Advances in NMR spectoscopy and imaging : Low-power rf-excitation and MRI of soils
Nuclear Magnetic Resonance (NMR) techniques have proliferated in many fields of science and technology like bio-sensing, chemical reaction monitoring and material characterization.Since the inception of NMR as an analytical tool, improving the sensitivity by increasing the field strength has been the primary development goal.However, in order to reduce cost and environmental impact, the trend to miniaturized NMR devices and its diverse application fields enjoys increasing interest.The first part of this thesis introduces novel insights into low-power rf-excitation, which is one crucial aspect for enabling further development in this direction, by employing Frank sequences.Based on experimental data, a detailed evidence of the power savings by excitation in the linear regime is given aiming at future elimination of the rf-amplifier from the NMR spectrometer so as to allow further mobility improvements.Selective excitation by colored Frank-sequence is reported, which bears promise for solvent signal suppression and motion tagging in magnetic resonance imaging (MRI).To this end, spectroscopic quality as well as image resolution with Frank excitation was significantly improved.The aim of the second part is to provide quantitative 3D moisture content patterns of natural soil samples on the microscale, which are essential for improving geological simulations on the field scale.In the course of this, the standardized imaging sequences ’zero echo time’ (ZTE) and ’ultra-short echo time’ (UTE) were employed but also Frank-sequence excitation was implemented, reflecting its first genuine application.In order to characterize water-retention behavior of the soil samples, ZTE experiments were combined with standardized geological methods like Multi-Step Outflow (MSO) and tensiometric measurements.Compared to the established way of acquiring water-retention data, the introduced method provides a fast and precise method with low effort.

Synchronous Generators and Excitation Systems Operating in a Power System : Measurement Methods and Modeling
In simulation tests of dynamic states of the power system (PS), the database of parameters of mathematical models of generating units is most commonly used.In many cases, the parameter values are burdened with large errors.Consequently, the results obtained are not reliable and do not allow drawing true conclusions.This monograph presents the developed methods and tools supporting the process of measurement determination of reliable values of parameters of mathematical models of synchronous generators and excitation systems.Special measurement tests are the basis for determining the parameters.The tests can be carried out in conditions of normal operation of generating units, in which electrical machines operate in the state of saturation of magnetic cores, and voltage regulators can reach limits.This book is intended for specialists in power engineering as well as students of faculties of electrical engineering interested in issues of PS transient states.

What is an excitation winding or an excitation field?
An excitation winding or excitation field is a component of an electrical machine, such as a generator or motor, that is responsible for creating a magnetic field. This magnetic field is essential for the operation of the machine, as it induces the necessary voltage or current in the stator or rotor windings. The excitation winding is typically connected to a DC power source, which provides the necessary current to create the magnetic field. In a generator, the excitation winding is used to produce the magnetic field that induces the voltage in the stator windings, while in a motor, the excitation field is used to create the necessary magnetic force for rotation.
-
What is the excitation voltage?
The excitation voltage is the voltage applied to a system or device to stimulate a response or output. It is used to activate sensors, transducers, or other components in a system. The excitation voltage is typically a controlled and known voltage level that is used to ensure accurate and consistent measurements or operations.

Does active and passive excitation have anything to do with saltatory and continuous excitation conduction?
Yes, active and passive excitation are related to saltatory and continuous excitation conduction. Active excitation occurs when an action potential is generated and propagated along the entire length of the axon, resulting in continuous excitation conduction. On the other hand, passive excitation occurs when the action potential is only generated at the nodes of Ranvier in myelinated axons, leading to saltatory excitation conduction. In saltatory conduction, the action potential "jumps" from one node to the next, allowing for faster conduction of the signal. Therefore, the type of excitation (active or passive) is directly related to the type of excitation conduction (continuous or saltatory).

What is excitation conduction in neurobiology?
Excitation conduction in neurobiology refers to the process by which an electrical signal, known as an action potential, is propagated along the length of a neuron. This signal is initiated by the opening of ion channels in response to a stimulus, causing a rapid change in membrane potential. The action potential then travels down the length of the neuron, allowing for communication between different parts of the nervous system. Excitation conduction is essential for the transmission of information within the brain and throughout the body.

Do plants have continuous excitation conduction?
No, plants do not have continuous excitation conduction like animals do. In plants, excitation conduction occurs through the movement of ions and electrical signals, but it is not continuous throughout the plant. Instead, it occurs in response to specific stimuli or signals, such as environmental changes or injury. This allows plants to respond to their surroundings and coordinate growth and development, but it is not a continuous process like in animals.
-
What is continuous passive excitation conduction?
Continuous passive excitation conduction is a process in which an electrical impulse is continuously conducted through a nerve or muscle fiber without the need for external stimulation. This can occur in certain pathological conditions, such as in the case of muscle spasms or certain types of nerve damage. In continuous passive excitation conduction, the electrical impulse is able to propagate along the nerve or muscle fiber without the need for an external stimulus, leading to continuous muscle contractions or abnormal nerve signaling.
-
What is the propagation of excitation in neurobiology?
The propagation of excitation in neurobiology refers to the transmission of electrical signals, known as action potentials, along the length of a neuron. When a neuron is stimulated, it generates an action potential that travels down its axon to communicate with other neurons or target cells. This propagation of excitation allows for the transmission of information throughout the nervous system, enabling processes such as sensory perception, motor control, and cognitive function. The speed and efficiency of this propagation are crucial for the proper functioning of the nervous system.
-
What is the speed of conduction of excitation?
The speed of conduction of excitation refers to the rate at which an electrical signal travels through a neuron. In myelinated neurons, the speed of conduction can reach up to 100 meters per second, while in unmyelinated neurons, it is much slower, around 1 meter per second. This difference in speed is due to the insulation provided by the myelin sheath, which allows the electrical signal to jump from one node of Ranvier to the next, speeding up the conduction process. The speed of conduction of excitation is crucial for the rapid transmission of information within the nervous system.
