In dieser Arbeit werden dreidimensionale Kennwerte benutzt, um die Oberflächenqualität von Laser-Sinter Bauteiloberflächen und die Einflüsse aus unterschiedlichen Bereichen der gesamten Prozesskette zu evaluieren. Beispielsweise wurden objektive Kennwerte, mit deren Hilfe Orangenhaut zu identifizieren ist, und Prozessparameter, die diese deutlich vermindern, gefunden. Mittels Durchführung von haptischen Versuchen wurde das subjektive Empfinden ermittelt und konnten zu objektiven Kennwerten korreliert werden. Eine mikroskopische Betrachtung des flachen Oberflächenwinkels mit verschieden farbigen Pulvern zeigt neue Erkenntnisse zum Anschmelzvorgang von Partikeln an die Schmelze. Zur nachträglichen Glättung von Oberflächen wurden mechanische, chemische und optische Nachbehandlungsmethoden verwendet und deren Potential aufgezeigt. Eine abschließende neuartige Simulation der dreidimensionalen Topografie bildet die Grundlage für ein Programm zur automatischen und funktionsgerechten Orientierung von Bauteilen, welche am Beispiel eines realen Bauteils erfolgreich validiert wurde. Zusammengenommen zeigen die Ergebnisse, dass die richtige Wahl von Bauorientierung und Prozessparametern entscheidend für die Bauteilqualität ist und selbst eine aufwendige Nachbearbeitung eine ungeschickte Wahl derer nur schwerlich ausgleichen kann.\r\n","lang":"ger"}]},{"type":"journal_article","year":"2021","citation":{"chicago":"Kessler, Jan, Francesco Calcavecchia, and Thomas Kühne. “Artificial Neural Networks as Trial Wave Functions for Quantum Monte Carlo.” Advanced Theory and Simulations 4, no. 4 (2021). https://doi.org/10.1002/adts.202000269.","ama":"Kessler J, Calcavecchia F, Kühne T.

Investigated micro FE-simulations show that the matrix of UD composites exhibits different average plastic behaviour, named as average asymmetric matrix plasticity (AAMP), when the composite behaves different under shear, longitudinal and transverse loadings. In this study, a non-linear mean-field debonding model (NMFDM) combining a mean-field model and a fibre–matrix interface debonding model, is developed to simulate UD composites under consideration of AAMP, fibre–matrix interface damage and progressive failure. AAMP is considered by using so-called stress mode factor, which is expressed in terms of basic invariants of the matrix deviatoric stress tensor and is used as an indicator for detection of differences in the loading mode. The material behaviour of UD composites with imperfect interface is assumed identical as for perfect interface and stiffness reduced fibres. Progressive failure criteria are established with consideration of fibre breakage and matrix crack for different fibre orientations. As a representative example for the NMFDM, a C30/E201 UD composite is studied. To verify the model, experiments are conducted on polymers, carbon fibres and UD CFRPs. Finally, the model is applied to simulate a perforated CFRP laminate, which shows excellent prediction ability on deformation, debonding and progressive failure."}],"user_id":"335","year":"2021","type":"journal_article","citation":{"apa":"Cheng, C., Wang, Z., Jin, Z., Ju, X., Schweizer, S., Tröster, T., & Mahnken, R.

This paper presents a novel method based on limited\r\ndata from sensors positioned at specific locations and guarantees a general accordance of reality and\r\nsimulation in terms of multimodal road traffic counts and vehicle speeds. In these considerations, the actual\r\npurpose of research is of particular importance. Here, the research aims at improving the traffic flow by\r\ncontrolling the Traffic Light Systems (TLS) of the examined area which is why the current traffic state and\r\nthe route choices of individual road users are the matter of interest.

Many process parameters affect the bond strength, such like the bond normal force, ultrasonic power, wire material and bonding frequency. Today, process design, development, and optimization is most likely based on the knowledge of process engineers and is mainly performed by experimental testing. In this contribution, a newly developed simulation tool is presented, to reduce time and costs and efficiently determine optimized process parameter. Based on a co-simulation of MATLAB and ANSYS, the different physical phenomena of the wire bonding process are considered using finite element simulation for the complex plastic deformation of the wire and reduced order models for the transient dynamics of the transducer, wire, substrate and bond formation. The model parameters such as the coefficients of friction between bond tool and wire and between wire and substrate were determined for aluminium and copper wire in experiments with a test rig specially developed for the requirements of heavy wire bonding. To reduce simulation time, for the finite element simulation a restart analysis and high performance computing is utilized. Detailed analysis of the bond formation showed, that the normal pressure distribution in the contact between wire and substrate has high impact on bond formation and distribution of welded areas in the contact area.","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"https://doi.org/10.1016/j.microrel.2021.114077","date_updated":"2023-09-21T14:15:33Z","publication_status":"published","publication_identifier":{"issn":["0026-2714"]},"department":[{"_id":"151"}],"title":"Co-simulation of MATLAB and ANSYS for ultrasonic wire bonding process optimization"},{"title":"Mechanical joining of glass fibre reinforced polymer (GFRP) through an innovative solid self-piercing rivet","publication_status":"published","publication_identifier":{"issn":["0924-0136"]},"department":[{"_id":"157"}],"doi":"10.1016/j.jmatprotec.2021.117182","date_updated":"2023-10-16T19:22:21Z","language":[{"iso":"eng"}],"user_id":"65085","volume":296,"date_created":"2023-01-21T10:32:47Z","status":"public","publication":"Journal of Materials Processing Technology","keyword":["Industrial and Manufacturing Engineering","Metals and Alloys","Computer Science Applications","Modeling and Simulation","Ceramics and Composites"],"author":[{"first_name":"Daxin","full_name":"Han, Daxin","last_name":"Han","id":"36544"},{"first_name":"Keke","full_name":"Yang, Keke","last_name":"Yang","id":"65085"},{"first_name":"Gerson","orcid":"0000-0002-2763-1246","full_name":"Meschut, Gerson","last_name":"Meschut","id":"32056"}],"quality_controlled":"1","publisher":"Elsevier BV","article_number":"117182","intvolume":" 296","_id":"37822","citation":{"chicago":"Han, Daxin, Keke Yang, and Gerson Meschut. “Mechanical Joining of Glass Fibre Reinforced Polymer (GFRP) through an Innovative Solid Self-Piercing Rivet.” Journal of Materials Processing Technology 296 (2021). https://doi.org/10.1016/j.jmatprotec.2021.117182.","apa":"Han, D., Yang, K., & Meschut, G.

As a result, the use of aluminum alloys is continuously increasing. Due to poor weldability of aluminum in combination with other materials, mechanical joining technologies like clinching are increasingly used. In order to predict relevant characteristics of clinched joints and to ensure the reliability of the process, it is simulated numerically during product development processes. In this regard the predictive accuracy of the simulated process highly depends on the implemented friction model. In particular, the frictional behavior between the sheet metals affects the geometrical formation of the clinched joint significantly. This paper presents a testing method, which enables to determine the frictional coefficients between sheet metal materials for the simulation of clinching processes. For this purpose, the correlation of interface pressure and the relative velocity between aluminum sheets in clinching processes is investigated using numerical simulation. Furthermore, the developed testing method focuses on the specimen geometry as well as the reproduction of the occurring friction conditions between two sheet metal materials in clinching processes. Based on a methodical approach the test setup is explained and the functionality of the method is proven by experimental tests using sheet metal material EN AW6014.

This approach involves so-called Huygens' box as an efficient radiation model inside an electromagnetic (EM) simulation tool and then transforms the scanned NF measured data into the FF. For this, the basic idea of the Huygens'box principle and the NF-to-FF transformation are briefly presented. The NF is measured on the Huygens' box around a device under test using anNF scanner, recording the magnitude and phase of the site-related magnetic and electric components. A comparison between a fullwave simulation and the measurement results shows a good similarity in both the NF and the simulated and transformed FF.Thus, this method is applicable to predict the FF behaviour of any electronic system by measuring the NF. With this knowledge, the RF design can be improved due to allowing a significant reduction of EM compatibility failure at the end of the development flow. In addition, the very efficient FF radiation model can be used for detailed investigations in various environments and the impact of such an equivalent radiation source on other electronic systems can be assessed.","lang":"eng"}],"status":"public","date_created":"2021-03-18T13:49:49Z","author":[{"first_name":"Dominik","full_name":"Schröder, Dominik","last_name":"Schröder"},{"first_name":"Sven","full_name":"Lange, Sven","last_name":"Lange","id":"38240"},{"first_name":"Christian","full_name":"Hangmann, Christian","last_name":"Hangmann"},{"last_name":"Hedayat","first_name":"Christian","full_name":"Hedayat, Christian"}],"publisher":" The Institution of Engineering and Technology (IET)","publication":"Tensorial Analysis of Networks (TAN) Modelling for PCB Signal Integrity and EMC Analysis","keyword":["Huygens' box","NF-to-FF transformation","efficient FF radiation model","FF behaviour","EMI assessment","PCB","near-field measurements","efficient radiation model","far-field behaviour","RF design process","far-field prediction","Huygens'box principle","fullwave simulation","electronic system radiation","equivalent radiation source","electromagnetic simulation tool","near-field scan data","EM compatibility failure reduction"],"doi":"10.1049/pbcs072e_ch14","date_updated":"2022-01-06T06:55:03Z","language":[{"iso":"eng"}],"related_material":{"record":[{"status":"public","id":"21542","relation":"other"}]},"title":"Far-field prediction combining simulations with near-field measurements for EMI assessment of PCBs","place":"Croyton, UK","project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"publication_identifier":{"isbn":["9781839530494","9781839530500"]},"publication_status":"published","edition":"1","department":[{"_id":"485"}]},{"title":"Numerical analysis of the robustness of clinching process considering the pre-forming of the parts ","user_id":"34782","author":[{"full_name":"Bielak, Christian Roman","first_name":"Christian Roman","id":"34782","last_name":"Bielak"},{"id":"45779","last_name":"Böhnke","full_name":"Böhnke, Max","first_name":"Max"},{"id":"38279","last_name":"Beck","full_name":"Beck, Robert","first_name":"Robert"},{"first_name":"Mathias","full_name":"Bobbert, Mathias","last_name":"Bobbert","id":"7850"},{"id":"32056","last_name":"Meschut","orcid":"0000-0002-2763-1246","full_name":"Meschut, Gerson","first_name":"Gerson"}],"publisher":"Elsevier","keyword":["Clinching","process simulation","FEM","pre-straining","sensitivity analysis"],"publication":"Journal of Advanced Joining Processes.

A \r\nsteeper elevation angle would result in a more balanced seasonal PV yield, at the cost of PV yield reductions during \r\nsummer, but allowing reduced storage capacities. Additionally, the effect of a single-axis tracking system has been \r\ninvestigated, generating more electricity during the morning and evening hours, thus reducing daily storage \r\nrequirements. The necessary PV size and storage capacities required for the German energy supply (1,500 TWh after \r\nelectrification of all sectors) via 100% renewable energies and a 50% solar share have been calculated via the \r\nHOMER Pro software, considering the bridging of periods of \"dark lulls“ in winter, using costs of 2030 (Table 1). \r\nResults: The increase of module elevation angles above the typical 30° leads to a reduction of investment and supply \r\ncosts. The optimum is reached at a cost reduction of -1.5% for an elevation angle at the latitude of the installation \r\nsite. An explanation is that high elevation angles are favorable for clear winter days, but not at all for the critical days \r\nwith diffuse irradiance only, so the battery capacity must be increased. For the same reason, tracking systems do not \r\noffer any cost advantage (at least for the ones without an option for horizontal positioning during diffuse days)."}],"user_id":"28836","ddc":["620"],"file":[{"content_type":"application/pdf","date_updated":"2022-01-06T13:41:20Z","relation":"main_file","success":1,"file_size":428312,"file_id":"29178","creator":"krauter","access_level":"closed","date_created":"2022-01-06T13:41:20Z","file_name":"Krauter Rustemovic Khatibi - Elevated Angle - EUPVSEC 2020.pdf"}],"quality_controlled":"1","author":[{"first_name":"Stefan","orcid":"0000-0002-3594-260X","full_name":"Krauter, Stefan","last_name":"Krauter","id":"28836"},{"last_name":"Rustemovic","full_name":"Rustemovic, D.","first_name":"D."},{"last_name":"Khatibi","id":"43538","first_name":"Arash","full_name":"Khatibi, Arash"}],"publication":"Proceedings of the 37th European Photovoltaic Solar Energy Conference, 07 - 11 September 2020","keyword":["Energy Storage","PV system integration","Large Grid-connected PV systems","Simulation","Energy Supply Options"],"file_date_updated":"2022-01-06T13:41:20Z","status":"public","has_accepted_license":"1","date_created":"2020-09-14T12:42:30Z"},{"type":"journal_article","year":"2020","citation":{"short":"E.

Self-adaptive user interfaces (SAUIs) have been promoted as a solution for context variability due to their ability to automatically adapt to the context-of-use at runtime. The development of SAUIs is a challenging and complex task as additional aspects like context management and UI adaptation have to be covered. In classical model-driven UI development approaches, these aspects are not fully integrated and hence introduce additional complexity as they represent crosscutting concerns. In this paper, we present an integrated model-driven development approach where a classical model-driven development of UIs is coupled with a model-driven development of context-of-use and UI adaptation rules. We base our approach on the core UI modeling language IFML and introduce new modeling languages for context-of-use (ContextML) and UI adaptation rules (AdaptML). The generated UI code, based on the IFML model, is coupled with the context and adaptation services, generated from the ContextML and AdaptMLmodel, respectively. The integration of the generated artifacts, namely UI code, context, and adaptation services in an overall rule-based execution environment, enables runtime UI adaptation. The benefit of our approach is demonstrated by two case studies, showing the development of SAUIs for different application scenarios and a usability study which has been conducted to analyze end-user satisfaction of SAUIs."}],"language":[{"iso":"eng"}],"doi":"10.1007/s10270-020-00777-7","date_updated":"2022-02-02T08:58:33Z","publication_status":"published","publication_identifier":{"issn":["1619-1366","1619-1374"]},"department":[{"_id":"34"},{"_id":"66"}],"title":"Integrated model-driven development of self-adaptive user interfaces"},{"type":"journal_article","year":"2020","citation":{"short":"E.

Anhand von Fallturmtests an hybriden Demonstratorkomponenten konnte das modifizierte Nasspressverfahren für die Herstellung crashrelevanter Karosseriebauteile qualifiziert werden.","lang":"ger"}],"user_id":"15952","keyword":["Leichtbau","Faserverbundkunststoffe","Nasspressverfahren","Hybridbauteile","Rheologie","Klebtechnik","Co-Bonding"],"author":[{"last_name":"Opdemom","first_name":"Hermann","full_name":"Opdemom, Hermann"}],"publisher":"Shaker Verlag","date_created":"2023-02-10T11:24:40Z","status":"public","volume":"2019,35"},{"abstract":[{"text":"Ultraschall wird zur Effizienzsteigerung in verfahrenstechnischen Prozessen eingesetzt. Die Betriebsparamter der Ultraschallsysteme werden empirisch ermittelt, da derzeit keine systematische Analyse der Wechselwirkung zwischen Ultraschallwandler und Schallfeld sowie kein Verfahren zur Messung der Kavitationsaktivität ohne zusätzlichen Sensor existieren. Auf Basis einer experimentellen Analyse des betrachteten sonochemischen Reaktors wird ein Finite-Elemente-Modell aufgebaut, das die Wechselwirkung zwischen Schallfeld und Ultraschallwandler berücksichtigt. Die modellbasierte Analyse zeigt, dass wegen der akustischen Eigenschaften des Autoklavs nur direkt an der Sonotrode Kavitation entsteht. Die Wechselwirkung zwischen Ultraschallwandler und Schallfeld ermöglicht Aussagen über das Schallfeld und die Kavitationsaktivität auf Basis der Rückwirkung auf den Ultraschallwandler. Die lineare Schalldruckverteilung ermöglicht eine Prognose über die Verteilung von Kavitationszonen. Das beschriebene Modell liefert wertvolle Erkenntnisse für die Auslegung, Analyse und Skalierung sonochemischer Reaktoren. Auf Grund der rauen Prozessrandbedingungen ist die Applikation von Sensoren zur Überwachung der Kavitationsaktivität in vielen sonochemischen Prozessen nicht möglich. Zur prozessbegleitenden Messung der Kavitationsaktivität wird ein Verfahren entwickelt, das die Bewertung der Kavitationsaktivität durch Auswertung der Rückwirkung auf den Ultraschallwandler erlaubt. Das Messverfahren ermöglicht eine vorhersagbare und reproduzierbare Durchführung kavitationsbasierter Prozesse und stellt eine wichtige Erweiterung für bestehende und neue Ultraschallsysteme dar.","lang":"eng"}],"title":"Modellierung und experimentelle Charakterisierung der Wechselwirkung zwischen Ultraschallwandler und Flüssigkeit in kavitationsbasierten Prozessen","user_id":"210","author":[{"last_name":"Bornmann","first_name":"Peter","full_name":"Bornmann, Peter"}],"publisher":"Shaker","keyword":["Sonochemie","Akustische Kavitation","Kavitationsmessung","Kavitationsdetektion","FEM-Simulation Ultraschallwandler","Prozessüberwachung","FEM-Simulation Schallfeld","Self-Sensing","Piezoelektrische Ultraschallwandler","Ultraschallreinigung"],"department":[{"_id":"151"}],"status":"public","date_created":"2019-05-27T10:29:53Z","date_updated":"2023-09-15T12:23:55Z","_id":"10000","year":"2019","citation":{"ieee":"P.

Fine powdersare primarily defined by the fact that adhesive and cohesive forces outweigh the weight forces, leadingto mostly unwanted agglomeration (clumping) and adhesion to surfaces. Thereby it gets more difficult touse conventional conveyor systems (e.g. pneumatic or vibratory conveyors) for transport. A rather newmethod for transporting these fine powders is based on ultrasonic vibrations, which are used to reducefriction between powder and substrate. Within this contribution an experimental set-up consisting of apipe, a solenoid actuator for axial vibration and an annular piezoelectric actuator for the high frequencyradial vibration of the pipe is described. Since amplitudes of the radial pipe vibration should be as large aspossible to get high effects of friction reduction, the pipe is excited to vibrate in resonance. To determinethe optimum excitation frequency and actuator position the vibration modes and resonance frequenciesof the pipe are calculated and measured.

When introducing copper as wire material for high power applications, adaptations to the bonding process and to machines became necessary. Here, challenges occur due to the stiffer wire material and changing oxide layers on the contact partners. To achieve sufficient process stability, a clean bond area is required, which can only be achieved with high shear stresses in the contact partners surfaces. These necessitate high normal forces to plastically deform the wire and substrate. To achieve such high stresses in the contact area, the bonding tool needs to be able to transmit the needed tangential forces to the top side of the wire. The wire itself performs a shear movement and transmits the force into the contact area to clean the contaminant and oxide layers and to level the desired bond surfaces. The main function of the tool is to transmit these forces. If the bond tool can only transmit low forces in the direction of excitation, the parameter space for a stable bond process is severely restricted. Here, a modeling approach to estimate how well different tool shapes meet the demand of transmitting high tangential forces is presented. The model depends on wire deformation and thus on the ultrasonic softening effect.","lang":"eng"}]},{"series_title":"AAMAS '14","year":"2014","type":"conference","citation":{"short":"G. Polevoy, S.

Typical examples are crankshafts, camshafts, differential gear or hydraulic pumps. In the operating state the elastomeric seal ring and the shaft are separated by a lubrication film of just a few micrometers. Due to shear strain and fluid friction the contact area is subject to a higher temperature than the rest of the seal ring. The stiffness of the elastomeric material is intensely influenced by this temperature and thus contact pressure, friction and wear also strongly depend on the contact temperature. In order to simulate the contact behavior of elastomer seal rings it is essential to use a comprehensive approach which takes into consideration the interaction of temperature, friction and wear. Based on this idea a macroscopic simulation model has been developed at the MEGT. It combines a finite element approach for the simulation of contact pressure at different wear states, a semi-analytical approach for the calculation of contact temperature and an empirical approach for the calculation of friction. In this paper the model setup is presented, as well as simulation and experimental results.","lang":"eng"}],"extern":"1","user_id":"38077","language":[{"iso":"eng"}],"date_updated":"2022-12-15T10:20:39Z","doi":"https://doi.org/10.1016/j.wear.2013.12.030","department":[{"_id":"146"}],"publication_identifier":{"issn":["0043-1648"]},"title":"A comprehensive model of wear, friction and contact temperature in radial shaft seals"},{"_id":"17202","date_updated":"2023-02-01T16:11:59Z","year":"2014","citation":{"ieee":"A.-L.

These motors can operate in ``stick-slip'' or ``slip-slip'' mode, with the fundamental frequency of the driving signal ranging from several Hertz to more than 100 kHz. To predict the motor characteristics, a Coulomb friction model is sufficient in many cases, but numerical simulation requires microscopic time steps. This contribution proposes a much faster simulation technique using one evaluation per period of the excitation signal. The proposed technique produces results very close to those of timestep simulation for ultrasonics inertia motors and allows direct determination of the steady-state velocity of an inertia motor from the motion profile of the driving part. Thus it is a useful simulation technique which can be applied in both analysis and design of inertia motors, especially for parameter studies and optimisation.","lang":"eng"}],"publication_identifier":{"issn":["1948-5719"]},"status":"public","date_created":"2019-05-13T13:20:17Z","quality_controlled":"1","author":[{"full_name":"Hunstig, Matthias","first_name":"Matthias","last_name":"Hunstig"},{"last_name":"Hemsel","full_name":"Hemsel, Tobias","first_name":"Tobias"},{"last_name":"Sextro","first_name":"Walter","full_name":"Sextro, Walter"}],"keyword":["friction","ultrasonic motors","Coulomb friction model","efficient simulation technique","friction contact","high-frequency piezoelectric inertia motor","motor characteristics prediction","numerical simulation","slip-slip mode","stick-slip mode","time-step simulation","ultrasonic inertia motor","Acceleration","Acoustics","Actuators","Computational modeling","Friction","Numerical models","Steady-state"],"publication":"Ultrasonics Symposium (IUS), 2012 IEEE International","department":[{"_id":"151"}],"doi":"10.1109/ULTSYM.2012.0068","_id":"9784","date_updated":"2022-01-06T07:04:20Z","year":"2012","citation":{"chicago":"Hunstig, Matthias, Tobias Hemsel, and Walter Sextro. “An Efficient Simulation Technique for High-Frequency Piezoelectric Inertia Motors.” In Ultrasonics Symposium (IUS), 2012 IEEE International, 277–80, 2012. https://doi.org/10.1109/ULTSYM.2012.0068.","ama":"Hunstig M, Hemsel T, Sextro W.

For this process compounding extruders are used which mostly involve tightly intermeshing, co-rotating twin screw extruders. These extruders consist of two closely spaced screws which rotate in the same direction and convey the raw material to the screw tip. These screws are surrounded by several barrel modules which heat or cool the material. As the whole design of the machine is modularly arranged the process behavior of a twin screw extruder depends for the main part on the arrangement of the screw and the barrel elements. Until today this arrangement and process optimization is conducted by experienced engineers and with the help of trial-and-error methods. Furthermore, theoretical models are used with which the behavior of the extruder is estimated. As these models are mostly very complex they are only made available with the realization in different software projects. One of the tools is called SIGMA. Within this paper SIGMA is introduced as a software to optimize a twin screw extruder.

It has been defined in terms of child-directed speech (Motherese), child-directed motion (Motionese), and contingency. In the field of developmental robotics, research often assumes that in human-robot interaction (HRI), robots are treated similar to infants, because their immature cognitive capabilities benefit from this behavior. However, according to our knowledge, it has barely been studied whether this is true and how exactly humans alter their behavior towards a robotic interaction partner. In this paper, we present results concerning the acceptance of a robotic agent in a social learning scenario obtained via comparison to adults and 8-11 months old infants in equal conditions. These results constitute an important empirical basis for making use of tutoring behavior in social robotics. In our study, we performed a detailed multimodal analysis of HRI in a tutoring situation using the example of a robot simulation equipped with a bottom-up saliency-based attention model. Our results reveal significant differences in hand movement velocity, motion pauses, range of motion, and eye gaze suggesting that for example adults decrease their hand movement velocity in an Adult-Child Interaction (ACI), opposed to an Adult-Adult Interaction (AAI) and this decrease is even higher in the Adult-Robot Interaction (ARI). We also found important differences between ACI and ARI in how the behavior is modified over time as the interaction unfolds. These findings indicate the necessity of integrating top-down feedback structures into a bottom-up system for robots to be fully accepted as interaction partners."}],"status":"public","date_created":"2020-06-24T13:02:43Z","author":[{"last_name":"Vollmer","first_name":"Anna-Lisa","full_name":"Vollmer, Anna-Lisa"},{"first_name":"Katrin Solveig","full_name":"Lohan, Katrin Solveig","last_name":"Lohan"},{"last_name":"Fischer","full_name":"Fischer, Kerstin","first_name":"Kerstin"},{"first_name":"Yukie","full_name":"Nagai, Yukie","last_name":"Nagai"},{"last_name":"Pitsch","first_name":"Karola","full_name":"Pitsch, Karola"},{"full_name":"Fritsch, Jannik","first_name":"Jannik","last_name":"Fritsch"},{"full_name":"Rohlfing, Katharina","first_name":"Katharina","id":"50352","last_name":"Rohlfing"},{"last_name":"Wrede","first_name":"Britta","full_name":"Wrede, Britta"}],"publisher":"IEEE","publication":"Development and Learning, 2009.

Multi-context devices are one promising approach to overcome the limitations posed by long reconfiguration times. In contrast to more traditional reconfigurable architectures, multi-context devices hold several configurations on-chip. On demand, the device can quickly switch to another context. In this paper we present a co-simulation environment to investigate design trade-offs for hybrid multi-context architectures. Our architectural model comprises a reconfigurable unit closely coupled to a CPU core. As a case study, we discuss the implementation of a FIR filter partitioned into several contexts.

We consider explicitly declared signals, ports, local variables, and shared variables. Our specification defines an abstract VHDL ’ 93 interpreter in the form of transition rules for an evolving algebra machine (EA-Machine) [60]. It faithfully reflects and supports the view of simulation given in the IEEE VHDL ’ 93 standard language reference manual. The definition can be understood without any prior formal training.
