In recent years, there has been increasing interest in interval analysis. Thanks to numbers, many real world problems have modeled and analyzed. Especially, complex intervals an important place for interval-valued data interval-based signal processing. this paper, firstly we introduce the notion of a sequence present spaces I(w) I(l_{p}), 1≤p

Nomenclature SF a , SFx a , SF y a , SFz a = specific force acceleration vector (sensed by accelerometers) and components in frame B B = sensor (body) coordinate frame aligned with strapdown inertial sensor axes 1 m B  = frame B orientation at computer cycle 1 m  () Bt = frame B orientation at time t k r c = combination, k elements selected from a set of r elements without regard to the order...
