Optimistic concurrency control ( OCC ), also known as optimistic locking, is a non-locking concurrency control method applied to transactional systems such as relational database management systems and software transactional memory. OCC assumes that multiple transactions can frequently complete without interfering with each other.
Unofficial but common URI schemes. URL scheme in the GNOME desktop environment to access file (s) with administrative permissions with GUI applications in a safer way, instead of the insecure-considered sudo, gksu & gksudo . URL scheme can be used by packaged applications to obtain resources that are inside a container.
Kuber is a smokeless tobacco product, known for its highly addictive properties and its unique presentation disguised as a mouth freshener. It originated in India and has gained attention for its widespread use and impact on public health in various countries, including Uganda .
Electronic authentication. Electronic authentication is the process of establishing confidence in user identities electronically presented to an information system. [1] Digital authentication, or e-authentication, may be used synonymously when referring to the authentication process that confirms or certifies a person's identity and works.
Euler–Maruyama method. In Itô calculus, the Euler–Maruyama method (also called the Euler method) is a method for the approximate numerical solution of a stochastic differential equation (SDE). It is an extension of the Euler method for ordinary differential equations to stochastic differential equations. It is named after Leonhard Euler ...
The Sakai–Kasahara scheme, also known as the Sakai–Kasahara key encryption algorithm ( SAKKE ), is an identity-based encryption (IBE) system proposed by Ryuichi Sakai and Masao Kasahara in 2003. [1] Alongside the Boneh–Franklin scheme, this is one of a small number of commercially implemented identity-based encryption schemes.
For a scheme X over a field k and any field extension E of k, the base change X E means the fiber product X × Spec(k) Spec(E). Here X E is a scheme over E. For example, if X is the curve in the projective plane P 2 R over the real numbers R defined by the equation xy 2 = 7z 3, then X C is the complex curve in P 2 C defined by the same equation.
High-resolution schemes are used in the numerical solution of partial differential equations where high accuracy is required in the presence of shocks or discontinuities. They have the following properties: Second- or higher- order spatial accuracy is obtained in smooth parts of the solution. Solutions are free from spurious oscillations or ...
