Abstract: A vehicle-mounted hydrogen supply method and device for hydrogen-rich smelting in a blast furnace or shaft furnace, combining steel plant hydrogen supply requirements with vehicle-mounted hydrogen supply technologies to construct a vehicle-mounted hydrogen supply system applied to hydrogen-rich smelting in a blast furnace or shaft furnace, thus providing an effective and reliable pathway for safe and stable hydrogen supply in a blast furnace or shaft furnace smelting process to perform hydrogen-rich smelting testing and production. Compared with a newly-built hydrogen plant, the invested construction cost is low, the operation flow is simple, the method and device are not limited by technical upgrading and transformation, and the flexibility is high. At the same time, two working long pipe vehicles and two pressure reducing system intake pipelines are used for solving the problem of continuous hydrogen supply required for hydrogen-rich smelting in a blast furnace.

Abstract: The present disclosure relates to systems, methods, and computer readable media for predicting surplus capacity on a set of server nodes and determining a quantity of deferrable virtual machines (VMs) that may be scheduled over an upcoming period of time. This determination of VM quantity may be determined while minimizing risks associated with allocation failures on the set of server nodes. This disclosure described systems that facilitate features and functionality related to improving utilization of surplus resource capacity on a plurality of server nodes by implementing VMs having some flexibility in timing of deployment while also avoiding significant risk caused as a result of over-allocated storage and computing resources. In one or more embodiments, the quantity of deferrable VMs is determined and scheduled in accordance with rules of a scheduling policy.

Abstract: A system and method is provided that includes acquiring chemical exchange saturation transfer (CEST) data with the MRI system and generating an acquired Z-spectrum (Z) from the CEST data. The system and method also includes computing an estimated direct water saturation (Z?) based using at least one of relaxation measurements derived from the CEST data or imaging parameters used to acquire the CEST data with the MRI system, computing a direct saturation corrected Z-spectrum (?Z) using the acquired Z-spectrum (Z) and the estimated direct water saturation (Z?), and generating a CEST image of the subject using the direct saturation corrected Z-spectrum (?Z).

Abstract: The present disclosure relates to systems and methods for determining quantitative chemical exchange or exchangeable proton information from a region-of-interest in a subject. The methods and systems use adaptive fitting to quantify magnetic resonance (MR) data, such as chemical exchange saturation transfer magnetic resonance imaging (CEST MRI) images, using initial values based on, for example, Lorentzian fitting. Images are iteratively less downsampled until quantitative maps of desired resolution are obtained. Such an approach allows for reliable fitting at a faster fitting speed, and is less susceptible to suboptimal signal to noise (SNR) than conventional methods.

Abstract: The present laser barcode scanner employs (i) a simplified scan mechanism made from a semi-flexible substrate that eliminates complicated optical assemblies, (ii) a layout with location features eliminating the need for special alignment, and (iii) a layout with all surface mounted devices on a single layer eliminating the need for extra soldering. Together these strategies, when used with a method of mitigating stray-light by separating light paths with a circuit board, combine to achieve a laser barcode scanner of unique simplicity and performance.
