Optical Spring Stabilization
… one aspect that will limit us in the future: angular stability of the test masses. Angular stability in advanced LIGO uses an active feedback system. We are proposing to replace the active feedback system with a passive one, eliminating sensing noise contributions. This technique uses the …

Design of metasurfaces for detection system application
… Metasurface absorbers (MTAs) with improved angular stability performance, suitable bandwidth and certain conformability are introduced and a comparison with literature contributions supports this enhanced behavior. Furthermore, a MTA is combined with an antenna to reduce its Radar Cross …

Costruzione di uno scaffold vascolarizzato per la chirurgia ortopedica
… In all cases the synthesis was performed with angular stability plates and a stable synthesis achieved. All patients have been controlled at a mean follow-up of 10.5 months (from 2 to 16 ). In all case but one the bone-scaffold osteo-integration was achieved at an average of 38 days at the …

Frequency selective surface (FSS) for cellular signals shelding
… square loop FSS printed on paper shows a good angular stability compared to the conventional square loop FSS printed on FR-4 substrate. The utilization of the inkjet printing technique is proposed in order to overcome the limitations of the manual fabrication technique. In order to transform a …

On-line Dynamic Security Assessment in Power Systems.
… will be less predictable. Consequently, today's stability and security assessment tools, which are generally dependent on extensive off-line studies, may no longer be feasible in their current development state. A core component of an efficient on-line dynamic security assessment is a fast and …

Das DHS-Prinzip in der Versorgung proximaler Humerusfrakturen
BACKGROUND: Despite the use of angular stable implants for proximal humeral fractures a lot of problems remain unsolved such as cutting out of screws, secondary displacement of the greater tubercle and the aim to minimize operative morbidity. This study analyses whether a plate using the DHS …
