Application of Fuzzy Logic Controller to Enhance The Semi-SWATH Performance in Following Seas

Jurnal Teknologi, 2014
Semi-SWATH ship has a different characteristics compared to the common ship hull. The ship has a tendency to suffer bow-dive due to low restoring force at bow when running in following seas. In some conditions, the foredeck found to be immersed under the rear of wave.

Contribution of a Wide-Swath Altimeter in a Shelf Seas Assimilation System: Impact of the Satellite Roll Errors [PDF]

Journal of Atmospheric and Oceanic Technology, 2008
Abstract The authors investigate the potential qualitative improvement brought by wide-swath, interferometry-based ocean altimetry measurements with respect to classical nadir altimeters in a coastal/shelf data assimilation system. In addition, particular attention is paid to roll errors, which could significantly reduce the expected ...

Integrative Multi‐Omics Analysis Reveals a Mitochondrial–Immune Axis Associated With Neoadjuvant Chemotherapy Response in High‐Grade Serous Ovarian Cancer

Advanced Science, EarlyView.
Integrative multi‐omics analysis delineates a mitochondrial–immune axis governing neoadjuvant chemotherapy response in high‐grade serous ovarian cancer. Immune‐active tumors exhibit enhanced B‐cell infiltration and favorable sensitivity, whereas metabolically rewired tumors display oxidative phosphorylation dependency and resistance.
