Warm Absorbers in Active Galactic Nuclei [PDF]

open access: yesarXiv, 2000
We first provide a review of the properties of warm absorbers concentrating on what we have learned from ROSAT and ASCA. This includes dusty and dust-free warm absorbers, non-X-ray emission and absorption features of warm absorbers, and the possible warm absorber interpretation of the peculiar 1.1 keV features.

A material model for aluminium sheet forming at elevated temperatures [PDF]

open access: yes, 2001
In order to accurately simulate the deep drawing or stretching of aluminum sheet at elevated\ud temperatures, a model is required that incorporates the temperature and strain-rate dependency of the material.\ud In this paper two models are compared: a ...

Differentiable Drawing and Sketching [PDF]

open access: yesarXiv, 2021
We present a bottom-up differentiable relaxation of the process of drawing points, lines and curves into a pixel raster. Our approach arises from the observation that rasterising a pixel in an image given parameters of a primitive can be reformulated in terms of the primitive's distance transform, and then relaxed to allow the primitive's parameters to

Aluminium sheet forming at elevated temperatures [PDF]

open access: yes, 2001
The formability of aluminum sheet depends on the temperature of the material and the strain\ud rate. E.g. the limiting drawing ratio can be improved by increasing the temperature uniformly, but even more by\ud heating the flange and cooling the punch. To

3D Sketching using Multi-View Deep Volumetric Prediction [PDF]

open access: yes, 2017
Sketch-based modeling strives to bring the ease and immediacy of drawing to the 3D world. However, while drawings are easy for humans to create, they are very challenging for computers to interpret due to their sparsity and ambiguity. We propose a data-driven approach that tackles this challenge by learning to reconstruct 3D shapes from one or more ...

The upper bound on the lowest mass halo [PDF]

open access: yes, 2016
We explore the connection between galaxies and dark matter halos in the Milky Way (MW) and quantify the implications on properties of the dark matter particle and the phenomenology of low-mass galaxy formation. This is done through a probabilistic comparison of the luminosity function of MW dwarf satellite galaxies to models based on two suites of zoom-

Advanced Knowledge Extraction of Physical Design Drawings, Translation and conversion to CAD formats using Deep Learning [PDF]

open access: yes
The maintenance, archiving and usage of the design drawings is cumbersome in physical form in different industries for longer period. It is hard to extract information by simple scanning of drawing sheets. Converting them to their digital formats such as Computer-Aided Design (CAD), with needed knowledge extraction can solve this problem.

Exploring the Dust Content of Galactic Winds With Herschel. II. Nearby Dwarf Galaxies [PDF]

open access: yes, 2018
We present the results from an analysis of deep Herschel Space Observatory observations of six nearby dwarf galaxies known to host galactic-scale winds. The superior far-infrared sensitivity and angular resolution of Herschel have allowed detection of cold circumgalactic dust features beyond the stellar components of the host galaxies traced by Spitzer

The influence of the visual elements of cover design on the appeal of art and cultural magazines: case study is book fare in Oulu [PDF]

open access: yes, 2015
Design of magazines - a complex and time-consuming process, often requiring custom solutions. Developers need to know what impact on the visual component of information influence on the audience.
