Im Rahmen des vorgestellten Forschungsvorhabens konnte gezeigt werden, dass die bestehenden Grenzen des gepulsten Laserstrahlschweißens von Aluminiumlegierungen erweitert werden können. Im Projekt wurde die Erstarrungsgeschwindigkeit als primäre steuernde Größe hinsichtlich der Rissentstehung adressiert. Mithilfe von Hochgeschwindigkeitsaufnahmen a...

We study spectral problems for two-dimensional integral system with two given non-decreasing functions R, W on an interval [0, b) which is a generalization of the Krein string. Associated to this system are the maximal linear relation \(T_{\max }\) and the minimal linear relation \(T_{\min }\) in the space \(L^2(dW)\) which are connected by \(T_{\m...

We study spectral problems for two--dimensional integral system with two given non-decreasing functions $R_1$, $R_2$ on an interval $[0,b)$ which is a generalization of the Krein string. Associated to this system are the maximal linear relation $T_{\max}$ and the minimal linear relation $T_{\min}$ in the space $L^2(R_2)$ which are connected by $T_{...

We consider initial boundary-value problem for acoustic equation in the time space cylinder Ω × (0; 2T) with unknown variable speed of sound, zero initial data, and mixed boundary conditions. We assume that (Neumann) controls are located at some part Σ Ω [0; T]; Σ ⊂ 𝜕Ω of the lateral surface of the cylinder Ω × (0; T). The domain of observation is...

Let P, Q and W be real functions of locally bounded variation on [0,∞) and let W be non-decreasing. In the case of absolutely continuous functions P, Q and W the following Sturm-Liouville type integral system: (see [5]) is a special case of so-called canonical differential system (see [16, 20, 24]). In [27] a maximal A max and a minimal A min linea...
