It has recently been shown that the Einstein equation can be derived by demanding a non-equilibrium entropy balance law dS = δQ/T+ diS hold for all local acceleration horizons through each point in spacetime. The entropy change dS is proportional to the change in horizon area while δQ and T are the energy flux across the horizon and Unruh temperature seen by an accelerating observer just inside...

In this paper, we compare the force expressions in both comoving synchronous and Ellis coordinate systems Friedman-Robertson-Walker spacetime order to understand how transformation affects inertial forces. We also studied negative energy problem system. The Penrose process is possible outside apparent horizon due fact that line element has off-diagonal term. However, only movement towards infin...

Much of the literature on capital inflow sudden stops uses models with short term debt only but draws conclusions about the role of debt maturities in crises. In this paper short and long term debt are introduced in an infinite horizon, representative agent model that is consistent with modern open economy macroeconomic models of the type presented in Obstfeld and Rogoff (1996). Phase diagrams ...

In This paper we investigate the design of controllers, for discrete-time Markovian jump linear systems, that achieve optimal reference tracking in the presence of preview. In particular, given a reference sequence, we obtain the optimal control law for the fully observed case, while the output feedback case is also briefly discussed. We provide the optimal control law for the infinite and fini...

Support Vector Regression (SVR) has been widely applied in time series forecasting. Considering long term predictions, iterative predictions perform many one-step-ahead predictions until the desired horizon is achieved. This process accumulates the error from previous predictions and may affect the quality of forecasts. In order to improve long term iterative predictions a hybrid multiple Autor...

In the context of a Brownian filtration and with a fixed finite time horizon, we will provide a representation of the penalty term of general dynamic concave utilities (hence of dynamic convex risk measures) by applying the theory of g-expectations.

We consider generic static spacetimes with Killing horizons and study properties of curvature tensors in the horizon limit. It is determined that the Weyl, Ricci, Riemann and Einstein tensors are algebraically special and mutually aligned on the horizon. It is also pointed out that results obtained in the tetrad adjusted to a static observer in general differ from those obtained in a free-falli...
