déplacement

Cette thèse s'appuie sur une constation initiale : en milieu urbain, les réseaux de voirie ne semblent pas être d'importants vecteurs de coopération intercommunale. Le double objectif de ce travail est donc de vérifier qu'il y ait effectivement dichotomie des réseaux urbains de voirie et de transpors publics au regard de la coopération intercommunale. L'intérêt de cette comparaison peut se justifier par la fonction commune de ces réseaux qui assurent tous deux le déplacement des ...

Literature,Romance literature

The metafictional novel is a novel that draws attention to its own form or construction and systematically flaunts its own condition of artifice, and by so doing poses questions about the relationship between fiction and reality. In other words, the metafictional novel is such that--explicitly or implicitly, and making use of a variety of strategies and techniques--deliberately exposes the fictiveness and artifice of the literary creation. As a tendency, the metafictional novel has been part of ...

The purpose of this research was to identify, describe, and analyze the extent of faculty participation in administrative decision making within selected schools of nursing. The style of participation was analyzed. The secondary purpose of the research was to observe whether the dean and faculty shared similar perceptions regarding the extent and style of participation in administrative decision making. This qualitative research study utilized in-depth interviews with the dean and two faculty me...

Nursing,Womens studies

This study examined moral reasoning used by nurses to resolve conflict and choice in the workplace. This study also focused on how nurses saw themselves as leaders and caregivers. Ten nurse leaders were purposively selected from a large urban acute care magnet hospital. In open-ended, semi-structured interviews, each participant discussed an actual workplace conflict that they experienced, the course of action taken, and evaluation. Nurse leaders also described themselves as leaders and as careg...

Linguistics,Language

Three questions are addressed about the subject in Japanese: (i) What is the subject? (ii) What is the topic in syntax? (iii) Where is the $\theta$-marked external argument in syntax? About (i), I adopt the widely accepted view that the subject is only a relative notion; SPEC. The SPEC is restricted in number in a clause, and so is the subject. The multiple subject construction is discussed in relation to this, because there appear to be infinitely many subjects in this construction. This casts ...

CUSUM-Kontrollkarte

The cumulative sum (CUSUM) technique is well-established in theory and practice of process control. A comprehensive exposition of the method is given, e.g., by Wetherill and Brown (1991). A question that is seldom treated in the literature is that on the effect of serial correlation of the control variable. Johnson and Bagshaw (1974) investigate the effect of correlation on the run length distribution when the control variable follows a first order autoregressive or moving average process. They ...

Physics, Molecular

The photoexcitation spectra of transition region species formed in bimolecular reactions of K + NaX (X = Cl, Br, I) have been observed by measuring the intensity of sodium D line emission at 589.0 nm as a function of excitation wavelengths between 595 and 640 nm. The portion of the spectrum measured for the K + NaCl system is qualitatively similar to that previously observed by Magurie, et al (MAG86). The spectra obtained for the K + NaBr and NaI systems are significantly different than that of ...

Language, Linguistics

Taiwanese has been analyzed either as a suppletive form of le or an equivalent of a higher abstract verb 'YOU', that asserts the existence of an event or a state. The latter seems plausible. However, when we carefully examine the various semantic functions of u, we find that they lack the constancy which would allow them to be united as a higher existential 'U'. This does not mean that there are various separate u's. We propose there is only one morpheme u. The 'major&#39...

The focus of this descriptive study was to determine parental attitudes and perceptions which deter parents from voluntarily becoming involved in the activities of their child's inner city elementary school. The research instrument used to determine both individual and collective impacts upon the relationships between the Home and School connection was a questionnaire. This questionnaire was sent out to 140 parents of inner city elementary school students. The targeted population was compose...

Mechanics

Problems for finite cracks on or near a bi-material interface were investigated. The crack under uniform pressure or a pair of concentrated loads on its faces was modelled by a dislocation density function along the crack length. For sub-interface crack problems, we investigated the case when the crack is near the interface of two half-planes and when the crack is near a coating-substrate system. In both cases the singular integral equations are of the first kind and were solved numerically by e...

The primary purpose of this study was to identify the way in which two groups, staff nurses and nurse administrators/managers, each conceptualize the ideal and actual role of the registered nurse practicing at the bedside. Data was examined in order to identify similarities and differences in the opinions of the two groups. A questionnaire with 35 items/situations using a Likert scale was developed. Items/situations were worded to conform to a five-point response format ranging from strongly agr...

Zoology,Paleontology

I investigated cranial and dental morphology in 37 species of fossil and living peccaries, Family Tayassuidae, from North and South America. PAUP analysis of 94 apomorphous character states among 33 species represented by adequate samples produced a set of trees (C.I. = 0.74) which unequivocally support the monophyly of several clades within the Tayassuidae. The subfamily Tayassuinae comprises the three living species of peccary and 23 Miocene and younger species. The Miocene taxa Hesperhys, &qu...

Computer Science

In many computational systems, tasks comprising numerical or symbolic data arrive at a processor periodically. Processing of the $i\sp{th}$ task has to stop before processing of the ($i$ + 1)$\sp{th}$ task begins, causing a hard constraint on $T\sb{p}(i)$: the time needed for complete processing of the $i\sp{th}$ task. Failing to meet this constraint means the processing is aborted and the output is deemed totally inaccurate or useless. To improve the probability of making real time, $T\sb{p}(i)...

program optimization

Introducing function sharing into designs allows eliminating costly structure by adapting existing structure to perform its function. This can eliminate many inefficiencies of reusing general componentssin specific contexts. "Redistribution of intermediate results'' focuses on instances where adaptation requires only addition/deletion of data flow and unused code removal. I show that this approach unifies and extends several well-known optimization classes. The system performs searc...

Artificial Intelligence

This thesis addresses the issue of applying a "globally" convergent optimization scheme to the training of multi-layer perceptrons, a class of Artificial Neural Networks, for the detection and classification of signals in single- and multi-user communication systems. The research is motivated by the fact that a multi-layer perceptron is theoretically capable of approximating any nonlinear function to within any specified accuracy. The object function to which we apply the optimization ...

Secretary of War Jefferson Davis was a vigorous champion of reform, aiming to enlarge the army, to increase its capabilities, and to foster military professionalism. The Crimean War offered an opportunity to send a delegation of officers to Europe to study military establishments there and to observe the latest technological advances under the trial of combat. During 1855 and 1856, Major Richard Delafield, Major Alfred Mordecai, and Captain George B. McClellan spent a year traveling through Euro...

The paper reports on the effects of multiple whole-body infra-red-A irradiational (IRA) on 13 male patients knows to have stage I or stage II essential arterial hypertension (WHO definition). The peripheral blood pressure was decreased significantly by IRA exposures. The lowered diastolic blood pressure lasted into post-treatment time. This effect is regarded as a consequence of an improvement in peripheral heamodynamics. A measure of this improvement is the different shape of the blood pressure...

Positively charged clusters of V, Nb, Ta, Co, Rh, Ir, and Ni in the size range of 3-26 atoms were generated by laser vaporization in a supersonic nozzle and injected into the ion trap of a Fourier transform ion cyclotron resonance apparatus, where they were studied by exposing them to hydrogen gas. Some clusters experience structural changes during the chemisorption process, and some clusters have multiple stable isomers. The reactivity of positive V, Nb, and Ta clusters toward H$\sb2$ increases...

The vegetable brassicas of cabbage, broccoli, and cauliflower are grown in Pukekohe for the Auckland fresh-produce markets. These brassicas are attacked by three major lepidopterous pests: diamondback moth (DBM) (Plutella xylostella (L)) (Yponomeutidae), white butterfly (WB) (Pieris rapae (L.)) (Pieridae), and soybean looper (SBL) (Thysanoplusia orichalcea (F.)) (Noctuidae). Current grower strategy to combat these pests is calendar-scheduled insecticide applications. The goal of this thesis is t...

Carbon monoxide adsorption, surface speciation and particle size distributions have been studied in platinum, palladium, and rhodium hydrosol systems using Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and transmission electron microscopy. In transmission electron micrographs of unprotected platinum and palladium hydrosols, particle necklacing believed to arise from sintering during preparation, is apparent. The average particle sizes of all hydrosols studied were in ...

Chemical engineering

Surface-catalyzed oxidation reactions commonly exhibit multiple steady states. While multiplicity often arises from a coupling of transport and chemical rate processes, it can also result from intrinsic interactions in the catalytic sequence. Carbon monoxide oxidation catalyzed by noble metals notoriously exhibits multiplicity behavior. In addition, reported multiplicity features of CO oxidation at different pressure conditions indicate apparent discrepancies. Observed multiplicity behavior can ...

This dissertation analyses export control programs in the Western state system. The main focus is Western alliance collaboration on East-West technology transfer controls through COCOM. It examines post-1945 intra-alliance and intra-national perspectives on the relationship between East-West trade and Western security. Within four historical periods (1949-1964, 1965-1979, 1979-1989, 1989-1991) four questions are addressed: (a) How does the structural distribution of power and the nature of Unite...

While it has been known for about 130 years that azeotropes are influenced by changing pressure, this fact has never been fully exploited. In this dissertation it is shown how pressure effects can be used to advantage or can foil attempts to distill homogeneous azeotropic mixtures and how an analysis of the fixed points of the distillation model leads to new important insights into extractive distillations. As the pressure varies, not only the composition but also the number of azeotropes can ch...

In model-based vision, there are a huge number of possible ways to match model features to image features. In addition to model shape constraints, there are important match-independent constraints that can efficiently reduce the search without the combinatorics of matching. I demonstrate two specific modules in the context of a complete recognition system, Reggie. The first is a region-based grouping mechanism to find groups of image features that are likely to come from a single object. The sec...

An improved Monte Carlo model for ionized impurity scattering is developed and applied to transport problems in Si and the Si$\sb{1-x}$Ge$\sb x$ alloy system. The model includes scattering cross sections derived from phase-shift analysis, implementation of the Friedel Sum Rule, and a simple phenomological model for multiple-potential scattering. Using a single adjustable parameter, majority and minority electron mobilities are calculated for Si and fit to experimental data. Experimental results for Si of $\mu\sb n(N\sb A)/\mu\sb n(N\sb D) \approx$ 2 at 300 K are reproduced and a value of 3 $< \mu\sb n(N\sb A)/\mu\sb n(N\sb D) <$ 4 is predicted at 77K. Low-field mobilities are then calculated for both strained and unstrained Si$\sb{1-x}$Ge$\sb x$ over wide ranges of doping, Ge mole fraction, and electric field, at 300K and 77K. A significant improvement in mobility (up to 50%) is observed for transport perpendicular to the growth plane in strained Si$\sb{1-x}$Ge$\sb x$, especially at 77K. High field MC simulations show that some strained mobility enhancement remains even at an electric field of 100 kV/cm. The improved model is then used in both DDE and Monte Carlo simulations at 300K and 77K of two strained-layer n-p-n Si$\sb{1-x}$Ge$\sb x$ HBTs with basewidths of 1000 A and 650 A and maximum Ge contents of 15% and 10% respectively. We find that as a result of improved mobility in the base and collector and velocity overshoot in the high field region, $h\sb{fe}$ and $f\sb T$ are improved significantly for the strained 650 A basewidth HBT as compared to a similar unstrained structure, especially at 77K.

A system has been developed to aid in the establishment of Agrobacterium-mediated transformation for new plant species. A series of binary vectors have been constructed that express a chimaeric β-D-glucuronidase (GUS) gene in plants cells but not in bacterial cells. This feature allows GUS activity from transformed plant cells to be assayed in the presence of Agrobacterium. Preliminary experiments examined the expression of these chimaeric GUS genes in transformed petunia leaf discs. GUS express...

Class mobility in farming works both ways, some farmer's children are unable to afford a farm, while others from non-farm families do succeed in farm ownership. The literature reviewed in this thesis suggests this situation is related to New Zealand's economic history. In the past small family farms have benefited from both secure markets and governments whose interests have been closely bound up with high productivity. This has led the state to offer cheap credit to prospective farmers ...

In this note we derive a simple formula for the density of Sn = i=1n Ti, where Ti is the duration of the i-th busy cycle in an M/M/1 queueing model with gamma distributed server vacations. Using this result we find the distribution of the queue length by standard renewal arguments. (author's abstract)

In this paper we will show that the theory of optimal experimental design leads to quite different patterns of measurement. These patterns take into account (a) the structure of the ongoing process and (b) what parameters or characteristics are object of inference. We will demonstrate that the use of optimal designs or of designs that are close to optimal ones allows to reduce the sample size without decreasing the accuracy of the results. In Section 2 we present a model that is suitable to desc...
