Specifications of model development
2016
Chapter 4 goes into detail with the specifications of the model and model validation. Why Partial Least Squares (PLS), a structural equation modelling approach, is chosen as the method for model testing is explained in section 4.1, while 4.2 describes the survey conducted to collect data for model testing. Section 4.3 goes into detail with the PLS approach, its theoretical background and its application to the research question, before section 4.4 outlines the necessary operationalisation of the constructs introduced in chapter 3.
Pengembangan Model PBL Terintegrasi Kognitif Moral Pada Mahasiswa PGSD UNIPA Surabaya
2021
The research aims to produce learning tools for Moral Cognitive Integrated PBL Learning Model, knowing the level of moral cognitive of PGSD Unipa Surabaya students and the influence of Moral Cognitive Integrated PBL Learning Model on Moral Cognitive of PGSD Unipa Surabaya Students. This type of research is R&D development research that has been simplified into three stages, namely preliminary studies, model development and model validation. The study population was all students of PGSD Class 2020 which consisted of seven classes, namely classes A-F. Whereas the sample of this study were students of PGSD Class 2020 Class A and Class F. The results of the study were the validation results…
Model development (conceptualisation)
2016
Chapter 2 provided the theoretical background for the development of the conceptual model. In this chapter, firstly, the constructs relevant for the model are conceptualised, and secondly, hypotheses regarding the relationships between those constructs are derived from theoretical considerations.
Simulation of stability and dynamics of multistage flash desalination
2011
gPROMS software was used to study the dynamics of a multistage flash desalination brine circulation system (MSF-BR) as a function of major operating parameters. Most of the previous studies focused on MSF-BR dynamic model development however; it gave very little information on dynamic response of the system to the most significant process independent parameters. The present model was first validated against available industrial data of different plants. System dynamics were obtained upon increasing/decreasing several of the operating parameters over a range of ± 15%. Results show that increase/decrease of the cooling seawater flow rate have limited effect on the system dynamics. Increasing/…
Formulation and validation of a reduced order model of 2D materials exhibiting a two-phase microstructure as applied to graphene oxide
2018
Abstract Novel 2D materials, e.g., graphene oxide (GO), are attractive building blocks in the design of advanced materials due to their reactive chemistry, which can enhance interfacial interactions while providing good in-plane mechanical properties. Recent studies have hypothesized that the randomly distributed two-phase microstructure of GO, which arises due to its oxidized chemistry, leads to differences in nano- vs meso‑scale mechanical responses. However, this effect has not been carefully studied using molecular dynamics due to computational limitations. Herein, a continuum mechanics model, formulated based on density functional based tight binding (DFTB) constitutive results for GO …
In sewer processes: mathematical model development and sensitivity analysis.
2009
Until now the majority of sewer networks in Italy have been built and managed considering small as well as local wastewater treatment plants (WWTPs). However, pushed by Italian and EU regulations, centralised and large WWTPs are becoming more common in Italy. One major technical aspect caused by the changing from local to centralised WWTPs is the development of significant in-sewer processes. These processes are also emphasized by the building of long interceptor sewers characterized by high hydraulic retention times and absence of tributary sewers. In this paper a model derived from the well known WATS model (Wastewater Aerobic/anaerobic Transformation in Sewers) has been set up and applie…
Experiment of Indoor Thermal Optimization of an Old Historic Building of Cluny through Digital Mock-up Simulation
2013
International audience; Improving energy efficiency is the first and most important step toward achieving sustainability in buildings. Buildings designed with sustainable solutions are usually energy-efficient because sustainable design is aimed at producing green buildings. In the case of historic buildings, however, this is quite challenging. Integrated building energy simulation programs have been used in various ways by building professionals to respond to these challenges and to improve building design with respect to sustainability. This poster presents a new approach toward optimizing thermal indoor energy using a digital mock-up simulation of a historical building to explore its pot…
