Optimization of the Production of Rubber Compounds Using Mathematical Models

Advanced Engineering Materials, EarlyView.
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

Advanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Copper Nanocrystallization in Anodic Oxide Films of Ti–Cu‐Based Bulk Metallic Glass and Its Effect on the Corrosion Resistance and Cytocompatibility

Advanced Engineering Materials, EarlyView.
Viktoriia Shtefan, Thorgund Nemec, Ute Hempel, Annett Gebert and coworkers demonstrate that anodic treatment of Ti–Cu‐based metallic glass in a nontoxic pyrophosphate electrolyte forms a protective bilayered Ti/Zr‐oxide film enriched with Cu nanocrystals.

Toward Knowledge‐Based Workflows: A Semantic Approach to Atomistic Simulations for Mechanical and Thermodynamic Properties

Advanced Engineering Materials, EarlyView.
Knowledge‐based atomistic workflows are presented for mechanical and thermodynamic properties. By coupling modular simulations with ontology‐aligned metadata and provenance, Fe case studies on elastic behavior, defects, thermal properties, and Hall–Petch strengthening reveal how FAIR, queryable, and reusable simulation data can be generated. Mechanical

Alternative Metrics for Assessing Knowledge Assets [PDF]

Journal of Information & Knowledge Management, 2013
This paper analyzes two different approaches to assessing the knowledge assets of multiple firms in a given industry. Typically, in evaluating knowledge management (KM) results by measuring intellectual capital (IC), studies in the field have looked specifically at individual firms or a small cluster of organisations.

ASSET queries

ACM SIGMOD Record, 2009
Today's complex world requires state-of-the-art data analysis over truly massive data sets. These data sets can be stored persistently in databases or flat files, or can be generated in realtime in a continuous manner. An associated set is a collection of data sets, annotated by the values of a domain D.

Alternative Asset Classes: An Alternative to What?

2011
Appreciate what constitutes an alternative asset class and the wide and disparate nature of the alternatives universe. Understand the key characteristics and nuances of hedge funds, private equity, commodities and foreign exchange and their potential risks, returns and diversification benefits. Appreciate the additional governance burden that

Portfolios of Alternative Assets

The Journal of Investing, 1999
In recent years, interest in “alternative assets” has increased tremendously, driven by the eternal search for superior risk-adjusted returns. Hedge “funds of funds” and principal-protected versions of hedge funds in particular have made major inroads into portfolios of high net worth individuals and institutions with relatively liberal investment ...

On the Performance of Timberland as an Alternative Asset

Journal of Forest Economics, 2022
The financial performance of timberland as an alternative asset is assessed by the intertemporal capital asset pricing model and Fama-MecBeth two-step regression method. In the analysis, alternative assets include emerging markets, hedge funds, private equity, venture capital, commodities, real estate, farmland and timberland; conventional assets ...
