Targets for DSA are therefore usually set quite high and the calculation and review of the metric important. Some organizations experience problems in producing delivery schedule adherence information this can be caused by a failure of systems to record delivery forecast information, unreliable processes and poor communication between buyer and ...
Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Images are produced using contrast medium by subtracting a "pre-contrast image" or mask from subsequent images, once the contrast medium has been introduced into a ...
The Digital Signature Algorithm (DSA) is a public-key cryptosystem and Federal Information Processing Standard for digital signatures, based on the mathematical concept of modular exponentiation and the discrete logarithm problem. In a public-key cryptosystem, a pair of private and public keys are created: data encrypted with either key can ...
On March 29, 2011, two researchers published an IACR paper [9] demonstrating that it is possible to retrieve a TLS private key of a server using OpenSSL that authenticates with Elliptic Curves DSA over a binary field via a timing attack. [10] The vulnerability was fixed in OpenSSL 1.0.0e. [11]
A sparse matrix obtained when solving a finite element problem in two dimensions. The non-zero elements are shown in black. In numerical analysis and scientific computing, a sparse matrix or sparse array is a matrix in which most of the elements are zero. [1]
A data structure known as a hash table.. In computer science, a data structure is a data organization and storage format that is usually chosen for efficient access to data. [1] [2] [3] More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data, [4] i.e., it is an algebraic structure about data.
YDS (renamed YDSA in 2017 to identify with the more prominent DSA name) expanded following youth support for Bernie Sanders' 2016 presidential candidacy. According to a YDSA organizer, the group expanded from 25 to 84 registered chapters between 2016 and 2019. [31] As of June 2023, DSA listed 125 official youth chapters. [32]
A Directory System Agent (DSA) is the element of an X.500 directory service that provides User Agents with access to a portion of the directory (usually the portion associated with a single Organizational Unit).
