Predictive and reactive control mechanisms involved in object manipulation
… looked to investigate some of the predictive and reactive mechanisms supporting manipulation in the context of object lifting. When lifting an object, weight is estimated based on learned associations between the visual features of objects (e.g. size, material) and their weight. However, …

Reliable goal-directed reactive control of autonomous mobile robots
This dissertation demonstrates that effective control of autonomous mobile robots in real-world environments can be achieved by combining reactive and deliberative components into an integrated architecture. The reactive component allows the robot to respond to contingencies in real time. …

Analysis of adaptive reactive control systems for autonomous mobile robots
… presents techniques developed for the robust reactive control of autonomous mobile robots navigating in complex environments. Traditional approaches have adopted a top-down perspective by focusing on the reasoning part of path-planning. In contrast, this thesis tackles planning from a …

Investigation of Binary Mixtures of N-Butanol and Biodiesel in Reactive Control Compression Ignition
<p>In this study the Reactive Controlled Combustion Ignition (RCCI) obtained by port fuel injection (PFI) of n-butanol and direct injection (DI) of biodiesel was compared with an in cylinder directly injected blend of n-butanol and biodiesel with the same mass ratio of n-butanol to biodiesel which …

The Mechanisms of Proactive Interference and Their Relationship with Working Memory
… literature, proposing two general types of PI control mechanisms that occur at different time points: proactive control (involves preparation in advance of the interference) and reactive control (occurs after interference occurs). This thesis proposed that among these four functions involving …

An EEG Source-Space Analysis of the Neural Correlates Underlying Self-Regulation
<p>Self-regulation is the cognitive process of controlling our thoughts and behaviors to be aligned with our goals. This process is used in many different contexts and has been associated with contributions from several brain regions. This research aimed to investigate differences in four …

Viewpoint-Aware Task Planning and Model Predictive Control for Applications in Videography and Multi-Target Tracking
… to combine high level planning with low level reactive control to solve a variety of viewpoint-constrained target following tasks. In the scenarios we consider, a team of tracking agents is desired to gain some sort of visual information about one or more target agents. A high level planning …

Domain-general control mechanisms underlying stopping of thought and action
… by preventing the unwanted response, or reactively, by cancelling the already initiated response. Previous studies have shown that a)action stopping is mediated via distinct fronto-sub-cortical interactions that achieve proactive and reactive control, b) stopping actions and thoughts …

Situational and individual factors of reactive cognitive control: examining feedback and motivation
… of feedback on a cognitive task that encouraged reactive cognitive control. I hypothesized that the presence of feedback would facilitate faster responses. I also hypothesized that cognitive intrinsic motivation, one’s disposition towards exerting cognitive effort, would be related to reactive …

Evaluating the cognitive benefits associated with an acting intervention: A brain-behavior framework
… to pre-intervention and an active control group. Within this context, we pursued two-interrelated lines of investigation, presented in Chapters 1 and 2 respectively. In Chapter 1, we postulated that older adults would show improvements in various aspects of executive function and …

Analysis of epidemiological models for disease control in single and multiple populations under resource constraints
… of disease dynamics. Examples range from reactive control measures, where the resources used to manage the epidemic in real time may be limited to prophylactic control measures such as deployment of genetically resistant plant varieties, which may lead to economic trade-offs. In such …

Adaptive sampling in autonomous marine sensor networks
… for real-time adaptive and cooperative control of autonomous sensor platforms in a marine sensor network is described in the context of the autonomous oceanographic network scenario. This architecture has three major components, an intelligent, logical sensor that provides high-level …

Simulation and Assessment of Long-Term Stormwater Basin Performance under Real-Time Control Retrofits
The use of real-time control (RTC) as an adaptation technique for improving existing stormwater systems has been gaining attention in recent years for its ability to enhance water quality and quantity treatment. A case study RTC retrofit of seven existing detention basins was simulated for a small …

A performance analysis of a modified leaky bucket mechanism
Preventive congestion control is more effective and widely used than reactive control. It is usually implemented in two ways: Connection Admission Control (CAC) and Usage Parameter Control (UPC). Leaky bucket (LB) is a typically used UPC mechanism. A traditional LB can either police a bursty …

Examining the boundary conditions between cognitive control and interference derived from stimulus-based and response-based conflict
Cognitive control is a broad construct that defines a set of processes involved in maintaining task goals in response to interference. Working memory capacity (WMC) is a similarly defined construct that shares many overlapping functions with cognitive control. The studies presented used controlled …

Unified Control for the Permanent Magnet Generator and Rectifier System
… Since the generator and the rectifier can be controlled simultaneously, it would be very desirable to develop a unified control. With this unified control, the boost inductors between the PMG and rectifier is eliminated, which significantly reduce the volume and the weight of the whole system …

Cognitive control in high and low suggestible individuals
The current work aimed to investigate cognitive control use in high and low hypnotically suggestible individuals in the context of the Dual-Mechanisms of Control Framework (Braver, 2012), to determine whether the differences in suggestion response are explained by the type of cognitive control …

Design of novel timing paradigms for investigation and rehabilitation of predictive and reactive postural response for hemiparetic stroke
… and understanding of timing effects in balance control may contribute to refine balance retraining paradigms for hemiparetic stroke. This thesis opens with a review on predictive and reactive modes of balance control. The initial review concludes there is unexplored potential in predictive …

THE DEVELOPMENT OF COGNITIVE CONTROL DURING CHILDHOOD: A NEUROCOGNITIVE PERSPECTIVE
… complete a goal – a concept known as cognitive control. Research has shown that cognitive control develops rapidly over the first decade of life. One of the key control-related developments during childhood is the transition from a heavy reliance on in-the-moment and as-needed control …

Accounting information system in the water industry : The case of cost management.
… processes are central to the water sector. The control or governing ideas within which cost management takes place are the two major concerns of this thesis. These two issues were explored in a case study of the General Organisation for the Greater Cairo Water Supply, focusing specifically upon …
