For this purpose a SOA architecture maturity framework has been developed, leveraging and extending CMMI and TOGAF, as well as other(More)
Capacitive electrodes have been studied as an alternative to gel electrodes, as they allow measurement of biopotentials without conductive contact with the patient. However, because the skin interface is not as precisely defined as with gel electrodes, this could lead to signal deformation and misdiagnoses. Thus, measurement of a capacitive coupling of the(More)
Abstract: The SOA Innovation Lab presents a holistic approach for the development of a service-oriented enterprise architecture with custom and standard software packages. Starting point is the construction and analysis of company domain maps with respect to characteristics of SOA and standard software. After assessing the SOA ability of standard software(More)
