description: Aims. Using a suite of cosmological chemodynamical disc galaxy simulations, we assess how (a) radial metallicity gradients evolve with scaleheight; (b) the vertical metallicity gradients change through the thick disc; and (c) the vertical gradient of the stellar rotation velocity varies through the disc. We compare with the Milky Way to search for analogous trends. Methods. We analyse five simulated spiral galaxies with masses comparable to the Milky Way. The simulations span a range of star formation and energy feedback strengths and prescriptions, particle- and grid-based hydrodynamical implementations, as well as initial conditions/assembly history. Results. Consistently, we find that the steeper, negative, radial metallicity gradients seen in the mid-plane flatten with increasing height away from the plane. In simulations with stronger (and/or more spatially-extended) feedback, the negative radial gradients invert, becoming positive for heights in excess of 1 kpc. Such behaviour is consistent with that inferred from recent observations. Our measurements of the vertical metallicity gradients show no clear correlation with galactocentric radius, and are in good agreement with those observed in the Milky Way's thick disc (locally). Conclusions. Simulations employing stronger/more extended feedback prescriptions possess radial and vertical metallicity and kinematic gradients more in line with recent observations. The inverted, positive, radial metallicity gradients seen in the simulated thick stellar discs originate from a population of younger, more metal-rich, stars formed in-situ, superimposed upon a background population of older migrators from the inner disc; the contrast provided by the former increases radially, due to the inside-out growth of the disc. A similar behaviour may be responsible for the same flattening seen in the radial gradients with scaleheight in the Milky Way.

description: Satellite based models to retrieve solar radiation have been in development over the past three decades.
These models produce global horizontal irradiance (GHI) and direct normal irradiance (DNI) using models that
follow either an empirical or physical approach. Although empirical methods have been used traditionally for
computing surface radiation the advent of faster computing has made operational physical models viable. The Global
Solar Insolation Project (GSIP) is an operational physical model from the National Oceanic and Atmospheric
Admnistration (NOAA) that computes GHI using visible and infrared channel measurements from Geostationary
Operational Environment Satellites (GOES). GSIP uses a two-stage scheme that first retrieves cloud properties, then
uses those properties in a radiative transfer model to calculate surface radiation. The National Renewable Energy
Laboratory (NREL), University of Wisconsin, and NOAA have collaborated to adapt GSIP to create a 4-km GHI and
DNI product every 30 minutes. In this paper we present a short outline of the method, a comprehensive validation
using high-quality ground-based solar data as well as results of ongoing improvements in the modeling.

description: Utilizing recent advances in the formation of thin crystalline silicon layers and also in laser technology,
a monolithic cell structure can be formed simply and practically. By using a laser to melt and dope right through the
thickness of the wafer, juxtaposed regions of opposite polarity can be formed to electrically isolate adjacent devices
while simultaneously facilitating their series interconnection through the formation of a low impedance junction. By
this means, a wafer can be divided up into many smaller series connected cells. Such a structure enables the active
devices to be made without any metal contacts, which are usually required to carry larger electrical currents long
distances, but in so doing, compromise the cells simplicity, durability, cost and performance such as through shading
and recombination at the metal interfaces. Other recent developments well suited to such a structure include high
quality surface passivation and hydrogenation methods that enable device voltages above 700 mV and semiconductor
fingers, which allow low series resistance even without the use of metal.

description: Detailed numerical simulations of intrinsic Josephson junctions of high temperature superconductors under external electromagnetic radiation are performed taking into account a charge imbalance effect. We demonstrate that the charge imbalance is responsible for a slope in the Shapiro step the value of which increases with a nonequilibrium parameter. Coupling between junctions leads to the distribution of the slope's values along the stack. The nonperiodic boundary conditions shift the Shapiro step in IV-characteristics from the canonical position determined by $V_{ss}=\hbar f /(2e)$, where $f$ is a frequency of external radiation. This fact makes ambiguous the interpretation of the experimentally found Shapiro step shift by the charge imbalance effect.

description: Narrow-band red-emitting phosphors are a critical component in phosphor-converted light-emitting diodes for highly efficient illumination-grade lighting. In this work, we report the discovery of a quantitative descriptor for narrow-band Eu2+-activated emission identified through a comparison of the electronic structure of known narrow-band and broad-band phosphors. We find that a narrow emission bandwidth is characterized by a large splitting of more than 0.1 eV between the two highest Eu2+ 4f7 bands. By incorporating this descriptor in a high throughput first principles screening of 2,259 nitride compounds, we identify five promising new nitride hosts for Eu2+-activated red-emitting phosphors that are predicted to exhibit good chemical stability, thermal quenching resistance and quantum efficiency, as well as narrow-band emission. Our findings provide important insights into the emission characteristics of rare-earth activators in phosphor hosts, and a general strategy to the discovery of phosphors with a desired emission peak and bandwidth.

description: We investigate the critical endline of the finite temperature phase transition of QCD around the SU(3)-flavor symmetric point at zero chemical potential. We employ the renormalization-group improved Iwasaki gauge action and non-perturbatively $O(a)$-improved Wilson-clover fermion action. The critical endline is determined by using the intersection point of kurtosis, employing the multi-parameter, multi-ensemble reweighting method to calculate observables off the SU(3)-symmetric point, at the temporal size $N_{\rm T}$=6 and lattice spacing as low as $a \approx 0.19$ fm. We confirm that the slope of the critical endline takes the value of $-2$, and find that the second derivative is positive, at the SU(3)-flavor symmetric point on the Columbia plot parametrized with the strange quark mass $m_s$ and degenerated up-down quark mass $m_{\rm l}$.

description: We searched for quasi-periodicities on year-like timescales in the light curves of 6 blazars in the optical - near infrared bands and we made a comparison with the high energy emission. We obtained optical/NIR light curves from REM photometry plus archival SMARTS data and we accessed the Fermi light curves for the $γ$-ray data. The periodograms often show strong peaks in the optical and gamma-ray bands, which in some cases may be inter-related. The significance of the revealed peaks is then discussed, taking into account that the noise is frequency dependent. Quasi-periodicities on a year-like timescale appear to occur often in blazars. No straightforward model describing these possible periodicities is yet available, but some plausible interpretations for the physical mechanisms causing periodic variabilities of these sources are examined.

description: Within the framework of a flat cosmological model a propagation of an instantaneous burst of isotropic radiation is considered from the moment of its beginning at some initial redshift z0 to the moment of its registration now (at z=0). Thomson scattering by free electrons and scattering in primordial hydrogen lines Ha, Hb, Pa and Pb are considered as the sources of opacity and when calculating an albedo of a single scattering in the lines we take into account deactivation of the upper levels of transitions by background blackbody radiation. Profiles for these lines in a burst spectrum are calculated for different distances from the center of the burst and different values of z0. In the first approximation these profiles do not depend on spectrum and intensity of a burst radiation. It is shown that lines are in absorption at sufficiently large distance but emission components may appear as a distance decreases and it becomes stronger while absorption component weakens with a further distance decrease. For the sum of Ha and Hb lines the depth of absorption can reach 2e-4 while for the sum of Pa and Pb lines the maximum absorption is about 7e-6. So that the relative magnitude of temperature fluctuations lies between 1e-7 and 1e-9. The calculations were fulfiled for bursts with different initial sizes. For the same z0 the profiles of hydrogen lines are practically coinside for burst sizes lower than someone and for greater ones the lines weaken as the burst size grows.

description: Direct marketing and consumption on site of PV electric energy will require short period predictions
based on short period meteorological prognoses. This is different from the calculation of an annual Performance
Ratio (PR) since short periods lack the counterbalancing effects of an extended period.
The presentation addresses two topics: 1) Which elements of a meteorological prognosis day-ahead or week-ahead
are required to estimate a PR value suited for that period / that prognosis? Are changes of the standard calculation
procedures required for this? 2) Given a site- and product- specific short period PR calculation – how can it be used
to analyze short period field data?
We investigate PV systems at several European sites by a stepwise calculation of the relevant PR contributions,
looking for the impact to the precision of short period PR results. The day PR contributions of the losses referring to
shading, reflection, low irradiance and inverter COP show a quite pronounced dependence on day irradiation sum,
which may be used for day-ahead calculations.
The common modeling of module temperature as linear function of ambient temperature and irradiance is insufficient
for short period calculations. An extended model taking into account wind velocity is required. This is shown by
comparison with a detailed module temperature reference calculation. A simple algorithm how to include the wind
velocity – suited for day-ahead calculations – is proposed and tested.
Finally an evaluation procedure for short period field data including soiling is proposed which makes use of the
findings reported.

description: Recently, the first association between an ultra-long gamma-ray burst (GRB) and a supernova is reported, i.e., GRB 111209A/SN 2011kl, which enables us to investigate the physics of central engines or even progenitors for ultra-long GRBs. In this paper, we inspect the broad-band data of GRB 111209A/SN 2011kl. The late-time X-ray lightcurve exhibits a GRB 121027A-like fall-back bump, suggesting a black hole central engine. We thus propose a collapsar model with fall-back accretion for GRB 111209A/SN 2011kl. The required model parameters, such as the total mass and radius of the progenitor star, suggest that the progenitor of GRB 111209A is more likely a Wolf-Rayet star instead of blue supergiant, and the central engine of this ultra-long burst is a black hole. The implications of our results is discussed.

description: We use Rabi spectroscopy to explore the low-energy excitation spectrum of a finite-temperature Bose gas of rubidium atoms across the phase transition to a Bose-Einstein condensate (BEC). To record this spectrum, we coherently drive the atomic population between two spin states. A small relative displacement of the spin-specific trapping potentials enables sideband transitions between different motional states. The intrinsic non-linearity of the motional spectrum, mainly originating from two-body interactions, makes it possible to resolve and address individual excitation lines. Together with sensitive atom-counting, this constitutes a feasible technique to count single excited atoms of a BEC and to determine the temperature of nearly pure condensates. As an example, we show that for a nearly pure BEC of N = 800 atoms the first excited state has a population of less than 5 atoms, corresponding to an upper bound on the temperature of 30 nK.

description: We investigate opinion formation in a kinetic exchange opinion model, where opinions are represented by numbers in the real interval $[-1,1]$ and agents are typified by the individual degree of conviction about the opinion that they support. Opinions evolve through pairwise interactions governed by competitive positive and negative couplings, that promote imitation and dissent, respectively. The model contemplates also another type of nonconformity such that agents can occasionally choose their opinions independently of the interactions with other agents. The steady states of the model as a function of the parameters that describe conviction, dissent and independence are analyzed, with particular emphasis on the emergence of extreme opinions. Then, we characterize the possible ordered and disordered phases and the occurrence or suppression of phase transitions that arise spontaneously due to the disorder introduced by the heterogeneity of the agents and/or their interactions.

description: We present the first crystalline Si-based tandem solar cell device consisting of a monolithically interconnected c-Si wafer bottom and a Si nanocrystal (NC) top solar cell. The major part of this work has been realised within a European consortium in the frame of the FP7 project NASCEnT. Within this project we have been able to (i) develop new nanomaterials with photovoltaic compatible technologies, to (ii) improve the theoretical understanding of transport, recombination and dopant incorporation in these quantum confined absorber materials and to (iii) design devices which enable us to prove quantum confinement. In this publication we show that although solid phase crystallisation at 1100 °C for around 30 min is necessary to generate Si NCs of proper quality the wafer bottom cell as well as the c-SiC(n+) tunnel recombination junction layer can withstand such harsh conditions. Besides simulations to determine the influence of the high thermal budget on dopant profiles in wafer and c-SiC lifetime measurements on parallel processed wafers still show minority carrier lifetimes of 600 μs. The bifacial character of the tandem device enables us to clearly distinguish between bottom and top cell contributions. With a NC layer thickness of initially 3 nm Voc values as high as 978 mV could be achieved at 1 sun illumination from the front-side. Under rear-side illumination the short circuit current Jsc is with 1.0 mA/cm2 4 times higher that under front side illumination due to the better absorption and carrier lifetime of the bottom cell but still limited by the series resistance of the intrinsic NC absorber material. However, at 510 mV the Voc is much lower, indicating the difference in Voc is due to photogenerated voltage in the NC top cell which can only be created by illumination with low-wavelength light, i.e. front illumination. This very first tandem solar cell device including quantum dot absorber layers produced with photovoltaic compatible processes is the next step to successfully overcome the Shockley-Queisser limit for wafer based Si solar cells.

description: aSi-modules show large variations in their response to the incoming irradiance as measures by band
irradiance sensors, making the check and prediction of their performance difficult when only broadband data are
available. One approach to overcome this difficulty is given by the use of detailed models to estimate the irradiance
spectra from the broadband data. Here, it is tested to what degree the detailed modeling could be substituted by a
semi-empirical approach to reflect the modules response based on but the information on direct and diffuse irradiance
and solar geometry. The model performance is measured by its capability to give the correct monthly mean shortcircuit
current together with a reasonable R2 value of the scatter of modeled and measured data. A first test of a
respective model has shown reasonable results.

description: The magnetospheric cusps are important sites of the coupling of a magnetosphere with the solar wind. The combination of both ground- and space-based observations at Earth have enabled considerable progress to be made in understanding the terrestrial cusp and its role in the coupling of the magnetosphere to the solar wind via the polar magnetosphere. Voyager 2 fully explored Neptune's cusp in 1989 but highly inclined orbits of the Cassini spacecraft at Saturn present the most recent opportunity to repeatedly studying the polar magnetosphere of a rapidly rotating planet. In this paper we discuss observations made by Cassini during two passes through Saturn's southern polar magnetosphere. Our main findings are that i) Cassini directly encounters the southern polar cusp with evidence for the entry of magnetosheath plasma into the cusp via magnetopause reconnection, ii) magnetopause reconnection and entry of plasma into the cusp can occur over a range of solar wind conditions, and iii) double cusp morphologies are consistent with the position of the cusp oscillating in phase with Saturn's global magnetospheric periodicities.

Terrestrial Concentrator Systems

description: 28th European Photovoltaic Solar Energy Conference and Exhibition; 94-97
description: Concentrator Photovoltaic (CPV) systems
are a potential candidate to achieve low cost solar energy
[1]. In these systems the efficiency of the solar cell
increases with concentration and the amount of
semiconductor material required is lower. CPV systems
use Fresnel lenses to focus the light into homogenizers,
which provide uniform illumination to the subjacent solar
cell and does other optical corrections. A disadvantage of
these optical elements is that they create three optical
interfaces that reflect the incident light and together
account for about 12% of losses. To achieve higher
efficiency in CPV systems, these losses need to be
addressed. In this paper we report on the EQE
enhancement of a Quantum-Dot Solar Cell (QDSC) placed
below PMMA substrates with antireflection structures
fabricated by Inducted Coupled Plasma etching (ICP).
These structures were also applied on the front and back
sides of the latest generation Fresnel lenses [2].
Transmittance improvement was measured on the textured
Fresnel lenses. Finally, field tests were carried out and
enhancements of Jsc and efficiency were demonstrated.

description: Frans Florschütz (1887‒1965) developed pollen analysis in the Netherlands as a biostratigraphical tool on the interface between geology, palaeobotany, soil science and climate history. He was involved in agricultural practice and the building of large infrastructure. Florschütz established centres of pollen analysis at the universities in Wageningen (1924) and Utrecht (1928), was appointed professor in Leiden (1948) and after retirement founded a chair in pollen analysis in Nijmegen (1960). The botanical institute in Utrecht was Florschütz’ alma mater where he supervised students over two decades. Since 1947 Florschütz trained micropalaeontologists how to use fossil pollen as a biostratigraphical tool in oil industry. He inspired Jonker in Utrecht and Zagwijn in Leiden. Several of his students focused on tropical areas and used applied and academic pollen analysis to explore tropical ecosystems, such as Polak (1930s) and Muller (1950s) in southeast Asia, Van Zinderen Bakker (1950s) in southern Africa, Van der Hammen (1950s) in northern South America, Van Zeist and Bottema (1960s) in the Middle East. He stimulated Shell to be a pioneer in using pollen-based stratigraphy in oil exploration in the tropics. In the late 1940s and 1950s biostratigraphers Germeraad, Hopping, Kuyl, Muller and Waterbolk studied samples from the Caribbean, Nigeria and British Borneo in Shell’s Pollen Laboratories in Maracaibo (Venezuela) and in The Hague. In 1944 ‘pollen analysis’ was renamed ‘palynology’ for good reasons. Laboratory practice in applied research developed differently from academic palynology leading to a hybrid research field. Implications are briefly discussed.
A Proposal for Energy-Efficient Cellular Neural Network based on Spintronic Devices

description: Due to the massive parallel computing capability and outstanding image and signal processing performance, cellular neural network (CNN) is one promising type of non-Boolean computing system that can outperform the traditional digital logic computation and mitigate the physical scaling limit of the conventional CMOS technology. The CNN was originally implemented by VLSI analog technologies with operational amplifiers and operational transconductance amplifiers as neurons and synapses, respectively, which are power and area consuming. In this paper, we propose a hybrid structure to implement the CNN with magnetic components and CMOS peripherals with a complete driving and sensing circuitry. In addition, we propose a digitally programmable magnetic synapse that can achieve both positive and negative values of the templates. After rigorous performance analyses and comparisons, optimal energy is achieved based on various design parameters, including the driving voltage and the CMOS driving size. At a comparable footprint area and operation speed, a spintronic CNN is projected to achieve more than one order of magnitude energy reduction per operation compared to its CMOS counterpart.

description: This paper examines the reliability and the predictability of Soitec’s CPV technology by analyzing a
total of 149 months of AC energy and Direct-Normal Irradiance data acquired at three CPV power plants. Two of the
plants are located in Spain and have been in operation since 2008. The third plant is located in South Africa and has
been in operation since 2011. The reliability is quantified using the AC Performance Ratio and the Availability by
Yield as performance metrics. The predictability of the AC energy output is assessed by comparing the actual
measured AC energy with the target AC energy calculated with the PVsyst model, which utilizes the measured
meteorological data and the as-built power plant specifications as model input parameters.

description: Quality of Service (QoS) is provided in IEEE 802.11e protocol by means of HCF Controlled Channel Access (HCCA) scheduler which is efficient for supporting Constant Bit Rate (CBR) applications. Numerous researches have been carried out to enhance the HCCA scheduler attempting to accommodate the needs of Variable Bit Rate (VBR) video traffics which probably demonstrates a non-deterministic profile during the time. This paper presents an adaptive TXOP assignment mechanism for supporting the transmission of the prerecorded video traffics over IEEE 802.11e wireless networks. The proposed mechanism uses a feedback about the size of the subsequent video frames of the uplink traffic to assist the Hybrid Coordinator (HC) accurately assign TXOP according to the fast changes in the VBR profile. The simulation results show that our mechanism reduces the delay experienced by VBR traffic streams comparable to HCCA scheduler due to the accurate assignment of the TXOP which preserve the channel time for data transmission.

description: The pursuit of higher efficiency photovoltaic cells for terrestrial concentrator applications leads
naturally to consideration of 4-, 5-, and 6-junction cells. In this paper we investigate the semiconductor device
mechanisms affecting thermal performance of multijunction cells with more than 3 junctions. The temperature
dependences of 5-junction (5J) and 3-junction (3J) cells are modeled and compared, showing nearly identical relative
changes in the Voc and efficiency of 5J and 3J concentrator solar cells with varying temperature. A small increase in
Jsc as cell temperature rises is largely cancelled by a corresponding decrease in fill factor, both related to current
imbalance caused by shifting subcell bandgaps as temperature increases, while changes in Voc dominate the
multijunction cell efficiency temperature dependence. A formal treatment relating fractional change in Voc per °C to
the average subcell bandgap for any multijunction cell is developed, and compared to measured temperature
dependences of Voc for 1, 3, 4, and 5-junction cells, with inverted metamorphic (IMM), semiconductor bonding
technology (SBT), and upright lattice-matched (LM) cell designs. Intentional changes in subcell current balance are
studied, showing that 5J and 3J cells are remarkably insensitive to whether the subcells are designed to be current
balanced at 0°C, 50°C, or 100°C.

description: Statistical image reconstruction (SIR) methods are studied extensively for X-ray computed tomography (CT) due to the potential of acquiring CT scans with reduced X-ray dose while maintaining image quality. However, the longer reconstruction time of SIR methods hinders their use in X-ray CT in practice. To accelerate statistical methods, many optimization techniques have been investigated. Over-relaxation is a common technique to speed up convergence of iterative algorithms. For instance, using a relaxation parameter that is close to two in alternating direction method of multipliers (ADMM) has been shown to speed up convergence significantly. This paper proposes a relaxed linearized augmented Lagrangian (AL) method that shows theoretical faster convergence rate with over-relaxation and applies the proposed relaxed linearized AL method to X-ray CT image reconstruction problems. Experimental results with both simulated and real CT scan data show that the proposed relaxed algorithm (with ordered-subsets [OS] acceleration) is about twice as fast as the existing unrelaxed fast algorithms, with negligible computation and memory overhead.

description: Intermittent renewable energies present a big challenge specifically in the reliability of the electric
power grid operation. The increasing use of solar photovoltaic energy, among other renewables, in smart grids
requires the need of precise day-to-day and hour-to-hour weather forecast to prevent both power failures and
overloads and to manage the power share between the utilities. At the same time vendors need the most accurate
meteorological and power production forecasts for critical decision making in energy trading. With the purpose of
enhancing numerical weather prediction results through statistical post-processing based on real measurements, Ti-
Swiss, a meteorological consulting company, and the Institute of Sustainability to the Built Environment of the
University of Applied Sciences and Arts of Southern Switzerland (SUPSI-ISAAC) have started sharing the results of
their activity. In this work the authors compare the raw model and post-processed data with measurement data from
the meteorological tower located at the SUPSI-ISAAC outdoor test centre, as a result of a 1-year data analysis that
covers all seasonal variations in the environment under study.

description: In this paper, two grid connected photovoltaic systems are monitored. The first PV grid, is at CNRS-PROMES laboratory in Perpignan, built in 2001 with 3 PV arrays connected to the grid thanks to many inverters of different power (3 of 4KWC and 2 of 2.5KWC). The second one is at CNRS-LAAS in Toulouse with a power of 100kWc. It is composed of a facade of 36kWc PV array and a roof of 64kWc PV array. A monitoring device has been installed in order to measure electrical parameters and to detect behaviour drifts of these installations. This monitoring system is non intrusive and uses Transmission Control Protocol/Internet Protocol (TCPIP) for data sending (DC bus, AC bus, environmental data). This paper begins by a description of the monitoring system and PV systems. PV arrays are simulated using I-V characteristics of the cell implemented under Matlab/Simulink. An I-V characteristic is used to diagnose the type of the failure (soiling for example).
