Tampere, Finland

Tampere University of Technology ) is Finland's second-largest university in engineering science. The university is located in Hervanta, a suburb of Tampere.The university's statutory duty is to pursue research and give the highest education in its field. The research, conducted by some 1,800 staff and faculty members, mostly focuses on applied science and often has close ties to many different companies . Located next to the university campus is a Technology Centre Hermia, including a large Nokia research facility. The yearly budget of the university is some 147 million euros. TUT is one of the only two Finnish universities which operate as foundation. Close to 50% of its budget is external funding. Wikipedia.


The present invention relates to the field of electrotherapy and measuring by means of electric currents for diagnostic purposes, and more particularly to an electrode arrangement for facilitating wound healing, a method for measuring wound healing and a wound dressing having an electrode arrangement. A wound dressing according to the present invention comprises at least two impedance reference electrodes, a frame like counter-electrode and stimulation electrodes in a form of an array; and a bioadhesive affinity layer surrounding the stimulation electrodes; said wound dressing being suited for applying on top of the wound so that the stimulation electrode array is on the wound area, and that the at least two impedance reference electrodes and the frame like counter-electrode are suited for placing in contact with the healthy skin surrounding the wound area; which electrodes, are suited for applying LIDC type electrical stimulation current to the wound area and for bioimpedance measurement. The wound dressing according to the present invention provide a continuous, non-invasive and objective solution for monitoring chronic wound healing without disturbing the delicate healing process.

Since the detection of the first biomagnetic signals in 1963 there has been continuous discussion on the properties and relative merits of bioelectric and biomagnetic measurements. In this review article it is briefly discussed the early history of this controversy. Then the theory of the independence and interdependence of bioelectric and biomagnetic signals is explained, and a clinical study on ECG and MCG that strongly supports this theory is presented. The spatial resolutions of EEG and MEG are compared in detail, and the issue of the maximum number of electrodes in EEG is also discussed. Finally, some special properties of EEG and MEG methods are described. In brief, the conclusion is that EEG and MEG are only partially independent and their spatial resolutions are about the same. Recording both of them brings some additional information on the bioelectric activity of the brain. Thesetwo methods have certain unique properties that make either of them more beneficial in certain applications. © 2011 Springer Science+Business Media, LLC. Source

Computer Science Review | Year: 2010

This survey investigates search-based approaches to software design. The basics of the most popular meta-heuristic algorithms are presented as background to the search-based viewpoint. Software design is considered from a wide viewpoint, including topics that can also be categorized as software maintenance or re-engineering. Search-based approaches have been used in research from the high architecture design level to software clustering and finally software refactoring. Enhancing and predicting software quality with search-based methods is also taken into account as a part of the design process. The background for the underlying software engineering problems is discussed, after which search-based approaches are presented. Summarizing remarks and tables collecting the fundamental issues of approaches for each type of problem are given. The choices regarding critical decisions, such as representation and fitness function, when used in meta-heuristic search algorithms, are emphasized and discussed in detail. Ideas for future research directions are also given. © 2010 Elsevier Inc. Source

When light interacts with metal nanostructures, it can couple to free-electron excitations near the metal surface. The electromagnetic resonances associated with these surface plasmons depend on the details of the nanostructure, opening up opportunities for controlling light confinement on the nanoscale. The resulting strong electromagnetic fields allow weak nonlinear processes, which depend superlinearly on the local field, to be significantly enhanced. In addition to providing enhanced nonlinear effects with ultrafast response times, plasmonic nanostructures allow nonlinear optical components to be scaled down in size. In this Review, we discuss the principles of nonlinear plasmonic effects and present an overview of their main applications, including frequency conversion, switching and modulation of optical signals, and soliton effects. © 2012 Macmillan Publishers Limited.
