The Study on the Carbon Reduction Measures Assessment of New Building Construction---Using Building Carbon Footprint Evaluation Method in Taiwan
Authors: Yang Shih-Hung , Jian You-Jhe 
Published: August 2019

Abstract
The study used the BCF system developed by LCBA to calculate the carbon footprint of the building’s life cycle. The case was the selection of a new educational building in Taipei, the first project in Taiwan to be required by government agencies to calculate carbon emissions. In addition to the calculation of carbon footprint, the purpose of this study is to assess the extent to which BCF tools can be used to feedback design contents before construction and to review the applicability of the tool itself. After BCFd’s life cycle carbon footprint assessment, it can be seen that the carbon footprint ratio in the use phase is as high as 80.41%, followed by 7.76% in the engineering material manufacturing phase. However, in the design feedback of BCFd, although specific material selection suggestions are proposed, the application of regulations, maintenance, durability, etc., must be discussed. Based on the actual use requirements of the owner, this study proposes a correction plan for the material selection, and the BCFd method evaluation proves that it also has the effect of reducing carbon.

Published: August 2019

Abstract
Thermal adaptive behaviors are the actions people take to adjust to the indoor environment. This study aims to clarify occupants’ perception of thermal environments and how they adapt themselves into those environments of air-conditioned offices in the tropical region. Six offices in Bangkok, Thailand, were investigated during April to September 2018. Indoor environment quality measuring devices were installed inside the offices to evaluate factors such as indoor temperature, humidity, and air velocity. Questionnaires following the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) 55 standard were distributed to occupants during working hours. Thermal comfort votes were analyzed together with behavioral adaptation votes. When we plotted thermal environment values on a psychrometric chart, they were inside 1.0 clo rather than 0.5 clo. Out of 2, 028 samples, 50.2 % of occupants voted neutral. However, they felt colder than neutral rather than feeling warmer than neutral (36 %:14 %). Occupants who felt comfortable were 45% of total occupants, and 59.7% of them preferred “no change”. Considering adaptive behavior, the highest activity was changing of clothes (50%). Those who wore more clothing (68.9 %) voted for feeling slightly cool to cold. Of those, 34% changed clothing during the day. The median of clothing increased from 0.56 clo to 0.61 clo to reduce the feeling-cold sensation and increase thermal neutrality. Other adaptive behaviors were drinking hot or cold water (31.3%), doing nothing (26.2%), moving around (24.5%), wearing a scarf (14.7%), using a pedestal fan (11.8%), taking a rest (8.6%), washing hands or face (8%), and opening or closing window blinds (7.7%). These adaptive behaviors were strongly relevant to thermal sensation votes and maintaining thermal comfort. These adaptive actions were adopted by both the feeling-hot persons and the feeling-cold persons. This study would be applicable to offices in Thailand in terms of both thermal satisfaction and human behavior.

Published: August 2019

Abstract
In order to study the influence of uniaxial compression test conditions on the strength and deformation characteristics of single-fractured similar rock with different penetration degrees, the author conducted the uniaxial compression test on prefabricated single-fractured similar rock using TAW-200 electronic multifunctional material mechanics testing machine. And quantitatively analysed the relationship between strength, elastic modulus and stress-strain of single fracture similar rock under uniaxial compression. The results show that the influence of uniaxial compression test on the peak strength is related to the penetration degree. The peak strength of specimens is the largest when there is no damage and the smallest when there is complete penetration (100%), but the peak strength of specimens not only decreases with the increase of penetration degree, but also relates to the crack dip angle. When the crack dip angle is different, the variation law of peak strength with penetration degree is also inconsistent; The influence of uniaxial compression test on elastic modulus is also related to penetration degree and crack dip angle, but the influence degree is different.

Published: August 2019

Abstract
The safety of the reservoir construction and the normal reservoir as well as the normal operation of the power station is affected by the phenomena of reservoir bank slopes’ instability and failure. Nowadays there is a lot of research about plain reservoir bank collapse, but the research about mountain valley reservoir bank collapse is not very perfect. Because of the various material characteristics and complex structure of mountain valley reservoir bank collapse, the influencing factors, mechanisms and types of mountain valley reservoir bank collapse is complex. According to a mountain valley reservoir site in southwest China, the bank collapse influencing factors are summarized, which are the formation lithology of the bank, the topography, the geologic structure, the hydrodynamic condition of the reservoir and the wave effect. The sensitivity of impact factors of the bank collapse is achieved by the orthogonal analysis. By contrast to single factor sensitivity, the cohesion in natural state and the wave height are the main impact factors.

Abstract
This work proposes a new method of diagnosing the variable torque pumping unit well, by analysing the eigenvalue of power-displacement diagram. Considering the actual angular velocity, the unbalanced weight of structure and the efficiency of motor and gearbox, the relationship between the polished rod load and the input power of motor are derived by analysing the internal relation between the polished rod load, the output shaft torque of the gearbox, the output shaft power of motor and the input power of motor. Then, the conversion model of the power-displacement diagram based on the dynamometer card is derived. By transforming the dynamometer card in typical working condition into the corresponding power-displacement diagram, 11 power-displacement diagrams in typical working conditions are established. By extracting the grayscale statistical eigenvalues from typical power-displacement diagrams, a working condition diagnosis model of oil well is established based on the grey correlation analysis. The test of 5 wells in the oilfield shows the average relative error of average normalized power of up and down stroke between the measured power-displacement diagram and the calculated power-displacement diagram are 6.31% and 5.83%, and the average fitting coefficient is 0.91. This shows that this model has a good accuracy, and it also proves the reliability of the typical power-displacement diagram. According to the test of 80 wells in the oilfield, the accuracy of diagnosis results based on the measured power-displacement diagram is 93.3%. This shows that the model has high accuracy and practicability, and can provide technical support for intelligent diagnosis and production optimization decision in production system of variable torque pumping unit well.

Authors: Luo Ping , Ren Chunwang , Kang Jian , Qing Zheng 
Published: August 2019

Abstract
The dark channel prior defogging algorithm is a method for rough estimation of transmittance. The dark channel prior method is not obvious enough for the sky. The paper uses a rough estimation model based on the relationship between depth of field and transmittance. A dehazing method that makes the transmittance more refined is proposed on a priori basis. The atmospheric light value is calculated from the atmospheric scattering model, and the image is converted from the RGB color space to the HSV color space and the S (saturation) component is extracted as a supplement to the transmittance. The final transmittance is obtained by the method of transmittance fusion, and a clear image is restored according to the atmospheric scattering model. The experimental results show that the method can effectively eliminate the fog, and the restored image better preserves the image details.

Authors: Yuan Dongyang , Zhan Wei 
Published: August 2019

Abstract
Engineering accidents often occurred in new tunnel construction because of the shallow burial tunnel with soft surrounding rock and large span. In this paper, the Three-step excavation method, ring excavation reservation method, CD method and double pilot tunnel method were compared by the numerical simulation method. The results show that: the settlement of the surface caused by the double pilot tunnel method is the smallest in the four excavation methods and the settlement of the surface can be effectively controlled by this method. The vault crown settlement and convergence deformation values by the double pilot tunnel method are the smallest in the four excavation methods. The stable condition of the surrounding rock by the double pilot tunnel method can be reached earlier than the other three methods. There are little differences in the stress of surrounding rock among the four excavation methods. However, the stress level of the support structure is different. The stress of the support structure by the double pilot tunnel is the smallest and it is less than the allowable tensile stress of shotcrete. Through the comparative analysis of various parameters, the double pilot tunnel method in the construction of shallow tunnel with soft rock and large span is recommended.

Published: August 2019

Abstract
In loess tableland area, farmers usually collected the soil in the surface of terrace section (or called “terrace wall”) as fertilizer. Actually it contains abundant nitrogen and potassium. As fertilizer, it would be used as new and ecological materials in crop production. In order to analyse the disciplinarian of soil nutrient in the surface of terrace wall, soil samples were divided into three different ages: one year, five years, above ten years; different two slope aspects: sunny- and shady slop; three ground level: 0.2m, 1m, 1.8m above ground; and three vertical depths: 0-1 cm, 1-5 cm, 5-10 cm. The results showed: with the increase of age and ground level, soil nutrients, such as total nitrogen, available phosphorus and potassium were activated and accumulated in the surface of terrace wall under the effect of solar-thermal resources. In the sunny slope, soil nutrients were much higher than those in the shady slope caused by radiation. Soil nutrients were decreased with the increase of sampling vertical depth, most soil nutrients were found in the section surface, which proved soil nutrients were mainly accumulated in the surface of terrace wall.

Authors: Wang Min 
Published: August 2019

Abstract
In the Daqing Oilfield, the oil flooding of one type of oil layer was transferred to the subsequent water flooding, and the third oil recovery object gradually transferred to the thinner and worse two or three oil layers. Although the three types of oil layers are thinner and have lower physical properties, their reserves are large, reaching 1.86 billion tons, accounting for 44.6% of the total reserves of the Lamadian Oilfield, Sarto Oilfield, Xingshugang Oilfield. It is the sustainable development potential of the oil fields after the second type of oil layers. Aiming at the characteristics of three types of oil layers, such as thin oil layer, poor physical property and scattered distribution, it is determined that it is suitable for polymer flooding to develop reservoir objects and their utilization limits. It is one of the difficult problems for the three types of oil layers to further improve oil recovery.

Published: August 2019

Abstract
It has concluded that the provenance of antimony ore in western Guizhou are as follows together with the previous researches: 1) the mineralization of antimony in western Guizhou is a long, complex process with different sources in various stages. 2) the main sources of antimony may differ in areas. Metallogenic material is provided for the formation of antimony by the “Dachang Layer” and “hydrothermal process”, the area overlapped by both is beneficial for forming antimony with high grade. 3) there may be some other factors providing the metallogenic material or participate in the formation of antimony, such as “oil-gas reservoir”, however, further researches are still needed.
