Modeling process dynamics in membrane-electrolyte-assemblies of chloralkali electrolyzers considering steric and hydration effects
… thermodynamic theory is proposed to model the process dynamic in Membrane-Electrolyte-Assembly (MEA). The model describes the electrolyte in the MEA as a hydrated multicomponent mixture, that consists of five main components, viz. Na⁺, Cl⁻, OH⁻, and water. In general, the formulated model …

Feasibility of waste-derived hydroxyapatite mixed with ultra high molecular weight polyethylene composites for fused deposition modeling process
… UHMWPE composites for Fused Deposition Modeling (FDM) process was investigated. Compared to the commercial HAp, derived from natural resources such as corals, fish bone and eggshells have been converted into HAp and show the similarity with the commercial HAp. Ca/P ratio was so important …

Risk-Based Framework for Focused Assessment of System Dynamics Models
… often not being well received in traditional modeling application areas or within the broader research community. With a foundation in taxonomy classification techniques, this research developed a modeling process risk-based framework focused on the objectives of the system dynamics …

Infrastructure for model management and model diagnosis
… the real world is a trial-and-error, iterative process where an ML developer builds tens to hundreds of workflows before arriving at one that meets some task-specific acceptance criteria. This iterative process of workflow building is laborious for several reasons including the large variety of …

Teachers' Conceptions of Mathematical Modeling
… in 2010 resulted in a new focus on mathematical modeling in United States curricula. Mathematical modeling represents a way of doing and understanding mathematics new to most teachers. The purpose of this study was to determine the conceptions and misconceptions held by teachers about …

5SGraph: A Modeling Tool for Digital Libraries
… libraries by non-experts requires a simplified modeling process and rapid generation of digital libraries. To enable rapid generation, digital libraries should be modeled with descriptive languages. A visual modeling tool would be helpful to non-experts so they may model a digital library …

Multivariate muti-level non-linear mixed-effect models and their application to the modeling of drug-concentration time curves
… details the necessary extensions to the basic modeling process that were required in order to accommodate multiple responses and multiple observation phases (pregnant and postpartum).

Exploring a New Conceptual Framework in Aviation Maintenance Incident Reporting Using Natural Language Processing
… analysis is accomplished using natural language processing to implement Latent Dirichlet Allocation in a topic modeling strategy. The topic modeling process distilled these reports into a set of topic word groups that reflect the prevalent themes within the corpus of documents, allowing for a …

Automation and Expert System Framework for Coupled Shell-Solid Finite Element Modeling of Complex Structures
… significant and is a major bottleneck in the FE modeling process. Additionally, there is a significant level of subjectivity involved in the decision-making about the multi-fidelity element topology due to a high dependence on the analyst's experience and expertise, which often leads to …

An Improved Algorithmic Approach to Iterative Floodway Modeling using HECRAS and GIS
… the hydraulic analysis also includes modeling a floodway in detailed floodplain study areas. Floodway modeling is an iterative process in which the 1% annual chance flood discharge is restricted within a floodway without exceeding a designated increase, called the surcharge (usually 1 …

Floodplain Risk Analysis Using Flood Probability and Annual Exceedance Probability Maps
… and model uncertainty inherent in the modeling process. The boundary at any recurrence interval from the AEP map gives a single, definite boundary that considers uncertainty. This research performed case studies using data from Leith Creek in North Carolina and the Virgin River in …

A model to understand population decline of the Devil's Hole pupfish (Cyprinodon diabolis) and support habitat management decisions
… to reverse or stop the deCline The model and modeling process was used to identify critical gaps in existing data. Tests simulating pore space manipulation, algae removal and addition of refugia fish resulted in long-term population growth but not quick, short-term changes.

A multi-level explanation of the process of innovation
This research models the process of innovation with an iterative multi-method model made up of a system dynamic (SD) model and an agent-based model (ABM). This method is a tested and validated modeling process for the study of dynamic processes that take place during disequilibrium (Ross and …

Modeling Software Product Lines Using Feature Diagrams
… software products in a domain are built. Feature modeling is a process that enables engineers to identify these core assets, in particular the com(e.g., shared) and variable features of products. The focus of this thesis is to give an overview of the feature modeling process by introducing feature …
