description: Bifacial solar cells are known to increase module power and performance. Due to their active rear
side additional gains are possible from internal reflections. Existing models to analyze cell-to-module (CTM) gains
need to be extended. We analyze reflection within modules with bifacial cells and establish a system and a
nomenclature for gains resulting from internal reflection. Transmission through the cell, subsequent reflection on
module cover layers and a second absorption of light in the solar cell leads to additional gains in the range of 0.5 –
0.8% for bifacial cells in modules with reflecting rear cover materials (i.e. white backsheets) under STC conditions.
We present models to calculate gains and perform measurements on bifacial modules with different backsheets and
covers. Cover coupling gains for bifacial cells are higher compared to monofacial cells (20%rel in modules with
white backsheets).

description: Off-grid photovoltaic systems are less constrained by national regulations than their grid-connected counterparts. Off-grid systems do not depend on feed-in tariff and the analysis of their cost-efficiency is more stable along time.
This work calculates the economic parameters for two different technologies of photovoltaic systems and compares the levelized cost of electricity (LCOE), with the price of the electricity, including the cost for the connection of the system related to the distance to the grid. The results show that the sustained decline in photovoltaic module´s price contributes to subsequent decline in LCOE, whereas the increase in the price of grid electricity and materials related to the connection makes off-grid systems more cost-effective for remote areas.
Finally, to determine if the photovoltaic system could be an economic alternative for investments in remote regions, a comparison between the cost of grid extension and the LCOE of a high capacity photovoltaic system was undertaken.

description: We prove that a haploid associative algebra in a $C^*$-tensor category $\mathcal{C}$ is equivalent to a Q-system (a special $C^*$-Frobenius algebra) in $\mathcal{C}$ if and only if it is rigid. This allows us to prove the unitarity of all the 70 strongly rational holomorphic vertex operator algebras with central charge $c=24$ and non-zero weight-one subspace, corresponding to entries 1-70 of the so called Schellekens list. Furthermore, using the recent generalized deep hole construction of these vertex operator algebras, we prove that they are also strongly local in the sense of Carpi, Kawahigashi, Longo and Weiner and consequently we obtain some new holomorphic conformal nets associated to the entries of the list. Finally, we completely classify the simple CFT type vertex operator superalgebra extensions of the unitary $N=1$ and $N=2$ super-Virasoro vertex operator superalgebras with central charge $c<\frac{3}{2}$ and $c<3$ respectively, relying on the known classification results for the corresponding superconformal nets.

description: Ballistic electron transport is a key requirement for existence of a topological phase transition in proximitized InSb nanowires. However, measurements of quantized conductance as direct evidence of ballistic transport have so far been obscured due to the increased chance of backscattering in one dimensional nanowires. We show that by improving the nanowire-metal interface as well as the dielectric environment we can consistently achieve conductance quantization at zero magnetic field. Additionally, studying the sub-band evolution in a rotating magnetic field reveals an orbital degeneracy between the second and third sub-bands for perpendicular fields above 1T.

description: Tesla chose Australia to be one of the first Powerwall Battery delivery countries in the world, because of its tariff structure, high solar radiation values, and high electricity costs. The Powerwall Battery solution was promoted as a low-cost attractive investment, therefore the purpose of this paper is to analyse four scenarios in five Australian states (ACT, SA, VIC, NSW, and QLD) to determine which scenario and respective state presents the highest investment attractiveness. Scenarios 1 and 2 consider an off-grid 5kW PV system with one Powerwall Battery and two Powerwall Batteries respectively. Scenario 3 considers a Powerwall Battery without a PV system connection, which is charged by the household grid and discharged back into the same grid. Scenario 4 studies an on-grid 3kW PV system without a Powerwall Battery practicing a 70% self-consumption regime. The results show that scenario 4 is the most attractive investment option with SA, VIC, and QLD making 3 times the investment within a 25-year investment period and in NSW the investment is doubled. Scenario 1 is currently viable in VIC and only viable after a 10% discount on the Powerwall Battery in QLD.

description: An agent-based model (ABM) is developed in Netlogo as a tool for evaluating temporal diffusion of PV-based communal grids in a rural developing community. ABMs model individual entities within a complex system and the rules that govern the interactions of the entities within the system, to capture the overall effect of such interactions. Results show that given various choices, small PV mircogeneration systems would emerge as the prefered source of electrification for many households. Also, with increasing power demands, many household would prefer communal grids to the national utility grid. Furthermore, introduction of favourable government policies in the form of subsidies and mircocredit facilities, coupled with increasing social acceptance, would lead to increased PV installations and correspondingly to increased communal grid connections. Specifically, introduction of a subsidy of $0.15/kWh would result in an increase of 249% in communal grid connections. Increasing the sensing radius from 1 km to 2 km would result in an increase of 118% in communal grid connections.

description: We investigate the properties of the background gauge field configurations that act as disorder for the Anderson localization mechanism in the Dirac spectrum of QCD at high temperatures. We compute the eigenmodes of the Möbius domain-wall fermion operator on configurations generated for the $SU(3)$ gauge theory with two flavors of fermions, in the temperature range $[0.9,1.9]T_c$. We identify the source of localization of the eigenmodes with gauge configurations that are self-dual and support negative fluctuations of the Polyakov loop $P_L$, in the high temperature sea of $P_L\sim 1$. The dependence of these observations on the boundary conditions of the valence operator is studied. We also investigate the spatial overlap of the left-handed and right-handed projected eigenmodes in correlation with the localization and the corresponding eigenvalue. We discuss an interpretation of the results in terms of monopole-instanton structures.

title: Late-Victorian Celebrity Culture
title: The Interaction of Celebrity, Media and Consumers
titleType: Subtitle
Creators: name: Hughes, Lewis
Publisher: name: Lancaster University
Year: 2020

description: This thesis argues for an amendment to the traditional scholarly visualisation of how celebrity culture functions. In making this argument it looks at the context of late-Victorian Britain, a space and time that I argue harboured the first mass celebrity culture. Instead of the cleanly divided triptych of celebrity, media, and consumers (as proposed most recently by Sharon Marcus), a more integrative model is proposed that seeks to reflect how the three central agents interact and merge seamlessly into one another. This merging of roles, I argue, is a result of the more indiscriminatory, ambiguous, and ‘liquid’ nature of celebrity fame that - unlike the more rigid fame of heroism - does not need to conform as much to pre-set cultural types. In making this argument the thesis looks at four late-Victorian celebrity activities (autobiography, biography, interviews, autograph collecting) that serve as both the central primary sources as well as chapter focuses. In each activity-based chapter the thesis investigates the complex interplay of the three fundamental agents of celebrity, particularly the ways in which they both conflicted and coalesced seamlessly into one another. By doing this, the thesis aims to help inter-disciplinary scholars of celebrity sharpen their theoretical conceptualisation of the phenomenon as well as demonstrate the necessity of accounting for celebrity culture in any thorough discussion of late-Victorian popular culture.

description: Reserve provision from standalone solar photovoltaic (PV) power plants has to date not been adopted in practice but has been conceptualised by a number of authors for variable renewable energy (RE) power plants like solar PV and wind. The authors have assessed the economic viability of this application in a developing country with low-levels of solar PV penetration thusfar (South Africa). The majority of power generation in South Africa is coal-fired, making up over 70% of the installed capacity. However, South Africa has abundant solar resources and has seen a dramatic decline in solar PV tariffs over the past few years. The value of reserve provision to the system from solar PV was determined by simulating the South African power system on an hourly basis in a least-cost unit commitment and dispatch model capable of co-optimising energy and reserves simultaneously. Preliminary results showed that purely reserve provision in the short term by new solar PV in South Africa is not yet economically viable as it requires a solar PV LCOE below 285 ZAR/MWh which is not likely to materialise in the short term.. However, results showed that a combination of reserve provision and energy generation by new solar PV capacity could be economically viable in the short term at solar PV LCOE below 430 ZAR/MWh. This research work is ongoing and will be expanded to include aspects of solar PV forecasting, investigations into the provision of other reserve types by solar PV simultaneously, reserve provision by other Renewable Energy (RE) technologies as well as further research into possible reserve costing and incentivisation.

description: We investigate the plasma and magnetic environment of active region NOAA 11261 on 2 August 2011 around a GOES M1.4 flare/CME (SOL2011-08-02T06:19). We compare coronal emission at (extreme) ultraviolet and X-ray wavelengths, using SDO AIA and RHESSI images, in order to identify the relative timing and locations of reconnection-related sources. We trace flare ribbon signatures at ultraviolet wavelengths, in order to pin down the intersection of previously reconnected flaring loops at the lower solar atmosphere. These locations are used to calculate field lines from 3D nonlinear force-free magnetic field models, established on the basis of SDO HMI photospheric vector magnetic field maps. With this procedure, we analyze the quasi-static time evolution of the coronal model magnetic field previously involved in magnetic reconnection. This allows us, for the first time, to estimate the elevation speed of the current sheet's lower tip during an on-disk observed flare, as a few kilometers per second. Comparison to post-flare loops observed later above the limb in STEREO EUVI images supports this velocity estimate. Furthermore, we provide evidence for an implosion of parts of the flaring coronal model magnetic field, and identify the corresponding coronal sub-volumes associated to the loss of magnetic energy. Finally, we spatially relate the build up of magnetic energy in the 3D models to highly sheared fields, established due to dynamic relative motions of polarity patches within the active region.

description: The fluctuation on the oil prices in the international markets in 2008 coupled with the development of the PV industry led to the gradual integration of PV in the energy mix in many countries in MENA region. Stakeholders in the energy sector started developing the regulations necessary for the development of solar projects in their region. The renewable energy framework in Jordan will be presented with the learning lessons and the development that happened after implementing it for few years.
This paper will present the development of PV Policies and regulations in Jordan since 2008 and the status of installation of PV projects on utility scale and consumer levels. PV on grid and off grid is used at more than 20 applications and some of the most recent installations will be presented. The public-private partnership between the regulators, banking sector, contractors, engineers and suppliers was successful in developing a sustainable model for the continuous integration of more PV projects on grid.
Consumers are now able to meet 100% of the annual electricity needs using on grid PV projects both on site and off sites. The historical cost of generation of electricity in Jordan will be presented with the current electricity prices for different consumer sectors. The attractive payback period for different consumer sectors will be presented with learning lessons and recommendations based on the current prices of PV development.
The driving factors for the growth of the PV sector will be presented. This includes the prices of energy, the demand for more energy, and the energy intensity for a developing economy. The expected development of the electrical distribution and transmission networks development to accommodate the needs of consumers to integrate PV projects will also be presented.
With the continuous decline in the PV Levelized cost of energy, it is expected that more PV will be integrated into the electricity network. This will develop the energy services sector, contractors sector, and the industrial sector that will provide the necessary material that can be locally manufacturer.
Key findings about the development of the PV sector will show that it will contribute to the sustainable development of the energy sector and provide affordable clean energy, with reduced losses in transportation, distribution and transition. The local efforts will be part of the future energy routes and will contribute to the clean energy development in MENA.

description: Students of Kwame Nkrumah University of Science and Technology (KNUST) in Kumasi, Ghana, and of Paderborn
University are working on one renewable energy-related project each year. Those projects are aimed at improving on
innovations or technical developments (renewable energy supply and/or energy efficiency) from young engineers and/or
start-ups in Ghana. The shall enable the young entrepreneurs getting their products developed to maturity, and then
introduced in the West African market. Within the projects, the technical expertise and knowledge will be improved
through common extensive work at all participating universities - together with the inventor and the participating
companies. Besides the technical development, market studies will be conducted, a business plan and a concept for
market introduction will be developed.
The yearly sub-projects are treated similarly to industry-funded technological development projects as they take place at
German universities.
Each project is structured in three phases:
 during summer: preparatory train-the-trainer workshops for the participating staff at KNUST, including the
selection of projects and project coordination
 cooperative student seminars via video conferences
 semesterly meetings at KNUST, review of the projects, presentation to the project partners (inventor / initiator)

description: The phenomenology of magnetic damping is of critical importance for devices that seek to exploit the electronic spin degree of freedom since damping strongly affects the energy required and speed at which a device can operate. However, theory has struggled to quantitatively predict the damping, even in common ferromagnetic materials. This presents a challenge for a broad range of applications in spintronics and spin-orbitronics that depend on materials and structures with ultra-low damping. Such systems enable many experimental investigations that further our theoretical understanding of numerous magnetic phenomena such as damping and spin-transport mediated by chirality and the Rashba effect. Despite this requirement, it is believed that achieving ultra-low damping in metallic ferromagnets is limited due to the scattering of magnons by the conduction electrons. However, we report on a binary alloy of Co and Fe that overcomes this obstacle and exhibits a damping parameter approaching 0.0001, which is comparable to values reported only for ferrimagnetic insulators. We explain this phenomenon by a unique feature of the bandstructure in this system: The density of states exhibits a sharp minimum at the Fermi level at the same alloy concentration at which the minimum in the magnetic damping is found. This discovery provides both a significant fundamental understanding of damping mechanisms as well as a test of theoretical predictions.

description: The electrical consumption of Peru has increased an average of 5.1% annually from 2002 to 2011 while the electrical power demand has shifted from 2700MW to 4800MW as a consequence of the increment in its GDP
In order to overcome this increment in the electricity demand and fostered by the fact that the generation of electricity by means of PV systems is becoming competitive with those traditional energy generation sources, in the recent years, Peru has shifted from being one of the leaders in the installation of Stand-Alone PV systems to become a potential one for large grid-connected PV plants. Nevertheless, in the pathway from small isolated PV “watts” to the last “MW-size” plants installed recently, there is a tremendous gap and technical challenge for the Peruvians, because these large PV systems are being installed by foreign companies using non-local technicians.
Therefore, the present work intends to propose the establishment of the technical background and conditions to encourage the development of the minimum requirements to promote a massive introduction of medium-size (100kW-1MW) distributed photovoltaic systems in Peru throughout the next years. In this direction, this proposal has been made under the technical and training support from the professional team part of the project “Emerging with the Sun” under the formal cooperation framework between the University of Jaen (Spain) and the Universidad Nacional de Ingenieria (Peru).

description: After the oil crisis in the 1970’s, more attention was placed on renewable energy sources, so in the
early 1980’s the first large-scale (>100 kW) PV power plants, based on research and development projects in the
USA and Europe, were commissioned. Over the last four decades, numerous scientific papers and other publications
related to large scale PV projects were published, either as part of R&D scientific projects or as part of other
technical/construction activities. The range of scientific/technical publications about large scale photovoltaic power
plants spans from conference proceedings to magazine papers and also includes some other entries of broader
interest, like books, GIS databases and wall maps for instance. The results of the literature survey, which includes
more than 800 entries among all scientific papers in English and in German, related not only to large-scale
photovoltaic power plants but also to other grid-connected PV projects/power plants, are presented in this paper.

description: Magnetic skyrmions are topologically-protected spin textures that manifest in certain non-centrosymmetric ferromagnets under the right conditions of temperature and field. In thin film skyrmion hosts, demagnetization effects combined with geometric confinement can result in two distinct types of spin textures: those with their axis of symmetry in the plane of the film (IP) and those with their axis pointing out-of-plane (OOP). Here we present Lorentz transmission electron microscopy evidence in conjunction with numerical modeling showing a flop transition between IP and OOP skyrmions in Co$_8$Zn$_8$Mn$_4$ at room temperature. We show that this skyrmion flop transition is controllable via the angle of the external field relative to the film normal and we illustrate how this transition depends on thickness. Finally, we propose a skyrmion-writing device that utilizes the details of this transition.

description: While in the developed countries the transition from AC to DC systems is a topic related to the introduction of
electric vehicles and residential energy storage, in the low-electrified countries this choice is becoming more and
more logical and cost-effective for the energy development.
Starting from small solar lighting systems, we have already met the target of powering small DC appliances such as
TVs, fans, radios and computers with solar energy. Recently the order of magnitude has changed significantly: a few
years ago the market of solar lanterns was about 1 Wp, this number grew to 10 Wp with Solar Home systems and
now it is nearly 100 Wp with kits provided with additional appliances, in continuous current.
Public programs such as Lighting Global or Global Leap are playing an important role for standardization and
technical verification of the products. However, today in most of the countries where these applications could bring
greater environmental, social and economic benefits, there are many practical barriers, presented in this study, that
impede the process of distribution of the products.
In this study, based on our direct experience in more than 40 markets in the last three years, we are going to present
the most common problems that hinder various stakeholders: end users, manufacturers, importers and distributors.
In this field we analyze the role of the NGOs that can be extremely significant or counterproductive, depending on
the approach that is being adopted. Simple donation mechanisms are likely to destroy the development of small local
businesses that would need to be supported financially instead.
Finally, the study will present proposals to make the development of these markets healthier, while maintaining some
understandable commercial tools, such as custom duties, which many countries, especially in Africa, cannot do
without.

description: Digital identifier systems are considered as one of the main areas of application in the identifiable Web approach in digital object theory. Based on the nature of these identifiers, which are based on the implementation of the resolution mechanism and also their differences from other identifiers, the syntax structure of these identifiers has particular importance. The syntax is a set of rules used to combine characters to form an identifier string. This study aims to evaluate the performance of the syntax structure of different digital identifier systems through an illustrative evaluation method and two sequential steps. In the first step, through a Delphi method, a framework was designed to evaluate the structure of systems’ syntax. The framework includes 11 performance indicators: Uniqueness, machine readability, stability, interoperability, simplicity, scalability, verifiability, granularity, character insensitivity, human readability, and syntax resolution. In the second step, 6 well-known global digital identifier systems were mapped in the framework and compared through an illustrative evaluation and TOPSIS methods. According to the findings, DOI (Digital object Identifier) and UCI (Universal Content Identifier) have a robust performance in their syntax structure and Handle, ARK (Archival Resource Key), URN (Uniform Resource Name) and PURL (Persistent Uniform Resource Locator) systems have mediocre performance in this component. Furthermore, the solutions of the robust performance systems in verification, including using the resolution mechanism, the TCP/ IP protocol, and the identifiers with check digits in the suffix, as well as the advantages of qualifiers, in particular, in the more precise identification of the Identified object are discussed. These results can be used by researchers of this field and administrators and users of these systems.

description: We study polynomial identities of algebras with adjoined external unit. For a wide class of algebras we prove that adjoining external unit element leads to increasing of PI-exponent precisely to 1. We also show that any real number from the interval [2,3] can be realized as PI-exponent of some unital algebra.

description: This paper describes the future structure of Japanese electric power generation systems which can reduce life cycle CO2 emissions by more than 90% based on 2010 and also provide economic electricity in 2050. It is important to clarify additional cost to establish a stable grid system with high ratio of variable renewable energy. Firstly, we calculate costs of present and future renewable energy systems using our quantitative methodology. To assess future renewable energy sources such as photovoltaics (PV), wind energy, geothermal, battery and so on, we designed manufacturing processes considering future technology progresses. For example, PV system cost will reach to 60 yen/W in 2030 according to this method. Secondly, we evaluate the cost of electric power systems using our multi-regional power generation model that takes into account the system stability. As a result of the cost minimized power generation model, it is possible to reduce CO2 emissions to 50% based on 2010 without additional cost in 2030. To reduce CO2 emissions by 90% in 2050, electricity cost will tremendously increase. In order to solve this problem, we should develop an economical and also low carbon PV system. Future economical and low carbon power systems are described using calculation results on new PV, battery, hydrogen, etc. which are key issues to be developed towards low cost and low carbon.

description: Tick-Borne diseases can be transmitted via non-systemic (NS) transmission. This occurs when tick gets the infection by co-feeding with infected ticks on the same host resulting in a direct pathogen transmission between the vectors, without infecting the host. This transmission is peculiar, as it does not require any systemic infection of the host. The NS transmission is the main efficient transmission for the persistence of the Tick-Borne Encephalitis virus in nature. By describing the heterogeneous ticks aggregation on hosts through a \hyphenation{dynamical} bipartite graphs representation, we are able to mathematically define the NS transmission and to depict the epidemiological conditions for the pathogen persistence. Despite the fact that the underlying network is largely fragmented, analytical and computational results show that the larger is the variability of the aggregation, and the easier is for the pathogen to persist in the population.

description: Polyhydroxyalkanoates (PHAs) are biodegradable plastic-like materials with versatile properties. Plant oils are excellent carbon sources for a cost-effective PHA production, due to their high carbon content, large availability, and comparatively low prices. Additionally, efficient process development and control is required for competitive PHA production, which can be facilitated by on-line or in-line monitoring devices. To this end, we have evaluated photon density wave (PDW) spectroscopy as a new process analytical technology for Ralstonia eutropha (Cupriavidus necator) H16 plant oil cultivations producing polyhydroxybutyrate (PHB) as an intracellular polymer. PDW spectroscopy was used for in-line recording of the reduced scattering coefficient µs’ and the absorption coefficient µa at 638 nm. A correlation of µs’ with the cell dry weight (CDW) and µa with the residual cell dry weight (RCDW) was observed during growth, PHB accumulation, and PHB degradation phases in batch and pulse feed cultivations. The correlation was used to predict CDW, RCDW, and PHB formation in a high-cell-density fed-batch cultivation with a productivity of 1.65 gPHB·L−1·h−1 and a final biomass of 106 g·L−1 containing 73 wt% PHB. The new method applied in this study allows in-line monitoring of CDW, RCDW, and PHA formation.

description: Socket parity has redefined the business case for rooftop photovoltaics, but it has yet to cause a perceivable increase in global photovoltaic sales. As subsidies for renewables falter across both established and emerging markets, the future of the photovoltaics sector grows increasingly reliant on sustainable niches independent of government support. Small rooftop photovoltaic systems may offer one such opportunity as building occupants in socket-paired markets now stand to save enough money on their utility bills to offset system costs under current market conditions. Such partial electricity autarky raises questions on how to mutualise grid fees and capacity costs fairly. Here, we present markets in which this need not be a challenge. In climates where electricity production peaks close to hours of high insolation, entire communities can benefit on a system level from installing rooftop photovoltaics and diminishing the amount of grid infrastructure needed to meet their peak load. Building on observations across an Australian electrical distribution network, we illustrate the opportunities for decentralised photovoltaics in solar synchronous electricity markets more broadly.

description: Objective: The rapid accumulation of crude-oil based plastics in the environment is posing a fundamental threat to the future of mankind. The biodegradable and bio-based polyhydroxyalkanoates (PHAs) can replace conventional plastics, however, their current production costs are not competitive and therefore prohibiting PHAs from fulfilling their potential. Results: Different low-quality animal by-products, which were separated by thermal hydrolysis into a fat-, fat/protein-emulsion- and mineral-fat-mixture- (material with high ash content) phase, were successfully screened as carbon sources for the production of PHA. Thereby, Ralstonia eutropha Re2058/pCB113 accumulated the short- and medium-chain-length copolymer poly(hydroxybutyrate- co -hydroxyhexanoate) [P(HB- co -HHx)]. Up to 90 wt% PHA per cell dry weight with HHx-contents of 12–26 mol% were produced in shake flask cultivations. Conclusion: In future, the PHA production cost could be lowered by using the described animal by-product streams as feedstock.

description: Process engineering of biotechnological productions can benefit greatly from comprehensive analysis of microbial physiology and metabolism. Ralstonia eutropha (syn. Cupriavidus necator) is one of the best studied organisms for the synthesis of biodegradable polyhydroxyalkanoate (PHA). A comprehensive metabolomic study during bioreactor cultivations with the wild-type (H16) and an engineered (Re2058/pCB113) R. eutropha strain for short- and or medium-chain-length PHA synthesis has been carried out. PHA production from plant oil was triggered through nitrogen limitation. Sample quenching allowed to conserve the metabolic states of the cells for subsequent untargeted metabolomic analysis, which consisted of GC–MS and LC–MS analysis. Multivariate data analysis resulted in identification of significant changes in concentrations of oxidative stress-related metabolites and a subsequent accumulation of antioxidative compounds. Moreover, metabolites involved in the de novo synthesis of GDP-l-fucose as well as the fucose salvage pathway were identified. The related formation of fucose-containing exopolysaccharides potentially supports the emulsion-based growth of R. eutropha on plant oils.
