Planar detection using modified expectation maximization
… proposal of a Modified Expectation Maximization (MEM) algorithm. The MEM algorithm presented replaces the traditional maximization step with an optimization based maximization step or a Kalman Filter based maximization step. In addition to this, recommendations are provided to reduce the number of …

In-transit urbanism : the landscape of logistics and the time present
Upon arrival in Memphis by air, a sign welcomes passengers to "Memphis - America's Distribution Center", a reflection of one's place in the city, and the country. Rather than a romantic reflection of the cultural heritage of the city with Elvis Presley and B.B. King, the statement places passengers …
