A control system for a wind turbine comprises: a sensor arrangement for capturing measures related to the turbine operation and fatigue accumulation; an upper level controller, which, on the basis of a statistical treatment of said measures, calculates optimized control settings at discrete points of time; a measurement module which processes said measures into instantaneous values; and a lower level controller that receives said control settings and said instantaneous values and calculates instantaneous optimal commands to control turbine actuators. The lower level controller comprises a continuous-time damage model which calculates the rate at which damage is accumulated at any time, and an optimal controller which controls operational states of the turbine, either by directly giving feedback of the instantaneous values to the actuators, or by generating a turbine performance objective function which is continuously optimized by repeatedly solving a receding horizon optimization problem.

A method for minimizing VMWARE™ snapshot lifetime, by reading data from a storage snapshot created on the VM storage side. The reading is performed by mounting the storage snapshot as a new datastore on an ESX(I) host and accessing the host using a standard VMWARE™ VDDK (vStorage API) method. A pre-configured source ESX(I) host contains a VM that needs to be backed up. A SAN storage connected to the ESX(I) host over iSCSI or FibreChannel or NFS protocols is used. The backup agent, which contains the proprietary code, is installed on a physical or a virtual machine connected to an ESX(I) host. This backup agent maintains the operations with the ESX(I) host and the SAN storage and coordinates the VM virtual disks data read and write operations. The backup agent contains the executable code, which provides compatibility with SAN storage and ESX(I) host.

A projection display uses a light modulating device to modulate, in accordance with image data, light radiated from a light source, project the modulated light onto a screen, and display an image. The projection display separates a unit of time configuring the image data into an effective light time when the light modulating device can express the light as an image on the screen and an ineffective light time when the light modulating device cannot express the light as an image on the screen. The projection display increases the power supplied to the light source during the effective light time over the power supplied to the light source during the ineffective light time.
