Mean kinetic energy distribution in finite-size wind farms: A function of turbines' arrangement

Varun Sharma, Marc Calaf Bracons, Roberto Torres Sánchez

In this work the redistribution and recovery of mean kinetic energy in a realistic, finite size wind farm is studied for neutral atmospheric boundary layer conditions. Five different wind farm configurations, with different wind turbine arrangements, are c ...

A Low Profile UWB Antenna for Wearable Applications: The Tripod Kettle Antenna (TKA)

Anja Skrivervik, Roberto Torres Sánchez, Jovanche Trajkovikj, Dea Dorina Cara

A new low profile ultra-wideband (UWB) antenna for wearable applications is presented. Its structure is derived from the quadripod kettle antenna (QKA) [1], and is called tripod kettle antenna (TKA). The proposed antenna is very well suited for wearable ap ...
