QR code capacity and anti-counterfeiting is an important problem that needs to be solved. Based on the application requirements of large-capacity and anti-counterfeiting 2D codes, this study generates largecapacity color 2D codes by using primary and mixed colors multiplexed into the 2D codes, based on the RGB triple color equation, encoded by grayscale encoder, and realizing multi-code composite information modulation. The proposed color two-dimensional code can be read directly by the reading device, and through the computer color filtering software color filtering processing, the composite implanted secret two-dimensional code can be read separately, so as to realize the high-capacity integration and anti-counterfeiting function.

This paper presents the conceptualization and realization of an innovative, intelligent system for recycling wet waste, engineered to offer a compact, mobile, and automated approach to kitchen waste management. The system simplifies the entire process of waste treatment, encompassing bag opening, collection, fermentation, and storage as fertilizer. Key functionalities include: automatic garbage bag disposal, freeing users from direct contact with waste; resource recovery by converting waste into compost or biogas, contributing to a circular economy; and smart technology integration that enables tracking and promotes user engagement in the recycling process. Designed primarily for small-scale settings such as individual homes or small businesses, the system promotes sustainability by boosting recycling rates and diminishing overall household waste.

The ongoing high rate of construction project failures worldwide is often blamed on the difficulties of managing stakeholders. This highlights the crucial role of strategic management (SM) in achieving project success. This study investigates how integrating digital tools into the SM framework can effectively address stakeholder-related challenges. This work specifically focuses on the impact of evolving digital tools, such as Project Management Software (PMS) (e.g., Basecamp and Wrike), Building Information Modeling (BIM) (e.g., Tekla BIMsight and Autodesk Navisworks), Virtual and Augmented Reality (VR/AR) (e.g., Microsoft HoloLens), drones and remote monitoring, and social media and Web-Based platforms, in improving stakeholder engagement and project outcomes. Through existing literature with examples of failed projects, the study highlights how the evolution of digital tools will serve as facilitators within the strategic management process. These tools offer benefits such as real-time data access, enhanced visualization, and more efficient workflows to mitigate stakeholder challenges in construction projects. The findings indicate that integrating digital tools with SM principles effectively addresses stakeholder challenges, resulting in improved project outcomes and stakeholder satisfaction. The research advocates for a combined approach that embraces both strategic management and digital innovation to navigate the complex stakeholder landscape in construction projects.
