In this work, we developed a geometric computational method for electromagnetic wave problems. The method unifies the spatial and temporal discretizations and produces a four-dimensional spacetime computational scheme, ...

This thesis concerns stable repetition rate, Q-switched fiber lasers using semiconductor saturable absorber mirrors (SESAMs) as elements triggering pulse operation. The nonlinear reflectivity responses of the SESAMs have ...

The topic of this thesis is discrete tubular truss optimization using heuristic multipurpose algorithms. The multicriteria topology, shape and sizing optimization problem has been formulated based on practical real life ...

Development of high-speed electronic and optoelectronic devices based on semiconductor quantum wells requires clear understanding of the dynamics and kinetics of carrier transport and relaxation on an ultra short time ...

In this thesis we report on the experimental studies on the generation of ultrashort pulses from mode-locked ytterbium fiber lasers operating at 1 mm wavelength region. Different fiber cavities, all with a linear geometry, ...

The aim of this thesis is to provide new empirical knowledge and case solutions to the domain of user and platform adaptive learning environments. The studies of the thesis were based on reviews of literature, technological ...

Although high sensitivity receiver technology is necessary to ensure sufficient observation availability of satellite navigation in degraded signal environments, processing of high sensitivity data observed in deteriorated ...

The concept of ‘value’ has received extensive interest in research in the fields of psychology, marketing and, more recently, human-computer interaction (HCI). Gaining insights into users’ personal values can lead to a ...

Kaupunkisuunnittelun kansainvälisessä keskustelussa on kymmenen viime vuoden aikana vakiintunut käsitys siitä, että kaupungit ovat tulleet uuteen kehitysvaiheeseen. Sen myötä kaupungit ovat muuttuneet sekä laadullisesti ...

Modern digital music services and applications enable easy access to vast online and local music collections. To differentiate from their competitors, software developers should aim to design novel, interesting, entertaining, ...
