For this, we combine the native speed of an abstract real-time operating system (RTOS) model in SystemC with dynamic binary translation for fast Instruction Set Simulation (ISS) by QEMU. In order to support stepwise RTOS software refinement from system level to the target software, each task can be separately migrated between the native execution and the ISS. By adapting the dynamic binary translation approach to an efficient but yet very accurate synchronization scheme the overhead of QEMU user mode execution is only factor two compared to native SystemC. Furthermore, the simulation speed increases almost linearly according to the utilization of the task set abstracted by the native execution. Hereby, the simulation time can be considerably reduced by cosimulating just a subset of tasks on QEMU."}],"citation":{"bibtex":"@inproceedings{Becker_Zabel_Müller_2010, place={Dordrecht}, title={A Mixed Level Simulation Environment for Stepwise RTOS Software Refinement}, DOI={<a href=\"https://doi.org/10.1007/978-3-642-15234-4_15\">10.1007/978-3-642-15234-4_15</a>}, publisher={Springer Verlag}, author={Becker, Markus and Zabel, Henning and Müller, Wolfgang}, editor={Kleinjohann, L. and Kleinjohann, B.}, year={2010} }","chicago":"Becker, Markus, Henning Zabel, and Wolfgang Müller. “A Mixed Level Simulation Environment for Stepwise RTOS Software Refinement.” edited by L.

Specifically, we present a rigorous generalization of the most common multivariate statistical analysis techniques to the case of quaternion vectors, and show that the different kinds of quaternion improperness require different kinds of widely linear processing. In general, the optimal linear processing is \\emph{full-widely linear}, which requires the joint processing of the quaternion vector and its involutions over three pure unit quaternions. However, in the case of jointly $\\mathbbQ$-proper and $\\mathbbC^{\\eta}$-proper vectors, the optimal processing reduces, respectively, to the \\emphconventional and \\emph{semi-widely linear processing}, with the latter only requiring to operate on the quaternion vector and its involution over the pure unit quaternion $\\eta$.

The analysis of the mixed analogue and digital structure of charge-pump phase-locked loops (CP-PLL) is a challenge in modelling and simulation. In most cases the system is designed and characterized using its continuous linear model or its discrete linear model neglecting its non-linear switching behaviour. I.e., the time-varying model is approximated by a time-invariant representation using its average dynamics. Depending on what kind of phase detector is used, the scopes of validity of these approximations are different. Here, a preeminent characterization and simulation technique based on the systems event-driven feature is presented, merging the logical and analogue inherent characteristics of the system. In particular, the high-grade non-linear locking process and the dead-zone are analyzed.\r\n                    </jats:p>","lang":"eng"}]},{"type":"journal_article","department":[{"_id":"59"}],"date_created":"2023-01-24T12:14:16Z","abstract":[{"text":"<jats:p>Abstract. By the rising complexity and miniaturisation of the device's dimensions, the density of the conductors increases considerably. Referring to this, locally transient interactions between single physical values become apparent. Therefore, for the investigation and optimisation of integrated circuits it is essential to develop suitable models and simulation surroundings which allow for memory and time-efficient calculation of the behaviour. By means of the dynamic reconstruction theory and the radial basis functions nets the so-called black box models are provided. The description of black box models is derived from the input and output behaviour or so-called time series of a dynamic system. Concerning the time series, the black box model adapts its parameters via the extended Kalman filter. This paper provides a modelling approach that enables fast and efficient simulations.\r\n                    </jats:p>","lang":"eng"}],"publication":"Advances in Radio Science","doi":"10.5194/ars-6-139-2008","language":[{"iso":"eng"}],"date_updated":"2023-03-22T10:32:22Z","publication_status":"published","intvolume":"         6","title":"Macro-modelling via radial basis functionen nets","year":"2010","publication_identifier":{"issn":["1684-9973"]},"author":[{"full_name":"Wiegand, C.","first_name":"C.","last_name":"Wiegand"},{"last_name":"Fischer","first_name":"C.","full_name":"Fischer, C."},{"first_name":"R.","last_name":"Kazemzadeh","full_name":"Kazemzadeh, R."},{"full_name":"Hedayat, C.","first_name":"C.","last_name":"Hedayat"},{"first_name":"W.","last_name":"John","full_name":"John, W."},{"id":"20179","full_name":"Hilleringmann, Ulrich","first_name":"Ulrich","last_name":"Hilleringmann"}],"citation":{"apa":"Wiegand, C., Fischer, C., Kazemzadeh, R., Hedayat, C., John, W., &#38; Hilleringmann, U.

The central quantity is the transverse spin susceptibility, from which the complete excitation spectrum, including single-particle spin-flip Stoner excitations and collective spin-wave modes, can be obtained. The susceptibility is derived from many-body perturbation theory and includes dynamic correlation through a summation over ladder diagrams that describe the coupling of electrons and holes with opposite spins. In contrast to earlier studies, we do not use a model potential with adjustable parameters for the electron-hole interaction but employ the random-phase approximation. To reduce the numerical cost for the calculation of the four-point scattering matrix we perform a projection onto maximally localized Wannier functions, which allows us to truncate the matrix efficiently by exploiting the short spatial range of electronic correlation in the partially filled d or f orbitals. Our implementation is based on the full-potential linearized augmented-plane-wave method. Starting from a ground-state calculation within the local-spin-density approximation (LSDA), we first analyze the matrix elements of the screened Coulomb potential in the Wannier basis for the 3d transition-metal series. In particular, we discuss the differences between a constrained nonmagnetic and a proper spin-polarized treatment for the ferromagnets Fe, Co, and Ni. The spectrum of single-particle and collective spin excitations in fcc Ni is then studied in detail. The calculated spin-wave dispersion is in good overall agreement with experimental data and contains both an acoustic and an optical branch for intermediate wave vectors along the [100] direction. In addition, we find evidence for a similar double-peak structure in the spectral function along the [111] direction. To investigate the influence of static correlation we finally consider LSDA+U as an alternative starting point and show that, together with an improved description of the Fermi surface, it yields a more accurate quantitative value for the spin-wave stiffness constant, which is overestimated in the LSDA."}],"date_created":"2020-08-28T11:31:26Z","file":[{"creator":"schindlm","date_created":"2020-08-28T11:33:17Z","description":"© 2010 American Physical Society","file_size":711970,"access_level":"open_access","file_name":"PhysRevB.81.054434.pdf","date_updated":"2020-08-30T15:06:10Z","relation":"main_file","content_type":"application/pdf","file_id":"18561","title":"Wannier-function approach to spin excitations in solids"}],"department":[{"_id":"296"},{"_id":"35"},{"_id":"15"},{"_id":"170"},{"_id":"230"}],"type":"journal_article"},{"year":"2010","title":"Enhanced FDTD edge correction for nonlinear effects calculation","author":[{"full_name":"Classen, C","last_name":"Classen","first_name":"C"},{"id":"158","last_name":"Förstner","orcid":"0000-0001-7059-9862","first_name":"Jens","full_name":"Förstner, Jens"},{"full_name":"Meier, Torsten","last_name":"Meier","first_name":"Torsten","orcid":"0000-0001-8864-2072","id":"344"},{"last_name":"Schuhmann","first_name":"R","full_name":"Schuhmann, R"}],"publication_identifier":{"isbn":["9781424449675","9781424449682"]},"date_updated":"2025-12-16T12:35:39Z","publication_status":"published","article_number":"11515155 ","language":[{"iso":"eng"}],"doi":"10.1109/aps.2010.5562017","publication":"2010 IEEE Antennas and Propagation Society International Symposium","abstract":[{"text":"The electromagnetic field in the vicinity of sharp edges needs a special treatment in numeric calculation whenever accurate, fast converging results are necessary. One of the fundamental works concerning field singularities has been proposed in 1972 [1] and states that the electromagnetic energy density must be integrable over any finite\r\ndomain, even if this domain contains singularities. It is shown, that the magnetic field \u0002H(\u0003, ϕ) and electric field \u0002E(\u0003, ϕ) are proportional to ∝ \u0003(t−1) for \u0003 → 0. The variable \u0003 is the distance to the edge and t has to fulfill the integrability condition and thus is restricted to 0 < t < 1. This result is often used to reduce the error corresponding to the singularity without increasing the numerical effort [2 - 5]. For this purpose, a correction factor K is estimated by inserting the proportionality into the wave equation. It is shown, that this method improves the accuracy of the result significantly, however the order of convergence is often not studied. In [4] a method to modify the material parameters in order to use analytic results to improve the numeric calculation is presented. In this contribution we will - inspired by the scheme given in [4] - develop a new method to estimate a correction factor for perfect conducting materials (PEC) and demonstrate the improvement of the results compared to the standard edge correction. Therefore analytic results (comparable to [1]) are consequently merged with the scheme in [4]. The main goal of this work is the calculation of the second harmonic generation (SHG) in the wave response of so-called metamaterials [6]. Frequently these structures\r\ncontain sharp metallic edges with field singularities at the interfaces which have a strong impact on the SHG signals. Thus, an accurate simulation of singularities is highly important. However, the following approach can also be applied to many other setups, and one of them is shown in the example below.","lang":"eng"}],"file":[{"date_created":"2018-08-28T08:36:44Z","creator":"hclaudia","file_id":"4168","content_type":"application/pdf","file_name":"2010 Classen,Förstner, Meier T,Schuhmann_Enhanced FDTD edge correction for nonlinear effects calculation.pdf","file_size":209412,"access_level":"open_access","relation":"main_file","date_updated":"2018-09-04T19:31:42Z"}],"date_created":"2018-08-28T08:34:52Z","keyword":["tet_topic_numerics"],"type":"conference","department":[{"_id":"61"},{"_id":"15"},{"_id":"293"},{"_id":"170"},{"_id":"230"},{"_id":"35"},{"_id":"34"}],"status":"public","conference":{"location":"Toronto, ON, Canada","name":"2010 IEEE international Symposium Antennas","start_date":"2010-07-11","end_date":"2010-07-17"},"has_accepted_license":"1","_id":"4167","publisher":"IEEE","urn":"41677","ddc":["530"],"user_id":"16199","file_date_updated":"2018-09-04T19:31:42Z","citation":{"ieee":"C.

Coagulation is treated as cluster–cluster agglomeration along the line connecting the center of mass of both agglomerates and is implemented using a Monte Carlo algorithm. Sintering is modeled as successive overlapping of spheres which cause reduction in the surface area based on a rate law for surface reduction. Surface growth is modeled as an increase in primary particle diameter, e.g. as a result of surface reactions. The evolved aggregates are analyzed by calculating their fractal dimension, radius of gyration, mobility diameter and mobility shape factor. It is found that the aggregates structure tends to be more compact when introducing the surface growth in shorter time comparing to the coagulation-sintering step only. Fractal dimension and the mobility shape factor of the resulting aggregates are correlated to an effective dimensionless time that combines the characteristic times of these three fundamental mechanisms. It is shown that the mobility diameter in the free molecular regime is not proportional to the radius of gyration. A power law relation that correlates the aggregates projected area and the equivalent number of primary particles is found to be in a very good agreement with estimates published in literature.","lang":"eng"}],"citation":{"bibtex":"@article{Al Zaitone_Schmid_Peukert_2009, title={Simulation of structure and mobility of aggregates formed by simultaneous coagulation, sintering and surface growth}, volume={40}, DOI={<a href=\"https://doi.org/10.1016/j.jaerosci.2009.08.007\">10.1016/j.jaerosci.2009.08.007</a>}, number={11}, journal={Journal of Aerosol Science}, author={Al Zaitone, Belal and Schmid, Hans-Joachim and Peukert, Wolfgang}, year={2009}, pages={950–964} }","chicago":"Al Zaitone, Belal, Hans-Joachim Schmid, and Wolfgang Peukert. “Simulation of Structure and Mobility of Aggregates Formed by Simultaneous Coagulation, Sintering and Surface Growth.” <i>Journal of Aerosol Science</i> 40, no. 11 (2009): 950–64. <a href=\"https://doi.org/10.1016/j.jaerosci.2009.08.007\">https://doi.org/10.1016/j.jaerosci.2009.08.007</a>.","short":"B.

For a fundamental understanding of particle sintering characteristics, the neck growth kinetics in agglomerate chains and in doublets consisting of differently sized primary particles is investigated. Results show that different sintering contacts in agglomerates even during the first stages are not completely independent from each other, even though differences are small. The neck growth kinetics of differently sized primary particles is determined by the smaller one up to a size difference by a factor of approximately 2, whereas for larger size differences, the kinetics becomes faster. In particular, the agglomerate sintering kinetics is investigated for particle chains of different lengths and for different particle morphologies each having ten primary particles and nine initial sintering contacts. For agglomerate chains, the kinetics approximately can be normalized by using the radius of the fully coalesced sphere. In general, different agglomerate morphologies show equal kinetics during the first sintering stages, whereas during advanced stages, compact morphologies show significantly faster sintering progress than more open morphologies. Hence, the overall kinetics cannot be described by simply using constant morphology correction factors such as fractal dimension or mean coordination number which are used in common sintering models. However, for the first stages of viscous-flow agglomerate sintering, which are the most important for many particle processes, a sintering equation is presented. Although we use agglomerates consisting of spherical primary particles, our methodology can be applied to other aggregate geometries as well.","lang":"eng"}]},{"status":"public","title":"Body fat and animal protein intakes are associated with adrenal androgen secretion in children","year":"2009","publication_identifier":{"issn":["0002-9165","1938-3207"]},"author":[{"first_name":"Lijie","last_name":"Shi","full_name":"Shi, Lijie"},{"last_name":"Wudy","first_name":"Stefan A","full_name":"Wudy, Stefan A"},{"full_name":"Buyken, Anette","first_name":"Anette","last_name":"Buyken","id":"65985"},{"full_name":"Hartmann, Michaela F","last_name":"Hartmann","first_name":"Michaela F"},{"first_name":"Thomas","last_name":"Remer","full_name":"Remer, Thomas"}],"date_updated":"2022-01-06T06:57:30Z","publication_status":"published","page":"1321-1328","_id":"26893","language":[{"iso":"eng"}],"doi":"10.3945/ajcn.2009.27964","user_id":"61597","publication":"The American Journal of Clinical Nutrition","citation":{"chicago":"Shi, Lijie, Stefan A Wudy, Anette Buyken, Michaela F Hartmann, and Thomas Remer. “Body Fat and Animal Protein Intakes Are Associated with Adrenal Androgen Secretion in Children.” <i>The American Journal of Clinical Nutrition</i>, 2009, 1321–28. <a href=\"https://doi.org/10.3945/ajcn.2009.27964\">https://doi.org/10.3945/ajcn.2009.27964</a>.","short":"L.
