Published: October 2019

Abstract
To determine the effect of partition different types of fertilizer (Acadian, Humus and Foliater) on some vegetative traits and seed yield of sorghum var. Inkath. Field experiment was carried out during spring and autumn 2017 in the experimental fields of crop science / college of agricultural engineering sciences, factorial experiment was applied according to RCBD design with three replications. The three types of fertilizers was the first factor and control treatment. The second factor was the partition of the spray into three ways (whole concentration for one spray, half concentration for two sprays and one third concentration for three sprays ) at seed initiation stage, beside control treatment (spray with distil water only). The results of the statistical analysis showed that there was a significant effect of the three fertilizers in the studied traits. The plants treated with Acadian gave the highest average leaf area, chlorophyll content, seed per head, grain weight, and plant yield when compared other treatments. The results also showed partition spray to three sprays was superior to other fertilizer treatments in most studied traits. The results indicates that spray with Acadian into three sprays was best treatment in this study.

Abstract
A laboratory experiment was carried out and repeated at field of College of Agricultural Engineering Sciences, University of Baghdad in 2017. First factor was three cultivars of lupine ‘Giza-1’, ‘Giza-2’ and ‘Hamburg’. Second factor was three seed weights (lower weight, medium weight and higher weight) which was following the cultivars factor. Nested design was used. Results showed supremacy of ‘Giza-1’ cultivar significantly and gave higher germination ratio, radical length, seedling dry weight, seedling vigour index, field emergence ratio, plant height and number of leaves per plant. The treatment (‘Giza-1’×higher seed weight) was supremacy significantly and gave higher germination ratio, radical length, plumule length, and seedling vigour index, while the treatment (‘Giza-1’×lower seed weight) was supremacy significantly and gave higher seedling dry weight, field emergence ratio and number of leaves per plant. It can be concluded that the studied cultivars have potential energy related to the nature of their genotype, which makes them different in their behavior under laboratory and field conditions. The interaction between cultivar and seed weight has a role at the variance of this behavior under a wide range of environmental conditions. Therefore, it can be recommended to cultivate seeds with a lower weight of Giza-1.

Published: October 2019

Abstract
Energy utilization efficiency (EUE) for Movable boards ditch opener (MB) and for conventional ditch opener (CD) were compared using three operating depths for MB(30, 40 and 50cm), three angles between its movable boards, three foot wings widths and two soil types (cultivated an uncultivated soils). For CD there was one angle between its boards (65°), they were permanently fastened, one share width (35cm), one operating depth in the uncultivated soil only (25cm), could not penetrate such soil, and three operating depths in the cultivated soil.The results showed that EUE for MB increased as the operating depth increased in the cultivated and uncultivated soil whereas, for CD it increased in the cultivated soil only whereas, it could not penetrate the uncultivated soil more than 25 cm. However, the rate of increase was almost the same for both implements in the cultivated soil, EUE for CD increased from 5.57 to 7.93m3MJ−1 (2.36m3MJ−1) whereas, for MB, it increased from 9.64 to 11.78m3MJ−1 (2.14m3MJ−1). EUE for MB also increased with angle between its boards and the width of the wings of its foot while for CD did not occurred because it boards were permanently fastened to the machine frame at angle of 65° and it was provided with share rather than wings. EUE for MB was higher in the cultivated soil comparing with uncultivated soil.EUE for MB was higher than that for CD for all operating depths, angle between the boards and the width of the wings of the foot and in both soil types. The results showed that MB surpassed CD in field performance in addition to that it can penetrate the soil to the required depth whether it was cultivated or uncultivated soil. It also can produced different cross-section width ditches whereas, CD can produce one cross-section width ditches.

Published: October 2019

Abstract
Due to various disturbing factors affecting data reception, telemetry information often contains outliers and lost entries. Detection of outliers and anomalies is one of the key problems of satellite data analysis. A comparison of several statistical methods of outlier detection in telemetric information on the power supply system, obtained from the “AIST” small satellites, was carried out for the purpose of increasing the accuracy of satellite’s systems monitoring based on the telemetry data. The structure of telemetry from the power supply and thermal control systems of the “AIST” small satellites was analyzed. Several statistical methods for outlier detection were studied. Methods, described in the paper, allow to detect fast acting changes in telemetry data from “AIST” small satellites.

On the using M-BCJR demodulation for partial response signalling followed by decoding of LDPC codes
Authors: Nguyen T H P 
Published: October 2019

Abstract
This paper studies various sub-optimal versions of BCJR demodulator to examine the possibility of computational reduction. BCJR demodulator is used to deal with intentional intersymbol interference in bandwidth efficient systems. The complexity of BCJR demodulator can be reduced by using the approximation in the logarithm domain and by considering less number of trellis states instead of full states. To estimate the performance of different types of BCJR demodulator, we proposed the partial response signalling system with finite shaping pulse providing 10% gain of bandwidth efficiency. The simulation results of this study show that in the case without error correction coding the complexity of BCJR demodulator can be significantly decreased without energy losses. When low-density parity-check coding is used, it is possible to use these sub-optimal versions of BCJR demodulator, but the system may suffer additional energy losses.

Abstract
Microalgae oil can replace the role of fish and other vegetable oils. One of them is lipid in microalgae Chlorella vulgaris. This study aims to determine the composition of fatty acids in marine microalgae Chlorella vulgaris grown in fertilizer medium. Cultivation was carried out at room temperature, photoperiode 12:12 (dark: light); light intensity 10.000 lux and aerated for 24 hour. The optimum medium used was medium GMF fertilizer with concentration 10% (w/v). Lipid extraction used Blight-Dryer method with methanol, chloroform and aquadest as solvent. The lipid obtained was esterified by NaOH in methanol and H2SO4 as a catalyst for 12 hours and analyzed used GC-FID with capric acid as a standard. The analysis result shows that was 18 fatty acid methyl ester compounds. The highest known fatty acid methyl esters compositions was 61.52% methyl stearate; 15.52% methyl palmitate; 4,69% methyl eicosanoate and 3.34% methyl heptadecanoate from total fatty acids. The unsaturated fatty acids identified were 0.17%. EPA (eicosapentaenoic acid) also 0.23% omega 3 and omega 6. Microalgae grown in a fertilizer medium produce quite high lipids. Although the levels of unsaturated fatty acids are still low, it does not rule out the possibility of being increased.

Published: October 2019

Abstract
In this paper, we report our investigation effect of concentration of silver nanowires (AgNWs) solution on the AgNWs thin films coated onto a glass substrate by simple Meyer-rod coating. Diameter and length of AgNWs have used about 120 nm and 20 to 30 µm, respectively. Concentration of AgNWs were variated of 186 mg/ml, 210 mg/ml, and 223 mg/ml in ethanol solution. AgNWs thin films then were heated at temperature 90 °C for 20 min. The UV-vis spectrophotometry, scanning electron microscope (SEM), and four-point-probe were employed to characterize the AgNWs thin films. The result shows that concentration of AgNWs solution affects on the transmittance and a sheet resistance of the AgNWs thin films. The transmittance at the wavelength of 550 nm is obtained 94.5% by a sheet resistance about 1.2 Ω/sq. The higher concentration of AgNWs solution can decrease the sheet resistance and the transparency of the AgNWs thin films.
