DICONDE
Digital Imaging and Communication for Nondestructive Evaluation (DICONDE) is a vendor-neutral digital data storage and transmission protocol that defines the organization of nondestructive testing (NDT) inspection data and associated metadata in a standard format. DICONDE is based on and inherits from the universally adopted medical standard, DICOM, which facilitates the interoperability of imaging, video, and signal data acquisition equipment through data storage, query, and network communication protocols. The ASTM International standards organization maintains and holds the copyright to the relevant DICONDE published standards, including a tutorial guide designated as E3169. Development and maintenance of the standard is handled by committee E07 on nondestructive testing. Subcommittee E07.11 on DICONDE is concerned with the formulation of standards for the communication and storage of data generated by all nondestructive testing methodologies capable of handling data in an electronic format. ASTM maintains a page dedicated to DICONDE and openly provides resources on the ASTM DICONDE home page.

Windows Defender
Microsoft Defender (known as Windows Defender before Windows 10 November 2019 Update or Windows Defender Antivirus in Windows 10 Creators Update and later) is an anti-malware component of Microsoft Windows. It was first released as a downloadable free anti-spyware program for Windows XP, and was later shipped with Windows Vista and Windows 7. It has evolved into a full antivirus program, replacing Microsoft Security Essentials as part of Windows 8 and later versions.

Aquaculture System Using Cloud-Based Autonomous Drones
Aquaculture System Using Cloud-Based Autonomous Drones incorporated artificial intelligence (AI) services using computer vision and combined various deep learning recognition models to achieve scalability and added functionality, in order to perform aquaculture surveillance tasks. The recognition model is embedded in the aquaculture cloud, to analyze images and videos captured by the autonomous drone. The recognition models detect people, cages, and ship vessels at the aquaculture site. The inclusion of AI functions for face recognition, fish counting, fish length estimation and fish feeding intensity provides intelligent decision making. For the fish feeding intensity assessment, the large amount of data in the aquaculture cloud can be an input for analysis using the AI feeding system to optimize farmer production and income. The autonomous drone and aquaculture cloud services are cost-effective and an alternative to expensive surveillance systems and multiple fixed-camera installations. The aquaculture cloud enables the drone to execute its surveillance task more efficiently with an increased navigation time. The mobile drone navigation app is capable of sending surveillance alerts and reports to users. Our multifeatured surveillance system, with the integration of deep-learning models, yielded high-accuracy results.

Optical Fiber Sensors and Sensing Networks
Optical fiber sensors present several advantages in relation to other types of sensors. These advantages are essentially related to the optical fiber properties, i.e., small, lightweight, resistant to high temperatures and pressure, electromagnetically passive, among others. Sensing is achieved by exploring the properties of light to obtain measurements of parameters, such as temperature, strain, or angular velocity. In addition, optical fiber sensors can be used to form an Optical Fiber Sensing Network (OFSN) allowing manufacturers to create versatile monitoring solutions with several applications, e.g., periodic monitoring along extensive distances (kilometers), in extreme or hazardous environments, inside structures and engines, in clothes, and for health monitoring and assistance.

Ring
Ring LLC is a home security and smart home company owned by Amazon. Ring manufactures home security products that incorporate outdoor surveillance cameras, including the Ring Video Doorbell smart doorbell, and hosts an app, Neighbors, for online social sharing of captured footage among users. Ring also provides video footage from its cameras and data from its Neighbors app to law enforcement agencies on request. Its police partnerships have been criticized by civil rights advocacy groups as building an invasive private surveillance network.

High-frequency analysis, Model Validation and Intraday risk metrics
Despite the growing amount of research in the field of high frequency financial data analysis, few studies have focused on model validation and high-frequency risk measures. This study contributes to the literature in the following ways: A rigorous model validation, both in terms of in-sample fit and out-sample performance for the MC-GARCH model under five error distributions is provided. Statistical and graphical tests are conducted to validate the models. One component of the MC-GARCH model is the daily variance forecast. For this purpose, the GARCH(1,1) and EGARCH(1,1) under the five error distributions are compared and the best model among the 10 GARCH models is used to forecast the daily variance. The modelling and forecasting performance of the MC-GARCH model under different distributional assumptions is assessed in this study. The 99% intraday VaR is forecasted and three backtesting procedures are used. This is the first study to assess the VaR predictive ability of the MC-GARCH models by using an asymmetric VaR loss function. This is the first study to forecast the intraday expected shortfall under different distributional assumptions for the MC-GARCH model. Again, three backtests are used including the recently proposed ES regression backtest. Due to the high importance of risk management, the results of this study may contribute in many fields. This study is highly relevant to the banking industry since banks are required to calculate risk metrics on a daily basis for internal control purposes and for determining their capital requirements. Risk measurement is also essential to the insurance industry from the pricing of insurance contracts to determining the Solvency Capital Requirement (SCR) and therefore the results of this study might be useful. Any other organisation having an exposure to some kind of financial risk might benefit from this study.

Nvidia Quadro
Quadro is Nvidia's brand for graphics cards intended for use in workstations running professional computer-aided design (CAD), computer-generated imagery (CGI), digital content creation (DCC) applications, scientific calculations and machine learning. The GPU chips on Quadro-branded graphics cards are identical to those used on GeForce-branded graphics cards. Differences between the Quadro and GeForce cards include the use of ECC memory and enhanced floating point precision. These are desirable properties when the cards are used for calculations which, in contrast to graphics rendering, require reliability and precision. The Nvidia Quadro product line directly competes with AMD's Radeon Pro line of professional workstation cards.

Snap
Snap is a software packaging and deployment system developed by Canonical for operating systems that use the Linux kernel and the systemd init system. The packages, called snaps, and the tool for using them, snapd, work across a range of Linux distributions and allow upstream software developers to distribute their applications directly to users. Snaps are self-contained applications running in a sandbox with mediated access to the host system. Snap was originally released for cloud applications but was later ported to also work for Internet of Things devices and desktop applications.
