The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as the North Cascades, and the notable volcanoes known as the High Cascades. The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as the Cascade Mountains. The latter term is also sometimes used by Washington residents to refer to the Washington section of the Cascades in addition to North Cascades, the more usual U.S. term, as in North Cascades National Park. The highest peak in the range is Mount Rainier in Washington at 14,411 feet (4,392 m).
The Cascades are part of the Pacific Ocean's Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. All of the eruptions in the contiguous United States over the last 200 years have been from Cascade volcanoes. The two most recent were Lassen Peak from 1914 to 1921 and a major eruption of Mount St. Helens in 1980. Minor eruptions of Mount St. Helens have also occurred since, most recently from 2004 to 2008. The Cascade Range is a part of the American Cordillera, a nearly continuous chain of mountain ranges (cordillera) that form the western "backbone" of North America, Central America, and South America.

Here is a common CE-CC cascade amplifier-
Here, the output of the emitter amplifier is directly connected to Q2, without any coupling capacitor or any voltage divider bias. This may harm the base-emitter junction of Q2 in case of unwanted output voltage from Q1 collector. But in that case, the...
In my limited understanding of the quantum measurement problem, I am imagining the whole thing as corresponding to a kind of "weighting down" by a cascade of entaglement.
Here is my very simple understanding of the quantum measurement problem: A waveform (Schrödinger equation) describes the...
Summary:: What is the structure and how are minibands and minigaps in QC Lasers implemented
I have a question regarding the miniband and minigaps that are displayed widely in diagrams about the functioning of Quantum Cascade Lasers. How are this mini-gaps established...
Hello I am struggling to understand the concept of Quantum cascade lasers. I am doing research on a 20 period In0.33Ga0.67As (3.1 nm)/Al0.90In0.10As (7.2 nm) superlattice and would like to fully understand how a quantum cascade laser works. I also have not taken quantum mechanics yet so I...
Above is a sketch of the circuit, a two stage symmetrical attenuator consisting of two symmetrical T attenuator pads connected in cascade, with the values that I have worked out for the resistors.
The reduction is 15dB in the first stage, and 8dB in...
A calorimeter is made from layers of lead (1.75mm thick) alternated with layers of scintillator. The radiation length ##X_0## of lead is ##0.64cm##.
In an EM shower the number of particles doubles and the energy of each particle halves per radiation length travelled. The...
Since we often get comments on US Volcanoes, particularly those in California, Oregon and Washington State, I thought it would be worthwhile to have a separate Cascade Volcano thread.
USGS has a Cascade Volcano Observatory.
There is also a site on...
As far as I know first entanglement experiment used polarization entangled photons from atomic cascade. As I understand atomic cascade produces entangled photons from two electrons that emit photons by falling from the same orbital to the same lower orbital (so they have the same spin).
is this thing accurate? It uses methylene chloride as first refrigerant, then ethene, and then oxygen, and gets to liquefy air...down to 70kelvins
after researching the very small info on the net about cascade...
How are these pictures taken of the electron wave function without the wave function collapsing?
Does this mean that electron wave functions are real waves after all?
Wikipedia Quantum cascade laser will give you the discription
Why for quantum cascade lasers used only intersubband transitions in the conduction band. Although in a heterostructure there are also quantized levels in the valence band, which I think also can be used for lasing?
I am taking a course in Microwave Engineering and we were given the following problem to solve

I've been trying to understand a simulation for a collision cascade. The PhD that produced this code says that he is modelling a 10keV collision in Fe. From this he says that his PKA velocity is 2620.579 ang/ps or 262057.9 m/s and I'm wondering how did he get this?
I've assumed that the...

Got cascade voltage transformer made from two completely identical units.
On secondary winding, load takes I2=1A
Number of compensation and secondary windings is equal.
I need to find current trough compensation winding Ic .
θ1 = θ2
--> θ1 = I1N1 + IcNc - I2N2
--> θ2 = I1N1 - IcNc
I need help on how to cascade two or three Jfet transistor and the calculation of the values to have a good amount of gain. The cascade also should help in providing good linearity, have less distortion and should stable good stability.Thanks, good help will really be appreciated by me.

I just stumbled upon these forums and joined with the hopes that I could seek some help from some more experienced people. Thank you for your time.
i want to design cascade buck converter,but I'm kinda confuse about the controller that i'll use for the converter...there are 2 options, i make the controller independent from 1 converter to another, or i just make the controller dependent, it means that i have only 1 controller for all...
