Abstract:
We consider applications involving a large set of instances of projecting points to polytopes. We develop an intuition guided by theoretical and empirical analysis to show that when these instances follow certain structures, a large majority of the projections lie on vertices of the polytopes. To do these projections efficiently we derive a vertex-oriented incremental algorithm to project a point onto any arbitrary polytope, as well as give specific algorithms to cater to simplex projection and polytopes where the unit box is cut by planes. Such settings are especially useful in web-scale applications such as optimal matching or allocation problems. Several such problems in internet marketplaces (e-commerce, ride-sharing, food delivery, professional services, advertising, etc.), can be formulated as Linear Programs (LP) with such polytope constraints that require a projection step in the overall optimization process. We show that in some of the very recent works, the polytopic projection is the most expensive step and our efficient projection algorithms help in gaining massive improvements in performance.

Abstract:
Continuous Time Echo State Networks (CTESNs) are a promising yet under-explored surrogate modeling technique for dynamical systems, particularly those governed by stiff Ordinary Differential Equations (ODEs). A key determinant of the generalization accuracy of a CTESN surrogate is the method of projecting the reservoir state to the output. This paper shows that of the two common projection methods (linear and nonlinear), the surrogates developed via the nonlinear projection consistently outperform those developed via the linear method. CTESN surrogates are developed for several challenging benchmark cases governed by stiff ODEs, and for each case, the performance of the linear and nonlinear projections is compared. The results of this paper demonstrate the applicability of CTESNs to a variety of problems while serving as a reference for important algorithmic and hyper-parameter choices for CTESNs.

Abstract:
AbstractMathematical methods take an important part in reconstruction technologies of radiographic image. Back projection, iterative, and analytical (Two-dimensional Fourier, Filtered Back Projection) methods are the most important procedures for image reconstruction. Whenever there exists numerous projections, analytical methods have a great performance in speed and accuracy and due to these advantages they are comprehensively used for X-ray imaging. One of the widespread used methods in tomographic image reconstruction is Filtered Back Projection (FBP) algorithm. This paper presents an application of this reconstruction algorithm for a generated image of the object. Shepp-Logan filter is used to form the filtered back projection image and performance improvement is investigated. The obtained images indicate that FBP algorithm can be substantial for various applications in the field of medicine and industry.

Abstract:
In multi-beam satellite systems, Inter-Beam Interference (IBI) has a great effect on system performance. Within range of satellite coverage area, inclined projective multiple beams give rise to elliptic beam projections, resulting in that the distribution of beam projections is different from traditional cellular distribution. In this paper, an Inclined Projection (IP) model is proposed for IBI in OFDMA based GEO satellite communication systems, and corresponding analysis is also included. A comparison of carrier to interference power ratio (C/I) of users at the center of each cell with and without the consideration of IP is made, based on the simulation using different Frequency Reuse (FR) factor. The corresponding conclusions are presented. This research can provide reference for later satellite beam planning.

Abstract:
Abstract Using the Palmer drought severity index, the ability of 19 state-of-the-art climate models to reproduce observed statistics of drought over North America is examined. It is found that correction of substantial biases in the models’ surface air temperature and precipitation fields is necessary. However, even after a bias correction, there are significant differences in the models’ ability to reproduce observations. Using metrics based on the ability to reproduce observed temporal and spatial patterns of drought, the relationship between model performance in simulating present-day drought characteristics and their differences in projections of future drought changes is investigated. It is found that all models project increases in future drought frequency and severity. However, using the metrics presented here to increase confidence in the multimodel projection is complicated by a correlation between models’ drought metric skill and climate sensitivity. The effect of this sampling error can be removed by changing how the projection is presented, from a projection based on a specific time interval to a projection based on a specified temperature change. This modified class of projections has reduced intermodel uncertainty and could be suitable for a wide range of climate change impacts projections.

Abstract:
With the rapid development of virtual reality, omnidirectional images (ODIs) have attracted much attention from both the industrial community and academia. However, due to storage and transmission limitations, the resolution of current ODIs is often insufficient to provide an immersive virtual reality experience. Previous approaches address this issue using conventional 2D super-resolution techniques on equirectangular projection without exploiting the unique geometric properties of ODIs. In particular, the equirectangular projection (ERP) provides a complete field-of-view but introduces significant distortion, while the cubemap projection (CMP) can reduce distortion yet has a limited field-of-view. In this paper, we present a novel Bi-Projection Omnidirectional Image Super-Resolution (BPOSR) network to take advantage of the geometric properties of the above two projections. Then, we design two tailored attention methods for these projections: Horizontal Striped Transformer Block (HSTB) for ERP and Perspective Shift Transformer Block (PSTB) for CMP. Furthermore, we propose a fusion module to make these projections complement each other. Extensive experiments demonstrate that BPOSR achieves state-of-the-art performance on omnidirectional image super-resolution. The code is available at https://github.com/W-JG/BPOSR.

Abstract:
The advancement of deep convolutional neural networks (DCNNs) has driven significant improvement in the accuracy of recognition systems for many computer vision tasks. However, their practical applications are often restricted in resource-constrained environments. In this paper, we introduce projection convolutional neural networks (PCNNs) with a discrete back propagation via projection (DBPP) to improve the performance of binarized neural networks (BNNs). The contributions of our paper include: 1) for the first time, the projection function is exploited to efficiently solve the discrete back propagation problem, which leads to a new highly compressed CNNs (termed PCNNs); 2) by exploiting multiple projections, we learn a set of diverse quantized kernels that compress the full-precision kernels in a more efficient way than those proposed previously; 3) PCNNs achieve the best classification performance compared to other state-ofthe-art BNNs on the ImageNet and CIFAR datasets.

Abstract:
This study compares the performance of five popular equal-area projections supported by Free and Open Source Software for Geo-spatial (FOSS4G)—Sinusoidal, Mollweide, Hammer, Eckert IV and Homolosine. A set of 21,872 discrete distortion vindicatrices were positioned on the ellipsoid surface, centred on the cells of a Snyder icosahedral equal-area grid. These indicatrices were projected on the plane and the resulting angular and distance distortions computed, all using FOSS4G. The Homolosine is the only projection that manages to minimise angular and distance distortions simultaneously. It yields the lowest distortions among this set of projections and clearly outclasses when only land masses are considered. These results also indicate the Sinusoidal and Hammer projections to be largely outdated, imposing too large distortions to be useful. In contrast, the Mollweide and Eckert IV projections present trade-offs between visual expression and accuracy that are worth considering. However, for the purposes of storing and analysing big spatial data with FOSS4G the superior performance of the Homolosine projection makes its choice difficult to avoid.

Abstract:
La science d’aujourd’hui utilise de plus en plus la simulation pour modéliser et comprendre le monde qui nous entoure. Pour permettre à celles-ci d’être plus rapides, précises et modélisant de plus grand phénomènes, les scientifiques utilisent des supercalculateurs, domaine d’expertise du Calcul Haute-Performance. Or, à mesure que la demande en puissance de calcul grandit, ces machines se doivent d’être de plus en plus performantes. Seulement, la réduction de la taille des transistors prévue par la loi de Moore ne suffit plus à diriger l’évolution des processeurs, noyau de la puissance des supercalculateurs. Ainsi, pour continuer à être capable de répondre à cette demande, ces machines deviennent de plus en plus complexes. Et les performances des applications HPC dépendent des interactions entre les nombreux comportements des applications, les architectures des processeurs de plus en plus complexes et des choix faits par les différentes piles logicielle. Les efforts à fournir pour l’optimisation des performances des applications sur les machines sont donc de plus en plus importants. Une solution pour simplifier ces efforts d’optimisation et obtenir de meilleures performances des applications est de rassembler l’ensemble des acteurs du HPC dans un environnement de codesign pour la conception des futures machines. Ainsi, dans un tel environnement où les choix faits par les concepteurs sont dirigés par les intérêts des applications, les processeurs et la pile logicielle seront adaptés aux besoins des futurs utilisateurs. Cela est encore plus important depuis la récente arrivée de l’environnement Arm en HPC, représentant 10% de la puissance de calcul totale du Top500 avec seulement 6 machines. En effet, celui-ci offre une plus grande liberté aux constructeurs dans les choix des caractéristiques des processeurs. Seulement, dans un tel environnement de codesign, il est nécessaire d’utiliser une approche de prédiction de performance prenant en compte l’impact des choix faits par l’ensemble des acteurs pour pouvoir effectuer une exploration viable de l’espace de conception. Au cours de cette thèse, nous mettons en place une approche de projection de performance adaptée à notre définition d’un environnement de codesign regroupant les acteurs et les aspects des performances des applications en 3 groupes : l’application, la pile logicielle et le matériel. Ce modèle se présente en trois étapes pour effectuer la projection d’un triplet application/pile logicielle/matériel source, et accessible, vers un futur triplet cible d’intérêt, et inaccessible. Ces étapes sont : la caractérisation des performances sur nos trois aspects, suivi de l’analyse des performances sur le triplet source qui va enfin conduire à une projection des performances vers le triplet cible en fonction des différences entre les paramètres de celui-ci et du triplet source. Cette approche est ensuite implémentée à l’aide d’une représentation fondée sur le modèle Roofline dans laquelle on se concentre sur le maximum de performance atteignable par les triplets et on projette les performances avec une hypothèse de conservation de l’efficacité architecturale. Nous utilisons ensuite ce modèle pour l’analyse et l’exploration de paramètres matériels tels que la taille des vecteurs ou le choix du type de mémoire sur différentes architectures de coeurs Arm. Enfin, nous étendons cette exploration à des architectures multicoeurs en affinant la caractérisation de la bande passante et le travail effectués par chaque coeur. L’utilisation de cette approche se concentre sur l’exploration de paramètres applicatifs et de pile logicielle sur une future architecture d’intérêt pour le HPC : le processeur EPI (pour European Processor Initiative)
Today’s science increasingly uses simulation to model and understand the world around us. To improve their speed, accuracy, and modeling capabilities, scientists rely on supercomputers, the domain of expertise of High-Performance Computing. As the demand for computing power keeps growing, these machines must become ever more powerful. However, the reduction in transistor size predicted by Moore’s Law is no longer sufficient to drive the evolution of processors, the core of supercomputer power. Hence, these machines are becoming increasingly complex to answer this increasing demand. The performance of HPC applications depends on interactions between varied application behavior, a complex processor architecture, and the choices made by the software stack. As a result, optimizing applications’ performance on these machines is a tedious task. One solution to simplify optimization efforts and improve applications’ performance is to bring together all HPC actors in a codesign environment for designing future machines. In an environment where the interests of applications drive the choices made by constructors, the processors and software stack will be adapted to the needs of future users. It is all the more vital with the recent arrival of the Arm environment in HPC, already representing 10% total computing power of the Top500 with just six machines, because this environment offers manufacturers great freedom in their choice of processor characteristics. However, in such a codesign environment, it is mandatory to use a performance prediction approach that accounts for the impact of the choices made by all players to drive the design-space exploration. In this thesis, we implement a performance projection approach adapted to our definition of a codesign environment that groups the actors and aspects of application performance into three groups: the application, the software stack, and the hardware. This model takes the form of a three-step process for projecting an accessible application/software stack/source hardware triplet onto a future target triplet of interest, which is inaccessible. These steps are performance characterization of our three aspects, followed by performance analysis on the source triplet, which finally leads to a projection of performance towards the target triplet as a function of the differences between its parameters and those of the source triplet. Then, we implement this approach using a Roofline model representation, in which we focus on the maximum performance attainable by the triplets and project performance with an assumption of architectural efficiency conservation. We then use this model to analyze and explore hardware parameters such as hardware vector size and choice of memory type on different Arm core architectures. Finally, we extend this exploration to multi-core architectures by refining the characterization of the bandwidth and the workload of each core. Then, we use this extension for the exploration of application and software stack parameters on a future HPC architecture of interest: the EPI (European Processor Initiative) processor

Abstract:
The objectives of this thesis are threefold. First, this dissertation examines whether patterns (growth and consistency in growth) of firms' past financial performance influence investors' perceptions about stock values and future performance of these firms. Second, multiple estimation horizons of past performance variables (ranging from one to five years) are used to assess whether the interaction between growth patterns and measurement interval lengths of these variables influence investor expectations. Third, this thesis examines whether an intermediate price drifts (e.g. Jegadeesh and Titman [1993]) and subsequent long-horizon price reversal (e.g. DeBondt and Thaler (1985)] are manifestations of a market over-reaction as suggested in recent studies (e.g. Lee and Swaminathail [2000]).Annual data on sales, earnings, cash flow, and stock returns over various time periods from a sample of publicly traded firms listed on the NYSE, AMEX, and NASDAQ exchanges from 1983 to 1999 are used to address the research questions proposed in this thesis. The evidence provided in this study shows that low-growth firms outperform their high-growth firm counterparts across different performance variables, estimation intervals, and investment horizons except in the first post-formation year for firms ranked by their prior one-year financial growth rate (except for sales growth). These return differentials between low and high growth firms increase uniformly as more years of past financial performance added.Furthermore, when ranking firms based on the consistency of their prior financial growth rates over multiple estimation periods, this study finds that a firm consistently achieving low (high) growth rates that places it in the lowest (highest) growth 40 percent earns high (low) stock returns. The consistency in a firm's prior financial performance influences the behavior of its future stock returns, i.e. the longer the consistency of exceptionally strong (weak) performance of a firm, the greater (lower) its subsequent stock returns. However, the incremental impact of an additional year of growth consistency on future returns seems to dissipate after the third year of prior performance data, suggesting that it may not take investors longer than three years to assume that a firm's past growth will continue for many years to come. Thus, additional evidence confirming investors' prior beliefs will not lead to a significant price drift because their expectations are already reflected in market prices.First year returns for firms except SG exhibit a strong financial drift. The price drift seems to persist even with longer estimation horizons. Multiple regression analyses suggest that reported higher returns for low-growth firms is not due to risk as measured by market betas or book-to-market ratios, nor is it due to the disproportionate impact caused by relatively smaller firms. As well, the one-year-ahead size-adjusted abnormal returns are significantly and negatively related to the size-adjusted abnormal returns for years 2 through 5. This result indicates that the evidence of a price drift reported in the first post-formation year might be due to a market over-reaction, a finding consistent with results reported by Lee and Swaminathan (2000). In additional analysis, return performance for all growth portfolios for the month of January is compared to the remainder of the year. No evidence indicating that returns to these portfolios are driven by extraordinary performance of low-growth firms in the month of January.For all variables (except for past sales growth and to some degree past stock returns), the financial drift in year one return for portfolios based on prior-one year of past performance data, is significantly stronger than that reported in Chan et al. (2004). Results reported in this thesis indicate that the average abnormal return differential between low and high growth firms for the five-year estimation intervals (with exception of past sales growth) is greater than 10 percentage points. The evidence contradicts that documented in Chan et al. (2004). They find no discernable evidence of price reversals over the next 36-months after ranking firms by their five-year growth rates in sales, operating income, and net income. However, results of this study are consistent with the predictions of behavioral models (e.g. Daniel et al. [I998] and Lakonishok et al. [1994]) suggesting that investors put excessive weight on patterns of a firm's past financial performance when projecting its future prospects.

Abstract:
The finite state projection algorithm provides modelers a new way of directly solving the chemical master equation. The algorithm utilizes the matrix exponential function, and so the algorithm’s performance suffers when it is applied to large problems. Other work has been done to reduce the size of the exponentiation through mathematical simplifications, but efficiently exponentiating a large matrix has not been explored. This work explores implementing the finite state projection algorithm on several different high-performance computing platforms as a means of efficiently calculating the matrix exponential function for large systems. This work finds that general purpose graphics processing can accelerate the finite state projection algorithm by several orders of magnitude. Specific biological models and modeling techniques are discussed as a demonstration of the algorithm implemented on a general purpose graphics processor. The results of this work show that general purpose graphics processing will be a key factor in modeling more complex biological systems.

Abstract:
The aggressive scaling of silicon (Si) based complementary metal-oxide-semiconductor (CMOS) transistor over the past 50 years has resulted in an exponential increase in device density, which consequentially has increased computation power rapidly. This has pronounced the necessity to scale the device's supply voltage (VDD) in to order to maintain low-power device operation. However, the scaling of VDD can degrade drive current significantly due to the low carrier mobility of Si. To overcome the key challenges of dimensional and voltage scaling required for low-power electronic operation without degradation of device characteristics, the adoption of alternate channel materials with low bandgap with superior transport properties will play a crucial role to improve the computation ability of the standard integrated circuit (IC). The requirement of high-mobility channel materials allows the industry to harness the potential of III-V semiconductors and germanium. However, the adoption of such high mobility materials as bulk substrates remains cost-prohibitive even today. Hence, another key challenge lies in the heterogeneous integration of epitaxial high-mobility channel materials on the established cost-effective Si platform. Furthermore, dimensional scaling of the device has led to a change in architecture from the conventional planar MOSFET to be modified to a 3-D Tri-gate architecture which provides fully depleted characteristics by increasing the inversion layer area and hence, providing superior electrostatic control of the device channel to address short channel effects such as subthreshold slope (SS) and drain induced barrier lowering (DIBL). The Tri-gate configuration provides a steeper SS effectively reducing leakage current (IOFF), thereby decreasing dynamic power consumption and increasing device performance. Recently, Tantalum silicate (TaSiOx) a high-k dielectric has been shown to exhibit superior interfacial quality on multiple III-V materials. However, there is still ambiguity as to the potential of short-channel devices incorporating alternate channel (III-V) materials which is the basis of this research, to demonstrate the feasibility of future high-mobility n-channel InGaAs material integration on Si for high- speed, low-power, high performance CMOS logic applications.

Ces travaux se concentrent sur la résolution de problèmes de mécanique des fluides compressibles. De nombreuses méthodes numériques ont depuis plusieurs décennies été développées pour traiter ce type de problèmes. Cependant, l'évolution et la complexité des architectures informatiques nous poussent à actualiser et repenser ces méthodes numériques afin d'utiliser efficacement les calculateurs massivement parallèles. Au moyen de modèles de performance, nous analysons une méthode numérique de référence de type Lagrange-Projection afin de comprendre son comportement sur les supercalculateurs récents et d'en optimiser l'implémentation pour ces architectures. Grâce au bilan de cet analyse, nous proposons une formulation alternative de la phase de projection ainsi qu'une nouvelle méthode numérique plus performante baptisée Lagrange-Flux. Les développements de cette méthode ont permis d'obtenir des résultats d'une précision comparable à la méthode de référence
This works are dedicated to hydrodynamics. For decades, numerous numerical methods has been developed to deal with this type of problems. However, both the evolution and the complexity of computing make us rethink or redesign our numerical solver in order to use efficiently massively parallel computers. Using performance modeling, we perform an analysis of a reference Lagrange-Remap solver in order to deeply understand its behavior on current supercomputer and to optimize its implementation. Thanks to the conclusions of this analysis, we derive a new numerical solver which by design has a better performance. We call it the Lagrange-Flux solver. The accuracy obtained with this solver is similar to the reference one. The derivation of this method also leads to rethink the Remap step

Abstract:
Multilayer x-ray optics are becoming increasingly important in diverse applications such as x-ray projection lithography1, x-ray laser cavities2, x-ray microscopy3, astronomy4 and spectroscopy5. In this paper we focus on the current development of normal incidence reflective optics for the soft x-ray spectrum of ~45 - 130 Å. The ultimate goal is to develop a soft x-ray imaging system capable of high throughput and diffraction-limited performance over an appropriate image field.

Abstract:
One of the most important requirements for soft x-ray optics is high normal incidence reflectivity. But to ensure a high throughput optical system, Schwarzchild objectives in particular, it is not only necessary to fabricate multilayer coatings with the highest possible reflectivity but to achieve the designed d-spacing uniformity/grading and match the d-spacings of the concave and convex mirrors. The latter is especially important for high throughput multi-mirror lithography optical schemes.[1]

Abstract:
The design aspects of candidate reflective optical systems for projection lithography using extreme-ultraviolet (XUV) exposure wavelengths from approximately 10 to 20 nm have been discussed by various authors.1-3 The very demanding requirements for XUV-projection systems include the ability to resolve 0.1-μm features over at least a 25 mm x 25 mm image field with less than 0.01-μm distortion while providing a minimum of 1-μm total depth of focus. Other practical considerations affecting system imaging capability include thermal distortion of the mirror surfaces due to absorption of a fraction of the incident radiation beam and alignment tolerances. We present our analyses of the magnitude of these latter two effects on two types of reflective projection optical designs. We use the usual criteria for manufacturing and alignment errors4 and Zernike polynomials5 to represent the thermal and other distortions induced by the incident flux. We find that concentric, symmetric two-mirror systems2 are significantly less sensitive to thermal and alignment errors than off-axis, four-mirror systems.

Abstract:
Because multilayer x-ray structures are bandpass reflectors, the variation in multilayer period across the surfaces of near normal-incidence soft x-ray focussing optics has implications for performance of imaging systems. We have investigated these issues as they relate to Schwarzschild objectives coated with Mo/Si multilayers for use at wavelengths ranging from roughly 12.4 to 21.0 nm. The results can be generalized to other types of compound reflective imaging or projection systems and wavelength ranges.

Abstract:
Projection x-ray lithography has been proposed as a possible candidate for the delineation of integrated circuit features below 0.25µm (1). Recently it was demonstrated that near diffraction limited imaging could be achieved at several soft x-ray wavelengths (2) (3). Using 0.06pm thick films of PMMA, features of 0.2µm nd 0.1µm were printed at 37.5 and 14nm respectively. Figure 1 shows a scanning electron micrograph of these features. Note that the resist sidewalls exposed at 14nm are significantly more vertical than those printed at 37.5nm. The purpose of this work is to investigate the reasons for this difference by developing a simulation tool that would accurately model resist profiles in the soft x-ray regime (5 to 40nm).

Abstract:
The rapid development of high average power excimer lasers pushes the potential of a laser plasma x-ray source for SXPL. Now that the problem of debris production is solved at least at the prototype level [1] the source might be a candidate for operation in an industrial environment. The development of high reflectivity multilayer coatings for soft x-rays at normal incidence makes it possible to produce a demagnifying x-ray optical system. Together with an x-ray reflection mask all ingredients to develop a SXPL system are present. A cooperation of research institutes, semiconductor industry, resist and laser manufacturers has been set up to develop the process technology required.

Abstract:
We discuss the performance requirements for reflective imaging systems which will be needed to obtain ~0.1-μn resolution via projection lithography in the extreme-ultraviolet (XUV) wavelength region ≤100 nm. Designs are considered that use centered, non-tilted, annular optical elements. The inter-relationships between the illumination system, degree of spatial coherence, and the reduction system are evaluated, and the tradeoffs in performance for the total system between using an optimized annular illumination system and full illumination are analyzed. It will be shown that for our designs, annular illumination with XUV wavelengths does not significantly improve system performance. This result simplifies the illumination system design.

Abstract:
In this report, we have evaluated the performance of nearly 40 global climate models (GCMs) participating in Phase 6 of the Coupled Model Intercomparison Project (CMIP6). The focus is on the northern European area, but the ability to simulate southern European and global climate is discussed as well. Model evaluation was started with a technical control; completely unrealistic values in the GCM output files were identified by seeking the absolute minimum and maximum values. In this stage, one GCM was rejected totally, and furthermore individual output files from two other GCMs. In evaluating the remaining GCMs, the primary tool was the Model Climate Performance Index (MCPI) that combines RMS errors calculated for the different climate variables into one index. The index takes into account both the seasonal and spatial variations in climatological means. Here, MCPI was calculated for the period 1981—2010 by comparing GCM output with the ERA-Interim reanalyses. Climate variables explored in the evaluation were the surface air temperature, precipitation, sea level air pressure and incoming solar radiation at the surface. Besides MCPI, we studied RMS errors in the seasonal course of the spatial means by examining each climate variable separately. Furthermore, the evaluation procedure considered model performance in simulating past trends in the global-mean temperature, the compatibility of future responses to different greenhouse-gas scenarios and the number of available scenario runs. Daily minimum and maximum temperatures were likewise explored in a qualitative sense, but owing to the non-existence of data from multiple GCMs, these variables were not incorporated in the quantitative validation. Four of the 37 GCMs that had passed the initial technical check were regarded as wholly unusable for scenario calculations: in two GCMs the responses to the different greenhouse gas scenarios were contradictory and in two other GCMs data were missing from one of the four key climate variables. Moreover, to reduce inter-GCM dependencies, no more than two variants of any individual GCM were included; this led to an abandonment of one GCM. The remaining 32 GCMs were divided into three quality classes according to the assessed performance. The users of model data can utilize this grading to select a subset of GCMs to be used in elaborating climate projections for Finland or adjacent areas. Annual-mean temperature and precipitation projections for Finland proved to be nearly identical regardless of whether they were derived from the entire ensemble or by ignoring models that had obtained the lowest scores. Solar radiation projections were somewhat more sensitive.
