This study introduces a learning-assisted denoising technique for skin Optical Coherence Tomography (OCT) images. By combining Reinforcement Learning (RL) with the Denoising Convolutional Neural Network (DnCNN), we achieve enhanced denoising capabilities. The method iteratively refines DnCNN parameters through RL-guided policies, demonstrating superior performance. Tailored for skin OCT images, the approach prioritizes preserving vital structures for accurate clinical assessments. This integration of RL into DnCNN training represents a promising advancement in medical image denoising, particularly for dermatological diagnostics. © 2024 SPIE.

Gafur, M.A. Department of Materials and Metallurgical Engineering Bangladesh University of Engineering and Technology Dhaka 1000 Bangladesh Pilot Plant and Process Development Centre Bangladesh Council of Scientific and Industrial Research Dhaka 1205 Bangladesh Department of Applied Chemistry and Chemical Engineering University of Dhaka Dhaka 1000 Bangladesh

Zirconia toughened alumina (ZTA) is one of the widely discussed advanced ceramic in recent times. ZTA boasts excellent mechanically properties such as high hardness, high strength. Additionally, the material is chemically inert and possess greater compressive strength. Despite having such versatility, lack of fracture toughness and shock resistance prevent its utilization in broad scale. To improve the fracture toughness and other mechanical properties, metals, metallic oxides additives such as MgO, CaO, CeO2, Cr2O3, strontium hexa-alumina, Ag, Ni, FeO were commonly added to ZTA in the academic research. The purpose of this review paper is to provide a wholistic perspective on the trend of mechanical property alteration upon addition of different additives. Trend of mechanical property alteration such as density, fracture toughness, microhardness, strength provide a comparative analysis to solve this critical research and industrial problems. © 2022

In automotive body-in-white production, geometry determining clamping technology is used. In order to counter deviations from the target geometries, fixtures are adjusted manually in an experience-based process that comprises iterative loops. Lately, AI based approaches have led to the question if they may reduce the time and material requirements of this process. This work provides an overview of literature that employs control methods for predicting adjustments of body shop fixtures. Applicability into automotive series production is evaluated and open requirements defined. Results show that there are multiple strategies that may help improve fixture adjustments in automotive industry. © 2024 Elsevier B.V.. All rights reserved.

As the chemical industry shifts toward sustainable practices, there is a growing initiative to replace conventional fossil-derived solvents with environmentally friendly alternatives such as ionic liquids (ILs) and deep eutectic solvents (DESs). Artificial intelligence (AI) plays a key role in the discovery and design of novel solvents and the development of green processes. This review explores the latest advancements in AI-assisted solvent screening with a specific focus on machine learning (ML) models for physicochemical property prediction and separation process design. Additionally, this paper highlights recent progress in the development of automated high-throughput (HT) platforms for solvent screening. Finally, this paper discusses the challenges and prospects of ML-driven HT strategies for green solvent design and optimization. To this end, this review provides key insights to advance solvent screening strategies for future chemical and separation processes. © 2025 The Authors.

Lab-on-a-Chip (LOC) products for point-of-care diagnostics have gained significant attention. However, there is a lack of systematic approaches for LOC product development. To address this, we introduce an Attribute Dependency Graph exemplary for a magnetophoretic LOC system for pathogen detection. This model organizes dependencies between the design variables and crucial quantities of interest, such as detectability, cost per test, and test duration. The obtained model helps to manage design complexity and can be adapted to other LOC approaches. © 2024 Proceedings of the Design Society. All rights reserved.

Objectives: This paper presents the development of a graphical user interface which supports the traceability evaluation in PTC Integrity, by displaying the dependency tree, to facilitate consistency and impact analysis in Automotive SPICE standards. Methods: Qualitative and quantitative experimental design and agile development methods were used to identify problems and potential solutions, and user requirements were gathered and analysed thematically. Results: Conceptual ideas for the visualisation and configuration were offered, and keeping the limitations in mind, the dependency tree tool was developed. The scope for future development was also provided. Conclusions: The developed tool is beneficial in automotive development by saving time in impact analysis and improving consistency. © 2023 IEEE.

To alleviate the secondary contamination of our environment when using quantum dots(QDs) to detect the organophosphorothioate pesticides(OPPs),we herein report a strategy to assemble magnetic Fe_(3)O_(4) nanoparticles and luminescent Cd Te quantum dots(QDs) into a composite nanosystem,which possesses both the magnetic property of Fe_(3)O_(4) nanoparticles and the luminescent character of Cd Te QDs,for the detection of chlorpyrifos,one of the typical *** strategy involves the isolated synthesis of magnetic Fe_(3)O_(4) nanoparticles with positive charges and luminescent Cd Te QDs with negative charges,and their subsequent assembly by electrostatic *** as-prepared Fe_(3)O_(4)-Cd Te nanocomposites have a detection limit as low as 10 ppb for chlorpyrifos,and are also selective for the OPPs with a phosphorothioate moiety(P=S bond).In specific,the Fe_(3)O_(4)-Cd Te nanocomposites can be conveniently harvested by a normal magnet,and the recycling rate for both Cd and Fe determined by inductively coupled plasma atomic emission spectroscopy(ICP-AES) is higher than 96%,showing great potential in alleviating the Cd pollution on the environment.
