Past earthquakes showed the social and political consequences of seismic damage to industrial facilities and sensitized the population and politicians worldwide for the possible hazard emanating from industrial facilities. However, a holistic approach for the seismic design of industrial facilities can presently neither be found in national nor in international standards. The introduction of EN 1998-4 of the new generation of Eurocode 8 will improve the normative situation with specific seismic design rules for silos, tanks and pipelines and secondary process components. The article presents essential aspects of the seismic design of industrial facilities based on the new generation of Eurocode 8 using the example of tank structures and secondary process components. The interaction effects of the process components with the primary structure are illustrated by means of the experimental results of a shaking table test of a three story moment resisting steel frame with different process components.

The visualization and interpretation of sensor data is typically based on simple spreadsheets and non-standardized user-oriented solutions, which makes it difficult for building owners, facility managers and decision-makers to evaluate and understand the data. The solution of this problem in the future are integrated BIM-Sensor approaches which allow the generation of BIM models incorporating all relevant information of monitoring systems. These approaches support both the dynamic visualization of key structural performance parameters, the effective long-term management of sensor data based on BIM and provide a user-friendly interface to communicate with various stakeholders. A major benefit for the end user is the use of the BIM software architecture, which is the future standard anyway. In the following, the application of the integrated BIM-Sensor approach is illustrated for a typical industrial facility as a part of an early warning and rapid response system for earthquake events currently developed in the research project "ROBUST" with financial support by the German Federal Ministry for Economic Affairs and Energy (BMWI).}, language = {en} } @article{BussmannEngelsFussetal.2000, author = {Bussmann, N. and Engels, R. and Fuss, L. and Kemmerling, G. and Reinartz, R. and Langen, K.-J. and Schelten, J. and Ziemons, Karl}, title = {Performance measurement of a new high resolution detector system for I-131 thyroid studies}, series = {2000 IEEE Nuclear Science Symposium Conference Record, Vol. 3}, journal = {2000 IEEE Nuclear Science Symposium Conference Record, Vol. 3}, issn = {1082-3654}, pages = {22/35 -- 22/37}, year = {2000}, abstract = {A 2-dimensional detector system for high resolution thyroid I-131 scintigraphy was developed.

In addition to the need to ensure optimal thermal operating conditions of the drivetrain components (drive motor, battery and electrical components), thermal comfort must be provided for the passengers. Thermal comfort is defined as the feeling which expresses the satisfaction of the passengers with the ambient conditions in the compartment. The influencing factors on thermal comfort are the temperature and humidity as well as the speed of the indoor air and the clothing and the activity of the passengers, in addition to the thermal radiation and the temperatures of the interior surfaces. The generation and the maintenance of free visibility (ice- and moisture-free windows) count just as important as on-demand heating and cooling of the entire vehicle. A Carsharing climate concept of the innovative ec2go vehicle stipulates and allows for only seating areas used by passengers to be thermally conditioned in a close-to-body manner. To enable this, a particular feature has been added to the preconditioning of the Carsharing electric vehicle during the electric charging phase at the parking station.}, language = {en} } @inproceedings{BuschkuehleSchuermannWollert2009, author = {Buschk{\"u}hle, Peter and Sch{\"u}rmann, Volker and Wollert, J{\"o}rg}, title = {Abstraction of wireless communication by a convergence middleware in conjunction with a XML-configuration}, series = {Information technology and electrical engineering : devices and systems, materials and technologies for the future ; Ilmenau 07 - 10 September 2009 ; 54.

Multivariate analysis using principal component analysis (PCA), soft independent modelling of class analogy (SIMCA), and partial least squares - discriminant analysis (PLS-DA) were applied for the modelling of spectral data. Different pre-processing methods were applied to IR spectral data; multiplicative scatter correction (MSC) was chosen as the most relevant.

A new method for the processing of asymmetric tensor fields is proposed restricting our attention to tensors of second-order given by a 2x2 array or matrix with real entries. This is achieved by a transformation resulting in Hermitian matrices that have an eigendecomposition similar to symmetric matrices. With this new idea numerical results for real-world data arising from a deformation of an object by external forces are given.

The suitability of the models was demonstrated by cross validation (CV) as well as by an independent validation set of samples from different biomass origins (beech wood and wheat straw).

The prediction errors for the validation samples were in a similar range for the partial least squares model from the 1H NMR data and for a multiple linear regression using the DOSY NMR data.

Here we present a method using 1H spectra of benchtop as well as conventional NMR systems in combination with multivariate data analysis, to determine lignin's molecular weight (Mw and Mn) and polydispersity index (PDI). A set of 36 organosolv lignin samples (from Miscanthus x giganteus, Paulownia tomentosa and Silphium perfoliatum) was used for the calibration and cross validation, and 17 samples were used as external validation set. Validation errors between 5.6\% and 12.9\% were achieved for all parameters on all NMR devices (43, 60, 500 and 600 MHz). Surprisingly, no significant difference in the performance of the benchtop and high-field devices was found. This facilitates the application of this method for determining lignin's molecular weight in an industrial environment because of the low maintenance expenditure, small footprint, ruggedness, and low cost of permanent magnet benchtop NMR systems.}, language = {en} } @article{BuniatyanMatirosyanAbouzaretal.2009, author = {Buniatyan, Vahe V. and Matirosyan, N. and Abouzar, Maryam H. and Schubert, J. and Zander, W. and Gevorgian, S. and Sch{\"o}ning, Michael Josef and Poghossian, Arshak}, title = {Capacitive field-effect pH sensor based on an electrolyte-ferroelectric-insulator-semiconductor structure}, series = {SENSOR 2009 : : 14th International Conference on Sensors, Technologies, Electronics and Applications; N{\"u}rnberg, Germany, 26 - 28 May 2009; proceedings; [part of] Sensor + Test Conference 2009 / AMA, Fachverband f{\"u}r Sensorik e.V}, journal = {SENSOR 2009 : : 14th International Conference on Sensors, Technologies, Electronics and Applications; N{\"u}rnberg, Germany, 26 - 28 May 2009; proceedings; [part of] Sensor + Test Conference 2009 / AMA, Fachverband f{\"u}r Sensorik e.V}, publisher = {AMA Service}, address = {Wunstorf}, isbn = {9783981099355}, pages = {317 -- 322}, year = {2009}, language = {en} } @article{BuniatyanAbouzarMartirosyanetal.2010, author = {Buniatyan, Vahe V. and Abouzar, Maryam H. and Martirosyan, Norayr W. and Schubert, J{\"u}rgen and Gevorgian, Spartak and Sch{\"o}ning, Michael Josef and Poghossian, Arshak}, title = {pH-sensitive properties of barium strontium titanate (BST) thin films prepared by pulsed laser deposition technique}, series = {Physica Status Solidi (A). 207 (2010), H. 4}, journal = {Physica Status Solidi (A). 207 (2010), H. 4}, isbn = {1862-6300}, pages = {824 -- 830}, year = {2010}, language = {en} } @article{BuniatyanMatirosyanAbouzaretal.2009, author = {Buniatyan, V.
