At 7T, higher parallel imaging factors and closer echo spacings, made possible with the stronger and faster switched read gradients, permit encoding of higher spatial resolutions with minimized distortions and susceptibility artifacts, benefiting the SIR technique (see Fig. 3).
It discusses the requirements of a good WLAN radio receiver and WLAN radio transmitter, such as sensitivity to detect signals of widely varying magnitude in the presence of interferers, efficiency, ability to switch states, and minimized transmit distortion to avoid spurious radiation outside the intended channel and band.
The optimized design shows a beam quality of 1.20 corresponding to the minimized wavefront distortion with a peak-to-valley of 0.568 μm and root mean square of 0.115 μm even under high-power operation with a total pump power of 14 kW.
Then a fast calculation method, which can equally derive the minimized total harmonic distortion (THD) of total current, is proposed to release the calculation burden.
The gel helped the US probe to pass through the tumoral stenosis of rectum, minimized compression and distortion of the lesion, and improved visualization of the rectal wall and tumor.
For example, reference [7] considers a WSN with the orthogonal MAC and derives the optimal power allocation policies in a way that the total distortion is minimized subject to a sum power constraint at the sensors.
In the same context, it is worth mentioning that energy optimization with DFT-D is very sensitive even for small inaccuracies in a structure; as a result, even a minor error in the position of a H atom can lead to a major distortion in the energy-minimized crystal structure, and there is no relationship between the degree of the distortion and the severity of the error.
In particular, it is critical that distortions of clear images are minimized for safety.
Then, based on this model, an optimal bandwidth allocation strategy is developed in MANETs, with which, based on some network-specific constraints, the loss-induced distortion associated with a video source is minimized, using some cross-layer design techniques.
