The throughput-delay results of the two retransmission methods were compared by extensive simulations and found to be essentially the same. [8] Lam’s model provides mathematically rigorous answers to the stability questions of slotted ALOHA, as well as an efficient algorithm for computing the throughput-delay performance for any stable system.
In the Dojo Toolkit's Deferred API as of version 1.5, a consumer-only promise object represents a read-only view. [7] In Alice ML, futures provide a read-only view, whereas a promise contains both a future and the ability to resolve the future [8] [9] In .NET System.Threading.Tasks.Task<T> represents a read-only view.
In many contexts, including C++, C# and Java, an object is created via special syntax like new typename(). In C++, that provides manual memory management, an object is destroyed via the delete keyword. In C# and Java, with no explicit destruction syntax, the garbage collector destroys unused objects automatically and non-deterministically.
The group delay and phase delay properties of a linear time-invariant (LTI) system are functions of frequency, giving the time from when a frequency component of a time varying physical quantity—for example a voltage signal—appears at the LTI system input, to the time when a copy of that same frequency component—perhaps of a different physical phenomenon—appears at the LTI system output.
Within digital electronics, the DIMS (delay-insensitive minterm synthesis) system [1] is an asynchronous design methodology making the least possible timing assumptions. Assuming only the quasi-delay-insensitive delay model the generated designs need little if any timing hazard testing. The basis for DIMS is the use of two wires to represent ...
A quasi-delay-insensitive circuit (QDI circuit) is an asynchronous circuit design methodology employed in digital logic design.Developed in response to the performance challenges of building sub-micron, multi-core architectures with conventional synchronous designs, QDI circuits exhibit lower power consumption, extremely fine-grain pipelining, high circuit robustness against process–voltage ...
Although the software industry largely standardized on call-by-value and call-by-reference evaluation, [5] active study of call-by-name continued in the functional programming community. This research produced a series of lazy evaluation programming languages in which some variant of call-by-name is the standard evaluation strategy.
Packet delivery time = Transmission time + Propagation delay In case of a network connection mediated by several physical links and forwarding nodes, the network delivery time depends on the sum of the delivery times of each link, and also on the packet queuing time (which is varying and depends on the traffic load from other connections) and ...
