  Initial object - Wikipedia, the free encyclopedia
In mathematics, an initial object of a category C is an object I in C such that to every object X in C, there exists precisely one morphism I → X.
The empty set is the unique initial object in the category of sets; every one-element set (singleton) is a terminal object in this category; there are no zero objects.
The kernel of f is a terminal object in this category; this is nothing but a reformulation of the universal property of kernels.

Directly from the definition, one can show however that if an initial object exists, then it is unique (Click link for more info and facts about up to) up to a unique ((biology) similarity or identity of form or shape or structure) isomorphism.
Similarly, the empty space is the unique initial object in the category of ((mathematics) any set of points that satisfy a set of postulates of some kind) topological spaces; every one-point space is a terminal object in this category.
The singletons are not initial: while every non-empty set admits a (A mathematical relation such that each element of one set is associated with at least one element of another set) function from a singleton, this function is in general not unique.

In project management, a terminal element is the lowest element (activity or deliverable) in a work breakdown structure; it is not further subdivided.
Terminal elements are the items that are estimated in terms of resource requirements, budget and duration, linked by dependencies and scheduled.
A terminal object of a category has the property that every object in the category (including itself) has exactly one arrow leading to it.

 Terminal Object [TAPI 3.1]   (Site not responding. Last check: 2007-10-21)
In TAPI version 3.0 and later, the TAPI object model uses terminal objects to represent the source or sink of a media stream associated with a call or communications session.
The Terminal object represents a source or renderer, such as a microphone or a speaker.
Terminals are normally implemented by a media service provider (MSP) and terminal objects will not be available if there is no MSP associated with a communications session.

 Speed of a Skydiver (Terminal Velocity)
For a heavy object, the terminal velocity is generally greater than a light object.
The terminal velocity for a skydiver was found to be in a range from 53 m/s to 76 m/s.
Terminal velocity is often reported to be approximately 60 m/s for a typical skydiver in free fall.

 Terminal
The Terminal class is often used to enhance applications where a commandline that accesses the underlying operating system may be useful.
When creating a new terminal object, it should be contained by a drawable area, such as a Render object.
However, you may want the terminal object to receive its keyboard input from a different source, which can be achieved by writing a new object ID to this field.

 Questions?
he Terminal Velocity of an object falling through the air is the velocity at which the force of drag due to air friction on the object is equal to the acceleration of gravity.
Heavier objects of the same size and shape (denser objects) have a higher terminal velocity since the weight of the object, and thus the force of acceleration on the object, is many times greater than the force of drag due to air friction.
Since gravity is directly proportional to the downward force accelerating a falling object, the higher the gravity, the higher the force, and thus the higher the terminal velocity.

The object constructed by the action tags for a child non-terminal may then be used in the enclosing parent non-terminal to construct its value object by referring to the child non-terminal in one of two ways:
While the value of each non-terminal is an object, it is also useful in some cases for a non-terminal to be treated as a simple value such as a number or string.
The default value for this.$value (and therefore for the non-terminal value object when used in a context where a simple value is needed) is a string which is the concatenation of the string values of all the items in the non-terminal, separated by spaces.

 Category theory
Then it becomes possible to relate different categories by functors, generalizations of functions which associate to every object of one category an object of another category and to every morphism in the first category a morphism in the second.
Any monoid forms a small category with a single object x, and where every element of the monoid is a morphism from x to x (the monoid operation yields the categorical composition of morphisms).
Any directed graph can be considered as a small category: the objects are the vertices of the graph and the morphisms are the paths in the graph.

 Terminal Velocity
An object which is falling through the atmosphere is subjected to two external forces.
When drag is equal to weight, there is no net external force on the object and the object falls at a constant velocity as described by Newton's first law of motion.
The terminal velocity equation tells us that an object with a large cross-sectional area or a high drag coefficient falls slower than an object with a small area or low drag coefficient.

 Initial and Terminal Objects   (Site not responding. Last check: 2007-10-21)
An object q is universal, or initial, if for every object r in the category, there is one and only one morphism from q to r.
An object q is couniversal, or terminal, if for every object r in the category, there is one and only one morphism from r to q.
For instance, in the category of sets, the empty set is initial, a set with 1 element is terminal, and since these objects have different cardinalities, there is no zero object.

 Specification
The Absorb() method is called when a Visitor arrives at the A-side of the Terminal.
Typically a Terminal object simply queries the Visitor for relevant information and then induces the Visitor to Suicide().
InjectionNotification() gives the derived Terminal object an opportunity to observe the types of Visitors that are being Injected out of it by other Actors.

Connection objects may be in one of several states, indicating the current state of the relationship between the Call and the Address.
The Terminal is also known as the "physical" endpoint of a call, because it corresponds to a physical piece of hardware.
TerminalConnection objects model the relationship between a Connection and the physical endpoint of a Call, which is represented by the Terminal object.

 ODIF Specification
An object reference is composed of the name of the object class and the instance's unique identifier.
If only object references could be used, a reader would have to constantly search through the file to locate each of the object instances used in an object's attributes in order to see all of its values.
If the same object instance is used in more than one location, use of object references can't be avoided, but if the instance is used as a value of only one attribute, readability can be improved by placing the object's specification within the attribute's value.

Terminal Services security is controlled primarily through properties on Terminal Services connection objects using the Microsoft Management Console (MMC) Terminal Services Configuration snap-in.
Like all objects in Win2K, connection objects have an ACL that controls who can open a session to the server through Terminal Services and who can perform administrative functions on those sessions and the connection itself.
Terminal Services gives you the ability to temporarily disconnect from your session, walk over to another computer, and reconnect to the session from that workstation.

 Suspicious object prompts terminal evacuation - at worldbookers.com
GRAPEVINE, Texas (AP) -- Part of an American Airlines terminal at the Dallas-Fort Worth International Airport was evacuated for several hours Thursday after baggage screening detected a suspicious object that turned out to be a vintage microphone, authorities said.
The terminal was reopened and airport operations resumed after a bomb squad used a robot to remove the pipe-shaped object that had wires running through it.
Ann Davis, a Boston-based spokeswoman for the Transportation Security Administration, said officials determined late Thursday afternoon that the microphone was harmless.
