Sonar micro-Doppler effect induced by ship oscillatory motion in waves: Phenomenon, model, and experimentation [PDF]
JASA Express LettersTraditional research attributes the modulated sidebands of ship radiation line-spectrum signals to reflections off rough ocean surfaces, but the Doppler effect caused by vessel motion may also contribute.

Shock and Vibration, 2018 Wave loads estimation and structural strength evaluation are the fundamental work at the ship design stage. The hydroelastic responses and slamming strength issues are also concerned especially for large-scale high-speed ships sailing in harsh waves.

, 2016 Ship added resistance is a steady force of the second order which depends on the ship motions and wave diffraction in short waves. To predict the impact of liquid motions inside the ship hull, a flooded tank in the midship area is generated and the ship ...

Archaeological Prospection, EarlyView.ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

NUMERICAL SIMULATIONS OF ADDED RESISTANCE IN REGULAR HEAD WAVES ON A CONTAINER SHIP
Brodogradnja, 2019 Although shipping was not included in the final text of the Paris Agreement in 2015, IMO (International Maritime Organization) adopted the EEDI (Energy Efficiency Design Index) and the EEOI (Energy Efficiency Operational Indicator) to control climate ...

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection
Archaeological Prospection, EarlyView.ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

Seakeeping performances of an AHTS ship
Annals of "Dunărea de Jos" University of Galaţi: Fascicle XI Shipbuilding, 2016 The importance of the evaluations of the response amplitude operators as well as of the accelerations in several points of interest on board of ship is directly linked to the index of operation of a floating structure. The higher the sea state to operate,

Dissecting the dissection laboratory: Elements for designing a human anatomy laboratory
Anatomical Sciences Education, EarlyView.Abstract The human anatomy dissection laboratory is a critical component of anatomical and medical education. Development, maintenance, and stocking of these laboratory spaces have unique demands, with all of the challenges in running a laboratory with Biosafety Laboratory Level 2 (BSL‐2) classification, housing a large volume of tissues saturated with
