description: Abstract

Creativity of organizational members (employees) is a hope for all types of organizations, because creativity will drive the dynamics and performance of the organization. Creativity can be influenced by several variables, including: work values, organizational culture and knowledge sharing. In several study results, knowledge sharing plays a role in mediating the influence of work values and organizational culture on creativity. This study aims to: analyze and evaluate the influence of work values and organizational culture on employee knowledge sharing and creativity, as well as the role of knowledge sharing in mediating the influence of work values and organizational culture on employee creativity at the Konawe Regency Regional Secretariat. The study population was 195 people with a sample of 131 people taken by cluster random sampling, in 13 parts of the research object. The data collection instrument used was a questionnaire. Data analysis was carried out using descriptive and inferential statistics with SmartPLS software version 4.0. Work values have a positive and significant effect on knowledge sharing, meaning that if work values improve, knowledge sharing will increase; 2) Work values have a positive and significant effect on employee creativity, meaning that if work values improve or increase, employee creativity will increase; 3) Work culture has a positive and significant effect on knowledge sharing, which means that if the organizational culture, then knowledge sharing will increase; 4) Organizational culture has a positive but not significant effect on employee creativity, which means that the improvement or creation of organizational culture that is applied has not had a significant impact on increasing employee creativity; 5) Knowledge sharing has a positive but not significant effect on employee creativity, which means that the knowledge sharing that is currently applied has not been able to encourage increased employee creativity in this research object; 6) Knowledge sharing acts as a partial mediation on the effect of work values on employee creativity 7) Knowledge sharing acts as a partial mediation on the effect of organizational culture on employee creativity.

description: Tree species providing non-timber forest products (NTFPs) have the potential to enhance the socio-economic value of forestry plantation systems and mitigate biodiversity loss associated with production landscapes in Southern Africa. This can be accomplished by integrating NTFP agroforestry systems with forestry plantation systems but raises questions around which species and products are suited to the different environments that exist within large plantation systems or plantation landscapes. These questions can be answered by assessing the NTFP and agroforestry system (AFS) value of native species that form part of secondary vegetation within forestry plantations by shedding light on the disturbance regimes and environmental conditions that NTFP species prefer. This study assessed the NTFP value of secondary vegetation growing within abandoned clear-felled and abandoned unharvested forestry compartments. It addressed differences between the NTFP value of secondary vegetation and natural forest while providing options for how native species could be integrated into a forestry plantation system using agroforestry. We found that secondary vegetation growing in abandoned compartments provided roughly two-thirds of the NTFP uses provided by natural forest. The state of the compartment at the time of abandonment influenced which NTFPs were available. Secondary woodland developing in clear-felled compartments contained NTFPs which were associated with fire-adapted woodland species (e.g. fruit and oils from Marula trees). Naturalising forest in unfelled plantation compartments contained a composition of NTFPs associated with the provision of wood products. Our results show that native vegetation growing as secondary vegetation in forestry plantation systems has the potential to guide the development of native species agro-forestry systems and, in general, can contribute to a more formalised approach for integrating NTFP supply in forestry plantation systems.
title: The Biology of the Utah Chub, Gila Atraria (Girard), of Scofield Reservoir, Utah
Creators: name: Olson, Harold F.
Publisher: name: Utah State University
Year: 1959

description: The Utah chub is one of the most important non-game fish in Utah. It has a wide range, and occurs in every drainage in Utah. The Utah chub is not important economically as food fish nor is it of much value commercially. The sportsmen think of this species as trash and do not consider catching or consuming the. However, the Utah chub may be caught on hook and like more readily than many game species. The Utah chub in Scofield Reservoir have been caught by trolling, bait fishing and fly casting and furnish considerable sport when caught with a light tackle.
Their real importance becomes evident when a large population of Utah chub exist in waters where game fish species are desired. With their high reproductive potential, the Utah chub may become the dominant species and cause trout populations to decrease. This competition for food and space has been evident in many areas. Hazzard (1935) stated that Utah chub and trout compete with trout for food in Fish Lake, Utah, and Sigler (1948) also found that Utah chub compete with trout for food.
Anisotropic dynamics of a vicinal surface under the meandering step instability

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We investigate the nonlinear evolution of the Bales-Zangwill instability, responsible for the meandering of atomic steps on a growing vicinal surface. We develop an asymptotic method to derive, in the continuous limit, an evolution equation for the two-dimensional step flow. The dynamics of the crystal surface is greatly influenced by the anisotropy inherent to its geometry, and is characterized by the coarsening of undulations along the step direction and by the elastic relaxation in the mean slope direction. We demonstrate, using similarity arguments, that the coalescence of meanders and the step flow follow simple scaling laws, and deduce the exponents of the characteristic length scales and height amplitude. The relevance of these results to experiments is discussed.

description: We perform statistical analysis on discrete nonlinear waves generated though modulational instability in the context of the Salerno model that interpolates between the intergable Ablowitz-Ladik (AL) equation and the nonintegrable discrete nonlinear Schrodinger (DNLS) equation. We focus on extreme events in the form of discrete rogue or freak waves that may arise as a result of rapid coalescence of discrete breathers or other nonlinear interaction processes. We find power law dependence in the wave amplitude distribution accompanied by an enhanced probability for freak events close to the integrable limit of the equation. A characteristic peak in the extreme event probability appears that is attributed to the onset of interaction of the discrete solitons of the AL equation and the accompanied transition from the local to the global stochasticity monitored through the positive Lyapunov exponent of a nonlinear map.

description: We present the asymptotic transitions from microscopic to macroscopic physics, their computational challenges and the Asymptotic-Preserving (AP) strategies to efficiently compute multiscale physical problems. Specifically, we will first study the asymptotic transition from quantum to classical mechanics, from classical mechanics to kinetic theory, and then from kinetic theory to hydrodynamics. We then review some representative AP schemes that mimic, at the discrete level, these asymptotic transitions, hence can be used crossing scales and, in particular, capture the macroscopic behavior without resolving numerically the microscopic physical scale.

title: Advancement to the Highest Faculty Ranks in Academic STEM: Explaining the Gender Gap at USU
Creators: name: Miegroet, Helga Van
Publisher: name: Utah State University
Year: 2018

description: Science and technology (S&T) disciplines at universities are still largely dominated by men, and few women are found in the highest employment ranks. Using the faculty data from Utah State University, this thesis explores the factors that help explain the difference in career trajectory between men and women in the S&T colleges. While there were few women in S&T colleges prior to the 1990s, more women have been hired since then, and the lower ranks of the faculty corps are starting to reflect the gender composition of the doctoral degree holders in the different fields. This is not the case for full professors and leadership positions, where women are still underrepresented. Analysis of the university careers of faculty in S&T colleges revealed that in the absence of formal guidelines, promotions to full professor were inconsistent, but men were generally promoted faster, especially when hired as associate professors. However, conscious measures by the university to make the promotion process more transparent and formalized reduced the variability in time to promotion to full professor for all faculty and minimized differences between men and women. Recognition of faculty achievement through awards still shows gender bias. Women proportionally receive less awards, especially in recognition of research activities. This study illustrates that clear guidelines reduce gender bias in decisions and improve gender equity in the academia.

description: We report Auger recombination rates for wurtzite InGaN calculated from first principles density-functional and many-body-perturbation theory. Two different mechanisms are examined -- inter- and intra-band recombination -- that affect different parts of the emission spectrum. In the blue to green spectral region and at room temperature the Auger coefficient can be as large as 2x10^-30cm^6s^-1; in the infrared even larger. Since Auger recombination scales with the cubic power of the free-carrier concentration it becomes an important non-radiative loss mechanism at high current densities. Our results indicate that Auger recombination may be responsible for the loss of quantum efficiency that affects InGaN-based light emitters.

Novelties Associated with a biodynamical interpretation of nuclear spin relaxation
Creators: name: Werbelow, Lawrence Glen
Publisher: name: University of British Columbia
Year: 2010

description: Employing the semiclassical form of the density operator theory of dynamic processes, the transient nuclear spin behavior is analyzed for a range of motional parameters of significance for biological interpretations of nuclear magnetic relaxation data. Only relaxation which results solely from the reorientational modulation of the various spin couplings is considered. The bath correlation functions which enter into the theory are assumed to be completely characterized by two unique motional constants (a dynamic symmetric top approximation). The effects of slow, anisotropic modulation of spin-spin and spin-molecule interactions on T₁, T₂, T₁ ratios, T₂ ratios, and Overhauser enhancements are discussed. It is rationalized that in general, any parameter dependent upon the spectral density at zero frequency is independent of the magnitude of the asymmetry in the motion. Likewise, parameters independent of the near-zero frequency spectral component often are sensitive solely to the magnitude of the motional asymmetry. These considerations are extended to multispin systems and spin systems where nuclear magnetic relaxation proceeds by competing interactions characterized by nonvanishing interference or cross-correlation functions. In general, one cannot define unambigiously a unique T₁ or T₂ in such a case as the predicted decay is multi-(non)exponential. The spin behavior in such a situation is thoroughly analyzed and many intriguing predictions are presented. It is seen that the failure of a white spectral density approximation or a single exponential decay of the molecular correlation function often leads to predictions of extreme nonexponentiality of the magnetization decay. While the results of these calculations are of general interest, they are especially pertinent for those concerned with biological applications of NMR. Finally, the initial concepts are extended to a discussion of the potentially powerful Perturbed Angular Correlation experiment where it is shown that the coincidence counting rate will in general be influenced by anisotropic modulation of the quadrupolar perturbation. It is emphasized that a conventional interpretation of relaxation data is impregnated with hidden, "extreme-narrowed", reasoning. Extensive figures are provided which not only facilitate experimental application of the calculations, but also provide striking evidence for the caution which must be exercised in any biodynamical interpretation of nuclear spin relaxation.
title: Sequential Analysis for Tolerances of Noxious Weed Seeds

Year: 1972

description: The application of a sequential test, the sequential probability ratio test, for the tolerances of noxious weed seeds is studied. It is proved that the sequential test can give a similar power curve to that of the current fixed sample test if the test parameters are properly chosen.
The average sample size required by a sequential test, in general, is smaller than that of the existing test. However, in some cases it requires relatively a larger sample than current test.
As a solution to the problem a method of truncation is considered. A kind of mixed procedure is suggested. This procedure gives almost an identical power curve to the standard one with great savings in sample size. The sample size is always less than that of the current test procedure.

description: M dwarfs are important targets in the search for Earth-like exoplanets due to their small masses and low luminosities. Several ongoing and upcoming space missions are targeting M dwarfs for this reason, and the ESA PLATO mission is one of these. In order to fully characterise a planetary system the properties of the host star must be known. For M dwarfs we can derive effective temperature, surface gravity, metallicity, and abundances of various elements from spectroscopic observations in combination with photometric data. The Stellar Abundances and atmospheric Parameters Pipeline (SAPP) has been developed as a prototype for one of the stellar science softwares within the PLATO consortium, it is aimed at FGK stars. We have modified it to be able to analyse the M dwarf among the PLATO targets. The current version of the pipeline for M dwarfs mostly relies on spectroscopic observations. The data processing is based on the machine learning algorithm The Payne and fits a grid of model spectra to an observed spectrum to derive effective temperature and metallicity. We use spectra in the H-band, as the near-infrared region is beneficial for M dwarfs. A method based on synthetic spectra was developed for the continuum normalisation of the spectra, taking into account the pseudo-continuum formed by numerous lines of the water molecule. Photometry is used to constrain the surface gravity. We tested the modified SAPP on spectra of M dwarfs from the APOGEE survey. Our validation sample of 26 stars includes stars with interferometric observations and binaries. We found a good agreement between our values and reference values from a range of studies. The overall uncertainties in the derived effective temperature, surface gravity, and metallicity is 100 K, 0.1 dex, and 0.15 dex, respectively. We find that the modified SAPP performs well on M dwarfs and identify possible areas of future development.

description: We present initial results from a population synthesis model aimed at determining the star formation rate of the Milky-Way. We find that a total star formation rate of 0.68 to 1.45 Msun/yr is able to reproduce the observed number of young stellar objects in the Spitzer/IRAC GLIMPSE survey of the Galactic plane, assuming simple prescriptions for the 3D Galactic distributions of YSOs and interstellar dust, and using model SEDs to predict the brightness and color of the synthetic YSOs at different wavelengths. This is the first Galaxy-wide measurement derived from pre-main-sequence objects themselves, rather than global observables such as the total radio continuum, Halpha, or FIR flux. The value obtained is slightly lower than, but generally consistent with previously determined values. We will extend this method in the future to fit the brightness, color, and angular distribution of YSOs, and simultaneously make use of multiple surveys, to place constraints on the input assumptions, and reduce uncertainties in the star formation rate estimate. Ultimately, this will be one of the most accurate methods for determining the Galactic star formation rate, as it makes use of stars of all masses (limited only by sensitivity) rather than solely massive stars or indirect tracers of massive stars.

description: Three cluster analysis programs were used to group the same 64 individuals, generated so as to represent eight populations of eight individuals each. Each individual had quantitative values for seven attributes. All eight populations shared a common attribute variance-covariance matrix.
The first program, from F. J. Rohlf's MINT package, implemented single linkage. Correlation was used as the basis for similarity. The results were not satisfactory, and the further use of correlation is in question.
The second program, MDISP, bases similarity on Euclidean distance. It was found to give excellent results, in that it clustered individuals into the exact populations from which they were generated. It is the recommended program of the three used here.
The last program, MINFO, uses similarity based on mutual information. It also gave very satisfactory results, but, due to visualization reasons, it was found to be less favorable than the MDISP program.
Francisco Pino: el poeta de los agujeros
Creators: name: Ortega, Esperanza
Publisher: name: Università degli Studi di Milano
Year: 2014

description: La obra de Francisco Pino (1910-2002), en sus dos vertientes, experimental y no-experimental, posee una coherencia absoluta en cuanto a su concepción creacionista, que considera el poema como «manifestación de existencia». En este contexto aparecen en los años setenta sus libros de agujeros troquelados, que son su característica más relevante y constituyen una muestra de osadía artística y rebeldía vital. Estos libros de agujeros, minúsculas maquetas del uni-verso, poseen un sentido metafísico-religioso: Pino representa en ellos el vacío y el silencio consustancial a la poesía como música inaudible y espacio invisible, y nos ofrece los planos de una arquitectura poética que comunica con el infinito por medio de la ventana troquelada. Hay una búsqueda de la palabra poética total en toda su obra, desde sus primeros versos, en los que ya aparecen intuiciones reveladoras de sus hallazgos posteriores. Aunque, para Pino, la poesía es búsqueda constante, persecución de una presa inalcanzable. En esa persecución, hallará los caligramas, los libros troquelados y los poemas visua-les realizados en todo tipo de soportes desechables, pues Pino afirmó siempre su deseo de permanecer en la órbita de lo efímero, ajeno al anhelo de eterni-dad y ajeno también a las convenciones de la Historia del Arte, aunque su postura condenara a su obra al ostracismo o la expusiera a la irrisión. En la ilustración de uno de sus últimos libros, el titulado Tejas: lugar de Dios. Obertura, un pájaro se deshace en el poema. Sin trino ni mensaje posible, el poeta recoge la pluma del pájaro y con ella escribe. Así pues, la poesía surge tras la destrucción del poeta, como consecuencia de su disolución en el texto, una inmolación feliz e inexplicable, que inunda de luz cegadora el poema, iluminándole, sin llegar a desvelar su misterio.

title: Asynchronous Logic Design with Flip-Flop Constraints
Creators: name: Cox, David Franklin

Year: 1974

description: Some techniques are presented to permit the implementation of asynchronous sequential circuits using standard flip-flops. An algorithm is presented for the RS flip-flop, and it is shown that any flow table may be realized using the algorithm (the flow table is assumed to be realizable using standard logic gates). The approach is shown to be directly applicable to synchronous circuits, and transition flip-flops (JK, D, and T) are analyzed using the ideas developed. Constraints are derived for the flow tables to meet to be realizable using transition flip-flops in asynchronous situations, and upper and lower bounds on the number of transition flip-flops required to implement a given flow table are stated.

description: The Markov chain process for predicting the occurence of a sequence of rainless days, a standard technique, is critically examined in light of the basic underlying assumptions that must be made each time it is used. This is then compared to a simple binomial model wherein an event is defined to be a series of rainless days of desired length. Computer programs to perform the required calculations are then presented and compared as to complexity and operating characteristics. Finally, an example of applying both programs to real data is presented and further comparisons are drawn between the two techniques.

description: How does the form of our surroundings impact the ways we feel? This paper extends the body of research on the effects that space and light have on emotion by focusing on critical features of architectural form and illumination colors and their spatiotemporal impact on arousal. For that purpose, we solicited a corpus of spatial transitions in video form, lasting over 60 minutes, annotated by three participants in terms of arousal in a time-continuous and unbounded fashion. We process the annotation traces of that corpus in a relative fashion, focusing on the direction of arousal changes (increasing or decreasing) as affected by changes between consecutive rooms. Results show that properties of the form such as curved or complex spaces align highly with increased arousal. The analysis presented in this paper sheds some initial light in the relationship between arousal and core spatiotemporal features of form that is of particular importance for the affect-driven design of architectural spaces.

title: An Evaluation of Truncated Sequential Test
Creators: name: Chang, Ryh-Thinn
Publisher: name: Utah State University
Year: 1975

description: The development of sequential analysis has led to the proposal of tests that are more economical in that the Average Sample Number (A. S. N.) of the sequential test is smaller than the sample size of the fixed sample test. Although these tests usually have a smaller A. S. N. than the equivelent fixed sample procedure, there still remains the possibility that an extremely large sample size will be necessary to make a decision. To remedy this, truncated sequential tests have been developed.
A method of truncation for testing a composite hypotheses is studied. This method is formed by mixing a fixed sample test and a sequential test and is applied to the exponential distribution and normal distribution to establish its usefulness.
It is proved that our truncation method can give a similar Operating Characteristic (O. C.) curve to that of corresponding fixed sample test if the test parameters are properly chosen. The average sample size required by our truncation method as compared with other existing truncation methods gives us a satisfactory result. Though the truncation method we suggested in this study is not an optimum truncation, it is still worthwhile, especially, when we are interested in the testing of a composite hypotheses.
K-shell excitation of molecules by fast electron impact
Creators: name: Wight, Gordon Robert
Publisher: name: University of British Columbia
Year: 2010

description: Energy loss spectra of 2.5 keV electrons, scattered by molecular targets through small angles, have been studied in the regions of the respective carbon, nitrogen, oxygen and fluorine K-edges and the sulfur LII,III edges. Electron energy loss spectra for diatomic, triatomic and polyatomic molecules have been studied. Discrete excitations have been interpreted in terms of the promotion of the respective K-shell electron to unfilled valence molecular orbitals and Rydberg orbitals. Most spectra show considerable structure above the respective K-edge, in addition to the normal K-continuum. This structure represents the simultaneous transitions of a K-shell and valence shell electrons (i.e. shake-up and shake-off events following the creation of an inner hole). In the case of molecular nitrogen and carbon monoxide, a simple core model was shown to provide an accurate description for the K-shell excited molecule. On the basis of this model, excitation and ionization energies for some exotic chemical species have been predicted from the relative energies observed in the K-shell energy loss spectra of a number of molecules. The agreement between the estimated (core analogy) and observed K-shell excitation energies for larger molecules is less satisfactory, possibly because of the large changes in molecular geometry which occur as a result of an election promotion. Finally, the carbon K-shell energy loss spectra of carbon disulfide, carbonyl sulfide and carbon tetraf1uoride show features which are possibly associated with the existence of an effective potential barrier in these molecules.

description: In this Letter, the radial velocity variability of the chemically peculiar star Epsilon Ursae Majoris ($ε$ UMa) from the sharp cores of the hydrogen lines is investigated. This study is based on the ELODIE archival data obtained at different phases of the rotational cycle. The star exhibits low-amplitude radial velocity variations with a period of P=5.0887 d. The best Keplerian solution yields an eccentricity e=0.503 and a minimum mass ~14.7$M_{\rm Jup}$ on the hypothesis that the rotational axis of $ε$ UMa is perpendicular to the orbital plane. This result indicate that the companion is the brown-dwarf with the projected semi-amplitude variation of the radial velocity $K_{\rm 2}$=135.9 km/sec and the sine of inclination times semi-major axis $a_{2}$sin(i)=0.055 au.

description: Four statistics used for the analysis of categorical data were observed in the presence of many zero cell frequencies in two way classification contingency tables. The purpose of this study was to determine the effect of many zero cell frequencies upon the distribution properties of each of the four statistics studied. It was found that Light and Margolin's C and Pearson's Chi-square statistic closely approximated the Chi-square distribution as long as less than one-third of the table cells were empty. It was found that the mean and variance of Kullbach's 21 were larger than the expected values in the presence of few empty cells. The mean for 21 was found to become small in the presence of large numbers of empty cells. Ku's corrected 21 statistic was found, in the presence of many zero cell frequencies, to have a much larger mean value than would be expected in a Chi-square distribution. Kullback's 21 demonstrated a peculiar distribution change in the presence of large numbers of zero cell frequencies. 21 first enlarged, then decreased in average value.

description: As countries interact more and more, technology gains a decisive role in facilitating today's increased need for interconnection. At the same time, systems, becoming more advanced as technology progresses, feed each other and can produce highly complex and unpredictable results. However, with this ever-increasing need for interconnected operations, complex problems arise that need to be effectively tackled. This need extends far beyond the scientific and mechanical fields, covering every aspect of life. Systemic Thinking Philosophy and the System Dynamics methodology now seem to be more relevant than ever and their practical implementation in real-life industrial cases has started to become a trend. Companies that decide to implement such approaches can achieve significant improvements to the effectiveness of their operations and gain a competitive advantage. This research, influenced by the Systemic Thinking Philosophy, applies a System Dynamics approach in practice by improving the quality control process of a pharmaceutical company. The process is modeled, simulated, analyzed, and improvements are performed to achieve more effective and efficient operations. The results show that all these steps led to a successful identification and optimization of the critical factors, and a significant process improvement was achieved.

description: We present a hard X-ray spectrum of unprecedented quality of the Galactic supernova remnant W49B obtained with the Suzaku satellite. The spectrum exhibits an unusual structure consisting of a saw-edged bump above 8 keV. This bump cannot be explained by any combination of high-temperature plasmas in ionization equilibrium. We firmly conclude that this bump is caused by the strong radiative recombination continuum (RRC) of iron, detected for the first time in a supernova remnant. The electron temperature derived from the bremsstrahlung continuum shape and the slope of the RRC is 1.5 keV. On the other hand, the ionization temperature derived from the observed intensity ratios between the RRC and K-alpha lines of iron is 2.7 keV. These results indicate that the plasma is in a highly overionized state. Volume emission measures independently determined from the fluxes of the thermal and RRC components are consistent with each other, suggesting the same origin of these components.

title: Shooting Method for Two-Point Boundary Value Problems
Creators: name: Baumann, John D.
Publisher: name: Utah State University
Year: 1976

description: The purpose of this paper is to develop the shooting method as a technique for approximating the solution to the two-point boundary value problem on the interval [a,b] with the even order differential equation {i.e. n is even)
u(n)(t) + f(t, u(t), u(i)(t, ),..., u(n-1)(t)) = 0
and boundary conditions
u(a) = A
u(b) = B
and with at most n-2 other boundary conditions specified at either a or b. The basic proceedure will be illustrated by the following example.
Consider the two-point boundary value problem (0.1) (0.2) (0.3) with the additional boundary conditions
u(i)(a) = mi
for i = 1, ... ,k-1,k+l, ... ,n-1. The first step is to find values m1 and m2 such that the solutions or "shots", u1(t) and u2(t), to (0.1) that satisfy the initial conditions
u(a) = A
u(k-1)(a)= mk-1
u(k)(a) = m1
u(k+1)(a) = mk+l
u(n-1)(a) = mn-1
with 1 = 1,2, respectively, with the property that
u1(b) < B < u2(b).
The interval [m1,m2] is then searched by seccussive bisection to find the value, m, such that the solution or "shot", u(t), to the initial value problem with (0.1) and initial conditions
u(a) = A
u(k-1)(a)= mk-1
u(k)(a) = m1
u(k+1)(a) = mk+l
u(n-1)(a) = mn-1
has the property that u(b) = B.

description: Disordered assemblies with maximum packing fraction are studied by discrete element numerical simulation for monodisperse or bidisperse spherical particles, the diameter ratio being set at three. A maximum packing fraction value corresponds to an equilibrium state under isotropic loading of rigid frictionless particles. A statistical study of size effects enables one to evaluate, in the limit of large systems, the maximum packing fractions of both monodisperse assemblies, for which the conventional value 0.639 is retrieved, and bidisperse ones, for two distinct values of the coarse particle volume fraction. An enduring initial assembling step in which agitated grains interact through collisions induces an increase in the final packing fraction due to crystalline order nucleation for a monodisperse system or to a gradual segregation for a binary mixture. Albeit slow and moderate in a number of practical situations, this effect leads to a definition of the random close packing state, as the one obtained with frictionless rigid grains under an isotropic pressure in the limit of fast assembling processes. A few potential extensions to this preliminary study are suggested.

title: Interpretation and Application of Elements of Differential Geometry and Lie Theory
Creators: name: Brannan, James R.
Publisher: name: Utah State University
Year: 1976

description: Basic concepts of differential geometry and Lie theory are introduced. Lie transformation groups are applied to linear systems of differential equations and the problem of describing rigid body orientation. Linear Hamiltonian systems are then treated as a Lie system of differential equations. This theory is applied to a particular Hamiltonian system arising from a problem in control theory, the linear state regulator problem.
title: Positive Controllability of Systems with Nearly-Non-Negative Matrices
Creators: name: Perry, Theodore Sonne
Publisher: name: Utah State University
Year: 1976

description: This paper analyzes the controllability of constant coefficient linear differential equations and presents two proofs of a major theorem on controllability. Properties of nearly-non-negative matrices are discussed and in particular a theorem on the behavior of the exponential matrix of nearly-non-negative matrices is proven. These results are then used to prove that the reachable set for systems with nearly-non-negative matrices is limited to the positive hyperoctant.

description: A metal oxide support and a catalytically active metal are the two main ingredients for complex catalysts used in heterogeneous catalysis. The gas environment can change the catalyst during the reaction, modifying its structural and electronic properties. Here, we use monochromated electron energy loss spectroscopy (EELS) to reveal hydrogen-pressure-dependent changes of the electronic structure at the Pd/rutile-TiO$_2$ interface in an environmental transmission electron microscope (ETEM). Hydrogen-induced changes are observed in rutile-TiO$_2$ within $2$~nm from the interface at $10$~Pa of hydrogen pressure, in the Ti $L_{3,2}$ EEL spectra. Lower pressures such as $1$~Pa show no changes in the EEL spectra. We attribute the observed changes in the EEL spectra to hydrogen-induced defects accumulating in the vicinity of the interface. Based on DFT calculations, we developed a thermodynamic multistate defect (TMD) model of the interface and the bulk of the rutile-TiO$_2$. This TMD model predicts high concentrations of positively charged defects accumulating at the interface. The presence of the Schottky barrier stabilizes these defects by significantly lowering their formation energy. Our findings provide important new insights into catalytic processes taking place at metal/metal oxide interfaces in hydrogen gas environments.

title: Interpretation of Principal Components
Creators: name: Dabdoub, Marwan A.
Publisher: name: Utah State University
Year: 1978

description: The principal component analysis can be carried out two ways. First the R-mode:
R = K'K
and the second is the Q-mode:
Q = K K'
where K is a data matrix centered by column or by row. The most commonly used method is the R-mode.
It has been suggested that principal components computed from either the R-mode or the Q-mode may have the same interpretation. If this is true, then interpretation of the principal components could be put on a much more intuitive level in many applications. This will occur whenever one type of principal component is more intuitively related to the physical or natural system being studied than the other.
The relationship between the principal components of the R-mode and the Q-mode have been investigated with the result that they show a perfect correlation between them. The conclusion that the principal components of the R-mode or the Q-mode have the same interpretation is established.
An example is given to illustrate this work. The resulting interpretation is found to be the same as that obtained by Donald L. Phillips (1977) using different methods.
