AbstractThe origin of short timescale (weeks/months) variability of AGN, whether due to intrinsic disc variations or reprocessing of X‐ray emission by a surrounding accretion disc, has been a puzzle for many years. However recently a number of observational programmes, particularly of NGC 5548 with Swift, have shown that the UV/optical variations lag behind the X‐ray variations in a manner strongly supportive of X‐ray reprocessing. Somewhat surprisingly, the implied size of the accretion disc is ∼3 times greater than expected from a standard, smooth, Shakura‐Sunyaev thin disc model. Although the difference may be explained by a clumpy accretion disc, it is not clear whether the difference will occur in all AGN or whether it may change as, eg, a function of black hole mass, accretion rate, or disc temperature. Measurements of interband lags for most AGN require long timescale monitoring, which is hard to arrange. However for low mass (<106 M⊙) AGN, the combination of XMM‐Newton EPIC (X‐rays) with the optical monitor in fast readout mode allows an X‐ray/UV‐optical lag to be measured within a single long observation. Here we summarise previous related observations and report on XMM‐Newton observations of NGC 4395 (mass 100 times lower, accretion rate ∼20 times lower than for NGC 5548). We find that the UVW1 lags the X‐rays by ∼470 s. Simultaneous observations at 6 different ground based observatories also allowed the g‐band lag (∼800 s) to be measured. These observations are in agreement with X‐ray reprocessing but initial analysis suggests that, for NGC 4395, they do not differ markedly from the predictions of the standard thin disc model.

Testing propagating mass accretion rate fluctuations model PROPFLUC on black hole X‐ray binaries
Authors: Rapisarda S. , Ingram A. , van der Klis M. 
Published: May 2016

AbstractOver the past 20 years, a consistent phenomenology has been established to describe the variability properties of black hole X‐ray binaries. However, the physics behind the observational data is still poorly understood. The recently proposed model PROPFLUC assumes a truncated disc/hot inner flow geometry, with mass accretion rate fluctuations propagating through a precessing inner flow. These two processes give rise respectively to broad band variability and a quasi‐periodic oscillation (QPO) on the precession frequency. We recently applied systematically for the first time PROPFLUC on a black hole candidate (MAXI J1543‐564) in order to compare the results of phenomenological and physical modeling of the source power spectrum and to give a physical interpretation of the rising phase of the source outburst. Here we resume the results of our study on MAXI J1543‐564 and we discuss future PROPFLUC implementations. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Eclipsing the innermost accretion disc regions in AGN
Authors: Sanfrutos M , Miniutti G. , Dovčiak M. , Agís–González B. 
Published: May 2016

AbstractVariable X‐ray absorption has been observed in active galactic nuclei (AGN) on several time scales. Observations allow us to identify the absorber with clouds associated either with the clumpy torus (parsec scales, long timescales) or with the broad line region (BLR) (short timescales). In the latter, the cloud size has been estimated to be of the order of few gravitational radii from the observed absorption variability. Such small cloud sizes are comparable to the X‐ray emitting regions so that a detailed modeling of occultation events in AGN has the potential of enabling us to infer accurately the geometry of the system. We have developed a relativistic X‐ray spectral model for occultation events and we present here theoretical predictions on the different observables that can be inferred by studying X‐ray eclipses in simulated XMMNewton data. These include the size of the X‐ray emitting regions as well as more fundamental parameters such as the black hole spin and the system inclination. We find that absorption varies as a function of the energy range and that its maximum takes place when the approaching part of the accretion disc is covered. Therefore we study the hard‐to‐soft (H/ S) ratio light curves produced during an eclipse and use them to characterise the properties of the inner accretion disc in a new model‐independent way.

Interactive educational software for teaching water distribution networks design
Authors: Zhang Hui , Xu Jin‐Lan , Cheng Xin 
Published: May 2016

ABSTRACTThis paper presents an educational software focused on teaching the design process of water distribution networks to Municipal Engineering students and Environmental Engineering students. This software has been developed using Delphi 7.0. And it is divided into four sections: (1) interactive drawing tools for developing the topology model of a water distribution network, (2) effective management of different kinds of data related to water distribution networks, (3) hydraulic analysis for designing a water distribution system in operational conditions when varying the parameter values, and (4) AutoCAD interface files produced to help students draw the design scheme. This software has become a very useful tool for undergraduate students in compliment to the theoretical classes or alone, as a self‐study tool. © 2016 Wiley Periodicals, Inc.

Design and monitoring of a micro‐cogeneration system: A wide practice proposed for engineering education
Authors: Crespo Bárbara , Rey Guillermo , Míguez Carla , Míguez José Luis , Cuevas Alonso Miguel 
Published: May 2016

ABSTRACTLearning by doing is essential in engineering education, along with topics such as systems automation and control and energy efficiency. This article presents work including all of these different topics. A micro‐cogeneration facility located at the University of Vigo is studied. The experimental plant is automated after detecting the most important variables and actuations. A system responsible for the control, supervision, and monitoring of the system was developed using the programming software LabVIEW. All of these processes are explained in depth here. Finally, a complete practice experience is proposed for the next course of the Master of Thermal Engineering programme taught at the University of Vigo. Different tasks are included: the study of the operating principle of a micro‐cogeneration system, the analysis of measurement devices and actuators for the automation of an experimental facility, LabVIEW programming, and interaction with the integrated system. The effectiveness of the proposed methodology will be evaluated through a five‐point Likert‐type scale survey. © 2016 Wiley Periodicals, Inc.

AbstractBis[2,4‐di(trifluoromethyl)quinoline‐7‐yl]amine (1), bis[2,4‐di(trifluoromethyl)quinoline‐7‐yl]methylamine (2), bis[2,4‐di(trifluoromethyl)quinoline‐7‐yl]phenylamine derivatives, Q2NPhX; X=NO2 (3 a), I (3 b), H (3 c), OMe (3 d), and NH2 (3 e), tris[2,4‐di(trifluoromethyl)quinoline‐7‐yl]amine (4), and bis[2,4‐di(pentafluoroethyl)quinoline‐7‐yl]‐4‐nitrophenylamine (5) were prepared as functional fluorophores. On irradiating the solution samples, 1 showed no noticeable alteration, whereas 2, 3 a–d, and 4 showed emission color changes from yellowish green to blue, indicating that a photoreaction took place. Analyses of the photoproduct based on absorption and emission spectra, 1H NMR spectra, and X‐ray crystallography indicated that photocyclization reactions occurred regioselectively and quantitatively to form bent–bent dipyridocarbazoles. In 3 a–d, the reaction rates depended on the solvent polarity and the substituent on the benzene ring. The photoreactions were accelerated with decreasing solvent polarity and with increasing electron‐withdrawing character of the substituents. The photocyclization of triquinolineamine 4 was faster than that of 3 a in all solvents. The results of semiempirical quantum‐chemical PM6 calculations suggested that the observed regioselective photocyclization could be explained by stabilization of the excited triplet transition state for the bent–bent form because of the molecular geometry with the CH−NQ hydrogen bonds. The solution of 5 in MeOH displayed photoreaction‐induced self‐assembly behavior to form twisted tape‐like fibers of width 200 nm, as determined by TEM imaging.
