Available Sampling Methods for Plastic Waste
Given the rapid development of plastics recycling in recent years, the need for guidelines for sampling and material characterization is steadily emerging. However, there still exists a considerable scarcity of methods that enable proper material data acquisition. It was found that neither the literature nor the standards provide a comprehensive practice that considers the distinctive characteristics of plastic waste and applies it to different situations along the value chain. Two variants of the proposed plan were evaluated based on the flake size distribution and the apparent density of four different pretreated polyolefin (PO) waste materials. Combining stratified random sampling with composite sampling yields a good sampling technique for rigid PO waste. Moreover, the analysis of a composite sample adequately conveys the true material properties of a sublot or lot.

Blockchain Technology in Automobile Supply Chain
A robust traceability system would help organizations in inventory optimization reduce lead time and improve customer service and quality which further enables the organizations to be a leader in their industry sector. The traceability issues and waiting time at different nodes of the supply chain are considered to be priority issues that affect the overall supply chain efficiency in the automotive supply chain. A new blockchain-based architecture was provided to improve traceability and reduce waiting time for the automotive supply chain.

Carbon Quantum Dots
Carbon dots have gained tremendous interest attributable to their unique features. Two approaches are involved in the fabrication of quantum dots (Top-down and Bottom-up). Most of the synthesis methods are usually multistep, required harsh conditions, and costly carbon sources that may have a toxic effect, therefore green synthesis is more preferable. Herein, the current review presents the green synthesis of carbon quantum dots (CQDs) and graphene quantum dots

Surface Defect Detection
Automated visual inspection (AVI) instrument targeting on surface quality emerges as a standard configuration for metal planar materials (e.g., steel, aluminum, copper plates and strips, etc.) to improve product quality and promote production efficiency. A general AVI instrument provides two main functions of defect detection and classification. The former detection process recognizes defective regions from normal background without identifying what types of defects they are. The latter process is dedicated to identify and label detected defects to support finishing product grading. The classification accuracy is directly determined by the precision of defect detection; thus, the overall performance of an AVI system is mainly limited by the accuracy, time efficiency, and robustness of various algorithms in the process of defect detection. Both two-dimensional and three-dimensional surface defect detection technologies are used for defect detection. According to the algorithm properties, the existing two-dimensional methodologies are categorized into four groups: statistical, spectral, model, and machine learning-based methods. On the basis of three-dimensional data acquisition, the three-dimensional technologies are divided into stereoscopic vision, photometric stereo, laser scanner, and structured light measurement methods.

Nano Copper Lubricant Additives
Nanoparticles have as characteristics super sliding, extreme pressure, self-healing, etc., which can improve the friction reduction and anti-wear performance of sliding components, when used as lubricating oil additives. Nano-copper particles have a good synergistic effect with other antifriction agents, anti-wear agents, antioxidants and grease additives because of their low shear strength and grain boundary slip effect, showing a better anti-friction and anti-wear effect. However, nanoparticles are prone to conglomerate, and this causes a bottleneck in the application of dispersant for nano-copper in a lubricating oil system. The regulation of nanosized effect and surface properties has great engineering significance in compensating for the precision in manufacturing accuracy.

Autonomous Haulage Systems
Mining is an industry that inherits the full advantage of Industry 4.0 by using cutting-edge driverless vehicles called Autonomous Haulage Systems (AHS) or Autonomous Haulage Trucks (AHT). These trucks can carry up to four hundred tons of ore and accurately transport it without human interaction. AHS is the state-of-the-art in the mining industry for autonomous vehicles.

Model-Based Enterprise Approach in the Product Lifecycle Management
Innovations in product development and process technologies represent a promising strategy to face the increasing competitiveness of modern markets in the global economy. Also, customer requirements become more and more specific and the complexity of products is still increasing. Industries need to adopt effective solutions during the product development process and to support, for sustainable purposes, all the phases of the product lifecycle. Advanced model-based solutions emerge for digitally supporting these industrial needs. In this context, a Model-Based Enterprise (MBE) represents an organization that adopts modeling technologies, such as Model-Based Definition (MBD) solutions, to integrate and manage both technical and business processes related to product design, production, support, and retirement. Past research discusses the model-based approaches focusing on technical product development, mainly referring to the design and the manufacturing phases.

A Product/Service System
Product/service system (PSS) is widely considered as a promising design object with the potential to enhance environmental sustainability of industrial solutions. The state of the art of PSS design research includes several prescriptive PSS design support tools, methods and procedures. This body of literature has been extensively reviewed in the past. However, there is a lack of consolidation of the available prescriptive knowledge in a condensed and practically useful format that can be used by practitioners to guide their conceptual PSS design activities and by researchers to build their work on. Thus, to address this gap in our knowledge, we use an intra-disciplinary literature analysis and meta-synthesis approach to consolidate the extant prescriptive PSS design knowledge in the form of a schema for conceptual PSS design.

Hydraulic Accumulators in Hydraulic Systems
Electric motors used in industrial machines and devices, as well as internal combustion engines (ICE) used in vehicles, mobile machines, and marine devices, participate in the transformation of mechanical power into hydraulic power. In power transmission, hydraulic drive systems have a high power density. Hydraulic pumps, as energy sources in hydraulic drive systems, are widely used due to their high working pressure and high flow rate. The hydraulic accumulator (HA) is a device that is used to store energy in the hydraulic system in the form of pressure energy.
