the aim of this paper is to establish a fuzzy version of the dualitybetween domains and completely distributive lattices. all values aretaken in a fixed frame $l$. a definition of (strongly) completelydistributive $l$-ordered sets is introduced. the main result inthis paper is that the category of fuzzy domains is dually equivalentto the category of strongly completely distributive $l$-ordereds...

The use of spatial relational terms requires the selection of a reference frame and the construction of a spatial template. The reference frame divides up space, indicating above/below, front/ back, and left/right directions. Spatial templates are applied to reference frames and define regions in space that correspond to good, acceptable, and bad uses of particular spatial relations. In two exp...

In this paper, we propose OFDMA/TDD/MIMO system with spatial scheduling, showing frame structure and control procedures to achieve the proposed system. The frame structure includes all functions required for spatial scheduling in a subband of 200kHz and in a frame time of 2.5ms. We show that the frame structure can be a realistic solution to achieve spatial scheduling on subband basis. From the...

The process of describing an object's location relative to another object results in ambiguity. How do people handle this ambiguity? The present studies examined spatial language processing when use of different reference frames results in ambiguity. We investigated whether electrophysiological (ERP) measures of cognitive processing may elucidate underlying reference frame processing; in partic...

Visual attention prioritizes information presented at particular spatial locations. These locations can be defined in reference frames centered on the environment or on the viewer. This study investigates whether incidentally learned attention uses a viewer-centered or environment-centered reference frame. Participants conducted visual search on a monitor laid flat on a tabletop. During trainin...

Spatial navigation is an essential human skill that is influenced by several factors. The present study investigates how gender, age, and cultural background account for differences in reference frame proclivity and performance in a virtual navigation task. Using an online navigation study, we recorded reaction times, error rates (confusion of turning axis), and reference frame proclivity (egoc...
