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.

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.

Various proteins involved in replication, repair, and the structural organization of mitochondrial DNA (mtDNA) have been characterized in detail over the past 25 or so years. In addition, in recent years, many proteins were identified with a role in the dynamics of the mitochondrial network. Using advanced imaging and an increasing number of cytological techniques, we have begun to realize that an important aspect to mtDNA maintenance, in both health and disease, is its organization within the dynamic mitochondrial network in discrete protein-DNA complexes usually termed nucleoids. Here, I review recent developments in the study of nucleoid dynamics and proteins. I will discuss the implications of the organization of mtDNA in nucleoids in light of DNA replication, repair, gene expression, segregation, and inheritance. © 2009 IUBMB.

Ad Hoc Networks | Year: 2012
To account for stochastic properties when modeling connectivity in wireless mobile systems such as cellular, ad hoc and sensor networks, spatial point processes are used. Since connectivity can be expressed as a function of the distance between nodes, distance distributions between points in spatial processes are of special importance. In this paper, we survey those results available for distance distributions between points in two mostly used spatial point models, namely, the homogeneous Poisson process in R 2 and independently uniformly distributed points in a certain region of R 2. These two models are known for decades and various distance-related results have been obtained. Unfortunately, due to a wide application area of spatial point processes they are scattered among multiple field-specific journals and researchers are still wasting their time rediscovering them time after time. We attempt to unify these results providing an ultimate reference. We will also briefly discuss some of their applications. © 2012 Elsevier B.V. All rights reserved.

Companies struggle with the sub-optimization and changes among their projects, even if various normative instructions and good practices have been introduced for project portfolio management. At the center of this paper is the need to understand project portfolio management in practice and in context. The purpose is to report a review on recent empirical research literature regarding project portfolio management, to draw attention to the limitations with viewing portfolio management as a rational decision process, and to develop new avenues for research regarding project portfolio management in practice and in context. As a result, this paper shows that, to respond to uncertainties and complexities in business environments, project portfolio management can be viewed as negotiation and bargaining and as structural reconfiguration, besides rational decision processes. These alternative perspectives offer new insight into the dilemmas identified in day-to-day project portfolio management and open up avenues for resolving them, thereby promoting success in project portfolio management. © 2012 Elsevier Ltd and IPMA.

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.

Brain Topography | Year: 2012
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.
