Abstract:
On the basis of the neurophysiological strength-duration (amplitude-duration) curve of neuron activation (which relates the threshold amplitude of a rectangular current pulse of neuron activation to the pulse duration), as well as with the use of activation energy constraint (the threshold curve corresponds to the energy threshold of neuron activation by a rectangular current pulse), an energy model of neuron activation by a single current pulse has been constructed. The constructed model of activation, which determines its spectral properties, is a bandpass filter. Under the condition of minimum-phase feature of the neuron activation model, on the basis of Hilbert transform, the possibilities of phase-frequency response calculation from its amplitude-frequency response have been considered. Approximation to the amplitude-frequency response by the response of the Butterworth filter of the first order, as well as obtaining the pulse response corresponding to this approximation, give us the possibility of analyzing the efficiency of activating current pulses of various shapes, including analysis in accordance with the energy constraint.

Abstract:
The influence of laser radiation on bulk and etch rates, and as well detector sensitivity, before and after being irradiated with alpha particles at 5 MeV emitted from a 241Am source, are examined at different etching temperatures (65, 67, 69, 71, 73, 75, 77, 79 ,81, 83, and 85)C in this paper. A laser source with a wavelength of 480 nm and a pulse energy of 50 mJ/pulse at a repetition rate of 9 Hz was used to investigate the activation energy of a CR-39 polymer. The rates of bulk etch, Vb, and track etch, Vt, slightly increase with laser radiation. Whereas sensitivity decreases as temperature increases, besides, alpha-laser samples have quite better sensitivity than other samples. The activation energies of the bulk etch rates, Eb, are equivalent to 0.94 ± 0.07, 0.88 ± 0.05, and 0.95 ± 0.06 eV for laser-alpha, alpha-laser, and no laser samples, respectively. While, the activation energies associated with track etch rate, Et, for the CR-39 samples under study are 0.86 ± 0.04, 0.77 ± 0.03, and 0.76 ± 0.03 eV. The results manifest that laser exposure has a slight influence on activation energies of bulk etch rate within experimental uncertainties of the CR-39 samples. Additionally, the CR-39 set of laser-alpha samples reveals that Et is increased based on the cross-linking process. The increase in Et relates to hardening of the detector material, which has several uses, specifically in radiation detection.

Abstract:
The kinetic (exchange currents, apparent elect-ron transfer coefficients) and energetic (activation energies of diffusion and electron-transfer reaction) parameters of electroreduction of palladium (II) bis-hydroxyethyliminodiacetate complexes from an ele-ctrolyte containing an excess of free ligand have been determined. A method is proposed for calculating the actual activation energy of the electrode process that is controlled by mixed kinetics, based on the dif-fusion activation energy, transition reaction and the ratio of surface and volume concentrations of potenti-al-determining ions in the solution under study or the ratio of the limiting diffusion current jd and dischar-ge current jk of palladium (II) hydroxyethyliminodi-
 
 acetate complexes. The actual activation energy Af of the electrode process, which is controlled by mixed kinetics, is calculated based on the diffusion activati-on energy, transition reaction and the ratio of the li-miting diffusion current jd and discharge current jk of palladium (II) bis-hydroxyethyliminodiacetate com-plexes. The contribution of the activation energy of the transition stage (slow discharge) and the diffusion activation energy of bis -hydroxyethyliminodiacetate palladium (II) complexes to the actual activation ener-gy of the electrode process limited by mixed kine-tics is determined. The dependence of actual activation energy on electrode process overpotential has been stu-died. The actual activation energy Af of the electro-de process varies from the value of the activation ener-gy of the transition reaction At (63.4 kJ×mol–1) to the value of the diffusion activation energy Ad (22.5 kJ ×mol–1). The activation energy calculated according to Tyomkin can be considered as the actual activation energy Af of the discharge stage at a given polarizati-on DE only with a purely kinetic control of the pro-cess rate. The activation energy experimentally deter-mined by the temperature-kinetic method according to the Arrhenius equation and calculated by the pro-posed method is the actual activation energy Af of the electrode process, controlled by mixed kinetics. There is a coincidence of the experimentally determi-ned by the Gorbachev method and the actual Af acti-vation energy of electrode process controlled by mi-xed kinetics calculated by the proposed method. A good agreement between the calculated and experi-mentally determined values of the actual activation energy of the electrode process is observed.

Abstract:
This research work focused on studying the emission spectroscopy produced from the high energy ion-molecule collision processes in mass spectrometry. The collision experiments are described and divided into 4 chapters (Chapter 3, 4, 5, 6).N2O+● is an ion of atmospheric importance. In chapter 3 the investigation of the collision between high translational energy (4-8 keV range) N2O+● ions and Helium target gas in mass spectrometry using collision induced emission (CIE) spectroscopy is described.In chapter 4, the collision-induced emission (CIE) spectra from 4-8 keV collisions between projectile He+● ions and CO2 target gas (He+●/CO2) were obtained. In Chapter 5, to probe the validity of this hypothesis, CIE experiments were carried out to observe the photon emissions from keV collisions of a selection of projectile ions with O2 target gas. By studying the resulting CIE spectra, a second potential mechanism came to light, one that involves the nearly isoenergetic O2+. A → X state transition. In chapter 6, neutral hydroxymethylene and formaldehyde were generated by charge exchange neutralization of their respective ionic counterparts and then were reionized and detected as recovery signals in neutralization-reionization mass spectrometry in the modified VG-ZAB mass spectrometer.

Abstract:
The objective of this work is to examine the effect of cement chemistry and physical properties on activation energy. Research efforts indicated that time dependent concrete properties such as strength, heat evolution, and thermal cracking are predictable through the concept of activation energy. Equivalent age concept, which uses the activation energy is key to such predictions. Furthermore, research has shown that Portland cement concrete properties are affected by particles size distribution, Blaine fineness, mineralogy and chemical composition. In this study, four Portland cements were used to evaluate different methods of activation energy determination based on strength and heat of hydration of paste and mortar mixtures. Moreover, equivalency of activation energy determined through strength and heat of hydration is addressed. The findings indicate that activation energy determined through strength measurements cannot be used for heat of hydration prediction. Additionally, models were proposed that are capable of predicting the activation energy for heat of hydration and strength. The proposed models incorporated the effect of cement chemistry, mineralogy, and particle size distribution in predicting activation energy.

Abstract:
Spent Nuclear Fuel (SNF) is a by-product of existing nuclear reactors; SNF consists of long-lived radioactive actinides which have an average half-life of several thousand years (e.g. Plutonium-239 with a half-life of 24,000 years, and Americium-243 with a half-life of 7,360 years). Several multinational organizations are making an attempt to extract the energetic value out of these nuclear stockpiles in order to minimize the risk of nuclear proliferation and reduce waste volume. The Inert Matrix Fuel (IMF) concept is being considered as an option to reuse the radioactive actinides present in spent nuclear fuel by means of a transmutation process. Due to the volatile nature of these radioactive actinides, it is expected that the high-temperature conventional processing of IMFs will result in a significant loss of material. This study investigates microwave sintering of inert matrix material (excluding actinide fuel) as an alternative route to conventional processing. It was observed that microwave sintering showed a reduction of 300°C in temperature required for full densification when compared to conventional sintering. The reduction in sintering temperatures did not show any significant variation in the resulting properties (hardness and grain size). While these results satisfy the need for the application, it is important to understand why microwaves enhance the sintering phenomena. It is speculated (by many researchers) that the electric field associated with microwave energy is enhancing flux leading to accelerated densification during microwave sintering. This study has observed a decrease in the activation energy (for sintering 8YZ) with the increase in the magnitude of the applied electric field.<br>Ph. D.

Abstract:
The cores of early UK graphite moderated research and production nuclear fission reactors operated at temperatures below 150°C. Due to this low temperature their core graphite contains significant amounts of stored (Wigner) energy that may be released by heating the graphite above the irradiation temperature. This exothermic behavior has lead to a number of decommissioning issues which are related to long term "safe-storage", reactor core dismantling, graphite waste packaging and the final disposal of this irradiated graphite waste. The release of stored energy can be modeled using kinetic models. These models rely on empirical data obtained either from graphite samples irradiated in Material Test Reactors (MTR) or data obtained from small samples obtained from the reactors themselves. Data from these experiments is used to derive activation energies and characteristic functions used in kinetic models. This present research involved the development of an understanding of the different grades of graphite, relating the accumulation of stored energy to reactor irradiation history and an investigation of historic stored energy data. The release of stored energy under various conditions applicable to decommissioning has been conducted using thermal analysis techniques such as Differential Scanning Calorimetry (DSC). Kinetic models were developed, validated and applied, suitable for the study of stored energy release in irradiated graphite components. A potentially valid method was developed, for determining the stored energy content of graphite components and the kinetics of energy release. Another parameter investigated in this study was dedicated in the simulation of irradiation damage using ion irradiation. Ion bombardment of small graphite samples is a convenient method of simulating fast neutron irradiation damage. In order to gain confidence that irradiation damage due to ion irradiation is a good model for neutron irradiation damage the properties and microstructure of various grades of ion irradiated nuclear graphite were also investigated. Raman Spectroscopy was employed to compare the effects of ion bombardment with the reported effects of neutron irradiation on the content of the defects. The changes of the of defect content with thermal annealing of the ion irradiated graphite have been compared with the annealing of neutron irradiated nuclear graphite.

Abstract:
Les travaux effectués ont consisté en une étude théorique du matériau BaSnO3 en tant que matériau conducteur protonique pour électrolytes de piles à combustible. Ces matériaux sont obtenus après un dopage aliovalent préalable qui génère des lacunes d'oxygène sur le sous-réseau d'oxygène du matériau. Ce matériau, placé en milieu humide va s'hydrater, c'est à dire que des molécules d'eau vont se dissocier au sein du matériau. La propriété principale souhaitée pour de tels matériaux est la conductivité protonique. Celle-ci dépend du nombre de porteurs de charges (les hydrogènes ou protons apportés par les molécules d'eau) et de leur mobilité. Ces deux paramètres sont quantifiés par des grandeurs thermodynamiques (l'enthalpies d'hydratation) et cinétiques (énergies d'activation) qui peuvent dépendre très fortement des dopants et de leur concentration. Une étude systématique a donc été entreprise sur ce matériau dopé par Ga, In, Y, Gd, Sm et La sur le site du Sn. Les objectifs étaient, d'une part de déterminer les paramètres clés de la conduction protonique et de les comparer aux données expérimentales, et d'autre part de corréler ces informations énergétiques aux effets structuraux imputables aux dopants, dans le but de comprendre comment ces derniers influencent la conduction. Pour remonter à ces paramètres, des calculs basés sur la Théorie de la Fonctionnelle de la Densité ont été réalisés dans l'approximation GGA-PBE, par l'intermédiaire de deux codes de calculs différents: ABINIT et SIESTA. Les calculs ont été menés à la fois à des concentrations de 12,5% et de 3,7% de dopants et le matériau BaTiO3 a également été étudié. D'intéressants résultats ont étés obtenus, notamment d'un point de vue structural, avec l'analyse des déformations locales aux alentours des dopants. Ont été mis en évidence: i. La stabilisation préférentielle de certaines positions des défauts due aux interactions électrostatiques. ii. L'effet de la concentration des dopants sur les énergies d'interaction entre dopant et défauts (lacune d'oxygène et proton) et iii. Un effet de taille de dopant, perceptible notamment dans le cas des gros dopants, et qui stabilise préférentiellement une autre position que celle favorisée d'un point de vue électrostatique<br>The present work consist in a theoretical study of the BaSnO3 compound as a protonic conductor for fuel cell electrolytes. These materials are obtained after an aliovalent doping stage that will create oxygen vacancies on the oxygen sublattice of the compound. Then, in a moist atmosphere, this lacunar material is going to hydrate: water molecule will be dissociated, creating protonic defects inside of the compound. The main desired property is the protonic conduction, which is due to two major contributions: number of charge careers (hydrogen or proton coming from the hydration reaction) and their mobility, at a given temperature. These two parameters are quantified by a thermodynamic quantity (hydration enthalpy) and a kinetic parameter (activation energy), which are known to be dependant on the dopant concentration. Thus, a systematic study has been done for the material doped Ga, In, Y, Gd, Sm and La on the Sn site. The objectives of this study were, first, to compute the key parameters of the protonic conduction and to compare them to the experimental data, and, in second, to correlate the calculated results to structural effect due to the dopants, in order to understand how they influence the conduction parameters. To determine these parameters, calculations based on the Density Functional Theory in the GGA-PBE form were carried out, using two different codes: ABINIT and SIESTA. Computations were done for dopant concentrations going from 12.5% to 3.7%, the BaTiO3 compound were also studied. Interesting results were also obtained, from a structural point of view, and concerning dopant local environment. Were evidenced: i. Prefential stabilization of defects, relatively to electrostatic interaction considerations. ii. The dopant concentration effect on dopant-defect (oxygen vacancy and proton) interactions. iii. A dopant size effect which acts in particular in the case of big dopants and which stabilize an other defect position than the one favoured by electrostatic considerations

Abstract:
Future sensor networks would comprise of sensing devices with energy harvesting capabilities from renewable energy sources such as solar power. A key research question in such sensor systems is to maximize the asymptotic event detection probability achieved in the system, in the presence of energy constraints and uncertainties. This thesis focuses on the design of adaptive algorithms for sensor activation in the presence of uncertainty in the event phenomena. Ideas from increase/decrease algorithms used in TCP congestion avoidance are applied to design an online and adaptive activation algorithm that varies the subsequent sleep interval according to additive increase and multiplicative decrease based upon the sensor's current energy level. In addition, the proposed algorithm does not depend on global system parameters, or on the degree of event correlations, and hence can easily be deployed in practical scenarios. Through extensive simulations, it is demonstrated that the proposed algorithm not only achieves near-optimal performance, but also exhibits more stability with respect to sensor's energy level and sleep interval variations.<br>Thesis (M.S.)--Wichita State University, College of Engineering, Dept. of Electrical Engineering and Computer Science

Abstract:
The application of plasma polymerized silicon-based coatings on plastic substrates is an effective way to adjust the permeability of the substrate. However, the permeation mechanisms are yet not fully understood. Here, the activation energy of permeation can offer valuable insights. In order to understand how the activation energy of permeation depends on the coating structure, five silicon-based coatings with varying oxygen content were analyzed, which led to property modifications ranging from silicon-oxidic to silicon-organic. Positron annihilation spectroscopy was employed to characterize the free volume and quartz crystal microbalance measurements were used to determine the density of the coating. These results were compared to water vapor permeation measurements with a temperature variation in the range of 15°C to 50°C. As expected, the silicon-organic coatings do not significantly impact the permeation rates, while the silicon-oxidic coatings do exhibit a barrier effect. The density of the coatings increases for the more silicon-oxidic coatings. A coating with an unusually high oxygen to precursor ratio forms the exception in both permeation and density. The free volume appears to increase for the more silicon-organic coatings. The pore wall chemistry is also affected, hinting at a structural transition from silicon-organic to silicon-oxidic. With this approach, we aim for an in-depth understanding of the chemical structure of silicon-based thin film coatings and its influence on gas permeation through those coatings.
