Phenomenological Fluids from Interacting Tachyonic Scalar Fields
In this paper we are interested to consider mathematical ways to obtain
different phenomenological fluids from two-component Tachyonic scalar fields.
We consider interaction between components and investigate problem numerically.
Statefinder diagnostics and validity of the generalized second law of
thermodynamics performed and checked. We suppose that our Universe bounded by
Hubble horizon.Comment: 12 page
Robust Model Predictive Control for Signal Temporal Logic Synthesis
Most automated systems operate in uncertain or adversarial conditions, and have to be capable of reliably reacting to changes in the environment. The focus of this paper is on automatically synthesizing reactive controllers for cyber-physical systems subject to signal temporal logic (STL) specifications. We build on recent work that encodes STL specifications as mixed integer linear constraints on the variables of a discrete-time model of the system and environment dynamics. To obtain a reactive controller, we present solutions to the worst-case model predictive control (MPC) problem using a suite of mixed integer linear programming techniques. We demonstrate the comparative effectiveness of several existing worst-case MPC techniques, when applied to the problem of control subject to temporal logic specifications; our empirical results emphasize the need to develop specialized solutions for this domain
