We report the design and performance of a packaged broadband PM hybrid HDFA/TDFA in the 2000–2100 nm band using all-single-clad doped fibers. Internal small signal G = 49.1 dB, small signal NF = 6.5 dB, and P out = 3.54 W are achieved at λ s = 2051 nm. The simulated 3 dB output power bandwidth is 98 nm. Comparisons of experimental data and simulati...
Mit der Neurons Platform hat Ivanti ein Cloudangebot geschaffen, das Unternehmen bei der proaktiven Störungsbehebung insbesondere für geografisch und logisch verteilte Endpunkte helfen will. Die Neurons for Healing erkennen Fehlerzustände im besten Fall bereits, bevor Anweder davon Notiz nehmen und leiten Gegenmaßnahmen ein.
Research question: Team and project work has become increasingly important in recent years. Although the direct environment has a great influence on the quality of teamwork, the design of a team-oriented working environment has hardly been researched. Methodology: The empirical basis of the study is an online survey which was subsequently evaluated...
In maritime shipping, weather routing systems are popular to reduce fuel consumption and emissions. One of the most comprehensive overviews of applied optimization approaches to date has been compiled as part of this thesis. To ensure applicability for various types of ships and to reduce data requirements, weather-dependent ship motions and fuel c...
The remarkable properties of graphene and related materials (GRMs) promise substantial benefits for a wide range of technologies. Their industrial utilization, however, critically depends on the availability of suitable GRM supply in terms of both quality and quantity at a competitive price. All factors remain highly specific to the each applicatio...
This study monitored for the first time the occurrence of a wide range of very volatile organic compounds (VVOCs) as emissions from wooden materials and in indoor air of prefabricated wooden houses non-occupied and occupied. Measurements were performed by using a newly developed method which enables a broadening of the analytical spectrum beyond ≤ ...
Ice-building up on the leading edge of wings and other surfaces exposed to icing atmospheric conditions can negatively influence the aerodynamic performances of aircrafts. In the past, research activities focused on understanding icing phenomena and finding effective countermeasures. Efforts have been dedicated to creating coatings capable of reduc...
Strong band bending within crystalline silicon is important for improving carrier selectivity in the contact regions of silicon heterojunction solar cells. In this work, we compare the use of capacitance-voltage as an alternative to the surface photovoltage method for probing the built-in voltage associated with crystalline silicon band bending. Th...
The fused filament fabrication (FFF) technique was applied for the first time to fabricate novel 3D printed silicate bioactive and antibacterial Ag-doped glass-ceramic (Ag-BG) scaffolds. A novel filament consisting primarily of polyolefin and Ag-BG micro-sized particles was developed and its thermal properties characterized by thermogravimetric ana...
Aim: Diagnostics is a prerequisite for effective and efficient treatment of complex diseases. Consequently, the progress of medicine requires the development of innovative diagnostic devices from the early product idea to market maturity. However, this complex process is not always perceived holistically so that technical and economic dimensions ar...
