Northeast China has been facing a severe power shortage situation. Since September 2021, “power rationing” events occurring in many places the three provinces of northeast have causing inconvenience to people’s production and life. Therefore, it is particularly important accurately predict load combined with influencing factors local consumption. At same time, region about enter heating season, pressure on coal electricity will further increase. In Heilongjiang Province, due capacity...

Abstract:

In order to deeply study the mechanism of prestressed anchor anti-slide pile, an indoor model experimental device was developed, and a finite difference particle flow numerical analysis slope cable pile established based on reinforcement project in mountain road slope. Based force displacement characteristics influence prestress cable, inclination angle width column spacing landslide, height nature filling soil deformation are discussed, some design parameters optimized. Results show that...

A method of biomimetic visual perception and image reconstruction based on pulse sequence events is proposed, the proposed facilitates a behavioral model vision sensing. Based model, relationship between light condition quality reconstructed videos analyzed. In this sensing method, defined as synchronous sequence. The adopts readout asynchronous pixel level mechanism. Light intensity can be calculated by sequences or video further reconstructed. As photocurrent increases, real-time...

When the pulse-sequence-based image sensor films high-speed moving objects, lag problem may appears as blurring in reconstructed images. In this paper, an algorithm is proposed to suppress lags by distinguishing area and calculating ratio of bright dark part one trigger interval. The bases on sensor's characteristics principle that change light intensity cannot be immediately reflected pulse generated from photoelectric accumulation. effectiveness verified both behavior-level model real...

Accurate estimation of water content in an oil-water mixture is a key technology oil exploration and production. Based on the principles microwave transmission line (MTL), logging probe important measuring apparatus. However, effects mixed fluid flow measurement electromagnetic field parameters are rarely considered. This study presents coupling model for low-speed multiphase high-frequency complex pipeline structure. We derived S -parameter equations stratified oil/water model. The...

Abstract Electric vehicles have been touted for their environmental friendliness, as carbon emissions are significantly reduced during the usage phase compared to traditional petrol vehicles. However, from a lifecycle perspective, it is necessary examine how components of electric obtained, constructed, operated, maintained, and disposed better inform impact on environment. Moreover, environment's focus often but less other forms such ecotoxicity marine life. To study emission reduction...

Large-scale ancient landslides are widely distributed in Southwest China, yet their reactivation mechanisms remain complex and poorly understood. On 25 July 2020, one such landslide Liujing Village, Wulong District, Chongqing, experienced reactivation. This event exhibited variable movement characteristics across different areas times, ultimately manifesting as a chain-type failure. Combining field investigations drilling works, this study describes the fundamental of Zhongbao variation...

A core mission of university education is to train students' problem solving abilities, or in some cases, research skills. To achieve this, educators assign students certain experiment courses, where complete a task following preset procedures. However, such courses often employ outdated teaching materials that are far from cutting-edge problems. Meanwhile, procedure cannot evoke innovations. In this article we introduce an experimental course opened at Shanghai Jiao Tong University for...

PP-wave and PS-wave event registration is an essential element in multicomponent data analysis. In seismic exploration, multi-wave usually shows big difference quality, which makes it difficult to obtain stable Vp/Vs ratios, leads inaccuracy between image volumes. this paper, we developed a practical approach for volumes based on the 3D non-rigid matching algorithm. First, with relatively accurate model of ratios derived from prior information such as VSP, rough PP time scale can be...

In this paper, taking MM6 metallographic microscope 160 × as an example, one kind of new method is studied on measuring actual total magnification by digital images, the image virtual viewed through eyepiece and acquired camera instead eyes. Results show: 1) The images 5/100 ocular micrometer 1/100 stage in eyepieces are acquired. 5 grade gauge block, which 5mm length from 250 mm, same acquiring conditions. lengths block measured, then calculated. objectives tube factor product factor; 2)...

Abstract The research method of LF-NMR(low field nuclear magnetic resonance) combined with core displacement device has become important experiment was used to study the Water Flooding SCT(swept control technology by water flooding) soft microgel. Besides, transverse relaxation time spectrum and “visual” evaluation based on LF-NMR were investigate microscopic mechanism expended sweep volume microgel in single experiment. conformance effect flexible parallel double-core its at different pore...

Tuberculosis remains a persistent global health threat and leading cause of mortality. Drug therapy currently serves as the primary approach for tuberculosis treatment. However, drug-resistant cases have emerged among patients. Accurately identifying drug resistance in patients is paramount effective A practical artificial intel-ligence algorithm relies heavily on substantial volume meticulously labeled data. Unfortunately, there scarcity analysis clinical settings. To address challenge...
