• ### Acceptable decision processes and acceptable risks in public sector regulations

Publication Year: 1983, Page(s):113 - 124
Cited by:  Papers (1)
| | PDF (3077 KB)

Risk analysis and risk-benefit analysis are more and more widely used for regulatory purpose. Instead of searching for an acceptable risk, it is proposed here to study some characteristics of acceptable decision processes in which risk analysis results constitute part of the information but can in no way be used as decision criteria. It is argued that consistency of standards relies on consistency... View full abstract»

• ### On the value of assessing preferences explicitly for bargaining

Publication Year: 1983, Page(s):125 - 136
| | PDF (2127 KB)

A game under uncertainty is used to investigate two value-of-information questions that arise in competitive situations: 1) Is it worthwhile for a bargainer to go through the effort of quantifying his own preferences over outcomes before bargaining? and 2) Should a bargainer prefer that his opponent quantify his preferences as well? The situation is modeled by a two-by-two, two-person game with co... View full abstract»

• ### Decision and information structures in regret models of judgment and choice

Publication Year: 1983, Page(s):136 - 145
| | PDF (2062 KB)

The use of the preference relation selection of A and rejection of B is preferable to selection of B and rejection of A' is discussed. This contextual relation yields descriptive models of choice under uncertainty that explain many observed violations of classical single attribute utility theory. It is shown that successful use of this relation, for descriptive purpose... View full abstract»

• ### A dynamic decision model of human task selection performance

Publication Year: 1983, Page(s):145 - 166
Cited by:  Papers (21)
| | PDF (4039 KB)

Human information processing and task selection procedures in a dynamic multitask supervisory control environment are discussed. The results of a joint experimental and analytic program were assimilated into a normative dynamic-decision model for predicting human task-selection performance. To this end a general multitask experimental paradigm has been developed, wherein tasks of different value, ... View full abstract»

• ### An adaptive control model for human head and eye movements while walking

Publication Year: 1983, Page(s):167 - 174
Cited by:  Papers (5)
| | PDF (1525 KB)

When a person walks the head undergoes horizontal and vertical rotations, and also horizontal and vertical translations. To visually fixate on an object while walking, compensatory horizontal and vertical eye movements must be made. The model for this gaze (head plus eye) control system includes three types of eye movements: smooth pursuit, saccadic, and vestibulo-ocular. The smooth pursuit system... View full abstract»

• ### Statistical techniques in modeling of complex systems: Single and multiresponse models

Publication Year: 1983, Page(s):175 - 189
Cited by:  Papers (2)
| | PDF (2974 KB)

An exposition of statistical techniques in modeling complex systems (single and multiresponse models) that are representative of recent work on modeling systems is provided. The paper begins with several basic concepts related to linear and nonlinear models. The authors then examine four representative techniques of model discrimination which deal with use of nonintrinsic and intrinsic parameters,... View full abstract»

• ### Solving the find-path problem by good representation of free space

Publication Year: 1983, Page(s):190 - 197
Cited by:  Papers (240)
| | PDF (1549 KB)

Free space is represented as a union of (possibly overlapping) generalized cones. An algorithm is presented which efficiently finds good collision-free paths for convex polygonal bodies through space littered with obstacle polygons. The paths are good in the sense that the distance of closest approach to an obstacle over the path is usually far from minimal over the class of topologically equivale... View full abstract»

• ### A graph-theoretic algorithm for hierarchical decomposition of dynamic systems with applications to estimation and control

Publication Year: 1983, Page(s):197 - 207
Cited by:  Papers (7)
| | PDF (2036 KB)

A graph-theoretic scheme is proposed for the partitioning of dynamic systems into hierarchically ordered subsystems having independent inputs and outputs. The resulting subsystems are input-output reachable as well as structurally controllable and observable, so that a piece-by-piece' design of estimators and controllers can be accomplished for systems with large dimensions without excessive comp...

• ### Dynamic programming algorithm for optimal estimation of speech parameter contours

Publication Year: 1983, Page(s):208 - 214
Cited by:  Papers (13)  |  Patents (7)
| | PDF (1418 KB)

A method for incorporating the requirement of smoothness into the estimation procedure for speech parameters is described. The traditional method of estimating a speech parameter, such as the fundamental period or a formant, is to determine the speech parameter separately for each time frame, usually by optimizing a suitable function of the speech signal. However, it is known a priori that adjacen... View full abstract»

• ### On decomposition theory: Duality

Publication Year: 1983, Page(s):215 - 221
| | PDF (1356 KB)

Decomposition theory is concerned with the structures that arise in the decomposition of systems. It states from the premise that any method of system decomposition is based, either explicitly or implicitly, on some concept of dependence. The formal setting of decomposition theory is the dependence, an ordered-triple (E, M, D), where E is a nonempty set, M is a c... View full abstract»

• ### Evaluating a Delphi forecast on personal computers

Publication Year: 1983, Page(s):222 - 224
| | PDF (604 KB)

In 1978, a Delphi forecast was undertaken on future developments in personal computers (Nilles et al., 1980). The forecasts are compared with the actual outcomes and indicators available in 1982. The comparison shows the consensus reached by the Delphi panel to be almost completely accurate. View full abstract»

• ### On the learning behaviors of variable-structure stochastic automaton in the general n-teacher environment

Publication Year: 1983, Page(s):224 - 231
Cited by:  Papers (2)
| | PDF (1402 KB)

Learning behaviors of a stochastic automaton operating in a multiteacher environment are considered. As a generalized form of the LR-I scheme, the GLR-I scheme is proposed as a reinforcement scheme in a multiteacher environment. It is shown that the GLR-I scheme is absolutely expedient and ϵ-optimal in the general n-teacher enviro... View full abstract»

• ### Histogram concavity analysis as an aid in threshold selection

Publication Year: 1983, Page(s):231 - 235
Cited by:  Papers (45)
| | PDF (1781 KB)

A well-known heuristic for segmenting an image into gray level subpopulations is to select thresholds at the bottoms of valleys on the image's histogram. When the subpopulations overlap, valleys may not exist, but it is often still possible to define good thresholds at the `shoulders' of histogram peaks. Both valleys and shoulders correspond to concavities on the histogram, and this suggests that ... View full abstract»

• ### Comments on “hierarchical optimization of nonlinear dynamical systems with nonquadratic objective functions”

Publication Year: 1983, Page(s):235 - 236
| | PDF (536 KB)

Fawzy (1981) proposes a four-level hierarchical computation structure for the solution of nonlinear optimization problems of the Mayer form. It is shown that the fourth level of a four-level hierarchical optimization algorithm proposed by Fawzy is superfluous. View full abstract»

• ### Fairness and mutual profitability in collective behavior of automata

Publication Year: 1983, Page(s):236 - 241
| | PDF (1295 KB)

A certain class of noncooperative games is considered with two pure strategies for each of the automata players. The nature of the game is such that the pay-off of each player increases if any other participant in the game chooses the same pure strategy as that player, and decreases otherwise. The pay-off from a joint strategy is generally different for each automaton so that a joint strategy whic... View full abstract»

Consider a two-dimensional random variable (X, θ) with θ ∊ {θ1 …, θm) and X ∊ Rd, and suppose that the distribution of (X, θ) is given by a) P(θ = θi) = pi, 1 ≤ i ≤ m, and b) P{X < x/θ = θi} has a probability... View full abstract»

• ### Elimination of redundant operations for a fast Sobel operator

Publication Year: 1983, Page(s):242 - 245
| | PDF (982 KB)

Automatic image segmentation by edge detection techniques often involves recursive operations that incorporate redundant computations. Two methods for implementation of a fast Sobel operator are proposed, which eliminate a considerable amount of redundancy at the expense of increased storage capacity. Comparisons between the standard method and the proposed fast methods are included. View full abstract»

• ### Review of pseudoinverse control for use with kinematically redundant manipulators

Publication Year: 1983, Page(s):245 - 250
Cited by:  Papers (324)  |  Patents (1)
| | PDF (1423 KB)

Kinematically redundant manipulators have a number of potential advantages over current manipulator designs. For this type of arm, velocity control through pseudoinverses is suggested. Questions associated with pseudoinverse control are examined in detail and show that in some cases this control leads to undesired arm configurations. A method for distributing joint angles of a redundant arm in a g... View full abstract»
