Learning to type with the tip of the tongue : a performance study for a tongue-computer interface

This study is motivated by the need to know the characteristics of the learning processes in tongue-computer interaction and to obtain a useful insight to a better design of the tongue-computer interface for computer text input. Tongue-typing can be a good alternative to hand input methods for physically disabled individuals or tasks where hand-typing is not possible. In order to evaluate the proc

L-Band 180 degree passive phase shifter employing auto-tranformer in an SOS process

In this paper, we present a new topology to implement a passive 180° phase shifter using on-chip auto-transformer in an SOS process. The measured results indicate a phase variation of less than 2° over the frequency range of 1.8-2.4GHz. An insertion loss of 2.3dB was measured at 2.1GHz. The phase shifter has a small footprint of 0.3 × 0.7mm2, which is almost three times less than a traditional hig

Svensk universitetsgrammatik för nybörjare

Svensk universitetsgrammatik för nybörjare behandlar begreppet grammatik ur olika synvinklar. De inledande kapitlen ägnas åt genomgångar av svenskans språkljud, böjningslära och ordbildning. I de efterföljande kapitlen ges ingående beskrivningar av frasstruktur, primära satsdelar och fullständig satslösning, liksom av grammatikens största enheter, meningar, makrosyntagmer och yttranden. Men förfat

Regulation of exocytosis by Ca2+ and cAMP - A study on pancreatic beta- and alpha-cells

Popular Abstract in Swedish Glukos är den främsta energikällan för de flesta celler i kroppen. Det är av stor vikt att mängden glukos hålls på en jämn nivå, eftersom framförallt våra celler i hjärnan är mycket känsliga för stora variationer av glukoshalten i blodet. Regleringen av mängden glukos i blodet kontrolleras av hormonen insulin och glukagon. Insulin utsöndras från beta-celler och glukagonType-2 diabetes is characterized by impaired insulin secretion associated with excess glucagon release. Exocytosis of insulin- or glucagon-containing granules is initiated by Ca2+-influx through voltage-dependent Ca2+-channels and is modulated by the second messengers such as cAMP. Membrane capacitance measurements were used in this study to investigate the cellular mechanisms behind cAMP-regulate

Lipid Self-Assembly and Lipase Action

In this thesis the action of the Thermomyces lanuginosa lipase (TLL) on "real" substrates, that is, lipid aggregates - vesicles, micelles, emulsions, gels and liquid crystals is discussed. Even for a pure triolein, the system becomes quite complex as the lipolytic process starts, both in terms of structure and composition, involving 5 additional components - diolein (DO), monoolein (MO), oleic aci

Learning Objects and their implications on Learning: a case of developing the foundation for a new Knowledge Infrastructure

In an era of lifelong learning, empowerment of the learner becomes fundamental. Therefore ex-ploitation of the full potential of learning objects depends upon creation of an appropriate infra-structure to promote symmetrical control of inquiry. The learner needs to be empowered because learning is a discovery process and thus must be under his or her own control. In early stages of education it

T cell Tolerance - Cellular and molecular features of immune regulation

Popular Abstract in Swedish Olika toleransmekanismer kontrollerar immunsystemets aktivitetThe immune system has evolved regulatory mechanisms in order to balance the effects of deleterious immune responses. Such immunological tolerance may be specifically acquired by lymphocytes, although different cells of the immune system participate in the induction and maintenance of tolerance. This thesis work is based on investigations of different tolerance mechanisms induced in CD4+ T lymphocy

Microscopical analyses of ceramic thin-sections of votive terracottas from Tessennano, Vulci, Tuscania and Tarquinia

Thin-section analysis of votive terracottas from the Etruscan sites Tessennano, Vulci, Tuscania and Tarquinia were made in order to help explaining the manufacturing process of votiv terracottas, with a focus on coice of raw material (clay and temper). The investigation of the material from these four sites has offered an opportunity to study Etruscan handicraft. The study has shown that e.g. that
