Three typical opening configurations-lane reduction, lane expansion, and lane conservation-are evaluated under low, medium, and high saturation levels with opening lengths of 100 m, 200 m, and 300 m. Four performance indicators-delay, conflict rate, speed difference, and fuel consumption-are extracted from simulation monitoring. Cross-validation revealed that in the lane conservation scenario, all four modules unanimously recommended 100 m across all saturation levels; in the lane reduction scenario, optimal lengths varied by saturation, i.e., 100 m was recommended under low and high saturation, while 300 m was preferred under medium saturation; in the lane expansion scenario, all four modules consistently recommended 100 m under medium saturation, whereas recommendations diverged under low and high saturation; at low saturation, 100 m received the greatest support (2 of 4 modules) without a majority consensus, while at high saturation, 100 m was supported by three of the four modules. The parallel multi-module architecture effectively mitigates single-model bias by enabling cross-validation from complementary theoretical perspectives. The proposed framework provides a robust, data-driven decision-support tool for temporary traffic organization design in expressway reconstruction and expansion.</p>","PeriodicalId":100109,"journal":{"name":"Applied Research","volume":"5 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/appl.70225","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149205908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accidents often occur when the lorry moves the train on the track, especially on bends in the rail, which causes the lorry to move incorrectly following the rail track even though it is controlled by the operator. With this research, based on the Z-cam E2-M4 camera running using NVIDIA Jetson Xavier NX, which is a high-performance module for processing, this device will automatically identify the rail through image processing with the optical flow method, which is believed to be able to overcome track errors in real-time. This image-based technique is not just a simple technique but can function to recognize the railway mapping track by combining edge detection that transforms to isolate certain tracks based on the image sequence, thus keeping the lorry on track. From experiments conducted with a prototype scale on the installation of the train, the results showed an average success rate of 91.16% during the initial testing phase. A total of 10 tests were conducted using the same experimental parameters to evaluate the consistency of the proposed system. For clarity, the results of these 10 tests are represented in Section 4 by three representative track scenarios: straight track under low illumination, curved track, and straight track under high illumination, corresponding to different observation time windows of 00:07, 00:35, and 00:15, respectively. Across the subsequent evaluation of the 10 tests, the peak performance reached 96.7%. These figures are promising for a prototype at scale, although further field testing is needed to ensure the unit's survivability in real-world conditions, even in unpredictable weather conditions like those in Indonesia. This practical implementation is a first step toward addressing accident-related issues using optical flow methods, which are particularly useful in these situations.</p>","PeriodicalId":100109,"journal":{"name":"Applied Research","volume":"5 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/appl.70215","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149205390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The FAHP results indicate that System Failure is the highest-ranked main risk factor (weight 0.343), followed by Human Factor (0.275).

There are still challenges on market demand, infrastructure readiness, operational efficiency, and institutional coordination for implementation of Ro-Ro services within the region. In this study, a combination of Delphi and TOPSIS-based multi-criteria decision making approach is used to estimate the feasibility of some of Ro-Ro SSS routes in the IMT-GT region. The Delphi assessment initially involved 34 experts from Malaysia, Indonesia and Thailand representing academia, the maritime industry, port authorities and government agencies. Thirty experts completed the second Delphi round and constituted the final active panel used to validate the 19 evaluation determinants. The validated determinants were then applied in the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method to rank the four Ro-Ro routes. The TOPSIS results ranked Belawan–Port Klang first, followed by Belawan–Penang, Dumai–Malacca and Belawan–Phuket. Sensitivity analysis also showed the reliability of the ranking results within varying policy scenarios. The results indicate the impact of infrastructure preparedness, financial aid and institutional cooperation as key factors influencing the viability of the regional Ro-Ro services. The study adds to the ongoing discussion on maritime transport by presenting the evidence-based decision-support framework for assessing maritime corridors in the region and provides valuable insights for policymakers and industry stakeholders taking action to ensure maritime connectivity in the IMT-GT region.</p>","PeriodicalId":100109,"journal":{"name":"Applied Research","volume":"5 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/appl.70219","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149145895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although phase change materials (PCMs) and nano-enhanced PCMs (NePCMs) have been widely explored for passive thermal regulation in roofs, the reported findings remain fragmented, with inconsistent performance due to variations in material properties, encapsulation techniques, roof configurations, and climatic conditions. This lack of a consolidated understanding limits their reliable implementation in energy-efficient building design. To address this gap, this study presents a systematic review and critical synthesis of PCM- and NePCM-integrated roof systems, integrating insights from experimental, numerical, and analytical investigations. The review specifically evaluates the influence of thermophysical properties, encapsulation strategies, geometric design of roof elements, and environmental conditions on thermal and energy performance. In addition, hybrid configurations combining PCMs with auxiliary cooling strategies such as night ventilation, reflective coatings, and radiative cooling layers are comparatively assessed to identify performance enhancement pathways. The findings indicate that while PCM-integrated roofs consistently reduce peak indoor temperatures and dampen thermal fluctuations, their effectiveness is strongly governed by conductivity limitations and melting/solidification dynamics. Macroencapsulation remains the most widely adopted approach due to structural feasibility, though heat transfer limitations persist. NePCM systems demonstrate improved thermal response and faster energy exchange; however, trade-offs in reduced latent heat storage capacity, long-term stability, and cost are evident. Overall, hybrid and multilayered roof systems exhibit the greatest potential to enhance passive cooling.</p>","PeriodicalId":100109,"journal":{"name":"Applied Research","volume":"5 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/appl.70213","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149205426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although research in this area is rapidly expanding, each of the models developed so far still presents limitations in scalability and transferability to various building environments attributed to the differences in modelling strategies, data inputs, sensing approaches and evaluation methods. The current review studies have tended to be limited to a specific aspect of occupancy modelling (algorithm, sensing technology or control strategy) and a more comprehensive synthesis is needed that incorporates these in the broader context of energy-efficient building operations. This review aims to critically discuss recent approaches for modelling occupancy behaviour and predicting energy consumption using ML techniques and identifies their modelling approaches, modes of sensors, context of applications and methods of evaluation. Over 80 peer-reviewed studies were critically reviewed to formulate a structured synthesis of existing modelling approaches, compare their applications across different building types and identify methodological advancements and remaining challenges that hinder practical deployment. The results of the analysis suggest a strong trend towards non-intrusive sensing, hybrid and context-aware modelling, explainable and privacy-preserving artificial intelligence and the growing use of sensor fusion to enhance the reliability of the predictions. Meanwhile, there is a lack of model transferability, benchmarking inconsistencies, data heterogeneity and a lack of standard datasets, which hinders broader deployment. This review succinctly summarizes existing research and points out future research directions that will enable the construction of scalable, transferable and ethically responsible occupancy-aware energy management systems and can serve as a handy resource for researchers, engineers and policymakers.

Unlike conventional mixed-filler formulations, this work employs a staged evaluation framework in which GS and IS composites were first tested individually and subsequently combined as two separate layers. The measured results show that both GS and IS composites exhibit absorption-dominant shielding behavior and that selected paired configurations provide improved shielding compared to several single composites. The improved shielding response is attributed to the combined effects of conductive network formation, dielectric relaxation, interfacial polarization, and multiple internal reflections within the stacked structure. The GS40–IS40 configuration showed a maximum (SE<sub>T</sub>) of approximately 62 dB at 11.2 GHz within the WR-90 X-band range of 8.2–12.4 GHz.

Traditionally, strong acids and bases are used to remove proteins, minerals, and acetyl groups, but this can harm the polymer and create hazardous waste. This review examines chemical, biological, physical, and combined extraction methods that aim to reduce or avoid steps that generate chemical waste while maintaining high product quality. Chemical extraction usually gives a degree of deacetylation (DD) between 25.25% and 99.5% and a molecular weight (MW) between 22.7 and 865.7 kDa. Hybrid methods yield DD values between 55.3% and 97.7% and MW values between 53.4 kDa and 500 kDa. Hybrid chemical-biological methods, such as those using enzymes or fermentation, lower the need for chemicals to turn chitin into chitosan. Hybrid chemical-physical methods, such as microwave or ultrasound, help move materials more quickly and reduce processing time to achieve the desired DD and MW. These results help create a model that links chitosan quality, cost, and production scale in a waste-to-wealth approach. This method turns shrimp-processing waste into chitosan, reduces disposal problems, and supports a circular seafood economy.
