The Rod and Frame test measures an individual’s subjective assessment of visual vertical and horizontal in the presence of a surrounding tilted frame. Attention has focused upon the effects of the surrounding frame upon spatial accuracy (Spatial Frame Effect). We have investigated if the tilted frame also affects the time that subjects take to make the alignment (Temporal Frame Effect). Results...

in this paper, we characterize multiresolution analysis(mra) parseval frame multiwavelets in l^2(r^d) with matrix dilations of the form (d f )(x) = sqrt{2}f (ax), where a is an arbitrary expanding dtimes d matrix with integer coefficients, such that |deta| =2. we study a class of generalized low pass matrix filters that allow us to define (and construct) the subclass of mra tight frame multiwav...

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...

This paper investigates the effectiveness of floating breakwaters consisting two barges (L-shape), three (U-shape), four (barge frame), and conventional single breakwater. The different spatial layouts have sheltered internal gaps/moonpools when compared to their counterparts. motions these in wave transmission motion reduction protected bodies are evaluated. study is conducted based on a subsy...

In this paper, we characterize multiresolution analysis(MRA) Parseval frame multiwavelets in L^2(R^d) with matrix dilations of the form (D f )(x) = sqrt{2}f (Ax), where A is an arbitrary expanding dtimes d matrix with integer coefficients, such that |detA| =2. We study a class of generalized low pass matrix filters that allow us to define (and construct) the subclass of MRA tight frame multiwa...

This paper deals with several aspects of epimorphisms in the category MFrm of metric frames and contractive homomorphisms. In particular, it is shown that (i) the epicomplete metric frames are uniquely determined by the power-set lattices of sets, (ii) episurjective is the same as Boolean, (iii) a metric frame has an epicompletion iff it is spatial, and (iv) the subcategory of epicomplete L in ...

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...
