Solving Finite-Horizon Discounted Non-Stationary MDPS

open access: yesFolia Oeconomica Stetinensia, 2023
Markov Decision Processes (MDPs) are a powerful framework for modeling many real-world problems with finite-horizons that maximize the reward given a sequence of actions.

Development of a tight-binding potential for bcc-Zr. Application to the study of vibrational properties [PDF]

open access: yes, 2001
We present a tight-binding potential based on the moment expansion of the density of states, which includes up to the fifth moment. The potential is fitted to bcc and hcp Zr and it is applied to the computation of vibrational properties of bcc-Zr.

Elastic Properties and Magnetic Phase Diagrams of Dense Kondo Compound Ce0.75La0.25B6

open access: yes, 2006
We have investigated the elastic properties of the cubic dense Kondo compound Ce0.75La0.25B6 by means of ultrasonic measurements. We have obtained magnetic fields vs temperatures (H-T) phase diagrams under magnetic fields along the crystallographic [001],

Use of Constraints in the Hierarchical Aggregation Procedure Intramax

open access: yesBusiness Systems Research, 2016
Background: Intramax is a hierarchical aggregation procedure for dealing with the multi-level specification problem and with the association issue of data set reduction, but it was used as a functional regionalization procedure many times in the past.

A hybrid model for distribution center location selection

open access: yesAsian Journal of Shipping and Logistics, 2022
This research aims to propose an integrated MCDM model to support the distribution center location selection. The integrated approach of ANP and TOPSIS was employed to address the distribution center selection problem.

The Influence of Annealing on the Sb Layer in the Synthesis of [001]‐Oriented Sb2Se3 Film for Photoelectrochemical Hydrogen Gas Generation

open access: yesAdvanced Functional Materials, EarlyView.
[001]‐oriented Sb2Se3 film with improved crystallinity and adjusted composition is achieved via a new thermal treatment approach consisting of preliminary annealing of the Sb layer before its selenization. The findings of this work demonstrate enhanced charge carriers' transportation, a stable performance, and an improvement of H2 generation from ...
