Multimedia Storage
Published in Sreeparna Banerjee, Elements of Multimedia, 2019
Cloud storage is a model of computer data storage where digital data is stored in logical pools. The physical storage is embodied in multiple servers and even multiple locations. The physical storage is generally owned and managed by hosting companies. Methods of access are: Co-located cloud computing servicesWeb service application programming interfaces (APIs) like cloud desktop storages, cloud storage gateways, or Web-based content management systems.
Stress analysis and thermoelastic instability of an annular functionally graded rotating disk
Published in Journal of Thermal Stresses, 2022
Hassan Bahaloo, Hamid Nayeb-Hashemi
With the commercial production of Functionally Graded Materials (FGM) in 1980s [1], they became a design option for rotating disks to obtain a more uniform in-plane stress to increase the performance. Perhaps Horgan and Chen were the first to study the mechanical response of FG rotating disks under plane stress and plane strain conditions [2]. They found that with the proper material distribution and modulus gradient, uniform radial and hoop stress distributions can be achieved. It was demonstrated that application of FG materials results in a reduced stress concentration and that can prevent premature failure in structures and systems during their service; e.g. rotating disks used for computer data storage, circular saws, and turbo-machinery [3]. Mechanical behavior of FG circular/annular plates [4–9] and FG rotating disks has been studied extensively [10–17].
Determination of phorbol ester content in Balanites aegyptiaca and use of enzymatic-catalyzed biodiesel in diesel engine
Published in Biofuels, 2019
The engine was tested within measured load conditions at engine speeds from 1500 to 1580 rpm. At first with the biodiesel n-butanol blends, the engine was allowed to run with D100 initially at a steady speed for the smooth running of the engine. After achieving steadiness, readings and graphs were stored in the computer data storage system. Tests were carried out for all test fuels and the data were stored in the system. Test fuel samples were allowed to run until the fuel in the fuel system was completely drained. Then the same procedure was repeated for the next test fuel mixture.
