Anthropic principle - Wikipedia

The ,anthropic principle, is often criticized for lacking falsifiability and therefore critics of the ,anthropic principle, may point out that the ,anthropic principle, is a non-scientific concept, even though the weak ,anthropic principle,, "conditions that are observed in the universe must allow the observer to exist", is "easy" to support in mathematics and philosophy, i.e. it is a tautology or truism.

Basic principle of ct and ct generations
Basic principle of ct and ct generations

Basics ,Principle, The basic ,principle, behind CT is that the internal structure of an object can be reconstructed from multiple projections of the object. The ray projections are formed by scanning a thin cross section of the body with a narrow x-ray beam and measuring the transmitted ,radiation, with a sensitive ,radiation, detector.

X-Ray Production
X-Ray Production

X-,radiation, is created by taking energy from electrons and converting it into photons with appropriate energies. This energy conversion takes place within the x-ray tube. The quantity (exposure) and quality (spectrum) of the x-,radiation, produced can be controlled by adjusting the electrical quantities ( KV , MA ) and exposure time, S , applied to the tube.

A Topological Design Tool for the Synthesis of Antenna ...

Patch antennas are among the most popular radiating elements, yet their quasi-2-D structure reduces the degrees of freedom available to tailor their ,radiation, pattern. To overcome this limitation, a possible solution consists in etching on a grounded substrate two concentric radiating elements and combining two modes (one for each element) with proper amplitude/phase relations. Although this ...
