD. NEtD was confirmed by analysing LNCaP morphology, immunoblotting and qRTPCR, investigating markers of the androgen receptor and NEtD. Exosomes are prevalent in FCS and may mask exosomes released from NE-like LNCaP cells, therefore exosomes were depleted from FCS/charcoal-stripped FCS by differential centrifugation. Exosome depletion did not affect LNCaP NEtD morphology or expression of androgen receptor and NEtD markers. However, AD increased expression of markers of the exosomal machinery (ALIX, CD9, HSP70 TSG101, RAB27A, VAMP7) as seen by qRT-PCR, suggesting AD may enhance exosome production. Exosomes were isolated from LNCaP and NE-like LNCaP culture medium to analyse exosome size, number and content by dynamic light scattering and immunoblotting. AD increased exosomal number and CD9 expression, suggesting NEtD is associated with increased exosome release. Exosome release from LNCaP cells was reduced by GW4869 and enhanced by Monensin. GW4869 regressed NEtD in AD LNCaP cells while Monensin induced NEtD in control LNCaP cells and enhanced AD LNCaP cells.

description: Solar cell metallization is a major efficiency-limiting and cost-determining step in solar cell processing.
Screen printed metallization is the most widely used contact formation technique for commercial Si solar cell.
However, the screen-printed contacts are 125-150 um wide, which gives rise to high shading losses. And fill factors
are low (~0.75) because of high contact resistance, low metal conductivity, and junction shunting. This work
demonstrates that the high efficiency (~19.1%) mono-crystalline Si solar cell (Area=15.6 x 15.6 cm2) with a
selective emitter structure used in the conventional diffusion process (POCl3) and the screen printed contact is
presented in this paper. In particular, we focus on the improvement of fill factor (FF) by the front metal Ag portion
and aspect ratio optimization.

description: We consider a one-dimensional spin-orbit-coupled nanowire quantum dot, driven by external electric and magnetic fields, and theoretically formulate an electric mechanism to interfere its electron orbits. Owing to the existence of spin-orbit coupling and a pulsed electric field, different spin-orbit states are shown to interfere with each other, generating intriguing interference-resonant patterns. We also reveal that an in-plane magnetic field does not affect the strength interval of any neighboring resonant peaks, but contributes a weak shift of each peak, which is sensitive to the direction of the magnetic field. We find that this proposed external-field-controlled scheme should be regarded as a new type of quantum-dot-based interferometry. Finally, this interferometry has an important application in precisely measuring relative experimental parameters, such as the Rashba and Dresselhaus spin-orbit-coupling strengths, as well as the Lande-g factor.
title: Evaluation of engagement with hyperlocal e-participation systems by citizens and representatives
Creators: name: Cruickshank, Peter
Publisher: name: Edinburgh Napier University
Year: 2021

description: This work is concerned with the information practices associated with hyperlocal representation. The findings derive from an evaluation of a portfolio of ten previously published papers covering the period 2010-2020.

The main contributions are: (a) The development of the concept of hyperlocal representation as a domain with its own challenges; (b) The characterisation of hyperlocal representatives as stakeholders in the participation process; and (c) Expansion of the existence and nature of lurkers as passive participants in the participation process, and the responses seen in the information sharing practices of the hyperlocal representatives, including use of information sharing by proxy. These contributions are significant because they are the first to consider community councillors as information actors in their own right, and their response to lurking behaviours in their community. This is in contrast with previous research at this level of government, which has focussed on the activities of citizens, and local government administration staff.

The portfolio demonstrates the application of frameworks derived from information science to the field of e-participation. It identifies the impact of the project- and information systems-based nature of much e-participation research, and proposes an information-centric perspective from information science to support a new analysis, through application of theoretical approaches derived from everyday life information practice, information literacy, activity systems and communities of learning. An additional contribution is the creation of a new model of the transition from lurking to participation based on social-cognitive theory. A further contribution of the thesis is to methodologies in information science, in particular through the design of questionnaires and supporting interviews as data collection instruments in this context.

This thesis adds to understanding of information sharing in a quasi-work context where there are limited expectations of interaction. It could support future research into the information practice of representatives in (a) the choice of channels for communication with citizens, (b) the information communities involved in the representation role and (c) the impact of the policy cycle on information practices.
title: Fatigue and the mind-body relation: a Lacanian exploration
Creators: name: Diserholt, Amanda
Publisher: name: Edinburgh Napier University
Year: 2020

description: This thesis explores the symptomatology of fatigue based on interviews conducted with seven people who are diagnosed with Chronic Fatigue Syndrome/Myalgic Encephalomyelitis. The thesis starts by examining how a biomedical view of fatigue — the dominant perspective in contemporary Western society — is underpinned by aporetic divisions, such as mind/body and individual/society. In pursuit of a more rigorous approach to fatigue, which explores rather than disavows division, the interview transcripts are analysed through the lens of Lacanian theory. The analysis commences with an exploration of the onset of the participants’ conditions, drawing on Lacan’s notion of alienation. This brings to light a common experience of a confrontation with the capitalistic demand to ‘keep going’, as well as experience of facing contradictory demands. Lacan’s notion of separation allows us to appreciate the emergence of fatigue as one way of unconsciously refusing these demands. This refusal consists of two intertwined but contradictory forces: the drive (which articulates to pain/tension and signals presence) and a defensive desire (which articulates to fatigue itself and signals disappearance). This allows us to understand a complex of phenomena related to the experience of fatigue, ranging from anorexia to mourning. The thesis then turns to the relation between the onset events and the participants’ responses to them. Here Lacan’s theory of the clinical structures is utilised in order to illuminate details around the function and structure of fatigue. This returns us to the conventional separation of the mind and body, showing how current medical and psychological approaches are unable to adequately account for the current findings. The thesis concludes by elucidating how the main points are situated within a larger sociocultural context, arguing for a view of the mind-body relation which moves beyond the aporia while refusing any reduction to either pole.

We find ray trajectories that maximize the intensity inside the cavity to determine the far-field emission characteristics and to complement the concept of the unstable manifold applicable to chaotic microlasers. As these maximum intensity trajectories need not to be periodic, we suggest that they provide a more general explanation for emission patterns of microlasers than short periodic orbits. Further, the geometrical optics description is extended by the inclusion of intensity amplification along the optical path to achieve a better description of active, lasing cavities. Far-field emission patterns of equilateral triangle cavities obtained in this way agree well with our full electromagnetic wave simulations and with previously reported experimental results.

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 3930-3934
description: SolarGIS is a new generation web service (http://solargis.info) aimed to increase efficiency and reduce uncertainty in
planning and performance assessment of PV systems. SolarGIS is based on more than 10 years of R&D, international
collaboration, and experience with previous projects, such as PVGIS. The system consists of high-resolution database
of solar radiation and air temperature (which are operationally calculated for Europe, Africa, Asia and Brazil) and
some other auxiliary parameters. Solar radiation is calculated from Meteosat Prime and IODC satellites data covering
a period from 1994 (2000) to the present. Derived solar parameters are calculated for any fixed-mounted or suntracking
PV. Air temperature is derived from atmospheric models from ECMWF and NCEP. SolarGIS integrates
previously published and validated PV performance models to simulate module surface reflectivity, non-linearities in
the conversion efficiency due to irradiance/temperature outdoor conditions for c-Si, CdTe, and CIS/CIGS modules
and shading. Four applications are implemented in the system: (i) iMaps - high-resolution global interactive maps and
data, (ii) climData - interactive and automated access to solar radiation and air temperature; (iii) pvPlanner - PV
performance simulator with a new concept of simulation algorithms and data formats and (iv) pvSpot – a tool for
performance evaluation and monitoring of PV systems. The key innovation of SolarGIS involve: (i) high-resolution
and detailed solar radiation database, extensively validated and documented, (ii) Implementation of a new aerosol
database from ECMWF into solar radiation model, (iii) Increased accuracy of PV simulation, (iv) Possibilities of
near-real time data delivery, (v) Detailed interactive maps, precise geo-positioning and availability of other support
data.

description: Weyl fermions can be created in materials with both time reversal and inversion symmetry by applying a magnetic field, as evidenced by recent measurements of anomalous negative magnetoresistance. Here, we do a thorough analysis of the Weyl points in these materials: by enforcing crystal symmetries, we classify the location and monopole charges of Weyl points created by fields aligned with high-symmetry axes. The analysis applies generally to materials with band inversion in the $T_d$, $D_{4h}$ and $D_{6h}$ point groups. For the $T_d$ point group, we find that Weyl nodes persist for all directions of the magnetic field. Further, we compute the anomalous magnetoresistance of field-created Weyl fermions in the semiclassical regime. We find that the magnetoresistance can scale non-quadratically with magnetic field, in contrast to materials with intrinsic Weyl nodes. Our results are relevant to future experiments in the semi-classical regime.

description: We introduce an intrinsic Lyα emission line profile reconstruction method for high-$z$ quasars (QSOs). This approach utilises a covariance matrix of emission line properties obtained from a large, moderate-$z$ ($2 \leq z \leq 2.5$), high signal to noise (S/N > 15) sample of BOSS QSOs. For each QSO, we complete a Monte Carlo Markov Chain fitting of the continuum and emission line properties and perform a visual quality assessment to construct a large database of robustly fit spectra. With this dataset, we construct a covariance matrix to describe the correlations between the high ionisation emission lines Lyα, C IV, Si IV + O IV] and C III], and find it to be well approximated by an $N$-dimensional Gaussian distribution. This covariance matrix characterises the correlations between the line width, peak height and velocity offset from systemic while also allowing for the existence of broad and narrow line components for Lyα and C IV. We illustrate how this covariance matrix allows us to statistically characterise the intrinsic Lyα line solely from the observed spectrum redward of 1275Å. This procedure can be used to reconstruct the intrinsic Lyα line emission profile in cases where Lyα may otherwise be obscured. Applying this reconstruction method to our sample of QSOs, we recovered the Lyα line flux to within 15 per cent of the measured flux at 1205Å (1220Å) ~85 (90) per cent of the time.

description: For CuIn(S,Se)2-based solar cells made from electroplated CuInSe2 precursors, a rapid thermal
processing in a sulphur-containing atmosphere is necessary to ensure grain growth and sulphurization. It has been
shown recently [Izquierdo-Roca et al. J. Appl. Phys.103 (2008)] that annealing at higher temperature gives better
structural and morphological properties as well as higher efficiencies. However annealing cells made on soda-lime
glass at temperatures above the glass transition temperature Tg can cause thermo-mechanical issues. Cracking of the
molybdenum, telephone-cord delamination and a high residual curvature of the multilayer have been observed after
annealing. These phenomena do not prevent elaboration of small-sized cells but are not acceptable for up-scaling. A
better knowledge of the stress build-up in the consecutive layers is therefore required.
Stresses in the molybdenum and CuIn(S,Se)2 layers have been determined before and after annealing using both
Stoney’s formula and the sin²() method. A mechanical behaviour is proposed which explains the observed
phenomena and the high stress values measured in the molybdenum layer after annealing. It is also shown that
mechanical damage is mainly due to the coefficient of thermal expansion mismatch between molybdenum and glass
and that the CuIn(S,Se)2 layer has very little influence on the molybdenum state of stress.

description: Following a special conference focused on object-based learning in higher education at University College London (UCL), this paper provides the overview for a series of subsequent papers which explore the value of object-based learning, including the pedagogical framework for museum learning in the university classroom and practice led examples from a range of disciplines. Object-based learning in higher education draws on many of the learning strategies already known to inform students, including active learning and experiential learning; this collection of papers draws together examples of object-based learning pioneered at UCL and seeks to encourage enhanced use of university collections in new, pedagogically powerful, modes.

description: In this paper the zero modes of fluctuation of cylindrically symmetric self-dual vortices are analyzed and described in full detail. These BPS topological defects arise at the critical point between Type II and Type I superconductors, or, equivalently, when the masses of the Higgs particle and the vector boson in the Abelian Higgs model are equal. In addition, novel bound states of Higss and vector bosons trapped by the self-dual vortices at their core are found and investigated.

description: Within the framework of a Norwegian national project, KMB-Defect Engineering, a report describing the
currently available techniques for characterization of silicon solar cell has been written. The report is divided
into four chapters. The first chapter defines and describes the physical parameters. The second chapter is a
summary of the cost and availability of the different characterization techniques. The third chapter describes all
currently available techniques for silicon solar cell. The fourth chapter reviews the most common sample
preparation methods.
In this work, we present a summary of this report and describe briefly most of the characterization tools
currently available for silicon solar cell. The techniques are divided according to the characterization targets
which are i) electrical parameters, ii) dimension and topographic parameters, iii) crystallographic parameters
and structural defect, iv) mechanical parameters, v) optical parameters and vi) impurity concentration and
defect parameters.
We believe that this review is relevant for both the research- and industry communities, and can be a useful
tool for further development of measurement techniques for the photovoltaic industry.

Silicon Solar Cell Improvements

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 1293-1296
description: In contrast to the conventional beamline ion implantation techniques, Intevac ENERGi implanter
utilizes the continuous flux ion implantation technique which enhances the implant-induced damage accumulation.
In this paper, defect-free recrystallization of amorphous layer which was first created by the continuous flux ion
implantation was demonstrated. Electrical activation and defect annealing data indicate the possibility of reducing
the thermal budget required for the traditional beam ion implantation techniques in post-implant damage anneal and
dopant activation. Using its high dose rate and by taking advantage of the benefits of solid phase epitaxial re-growth
(SPER) phenomenon, it was demonstrated the cost of silicon-based solar cell manufacturing processes can be
significantly reduced with the high wafer throughput and possibly reduce the need for the subsequent furnace
annealing step in dopant activation and implant damage anneal.
