Base Station Energy Optimization with Big Data Analytics.
Project participants:Advanced mathematical methods and software platform for solving multiphysics, multidomain problems on modern computer architectures: applications to environmental engineering and medical problems.
Project participants:Continuous Transistor Sizing Toolset for nanoscale IC optimization
Project participants:iMuse project exploited the recent advances in web and RFIDs to create a new model of a virtual museum. Three new services were developed for museum visitors.The project is deployed at Archeological Museum of Volos, Greece.
Project participants:Main objective of the project was the development of a telemedical system for better support and faster management of amputation cases in the extremities,in patients who can possibly be transferred to the University Hospital of Larissa.
Project participants:A platform for rapid prototyping of e-textile applications, that monitor human activities, was introduced. The platform comprises a toolbox named MoDA for studying human motion data and a hardware infrastructure for building e-textiles.
