Structure of a parallel hybrid electric vehicle. The grey squares represent differential gears. Parallel hybrid systems have both an internal combustion engine and an electric motor that can both individually drive the car or both coupled up jointly giving drive. This is the most common hybrid system as of 2016.
A hybrid system is a dynamical system that exhibits both continuous and discrete dynamic behavior – a system that can both flow (described by a differential equation) and jump (described by a state machine, automaton, or a difference equation). [ 1 ] Often, the term "hybrid dynamical system" is used instead of "hybrid system", to distinguish ...
Instead of using a single processor to solve the initial value problem (as is done with classical time-stepping methods), Parareal makes use of processors. The aim to is to use processors to solve smaller initial value problems (one on each time slice) in parallel. For example, in a MPI based code, would be the number of processes, while in an ...
Parallel Hybrids. Of 25 million gasoline-electric hybrids on the world's roads, most are Toyotas—and most of those use the company's classic two-motor power-split parallel hybrid system. It used ...
Figure 1: Example two-port network with symbol definitions. Notice the port condition is satisfied: the same current flows into each port as leaves that port.. In electronics, a two-port network (a kind of four-terminal network or quadripole) is an electrical network (i.e. a circuit) or device with two pairs of terminals to connect to external circuits.
The first SPIKE partitioning and algorithm was presented in and was designed as the means to improve the stability properties of a parallel Givens rotations-based solver for tridiagonal systems. A version of the algorithm, termed g-Spike, that is based on serial Givens rotations applied independently on each block was designed for the NVIDIA ...
Quantum algorithms are usually described, in the commonly used circuit model of quantum computation, by a quantum circuit that acts on some input qubits and terminates with a measurement. A quantum circuit consists of simple quantum gates, each of which acts on some finite number of qubits. Quantum algorithms may also be stated in other models ...
MUMPS (MU ltifrontal M assively P arallel sparse direct S olver) is a software application for the solution of large sparse systems of linear algebraic equations on distributed memory parallel computers. It was developed in European project PARASOL (1996–1999) by CERFACS, IRIT - ENSEEIHT and RAL. The software implements the multifrontal ...
