Résumé :

Different distortion classes of the azimuthal and cylindrical projections of the triaxial ellipsoid have been considered in our previous works. These projections make it possible to construct maps of the celestial bodies in planetary scale. However, for regions in the middle latitudes it is advisable to use a conic projection which was not developed until now. In this investigation we describe the development of three conic projections of a triaxial ellipsoid: a conic projection with true scale along meridians, an equal-area conic projection and a quasi-conformal conic projection. In derivation of the projections we use an elliptical cone tangent to a triaxial ellipsoid. The projections are calculated and maps in these projections are created for the first time.

Résumé :

Principal components analysis (PCA) is effective at compressing information in multivariate data sets by computing orthogonal projections that maximize the amount of data variance. Unfortunately, information content in hyper spectral images does not always coincide with such projections. We propose an application of projection pursuit (pp), which seeks to find a set of projections that are "interesting" in the sense that they deviate from the Gaussian distribution assumption. Once these projections are obtained, they can be used for image compression, segmentation, or enhancement for visual analysis. To find these projections, a two –step iterative process is followed where we first search for a projection that maximizes a projection index based on the information divergence of the projections estimated probability distribution from the Gaussian distribution and then reduce the rank by projections the data on to the subspace orthogonal to the previous projection . To calculate each projections, we use a simplified approach to maximizing the projection index, which does not require optimization algorithm. It searches for a solution by obtaining a set of candidate projections from the data and choosing the one with the highest projection index. The effectiveness of the method is demonstrated through simulated examples as well as data from the hyper spectral digital imagery collection experiment and the spatially enhanced broadband and array spectrograph system.

Résumé :

We study the classes of invariant and natural projections in the dual of a Banach algebra $A$. These type of projections are relevant by their connections with the existence problem of bounded approximate identities in closed ideals of Banach algebras. It is known that any invariant projection is a natural projection. In this article we consider the issue of when a natural projection is an invariant projection.

Résumé :

Background There are surprisingly few resources available which offer an introductory guide to preparing a national population projection using a cohort-component model. Many demography textbooks cover projections quite briefly, and many academic papers on projections focus on advanced technical issues. Aims The aim of this paper is to provide a short and accessible guide to producing a national-scale population projection using the cohort-component model. Data and methods The paper describes the cohort-component model from a population accounting perspective, presents all the necessary projection calculations, and covers the key steps which form part of the projections preparation process – from gathering input data to validating outputs. An accompanying Excel workbook implements the model and contains example projections for Australia. Conclusions Calculating a national population projection using a cohort-component model involves fairly simple algebra, but the broader projections preparation process is more complex, and requires careful consideration and judgement.

Texte intégral

Résumé :

<p><strong>Abstract.</strong> There is no standard or generally accepted terminology of aspect in the theory of map projections. The term is probably derived from the concept that a graticule is produced by perspective projection of the meridians and parallels on a sphere onto a developable surface. Developable surfaces are widely accepted, and it is almost impossible to find a publication that deals with map projections in general and without developable surfaces story. If found, it usually classifies projections as cylindrical, conical and azimuthal, and applies developable surfaces to define the projection aspect. This paper explains why applying developable surfaces in the interpretation of map projections is not recommended, nor defining the aspect of all projections by the position of a midpoint as polar, equatorial, or oblique. In fact, defining a projection aspect this way is invalid in general, and obscures the fact that the aspect depends on the class to which a particular map projection belongs.</p>

Résumé :

In maintaining consistencies, such as GAC*, FDGAC* and weak EDGAC*, for global cost functions, Weighted CSP (WCSP) solvers rely on the projection and extension operations, which entail the computation of the cost functions' minima. Tractability of this minimum computation is essential for efficient execution. Since projections/extensions modify the cost functions, an important issue is tractable projection-safety, concerning whether minimum cost computation remains tractable after projections/extensions. In this paper, we prove that tractable projection-safety is always possible for projections/extensions to/from the nullary cost function (W0), and always impossible for projections/extensions to/from n-ary cost functions for n > = 2. When n = 1, the answer is indefinite. We give a simple negative example, while Lee and Leung's flow-based projection-safe cost functions are also tractable projection-safe. We propose polynomially decomposable cost functions, which are amenable to tractable minimum computation. We further prove that the polynomial decomposability property is unaffected by projections/extensionsto/from unary cost functions. Thus, polynomially decomposable cost functions are tractable projection-safe. We show that the SOFT_AMONG, SOFT_REGULAR, SOFT_GRAMMAR and MAX_WEIGHT/MIN_WEIGHT are polynomially decomposable. They are embedded in a WCSP solver for extensive experiments to confirm the feasibility and efficiency of our proposal.

Résumé :

This paper is dedicated to the mapping of conic projections and their appliance in producing maps of our state cartography. So far they were often applied, and will be used precisely coned, polyconed and modified polyconed projections for the official mapping (1:500 000, 1:750 000, 1:1000 000 and 1:1500 000). In particular, they cartographic conical projection at a scale of 1:1000 000 were taken into consideration. Those are the Lambert conformal conical projection with two standard parallels and the Modified polyconic projections. In addition to these cartographic conical projections, is described Boneo`s pseudoconic equivalent projections. This is one of the cartographic conical map projection that is commonly used in the preparation of thematic maps as well as for atlas editions of geographic maps both in Serbia and abroad.

Texte intégral

Résumé :

A review of projection methodologies used to project sub-acute inpatient activity in various international health care jurisdictions was undertaken as part of a project to develop subacute inpatient activity projections for the state with the largest population in Australia. The literature search identified nearly 200 articles and found three main groups of projection methodologies: projections with a focus on subacute care; projections with a focus on acute care, but which often included subacute activity in the overall projections; and projections of specific diseases/conditions influencing the demand for subacute care. In terms of the examples in the literature specifically regarding subacute care, the most common method of estimating current or future need was the use of normative benchmark ratios of beds to population. This was mainly to provide a policy basis to encourage development of subacute services, but also because of convenience. In the literature regarding acute activity projection methodologies, many incorporated subacute activity in the overall activity measures of the acute hospital unit. The most common method of acute care activity projection was use of current or trended utilisation rates applied to population projections. It appears that a significant amount of planning and demand projection being undertaken internationally on subacute care takes place within acute care methodologies. In regard to the potential use of specific diseases/ conditions that drive demand for subacute care, such as stroke or cancer, it is suggested that the best use of these disease-specific projections is in reality testing the results of other modelling. A number of conclusions are made and issues highlighted regarding projections of subacute inpatient activity.

Résumé :

Dopaminergic neurons in the VTA send projections to different forebrain structures, forming a complex crucial neuromodulatory system. Prefrontal, orbitofrontal and cingulated cortices receive the most marked innervation from the VTA; projections from the VTA to the medial prefrontal cortex (mPFC) constitute a portion of the mesocortical dopamine system. Much of this connectivity is bidirectional. Furthermore, the mesocortical dopamine system is involved in a great variety of brain functions, such as working memory, attention selection and memory retrieval, because of its interconnections with brain areas processing external information as well as internal information (Miller et al., 2002). Dopaminergic afferents from the mesencephalon seem to have a crucial role in the normal development of the PFC as well as in the regulation of neuronal activity in this brain area (Lewis et al., 1998). In fact, an abnormal maturation and alterations of the mesocortical projections to the PFC have been suggested to be involved in the development of psychostimulant-induced sensitization and in the pathophysiology of several disorders, such as schizophrenia, addiction or attention- deficit/hyperactivity disorder. The analysis of the formation and development of functional connections in the Central Nervous System needs suitable model systems to understand the basic, functional mechanisms (Hofmann et al., 2004). We have reconstructed parts of the mesocorticolimbic dopaminergic system using the model of organotypic co-cultures of tissue slices from the VTA/SN-complex and the PFC. In fact, organotypic brain slices are closer to the in vivo situation than cell cultures and they represent the most intact culture system for studying cortex function in isolation (Gähwiler et al., 1997; Karpiak and Plenz, 2002; Stewart and Plenz, 2008); furthermore, by combining organotypic cultures with microelectrode array (MEA) recordings, it is possible to simultaneously and repeatedly perform extracellular, non-invasive, multi-site recordings from electrodes covering the whole preparation, and to monitor long- term processes of neurite outgrowth and development and synapse formation at a functional level (Egert et al., 1998; Beggs and Plenz, 2003 and 2004; Hofmann et al., 2004). The aim of the present study was to characterize the developmental features of the VTA/SN-PFC co-cultures maintained on multielectrode array platforms, in order to study the functionality of the neuronal projections which have been demonstrated to grow in vitro between the two areas of the cultures (Franke et al., 2003; Heine et al., 2007). Furthermore, we validated the system as an useful pharmacological tool to study the effects of different neuromodulatory substances.

Résumé :

Daily fantasy sports (DFS) has grown in popularity with millions of participants throughout the world. However, studies have shown that most profits from DFS contests are won by only a small percentage of players. This thesis addresses the challenges faced by DFS participants by evaluating sources that provide player projections for NBA DFS contests and by developing machine learning models that produce competitive player projections. External sources are evaluated by constructing daily lineups based on the projections offered and evaluating those lineups in the context of all potential lineups, as well as those submitted by participants in competitive FanDuel DFS tournaments. Lineups produced by the machine learning models are also evaluated in the same manner. This work experiments with several machine learning techniques including automated machine learning and notes the top model developed was successful in 48% of all FanDuel NBA DFS tournaments and 51% of single-entry tournaments over a two-month period, surpassing the top external source evaluated by 9 percentage points and 10 percentage points, respectively.

Résumé :

Interstitial and intracavitary brachytherapy plays an essential role in management of several malignancies. However, the achievable accuracy of brachytherapy treatment for prostate and cervical cancer is limited due to the lack of intraoperative planning and adaptive replanning. A major problem in implementing TRUS-based intraoperative planning is an inability of TRUS to accurately localize individual seed poses (positions and orientations) relative to the prostate volume during or after the implantation. For the locally advanced cervical cancer patient, manual drawing of the source positions on orthogonal films can not localize the full 3D intracavitary brachytherapy (ICB) applicator geometry. A new iterative forward projection matching (IFPM) algorithm can explicitly localize each individual seed/applicator by iteratively matching computed projections of the post-implant patient with the measured projections. This thesis describes adaptation and implementation of a novel IFPM algorithm that addresses hitherto unsolved problems in localization of brachytherapy seeds and applicators. The prototype implementation of 3-parameter point-seed IFPM algorithm was experimentally validated using a set of a few cone-beam CT (CBCT) projections of both the phantom and post-implant patient’s datasets. Geometric uncertainty due to gantry angle inaccuracy was incorporated. After this, IFPM algorithm was extended to 5-parameter elongated line-seed model which automatically reconstructs individual seed orientation as well as position. The accuracy of this algorithm was tested using both the synthetic-measured projections of clinically-realistic Model-6711 125I seed arrangements and measured projections of an in-house precision-machined prostate implant phantom that allows the orientations and locations of up to 100 seeds to be set to known values. The seed reconstruction error for simulation was less than 0.6 mm/3o. For the physical phantom experiments, IFPM absolute accuracy for position, polar angle, and azimuthal angel were (0.78 ± 0.57) mm, (5.8 ± 4.8)o, and (6.8 ± 4.0)o, respectively. It avoids the need to match corresponding seeds in each projection and accommodates incomplete data, overlapping seed clusters, and highly-migrated seeds. IFPM was further generalized from 5-parameter to 6-parameter model which was needed to reconstruct 3D pose of arbitrary-shape applicators. The voxelized 3D model of the applicator was obtained from external complex combinatorial geometric modeling. It is then integrated into the forward projection matching method for computing the 2D projections of the 3D ICB applicators, iteratively. The applicator reconstruction error for simulation was about 0.5 mm/2o. The residual 2D registration error (positional difference) between computed and actual measured applicator images was less than 1 mm for the intrauterine tandem and about 1.5 mm for the bilateral colpostats in each detector plane. By localizing the applicator’s internal structure and the sources, the effect of intra and inter-applicator attenuation can be included in the resultant dose distribution and CBCT metal streaking artifact mitigation. The localization accuracy of better than 1 mm and 6o has the potential to support more accurate Monte Carlo-based or 2D TG-43 dose calculations in clinical practice. It is hoped the clinical implementation of IFPM approach to localize elongated line-seed/applicator for intraoperative brachytherapy planning may have a positive impact on the treatment of prostate and cervical cancers.

Résumé :

Les neurones à projection callosale (CPN) sont une sous-population de neurones néocorticaux qui relient les hémisphères cérébraux par le corps calleux, la plus grande commissure chez les mammifères non placentaires. Les CPNs varient dans leur position laminaire, identité moléculaire, morphologie somatodendritique et cibles axonales. La plupart des CPNs projettent de façon homotopique dans le cortex controlatéral, et certains CPNs projettent vers des régions corticales ou sous-corticales (ex. striatum) non homologues. Les mécanismes régissant le développement de ces CPNs à projection hétérotopique sont actuellement inconnus. Ici, j'ai étudié le récepteur PlexinD1 comme marqueur potentiel des CPNs à projections hétérotopiques. J'ai trouvé que PlexinD1 est exprimé au cours du développement et maintenu dans le cerveau adulte, où il est localisé dans les couches 4 et 5A. Les neurones positifs à PlexinD1 expriment le facteur de transcription Satb2 qui définit les CPNs. Le traçage axonal rétrograde a montré que les CPNs à projection hétérotopique du cortex moteur et somatosensoriel sont spécifiquement localisés dans la couche 5A et expriment PlexinD1. L'ablation génétique de PlexinD1 ou de son ligand Sema3E provoque un mauvais positionnement des CPNs à projection hétérotopique dans les couches corticales supérieures, alors que la surexpression de PlexinD1 dans les neurones des couches supérieures entraîne un mauvais positionnement des cellules dans les couches corticales profondes. Ces résultats indiquent que la signalisation PlexinD1 contrôle la position laminaire des CPNs à projection hétérotopique en régulant leur migration radiale pendant le développement néocortical
Callosal projection neurons (CPN) represent a subpopulation of neocortical neurons that interconnect the two brain hemispheres through the corpus callosum, the largest commissural tract in non-placental mammals. CPNs exhibit diversity in terms of laminar position in the neocortex, molecular identity, somatodendritic morphology and axonal targeting. For example, most CPNs send homotopic axonal projections to homologous areas of the contralateral cortex, while subgroups of CPNs send heterotopic projections to non-homologous cortical or subcortical (eg. striatum) regions. The mechanisms governing the development of heterotopically projecting CPNs are currently unknown. To address this question, I studied the axon guidance receptor PlexinD1 as a potential marker of CPNs with heterotopic projections. I found that PlexinD1 is expressed in the developing cortical plate and is maintained in the adult brain, where it mainly localized to layer 4 and 5A. PlexinD1-positive neurons were found to express the transcription factor Satb2 that define CPNs. Retrograde axonal tracing showed that heterotopically projecting CPNs in the motor and somatosensory cortex are specifically localized to layer 5A and express PlexinD1. Genetic ablation of PlexinD1 or its Sema3E ligand in the cortex caused mispositionning of heterotopically projecting CPNs in upper cortical layers, whereas overexpression of PlexinD1 in upper layer neurons resulted in misplacement of the cells in deep cortical layers. Together, these results indicate that PlexinD1 signalling controls the laminar position of heterotopically projecting CPNs by regulating their radial migration during neocortical development

Texte intégral

Résumé :

This thesis concerns dimensions and projections of sets that could be described as fractals. The background is applied problems regarding analysis of human tissue. One way to characterize such complicated structures is to estimate the dimension. The existence of different types of dimensions makes it important to know about their properties and relations to each other. Furthermore, since medical images often are constructed by x-ray, it is natural to study projections.

This thesis consists of an introduction and a summary, followed by three papers.

Paper I, Anders Nilsson, Dimensions and Projections: An Overview and Relevant Examples, 2006. Manuscript.

Paper II, Anders Nilsson and Peter Wingren, Homogeneity and Non-coincidence of Hausdorff- and Box Dimensions for Subsets of ℝn, 2006. Submitted.

Paper III, Anders Nilsson and Fredrik Georgsson, Projective Properties of Fractal Sets, 2006. To be published in Chaos, Solitons and Fractals.

The first paper is an overview of dimensions and projections, together with illustrative examples constructed by the author. Some of the most frequently used types of dimensions are defined, i.e. Hausdorff dimension, lower and upper box dimension, and packing dimension. Some of their properties are shown, and how they are related to each other. Furthermore, theoretical results concerning projections are presented, as well as a computer experiment involving projections and estimations of box dimension.

The second paper concerns sets for which different types of dimensions give different values. Given three arbitrary and different numbers in (0,n), a compact set in ℝn is constructed with these numbers as its Hausdorff dimension, lower box dimension and upper box dimension. Most important in this construction, is that the resulted set is homogeneous in the sense that these dimension properties also hold for every non-empty and relatively open subset.

The third paper is about sets in space and their projections onto planes. Connections between the dimensions of the orthogonal projections and the dimension of the original set are discussed, as well as the connection between orthogonal projection and the type of projection corresponding to realistic x-ray. It is shown that the estimated box dimension of the orthogonal projected set and the realistic projected set can, for all practical purposes, be considered equal.

Résumé :

Lors d’une projection thermique de zircone partiellement stabilisée de type Nanox (particules micrométrique faites de nanoparticules agglomérées), il est difficile de conserver la nanostructure. Cela ne peut être réalisé que lorsque les plus grosses particules sont fondues en périphérie alors que les plus petites le sont totalement formant un liant entre les parties infondues nanostructurées. C’est pourquoi les temps de résidence des particules projetées, le coefficient de transfert thermique entre le plasma et les particules, les profils de température du plasma et les vitesses d’impact des particules doivent être soigneusement contrôlées pour pouvoir obtenir des dépôts présentant une distribution bimodale de structures nano et micrométriques ainsi qu’une tenue mécanique adéquate. Des projections thermiques ont été effectuées au moyen de torches PT-F4 et Plazjet (tuyères Conique et Step). Les paramètres de fonctionnement ont été optimisés via modélisation du traitement thermique des particules et caractérisation (module de Weibull de la dureté, microscopie électronique et optique) des dépôts. Avec la torche PT-F4, la nanostructure ne représente au mieux que 20 % du volume des dépôts alors que la Plazjet équipée d’une tuyère conique permet d’atteindre 40 % de nanostructure avec une meilleure tenue mécanique
When spraying partially stabilized zirconia micrometric particles made of agglomerated nanoparticles (Nanox), it is difficult to keep the nanostructure. This can be achieved only if the big particles are melted only at their periphery while the small are completely melted to make the “cement” between the unmelted nanostrutured cores. Thus the residence time of the particle, the heat transfer coefficient between plasma and particles, the plasma temperatures and the particle impact velocity have to be carefully controlled to achieve coatings with bimodal distribution of nano and micrometric structures and a sufficient mechanical resistance. Spraying has been performed with PT-F4 and Plazjet (equipped with Conical or Step anode nozzle) torches. The working parameters have been optimized though modelling of the heat treatment of particles and characterization (hardness Weibull modulus and Scanning Electron Microscope or Optical Microscope) of coatings. With the PT-F4 torch the nanostructure represents at the best 20 % of the coating volume while with the Plazjet equipped with the conical nozzle nanostructure can reach 40 % with a better mechanical resistance than that obtained with the PT-F4 with 20 % nanostructure

Résumé :

Abstract Most statistical agencies consult with experts in some manner prior to formulating their assumptions about the future. Expert judgment is valuable when there is either a lack of good data, insufficient knowledge about underlying causal mechanisms, or apparent randomness in trends. In this paper, we describe the expert elicitation protocol developed by Statistics Canada in 2018 to inform the development of projection assumptions. The protocol may be useful for projection makers looking to adopt a formal approach to eliciting expert judgments, or for producing probabilistic projections, where it is necessary to obtain plausible estimates of uncertainty for components of population growth.

Résumé :

Abstract The well-known pictorial drafting technique of isometric drawing is here generalized in two ways, called “isoclinal” and “axial”, or collectively, “symmetric”. Although the isoclinal projection preserves the useful property of foreshortening adjacent edges equally, and the axial projection foreshortens adjacent edges equally, the directions for these projections usually differ from that for isometric projection. Formulas are derived for the isoclinal and axial directions and their foreshortening factors and rotation matrices. Although intended for three-dimensional computer-aided design, the symmetric projections can also be performed on a drawing board with a protractor. Graphic examples involving design of non-rectangular connectors for three skew structural members and adjacent plates in space are presented.

Résumé :

The Abel, onion-peeling, and filtered back-projection inversion methods can be inter-compared without assumptions about the object being deconvolved. If the projection data (such as optical absorption, beam deflection, or phase shift) are taken at equally spaced radial positions, the deconvolved field is given by weighted sums of the projections divided by the data spacing. The weighting factors are independent of the data spacing. All the methods are highly similar and have Abel-like behavior: the field at a radial location is primarily determined by the weighted differences of a few projections around that radial position. The weighting factors also determine the relative noise of each method. Based on ease of calculation, robustness, and noise, a three-point Abel inversion is preferred. This analysis also shows that the signal-to-noise ratios of the deconvolutions deteriorate if the projection data are taken too close together.

Résumé :

In the December 2022 Summary of Economic Projections (SEP), the median projection for four-quarter core PCE inflation in the fourth quarter of 2025 is 2.1 percent. This same SEP has unemployment rising by nine-tenths, to 4.6 percent, by the end of 2023. We assess the plausibility of this projection using a specific nonlinear model that embeds an empirically successful nonlinear Phillips curve specification into a structural model, identifying it via an underutilized data-dependent method. We model core PCE inflation using three components that align with those noted by Chair Powell in his December 14, 2022, press conference: housing, core goods, and core-services-less-housing. Our model projects that conditional on the SEP unemployment rate path and a rapid deceleration of core goods prices, core PCE inflation moderates to only 2.75 percent by the end of 2025: inflation will be higher for longer. A deep recession would be necessary to achieve the SEP’s projected inflation path. A simple reduced-form welfare analysis, which abstracts from any danger of inflation expectations becoming unanchored, suggests that such a recession would not be optimal.

Résumé :

This paper presents a first approximation to assess the impact of the COVID-19 outbreak on Argentinas pension system in both the short and medium/long-term. To this end, we have used the Pension Projection Model of the Inter-American Development Bank (IDB) to design and analyze possible scenarios and outcomes, based on alternative scenarios. According to the data analyzed and the projections, the impact of COVID-19 on Argentinas pension system in the short run seems to have been limited, particularly given the rapid recovery during the last months of 2021. The long-term impact is harder to predict. Given the macroeconomic effects of the efforts made by authorities to protect the system and pensioners during the pandemic on the one hand; and the effects of COVID-19 within the labor market on the other, overall consequences are still to be fully understood.
