An experimental study

Magnetic bearing systems have received much attention in the research community for the past decades. Its inherent nonlinearity and open-loop instability present challenges for controller design. This thesis investigates and designs model predictive control (MPC) systems for an experimental Active Magnetic Bearing (AMB) laboratory system. A host-target development environment of real-time control system with hardware in the loop (HIL) is used for implementation of the predictive control systems. In this thesis, both continuous and discrete time model predictive controllers are studied.

The primary aim of this research was to further develop the sensing and estimation module of the CHMS framework with an improved multimodal inference model of MWL as needed for the application in aerospace CPHS. Here the focus of this research was on the implementation of a multimodal inference model of MWL that would be developed and experimentally tested. This was done with the purpose of studying the viability of real‐time system adaptation in aerospace systems.

This study was experimental in nature and the research was based on a quantitative approach tailored to minimize threats to validity through the use of a control group. Additionally, it involved elements of related qualitative research to interpret findings. An empirically-based, working hypothesis was presented to the effect that, a greater potential of project success can be realized by introducing information on emotional development to enhance behavioral competencies of all project team members.

This study was an attempt to investigate the possible effects of integrating MI-based activities into developing the EFL students’ speaking skills, and then to find out the students’ evaluation of such an integration of MI-based activities. Therefore, to attain those two main objectives, the mixed research method was adopted: the quantitative approach utilizing a quasi-experimental study in which MI-based activities were integrated into an experiment.

Two blind analyses for 241Pu(nth,f) isobaric fission yields have been conducted, one analysis using a mix of a Monte-Carlo and an analytical method, the other one relying only on analytical calculations. The calculations have been derived from the same analysis path and experimental data, obtained on the LOHENGRIN mass spectrometer at the Institut Laue-Langevin.

The goal of this study is to demonstrate and quantify the impact that the uncertainty in thermophysical properties has on key metrics of thermal hydraulic importance for MSRs, in particular on the heat transfer coefficient. In order to achieve this, computational fluid dynamics (CFD) simulations using the RANS k-ω SST model were compared to published experiment data on molten salt.

The beneficial influence of dietary curcumin, capsaicin and their combina-tion on the susceptibility of low-density lipoprotein (LDL) to oxidation was examined in an animal study. Individually, both dietary curcumin and capsaicin significantly inhibited thein vivo iron-induced LDL oxidation, as well as copper-induced oxidation of LDLin vitro. The protective effect of the combination of curcumin and capsaicin on LDL oxidation was greater than that of individual compounds.

There are several different families of repeat proteins. In each, a distinct structural motif is repeated in tandem to generate an elongated structure. The nonglobular, extended structures that result are particularly well suited to present a large surface area and to function as interaction domains. Many repeat proteins have been demonstrated experimentally to fold and function as independent domains.

Experimental autoimmune encephalomyelitis can be induced in susceptible animals by immunodominant deter-minants of myelin basic protein (MBP). To characterize the molecular features of antigenic sites important for designing experimental autoimmune encephalomyelitis suppressing molecules, we report structural studies, based on NMR experimental data in conjunction with molecular dynamic simulations, of the potent linear dodecapeptide epitope of guinea pig MBP, Gln74-Lys75-Ser76-Gln77-Arg78-Ser79-Gln80-Asp81-Glu82-Asn83-Pro84-Val85 [MBP(74–85)], and its antagonist analogue Ala81MBP(74–85)....

The newly emerging field of systems biology involves a judicious interplay between high-throughput ‘wet’ experimentation, computational modelling and technology development, coupled to the world of ideas and theory. This interplay involves iterative cycles, such that systems biology is not at all confined to hypothesis-dependent studies, with intelligent, principled, hypothesis-generating studies being of high importance and consequently very far from aimless fishing expeditions.
