Cayley-Dickson Loops
<p>In this dissertation we study the Cayley-Dickson loops, multiplicative structures arising from the standard Cayley-Dickson doubling process. More precisely, the Cayley-Dickson loop <em>Q<sub>n</sub></em> is the multiplicative closure of basic elements of the algebra constructed by <em>n</em> …

Higher-Order Lucas Sequences and Dickson Polynomials
… that L_k = D^M_k where D^M_k is a higher-order Dickson polynomial. We first examine the cases where M has projective orders 3, 4, and 6. For the order 3 case, we find that M has entries in, at worst, a quadratic extension of F. This is also true for the orders 4 and 6, but requires a restriction …

ANALYSIS, OPTIMIZATION, AND PRACTICAL DESIGN OF A SPLIT-PHASE DICKSON SWITCHED CAPACITOR CONVERTER FOR HIGH CURRENT APPLICATIONS
… which addresses charge redistribution in the Dickson SCC by controlling the charging and discharging of the flying capacitors, such that the equivalent branch voltages line up when switching occurs. In adapting the split-phase Dickson SCC topology for high-current applications, two significant …

Analysis and design of high power density resonant switched-capacitor converters
… This work proposes a resonant, voltage step-up Dickson SC converter. A single inductor is utilized to achieve zero current switching of all transistors, which allows for high switching frequency and high conversion efficiency. A split-phase control scheme is used in order to eliminate the …

Analysis of soft charging switched capacitor power converters
… topologies can support soft-charging, and the Dickson charge pump is selected for the continued development of soft-charging control. The specifics of adapting soft-charging to the Dickson topology are accomplished through a loop-by-loop analysis to modify the phase structure and charge vector …

Biological and chemical monitoring of three streams in the area of Blacksburg, Virginia
… in the three streams investigated. The Cairns-Dickson DI<sub>T</sub> diversity index was applied to two trophic levels of aquatic organisms and the results were compared to ascertain whether this diversity index is applicable to all levels of the trophic\structure or of greater use for a …

Operation and analysis of high-voltage-gain dc-dc converters with voltage multipliers
… used in this research is based on a modified Dickson charge pump voltage multiplier stage, and this family has been studied in discontinuous conduction mode (DCM). The second family relies on a non-inverting or inverting diode-capacitors voltage multiplier stage and has been proposed in both …

A Hybrid Switched-Capacitor Converter for Capacitive Wireless Power Transfer in Biomedical Applications
… In the proposed thesis, a capacitively isolated Dickson converter, a type of hybrid switched capacitor converter, will be investigated to determine if it can be used to safely, efficiently, and in a small package deliver power to biomedical implants.

Novel Topology for Capacitively Isolated Switched Capacitor Converter
… of the Cockcroft-Walton generator into the Dickson converter framework, the proposed design seeks to leverage the inherent advantages of switched-capacitor converters—such as compactness, lightweight design, and higher efficiency at low to moderate power levels—over traditional magnetic …

Creating Focused Occupational Therapy Interventions for Clients with Heart Failure in Skilled Nursing Facilities
… readmission rates may be due to the cognitive (Dickson, Tkacs, and Riegel, 2007), psychosocial (Halliday, 2010), and lifestyle barriers (Maeda, Shen, Schwarz, Farrell, & Mallon, 2013) HF clients face. However, interventions in the SNF tend to emphasize activities of daily living (ADLs) and …

Octonions and the Exceptional Lie Algebra g_2
… call the Fano Plane. Next we explain the Cayley-Dickson construction, which exhibits the octonions as the set of ordered pairs of quaternions. This approach parallels the realization of the complex numbers as ordered pairs of real numbers. The rest of the thesis is devoted to following a paper by …

Five key themes emerged from the consistently reported responses. A coach approach (a) builds on the foundation of licensing …
