We report on the realization of a 3D terahertz imaging system for industrial radome inspection. The system has been designed to be operated within a machining center for radome manufacturing. In order to provide the required flexibility in respect to image resolution and penetration depth, we developed a system, which combines two frequency-modulated continuous-wave terahertz sensing units, operating...
This paper describes a contingency-based approach to ensemble classification. Motivated by a business marketing problem, we explore the use of decision tree models, along with diversity measures and other elements of the task domain, to identify highly-performing ensemble classification models. Working from generated data sets, we found that 1) decision tree models can significantly improve the identification...
Managed care is placing severe financial and organizational pressures on healthcare institutions, while at the same time capitation and competition are limiting resources. In response, institutions are beginning to re-engineer themselves from revenue to cost centers. Research indicates that of the three major clinical service components that comprise the healthcare system (surgical, medical, and mental...
Permanent magnet (PM) excited synchronous machines used in modern drives for electro-mobiles suffer in high speed regions from the limited battery-voltage. The field weakening requires machine designs with reduced power conversion properties or oversize of the power converter. A new concept of such machine features PM excitation, single teeth winding and an additional circumferential excitation coil...
From 10 theses about traction motors approaches to overcome the drawbacks of permanent magnet and induction machines are derived. Efficiency can be improved at both groups of machines by optimized control and more sophisticated topologies. Verification of the improvements were done by measurements in the lab. Design aspects for system integration of power electronics are specified.
