C’est le contraire de la superficialité, de la vacuité. Cette image convient parfaitement à la francophonie canadienne. Cette dernière n’est-elle pas fermement ancrée, fixée dans l’espace canadien ?

Abstract:
A polychromatic X-ray beam causes the grey of the reconstructed image to depend on its position within a solid and the material being imaged. This factor makes quantitative measurements via computed tomography (CT) imaging very difficult. To obtain a narrow-energy-width reconstructed image, we propose a model to decompose multivoltage X-ray images into many narrow-energy-width X-ray images by utilizing the low frequency characteristics of X-ray scattering. It needs no change of hardware in the typical CT system. Solving the decomposition model, narrow-energy-width projections are obtained and

Abstract:
The paper is proposing a method of image segmentation applied to the study of the micrographs of cellular solids. The segmentation is based on a thresholding which creates a binary (black and white) image of the micrograph. The binary image is divided in super-pixels which correspond to the microcells of the material. From the areas of the super-pixels it is easy to evaluate the distribution of the size of the cells and correlate this distribution to the properties of the material.Read Complete Article at ijSciences: V62017021201 AND DOI: http://dx.doi.org/10.18483/ijSci.1201

AbstractBased on a scanning electron microscope operated at 30 kV with a homemade specimen holder and a multiangle solid-state detector behind the sample, low-kV scanning transmission electron microscopy (STEM) is presented with subsequent electron tomography for three-dimensional (3D) volume structure. Because of the low acceleration voltage, the stronger electron-atom scattering leads to a stronger contrast in the resulting image than standard TEM, especially for light elements. Furthermore, the low-kV STEM yields less radiation damage to the specimen, hence the structure can be preserved. I

Amplification of low-light-level optical images is important for extending the range of lidar systems that image and detect objects in the atmosphere and underwater. The use of range-gating to produce images of particular range bins is also important in minimizing the image degradation due to light that is scattered backward from aerosols, smoke, or water along the imaging path. For practical lidar systems that must be operated within sight of unprotected observers, eye safety is of the utmost importance.

View synthesis allows the generation of new views of a scene given one or more images. Current methods rely on multiple input images, which are practically not feasible for such applications. While using a single image to create a 3D scene is difficult since it necessitates a solid understanding of 3D settings. To facilitate this, a complete scene understanding of a single-view image is performed using spatial feature extraction and depth map prediction.

Abstract:
We address the problem of object co-segmentation in images. Object co-segmentation aims to segment common objects in images and has promising applications in AI agents. We solve it by proposing a co-occurrence map, which measures how likely an image region belongs to an object and also appears in other images. The co-occurrence map of an image is calculated by combining two parts: objectness scores of image regions and similarity evidences from object proposals across images. We introduce a deep-dense conditional random field framework to infer co-occurrence maps. Both similarity metric and ob

Abstract:
Abstract This paper illustrates the application of pore-scale numerical simulation to evaluate permeability changes due to solids precipitation with Digital Rock Physics (DRP). A DRP modeling workflow is used to quantify permeability changes due to solid phase formation (precipitation of gas hydrates) based on their deposition morphology on the pore scale. Virtual representations of a sandstone sample from the Bentheimer outcrop are created using micro-computer-tomography (micro-CT) scanning images and state-of-the-art segmentation algorithms. The binarized images (pores and grains) are system

Abstract:
Jimmie Åkesson and his party, the Sweden Democrats (SD), are not yet authentically democratic. They are still “the same old iron gang as usual” despite concerted efforts to change their image. Of course, Åkesson has steered the SD away from the Nazi movement onto a more parliamentary path. But its essence – alarmist resistance to immigrants and Islamophobia – has remained the same, and there is still no solid indication that Åkesson has matured or moderated over the years.

The goal of a QIBA Profile is to help achieve a useful level of performance for a given biomarker. The Claim (Section 2) describes the biomarker performance. The Profile Activities (Section 3) contribute to generating the biomarker. Requirements are placed on the Actors that participate in those activities as necessary to achieve the Claim. Assessment Procedures (Section 4) defines the technical methods to be used for evaluating conformance with profile requirements. This includes the steps needed for clinical sites and equipment vendors to be compliant with the Profile. This QIBA Profile (Sma

Abstract:
Deep learning algorithms are a subset of machine learning algorithms that aim to explore several levels of the distributed representations from the input data. Recently, many deep learning algorithms have been proposed to solve traditional artificial intelligence problems. In this review paper, some of the up-to-date algorithms of this topic in the field of computer vision and image processing are reviewed. Following this, a brief overview of several different deep learning methods and their recent developments are discussed.

Abstract:
First arrivals are the primary waves picked and analyzed by seismologists to infer properties of the subsurface. Here we try to solve a problem in a small subsection of the seismic processing workflow: first break picking of seismic reflection data. We formulate this problem as an image segmentation task. Data is preprocessed, cleaned from outliers and extrapolated to make the training of deep learning models feasible. We use Fully Convolutional Networks (specifically UNets) to train initial models and explore their performance with losses, layer depths, and the number of classes. We propose t

Abstract:
After Chinese authorities abruptly reversed the country’s zero-COVID policy in 2022, global policymakers needed a clear and timely picture of the economic and health fallout. China’s economy is the world’s second largest and the country has deep global links, so an accurate picture of its trajectory mattered for global health, growth and inflation. Getting a solid read was a challenge, however, since official health and economic data not only were not timely, but were widely viewed as unreliable.

Abstract:
The emergence of artificial intelligence (AI) in the workplace has raised numerous questions. On the one hand, its ability to increase efficiency and relieve people of routine tasks is widely celebrated. On the other hand, there is growing concern about the role humans will play when machines not only execute tasks but also create, respond, and decide. In this new scenario, soft skills are often proposed as a possible answer—but not without significant challenges. In an environment where algorithms can already write texts, generate images, serve customers, and solve operational problems, it is

Abstract:
Scrubbers and separators are used in natural gas pipelines to remove solid and liquid materials from the gas stream. Failure to remove the entrained materials from the gas can result in equipment damage, increased pressure drop due to liquid accumulation, flow measurement errors, and corrosion. The performance of separators is rarely tested after a separator is installed because there is a lack of test instrumentation and it is difficult to conduct tests at the high pressures. The only indicators of poor separator performance are recurring problems in downstream equipment or the detection of a
