A schematic to make the spectra of the exterior noise of high speed railway was put forward. The exterior noise spectrum was defined based on the characteristics of the high-speed train exterior noise. Its characteristics considered here include identifying the exterior main sources and their locations, their frequency components including the Doppler effect due to the noise sources moving at high speed, the sound field intensity around the train in high-speed operation, the sound radiation path out of the train, and the pressure level and frequency components of the noise at the measuring points specified by the International Organization for Standardization(ISO). The characteristics of the high-speed train exterior noise of the high speed railways in operation were introduced. The advanced measuring systems and their principles for clearly indentifying the exterior noise sources were discussed in detail. Based on the concerned noise results measured at sites, a prediction model was developed to calculate the sound level and the characteristics of the exterior noise at any point where it is difficult to measure and to help to make the exterior noise spectrums. This model was also verified with the test results. The verification shows that there is a good agreement between the theoretical and experimental results. 展开更多

The contamination diffusion to the operating room when the door is open was simulated with a computational fluid dynamic(CFD) method,to give the extent of the contamination diffusion.The influence of the door-opening procedure was ignored since the door of the operating room is normally a sliding one.The flow field in the case of the 16 s course of opening the door was simulated.The simulated and the experimental results demonstrate that the extent of the contamination diffusion is around 1.5 m when there is no temperature difference between indoor and outdoor,and there is hardly any contamination diffusion when the temperature difference is 1 ℃.It can be concluded that the positive pressure difference in the operating room lost its function in preventing the contamination when the door is open.That the temperature of corridor is lower than that of operating room contributes to contamination control.Keeping 1 ℃ temperature difference between corridor and operating room and increasing positive pressure and air flow are suggested.It is more secure to set up an anteroom if persons come in or out of the operation room at the course of surgery. 展开更多

The micro-turbine is known as a producer of high-grade energy (work) and also low energy (heat). The following low grade heat energy have been modeled under ISO ambient conditions (international standard organization), i.e. 15 ℃ and 1 bar, to utilize the waste heat energy of a 200 kW micro-turbine combined with a single effect absorption chiller, an organic ranking cycle using R245fa (ORC-R245 fa) as a working fluid, a multi-effect distillation desalination (MED) and a thermal vapor compression MED Desalination unit (TVC-MED). The thermal comparison was carried out based on an energy and exergy analysis in terms of electric efficiency, exergetic efficiency, carbon footprint, and energy utilization factor (EUF). The software package IPSEpro has been used to model and simulate the proposed power plants. As a result, utilizing the exhaust waste heat energy in single-effect absorption chillier has contributed to stabilize ambient temperature fluctuation, and gain the best exergetic efficiency of 39%, while the EUF has reached 72% and the carbon footprint was reduced by 75% in MED and TVC-MED Desalination respectively. The results also reveal that TVC-MED is more efficient than traditional MED as its gain output ratio (GOR) is improved by 5.5%. In addition, ORC-245fa generates an additional 20% of the micro-turbine electricity generation. 展开更多

Reliable service life data of building products are of great importance when completing environmental LCA (life cycle assessment) reviews, for LCC (life cycle costing) and for maintenance planning tasks. A research project was set up to answer the following research questions: (1) what are reliable service life data of current used building products; and (2) how can generic data about the service lives of building products be tailored to specific project circumstances using the "factor method" described in the ISO (International Standard Organization) 15686 Series: "Buildings and Constructed Assets-Service-Life Planning". Experts of industry organisations for building materials and products made a final judgement of the new established reference service lives. Reference service lives of building products may show a large unknown bandwidth around the average. That will make the bandwidth of estimated service lives, taking the project situation of building components into account, very big. Experts have raised objections to the use the factor method for deriving mathematically a bandwidth of estimated service lives of a building product from the reference service life of the product. A practical analytical application of the factor method has been made by describing all factors and underlying criteria and a reference situation. 展开更多

IDE-OTALEX is the first crossborder spatial data infrastructure between contiguous Portuguese (Alentejo and Centro) and Spanish (Extremadura) regions. It was implemented to share official geographic information from Alentejo and Extremadura, and now Centro region, with everyone. This is the most effective way to have a distributed and flexible system to be used as a territorial observatory for sustainable development and environment protection in these rural and low populated regions. It also contributes to territorial cohesion, one of the tree main pillars of European Cohesion Policy. It's characterized for being a distributed, decentralized, modular and collaborative system, based on standards OGC (Open Geospatial Consortium), W3C (World Wide Web Consortium), ISO (International Organization for Standardization) and open source technology, developed to guarantee interoperability between the different GIS (Geographic Information System) provided by each project partner. The geoportal is multilingual (Portuguese, Spanish and English) and integrates a Map viewer, Metadata Catalogue and Gazetteer. It consists in central and local nodes which communicate through WMS (Web Map Services), CSW (Catalogue Service Web) and WFS (Web Feature Services). It is now implementing SOS (Sensor Observation Services) and WPS (Web Map Processing). The geographic information available results of an extensive work of data harmonisation adapted to INSPIRE Directive (D 2007/2/EC, the European Parliament and Council, March 14, 2007). It integrates basic cartography, socio-economic, territorial and environmental indicators. 展开更多

Objective This study proposes to visually review the current situation and progress of standards sets by the International Organization for Standardization/Technical Committee on Traditional Chinese Medicine(ISO/TC 249). The review aims to explore the development strategies of the standards, which will exhibit the considerable impact on the economy, trade and exchanges, and cooperation in the area of traditional Chinese medicine(TCM).Methods ISO/TC 249 standards were searched on the ISO website, and their title, proposed time, current stage, scope, and classification were obtained for further summarization. Gephi was utilized to portray the co-occurrence network graph of the ISO/TC 249 standards subject.Results In ISO/TC 249, there were 116 standards, including 81 published standards and 35 developing standards by April 30, 2022. Two withdrawal standards were published after revision, which were not counted in the total standards. The number of published standards has been increasing since the first standard was published in 2014, whose title was “Sterile acupuncture needles for single use”. Among these standards, 17.24%(20/116) standards were in review, 56.03%(65/116) in publication, 3.45%(4/116) in approval, 5.17%(6/116) in enquiry,3.45%(4/116) in committee, and 14.66%(17/116) in preparation, respectively. With 116 standards, most of the research focused on the medicament, as its classification of the International Classification for Standards(ICS) showed the proportion reaching 49.54%. The network analysis data revealed that the top five most frequent words were “materials” “root” “requirements” “products” and “system”, after removing the noise data, such as prepositions,conjunctions, and pronouns. Additionally, the word “system” co-exists with the terms “computerized” “coding” “image” “tongue” and “analysis”;the word “requirement” co-exists with“manufacturing” “decoction” “process” and “materials”;whereas the word “devices” coexists with “pulse” “electric” “skin” and “measurement”.Conclusion With the increased diversification and complexity of problems, the development of standards is also oriented to multidisciplinary fields to cultivate the interdisciplinary talents, and especially the international standardization talents of compound TCM. Multi-angle analysis, formulation, and demonstration of standards, in line with industry needs in different disciplines, enhance the availability of standards and the ability to serve the industry. 展开更多

BIM should be used for this. Building Information Modellingis a collaborative process where all stakeholders integrate and optimize their information in a digital 3D model. Sometimes it is called Green BIM. But what exactly is that? Is the International Standard Organization IFC standard useful for this? And is it compatible with new developments in parametric design? Advantages and disadvantages of BIM are listed. Full parametric design is needed because it keeps the design flexible and open for changes until the end of the design process. However it is not compatible with IFC; only object parametric design is. A possible way out of this paradox could be the use of scripts that only create objects if they are not already in the BIM database and otherwise only adapt their properties. An example of parametric sustainable architectural design explains the mentioned issues. 展开更多

The purpose of this paper is to investigate reasonable cost benefit criteria within the framework of environmental formal safety assessment (FSA). In this study a statistical analysis of oil spill data was carried out based on the report of International Oil Pollution Compensation Funds. According to the statistical study of actual oil spill from tankers, it is found that collisions and groundings are the most probable causes of the oil spills from tankers. Probability distributions of costs of oil spill and oil spill amount are investigated, and a non-linear regression formula between costs of oil spills and oil spill weight are derived. Using the regression formula, an oil spill weight dependent CATStm (Cost of Averting a Ton of oil Spilt) is proposed. Moreover in order to apply the weight dependent CATSthr to cost benefit analysis (CBA), a new cost-effective criterion is newly proposed with considering its concrete application to environmental FSA. 展开更多

OBJECTIVE: To supply literature for developing an international standard of auricular acupuncture points. METHODS: Electronic database searches were con- ducted in the Chinese National Knowledge Infra- structure and VlP, and the Western databases, Pubmed, the National Science and Technology Li- brary, and the German Journal of Acupuncture, from 1990 to April, 2012. We also searched the doc- uments of international symposiums for auricular acupuncture points (AAPs). Keywords were "auricu- lar points", "auricular acupuncture points", "ear points", or "auriculotherapy" RESULTS: Basic and clinical research on AAPs was performed in China, the United States, France, andGermany. Clinical AAP research was done in Italy, Austria, Switzerland, Spain, the UK, Holland, Japan, Russia, and Africa. However, AAP research was not communicated internationally. The World Federa- tion of Acupuncture-Moxibustion Societies recom- mended international standard of auricular acu- puncture points (ISAAPs). Standardized nomencla- ture and locations of AAPs would provide a solid basis to draft an international standard organiza- tion. CONCLUSION: Experts need to find common points from different countries or regions, provide evidence of different ideas, and list the proposal as a recommendation for an international standard. 展开更多

Temporal variation of dynamical modal properties of a base-isolated building is investigated using earthquake records in the building. A batch processing least-squares estimation method is applied to segment-wise time-series data. To construct an input-output system,an auto-regressive model with exogenous input (ARX) of second-order including a forgetting coefficient as a weighting coefficient is used for the estimation of modal parameters. The fundamental and second natural frequencies and the damping ratios of the fundamental and second natural modes of the base-isolated building are identified in the time domain. The identified results are consistent with the results obtained from the micro-tremor vibration data,forced-vibration test data and earthquake records in the present base-isolated building in the case of taking into account the amplitude-dependency of the isolators and viscous dampers. It is finally pointed out that several factors,e.g.,amplitude dependency of the isolator and damper system and special characteristics of the series-type viscous damper system,may be related complicatedly with the temporal variation in modal properties of the above-mentioned system. 展开更多
