    ActiveSchematics AutoRendering Mobile Device Optimization

    In this modern era, technology is one of our main necessities. Technology is always evolving and changes from day by day. One of the major developments in technology is the increasing usage of mobile devices for personal use or even for company use. AA-AS/EDS-WIR2 is one of the sub departments in the Robert Bosch Company that creates applications for the automotive market. The department has created an application named ActiveSchematics AutoRendering. This application is used in car workshops to help mechanics to repair car defects by rendering the car schematics. This application is constructed with an ASP.NET framework combined with a standalone Delphi program as a plugin. The front-end development is done using HTML5, CSS, JavaScript code, and the back-end development is done using C#. The schematics are SVG-based with HTML as the container file. At present, the rendered schematics are not compatible when opened from a mobile browser, because the legacy support for interactivity (for example zooming and panning) is implemented without any mobile support code. The company wants the application to become a mobile device friendly application. The research proposal to be addressed is to solve which front-end libraries can be used to help the SVG schematics to implement mobile-based gesture compatibility. After some trial and error experiments, mobile device improvement will be implemented by adding jQuery, Hammer.js, jQuery PanZoom, and Bootstrap library. The experimental results have been successful and the company can have the mobile device friendly feature for their clients. This research shows that jQuery and hammer.js can be implemented on an SVG object to become a mobile device friendly schematic

    The Stability of Al11Sm3 (Al4Sm) Phases in the Al-Sm Binary System

    The relative stability of Al11Sm3 (Al4Sm) intermetallic phases was experimentally investigated through a series of heat treatments followed by microstructural, microchemical, and X-ray diffraction (XRD) analyses. The principal findings are that the high-temperature tetragonal phase is stable from 1655 to 1333 K and that the low-temperature orthorhombic phases, α and γ, have no range of full stability but are metastable with respect to the crystalline Al and Sm reference states down to 0 K. Thermodynamic modeling is used to describe the relative energetics of stable and metastable phases along with the associated two-phase mixtures. Issues regarding transition energetics and kinetics are discussed

    Chest radiograph classification and severity of suspected COVID-19 by different radiologist groups and attending clinicians: multi-reader, multi-case study.

    OBJECTIVES: To quantify reader agreement for the British Society of Thoracic Imaging (BSTI) diagnostic and severity classification for COVID-19 on chest radiographs (CXR), in particular agreement for an indeterminate CXR that could instigate CT imaging, from single and paired images. METHODS: Twenty readers (four groups of five individuals)-consultant chest (CCR), general consultant (GCR), and specialist registrar (RSR) radiologists, and infectious diseases clinicians (IDR)-assigned BSTI categories and severity in addition to modified Covid-Radiographic Assessment of Lung Edema Score (Covid-RALES), to 305 CXRs (129 paired; 2 time points) from 176 guideline-defined COVID-19 patients. Percentage agreement with a consensus of two chest radiologists was calculated for (1) categorisation to those needing CT (indeterminate) versus those that did not (classic/probable, non-COVID-19); (2) severity; and (3) severity change on paired CXRs using the two scoring systems. RESULTS: Agreement with consensus for the indeterminate category was low across all groups (28-37%). Agreement for other BSTI categories was highest for classic/probable for the other three reader groups (66-76%) compared to GCR (49%). Agreement for normal was similar across all radiologists (54-61%) but lower for IDR (31%). Agreement for a severe CXR was lower for GCR (65%), compared to the other three reader groups (84-95%). For all groups, agreement for changes across paired CXRs was modest. CONCLUSION: Agreement for the indeterminate BSTI COVID-19 CXR category is low, and generally moderate for the other BSTI categories and for severity change, suggesting that the test, rather than readers, is limited in utility for both deciding disposition and serial monitoring. KEY POINTS: • Across different reader groups, agreement for COVID-19 diagnostic categorisation on CXR varies widely. • Agreement varies to a degree that may render CXR alone ineffective for triage, especially for indeterminate cases. • Agreement for serial CXR change is moderate, limiting utility in guiding management

    Hydrogen Storage Materials for Mobile and Stationary Applications: Current State of the Art

    Get PDF
    One of the limitations to the widespread use of hydrogen as an energy carrier is its storage in a safe and compact form. Herein, recent developments in effective high-capacity hydrogen storage materials are reviewed, with a special emphasis on light compounds, including those based on organic porous structures, boron, nitrogen, and aluminum. These elements and their related compounds hold the promise of high, reversible, and practical hydrogen storage capacity for mobile applications, including vehicles and portable power equipment, but also for the large scale and distributed storage of energy for stationary applications. Current understanding of the fundamental principles that govern the interaction of hydrogen with these light compounds is summarized, as well as basic strategies to meet practical targets of hydrogen uptake and release. The limitation of these strategies and current understanding is also discussed and new directions proposed
