Studies of goal directed movements
The principles underlying the production of goal directed movements are largely unknown, as evidenced by the lack of artificial systems matching the real-world performance of biological organisms. The ability to transform in real time a vaguely defined goal (skiing downhill) into a detailed motor …

Infants' Understanding of Goal Directed Behavior
As adults, we interpret the actions of others as directed towards goals and we use that goal information to help make sense of others' actions. Infants as young as 5 months of age understand some of the repeated actions of others as directed toward the goal of obtaining a specific object (Woodward, …

Goal-directed qualitative reasoning with partial states
… on all choices, regardless of specific task goals. It reasons with completely described states and explores every (ambiguous) future of each.

Data structure repair using goal-directed reasoning
Software errors, hardware faults, and user errors can cause data structures in running applications to become damaged so that they violate key consistency properties. As a result of this violation, the application may produce unacceptable results or even crash. This dissertation presents a new data …

Biologically inspired goal directed navigation for mobile robots
This project involved an investigation into low-cost navigation of mobile robots with the aim of creating and adaptive navigation system inspired by behaviour seen in animals. The navigation module developed here would need to be able to successfully localise a robot and navigate it to a defined …

Robust, goal-directed plan execution with bounded risk
There is an increasing need for robust optimal plan execution for multi-agent systems in uncertain environments, while guaranteeing an acceptable probability of success. For example, a fleet of unmanned aerial vehicles (UAVs) and autonomous underwater vehicles (AUVs) are required to operate …

Integer overflow discovery using goal-directed conditional branch enforcement
We present a new technique and system, DIODE, for automatically generating inputs that trigger overflows at memory allocation sites. DIODE is designed to identify relevant sanity checks that inputs must satisfy to trigger overflows at target memory allocation sites, then generate inputs that …

Reliable goal-directed reactive control of autonomous mobile robots
… produces behavior which is reliable and goal-directed, yet reactive to contingencies, in the face of noise, limited computational resources, and an unpredictable environment. The system described in this dissertation has been used to control three real robots and a simulated robot …

Preserving Sequential Order: Goal-directed Processing And Social-cognitive Consequences
… preserved in memory under different processing goals or objectives, and (b) the implications of this for social judgment. The processing objectives of 'impression formation' and 'recall' were employed in all three studies (along with 'no-goal' control groups in Studies 2 and 3). In Study 1, …

How Want vs Need Self-Talk Facilitates Goal-Directed Behavior
… temptations or striving toward long-term goals. When attempting to exert self-control, the way people address themselves (e.g., self-talk) is important. This study examined how self-talk strategies want and need affected behavioral self-control outcomes in a temptation situation using a 2 …

Bio-mechanical characterisation of synergistic muscle control in goal directed movements
The generation of skilled movement requires the coordinated activation of muscles to produce precise muscle forces and joint torques. The co-ordination of muscles, acting on multi-joint limbs and characterised by highly non-linear dynamics, requires significant computational effort. The synergistic …

Goal-directed planning and plan recognition for the sustainable control of homes
The goal of this thesis is to design an autonomous control system for the sustainable control of buildings. The control system focusses on satisfying three goals to encourage and facilitate a more sustainable lifestyle for the future: sustainability, comfort, and convenience. First, the system must …

Goal-Directed Systems Testing: Automated Execution of Intelligently Generated Cyber Attack Plans
… adversary could attempt to achieve a high-level goal [2]. Built around observed adversarial tactics, techniques, and procedures identified in the ATT&CK Matrix [3], MITRE’s CALDERA is a robust automated, post-compromise, adversary emulation framework which allows users to autonomously execute …

GDI: (Goal Directed Interface): An intelligent, iconic, object-oriented interface for office systems
This dissertation presents the GDI (Goal Directed Interface) approach to the user interface for office systems. The primary objectives of the approach are to create an interface that (1) requires little user training and (2) tries to perform higher level task activities (ex. 'schedule a meeting') …

Multiplexed representations of uncertainty by mouse pulvinar-prefrontal projections during goal-directed behaviors
… and action is a central component of learned, goal-directed behavior. Even during ongoing sensory-motor processing, our sensory landscape is fltered through our prior expectations and ongoing goals. This active perceptual process hinges on a distributed network of cortical and subcortical …

Age-dependent effects of chronic amphetamine on prelimbic-nucleus accumbens circuit function and goal-directed behavior
… abnormalities in the reward circuit function and goal-directed behavior. Using a rat model, this hypothesis was tested with three specific aims: (1) to investigate the ontogeny of this LTD function (Experiment 1), (2) to assess the effect of adolescent and adult amphetamine on HFS-induced LTD in …

Is metabolism goal-directed? Investigating the validity of modeling biological systems with cybernetic control via omic data
… reactions in terms of dynamic "metabolic goals." This approach contrasts starkly with purely mechanistic descriptions of metabolic regulation which seek to explain metabolic processes in high resolution — a clearly daunting undertaking. Over a span of three decades, cybernetic models have …
