Plastic containers are a major source of pollution and contribute to greenhouse gases. Many plastic embossed with small symbol three arrows forming triangle number in the middle triangle. As part US online study, we assessed meaning this symbol. Of 808 respondents presented visual image three-arrow symbol, 81.3% reported (incorrectly) that indicated item could definitely be recycled 16.3% it pr...

The Information Systems on the Web comply with the semiotic triangle. In the COEUR-SW triangle, a concept in a Universe of Thought is related to an uttered symbol in a Universe of Language, the symbol is related to a referent in a Universe of Structure, and the referent is related back to the concept. The concept, the symbol and the referents are related to a context in the Universe of Discours...

In this paper, we propose robust and efficient signal detection and symbol timing synchronization schemes applicable to preamble based wireless systems such as WLAN and WMAN-OFDM. The signal detection algorithm is based on detecting the increase in energy at the beginning of the preamble. For symbol timing synchronization, instead of using conventional normalized timing metric, a new algorithm ...

Contemporary recognition systems use various methods of symbol recognition and post-processing methods designed for enhancing the quality of text recognition. For some recognition problems it may be difficult to create an adequate dataset for training symbol recognizers, so several symbol recognizers are used to ensure better performance. In this paper the concept of recognizer relevance is int...
