Visualizing Algorithms

Visualizing Algorithms
The power of the unaided mind is highly overrated… The real powers come from devising external aids that enhance cognitive abilities. —Donald Norman Algorithms are a fascinating use case for visualization. To visualize an algorithm, we don’t merely fit data to a chart; there is no primary dataset. But algorithms are also a reminder that visualization is more than a tool for finding patterns in data. #Sampling Before I can explain the first algorithm, I first need to explain the problem it addresses. Light — electromagnetic radiation — the light emanating from this screen, traveling through the air, focused by your lens and projected onto the retina — is a continuous signal. This reduction process is called sampling, and it is essential to vision. Sampling is made difficult by competing goals. Unfortunately, creating a Poisson-disc distribution is hard. You can see from these dots that best-candidate sampling produces a pleasing random distribution. Here’s how it works: Now here’s the code: Related:  Modélisationprogramming

L'agriculture croît dans les mathématiques Réduction des pesticides et engrais, prédiction des récoltes, adaptation au changement climatique... Les défis posés à l’agriculture sont multiples et les mathématiciens ont des solutions à apporter. Focus sur leurs travaux à l'occasion du Salon de l'agriculture qui se tient à la Porte de Versailles jusqu'au 3 mars. Peut-on mettre l’agriculture en équations ? Simulation de la croissance de plantes (betterave, Arabidopsis, blé, riz, maïs, tournesol, chrysanthème, concombre, tomate, poivron, caféier, pin) par le logiciel Digiplante du laboratoire de mathématiques et informatique de CentraleSupélec. Prédire la récolte grâce aux modèles Les semenciers qui mettent au point de nouvelles variétés tirent aussi un vrai bénéfice de ces modélisations, qui leur permettent d’optimiser leurs essais : sur cent essais d’une nouvelle variété réalisés en différents endroits de la planète, 20 seront effectivement conduits en conditions de culture, et le reste sera effectué par simulation.

Adidas and Stella McCartney launch new line to promote eco-friendly fashion - Climate Action Programme Adidas has revealed a new clothing line with Stella McCartney which aims to focus on the importance of protecting nature. In keeping with Adidas’s pledge to increase sustainability, the new AW18 line will include eco-friendly fabrics such as recycled polyester, organic cotton, and recycled ocean plastic. Stella McCartney said: “More than half of our apparel and a third of our footwear in AW18 are made with eco-innovative and recycled materials.” The line is designed to allow female athletes to exercise in any weather conditions. The clothing pieces will feature nature-inspired prints which act as a reminder to look after the world we live in. In addition, last week, Ms McCartney unveiled the new sustainably designed ‘Loop Sneakers’ on her Instagram page, which are also recyclable. Ming Xi, supermodel and global ambassador of Adidas by Stella McCartney, revealed “I am really inspired by the brands ambition to make a difference and its devotion to sustainability.”

Strawberry Perl for Windows Maimosine met le monde en modèles De l’exercice physique à la surchauffe des microprocesseurs, les mathématiciens de Maimosine, centre de modélisation et de simulation numérique, aident les chercheurs et industriels du bassin grenoblois à mieux comprendre certains phénomènes complexes. Le point commun entre un coureur en plein effort, une pièce qui vibre dans un moteur, de la glace de mer en train de se fragmenter ou des microprocesseurs qui surchauffent ? Ce sont tous des sujets d’étude pour les mathématiciens de la Maison de la modélisation et de la simulation, nanosciences et environnement (Maimosine). Créée à Grenoble en 2010 et juchée sur les hauteurs d’une tour dominant le campus universitaire, elle constitue un refuge pour les chercheurs et entreprises de la région lorsqu’un phénomène complexe leur échappe. « Modéliser, c’est mettre en équations un phénomène, le simplifier.

Vegan Designer Stella McCartney Edges Out Chanel and Louis Vuitton as Kindest Luxury Fashion Brand Vegan fashion brand Stella McCartney has been ranked number one in empathy, generosity, and kindness on the New York-based Luxury Institute’s annual “Emotionally Intelligent Brand Index.” McCartney, daughter of former Beatle Sir Paul McCartney and the late musician and entrepreneur Linda McCartney, edged out leading luxury brands including Chanel and Louis Vuitton in earning the top spot in those categories. The Luxury Institute’s ranking looks at how a brand relates to its customers, employees, and society at large, including its impact on the environment. Millennial Market “Today affluent consumers across all generations, but especially Millennials, think of brands as organic, living entities comprised of the purpose, values and behaviors of the people who lead them and who represent them at the front lines, across any channel,” says Milton Pedraza, CEO of the Luxury Institute. “A brand, today, is known well beyond its products.

Install Rust - Rust Programming Language Getting started If you're just getting started with Rust and would like a more detailed walk-through, see our getting started page. Windows considerations On Windows, Rust additionally requires the C++ build tools for Visual Studio 2013 or later. The easiest way to acquire the build tools is by installing Microsoft Visual C++ Build Tools 2019 which provides just the Visual C++ build tools. For further information about configuring Rust on Windows see the Windows-specific rustup documentation. Toolchain management with rustup Rust is installed and managed by the rustup tool. If you've installed rustup in the past, you can update your installation by running rustup update. For more information see the rustup documentation. Configuring the PATH environment variable In the Rust development environment, all tools are installed to the ~/.cargo/bin %USERPROFILE%\.cargo\bin directory, and this is where you will find the Rust toolchain, including rustc, cargo, and rustup.

Modéliser plus pour simuler moins À l’occasion du colloque « Modélisation : succès et limites », le chercheur Frédéric Alexandre nous éclaire sur les développements actuels de la simulation et de la modélisation. Frédéric Alexandre, vous êtes chercheur au Laboratoire bordelais de recherche en informatique (LaBRI1) et intervenant du colloque « Modélisation : succès et limites » qui se tient le 6 décembre 2016. Qu’entend-on au juste aujourd'hui par modélisation et simulation ? Visualisation issue de la simulation numérique des impacts de gouttelettes sur une surface liquide. En quoi cette démarche de modélisation-simulation a-t-elle bouleversé la façon de faire de la recherche dans certaines disciplines ? Ces quinze dernières années, les progrès des algorithmes ont autant contribué à l'accélération des calculs que la puissance des processeurs. On nous annonce depuis longtemps la fin de la loi de Moore relative à l'accroissement régulier de la puissance des ordinateurs.

Stella McCartney: Change Agent LONDON, United Kingdom — In a nondescript building tucked away on a quiet street in West London, Stella McCartney and her team are comparing the properties of a real leather shoe to the various non-leather swatches being considered for her brand’s Winter 2015 shoe collection. McCartney is wearing a cream blouse, open at the neck, with faded blue jeans and non-leather boots. Pinned up against the wall are boards labeled: “Heels,” “Mules,” and “Cutouts.” Women of differing ages, ethnicities and body types come in and out of the room with a constant flow of new ideas and creative references while McCartney acts as a kind of real-time editor, deciding what colours, materials and shapes feel right for the upcoming season. “That non-leather thing was doing a bit of a leather thing,” McCartney declares obscurely, at one point, caressing one of the samples and then draping it on top of her foot.
