Additive Manufacturing Technology for Spare Parts Application
Spare parts management is an important part of many capital-intensive businesses, which have a direct impact on the availability of high-value capital assets. Lifecycles of advanced capital goods usually last many years, and more than 60% of their costs are related to management. Spare parts management of such goods is important because the downtime of the equipment for the lack of spare parts can cause a significant loss to the company.

Aerostatic Thrust Bearings
In aerostatic thrust bearings (ATBs), a high-pressure gas film with a certain bearing capacity and stiffness is formed by passing high-pressure gas between the moving surface and the static surface. Aerostatic bearings have outstanding advantages in the following aspects: high precision, high speed, and long service life, etc. They are widely used in many fields, such as high-speed air spindles, precision machine tools, air-bearing guideways, turbine machinery, and high-speed drills.

Aircraft Boarding Strategies
The pandemic caused by the COVID-19 virus (SARS-CoV-2) has been a source of concern for airlines regarding safe flight environments. The main reason is that infected people may experience no symptoms. Nevertheless, they may have high viral loads and spread the disease. To ensure the safety of passengers concerning virus propagation, such as COVID-19, and keep the turnaround time at low levels, airlines should seek efficient aircraft boarding strategies in terms of both physical distancing and boarding times.

Anaesthetic Vaporizer
An anaesthetic vaporizer is a device generally attached to an anaesthetic machine which delivers a given concentration of a volatile anaesthetic agent. It works by controlling the vaporisation of anaesthetic agents from liquid, and then accurately controlling the concentration in which these are added to the fresh gas flow. The design of these devices takes account of varying: ambient temperature, fresh gas flow, and agent vapour pressure.

Application of Two-fluid Mode
In two-fluid model (TFM), the granular flows are modeled as continuous fluid flows. The random motions of particles resulting from the interactive collisions of particles has a dominant effect on the flow behavior. The granular interactions are commonly modeled based on the kinetic theory of granular flow (KTGF).
