Urban air quality and human health are among the key aspects of future urban planning. In order to address pollutants such as ozone and particulate matter, efforts need to be made to quantify and reduce their concentrations. One important aspect in understanding urban air quality is the influence of urban vegetation which may act as both emitter and sink for trace gases and aerosol particles. In this context, the "Berlin Air quality and Ecosystem Research: Local and long-range Impact of anthropogenic and Natural hydrocarbons 2014" (BAERLIN2014) campaign was conducted between 2 June and 29 August in the metropolitan area of Berlin and Brandenburg, Germany. The predominant goals of the campaign were (1) the characterization of urban gaseous and particulate pollution and its attribution to anthropogenic and natural sources in the region of interest, especially considering the connection between biogenic volatile organic compounds and particulates and ozone; (2) the quantification of the impact of urban vegetation on organic trace gas levels and the presence of oxidants such as ozone; and (3) to explain the local heterogeneity of pollutants by defining the distribution of sources and sinks relevant for the interpretation of model simulations. In order to do so, the campaign included stationary measurements at urban background station and mobile observations carried out from bicycle, van and airborne platforms. This paper provides an overview of the mobile measurements (Mobile BAERLIN2014) and general conclusions drawn from the analysis. Bicycle measurements showed micro-scale variations of temperature and particulate matter, displaying a substantial reduction of mean temperatures and particulate levels in the proximity of vegetated areas compared to typical urban residential area (background) measurements. Van measurements extended the area covered by bicycle observations and included continuous measurements of O3, NOx, CO, CO2 and point-wise measurement of volatile organic compounds (VOCs) at representative sites for traffic- and vegetation-affected sites. The quantification displayed notable horizontal heterogeneity of the short-lived gases and particle number concentrations. For example, baseline concentrations of the traffic-related chemical species CO and NO varied on average by up to ±22.2 and ±63.5 \%, respectively, on the scale of 100 m around any measurement location. Airborne observations revealed the dominant source of elevated urban particulate number and mass concentrations being local, i.e., not being caused by long-range transport. Surface-based observations related these two parameters predominantly to traffic sources. Vegetated areas lowered the pollutant concentrations substantially with ozone being reduced most by coniferous forests, which is most likely caused by their reactive biogenic VOC emissions. With respect to the overall potential to reduce air pollutant levels, forests were found to result in the largest decrease, followed by parks and facilities for sports and leisure. Surface temperature was generally 0.6-2.1 °C lower in vegetated regions, which in turn will have an impact on tropospheric chemical processes. Based on our findings, effective future mitigation activities to provide a more sustainable and healthier urban environment should focus predominantly on reducing fossil-fuel emissions from traffic as well as on increasing vegetated areas.}, language = {en} } @article{FuHeeminkLuetal.2016, author = {Fu, Guangliang and Heemink, Arnold and Lu, Sha and Segers, Arjo and Weber, Konradin and Lin, Hai-Xiang}, title = {Model-based aviation advice on distal volcanic ash clouds byassimilating aircraft in situ measurements}, series = {Atmospheric Chemistry and Physics}, volume = {16}, journal = {Atmospheric Chemistry and Physics}, number = {14}, publisher = {Copernicus}, issn = {1680-7324}, doi = {10.5194/acp-16-9189-2016}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-50058}, pages = {9189 -- 9200}, year = {2016}, abstract = {Abstract. The forecast accuracy of distal volcanic ash clouds is important for providing valid aviation advice during volcanic ash eruption. However, because the distal part of volcanic ash plume is far from the volcano, the influence of eruption information on this part becomes rather indirect and uncertain, resulting in inaccurate volcanic ash forecasts in these distal areas. In our approach, we use real-life aircraft in situ observations, measured in the northwestern part of Germany during the 2010 Eyjafjallaj{\"o}kull eruption, in an ensemble-based data assimilation system combined with a volcanic ash transport model to investigate the potential improvement on the forecast accuracy with regard to the distal volcanic ash plume. We show that the error of the analyzed volcanic ash state can be significantly reduced through assimilating real-life in situ measurements. After a continuous assimilation, it is shown that the aviation advice for Germany, the Netherlands and Luxembourg can be significantly improved. We suggest that with suitable aircrafts measuring once per day across the distal volcanic ash plume, the description and prediction of volcanic ash clouds in these areas can be greatly improved.}, language = {en} } @inproceedings{ComeronJackKassianovetal.2016, author = {Comeron, Adolfo and Jack, James and Kassianov, Evgueni I. and Sch{\"a}fer, Kiaus and Picard, Richard H and Weber, Konradin}, title = {Remote Sensing of Clouds and the Atmosphere XXI Introduction}, series = {Remote Sensing of Clouds and the Atmosphere XXI : 28-29 September 2016, Edinburgh, United Kingdom}, booktitle = {Remote Sensing of Clouds and the Atmosphere XXI : 28-29 September 2016, Edinburgh, United Kingdom}, publisher = {SPIE}, address = {Bellingham, Washington, USA}, isbn = {978-1-5106-0406-3}, year = {2016}, language = {en} } @article{EliassonYoshitaniMikietal.2016, author = {El{\´i}asson, Jonas and Yoshitani, Junichi and Miki, Daisuke and Weber, Konradin and B{\"o}lke, Christoph and Scharifi, Emad}, title = {Measurements of Particle Distribution and Ash Fluxes in the Plume of Sakurajima Volcano with Optical Particle Counter}, series = {Journal of Disaster Research}, volume = {11}, journal = {Journal of Disaster Research}, number = {1}, publisher = {Fuji Technology Press Ltd.}, issn = {1883-8030}, doi = {10.20965/jdr.2016.p0085}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-50030}, pages = {85 -- 95}, year = {2016}, abstract = {Volcanic eruptions have caused very costly disturbances of international air traffic. This problem has been dealt with by simulating the formation and migration of dangerous ash plumes. However, the results of the simulations have sometimes been too safe, producing ash clouds that are too large. This was especially the case for the North Atlantic in 2010 (Eyjafjallaj{\"o}kull) and 2011 (Gr{\´i}msv{\"o}tn). Since 2012, an international cooperation team led by the Disaster Prevention Research Institute (DPRI) of Kyoto University has conducted airborne measurements of volcanic ash concentrations in the plume from Mount Sakurajima in Kagoshima Prefecture, Japan. This volcano was chosen because of its frequent but limited eruptions, which allow close observation. These measurement campaigns have provided data showing gravitational flattening of the plume, a new and previously unknown dispersion process of volcanic plumes. A new and previously unknown fallout process, called streak fallout, also has been measured. Results concerning plume flux, concentration distributions, aerosol (PM10) content of the plume, and content of very fine particles (PM2.5 and PM1) are presented, and the ways by which the observational methods can be used to produce reliable initial data and boundary values for simulations of plume dispersion are discussed.}, language = {en} } @article{EliassonWeberVogeletal.2016, author = {El{\´i}asson, Jonas and Weber, Konradin and Vogel, Andreas and P{\´a}lsson, Thorgeir and Yoshitani, Junichi and Miki, Daisuke}, title = {Investigation and Separation of Turbulent Fluctuations in Airborne Measurements of Volcanic Ash with Optical Particle Counters}, series = {Journal of Disaster Research}, volume = {11}, journal = {Journal of Disaster Research}, number = {1}, publisher = {Fuji Technology Press Ltd.}, issn = {1883-8030}, doi = {10.20965/jdr.2016.p0072}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-50023}, pages = {72 -- 84}, year = {2016}, abstract = {The science of measuring airborne volcanic ash concentrations supports research in such fields as atmospheric environmental science and the modeling of atmospheric pollution from volcanoes, and is thus very valuable to the aviation industry. These measurements show large scatter directly traceable to turbulent fluctuations responsible for diffusing volcanic dust. Before semistationary components in observations can be compared to each other or to simulation results, they must be separated from fluctuations. In the design of the separation process, however, neither seasonal or diurnal periodicity nor random disturbance with known properties exists to serve as a guideline. It has been suggested that fluctuations could be eliminated through repeated convolutions of a simple 3-point filter enough times. The number of convolutions is chosen from the change in the rate of increase of a special variability parameter. When semistationary concentrations are separated from fluctuations, their statistics are compared to turbulence parameters and the autocorrelation of the series. The method is demonstrated using three measurement series from Sakurajima, Japan measured in 2013. It is concluded that this new method is simple and trustworthy where knowledge and experience of the environmental parameters can be utilized to support the results. They indicate a variability of 40\% in the relative fluctuations of the PM10 and around 20\% of the PM2.5. The relative fluctuations may be considered completely random, but normally distributed rather than a white noise with an evenly distributed variance spectrum.}, language = {en} } @article{NehrGlatkeHellacketal.2016, author = {Nehr, Sascha and Glatke, D. and Hellack, Bryan and Herrmann, Hartmut and Hoffmann, B. and Kuhlbusch, T.

To quantify the influence we developed a probabilistic framework based on polynomial chaos (PC) that propagates stochastic input variables through any computational model. We considered a stochastic E-ρ relationship and a stochastic hip contact force, representing realistic variability of experimental data. Their influence on the prediction of principal strains (ϵ1 and ϵ3) was quantified for one human proximal femur, including sensitivity and reliability analysis. Large variabilities in the principal strain predictions were found in the cortical shell of the femoral neck, with coefficients of variation of ≈40\%. Between 60 and 80\% of the variance in ϵ1 and ϵ3 are attributable to the uncertainty in the E-ρ relationship, while ≈10\% are caused by the load magnitude and 5-30\% by the load direction. Principal strain directions were unaffected by material and loading uncertainties.

Currently, there are no means available to detect ash in flight as the particles are too fine (radii < 30 μm) for on-board radar detection and, even in good visibility, ash clouds are difficult or impossible to detect by eye. The economic cost and societal impact of the April/May 2010 Icelandic eruption of Eyjafjallaj{\"o}kull generated renewed interest in finding ways to identify airborne volcanic ash in order to keep airspace open and avoid aircraft groundings. We have designed and built a bi-spectral, fast-sampling, uncooled infrared camera device (AVOID) to examine its ability to detect volcanic ash from commercial jet aircraft at distances of more than 50 km ahead. Here we report results of an experiment conducted over the Atlantic Ocean, off the coast of France, confirming the ability of the device to detect and quantify volcanic ash in an artificial ash cloud created by dispersal of volcanic ash from a second aircraft. A third aircraft was used to measure the ash in situ using optical particle counters. The cloud was composed of very fine ash (mean radii ~10 μm) collected from Iceland immediately after the Eyjafjallaj{\"o}kull eruption and had a vertical thickness of ~200 m, a width of ~2 km and length of between 2 and 12 km. Concentrations of ~200 μg m(-3) were identified by AVOID at distances from ~20 km to ~70 km. For the first time, airborne remote detection of volcanic ash has been successfully demonstrated from a long-range flight test aircraft.}, language = {en} } @techreport{NeefLaux2016, author = {Neef, Matthias and Laux, Christoph}, title = {Optimierung des elektrischen Nutzungsgrades eines Blockheizkraftwerks durch Abw{\"a}rmeverwertung in einem nachgeschalteten Dampfkraftprozess}, address = {D{\"u}sseldorf}, organization = {Hochschule D{\"u}sseldorf}, doi = {10.2314/GBV:867675985}, year = {2016}, abstract = {Abschlussbericht F{\"o}rderung: Bundesministerium f{\"u}r Bildung und Forschung (BMBF) F{\"o}rderkennzeichen: 03FH006I2 Projektzeitraum: 31.08.2012 -31.08.2015}, language = {de} } @article{WolterZekornNeef2016, author = {Wolter, Nina and Zekorn, Thomas and Neef, Matthias}, title = {Station{\"a}re thermodynamische Prozesssimulationen am Beispiel eines Industriekraftwerks}, series = {BWK: das Energie-Fachmagazin}, volume = {68}, journal = {BWK: das Energie-Fachmagazin}, number = {6}, pages = {6 -- 10}, year = {2016}, abstract = {Um bauliche Ver{\"a}nderungen in bestehenden Kraftwerksprozessen auf ihre Wirkungsweise untersuchen und thermodynamisch beziehungsweise wirtschaftlich bewerten zu k{\"o}nnen, werden thermische Kraftwerksprozesse mit geeigneter Simulationssoftware abgebildet und in verschiedenen Detaillierungsstufen ausgelegt oder nachgerechnet.

Due to the wide range of organic working fluids available the fluid selection adds an additional degree-of-freedom to the early design phase of an ORC process. Despite thermodynamic aspects such as the temperature level of the heat source, other technical, economic, and safety aspects have to be considered. For the fluid selection process in this paper, 22 criteria were identified in six main categories while distinguishing between elimination (EC) and tolerance criteria (TC). For an ORC design, the suggested method follows a practical engineering approach and can be used as a structured way to limit the number of interesting working fluids before starting a detailed performance analysis of the most promising candidates. For the first time, the selection process is applied to a two-stage reference cycle, which uses the waste heat of a large reciprocating engine for cogeneration power plants. It consists of a high temperature (HT) and a low temperature (LT) cycle in which the condensation heat of the HT cycle provides the heat input of the LT cycle. After the fluid selection process, the detailed thermodynamic cycle design is carried out with a thermodynamic design tool that also includes a database for organic working fluids. The investigated ORC cycle shows a net thermal efficiency of about 17.4\% in the HT cycle with toluene as the working fluid and 6.2\% in LT cycle with isobutane as the working fluid. The electric efficiency of the cogeneration plant increases from 40.4\% to 46.97\% with the both stages of the two-stage ORC in operation.}, language = {en} } @incollection{DeckertScherer2016, author = {Deckert, Carsten and Scherer, Anke}, title = {Dao der Innovation: Spannungsfelder der Kreativit{\"a}t in Unternehmen}, series = {Jahrbuch der Kreativit{\"a}t 2014}, booktitle = {Jahrbuch der Kreativit{\"a}t 2014}, editor = {Preiß, J{\"u}rgen}, publisher = {Books on Demand}, address = {Norderstedt}, isbn = {978-3-7392-0194-8}, pages = {101 -- 118}, year = {2016}, abstract = {In dem Beitrag beschreiben die Autoren einige der Widerspr{\"u}che und Paradoxien im Zusammenhang mit Kreativit{\"a}t und schlagen die Nutzung des Wertequadrats nach Helwig zu deren Beschreibung vor.
