TORSIONAL VIBRATION STRESS AND FATIGUE STRENGTH ANALYSIS OF MARINE PROPULSION SHAFTING SYSTEM BASED ON ENGINE OPERATION PATTERNS

Torsional Vibration Stress and Fatigue Strength Analysis of Marine Propulsion Shafting System Based on Engine Operation Patterns

Modern merchant ships use marine propulsion systems equipped with an ultra-long-stroke diesel engine that directly drives a large slow-turning propeller.Such systems use fewer cylinders and generate greater power at slower shaft speeds, which affords improved propulsion performance as well as low repair and maintenance costs.However, this also resu

Deep Electrical Resistivity Tomography for the Hydrogeological Setting of Muro Lucano Mounts Aquifer (Basilicata, Southern Italy)

The proposed work concerns the application of a deep geoelectrical survey to a carbonate aquifer in order to define the best location for exploitation well drilling for increasing water supply.However, an optimal characterization of a groundwater resource is the necessary condition to reach the indicated aim.Therefore, the geoelectrical investigati

A colored KNT neutrino model

We propose a radiative seesaw model at the three-loop level, in which quarks, leptons, leptoquark bosons, and a Majorana fermion of dark matter candidate are involved in the neutrino loop.Analyzing canon imageclass mf227dw neutrino oscillation data including all possible constraints such as flavor changing neutral currents, lepton flavor violations
