Two Problems of Regression Theorem
Authors: Pošvanc Matúš
Published: June 2024

For Mises ([1912], 1953), it is impossible to explain the objective exchange value of money entirely by reference to its monetary utility. He never applied directly the law of diminishing marginal utility to money, even though it is the diction of the theory of subjective value once we explain the price of goods. He claimed that to explain the purchasing power or price of money is possible only indirectly. This is why he developed the Regression Theorem. The Theorem should overcome the problem with the direct application of the law of diminishing marginal utility to money and should explain the essence of the price of money. It will be shown that in doing so, Mises used the objectivist approach per se. The argument will be demonstrated, based on two of Mises´s mistakes: first, on the mixing of the use and exchange value of goods, so the non-proper differentiation of the concepts of marketability and moneyness and second, a core mistake, by using past prices as the base concept for the derivation of new prices, money included.

Authors: Li Jing , Shi Huaqi , Liu Xinning
Published: June 2024

The healthy district evaluation system quantifies the impact of the built environment on residents' health on the spatial elements, providing an effective path for urban renewal to take into account public health. There are few studies on the systematic evaluation of healthy blocks at domestic and foreign, and the mechanism of spatial environment affecting public health is still unclear. Therefore, this paper, by sorting out the built environment evaluation indexes on the block scale proposed by domestic and foreign scholars, and based on policy documents, academic literature and news media materials, determines the weights of each index through the analytic hierarchy process and builds the evaluation index system of healthy blocks. Finally, using Dongba Area in Chaoyang District, Beijing as an empirical case, we explore the mechanism of spatial layout, transportation, public services and living environment in four dimensions of spatial elements on residents' health, and provide planning suggestions for the construction of healthy blocks.
The Impact of Cement on the Mechanical Properties of Expansive Soil
Authors: Jia Wang
Published: June 2024

Expansive soil is a type of clay soil that expands when wet and shrinks when dry, exhibiting extremely unstable properties. This often causes uneven swelling and shrinking deformations in buildings, leading to cracks, tilting, and even destruction. This paper explores the ameliorative effect of cement on expansive soil by conducting direct shear tests under different moisture contents. The tests demonstrate that cementing expansive soil causes a decrease in the particle size distribution, and a noteworthy divergence in the shear stress-shear displacement relationship curves between the two types of soils is observed as the moisture content fluctuates. The cohesion disparity is slight, yet the angle of internal friction alteration with varying moisture content is considerable. Adding cement to expansive soil can significantly enhance the stability of the soil, making engineering projects safer.

Authors: Liu Xiaozhen
Published: June 2024

In practical engineering, the use of double-tower structures with large chassis is becoming increasingly widespread due to their novel shapes and diversified functions. However, the previous earthquake damage shows that complex structures are more prone to damage, and their irregularity aggravates the response to earthquake. In this paper, SAP2000 software is used to establish a model for static elastic-plastic (Pushover) analysis of the large chassis double-tower structure, to investigate the location of the performance points and the distribution of plastic hinges under multiple encounters and rare earthquakes. The results show that under the action of earthquake, when the target displacement is reached, no plastic hinges appear in any of members, which meets the design requirements; the plastic hinge first appears in the beam, and then appears in the column, mainly showing the B state plastic hinges, and the structure has good seismic performance, meeting the seismic design requirements of “strong column and weak beam”.

Authors: Wang Chen , Pan Weiyuan , Yu Tingting
Published: June 2024

Addressing the well leakage issues encountered during drilling in volcanic clastic rock formations, this paper thoroughly analyzes the causes of well wall instability and frequent loss, and explores the possibility of improving plugging efficiency and well wall stability through scientifically formulated plugging materials (lost circulation materials, LCMs). Focusing on the common problems of plugging materials in such complex formations—such as poor adaptability to the leakage layer, inadequate temperature resistance, and insufficient pressure-bearing capacity, the paper introduces a new scientific plugging strategy aimed at increasing the success rate of plugging and improving the replicability of plugging methods. The study employs experimental and numerical simulation methods to optimize and evaluate different formulas of plugging materials for their leakage resistance and borehole wall stabilization in the drilling fluid system. The research results show that a carefully designed combination of rigid and flexible materials can achieve better plugging results in performance tests for fractures of various widths, with formulas one and four performing particularly well. Therefore, choosing the appropriate plugging material formulation plays a significant role in enhancing the success rate of a single plugging attempt and well wall stability, which is crucial for ensuring drilling safety and progress.

Enhanced Long-Term Prediction Based on 2D Tensorization for Building Energy Consumption
Authors: Deng Song
Published: June 2024

Building energy consumption constitutes a significant contributor to greenhouse gas emissions. Precise forecasting of energy consumption in buildings plays a pivotal role in managing building energy efficiently, thereby aiding in the reduction of greenhouse gas emissions. However, existing prediction algorithms often focus on within-period variations in energy consumption data and overlook between-period variations. This limitation makes it challenging to achieve precise prediction results, especially for long-term forecasts. To address this research gap, this paper proposes an Enhanced Long-Term Prediction based on 2D Tensorization (ELP2T) for building energy consumption. First, a Frequency-Guided 2D Tensorization Network (FG-2TN) is proposed. Energy consumption data, when represented as a one-dimensional time series, faces certain limitations, and FG-2TN is employed to address these limitations. Second, a Progress-Optimized Deep Convolutional Network (PO-DCN) is proposed. It is designed to efficiently extract and learn features from the obtained two-dimensional tensors with fewer parameters and less time. Third, a modular method is proposed to transform one-dimensional time series into two-dimensional tensors using Fast Fourier transform. These tensors are processed and then concatenated into a one-dimensional sequence for output. Ultimately, a comparative analysis was carried out using several traditional forecasting algorithms to highlight the superior performance of the ELP2T model. The obtained average R² score for our proposed method is 0.807, representing an impressive enhancement of 11.06% compared to the most advanced alternatives. This substantial improvement firmly establishes the superiority of our approach. Especially, when considering a prediction length of 720 units, the performance gain of this metric increases to 18.09%, underscoring the pronounced advantage of our method in addressing long-term forecasting scenarios.

Published: June 2024

Understanding the effects of climatic factors on maize yield will benefit tactical decisions for future agricultural forecasting. In this study, the relationship between maize yield and meteorological factors has been estimated on the basis of daily meteorological data during the growing season and maize yield observation data from 1970 to 2022 on the island of Nguazidja. The specific maize growth stages most sensitive to meteorological factors were divided into six stages: emergence, jointing, tasseling, flowering, filling and harvesting. First, a simple regression is carried out with the tendency model. Yield and years are included. We then analysed the effect of meteorological factors on each stage of maize growth using the orthogonal Chebyshev polynomial regression. It was found that rainfall has a generally positive influence on yield growth. Temperature has a significant negative effect on yield during the emergence and filling stages. The key point is that meteorological factors have an effect on maize yield throughout the growth season. The degree of impact of each meteorological factor during the growing season is not the same. The first step is to understand that maize needs higher temperatures, especially during the emergence period. On the other hand, rainfall sometimes provides more water than is needed. The aim of this research is to provide clear information on the impact of climatic factors on maize yields. This is a study that has not yet been carried out in the country. And the results are important for forecasting maize yields in the Comoros.

Minqin Basin holds more rate of dependency on water resources and more vulnerability sensitivity to the ecological environment. It is the key to carry out research on the optimization of agricultural planting structure and priority research on water saving, so as to produce the largest economic and ecological benefits for agriculture under the condition of limited water resources. Research and study shall be carried out on the agricultural planting structure of Minqin Basin with examples through the establishment of constraints and objective functions and the construction of a linear programming model based on the high-efficiency water-saving technology of agriculture. The local crop planting structure has changed significantly from 1995 to 2020, which is mainly reflected in: (1) The total planted area of crops rose significantly, from 438,200 to 1000,000 hm2; (2) The planting area of grain crops tends to grow, and the economic crops and other crops tend to fall down; (3) The local net output value rose up significantly, from 4.8 ×109 yuan in 1995 to 5×1010 yuan; (4)The planned crop planting area is slightly larger than the crop planting area in 2020. However, the total output value of crops grows to 3.43×108 yuan, which is 1.18 times the output value in 2020. As there are demands urgent for water saving in agricultural planting in Minqin, it is imperative to optimize planting structure and promote advanced irrigation technology.

For critically ill patients with acute kidney injury (AKI), early warning and intervention can be achieved through monitoring serum sodium levels. However, the normal range of serum sodium levels in AKI patients in the intensive care unit (ICU) is not yet clear. This article aims to use statistical methods to study the relationship between changes in serum sodium and hospital mortality in critically ill children with acute kidney injury. This article conducted a retrospective observational cohort study on multiple critically ill children with acute kidney injury using the China Large Pediatric Intensive Care Database to demonstrate that serum sodium levels as an independent predictor can be used to evaluate the hospital mortality rate of critically ill children with AKI. A total of 1505 eligible critically ill children with acute kidney injury were included in the study. The research results indicate that the normal range of serum sodium in children with AKI is approximately 135 to 142mmol/L. The increase or decrease in serum sodium concentration in critically ill children with acute kidney injury admitted to ICU is associated with in-hospital mortality. Therefore, in the ICU, it is necessary to continuously monitor and evaluate the serum sodium levels of children with acute kidney injury to prevent death due to the progression of the disease.

Class is the basic unit of school management, which is of great significance for the implementation of school management and the physical and mental health development of students. The quality of class management not only affects the academic performance of each student in the class, but also affects the formation of students' personality and character. Since the senior primary school students have a certain understanding of class management, this paper takes the self-management of the upper primary school class as the research topic, and the senior students of Wenchang Primary School as the research object. We deeply investigate and analyze the current situation of class management, and its existing problems. We proposes the participation of all the students, so that the students can be the little masters of the class.

In order to ensure the accuracy and reliability of the test results, the carbon monoxide content in the waste gas of fixed pollution sources was used on the field data. By explaining the steps and principles of the field operation, Establishing a mathematical model for the uncertainty of the carbon monoxide content in the exhaust gas, the main sources of the uncertainty components are analyzed, and the uncertainty assessment of class A and class B is passed. The results show that the main sources of uncertainty components include repetitive measurement, instrument value error and CO standard gas, which are 4.15%, 0.982% and 1.15% respectively; the extended uncertainty is ± 10 (k=2). The results show that under the condition of ensuring the stability of the process emission, increasing the number of field measurement is the key to reduce the uncertainty, which is conducive to improving the quality level of the fixed source waste gas monitoring data.
