Multiple Definition and 1000 Threads

A multiple-unit train or simply multiple unit (MU) is a self-propelled train composed of one or more carriages joined together, which when coupled to another multiple unit can be controlled by a single driver, with multiple-unit train control.
Although multiple units consist of several carriages, single self-propelled carriages - also called railcars, rail motor coaches or railbuses - are in fact multiple-units when two or more of them are working connected through multiple-unit train control (regardless if passengers can walk between the units or not).
The term multiple unit does not denote locomotives using multiple-unit train control.

    A Differential of Multiple Linear Regression

    Say you have a log-level regression as follows: $$\log Y = \beta_0 + \beta_1 X_1 + \beta_1 X_2 + \ldots + \beta_n X_n$$ We're trying come up with a meaningful interpretation for changes Y due to a change in some Xk. If we take the partial derivative with respect to Xk. we end up with...

    Is there such a thing as multiple simulation?

    We know that a computer can simulate phenomena. Is it possible to simulate the same phenomena partially on different computers simultaneously? For example, Computer 1 simulates the front of a statue. Computer 2 simulates the back of a statue. Computer 3 simulates the birds eye view of a statue...

    Confusion with multiple impulses

    Suppose I have a body of mass M kept on a horizontal smooth surface. I strike that particle with some force ,providing an impulse J_1. The applied force is in vertically downward direction. Suppose that the body deforms in this process and it doesn't rebound. What I want to know is, whether the...

    Multiple rotors on a wind turbine

    Could multiple, smaller rotors on a wind turbine (on the same shaft) be more effective than a single, larger rotor? Why do most wind turbines have only one big rotor? I was thinking about doing a science fair project on this topic, but I have been unable to find a conclusive answer to this...

    AC Mains Distribution energized from multiple AC voltage sources

    Even though its possible to keep a bus charged from more than one AC voltage sources, what can be the consequences of doing so?
