The XANES energy region extends between the edge region and the EXAFS region over a 50-100 eV energy range around the core level x-ray absorption threshold. Before 1980 the XANES region was wrongly assigned to different final states: a) unoccupied total density of states, or b) unoccupied molecular orbitals (kossel structure) or c) unoccupied atomic orbitals or d) low energy EXAFS oscillations.
X-ray absorption (left) and differential phase-contrast (right) image of an in-ear headphone obtained with a grating interferometer at 60kVp. Phase-contrast X-ray imaging or phase-sensitive X-ray imaging is a general term for different technical methods that use information concerning changes in the phase of an X-ray beam that passes through an object in order to create its images.
The main limitation of this type of CT is the bulk and inertia of the equipment (X-ray tube assembly and detector array on the opposite side of the circle) which limits the speed at which the equipment can spin. Some designs use two X-ray sources and detector arrays offset by an angle, as a technique to improve temporal resolution. [8] [9]
Tinkerforge is an open source hardware platform of stackable microcontroller building blocks (Bricks) that can control different modules (Bricklets). The primary communication interface of the building blocks can be extended using Master Extensions. The hardware can be controlled by external programs written in C, C++, C#, Object Pascal, Java ...
The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. [5] [6] [7] The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; [8] the pattern of position detection was found and determined by applying the least-used ratio (1:1:3 ...
SourceForge is a web-based source code repository. It acts as a centralized location for free and open-source software projects. It was the first to offer this service for free to open-source projects. Project developers have access to centralized storage and tools for managing projects, though it is best known for providing revision control ...
A smithy built around 1880 in Mērsrags, Courland, Latvia currently located at The Ethnographic Open-Air Museum of Latvia. A forge is a type of hearth used for heating metals, or the workplace ( smithy) where such a hearth is located. The forge is used by the smith to heat a piece of metal to a temperature at which it becomes easier to shape by ...
The Titanic Museum is a two-story museum shaped like the RMS Titanic. It is located in Pigeon Forge, Tennessee, United States, and opened on April 8, 2010. It is built half-scale to the original ship. Similar to the one in Branson, Missouri, the museum holds 400 pre-discovery artifacts in twenty galleries. It is the largest permanent Titanic ...
