Planning a trip from Berlin to Hamburg, simulating air flows around a new passenger airplane, or friendships on Facebook – many computer applications model relationships between objects by graphs ...

These computations can be continuous, or analogue, in nature — the way eyes adjust to gradual changes in the light levels. They can also be digital, involving simple on or off processes, such as a ...

I woke up this morning, brushed my teeth and hurried downstairs. When I opened up the fridge and looked inside, I found myself in a bit of a grumble. Empty, again. Frustrated, I went out to the dining ...

Complex numbers are numbers that consist of two parts — a real number and an imaginary number. Complex numbers are the building blocks of more intricate math, such as algebra. They can be applied to ...

A rapid method for determining whether the real quadratic field $\mathscr{K} = \mathscr{Q}(\sqrt D)$ has class number one is described. The method makes use of the infrastructure idea of Shanks to ...

Perhaps nowhere is the truism 'structure defines function' more appropriate than for the brain. The architecture of different brain regions determines the kinds of computations that can be carried out ...

This is a preview. Log in through your library . Abstract Using the basis reduction algorithm of A. K. Lenstra, H. W. Lenstra, Jr. and L. Lovász [8] and an idea of Buchmann [4], we describe a method ...

Numbers provide literal or scalar storage and direct access. A number is also an immutable type, meaning that changing or updating its value results in a newly allocated object. This activity is, of ...
