Electro-Harmonix MOD 11 $152 - It gives you access to all the modulation effects you can think of (two Tremolo algorhythms, Vibrato, Univibe, Through Zero Flanger, Modulated Pitch Shifter, and Filter Sweep) and also to some sonic "treats" in the shape of hidden parameters accessible through...
Another longer term approach, desirable for quantum-dot (QD) lasers, is to directly grow epitaxial gain material on the Si wafer108. Due to its lower linewidth enhancement factor,αH, QD lasers enable lower linewidth and reduced sensitivity to reflections94,109. They also have lower threshold c...
5d. Smaller photon numbers and lower undersampling ratio are possible by using more advanced imaging processing algorithms, but at the price of longer image processing time16,17. Fig. 5: MIR single-photon compressive imaging. a, b Reconstructed images under the sub-Nyquist sampling with a ...
I do not really understand why i can’t use an absorption material to lower the sound from inside the cabinet or can i? If a big part of the the sound energy will be changed in to heat energy in the absorption material, would this not lower the the sound outside the cabinet? Or ...
It is also evident that, at constant displacement, longer vessels are more comfortable than smaller ones of similar configuration because the relative wavelength becomes shorter [15]. For this reason, the influence of principal dimensions on ship response in waves focuses on the effect of ...
Once the battery can no longer sustain the current setting, the light drops to 5 lumens, so you still have something to see. Until we got the hang of operating the 750, clicking through its red and white floods, spot, strobe, and combined flood and spot via the single button on the ...
The lower the molecular weight of a thermodynamic inhibitor, the better the hydrate suppression performance. For example, in glycols MEG has better performance characteristics than diethylene glycol DEG, and methanol MeOH will outperform ethanol EtOH. This tip of the month provides insight into the ...
A comprehensive understanding of controlling the iridescence of cellulose films by manipulating the alignment and helical pitch of cellulose nanocrystals (CNCs) is required to advance cellulose photonics and its optoelectronic applications. Aqueous suspe
