Thermoplastic use as labyrinth seals in rotating equipment is continuing to gain acceptance in the process industries. Presented in this paper is a discussion on thermoplastic use as a labyrinth seal material in centrifugal process compressors. Labyrinths made from engineering thermoplastics are used to improve efficiency, reliability, and installation time. An introduction to the polymer mater...

The paper presents an algorithm for planning the path of a mobile robot in a labyrinth. The algorithm uses an image, obtained by a camera. The algorithm processes the image to convert it into a matrix, presenting the labyrinth with obstacles and walls. Afterwards the algorithm finds the shortest path to a final target in the labyrinth. As opposed to the classical Dijkstra’s algorithm, the prese...

In this paper an artificial vision system for the analysis of the trajectory of an object is presented, which allows to solve a robotic labyrinth analyzing the routes of a moving object in the space. The prototype consists of a labyrinth with a unique solution at the center, so that regardless the position where a mobile object is placed, it is recognized and mapped to a coordinate system. Depe...

1. A new concept of endolymph flow in the vertebrate vestibular system is presented. This approach describes quantitatively the flow in the entire system of three semicircular ducts interconnected by the utriculus and the crus commune. This approach is quite distinct from the classical theory in which the labyrinth is generally conceived to consist of three separate duct circuits. 2. The presen...

We studied focusing in a two-dimensional metamaterial that was based on a labyrinth structure. We theoretically showed that the labyrinth-based metamaterial exhibits negative indices of refraction between 6 and 6.4 GHz. We experimentally studied the focusing effect by measuring electric field intensities on the output side of the metamaterial when the source was placed in front of the input sid...

The endolymphatic potential was recorded from various vestibular parts of the labyrinth from which the cochlea (in the case of guinea pigs) or the cochlea, lagena, and sacculus (in the case of pigeons) had been removed. This endovestibular potential of the isolated vestibule declined during anoxia and recovered after anoxia in the same manner as the endovestibular potential of the intact labyri...

The semicircular canal (SC) system of the inner ear detects head angular accelerations and is essential for navigation and spatial awareness in vertebrates. Because the bony labyrinth encloses the membranous labyrinth SCs, it can be used as a proxy for animal behavior. The bony labyrinth of dicynodonts, a clade of herbivorous non-mammalian synapsids, has only been described in a handful of indi...
