Language and conflict detection in the development of executive function
… EF, much remains unknown about how it develops. Conflict monitoring theory has emphasized the role of prefrontally-based conflict monitoring and detection mechanisms in the activation of control processes. In contrast, Vygotsky's sociocultural theory of development suggests that experience, …

Mode identification using stochastic hybrid models with applications to conflict detection and resolution
… and analyze realistic air traffic management conflict detection scenarios in a scalable, composable, multi-aircraft fashion is an extremely difficult endeavor. Accurate techniques for aircraft mode detection are critical in order to enable the precise projection of aircraft conflicts, and for …

Enabling Experimentation and Evaluation of xApp Direct Conflict Detection and Mitigation in Testbed
… (Near-RT RIC) can lead to resource allocation conflicts, particularly when xApps pursue overlapping or competing control objectives. This thesis presents a complete conflict manage- ment mechanism, implemented as part of the Conflict Mitigation (CM) component in Near-RT RIC, that includes both …

EXPLICITLY AWARE OF CONFLICT: CHALLENGING THE IMPLICIT CONFLICT DETECTION INTERPRETATION OF THE BASE-RATE NEGLECT TASK
Conflict reasoning problems cue two competing responses to the problem, requiring the reasoner to resolve the conflict; non-conflict problems cue the same response. The central claim of the conflict detection literature is that conflict is detected implicitly without explicit awareness. The goal of …

Onboard Aircraft Traffic Tracking Algorithm to Support Conflict Detection and Resolution using Multi-sensor Data Integration and Integrity Monitoring
… is also an excellent monitor for the detection of off-nominal position and velocity reports. Estimated baseline vectors that pass these integrity checks are advanced to the next stage, where ellipsoid uncertainty regions around each relative position vector are computed.</p><p>The …

Effects of Air Traffic Geometry and Conflict Alerting System Reliability on Pilots' Conflict Detection With Cockpit Display of Traffic Information
In Experiment 2, the difficult and easy conflict trials from Experiment 1 were replayed to a new set of pilots, now equipped with an imperfect automation detection alert, that provided them with three levels of predicted conflict risk, and occasionally made errors. Some pilots benefited from this …

Effects of Display Dimensionality, Conflict Geometry, and Time Pressure on Conflict Detection and Resolution Performance Using a Cockpit Display of Traffic Information
Finally, as time pressure and workload increased, performance issues arose that will need to be further investigated so that future display designs can accommodate pilots who will be multitasking in high time pressure environments.

Optimistic Partitioned Operation in Distributed Database Systems (Network Partitioning, Replicated Data, Consistency, Recovery, Fault-Tolerance)
… transactions to be processed in any partition. Conflict detection and resolution will then be performed when partitions are merged. Recently, an automatic conflict detection and resolution method based on serialization graphs has been proposed in the literature. It has been argued that the …

Supporting Coordination in Widely Distributed Cognitive Systems: The Role of Conflict Type, Time Pressure, Display Design, and Trust
… found that pilots were often unable to detect conflicts and thus failed to make informed and accurate decisions about proposed machine actions. Detection performance was particularly poor for conflicts related to clearance implementation, which were most likely to be missed if the automation …

Contributions to deconfliction advanced U-space services for multiple unmanned aerial systems including field tests validation
… described in this Thesis. With an emphasis on conflict detection and resolution features, the architecture is flexible, modular, and scalable. The UTM is designed to work without the need for human involvement, to achieve U-space required scalability due to the large number of expected …

Conflict and adaptation: Identifying the markers of cognitive control in the transition from wakefulness to sleep
… by investigating the effect of alertness on conflict monitoring. Conflict monitoring is the environmental scanning process by which the brain detects conflicting information and identifies the need for top-down behavioural control. Using a combined Go/NoGo and Go-left/Go-right paradigm, we …

Scalable and Broad Hardware Acceleration through Practical Speculative Parallelism
… to see if they are. If a task produces a conflict during execution, i.e., if it may violate a data dependence, then it is aborted and re-executed. This thesis proposes Chronos, a framework-based approach for building accelerators that use speculation to extract parallelism. Under Chronos, …

Integrating Imperfect Automated Aids Into a Multi -Task Situations
… and the threshold of the alert, affected both conflict detection and concurrent task performance. Automated aids with higher false alarm rates resulted in poorer concurrent task performance, as evidenced by higher tracking error and reduced working memory accuracy. Likelihood alerts did not …

Architectural support for commutativity in hardware speculation
… from limited concurrency because they detect conflicts at the level of reads and writes. By contrast, software speculation schemes can reduce conflicts by exploiting that many operations on shared data are semantically commutative: they produce semantically equivalent results when reordered. …

Learning and Reconstructing Conflicts in O-RAN
… (Near-RT RIC), known as xApps, may result in conflicting interactions. Each xApp can independently modify the same control parameters to achieve distinct outcomes, which has the potential to cause performance degradation and network instability. The current conflict detection and mitigation …

Evaluation of Perspective and Coplanar Cockpit Displays of Traffic Information to Support Hazard Awareness in Free Flight
… of pilots to detect and avoid air traffic conflict in a part-task flight simulation paradigm. Thirty certified flight instructors from the Institute of Aviation at the University of Illinois flew a series of trials using one of three cockpit display of traffic information (CDTI) formats. A …

Aircraft conflict analysis and real-time conflict probing using probabilistic trajectory modeling
… error become more problematic, automated conflict alerting systems have been proposed to help provide decision support and to serve as traffic monitoring aids. The problem of conflict detection and resolution has been tackled from a number of different ways, but in this thesis, it is …

Understanding Software Merge Conflicts for Java Programs
… the branches to integrate edits. However, merge conflicts can arise when edits overlap or interfere with each other. Resolving merge conflicts is challenging and tedious. Prior work proposed tools to detect and solve conflicts. However, many questions are still not fully investigated, such as …
