It was applied in a study case. The interactive application allows the examination of the physical model, visualizing, for each element modeled in three-dimensions （3D） and linked to a database, the corresponding technical information concerned with the use of the material, calculated for different points in time during their life. The control of a lamp stock, the constant updating of lifetime information and the planning of periodical local inspections are attended on the prototype. This is an important mean of cooperation between collaborators involved in the building management.展开更多

It is the first time such sensors were used for soil suction measurement. They are microfabricated relative humidity sensors (footprint area 11,000 μm × 22,000 μm) operating based on changes in electrical resistivity detected by a cerium doped silica titania film deposited using a sol-gel technique. Their design required gathering experts in several engineering specialties. The working principle of the sensors is based on water vapour equilibrium between the air in the soil and in the sol-gel pores, due to the contact between the two porous materials. The spacing between interdigitated aluminium electrodes was optimized to improve the sensing properties of the sol-gel. The calibration of the different prototypes was done against compacted clay, varying the spacing between 100 and 700 μm. The sensors were also incorporated in soil samples for suction measurement during wetting and drying paths. They were validated by comparing the readings with those from a water dew point potentiometer. From this study it was possible to determine the optimum electrodes spacing of 200 μm. Error was explained by sol-gel heterogeneity effect and by the resolution of the sensing area provided by the electrodes spacing. When comparing with other sensors operating inside soil specimens in standard laboratorial tests, these sol-gel sensors extend the operation range available with the alternative technologies: while conventional tensiometers measure suction ranges from 0 to 1.8 MPa, our sensors demonstrate good results between 1 to 10 MPa (and higher).展开更多

Interpersonat interactions have a key rote during the processes of design and critique. The influence of emotional intelligence （EQ） on interpersonal communication skirts has been widely proven. This study examines the correlation between EQ and architecturat design competence, To achieve this, 78 architecture students were setected via a simple random sampling method and tested using an EO. test questionnaire developed by Bradbury and Greaves （2006）. The scores of five architectural design studio courses （ADS-1, ADS-2, ADS-3, ADS-4, and ADS-5） were used as indicators of the progress in design of the students.
