At the present time, the most widely used commercial rapid prototyping (RP) processes are
based on polymeric materials, such as plastics or photocurable resins. While these prototype …

Heavy metal toxicity has become a pressing ecological problem that affects the ecosystems
through bioaccumulation, representing a serious public health hazard. Many conventional …

The arc weld pool is always deformed by plasma jet. In a previous study, a novel sensing
mechanism was proposed to sense the free weld pool surface. The specular reflection of …

Dairy cows with ketosis are characterized by oxidative stress, hepatic damage, and
hyperketonemia. Acetoacetate (AA) is the main component of ketone bodies in ketotic cows, and is …

This paper presents an innovative investigation on prototyping a digital twin (DT) as the
platform for human-robot interactive welding and welder behavior analysis. This human-robot …

This research assesses the effectiveness of China's green credit policy. We explore whether
firms with better external environmental disclosure and internal green innovation receive …

The 3D weld pool surface in gas tungsten arc welding (GTAW) is characterized by its width,
length, convexity and measured in real-time using an innovative machine vision system. The …

The structural, electronic, and optical properties of β-Ga 2 O 3 with oxygen vacancies are
studied by employing first-principles calculations based on density function theory. Based on …
