description: Anthreptes malacensis iris Parkes Anthreptes malacensis iris Parkes, 1971: 44 (Sibutu Island). Now Anthreptes malacensis iris Parkes, 1971. See Dickinson et al., 1991: 507, and Cheke and Mann, 2008a: 247. HOLOTYPE: AMNH 685721, adult male, collected on Sibutu Island, 04.46N, 119.29E (Dickinson et al., 1991: 425), Sulu Archipelago, Philippines, in July 1893, by Alfred Everett. From the Rothschild Collection. COMMENTS: Parkes cited the AMNH number of the holotype in the original description and said that he had three specimens of iris from Sibutu. The two paratypes are: AMNH 685722, female, and AMNH 685723, unsexed, both collected on Sibutu in July 1893. Everett made a collection of birds in the Sulu Archipelago, including Sibutu Island, in July 1893, as reported on by Sharpe (1894). Sharpe (1894: 240–241) quoted a letter from Everett with information on his stay there and mentioned (on p. 251) that Everett had collected a series of ‘‘ Anthothreptes malaccensis ’’ on Sibutu. There is no indication that the three specimens from Sibutu that came to AMNH with the Rothschild Collection had been in the BMNH, and it is most likely that Rothschild obtained them later, either directly from Everett or from a dealer.

conventional grid, by performing experimental tests on a real system of the Laboratory of Hybrid Systems and
Microgrids, installed at the Group of Studies and Development of Energy Alternatives (GEDAE), Belém, Pará,
Brazil. The first test interconnects two different microgrids, the second test connects one microgrid to the
conventional grid, and the last test, once more, interconnects two different microgrids, but with a considerable
distance between their interconnection points. The experimental results obtained from these tests are presented and
explained, showing that the integration of the systems occurred as expected.

description: The energy sector is in a process of radical and unstoppable transformation, motivated by two reasons:
the fight against climate change and renewable energies. The two factors are decisive and go hand in hand, in line
with the social demands and decisions of the European Union to comply with the emission reduction agreements.
The growing increase in energy consumption in developed and developing countries is an important task that must be
addressed by the economic policies of these countries. The percentage of energy consumption of buildings relative to
the overall energy use has grown in the last years due to the increasing amount of electrical devices.
The photovoltaic windows as an integrated system in the building façades can contribute to generate clean energy to
meet needs of the inhabitants of these buildings.
A photovoltaic window specially built by a manufacturer has been studied. An amorphous silicon photovoltaic
module encapsulated between two transparent glass sheets, an air chamber and a second double glass sheet with an
air chamber forms the photovoltaic window. Everything is framed in a PVC structure. The effective dimensions of
the a-Si photovoltaic module are 0.57 m x 1.17 m, equivalent to a standard measurement of 0.60 m x 1.20 m.
To know the electrical characteristics of PV window in standard test conditions, a test in accordance with IEC
standard 61646 it was carried out. A peak power of 50.74 Wp was obtained.
Measurements of energy production in real sunlight were carried out. The window was placed vertically facing south
on a test bench. Measurements of the energy produced by the photovoltaic window were made in several sunny days
of August and September 2016 from sunrise to sunset. On average, the irradiance received on the plane of the
photovoltaic window was 4114 Wh/m2 and the energy produced 71.2 Wh each day. These results match those
obtained using the Malaga radiation databases.
For one square meter of the window studied, 79868 Wh/m2/year are obtained, when an overall efficiency of 0.8 is
considered. Integrating this PV window in a building in Malaga (Spain), an annual electric production of 345030
kWh is obtained when a glazing surface of 4320 m2 is considered. This energy is enough to meet the annual
electricity needs of the 68 household of the building. Furthermore, the saving in electricity bill of the houses of the
building would be 59279 €/year and the BIPV system would avoid the emission of 240278 kg of CO2 into the
atmosphere per year.

description: 35th European Photovoltaic Solar Energy Conference and Exhibition; 1833-1837
description: Building integrated photovoltaic (BIPV) technology has experienced a significant development over
the most recent years. Yet some barriers to its large deployment remain. One of them is the lack of design
consideration regarding the installation of BIPV modules. This paper demonstrates the technical feasibility of a
curtain wall BIPV concept that steps towards the plug-and-play concept to facilitate the installation process. A
prototype of such BIPV concept was constructed and installed in the façade of a real building, considering the
technical requirements for building components. The BIPV module has been operating for over a year. Between
August 2017 and July 2018, the BIPV module operated with monthly PR-values between 88 and 99%, and an
average of 94.2%. The yearly PR was 92.6%. Furthermore, a Finite Element Method (FEM) model was developed in
COMSOL to investigate the thermal behaviour of the module. Comparison against experimental data showed that the
model is able to predict the BIPV temperature over time. This model will be useful in future studies to (1) optimize
the BIPV module design in terms of thermal performance, and (2) investigate the suitability of integrating power
electronic components inside the module’s frame in order to achieve a fully plug-and-play system.
Decomposition of integer-valued polynomial algebras

description: Let $D$ be a commutative domain with field of fractions $K$, let $A$ be a torsion-free $D$-algebra, and let $B$ be the extension of $A$ to a $K$-algebra. The set of integer-valued polynomials on $A$ is ${\rm Int}(A) = \{f \in B[X] \mid f(A) \subseteq A\}$, and the intersection of ${\rm Int}(A)$ with $K[X]$ is ${\rm Int}_K(A)$, which is a commutative subring of $K[X]$. The set ${\rm Int}(A)$ may or may not be a ring, but it always has the structure of a left ${\rm Int}_K(A)$-module. A $D$-algebra $A$ which is free as a $D$-module and of finite rank is called ${\rm Int}_K$-decomposable if a $D$-module basis for $A$ is also an ${\rm Int}_K(A)$-module basis for ${\rm Int}(A)$; in other words, if ${\rm Int}(A)$ can be generated by ${\rm Int}_K(A)$ and $A$. A classification of such algebras has been given when $D$ is a Dedekind domain with finite residue rings. In the present article, we modify the definition of ${\rm Int}_K$-decomposable so that it can be applied to $D$-algebras that are not necessarily free by defining $A$ to be ${\rm Int}_K$-decomposable when ${\rm Int}(A) \cong {\rm Int}_K(A) \otimes_D A$. We then provide multiple characterizations of such algebras in the case where $D$ is a discrete valuation ring or a Dedekind domain with finite residue rings. In particular, if $D$ is the ring of integers of a number field $K$, we show that ${\rm Int}_K$-decomposable algebras $A$ correspond to maximal $D$-orders in a separable $K$-algebra $B$, whose simple components have as center the same finite unramified Galois extension $F$ of $K$ and are unramified at each finite place of $F$. Finally, when both $D$ and $A$ are rings of integers in number fields, we show that ${\rm Int}_K$-decomposable algebras correspond to unramified Galois extensions of $K$.

description: Although a lot of approaches are developed to release network data with a differentially privacy guarantee, inference using noisy data in many network models is still unknown or not properly explored. In this paper, we release the bi-degree sequences of directed networks using the Laplace mechanism and use the $p_0$ model for inferring the degree parameters. The $p_0$ model is an exponential random graph model with the bi-degree sequence as its exclusively sufficient statistic. We show that the estimator of the parameter without the denoised process is asymptotically consistent and normally distributed. This is contrast sharply with some known results that valid inference such as the existence and consistency of the estimator needs the denoised process. Along the way, a new phenomenon is revealed in which an additional variance factor appears in the asymptotic variance of the estimator when the noise becomes large. Further, we propose an efficient algorithm for finding the closet point lying in the set of all graphical bi-degree sequences under the global $L_1$ optimization problem. Numerical studies demonstrate our theoretical findings.

description: In this paper we study non-linear noise excitation for the following class of space-time fractional stochastic equations in bounded domains: $$\partial^β_tu_t(x)=-ν(-Δ)^{α/2} u_t(x)+I^{1-β}_t[λσ(u)\stackrel{\cdot}{F}(t,x)]$$ in $(d+1)$ dimensions, where $ν>0, β\in (0,1)$, $α\in (0,2]$. The operator $\partial^β_t$ is the Caputo fractional derivative, $-(-Δ)^{α/2} $ is the generator of an isotropic stable process and $I^{1-β}_t$ is the fractional integral operator. The forcing noise denoted by $\stackrel{\cdot}{F}(t,x)$ is a Gaussian noise. The multiplicative non-linearity $σ:\RR{R}\to\RR{R}$ is assumed to be globally Lipschitz continuous. These equations were recently introduced by Mijena and Nane(J. Mijena and E. Nane. Space time fractional stochastic partial differential equations. Stochastic Process Appl. 125 (2015), no. 9, 3301--3326). We first study the existence and uniqueness of the solution of these equations {and} under suitable conditions on the initial function, we {also} study the asymptotic behavior of the solution with respect to the parameter $λ$. In particular, our results are significant extensions of those in Foondun et al (M. Foondun, K. Tian and W. Liu. On some properties of a class of fractional stochastic equations. Preprint available at arxiv.org 1404.6791v1.), Foondun and Khoshnevisan (M. Foondun and D. Khoshnevisan. Intermittence and nonlinear parabolic stochastic partial differential equations, Electron. J.

description: In this paper, we use Kansa method for solving the system of differential equations in the area of biology. One of the challenges in Kansa method is picking out an optimum value for Shape parameter in Radial Basis Function to achieve the best result of the method because there are not any available analytical approaches for obtaining optimum Shape parameter. For this reason, we design a genetic algorithm to detect a close optimum Shape parameter. The experimental results show that this strategy is efficient in the systems of differential models in biology such as HIV and Influenza. Furthermore, we prove that using Pseudo-Combination formula for crossover in genetic strategy leads to convergence in the nearly best selection of Shape parameter.

description: The origin of rigidity in disordered materials is an outstanding open problem in statistical physics. Previously, a class of 2D cellular models has been shown to undergo a rigidity transition controlled by a mechanical parameter that specifies cell shapes. Here, we generalize this model to 3D and find a rigidity transition that is similarly controlled by the preferred surface area: the model is solid-like below a dimensionless surface area of $s_0^\ast\approx5.413$, and fluid-like above this value. We demonstrate that, unlike jamming in soft spheres, residual stresses are necessary to create rigidity. These stresses occur precisely when cells are unable to obtain their desired geometry, and we conjecture that there is a well-defined minimal surface area possible for disordered cellular structures. We show that the behavior of this minimal surface induces a linear scaling of the shear modulus with the control parameter at the transition point, which is different from the scaling observed in particulate matter. The existence of such a minimal surface may be relevant for biological tissues and foams, and helps explain why cell shapes are a good structural order parameter for rigidity transitions in biological tissues.

description: The Faroe Islands form a group of 18 islands located in the North Atlantic at 62° N. They are populated with about 51,000 people. The capital city, Tórshavn has about 21,000 inhabitants. Currently, the energy supply is given on the electricity side by a mix of fossil fired power stations, hydropower plants and wind farms. The heating sectors are mainly based on oil burners. This is the reason to restructure the energy supply to abandon the use of fossil fuels by 2030. There is an ongoing discussion on the best option to reach this goal. First scenarios had been set up. This paper aims to contribute to this discussion by highlighting the options of the inclusion of PV power at this location.

description: The theoretical description and the survey of physical properties of superconducting states in the uranium ferromagnetic materials are presented. On the basis of microscopic theory is shown that the coupling between the electrons in these ferromagnetic metals by means of magnetization fluctuations gives rise the triplet pairing superconducting state and the general form of the order parameter dictated by the symmetry is established. The theory allows to explain some specific observations including peculiar phenomenon of reentrant superconductivity in URhGe in magnetic field perpendicular to the direction of spontaneous magnetization. In addition we describe several particular topics relating to uranium superconducting ferromagnets: (i) critical magnetic relaxation in dual localized-itinerant ferromagnets, (ii) phase transition to ferromagnetic state in Fermi liquid and UGe$_2$, (iii) superconducting ordering in ferromagnetic metals without inversion symmetry.

description: The subject of this paper are expert systems from which especially users of LID- (libraries, information and documentation) institutions are supposed to benefit. An expert system is defined as a program that within a specified field allows reproducing expertise and the expert's capability of drawing conclusions. The first part of this paper consists of an introduction to these systems and their classifcation within the higher field of artificial intelligence. In the following part the theoretical possibilities of using these expert systems in the LID-sector and the practical systems developed for users are described. The investigation of the dissemination of expert systems is conducted through examples and a following statistical analysis of the results. Interviews at several LID institutions in Berlin are included. As an overall result it can be stated that the problems which have arised in connection with the operation of expert systems have led to a re-orientation in academic research.

We investigate when Abel-Jacobi faces are non-trivial, and we prove that for $d$ sufficiently large (with respect to the genus of $C$) they form a maximal chain of perfect faces of the tautological pseudoeffective cone (which coincides with the pseudoeffective cone if $C$ is a very general curve).

description: Nowadays, PV modules are almost identical in size and shape and weight worldwide. Standard
photovoltaic modules, therefor, show 60 or 72 Si wafer based cell layout, interconnected string-wise and all
embedded within an encapsulant material (e.g. Ethylen-Vinylacetat (EVA)) and between a frontglass and a polymeric
backsheet. In terms of new applications and up-coming trends in the photovoltaic sector, certain material restrictions
as well as size and weight requirements can show up. Examples for such applications are building-integrated
photovoltaics (BIPV), vehicle-integrated photovoltaics (VIPV) or comparable mobile implementations, for which low
transportation/installation weight is a crucial aspect, e.g. off-grid and solar home system markets.
By this paper, we want to discuss parameters for alternative photovoltaic module classifications, in order to get the
ability to compare and separate modules in regards of lightweight and design aspects and underlying technology. The
parameters Power-to-Weight Ratio P2W, Area density AD, Weight-to-Power Ratio W2P and Efficiency-to-Weight
Ratio E2W are proposed to compare the three module groups Silicon, ThinFilm and Lightweight.

description: Recently the most general completion of Brans-Dicke theory was appeared with energy exchanged between the scalar field and ordinary matter, given that the equation of motion for the scalar field keeps the simple wave form of Brans-Dicke. This class of theories contain undetermined functions, but there exist only three theories which are unambiguously determined from consistency. Here, for the first such theory, it is found the action of the vacuum theory which arises as the limit of the full matter theory. A symmetry transformation of this vacuum action in the Jordan frame is found which consists of a conformal transformation of the metric together with a redefinition of the scalar field. Since the general family of vacuum theories is parametrized by an arbitrary function of the scalar field, the action of this family is also found. As for the full matter theory it is only found the action of the system when the matter Lagrangian vanishes on-shell, as for example for pressureless dust. Due to the interaction, this matter Lagrangian is non-minimally coupled either in the Jordan or the Einstein frame.

See Dickinson et al., 1991: 379–380, and Cheke and Mann, 2008a: 267–268. HOLOTYPE: AMNH 348777, adult male, collected at Lamao, 14.31N, 120.36E (Dickinson et al., 1991: 420), Bataan Province, Luzon Island, Philippines, on 30 November 1947, by Manuel Celestino. COMMENTS: Gilliard cited the AMNH number of the holotype in the original description and noted that he collected an additional male, one immature male, and two adult females. The collection was divided between AMNH and PNM (Gilliard, 1950: 463) before the AMNH portion was cataloged. The paratypes in AMNH are: AMNH 459631, adult male, and AMNH 459632, adult female, both collected at Lamao. The other adult female and the immature male, presumably in PNM, are also paratypes.

description: Current fluctuations in boundary-driven diffusive systems are, in many cases, studied using hydrodynamic theories. Their predictions are then expected to be valid for currents which scale inversely with the system size. To study this question in detail, we introduce a class of large-N models of one-dimensional boundary-driven diffusive systems, whose current large deviation functions are exactly derivable for any finite number of sites. Surprisingly, we find that for some systems the predictions of the hydrodynamic theory may hold well beyond their naive regime of validity. Specifically, we show that, while a symmetric partial exclusion process exhibits non-hydrodynamic behaviors sufficiently far beyond the naive hydrodynamic regime, a symmetric inclusion process is well described by the hydrodynamic theory for arbitrarily large currents. We conjecture, and verify for zero-range processes, that the hydrodynamic theory captures the statistics of arbitrarily large currents for all models where the mobility coefficient as a function of density is unbounded from above. In addition, for the large-N models, we prove the additivity principle under the assumption that the large deviation function has no discontinuous transitions.

description: Humans use signs, e.g., sentences in a spoken language, for communication and thought. Hence, symbol systems like language are crucial for our communication with other agents and adaptation to our real-world environment. The symbol systems we use in our human society adaptively and dynamically change over time. In the context of artificial intelligence (AI) and cognitive systems, the symbol grounding problem has been regarded as one of the central problems related to {\it symbols}. However, the symbol grounding problem was originally posed to connect symbolic AI and sensorimotor information and did not consider many interdisciplinary phenomena in human communication and dynamic symbol systems in our society, which semiotics considered. In this paper, we focus on the symbol emergence problem, addressing not only cognitive dynamics but also the dynamics of symbol systems in society, rather than the symbol grounding problem. We first introduce the notion of a symbol in semiotics from the humanities, to leave the very narrow idea of symbols in symbolic AI. Furthermore, over the years, it became more and more clear that symbol emergence has to be regarded as a multifaceted problem. Therefore, secondly, we review the history of the symbol emergence problem in different fields, including both biological and artificial systems, showing their mutual relations. We summarize the discussion and provide an integrative viewpoint and comprehensive overview of symbol emergence in cognitive systems. Additionally, we describe the challenges facing the creation of cognitive systems that can be part of symbol emergence systems.

description: One feasible design for Building-Integrated Photovoltaic modules applies ceramic printed glass covers. Power prediction of such modules is difficult as transmittance of printed glass panes in air was shown to be much lower than the relative power loss in the respective modules for the same print coverage ratio. Applying a matrix-based approach, we developed a light attenuation model, which can describe the relative transmittance decrease of glass panes in air and relative power decrease of modules for glass covers with arbitrary coverage ratios. The model shows good correlation with measured data. The modelled transmittance of glass panes deviate with a root mean square error of 0.55% from the measured transmittance values. The model can compute the module performance loss for investigated coverage ratios with a RMSE of 0.73%.

description: We report GHz longitudinal as well as shear acoustic phonons photoexcitation and photodetection using femtosecond laser pulses in a spin-crossover molecular crystal. From our experimental observation of time domain Brillouin scattering triggered by the photoexcitation of acoustic waves across the low-spin (LS) to high-spin (HS) thermal crossover, we reveal a link between molecular spin state and photoexcitation of coherent GHz acoustic phonons. In particular, we experimentally evidence an unconventional non-thermal pathway for the laser excitation of GHz phonons. We also provide experimental insight on the optical and mechanical parameters evolution across the LS/HS spin crossover temperature T$_{1/2}$.

description: Video continues to dominate network traffic, yet operators today have poor visibility into the number, duration, and resolutions of the video streams traversing their domain. Current approaches are inaccurate, expensive, or unscalable, as they rely on statistical sampling, middle-box hardware, or packet inspection software. We present {\em iTelescope}, the first intelligent, inexpensive, and scalable SDN-based solution for identifying and classifying video flows in real-time. Our solution is novel in combining dynamic flow rules with telemetry and machine learning, and is built on commodity OpenFlow switches and open-source software. We develop a fully functional system, train it in the lab using multiple machine learning algorithms, and validate its performance to show over 95\% accuracy in identifying and classifying video streams from many providers including Youtube and Netflix. Lastly, we conduct tests to demonstrate its scalability to tens of thousands of concurrent streams, and deploy it live on a campus network serving several hundred real users. Our system gives unprecedented fine-grained real-time visibility of video streaming performance to operators of enterprise and carrier networks at very low cost.

description: Our goal is to unravel the mechanisms that lead to failure of a ductile two-phase material - that consists of a ductile soft phase and a relatively brittle hard phase. An idealized microstructural model is used to study damage propagation systematically and transparently. The analysis uncovers distinct microstructural features around early voids, whereby regions of the hard phase are aligned with the tensile axis and regions of the soft phase are aligned with the shear directions. These features are consistently found in regions exhibiting damage propagation, whereby the damage remains initiation driven, i.e. voids nucleate independently of each other. Upon localization, damage is controlled on a longer length-scale relying on a critical relative position of 'initiation hot-spots'. The damage rapidly increases in bands of the soft phase wherein several voids are aligned with the shear directions. The relative arrangement of the voids determines whether the microstructure fails early, or at a substantially higher strain. Although much research is needed to refine these findings for real or more realistic microstructures, in particular in three-dimensions, this paper opens a route to a deeper understanding of the ultimate failure of multi-phase materials.

Solar Resource and Forecasting

description: 35th European Photovoltaic Solar Energy Conference and Exhibition; 1770-1773
description: In this paper a new procedure for nowcasting solar irradiation is proposed. The procedure is based on
an improved version of the two-state model for nowcasting solar irradiance at ground level. Principally, the procedure
sums-up the solar irradiance forecasts generated by the two state-model at one-minute sampling of the lead time. The
proposed procedure demonstrates a better performance than the main competitor based on ARIMA forecasting of the
clearness index. The study was conducted with high-quality radiometric data measured on the Solar Platform of the
West University of Timisoara at a high frequency of four samples per minute.
