Assessment of Virtual-Reality-Based Digital Twins in Automotive Manufacturing Process Validation
… would take at least 21 weeks to create and study process digital twins using IC.IDO. Additionally the tool was found capable of simulating 9 out of 13 types of process on the assembly line. With limited time during the design validation phases it is necessary to prioritize which operations to …

Bayesian methods in non-clinical pharmaceutical statistics.
… sample size determination to the manufacturing process validation life-cycle. In particular, we show how the two-prior approach for sample size determination, which has been considered extensively in the clinical biostatistics area, can be applied to determine the number of commercial scale …

Recovery of Salmonella from Steam and Ethylene Oxide-Treated Spices Using Supplemented Agar with Overlay
… before ultimately reaching consumers. These processes may result in sub-lethal injury to cells, which can lead to an underestimation of microbial populations when plating on selective media. Sub-lethally injured cells are difficult to enumerate due to reduced ability to grow on selective …

Improving prior knowledge assessment in process characterization
… a safe, reliable and consistent manufacturing process. The manufacturing process design includes process characterization (PC) experiments to demonstrate process robustness and provide data necessary for planning, risk mitigation, development of the control strategy, and successful execution of …

An Investigation to Advance the Technology Readiness Level of the Centaur Derived On-orbit Propellant Storage and Transfer System
… of two specific objectives: (1) technique and process validation and (2) computational model development. In order to raise the Technology Readiness Level (TRL) of this technology, the corresponding FM techniques and processes must be validated in a series of experimental tests, including: …

Development of a design cycle for an additively manufactured aircraft rudder bracket
For traditional manufacturing processes, the variation of component quality and mechanical properties exists but these can be minimised by the implementation of process controls. Hence, it becomes key to define the full process for developing and manufacturing components. These processes have been …

To Enable the Processing of New Complex High Performance Alloys by Improving the Capacity and Performance of Continuous Casting Equipment
… <br/><br/>Comparison of the continuous casting process to other thermal methods such as continuous extrusion highlighted that, in general, the mechanical properties of continuous cast materials are lower than that of material from thermomechanical methods. However, continuously cast alloys rods …

Tooling performance in micro milling: Modelling, simulation and experimental study
… essential and much needed particularly for the process planning and optimization. The cutting performance of micro tools is largely dependent on the dynamic performance of machine tools, tooling characteristics, work material properties and process conditions, and the latter three aspects will …

Towards Cyber-Physical Security for Additively Manufactured Parts via In Situ Monitoring and Electromechanical Impedance
… geometries that cannot be made via traditional processes. AM is unique in its ability to precisely define both the material properties and geometric shape throughout the volume of a part, giving designers unmatched freedom in the creation of new components. However, this freedom of design also …

Validation of high pressure processing (HPP) as a suitable technology for the production of safe tender coconut water
La presente tesis evaluó el crecimiento potencial de Clostridium botulinum en agua de coco verde y caracterizó múltiples cepas de patógenos vegetativos (Escherichia coli O157:H7, Listeria monocytogenes y Salmonella enterica) en base a su fenotipo de resistencia a las altas presiones. Esto permitió …
