Terrain perception greatly enhances the performance of robots, providing them with essential information on the nature of terrain being traversed. Several living beings in nature offer interesting inspirations which adopt different gait patterns according to nature of terrain. In this paper, we present a novel terrain perception system for our bioinspired robot, Scorpio, to classify the terrain...

Pattern analysj s using syntacti c methods is discussed briefly to introduce the ideas of the linguistic nature of the attributes and of possi-bl e invariance properties versus usual geometrica] t ran sformations. A linguistic operator invariant for projec-ti ons from plane to plane is proposed and appli ed to the analysis of point patterns X. From knowled ge of the operator "result" or "attrib...

The northwestern part of the Kerman Cenozoic magmatic arc (KCMA) contains many areas with porphyry copper mineralization. In this research, we used the advanced space-borne thermal emission and reflection radiometer (ASTER) and Enhanced Thematic Mapper plus (ETM+) images of this region to map the distribution of hydrothermally altered rocks, based on their mineral assemblages. The spectral meas...

Introduction: Purkinje Cell (PC) output displays a complex firing pattern consisting of high frequency sodium spikes and low frequency calcium spikes, and disruption in this firing behavior may contribute to cerebellar ataxia. Riluzole, neuroprotective agent, has been demonstrated to have neuroprotective effects in cerebellar ataxia. Here, the spectral analysis of PCs firing in control, 3-acety...

Based on the accumulated data, FTIR spectroscopy seems to be a highly sensitive tool in cervical cancer diagnosis. We, therefore, employed this technique in a screening type of research here in Tehran. The purpose of this study was to look for the spectral pattern differences between normal and malignant cervix samples in Iranian women. Through formal and informal announcements, all gynecology ...

Interpreting spectral images requires comparing known patterns with input data (images) to identify which patterns are contained in the input data. In practice, however, it is hard to identify any pattern when the inaccuracy of input data is not slight. In this paper, we present a method for interpreting spectral images by using qualitative reasoning. First, we put forward a new concept called ...
