NMR relaxometry refers to the measurement of relaxation times (usually T1) as a function of magnetic field strength. It is usually accomplished using fast field-cycling (FFC), in which the magnetic field is switched rapidly between levels during the pulse sequence. By switching the magnetic field, the nuclear spins can “evolve” at a chosen magnetic field strength, after which the magnetic field...

In this paper, a simplified model with a lower order is first developed for a nuclear steam generator system and verified against some realistic environments. Based on this simplified model, a hybrid multi-input and multi-out (MrMO) control system, consisting of feedforward control (FFC) and feedback control (FBC), is designed for wide range conditions by using the genetic algorithm (GA) techni...

This paper designs and implements a hardware-based evolutionary digital filter (EDF). The EDF is an adaptive digital filter which is controlled by adaptive algorithm based on evolutionary computation. The hardware-based EDF consists of two submodules, that is, a filtering and fitness calculation (FFC) module and a reproduction and selection (RS) module. The FFC module has high computational abi...

It is known that in the early stages of osteoarthritis (OA) the concentration of glycan proteins decreases in articular cartilage. This phenomenon is under active research to develop a means to characterise OA accurately in the early stages of the disease, when still reversible. However, no method of quantification has yet shown clear success in this area. In this paper we propose a novel appro...

Abstruct-Formation flying is defined as a set of more than one spacecraft whose states are coupled through a common control law. This paper provides a comprehensive survey of spacecraft formation flying control (FFC), which encompasses design techniques and stability results for these coupled-state control laws. We divide the FFC literature into five FFC architectures: (i) Multiple-Input Multip...

This work proposes a floating-point to fixed-point conversion (FFC) methodology for digital VLSI signal processing systems. The past techniques used to facilitate FFC are first reviewed, followed by a description based on a statistical approach and global optimization which allows a high degree of automation.

The Face-to-Face Composition (FFC) Model is a modular, boundary-based description of an object. The Assembly AND/OR graph proposed by Homem de Mello and Sanderson for task planning is an efficient data structure showing all possible assembly sequences. It can be obtained directly from the FFC model by a sequence of component-merging operations.

Mit dem im Task Trainer (TT) integrierten Funktions-FragmentChecker (FFC) wurde für die C#-Programmierausbildung eine computergestützte Übungsumgebung geschaffen, in der der Lernende durch die eigenständige Auswahl von unterschiedlich komplexen Übungsaufgaben aus einem Pool verschiedener Aufgabentypen seinen Lernund Übungsprozess aktiv und selbstgesteuert gestalten kann. Unter Üben wird das Kon...

Fast Field-Cycling (FFC) is an NMR technique that involves changing the main magnetic field during the pulse sequence, which provides an extra dimension to the experimenter. It is a rich technique that is well known to characterise molecular dynamics with various applications already demonstrated in polymer matrices, porous media, liquid crystals and many other systems [1]. However, much work r...

Although the atherogenic role of dietary cholesterol has been well established, its diabetogenic potential and associated metabolic disturbances have not been reported. Diet-induced hamster models of insulin resistance and dyslipidemia were employed to determine lipogenic and diabetogenic effects of dietary cholesterol. Metabolic studies were conducted in hamsters fed diets rich in fructose (40...
