The following example is a realization of that perception. Traffic crash coordinate data from Washtenaw County Michigan for the years 1968-1970 has been assembled and subsequently displayed in a computer generated film animation. The symbol display algorithm is written so that as a crash increases in severity of injury, the larger the symbol and the longer it is displayed. Two crash sequences are displayed: the first in chronological order from 1968-1970 by 24 hour increments, and the second for a composite week by 15 minute increments. The result is a computer animated film about 7 minutes duration.","PeriodicalId":72321,"journal":{"name":"ASSETS.

Geisler","doi":"10.1145/800192.805743","DOIUrl":"https://doi.org/10.1145/800192.805743","url":null,"abstract":"A student initiated project has led to the use of a new technique and the development of a new device which can provide a means of communication for severely handicapped people, especially useful for those who are both mute and unable to use a typewriter. The device, called the Auto-Com (Auto-Monitoring Communication Board), was developed especially for use by individuals with afflictions which result in severe spastic motions.\u0000 For these individuals, most devices that utilize switches are extremely difficult or impossible to operate. This is due to the fact that normal switches, levers and keyboards all rely on a discrete motion of some form for their operation. Because of sporadic motions, these people are constantly making errors due to false triggering of the switches. These errors are very frustrating for them and usually result in rapid rejection of the device.\u0000 Some devices have been developed which overcome the spastic motion problem by using large, gross motor movements as the signal source. In this manner switches can be successfully used, but their number is limited. Special techniques are then required to specify all of the alphanumeric characters with these few switches.\u0000 In contrast, the Auto-Com copes with the problem of spastic motion by using the lack of motion rather than its presence as its control signal. Thus, any sudden Jerks, movements or lack of control will be ignored, allowing error-free control. This technique also allows the close packing of signal switches: more than 80 of them are located in a 12\" × 15\" area. This large number of switches allows a simple one-to-one relationship between the switches and the characters, making understanding and operation of the unit simple, even for a young child. This direct specification of each letter also reduces the time needed by the user to select a letter.\u0000 The current model of the Auto-Com consists of a sensing board, a hand-piece and several output devices. The sensing board is similar in appearance to a “language board”, a commonly used communication technique for the handicapped. A typical language board is a flat piece of wood with letters, numbers and some common words painted on it. The handicapped person communicates by pointing out the letters of his message to another person. The Auto-Com works in much the same manner except that it is auto-monitoring. It does not require the presence of another person. Like the language board, the surface of the sensing board is hard and smooth and has letters painted on it. Communication is accomplished by sliding the handpiece over the board's surface until its black post (a magnet) is located over a desired letter. A magnetic reed switch located directly underneath that letter is then closed. If the magnet is kept there for a short (adjustable) period of time, the letter is printed on the TV screen or teletype unit. Since the magnet does not need to stand absolutely still, but only remain within an area surrounding the letter, the","PeriodicalId":72321,"journal":{"name":"ASSETS.

By inconsistency I understand that not all relevant parts of the tree are considered or that parts are considered or pruned for incorrect reasons. Typical inconsistencies are fixed depth limitations, incorrect quiescence analysis and the ordinary methods of forward pruning. Consistency is a sufficient, but fortunately not always necessary condition for correct results.","PeriodicalId":72321,"journal":{"name":"ASSETS.

The algorithm is strongly influenced by the method used for factoring multivariate polynomials over the integers. It uses an extension of the Hensel lemma approach originally suggested by Zassenhaus for factoring univariate polynomials over the integers. We point out that the cost of the Modular GCD algorithm applied to sparse multivariate polynomials grows at least exponentially in the number of variables appearing in the GCD. This growth is largely independent of the number of terms in the GCD. The new algorithm, called the EZ (Extended Zassenhaus) GCD Algorithm, appears to have a computing bound which in most cases is a polynomial function of the number of terms in the original polynomials and the sum of the degrees of the variables in them. Especially difficult cases for the EZ GCD Algorithm are described. Applications of the algorithm to the computation of contents and square-free decompositions of polynomials are indicated.","PeriodicalId":72321,"journal":{"name":"ASSETS.

Some of this knowledge is given to COKO in the form of a 12,000 line FORTRAN program. Using this knowledge COKO plays very poorly but at the super rate of approximately one move/sec. The use of a brute force selective tree searching procedure yields an order of magnitude improvement in performance at the standard rate of 3 min./move. Perhaps three orders of magnitude additional improvement is needed to defeat the world champion, a gap which must be bridged, if ever, by programming more chess knowledge into the machine. In addition “inter-snap judgment communication” is described as a natural, powerful procedure frequently used by humans to guide their selective search and as a point of emphasis for future development.","PeriodicalId":72321,"journal":{"name":"ASSETS.

In some cases (the function heading) decisions are inverted from the language and in others (statement numbers) inputs are automatically positioned. In general, only syntax within the statements is checked, but some global checking (multiple main programs) is performed. Alternate forms of statements are often displayed with the unwanted ones being eliminated as entries are made.
