This paper describes a drawing system that incorporates two novel interaction techniques based on analogies to physical tools. Power tools add limited autonomy in the form of rota...
Commodity virtual machine monitors forbid direct access to I/O devices by untrusted guest operating systems in order to provide protection and sharing. However, both I/O memory ma...
In this paper, we study power allocation (PA) in a single-relay OFDM system with limited feedback. We propose a PA scheme that uses a codebook of quantized PA vectors designed offl...
The efficient solution of large systems of linear equations represented by sparse matrices appears in many tasks. LU factorization followed by backward and forward substitutions i...
In this letter the performance limits and design principles of rateless codes over fading channels are studied. The diversity-multiplexing tradeoff (DMT) is used to analyze the sys...
