Both conservation and intervention methods must be compatible with each other and appropriate for the original building materials. Therefore, the characterization of historic building materials is indispensable for investigating chemical composition, micro-structure and morphological features to study the current condition, environmental influence and change mechanism due to natural aging or man-made...
In this paper, we study the effect of B introduction in various Heusler alloys on their structural and magnetic properties. Samples with nominal stoichiometry Fe50+xCu25−xGa25, Fe50+xCu25−xAl25, and Fe50+xCo25−xGa25(x= 0–10) with the addition of excess B up to 12 at% were prepared with Ar arc-melting as base materials. The starting materials were subsequently converted to ribbons using melt-spinning...
EMI engineers are struggling everyday with complex radiation problems that fails critical products to pass EMI certification and causes big loss of profit. Advances in EMI engineering are following a similar trend like Signal-Integrity engineering 10-years ago when tools nowadays became capable of providing accurate predictive simulations in a reasonable amount of time. With careful engineering utilizing...
Magnetically controlled shape memory alloy (MSMA) changes its shape with the magnetic field, it can also be used in the inverse operation as sensors. Based on inverse characteristics of MSMA material, prototype and experimental system of the vibration sensor is designed and developed. The operation principle of MSMA vibration sensor is analyzed, the variation laws of induced voltage peak-peak are...

Blended courses that include face-to-face and e-learning have been offered in universities in Taiwan but very little research has been undertaken on university student perspectives of effective e-learning strategies. This paper explores student perceptions of effective e-learning strategies their instructors used in blended courses in a national research-oriented university in Taiwan. An interpretive...
E-learning has altered, and will continue to affect teaching and learning contexts in tertiary education but very little research has been undertaken on university instructor perspectives of technology use in e-learning teaching. This paper explores the perceived benefits of technology use in e-learning by university instructors in Taiwan. These perceived benefits included benefits for the university,...
Magnetic shape memory (MSM) material is a class of smart material that changes shape when it is exposed to a moderate magnetic field, which provides a new way to produce motion and force. The material has also another interesting property: the MSM material can change its magnetic property when it is subjected to external force, which is known as sensing characteristics of MSM material. In this paper,...
