Chemie Ingenieur Technik, EarlyView.This study explores the process chain for reverse engineering and additive manufacturing of a water pump impeller in a process plant. Key aspects include digital twin creation, CAD redesign, material certification, Hirtisation postprocessing, and performance testing. Insights highlight iterative design for improved precision and reliability.

Asymptotic diffusion analysis of RQ system M/M/1 with unreliable server
Discrete and Continuous Models and Applied Computational ScienceThe paper considers a single-line retrial queueing system with an unreliable server. Queuing systems are called unreliable if their servers may fail from time to time and require restoration (repair), only after which they can resume servicing customers.

A stochastic analysis of goods allocation by queuing and the prevention of violence [PDF]
When demand for a good exceeds its supply, queuing mechanisms are commonly used to allocate the good in question to citizens. However, very long queues result in excessive wait times and this can lead to violence. As such, the purpose of this paper is to

Health Care Science, EarlyView.We develop a patient flow model that integrates return loops and formulate a risk‐aware physician rostering framework designed to strictly enforce excess wait time targets, for example, tail probability of delay (TPoD) service levels. We employ a simulation‐based iterative staffing approach (ISA) to determine the optimal number of physicians required ...

On the allocation of commodities by queuing and the prevention of violence [PDF]
In times of acute scarcity, demand for a commodity greatly exceeds its supply. In such situations, queuing mechanisms are frequently used to allocate scarce goods to citizens.

The International Journal of Health Planning and Management, EarlyView.ABSTRACT Pakistan has hosted Afghan refugees for more than four decades, in one of the world's most protracted displacements of people. Afghan refugees receive health services through United Nations High Commissioner for Refugees (UNHCR) and non‐governmental organisation (NGO) supported programmes alongside public sector facilities at every tier.

The Optimal Deployment, Coverage, and Connectivity Problems in Wireless Sensor Networks: Revisited
IEEE Access, 2017 Finding an optimal node deployment strategy in wireless sensor networks (WSNs) that would reduce cost, be robust to node failures, reduce computation, and communication overhead, and guarantee a high level of coverage along with network connectivity is a
