Assessment of microalgae species, biomass, and distribution from spectral images using a convolution neural network
2022
AbstractEffective monitoring of microalgae growth is crucial for environmental observation, while the applications of this monitoring could also be expanded to commercial and research-focused microalgae cultivation. Currently, the distinctive optical properties of different microalgae groups are targeted for monitoring. Since different microalgae can grow together, their spectral signals are mixed with ambient properties, making estimations of species biomasses a challenging task. In this study, we cultured five different microalgae and monitored their growth with a mobile spectral imager in three separate experiments. We trained and validated a one-dimensional convolution neural network by…
Meaningful Work Protects Teachers’ Self-Rated Health under Stressors
2020
A sense of meaningfulness is one of the most sought?after work characteristics which has been associated with employees’ well-being. This study explored whether meaningful work enhances self-rated health in challenging work context, under the stressors of distractions, unnecessary tasks, and unreasonable tasks. Data was collected from Finnish teachers (N = 1,658) and structural equation modelling was employed with the latent interaction terms. Results showed that meaningful work was associated with better self-rated health and the stressors were associated with poorer self-rated health. Protective potential of meaningful work against stressors was also discovered, as meaningful work mitigat…

School of migrant children, an ethnography in an unregistered migrant school in Beijing
2012
This thesis discusses about the challenge of education for migrant children in the rapidly urbanized Chinese society. An ethnographic research was conducted in one of the unregistered migrant schools in Beijing. Through a triangulation of research methods of participatory observation, semi-structured and life history interview, as well as photography, the research, from emic perspectives, analyzes the advantages and disadvantages of the migrant schools in education provision to migrant children, understands the gaps between policy commitments and on-the-ground delivery of public education provision, and raises a few policy recommendations of developing the migrant schools and improving educ…
Microwave-assisted conversion of novel biomass materials into levulinic acid
2018
Levulinic acid is considered one of the most important platform chemicals. It is currently produced mainly from lignocellulosic biomasses. However, there are also other abundant biomass materials, which could be used as raw materials for levulinic acid production. In this work, levulinic acid was produced from two novel biomasses in the presence of Brønsted (H2SO4) and Lewis acid (CrCl3·6H2O or AlCl3·6H2O) catalysts. The studied materials were carbohydrate-rich potato peel waste and sporocarps of the fungus Cortinarius armillatus. Reaction conditions, i.e., time, temperature, H2SO4, and Lewis acid concentrations, were studied by utilizing full 24-factorial experimental designs. Microwave ir…
Minimalism for the Win : User-Centered Design for Guidance in Industrial Maintenance
2022
Background: We conducted an exploratory study to test the delivery of technical instructions built on the principles of minimalism. The aim was to investigate how we could support target users’ skill levels in a context-sensitive manner. Literature review: Related work examines minimalism, user needs and profiling, and industrial maintenance and technician experience. Research questions: 1. How can the semantic structure of DITA XML be utilized in delivering technical information to users based on their skill levels? 2. How would a layered system of information support the principles of minimalism? Methodology: We created material and tested the concept in user studies with maintenance pers…
