Data validation

This paper develops an Artificial Neural Network (ANN) model based on 96 experimental data to forecast the dynamic modulus of asphalt concrete mixtures. This study applied the repeated KFold cross-validation technique with 10 folds on the training data set to make the simulation results more reliable and find a model with more general predictive power.

n this work, the main aim is to map the potential zones of groundwater in Central Highlands (Vietnam) using a novel ensemble machine learning model, namely CG-LMT, which is a combination of two advanced techniques, namely Cascade Generalization (CG) and Logistics Model Trees (LMT). For this, a total of 501 wells data and a set of twelve affecting factors were gathered and selected to generate training and testing datasets used for building and validating the model.

In this thesis, a numerical model with detailed reaction mechanism which is tailored for studying the behaviour of combustion of natural gas has been introduced and validated with available experimental data. The numerical model attempts to comprehensively simulate the physical conditions (temperature and pressure), equivalent ratio, and fuel dilution and strain rate effect in the laminar flames.

The aims of this thesis are informed by the limitations of existing research identified above. The overall objective of the thesis is to develop and test a framework of accountant identities (accountant subtypes) inferred from stereotypical perceptions and to identify the attributes that underlie the subtypes. The initial construction of the framework is based on the accountant stereotypes identified in existing research. The framework is constructed from two dimensions based on role (tasks performed by accountants) and character (perceived personality traits).

To build trust across many sites (laboratories, regulatory agencies, contract research organizations, chemical producers, and the public), stakeholders will need to agree on validation requirements for particular uses (content in relation to context) as well as how results are to be communicated (data format), and measured (metrics). There is also a need for a global orchestrator, who can exert leadership and inspire voluntary cooperation of diverse organizations to address shared validation goals, to play a key role.

This study, however, focuses more on generally well-received blogs generated by widely accepted beauty writers aged 25-35 (the quality of well-received is defined by the number of followers in each page – averagely 10,000 and above). Additionally, for the collecting data of the study to be conducted thoroughly, entries with the occurrence of code-switch rather than randomly chronological posts are chosen as the primary material for valid and reliable linguistic analysis.

This study is a report on the validity of the hypothesis that students’ perception of the learning environment in a psychology classroom reflects their attitude, confidence and sense of satisfaction with regards to psychology. It examines data obtained from 110 students in 2 psychology classes of the Faculty of Education, An Giang University, to identify how students’ perceptions of the classroom learning environment varies and the extent to which this reflects attitudes, confidence and satisfaction.

The paper presents the ground effects on the flow over five NACA symmetrical airfoils by analyzing the coefficients of lift. The unbounded flow over a selected airfoil was first simulated, and the results were validated against the established data in order to validate the method used in obtaining the lift coefficients.
