Abstract: In the green building concept, not only do the influences of the local climate, architectural form, usage mode, facilities condition, construction process, building materials and access management on the external environment as well as the comfortable and healthy internal environment are taken into account, but also the different interests of investors, users, design, installation, operation and maintenance personnel are integrated. In other words, the relationship among the lasting design, favorable environment and beneficiaries must be balanced and interactive, and hence the optimal greening effect can be accomplished. From this point of view, the green building can balance and coordinate the different needs and energy dependences between the internal and external environments and the users, and hence the buildings and the environments can be melted together naturally. In this paper, the author studies the whole process of integrating the "green building" into residence districts by the Yushan Huafu Home Community for example.

Abstract: Reservoir fluid sampling is the acquisition of subsurface fluid from within the wellbore at actual reservoir conditions using bottom hole sampling tools and techniques. Its main objective is to obtain some representative fluid sample of the reservoir to determine the PVT properties, reservoir potential, fluid type and composition needed for prompt field development campaigns. Experience have shown failure rates of fluid sampling in the Niger Delta is in the region of 20% or more, which result to the loss of vital well information and increased well cost especially in the small and medium fields, and some offshore drilling campaigns.

Abstract: Since Taiwan lacks self-produced energy, and is 98 percent reliant on imports for its primary energy. Increasing energy efficiency and energy savings are an essential part of Taiwan’s energy policy. This work summarized the energy saving potential of the Taiwanese textile industry from the on-line Energy Declare System in 2008. It was found that the total potential energy savings was thus 64,034 KL of crude oil equivalent (KLOE). The energy saving potential identified was 94,614MWh of electricity, 24,536 kiloliters of fuel oil, and 23,722 tons of fuel coal. It represented a reduction of 192,353 tons in carbon dioxide emissions.

Abstract: ISO 9223 can be used to categorize the corrosivity of atmospheres through either corrosion loss measurements or the use of environmental data. Although both methods are expected to give the same result, discrepancies have been found to occur. The present paper analyses this aspect of ISO 9223, focusing on the effects of metal composition, when using carbon steel, in corrosivity categorisation. Low and medium carbon steel were, therefore, exposed outdoors at one site in Mauritius to determine its atmospheric corrosivity. It was found that for medium carbon steel, the corrosivity obtained from corrosion loss results, through the weight loss method, was not in conformance with that obtained through the environmental data. This was not the case with low carbon steel. Taking into consideration the various factors affecting atmospheric corrosion, it was concluded that the carbon content of carbon steel is an important parameter that should be considered in ISO 9223 for more reliable determination of the corrosivity of atmospheres.

Abstract: Development of cities as well as population growth causes to development of public transportation especially subway lines. The high capacity besides the high speed in transportation makes them the popular transportation system. Fire is the one of the most important issues that may occur in subways. The difference in flame size, emissionheat, smoke and pollutants generation of subway fires attracts an especial attention of fire investigators. The emergency ventilation of subways in the case of fire should have the ability of discharging heat, smoke and pollutants from passenger escape route and preparing a safe place for a specific duration. The optimal performance of emergency ventilation system has a close relation with fire scenarios. In this research the fire scenarios of Tehran subway are designed based on regional approach. In order to show the performance of ventilation systems in emergency mode, the fire scenarios are simulated using computational fluid dynamics. Simulations are conducted for steady and unsteady modes. In transient simulations, a fast t2 growth curve is used for the heat and smoke release rate. Simulation results show that new regional scenarios could provide safe escape routes to evacuate passengers during the fire.

Abstract: In order to promote the yield of anticancer chemical compound PJ157 of marine YUP08 strain, the Linear Programming model (LP model) was used to optimize four components of medium for the strain. The primary culture medium consists of glucose, peptone, yeast and NaCl, which were possessory worked on growing and metabolism of the fungus. Contribution rate from data was built to manage complex effects for produce PJ157. It is forecast that the yield of PJ157 could be increased to 0.21735 mg/L which was great more than 0.04 mg/L in the before. Therefore the LP model could be used for fermentation optimization of microorganism.

Abstract: In order to know the environmental capacity, improve the continual deterioration of the water quality in Sushui River, and promote the harmonious development of economy and aquatic environment, we did the following research. Based on the 1-D steady-state water quality model, the outfalls are generalized, and then we derived the formula for calculating water environmental capacity of each reach. According to the information of water quality, hydrology data and the discharge distribution of the river, we chose COD, ammonia nitrogen and volatile phenol as the main control factors, and some formulas were used to calculate the water environmental capacity of COD, ammonia nitrogen and volatile phenol. From which we got that annual water environmental capacity of COD, ammonia nitrogen and volatile phenol on the studied reach respectively arrive at 1257.897~1420.928t, 17.873~26.025t and 1.750~2.871t under different design terms. It is serious pollution in the Sushui River, combined with the status quo emissions, we found that under different design terms, the annual quantity of pollutants reduction of COD, ammonia nitrogen and volatile phenol arrive at 30.36×106t, 3.257×106t and 0.1745×106t.

Abstract: In this paper,the protection schemes for phase-to-ground and multi-phase faults in micro-grids is proposed, accounting for the facts of new topology and operating characteristics of micro-grids.The definition of this protection schemes is to find solutions in a short term. For this reason the proposed solutions make use of traditional or commercially available protective switching and sensing devices, as well as automation techniques. Traditional technologies employed by this protection schemes can allow to find practical solutions to protect micro-grid feeders instead of a high number of inverted-interfaced generators resorting to different protection schemes ,and achieve minimum operating costs.

Abstract: According to characteristics of unidirectional flow of energy in permanent magnet wind power system, the paper proposes a two-quadrant three-level converter topology. Combined with method of the optimum tip speed ratio for tracking the maximum wind energy, the generator-side converter uses the double closed-loop control, speed outer loop and stator current inner loop control, whose control objective is to track the given generator speed. Grid-side converter uses the direct power control strategy based on virtual flux-linkage orientation. On the basis of MATLAB simulation platform, the permanent magnet wind power system simulation model was established. The simulation results show that the grid- and generator-side converter can operate with unity power factor, furthermore, verifies that the proposed converter structure is feasible.
