description: Russia represents a vast sales market for solar systems. Therefore, the evaluation of potential conditions and solar plants implementation efficiency are essential. The vast territory of Russia is not provided with required density of meteorological data sampling stations. While designing solar plants the problem of solar energy income definition with the required level of reliability, as well as that of tracking systems use expediency, is crucially important. It is particularly essential for integrated solar plants and remote sites in thinly-populated rural areas that compose the major part of the territory of the country. This work is dedicated to the establishing the calculation formulas for solar radiation income definition and to the analysis of operation efficiency of solar plants having different orientations for any area in Russian territory.

description: Defect characterizes the depth of factorization of terms in differential (cyclotomic) expansions of knot polynomials, i.e. of the non-perturbative Wilson averages in the Chern-Simons theory. We prove the conjecture that the defect can be alternatively described as the degree in $q^{\pm 2}$ of the fundamental Alexander polynomial, which formally corresponds to the case of no colors. We also pose a question if these Alexander polynomials can be arbitrary integer polynomials of a given degree. A first attempt to answer the latter question is a preliminary analysis of antiparallel descendants of the 2-strand torus knots, which provide a nice set of examples for all values of the defect. The answer turns out to be positive in the case of defect zero knots, what can be observed already in the case of twist knots. This proved conjecture also allows us to provide a complete set of $C$-polynomials for the symmetrically colored Alexander polynomials for defect zero. In this case, we achieve a complete separation of representation and knot variables.

description: Die Exklusion bestimmter Feminismen und die Ignoranz gegenüber der Komplexität von Diskriminierungserfahrungen sorgt für Kritik am sog. Weißen Feminismus. Schon von den feministischen Errungenschaften des 19. und 20. Jahrhunderts profitierten nicht alle Frauen gleichermaßen. Auch heute werden nicht alle Frauen gleichermaßen gehört, während bestimmte Emanzipationskonzepte verabsolutiert und romantisiert werden. Die Hierarchie der Feminismen ist oft nicht zufällig, sondern folgt einer rassistischen Exklusionslogik. Dabei böten Vielfältigkeit und Inklusion die Chance, humanistische und feministische Grundwerte ernst zu nehmen.

description: Due to the knowledge of the rotation period and the presence of a rather strong surface magnetic field, the sharp-lined young Herbig Ae star HD 101412 with a rotation period of 42 d has become one of the most well-studied targets among the Herbig Ae stars. High-resolution HARPS polarimetric spectra of HD 101412 were recently obtained on seven different epochs. Our study of the spectral variability over the part of the rotation cycle covered by HARPS observations reveals that the line profiles of the elements Mg, Si, Ca, Ti, Cr, Mn, Fe, and Sr are clearly variable while He exhibits variability that is opposite to the behaviour of the other elements studied. Since classical Ap stars usually show a relationship between the magnetic field geometry and the distribution of element spots, we used in our magnetic field measurements different line samples belonging to the three elements with the most numerous spectral lines, Ti, Cr, and Fe. Over the time interval covered by the available spectra, the longitudinal magnetic field changes sign from negative to positive polarity. The distribution of field values obtained using Ti, Cr, and Fe lines is, however, completely different compared to the magnetic field values determined in previous low-resolution FORS 2 measurements, where hydrogen Balmer lines are the main contributors to the magnetic field measurements, indicating the presence of concentration of the studied iron-peak elements in the region of the magnetic equator. Further, we discuss the potential role of contamination by the surrounding warm circumstellar matter in the appearance of Zeeman features obtained using Ti lines.

description: We investigate the mechanical structure of a spin-1 particle. Introducing three different frameworks, i.e., the three-dimensional (3D) Breit frame, the two-dimensional (2D) Breit frame, and the 2D infinite momentum frame (equivalently the two-dimensional Drell-Yan frame), we scrutinize the 2D and 3D energy-momentum tensor (EMT) distributions in these frames. We first derive the EMT distributions in the 2D Breit frame by performing the Abel transformation. The mass distribution in the 2D Breit frame contains an additional monopole contribution induced geometrically. The pressure distribution in the 2D Breit frame also gets an induced monopole structure. When the Lorentz boost is carried out, the mass distribution in the 2D infinite-momentum frame acquires the induced dipole term. Similarly, we also have the induced dipole contributions to the pressure and shear-force densities. We visualize the 2D mass distributions when the spin-1 particle is polarized along the $x$- and $z$-axes. We observe that the 2D mass distribution in the infinite momentum frame exhibit clearly the induced dipole structure when the spin-1 particle is polarized along the $x$-axis. We also discuss the strong force fields inside a polarized spin-1 particle.

description: The benefits of hybridising two solar technologies are not clear at first sight. Combining the low cost electricity generation by photovoltaics (PV) with the cheap thermal energy storage option available to concentrating solar thermal power (CSP) plants is what makes this package interesting. In this work we simulate hybrid power plants over the course of one year using historical hourly weather data on the input side and synthetic load data on a national level on the output side. In addition to examining pure PV-CSP plants we also consider adding wind power and direct battery storage to the mix. The economics of such combinations are determined and compared. The results show that PV-CSP hybrids are a viable option to provide an output profile following national electricity demand. We also show that when allowing a wide range of power generation and storage technologies, at any given location many different combinations lead to levelised electricity costs not too far above the minimal possible costs for any renewable power source.

description: The cost of generating electricity with rooftop photovoltaics is dropping below the utility rates offered to residential consumers in a growing number of markets. This has not yet led to a perceptible increase in sales or change in business models. Even governments continue to support residential photovoltaic systems with financial incentives to compensate owners for the electricity that their photovoltaic system produces when they cannot consume it themselves. This study shows that by tailoring the capacity of rooftop photovoltaic installations to the load profile of a residential building, households in Germany, Italy and Spain could now save money on their electricity expenses using rooftop photovoltaic systems without any market distortions, storage systems, changes in consumer habits or any need to feed electricity back into the grid. The size of these financially optimal rooftop photovoltaic systems averaged 1.1 kWp per household in Germany using 2013 prices and is increasing as the price for photovoltaic systems comes down. These results highlight the existence of an underexploited, multigigawatt market for unsubsidised photovoltaics in Europe and possibly other parts of the world.

description: In the foreseeable future, sustainable electrical energy systems should be capable to handle up to 100% of renewable energy share in the electricity grid. Due to the recent price drops, PV will play a major role in the global renewable energy portfolio. The technical implications of this development (also referred to as "energy transition" in Germany) in all areas of electricity supply (generation, transmission, distribution, operation management) are manifold and consequently lead to a new system design. For the effective integration of PV the major challenges are volatile generation given by sun’s position and actual weather conditions, as well as load level. On one hand, the article addresses the generation side by adapting PV power plants to load requirements (e.g., via azimuth and tilt angle modification to achieve peak power output during periods of high demand, via thermal conditioning of PV modules, via smart site selection or via a combination of complementary energy sources) and on the other hand the article discusses several possibilities of load management (e.g. load shifting, inducements, load adaptation, appropriate market design).

PV Globalisation, Policies and Administrative Issues

description: 29th European Photovoltaic Solar Energy Conference and Exhibition; 3989-3993
description: The RES Directive 2009/28/CE paves the way for a solid cooperation between European Member states but also
reinforces the international collaboration with third countries such as the Middle East North Africa (MENA) countries.
Articles 9 and 10 of the RES Directive regulate the implementation of joint projects between one or more European
Member States and one or more third countries in order to enhance the cross border exchange of renewable energy.
Besides their high solar potential, only few MWp of PV have been installed until today in MENA countries. Even though
the RES Directive provides the European Member States with clear guidelines on how to implement the cross border
exchange of renewable energy, until now the European Members States have not implemented the flexible mechanisms to
exchange renewable energy among European Member States and third countries.
In this paper the reasons behind this missing exchange of RES between Europe and MENA countries have been
investigated. The work presented in this paper has been based on the results obtained with the PV Parity project, which
was co-financed by the European Commission, under the Intelligent Energy Programme, and started in June 2011 and
ended in November 2013. This paper also provides an overview on the results related to the PV competitiveness in South
Africa.
The results achieved within the PV Parity projects have been discussed with all relevant stakeholders, such as the
European Commission, distributor systems operators, utilities, regulators, energy agencies. This has been done in order to
provide policy makers with objective and transparent information to guarantee a sustainable PV electricity generation in
MENA countries and Africa.

description: Remote/off-grid applications were the first terrestrial markets for PV and dominated from the late 1970s until the late 1990s when grid connected markets were created by economic incentive policies. These large markets have driven PV down the experience curve and brought prices for PV systems down by at least two orders of magnitude since the late 1970s. This paper examines how the vastly improved economics of PV combined with improvements in application and information technology, improved economies in emerging market countries, and innovative business models are creating a new growth of off-grid remote markets for PV.

description: We present an online visual analytics approach to helping users explore and understand hierarchical topic evolution in high-volume text streams. The key idea behind this approach is to identify representative topics in incoming documents and align them with the existing representative topics that they immediately follow (in time). To this end, we learn a set of streaming tree cuts from topic trees based on user-selected focus nodes. A dynamic Bayesian network model has been developed to derive the tree cuts in the incoming topic trees to balance the fitness of each tree cut and the smoothness between adjacent tree cuts. By connecting the corresponding topics at different times, we are able to provide an overview of the evolving hierarchical topics. A sedimentation-based visualization has been designed to enable the interactive analysis of streaming text data from global patterns to local details. We evaluated our method on real-world datasets and the results are generally favorable.

description: The amount and spatial pattern of heat extracted from cores of terrestrial planets is ultimately controlled by the thermal structure of the lower rocky mantle. Using the most common model to tackle this problem, a rapidly rotating and differentially cooled spherical shell containing an incompressible and viscous liquid is numerically investigated. To gain the physical basics, we consider a simple, equatorial symmetric perturbation of the CMB heat flux shaped as a spherical harmonic $Y_{11}$. The thermodynamic properties of the induced flows mainly depend on the degree of nonlinearity parametrised by a horizontal Rayleigh number $Ra_h=q^\ast Ra$, where $q^\ast$ is the relative CMB heat flux anomaly amplitude and $Ra$ is the Rayleigh number which controls radial buoyancy-driven convection. Depending on $Ra_h$ we characterise three flow regimes through their spatial patterns, heat transport and flow speed scalings: in the linear conductive regime the radial inward flow is found to be phase shifted $90^\circ$ eastwards from the maximal heat flux as predicted by a linear quasi-geostrophic model for rapidly rotating spherical systems. The advective regime is characterised by an increased $Ra_h$ where nonlinearities become significant, but is still subcritical to radial convection. There the upwelling is dispersed and the downwelling is compressed by the thermal advection into a spiralling jet-like structure. As $Ra_h$ becomes large enough for the radial convection to set in, the jet remains identifiable on time-average and significantly alters the global heat budget in the convective regime. Our results suggest, that the boundary forcing not only introduces a net horizontal heat transport but also suppresses the convection locally to such an extent, that the net Nusselt number is reduced by up to 50\%, even though the mean CMB heat flux is conserved.

description: Canary Island is a Spanish archipelago located in front of the Morocco coast. Tenerife is the largest and most populous island of the seven Canary Islands, it is also the most populated island of Spain, with a land area of 2,034.38 square kilometers (785 sq mi) and 898,680 inhabitants (year 2012), 43 % of the total population of the Canary Islands. Tenerife is also the largest and most populous island of Macaronesia. However due to this weather and touristic facilities, over 7 million of tourists visit Tenerife every year. From the point of view of the electricity demand, Tenerife is isolated both from other Canary Island and the mainland and its diary peak demand is around 530MW. The installed technologies in the island are combined cycle, gas turbine, vapor turbine, diesel motors, wind power and photovoltaic power. During the valley hours, in the range of 1 a.m. to 6 a.m., the demand decrease until 300 MW. Due to the operation system, the production technologies cannot be disconnected during the night so the generation systems are not working in the maximum efficiency points. Despite this matter, the production costs during the night are lower than the maximum peak demand. In this work we analyze the generation costs in the island and the generation curve when electrical cars are connected during the valley hours to be recharged and reconnected during the peak hours to supply energy and stabilize the grid.

description: The Magellanic Clouds, two dwarf galaxy companions to the Milky Way, are among the Fermi Large Area Telescope (LAT) brightest gamma-ray sources. Aiming at a comprehensive modeling of the non-thermal electromagnetic and neutrino emission in both Clouds, we self-consistently model the radio and gamma-ray spectral energy distribution from their disks based on recently published Murchison Widefield Array and Fermi/LAT data. All relevant radiative processes involving relativistic and thermal electrons (synchrotron, Compton scattering, and bremsstrahlung) and relativistic protons (neutral-pion decay following interaction with thermal protons) are considered, using exact emission formulae. Our joint spectral analyses indicate that radio emission in the Clouds has both primary and secondary electron synchrotron and thermal bremsstrahlung origin, whereas gamma rays originate mostly from neutral-pion decay with some contributions from relativistic bremsstrahlung and Compton scattering off starlight. The proton spectra in both galaxies are modeled as power laws in energy with similar spectral indices, ~2.4, and energy densities, ~1 eV/cm3. The predicted 0.1-10 GeV neutrino flux is too low for detection by current and upcoming experiments. Our analyses confirm earlier suggestions of a largely hadronic origin of the gamma-ray emission in both Magellanic Clouds.

description: Giant radio sources (GRSs) defined to be > 0.7 Mpc are the largest single objects in the Universe and can be associated with both galaxies (GRGs) and quasars (GRQs). They are important for understanding the evolution of radio galaxies and quasars whose sizes range from pc to Mpc scales and are also valuable probes of their environment. These radio-loud active galactic nuclei (RLAGN) interact with the interstellar medium of the host galaxy on small scales and the large-scale intracluster or intergalactic medium for the GRSs. With several new and sensitive surveys over the last few years, the number of known GRSs has increased many fold which has led a resurgence of interest in the field. This review article summarises our current understanding of these sources based on nearly five decades of research and discusses the importance of the Square Kilometer Array (SKA) in addressing some of the outstanding questions.

description: We present a study of the possible self-consumption of PV electricity by individual households. The study is based on electricity consumption time series data from 144 households in Ulm, Germany. PV power estimates using solar radiation data from satellite are used to calculate the instantaneous PV power self-consumption for each household under a number of scenarios. The results show that with a PV system producing 1/3 of the total annual electricity consumption, the self-consumption may reach 60-90% of the PV electricity while for a PV system producing the same annual energy as the consumption, the self-consumption is reduced to 20-40%. Adding battery storage may significantly increase PV self-consumption. For a PV system producing half the annual consumption, the percentage of self-consumption increases from 40-60% to 70-85%, with a storage size of 3kWh per kWp of PV system.

description: The chirped-pulse interaction in the adiabatic coupling regime induces cyclic permutations of the energy states of a three-level system in the $V$-type configuration, which process is known as the three-level chirped rapid adiabatic passage. Here we show that a spectral hole in a chirped pulse can turn on and off one of the two adiabatic crossing points of this process, reducing the system to an effective two-level system. The given hybrid adiabatic-nonadiabatic transition results in selective excitation of the three-level system, controlled by the laser intensity and spectral position of the hole as well as the sign of the chirp parameter. Experiments are performed with shaped femtosecond laser pulses and the three lowest energy-levels (5S$_{1/2}$, 5P$_{1/2}$, and 5P$_{3/2}$) of atomic rubidium ($^{85}$Rb), of which the result shows good agreement with the theoretically analyzed dynamics. The result indicates that our method, being combined with the ordinary chirped-RAP, implements an adiabatic transitions between the two excited states. Furthermore the laser intensity-dependent control may have applications including selective excitations of atoms or ions arranged in space when being used in conjunction with laser beam profile programming.

description: The most adopted definition of asexuality is simple — does not experience sexual attraction. In reality, however, people who identify as asexual are a very heterogeneous group, and more recognition and representation of this variety is needed. Through the analysis of existing asexual visual representations, this thesis proposes that new opportunities are arising for more nuanced representations that acknowledge the diversity of the asexual experience and help others further understand what asexuality can be. A small-scale qualitative visual study was conducted to extract symbolic visual elements of online asexual communities. Drawing from those elements, two projects and one experiment were undertaken to explore how visual communication tactics can be used to bring forth more nuanced asexual representations. Two projects propose to associate a broadened understanding of asexuality with the diverse asexual experience in visual representations: Andy Warhol is Aro Ace situates asexual possibilities in a broader cultural and historical context through visual storytelling; and #intimAces interprets common physical interactions from an asexual perspective, linking asexual/nonsexual intimacy with symbols of asexuality. An experiment of symbol-making for asexual spectrum identities seeks clarifications of the specific definitions, leading to a discussion around identity segmentation and the role of design to bring more fluidity. This thesis concludes by suggesting an inclusion of more nuances and possibilities of asexuality for future asexual visibility and education.

description: As the generation of squeezed states of light has become a standard technique in laboratories, attention is increasingly directed towards adapting the optical parameters of squeezed beams to the specific requirements of individual applications. It is known that imaging, metrology, and quantum information may benefit from using squeezed light with a tailored transverse spatial mode. However, experiments have so far been limited to generating only a few squeezed spatial modes within a given setup. Here, we present the generation of single-mode squeezing in Laguerre-Gauss and Bessel-Gauss modes, as well as an arbitrary intensity pattern, all from a single setup using a spatial light modulator (SLM). The degree of squeezing obtained is limited mainly by the initial squeezing and diffractive losses introduced by the SLM, while no excess noise from the SLM is detectable at the measured sideband. The experiment illustrates the single-mode concept in quantum optics and demonstrates the viability of current SLMs as flexible tools for the spatial reshaping of squeezed light.

description: In the Discover phase of a design project, students can focus unjustly on current implementations of products and services and current societal norms. Future thinking aims to encourage users to consider the next generation, the products and services they will use in the future and the societal norms that will govern what would become a successful innovation. Signals is a tool that highlights current trends away from the norm, why these trends are significant and why they will become more critical in the future. Signals are currently being used as part of the Scottish Institute for Enterprise, Scottish Innovative Student Award (SISA) programme, where students from across Scotland are invited to attend innovation workshops to develop entrepreneurship skills. Signals are the starting point of these workshops to consider future solutions suitable for tomorrow's society. This paper will discuss the use of Signals with Design students and the benefits observed in the design process.

Some matrix nearness problems suggested by Tikhonov regularization

description: The numerical solution of linear discrete ill-posed problems typically requires regularization, i.e., replacement of the available ill-conditioned problem by a nearby better conditioned one. The most popular regularization methods for problems of small to moderate size are Tikhonov regularization and truncated singular value decomposition (TSVD). By considering matrix nearness problems related to Tikhonov regularization, several novel regularization methods are derived. These methods share properties with both Tikhonov regularization and TSVD, and can give approximate solutions of higher quality than either one of these methods.

Modeling the Daily Variations of the Coronal X-ray Spectral Irradiance with Two Temperatures and Two Emission Measures

description: The Miniature X-ray Solar Spectrometer (MinXSS-1) CubeSat observed solar X-rays between 0.5 and 10 keV. A two-temperature, two-emission measure model is fit to each daily averaged spectrum. These daily average temperatures and emission measures are plotted against the corresponding daily solar 10.7 cm radio flux (F10.7) value and a linear correlation is found between each that we call the Schwab Woods Mason (SWM) model. The linear trends show that one can estimate the solar spectrum between 0.5 keV and 10 keV based on the F10.7 measurement alone. The cooler temperature component of this model represents the quiescent sun contribution to the spectra and is essentially independent of solar activity, meaning the daily average quiescent sun is accurately described by a single temperature (1.70 MK) regardless of solar intensity and only the emission measure corresponding to this temperature needs to be adjusted for higher or lower solar intensity. The warmer temperature component is shown to represent active region contributions to the spectra and varies between 5 MK to 6 MK. GOES XRS-B data between 1-8 Angstroms is used to validate this model and it is found that the ratio between the SWM model irradiance and the GOES XRS-B irradiance is close to unity on average. MinXSS-1 spectra during quiescent solar conditions have very low counts beyond around 3 keV. The SWM model can generate MinXSS-1 or DAXSS spectra at very high spectral resolution and with extended energy ranges to fill in gaps between measurements and extend predictions back to 1947.

description: In her cumulative dissertation, Sophie Hinger examines local responses to and consequences of asylum migration. She starts from the observation that the way asylum migration and refugees are dealt with locally is not only conditioned by (inter-)national policies and their implementation, but by a multitude of actors and factors and their interaction. By interrogating different ‘zones of negotiation’ (reception, accommodation, deportations, integration policy) and drawing on numerous original interviews, observations, and documents, she analyses discourses and practices of inclusion and exclusion of refugees. The medium-sized German city of Osnabrück serves as an entry point for the investigation of these multi-scalar and multi-local zones of negotiation. Sophie Hinger argues that at the heart of local negotiations over asylum lies the contested presence of protection-seekers and the opportunities for participation that result from this presence or are claimed based on it. She advances the notion of a ‘politics of presence’, which denotes those practices that challenge attempts to control migration and existing boundaries of belonging and opportunities for participation. The politics of presence comprise the implicit politics of refugees' coming to and being in the city, explicit demands for opportunities to participate, as well as institutional measures of inclusion (even or especially if these oppose restrictive national migration and asylum policies). Such practices are not necessarily local or urban, but as is argued in the dissertation, it is often in and through cities that conflicts over the presence of asylum seekers are played out and that the politics of presence come to the fore. With the concept of the politics of presence, Sophie Hinger contributes to debates on local migration politics at the intersection of migration, urban, and social movement studies.
