Characterization and application of analysis methods for ECG and time interval variability data
Author(s) :
Tikkanen, Pauli
Description :
Abstract
The quantitation of the variability in cardiovascular signals provides information about
the autonomic neural regulation of the heart and the circulatory system. Several factors
have an indirect effect on these signals as well as artifacts and several types of noise are
contained in the re...

Integrated receiver channel circuits and structures for a pulsed time-of-flight laser radar
Author(s) :
Ruotsalainen, Tarmo
Description :
Abstract
This thesis describes the development of integrated structures and circuit implementations for the receiver channel of portable pulsed time-of-flight laser rangefinders for industrial measurement applications where the measurement range is from ∼1 m to ∼100 m to noncooperative targets and ...

Habitat requirements of juvenile salmonids : towards ecologically-based fisheries management in boreal streams
Author(s) :
Mäki-Petäys, Aki
Description :
Abstract
For effective management of stream salmonids, it is essential to (i) assess the productive potential of a stream in relation to species-specific habitat requirements, and to (ii) identify the key factors underlying any bottleneck periods during the life cycle of a fish. For this purpose, t...

Biocompatibility evaluation of nickel-titanium shape memory metal alloy
Author(s) :
Ryhänen, Jorma
Description :
Abstract
The shape memory effect, superelasticity, and good damping properties, uncommon in other implant alloys, make the nickel-titanium shape memory metal alloy (Nitinol or NiTi) a fascinating material for surgical applications. It provides a possibility to make self-locking, self-expanding and ...

Heart rate variability and baroreflex sensitivity in subjects without heart disease : effects of age, sex and cardiovascular risk factors
Author(s) :
Pikkujämsä, Sirkku
Description :
Abstract
Healthy subjects show wide interindividual variation in their
heart rate behavior, but the factors affecting heart rate dynamics
are not well known. This research was undertaken to evaluate heart
rate variability (HRV) and baroreflex sensitivity (BRS) in a large
random sample of subjec...

New heterodonor phosphine and bipyridine ligands
Author(s) :
Laitinen, Riitta
Description :
Abstract
Twenty-seven phosphine and six bipyridine ligands were synthesised and characterized. Additionally, a new route to the family of phosphine ligands via o-thioanisyldichlorophosphine was found. The phosphine ligands contain thiomethylphenyl, methoxyphenyl, dimethylaminophenyl, pyridyl, napht...

Otitis media in children : detection of effusion and influence on hearing
Author(s) :
Koivunen, Petri
Description :
Abstract
This study was undertaken to improve the diagnosis of otitis media and to investigate possible hearing loss caused by middle ear effusion (MEE) in small children.
The accuracy of minitympanometry in detecting MEE was evaluated in 162 children. The finding was compared with the amount of e...

Some applications of RF-gradients and excitation sculpting in NMR spectroscopy
Author(s) :
Heikkinen, Sami
Description :
Abstract
RF-gradients produced utilizing RF-field inhomogenity of conventional receiver/transmitter coil of NMR-probe can be used to mimic the effects of B0-gradients. This is done by placing long inhomogenous pulse in between two 90° pulses of appropriate phases (z-rotation cluster). B0-gradient b...

Kuronen, Timo
Description :
Alkusanat
Tietoverkkojen kehittyminen on lyhyessä ajassa muuttanut suuresti vakiintuneita atk:n käyttötapoja. Päätekäyttöiset keskuskoneet ovat jääneet lähes kokonaan pois käytöstä. Tilalle ovat tulleet mikrot,työasemat, palvelimet ja tietoliikenneverkot.
Tietoverkot ovat moninaisuudessaan vaikeit...
