Published: February 2025

Abstract
Structural colors based on metasurfaces have very promising applications in areas such as optical image encryption and color printing. Herein, we propose a deep learning-enabled reverse design of polarization-selective structural color based on coding metasurface. In this study, the long short-term memory (LSTM) neural network is presented to enable the forward and inverse mapping between coding metasurface structure and corresponding color. The results show that the method can achieve 98% accuracy for the forward prediction of color and 93% accuracy for the inverse design of the structure. Moreover, a cascaded architecture is adopted to train the inverse neural network model, which can solve the non-uniqueness problem of the polarization-selective color reverse design. This study provides a new path for the application and development of structural colors.

Authors: Zhang Yingyu 
Published: February 2025

Abstract
Aiming at the problems of non-smooth motion and unnatural trajectory in motion path planning of dynamic graphics in visual arts, this paper proposes a path planning algorithm based on multi-stage optimization. Firstly, the initial motion path is fitted and smoothed by using Bezier curves to ensure that the motion trajectory of dynamic graphics has high continuity and naturalness. Next, a multi-objective optimization strategy based on a genetic algorithm is introduced to comprehensively optimize the path smoothness, motion speed change, and visual comfort through the adaptive evaluation function. Finally, a dynamic weight adjustment mechanism is adopted to adapt to the changes in the requirements of different visual scenes in real time. Specifically, the standard deviation of the curvature variation of the path generated by the multi-stage optimization-based path planning algorithm is 0.0459, which is much lower than that of the other two algorithms; the mean squared error (MSE) of the speed change rate is 0.65, which is significantly reduced compared with other methods; in the visual comfort test, the fixation point dwell time is 360 ms, which is significantly higher than other methods. The dynamic deviation is the lowest. Experimental data shows that the algorithm in this paper effectively solves the problem of unsmooth motion trajectories of dynamic graphics, significantly improves the naturalness and visual experience of the path, and proves the practicability and superiority of the algorithm in visual art creation.

Abstract
A photovoltaic system employs solar cell modules and supplementary apparatus to transform solar energy into electrical energy. Its stable operation and security are directly related to people’s livelihood and social development. A variety of authentication schemes have been put forth as potential solutions to the security challenges in the photovoltaic system. However, the majority of these approaches continue to exhibit shortcomings in terms of privacy and/or performance. To enhance the efficiency and security of the photovoltaic systems, we propose a lightweight and efficient scheme for authenticating and agreeing keys‥ In this proposed scheme, we adopted lightweight operations such as cascading, XOR, and hashing to reduce the storage and computational overhead, rendering it more suitable for resource-constrained scenarios. Performance analysis and experiments demonstrate that the scheme exhibits advantages in both one-to-one and one-to-many circumstances, rendering it suitable for the photovoltaic system.

Published: February 2025

Abstract
Non-intrusive load monitoring (NILM) is a technique that does not require access to the interior of the system or to the interior of each electrical appliance. Instead, it only installs monitoring equipment at the entrance of the user bus. In the course of investigating non-intrusive load identification techniques, it is often necessary to collect extensive user load data in order to confirm the applicability of the proposed load identification methods across various situations. This requirement inevitably entails a significant burden of data collection and organization. In order to overcome this challenge, a hybrid approach was proposed that combines the principle of Frequency Invariant Transformation for Periodic Signals (FIT-PS) with Time Series Generative Adversarial Networks (TimeGAN). This method was employed to generate single-loaded waveform and multi-loaded waveforms, in order to meet the test requirements.

Abstract
High-voltage cables play a vital role in urban power transmission. However, cables can become defective during operation due to corrosion, aging, etc., which can lead to power outages, fires, and other accidents. The time-frequency domain reflection method is a cable detection method, but it uses a detection signal that is difficult to calculate the wave speed due to the continuously changing frequency characteristics, which can lead to errors due to wave speed determination. In this paper, a signal transmission model considering the effects of wave speed and attenuation will be established to simulate the process of signal change. The simulations concluded that in 110 kV high voltage cable which has a 150 m fault point, the signal would generate a positioning offset of 1.1758 m due to the wave speed.

Published: February 2025

Abstract
To study the construction efficiency of the drilling mechanism in different sizes and different construction materials, based on the bending moment theory of the drilling mechanism, the kinematics and dynamics of the drilling mechanism of the integrated machine were studied. In this paper, the finite element simulation model of three kinds of drilling mechanisms with spiral blades of different diameters is established, and the maximum stress and maximum torque of different rock masses such as common sandstone, low porosity sandstone, and high porosity sandstone are studied. The results show that the diameter of the helical blade structure of the existing drilling mechanism has a more direct influence on the maximum stress and maximum torque generated by drilling, while the relationship between rock materials and the maximum stress and maximum torque is different. The research results of this paper have important theo-retical and practical significance for exploring the working efficiency of the drilling mechanism of the integrated machine and promoting the intelligence and mechanization of the integrated machine in the construction of the distribution network.

Abstract
Coconut shells (CS) are frequently discarded, causing environmental and economic challenges in coconut-producing regions. This study examines the performance of using 5%, 10%, and 15% coconut shell as a replacement for coarse aggregate in concrete mixtures. The main objectives are to evaluate how various percentages of coconut shell replacement affect compressive strength and water absorption. The coconut shells were crushed into small pieces similar in size to standard aggregates used in concrete. The results show that the optimum compressive strength after 28 days of curing, with a 5% CS replacement, is 20.87 MPa. Additionally, the optimal water absorption rate observed was 4.28%.

Abstract
The extensive use of concrete in construction significantly impacts the environment, primarily due to the extraction of natural sand and the high CO2 emissions associated with its production. To mitigate these effects, sustainable concrete alternatives involve replacing cement with fly ash (FA) and sand with coal bottom ash (CBA). This study aims to evaluate the compressive strength and permeability of concrete mixtures incorporating FA and CBA. Six series of mixtures were designed, including a control series and mixtures with 10% FA and varying CBA substitutions of 10%, 20%, 30%, and 40%. The physical properties of the materials, such as specific gravity and water absorption, were assessed and utilized to formulate six mixture series. The control specimen was targeted to achieve a compressive strength of 60 MPa at 28 days. These mixtures were rigorously tested for water permeability and compressive strength at 7 and 28 days. The compression tests employed 100 x 100 x 100 mm specimens, while water permeability was assessed using 150 x 150 x 150 mm specimens. The results indicated a strong correlation between compressive strength and permeability (R2 > 0.85). The optimal substitution levels were found to be 10% FA and 30% CBA, which enhanced the strength and permeability of concrete, making it suitable for construction applications.
Behaviour of low-strength reinforced concrete beam strengthened with deep embedment system
Authors: Ridwan R , Yuniarto E , Kamaldi A 
Published: February 2025

Abstract
Conventional retrofitting methods such as external bonding and near-surface mounted techniques are not always feasible due to their reliance on the bond between the epoxy and the concrete surface, which can lead to structural failure. In response to this challenge, we suggest adopting a deep embedment (DE) system as a strengthening approach. This study examines the performance of low-strength reinforced concrete (RC) beams strengthened with steel DE bars. Two RC beams - one control and one strengthened - were constructed and tested under a four-point bending load system. The strengthened beam was enhanced with 8 mm steel bars embedded in the concrete beam’s core. The results revealed that the control beam collapsed owing to shear, while the strengthened beam experienced failure in flexural tension, with most cracks occurring in the flexural span. The presence of DE bars caused the failure mode of the control beam to shift from shear to flexural in the strengthened beam. Additionally, the maximum load sustained by the strengthened beam increased by 14% compared to the control beam, and the stiffness of the strengthened beam at the ultimate load was 2.45 times higher than that of the control beam.

Abstract
With progressive urbanisation, construction waste management (CWM) has emerged as a prominent environmental challenge, with extensive documentation of its environmental, societal, and economic consequences. Recent studies highlight the human factor as crucial to the efficiency of CWM strategies. However, integrating this factor into CWM research presents methodological challenges due to the diverse personality factors involved, complicating the comparison and generalisation of results. This research views CWM behaviour as a product of social influences shaping beliefs and values, alongside systemic freedoms or restrictions in an individual’s environment. Focusing on the Serbian student population, the study identifies key drivers of CWM behaviour among future psychologists, hydraulic and environmental engineers, and construction engineers. Three critical factors emerged: CWM Organization, CWM Social Support, and Social Network CWM Implementation. Civil engineering students experienced the most favourable organisational conditions for CWM, reinforced by strong social networks and role models. Both civil engineering and hydraulic and environmental engineering students were part of supportive social networks, reflecting a professional culture that strongly endorses CWM efforts. This study underscores the importance of social and organisational contexts in shaping effective CWM practices among future professionals.

Published: February 2025

Abstract
The construction industry has promoted many efforts and initiatives to ensure optimal energy utilization through sustainable construction practices. The Industrialised Building System (IBS) is a modern construction technique that effectively supports sustainable building practices. Even though IBS is widely adopted, not all IBS building projects have considered future renovation since the beginning. Not to mention, some of the building owners perceive that renovating IBS is challenging as the renovation contractors have limited experience with IBS buildings. Therefore, this research intends to discover the challenges in renovating existing IBS buildings and establish consideration factors for future use. This research adopts a qualitative research approach, conducting in-depth interviews with seven (7) experienced contractors and designers to gain insights into the challenges and best practices related to IBS building renovation. The data analysis reveals key themes such as economic, technical, design, management, safety, material, and aesthetic factors. Based on the findings, it could be inferred that although IBS offers significant potential for improving efficiency, quality, and safety in renovation projects, there are few substantial barriers. The barriers included logistical and financial constraints, Structural Constraints, Leakage & Water Damage, Supply Chain Management, Safety and Materials Concerns, and resistance to change. The findings from this research are expected to contribute to improving building renovation performance, especially for IBS buildings, by addressing the identified challenges and implementing the best practices.

Published: February 2025

Abstract
Concrete is a very common material used in the construction of infrastructure. Concrete has several problems such as cracking. Cracks occur due to fatigue from loading, environmental factors, creep, and shrinkage in concrete. This method is carried out by mixing Bacillus cereus bacteria in the concrete mixture made with as much as 10% of the amount of water used in the concrete mixture. Based on the research of compressive strength and split tensile strength of concrete, the results obtained the compressive strength value and the tensile strength value of concrete with the addition of Bacillus cereus bacteria as much as 10% of the amount of water increased the compressive strength of concrete by 3.6% from the average normal concrete compressive strength value with a value of 21.35 MPa to 22.12 MPa in concrete with the addition of Bacillus cereus bacteria. The split tensile strength of concrete increased by 24% from the average normal concrete split tensile strength value of 0.25 MPa to 0.31 MPa in concrete with the addition of Bacillus cereus bacteria. From the results of SEM testing on concrete added with Bacillus cereus bacteria, it can be seen that the bacterial cells are needle-shaped.

Published: February 2025

Abstract
This study explores the effect of moderate and vigorous physical activities on subjective well-being and physical health, with moderate and vigorous physical activity as intermediate variables. Survey data were collected from 420 individuals across 92 households between August and October 2019 in Malang Greater Area, Indonesia, including socio-demographics, travel characteristics, time use activity diaries, and Health Quality of Life (HQL) assessments. Using Structural Equation Modelling (SEM), the study finds that moderate physical activity is more prevalent among males, young adults (18-25), middle-aged individuals (46-55), middle-income earners, and workers, with positive influences from household dynamics and non-motorized travel modes. At the same time, private vehicle ownership negatively impacts activity levels. Vigorous physical activity is more common among females, young adults, and those aged 23-45, particularly among workers and those engaged in in-home leisure and sports. However, it is negatively associated with the use of multiple private vehicles and public transport. Both moderate and vigorous activities are linked to improved physical health; however, subjective well-being is lower among individuals aged 23-55 and low-income earners, though positively influenced by non-motorized travel and time-use activities. The findings emphasize the importance of fostering socially engaged, physically active lifestyles within sustainable urban environments. This study highlights the intersections of public health, sustainability, and urban planning, supporting strategies that integrate physical activity promotion into broader urban planning and transport policies, ultimately enhancing individual and community well-being and contributing to environmental sustainability goals.

Published: February 2025

Abstract
In the fields of environmental and civil engineering, peat soil is regarded as one of the most troublesome types of soil in the world. Furthermore, the peat soil is a high compressible material. This paper discussed about stabilization of the peat soil using an ordinary portland cement and crushed seashells which are to determine the physical properties of the peat soil such as moisture content, specific gravity, liquid limit and organic content and to analyse engineering properties through unconfined compressive strength and scanning electron microscope. The samples were prepared with various ratio of mixture whereas 40% cement 20% mixed seashell (C40CS20), 30% cement 30% mixed seashell (C30CS30) 50% cement 10% mixed seashell (C50MS10) with curing day 14 and 28 days. From the observation, it was found that C40MS20 achieved the highest unconfined compressive strength compared to C30MS30 and C50MS10 which was 67.79 kN/m2 at 28 curing days. Meanwhile, the untreated peat soil had very low compressive strength which was only 18.29 kN/m2. Therefore, the ordinary portland cement and the mixed seashell was proved to have significant effect in reaching moderate compressive strength in peat soil.

Abstract
Expansive clay is clay having a high potential for swell – shrinkage when soil water content change. A road construction built on expansive soil will be damaged when the water content of soil varies. To determine the level of road damage based on natural compressive strength is required to know some correlation between compressive strength (qu) and water content (w) in the study area. Research aims to determine compressive strength (qu) and water content (w) vales based on Unconfined Compression Test (UCT), so that it can be predicted an optimum moisture content. Percentage of swelling potential of expansive clay sample will be decrease as long as the addition of wetting – drying cycle during the process and water content.

Abstract
Rubber mounts are widely used as a component to prevent structures from vibration damages associated with various sources that making lifespan at stake. Frequent change of rubber mount can be a waste yet the inspection for faulty rubber mount is impractical. Advancement in technology eases structural health monitoring (SHM) through sensors combined with deep learning (DL) approach. This paper aims to investigate application practicality of DL to detect level of cracks in rubber mounts through vibration signals. Neural network models based on Convolutional Neural Network (CNN), Long Short-Term Memory (LSTM) and their combinations were developed. An experimental setup simulating bridge structure with rubber isolators supporting its base was created. Cracks were induced on the rubber mount to simulate failure conditions. 5Hz and 10Hz constant sine waves along with simulated bridge waveform from an actual bridge excitation were employed. Neural networks were applied with Bayesian approach via dropout layer to reduce overfitting and increase reliability. Results show the highest accuracy achieved by hybrid CNN-LSTM with 99.9% while CNN with 89.0% in the standard sine wave and bridge excitation scenario respectively. Overall, the study shown the practicality and capability of neural network as a SHM approach for crack detection of rubber mount.
