Active Control of Large Telescopes, two beneficial effects: . gathering more light (more photons), which allows the observation of fainter objects, and . increasing the limit resolution of the telescope, which allows to distinguish finer details.

Semi-active Control,dent of any external power supply. Another critical issue with active control is the stability robustness with respect to sensor failure; this problem is especially difficult when centralized controllers are used.

组成

Collocated versus Non-collocated Control,rturbations. This is because the root locus plot keeps the same general shape, and remains entirely within the left half plane when the system parameters are changed from their nominal values. Such a control system is said to be . with respect to stability. The use of collocated actuator/sensor pairs is recommended whenever it is possible.

Triglyceride

Optics in Nanotechnologyer, especially and most interestingly in metal and semiconductors. In a nanometal medium, light can be guided, confined, and focused far beyond what conventional dielectric technology offers. Whereas in a dielectric medium, focusing is wavelength-limited (diffraction-limited) to ~300 nm at best, in

Conducive

Performing Content-Based Retrieval of Humans Using Gait Biometrics,lution, the human walk (their gait) can be determined automatically, and more readily than other features such as the face. Effective analysis of such data relies on retrieval of video data which has been enriched using semantic annotations. A manual annotation process is time-consuming and prone to

Windenergieanlagen,rdern eine Reduzierung der immer noch größer werdenden umweltschädigenden Emissionen. Bei der Elektrizitätserzeugung lassen sich insbesondere durch die Nutzung erneuerbarer Energien nennenswerte Entlastungen erreichen. Dabei kommen — neben der weltweit genutzten Wasserkraft — den immensen Potentiale

A Simple Energy Pump for the Surface Quasi-geostrophic Equation,me exceeds .. The idea of the construction is quasilinear. We use a small perturbation of a stable shear flow. The shear flow can be shown to create small scales in the perturbation part of the flow. The control is lost once the nonlinear effects become too large.

The Business of Time,r dials recording and measuring three other types of time. As shown in Figure 2.1, these clocks relate to the body, life and the mind. The first governs our awareness of time, the second our sense of it, the third our experience of it.
