Abstract It is important for civil engineering applications to investigate resistance wood decay in aqueous environments. DNA from microorganisms inhabiting logs (groynes) that had been used about 15 years as a water control system prevent riverbank erosion was extracted and the microbial community structure examined. specimens four sections, above under water, ground bottom parts of were pulle...

The purpose of this research was to develop a model for counting or classifying annual tree rings lamphu trees along riverbanks. study based on image processing combined with deep learning and machine the model. data augmentations were processed through preprocessing region interest, denoising, color conversion, blurring, thresholding, dilation. This process transforms one image’s into seventy ...

This paper is presented a system that monitor the river water level by using computer vision with image processing and IoT. developed to detect riverbank applying where edge detection technique applied on both images captured video camera. The flood severity determined comparing level. Then, upload IoT platform. A notification sent people when reached certain critical via Telegram app which one...

BACKGROUND Species movement responses to landscape structures have been studied using a variety of methods, but movement research is still in need of simple methods that help predicting and comparing movements across structurally different landscapes. We demonstrate how habitat-specific movement models can be used to disentangle causes of differentiated movement patterns in structurally differe...

1,1-diacetates(acylals) were prepared by direct condensation of various aldehydes with acetic anhydride using dipyridine cobalt chloride (copy2cl2) as an efficient and green catalyst under solvent-free conditions at room temperature. the important features of this catalyst method are that the catalyst is solid, stable at high temperatures, soluble in water, stable in air, immiscible in common o...

To facilitate understanding and calculation, hydrogeologists have introduced the influence radius. This parameter is now widely used, not only in theoretical calculation reasoning of well flow mechanics, but also guiding production practice, it has become an essential hydrogeology. However, reasonableness this always been disputed. paper discusses nature radius problems its practical applicatio...

Alluvial rivers all over the world have one common problem, which is their meandering pattern. This meander formation because of natural and anthropogenic processes. Barak River dynamic, due to this, it exposed regular shifting creates many problems for people who reside near river. The livelihood depends on agriculture, they conduct nearby sides However, riverbanks makes life miserable leads s...
