Assessing the variation of the dry season’s surface temperature in Binh Duong province from 2002 to 2016 by applying thermal remote sensingThe study was conducted to evaluate LST variation in the dry season of Binh Duong province between 2002 and 2016. The LST values are calculated from the grayscale value of Landsat 7 ETM+ and Landsat 8 OLI/TIRS infrared images. The average temperature of the dry season after 15 years has decreased by about 1.5 oC from 30.8 C in 2002 to 29.3 C in ...

Aerosol ph in Ho Chi Minh city, Viet NamIn this study, we firstly report the aerosol pH in PM2.5 based on the data which was collected at the HCMC site by using the filter pack method. The aerosol pH is a parameter of interest for the atmospheric implication of aerosols but is difficult to measure directly. To calculate the aerosol pH we apply two approaches including the thermodynami...

Green growth prediction of Ho Chi Minh city by the grey theory modelThe green growth index of 13 districts in HCMC consists of 9 subjects and 18 indicators. The green growth index is a useful tool for assessing and monitoring the current state of socioeconomic development. The green growth index was built based on the weight of the principal component analysis for the objective evaluation results. The grey predic...

Phương pháp tính toán dự đoán vùng thấm nguy hiểm trên mái đập đất chịu ảnh hưởng của thủy triềuAmplitude of osillation of water table surface and hydraulic gradient under tidal effect, tend to decrease while the seepage flow enters the earthen dam. Therefore, there exists a Dangerous Seepage Triangular Area (DSTA) where hydraulic gradient obtains maximum values. Based on the continuity equation and an assumption on the transmission of see...

Đánh giá hiệu quả của hệ cản ma sát biến thiên với công trình chịu tải trọng động đấtThe implementation of variable friction dampers (VFD) for vibration mitigation of seismic structures generally requires an efficient semi-active control method. In this paper, a semi-active model control method is proposed to determine the controllable clamping force of a variable friction damper. A comparative study was performed on a multiple...
