We provide insights into the performance of surv eyed firms across key components of working capital management by usi ng the CFO magazine’s annual Working CapitalManagement Survey. We discover that significant differences exist b etween industries in working capital measures across time.In addition.w e discover that these measures for working capital change significantl y within industries across time.IntroductionThe importance of efficient working capital management is indisputa ble. Working capital is the difference between resources in cash or readily convertible into cash (Current Assets) and organizational commi tments for which cash will soon be required (Current Liabilities). Th e objective of working capital management is to maintain the optimum balance of each of the working capital components. Business viabilit y relies on the ability to effectively manage receivables. inventory.a nd payables. Firms are able to reduce financing costs and/or increase the funds available for expansion by minimizing the amount of funds tied up in current assets. Much managerial effort is expended in b ringing non-optimal levels of current assets and liabilities back towa rd optimal levels. An optimal level would be one in which a balance is achieved between risk and efficiency.A recent example of business attempting to maximize working capita l management is the recurrent attention being given to the applicatio n of Six Sigma®methodology. Six S igma®methodologies help companies measure and ensure quality in all areas of the enterprise. When used to identify and rectify discrepancies.inefficiencies and erroneous tra nsactions in the financial supply chain. Six Sigma®reduces Days Sale s Outstanding (DSO).accelerates the payment cycle.improves customer sati sfaction and reduces the necessary amount and cost of working capital needs. There appear to be many success stories including Jennifertwon’s(2002) report of a 15percent decrease in days that sales are outstanding.resulting in an increased cash flow of approximately $2 million at Thibodaux Regional Medical Cenrer.Furthermore bad debts declined from 3.4millin to $6000000.However.Waxer’s(2003)study of multiple firms employing Six Sig ma®finds that it is really a “get rich slow”technique with a r ate of return hovering in the 1.2 – 4.5 percent range.Even in a business using Six Sigma®methodology. an “optimal”level of working capital management needs to be identified. Industry factors may impa ct firm credit policy.inventory management.and bill-paying activities. S ome firms may be better suited to minimize receivables and inventory. while others maximize payables. Another aspect of “optimal”is the extent to which poor financial results can be tied to sub-optimal pe rformance.Fortunately.these issues are testable with data published by CFO magazine. which claims to be the source of “tools and informati on for the financial executive.”and are the subject of this resear ch.In addition to providing mean and variance values for the working capital measures and the overall metric.two issues will be addressed in this research. One research question is. “are firms within a p articular industry clustered together at consistent levels of working capital measures?For instance.are firms in one industry able to quickl y transfer sales into cash.while firms from another industry tend to have high sales levels for the particular level of inventory . The other research question is. “does working capital management perform ance for firms within a given industry change from year-to-year?”The following section presents a brief literature review.Next.the r esearch method is described.including some information about the annual Working Capital Management Survey published by CFO magazine. Findings are then presented and conclusions are drawn.Related LiteratureThe importance of working capital management is not new to the f inance literature. Over twenty years ago. Largay and Stickney (1980) reported that the then-recent bankruptcy of W.T. Grant. a nationwide chain of department stores.should have been anticipated because the co rporation had been running a deficit cash flow from operations for e ight of the last ten years of its corporate life.As part of a stud y of the Fortune 500s financial management practices. Gilbert and Rei chert (1995) find that accounts receivable management models are used in 59 percent of these firms to improve working capital projects.wh ile inventory management models were used in 60 percent of the compa nies.More recently. Farragher. Kleiman and Sahu (1999) find that 55 p ercent of firms in the S&P Industrial index complete some form of a cash flow assessment. but did not present insights regarding account s receivable and inventory management. or the variations of any curre nt asset accounts or liability accounts across industries.Thus.mixed ev idence exists concerning the use of working capital management techniq ues.Theoretical determination of optimal trade credit limits are the s ubject of many articles over the years (e.g. Schwartz 1974; Scherr 1 996).with scant attention paid to actual accounts receivable management.Across a limited sample. Weinraub and Visscher (1998) observe a tend ency of firms with low levels of current ratios to also have low l evels of current liabilities. Simultaneously investigating accounts rece ivable and payable issues.Hill. Sartoris.and Ferguson (1984) find diffe rences in the way payment dates are defined. Payees define the date of payment as the date payment is received.while payors view paymen t as the postmark date.Additional WCM insight across firms.industries.a nd time can add to this body of research.Maness and Zietlow (2002. 51. 496) presents two models of value creation that incorporate effective short-term financial management acti vities.However.these models are generic models and do not consider uni que firm or industry influences. Maness and Zietlow discuss industry influences in a short paragraph that includes the observation that. “An industry a company is located in may have more influence on th at company’s fortunes than overall GNP”(2002. 507).In fact. a car eful review of this 627-page textbook finds only sporadic information on actual firm levels of WCM dimensions.virtually nothing on industr y factors except for some boxed items with titles such as. “Should a Retailer Offer an In-House Credit Card”(128) and nothing on WC M stability over time. This research will attempt to fill this void by investigating patterns related to working capital measures within industries and illustrate differences between industries across time.An extensive survey of library and Internet resources provided ver y few recent reports about working capital management. The most relev ant set of articles was Weisel and Bradley’s (2003) article on cash flow management and one of inventory control as a result of effect ive supply chain management by Hadley (2004).Research Method The CFO RankingsThe first annual CFO Working Capital Survey. a joint project with REL Consultancy Group.was published in the June 1997 issue of CFO (Mintz and Lezere 1997). REL is a London. England-based management co nsulting firm specializing in working capital issues for its global l ist of clients. The original survey reports several working capital b enchmarks for public companies using data for 1996. Each company is ranked against its peers and also against the entire field of 1.000 companies. REL continues to update the original information on an a nnual basis.REL uses the “cash flow from operations”value located on firm cash flow statements to estimate cash conversion efficiency (CCE). T his value indicates how well a company transforms revenues into cash flow. A “days of working capital”(DWC) value is based on the d ollar amount in each of the aggregate.equally-weighted receivables.inven tory.and payables accounts. The “days of working capital”(DNC) repr esents the time period between purchase of inventory on acccount fromvendor until the sale to the customer.the collection of the receiva bles. and payment receipt.Thus.it reflects the companys ability to fin ance its core operations with vendor credit. A detailed investigation of WCM is possible because CFO also provides firm and industry val ues for days sales outstanding (A/R).inventory turnover.and days payabl es outstanding (A/P).Research FindingsAverage and Annual Working Capital Management Performance Working capital management component definitions and average values for the entire 1996 –2000 period .Across the nearly 1.000 firms in the survey.cash flow from operations. defined as cash flow from operations divided by sales and referred to as “cash conversion ef ficiency”(CCE).averages 9.0 percent.Incorporating a 95 percent confide nce interval. CCE ranges from 5.6 percent to 12.4 percent. The days working capital (DWC). defined as the sum of receivables and invent ories less payables divided by daily sales.averages 51.8 days and is very similar to the days that sales are outstanding (50.6).because the inventory turnover rate (once every 32.0 days) is similar to the number of days that payables are outstanding (32.4 days).In all ins tances.the standard deviation is relatively small.suggesting that these working capital management variables are consistent across CFO report s.Industry Rankings on Overall Working Capital Management Perfo rmanceCFO magazine provides an overall working capital ranking for firms in its ing the following equation:Industry-based differences in overall working capital management are presented for the twenty-s ix industries that had at least eight companies included in the rank ings each year.In the typical year. CFO magazine ranks 970 companies during this period. Industries are listed in order of the mean ove rall CFO ranking of working capital performance. Since the best avera ge ranking possible for an eight-company industry is 4.5 (this assume s that the eight companies are ranked one through eight for the ent ire survey). it is quite obvious that all firms in the petroleum in dustry must have been receiving very high overall working capital man agement rankings.In fact.the petroleum industry is ranked first in CCE and third in DWC (as illustrated in Table 5 and discussed later i n this paper).Furthermore.the petroleum industry had the lowest standar d deviation of working capital rankings and range of working capital rankings. The only other industry with a mean overall ranking less than 100 was the Electric & Gas Utility industry.which ranked secon d in CCE and fourth in DWC. The two industries with the worst work ing capital rankings were Textiles and Apparel. Textiles rank twenty-s econd in CCE and twenty-sixth in DWC. The apparel industry ranks twenty-third and twenty-fourth in the two working capital measures ConclusionsThe research presented here is based on the annual ratings of wo rking capital management published in CFO magazine. Our findings indic ate a consistency in how industries “stack up”against each other over time with respect to the working capital measures.However.the wor king capital measures themselves are not static (i.e.. averages of wo rking capital measures across all firms change annually); our results indicate significant movements across our entire sample over time. O ur findings are important because they provide insight to working cap ital performance across time. and on working capital management across industries. These changes may be in explained in part by macroecono mic factors Changes in interest rates.rate of innovation.and competitio n are likely to impact working capital management. As interest rates rise.there would be less desire to make payments early.which would stretch accounts payable.accounts receivable.and cash accounts. The ra mifications of this study include the finding of distinct levels of WCM measures for different industries.which tend to be stable over ti me. Many factors help to explain this discovery. The improving econom y during the period of the study may have resulted in improved turn over in some industries.while slowing turnover may have been a signal of troubles ahead. Our results should be interpreted cautiously. Our study takes places over a short time frame during a generally impr oving market. In addition. the survey suffers from survivorship bias –only the top firms within each industry are ranked each year and the composition of those firms within the industry can change annua lly.Further research may take one of two lines.First.there could bea study of whether stock prices respond to CFO magazine’s publication of working capital management rating.Second,there could be a study of which if any of the working capital management components relate to share price performance.Given our results,there studies need to take industry membership into consideration when estimating stock price reaction to working capital management performance.对整个行业中营运资金管理的研究格雷格Filbeck.Schweser学习计划托马斯M克鲁格.威斯康星大学拉克罗斯摘要:企业能够降低融资成本或者尽量减少绑定在流动资产上的成立基金数额来用于扩大现有的资金。

火是由人类活动或者机械故障,建筑物内的电器引起的1.1.介绍介绍介绍其他论文,考虑建筑物的设计的重力荷载,风和地震等一系列问题。

建筑物针对这些负载的影响的设计是相当大的程度上涵盖了工程的标准参照了建筑法规。

几乎在同一程度上,万一发生火灾,事实并非如此。

相反,正是如澳大利亚建筑法那样的法规明确了建筑防火安全的标准,如用as3600,as4100的方法确定耐火构件。

本文的目的就是要从工程角度考虑建筑设计消防安全,(如目前所做的风力或地震等其他荷载),同时将这种方法应用于当前规范要求的环境之中。

首先需要指出的是,设计一幢防火大楼只考虑建设结构或者是否有足够的结构性是远远不够的。

这是因为火可以直接通过烟雾和热量影响住户,还可以蔓延增加严重性,而其它对楼房的影响不具备这一特征。

尽管有这些评论,本文的大部分重点仍将集中于建筑结构的设计问题。

本文将选择一栋大楼的两种情况作为讨论的对象。

图1所示的多层办公楼利用了转换结构,跨过了一条铁路路轨。

这是在假定了广泛的轨道交通利用这些轨道基础上,考虑到了运费和内燃机车。

我们将从从消防安全角度考虑第一种情况,即转换结构。

这是被称为情况1,其中的关键问题是: 哪一级耐火要求用这种转换结构?这种转换结构又如何确定?这种情况已经选定,因为它显然不属于大多数建筑法规的正常的监管范围。

我们需要的是一项工程性的而不是指令性的解决办法。

第二种火灾形势(称为情况2)相应的消防局内不同层次的建设和涵盖了建筑法规。

选择这种情况是因为它将促成工程学方法的讨论以及如何把这些建设规章相衔接,因为两种工程和指令性的办法皆是可行的。

2.火灾的独特性2.火灾的独特性火灾的独特性介绍2.1介绍设计师无法控制风和地震等"自然"的现象,因而只能根据历史记载更合理的选择建筑物的位置,或者提高建筑的负荷能力。

SargentABSTRACTIn recent years, green consumption has become a main trend of the consumption in many developed countries and these countries began to make strict standards to restrict the entry of foreign products below their standards of environmental protection.Key words:Green Barriers; products; TradeIn recent years, green consumption has become a main trend of the consumption in many developed countries and these countries began to make strict standards to restrict the entry of foreign products below their standards of environmental protection. These regulations have many unfavorable influences on the export of developing countries and are generally known as "Green Barriers to trade". In accordance with the provisions of the Agreement on Green Barriers to Trade of WTO, "Green Barriers to Trade" is defined as the compulsory and arbitrary Green regulations, standards and conformity assessment procedures of the importing countries in the name of the protection of human health and environment that actually form barriers to trade with an aim to protect its home market and domestic products.1. Analysis on the causes of formation of "Green Trade Barriers"Firstly, the worsening of ecology is the major reason for "Green Barriers". With the development of industry and technology, the economy increases very fast and the human life has been improved. But at the same time, the development of economy is at a cost of the destruction of environment. The environmental problems have aroused public attention and the international society has begun to make laws to protect environment. In June, 1972, the United Nations published the StockholmGreen StandardsGreen standards refer to those compulsory Green standards provided through legislation. With their superiority in economy and technology, developed countries tend to make higher Green standards with no consideration on the interests of the developing countries. Such high Green standards will in fact constitute a barrier to the products from developing countries which are inferior in technology.2.3 Package RequirementsCertain developed countries stress too much on the protection of environment and require the products should be packed with materials that will have no harm to the environment. If the products are not packed in this way, they will not be allowed to sell in the developed countries. If such requirements are unnecessarily strict, they will be a barrier to the international trade.2.4 Sanitary and quarantine inspection systemOn the excuse of the protection of the health of human, animals and plants, developed countries tend to use very strict sanitary and quarantine inspection to restrict the importation of the products from the developing countries and protect their domestic industries.3. Influences of Green barriers on China's foreign tradeChina has suffered great loss due to the "Green barriers". In 2002, vegetables from Taizhou were prevented from entering Japan because of Japanese strict inspection and the price was greatly cut down. Also in 2002, the aquatic products from Ningbo were restricted by European Union (EU) because they could not reach the sanitary standards of EU. Due to Green trade barriers, 60 kinds of Chinese agricultural chemists were banned by EU because they could not reach the Green standards of EU. In accordance with the statistics of United Nations, China has suffered a loss of $7.4 billion in 2002 due to "Green barriers trade". China's export to EU, Japan, Korea and other countries decreases notably. Generally speaking, agricultural products and foodstuff, textile products and mechanical and electronic products are the three main industries which suffer great loss because of the strict Green barriers. Since these three products constitute the majority of Chinese exportation, we can easily draw a conclusion: "Green barriers to trade" has becomeone of the major obstacles in Chinese exportation.4. Countermeasures to the Green barriers of the developed countriesAs mentioned above, it is a fact that the Chinese export products are facing Greenbarriers of the developed countries and has suffered great loss. Therefore Chinese exporters should think carefully about the countermeasures to eliminate the unfavorable influences of such measures. First, we should make full use of the preferential treatment to the developing countries stipulated in the Agreement of Green trade barrier. According to the provisions of the Agreement of Green trade barrier, developed countries should take account of the special development, financial and trade needs of developing country members with a view to ensuring that such Green regulations, standards and conformity assessment procedures do not create unnecessary obstacles to exports from developing countries. So, as a developing member of WTO, China is entitled to such preferential treatment. Secondly, China should make use of the Dispute Settlement System of WTO to protect her interests. Different from GATT, WTO has set up a powerful dispute settlement system to solve the disputes between the members of WTO. So, if our interests are harmed by the unfair Green barriers of other WTO members, we can resort to Dispute Settlement Body to settle this dispute and urge other members to change their unfair practices so as to protect our interests. Thirdly, China should stress the protection of environment and take measures to improve the quality and Green level of her export products to meet higher Green standards, which will fundamentally solve the problem of Green barriers.References[1]John, Smith. 2007, Green trade protectionism to Chinese agricultural product export influence Economics ,4,34-56.[2] Anderson, J.L., 2001, The Greening of World Trade Issues, Journal of Marketing Research, 24, 347-356.[3] Gallagher, R., 2003, International Trade in Agricultural Products, Journal of General Management, 3, 1, 43-62.- 1 -经济研究杂志, 2006, 11: 24-27.绿色贸易壁垒及其对中国对外贸易的影响萨金特莱斯大学经济管理学院摘要:近年来,绿色消费在许多发达国家中已成为一个主要的消费趋势,这些发达国家开始采取严格的措施来限制一些国家的产品进入其国内市场。

中英文对照外文翻译(文档含英文原文和中文翻译)Bridge research in EuropeA brief outline is given of the development of the European Union, together withthe research platform in Europe. The special case of post-tensioned bridges in the UK is discussed. In order to illustrate the type of European research being undertaken, an example is given from the University of Edinburgh portfolio: relating to the identification of voids in post-tensioned concrete bridges using digital impulse radar.IntroductionThe challenge in any research arena is to harness the findings of different research groups to identify a coherent mass of data, which enables research and practice to be better focused. A particular challenge exists with respect to Europe where language barriers are inevitably very significant. The European Community was formed in the 1960s based upon a political will within continental Europe to avoid the European civil wars, which developed into World War 2 from 1939 to 1945. The strong political motivation formed the original community of which Britain was not a member. Many of the continental countries saw Britain’s interest as being purelyeconomic. The 1970s saw Britain joining what was then the European Economic Community (EEC) and the 1990s has seen the widening of the community to a European Union, EU, with certain political goals together with the objective of a common European currency.Notwithstanding these financial and political developments, civil engineering and bridge engineering in particular have found great difficulty in forming any kind of common thread. Indeed the educational systems for University training are quite different between Britain and the European continental countries. The formation of the EU funding schemes —e.g. Socrates, Brite Euram and other programs have helped significantly. The Socrates scheme is based upon the exchange of students between Universities in different member states. The Brite Euram scheme has involved technical research grants given to consortia of academics and industrial partners within a number of the states—— a Brite Euram bid would normally be led by partners within a number of the statesan industrialist.In terms of dissemination of knowledge, two quite different strands appear to have emerged. The UK and the USA have concentrated primarily upon disseminating basic research in refereed journal publications: ASCE, ICE and other journals. Whereas the continental Europeans have frequently disseminated basic research at conferences where the circulation of the proceedings is restricted.Additionally, language barriers have proved to be very difficult to break down. In countries where English is a strong second language there has been enthusiastic participation in international conferences based within continental Europe —e.g. Germany, Italy, Belgium, The Netherlands and Switzerland. However, countries where English is not a strong second language have been hesitant participants }—e.g. France.European researchExamples of research relating to bridges in Europe can be divided into three types of structure:Masonry arch bridgesBritain has the largest stock of masonry arch bridges. In certain regions of the UK up to 60% of the road bridges are historic stone masonry arch bridges originally constructed for horse drawn traffic. This is less common in other parts of Europe as many of these bridges were destroyed during World War 2.Concrete bridgesA large stock of concrete bridges was constructed during the 1950s, 1960s and 1970s. At the time, these structures were seen as maintenance free. Europe also has a large number of post-tensioned concrete bridges with steel tendon ducts preventing radar inspection. This is a particular problem in France and the UK.Steel bridgesSteel bridges went out of fashion in the UK due to their need for maintenance as perceived in the 1960s and 1970s. However, they have been used for long span and rail bridges, and they are now returning to fashion for motorway widening schemes in the UK.Research activity in EuropeIt gives an indication certain areas of expertise and work being undertaken in Europe, but is by no means exhaustive.In order to illustrate the type of European research being undertaken, an example is given from the University of Edinburgh portfolio. The example relates to the identification of voids in post-tensioned concrete bridges, using digital impulse radar.Post-tensioned concrete rail bridge analysisOve Arup and Partners carried out an inspection and assessment of the superstructure of a 160 m long post-tensioned, segmental railway bridge in Manchester to determine its load-carrying capacity prior to a transfer of ownership, for use in the Metrolink light rail system..Particular attention was paid to the integrity of its post-tensioned steel elements.Physical inspection, non-destructive radar testing and other exploratory methods were used to investigate for possible weaknesses in the bridge.Since the sudden collapse of Ynys-y-Gwas Bridge in Wales, UK in 1985, there has been concern about the long-term integrity of segmental, post-tensioned concrete bridges which may b e prone to ‘brittle’ failure without warning. The corrosion protection of the post-tensioned steel cables, where they pass through joints between the segments, has been identified as a major factor affecting the long-term durability and consequent strength of this type of bridge. The identification of voids in grouted tendon ducts at vulnerable positions is recognized as an important step in the detection of such corrosion.Description of bridgeGeneral arrangementBesses o’ th’ Barn Bridge is a 160 m long, three span, segmental, post-tensionedconcrete railway bridge built in 1969. The main span of 90 m crosses over both the M62 motorway and A665 Bury to Prestwick Road. Minimum headroom is 5.18 m from the A665 and the M62 is cleared by approx 12.5 m.The superstructure consists of a central hollow trapezoidal concrete box section 6.7 m high and 4 m wide. The majority of the south and central spans are constructed using 1.27 m long pre-cast concrete trapezoidal box units, post-tensioned together. This box section supports the in site concrete transverse cantilever slabs at bottom flange level, which carry the rail tracks and ballast.The center and south span sections are of post-tensioned construction. These post-tensioned sections have five types of pre-stressing:1. Longitudinal tendons in grouted ducts within the top and bottom flanges.2. Longitudinal internal draped tendons located alongside the webs. These are deflected at internal diaphragm positions and are encased in in site concrete.3. Longitudinal macalloy bars in the transverse cantilever slabs in the central span .4. Vertical macalloy bars in the 229 mm wide webs to enhance shear capacity.5. Transverse macalloy bars through the bottom flange to support the transverse cantilever slabs.Segmental constructionThe pre-cast segmental system of construction used for the south and center span sections was an alternative method proposed by the contractor. Current thinkingire suggests that such a form of construction can lead to ‘brittle’ failure of the ententire structure without warning due to corrosion of tendons across a construction joint,The original design concept had been for in site concrete construction.Inspection and assessmentInspectionInspection work was undertaken in a number of phases and was linked with the testing required for the structure. The initial inspections recorded a number of visible problems including:Defective waterproofing on the exposed surface of the top flange.Water trapped in the internal space of the hollow box with depths up to 300 mm.Various drainage problems at joints and abutments.Longitudinal cracking of the exposed soffit of the central span.Longitudinal cracking on sides of the top flange of the pre-stressed sections.Widespread sapling on some in site concrete surfaces with exposed rusting reinforcement.AssessmentThe subject of an earlier paper, the objectives of the assessment were:Estimate the present load-carrying capacity.Identify any structural deficiencies in the original design.Determine reasons for existing problems identified by the inspection.Conclusion to the inspection and assessmentFollowing the inspection and the analytical assessment one major element of doubt still existed. This concerned the condition of the embedded pre-stressing wires, strands, cables or bars. For the purpose of structural analysis these elements、had been assumed to be sound. However, due to the very high forces involved,、a risk to the structure, caused by corrosion to these primary elements, was identified.The initial recommendations which completed the first phase of the assessment were:1. Carry out detailed material testing to determine the condition of hidden structural elements, in particularthe grouted post-tensioned steel cables.2. Conduct concrete durability tests.3. Undertake repairs to defective waterproofing and surface defects in concrete.Testing proceduresNon-destructi v e radar testingDuring the first phase investigation at a joint between pre-cast deck segments the observation of a void in a post-tensioned cable duct gave rise to serious concern about corrosion and the integrity of the pre-stress. However, the extent of this problem was extremely difficult to determine. The bridge contains 93 joints with an average of 24 cables passing through each joint, i.e. there were approx. 2200 positions where investigations could be carried out. A typical section through such a joint is that the 24 draped tendons within the spine did not give rise to concern because these were protected by in site concrete poured without joints after the cables had been stressed.As it was clearly impractical to consider physically exposing all tendon/joint intersections, radar was used to investigate a large numbers of tendons and hence locate duct voids within a modest timescale. It was fortunate that the corrugated steel ducts around the tendons were discontinuous through the joints which allowed theradar to detect the tendons and voids. The problem, however, was still highly complex due to the high density of other steel elements which could interfere with the radar signals and the fact that the area of interest was at most 102 mm wide and embedded between 150 mm and 800 mm deep in thick concrete slabs.Trial radar investigations.Three companies were invited to visit the bridge and conduct a trial investigation. One company decided not to proceed. The remaining two were given 2 weeks to mobilize, test and report. Their results were then compared with physical explorations.To make the comparisons, observation holes were drilled vertically downwards into the ducts at a selection of 10 locations which included several where voids were predicted and several where the ducts were predicted to be fully grouted. A 25-mm diameter hole was required in order to facilitate use of the chosen horoscope. The results from the University of Edinburgh yielded an accuracy of around 60%.Main radar sur v ey, horoscope verification of v oids.Having completed a radar survey of the total structure, a baroscopic was then used to investigate all predicted voids and in more than 60% of cases this gave a clear confirmation of the radar findings. In several other cases some evidence of honeycombing in the in site stitch concrete above the duct was found.When viewing voids through the baroscopic, however, it proved impossible to determine their actual size or how far they extended along the tendon ducts although they only appeared to occupy less than the top 25% of the duct diameter. Most of these voids, in fact, were smaller than the diameter of the flexible baroscopic being used (approximately 9 mm) and were seen between the horizontal top surface of the grout and the curved upper limit of the duct. In a very few cases the tops of the pre-stressing strands were visible above the grout but no sign of any trapped water was seen. It was not possible, using the baroscopic, to see whether those cables were corroded.Digital radar testingThe test method involved exciting the joints using radio frequency radar antenna: 1 GHz, 900 MHz and 500 MHz. The highest frequency gives the highest resolution but has shallow depth penetration in the concrete. The lowest frequency gives the greatest depth penetration but yields lower resolution.The data collected on the radar sweeps were recorded on a GSSI SIR System 10.This system involves radar pulsing and recording. The data from the antenna is transformed from an analogue signal to a digital signal using a 16-bit analogue digital converter giving a very high resolution for subsequent data processing. The data is displayed on site on a high-resolution color monitor. Following visual inspection it isthen stored digitally on a 2.3-gigabyte tape for subsequent analysis and signal processing. The tape first of all records a ‘header’ noting the digital radar settings together with the trace number prior to recording the actual data. When the data is played back, one is able to clearly identify all the relevant settings —making for accurate and reliable data reproduction.At particular locations along the traces, the trace was marked using a marker switch on the recording unit or the antenna.All the digital records were subsequently downloaded at the University’s NDT laboratory on to a micro-computer.(The raw data prior to processing consumed 35 megabytes of digital data.) Post-processing was undertaken using sophisticated signal processing software. Techniques available for the analysis include changing the color transform and changing the scales from linear to a skewed distribution in order to highlight、突出certain features. Also, the color transforms could be changed to highlight phase changes. In addition to these color transform facilities, sophisticated horizontal and vertical filtering procedures are available. Using a large screen monitor it is possible to display in split screens the raw data and the transformed processed data. Thus one is able to get an accurate indication of the processing which has taken place. The computer screen displays the time domain calibrations of the reflected signals on the vertical axis.A further facility of the software was the ability to display the individual radar pulses as time domain wiggle plots. This was a particularly valuable feature when looking at individual records in the vicinity of the tendons.Interpretation of findingsA full analysis of findings is given elsewhere, Essentially the digitized radar plots were transformed to color line scans and where double phase shifts were identified in the joints, then voiding was diagnosed.Conclusions1. An outline of the bridge research platform in Europe is given.2. The use of impulse radar has contributed considerably to the level of confidence in the assessment of the Besses o’ th’ Barn Rail Bridge.3. The radar investigations revealed extensive voiding within the post-tensioned cable ducts. However, no sign of corrosion on the stressing wires had been foundexcept for the very first investigation.欧洲桥梁研究欧洲联盟共同的研究平台诞生于欧洲联盟。

机器人技术发展趋势论文中英文对照资料外文翻译文献

机器人技术发展趋势作者:Jim Pinto,加利福利亚州圣迭亚哥·美国谈到机器人,现实仍落后于科幻小说。

但是,仅仅因为机器人在过去的几十年没有实现它们的承诺,并不意味着机器人的时代不会到来,或早或晚。

事实上,多种先进技术的影响已经使得机器人的时代变得更近——更小、更便宜、更实用和更具成本效益。

肌肉、骨骼和大脑任何一个机器人都有三方面:·肌肉——有效联系有关物理荷载以便于机器人运动。

·骨骼——一个机器人的物理结构取决于它所做的工作;它的尺寸大小和重量则取决于它的物理荷载。

·大脑——机器人智能;它能独立思考和做什么;需要多少人工互动。

由于机器人在科幻世界中所被描绘过的方式,很多人希望机器人在外型上与人类相似。

但事实上,机器人的外形更多地取决于它所做的工作或具备的功能。

很多一点儿也不像人的机器也被清楚地归为机器人。

同样,很多看起来像人的机器却还是仅仅属于机械结构和玩具。

很多早期的机器人是除了有很大力气而毫无其他功能的大型机器。

老式的液压动力机器人已经被用来执行3-D任务即平淡、肮脏和危险的任务。

由于第一产业技术的进步,完全彻底地改进了机器人的性能、业绩和战略利益。

比如,20世纪80年代,机器人开始从液压动力转换成为电动单位。

精度和性能也提高了。

工业机器人已经在工作时至今日,全世界机器人的数量已经接近100万,其中超过半数的机器人在日本,而仅仅只有15%在美国。

几十年前,90%的机器人是服务于汽车生产行业,通常用于做大量重复的工作。

现在,只有50%的机器人用于汽车制造业,而另一半分布于工厂、实验室、仓库、发电站、医院和其他的行业。

机器人用于产品装配、危险物品处理、油漆喷雾、抛光、产品的检验。

用于清洗下水道,探测炸弹和执行复杂手术的各种任务的机器人数量正在稳步增加,在未来几年内将继续增长。

机器人智能即使是原始的智力,机器人已经被证明了在生产力、效率和质量方面都能够创造良好的效益。
