The renewal interval determined by the random point t (shown in red) is stochastically larger than the first renewal interval. See also: List of paradoxes § Mathematics A curious feature of renewal processes is that if we wait some predetermined time t and then observe how large the renewal interval containing t is, we should expect it to be ...
After an initial key exchange it manages the ongoing renewal and maintenance of short-lived session keys. It combines a cryptographic so-called "ratchet" based on the Diffie–Hellman key exchange (DH) and a ratchet based on a key derivation function (KDF), such as a hash function, and is therefore called a double ratchet.
F(t) is the cumulative distribution function (CDF) of the underlying failure time distribution, q is the restoration factor, is the vector of parameters of the underlying failure-time distribution. A closed-form solution to the G-renewal equation is not possible. Also, numerical approximations are difficult to obtain due to the recurrent ...
These group keys allowed all the agents in a particular group to receive a single coded message. [ 2 ] [ 3 ] In present-day applications, group keys are commonly used in conditional access systems, where the key is the common key used to decrypt the broadcast signal, and the group in question is the group of all paying subscribers.

Interval scheduling is a class of problems in computer science, particularly in the area of algorithm design. The problems consider a set of tasks. Each task is represented by an interval describing the time in which it needs to be processed by some machine (or, equivalently, scheduled on some resource).
Contemporary time sheet. A timesheet (or time sheet) is a method for recording the amount of a worker's time spent on each job. Traditionally a sheet of paper with the data arranged in tabular format, a timesheet is now often a digital document or spreadsheet. The time cards stamped by time clocks can serve as a timesheet or provide the data to ...
