Transcritical–Transcritical Cascade CO2 Heat Pump with Expansion Work Recovery: A Thermodynamic Analysis

High-temperature heat pumps are a promising pathway for electrifying industrial process heat, but their application to large-temperature-glide duties remains technically challenging. Milk powder spray drying is one such application, requiring air heating to approximately 200 °C w...

Building inclusive learning communities: the collaborative role of parents and school leaders in supporting students with additional needs

Inclusive education is widely endorsed as a policy priority; however, less is known about how school leaders practically enable collaboration with parents to support inclusive schooling. This qualitative study examines how secondary school leaders enact and sustain collaboration...

Inscription of power dynamics in platformized classrooms. Exploring coded spaces of platform architectures through Participatory Action Research

Platforms contribute to the ‘world-making’ of education; they play a co-constitutive role by envisioning and inscribing the functionalities anticipated in education. As programmable digital architectures, they both shape and are shaped by teachers’ and students’ practices. Buildi...

Influence of the R-Ratio and the Temperature on the Coefficients of a Novel Exponential Approach for the Formulaic Description of Fatigue Crack Growth Rate Curves

Investigating crack growth in sheet metal originating from clinched joints is a major part of predicting the service life of mechanically joined structures. Clinching allows different materials to be joined together. A key task in this context is to perform crack growth simulatio...
