Solving Sparse Differential Riccati Equations on Hybrid CPU-GPU Platformsccati equations (DRE) is a key operation for the computation of the optimal control in the finite-time horizon case. In this work, we focus on large-scale problems governed by partial differential equations (PDEs) where, in order to apply a feedback control strategy, it is necessary to solve a large

A Hybrid CPU-GPU Scatter Search for Large-Sized Generalized Assignment Problems has several industrial applications and often appears as substructure of other combinatorial optimization problems. By harnessing the massive computational power of Graphics Processing Units in a Scatter Search metaheuristic framework, we propose a method that efficiently generates a solution pool

Vector Field Second Order Derivative Approximation and Geometrical Characteristicsthe vector field. We will show how to approximate the vector field with second order derivatives, i.e. Hessian and Jacobian matrices. This approximation gives us much more detailed description of the vector field. Moreover, we will show the similarity of this approximation with conic section formula

Exhaustive Analysis for the Effects of a Feedback Regulation on the Bi-Stability in Cellular Signalied intensively since the malfunction of the regulation is thought to be one of the substantial causes of cancer formation. However, it is rather difficult to develop the theoretical framework for investigation of the regulatory mechanisms due to their complexity and nonlinearity. In this study, more

Q-matrix Extraction from Real Response Data Using Nonnegative Matrix Factorizations decomposition method which extracts latent information from data in such a way that it can be easily interpreted by humans. Particularly, the NMF of a score matrix can automatically generate the so called .-matrix. In an e-learning scenario, the .-matrix describes the abilities to be acquired by st
