Hierarchical Policy Search via Return-Weighted Density Estimation

, 2017
Learning an optimal policy from a multi-modal reward function is a challenging problem in reinforcement learning (RL). Hierarchical RL (HRL) tackles this problem by learning a hierarchical policy, where multiple option policies are in charge of different

State of Charge Estimation of Thermal Storages for Distributed Generation Systems

Energy Procedia, 2014
AbstractThe aim of this work is the development of three different models to calculate the enthalpy content of a stratified water thermal storage tank from discrete temperature measurements. The difficulty related to enthalpy value evaluation comes from the discrete temperature measurement along the storage (often only 2 to 4 temperatures along the ...

Race and Household Income are Associated with Disease Outcomes in Pediatric Patients with ANCA‐associated Vasculitis Hospitalized in the United States

Arthritis Care &Research, Accepted Article.
Objectives Race and household income impact outcomes in patients with rheumatic conditions; however, their role in pediatric anti‐neutrophil cytoplasmic antibody (ANCA)‐associated vasculitis (AAV) remains poorly understood. We aimed to evaluate whether race/ethnicity and household income are associated with severe AAV disease and renal outcomes among ...

Thermoreflectance Detection of Point Defects Resulting from Focused Ion Beam Milling

Advanced Engineering Materials, EarlyView.
Focused ion beam (FIB) milling is a common tool for nanoscale material processing, however irradiation damage, redeposition, and contamination can occur. We use several characterization tools to show FIB‐induced effects beyond 1 mm from the milled area.

Electrochemical Evaluation of Compressed Selective Laser Melted AlSi7Mg and AlSi10Mg Alloys in Chloride Environment

Advanced Engineering Materials, EarlyView.
The corrosion performance of AlSi7Mg and AlSi10Mg alloys produced through selective laser melting (SLM) was examined under compressive stress in a chloride environment. Electrochemical analyses, including open‐circuit potential (OCP), potentiodynamic polarization (CPP), and electrochemical impedance spectroscopy (EIS), were complemented by scanning ...
