In physics, work is what force does.
When a force is applied on an object for a certain amount of time, the work done by the force is defined as the magnitude of the force (its strength) times the displacement of the object from its initial position to its current position (shortest distance between point A and B), tim... |

Counting hypergraphs with large girth
Sam Spiro, Jacques Verstraëte
Morris and Saxton used the method of containers to bound the number of ‐vertex graphs with edges containing no ‐cycles, and hence graphs of girth more than . We consider a generalization to ‐uniform hypergraphs. T... |
The keyboard we discuss here is a TeckNet mechanical keyboard, X705 UK layout. I believe it is called a 65% keyboard, although it doesn't actually say. I personally never use the numpad and have no purpose for it on my desk, so I can save some space and money by simply having a keyboard without it. From memory it cost ... |

Dot product - MATLAB dot - MathWorks América Latina
Dot Product of Complex Vectors
Dot Product of Multidimensional Arrays
C = dot(A,B,dim)
C = dot(A,B) returns the scalar dot product of A and B.
If A and B are vectors, then they must have the same length.
If A and B are matrices or multidimensional arrays, then they mu... |
