Buod Ng Tigre Tigre free essay sample
More formally, a function is defined as a set of finite lists of objects, one for each combination of possible arguments. In each list, the initial elements are the arguments, and the final element is the value. For example, theà à function contains the listà , indicating that integer successor ofà à isà . A relation is another kind of interrelationship among objects in the universe of discourse. More formally, aà relationà is an arbitrary set of finite lists of objects (of possibly varying lengths). Each list is a selection of objects that jointly satisfy the relation. For example, the lt; relation on numbers contains the listà , indicating thatà à is less thanà . Note that both functions and relations are defined as sets of lists. In fact, every function is a relation. However, not every relation is a function. In a function, there cannot be two lists that disagree on only the last element. This would be tantamount to the function having two values for one combination of arguments.

For example, the listà à is a member of theà à function, and there is no other list of length 2 withà à as its first argument, i. e. there is only one successor forà . By contrast, the lt; relation contains the listsà ,à , and so forth, indicating thatà is less thanà ,à , and so forth. Many mathematicians require that functions and relations have fixed arity, i. e they require that all of the lists comprising a function or relation have the same length. The definitions here allow for functions and relations with variable arity, i. e. t is perfectly acceptable for a function or a relation to contain lists of different lengths. For example, the + function contains the listsà à andà , reflecting the fact that the sum ofà à andà à isà à and the fact that the sum ofà à andà à andà à isà . Similarly, the relation lt; contains the listsà à andà , reflecting the fact thatà à is less thanà à and the fact thatà à is less thanà à andà à is less thanà . This flexibility is not essential, but it is extremely convenient and poses no significant theoretical problems. Relation:à à A relation is simply a set of ordered pairs. | A relation can be any set of ordered pairs.

Clark and Menefee Architects essays
Clark and Menefee Architects essays Maggie Cookman September 27, 2000 The Reid House was designed by W.G. Clark and Charles Menefee and built in Johns Island, SC in 1986. Menefee and Clark designed primarily in the American South. Clark and Menefee are known for their tripartite vertical organization. The base level normally consists of secondary bedroom(s)/studio spaces and services. The First floor is a piano nobile of principal rooms with a double-height living space. The attic level usually consists of the master bedroom and bath. The Reid House is set up in this fashion. The house is located in a modest setting, surrounded by house trailers and cheaply built houses. The image of the house was derived from vernacular farm buildings as well as from more formal Palladian structures. One author described the setting as Johns Island, a peaceful landscape where truck farmers tend tomato fields carved out of scrub-pine and dwarf-cedar forests, and where the front yards of shacks are littered with junked cars, rusting agricultural machinery, an d other decaying impedimenta of the Industrial Revolution. The house is a three-story tower with two components. The first is a 20 ft. sq. section made of concrete block, housing the living and bedrooms, referred to as the served space(s). The second part, referred to as the serving space(s), is a wood-frame shed that holds the kitchen and the bathrooms. These two components are joined at the fireplace and chimney, around which the stair winds. The materials used for the house are inexpensive, in keeping with the surrounding structures. One section is made of concrete blocks, exposed on the inside and covered with waterproofing paint on the outside. The other part of the house is sheathed in plywood and battens and its roof is covered in asphalt shingle. The floors are painted pi ...
