The intrinsic stochasticity of manufacturing is one of the main factors that hinder system resilience. Planning and scheduling problems are typical examples plagued by various manufacturing uncertainties such as stochastic processing time, arrivals of new orders, and uncertain breakdowns of stations. Frequent uncertainties regarding operations and resources disturb the workflow, and their cascading effects create chaos in the whole system. The transparency and traceability in Cyber-physical manufacturing systems (CPMS) bring new hope to tackle uncertainties. Inspired by the core spirit of Out-of-Order (OoO) Execution in CPU, this paper proposes a novel OoO architecture, under which production and logistics operations are performed according to real-time executability, for resilient planning and scheduling of CPMS. Computational results have confirmed the effectiveness and resilience of the proposed solution under various uncertainties.

Compared with power frequency AC transmission and DC transmission, low frequency AC transmission has its unique advantages, which is suitable for long distance transmission, large scale renewable generation and regulation of regional power grid. The fault characteristics affect the system design and operation, which is necessary to study. From the perspective of system topology and converter control, the characteristics of three-phase short circuit fault are analyzed and a simulation model is built on PSCAD for verification in this paper. After a fault occurs, it can be divided into two stages before and after the control responses. Before the control responses, the overvoltage is generated between the terminals of branch reactors and modular capacitors discharges. After the control responses, system characteristics are related to fault location and control strategy. The control and modulation of the converter can make the low frequency and power frequency systems interact with each other. This study can provide a reference for the parameters of equipment and converter control, as well as fault protection in low frequency systems.

Poultry agriculture is a form of livestock farming that involves raising chickens, turkeys, ducks, etc, and raises them to provide eggs or meat. However, this work sheds light on the method of hatching duck eggs which maintains a suitable environment around the eggs through an automated and low cost device by controlling temperature (T) and relative humidity (RH). This paper presents a control strategy for automatic temperature and relative humidity control systems for the egg/s hatching procedure for rural areas people or unprivileged communities in the developing countries. One of the best outcomes of this work is the proper hatching procedure steps shown from the beginning to the end. Moreover, for a better understanding and outcomes, the research work has been done under a poultry farm in Charsita village, Lakshmipur, Bangladesh for 6 consecutive months of 2020. The experiment (egg/s hatching) has been conducted under an ice-box. Furthermore, a microcontroller (ATmega328p) is used to monitor the temperature and relative humidity by receiving data from the sensor DHT22 and manipulating the appropriate temperature and humidity using a logic algorithm code. Egg/s need a constant temperature and relative humidity of 35.6 °C to 37.8 °C and 60% to 80%, respectively. Nonetheless, an LCD (16*2) with a matrix keypad (4*4) has been integrated into the unit, allowing farmers to easily set, run, and monitor the appropriate temperature and relative humidity levels within the ice-box. Finally, the results of sensor testing, system device management, and performance rates are recorded to ensure the research's success. © 2021 IEEE.

Hydrogels are promising candidates for flexible electronics but are often constrained by narrow pressure-sensing ranges and unstable ion migration. To overcome these limitations, we developed an ionic hydrogel sensor incorporating diode-inspired bipolar architectures (PSSNa/PDACl) and poly(vinylidene fluoride)/carbon directional microchannels (PCDMC). The optimized 5-PCNPC hydrogel exhibits a broad pressure-sensing range (2.3–100 kPa) with a sensitivity of 0.360 mV·kPa−1 (a 35.6% enhancement) and a rectification ratio of 12.9, enabled by PCDMC-guided anisotropic ion transport and rapid stress dissipation (337 ms recovery). With excellent durability over 500 cycles and a power density of 1.17 mW·m−2, the hydrogel sensor demonstrates its potential in practical applications, including a 5×5 touchpad for spatial pressure mapping and real-time monitoring of respiration, swallowing, and locomotion. This study underscores the potential of hydrogel-based sensors with wide-range operability for next-generation wearables and interactive systems. © 2025, The Authors. All rights reserved.

Wearable triboelectric nanogenerators (TENGs) with high electrical performance have recently prompted great expectations. However, charge diffusion and recombination affect the electric field strength, resulting in a weak electrostatic potential in the displacement region. Current research on film-type dielectric interlayers indicates that charge trapping can prevent charge recombination, although surface charge air breakdown has not been addressed, and becomes a crucial demand in wearable energy applications. In the present study, the surface charge density of poly(vinylidene fluoride) (PVDF) nanofibers is greatly improved by co-electrospraying PDMS-PVDF (PDPV) charge-trapping microbeads;this new approach prolongs the lifetime of surface charges. In particular, the PDPV beads prevent charge recombination, and the interlocking mechanism enhances the tensile property of the PVDF nanofibers. These result in a two-fold increase in the open-circuit voltage and peak power density to 305 V and 124.3 mW m−2, respectively. The device is successfully employed in portable electronic gadgets. Ag-nanoparticle-grafted styrene-butadiene-styrene (SBS) fiber is used as an electrode because it has favorable stretchability with low resistance and is antibacterial. The addition of TiO2/multiwalled carbon nanotube to PVDF nanofiber membrane shows excellent electricfield-induced photocatalyst and ultraviolet protection. Our surface-enhanced fully fiber-based TENG is a promising energy harvester for flexible smart garments applications. © 2023 Elsevier Ltd

Production scheduling of semiconductor manufacturing tools is a challenging problem due to the complexity of the equipment and systems in modern wafer fabs. In our study, we focus on the photolithography toolset and consider it as a non-identical parallel machine scheduling problem with random lot arrivals and auxiliary resource constraints. The proposed methodology strives to learn a near optimal scheduling policy by incorporating WIP, masks, and the tardiness of jobs. An Action Filter (AF) is proposed as a methodology to eliminate illogical actions and speed the learning process of agents. The proposed model was evaluated in a simulation environment inspired by practical photolithography scheduling problems across various settings with reticle and qualification constraints. Our experiments demonstrated improved performance compared to typical rule-based strategies. Relative to our learning methods, weighted shortest processing time (WSPT) and apparent tardiness cost with setups (ATCS) rules perform 28% and 32% worse for weighted tardiness, respectively. © 2021 IEEE.

The mechanical performance of FDM-printed high-performance polymers like carbon fibre-reinforced PEEK remains sensitive to process parameters, limiting their reliability in structural applications. The present study addresses this challenge by investigating the influence of printing speed, layer thickness, and infill density on tensile, flexural, and compressive strengths. Using Response Surface Methodology (RSM) and Taguchi analysis, predictive models were developed and statistically validated through ANOVA. The models were highly reliable, with R 2 values above 0.94 across all strength modes. Print speed and infill density had the greatest impact on tensile, flexural and compression strength, while layer thickness also played a significant role. Lower printing speeds and higher infill densities resulted in strength materials with better interlayer adhesion and fewer internal defects. The models can improve the mechanical performance of FDM printed parts by optimising process parameters across multiple objectives. This research has significant implications for aerospace, biomedical, and structural applications that require reliable and strong components.

Fast skin repair is critical for less infection, less pain and high quality of life, which is still limited with undesirable rehabilitation speed and side effects. Currently, laser-activated silk sealant agent without suture and gauze has been demonstrated promising for fast skin repair taking advantage of its structural transformation after heating. Nevertheless, more efficient healing effects and less side effects of laseractivated silk sealant agent remains challenging due to absence of suitable photo-thermal materials and robust/biomimetic protein materials. In this work, the marriage between silk protein and Rehmanniae radix preparata(a kind of the traditional Chinese herb) has been demonstrated as a novel and effective way to achieve an excellent healing effect for skin repair. The non-toxicity, high photothermal conversion efficiency and healing mechanism are systematically studied and proved. This new methodology might shed a new light for combining dark traditional Chinese medicine and silk fibroin for advanced wound healing technology.
