• A nonlinear mixed model approach to predict energy expenditure from heart rate 

  Kortelainen, Lauri; Helske, Jouni; Finni, Taija; Mehtätalo, Lauri; Tikkanen, Olli; Kärkkäinen, Salme (Institute of Physics, 2021)

  Objective: Heart rate (HR) monitoring provides a convenient and inexpensive way to predict energy expenditure (EE) during physical activity. However, there is a lot of variation among individuals in the EE-HR relationship, ...

• A Multi-Position Calibration Method for Consumer-Grade Accelerometers, Gyroscopes, and Magnetometers to Field Conditions 

  Särkkä, Olli; Nieminen, Tuukka; Suuriniemi, Saku; Kettunen, Lauri (Institute of Electrical and Electronics Engineers, 2017)

  This paper presents a calibration method for consumer-grade accelerometers, gyroscopes, and magnetometers. Considering the calibration of consumer-grade sensors, it is essential that no specialized equipment is required ...

• Calibration of the muon barrel chambers for the EMMA experiment 

  Sorjonen, Jukka (2017)

  The topic of this thesis was position calibration of muon barrel chambers used in the EMMA experiment. A detector ergo plank consist of seven chambers, and there were six uncalibrated detectors. The planks were set in a ...

• Remote Sensing of 3-D Geometry and Surface Moisture of a Peat Production Area Using Hyperspectral Frame Cameras in Visible to Short-Wave Infrared Spectral Ranges Onboard a Small Unmanned Airborne Vehicle (UAV) 

  Honkavaara, Eija; Eskelinen, Matti; Pölönen, Ilkka; Saari, Heikki; Ojanen, Harri; Mannila, Rami; Holmlund, Christer; Hakala, Teemu; Litkey, Paula; Rosnell, Tomi; Viljanen, Niko; Pulkkanen, Merja (Institute of Electrical and Electronics Engineers, 2016)

  Miniaturized hyperspectral imaging sensors are becoming available to small unmanned airborne vehicle (UAV) platforms. Imaging concepts based on frame format offer an attractive alternative to conventional hyperspectral ...

• Tietokonetomografian annosmittaukset : kalibrointikäytännöt ja epävarmuudet 

  Suutari, Juha (2015)

  Tietokonetomografiassa säteilyannoksen määrittämiseen käytettävät ionisaatiokammiot kalibroidaan tavallisimmin vapaasti ilmassa suhteessa ilmakermaan. Kalibrointikäytännöistä voi kuitenkin aiheutua epävarmuutta ...
