Abstract A band-enhanced and low-profile tightly coupled array (TCA) with inductive windows (IWs) split rings (SRs) is proposed in this paper. The IW cell placed between the antenna plane ground consists of four parallel strips which introduces inductance to move resonance frequency caused by out operating band. Moreover, SR specially designed thin thick wide-angle impedance matching (WAIM) sup...

The integration of an Inertial Navigation System (INS) and the Global Positioning System (GPS) is common in mobile mapping and navigation applications to seamlessly determine the position, velocity, and orientation of the mobile platform. In most INS/GPS integrated architectures, the GPS is considered to be an accurate reference with which to correct for the systematic errors of the inertial se...

Cognitive ecology is a term that has been used in environments that are more tightly coupled and purposespecific than environments of everyday life. In this paper I consider cases from a cognitive ethnography of older adults. These cases show the analytical use of understanding the diachronic and synchronic cognitive ecology in which cognitive processes of everyday life occur. Specifically I di...
