The highest SO2 concentration at the source was nearly up to 100 mg/m3. This is an extremely high value, compared to other airborne campaigns and a contamination considered to cause serious illness by the Icelandic Directorate of Health. Volcanic ash consisted of very fine particles, but the concentration was low when compared to other recent eruptions. Measurements of the far plume showed that scavenging is very active.

It is still one of the major problems of air pollution in Germany. The limit values of fine particulate matter PM10 are often exceeded in bigger German cities. Therefore the level of fine particulate matter and other air pollutants are routinely monitored at single hot spots in the cities by measurement stations of the environmental state agencies. However, it is of high interest, what levels of concentrations of fine particulate matter are to be found in those areas, where no measurement stations are placed. Moreover, it is important to know, how strong exceedings of fine particulate matter concentrations can be influenced by meteorological conditions. In this paper fine particulate matter concentrations are measured with a car, which was equipped with measurement systems for fine particulate matter and which was driving through industrial and rural areas of the state North Rhine Westphalia in Germany. By this means it was possible to measure coarse and fine fractions of particulate matter continuously during driving. In this way the horizontal variation of fine particulate matter could be investigated throughout the state. The measurements comprised dust concentrations of the fractions PM10 (coarse), PM2.5 (more fine) and PM1(very fine), which are addressed within the European environmental legislation. Moreover, every second during driving the full size distribution of particles between 250 nm and 32 μm diameter was measured. Therefore it could be investigated, at what places more bigger or more smaller particles were present under specific meteorological conditions. The mobile car measurements were performed as a case study in a situation with a strong meteorological inversion layer. The mobile measurements of the horizontal variation of fine particulate matter in industrial and rural areas are compared with model prediction calculations. Moreover, using backward trajectories a source appointment of the fine particulate matter could be performed.}, subject = {Feinstaub}, language = {en} } @inproceedings{WeberPohlFischeretal.2015, author = {Weber, Konradin and Pohl, Tobias and Fischer, Christian and Lange, Martin and B{\"o}hlke, Christoph}, title = {Determination of a Vertical Profile of Black Carbon by a Combined Application of a Light Research Aircraft and a Quadcopter Unmanned Aerial Vehicle - A Case Study Using an Airborne Ultraportable Micro-Aethalometer for Black Carbon Measurements at a Rural Site in Germany}, series = {Recent Researches in Electrical and Computer Engineering}, volume = {Recent Advances in Electrical Engineering Series 49}, booktitle = {Recent Researches in Electrical and Computer Engineering}, editor = {Valeri, Mladenov}, publisher = {WSEAS}, isbn = {978-1-61804-315-3}, issn = {1790-5117}, pages = {13 -- 18}, year = {2015}, subject = {Messtechnik}, language = {en} } @inproceedings{WeberFischerLangeetal.2015, author = {Weber, Konradin and Fischer, Christian and Lange, Martin and Pohl, Tobias and B{\"o}hlke, Christoph and Wagner, Frank and Mattis, Ina and Flentje, Harald and Sturm, Klaus and Barth, Joachim and Steinkopff, Thomas and Vogel, Andreas}, title = {Aircraft measurements compared with ceilometer measurements during a sahara dust period in Germany}, series = {Geophysical Research Abstracts: EGU General Assembly 2015}, volume = {17}, booktitle = {Geophysical Research Abstracts: EGU General Assembly 2015}, publisher = {Copernicus}, address = {G{\"o}ttingen}, year = {2015}, abstract = {A significant Sahara dust event took place at the beginning of April 2014 over large areas of Germany and Europe. The German Weather Service (DWD) detected and monitored the expansion and propagation of this dust cloud with a ceilometer network of more than 50 ceilometers. Moreover, these ceilometers were also able to track the altitude of the dust cloud at the positions of the ceilometers. Additionally, aircraft measurements over Germany and France were performed with two aircraft by the Duesseldorf University of Applied Sciences. These aircraft were equipped with optical particle counters (OPC) and were able to measure the particle size distribution within the Sahara dust cloud and as a result of this to calculate the particle mass concentration of the dust. The ceilometer measurements and the aircraft measurements complemented each other: whereas the ceilometers gave continuous information about the Sahara dust cloud at the ceilometer positions, the aircraft measurements delivered interpolating results between the ceilometer positions. Moreover, at several ceilometer positions intercomparison flights were performed by spiraling with the aircraft up or down around the ceilometer laser beam. This gave the unique possibility for comparing the remote sensing results of the ceilometers with the in-situ measurements of the aircraft. This study shows that a significant high amount of Saharan dust particles was transported over Germany during a several days long episode. Furthermore, the intercomparison study between the German ceilometer network and aircraft measurements results shows a good agreement. A combination of these techniques could help to detect the vertical and horizontal distribution of the dust cloud and additionally the particle mass concentration.}, subject = {Deutscher Wetterdienst}, language = {en} } @inproceedings{ArnasonEliassonWeberetal.2015, author = {Arnason, Gylfi and Eliasson, Jonas and Weber, Konradin and B{\"o}hlke, Christoph and Palsson, Thorgeir and R{\"o}gnvaldsson, {\´O}lafur and Thorsteinsson, Throstur and Platt, Ulrich and Tirpitz, Lukas and Jones, Roderic L. and Smith, Paul D.}, title = {Results of airborne measurements in the plume near and far from the 2014 Bardarbunga-Holuhraun eruption}, series = {Geophysical Research Abstracts: EGU General Assembly 2015}, volume = {17}, booktitle = {Geophysical Research Abstracts: EGU General Assembly 2015}, publisher = {Copernicus}, address = {G{\"o}ttingen}, year = {2015}, abstract = {The Volcanic Ash Research (VAR) group is focused on airborne measurement of ash contamination to support safe air travel. In relations to the recent eruption, the group measured ash and several gaseous species in the plume 10-300 km from the volcano. The eruption emitted ash turned out to be mostly in the fine aerosol range (much less than 10 micrometers in diameter). Our highest measured concentrations were lower than 1 mg/m3 indicating that commercial air traffic was not threatened (greater than 2 mg/m3) by the ash contamination. But we measured sulfur dioxide (SO2 ) up to 90 mg/m3, which presented a potentially dangerous pollution problem. However, airborne measurements indicate that the sulfur concentration decays (probably due to scavenging) as the plume is carried by the wind from the volcano, which limits the area of immediate danger to the public. Here we present size distribution for particulate matter collected during flights, near and far from the crater at various times. The particle data is then compared with simultaneously collected sulfur dioxide data and the rate of decay of is estimated. Sulfur and particle concentration variations with height in the far plume are presented. Some airborne measurements for H2S, NO, NO2 and CO2 will also be presented.

The eruption started in late August 2014 and is still ongoing as of January 2015. The main threat from this event has been atmospheric pollution of SO2 that is carried by wind to all parts of the country and produces elevated concentrations of SO2 that have frequently violated National Air Quality Standards (NAQS) in many population centers. The Volcanic Ash Research (VAR) group in Iceland is focused on airborne measurement of ash contamination to support safe air travel, as well as various gas concentrations. In relation to the Holuhraun eruption the VAR group has organized an investigation campaign including 10 measurement flights and performed measurements of both the source emissions and the plume distribution. SO2 concentrations measured at the source showed clear potential for creating pollution events in the toxic range and contamination of surface waters. The data obtained in the measurement campaign was used for calibration of the WRF-chem model of the dispersion of SO2 and volcanic ash concentration. The model has both been run in operational forecast mode (since mid October) as well as in a dynamical downscaling mode, to estimate the dispersion and fallout of SO2 from the plume. The model results indicate that a large part of the sulphur was precipitated in the Icelandic highlands. The first melt waters during the spring thaw are likely to contain acid sulphur compounds that can be harmful for vegetation, with the highland vegetation being the most vulnerable. These results will be helpful to estimate the pollution load on farmlands and pastures of farmers.}, subject = {Vulkanismus}, language = {en} } @article{MierMoellenbruckJostetal.2015, author = {Mier, Dominik and M{\"o}llenbruck, Florian and Jost, Michael and Grote, Wolfgang and M{\"o}nnigmann, Martin}, title = {Model predictive control of the steam cycle in a solar power plant}, series = {IFAC-PapersOnLine}, volume = {48}, journal = {IFAC-PapersOnLine}, number = {8}, publisher = {Elsevier}, issn = {2405-8963}, doi = {10.1016/j.ifacol.2015.09.052}, pages = {710 -- 715}, year = {2015}, abstract = {We derive a nonlinear model of the steam cycle of a solar power plant, estimate its unknown parameters with measured data, and design a linear model predictive controller based on the resulting model.

In this paper several examples are demonstrated, how these investigations can be performed by light and microlight propeller aircraft. Throughout the last years innovative aircraft were developed in the light and microlight class showing an excellent flight performance. This enables airborne measurements, which were performed in former years normally by big jet engine driven research aircraft. Moreover, these light and microlight aircraft are equipped with piston motors, which are sturdy enough to operate even in adverse and harsh flight conditions, e.g. in volcanic plumes with high ash concentration. Additionally, turbo charged versions of these airborne piston motors are available, which allow flight altitudes of 7000m - 9000m enabling a large variety of research missions. Another advantage of light and microlight research aircraft is that they are quite cost effective and have a comparatively short certification process for the installation of new measurement equipment. This made it possible to respond fast to the eruption of the Icelandic volcano Eyjafjallaj{\"o}kull 2010 and Grimsv{\"o}tn 2011 with research flights in volcanic ash plumes over Germany and Iceland. In this way it was possible to deliver real airborne measurements additional to the ash plume model calculations of the London Volcanic Ash Advisory Center (VAAC). In this paper examples of airborne measurements in the volcanic plumes of the recent eruptions of Icelandic volcanoes are given.

To address this question, we engineered the protein TipAct, which links growing microtubule ends via end-binding proteins to actin filaments. We show that growing microtubules can be captured and guided by stiff actin bundles, leading to global actin-microtubule alignment. Conversely, growing microtubule ends can transport, stretch and bundle individual actin filaments, thereby globally defining actin filament organization.

Many relevant processes in tropospheric chemistry take place on rather small scales (e.g., tens to hundreds of meters) but often influence areas of several square kilometer. Thus, measurements of the involved trace gases with high spatial resolution are of great scientific interest. In order to identify individual sources and sinks and ultimately to improve chemical transport models, we developed a new airborne instrument, which is based on the well established Differential Optical Absorption Spectroscopy (DOAS) method. The Heidelberg Airborne Imaging DOAS Instrument (HAIDI) is a passive imaging DOAS spectrometer, which is capable of recording horizontal and vertical trace gas distributions with a resolution of better than 100 m. Observable species include NO2, HCHO, C2H2O2, H2O, O3, O4, SO2, IO, OClO and BrO. Here we give a technical description of the instrument including its custom-built spectrographs and CCD detectors. Also first results from measurements with the new instrument are presented. These comprise spatial resolved SO2 and BrO in volcanic plumes, mapped at Mt. Etna (Sicily, Italy), NO2 emissions in the metropolitan area of Indianapolis (Indiana, USA) as well as BrO and NO2 distributions measured during arctic springtime in context of the BRomine, Ozone, and Mercury EXperiment (BROMEX) campaign, which was performed 2012 in Barrow (Alaska, USA).}, language = {en} } @article{EliassonYoshitaniWeberetal.2014, author = {Eliasson, Jonas and Yoshitani, Junichi and Weber, Konradin and Yasuda, Nario and Iguchi, Masato and Vogel, Andreas}, title = {Airborne Measurement in the Ash Plume from Mount Sakurajima: Analysis of Gravitational Effects on Dispersion and Fallout}, series = {International Journal of Atmospheric Sciences}, volume = {2014}, journal = {International Journal of Atmospheric Sciences}, publisher = {Wiley}, issn = {2314-4122}, doi = {10.1155/2014/372135}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-50955}, pages = {16}, year = {2014}, abstract = {Volcanic ash concentrations in the plume from Sakurajima volcano in Japan are observed from airplanes equipped with optical particle counters and GPS tracking devices.

Puffs dispersion is analyzed by the classical diffusion-advection method and a new gravitational dispersion method. The fluid mechanic of the gravitational dispersion, streak fallout, and classical diffusion-advection theory is described in three separate appendices together with methods to find the time gravitational dispersion constant and the diffusion coefficient from satellite photos. The diffusion-advection equation may be used to scale volcanic eruptions so the same eruption plumes can be scaled to constant flux and wind conditions or two eruptions can be scaled to each other. The dispersion analyses show that dispersion of volcanic plumes does not follow either theories completely. It is most likely diffusion in the interface of the plume and the ambient air, together with gravitational flattening of the plumes core. This means larger boundary concentration gradients and smaller diffusion coefficients than state of the art methods can predict.}, subject = {Vulkanismus}, language = {en} } @article{EliassonYasudaWeberetal.2014, author = {Eliasson, Jonas and Yasuda, Nario and Weber, Konradin and Vogel, Andreas and Palsson, Thorgeir}, title = {The role of in-situ measurements of volcanic ash concentrations in preventing economic disasters due to volcanic ash clouds}, series = {Journal of Integrated Disaster Risk Management}, volume = {4}, journal = {Journal of Integrated Disaster Risk Management}, number = {1}, publisher = {Journal of Integrated Disaster Risk Management}, issn = {2185-8322}, doi = {10.5595/idrim.2014.0092}, pages = {48 -- 60}, year = {2014}, language = {en} } @article{JostGroteMoellenbrucketal.2014, author = {Jost, Michael and Grote, Wolfgang and M{\"o}llenbruck, Florian and M{\"o}nnigmann, Martin}, title = {Plant-wide control of a parabolic trough power plant with thermal energy storage}, series = {IFAC Proceedings Volumes}, volume = {47}, journal = {IFAC Proceedings Volumes}, number = {3}, publisher = {Elsevier}, issn = {2589-3653}, doi = {10.3182/20140824-6-ZA-1003.00879}, pages = {419 -- 425}, year = {2014}, abstract = {We present a control scheme for a parabolic trough power plant that is equipped with a molten salt thermal energy storage system.

Onboard instruments included gas detectors (e.g., SO2, CO2), visible \& thermal IR cameras, air samplers, temperature pressure \& humidity sensors, particle counters, \& a nephelometer. Deployments are timed to support bimonthly overflights of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) onboard the NASA Terra satellite (26 deployments to date). In situ observations of dilute plume SO2 concentrations (~1-20ppmv), plume dimensions, and associated temperature, pressure, \& humidity profiles, validate detailed radiative transfer-based SO2 retrievals, as well as archive-wide ASTER band-ratio SO2 algorithms. Our recent UAV-based CO2 observations confirm high concentrations (e.g., ~3000ppmv max at summit jet), with 1000-1500ppmv flank values, and essentially global background CO2 levels (400ppmv) over distal surroundings. Transient Turrialba He detections (up to 20ppmv) were obtained with a small (~10kg) airborne mass spectrometer on a light aircraft—a UAV version (~3kg) will deploy there soon on the UCR DELTA 500. Thus, these platforms, though small (most payloads <500gm), can perform valuable systematic measurements of potential eruption hazards, as well as of volcano processes. Because they are economical, flexible, and effective, such platforms promise unprecedented capabilities for researchers and responders throughout Central and South America, undertaking volcanic data acquisitions uniquely suited to such small aircraft in close proximity to known hazards, or that were previously only available using full-sized manned aircraft.

Hydroxyl radicals (OH) are the most important reagent for the oxidation of trace gases in the atmosphere. OH concentrations measured during recent field campaigns in isoprene-rich environments were unexpectedly large. A number of studies showed that unimolecular reactions of organic peroxy radicals (RO2) formed in the initial reaction step of isoprene with OH play an important role for the OH budget in the atmosphere at low mixing ratios of nitrogen monoxide (NO) of less than 100 pptv. It has also been suggested that similar reactions potentially play an important role for RO2 from other compounds. Here, we investigate the oxidation of methacrolein (MACR), one major oxidation product of isoprene, by OH in experiments in the simulation chamber SAPHIR under controlled atmospheric conditions. The experiments show that measured OH concentrations are approximately 50\% larger than calculated by the Master Chemical Mechanism (MCM) for conditions of the experiments (NO mixing ratio of 90 pptv). The analysis of the OH budget reveals an OH source that is not accounted for in MCM, which is correlated with the production rate of RO2 radicals from MACR. In order to balance the measured OH destruction rate, 0.77 OH radicals (1σ error: ± 0.31) need to be additionally reformed from each reaction of OH with MACR. The strong correlation of the missing OH source with the production of RO2 radicals is consistent with the concept of OH formation from unimolecular isomerization and decomposition reactions of RO2. The comparison of observations with model calculations gives a lower limit of 0.03 s-1 for the reaction rate constant if the OH source is attributed to an isomerization reaction of MACR-1-OH-2-OO and MACR-2-OH-2-OO formed in the MACR + OH reaction as suggested in the literature (Crounse et al., 2012). This fast isomerization reaction would be a competitor to the reaction of this RO2 species with a minimum of 150 pptv NO. The isomerization reaction would be the dominant reaction pathway for this specific RO2 radical in forested regions, where NO mixing ratios are typically much smaller.}, language = {en} } @article{NehrBohnDornetal.2014, author = {Nehr, Sascha and Bohn, Birger and Dorn, Hans-Peter and Fuchs, H. and H{\"a}seler, R. and Hofzumahaus, A. and Li, X. and Rohrer, F. and Tillmann, R. and Wahner, A.}, title = {Atmospheric photochemistry of aromatic hydrocarbons: OH budgets during SAPHIR chamber experiments}, series = {Atmospheric Chemistry and Physics}, volume = {14}, journal = {Atmospheric Chemistry and Physics}, number = {13}, publisher = {Copernicus}, issn = {1680-7324}, doi = {10.5194/acp-14-6941-2014}, pages = {6941 -- 6952}, year = {2014}, abstract = {Abstract. Current photochemical models developed to simulate the atmospheric degradation of aromatic hydrocarbons tend to underestimate OH radical concentrations. In order to analyse OH budgets, we performed experiments with benzene, toluene, p-xylene and 1,3,5-trimethylbenzene in the atmosphere simulation chamber SAPHIR. Experiments were conducted under low-NO conditions (typically 0.1-0.2 ppb) and high-NO conditions (typically 7-8 ppb), and starting concentrations of 6-250 ppb of aromatics, dependent on OH rate constants. For the OH budget analysis a steady-state approach was applied in which OH production and destruction rates (POH and DOH) have to be equal. The POH were determined from measurements of HO2, NO, HONO, and O3 concentrations, considering OH formation by photolysis and recycling from HO2. The DOH were calculated from measurements of the OH concentrations and total OH reactivities. The OH budgets were determined from DOH/POH ratios. The accuracy and reproducibility of the approach were assessed in several experiments using CO as a reference compound where an average ratio DOH/POH = 1.13 ± 0.19 was obtained. In experiments with aromatics, these ratios ranged within 1.1-1.6 under low-NO conditions and 0.9-1.2 under high-NO conditions. The results indicate that OH budgets during photo-oxidation experiments with aromatics are balanced within experimental accuracies. Inclusion of a further, recently proposed OH production via HO2 + RO2 reactions led to improvements under low-NO conditions but the differences were small and insignificant within the experimental errors.}, language = {en} } @inproceedings{NehrTanabe2014, author = {Nehr, Sascha and Tanabe, Shin-ichi}, title = {ISO/TC 146/SC 6 - Setting international standards for the assessment of indoor air quality}, series = {Indoor Air 2014 - 13th International Conference on Indoor Air Quality and Climate, Hong Kong}, booktitle = {Indoor Air 2014 - 13th International Conference on Indoor Air Quality and Climate, Hong Kong}, address = {Hong Kong}, year = {2014}, language = {en} } @article{NorisMusallSalometal.2014, author = {Noris, Federico and Musall, Eike and Salom, Jaume and Berggren, Bj{\"o}rn and Jensen, S{\o}ren {\O}stergaard and Lindberg, Karen and Sartori, Igor}, title = {Implications of weighting factors on technology preference in net zero energy buildings}, series = {Energy and Buildings}, volume = {82}, journal = {Energy and Buildings}, publisher = {Elsevier}, doi = {10.1016/j.enbuild.2014.07.004}, pages = {250 -- 262}, year = {2014}, abstract = {With the current movement towards Net Zero Energy Buildings (Net ZEBs) decisions regarding energy carrier weighting factors will have implications on which technologies could be favoured or disfavoured, and therefore adopted or not adopted, in the building sector of the near future. These implications should be taken into consideration by policy makers when developing legislation and regulations addressing the building sector. A parametric analysis was conducted on six buildings in Europe of different typologies and climates in order to assess how different weighting factors would impact the choice of technical systems to be installed. For each combination the amount of PV capacity necessary to achieve a net zero balance has been calculated and used as the main indicator for comparison; where less PV area means more favourable condition. The effect of including a solar thermal system is also discussed. With the current European national weighting factors, biomass boiler is largely the preferred solution, frequently achieving the balance with PV installed on the roof, while gas boiler is the most penalized. The situation changes when strategic weighting factors are applied. Lower weighting factors for electricity and district heating, e.g. reflecting national targets of increased penetration of renewables in such grids, would promote the use of heat pump and district heating, respectively. Asymmetric factors aimed at rewarding electricity export to the grid would facilitate the achievement of the zero balance for all technologies, promoting cogeneration in some cases. On the contrary, low weighting factors for electricity, e.g. reflecting a scenario of high decarbonisation of the power system, prove quite demanding; only few technical solutions would be able to reach the balance within the available roof area for PV, because of the low value credited to exported electricity. In this situation, the preferred solution would be heat pumps combined with solar thermal. In addition, the choice of weighting factors and the resulting favoured technologies will determine the temporal matching of load and generation. While all-electric solutions tend to use the grid as seasonal storage, other solutions will have a yearly net export of electricity to the grid to compensate for the supply of other (thermal) energy carriers. Therefore, it is important to consider the implications for the electricity grid resulting from the choice of weighting factors.}, language = {en} } @techreport{SalomMarszalCandanedoetal.2014, author = {Salom, Jaume and Marszal, Anna Joanna and Candanedo, Jos{\´e} A. and Widen, Joakim and Byskov Lindberg, Karen and Sartori, Igor}, title = {Analysis of Load Match and Grid Interaction Indicators in Net Zero Energy Buildings with High-Resolution Data: A report of Subtask A IEA Task 40/Annex 52 Towards Net Zero Energy Solar Buildings}, publisher = {Catalonia Institute for Energy Research, IREC}, address = {Barcelona}, organization = {Catalonia Institute for Energy Research, IREC}, url = {http://nbn-resolving.de/https://www.researchgate.net/publication/271135453_Analysis_of_load_match_and_grid_interaction_indicators_in_net_zero_energy_buildings_with_high-resolution_data}, year = {2014}, language = {en} } @article{MusallVoss2014, author = {Musall, Eike and Voss, Karsten}, title = {Renewable Energy Ratio in Net Zero Energy Buildings}, series = {REHVA Journal}, volume = {51}, journal = {REHVA Journal}, number = {3}, publisher = {REHVA}, pages = {14 -- 18}, year = {2014}, language = {en} } @article{GaidaWeinbergJahr2014, author = {Gaida, Philipp and Weinberg, Kerstin and Jahr, Andreas}, title = {Viscoelastic modelling and experimental results of a dielectric electro-active polymer diaphragm actuator}, series = {Proceedings in Applied Mathematics and Mechanics (PAMM)}, volume = {14}, journal = {Proceedings in Applied Mathematics and Mechanics (PAMM)}, number = {1}, edition = {85th Annual Meeting of the GAMM.

During the entire harvesting, every stalk is cut at least one time. For other agricultural processes, such as grain crop harvesting or mulching of brownfields, cutting processes belong also to the main techniques. They have a significant influence on the efficiency and profitability of agricultural machines. Minimizing wear has a high level of importance regarding an environmental friendly and resource efficient agriculture. Wear during agricultural cutting processes is mainly caused due to abrasion and impact stress. Blunt and deformed blades affect the energy efficiency and the cutting quality. The increase of fuel consumption and frequent machine breakdowns with an involvement of high labor and material costs generate considerable economic losses. A consequent, methodical optimization of the wear behavior of the blades can offer a high saving potential of ecological and economic resources. The blade geometry, base material and heat respectively surface treatment substantially determine the wear resistance. Under technological and economic considerations these parameters have to be optimized. Therefore, a test method has been developed at the FMDauto in cooperation with the Ennepetaler Schneid- und M{\"a}htechnik (ESM) GmbH \& Co KG. The test bench enables to test different blades of agricultural machines under standardized and repeatable conditions. This paper presents the test bench and the results of several wear tests. The examinations of the abrasive wear and the impact stress on cutter blades are shown. Algorithms developed at FMDauto are used to analyze the results. It is carried out that further developments of the analyzing methods to describe the sharpness and disruptions of cutter blades are reasonable.}, language = {en} } @incollection{LohmannIlleAdam2013, author = {Lohmann, Sandra and Ille, Fabian and Adam, Mario}, title = {Solar cooling in a hardware-in-the-loop test and pilot plant.

Therefore the influence of "reality factors" on the sound evaluation of household appliances was investigated within the framework of nine experiments. These tests were performed in four different settings with varied reality degrees. The psychological realism and the perceived face validity of the tests were examined by means of interviews. The results reveal, on the one hand, that stimuli are perceived as more pleasant in everyday-like environments. The analysis of the relative judgments shows, on the other hand, that the influence of the experimental realism is moderated by a number of factors. These are the saliency and meaning of the sounds, differences between the assessed devices, and personality traits. The correlation and regression analysis confirms that the perceived sound character is widely independent from experimental realism.

The insertion of Ala-Pro between MFα prepro sequence and protein of interest leads to an improved processing of the signal sequence in case of interleukin-6 (IL-6) and interferon-α 2a (IFNα-2a). Modeling of the transition sequences confirmed a better exposition of the Kex2p-cleavage site in dependency of Ala-Pro insertions. Analysis of the secreted proteins revealed activity of an Ala-Pro specific endoprotease. Partial removal of the N-terminal Ala-Pro dipeptide was also detected during IFNα-2a processing. The putative protease responsible for the processing of Ala-Pro dipeptides was identified by gene deletion. Significant similarities with Saccharomyces cerevisiae Ste13p were identified.

The recombinantly strongly expressed cytosolic ferritin heavy chain (FTH1) was analyzed with regard to its potential as fusion partner for difficult-to-express target proteins. A fragment of the parathyroid hormone (PTH) was chosen to explore whether fusion to FTH1 enhances PTH stability. We could show that the expression level of this fusion protein was at least of the magnitude of that of FTH1 without fusion partner. The solubility of the fusion protein was increased in comparison to FTH1 alone and no degradation of PTH occurred when fused C-terminally to FTH1.

Still commercial studios cannot have full interaction between actors and virtual scene because actors data are not completely digital available as well as the feedback for actors is still not sufficient. Markerless full body tracking might revolutionize virtual studio technology as it allows better interaction between real and virtual world. This article reports about using a markerless actor tracking in a virtual studio with a tracking volume of nearly 40 cubic meter enabling up to three actors within the green box. The tracking is used for resolving the occlusion between virtual objects and actors so that the Tenderer can output automatically a mask for virtual objects in the foreground in case the actor is behind. It is also used for triggering functions scripted within the Tenderer engine, which are attached to virtual objects, starting any kind of action (e.g., animation). Last but not least the system is used for controlling avatars within the virtual set. All tracking and rendering is done within a studio frame rate of 50 Hz with about 3 frames delay. The markerless actor tracking within virtual studios is evaluated by experts using an interview approach. The statistical evaluation is based on a questionnaire.}, language = {en} } @inproceedings{BurgaDaemenDjuderijaetal.2013, author = {Burga, Jose and Daemen, Jeff and Djuderija, Sascha and Gnehr, Maren and Goossens, Lars and Hartz, Sven and Haufs-Brusberg, Peter and Herder, Jens and Ibrahim, Mohammed and Koop, Nikolas and Leske, Christophe and Meyer, Laurid and M{\"u}ller, Antje and Salgert, Bj{\"o}rn and Schroeder, Richard and Thiele, Simon}, title = {Four Metamorphosis States in a Distributed Virtual (TV) Studio: Human, Cyborg, Avatar, and Bot}, series = {10th International Conference on Visual Media Production (CVMP 2013), London}, booktitle = {10th International Conference on Visual Media Production (CVMP 2013), London}, address = {London}, year = {2013}, abstract = {The major challenge in virtual studio technology is the interaction between the actor and virtual objects.

This randomized controlled study examined the efficacy of a telephone-assisted parent-administered behavioural intervention (bibliotherapy) in families with preschool children with externalizing problem behaviour. Families were randomly assigned to a treatment group (n = 26) and an untreated waitlist control group (n = 22). The intervention comprised the reading of an 11 chapter self-help book and 11 weekly telephone consultations. Compared to the control group, the treatment group demonstrated significant decreases in parent-reported externalizing and internalizing child problem behaviour and dysfunctional parenting practices. Moreover, treated parents reported less parenting-related strains and decreases in parental depression, anxiety, and stress. The results suggest that telephone-assisted self-administered parent training is an effective alternative to more intensive forms of behavioural family intervention for preschool children with externalizing problem behaviour.}, language = {en} } @article{WolfGaidaStuhlsatzetal.2013, author = {Wolf, Christian and Gaida, Daniel and Stuhlsatz, Andr{\´e} and Ludwig, Thomas and McLoone, Se{\´a}n and Bongards, Michael}, title = {Predicting organic acid concentration from UV/vis spectrometry measurements - a comparison of machine learning techniques}, series = {Transactions of the Institute of Measurement and Control}, volume = {35}, journal = {Transactions of the Institute of Measurement and Control}, number = {1}, publisher = {sage journals}, doi = {10.1177/0142331211403797}, pages = {5 -- 15}, year = {2013}, language = {en} } @article{FuchsHofzumahausRohreretal.2013, author = {Fuchs, H. and Hofzumahaus, A. and Rohrer, F. and Bohn, Birger and Brauers, Theo and Dorn, Hans-Peter and H{\"a}seler, R. and Holland, F. and Kaminski, M. and Li, X. and Lu, K. and Nehr, Sascha and Tillmann, R. and Wegener, R. and Wahner, A.}, title = {Experimental evidence for efficient hydroxyl radical regeneration in isoprene oxidation}, series = {Nature Geoscience}, volume = {6}, journal = {Nature Geoscience}, number = {12}, publisher = {Springer Nature}, issn = {1752-0894}, doi = {10.1038/NGEO1964}, pages = {1023 -- 1026}, year = {2013}, language = {en} }
