This thesis deals with the development of a time synchronization algorithm for underwater sensor networks. The ease of deployment and maintenance of wireless networks leaded this research to the use of an acoustic communication ...
Antenna array systems have a broad range of applications in radio frequency (RF) and ultra-wideband (UWB) communications to receive/transmit electromagnetic waves from/to the sky. They can enhance the amplitude of the input ...
En esta tesis se analizan las bases de la Tomografía de Impedancia Eléctrica (TIE) desde los aspectos de campos electromagnéticos, los electrodos y las propiedades eléctricas de los tejidos en seres vivos. Se analizan los ...
Current theories and mechanisms of nerve impulse propagation inside neurons do not give a satisfactory explanation to the nanoscale processes that occur inside the membrane. Propagation at the dendritic zones, and at the ...
The adherence to a healthy lifestyle plays a key role for increasing life expectancy and living better. The main habits of healthy lifestyle are: physical activity, diet and sleep quality. Nowadays, many people use a ...
In 1925, Lilienfeld patented the basic principle of field effect transistor (FET). Thirty-four years later, Kahng and Atalla invented the MOSFET. Since that time, it has become the most widely used type of transistor in ...
During the last decades, human beings have experienced a significant enhancement in the quality of life thanks in large part to the fast evolution of Integrated Circuits (IC). This unprecedented technological race, along ...
The number of applications that require the use of power converters has been continually increasing in the last years on account of environmental and economical concerns. The power to be processed by these converters has ...
Resonant Inductive Coupling Wireless Power Transfer (RIC-WPT) has been proven to provide very high power transfer efficiencies (above 80%) for moderate distances, and is hence foreseen as a key technology to enable wireless ...
