Recent neural mapping frameworks show promising results, but rely on RGB-D or pose inputs, or cannot run in real-time. To address these limitations, our approach integrates dense-SLAM with neural implicit fields. Specifically, our dense SLAM approach runs parallel tracking and global optimization, while a neural field-based map is constructed incrementally based on the latest SLAM estimates. For the efficient construction of neural fields, we employ multi-resolution grid encoding and signed distance function (SDF) representation. This allows us to keep the map always up-to-date and adapt instantly to global updates via loop closing. For global consistency, we propose an efficient $Sim(3)$-based pose graph bundle adjustment (PGBA) approach to run online loop closing and mitigate the pose and scale drift. To enhance depth accuracy further, we incorporate learned monocular depth priors. We propose a novel joint depth and scale adjustment (JDSA) module to solve the scale ambiguity inherent in depth priors. Extensive evaluations across synthetic and real-world datasets validate that our approach outperforms existing methods in accuracy and map completeness while preserving real-time performance.Guided by model quality: UAV path planning for complete and precise 3D reconstruction of complex buildingshttps://puma.ub.uni-stuttgart.de/bibtex/2548684606428a96e876c6eda8f36fd2c/markusenglichmarkusenglich2024-01-22T14:49:59+01:00journal review <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="Shuhang Zhang" itemprop="url" href="/person/11f11c4663c5f524ba8c30d8dfc65d961/author/0"><span itemprop="name">S.

Unmanned aerial vehicle (UAV) photogrammetry offers a cost-effective solution, but complex buildings with self-occlusion pose challenges to reconstruction quality. Conventional flight paths often result in incomplete and imprecise models. This study presents a novel multirotor UAV path planning method for achieving complete and precise 3D reconstruction of complex buildings. A coarse model is obtained from common flight paths as input, its quality factors including completeness and precision are considered. By detecting incomplete or occluded areas, additional viewpoints are strategically planned to enhance completeness while adhering to photogrammetric constraints. Furthermore, precision is improved by adding viewpoints based on error ellipsoids of target points. Real-world experiments demonstrate that the proposed method increases incomplete area coverage by up to 21% and enables centimetre-level accuracy reconstruction with reduced uncertainties. The method holds promise for georeferenced inspection and documentation of complex buildings.Virtual Fuel Cell System Development with Physics- and Data Based Models; Conference on Renewable Energy Carriers, Stuttgarthttps://puma.ub.uni-stuttgart.de/bibtex/271b6d43a898b3afd861b251abd264226/puma_ifspuma_ifs2023-12-21T18:00:05+01:00FKFS IFS Journal AP <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="M.

Mater.

Utilizing highly doped Ge1-xSnx alloys grown on Si substrates is one promising route to enable device operation at near-infrared (NIR) wavelengths. Due to the lower effective mass of electrons in Sn compared to Ge, the incorporation of Sn can potentially lower the plasma wavelength of Ge1-xSnx alloys compared to that of pure Ge. However, defects introduced by the large lattice mismatch to Si substrates as well as the introduction of alloy scattering limit device applications in practice. Here, we investigate pulsed laser melting as one strategy to increase material quality in highly doped Ge1-xSnx alloys. We show that a pulsed laser melting treatment of our Ge1-xSnx films not only serves to lower the material’s plasma frequency but also leads to an increase in active dopant concentration. We demonstrate the application of this material in plasmonic gratings with sharp optical extinction peaks at MIR wavelengths.High mobility Ge 2DHG based MODFETs for low-temperature applicationshttps://puma.ub.uni-stuttgart.de/bibtex/2fd41330edf7a4fef360189deeb07fb39/ihtpublikationihtpublikation2023-11-02T08:53:40+01:00iht journal <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="David Weißhaupt" itemprop="url" href="/person/1fdd3f3971915cf0bb940e6e1523fef99/author/0"><span itemprop="name">D.

The Ge 2DHG is particularly interesting, since Ge exhibits the highest hole mobility among all semiconductors. In this paper, we report on the temperature-dependent direct current-characteristics of normally-on MODFETs based on a high mobility Ge 2DHG. Here, we specifically investigate device characteristics down to cryogenic temperatures and analyze the impact of different MOD-doping on device performance. We find that the largest On-Off ratio of and lowest sub-threshold swing (SS) of at a temperature of are attained for a MOD-doping of , while the highest effective mobility is obtained from a device with a MOD-doping of . Furthermore, while effective mobilities in the devices are strongly reduced compared to Hall mobilities measured in the unstructured Ge 2DHGs, both quantities can be seen to follow a similar trend. Our results motivate further investigations of Ge 2DHG MODFETs for applications in cryogenic low-noise amplifiers, besides their well-established potential for spintronic applications.High mobility Ge 2DHG based MODFETs for low-temperature applications - IOPscienceAnalog Multiplexer for Performance Enhancement of Digital-to-Analog Converters and Experimental 2-to-1 Time Interleaving in 28-nm FD-SOI CMOShttps://puma.ub.uni-stuttgart.de/bibtex/22ceb3630dc5b267906685e071eac149e/wolfgangvogelwolfgangvogel2023-10-19T08:07:49+02:00Journal int pr-dac128g <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="Daniel Widmann" itemprop="url" href="/person/1af25faf09a7a23bcf8e5c2947e2270d3/author/0"><span itemprop="name">D.

These methods extend the existing schemes by addressing both bilateral and unilateral constraints, as well as set-valued Coulomb friction. The Lobatto IIIA-IIIB methods presented in this paper make a substantial contribution to the ongoing endeavor of developing event-capturing versions of high-order schemes. By stating a generalized version of the principle of virtual action for nonsmooth mechanical systems, the integrators are derived from an appropriate discretization of it. The discrete contact laws are found by discretizing the impenetrabilty condition as well as the Newton-type frictional impact laws in an event-capturing way. The presented discrete contact laws exhibit no contact penetration and satisfy the involved unilateral constraints both on position and on velocity level. This behavior is showcased using benchmark examples.
