In cellular telephones, RF power amplifiers consume a significant part of the total phone current. Reducing the average PA current will extend battery life. In GSM systems the handset is commanded by the base station to transmit at power levels lower than full power much of the time. A Doherty...
The number of drones and genetic diversity among drones are
essential components to a well mated queen. Varroa destructor
preferentially parasitizes drone brood, and is thought to be
responsible for the loss of feral populations that once provided
additional drones for honey bee mating areas. It is necessary to
use...
The ulnar collateral ligament (UCL) is the primary restraint against valgus forces at the elbow. This structure cannot support the entire load placed upon the medial elbow during overhand throwing motions such as pitching a baseball. In this study we measured the contributions that different muscle groups make to the...
Large-scale engineering systems provide important functions and at the same
time address serious concerns to human society. Because of the complexity and
resources involved, the development of these systems is currently a challenging
undertaking. In this work, an axiomatic design approach, based on Suhs axiomatic
design theory, and combined with...
The long-term goal of the research project initiated with this thesis is the development of lead-free, fully-transparent ferroelectric devices, such as ferroelectric capacitors or ferroelectric-gate field-effect transistors. Ferroelectric materials exhibit spontaneous polarization with the application of an external electric field, which is persistent upon removal of the applied field, and...
