KINEMATICS INVESTIGATIONS OF BULK MATERIAL MOTION IN SCREW SIEVE. PART I

Sieve Methods Lecture Notes, Part I the Brun-hooley Sieve

A sieve is a technique for bounding the size of a set after the elements with “undesirable properties” (usually of a number theoretic nature) have been removed. The undesirable properties could be divisibility by a prime from a given set, other multiplicative constraints (divisibility by a perfect square for example) or inclusion in a set of residue classes. The methods usually involve some kin...

Motion Modeis: Part I

I. MOTION This section describes two types of models. The first performs simple motion measurement. The second integrates motion spatially to obtain a more global percept. . Motion perception is locally ambiguous as illustrated in figure (1). Short-range motion suffers from the aperture problem while long-range motion has the correspondence problem (long range motion will be covered in the next...

Internal Kinematics of Spiral Galaxies in Distant Clusters Part I

We introduce our project on galaxy evolution in the environment of rich clusters aiming at disentangling the importance of specific interaction and galaxy transformation processes from the hierarchical evolution of galaxies in the field. Emphasis is laid on the examination of the internal kinematics of disk galaxies through spatially resolved MOS spectroscopy with FORS at the VLT. First results...

Visual Kinematics I. Visual Space Metric in Visual Motion

Visual deformations of moving objects are traditionally attributed to visual mechanisms, such as spatiotemporal summation and visual masking, that transform the distribution of color/brightness in visual space. This paper presents experimental proof that in addition to these distributional transformations, the metric of visual space itself changes in visual motion, Under steady fixation conditi...
