Safe, intelligent and explainable self-adaptive systems
Intelligent cyber-physical systems, such as self-driving cars, smart homes or e-health solutions, will increasingly influence our daily lives. They will deal with increasingly uncertain and changing environments and simultaneously must adhere to strict safety requirements. In addition, we need to …

Self Adaptive Methods for Parabolic Partial Differential Equations
In many applications, the solutions to important partial differential equations are characterized by a sharp active region of transition (such as wave fronts or areas of rapid diffusion) surrounded by relatively calm stable regions. The numerical approximation to such a solution is based on a mesh …

A Self -Adaptive Hybrid Genetic Algorithm for Optimal Groundwater Remediation Design
The application of the e-SAHGA algorithm to a hypothetical groundwater remediation design problem showed 90% reliability in identifying the solution faster than the SGA, with average savings of 64% across 100 runs with different random initial populations. Finally, e-SAHGA was tested on a …

Self-adaptive evolution of model structures and parameters / by Jason John Bobbin.
This thesis proposes a new self-adaptive, symbiotic model evolution framework SASME. SASME is described generally and then applied to the specific task of evolving rule sets with explicit default hierarchies for learning problems. Experiments are conducted on the SASME framework to establish the …

A Dynamic Self-Adaptive Wavelet-Based Method for Multiscale Electronic Structure Calculations
Results are presented for the model calculations of hydrogen and helium atoms using a general three-dimensional bare Coulomb potential, as well as a three-dimensional quantum dot.

Development of self-adaptive back propagation and derivative free training algorithms in artificial neural networks
Three new iterative, dynamically self-adaptive, derivative-free and training parameter free artificial neural network (ANN) training algorithms are developed. They are defined as self-adaptive back propagation, multi-directional and restart ANN training algorithms. The descent direction in …

Requirements Engineering for Self-Adaptive Software: Bridging the Gap Between Design-Time and Run-Time
Self-Adaptive Software systems (SAS) adapt at run-time in response to changes in user’s needs, operating contexts, and resource availability, by requiring minimal to no involvement of system administrators. The ever-greater reliance on software with qualities such as flexibility and easy …

An Exploratory Comparison of a Traditional and an Adaptive Instructional Approach for College Algebra
… ATMI also provided four sub-scales scores for self-confidence, value of learning, enjoyment, and motivation. Furthermore, this research explored and compared relationships between students' level of mastery and their actual level of learning. This study implemented a quasi-experimental research …

A Multiplicative Regularisation for Inverse Problems
This thesis considers self-adaptive regularisation methods, focusing particularly on new, multiplicative methods, in which the cost functional is constructed as a product of two terms, rather than the more usual sum of a fidelity term and a regularisation term. By re-formulating the multiplicative …

Uma estratégia de refinamento auto-adaptativo versão h do método dos elementos finitos aplicada a problemas bi-dimensionais regidos pela equação de campo
In this work a self-adaptive refinement procedure (h-version) for the Finite Element Method (FEM) solution of two dimensional potential problems is studied. The mesh refinement strategy and the a-posteriori error analysis are also discussed. The Galerkin formulation for FEM is utilized and the …
