Ion-Acoustic Higher Order Non-Linear Structures in Quantum Dusty Plasma

Journal of Modern Physics 2013年第11期4卷 1530-1535页

作者： md Manir Hossain Monirul hasan md A saduzzaman md Mahfuzul Haque Department of Electrical and Electronic Engineering Bangladesh University of Business and Technology Dhaka Bangladesh Institute of Natural Science United International University Dhaka Bangladesh

The prominent features of higher order nonlinear ion-acoustic waves involving quantum corrections in an unmagnetized quantum dusty plasma are revisited with the theoretical framework of Hossain et al. [1]. The fluid model is demonstrated here by its constituent inertial ions, Fermi electrons with quantum effect, and immovable dust grain with negative charge. We have used the ideology of Gardner equation. The well-known RPM method is employed to derive the equation. Indeed, the basic features of quantum dust ion-acoustic Gardner solitons (GSs) are pronounced here. GSs are shown to exist for the value of dust to ion ratio around 2/3 which is valid for space plasma [2], and are different from those of K-dV (Korteweg-de Vries) solitons, which do not exist for the value around 2/3. The implications of our results are suitable for cosmological and astrophysical environments.

Dhaka is one of the most densely-populated megacities in the world. Water supply problem is acute in this city, but the quality of drinking water has tremendous importance as potability. This study was aimed at comparing various physicochemical and microbiological parameters which are very much relevant for the drinking water quality of Dhaka city of Bangladesh. A total of 80 samples from 11 collection point of different places were collected over ten months. After that, the samples were examined by a different measuring device for physicochemical parameter testing. Considering physicochemical parameters, all water samples were within the limit for pH. However, 53.75% water had unsatisfactory for chlorine level. Total Dissolve Solid (TDS), hardness, iron, and alkalinity based unsatisfactory were 28.75%, 15.0%, 8.75%, and 3.75% respectively. Five parameters had taken into consideration to measure the microbiological quality. The cultural and biochemical methods showed that 80 water samples have a different range of contamination. The total aerobic count was unsatisfactory for 53.75% samples. Sixty-one samples were found coliform contaminated that is 76.25% of the total samples and 58.75% sample was carried fecal substances. E. coli and Vibrio was unsatisfactory as 61.25% and13.75% respectively. This study revealed that how much safe is supplied water of a municipal water supplier.

Impacts of Dredging on Fluvial Geomorphology in the Jamuna River, Bangladesh

Journal of Geoscience and Environment Protection 2021年第6期9卷 1-20页

Jamuna, a major braided river in Bangladesh, has an enormous hydrological impact on the surrounding areas and streams. Erosion and sedimentation in the Jamuna river cause a large flow fluctuation and floods round the year. Bangladesh Water Development Board has initiated a pilot capital dredging project in the Jamuna river in 2011-2012, aiming to guide the flow to reduce the risk of failure of the city area and right guide bundh of the Jamuna Bridge. This study explores the long-term role of dredging on river morphology us-ing erosion-sedimentation numerical modeling approaches. Primary data were employed in numerical models to estimate the erosion-sedimentation and compared outputs with the real-time cross-sectional variation at selected sections along the reach during 2012-2013. The analysis suggested that the rate of sedimentation is higher (60% to 80%), where the dredging alignment crosses through the existing sandbar/char. Moreover, a cross-section com-parison revealed that the channel near Sirajganj Hardpoint shifted towards the left (east) bank, and the channel within the study area developed very fast along the right (west) bank. However, satellite image analysis revealed that the major bankline shifting occurred from 2000 to 2010 and the channel shifting was observed from 2014 to 2018 along the reach, mostly, after the construction of some river training works. The variation of the channel per-sistence (40% - 100%) selected part of the study area in the channel inci-dence map, indicating the rapid dynamic behavior of the river morphology. This study showed a good agreement of measured data and simplified em-pirical relationships to predict the long-term morphodynamic behavior of the braided Jamuna river.

Long Range Wide Area Network (LoRaWAN) in the Internet ofThings (IoT) domain has been the subject of interest for researchers. Thereis an increasing demand to localize these IoT devices using LoRaWAN dueto the quickly growing number of IoT devices. LoRaWAN is well suited tosupport localization applications in IoTs due to its low power consumptionand long range. Multiple approaches have been proposed to solve the localizationproblem using LoRaWAN. The Expected Signal Power (ESP) basedtrilateration algorithm has the significant potential for localization becauseESP can identify the signal’s energy below the noise floor with no additionalhardware requirements and ease of implementation. This research articleoffers the technical evaluation of the trilateration technique, its efficiency,and its limitations for the localization using LoRa ESP in a large outdoorpopulated campus environment. Additionally, experimental evaluations areconducted to determine the effects of frequency hopping, outlier removal, andincreasing the number of gateways on localization accuracy. Results obtainedfrom the experiment show the importance of calculating the path loss exponentfor every frequency to circumvent the high localization error because ofthe frequency hopping, thus improving the localization performance withoutthe need of using only a single frequency.
