Recent advances in machine learning for maximal oxygen uptake (VO2 max) prediction : A review
2022
Maximal oxygen uptake (VO2 max) is the maximum amount of oxygen attainable by a person during exercise. VO2 max is used in different domains including sports and medical sciences and is usually measured during an incremental treadmill or cycle ergometer test. The drawback of directly measuring VO2 max using the maximal test is that it is expensive and requires a fixed and controlled protocol. During the last decade, various machine learning models have been developed for VO2 max prediction and numerous studies have attempted to predict VO2 max using data from submaximal and non-exercise tests. This article gives an overview of the machine learning models developed over the past five years (…
A New Fitness Test of Estimating VO2max in Well-Trained Rowing Athletes
2021
BackgroundThis study was designed to investigate the validity of maximal oxygen consumption (VO2max) estimation through the Firstbeat fitness test (FFT) method when using submaximal rowing and running programs for well-trained athletes.MethodsWell-trained flatwater rowers (n = 45, 19.8 ± 3.0 years, 184 ± 8.7 cm, 76 ± 12.9 kg, and 58.7 ± 6.0 mL⋅kg–1⋅min–1) and paddlers (n = 45, 19.0 ± 2.5 years, 180 ± 7.7 cm, 74 ± 9.4 kg, and 59.9 ± 4.8 mL⋅kg–1⋅min–1) completed the FFT and maximal graded exercise test (GXT) programs of rowing and running, respectively. The estimated VO2max was calculated using the FFT system, and the measured VO2max was obtained from the GXT programs. Differences between the…

Versailles project on advanced materials and standards (VAMAS) interlaboratory study on measuring the number concentration of colloidal gold nanopart…
2022
The advancement of analytical methods for nanoparticle measurements is critical both for the growing industrial exploitation of engineered nanoparticles and for developing robust strategies to understand and control the concentration of nanomaterials in humans and the environment. For high value nanoparticles, the measurement of nanoparticle number concentration in a liquid directly impacts the ability to assess the scale and reproducibility of the production process, it allows optimisation of efficiency and supports regulatory compliance. This measurement is also useful to monitor and control the intentional or accidental release of engineered nanoparticles into the environment at the produc…
Biogas measurement techniques and the associated errors
2011
There are several techniques for the measurement of laboratory scale biogas production. This thesis describes the study and evaluation of the most significant and commonly used biogas measurement techniques and analyzes the source of errors associated with the measurement of biogas production. Firstly, inaccuracy mainly due to biogas carbon dioxide (CO₂) dilution in displaceable liquids and losses to atmosphere of dissolved CO₂ was evaluated by testing solubility of CO₂ in different barrier solutions. Saturated acidified brine solution showed lower CO₂ solubility among the tested solutions. An accurate, simple, automated and easy to calibrate laboratory scale liquid displacement gas measuri…

Electron spectroscopy with the SAGE spectrometer
2016
A device called the SAGE (Silicon And GErmanium) spectrometer, designed for in-beam electron spectroscopy, is introduced in this work. A detailed description to the technical aspects of the device is given along with several examples of analytical procedures related to work done with the device. The radial ltering method and veto/add-back algorithms are tools for improving the quality of the electron-gamma data whilst the time-gate selection procedure helps in determining absolute internal conversion coe cients without reference points. Two very di erent types of experiments with results obtained from the electron data are introduced and analysed. Coulomb excitation is used to probe 154Sm a…
Lukemisen ja aritmetiikan sujuvuuden kehittyminen toisen koululuokan aikana
2014
Tutkimuksessa tarkasteltiin lukemisen ja aritmetiikan sujuvuutta ja niiden kehitystä toisen koululuokan aikana kolmena ajankohtana (lukukauden alussa, keskellä ja lopussa). Lukemisen sujuvuuden kehitys oli edistyvää niin sujuvilla kuin sujumattomillakin lukijoilla. Sen sijaan yhteen- ja vähennyslaskutaidon sujuvuudessa ei tapahtunut juurikaan kehitystä sujumattomilla laskijoilla, toisin kuin sujuvilla laskijoilla, joiden kehitys oli edistyvää lukukauden aikana. Tulokset tukevat oletusta aritmetiikan taitojen kehityksen Matteusvaikutuksesta, eli siitä, että lähtötasoltaan aritmetiikassa sujumattomien kehitys jää jälkeen lähtötasoltaan sujuvien laskijoiden kehityksestä. Lukutaidon taso ei sen…
