Title: Water Consumption of Potato (Solanum Tuberosum) Grown under Water Deficit Regulated with Mulched Drip Irrigation

Abstract: An experiment was conducted to determine the effect of mulched drip irrigation under water deficit on soil water content (SWC), stored soil water(SSW), daily water consumption(DWC) and ratio of water consumption in total water use (RWC) of potato in an arid area. Five water deficit treatments designed to subject potato to various levels of soil water deficit at different crop growth stages and a full irrigation control were established. The result indicated that the maximum SWC was at 20 cm depth in soil profile and that in 10 to 40 cm increment varied sharply during potato growing season. The SWC, SSW, DWC and RWC were significantly affected by mulched drip irrigation at water deficit regulation stages except at starch accumulation. Therefore, proper levels of soil water deficit regulated with mulched drip irrigation at proper plant growth stages could be used to regulate soil water status, stored soil water and crop water consumption effectively.

Title: Geotechnical Engineering Failure: Uncertainties or Ignorance

Abstract: Many failures in construction are related to geotechnical work. In most cases of geotechnical failures, it is anticipated that there are particular links between the failure and the prevailing geological and geotechnical aspects. From site investigation to design and constructions, the most uncertainties involve comes from geotechnical assessment. There are always uncertainties underneath the Earth surface that may or may not be revealed to the geotechnical engineer. Uncertainties that begins from soil parameters, analysis and assumptions which inevitably lead to the variations of results and conclusions. Generally the main cause of failure could be from various sources such as underestimation of loading and strength parameters, lack of geotechnical knowledge, simple error that cause large effect on the system and finally financial commitment. The core of the risk often came from financial commitment where in many cases when a lack of time, money will lead the managers to take unacceptable known or unknown risks. When any geotechnical failure occurs, related experts will assign its cause to an event that immediately precedes the failure, such as an earthquake, heavy rainfall, flood, or other natural event. However, this normally lead to wrong conclusions. Failures normally occurs due to the acceptable of marginally stable conditions resulted from substandard investigations by the technical personnel, improper design, and inadequate review by the permitting agency. Statistically it shows that most of the failure are repetitive event. It could be avoided if related personnel seriously consider lesson learn from previous geotechnical failure. In Malaysia almost 80% of failure is due to settlement while the rest is due to bearing failure, vibration, water infiltration, slope failures and many more. Even though settlement has been address as a common failure and geotechnical processes themselves are becoming better controlled and more reliable, failures continue to arise with embarrassing frequency. This keynote will address the cause of geotechnical failure base on case study from Malaysia experience. A number of case histories will be reviewed here to try to distinguish the main risk factors that must receive attention if a reduction in geotechnical failures is to be achieved.

Title: A theoretical framework for atmosphere-building-soil energy flow systems

Abstract: Lack of concern for spatial variation of urban soil temperature does not reflect the importance of soil temperature in ecosystem service. The method of construction-soil micro gradient transects (CSMGT) and in situ observations were applied in this study to understand the mechanism of higher soil temperatures in urban areas and the spatial variation of the temperature of surface soil layer adjacent to constructions. Based on experimental data, a new theoretical framework for atmosphere-building-soil energy flow systems was established to analyse the changing rate of the temperature of surface soil layer (RS) adjacent to constructions. The results of redundancy analysis and hierarchical partitioning showed horizontal heat flux between building and soil (HHF0) played a very important role in driving RS along the CSMGT at night, whereas joint effects of multiple energy factors drove it during daytime or on the scale of an entire day.

Title: The Research of English Vernacular Architecture History since 16th Century to Mid-20th Century

Abstract: As an important material carrier of rural landscape, English vernacular architecture has experienced five periods of germination, sample textual research, discipline establishment, academic formation and multi-dimensional vision since the 16th century, which has affected the residential architecture morphology in the same period accordingly. The research shows that the study of vernacular architecture follows the process from the narrow sense of physical architecture morphology to the broad sense of conceptual housing morphology, and the academic accumulation stage before World War II laid the foundation for the diversification of follow-up research. From the perspective of research methodology and academic problem domain, this paper re-summarizes the connotation of English vernacular architecture and sorts out the theme of the times, the main thread of logic and the academic influence of each stage before the middle of the 20th century. The academic direction and research methods of Chinese vernacular architecture are also discussed in this paper.

Title: A study for Application Research of "Regional" Architectural Culture in Architectural Design Courses

Abstract: Under the impact of the globalization culture, the city's style looks like the same in many cities in China. It has caused the reflection of the architects and hopes to integrate regional culture into the architectural design. This article takes the design topic “Pedestrian Commercial Street Design” in architectural design teaching as an example. By comparing the learning effects of students before and after study, it provides practice and reflection for regional architecture design. Firstly, it reviews and discusses the development of Yinchuan regional architecture and regional theory as the basis of teaching process. Secondly, through the practical operation of design teaching, students are guided to complete relevant design content. Finally, through the questionnaire survey on the learning effect before and after the students' study, the students' regional academic operation results are summarized. By reflecting on the concept of regional architecture in the process of design teaching, the author tries to put forward some suggestions on the development of regional architecture.
