Increased competition, short innovation cycles, changed usage patterns, increased customer expectations and cost reduction are the main drivers. Our objective is to analyze to what extend transformation projects have improved the orientation towards the end-customers. Therefore, we selected 38 real-life case studies that are dealing with customer orientation. Our analysis is based on a telecommunication-specific framework that aligns strategy, business processes and information systems. The result of our analysis shows the following: transformation projects that aim to improve the customer orientation are combined with clear goals on costs and revenue of the enterprise. These projects are usually directly linked to the customer touch points, but also to the development and provisioning of products. Furthermore, the analysis shows that customer orientation is not the sole trigger for transformation. There is no one-fits-all solution; rather, improved customer orientation needs aligned changes of business processes as well as information systems related to different parts of the company.}, language = {en} } @inproceedings{DachwaldXuFeldmannetal.2011, author = {Dachwald, Bernd and Xu, Changsheng and Feldmann, Marco and Plescher, Engelbert}, title = {IceMole : Development of a novel subsurface ice probe and testing of the first prototype on the Morteratsch Glacier}, series = {EGU General Assembly 2011 Vienna | Austria | 03 - 08 April 2011}, booktitle = {EGU General Assembly 2011 Vienna | Austria | 03 - 08 April 2011}, year = {2011}, abstract = {We present the novel concept of a combined drilling and melting probe for subsurface ice research.

Considering distances of 200 AU for a new mission, one needs a spacecraft travelling at a speed of close to 10 AU/yr in order to keep the mission duration in the range of less than 25 yrs, a transfer time postulated by ESA.Two propulsion options for the mission have been proposed and discussed so far: the solar sail propulsion and the ballistic/radioisotope electric propulsion. As a further alternative, we here investigate a combination of solar-electric propulsion and radioisotope-electric propulsion. The solar-electric propulsion stage consists of six 22 cm diameter "RIT-22"ion thrusters working with a high specific impulse of 7377 s corresponding to a positive grid voltage of 5 kV. Solar power of 53 kW BOM is provided by a light-weight solar array. The REP-stage consists of four space-proven 10 cm diameter "RIT-10" ion thrusters that will be operating one after the other for 9 yrs in total. Four advanced radioisotope generators provide 648 W at BOM. The scientific instrument package is oriented at earlier studies. For its mass and electric power requirement 35 kg and 35 W are assessed, respectively. Optimized trajectory calculations, treated in a separate contribution, are based on our "InTrance" method.The program yields a burn out of the REP stage in a distance of 79.6 AU for a usage of 154 kg of Xe propellant. With a C3 = 45,1 (km/s)2 a heliocentric probe velocity of 10 AU/yr is reached at this distance, provided a close Jupiter gravity assist adds a velocity increment of 2.7 AU/yr. A transfer time of 23.8 yrs results for this scenario requiring about 450 kg Xe for the SEP stage, jettisoned at 3 AU. We interpret the SEP/REP propulsion as a competing alternative to solar sail and ballistic/REP propulsion. Omiting a Jupiter fly-by even allows more launch flexibility, leaving the mission duration in the range of the ESA specification.}, language = {en} } @inproceedings{OhndorfDachwaldSeboldtetal.2011, author = {Ohndorf, Andreas and Dachwald, Bernd and Seboldt, Wolfgang and Schartner, Karl-Heinz}, title = {Flight times to the heliopause using a combination of solar and radioisotope electric propulsion}, series = {32nd International Electric Propulsion Conference}, booktitle = {32nd International Electric Propulsion Conference}, pages = {1 -- 12}, year = {2011}, abstract = {We investigate the interplanetary flight of a low-thrust space probe to the heliopause,located at a distance of about 200 AU from the Sun. Our goal was to reach this distance within the 25 years postulated by ESA for such a mission (which is less ambitious than the 15-year goal set by NASA). Contrary to solar sail concepts and combinations of allistic and electrically propelled flight legs, we have investigated whether the set flight time limit could also be kept with a combination of solar-electric propulsion and a second, RTG-powered upper stage. The used ion engine type was the RIT-22 for the first stage and the RIT-10 for the second stage. Trajectory optimization was carried out with the low-thrust optimization program InTrance, which implements the method of Evolutionary Neurocontrol,using Artificial Neural Networks for spacecraft steering and Evolutionary Algorithms to optimize the Neural Networks' parameter set. Based on a parameter space study, in which the number of thrust units, the unit's specific impulse, and the relative size of the solar power generator were varied, we have chosen one configuration as reference. The transfer time of this reference configuration was 29.6 years and the fastest one, which is technically more challenging, still required 28.3 years. As all flight times of this parameter study were longer than 25 years, we further shortened the transfer time by applying a launcher-provided hyperbolic excess energy up to 49 km2/s2. The resulting minimal flight time for the reference configuration was then 27.8 years. The following, more precise optimization to a launch with the European Ariane 5 ECA rocket reduced the transfer time to 27.5 years. This is the fastest mission design of our study that is flexible enough to allow a launch every year. The inclusion of a fly-by at Jupiter finally resulted in a flight time of 23.8 years,which is below the set transfer-time limit. However, compared to the 27.5-year transfer,this mission design has a significantly reduced launch window and mission flexibility if the escape direction is restricted to the heliosphere's "nose".}, language = {en} } @techreport{Artmann2011, author = {Artmann, Gerhard}, title = {Plant mutant scanner : Hochdurchsatzscanner zur Charakterisierung von Pflanzenmutanten.

These topologies reflect the mostly unavoidable finiteness of the data, which limits the reliability of typically used estimators of signal interdependence. We propose random networks that are tailored to the way interaction networks are derived from empirical data.

The substrate is a fiber fraction obtained by organosolv pre-treatment of beech wood. For the ethanol production, a co-fermentation by two different yeasts (Saccharomyces cerevisiae and Pachysolen tannophilus) was carried out to convert glucose as well as xylose. Two approaches has been followed: 1. A two step process, in which the hydrolysis of the fiber fraction and the fermentation to product are separated from each other. 2. A process, in which the hydrolysis and the fermentation are carried out in one single process step as simultaneous saccharification and fermentation (SSF). Following the first approach, a yield of about 0.15 g ethanol per gram substrate can be reached. Based on the SSF, one process step can be saved, and additionally, the gained yield can be raised up to 0.3 g ethanol per gram substrate.}, language = {en} } @article{SiekerNeunerDimitrovaetal.2011, author = {Sieker, Tim and Neuner, Andreas and Dimitrova, Darina and Tippk{\"o}tter, Nils and Muffler, Kai and Bart, Hans-J{\"o}rg and Heinzle, Elmar and Ulber, Roland}, title = {Ethanol production from grass silage by simultaneous pretreatment, saccharification and fermentation: First steps in the process development}, series = {Engineering in Life Sciences}, volume = {11}, journal = {Engineering in Life Sciences}, number = {4}, publisher = {Wiley}, address = {Weinheim}, doi = {10.1002/elsc.201000160}, pages = {436 -- 442}, year = {2011}, abstract = {Grass silage provides a great potential as renewable feedstock.

In this study, we demonstrate the possibility to integrate the enzymatic pretreatment with a simultaneous saccharification and fermentation to achieve ethanol production from grass silage in a one-process step. Achieved yields were about 53 g ethanol per kg silage with the alkaline peroxide pretreatment and 91 g/kg with the enzymatic pretreatment at concentrations of 8.5 and 14.6 g/L, respectively.

The waveguides were based on a fin-line concept and the chamber containing the samples bathed in extracellular solution was placed onto two fins with a slot in between, where the exposure field concentrates. Measures were taken to allow for patch clamp recordings during radiofrequency (RF) exposure. The necessary power for the achievement of the maximum desired specific absorption rate (SAR) of 20 W/kg (average over the mass of the solution) was approximately Pin = 50 mW, Pin = 19 mW, and Pin = 18 mW for the 900 MHz, 1800 MHz, and 2 GHz devices, respectively. At 20 W/kg, a slight RF-induced temperature elevation in the solution of no more than 0.3 °C was detected, while no thermal offsets due to the electromagnetic exposure could be detected at the lower SAR settings (2, 0.2, and 0.02 W/kg). A deviation of 10\% from the intended solution volume yielded a calculated SAR deviation of 8\% from the desired value.

The prototype is characterized in numerical simulations and bench measurements, and the feasibility of plaque imaging at 7 T is demonstrated in first in vivo images. Materials and Methods: The RF phased array coil consists of 8 surface loop coils. To allow imaging of both sides of the neck, the RF array is divided into 2 coil clusters, each with 4 overlapping loop elements. For safety validation, numerical computations of the RF field distribution and the corresponding specific absorption rate were performed on the basis of a heterogeneous human body model. To validate the coil model, maps of the transmit B1+ field were compared between simulation and measurement. In vivo images of a healthy volunteer and a patient (ulcerating plaque and a 50\% stenosis of the right internal carotid artery) were acquired using a 3-dimensional FLASH sequence with a high isotropic spatial resolution of 0.54 mm as well as using pulse-triggered proton density (PD)/T2-weighted turbo spin echo sequences. Results: Measurements of the S-parameters yielded a reflection and isolation of the coil elements of better than -18 and -13 dB, respectively. Measurements of the g-factor indicated good image quality for parallel imaging acceleration factors up to 2.4. A similar distribution and a very good match of the absolute values were found between the measured and simulated B1+ transmit RF field for the validation of the coil model. In vivo images revealed good signal excitation of both sides of the neck and a high vessel-to-background image contrast for the noncontrast-enhanced 3-dimensional FLASH sequence. Imaging at 7 T could depict the extent of stenosis, and revealed the disruption and ulcer of the plaque. Conclusions: This study demonstrates that 2 four-channel transmit/receive RF arrays for each side of the neck is a suitable concept for in vivo MRI of the carotid arteries at 7 Tesla. Further studies are needed to explore and exploit the full potential of 7 T high-field MRI for carotid atherosclerotic plaque imaging.}, language = {en} } @article{OrzadaBitzSchaeferetal.2011, author = {Orzada, Stephan and Bitz, Andreas and Sch{\"a}fer, Lena C. and Ladd, Susanne C. and Ladd, Mark E. and Maderwald, Stefan}, title = {Open design eight-channel transmit/receive coil for high-resolution and real-time ankle imaging at 7 T}, series = {Medical Physics}, volume = {38}, journal = {Medical Physics}, number = {3}, publisher = {Wiley}, address = {Hoboken}, issn = {2473-4209}, doi = {10.1118/1.3553399}, pages = {1162 -- 1167}, year = {2011}, abstract = {Purpose: At 1.5 T, real-time MRI of joint movement has been shown to be feasible.

Methods: A U-shaped eight-channel transmit/receive array for the human ankle was built.urn:x-wiley:00942405:mp3399:equation:mp3399-math-0001-parameters and urn:x-wiley:00942405:mp3399:equation:mp3399-math-0002-factor were measured. SAR calculations of different ankle postures were performed to ensure patient safety. Inhomogeneities in the transmit field consequent to the open design were compensated for by the use of static RF shimming. High-resolution and real-time imaging was performed in human volunteers. Results: The presented array showed good performance with regard to patient comfort and image quality. High acceleration factors of up to 4 are feasible without visible acceleration artifacts. Reasonable image homogeneity was achieved with RF shimming.

In the present study we applied radio-frequency (RF) signals of the Universal Mobile Telecommunications System (UMTS) to full brain exposed male Wistar rats in order to elaborate putative influences on stress hormone release (corticosteron; CORT and adrenocorticotropic hormone; ACTH) and on hippocampal derived synaptic long-term plasticity (LTP) and depression (LTD) as electrophysiological hallmarks for memory storage and memory consolidation. Exposure was computer controlled providing blind conditions. Nominal brain-averaged specific absorption rates (SAR) as a measure of applied mass-related dissipated RF power were 0, 2, and 10 W/kg over a period of 120 min. Comparison of cage exposed animals revealed, regardless of EMF exposure, significantly increased CORT and ACTH levels which corresponded with generally decreased field potential slopes and amplitudes in hippocampal LTP and LTD. Animals following SAR exposure of 2 W/kg (averaged over the whole brain of 2.3 g tissue mass) did not differ from the sham-exposed group in LTP and LTD experiments. In contrast, a significant reduction in LTP and LTD was observed at the high power rate of SAR (10 W/kg). The results demonstrate that a rate of 2 W/kg displays no adverse impact on LTP and LTD, while 10 W/kg leads to significant effects on the electrophysiological parameters, which can be clearly distinguished from the stress derived background. Our findings suggest that UMTS exposure with SAR in the range of 2 W/kg is not harmful to critical markers for memory storage and memory consolidation, however, an influence of UMTS at high energy absorption rates (10 W/kg) cannot be excluded.}, language = {en} } @article{UmutluOrzadaKinneretal.2011, author = {Umutlu, Lale and Orzada, Stephan and Kinner, Sonja and Maderwald, Stefan and Bronte, Irina and Bitz, Andreas and Kraff, Oliver and Ladd, Susanne C. and Antoch, Gerald and Ladd, Mark E. and Quick, Harald H. and Lauenstein, Thomas C.}, title = {Renal imaging at 7 Tesla: preliminary results}, series = {European Radiology}, volume = {21}, journal = {European Radiology}, number = {4}, publisher = {Springer}, address = {Berlin}, issn = {1432-1084}, pages = {841 -- 849}, year = {2011}, abstract = {Objective To investigate the feasibility of 7T MR imaging of the kidneys utilising a custom-built 8-channel transmit/receive radiofrequency body coil. Methods In vivo unenhanced MR was performed in 8 healthy volunteers on a 7T whole-body MR system. After B0 shimming the following sequences were obtained: 1) 2D and 3D spoiled gradient-echo sequences (FLASH, VIBE), 2) T1-weighted 2D in and opposed phase 3) True-FISP imaging and 4) a T2-weighted turbo spin echo (TSE) sequence. Visual evaluation of the overall image quality was performed by two radiologists. Results Renal MRI at 7T was feasible in all eight subjects. Best image quality was found using T1-weighted gradient echo MRI, providing high anatomical details and excellent conspicuity of the non-enhanced vasculature. With successful shimming, B1 signal voids could be effectively reduced and/or shifted out of the region of interest in most sequence types. However, T2-weighted TSE imaging remained challenging and strongly impaired because of signal heterogeneities in three volunteers. Conclusion The results demonstrate the feasibility and diagnostic potential of dedicated 7T renal imaging. Further optimisation of imaging sequences and dedicated RF coil concepts are expected to improve the acquisition quality and ultimately provide high clinical diagnostic value.}, language = {en} } @article{KaramanidisAlbrachtBraunsteinetal.2011, author = {Karamanidis, Kiros and Albracht, Kirsten and Braunstein, Bjoern and Catala, Maria Moreno and Goldmann, Jan-Peter and Br{\"u}ggemann, Gert-Peter}, title = {Lower leg musculoskeletal geometry and sprint performance}, series = {Gait and Posture}, volume = {34}, journal = {Gait and Posture}, number = {1}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0966-6362}, doi = {10.1016/j.gaitpost.2011.03.009}, pages = {138 -- 141}, year = {2011}, abstract = {The purpose of this study was to investigate whether sprint performance is related to lower leg musculoskeletal geometry within a homogeneous group of highly trained 100-m sprinters.

In particular, it allows to numerically treat systems in which a laser field interacts with the medium with both its electric and magnetic component at the same time. The internal dynamics of the few-level system is modeled by a quantum optical master equation which includes coherent processes due to optical transitions driven by the laser fields as well as incoherent processes due to decay and dephasing. The propagation dynamics of the laser fields is treated in slowly varying envelope approximation resulting in a first order wave equation for each laser field envelope function. The program employs an Adams predictor formula second order in time to integrate the quantum optical master equation and a Lax-Wendroff scheme second order in space and time to evolve the wave equations for the fields. The source function in the Lax-Wendroff scheme is specifically adapted to allow taking into account the simultaneous coupling of a laser field to the polarization and the magnetization of the medium. To reduce execution time, a customized data structure is implemented and explained. In three examples the features of the program are demonstrated and the treatment of a system with a phase-dependent cross coupling of the electric and magnetic field component of a laser field is shown.}, language = {en} } @book{MeskourisHinzenButenwegetal.2011, author = {Meskouris, Konstantin and Hinzen, Klaus-G{\"u}nter and Butenweg, Christoph and Mistler, Michael}, title = {Bauwerke und Erdbeben : Grundlagen - Anwendung - Beispiele. - 3., aktualisierte und erweiterte Auflage}, edition = {3., aktualisierte und erweiterte Auflage}, publisher = {Vieweg + Teubner}, address = {Wiesbaden}, isbn = {978-3-8348-9856-2 (E-Book) ; 978-3-8348-0779-3 (Print)}, doi = {10.1007/978-3-8348-9856-2}, pages = {XVIII, 718 S.}, year = {2011}, language = {de} } @inproceedings{ButenwegMeskourisMeisteretal.2011, author = {Butenweg, Christoph and Meskouris, Konstantin and Meister, Sylvia and Dreyer, Stephan and Schulte-Althoff, Christoph}, title = {Technisches Informationssystem f{\"u}r die Entwicklung textilbewehrten Betons}, series = {Textilbeton in Theorie und Praxis : Tagungsband zum 6.

The prediction of reservoir temperature and production behavior is crucial for success of the proposed geothermal doublet. This work presents the results of a study of the important geothermal and geohydrological issues for the doublet design. In the first phase of the study, the influences of the three-dimensional (3D) structures of anticlines and synclines on the temperature field were examined. A comprehensive petrophysical investigation was performed to build a large scale 3D-model of the reservoir. Several bottomhole temperatures (BHTs), as well as petrophysical logs were used to calibrate the model using thermal conductivity measurements on 50 samples from boreholes in different lithological units in the study area. Profiles and cross sections extracted from the calculated temperature field were used to study the temperature in the surrounding areas of the planned doublet. In the second phase of the project, a detailed 3D numerical reservoir model was set up, with the aim of predicting the evolution of the producer and injector temperatures, and the extent of the cooled area around the injector. The temperature model from the first phase provided the boundary conditions for the reservoir model. Hydraulic parameters for the target horizons, such as porosity and permeability, were taken from data available from the nearby exploration wells. The simulation results are encouraging as no significant thermal breakthrough is predicted. For the originally planned location of the producer, the extracted water temperature is predicted to be around 79 °C, with an almost negligible cooling in the first 50 years of production. When the producer is located shallower parts of the reservoir, the yield water temperatures is lower, starting at ≈76 °C and decreasing to ≈74 °C after 50 years of operation. This comparatively larger decrease in temperature with time is caused by the structural feature of the reservoir, namely a higher dip causes the cooler water to easily move downward. In view of the poor reservoir data, the reservoir simulation model is constructed to allow iterative updates using data assimilation during planned drilling, testing, and production phases. Measurements during an 8 h pumping test carried out in late 2010 suggest that a flow rate of 150 m3 h-1 is achievable. Fluid temperatures of 76.5 °C were measured, which is very close to the predicted value.}, language = {en} } @inproceedings{KirschMattle2011, author = {Kirsch, Ansgar and Mattle, Bruno}, title = {Einflussfaktoren auf die Erddruckverteilung bei eingesch{\"u}tteten Tunneln}, series = {Baustatik Baupraxis : BB / Fachtagung Baustatik Baupraxis.

Here, we demonstrate that expression of microRNA (miR)-143 and 145 is upregulated in the liver of genetic and dietary mouse models of obesity. Induced transgenic overexpression of miR-143, but not miR-145, impairs insulin-stimulated AKT activation and glucose homeostasis. Conversely, mice deficient for the miR-143-145 cluster are protected from the development of obesity-associated insulin resistance. Quantitative-mass-spectrometry-based analysis of hepatic protein expression in miR-143-overexpressing mice revealed miR-143-dependent downregulation of oxysterol-binding-protein-related protein (ORP) 8. Reduced ORP8 expression in cultured liver cells impairs the ability of insulin to induce AKT activation, revealing an ORP8-dependent mechanism of AKT regulation. Our experiments provide direct evidence that dysregulated post-transcriptional gene silencing contributes to the development of obesity-induced insulin resistance, and characterize the miR-143-ORP8 pathway as a potential target for the treatment of obesity-associated diabetes.}, language = {en} } @article{HasegawaKapelyukhTaharaetal.2011, author = {Hasegawa, Maki and Kapelyukh, Yury and Tahara, Harunobu and Seibler, Jost and Rode, Anja and Krueger, Sylvia and Lee, Dongtao N. and Wolf, C.

Anschließend wurden zwei Bewertungs- und Steuerungsverfahren f{\"u}r einen Gasspeicher an den beiden Marktstufen Termin- und Spotmarkt methodisch vorgestellt und anhand von Beispielrechnungen illustriert. Das Verfahren zur Bewertung und Steuerung im Terminmarkt stellt ein sehr robustes und methodisch einfaches Verfahren dar. Hierbei wird die Saisonalit{\"a}t der Forwardkurve bzw. deren Ver{\"a}nderungen arbitragefrei mithilfe des Speichers ausgenutzt. Dieses Verfahren kann nicht den gesamten Zeitwert des Speichers ausweisen. Es zieht in jedem Zeitpunkt nur die aktuellen Informationen der Forwardkurve zur Entscheidung heran. Es bildet aber keine bedingte Erwartung {\"u}ber zuk{\"u}nftige Ertr{\"a}ge und deren Beeinflussung durch die aktuelle Speicherfahrweise, um hieraus eine optimale Entscheidung zu formulieren. Bei der Bewertung gegen{\"u}ber dem Spotmarkt mithilfe der Least-Squares-Monte- Carlo-Simulation wird in einer stochastischen Optimierung dagegen der volle Zeitwert des Speichers und damit der gesamte Zusatznutzen der Flexibilit{\"a}t ermittelt. Hierdurch leiten sich auch wesentlich andere Hedging-Empfehlungen als im ersten Verfahren ab, um diesen zu sichern. Der Einsatz der beiden Verfahren im Alltag zur Bewirtschaftung des Speichers h{\"a}ngt insbesondere vom Know-how, den Speicherparametern und der Risikobereitschaft des Handels ab. Beide Strategien liefern hierzu Hedging-Empfehlungen ab, mit welchem der zugrunde liegende Wert gesichert werden kann. Risikoaverse H{\"a}ndler, die einen Großteil des inneren Wertes sichern wollen, k{\"o}nnten im Terminmarkt einen Großteil des Speichers mithilfe des „Intrinsic Rolling"-Verfahrens bewirtschaften. Sie w{\"u}rden hierdurch den saisonalen Spread in der Forwardkurve rollierend sichern. Gleichzeitig kann ein kleinerer Anteil mithilfe der stochastischen Optimierung und den damit verbundenen Aus{\"u}bungsgrenzen gegen{\"u}ber dem Spotmarkt bewirtschaftet werden. In einem liquiden vollst{\"a}ndigen Markt wird eine Steuerung des Speichers allein gegen{\"u}ber den vorhandenen Marktstufen vorgenommen und der Wert f{\"u}r alle Marktteilnehmer objektiv messbar. F{\"u}r den Fall, dass der Markt illiquide ist und hierdurch z. B. eine Kundenlast nicht allein am Termin- und Spotmarkt jederzeit gedeckt werden kann, erscheint es notwendig, den Speicher im Kontext einer Portfoliooptimierung zu bewerten. Dies wird in der n{\"a}chsten Lektion vorgenommen. Hierbei ist aber zu beachten, dass der Speicher dadurch eine individualisierte Wertkomponente erh{\"a}lt, die von der konkreten Ausgestaltung des jeweiligen Portfolios abh{\"a}ngt.}, language = {de} } @incollection{FissabreNiethammer2011, author = {Fissabre, Anke and Niethammer, Bernd}, title = {Early Glazed Curtain Walls and their Preservation}, series = {Il vetro nell'architettura del XX secolo : conservazione e restauro = Glass in the 20th Century Architecture : Preservation and Restoration}, booktitle = {Il vetro nell'architettura del XX secolo : conservazione e restauro = Glass in the 20th Century Architecture : Preservation and Restoration}, editor = {Graf, Franz}, publisher = {Mendrisio Academy Press}, address = {Mendrisio}, isbn = {9788887624502}, pages = {185 -- 199}, year = {2011}, language = {en} } @article{Fissabre2011, author = {Fissabre, Anke}, title = {Dachterrassen der Renaissance - „Cosa pi{\`u} maravigliosa che gl'orti pensili di Babbilonia"}, series = {Architectura : Zeitschrift f{\"u}r Geschichte der Baukunst}, volume = {41}, journal = {Architectura : Zeitschrift f{\"u}r Geschichte der Baukunst}, number = {1}, publisher = {De Gruyter}, address = {Berlin}, issn = {0044-863X}, pages = {27 -- 46}, year = {2011}, language = {de} } @inproceedings{StieglitzWollert2011, author = {Stieglitz, Kristian and Wollert, J{\"o}rg}, title = {Approach of using ultra-wideband-radio in industrial real-time ethernet networks}, series = {The 4th International Multi-Conference on Engineering and Technological Innovation : IMETI : July 19th - July 22nd, 2011, Orlando, Florida, USA}, booktitle = {The 4th International Multi-Conference on Engineering and Technological Innovation : IMETI : July 19th - July 22nd, 2011, Orlando, Florida, USA}, organization = {International Multi-Conference on Engineering and Technological Innovation <4, 2011, Orlando, Fla.>}, pages = {1 -- 6}, year = {2011}, language = {en} } @inproceedings{BudaWollert2011, author = {Buda, Aurel and Wollert, J{\"o}rg}, title = {Leistungsbewertung von Ultra Wideband Funktechnologien nach ECMA 368 f{\"u}r den Einsatz in industriellen Kommunikationssystemen}, series = {Kommunikation in der Automation : Magdeburg, 27. - 28.09.2011 ; 2.
