Clinoptilolite was investigated for the removal of Cu(II) ions from industrial leachate. Adaptive neural fuzzy interface system (ANFIS) was used for modeling the batch experimental system and predicting the optimal input values, that is, initial pH, adsorbent dosage, and contact time. Experiments were studied under laboratory batch and fixed bed conditions. The outcomes of suggested ANFIS model...

Although current photorealistic rendering techniques can produce very impressive images, the rendered objects are often too clean and shiny. Thus, the resulting images look unnatural. This paper proposes a physically-based model to simulate the appearance of patinas on ancient Chinese bronzes. Buried in the soil for thousands of years, many patinas are found on the surface of ancient bronzes as...

A new species of Acroperus Baird, 1843 (Cladocera: Chydoridae) is described based on the material from Lake Tana, Ethiopia and two water bodies in Eastern Cape, Republic of South Africa. In Africa, Acroperus africanus sp. nov. had a chance to be confused by previous authors with Palearctic A. harpae (Baird, 1834) and A. angustatus Sars, 1863, but it could be easily distinguished from the latter...

This chapter provides a computational analysis of the variation in the pronunciation of some Tibetan numbers. In Tibetan, the names for numbers greater than ten are formed by concatenating the word for a number less than ten with the word that means ‘ten.’ We refer to these combinations as “compound numerals.” In particular, numbers from eleven to nineteen are formed by prefixing [ > dZu] ‘ten’...
