description: In the development of next-generation power modules for electric vehicles, demands for high efficiency, reliability, low cost, high power density and therefore small size are of major importance. A promising approach is the embedding of power semiconductor devices into a printed circuit board (PCB), as investigated by the HI-LEVEL project. This paper deals with the research, design and experimental verification of a current sensor based on the principle of a Rogowski coil, which is integrated into a PCB, so that it can measure the device current of the embedded power semiconductor devices. As switched-mode currents are to be measured, the dynamics of the current sensor were of major concern. Moreover, as large voltage gradients caused by the semiconductor devices inject parasitic capacitive currents into the coil, a differential measurement approach was selected for cancelling out disturbances caused by capacitive coupling.

description: With increasing integration of the intermittent and volatile renewable energy resources into the existing ac grid infrastructure, the grid stability is decreasing. Large battery storage systems are proposed to act as short-time buffer to cope with transient instabilities. A promising converter to interface such low-voltage high-power battery banks is the T-type Neutral- Point-Clamped Converter (TNPC). A generalized implementation of a variant of the well-known space vector modulation featuring lower losses is proposed in this work. The derived relations to select a particular switching sequence are based on the binary logic and symmetry of the possible states in such a three-level converter. The algorithm proposed in this work dynamically adjusts the switching sequences to accommodate capacitive as well as inductive behavior.

description: Symmetries in quantum mechanics are realized by the projective representations of the Lie group as physical states are defined only up to a phase. A cornerstone theorem shows that these representations are equivalent to the unitary representations of the central extension of the group. The formulation of the inertial states of special relativistic quantum mechanics as the projective representations of the inhomogeneous Lorentz group, and its nonrelativistic limit in terms of the Galilei group, are fundamental examples. Interestingly, neither of these symmetries includes the Weyl-Heisenberg group; the hermitian representations of its algebra are the Heisenberg commutation relations that are a foundation of quantum mechanics. The Weyl-Heisenberg group is a one dimensional central extension of the abelian group and its unitary representations are therefore a particular projective representation of the abelian group of translations on phase space. A theorem involving the automorphism group shows that the maximal symmetry that leaves invariant the Heisenberg commutation relations are essentially projective representations of the inhomogeneous symplectic group. In the nonrelativistic domain, we must also have invariance of Newtonian time. This reduces the symmetry group to the inhomogeneous Hamilton group that is a local noninertial symmetry of Hamilton's equations. The projective representations of these groups are calculated using the Mackey theorems for the general case of a nonabelian normal subgroup.

description: The erbium atomic system is a promising candidate for an atomic Bose-Einstein condensate of atoms with a non-vanishing orbital angular momentum ($L \neq 0$) of the electronic ground state. In this paper we report on the frequency stabilization of a blue external cavity diode laser system on the 400.91 $nm$ laser cooling transition of atomic erbium. Doppler-free saturation spectroscopy is applied within a hollow cathode discharge tube to the corresponding electronic transition of several of the erbium isotopes. Using the technique of frequency modulation spectroscopy, a zero-crossing error signal is produced to lock the diode laser frequency on the atomic erbium resonance. The latter is taken as a reference laser to which a second main laser system, used for laser cooling of atomic erbium, is frequency stabilized.

description: We have discovered a number of relatively strong radio sources in the field-of-view of SDSS galaxy clusters which present no optical counterparts down to the magnitude limits of the SDSS. The optically faint radio sources appear as double-lobed or core-jet objects on the FIRST radio images and have projected angular sizes ranging from 0.5 to 1.0 arcmin. We have followed-up these sources with near-infrared imaging using the wide-field imager HAWK-I on the VLT. K_s-band emitting regions, about 1.5 arcsec in size and coincident with the centers of the radio structures, were detected in all the sources, with magnitudes in the range 17-20 mag. We have used spectral modelling to characterize the sample sources. In general, the radio properties are similar to those observed in 3CRR sources but the optical-radio slopes are consistent with moderate to high redshift (z<4) gigahertz-peaked spectrum sources. Our results suggest that these unusual objects are galaxies whose black hole has been recently re-ignited but retain large-scale radio structures, signatures of previous AGN activity.

description: Recently, 60Fe was found in the Earth crust formed in a nearby recent supernova (SN). If the distance to the SN and mass of the progenitor of that SN was known, then one could constrain SN models. Knowing the positions, proper motions, and distances of dozens of young nearby neutron stars, we can determine their past flight paths and possible kinematic origin. Once the birth place of a neutron star in a SN is found, we would have determined the distance of the SN and the mass of the SN progenitor star.

Self Heating of Corona by Electrostatic Fields Driven by Sheared Flows

description: A mechanism of self-heating of solar corona is pointed out. It is shown that the free energy available in the form of sheared flows gives rise to unstable electrostatic waves which accelerate the particles and heat them. The electrostatic perturbations take place through two processes (a) by purely growing sheared flow-driven instability and (b) by sheared flow-driven drift waves. These processes occur throughout the corona and hence the self-heating is very important in this plasma. These instabilities can give rise to local electrostatic potentials $φ$ of the order of about 100 volts or less within $3\times10^{-2}$ to a few seconds time if the initial perturbation is assumed to be about one percent that is $\frac{eφ}{T_{e}}\simeq10^{-2}$. The components of wave lengths in the direction perpendicular to external magnetic field $\textbf{B}_{0}$ vary from about 10m to 1m. The purely growing instability creates electrostatic fields by sheared flows even if the density gradient does not exist whereas the density gradient is crucial for the concurrence of drift wave instability. Subject headings: Sun: self-heating of corona, sheared flow-driven instability, drift waves.

description: The demand for increased transmission capacities in Germany will be covered in part by high voltage direct current (HVDC) lines. In order to reduce the need for new corridors, hybrid systems with AC and DC circuits together on the same tower are planned. Therefore, the characteristics of such arrangements need to be studied. In the first part of this paper, electromagnetic coupling mechanisms between overhead lines are summarized. Next, the method of image charges as a way to calculate the electric field around overhead lines is presented. The method is then used to analyze the electric field on ground level below three different hybrid line configurations.

description: Wind power fluctuates with time and it is reasonable to regard it as a random variable. Recently, an active-reactive optimal power flow (A-R-OPF) method in active distribution networks with wind stations has been developed to handle the problem of wind power curtailment (WPC). Since the mentioned method is deterministic, it may fail to handle uncertain wind power (UWP). Therefore, our study in this paper will firstly discuss the issue of UWP and secondly develop a new strategy which can improve the A-R-OPF by considering UWP. The new strategy can be distinguished from the original so that: 1) it considers shorter time intervals, i.e., 15 minutes instead of one hour and 2) it can handle both UWP and WPC simultaneously. The effectiveness of the new strategy is shown by using a real case medium-voltage distribution network.

description: We clarify the role of quantum-well states in magnetic trilayer systems from majority carrier in the ferromagnetic and all carriers in the antiferromagnetic configurations. In addition to numerical and analytic calculations, heuristic pictures are provided to explain effects of a capping layer and side-layer modulation in recent experiments. This immediately offers answers to two unexplained subtle findings in experiments and band-structure calculations, individually. Furthermore, it allows a more flexible tuning of or even turning off the interlayer exchange coupling.

description: Durch die Forderung nach einer natürlichen Lüftung von Bürogebäuden und einem effektiven Sonnenschutz in Hochhäusern haben Doppelfassaden einen hohen Stellenwert erreicht. Das energetische Verhalten von Doppelfassaden ist Gegenstand zahlreicher Veröffentlichungen. Bisher liegen jedoch nur wenige Messungen in ausgeführten Gebäuden vor.Im Rahmen dieser Arbeit wurden drei Gebäude mit Doppelfassaden detailliert vermessen. Die Langzeitmessungen erfassten über mindestens ein Jahr unter anderem die Temperaturen im Raum und in der Doppelfassade, die Luftströmung in der Fassade, Wärmeflüsse und meteorologische Randbedingungen. Gemessen wurde in einem Hochhaus ohne Haustechnik für Lüftung und Kühlung (Siemens-Gebäude in Dortmund), einem Hochhaus mit Lüftungsanlage und Kühldecke (RWE-Turm in Essen) und einem Gebäude mit Betonkerntemperierung (Victoria Versiche-rung in Düsseldorf).Ausgewertet dargestellt werden unter anderem jeweils eine Sommerperiode, eine Winterperiode, die Temperaturüberschreitungsdauern im Raum und in der Fassade für ein Jahr und punktuelle Messungen des Raumluftwechsels.Für die Auslegung und die Simulation von Doppelfassaden ist die Luftströmung im Fassadenzwischenraum bisher die einzige schwer zu bestimmende Größe. Der Luftaustausch in der Fassade wurde über eine energetische Bilanz anhand der gemessenen Strömungsgeschwindigkeiten kalibriert. Eine statistische Auswertung der Messdaten zeigt einen signifikanten Einfluss von Windgeschwindigkeit, Wind-richtung und der Temperaturdifferenz zwischen Fassadenzwischenraum und Umge-bung.Trotz aller Unterschiede in der Fassaden-gestaltung stellt sich für die ausgewerteten Gebäude ein linearer Zusammenhang zwischen dem wirksamen Öffnungsanteil der Außenfassade und dem mittleren Luftvolumen-strom pro m² Fassadenfläche in der Fassade ein.Mit Hilfe der durchgeführten Langzeitmessungen in drei Gebäuden können die energetischen Zusammenhänge klar beschrieben und die Grenzen und Möglichkeiten von Doppelfassaden aufgezeigt werden.

description: The k=0 Friedmann Lemaitre Robertson Walker model with a positive cosmological constant and a massless scalar field is analyzed in detail. If one uses the scalar field as relational time, new features arise already in the Hamiltonian framework of classical general relativity: In a finite interval of relational time, the universe expands out to infinite proper time and zero matter density. In the deparameterized quantum theory, the true Hamiltonian now fails to be essentially self-adjoint both in the Wheeler DeWitt (WDW) approach and in LQC. Irrespective of the choice of the self-adjoint extension, the big bang singularity persists in the WDW theory while it is resolved and replaced by a big bounce in loop quantum cosmology (LQC). Furthermore, the quantum evolution is surprisingly insensitive to the choice of the self-adjoint extension. This may be a special case of an yet to be discovered general property of a certain class of symmetric operators that fail to be essentially self-adjoint.

description: (Abridged). The optical light curve of some SNe may be powered by the outward diffusion of the energy deposited by the explosion shock in optically thick circumstellar matter (CSM). Recently, it was shown that the radiation-mediated and -dominated shock in an optically thick wind must transform into a collisionless shock and can produce hard X-rays. The X-rays are expected to peak at late times, relative to maximum visible light. Here we report on a search, using Swift and Chandra, for X-ray emission from 28 SNe that belong to classes whose progenitors are suspected to be embedded in dense CSM (IIn/Ibn/SLSN-I). Two SNe in our sample have X-ray properties that are roughly consistent with the expectation for X-rays from a collisionless shock in optically thick CSM. Therefore, we suggest that their optical light curves are powered by shock breakout in CSM. We show that two other events were too X-ray bright during the SN maximum optical light to be explained by the shock breakout model. We conclude that the light curves of some, but not all, type-IIn/Ibn SNe are powered by shock breakout in CSM. For the rest of the SNe in our sample, including all the SLSN-I events, our X-ray limits are not deep enough and were typically obtained at too early times to conclude about their nature. We argue that the optical light curves of SNe, for which the X-ray emission peaks at late times, are likely powered by the diffusion of shock energy from a dense CSM. We comment about the possibility to detect some of these events in radio.

description: Herschel images in six photometric bands show the thermal emission of the debris disk surrounding beta Pic. In the three PACS bands at 70 micron, 100 micron and 160 micron and in the 250 micron SPIRE band, the disk is well-resolved, and additional photometry is available in the SPIRE bands at 350 micron and 500 micron, where the disk is only marginally resolved. The SPIRE maps reveal a blob to the southwest of beta Pic, coinciding with submillimetre detection of excess emission in the disk. We investigated the nature of this blob. Our comparison of the colours, spectral energy distribution and size of the blob, the disk and the background sources shows that the blob is most likely a background source with a redshift between z =1.0 and z = 1.6.

description: The mass spectra of charmonia, bottomonia and B_c mesons are calculated in the framework of the QCD-motivated relativistic quark model based on the quasipotential approach. The dynamics of heavy quarks and antiquarks is treated fully relativistically without application of the nonrelativistic v^2/c^2 expansion. The known one-loop radiative corrections to the heavy quark potential are taken into account perturbatively. The heavy quarkonium masses are calculated up to rather high orbital and radial excitations (L=5, n_r=5). On this basis the Regge trajectories are constructed both in the total angular momentum J and radial quantum number n_r. It is found that the daughter trajectories are almost linear and parallel, while parent trajectories exhibit some nonlinearity in the low mass region. Such nonlinearity is most pronounced for bottomonia and is only marginal for charmonia. The obtained results are compared with the available experimental data, and a possible interpretation of the new charmonium-like states above open charm production threshold is discussed.

description: Due to the increase in electricity production from renewable energy sources, the share of volatile electricity supply rises in German distribution networks. Since these networks are, for historical reasons, not designed for the supply of distributed generation, this already leads to an overloading of the network resources, today. In this work, different distributed generation management concepts are presented, which should avoid this overloading by temporarily reducing the power supply. To simulate these methods, the supply from solar, wind, biomass and cogeneration power plants is modeled. The implementation of these distributed generation management concepts depends on the available information from measurement points. Finally, an evaluation of the different generation management methods is made, taking the implementing

description: We analyze the quantum discord Q throughout the low-temperature phase diagram of the quantum XY model in transverse field. We first focus on the T=0 order-disorder quantum phase transition both in the symmetric ground state and in the symmetry broken one. Besides it, we highlight how Q displays clear anomalies also at a non critical value of the control parameter inside the ordered phase, where the ground state is completely factorized. We evidence how the phenomenon is in fact of collective nature and displays universal features. We also study Q at finite temperature. We show that, close to the quantum phase transition, Q exhibits quantum-classical crossover of the system with universal scaling behavior. We evidence a non trivial pattern of thermal correlations resulting from the factorization phenomenon.

subject: 620

description: In this article, the algorithm of reliability evaluation of electricity supply systems operation is presented. It includes evaluation of the reliability of consumer’s electricity supply and the reliability of power generation by the local power plants. Proposed algorithm is based on the method of sequential network reduction and allows calculating the reliability indices of the selected consumer or of the certain point of power distribution. This algorithm is implemented in the program complex (PC) KATRAN. The calculation of reliability indices allows assessing the consumer’s outage cost and the interruption costs of the enterprise’s power plants.

Can overturning motions in penumbral filaments be detected?

description: Numerical simulations indicate that the filamentation of sunspot penumbrae and the associated systematic outflow (the Evershed effect) are due to convectively driven fluid motions constrained by the inclined magnetic field. We investigate whether these motions, in particular the upflows in the bright filaments and the downflows at their edges can be reliably observed with existing instrumentation. We use a snapshot from a sunspot simulation to calculate 2D maps of synthetic line profiles for the spectral lines Fe\sci 7090.4 Å~ and C\sci 5380.34 Å. The maps are spatially and spectrally degraded according to typical instrument properties. Line-of-sight velocities are determined from line bisector shifts. We find that the detectability of the convective flows is strongly affected by spatial smearing, particularly so for the downflows. Furthermore, the line-of-sight velocities are dominated by the Evershed flow unless the observation is made very near to disk center. These problems may have compromised recent attempts to detect overturning penumbral convection. Lines with a low formation height are best suited to detect the convective flows.

description: Durch die Umstrukturierung von Mittelspannungsnetzen in Deutschland sowie durch die Veröffentlichungs- und Ausschreibepflicht von Netzverlusten bekommt die Optimierung von Energieversorgungsnetzen mehr und mehr an Bedeutung. Dieser Beitrag befasst sich mit der Optimierung von einem Mittelspannungsnetz, welches durch verschiedene Spannungsebenen (110 kV und 30 kV) gespeist wird. Durch ein erhöhtes Anlagenalter der 30-kV-Betriebsmittel, soll überprüft werden ob die Möglichkeit besteht ein Umspannwerk 30/10 kV durch eine 10-kV-Stützpunktstation zu ersetzten. Hierzu werden zwei Varianten entwickelt und mit der Netzberechnungs- und Simulationssoftware PSS®Sincal hinsichtlich der Netzverluste untersucht. Als Vergleichsnetz wird ebenfalls auch das Ursprungsmittelspannungsnetz herangezogen, und untersucht welche Betriebsmittels zu ersetzen sind. Als weiterer Ansatzpunkt wer-den die ungefähren Kosten für die beiden Varianten und den Weiterbetrieb des Netzes aufgestellt.

description: Most of the intrusion detection systems in the market are signature-based making the process of discovering new intrusions a big challenge. Hence, in literature techniques of machine learning have been proposed as a solution to improve the accuracy of signature-based methods [1]. However, the machine learning techniques must be adopted in order to improve the IDS in identifying the existing malware or to discover new ones. Different factors should be taking into account when applying these techniques such as the dataset size and the presented features in the dataset because they play a crucial role in the overall system efficiency [2]. In cases when irrelevant features are present in the dataset, the machine learning techniques can lead to different errors such as classification misleading, overfitting, generality reduction, model run-time enhancement and processing complexity. When it comes to SMEs, one of the challenges faced in the IDSs is the presence of high false alarm rate, resulting to a high workload for their employees. SMEs should have in place IDSs in order to reduce the streamline and improve system accuracy. There is a need for SMEs to apply machine learning techniques to reduce and streamline the intrusion detection process. The most important task performed by an IDS is the classifications of attack in different classes which can be performed using different machine learning techniques that has to be properly tuned and not blindly applied to reduce system complexity and to increase system performance. In this paper, we are investigating the different machine learning techniques used in the context of IDSs to ascertain the potential presence of any technique which can be used for IDS for SMEs. Many researchers concluded that the classification techniques are inappropriate in unbalanced dataset failing to effectively identify the attacks types. This paper explains the most widely used machine learning techniques for intrusion detection systems addressing the challenges faced in SME.

description: Three pion dominated observables of the parity nonconserving interactions between the cold neutrons and parahydrogen are calculated. The transversely polarized neutron spin rotation, unpolarized neutron longitudinal polarization, and photon-asymmetry of the radiative polarized neutron capture are considered. For the numerical evaluation of the observables, the strong interactions are taken into account by the Reid93 potential and the parity nonconserving interactions by the DDH model along with the two-pion exchange.

description: The lunar geological record has much to tell us about the earliest history of the Solar System, the origin and evolution of the Earth-Moon system, the geological evolution of rocky planets, and the near-Earth cosmic environment throughout Solar System history. In addition, the lunar surface offers outstanding opportunities for research in astronomy, astrobiology, fundamental physics, life sciences and human physiology and medicine. This paper provides an interdisciplinary review of outstanding lunar science objectives in all of these different areas. It is concluded that addressing them satisfactorily will require an end to the 40-year hiatus of lunar surface exploration, and the placing of new scientific instruments on, and the return of additional samples from, the surface of the Moon. Some of these objectives can be achieved robotically (e.g. through targeted sample return, the deployment of geophysical networks, and the placing of antennas on the lunar surface to form radio telescopes). However, in the longer term, most of these scientific objectives would benefit significantly from renewed human operations on the lunar surface. For these reasons it is highly desirable that current plans for renewed robotic surface exploration of the Moon are developed in the context of a future human lunar exploration programme, such as that proposed by the recently formulated Global Exploration Roadmap.
