At same time, various national development strategies have been put forward, Industry 4.0, Industrial Internet, based on Cyber-Physical System, Made in China 2025. However, one specific challenges to achieve with these how converge physical world virtual world, so realize series operations process, including...

With the advent of new generation information technologies in industry and product design, big data-driven design era has arrived. However, mainly places emphasis on analysis physical data rather than virtual models, other words, convergence between space is usually absent. Digital twin, a emerging fast growing technology which connects world, attracted much attention worldwide recently. This paper presents method for based digital twin approach. The development briefly introduced first....

Human-machine interaction (HMI) is a key technology for implementing smart manufacturing, which primarily focuses on the issues of communication, interaction, and cooperation between humans machines. HMI has been widely studied in product lifecycle including design, service, but efficiency safety still cannot meet new requirements manufacturing along with emerging technologies (e.g., big data, artificial intelligence, augmented reality, etc.). Digital twin (DT), as to realize cyber-physical...

Composite materials are widely used in many fields due to their excellent properties. Quality defects composite can lead lower quality components, creating potential risk of accidents. Experimental and simulation methods commonly predict the materials. However, it is difficult accurately uncertain curing environment incomplete feature space. To address this problem, a digital twin (DT) visual model material first constructed. Then, static autoclave DT virtual coupled with variable construct...

In this paper, we present an unstructured peer-to-peer network called GridMedia for live media streaming employing a push-pull approach. Each node in randomly selects its neighbors the overlay and uses method to fetch data from neighbors. The pull mode which is inherently robust can work well with high churn rate P2P environment while push efficiently reduce accumulated latency observed at user nodes. A practical system based on framework has been developed. And performance evaluation of our...

We describe the design and implementation of unstructured peer-to-peer networks for large-scale live media streaming through global Internet in this paper. In so called GridMedia system, we adopt gossip-based protocol to organize end nodes into an application layer overlay. Each node independently selects its neighbors utilizes a novel efficient push-pull mechanism fetch data from with low latency little redundancy. The traditional pull mode overlay has inherent robustness high churn rate...

Poly(lactic acid) (PLA), one of the most promising biodegradable polymer products, has achieved wide applications for its relatively good mechanical properties and moderate degradability. Here we report an environment-friendly filler, organic–inorganic composite Janus nanosheets (PLA/PBS JNs), which can jam at interface PLA/PBS blend with a low threshold as compatibilizer simultaneously toughen composites improve gas barrier performance due to better interfacial interaction tortuous path...

The fusion of emerging technologies with industrial design has catalyzed a fundamental shift in the aesthetics, user experiences, and service frameworks products Industry 4.0 era. Simultaneously, this convergence heightened demands placed on technological integration competencies designers. Consequently, there exists necessity to articulate precise developmental trajectory for proficiency that incorporates these novel technologies. This study initiates bibliometric analysis quantify...

The Internet has witnessed a rapid growth in deployment of data-driven overlay network (DON) based streaming applications during recent years. In these applications, each node independently selects some other nodes as its neighbors (i.e. construction), and exchanges data with scheduling). This scheme improves the robustness system. However, most work literature focused on construction problem, very few addressed scheduling problem which is also important for overall performance. this paper,...

Due to the increasing consumption of food products and demand for quality safety, most processing facilities in United States utilize machines automate their processes, such as cleaning, inspection grading, packing, storing, shipping. Machine vision technology has been a proven solution grading since late 1980s. The remaining challenges, especially small midsize facilities, include system operating costs, high-skilled workers complicated configuration operation and, some cases,...

We present a novel single source peer-to-peer multicast architecture called GridMedia which mainly consists of 1) multi-sender based overlay protocol (MSOMP) and 2) redundancy-retransmitting algorithm (MSRRA). The MSOMP deploys mesh-based two-layer structure groups all the peers into clusters with multiple distinct paths from root to each peer. To address problem long burst packet loss, MSRRA is proposed at sender patch lost packets by using receiver peer loss pattern prediction....
