In the course of the research, research was carried out to obtain a mathematical model of the physical similarity stand, processing of experimental data, refinement of the model, synthesis of the simplest algorithms for automatic control of single-loop systems. As a result of the research, a mathematical model was obtained that adequately describes the processes occurring in the system. It is planned to improve the model, implement a cognitive assistant, and provide digital planning
Integration von Nanostrukturen durch alternative Methoden: Mizellen-Deposition, Template-Wachstum und Nanogaps
This work is motivated by the aim to realize a higher integration density for storage elements in tomorrows microelectronic devices. This is achieved on the one hand by the application of novel materials with increased functionality and on the other hand through shrinking the device dimensions with the help of new structuring techniques. Three different approaches are studied: 1.) It is shown that the over all integration of binary or ternary oxidic materials between a crossbar array allows the realization of resistively switching RAMs within a CMOS process flow. 2.) TiO crystallization seeds are realized without standard lithography methods to provide a predefined way for the integration of the resistively switching materials. Self assembled diblock-copolymer micells are used as a hard mask in a CMOS-like process flow. 3.) To offer the possibility for studying candidates of future molecular electronics a prototype chip is realized. With the help of electron beam lithography the distance of two nanoelectrodes were reduced to 8nm. The narrow dimensions of the gap, the possibility to introduce a third electrode (quasi gate electrode) and the excellent behavior in liquid environment enables an good starting point for the electrical characterization of future nanoelectronic elements
Electrochemical Fabrication and Characterization of Nanocontacts and nm-sized Gaps
Comparison of pulmonary outcomes after off-pump coronary artery bypass (OPCAB) vs on-pump coronary artery grafting with cardiopulmonary bypass (CABG/CPB). Study design: We examined preoperative and postoperative respiratory compliance, fluid balance, hemodynamics, arterial blood gases, chest radiographs, spirometry, pulmonary complications, and time to extubation in a prospective trial of 200 patients randomized to OPCAB vs CABG/CPB performed by one surgeon.One CABG/CPB patient and two OPCAB patients required mitral valve repair or replacement and were withdrawn. After three crossovers from CABG/CBP to OPCAB and one crossover from OPCAB to CABG, 97 CABG/CPB patients and 100 OPCAB patients remained. There were no significant preoperative demographic differences between groups. Postoperative compliance was reduced more after OPCAB than after CABG/CPB (- 15.4 +/- 10.7 mL/cm H(2)O vs - 11.2 +/- 10.1 mL/cm H(2)O [mean +/- SD]; p = 0.007), associated with rotation of the heart into the right chest to perform posterolateral bypasses (p < 0.001) and the concomitant increased fluid requirements necessary to maintain hemodynamic stability during rotation of the heart. In addition to higher intraoperative fluid intake (4,541 +/- 1,311 mL vs 3,585 +/- 1,033 mL, p < 0.0001), OPCAB patients had higher intraoperative fluid balance (3,903 +/- 1,315 mL vs 1,772 +/- 1,373 mL, p < 0.0001), and higher postoperative pulmonary arterial diastolic pressure (15.0 +/- 5.5 mm Hg vs 11.8 +/- 5.2 mm Hg, p < 0.0001) and central venous pressure (10.4 +/- 4.5 mm Hg vs 8.4 +/- 4.7 mm Hg, p < 0.0001). Despite lower compliance, immediate postoperative Pao(2) on fraction of inspired oxygen of 1.0 (275 +/- 97 torr vs 221 +/- 92 torr, p = 0.001) was higher after OPCAB and extubation was earlier (p = 0.001). Postoperative chest radiographs, spirometry, mortality, reintubation, or readmission for pulmonary complications were not different between groups.Compared to CABG/CPB, OPCAB was associated with a greater reduction in postoperative respiratory compliance associated with increased fluid administration and rotation of the heart into the right chest to perform posterolateral grafts. OPCAB yielded better gas exchange and earlier extubation but no difference in chest radiographs, spirometry, or rates of death, pneumonia, pleural effusion, or pulmonary edema
