Similarity Assessment of the Engineering Concepts: Decision‐Making Support and Metrics

open access: yesSystems Engineering, EarlyView.
ABSTRACT The new product development (NPD) process is a systematic approach to bring new products and innovations to market. Nowadays, this process is affected by a number of influencing factors associated with the fast‐paced technological changes. One of those factors is the distributed design nature of product development activities: team members are

The Quest for a Stable Disk

open access: yesThe Astrophysical Journal
The majority of disk galaxies manifest spirals and/or bars that are believed to result from dynamical instabilities. However, some galaxies have featureless disks, which are therefore inferred to be dynamically stable.

On the Structure of Galaxy Clusters

open access: yes, 2007
I summarise the state of the scientific exploration of the structure of galaxy clusters and present two new studies, namely, I propose and test a novel method to model clusters by a joint X-ray, thermal Sunyaev-Zeldovich and lensing analysis, and I investigate the impact of baryonic physics on strong cluster lensing and cluster structure.

Science Triggers and Situational Interest in Everyday Family Life

open access: yesJournal of Research in Science Teaching, EarlyView.
ABSTRACT Interest in science is critical for science learning. The family plays a major role in supporting the development of children's interest in science by eliciting and fostering interest and engagement with science content and practice. This study characterizes triggers for interest in science in everyday family life and measures the duration of ...

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK

open access: yesJournal of Research in Science Teaching, EarlyView.
ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).

The Effect of Seductive Details on Knowledge Retention in Physics Videos: A Mixed Methods Study

open access: yesJournal of Research in Science Teaching, EarlyView.
ABSTRACT Research reports that interesting but irrelevant information, seductive details, in teaching material can impede learning. In science education, the inclusion of historical narratives in lessons to promote interest has been recommended but may hinder learning.

Structure of Dark Matter in Galaxies [PDF]

open access: yes, 2004
The origin, nature and distribution of dark matter in the universe form some of the biggest questions in modern astrophysics. Dark matter is distributed on a wide range of scales in the universe. This thesis concentrates on galactic scales, attempting to lower the veil and probe the structure of dark matter in galaxies.
