Researcher of the month is Samuli Siltanen
1 October, 2010 - 13:14
Samuli Siltanen is currently in the Inverse problems research group at University of Helsinki. He is a researcher in the modeling and measurements/ QVision theme, which belongs to the research program EffTech (Intelligent, resource-efficient production technologies) of the Forestcluster Ltd. In 1999, Samuli got his PhD from Helsinki University of Technology.
QVision project focuses on image-based measurement methods for quality in pulping and papermaking. This project develops methods such that the functional properties of fiber-based products can be developed, and also managed in production, at a radically improved degree of specificity and scope. The methods are a necessity in the development and production of new high added-value products.
The goal of Samuli's research is to develop inversion methods with the help of fiber product X-ray pictures can sort out product's functional features. The main goal is to calculate from X-ray pictures important information such as weightiness, firmness and fiber orientation for manufacturer. The aim is to move from offline pictures to online pictures and produce real time quality information.
The successfully developed method can be transferred to other purpose of use because of universal applicability of mathematics.
The benefit from this type of research is faster and more accurate quality control. This type of research method is also cost efficient and environmental friendly.
The best thing working at such a large project is to get to know all other experts in this research area. The benefits for Samuli to work in this kind of EffTech program are networking and co-operation.
When not working, Samuli spends time, for example, photographing spiders and training with kettlebells.
