Hot smoke is always considered as the greatest threat during the early stages of evacuation in a building fire. As a result smoke control systems are required by most buildings regulations especially in high-rise buildings in Taiwan. The lobby is a temporary safe area for occupants’ evacuation and its smoke control system should offer high smoke prevention performance in the lobby area during evacuation.\nDifferent design scenarios are adopted in the study to simulate smoke conditions in the lobby area during occupants’ evacuation process in a building fire. The smoke control effect is significant affected by the opening or closing of the fire exit door. The diversity of smoke exhaust volumes and supply air volumes may offer different pressure scales and produce different smoke prevention results. When people take refuge together and the fire door cannot be closed, the minimum 10 Pa pressure difference in the lobby area is suggested to provide better smoke protection effect. Positive or negative pressure difference control depends on the fire door operational conditions.

A novel and effective methodology of non-rigid registration of a fluoroscopic coronary angiogram sequence using periodic displacement field is described. The proposed methodology is divided into two parts: extraction of per-frame displacement fields by non-rigid registration for frames comprising one heart cycle within a single sequence, and periodic registration of the remaining frames in the sequence using the extracted displacement fields. Using the proposed method, the motion of coronary vessels of an entire sequence is efficiently computed based on the estimated motion of one heart cycle. Experimental evaluation conducted on a set of 16 fluoroscopic angiograms resulted in reduced target registration error and computation time, demonstrating the robustness and efficiency of the proposed method.

s a result of the advancement of industries and technologies, the soil in Taiwan has suffered from serious heavy metal pollution at various levels caused by industrial waste substances and/or wastewater. The results show the addition of EDDS can effectively promote the heavy metal mobility, and increase the heavy metal absorption of plants; while the addition with GA3 can increase the biomass of plants and improve upward mobility of plants. Finally, the pot experiment indicates that adding EDDS and GA3 together can generate the best absorption efficacy in the soil containing Cu, Zn.\nThe pot experiment demonstrates the environmentally sustainable phytoremediation possesses optimal efficacy in remedying soil polluted by Cu, Zn, and the optimal method is adding EDDS and GA3 together. According to bacterial flora change result acquired from PCR and DGGE analysis, among the three groups, heavy metal+H20, heavy metal+GA3, and heavy metal+ EDDS+GA3, the last group has the richest bacterial flora. This demonstrates that when EDDS and GA3 are added together, the growth of microorganisms will be stimulated to create the richer development of bacterial flora.

Unfortunately, at any level of education, humane studies fall quite far from technical ones. The two fields even get farther from each other in the course of specialisation. However, in real life, multidisciplinary approach tends to gain more and more emphasis today. While the model curriculum of engineers contains 10% humane and economic studies (20 out of 210 ECTS), students in the faculty of liberal arts get no technical education during their 180 ECTS studies at all. The present article introduces the experiences of an innovative multidisciplinary course: ’Multimedia in Education’ as a subject for arts students. This article gives account on the curriculum, the educational experiences, as well as the opinion of the partaking students of the subject. A questionnaire was set up to measure students’ attitudes. Within the framework of the subject, the students acquire the technical approach to making a multimedia product at a basic level.
