    Normally most of crude oils contain wax either in small or large percentage. Wax content in crude oils significantly gives some more cost to the production line, transportation and also process plant. So that it play an important role to the operating cost to any sections of oil industry. Wax deposition usually starts when the crude oils are flowing through pipeline or riser. At sea bed and undersea there are low temperature over there which cause wax component in crude oil start to crystallize and precipitate. It also has high viscosity which can cause pumping problems to pipelines. Over certain period of time wax can cause blockage to the pipeline. This kind of problem potentially increase cost of operation and become severe when the operation is being shut down because of pipeline failure. There is a method to overcome this problem by using circulation of hot oil from platform to well. It purposes is to maintain high temperature of flowing crude oil to storage tank, so there are less percentage of wax deposited on the wall surface of tubing. In UTP, most studies on waxes were conducted using batch system. This study will concentrate on continuous system where coolant is circulated in a cold finger flowing through fix amount of hydrocarbon solution. So there is an interest on how is it the deposition process works. Because the way of deposition occurs is different compared to batch system, the pattern and trend of wax deposition is still a question. This research will start by having literature review and number of sets of experiment to collect data and make analysis of wax deposition in a loop. This preliminary report includes project background, problem statement, objective, project scope and limitation, literature review, methodology and references

    The objective of this paper is to determine the relationships of Japan exchange rate volatility with the volatility of Malaysia's macroeconomic variables, namely trade and FDI. The paper presents empirical evidence that shows the relationship of Japan exchange rate volatility on Malaysia trade and Foreign Direct Investment (FDI) volatility. The independent variable is Japan exchange rate (Japanese yen to ringgit Malaysia) volatility and the dependent variable is Malaysia Trade (import and export with Japan) and FDI from Japan. The data collected are quarterly data between 1997 and 2007 and analyzed using Granger Causality Test. The volatility of the variables is measured using standard deviation of growth. After the data has been tested for stationary, the data then are tested in the Granger causality test. The test uses lag 1,2,4,8 and 12. According to the result of the test, there is no evidence of Granger-causes between Japan exchange rate and export to Japan in all lag chosen. For exchange rate volatility and. import to Japan volatility there is a unidirectional causality in lag 1 and bilateral causality in lag 8 and for Japan exchange rate volatility and FDI from Japan volatility, there is a unidirectional causality in lag 4 and 12 where FDI from Japan volatility Granger-causes exchange rate volatility

    Discovering Lexical Similarity Using Articulatory Feature-Based Phonetic Edit Distance

    Lexical Similarity (LS) between two languages uncovers many interesting linguistic insights such as phylogenetic relationship, mutual intelligibility, common etymology, and loan words. There are various methods through which LS is evaluated. This paper presents a method of Phonetic Edit Distance (PED) that uses a soft comparison of letters using the articulatory features associated with their International Phonetic Alphabet (IPA) transcription. In particular, the comparison between the articulatory features of two letters taken from words belonging to different languages is used to compute the cost of replacement in the inner loop of edit distance computation. As an example, PED gives edit distance of 0.82 between German word ‘vater’ ([fa:tər]) and Persian word ‘ ’ ([pedær]), meaning ‘father,’ and, similarly, PED of 0.93 between Hebrew word ‘ ’ ([ʃəɭam]) and Arabic word ‘ ’ ([səɭa:m], meaning ‘peace,’ whereas classical edit distances would be 4 and 2, respectively. We report the results of systematic experiments conducted on six languages: Arabic, Hindi, Marathi, Persian, Sanskrit, and Urdu. Universal Dependencies (UD) corpora were used to restrict the comparison to lists of words belonging to the same part of speech. The LS based on the average PED between pair of words was then computed for each pair of languages, unveiling similarities otherwise masked by the adoption of different alphabets, grammars, and pronunciations rules
