  1. 2 days ago · The Laplace transform is used frequently in engineering and physics; the output of a linear time-invariant system can be calculated by convolving its unit impulse response with the input signal. Performing this calculation in Laplace space turns the convolution into a multiplication; the latter being easier to solve because of its algebraic form.

    3 days ago · The brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making ...

  3. 4 days ago · In mathematical physics and mathematics, the Pauli matrices are a set of three 2 × 2 complex matrices that are Hermitian, involutory and unitary. Usually indicated by the Greek letter sigma ( σ ), they are occasionally denoted by tau ( τ ) when used in connection with isospin symmetries.

  4. 3 days ago · The addition of two signals results in a signal that has their summed amplitudes at every time step. So, summing two signals, \ (X_0\) and \ (X_1\) results in \ (X_2\). That means at every possible time step, \ (X_2\) has a signal value that is the sum of the values of \ (X_0\) and \ (X_1\) at that time step.

  5. 2 days ago · Description. This monograph is centered on quantitative analysis of nerve-cell behavior. The work is foundational, with many higher order problems still remaining, especially in connection with neural networks. Thoroughly addressed topics include stochastic problems in neurobiology, and the treatment of the theory of related Markov processes.

  6. The beta function (also known as Euler's integral of the first kind) is important in calculus and analysis due to its close connection to the gamma function, which is itself a generalization of the factorial function. Many complex integrals can be reduced to expressions involving the beta function. Definition. Symmetry.

  7. 6 days ago · If x ( t) is a solution of Eq. (1), it follows from the chain rule that. ˙V(x) = ∂(V ∘ x) ∂t (t). Theorem 1: The function V is a Liapunov function for the system ˙x = − ∇ ⋅ V(x). Moreover, ˙V(x) = 0 if and only if x is an equilibrium point. The study of gradient systems (1) is particularly simple due to the formula.
