Abstract: A method of controlling the cooling of servers in a data center including a plurality of server racks each including a plurality of servers, the cooling being provided by aisle cooling units via a cold isle and by server fans, wherein the method includes: obtaining temperature measurements from temperature sensors in the data center, performing an optimization of the total power consumption of the aisle cooling units and of the servers based on the temperature measurements, with constraints on a cold aisle temperature and on an air flow level of the aisle cooling units, and controlling the aisle cooling units based on the optimization.

Abstract: A method of controlling a propulsion system of a marine vehicle by a controller, which forms data on a pitch angle (?(?)) of at least one foil based on an angularly variable wake field (W(?)) affecting the at least one foil and an angle (?) of a rotation of the foil wheel. An actuator arrangement that receives the data from the controller sets the at least one foil at the pitch angle (?(?)) based on the data.

Abstract: An apparatus, method and computer program for controlling propulsion of marine vessel. The propulsion is implemented by a foil wheel propulsion system. The method includes: receiving a wheel operation status from a wheel drive; receiving a plurality of foil operation statuses from a plurality of foil drives; receiving a command from a vessel control system; generating wheel control data for the wheel drive to control a foil pitch function of the foil wheel propulsion system based on the command in view of the wheel operation status; and generating foil control data for the plurality of the foil drives to further control the foil pitch function of the foil wheel propulsion system based on the command in view of the wheel operation status and the plurality of foil operation statuses, wherein a reference torque of the foil control data for each foil drive is generated using a foil feedforward model.

Abstract: A method for inspecting a solar panel of a solar power station is performed in a controller for an unmanned aerial vehicle, UAV, and includes the steps of: receiving an inspection request for a subset of the solar panels navigating, in a first stage, using radio signals, the UAV to an initial location in a vicinity of a particular solar panel of the subset of solar panels; positioning, in a second stage, the UAV using at least one near field sensor of the UAV; and capturing, using the infrared camera, an image of the particular solar panel.
