Self-Optimizing Control and Passive Velocity Field Control of Intelligent Machines

This paper uses information theory to investigate the utility of alternative Command and Control (C2) structures and strategies. Specifically we use information theoretic metrics complexity, entropic drag and evolutionary entropy. Complexity measures the amount of information required to fully express a situation. Entropic drag measures the rate at which situational information becomes obsolete...

We present the Optimizing Control Variate (OCV) estimator, a new estimator for Monte Carlo rendering. Based upon a deterministic sampling framework, OCV allows multiple importance sampling functions to be combined in one algorithm. Its optimizing nature addresses a major problem with control variate estimators for rendering: users supply a generic correlated function which is optimized for each...

Controlling dynamics of a network from any initial state to a final desired state has many applications in different disciplines from engineering to biology and social sciences. In this work, we optimize the network structure for pinning control. The problem is formulated as four optimization tasks: i) optimizing the locations of driver nodes, ii) optimizing the feedback gains, iii) optimizing ...

The optimizing-adaptive control problem arises in applications where the desired behavior is not speci ed explicitly, but instead, an objective function of the plant behavior and the unknown plant itself is to be optimized. In these cases, the control task involves the explicit determination of the optimal behavior and the control action to achieve that behavior. The di culty with this problem ...

South African Centre for Epidemiological Modelling and Analysis (SACEMA), Stellenbosch, South Africa Correspondence to [email protected] Abstract The Joint United Nations Programme on HIV and AIDS (UNAIDS) has embraced an ambitious global target for the implementation of treatment for people living with HIV. This 90-90-90 target would mean that, by 2020, 90% of all those living wit...

BACKGROUND Wide local excision (WLE) of anorectal melanoma is associated with a high incidence of local recurrence. There is a paucity of literature on adjuvant radiation in this malignancy. AIM To identify the optimal method of local treatment in anorectal melanoma. SETTINGS AND DESIGN Retrospective study in a tertiary cancer centre. MATERIALS AND METHODS Records of 63 patients who prese...

We study unreliable serial production lines with known failure probabilities for each operation. Such a production line consists of a series of stations; existing machines and optional quality control stations (QCSs). Our aim is to decide on the allocation of the QCSs within the assembly line, so as to maximize the expected profit of the system. In such a problem, the designer has to determine ...

This is the second part of a two-part paper on the design of an intelligent controller for a class of exercise machines. The control objective is to cause the user to exercise in a manner that optimizes a criterion related to the user’s mechanical power. The optimal exercise strategy is determined by an a priori unknown biomechanical behavior, called the Hill surface, of the individual user. Co...
