Better forecast of tropical cyclone(TC) can help to reduce risk and enhance management. The TC forecast depends on the scientific understanding of oceanic processes, air-sea interaction and finally, the atmospheric process. The TC Viyaru is taken as an example, which is formed at the end of 11 May 2013 and sustains up to 17 May 2013 during pre-monsoon season. Argo data are used to investigate ocean response processes by comparing pre-and post-conditions of the TC. Eight oceanic parameters including the sea surface temperature(SST), the sea surface salinity(SSS), and the barrier layer thickness(BLT), the 26°C isotherm depth in the ocean(D26), the isothermal layer depth(ILD), the mixed layer depth(MLD), the tropical cyclone heat potential(TCHP) and the effective oceanic layer for cyclogenesis(EOLC) are chosen to evaluate the pre-and post-conditions of the TC along the track of Viyaru. The values of the SST, D26, BLT, TCHP and EOLC in the pre-cyclonic condition are higher than the post-cyclonic condition, while the SSS, ILD and MLD in the post-cyclonic condition are higher than the pre-cyclonic condition of the ocean due to strong cyclonic winds and subsurface upwelling. It is interesting that the strong intensity of the TC reduces less SST and vice versa. The satisfied real time Argo data is not available in the northern Bay of Bengal especially in the coastal region. A weather research and forecasting model is employed to hindcast the track of Viyaru, and the satellite data from the National Center Environmental Prediction are used to assess the hindcast.

A Novel Design of an Aquatic Walking Robot Having Webbed Feet

引用

International Journal of Automation and computing 2017年第5期14卷 576-588页

作者： Saad kashem Hutomo Sufyan Swinburne University of Technology Sarawak CampusJalan Simpang Tiga 93350KuchingSarawakMalaysia

Inspired by the movement of duck that is able to move on land and water utilizing its webbed feet, a novel design of an amphibious robot has been presented in this paper. In contrary, the orthodox design of amphibious robot utilizes the tracks or wheels on land and switches to the propeller to move in water. The proposed design employs same propulsion system as webbed feet to move on land and water. After studying the movement of the duck underwater, a conclusion has been drawn that it is swimming in the water by moving its webbed feet back and forth to generate force to push its body forward. Recreating this phenomenon of duck movement, hybrid robot locomotion has been designed and developed which is able to walk, swim and climb steps using the same propulsion system. Moreover, webbed feet would be able to walk efficiently on muddy, icy or sandy terrain due to uneven distribution of robot weight on the feet. To be able to justify the feasibility of the design, simulations are being carried out using SimulationXpress of the SOLIDWORKS software.

Frontiers in Energy 2016年第4期10卷 466-472页

作者： Huzaifa MUBARAK Saad Bin Abul kashem Sarawak Campus Swinbume University of Technology Kuching93350 Malaysia

The recent trend in light emitting diode or LED lighting applications and their claimed energy saving capabilities together with their overall attractiveness has us all convinced that they really are a greener alternative to the compact fluorescent lights or CFL. As convincing as it seems, the actual energy saving capabilities of LEDs are yet to be proven scientifically or at the least, on an empirical level when compared to CFLs. This paper tackles the issue with the use of a solar cell by evaluating the photovoltaic current and voltage generated by the solar cell subjected to each lighting system. Graphical representations are drawn and a conclusion is then reached based on the amount of power generation in the solar cells in order to determine the energy saving capabilities of each lighting system and its efficiency. From the result, it has been found that an LED is 3.7 times more power efficient than a CFL based light source of equal wattage.

Effects of Organic Manures in Changes of Some Soil Properties at Different Incubation Periods

引用

Open Journal of Soil Science 2014年第3期4卷 81-86页

作者： Sajal Roy Md. Abul kashem Department of Soil Science University of Chittagong Chittagong Bangladesh

A laboratory incubation experiment of 60 days was carried out to observe the changes of soil pH, electrical conductivity (EC), soil organic carbon (SOC), and potassium chloride extractable nitrogen () in a soil to which three animal manures viz. cow dung (CD), chicken manure (CM) and a combination of CD and CM had been applied at a rate of 10 t·ha-1. The effects of manures varied with manure type and incubation period. Soil pH slightly increased with the incubation period up to 30 days there after it declined with time significantly (p < 0.05). There was a significant (p < 0.05) increase in EC as days of incubation increased. Organic carbon contents of manure treated soils reached its peak at 15 days of incubation and decreased thereafter with time. The content of increased significantly (p < 0.05) as incubation period increased in control and cow dung amended soils whereas there was no significant difference in contents when either chicken manure alone or cow dung and chicken manure mixed in combination. After 60 days of incubation, the highest amount of was found in cow dung plus chicken manure treated soil followed by chicken manure treatment.

Extractable Phosphorus Contents of Some Soils of Bangladesh and Their Correlation with Phosphorus Concentration in Rice Leaves

引用

Open Journal of Soil Science 2013年第2期3卷 115-122页

作者： Enamul Haque Abul kashem Khan Towhid Osman Department of Soil Science University of Chittagong Chittagong Bangladesh.

To observe the availability of phosphorus by different extraction methods in some cultivated soils of Hathazari Upazilla of Chittagong District, this study was carried out with 36 surface soil samples (0 - 15 cm) belonging to six soil series, namely Bijipur, Pahartali, mirsarai, Manu, Raojan and Noapara. Physical and chemical characteristics of the soils were also determined with an objective of identifying the soil factor(s) regulating P extractability. Three P extraction methods, namely Olsen (0.5 M NaHCO3, pH 8.5), Mehlich-3 (0.2 N CH3COOH + 0.013 N HNO3 + 0.015 N NH4F + 0.25 N NH4 NO3 + 0.001 M EDTA) and Bray & Kurtz-1 (0.03 N NH4F + 0.025 N HCl) were used. There was a wide variation in the extractability of P ranging from low to high categories. Olsen method extracted the largest amount of P (2.07 - 45.36 mg·kg-1) while Bray & Kurtz-1 extracted the smallest amount (1.02 - 21.79 mg·kg-1). The mean extractable P in soils was found to be in the order of Olsen > Mehlich-3 > Bray & Kurtz-1. Soil pH was the most dominant factor in determining P extractability. Available P was negatively correlated with percentage of clay, organic carbon and CEC and positively correlated with pH. Although the three methods extracted different amounts of P from soil, values of P extracted by the different methods were strongly correlated among themselves and with the leaf phosphorus concentration of rice growing in these soils.

Effect of Organic and Inorganic Amendments on the Phytoavailability of Phosphorus to Corn (<i>Zea mays</i>)

引用

Open Journal of Soil Science 2012年第1期2卷 50-54页

作者： Mejbah Uddin Abul kashem Khan Towhid Osman Department of Soil Science University of Chittagong Chittagong Bangladesh.

A pot experiment was conducted to investigate the effect of cow manure, city waste, chicken manure and TSP on the growth of corn (Zea mays) and phytoavailability of phosphorous (P) in soil. An air dried sandy loam soil was mixed with different amendments at rates equivalent to 0, 200, 400 and 800 mg P kg–1 soil based on total P. The plant height and leaf number increased in the plants grown in amended pots compared to control pot. The dry weight of shoots and roots in the control pot were 14.3 and 2.8 g, respectively. The shoot dry weights of corn increased from 43.8 to 76.6 g with the cow manure, 27.8 to 38.7 g with the city waste, 48.4 to 68.2 g with the chicken manure and 30.2 to 32.2 g with the TSP amendments when the P addition rates increased from 200 to 800 mg P kg–1 soil. Similar effects of these amendments and their rates were also found in the case of roots dry weights production. Phosphorus concentration in the plant parts increased with the P application from different amendments but the increase was higher with the TSP fertilizer and lower with the city waste amendments. Olsen P (measured after the plant harvest) increased with P application rates. The extractability of Olsen P from different amendments increased in this order: city waste < chicken manure < cow manure < TSP. Olsen P was strongly related with both shoot and root P concentration of corn (r = 0.910, p = 0.000), indicate suitability of Olsen P to predict plant available P. These results imply that cow manure and chicken manure could be recommended to use in the agricultural field for producing optimum yield.
