This paper presents an implementation of technical-measurement standard interfaces to an embedded FPGA-based system. The system itself is a universal platform for various physical measurements. In particular the application for a device for non-destructive testing of materials is presented. The device can also work in areas such that the ultrasonic, e.g., nuclear magnetic resonance (NMR) field. The...
In the development of new device concepts a lot of aspects are to consider. On the one hand there is the needing for a lot of channels which are fully synchronized with hard real-time behavior; on the other hand there are the requirements for the implementation of modern communication protocols such TCP/IP or USB to assure a full interoperability with the state-of-the-art communication infrastructure...
Recent investigations on elastic behaviour, using uniaxial compression measurements of the swelling degree of poly(dimethylsiloxane) rubber (PDMS) networks lead to the assumption that a transition from the affine to the free-fluctuating phantom network occurs. To study the swelling process in different solvents, PDMS networks with different crosslink densities, molecular weight distributions and memory...
Abstract. A complex aging regime takes place in the course of thermal aging of natural rubber. Depending on the kind and the content of the free crosslinker, the aging temperature, the duration of the aging period and the reactivity of the atmosphere (air or nitrogen) a different aging process can be observed also by NMR. The methods used are the common spin-echo-NMR (1H) and parameterselective NMR-imaging...
