Publication Year: 1975, Page(s):297 - 311
Cited by:  Papers (13)
| | PDF (6730 KB)

A probabilistic automaton based on competing evolutionary search processes is considered as an on-line real-time adaptive controller for complex plants with multimodal performance index structures that are modified under measurable but uncontrollable random environmental variations. The scheme described includes mechanisms of storage and retrieval to take advantage of control experience gained pri... View full abstract»

• ### Some Applications of Optimization Techniques to Water Quality Modeling and Control

| | PDF (1877 KB)

Dynamic water quality modeling methodology is presented along with a number of applications of optimization theory to deterministic water quality modeling and control. Two of the applications are basically parameter estimation problems. The first involves the generation of a dynamic model for the behavior of coliform bacteria in Grand Traverse Bay, while the second is concerned with the estimation... View full abstract»

• ### On Assessing Model Adequacy

Publication Year: 1975, Page(s):322 - 330
Cited by:  Papers (10)
| | PDF (1855 KB)

A procedure is proposed which allows one to assess the adequacy of models to represent objects. Only the class of inverse problems has been considered in detail. The procedure is based on the definition of a vectorial distance between models. It allows one to order models from the standpoint of their adequacy and apply to the problem many results of ordered sets. When the set of models admits a mi... View full abstract»

• ### Error Analysis of Nonlinear Simulations: Applications to World Dynamics

Publication Year: 1975, Page(s):331 - 340
Cited by:  Papers (5)
| | PDF (1695 KB)

Two algorithms for error analysis of nonlinear continuous simulations are derived and presented. A first-order algorithm is developed initially, and its relationship to standard sensitivity algorithms is indicated. This is followed by the development of a Monte Carlo simulation algorithm. The limitations and computational efficiencies of each are discussed and compared. Both algorithms are develop... View full abstract»

An algorithm for finding a continuous-time linear analog to a discrete-time linear system is derived. It is employed in the selection of optimal economic policy, and an example using Samuelson's multiplier-accelerator model is described. View full abstract»

• ### Introduction and Survey of Group Decision Making with Applications to Worth Assessment

Publication Year: 1975, Page(s):346 - 358
Cited by:  Papers (16)
| | PDF (2983 KB)

In a society, decisions often affect groups of people instead of isolated individuals. In such cases, planners and decision makers are usually expected to consider the preferences of Previous approaches to the problem of amalgamating the individual preferences into a form which can be used to guide the decision maker are surveyed, and the role worth assessment plays in the group decision making pr...

Publication Year: 1975, Page(s):375 - 380
Cited by:  Papers (1)
| | PDF (1556 KB)

A conceptual framework for applying artificial intelligence (AI) techniques in computer-assisted instruction (CAI) is described. The student progresses through four phases (faces'') of interaction with the computer acting as benevolent mentor,'' cognizant tool,'' problem-solving partner,'' and learner.'' The first phase serves to introduce the problem space, with the computer initiating ... View full abstract»

| | PDF (1842 KB)

Parallel web automata (PWAÂ¿a generalization of cellular arrays to arbitrary graph structuresÂ¿are defined. It is shown that such automata make poor acceptors (i.e., they are not good recognizers of their own graph structures). However, they can be used to perform parallel local pattern matching (with respect to patterns of bounded size) on themselves, so that they have potential usefulness as mod... View full abstract»

• ### Region Extraction by Averaging and Thresholding

Publication Year: 1975, Page(s):383 - 388
Cited by:  Papers (39)
| | PDF (4719 KB)

Regions in a picture that differ texturally from their surroundings can often be extracted by 1) applying a local operation to every point of the picture, 2) averaging the results, and 3) thresholding. This approach will usually not work if there are too many differently textured regions present, since the average for one type of region may then be indistinguishable from the average resulting from...

| | PDF (1003 KB)

Although motion is one of the most fundamental aspects of the visual world, its use has not been widely explored in the field of scene description. This correspondence describes a program that demonstrates the feasibility of segmenting a scene into regions on the basis of velocity. A velocity measure is obtained by determining the amount of displacement of a reference feature between two pictures ... View full abstract»

Optimal preventive maintenance policies, for a machine subject to deterioration with age and intermittent breakdowns and repairs, are derived using optimal control theory. The optimal policies are shown to be of bang-bang nature. The extension to the case when there are a large number of identical machines and several repairmen in the system is considered next. This model takes into account the wa... View full abstract»

• ### Mutual Entropy Interactions Between Growth Patterns of Oregon Counties

Publication Year: 1975, Page(s):399 - 402

Shannon's mutual information is proposed as a measure of lagged statistical dependence between the temporal patterns of economic/demographic growth for subregions, where the year-to-year ratio of births is taken as the growth index for each subregion. Application of the measure to 31 of the 36 counties in Oregon, using vital statistics for the years 1919-1968, yields results that seem, for the mos... View full abstract»
