Particularly in the automotive sector, lightweight design principles continue to prosper rapidly. As a result, adjusted materials for different applications were developed. Due to the formation of intermetallic phases, most multi-material mixes cannot be welded and require adapted joining technologies. Mechanical joining technologies such as self-piercing riveting and mechanical clinching have proven effective methods of joining lightweight materials like aluminium and ductile steels. New high-strength steels are increasingly used in crash-sections, where limited deformation under impact load is required. These hot stamped steels have a very low elongation at break and therefore a low formability. Currently there is no joining by forming technology without pre-punching available using these grades of steels on die-side. The newly developed shear-clinching process is one possible method of joining this kind of material without additional elements. The fundamental idea of shear-clinching is a single-stage process in which pre-punching of the die-side material is performed by indirect shear-cutting and subsequent forming of the upper layer into this hole. This would immensely enlarge the application segment of mechanical clinching even if hot stamped steels are positioned on die-side. Fundamental studies are required to ensure process reliability and it is necessary to break down the joining process into fragments, like pre-punching and clinching with pre-punched sheet, and superpose them to form the combined procedure shear-clinching. This paper presents a detailed investigation of the sub-process clinching with pre-hole.}}, author = {{Merklein, Marion and Meschut, Gerson and Müller, Martin and Hörhold, Réjane}}, issn = {{1662-9795}}, journal = {{Key Engineering Materials}}, keywords = {{Mechanical Engineering, Mechanics of Materials, General Materials Science}}, pages = {{1413--1420}}, publisher = {{Trans Tech Publications, Ltd.}}, title = {{{Basic Investigations of Non-Pre-Punched Joining by Forming of Aluminium Alloy and High Strength Steel with Shear-Clinching Technology}}}, doi = {{10.4028/www.scientific.net/kem.611-612.1413}}, volume = {{611-612}}, year = {{2014}}, } @article{42902, author = {{Shnayien, Marie-Luise}}, journal = {{onlinejournal kultur & geschlecht}}, number = {{13}}, pages = {{1--18}}, title = {{{Der rosafarbene Elefant im Raum.

However, the intrinsic multimode spectral-temporal structure of pulsed PDC often poses a severe hindrance for the direct implementation of the heralding of pure single-photon states or, for example, continuous-variable entanglement distillation experiments. To get rid of multimode effects narrowband frequency filtering is frequently applied to achieve a single-mode behavior. A rigorous theoretical description to accurately describe the effects of filtering on PDC, however, is still missing. To date, the theoretical models of filtered PDC are rooted in the discrete-variable domain and only account for filtering in the low-gain regime, where only a few photon pairs are emitted at any single point in time. In this paper we extend these theoretical descriptions and put forward a simple model, which is able to accurately describe the effects of filtering on PDC in the continuous-variable domain. This developed straightforward theoretical framework enables us to accurately quantify the tradeoff between suppression of higher-order modes, reduced purity, and lowered Einstein–Podolsky–Rosen entanglement, when narrowband filters are applied to multimode type-II PDC.}}, author = {{Christ, Andreas and Lupo, Cosmo and Reichelt, Matthias and Meier, Torsten and Silberhorn, Christine}}, issn = {{1050-2947}}, journal = {{Physical Review A}}, number = {{2}}, title = {{{Theory of filtered type-II parametric down-conversion in the continuous-variable domain: Quantifying the impacts of filtering}}}, doi = {{10.1103/physreva.90.023823}}, volume = {{90}}, year = {{2014}}, } @inproceedings{43914, abstract = {{Ultra-intense and CEP-stable waveforms in the multi-THz range control dynamical Bloch oscillations and interband polarization in bulk GaSe, leading to the emission of all-coherent high-order harmonics covering 12.7 optical octaves from THz to VIS regimes.}}, author = {{Meier, Torsten and Hohenleutner, M. and Schubert, O. and Langer, F. and Urbanek, B. and Lange, C. and Huttner, U. and Golde, D. and Kira, M. and Koch, S.W. and Huber, R.}}, booktitle = {{19th International Conference on Ultrafast Phenomena}}, isbn = {{1-55752-279-0}}, location = {{Okinawa Japan}}, title = {{{Phase-locked multi-THz high-harmonic generation by dynamical bloch oscillations in bulk semiconductors}}}, doi = {{10.1364/UP.2014.10.Thu.A.3}}, year = {{2014}}, } @article{22955, abstract = {{The dynamics of 3D Airy-vortex wave packets is studied under the action of strong self-focusing Kerr nonlinearity.

The rapid collapse imposes a severe limitation on the propagation of multidimensional waves in Kerr media. However, the structure of the Airy beam carrier allows the coupling of light from the leading, most intense peak into neighboring peaks and consequently strongly postpones the collapse. The dependence of the critical input amplitude for the appearance of a fast collapse on the beam width is studied for wave packets with zero and nonzero topological charges.
