The goal of this research is to predict total stock market index of Tehran Stock Exchange, using the compound method of ARIMA and neural network in order for the active participations of finance market as well as macro decision makers to be able to predict trend of the market. First, the series of price index was decomposed by wavelet transform, then the smooth's series  predicted by using...

Thermoplastic polyurethane (TPU)/clay nanocomposites were prepared via a melt-compounding method using ester type TPU and two different modified organoclays (Cloisite 30B and Cloisite 15A) in different contents. The Effects of the chemical structure and content of the nanoclays on the thermal degradation and mechanical properties of TPU were also investigated. The effect of structural modificat...

Abstract In this paper, we present a use of XML and relational database for developing and maintaining Japanese linguistic resources. In languages that do not provide word delimitation in texts (e.g. Chinese and Japanese), consistent delimitation definition of words in a lexicon is a critical issue to build POS tagged corpora. When we change the definition of word delimitation in the lexicon, w...

We present and characterize a sequential angular compounding method for reducing speckle contrast in optical coherence tomography images of paint layers. The results are compared with postprocessing methods, and we show that the compounding technique can improve the speckle contrast ratio in B-scans by better than a factor of 2 in exchange for a negligible loss of resolution. As a result, image...

Ultrasound images are very noisy. Along with system noise, a significant noise source is the speckle phenomenon, caused by interference in the viewed object. Most past approaches for denoising ultrasound images essentially blur the image, and they do not handle attenuation. Our approach, on the contrary, does not blur the image and does handle attenuation. Our denoising approach is based on fre...

William Snyder Languages differ in the mechanisms they provide for combining existing words into new, “compound” words. This chapter will focus on two major types of compound: synthetic -ER compounds, like English dishwasher (for either a human or a machine that washes dishes), where “-ER” stands for the crosslinguistic counterparts to agentive and instrumental -er in English; and endocentric b...

Polymeric nanocomposites (PNC) are binary mixtures of strongly interacting, inorganic platelets dispersed in a polymeric matrix. For full exfoliation, the thermodynamic miscibility is required. There are three basic methods of organically-modified clay dispersion that might result in PNC: (1) in polymer solution (followed by solvent removal), (2) in a monomer (followed by polymerization), and (...

This paper introduces the most important theoretical and methodological works (monographs, studies, textbooks) that have set course for word-formation research, especially regarding its methodology, in Slovakia since latter half of 20th century, starting with a pioneering monograph by J?n Horeck? entitled Slovotvorn? s?stava slovenciny [Slovak Word-Formation System] (1959), followed other disti...

OBJECTIVE To estimate the cost of preparing cytostatic drugs in the intravenous preparation unit in a hospital in Mexico. METHOD The annual cost of preparing cytostatic drugs based on the information of 92 days, considering the costs of drugs, the mixing service (including standard solution, quality control, services and waste) and salaries were estimated. The costs are estimated in Mexican p...
