Interaction Between Vortex‐Induced Vibrations and Base Vibrations in Piezoelectric Harvesters
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT In the present era, powering sensors using green energy is a significant challenge. One promising solution for the power supply of small sensors relies on piezoelectric energy harvesters excited by vortex‐induced vibrations (VIVs) generated by wind.

Researches on Axial Flow Turbines (1st Report)
Bulletin of JSME, 1959 It is necessary to carry out actual turbine testings to know the characteristics of turbine blades in the moving state. Then, we research the dynamical characteristics of turbine blades with two testing turbines ; one is an impulse turbine of partial admission and the other is a specially designed low pressure turbine of double rotation type.

Development of Vertical Wind Turbine Blades Using 4D Printing of Composites
Polymer Composites, EarlyView.Vertical axis wind turbine: White blade: Commercial. Black blade: Composite. ABSTRACT This paper presents the procedure to make vertical wind turbine blades using the technique of 4D printing of composites (4DPC). The blades are made using carbon/epoxy composite materials with a fiber volume fraction of about 60%.

Quarterly Journal of the Royal Meteorological Society, EarlyView.This study develops a method to identify the source areas of precipitation events, as illustrated for the western part of the Netherlands. Radar‐based precipitation data are traced back to their source areas and machine‐learning techniques are used to identify hypothesized causes: urban heat, surface roughness, and air pollution. We find that urban and
