The software thread running on processor #1 loops while the value of f is zero, then it prints the value of x. The software thread running on processor #2 stores the value 42 into x and then stores the value 1 into f. Pseudo-code for the two program fragments is shown below. The steps of the program correspond to individual processor instructions.
Flutter is an open-source UI software development kit created by Google. It can be used to develop cross platform applications from a single codebase for the web , [ 3 ] Fuchsia , Android , iOS , Linux , macOS , and Windows . [ 4 ]
A geofence can be dynamically generated (as in a radius around a point location) or match a predefined set of boundaries (such as school zones or neighborhood boundaries). The use of a geofence is called geofencing , and one example of use involves a location-aware device of a location-based service (LBS) user entering or exiting a geofence.
A node fence (or I/O fence) is a virtual "fence" that separates nodes which must not have access to a shared resource from that resource. It may separate an active node from its backup. If the backup crosses the fence and, for example, tries to control the same disk array as the primary, a data hazard may occur.
A variant called boundary fill uses the same algorithms but is defined as the area connected to a given node that does not have a particular attribute. [ 1 ] Note that flood filling is not suitable for drawing filled polygons, as it will miss some pixels in more acute corners. [ 2 ]
In a virtual electric fence system, each animal has a collar with a GPS unit which is set to produce first an audible warning and then a shock as the animal approaches a programmable boundary. Pet fences to control domestic dogs have been used since 1973, and the first system for livestock control was developed by Peck's Invisible Fence Co, now ...
A fence is a structure that encloses an area, typically outdoors, and is usually constructed from posts that are connected by boards, wire, rails or netting. [1] A fence differs from a wall in not having a solid foundation along its whole length. [2] Alternatives to fencing include a ditch (sometimes filled with water, forming a moat).
The method consists of filling the flow area with stream and equipotential lines, which are everywhere perpendicular to each other, making a curvilinear grid.Typically there are two surfaces (boundaries) which are at constant values of potential or hydraulic head (upstream and downstream ends), and the other surfaces are no-flow boundaries (i.e., impermeable; for example the bottom of the dam ...
