Identifying industrial buildings as a spatial resource for sustainable urban regeneration in high-density post-industrial metropolitan in Asia

ABSTRACT Industrial buildings are an important spatial resource and play a crucial role in sustainable urban regeneration of high-density post-industrial metropolitan in Asia with insufficient spatial resources. This paper develops a machine learning method for identifying industrial buildings from satellite aerial images. It extracts vector footprints of buildings from aerial imagery through image segmentation, establishes a feature engineering model comprising 11 distinct indicators, and introduces a Random Forest model to enhance the analysis. By mining the implicit spatial design requirements present in geographical information, this methodology facilitates the classification of industrial buildings from hundreds of thousands of buildings. The results demonstrate that the identification of typical characteristics can discover the scale, distribution, and surrounding built environment of industrial buildings in Shanghai’s Central City, providing valuable data for managing industrial spatial resources from lot to building granularity, implementing a systematical and comprehensive re-planning, and popularizing adaptive reuse strategy, with the goal of leading a shift in policies and paradigms of urban regeneration for improvement of efficiency, balance, and green transformation in high-density post-industrial metropolitan in Asia.

Ecological Translatology in the Translation of Ancient Chinese Poetry: A Case Study of The Departure from Baidicheng in the Morning

The paper explores the translation of Li Bai’s poem The Departure from Baidicheng in the Morning. Applying the Eco-translatology theory, it aims to analyze how different English translations—by Xu Yuanchong, Yang Xianyi and Dai Naidie, and Weng Xianliang—reflect the adaptation of language, culture, and communication in the translation process. Given “Adaptation and Selection” Idea as well as “Three-D” Theory, the paper compares the linguistic, cultural, and communicative strategies employed by these translators. The findings suggest that each translation demonstrates varying degrees of adaptation, with Xu Yuanchong’s version achieving the most balanced ecological transformation. It is also found that Eco-translatology provides valuable insights into enhancing the accuracy and cultural transmission of Chinese poetry in translation.

Risk Analysis of Regional Carbon Imbalance Based on Carbon Budget Pattern and Its Transformation Trend

Carbon budget accounting and identification of carbon imbalance risks contribute to revealing the impact mechanism and extent of human activity on the regional carbon budget. It is of great significance to conduct regional differentiated carbon governance and promote regional collaborative emission reduction. As a result, this study first constructed a research framework for regional carbon imbalance risk assessment based on carbon budget. Then, the carbon budget was calculated at a grid and county scale taking Henan Province as an example, and its spatio-temporal pattern was discussed. Finally, the regional carbon imbalance risk index was constructed to reveal the temporal and spatial evolution characteristics of carbon imbalance risk in Henan Province. The results showed： ① From 2001 to 2020, the carbon emissions in Henan Province increased from 232 million tons to 586 million tons. Spatially, it exhibited a gradually decreasing distribution pattern from the central areas to the periphery of each city. Carbon absorption showed a slight fluctuating increase trend （117 million-153 million） with a distribution feature of "higher in the west, lower in the east； higher in the south, lower in the north." ② The carbon source/sink ratio in Henan Province showed a characteristic of rapid growth followed by a gradual decline, reaching a peak of 5.14 in 2013. The carbon source/sink value in economically developed areas was significantly higher than that in economically underdeveloped areas. The regional differences in carbon balance transformation were evident, showing an overall "imbalance-neutralization-imbalance" trend. ③ During the study period, carbon imbalance risks in Henan Province gradually stabilized, and the number of districts and counties with a carbon imbalance risk index higher than 0.6 was 107 （68.2%） during 2016-2020. The high-risk areas of carbon imbalance mainly expanded from the Zhengzhou metropolitan area to the periphery along major transportation routes. ④ Future efforts should focus on establishing land spatial optimization and differentiated governance strategies, considering varying carbon imbalance risks across regions. This includes enhancing county-level cross-compensation mechanisms based on carbon imbalance risk assessments； mitigating regional carbon imbalances； and advancing regional collaborative emission reductions, carbon sequestration, and carbon neutrality goals.

Novel imbalanced fault diagnosis method based on generative adversarial networks with balancing serial CNN and Transformer (BCTGAN)

In industrial production engineering, machines cannot sustain faults for extended periods, resulting in limited fault data collection. This scarcity of data impedes the advancement of accurate fault diagnosis models, particularly in the context of small-sample, extremely imbalanced fault modeling, which poses a significant and challenging problem. In this paper, we introduce an innovative data augmentation approach for addressing the small-sample imbalanced problem: the balanced conditioning CNN (Convolutional Neural Networks)-Transformer architecture based Generative Adversarial Network (BCTGAN). Firstly, we employ a serial CNN and Transformer architecture as the foundation of the generator. Secondly, we introduce micro-enhancement and SMOTE (Synthetic Minority Oversampling Technique) enhancement of samples to facilitate model training. Micro-enhancement simply augments the sample size, while SMOTE enhancement enhances diversity. Together, these techniques balance the training process by introducing new loss function terms. Finally, outlier samples are mitigated through a designed multi-domain feature screening method. Despite the added time cost and computational complexity, results from three instances demonstrate that the proposed method holds superior diagnostic results with great potential compared to traditional and general GAN-based fault diagnosis methods. Our work provides theoretical and practical insights for modeling the field of small-sample blended disequilibrium fault diagnosis.

Investments in Fixed Capital of the Oil and Gas Region as an Indicator of Its Readiness for the Financial Embargo and Transformation of the Global Energy Balance

The financial embargo has a special impact on the economic systems of oil and gas regions. This is explained by the increased foreign trade turnover of oil and gas regions, as well as the high capital intensity of the oil and gas industry, a long period of return on financial investments, and the high profitability of innovative investments. Thepurposeof the study is to identify various aspects of the problem of investing in fixed assets in oil and gas regions, find ways, forms and methods of investment stimulation of their innovative production development and assess the possibilities of transitioning to new technological structures in the conditions of a financial embargo and the transformation of the global energy balance.Methodsof regression analysis of the structure and dynamics of investment in fixed capital of organizations in the oil and gas regions of the Volga Federal District were used and polynomial trend lines were constructed until 2030.

Theresultof the study was the development and justification of a system of priority factors for creating a favorable investment climate in oil and gas regions to increase their resistance to the conditions of the financial embargo and the economic transformation of the global energy balance.

Dynamic–quadratic balancing: A computational approach to balancing and model reduction for affine nonlinear systems

AbstractIn this paper, we discuss a new approach to balancing (known as dynamic–quadratic balancing) and model reduction for affine nonlinear system. We give a fresh look to balancing in terms of the dynamics of the system, rather than simply a structural property. With this perspective, we also develop a new approach to obtaining the balancing transformation in one step, instead of a three‐step process as proposed in earlier methods. Further, we explore the relationship between quadratic balancing and input–output stability. In addition, we also develop a computational approach for obtaining the balancing transformation by solving a coupled system of PDEs or inequalities (Lyapunov/Hamilton–Jacobi type). After that, model reduction can be carried out in the conventional way using Hankel singular‐value functions or using a new criterion. Finally, we present some examples to clarify the results.

An adaptive controller for power quality control in high speed railway with electric locomotives with asynchronous traction motors

Introduction. Power quality in an electric railway system pertains to the dependability, consistency, and purity of the electrical power provided to different components and systems within the railway infrastructure. Assessing power quality offers considerable opportunities to improve the efficiency of railway systems. Problem. Managing the flow of active and reactive power effectively, decreasing harmonic currents, and addressing the negative sequence component are all critical parts of improving power quality for electrified rail systems. As a result, flexible AC transmission systems are the major means of minimizing or decreasing these difficulties. Purpose. This study describes a half-bridge reactive power railway power conditioner (HB-RPC) with a novel Ynev balancing transformer. HB-RPC is made up of four switching devices and two DC capacitors and the compensator’s stability is determined by the operating voltage of the DC-link. Any variations or imbalances in the DC voltage might cause the compensator to operate in an unstable manner. Novelty. Of a novel balanced transformer with HB-RPC in a high-speed railway system with two scenarios. Methods. The study utilized MATLAB/Simulink software for simulation purposes. The system integrates a fuzzy logic controller (FLC) and a PI controller to optimize DC voltage, ensuring its constancy and balance, with the objective of improving the overall stability of the system. Results. The simulation outcomes illustrate the efficacy of the control approach. Through a comparison of results between scenarios (two and four trains) with the PI-based-HB-RPC and the FLC-based-HB-RPC, the system exhibits enhanced stability for the proposed railway system when employing the FLC-based-HB-RPC, compared to a controller based on PI. Practical value. The proposed configuration elucidates its role in enhancing both the dynamic performance of the system and the power quality of the three-phase rail traction chain.

Balanced transformer: efficient classification of glioblastoma and primary central nervous system lymphoma

Objective. Primary central nervous system lymphoma (PCNSL) and glioblastoma (GBM) are malignant primary brain tumors with different biological characteristics. Great differences exist between the treatment strategies of PCNSL and GBM. Thus, accurately distinguishing between PCNSL and GBM before surgery is very important for guiding neurosurgery. At present, the spinal fluid of patients is commonly extracted to find tumor markers for diagnosis. However, this method not only causes secondary injury to patients, but also easily delays treatment. Although diagnosis using radiology images is non-invasive, the morphological features and texture features of the two in magnetic resonance imaging (MRI) are quite similar, making distinction with human eyes and image diagnosis very difficult. In order to solve the problem of insufficient number of samples and sample imbalance, we used data augmentation and balanced sample sampling methods. Conventional Transformer networks use patch segmentation operations to divide images into small patches, but the lack of communication between patches leads to unbalanced data layers. Approach. To address this problem, we propose a balanced patch embedding approach that extracts high-level semantic information by reducing the feature dimensionality and maintaining the geometric variation invariance of the features. This approach balances the interactions between the information and improves the representativeness of the data. To further address the imbalance problem, the balanced patch partition method is proposed to increase the receptive field by sampling the four corners of the sliding window and introducing a linear encoding component without increasing the computational effort, and designed a new balanced loss function. Main results. Benefiting from the overall balance design, we conducted an experiment using Balanced Transformer and obtained an accuracy of 99.89%, sensitivity of 99.74%, specificity of 99.73% and AUC of 99.19%, which is far higher than the previous results (accuracy of 89.6% ∼ 96.8%, sensitivity of 74.3% ∼ 91.3%, specificity of 88.9% ∼ 96.02% and AUC of 87.8% ∼ 94.9%). Significance. This study can accurately distinguish PCNSL and GBM before surgery. Because GBM is a common type of malignant tumor, the 1% improvement in accuracy has saved many patients and reduced treatment times considerably. Thus, it can provide doctors with a good basis for auxiliary diagnosis.

MAIN ASPECTS OF THE TRANSFORMATION OF WORLD TRADE REGIMES AT THE PRESENT STAGE

The article is devoted to the analysis of key aspects of the transformation of world trade regimes at the current stage, such as digital commerce, regional trade agreements, protectionism, trade exchange of services, global supply chains and protection of innovative technologies for international economic stability. It is proved that the study of modern trends and transformations of the world economy is an actual theoretical and applied task, which involves the systematic consolidation of methods and mechanisms of interdisciplinary research. Important factor in modern conditions of globalization of trade relations is the use of information technologies, they become the determining factors of victory in the competitive struggle, it allows you to break traditional supply chains and move to the future. Implementation of digital technologies contributes to significant improvement of business results and significantly accelerates strategic changes in the development of world trade. It is summarized that until recently globalization processes were characterized as stable, mostly positive. But at the current stage, it became clear that the processes of transformation are linear in nature and largely depend on the geopolitical situation in the world, the cyclical nature of global economic development, the geographical location and structure of the economy of the countries of the world. The transformation of the management trade balance changes the form and content of world trade regimes .Accordingly, predicting the future, we understand that we cannot give even approximate calculations or make a more or less accurate analysis. The economic interdependence of different countries should be a guarantee of financial success, but in recent decades it has increasingly transformed and turned into something unusual in world trade. The main focus is on the discussion of forecasts for the current year 2024 of international organizations such as the World Trade Organization (WTO) and the World Trade Organization (WTO), which play a key role in regulating trade relations at this stage.

Learnable Leakage and Onset-Spiking Self-Attention in SNNs with Local Error Signals.

Spiking neural networks (SNNs) have garnered significant attention due to their computational patterns resembling biological neural networks. However, when it comes to deep SNNs, how to focus on critical information effectively and achieve a balanced feature transformation both temporally and spatially becomes a critical challenge. To address these challenges, our research is centered around two aspects: structure and strategy. Structurally, we optimize the leaky integrate-and-fire (LIF) neuron to enable the leakage coefficient to be learnable, thus making it better suited for contemporary applications. Furthermore, the self-attention mechanism is introduced at the initial time step to ensure improved focus and processing. Strategically, we propose a new normalization method anchored on the learnable leakage coefficient (LLC) and introduce a local loss signal strategy to enhance the SNN's training efficiency and adaptability. The effectiveness and performance of our proposed methods are validated on the MNIST, FashionMNIST, and CIFAR-10 datasets. Experimental results show that our model presents a superior, high-accuracy performance in just eight time steps. In summary, our research provides fresh insights into the structure and strategy of SNNs, paving the way for their efficient and robust application in practical scenarios.

Experimental linear parameter-varying model identification of an elastic kinetic roof structure

Elastic kinetic structures are a recent approach to design transformable lightweight structures. Their transformation is based on elastic bending, exploiting the compliant material behavior of the structural members. This enables transformable structures with a stable transformation process. However, due to their lightweight and flexible design, elastic kinetic structures are highly sensitive to static and dynamic disturbances. Moreover, such transformable structures exhibit a transformation state dependent dynamic behavior, due to geometric nonlinearities. Nevertheless, most of current research focuses on the principles of elastic kinetic transformation than on effective disturbance mitigation. The latter is usually designed based on low-order control-oriented models. This paper describes a system identification methodology, suitable to identify low-order models for the transformation state dependent dynamics of elastic kinetic structures. The system identification is carried out using a local approach in the linear parameter-varying (LPV) framework. For the identification of local linear time-invariant (LTI) models, the system realization using the information matrix (SRIM) method is applied. The collection of local LTI models is internally balanced using a balancing transformation, in order to represent the locally estimated models with respect to a common state–space basis. Via linear interpolation, an LPV system in grid-based representation is derived. This methodology is experimentally validated with data from an active hybrid roof structure prototype.

A Novel Co-phase Traction Power Supply System in Electrified Railway

The electrified railway has power quality problems such as three phases seriously unbalanced, large harmonics, and reactive power. In addition, the neutral section exists at each power supply section, which restricts the development of the high-speed and heavy-haul railway. This paper proposes a novel co-phase traction power supply system (TPSS) based on a YNvd balanced transformer, which can not only solve the above problems but also save one single-phase coupling step-down transformer, thus reducing the cost and space of the whole system. In addition, the voltage level of the converter switching device can be reduced by the rational design of the transformer tap position, which enhances the reliability and feasibility of the system. The compensation principle and control strategy of the co-phase TPSS based on the novel YNvd balanced transformer are analyzed in detail in this paper, and the compensation current detection and integrated power flow controller (IPFC) control methods are given. Simulation and analysis show that the proposed topology structure and control method are correct and feasible.

Essential and substantive features of balanced spatial development of rural areas: national and global aspects

The article examines theoretical and conceptual approaches to understanding the balanced spatial development of rural areas in the context of transformational economic processes in the agricultural sector of Ukraine and global environmental challenges. The purpose of the study is to further form a systematic view of balanced sustainable development of rural areas with an emphasis on the specifics of agrarian natural resource management. The essence of the economic space of rural areas is revealed through the peculiarities of balanced agricultural management, as well as the use of natural resource potential, in particular, land and resource potential. A system of socio-ecological, economic and institutional directions of management of a conceptual nature has been formed in order to intensify the balanced and continuous transformation of the economic space of rural areas. The developed conceptual directions are a prerequisite for ensuring the economisation and ecologisation of the territorial-spatial organisation of the rational use and reproduction of agricultural potential (in particular, land and resource, natural resource). Particular attention is paid to the issues of determining the structural and functional construction of the space of rural areas on the basis of balanced agricultural management. The proposed structuring of the economic space of agriculture by various criteria is a generalised characteristic of the balanced spatial development of rural areas. The characteristics by means of which the economic space of rural areas receives its qualitative definition (capacity, saturation, density, development, connectivity, tension) are given.

A VHF Circularly Polarized Turnstile Antenna with Balun for Meteor Radar

This paper presents a circularly polarized turnstile antenna for a meteor radar system. The antenna employs a pair of turnstile radiators, a 1:2 power divider and a 90° phase shifter. After a series of simulations and optimizations, the maximum circularly polarized gain at 39 MHz is 5.9 dBic with 96° 3 dB beam width. The simulated axial ratio below 3 dB is from −39° to 39° within the band of interest. Then, the proposed antenna is fabricated and applied to a meteor radar system. Two tests are carried out for radiation characteristics demonstration. In the first test, the VSWR of the proposed antenna is below 1.2 at 38.5–39.5 MHz and keeps good agreement with simulation results. However, the meteor azimuth distribution is illogical when the output results are compared with the Australian meteor detection radar (ATRAD) meteor detection. To address the problem, baluns are investigated and introduced for balanced feeding. The 1:1 unbalance–balance transformer has been used to improve the radiation characteristics of the designed antenna. The final test results show that the meteor radar system with the improved antenna achieves better performances in meteor counts and meteor azimuth distribution.
