In medical applications wireless technologies are not widely spread. Today they are mainly used in non latency-critical applications where reliability can be guaranteed through retransmission protocols and error correction mechanisms. By using retransmission protocols within the disturbed shared wireless channel latency will increase. Therefore retransmission protocols are not sufficient for removing latency-critical wired connections within operating rooms such as foot switches. Todays research aims to improve reliability through the physical characteristics of the wireless channel by using diversity methods and more robust modulation. In this paper an Architecture for building up a reliable network is presented. The Architecture offers the possibility for devices with different reliability, latency and energy consumption requirements to participate. Furthermore reliability, latency and energy consumption are scalable for every single participant.
The present-day methods of numerical simulation offer a great variety of options for optimizing metal forming processes. Although it is possible to simulate complex forming processes, the results are typically available only as 2D projections on screens. Some forming processes have reached a level of complexity beyond the level of spatial sense, which makes it necessary to use physical 3D representations to develop a deeper understanding of the material flow, microstructural processes, process and design limits, or to design the required tooling. Physical 3D models can be produced in a short amount of time using 3D printing, and indexed with a wide range of colors. In this paper, the additive manufacturing of 3D color models based on simulation results are explored by means of examples from metal forming. Different 3D-printing processes are compared on the basis of quality as well as technical and economic criteria. Other examples from the fields joining by upset-bulging of tubes and microstructure simulation are also analyzed. This paper discusses the possibilities offered by the rapid progress and wide availability of 3D printers for the design and optimization of complex metal forming processes.
In safety critical applications wireless technologies are not widely spread. This is mainly due to reliability and latency requirements. In this paper a new wireless architecture is presented which will allow for customizing the latency and reliability for every single participant within the network. The architecture allows for building up a network of inhomogeneous participants with different reliability and latency requirements. The used TDMA scheme with TDD as duplex method is acting gentle on resources. Therefore participants with different processing and energy resources are able to participate.
Defining Recrutainment: A Model and a Survey on the Gamification of Recruiting and Human Resources
(2017)
Recrutainment, is a hybrid word combining recruiting and entertainment. It describes the combination of activities in human resources and gamification. Concepts and methods from game design are now used to assess and select future employees. Beyond this area, recrutainment is also applied for internal processes like professional development or even marketing campaigns. This paper’s contribution has four components: (1) we provide a conceptual background, leading to a more precise definition of recrutainment; (2) we develop a new model for analyzing solutions in recrutainment; (3) we present a corpus of 42 applications and use the new model to assess their strengths and potentials; (4) we provide a bird’s eye view on the state of the art in recrutainment and show the current weighting of gamification and recruiting aspects.
