In this paper, we consider the numerical methods for both the forward and backward problems of a time-space fractional diffusion equation. For the two-dimensional forward problem, we propose a finite difference method. The stability of the scheme and the corresponding Fast ...
forward-in-time methods for the advection terms, for example, the Crowley schemes (Tremback et al. 1987), and the forward–backward scheme for the fast modes had significant instabilities, even with filtering. Yet these and other forward-in-time schemes are attractive if a ...
They are public key based scheme (PKS), password based scheme (PWS) and billed value-based scheme (BVS). BVS can achieve forward and backward security and only relies on hash functions. Security analysis justifies that the proposed schemes, especially BVS, can attain the security goals with ...
This part can be understood as mapping the time series to a high-dimensional space, obtaining the enriched states, and finally collecting them in the ESM. 3.2.2 Decoder In the previous coding process, we know that the ESM collects states at time step \(0\sim T-1\). So we can select...

A decoupling reduction method is introduced via which a large class of linear FBSDEs with random or deterministic time-varying coefficients is proved to be solvable. On the other hand, by means of Four Step Scheme, a Riccati backward stochastic equation (BSDE, for short) for ( m × n ) ...
Unfortunately, this scheme is a first-order scheme since we used the forward Euler method for the time step. This means that we have to be careful about the size of the steps in time ht since large values quickly lead to numerical instability. The stepwidth in space hyz is significantly ...
