The economic emission dispatch (EED) is a highly constrained nonlinear multiobjective optimization problem with convex (or nonconvex) solution space. These characteristics and constraints make the EED difficult to solve. Several approaches for have been proposed, such as deterministic techniques, stochastic or combination of both. This work presents use an algebraic (deterministic) technique, numerical polynomial homotopy continuation (NPHC) method, solve problem. A comparison sequential...

The current stage of quantum computing technology, called noisy intermediate-scale (NISQ) is characterized by large errors that prohibit it from being used for real applications. In these devices, decoherence, one the main sources error, generally modeled Markovian master equations such as Lindblad equation. this work, decoherence phenomena are addressed perspective steepest-entropy-ascent thermodynamics (SEAQT) framework in which noise part seen internal to system. well describe changes...

As has been shown elsewhere, a reasonable model of the loss entanglement or correlation that occurs in quantum computations is one which assumes they can effectively be predicted by framework presupposes presence irreversibilities internal to system.

The equation of motion steepest-entropy-ascent quantum thermodynamics (SEA-QT) was first postulated in the early 1980s with intent modeling non-linear dynamic behavior encountered nature, which unitary (linear) dynamics Schrödinger-von Neumann cannot. SEA-QT is used here to model decoherence phenomenon between two distinguishable and indivisible elementary constituents type spin–½ (e.g., bits or qubits). resulting set non-linear, first-order differential equations solved a...
