Additive manufacturing (AM) is replacing traditional manufacturing approaches – such as subtractive and molding – in some industries. The product and supply chain impacts of AM continue to extend its industrial reach, improve engineer-to-order manufacturing, and pave the way to mass customization. This study explores the supply chain changes that may arise from a full or partial transition to AM-based ...

As a disruptive technology, additive manufacturing (AM) is revolutionizing manufacturing supply chains. AM consists of producing 3-dimensional objects through layer-by-layer addition of compound material based on digital models. The scheduling of additive manufacturing operations differs from traditional (i.e., subtractive and injection molding) manufacturing with a single production run involving ...

From the perspective of Resource-based Theory (RBT), organizational culture can be a source of sustained competitive advantage. And resources integration models, divided by property rights of resource, not firm boundary, as internal and external resources integration models, are presented as being specific in different cultural contexts. However, the litera- ture review shows the absences of an ...

The vision behind industry 4.0 is to create even smarter manufacturing facilities. Industry 4.0 includes both hardware and software components, which are expected to seamlessly interact in a secure manner. Thus, machinery and software components from different manufacturers should be able to communicate in a common language. Such a challenge is typically met by introducing a “middleware” to serve ...

Atmospheric icing on structures has proven to be an area of concern in many cold climate geographical regions like arctic and alpine. Difficulties encountered by the communication, construction and power industries in these areas are the subject of intense investigations for researchers from decades. Three main methods of investigation are generally employed by researchers to study atmospheric ice ...

Ice accretion on railway overhead contact wires/conductors can cause various critical operational and safety issues such as overloading, arc formation, mass imbalance, and wire galloping. The focus of this multiphase numerical study is to understand and analyze the ice accretion physics on railway overhead powerline conductors at various operating conditions. In this regard, two different ...

The application of capacitive sensing technique is widely distributed in different physical domains primarily because of the diversity in dielectric permittivity and due to its minimum loading error and inertial effects. Atmospheric ice is a complex mixture of water, ice and air which is reflected in its complex dielectric constant. There are many existing atmospheric icing sensors but only few are ...

With the emergence and the widespread of the COVID-19 pandemic across the globe, there is an urgent need to effectively control the disease spread through mass vaccination. Several COVID-19 vaccines, e.g., Pfizer/BioNtech and Moderna, etc., have been proven highly effective and have been distributed and administrated in many countries. These vaccines need to be produced in large quantities and ...

The scope of this study comprehends problems associated with modern urban vehicles known as cable propelled gondolas system operations in icing conditions. The aspects under consideration are problems related to the operations, safety, and maintenance of cable car systems in harsh climate conditions. The geographical location of the gondola cars makes them vulnerable to severe weather conditions ...

Non steady state thermal conductivity of ABS was estimated using an analytical approach in a Cold Climate Chamber at ?10?C and ?14?C. Two hollow cylinders of ABS of varying thickness were used to estimate the conductivity. The material was porous but the porosity was unknown. This paper is a case study to understand, if it is reasonable to estimate the thermal conductivity using the analytical varying ...
