Performance Evaluation of Token Control Networks
… of a network access method, known as token control scheme, commonly used in loop networks. An exact analytical and empirical model are developed for the cases where exhaustive service and non-exhaustive service disciplines are used, respectively. Accuracies in the values of average network …

The Internet of things applied to command and control networks
… superiority and the ability to command and control people and things. This paper leverages the traditional systems engineering "'V" model as a framework to develop and analyze a concept for an Air Force command and control network. Methods and tools such as stakeholder analysis, hierarchical …

The contributions of posterior lateral temporal cortex to language and control networks
… an ongoing challenge. In recent years, the Controlled Semantic Cognition framework has offered an account of the neural correlates of representation and control of meaningful information. The context-independent storage of semantic representations is subserved by the bilateral anterior …

A functional imaging study of the relationship between the Default Mode Network and other control networks in the human brain
… is a large-scale brain network implicated in the control and monitoring of internal modes of cognition. The aim of this research was to investigate DMN function and its relationship to other large-scale cognitive control networks through functional connectivity analysis and analysis of combined …

Functional Connectivity Within the Dynamic Pain Connectome Underlying Inter-Subject Differences in Acute and Chronic Pain
… brain circuitry, specifically in and between networks which are involved with pain processing and coping. Clinically, the degree of abnormality across these networks may underlie the level of pain experienced by chronic pain patients. Thus, this thesis investigated how functional communication …

A TRANSPORT MECHANISM FOR REALTIME APPLICATIONS
… of any industry associated with process control, manufacturing and multimedia. Realtime aspect is essential to facilitate the coordination among the multitude of processes in such industries. There are many communication mechanisms existing for real time data acquisition and processing. …

Segurança em redes definidas por software :autenticação, controle de acesso e consistência com plano de controle eficientemente distribuído
The control distribution in Software-Defined Networks improves the security, performance and scalability of the network. However, distributed control introduces consistency challenges into the network global view. In this work, we present the main security threats to the software-defined networks, …

Increasing Screen Exposure Time Harms Inhibitory-Control Network in Developing Children: A Two Years Follow-up of the ABCD Study
… may delay the development of the inhibitory control networks in children, who are vulnerable to immediate reward-orientated tendencies and not yet capable of controlling their impulsivity. Therefore, it was hypothesized that as children become more exposed to screens, the development of the …

Network-simulation-based evaluation of smart grid applications
… power grid was, but a complicated network of networks. That greatly increases the security concerns, ranging from hackers who gain access to control networks or create denial-of-service attacks on the networks themselves, to accidental causes, such as natural disasters or operator errors. …

A Synchronous Distributed Digital Control Architecture for High Power Converters
… multiple functions. Due to these properties, the control algorithm and its implementation are challenging, and a different approach is needed to avoid customized solutions to every application while still having reliable sensor measurements and converter communication and control. This thesis …

Ready for Action! When the Brain Learns, Yet Memory-Guided Behavior Does Not Follow
… demonstrated that fronto-parietal attention and control networks are critical for memory-guided behavior. Study 3 empirically validated this working model, using time-frequency source localization. Specifically, I showed that, in addition to fronto-parietal networks, memory-guided behavior is …

Brain Network Connectivity in Anaesthesia and Disorders of Consciousness
… in default mode, salience, and frontoparietal control networks were found to correlate with the cortical distribution of parvalbumin-expressing GABAergic interneurons. Using the same dataset, Experiment 3 identified a relationship between structural and functional networks in connections …

Distributed LQR control of multi-agent systems
The thesis develops optimal control methods for designing distributed cooperative control schemes in multi-agent networks. First, the model of a completely connected multi-agent network is presented, consisting of identical dynamically decoupled agents controlled by a centralized LQR (Linear …

Modeling and mitigating cascading failures in interdependent power grids and communication networks
… infrastructures are organized in the form of networks, which are dependent on one another. A particular example is the power grid and the communication network used to control the grid. While this dependence is beneficial during normal operation, as it allows for more efficient operation, it …

Stability and Control in Complex Networks of Dynamical Systems
… LASER cooling and plasma stability. These large networks are often modeled to have a completely random (Erdös-Rényi) or semi-random (Small-World) topologies. The former model is often used due to mathematical tractability while the latter has been shown to be a better model for most real life …

Neuroimaging and neurocognitive assessment of PTSD and MDD in a South African community setting
… brain dysfunction, relative to healthy controls, and these effects will be amplified in patients with both disorders. Methods: This dissertation was undertaken within the Drakenstein Child Health Study, a study exploring child health determinants in mother-infant dyads from the …

Intrinsic functional brain connectivity in South African methamphetamine users undergoing inpatient treatment, with or without additional cognitive training
… adjunct to inpatient treatment of MUD. Healthy controls (HC, N = 25) were compared to two MUD groups, one receiving treatment as usual (TAU, N = 17), and one receiving additional cognitive training (CT, N = 24) in the form of a modified version of the ‘N-back' task (C-Ya). This task was also …
