Personal multimedia databases contain thousands of items and other databases on the Internet may contain even billions of items. Finding a particular item manually from such databases becomes overwhelming and thus automatic ...
This thesis proposes signal processing methods for analysis of singing voice audio signals, with the objectives of obtaining information about the identity and lyrics content of the singing. Two main topics are presented, ...
Competitive intelligence process aims to provide actionable information about the external business environment to back up decision-making in companies. The affects that the rise of social media may have on competitive ...
Quality improvements in small and medium-sized software organisations can be done in many ways. Companies can try to implement one of the well-established quality improvement frameworks. However, many reports from practitioners ...
More than 1000 jointless bridges have been built in Finland during recent decades. The maximum length of a symmetrical road bridge has been 70 meters, that is, 35 m + 35 m from the centre of thermal movements.
Integral ...
The current trend is going more and more towards IP-based delivery for all kind of digital content. At the same time, the increasing quality of the digital media is simultaneously increasing the size of the media, which ...
The life cycles of mobile control electronics are significantly longer than in the mainstream electronics. The low production quantities and high number of product variants together with long life cycles has led to scattered ...
Liiketaloustieteellisessä väitöstutkimuksessani analysoin maailman paperi- ja sellukonetoimialan kehitystä 1970-luvulta 2000-luvulle. Alaa edustavat suuret menestyneet yritykset Metso (Valmet), Andritz, Voith ja Kværner ...
Stochastic optimization (SO) represents a category of numerical optimization approaches, in which the search for the optimal solution involves randomness in a constructive manner. As shown also in this thesis, the stochastic ...
In this thesis the sensorless control of a permanent magnet synchronous motor (PMSM) is studied. The study has two main purposes. The first is to find a simple and effective method to estimate the rotor position and angular ...
In this thesis we develop a state space output regulation theory for linear infinite-dimensional systems and bounded uniformly continuous exogenous reference/disturbance signals. The output regulation problems that we study ...
In this thesis we consider model selection (MS) and its alternative, model averaging (MA), in seven research articles and in an introductory summary of the articles. The utilization of the minimum description length (MDL) ...
The target of this study was to establish statistical prediction models for the water vapour transmission rate (WVTR) of extrusion-coated papers and paperboards commonly used in food packaging. The models bring along ...
How should we react to dynamically changing inputs in various areas of computer science? This is one of the main questions we discuss in this thesis. The problem is present both in machine learning environment coping with ...
The mechanical behavior of metastable austenitic steels can be relatively complex in terms of temperature and strain rate sensitivity. This is connected to their low stacking fault energy and tendency towards martensitic ...
There are more than 20,000 bridges in Finland, of which about 2000 with a sum of span lengths over 20m are actual integral abutment road bridges. The lower building and maintenance costs of integral abutment bridges compared ...
The Digital Video Broadcasting Project (DVB) is a multinational initiative to standardize digital broadcasting worldwide. It produces different system specifications including satellite: DVB-S, cable: DVB-C, terrestrial: ...
In this Thesis, technologically important III-V semiconductors are studied. Structural and electronic properties of bismuth (Bi) stabilized InP(100) and GaAsN(100) are explored. Atomic models for the Bi-stabilized surfaces ...
Printed electronics (PE) is based on printing thin- and thick-film structures on cost-sensitive flexible substrates, such as paper-like, plastic, and on rigid substrates using a novel approach to manufacturing electronics ...
The digital convergence has brought about a new class of mobile devices that allows a compelling, visually rich multimedia experience to the user in a handheld product, such as a mobile telephone. The display in these ...
