Interference Control of Indoor Cognitive Radio Systems
… contour. This thesis investigates the aggregated interference power (AIP) in a broadcast TV system due to multiple transmitting secondary users (SUs). The COST-231 building pen- etration model is also used in this investigation to assess the bene t of re-using spectrum indoors. It is identi ed …

Interference control in language processing: the effects of age and working memory
… of the to-be-integrated concepts and deficits in interference control in working memory. Furthermore, emerging evidence implies that situation construction/simulation can be compromised for individuals with less working memory resources or when binding concepts (that is the basis for enriched and …

A Behavioral Study on the Adult Marmoset Interference Control in Spatial Working Memory
Interference control deficit in Working Memory (WM) is associated with neurodevelopmental disorders. The common marmoset (Callithrix jacchus) is an ideal non-human animal model for studying WM disorders. Previous studies of marmoset WM have used a touch-screen self-ordered sequencing task (SOST), …

Effects of music and dance training on executive functions in children
… for transfer to cognitive performance. A controlled experiment was used to isolate the causal influence of music and dance training on the executive functions of working memory, interference control, and task switching. Children between 6-9 years old were randomly assigned to music or …

The acute effects of varying intensities of treadmill walking exercise on cognition in persons with multiple sclerosis
… the greatest beneficial effects on executive control in persons with mild MS disability. However, the dose-dependent effects of varying intensities of treadmill walking exercise on this cognitive function are unknown. Such an investigation is critical for providing the final data for …

Interference Modeling And Control In Wireless Networks
… communication [64, 80, 77].</p> <p>A basis of interference control is the interference model which \emph{predicts} whether a set of concurrent transmissions may interfere with one another. Two commonly used models, the \textit{SINR model} and the \textit{radio-K model}, are thoroughly studied …

Performance study on a dual prohibition Multiple Access protocol in mobile Ad Hoc and Wireless Mesh networks
… surrounding environment that is susceptible to interference and noise. To minimize losses of data due to collisions, wireless networks need a mechanism to regulate the access on the transmission medium. Medium Access Control (MAC) protocols control access to the shared communication medium so …

Transient modulations of inhibitory control in children with ADHD: The effect of a single bout of physical activity
… were assessed while participants performed an interference control task following a bout of exercise or seated reading during two separate, counterbalanced sessions. Following a single bout of exercise, both children with ADHD and healthy match-control children exhibited greater response …

The effects of single bouts of aerobic exercise, videogame play, and exergaming on cognitive control
… and task performance indices of cognitive control were studied. Thirty-six young adults performed a modified flanker task during four separate, counterbalanced sessions, using a within-subjects design. Participants were trained on the flanker and gaming tasks prior to completing the …

Propagation prediction for PCS design in urban microwave channels
… microwave spectrum. This presents cochannel interference control problems which can be avoided with extensive propagation studies in both measurements and predictions. Currently, there is no readily available tool to predict propagation channels for the small coverage area that PCS operates …

Magnetic Cleanliness, Sensing, and Calibration for CubeSats
… We discuss the estimation of spacecraft self-interference and implement an informal magnetic interference control process. We present some simple ground testing strategies for magnetic screening of components and measurement of spacecraft self-interference. We evaluate the performance and …

Frequency selective surface (FSS) for cellular signals shelding
… proposes a frequency selective surface (FSS) for interference control causes by the proliferation of mobile devices. FSS is a periodic structure etched on a dielectric substrate which acts as a spatial filter. The proposed FSS is designed as a band-stop filter to attenuate the cellular signals …

Aerobic Fitness and Attentional Control in Preadolescent Children
… networks: alerting, orienting, and executive control (i.e., interference control). This task has conditions that require both smaller and larger executive components, and allows for the assessment of general versus selective influences of fitness on cognitive processing. Previous research on …

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 …

The effects of docosahexaenoic acid combined with supporting nutrients and physical activity on mobility and cognitive function in older women.
… was to conduct a randomised semi-blinded placebo controlled study exploring the effects of a high DHA multi-nutrient supplement and aerobic exercise, alone and in combination, on mobility and cognition in older women. One the novel aspects of the research conducted within the thesis is the use of …
