Dimensionality Reduction and Pattern Recognition of Flow Regime Using Acoustic Data

In this study we investigated the novel application of Principal Component Analysis (PCA) in order to reduce the dimensionality of acoustic data. The acoustic data are recorded by fibre optic distributed acoustic sensors which are attached along a 3500 m pipe with a sampling frequency of 10 kHz and for a duration of 24 hours. Data collected from distributed acoustic sensors are very large and we need to identify the part that contains the most informative signals. The algorithm is applied to water, oil and gas datasets. We aimed to form a smaller dataset which preserves the pattern of the original dataset which is more efficient for further analysis. The result of this study will lead to automation of multiphase flow pattern recognition for oil and gas industry applications

Evaluation of Effect of Organic Fertilizer’s Treatments and Soil Compaction on the Qualitative Traits of Sport Lawn in Different Seasons

Natural structure of lawn brings about the sensitivity of it to climate conditions and imposed destructive forces during its use. In this study, the effect of several types of organic fertilizers including leaf mold (LM), rice husk (RH), livestock manure, spent mushroom compost (SMC), a mixture of LM, RH and livestock manure (mixture 1), a mixture of LM, RH and SMC (mixture 2) with the ratio of 1:1:1 and control (no fertilizer) along with several levels of compaction including roller weighted of 36, 56 and 76 kilograms were studied on the change qualitative traits of sport lawn in different seasons. An experiment was conducted at the strip plot design in three replications, in research farm of Gorgan University of Agricultural Sciences and Natural Resources during 2008-2009. According to the results, the chlorophyll rate in the fall was higher than winter and spring. With the comparison of the cover rate, density and height, it was observed that in different seasons, the highest and lowest rate of these attributes was related to spring and summer respectively

The Effect of Fertilizer Treatments at Three Compactness Levels on Qualitative Traits of Sport Lawn in Winter Season

Lawn quality, which introduces by good color, density, uniformity and texture varies depending on the species, maintenance operation, and time of the year. In the current study, the effect of organic fertilizers containing Leaf Mold (LM), Rice Husk (RH), manure, Spent Mushroom Compost (SMC), a mixture of LM, RH and SMC (mixture 1), a mixture of LM, RH and manure (mixture 2), with the ratio of 1:1:1 and control (no fertilizer) at three levels of soil compactness including roller weights of 36, 56, 76 kilograms on qualitative traits of sport lawn were investigated in winter season. Treatments were applied in a strip plot design with three replications, in research farm of Gorgan University of Agricultural Sciences and Natural Resources during fall 2008-2009. According to achieved results, manure and RH treatments in first and second compaction and manure treatment in third compaction level showed the highest amount of chlorophyll content. In visual assessment, the highest and lowest of lawn quality was observed in the manure and the control treatment respectively. In first and second compaction, the maximum height was observed in manure treatment. Control and LM treatments showed the minimum height. In third compaction, maximum and minimum heights were associated with manure and control treatment respectively

Effect of Several Organic Fertilizers Along with Some Soil Compactness Levels on Nutrients Content of Sport Lawn in Fall Season

The lawn has an incredible role in designing and construction of landscape areas and lawn bed provides aeration, moisture and nutrients, which is essential for having an acceptance lawn, so the role of organic matter and degree of soil compactness need to be studied. In the current study, the effect of some bed mixtures including Leaf Mold (LM), Rice Husk (RH), manure, Spent Mushroom Compost (SMC), a mixture of LM, RH and SMC (mixture 1), a mixture of LM, RH and manure (mixture 2) with the ratio of 1:1:1 and control (no fertilizer), also the effect of some different soil compactness (roller weights of 36, 56 and 76 kilograms) on the content of some nutrients of sport lawn in fall season were investigated. Hence, an experiment was conducted at the strip plot design with three replications, in research farm of Gorgan University of Agricultural Sciences and Natural Resources during 2008-09. According to the results of this study, interaction of fertilizer and soil compactness was significant for most measured factors. The manure and control treatments showed the most and the least amount of nitrogen in all compactness treatments respectively. The manure and SMC treatments and also treatments containing these organic matters increased plant phosphorus content in comparing with RH, LM and control treatments. Also in three compactness, manure and SMC treatments showed more plant potassium in contrast to control

The Effect of Different Organic Fertilizers in Various Compactness Levels on the Amount of Some Nutrients of Sport Lawn in spring

Lawn has an incredible role in designing and construction of landscape areas and lawn bed provides aeration, moisture and nutrients, which is essential for having an acceptance lawn, so the role of organic matter and degree of soil compactness need to be studied. In the current study, the effect of some bed mixtures including Leaf Mold (LM), Rice Husk (RH), manure, Spent Mushroom Compost (SMC), a mixture of LM, RH and SMC (mixture 1), a mixture of LM, RH and manure (mixture 2), with the ratio of 1:1:1 and control (no fertilizer), also the effect of some different soil compactness (roller weights of 36, 56 and 76 kilograms) on the content of some nutrients of sport lawn in spring season were investigated. Hence, an experiment was conducted as the strip plot design in three replications, in research farm of Gorgan University of Agricultural Sciences and Natural Resources during 2008-09. According to the results of this study, interaction of fertilizer and soil compactness was significant for most measured factors so that treatments containing manure showed the most nitrogen content in all three compactness levels. As well, in all three compactness levels, the high phosphorus content of plant was also found in manure treatment and the lowest in control and LM. Furthermore, manure, SMC, and treatments containing these two organic fertilizers showed increased potassium of plant toward control and LM
