    The focus of a parabola rolling without sliding along a straight line traces a catenary. We give some historical notes on this classical kinematical construction, observe that it was rediscovered in a recent article, and give a simpler and more geometric alternative derivation.

    2015-01-01

    This work explores a simple model of a slender, flexible structure in a uniform flow, providing analytical solutions for the translating, axially flowing equilibria of strings subjected to a uniform body force and drag forces linear in the velocities. The classical catenaries are extended to a five-parameter family of curves. A sixth parameter affects the tension in the curves. Generic configurations are planar, represented by a single first order equation for the tangential angle. The effects of varying parameters on representative shapes, orbits in angle-curvature space, and stress distributions are shown. As limiting cases, the solutions include configurations corresponding to "lariat chains" and the towing, reeling, and sedimentation of flexible cables in a highly viscous fluid. Regions of parameter space corresponding to infinitely long, semi-infinite, and finite length curves are delineated. Almost all curves subtend an angle less than $\\pi$ radians, but curious special cases with doubled or infinite ra...

    The quest to find the equation of a catenary makes an ideal investigation for upper secondary students. In the modelling exercise that follows, no knowledge of calculus is required to gain a fairly good understanding of the nature of the curve. This investigation is best described as a scientific investigation--a "hands on" experience that…

  4. Risers. Fatigue of steel catenary risers

    Steel catenary risers (SCR) are used in the Golf of Mexico (Auger,...), Brazil (Marlim), and soon West Africa (Bonga). Some risers have been instrumented to better understand their behaviour, for instance in the Allegheny Field or the Marlim field. One of the main problem is the interaction between the riser and the soil, since it may create high stresses when the riser is excited by top motion or Vortex-Induced Vibrations (VIV), leading to low fatigue life near the Touch Down Point (TDP). The objective of the present paper is to analyze the influence of the soil on the fatigue of a SCR. A riser configuration is defined and parametric studies are conducted on the soil stiffness, the riser characteristics and the geographic location. The fatigue considered is either due to currents (VIV) or waves (top excitation). For the latter case, several fatigue methods are also compared. (authors)

    The catenary is the curve that a free-hanging chain assumes under its own weight, and thought to be a "true mathematical and mechanical form" in architecture by Robert Hooke in the 1670s, with nevertheless no significant phenomena observed in optics. We show that the optical catenary can serve as a unique building block of metasurfaces to produce continuous and linear phase shift covering [0, 2π], a mission that is extremely difficult if not impossible for state-of-the-art technology. Via catenary arrays, planar optical devices are designed and experimentally characterized to generate various kinds of beams carrying orbital angular momentum (OAM). These devices can operate in an ultra-broadband spectrum because the anisotropic modes associated with the spin-orbit interaction are almost independent of the incident light frequency. By combining the optical and topological characteristics, our approach would allow the complete control of photons within a single nanometric layer. PMID:26601283

    Full Text Available This study is aimed at developing automated methods to recognize railroad infrastructure from 3D LIDAR data. Railroad infrastructure includes rail tracks, contact cables, catenary cables, return current cables, masts, and cantilevers. The LIDAR dataset used in this study is acquired by placing an Optech Lynx mobile mapping system on a railcar, operating at 125 km/h. The acquired dataset covers 550 meters of Austrian rural railroad corridor comprising 31 railroad key elements and containing only spatial information. The proposed methodology recognizes key components of the railroad corridor based on their physical shape, geometrical properties, and the topological relationships among them. The developed algorithms managed to recognize all key components of the railroad infrastructure, including two rail tracks, thirteen masts, thirteen cantilevers, one contact cable, one catenary cable, and one return current cable. The results are presented and discussed both at object level and at point cloud level. The results indicate that 100% accuracy and 100% precision at the object level and an average of 96.4% accuracy and an average of 97.1% precision at point cloud level are achieved.

  8. 3D CATENARY CURVE FITTING FOR GEOMETRIC CALIBRATION

    Directory of Open Access Journals (Sweden)

    2012-09-01

    Full Text Available In modern road surveys, hanging power cables are among the most commonly-found geometric features. These cables are catenary curves that are conventionally modelled with three parameters in 2D Cartesian space. With the advent and popularity of the mobile mapping system (MMS, the 3D point clouds of hanging power cables can be captured within a short period of time. These point clouds, similarly to those of planar features, can be used for feature-based self-calibration of the system assembly errors of an MMS. However, to achieve this, a well-defined 3D equation for the catenary curve is needed. This paper proposes three 3D catenary curve models, each having different parameters. The models are examined by least squares fitting of simulated data and real data captured with an MMS. The outcome of the fitting is investigated in terms of the residuals and correlation matrices. Among the proposed models, one of them could estimate the parameters accurately and without any extreme correlation between the variables. This model can also be applied to those transmission lines captured by airborne laser scanning or any other hanging cable-like objects.

  9. Center vortices, area law and the catenary solution

    2015-12-01

    We present meson-meson (Wilson loop) correlators in Z(2) center vortex models for the infrared sector of Yang-Mills theory, i.e. a hypercubic lattice model of random vortex surfaces and a continuous (2 + 1)-dimensional model of random vortex lines. In particular, we calculate quadratic and circular Wilson loop correlators in the two models, respectively, and observe that their expectation values follow the area law and show string breaking behavior. Further, we calculate the catenary solution for the two cases and try to find indications for minimal surface behavior or string surface tension leading to string constriction.

    A deep water installation method has been developed to self-install Steel Catenary Risers (SCRs) from Floating Production Units (FPUs). Multiple risers can be deployed from an FPU using modular J-lay equipment while the pipe is joined by welding or mechanical connectors. A DP (Dynamically Positioned) work boat pulls the pipeline outward from the FPU as the pipe string is lowered from the J-lay tower. The work boat moves incrementally and maintains an acceptable catenary configuration while sliding the pipeline along the seabed. A pipeline may be pulled to long distances (10 kilometers or more) for sub sea tie-ins to a wellhead or another pipeline. When the pipeline is extended to its final length, the SCR is pulled into its final topside angle and supported in a receptacle on the FPU. This method can be applied to any deep water floating system. Having J-lay equipment onboard an FPU enables riser installation to proceed according to field development schedules, thus avoiding pipeline vessel mobilizations. This results in substantial savings over typical deep water pipeline vessel mobilization, stand-by and day-rate charges, which in turn leads to more economical deep water field developments. The paper will describe the equipment and lay operation of multiple SCRs from a typical FPU. (author)

  11. Nonlinear analysis of wind-induced vibration of high-speed railway catenary and its influence on pantograph-catenary interaction

    Song, Yang; Liu, Zhigang; Wang, Hongrui; Lu, Xiaobing; Zhang, Jing

    2016-06-01

    The wind-induced vibration of the high-speed catenary and the dynamic behaviour of the pantograph-catenary under stochastic wind field are firstly analysed. The catenary model is established based on nonlinear cable and truss elements, which can fully describe the nonlinearity of each wire and the initial configuration. The model of the aerodynamic forces acting on the messenger/contact wire is deduced by considering the effect of the vertical and horizontal fluctuating winds. The vertical and horizontal fluctuating winds are simulated by employing the Davenport and Panofsky spectrums, respectively. The aerodynamic coefficients of the contact/messenger wire are calculated through computational fluid dynamics. The wind-induced vibration response of catenary is analysed with different wind speeds and angles. Its frequency-domain characteristics are discussed using Auto Regression model. Finally, a pantograph model is introduced and the contact force of the pantograph-catenary under stochastic wind is studied. The results show that both the wind speed and the attack angle exert a significant effect on the wind-induced vibration. The existence of the groove on the contact wire cross-section leads to a significant change of the aerodynamic coefficient, which affects largely the aerodynamic forces applied on the catenary wires, as well as the vibration response. The vibration frequency with high spectral power mainly concentrates on the predominant frequency of the fluctuating wind and the natural frequency of catenary. The increase in the wind speed results in a significant deterioration of the current collection. The numerical example shows that a relatively stable current collection can be ensured when the wind flows at the relatively horizontal direction.

  12. Investigation of Collision Behavior of Hoisting Catenaries during a Lifting Cycle in Coal Mines

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available This investigation focused on the analyses of transverse vibrations of mine hoisting catenaries where collision between adjacent ropes is more likely to occur. To support the analyses of transverse vibrations of catenaries, theoretical correlation models for longitudinal tension and transverse vibration were first established. Based on a severe rope collision case, on-site measurements and numerical simulations were performed. The research results indicated that the external second-order excitation frequency induced by axial fluctuations of head sheave was the primary excitation frequency, which was closer to the resonance frequency. Furthermore, the effects of excitation amplitude and imbalanced tension were also investigated revealing that larger excitation amplitude contributes to larger response amplitude and the maximum response amplitude of a catenary is sensitive to imbalanced rope tension. Eventually, new solutions, which will facilitate hoisting catenary operation beyond the resonance frequency range, were proposed.

    A chain assumes the well-known shape known as a catenary when it hangs loosely from two points in a gravitational field. The correct solution of the catenary was one of the early triumphs of the newly invented calculus of variations at the end of the 17th century. Here we revisit the catenary and show that, for a chain hanging from a horizontal…

  14. Modelling of structural flexiblity in multibody railroad vehicle systems

    2013-07-01

    This paper presents a review of recent research investigations on the computer modelling of flexible bodies in railroad vehicle systems. The paper will also discuss the influence of the structural flexibility of various components, including the wheelset, the truck frames, tracks, pantograph/catenary systems, and car bodies, on the dynamics of railroad vehicles. While several formulations and computer techniques for modelling structural flexibility are discussed in this paper, a special attention is paid to the floating frame of reference formulation which is widely used and leads to reduced-order finite-element models for flexible bodies by employing component modes synthesis techniques. Other formulations and numerical methods such as semi-analytical approaches, absolute nodal coordinate formulation, finite-segment method, boundary elements method, and discrete elements method are also discussed. This investigation is motivated by the fact that the structural flexibility can have a significant effect on the overall dynamics of railroad vehicles, ride comfort, vibration suppression and noise level reduction, lateral stability, track response to vehicle forces, stress analysis, wheel-rail contact forces, wear and crashworthiness.

  15. Experiments and models of DNA nano-catenary patterns manipulated by liquid flow

    International Nuclear Information System (INIS)

    Individual DNA molecules were first stretched by a centrifugal force and adsorbed on a modified mica surface. Then, a liquid flow was guided across the surface along a direction perpendicular to the aligned DNA strands. Some nano-catenary-like patterns of DNA molecules were formed, which were revealed by atomic force microscopy. A physical mechanism called the 's-suspension bridge' model has been presented, by which the features of the catenary-like patterns of DNA molecules can be understood quantitatively quite well

  20. Camera-based measurement for transverse vibrations of moving catenaries in mine hoists using digital image processing techniques

    International Nuclear Information System (INIS)

    This paper proposes a novel, non-contact, sensing method to measure the transverse vibrations of hoisting catenaries in mine hoists. Hoisting catenaries are typically moving cables and it is not feasible to use traditional methods to measure their transverse vibrations. In order to obtain the transverse displacements of an arbitrary point in a moving catenary, by superposing a mask image having the predefined reference line perpendicular to the hoisting catenaries on each frame of the processed image sequence, the dynamic intersecting points with a grey value of 0 in the image sequence could be identified. Subsequently, by traversing the coordinates of the pixel with a grey value of 0 and calculating the distance between the identified dynamic points from the reference, the transverse displacements of the selected arbitrary point in the hoisting catenary can be obtained. Furthermore, based on a theoretical model, the reasonability and applicability of the proposed camera-based method were confirmed. Additionally, a laboratory experiment was also carried out, which then validated the accuracy of the proposed method. The research results indicate that the proposed camera-based method is suitable for the measurement of the transverse vibrations of moving cables. (paper)

  1. Effect of Hoisting Load on Transverse Vibrations of Hoisting Catenaries in Floor Type Multirope Friction Mine Hoists

    Directory of Open Access Journals (Sweden)

    Jiannan Yao

    2016-01-01

    Full Text Available The effect of hoisting load on transverse vibrations of hoisting catenaries during lifting in coal mines was investigated in this study. Firstly, dynamic analyses of the vertical hoisting rope were performed. The results show that transverse vibration plays the dominating role in the coupled dynamics of the vertical rope subjected to external excitation induced by axial fluctuations of head sheave, and the rope tension can be approximated by the quasistatic tension. Secondly, employing dynamic simulations, the effect of hoisting load on the transverse vibrations of hoisting catenaries was discussed. The results show that, under the second-order excitation frequency, a discrepant large transverse amplitude will be excited when the hoisting load ranges from 0 to 5000 kg, leading to collision between the two adjacent catenaries and accelerating the rupture of rope. To solve this problem, according to simulation curves, the self-weight of conveyance (preload can be optimized from 39500 kg to 49500 kg. Eventually, on-site measurements were performed on the studied machine, validating the accuracy of the effect of hoisting load on transverse vibrations of hoisting catenaries. This investigation will greatly support facility maintenance, machine design, and even engineering optimization for floor type multirope friction mine hoists.

    The existing lightning protection system at Pad 39B for the Space Shuttle is an outgrowth of a system that was put in place for the Apollo Program. Dr. Frank Fisher of Lightning Technologies was a key participant in the design and implementation of that system. He conveyed to the NESC team that the catenary wire provision was put in place quickly (as assurance against possible vehicle damage causing critical launch delays) rather than being implemented as a comprehensive system designed to provide a high degree of guaranteed protection. Also, the technology of lightning protection has evolved over time with considerable work being conducted by groups such as the electric utilities companies, aircraft manufacturers, universities, and others. Several accepted present-day methods for analysis of lightning protection were used by Drs. Medelius and Mata to study the expected lightning environment for the Pad 39B facility and to analyze the degree of protection against direct lightning attachment to the Space Shuttle. The specific physical configuration directly affects the vulnerability, so cases that were considered included the RSS next to and rolled back from the Space Shuttle, and the GOx Vent Arm both extended and withdrawn from the ET. Elements of the lightning protection system at Pad 39B are shown in Figure 6.0-1 and consist of an 80 foot insulating mast on top of the Fixed Support Structure (FSS), a catenary wire system that runs from the mast in a North/South direction to grounds 1000 feet away on each side of the mast, the RSS which can either be next to or away from the Space Shuttle, and a GOx vent that can either be extended or retracted from the top of the ET.

    2010-01-01

    The mathematical model of vehicle supply system as well as the mathematical model of main circuit of locomotive with asynchronous motors have been described in this article. The necessity of analysis of disturbances caused by distorted current run of drive motors emerged together with the introduction of high power vehicles with power electronic converters. Analysis of the compatibility of traction high current circuits with circuits of the signal and traffic control systems requires the knowledge of current spectrum in a catenary, which has been taken by a vehicle. The author has described the algebraic method of calculating of the spectrum amplitudes in a catenary. It does not require laborious and time-consuming simulations of a system, which considerably decreases preliminary costs of designation and dimensioning of a vehicle drive system.

    DB Systemtechnik is a high-performing, customer-driven service provider that, as well as authoritatively serving the Deutsche Bahn Group by dint of its specialist knowledge is also increasingly active on the global railway market. Development and testing of pantograph models and catenary systems have been part of the company's essential activity fields from the beginning. Therefore, an efficient and high-performing simulation tool is indispensable. That is why DB Systemtechnik spent high efforts to develop the program PrOSA in cooperation with the Heinz-Nixdorf-Institut (HNI) of the university Paderborn to simulate the interaction of pantograph and catenary. This article gives an overview of the most relevant properties of PrOSA. Furthermore, it is described how the benchmark requirements were implemented and processed.

  7. A New Contactless Fault Diagnosis Approach for Pantograph-Catenary System Using Pattern Recognition and Image Processing Methods

    Directory of Open Access Journals (Sweden)

    AYDIN, I.

    2014-08-01

    Full Text Available Comfort and safety of railway transport has become more important as train speeds continue to increase. In electrified railways, the electrical current of the train is produced by the sliding contact between the pantograph and catenary. The quality of the current depends on the reliability of contact between the pantograph and catenary. So, pantograph inspection is very important task in electrified railways and it is periodically made for preventing dangerous situations. This inspection is operated manually by taking the pantograph to the service for visual anomalies. However, this monitoring is impractical because of time consuming and slowness, as locomotive remains disabled. An innovative method based on image processing and pattern recognition is proposed in this paper for online monitoring of the catenary-pantograph interaction. The images are acquired from a digital line-scan camera. Data are simultaneously processed according to edge detection and Hough transform, and then the obtained features are provided to a D-Markov based state machine, and the pantograph related faults, such as overheating of the pantograph strip, bursts of arcing, and irregular positioning of the contact line are diagnosed. The proposed method is verified by real faulty and healthy pantograph videos.

    2014-01-01

    A prediction model of the deepwater steel catenary riser VIV is proposed based on the forced oscillation test data, taking into account the riser-seafloor interaction for the cross-flow VIV-induced fatigue damage at touch-down point (TDP). The model will give more reasonable simulation of SCR response near TDP than the previous pinned truncation model. In the present model, the hysteretic riser-soil interaction model is simplified as the linear spring and damper to simulate the seafloor, and the damping is obtained according to the dissipative power during one periodic riser-soil interaction. In order to validate the model, the comparison with the field measurement and the results predicted by Shear 7 program of a full-scale steel catenary riser is carried out. The main induced modes, mode frequencies and response amplitude are in a good agreement. Furthermore, the parametric studies are carried out to broaden the understanding of the fatigue damage sensitivity to the upper end in-plane offset and seabed characteristics. In addition, the fatigue stress comparison at TDP between the truncation riser model and the present full riser model shows that the existence of touch-down zones is very important for the fatigue damage assessment of steel catenary riser at TDP.

    Steel catenary riser (SCR) is the transmission device between the seabed and the floating production facilities. As developments move into deeper water, the fatigue life of the riser can become critical to the whole production system, especially due to the vortex-induced vibration (VIV), which is the key factor to operational longevity. As a result, experimental investigation about VIV of the riser was performed in a large plane pool which is 60 m long, 36 m wide and 6.5 m deep. Experiments were developed to study the influence of current speed and seabed on VIV of SCR. The results show that amplitudes of strain and response frequencies increase with the current speed both in cross-flow (CF) and in-line (IL). When the current speed is high, multi-mode response is observed in the VIV motion. The amplitudes of strain in IL direction are not much smaller than those in CF direction. The seabed has influence on the response frequencies of riser and the positions of damage for riser.

    Steel catenary risers (SCRs) have been successfully deployed on the Shell Auger TLP in the Gulf of Mexico and will also be deployed on the Shell Mars TLP. There is considerable interest in using SCRs for other applications, in particular for semi-sub based FPS systems. Petrobras is developing an SCR for installation on the P-XVIII platform, located in the Marlim Field, Campos Basin, in a water depth of 910 meters. The riser will be a dead-ended prototype which will be monitored for a period of up to one year. Subsequently, it will be connected via flexible piping to the P-XXVI platform, located approximately 5 kilometers from P-XVIII. This paper describes the design, materials, components, specification and installation of the Petrobras P-XVIII SCR. The static/dynamic design, VIV analysis and fatigue analysis methodologies are discussed in detail and results are presented. Important aspects of the flex joint design and specification are discussed. This project represents the first application of SCRs to semi-sub based FPS systems. In addition, it is the first use of SCRs outside of the Gulf of Mexico.

    Railroads are important to the U.S. economy. They transport freight efficiently, requiring less energy and emitting fewer pollutants than other modes of surface transportation. While the railroad industry has steadily improved its fuel efficiency--by 16% over the last decade--more can, and needs to, be done. The ability of locomotive manufacturers to conduct research into fuel efficiency and emissions reduction is limited by the small number of locomotives manufactured annually. Each year for the last five years, the two North American locomotive manufacturers--General Electric Transportation Systems and the Electro-Motive Division of General Motors--have together sold about 800 locomotives in the United States. With such a small number of units over which research costs can be spread, outside help is needed to investigate all possible ways to reduce fuel usage and emissions. Because fuel costs represent a significant portion of the total operating costs of a railroad, fuel efficiency has always been an important factor in the design of locomotives and in the operations of a railroad. However, fuel efficiency has recently become even more critical with the introduction of strict emission standards by the U.S. Environmental Protection Agency, to be implemented in stages (Tiers 0, 1, and 2) between 2000 and 2005. Some of the technologies that could be employed to meet the emission standards may negatively affect fuel economy--by as much as 10-15% when emissions are reduced to Tier 1 levels. Lowering fuel economy by that magnitude would have a serious impact on the cost to the consumer of goods shipped by rail, on the competitiveness of the railroad industry, and on this country's dependence on foreign oil. Clearly, a joint government/industry R&D program is needed to help catalyze the development of advanced technologies that will substantially reduce locomotive engine emissions while also improving train system energy efficiency.

  15. Dynamics of Large-Truncated Mooring Systems Coupled with A Catenary Moored Semi-Submersible

    Institute of Scientific and Technical Information of China (English)

    徐胜; 嵇春艳

    2014-01-01

    With the floating structures pushing their activities to the ultra-deep water, model tests have presented a challenge due to the limitation of the existing wave basins. Therefore, the concept of truncated mooring system is implemented to replace the full depth mooring system in the model tests, which aims to have the same dynamic responses as the full depth system. The truncated mooring system plays such a significant role that extra attention should be paid to the mooring systems with large truncation factor. Three different types of large truncation factor mooring system are being employed in the simulations, including the homogenously truncated mooring system, non-homogenously truncated mooring system and simplified truncated mooring system. A catenary moored semi-submersible operating at 1000 m water depth is presented. In addition, truncated mooring systems are proposed at the truncated water depth of 200 m. In order to explore the applicability of these truncated mooring systems, numerical simulations of the platform’s surge free decay interacting with three different styles of truncated mooring systems are studied in calm water. Furthermore, the mooring-induced damping of the truncated mooring systems is simulated in the regular wave. Finally, the platform motion responses and mooring line dynamics are simulated in irregular wave. All these simulations are implemented by employing full time domain coupled dynamic analysis, and the results are compared with those of the full depth simulations in the same cases. The results show that the mooring-induced damping plays a significant role in platform motion responses, and all truncated mooring systems are suitable for model tests with appropriate truncated mooring line diameters. However, a large diameter is needed for simplified truncated mooring lines. The suggestions are given to the selection of truncated mooring system for different situations as well as to the truncated mooring design criteria.

  16. Multiaxial Fatigue Analyses of Stress Joints for Deepwater Steel Catenary Risers

    Institute of Scientific and Technical Information of China (English)

    ZHENG Wen-qing; YANG He-zhen; LI Qing-quan

    2012-01-01

    In the present study,the dynamic and fatigue characteristics of two types of stress joints are investigated under ocean environmental condition.Connected with the riser and the platform,stress joint at the vessel hang-off position should be one of the main critical design challenges for a steel catenary riser (SCR) in deepwater.When the riser is under a high pressure and deepwater working condition,the stress state for the joint is more complex,and the fatigue damage is easy to occur at this position.Stress joint discussed in this paper includes two types:Tapered Stress Joint (TSJ) and Sleeved Stress Joint (SSJ),and multiaxial fatigue analysis results are given for comparison.Global dynamic analysis for an SCR is performed fiust,and then the local boundary conditions obtained from the previous analysis are applied to the stress joint FE model for the later dynamic and multiaxial fatigue analysis.Results indicate that the stress level is far lower than the yield limit of material and the damage induced by fatigue needs more attention.Besides,the damage character of the two types of stress joints differs:for TSJ,the place where the stress joint connects with the riser is easy to occur fatigue damage; for SSJ,the most probable position is at the place where the end of the inner sleeve pipe contacts with the riser body.Compared with SSJ,TSJ shows a higher stress level but better fatigue performance,and it will have a higher material cost.In consideration of various factors,designers should choose the most suitable type and also geometric parameters.

  17. The Cost of Railroad Regulation

    DEFF Research Database (Denmark)

    Federico, Giovanni; Sharp, Paul R.

    We investigate the costs of transportation regulation using the example of agricultural markets in the United States. Using a large database of prices by state of agricultural commodities, we find that the coefficient of variation (as a measure of market integration between states) falls for many...... commodities until the First World War. We demonstrate that this reflected changes in transportation costs which in turn in the long run depended on productivity growth in railroads. 1920 marked a change in this relationship, however, and between the First and Second World Wars we find considerable...

  6. Top local cohomology and the catenary of the unmixed part of support of a finitely generated module

    International Nuclear Information System (INIS)

    Let (R,m) be a Noetherian local ring and M a finitely generated R-module with dim M = d. This paper is concerned with the following property for the top local cohomology Hmd(M): AnnR(0:Hmd (M) p) = p for all prime ideals p is a subset of AnnRHmd(M). It is shown that this property is equivalent to the catenary of the unmixed part Supp M/UM(0) of the support of M, where UM(0) is the largest submodule of M of dimension less than d. Some characterizations of this property in terms of systems of parameters and relations between the unmixed parts of Supp M and Supp M-circumflex are given. A connection to the so-called co-localization is discussed. (author)

    中国高速铁路多采用高架桥敷设方式,牵引供电接触网的导线对地高度较大,雷击跳闸率较高,必须采取有效措施加以解决.建立了接触网的雷电过电压计算模型,并基于矢量匹配技术和网络综合理论提取了高架桥冲击阻抗的等值电路;计算分析了接触网雷击跳闸的概率和特点.结果表明:接触网F线的雷击跳闸率很高,而受到F线屏蔽的T线雷击跳闸率较低;提出了将PW线兼做避雷线使用以及在F线绝缘子上安装带串联间隙避雷器的防护方案,同时,建议加强高架桥非预应力结构钢筋与接地钢筋的可靠等电位连接,以提高防护方案的效果.%Because viaducts are widely adopted in china high-speed railway system, the conductors of traction power supply catenary are high, which makes the catenary suffer from lightning frequently. The paper gives a solution to the problem. Firstly, lightning overvoltage calculation models of the catenary were built, where the impulse grounding impedance equivalent circuit of the viaduct was extracted based on the Vector Fitting Method and Electric Network Theory. Secondly, the probability and characteristics of lightning outage of the catenary were analyzed, and the result shows that the probability of lightning outage of F wire is higher than T wire because T wire is shielded by F wire. Thirdly, two protection measures were proposed, One measure is to use PW wire as lightning shield wire and the other one is to install surge arresters with series gap on the insulators of F wire. Finally, it is also suggested that the equipotential connection of non-prestressed and grounding steels of the viaduct should be encouraged for getting better protection effect.

    A minimum-time algorithm can be used to generate realistic highway routes between specific origins and destinations. Minimizing distances on links will not produce realistic railroad routes if links bear any resemblance to physical trackage. There are also multiple routes between two points since each carrier has its own philosophy. This paper outlines a systematic method of preparing information such that a computer algorithm can generate realistic routes for single- or multiple-carrier movements.

  10. Application of a catenary PBPK model to predict the disposition of "catch and release" anti-PCSK9 antibodies.

    Science.gov (United States)

    Glassman, Patrick M; Balthasar, Joseph P

    2016-05-30

    The development of 'catch and release', or pH-sensitive, monoclonal antibodies (mAb) has become of interest to groups seeking to reduce the influence of target-mediated elimination on pharmacokinetics and pharmacodynamics. In this work, a catenary physiologically-based pharmacokinetic (PBPK) model is described to predict the pharmacokinetic benefit conferred by engineering mAbs for 'catch and release' binding. Our previously published PBPK model was adapted for consideration of the production and elimination of proprotein convertase subtilisin/kexin type 9 (PCSK9) in mice, and the model was then applied to predict the pharmacokinetics of anti-PCSK9 mAb with pH-stable (J10) and pH-sensitive binding (J17). The model was able to generate reasonable predictions of both J10 and J17 plasma pharmacokinetics. For J10, mean (±standard deviation) predicted vs. observed areas under the plasma concentration curve (AUCinf) were: 217 (77.1) vs. 103nMday (1mg/kg), 1.14×10(3) (858) vs. 769nMday (3mg/kg), and 6.60×10(3) (5.58×10(3)) vs. 2.86×10(3)nMday (10mg/kg), and for J17 the values were: 838 (161) vs. 818nMday (1mg/kg), 2.30×10(3) (441) vs. 2.57×10(3)nMday (3mg/kg), and 8.42×10(3) (1.50×10(3)) vs. 9.17×10(3)nMday (10mg/kg). Further simulations with the model predicted that target turnover and the magnitude of change in the complex dissociation rate constant between pH 7.4 and pH 6.0 are key determinants of the improvements in pharmacokinetics associated with 'catch and release' mAbs. The model described here may be useful for prediction of the pharmacokinetics of 'catch and release' mAbs directed against other targets. PMID:27041125

  14. Dynamic assessment of existing soft catenary systems using modal analysis to explore higher train velocities: a case study of a Norwegian contact line system

    Science.gov (United States)

    Rønnquist, Anders; Nåvik, Petter

    2015-06-01

    Significant advances made on the rolling stock have considerably increased the possibility of higher speeds in existing railways. Thus, it is important to explore higher speeds and potential limiting factors of existing soft catenary systems. The present paper investigates procedures to assess the dynamic behaviour of these systems using response sampling and modal analysis. The assessment evaluates and quantifies dynamic response along the section. To verify the approach, a case study is conducted and the following assessment methods are used: lengthwise track correlation estimating dynamic predictability, power spectral density estimations before and after passage and short-time Fourier transforms and spectrograms. The combination provides detailed information on the dynamic behaviour. The first part introduces necessary considerations for suggested modal analysis. The second part describes an existing Norwegian section. The case study is conducted using a finite element model including a straight and a given section between Oslo-Trondheim, providing detailed evaluations and system limitation detections.

  17. Heavy Metal Pollution in Soils on Railroad Side of Zhengzhou-Putian Section of Longxi-Haizhou Railroad, China

    Institute of Scientific and Technical Information of China (English)

    MA Jian-Hua; CHU Chun-Jie; LI Jian; SONG Bo

    2009-01-01

    The pollution status and horizontal distribution of heavy metals (Ni, Pb, Cr, Zn, Cu, and Cd) in the soil on railroad side along the Zhengzhou-Putian section of Longxi-Haizhou Railroad were studied by collecting soil samples along a sampling section perpendicular to the railroad at the distances of 0, 10, 20, 30, 50, 100, 200, 300, and 500 m from the railroad edge. The concentrations of heavy metals in the sampling soils were higher than those of the control site. The concentrations of Pb, Zn, and Cd were found to be the highest in the soils at the railroad edge, and then decreased with increasing distance from the railroad. The highest concentrations of Ni, Cr, and Cu in soils were located at about 10-30 m from the railroad. Compared with the single factor pollution index (SFPI) of heavy metals calculated for the control site, the average SFPI from the sampling sites decreased in the order of Cr > Cd > Pb > Zn > Ni > Cu. There were notable negative correlations between the integral pollution index (IPI) of soil heavy metals at all sampling sites and the distances from the railroad. According to three IPIs calculated from the background values of heavy metals in och-aquic Cambisols, the heavy metal concentrations in the control soil, and the 2nd levels for soil heavy metals in GB15618-1995, the study area could be divided, based on the distances from the railroad, into four pollution zones: heavy pollution zone (0-10 m), medium pollution zone (10-50 m), slight pollution zone (50-100 m), and warning zone (100-500 m), respectively.

    Research purposes: The relation between the catenary and pantograph of high - speed railway directly influences the railway operation safety. The catenary and pantograph interact each other via the contact wire and registration arm, so their dynamic and static positions and interaction force are crucial to the function of the catenary and pantograph. The deep researches were done on the slope of registration arm, the catenary staggers in straight line and curve, the first dropper position and the relations among them for providing the reference to the optimal design of the catenary of high - speed railway. Research conclusions: (1) The slope of registration arm relates to the contact wire tension, the first dropper position, the stagger, the span length, the weights of registration arm and clamp, the curve radius and the superelevation of outer rail. (2) From the research presented in this paper, it is concluded when the other main parameters of the catenary are constant, the slope of registration arm of the catenary of 300 km/h or above high - speed railway is not less than 8 degree in straight line section, and in the curve section the slope is not less than 6 degree and the maximum slope is not bigger than 16 degree. (3)To guarantee a good slope of the registration arm, the catenary stagger is 00 mm in both sections of straight line and curve with large radius, and the distance from the first dropper to the registration point is 5 meter. It can be as the reference to the similar works.%研究目的:高速铁路接触网与受电弓关系直接影响到运营安全.接触网是通过接触线和定位器与受电弓相互作用,它们的动静态空间位置、相互作用力是确保弓网性能的关键.本文对定位器坡度、接触网在直线和曲线的拉出值、第一吊弦点位置设置及之间的相互关系进行详细研究,为高铁接触网设计优化提供参考.研究结论:(1)定位器坡度与导线张力、第一吊弦点位置

    In order to provide theoretical foundation for on-line monitoring of catenary, the static response of ice-coated catenary was investigated. First, a six-span automatic tensioned simple catenary finite element model was built via ANSYS, the static response of ice-coated catenary was conducted with different ice thicknesses, sag variations and end anchorage displacements of contact and messenger wire with different ice thickness were obtained. Then a 1/50 scale model of six-span catenary was constructed based on the similarity theory. End anchorage displacements of contact and messenger wire with diverse ice thicknesses were achieved through small-scale model test. Comparison of the displacements between small-scale model test and finite element simulation validated the feasibility of small-scale model. The results were converted to real catenary, which were compared with simulation results of real catenary, confirmed the correctness of the small-scale model. This small-scale model offers a basis for further research of catenary characteristics.%为了为接触网覆冰的在线监测提供理论基础,对覆冰后接触网的静态响应进行研究。首先,利用ANSYS建立6跨张力自动补偿的简单链型悬挂接触网的有限元模型,对不同覆冰厚度时的接触网的静态响应进行仿真分析,得到随覆冰厚度的变化的接触线和承力索的弛度变化以及下锚处位移。然后,基于相似理论建立1/50的6跨接触网小比例模型。通过模型试验得到不同厚度下接触线和承力索的下锚处位移,对比小比例模型的仿真和试验结果验证了小比例模型的可用性。将模型试验结果推广到实际接触网,对比推广后的试验结果和实际接触网的仿真结果,进一步验证了小比例模型的正确性。该小比例模型可为深入研究接触网特性试验提供试验基础。

    2001-01-01

    Full Text Available Since 1970 and especially since railroad deregulation in 1980, there has been a proliferation of hundreds of new short line rail companies. These railroads range in length from about a mile to more than a thousand miles (those over 350 miles are called “regionals”. They were mainly formed when major Class 1 rail systems spun off marginal trackage. This paperdiscusses the reasons for the short line renaissance.

    The United States railroad industry plays a key role in transporting materials to support our industrial economy. One of the oldest industries in the US, the railroads have developed over 150 years into their present physical and operational configuration. Energy conservation proposals to change industry facilities, equipment, or operating practices must be evaluated in terms of their cost impact. A current, comprehensive and accurate data baseline of railroad economic activity and energy consumption is presented. Descriptions of the history of railroad construction in the US and current equipment, facilities, and operation practices follow. Economic models that relate cost and energy of railroad service to the volume of railroad output and to physical and operational parameters are provided. The analyses and descriptions should provide not only an analytical baseline for evaluating the impact of proposed conservation measures, but they should also provide a measure of understanding of the system and its operations to analysts and policy makers who are involved in proposing, analyzing, and implementing such changes.

  9. The Blue Comet: A Railroad's Astronomical Heritage

    Science.gov (United States)

    Rumstay, Kenneth S.

    2009-01-01

    Between 1929 February 21 and 1941 September 27, the Central New Jersey Railroad operated a luxury passenger train between Jersey City and Atlantic City. Named The Blue Comet, the locomotive, tender, and coaches sported a unique royal blue paint scheme designed to evoke images of celestial bodies speeding through space. Inside each car were etched window panes and lampshades featuring stars and comets. And each coach sported the name of a famous comet on its side; these comets were of course named for their discoverers. Some of the astronomers honored in this unique fashion remain famous to this day, or at least their comets do. The names D'Arrest, Barnard, Encke, Faye, Giacobini, Halley, Olbers, Temple, Tuttle, and Westphal are familiar ones. But Biela, Brorsen, deVico, Spitaler, and Winnecke have now largely faded into obscurity; their stories are recounted here. Although more than sixty years have elapsed since its last run, The Blue Comet, perhaps the most famous passenger train in American history, lives on in the memories of millions of passengers and railfans. This famous train returned to the attention of millions of television viewers on the evening of 2007 June 3, in an episode of the HBO series The Sopranos. This work was supported by a faculty development grant from Valdosta State University.

  12. Compatibility of radioactive materials transportation with railroad operations: two views

    International Nuclear Information System (INIS)

    The nuclear industry has a growing need for safe, economical and efficient transport of nuclear spent fuel and similar radioactive materials. In most cases railroads are the clearly economic mode of transport. Many US rail carriers have shown an increasing reluctance - in some instances an outright refusal - to handle these commodities. This is in spite of very stringent packaging and safety regulations, and a virtually perfect accident record to date. Following several years of fruitless discussions with the railroads on this issue, the nuclear industry filed several complaints with the Interstate Commerce Commission seeking to force the railroads to handle this traffic in normal operations. The history and results of the investigations stemming from these complaints are covered in other papers. The testimony, exhibits and briefs submitted in these cases illustrate the reasons for the railroads' safety concerns and why they believe certain train operating restrictions will produce a safer transport environment. Despite the acknowledged sturdiness of spent fuel casks, the rail industry has not been convinced that the tests and model simulations used by the nuclear industry to design and certify casks adequately portrayed the forces actually generated in a railroad accident. The most significant of the operating changes proposed by the carriers in response to this concern was the requirement that spent fuel be moved only in special trains.According to the railroads, this would permit closer monitoring; reduce both the probability and consequences of accidents; permit better control of speeds; and minimize switching and terminal handling. A review of the material submitted by both the protestants and respondents in these proceedings provides a clearer understanding of the litigants' respective positions, as well as some insights into practical railroading as it pertains to the transportation of nuclear materials

  13. GIS for Nevada railroads: 1993 report

    International Nuclear Information System (INIS)

    This is an interim report on a task within a large, ongoing study by the University of Nevada, Reno to examine the safety of Nevada railroads. The overall goal, of which this year's research is a middle stage, is to develop models based on the use of geographic information systems (GIS). These models are to enable the selection of the best and safest railway routes for the transport of high-level nuclear waste across Nevada to the proposed repository at Yucca Mountain. Last year's research concluded that the databases are adequate and that GIS are feasible and desirable for displaying the multi-layered data required to reach decisions about safety. It developed several database layers. This report deals with work during 1993 on the use of geographic information systems (GIS) for rail-route selection. The goal was to identify and assemble many of the databases necessary for the models. In particular, the research aimed to identify (a) any problems with developing database layers; and (b) the level of effort required. This year's effort developed database layers for two Nevada counties: Clark and Lincoln. The layers dealt with: topographic information, geologic information, and land ownership. These are among the most important database layers. The database layers were successfully created. No significant problems arose in developing them. The level of effort did not exceed the expected level. The most effective approach is by means of digital, shaded relief maps. (Sample maps appear in plates.) Therefore, future database development will be straightforward. Research may proceed on the full development of shaded relief elevation maps for Elko, White Pine, Nye and Eureka counties and with actual modeling for the selection of a route or routes between the UP/SP line in northern Nevada and Yucca Mountain

    1998-07-01

    This paper presents SISMO, the system developed by PETROBRAS and Chemtech for the acquisition of Meteorological and Oceanographic data during the experiment involving the first steel catenary riser (SCR) that will be installed in P-18, one of the most important platforms on the Marlim Oil Field, Campos Basin, Rio de Janeiro. In the near future, PETROBRAS intends to use this new class of risers to replace the presently used flexible risers, that are much more expensive. The information obtained with this first experiment will be used for the development of a design procedure for the future SCR. SISMO was developed in order to allow a non assisted operation and the remote communication between PETROBRAS R and D Center (CENPES) and the meteorological and ooceanographic equipment installed in the platform. It was also designed and developed to be integrated with other acquisition systemsinvolved in the SCR experiment. Completely object oriented programmed, SISMO was developed to run a Windows NT environment and to communicate with the following equipment: meteorological sensors (wind, pressure, temperature and humidity), wave sensors installed on the platform and on an oceanographic buoy and an acoustic Doppler current profiler (ADCP).

  15. Handbook for preservation of local railroad service. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Patton, E.P.; Langley, C.J. Jr.

    1977-01-01

    Throughout the United States, there is an accelerating abandonment of redundant and/or unprofitable light-density railroad lines. This abandonment can be economically harmful to both the shippers and the communities that were previously served. Although greater dependence upon truck transportation is a viable alternative in many cases, other situations indicate that the greatest priority should be attached to preserving some form of local railroad service. The objective of this research was to develop a handbook to assist shippers, local and state governments, and rail planners when their Class I rail service is scheduled for abandonment. Two major options are detailed in the handbook. The first regards innovative procedures which may be used by local groups in attempting to preserve service by the existing Class I carrier. The second approach considers the alternative of operating the particular line as an independent railroad.

  16. INTERLINE, a railroad routing model: program description and user's manual

    International Nuclear Information System (INIS)

    INTERLINE is an interactive computer program that finds likely routes for shipments over the US railroad system. It is based on a shortest path algorithm modified both to reflect the nature of railroad company operations and to accommodate computer resource limitations in dealing with a large transportation network. The first section of the report discusses the nature of railroad operations and routing practices in the United States, including the tendency to concentrate traffic on a limited number of mainlines, the competition for traffic by different companies operating in the same corridors, and the tendency of originating carriers to retain traffic on their systems before transferring it to terminating carriers. The theoretical foundation and operation of shortest path algorithms are described, as well as the techniques used to simulate actual operating practices within this framework. The second section is a user's guide that describes the program operation and data structures, program features, and user access. 11 refs., 11 figs

    The Energy Conservation Projects to benefit the railroad industry using the Norfolk Southern Company as a model for the railroad industry has five unique tasks which are in areas of importance within the rail industry, and specifically in the area of energy conservation. The NIU Engineering and Technology research team looked at five significant areas in which research and development work can provide unique solutions to the railroad industry in energy the conservation. (1) Alternate Fuels - An examination of various blends of bio-based diesel fuels for the railroad industry, using Norfolk Southern as a model for the industry. The team determined that bio-diesel fuel is a suitable alternative to using straight diesel fuel, however, the cost and availability across the country varies to a great extent. (2) Utilization of fuel cells for locomotive power systems - While the application of the fuel cell has been successfully demonstrated in the passenger car, this is a very advanced topic for the railroad industry. There are many safety and power issues that the research team examined. (3) Thermal and emission reduction for current large scale diesel engines - The current locomotive system generates large amount of heat through engine cooling and heat dissipation when the traction motors are used to decelerate the train. The research team evaluated thermal management systems to efficiently deal with large thermal loads developed by the operating engines. (4) Use of Composite and Exotic Replacement Materials - Research team redesigned various components using new materials, coatings, and processes to provide the needed protection. Through design, analysis, and testing, new parts that can withstand the hostile environments were developed. (5) Tribology Applications - Identification of tribology issues in the Railroad industry which play a significant role in the improvement of energy usage. Research team analyzed and developed solutions which resulted in friction

  2. Development of university-industry partnerships in railroad engineering education

    Science.gov (United States)

    Lautala, Pasi T.

    Rail transportation has been an important part of the North American transportation network since the 19th century and it continues to be a major contributor to the economic well-being and the global competitiveness of the U.S. The recent expansion in freight rail volumes and forecasts for continuous growth, together with more favorable attitudes for urban passenger rail present several challenges for the rail industry. One of the challenges is the availability of a well educated engineering workforce. The rail industry has recognized a need to attract new railroad professionals from various disciplines for management and technical positions, but most universities eliminated railroad engineering from their curricula after the recruitment levels faded several decades ago. Today, railroad expertise and related engineering courses exist at only a few universities and most students graduate without any exposure to rail topics. While industry representatives have expressed their concern about a future workforce, little data is available on the extent of the demand, on the characteristics and skills of preferred candidates, and on the role that universities can play. A benchmarking study was undertaken to investigate the demand for university engineering graduates and assess whether current methods are sufficient to attract, educate, recruit, train and retain engineering students in the railroad profession. Data was collected from industry human resources and training managers to define the quantitative and qualitative needs for railroad engineers. In addition, recently hired engineers working in the rail industry were surveyed to determine the extent of their university exposure in rail topics and how it affected their career choice. The surveys indicated an increase of over 300 percent in the annual recruitment for railroad engineers by the participating companies between 2002 and 2005. Recruitment levels are expected to remain high for the next five to ten years due

    接触网既是供电的线路,又是受电弓的滑道,其结构为三维柔性索网,当受电弓通过时,支持点和张力补偿点不存在瞬时大位移,其动态行为可以忽略,定位点由于存在非线性铰接,定位点处的动态行为不能被忽略。为等效定位点的动态行为,通过静力学分析,简化三维力学模型,将定位装置的三维非线性铰接等效为二维线性弹簧,并推导弹簧的等效刚度值计算公式,得到接触网二维力学模型。最后通过仿真实例,验证接触网二维力学模型的静态和动态效果与接触网三维模型完全吻合,并确认定位装置等效刚度的计算方法。%The catenary serves for power supply and as a path for pantograph sliding, When a pantograph is passing by, there is no large instant displacement at the support points and the tension compensation points, therefore the dynamic behavior can be ignored on account of its three-dimensional soft wire structure . However, the dynamic behavior at the fixing points cannot be ignored because of the non-linear hinge. To obtain the equivalent dynamic behavior of the fixing points, the three-dimensional mechanical model is simplified by static analysis, which converts the three-dimensional nonlinear hinge into a two-dimensional linear spring, and then the formula to calculate equivalent stiffness of the spring is derived and the two-dimensional mechanical model of the catenary is established. Finally, the static and dynamic effects of the two-dimensional mechanical model of the catenary are proved with simulation in full agreement with that of the three-dimensional mechanical model of the catenary, and the method to calculate the equivalent stiffness of the steady device is confirmed.

  16. Development of university-industry partnerships in railroad engineering education

    Science.gov (United States)

    Lautala, Pasi T.

    Rail transportation has been an important part of the North American transportation network since the 19th century and it continues to be a major contributor to the economic well-being and the global competitiveness of the U.S. The recent expansion in freight rail volumes and forecasts for continuous growth, together with more favorable attitudes for urban passenger rail present several challenges for the rail industry. One of the challenges is the availability of a well educated engineering workforce. The rail industry has recognized a need to attract new railroad professionals from various disciplines for management and technical positions, but most universities eliminated railroad engineering from their curricula after the recruitment levels faded several decades ago. Today, railroad expertise and related engineering courses exist at only a few universities and most students graduate without any exposure to rail topics. While industry representatives have expressed their concern about a future workforce, little data is available on the extent of the demand, on the characteristics and skills of preferred candidates, and on the role that universities can play. A benchmarking study was undertaken to investigate the demand for university engineering graduates and assess whether current methods are sufficient to attract, educate, recruit, train and retain engineering students in the railroad profession. Data was collected from industry human resources and training managers to define the quantitative and qualitative needs for railroad engineers. In addition, recently hired engineers working in the rail industry were surveyed to determine the extent of their university exposure in rail topics and how it affected their career choice. The surveys indicated an increase of over 300 percent in the annual recruitment for railroad engineers by the participating companies between 2002 and 2005. Recruitment levels are expected to remain high for the next five to ten years due

    Severe slugging is an undesirable flow phenomenon for a pipline-riser system with the gas-liquid mixture transportation in ocean engineering. In present paper experiments were performed for the two-phase flow characteristics in a horizontal/declination pipeline-catenary riser system with the gas-liquid mixture transportation, and flow patterns were identified by series combinations of gas and liquid superficial velocities, including severe slug, intermittent and oscillation flows. The formation mechanisms of these flow patterns were presented and the conditions where the severe slug flow can be produced in the catenary riser were obtained. The results show that the severe slug flow in a catenary riser has remarkably periodic characteristics and consists of four stages in a circle, including slug formation, slug production, slug blowout and liquid fallback, respectively, where the characteristics of the flow parameters in each stage were given. Moreover, the formation mechanisms of severe slug flows in both catenary and vertical risers were compared and analyzed, and a remarkable differenti- ation in the slug formation stages for the two types of risers was observed, where the formation procedure of a mixture liquid slug with both gas and liquid first occurs before the pure liquid slug in the catenary riser can be produced, however, there is no occurrence of such a procedure of the mixture liquid slug for the vertical riser.%严重段塞流是海洋工程气液混输管线-立管系统中常见的一种特殊有害流动现象,采用水平-下倾-悬链线立管气液混输组合管道系统,通过系列实验在悬链线立管中获得了严重段塞流、间歇流和震荡流等流型,阐述了这些流动现象的形成机理,提出了能够产生严重段塞流的判定准则.结果表明,悬链线立管严重段塞流具有明显周期性,在一个周期内的流动特征可分为液塞形成、液体出流、液气喷发及液体回流等4个阶段,进而给

    Currently, in the railroad industry, the lack of electrical sources in freight cars is a problem that has yet to find practical solutions. Although the locomotive generates electricity to power the traction motors and all the equipment required to operate the train, the electrical power cannot, in a practical manner, be carried out along the length of the train, leaving freight cars unpowered. While this has not been a major issue in the past, there is a strong interest in equipping modern ca...

  20. Railroading technique of dermal grafting for linear atrophic scarring

    2014-01-01

    Full Text Available Dermal grafting is a valuable technique in the field of dermatosurgery for the treatment of atrophic scars where the source of filler material is the patient′s own dermis. However, it is underused for the reasons being difficulties in placing the graft in the tunnel, keratin cysts and complications due to biofilms. Railroading technique used in urology for rupture urethra has been described for dermal grafts to overcome the technical difficulties of graft placement.

  1. Diesel exhaust exposure in the Canadian railroad work environment.

    2003-01-01

    An investigation of occupational exposure to diesel exhaust, in terms of elemental carbon, was conducted as part of a feasibility study in the Canadian railroad industry. Both personal and area samples were collected from three major operating divisions of the railways: mechanical service, transportation, and engineering. A total of 255 elemental carbon samples have been described. The results show that all but six elemental carbon concentrations, expressed as size-selective respirable air samples taken using a 10 mm nylon cyclone, are well below the 2001 proposed American Conference of Governmental Industrial Hygienists' (ACGIH) threshold limit value (TLV) of 20 microg/m3. The concentration of diesel exhaust, expressed as elemental carbon, in the railroad industry is much lower than that in some other major industries such as mining and forklift truck operations. If the TLV is to be applicable to a broad range of workplace settings such as railroad, construction, and mining, the use of a TLV that is based on an elemental carbon measurement of size selective respirable samples, as recommended in the 2001 ACGIH proposal, would appear to be the most valid strategy for control of exposure to diesel exhaust.

    Due to hundreds of fatalities annually at unprotected railroad crossings (mostly because of collisions with passenger vehicles and derailments resulting from improperly maintained tracks and mechanical failures), supplying a reliable source of electrical energy to power crossing lights and distributed sensor networks is essential to improve safety. With regard to the high cost of electrical infrastructure for railroad crossings in remote areas and the lack of reliability and robustness of solar and wind energy solutions, development of alternative energy harvesting devices is of interest. In this paper, improvements to a mechanical energy harvesting device are presented. The device scavenges electrical energy from deflection of railroad track due to passing railcar traffic. It is mounted to and spans two rail ties and converts and magnifies the track's entire upward and downward displacement into rotational motion of a PMDC generator. The major improvements to the new prototype include: harvesting power from upward displacement in addition to downward, changing the gearing and generator in order to maximize power production capacity for the same shaft speed, and improving the way the system is stabilized for minimizing lost motion. The improved prototype was built, and simulations and tests were conducted to quantify the effects of the improvements.

    Little is known about the extent and forces of urban path dependence in developing countries.  Railroad construction in colonial Kenya provides a natural experiment to study the emergence and persistence of this spatial equilibrium.  Using new data at a fine spatial level over one century shows that colonial railroads causally determined the location of European settlers, which in turn decided the location of the main cities of the country at independence.  Railroads declined and settlers lef...

    Two reform acts, the Staggers Railroad Act of 1980 and the Railroad Revitalization and Regulatory Reform Act of 1976, represented big changes in U.S. policy toward railroads. An important welfare gain from these changes predicted by researchers was the efficiency gain from increased densities in rail freight traffic. However, few retrospective studies have analyzed the accuracy of these predictions. The present paper fills this gap by analyzing the effects of regulatory changes on freight tra...

    1990-05-01

    Oil was first discovered in Railroad Valley, south-central Nevada in 1954. Since that time, over 195 wells have been drilled and six oil fields have been found: Bacon Flat, Currant, Trap Spring, Eagle Springs, Grant Canyon and Kate Spring. Two wells in the Grant Canyon field had flows between 2,480 and 4,108 bbl/day in 1987 and may be the most prolific wells onshore in the continental US. Production in the Railroad Valley fields is from Oligocene volcanic and sedimentary rocks and Paleozoic carbonate formations. Traps are structural or structural and stratigraphic, and reservoir seals are indurated or clayey valley fill, weathered tuff, and shales in Tertiary sediments. Reservoir temperatures range between 95 and 309{degree}F. Previous workers have identified a statistically significant positive correlation between hydrocarbon microseepage and vegetation anomalies over the Railroad Valley oil fields with Landsat Multispectral Scanner (MSS) imagery. Several flight lines of high spectral and spatial resolution imagery in the visible, near infrared, shortwave infrared, and thermal infrared regions of the spectrum were flown with Geoscan's MkII Airborne Multispectral Scanner to determine if there was a mineralogical signature associated with the oil fields. The 24-channel scanner collected 8-m resolution picture elements over a swath of about 8 km. Image processing strategies were developed from a knowledge of the spectral curves of minerals in the laboratory. The results from processing Geoscans MkII data were also compared with those obtained from processing Landsat Thematic Mapper (TM) imagery over the same area. An 8 {times} 6 km carbonate and iron anomaly was detected on the processed MkII imagery over the Trap Spring oil field. This anomaly may be related to hot spring activity, reported by other workers, that has formed extensive calcite deposits along faults.

    Full Text Available This paper presents an empirical investigation to study the relationship between emotional intelligence and job performance in railroad industry. The study uses two questionnaires, one for measuring emotional intelligence adopted from Salovey and Mayer (1989 [Salovey, P., & Mayer, J. D. (1989. Emotional intelligence. Imagination, Cognition and Personality, 9(3, 185-211.] and the other one for measuring job performance. The study selects 300 full time employees who work for railroad industry in city of Tehran, Iran, distributes two questionnaires among the employees and managed to collect all filled ones. Using Spearman correlation, the study has determined a positive and meaningful relationship between emotional intelligence and job performance (r = 0.796, Sig. = 0.000. In addition, there were positive and meaningful relationships between four components of emotional intelligence, namely consciousness (r = 0.642, Sig. = 0.000, self-regulation (r = 0.41, Sig. = 0.000, self-awareness ( r = 0.552, Sig. = 0.000 and social skills (r = 0.524, Sig. = 0.000.

  10. Prevention of damage to highways and railroads in mining areas

    International Nuclear Information System (INIS)

    Roads and railways, a distinctive part of Civil Engineering, when situated in subsidence areas, are subjected to the multiparameter reactions of soil due to subgrade deformation. The essence of technical degradation of such objects due to mining-induced subsidence entail changes in their functional and stability-strength properties. These changes take place within the structural system itself and, also in its subgrade. The linear character of such objects as a highway or a railroad creates a specific type of interaction between the subgrade and the elongated structure. The type of mining-induced contact reactions and the magnitude of service loads determine the operating capability of structures under these specific conditions. The need to maintain the proper geometrical parameters of the system (grade line, slope, superelevation, horizontal and/or vertical curvatures) arises from the necessity to maintain safe and uninterrupted traffic. The paper is based primarily on the author's broad and lengthy research experience

  11. Port wine landscape: railroads, phylloxera, and agricultural science.

    Science.gov (United States)

    Macedo, Marta

    2011-01-01

    It is easy to understand why regions that produce very fine goods such as port wine tend to conceal technological and scientific inputs and praise the uniqueness of the terroir. This paper suggests that, during the last decades of the nineteenth century, viticulture in the Douro region of Portugal was as much a product of soil, local farming traditions, and individual entrepreneurship as it was of modern state science and national politics for agricultural improvement. the unprecedented public projects of building a railroad and fighting phylloxera permanently changed the land of port wine. Moreover, those engineering practices of rationalization, simplification, and standardization that were inscribed on Douro's landscape proved essential for the Portuguese experience of modernization and nation-building.

    2008-01-01

    The Underground Railroad is commonly understood as a defining moment in the ideology of the Canadian state regarding the legacy of racism and anti-racism. This paper attempts to recast the narrative of the Underground Railroad through the lens of an anti-imperialist, anti-racist political economy, departing from the view of Canada’s anti-racist rescue of fugitive slaves from racist America. The Underground Railroad was in fact the product primarily of the struggle for self-emancipation of Ame...

  13. Wireless Power Transfer for High-precision Position Detection of Railroad Vehicles

    CERN Document Server

    Ryu, Hyun-Gyu

    2015-01-01

    Detection of vehicle position is critical for successful operation of intelligent transportation system. In case of railroad transportation systems, position information of railroad vehicles can be detected by GPS, track circuits, and so on. In this paper, position detection based on tags onto sleepers of the track is investigated. Position information stored in the tags is read by a reader placed at the bottom of running railroad vehicle. Due to limited capacity of battery or its alternative in the tags, power required for transmission of position information to the reader is harvested by the tags from the power wirelessly transferred from the reader. Basic mechanism in wireless power transfer is magnetic induction and power transfer efficiency according to the relative location of the reader to a tag is discussed with simulation results. Since power transfer efficiency is significantly affected by the ferromagnetic material (steel) at the bottom of the railroad vehicle and the track, magnetic beam shaping b...

  20. Energy study of railroad freight transportation. Volume 3. Regulation and tariff

    Energy Technology Data Exchange (ETDEWEB)

    None

    1979-08-01

    Volume 1 described the history of the railroad industry and pointed out that the number of separate companies, their monopoly power, and their trade and labor practices invited regulation by outsiders from the early days. Even though new regulations have been added over the years, few have been removed. Tariffs have been modified to fit a number of needs, not all of them economic. The effects of government regulation on the energy efficiency of railroad operations are examined. The development of railroad regulation is examined and the governmental legislation, policies, and procedures that make up the regulatory environment within which the railroads must operate are briefly described. The relationship among regulations, energy usage, and costs in three specific areas of regulation: long-haul rates, empty car distribution, and rates on low-density rail traffic are examined.

  4. The impact of the railroad on American society: a communication perspective of technology

    Directory of Open Access Journals (Sweden)

    Matusitz, Jonathan

    2009-10-01

    Full Text Available This manuscript examines the railroad system as a combination of humans and machines that form a symbiosis, and explains how the railroad exerted a huge effect on American life when it made irrelevant the organic – following nature – time system that existed in cities and countries where clocks were set according to weather conditions. The author makes the point that the railroad is an organ of society, that it will evolve to serve the functions we demand, that it has molded and altered – but never replaced – contact between humans, and that it will continue to enhance and facilitate it. This manuscript analyzes the social, cross-cultural, psychological, and financial impact of the railroad on American society in the past two hundred years. The measure of progress in the United States is tantamount to the mass of things that had to be sacrificed to it.

  8. INEQUALITIES RESEARCH OF THE TRACK AT THE RAILROAD CROSSINGS

    Directory of Open Access Journals (Sweden)

    M. B. Kurhan

    2015-08-01

    Full Text Available Purpose. The intersection of highways and railways in one level – railway crossing, is a zone of increased danger for rail and road transport. Nearly half of all crossings are available on the main directions of passenger transportation. From this comes the problem of maintenance and service locations of intersection roads and railways. The purpose of this work is to evaluate the processes of emergence and development of inequalities in the area of railroad crossings and identify the factors that cause them. Methodology. The presence of derogation from the plan and profile within the railway crossing and approaches to it reduces evenness of riding and passenger comfort. Today, there are various possibilities for shooting natural geometry of a railway track. For research on a large number of areas during long service life, the tape of a track measuring car remains the most convenient. However, this tool is directed to assess the state of the railway line and does not determine the exact geometrical position. When trying to determine valid outlines of the track inequalities on track measuring tape, some difficulties arise. Findings. Performed statistical analysis showed a steady trend of growth of inequalities in the area of the railway crossings. Generally, the level of inequalities in the vertical plane increases in1.3−3.2 times and in 1.2−2.0 times in the horizontal plane (compared with areas that are outside crossing. During the deflection lines of action in the area of railroad crossing concrete slabs work as ribs that limit deflections of rail-tie grating. When placing the wheels of the bogie before (or after and within crossing the calculated modulus of elasticity under the rail base, brought to the point of wheels contact can vary up to 3 times. Originality. Issues of the assessment and investigation of inequalities on track started to be developed. The resulting statistics on inequalities accumulation gauge in the zone of crossing

To compute the optimal transportation capacity and flow on a certain railroad, specialized decision-support software which is available on the market was used.

  10. Political-Legal Institutions and the Railroad Financing Mix, 1885-1929

    OpenAIRE

    Daniel A. Schiffman

    2001-01-01

    During the 19th Century, U.S. railroads relied primarily on debt issues to finance their growth. This policy contributed to major financial crises, beginning in 1857, 1873 and 1893. Nevertheless, railroads failed to reduce their leverage over 1900-1929, and suffered severe consequences during the Great Depression. In order to explain this puzzle, I focus on several key political-legal developments that originated around 1885. These are: (a) Changes in the bankruptcy process; (b) the emergence...

  12. Ground reaction forces during human locomotion on railroad ballast.

    Science.gov (United States)

    Wade, Chip; Redfern, Mark S

    2007-11-01

    Locomotion over ballast surfaces provides a unique situation for investigating the biomechanics of gait. Although much research has focused on level and sloped walking on a smooth, firm surface in order to understand the common kinematic and kinetic variables associated with human locomotion, the literature currently provides few if any discussions regarding the dynamics of locomotion on surfaces that are either rocky or uneven. The purpose of this study was to investigate a method for using force plates to measure the ground reaction forces (GRFs) during gait on ballast. Ballast is a construction aggregate of unsymmetrical rock used in industry for the purpose of forming track bed on which railway ties are laid or in yards where railroad cars are stored. It is used to facilitate the drainage of water and to create even running surfaces. To construct the experimental ballast surfaces, 31.75 mm (1 1/4 in.) marble ballast at depths of approximately 63.5 mm (2.5 in.) or 101.6 mm (4 in.) were spread over a carpeted vinyl tile walkway specially designed for gait studies. GRF magnitudes and time histories from a force plate were collected under normal smooth surface and under both ballast surface conditions for five subjects. GRF magnitudes and time histories during smooth surface walking were similar to GRF magnitudes and time histories from the two ballast surface conditions. The data presented here demonstrate the feasibility of using a force plate system to expand the scope of biomechanical analyses of locomotion on ballast surfaces. PMID:18089931

  14. THE RAILROAD CAPACITY CRISIS: After Cutting to the Bone and More, Trains Are Back

    Directory of Open Access Journals (Sweden)

    Richard D. Stone

    2008-01-01

    Full Text Available During the Era of Railroad building (primarily the last half of the 19th century, it was far more profitable to lay track than to operate railroads due to the subsidiesfrom various levels ofgovernment and the competition between cities to be located on as many lines as possible, and the overcharging of the railroads by the construction companies. Railroads compensated for this glut by cross-subsidizing the unprofitable branch lines with revenues from the main lines. But as competition from other modes took hold, this was increasingly difficult to do. Therefore, by the early 20th century, railroads began to slowly shed some of the lightly trafficked lines. Regulatory changes in the 1980s made abandonment easier, and wholesale discarding of lines, including former mainlines, became common. But by the turn of the century,foreign imports put a greater demand on rail transportation, and lack of capacity caused many of the remaining lines to become very congested, in turn, causing extensive delays.

    2014-01-01

    The marine environment is changeful .The steel catenary riser is prone to produce fatigue dam-age so as to affect the safety of production on effect of complex marine environmental load .In order to study the dynamic response of the riser under environmental load , the paper built SCR model by use finite element software ABAQUS .By applying displacement boundary condition on the upper suspension point of the riser to simulate the movement of floating body , using the nonlinear spring whose stiffness is based on P-y curve to simulate the riser-soil interaction , adjusting the parameters of environmental load on the ris-er,it studied the influence of floating body motion , wave amplitude , wave period and current velocity on SCR dynamic response .The results show that the steel catenary riser presents different dynamic response with the change of environmental load , the riser is more sensitive to heaving motion of floating body;the larger the wave amplitude ,the less is its period , the larger the dynamic response of the riser on suspen-sion point and touchdown point;with the increase of current speed , the overhanging length gets bigger .%海洋环境变化多端,钢悬链线立管( SCR)在复杂的环境荷载作用下容易发生疲劳破坏而影响安全,为研究立管在环境荷载作用下的动力响应,本文利用ABAQUS有限元软件对SCR建模,在立管上部悬挂点施加位移边界条件模拟浮体的运动,在立管的触地段采用刚度基于P-y曲线的非线性弹簧单元模拟立管与海床的相互作用,并通过调节立管环境荷载参数,研究了浮体运动、波浪振幅、周期和海流速度等参数对钢悬链线立管动力响应的影响。结果表明:钢悬链线立管随着环境荷载参数的变化呈现出不同的动力响应,立管对浮体的垂荡运动更敏感;波浪的振幅越大、周期越小,立管触地点与悬挂点的动力响应越大;海流速度增大,悬垂段长度会变大。

  16. The Trade-Off between Road and Railroad Freight Transport – Cost Benefit Analysis for Slovenia

    Directory of Open Access Journals (Sweden)

    Jure Erjavec

    2014-03-01

    Full Text Available The choice of transportation mode for freight transport has a profound effect on logistics companies, infrastructure providers and society as a whole. The efficiency of freight transport is important because it has a profound effect on several economic and environmental factors. The paper analyses the costs difference between railroad and road freight transport. The stakeholder analysis is used to enable the identification of the interests of various groups. The government is identified as the focal stakeholder. The governmental decision support model that focuses on the Slovenian case of road and railway freight transport is proposed. The proposed model can serve the government with its decision-making process when adopting policies that concern road and railroad transport such as subsidies or increased road tolls in order to promote railroad transport.

    Full Text Available In 1887, in answer to railroad abuses of monopoly power, Congress passed the Interstate Commerce Act, which created the Interstate Commerce Commission (ICC. In the next decade the Commission’s powers were considerably diminished by a series of Supreme Court decisions in cases in which the railroads appealed ICC rulings. In only one case during this period, the United States v. Trans-Missouri Freight Association, did the Court uphold an ICC decision. This case was primarily about collaborative ratemaking in rate bureaus but covered several larger issues, especially the possibly conflicting jurisdictions of the Sherman Act and the Interstate Commerce Act.

  2. Train wrecks to typhoid fever: the development of railroad medicine organizations, 1850-World War I.

    Science.gov (United States)

    Aldrich, M

    2001-01-01

    From their beginning American railroads developed medical arrangements to care for the large number of workers and passengers they killed or injured. After the Civil War, both labor unrest and liability concerns led them to expand and formalize these arrangements, and three forms of organization arose. Western roads, facing an almost complete lack of medical facilities, developed employee-funded hospital organizations. In the east, companies created medical organizations under a salaried chief surgeon and contracted with local physicians to provide care. A third model, pioneered by the Baltimore & Ohio Railroad in the 1880s, devised a beneficial society that provided medical care and compensation for injured workers. Although these organizations involved both contract practice and group hospitalization, the AMA seems to have ignored them. In the 1880s railroad physicians developed their own organizations, including the National Association of Railway Surgeons, in which they discussed problems of professionalization and such medical matters as "railway spine." Concern with costs and labor turnover also led the carriers into preventive medicine. Some roads provided smallpox and typhoid vaccinations, campaigned against malaria, improved passenger-car sanitation, required physical examinations of their employees, and trained them in first aid. By World War I, railroad medical organizations provided care to nearly two million employees and employment to about 10 percent of all physicians. PMID:11423683

  10. Evaluation of the adequacy of maintenance tasks using the failure consequences of railroad vehicles

    International Nuclear Information System (INIS)

    The purpose of this study is to improve the efficiency, reliability and safety related to railroad maintenance tasks through an evaluation of the consequences of failures. The brake system was selected based on the failure data obtained from railroad vehicles in operation as one of the safety systems in railroad vehicles. The failure causes, failure effects, and the criticality of the failure mode were drawn for 62 failure modes of the braking system through the use of an FMECA for the 30 sub-devices having primary functions. The various maintenance tasks for the braking system were categorized into the 62 failure modes and failure consequences using the FMECA and the logic of maintenance decisions. Braking systems manufactured by the same manufacturer and operated by two different operators were studied in an effort to analyze preventive maintenance and to evaluate the adequacy of preventive maintenance tasks for the 62 failure modes. Based on results of the evaluation of these preventive maintenance tasks, new maintenance tasks were proposed, and concrete cost-cutting effects were determined from the calculation of the maintenance time and expected costs, using a preventive maintenance template developed specifically for railroad vehicles

  5. A multi-objective ant colony optimization method applied to switch engine scheduling in railroad yards

    Directory of Open Access Journals (Sweden)

    Jodelson A. Sabino

    2010-08-01

    Full Text Available This paper proposes an ant colony optimization algorithm to assist railroad yard operational planning staff in their daily tasks. The proposed algorithm tries to minimize a multi-objective function that considers both fixed and variable transportation costs involved in moving railroad cars within the railroad yard area. This is accomplished by searching the best switch engine schedule for a given time horizon. As the algorithm was designed for real life application, the solution must be delivered in a predefined processing time and it must be in accordance with railroad yard operational policies. A railroad yard operations simulator was built to produce artificial instances in order to tune the parameters of the algorithm. The project is being developed together with industrial professionals from the Tubarão Railroad Terminal, which is the largest railroad yard in Latin America.Este trabalho propõe um algoritmo de otimização com colônia de formigas para auxiliar a equipe de planejamento de operações de pátios ferroviários em suas tarefas diárias. O algoritmo proposto é baseado em uma função multi-objetivo que busca a redução dos custos fixo e variável de movimentação de vagões no pátio. Isto é feito através da busca da melhor programação para as locomotivas de manobra, considerando um dado horizonte de planejamento. Como o algoritmo foi desenvolvido para aplicação na vida real, a solução deve ser entregue em um tempo de processamento definido previamente e deve obedecer as políticas operacionais do pátio. Foi desenvolvido um simulador de operações de pátio que gera instâncias artificiais utilizadas para ajuste dos parâmetros do algoritmo. O projeto está sendo desenvolvido em conjunto com profissionais envolvidos na operação do Terminal Ferroviário de Tubarão, o qual é o maior pátio de manobras da América Latina.

  6. Preliminary characterization of the F-Area Railroad Crosstie Pile at the Savannah River Site

    Energy Technology Data Exchange (ETDEWEB)

    1991-10-01

    Historical information about the F-Area Railroad Crosstie Pile is limited. The unit is believed to have been a borrow area for earth fill that began receiving railroad crossties during the 1960s. The number of crossties at the unit began to increase significantly in 1984 when major repair of the SRS rail system was initiated. An estimated 100,000 used railroad crossties have accumulated at the unit since 1984. In an effort to determine the impact of the railroad crossties on the environment a total of 28 soil samples were collected from four test borings in March of 1991. Sample depths ranged from ground surface to 21.5 feet. Three of the borings were extended to the water table and groundwater samples were collected, one in an upgradient background'' area, and two downgradient from the unit. Few analytes were reported above detection limits. Test results are summarized in Section 4.0 and analytes not detected are summarized in Appendix A to this report. In three soil samples collected from depths between 10 and 21.5 feet, copper occurred at levels slightly above background. These copper values were detected in the sidegradient test boring and in the two downgradient test borings. Three organic analytes, acetone, pyridine, and Toluene, were reported above detection limits but well below drinking water standards (DWS) in all test borings, including the upgradient boring. Radionuclide activities were reported above background in both soil and water samples from all test borings. There do not appear to be any statistically significant trends in radionuclide activities with depth, or between upgradient or downgradient borings. The analytes detected in the test borings downgradient from the unit cannot be attributed to the railroad crosstie pile as they are not significantly different than the values reported for the upgradient, background test boring.

  7. Railroad perspective on transportation of spent fuel and high level waste and recent ICC decisions

    International Nuclear Information System (INIS)

    This paper attempts to summarize some railroad viewpoints on issues concerning transportation of spent fuel and high-level waste and to outline Interstate Commerce Commission decisions arising over differing opinions about the manner of such transportation. Although the railroad position includes a number of legal arguments, it also involves operating expertise and a number of well-based questions concerning the safety of casks under actual operating conditions in regular trains. The commonly-used estimates of accident frequency and severity in regular trains are severe underestimates based on a mistake in the annual number of railroad car-miles, inadequacies in and misunderstanding of accident reporting, and invalid assumptions, especially concerning fires, which some actual data suggest are far more frequent than assumed. Thus, railroads estimate casks could be involved in at least 12 accidents involving severe fires by 1990. A number of unanswered questions about casks and perceived inadequacies in testing lead to a conservative railroad position. These include the possibility of escape routes of materials other than by breach such as weld and pressure relief valve failures and direct radiation hazards through loss of shielding. These doubts are fostered through experience with accidents more severe than those used in testing or certification as well as these questions. Also, there is doubt concerning the integrity of fuel rod cladding (used as a second level of containment) in credible accident situations. Moreover, the damage estimates of $1,000 per man rem have been shown to have no relationship to damages in a transportation accident.Added safety is expected in special trains for at least 17 reasons involving speed, transit time, routing, train consist, crew alertness, reduced slack and other reduced hazards and accident opportunities

    2008-03-01

    Full Text Available This article presents and analyzes the identity construction process of a rail workers collective of rural origin that was linked to an industrial work environment by the middle of the 20th century in Bogotá. Different ruptures and continuities, as well as the confluence of working tensions and vindications of the rural trajectories, determine the composition of particular memory and identity matters. From collected oral narratives of the laborers, this study shows the most significant elements of day-to-day life around the railroads, its tensions and its encounters.

  2. Study on smart seat technology for railroad vehicles using piezoelectric sensors

    International Nuclear Information System (INIS)

    A study on smart seats for railroad vehicles was conducted using piezoelectric (PZT) sensors. For this purpose, the concept of passenger friendly smart seats was defined, and a PZT sensor was selected as the optimum sensor based on this concept. Using PZT sensors, simulation tests were performed using a sub-scale model railroad vehicle. In these tests, the main functions of the smart seats were extracted and simplified to improve the effectiveness of the simulation tests. Based on the test results, the system for smart seats proposed in this paper was successfully verified using PZT sensors and the dedicated operation software for the system. This paper will contribute to the improvement of services in high-speed rail systems through advances in ticket checking tasks.

  3. Investigation of Key Factors for Accident Severity at Railroad Grade Crossings by Using a Logit Model

    2010-01-01

    Although several studies have used logit or probit models and their variants to fit data of accident severity on roadway segments, few have investigated accident severity at a railroad grade crossing (RGC). Compared to accident risk analysis in terms of accident frequency and severity of a highway system, investigation of the factors contributing to traffic accidents at an RGC may be more complicated because of additional highway–railway interactions. Because the proportional odds assumption ...

  4. Preparedness of hazardous materials emergencies in railyards: Guidance for railroads and adjacent communities

    Energy Technology Data Exchange (ETDEWEB)

    1991-09-01

    Railroads are a key part of the distribution system for hazardous materials and, thus, much hazardous material passes through railyards en route to intermediate or final consumers. While the vast majority of these materials are shipped without incident, both the number of shipments and the nature of the materials themselves dictate that railyards and surrounding communities be prepared to respond quickly and effectively to emergencies. This report contains information on 11 emergency preparedness functions and 150 guidance recommendations.

  5. Data on the acoustic comfort of passengers in railroad cars and soundproofing recommendations

    Science.gov (United States)

    Tomescu, C.; Vrasti, R.

    1974-01-01

    Acoustic passenger comfort in railroad cars is represented by the following values: Total noise level in db, octave sound spectrum in db, and indices of intelligibility. The noise level perceived inside the car results from two components: one due to the penetration of air noise, and another due to the transmission of vibrations through solids. Measurement results show the necessity of improving bogie and bogie-body connections, intensification of soundproofing of the floor, adaption of windows with double panes, etc.

    This thesis took the policy-analysis framework of Marchau and Walker (2005) as a starting point for assessment and valuation of road and railroad noise impacts and its consequences for noise policy. Four research questions were answered. To what extent can international data on noise, often produced by using different national calculation methods, be compared? And what will it mean for (inter)national noise policy? The literature review shows first that noise calculations in different countri...

  7. Predicting routes of radioactive wastes moved on the U.S. railroad system

    International Nuclear Information System (INIS)

    Relative to the use of public roads, railroads offer several advantages for the movement of radioactive wastes. These include the ability to accommodate large, heavy containers, the ability to transfer large volumes in a single movement, and the safety of a dedicated, centrally controlled right-of-way. The principal disadvantage of railroads is that the shipper has considerably less freedom to specify the route a shipment will take. The lower density of the railroad network, the need to coordinate waste shipments with other traffic in the system, and the private ownership of the US network all reduce the shippers routing power. Although the shipper can dictate an exact route, this could require the use of a special train at an increased cost. Before considering the general use of special trains to move radioactive wastes, it is first desirable to determine how these materials would move as general rail traffic. This paper describes the development of a system to predict routes of general rail traffic at Oak Ridge National Laboratory

  8. Predicting routes of radioactive wastes moved on the US railroad system

    International Nuclear Information System (INIS)

    One of the issues to be considered in the analysis of alternative repository sites for nuclear wastes is the pattern of shipments from reactors and other waste sources to the repository. In the United States, regulations and costs make rail shipments the preferred mode for high-level radioactive waste. The railroad network of the United States is owned by approximately 100 corporations that simultaneously compete for traffic and cooperate to move shipments that require carriage by more than one company. Because changing companies usually delays a shipment, there is a tendency to minimize the number of carriers involved in moving it. Moreover, when several carriers are required, the originating company (specified by the shipper) tends to retain the shipment on its portion of the network. These characteristics are nearly unique among the world's rail systems, and they must be recognized in any model of paths of future shipments through the network. This paper describes the development of a rail routing program that can be applied to the movement of radioactive materials throughout the United States. Shipments can be initiated at a specific location on a specific railroad. A route can be generated and displayed on a map of the United States. The particular route generated depends upon the emphasis placed on various classes of rail lines. Demonstration routings illustrate predicted routes of normal freight shipments, the effect of blocking passage through selected cities, and the effect that the existence of independent railroad companies can have on the patterns of shipments

  9. Reconsidering the Underground Railroad: Slavery and Racialization in the Making of the Canadian State

    Directory of Open Access Journals (Sweden)

    Abigail Bakan

    2008-05-01

    Full Text Available The Underground Railroad is commonly understood as a defining moment in the ideology of the Canadian state regarding the legacy of racism and anti-racism. This paper attempts to recast the narrative of the Underground Railroad through the lens of an anti-imperialist, anti-racist political economy, departing from the view of Canada’s anti-racist rescue of fugitive slaves from racist America. The Underground Railroad was in fact the product primarily of the struggle for self-emancipation of American black slaves. The central place of these actors as agents of their own freedom struggle needs to be recognized and restored, taken as a theoretical and historical starting point in explaining the pre-history of Confederation. The British North American colonies served as a safe space for fugitive slaves as a result of realpolitik; racism and a culture of hegemonic whiteness were endemic to the early origins of the Canadian state. This analysis is placed in the context of current and historical discussions of anti-racism and anti-imperialism.

  10. Analysis of railroad tank car releases using a generalized binomial model.

    Science.gov (United States)

    Liu, Xiang; Hong, Yili

    2015-11-01

    The United States is experiencing an unprecedented boom in shale oil production, leading to a dramatic growth in petroleum crude oil traffic by rail. In 2014, U.S. railroads carried over 500,000 tank carloads of petroleum crude oil, up from 9500 in 2008 (a 5300% increase). In light of continual growth in crude oil by rail, there is an urgent national need to manage this emerging risk. This need has been underscored in the wake of several recent crude oil release incidents. In contrast to highway transport, which usually involves a tank trailer, a crude oil train can carry a large number of tank cars, having the potential for a large, multiple-tank-car release incident. Previous studies exclusively assumed that railroad tank car releases in the same train accident are mutually independent, thereby estimating the number of tank cars releasing given the total number of tank cars derailed based on a binomial model. This paper specifically accounts for dependent tank car releases within a train accident. We estimate the number of tank cars releasing given the number of tank cars derailed based on a generalized binomial model. The generalized binomial model provides a significantly better description for the empirical tank car accident data through our numerical case study. This research aims to provide a new methodology and new insights regarding the further development of risk management strategies for improving railroad crude oil transportation safety. PMID:26298272

    2004-01-01

    Permafrost along the Qinghai-Tibet Railroad produces the great change under the influence of climate change, such as the decreasing of permafrost table, the rising of permafrost temperatures, etc. Climate effect on permafrost is the long-term process. Engineering action makes rapidly permafrost the large extent change. On the basis of analyzing the permafrost change under the climate change and engineering action, the thermal regime and spatial distribution of permafrost are predicted for air temperature rising 1℃ and 2℃ after 50 years in this paper. The results show that climate change results in the larger change for the thermal regime and spatial distribution of permafrost. Permafrost change will produce the great effect on the Qinghai-Tibet Railroad engineering, not only resulting in the decreasing of permafrost table beneath the roadbed, but also resulting in thawing settlement due to the thawing of ground ice near permafrost table. The idea of cooling roadbed and active protecting permafrost for the Qinghai-Tibet Railroad engineering could adjust and control the permafrost thermal state, some better methods are provided to ensure the engineering stability in the areas of warm permafrost and high ice content.

    Non-diffracting Bessel beams, including zero-order and high-order Bessel Beams which carry orbital angular momentum (OAM), enable a variety of important applications in optical micromanipulation, sub-diffraction imaging, high speed photonics/quantum communication, etc. The commonly used ways to create Bessel beams, including an axicon or a digital hologram written to a spatial light modulator (SLM), have great challenges to operate at the nanoscale. Here we theoretically design and experimentally demonstrate one kind of planar Bessel beam generators based on metasurfaces with analytical structures perforated in ultra-thin metallic screens. Continuous phase modulation between 0 to 2π is realized with a single element. In addition, due to the dispersionless phase shift stemming from spin-orbit interaction, the proposed device can work in a wide wavelength range. The results may find applications in future optical communication, nanofabrication and super-resolution imaging, etc.

    2001-12-01

    The study deals with an area of 589,062 m2 occupied by a national railroad shop located in Aguascalientes, a city in the central part of Mexico. Since 1903, the city became a transcendental railway center in the country and a transportation route toward the United States. Main activities were maintenance and repair of railroads cars, supply of fuel, and foundry of metallic pieces. The place was contaminated for 100 years, up to the recent sale of that company. The workshop area, now surrounded by populated urban areas, is abandoned. This study presents an evaluation of a previous survey of soil contamination in the different areas of the workshop. Based on our evaluation, we are proposing an optimal handling and remediation of the area. The survey referred 19 shallow boreholes (0-12 meters). Cores and chemical samples were analyzed. We defined the most relevant characteristic and contaminants of the soil samples. In terms of health risk analysis, we conclude that the most important contaminants are hydrocarbons and heavy metals. The following areas present the most significant health risk: the fuel supply zone , the oil petroleum or tar (called in Mexico "chapopote") lagoon, the painting area and the dump of axes and wheels.

  19. INTERLINE 5.0 -- An expanded railroad routing model: Program description, methodology, and revised user's manual

    International Nuclear Information System (INIS)

    A rail routine model, INTERLINE, has been developed at the Oak Ridge National Laboratory to investigate potential routes for transporting radioactive materials. In Version 5.0, the INTERLINE routing algorithms have been enhanced to include the ability to predict alternative routes, barge routes, and population statistics for any route. The INTERLINE railroad network is essentially a computerized rail atlas describing the US railroad system. All rail lines, with the exception of industrial spurs, are included in the network. Inland waterways and deep water routes along with their interchange points with the US railroadsystem are also included. The network contains over 15,000 rail and barge segments (links) and over 13,000 stations, interchange points, ports, and other locations (nodes). The INTERLINE model has been converted to operate on an IBM-compatible personal computer. At least a 286 computer with a hard disk containing approximately 6 MB of free space is recommended. Enhanced program performance will be obtained by using arandom-access memory drive on a 386 or 486 computer

  20. Seismic interferometry of railroad induced ground motions: body and surface wave imaging

    Science.gov (United States)

    Quiros, Diego A.; Brown, Larry D.; Kim, Doyeon

    2016-04-01

    Seismic interferometry applied to 120 hr of railroad traffic recorded by an array of vertical component seismographs along a railway within the Rio Grande rift has recovered surface and body waves characteristic of the geology beneath the railway. Linear and hyperbolic arrivals are retrieved that agree with surface (Rayleigh), direct and reflected P waves observed by nearby conventional seismic surveys. Train-generated Rayleigh waves span a range of frequencies significantly higher than those recovered from typical ambient noise interferometry studies. Direct P-wave arrivals have apparent velocities appropriate for the shallow geology of the survey area. Significant reflected P-wave energy is also present at relatively large offsets. A common midpoint stack produces a reflection image consistent with nearby conventional reflection data. We suggest that for sources at the free surface (e.g. trains) increasing the aperture of the array to record wide angle reflections, in addition to longer recording intervals, might allow the recovery of deeper geological structure from railroad traffic. Frequency-wavenumber analyses of these recordings indicate that the train source is symmetrical (i.e. approaching and receding) and that deeper refracted energy is present although not evident in the time-offset domain. These results confirm that train-generated vibrations represent a practical source of high-resolution subsurface information, with particular relevance to geotechnical and environmental applications.

    2015-01-01

    Full Text Available The paper considered the issues the Kuban Region railroad transportation has faced during the Second Five-Year Plan. The author has brought to light the ways people had to cope with the challenges in rearranging the maintenance schedule at the Northern Caucasus Railroad Dept., and the staffing issue being pressing at that period. The survey has shown the part taken by the Communist Party and pubic administration bodies in implementing tasks the railroad transportation has faced. The paper examined resolutions taken in the 1930-ies by the Krasnodar city CPSU conferences and the Krasnodar city Party activists in relation to challenges the railroad transportation faced. The author made an inference that the new means and labour incentive approaches have taken the main part in increasing the rail traffic flow, and wide spreading of socialist emulation and the raising Stakhanovism on the railroad as well.

    Samsonkin Valerii M.

    2014-01-01

    Full Text Available Changes in the socio-economic environment of functioning of railroad companies and corresponding transition to market economic conditions make us deeply reconsider our relation to the human factor as the main source of increase of the level of efficiency of both individual railroad enterprises and companies in general. But, apart from exclusively humanistic (evolution relation to this process, it is necessary to find means of formalisation of professional activity of a person or certification of personnel. The article is devoted to the above stated issues. In the result of the study the article develops a model of analysis of professional activity of a person at railroad transport, which gives a possibility to numerically determine the level of intellectual, social and physical components of the human factor and also to identify directions and efficiency of investing and a model of determination of the number, which ensures optimisation of the number of personnel of enterprises and structural subdivisions. In order to identify the most significant resources that are connected with personnel, time, place, method, motivation type, obtained effect and intensity of railroad transport operation the article offers to analyse results of professional activity of personnel of each structural subdivision by the “what” is created / developed / performed (regarding professional activity, “where” (enterprise name and its subordination,“when” and “who” created (developed / performed and “how” and “why” scheme.

  1. Preliminary characterization of the F-Area Railroad Crosstie Pile at the Savannah River Site. Revision 1

    Energy Technology Data Exchange (ETDEWEB)

    1991-10-01

    Historical information about the F-Area Railroad Crosstie Pile is limited. The unit is believed to have been a borrow area for earth fill that began receiving railroad crossties during the 1960s. The number of crossties at the unit began to increase significantly in 1984 when major repair of the SRS rail system was initiated. An estimated 100,000 used railroad crossties have accumulated at the unit since 1984. In an effort to determine the impact of the railroad crossties on the environment a total of 28 soil samples were collected from four test borings in March of 1991. Sample depths ranged from ground surface to 21.5 feet. Three of the borings were extended to the water table and groundwater samples were collected, one in an upgradient ``background`` area, and two downgradient from the unit. Few analytes were reported above detection limits. Test results are summarized in Section 4.0 and analytes not detected are summarized in Appendix A to this report. In three soil samples collected from depths between 10 and 21.5 feet, copper occurred at levels slightly above background. These copper values were detected in the sidegradient test boring and in the two downgradient test borings. Three organic analytes, acetone, pyridine, and Toluene, were reported above detection limits but well below drinking water standards (DWS) in all test borings, including the upgradient boring. Radionuclide activities were reported above background in both soil and water samples from all test borings. There do not appear to be any statistically significant trends in radionuclide activities with depth, or between upgradient or downgradient borings. The analytes detected in the test borings downgradient from the unit cannot be attributed to the railroad crosstie pile as they are not significantly different than the values reported for the upgradient, background test boring.

  9. Connectivity structure of the Kosi megafan and role of rail-road transport network

    Science.gov (United States)

    2014-12-01

    Movement of biophysical fluxes and resultant processes are governed by among other things, the (dis)connectivity structure of a landform. Hence, the quantification of connectivity structure of a landform is important in order to analyze water and sediment fluxes over a surface. Two dimensional connectivity structure through analysis of lateral and longitudinal connectivity for water and sediment flux has been quantitatively defined for the well-known Kosi megafan in north India. The avulsive behavior of the Kosi River has resulted in various paleochannels over the megafan, and they guide the flux transfer over the surface and also control the local topography of the megafan. As (dis)connectivity structure of landform is governed by its physical characteristics and also affected by anthropogenic disturbances, both these factors have been considered to quantitatively analyze the connectivity structure of the Kosi megafan for sediment and water fluxes. Megafan surface characteristics have been defined through local slope variability, land use-land cover map and flow length. These surface parameters have been used to map ‘buffers' in the area. The distribution pattern of ‘buffers' on the megafan surface has been used to define the ‘natural' (dis)connectivity structure. Further, the megafan surface has also been affected by progressive development of the rail-road transport network, which is mostly east-west aligned and intersects the south flowing paleochannels. These rail-road network acts as an anthropogenic ‘barrier' for water and sediment fluxes across the megafan surface. A detailed mapping of rail and road network in different years (1955, 1983 and 2010) has been used to characterize anthropogenic disturbance on the connectivity structure. The spatio-temporal variation in connectivity structure is attributed to density of the transport network. Finally, natural and anthropogenic disturbances on connectivity structure have also been integrated to

Proposals on automate calculations in distances and services by way of determining the permissible speeds in curves were developed. Originality. Methodology of determining the permissible motion speeds and elevation of outer rails on the difficult sections of the railway plan was developed. This approach allows you to get a rational decisions on reorganization of plan based on local conditions. Practical value. The developed technique of definition of admissible speeds of motion in curves was implemented as a program DopShvid. The program was tested on real railway sections, where the accelerated train motion was introduced.

  11. Evaluation of a force plate system for measuring center of pressure in railroad ballast.

    2016-05-01

    Traditional biomechanical analyses have focused primarily on the human gait across hard, flat surfaces and provide little information about human locomotion as a function of work environment or terrain. The purpose of this study was evaluation of a force plate system for measure of center of pressure (COP) in railroad ballast by comparing its accuracy across three surface conditions (hard surface, mainline ballast and walking ballast) with two configurations (level and 7° cross-slope). Custom walkways and an isolation fixture were developed to rigidly attach a force plate beneath ballast surfaces to collect the COP. The difference in COP location (ΔCOPx, y, z) between the force plate system and a calibration system (motion capture derived) were compared using repeated-measures analysis of variance. Results indicate that the effects of surface condition and configuration were not significant for ΔCOPx, y, z and no differences were found among the three surface conditions during pairwise comparison, though ΔCOPx, y, z were different between the center and corners of the force plate in ballasts for both level and cross-slope configurations. The system presented in this study demonstrates the feasibility of measuring the COP by using an isolation-fixture force plate to expand the scope of biomechanical studies on ballast surfaces that are level or cross-slope.

  12. Vibration energy harvesting system for railroad safety based on running vehicles

    International Nuclear Information System (INIS)

    This research is focused on energy harvesting from track vibration in order to provide power for the wireless sensors which monitor railroad health. Considering that track vibration has vibration energy, a new method is proposed in the paper to harvest energy based on the piezoelectric effect. The piezoelectric generator called drum transducer is the key part for track vibration energy harvesting. The model of drum transducer is established and the simulation results show that it can generate 100 mW in real track situation. In addition, an experiment rig is developed and its vibration model is also established. The simulation and experiment results show that peak open-circuit voltage of piezoelectric generator is about 50–70 V at the full load of the train. The whole track vibration energy harvesting system is analytically modeled, numerically simulated, and experimentally realized to demonstrate the feasibility and the reliability of the theoretical model. This paper is the theoretical basis of harvesting, recovering and recycling of the track vibration energy for track safety. (paper)

    Full Text Available

    The paper reports the latest results of a study conducted on a hybrid train in which a gas turbine, operating in several alternative control modes (fixed point, on-off or load-following, generates the electrical energy for recharging a battery package and for driving the electric motors of a suburban train. The model, originally developed for automotive applications, has been validated by experimental tests performed on an ELLIOTT TA-45 GT group in the ENEA-Casaccia Research Center.

    This paper describes the preliminary design of the traction system and the choice of the energy flow control strategy. Numerical simulations have been carried out, based on an actual train mission (the Norwegian railroad track between Asker and Lillehammer and on industrial data for the single components. Following two different approaches, separate optimizations of the gas turbine set and battery package are performed, in which the objective function is the monetary cost per mission or, which is equivalent, the kWh/(t·km for a given mission profile.

  14. Automated radiological scanning of potentially contaminated railroad crossties for free-release or disposal

    International Nuclear Information System (INIS)

    The Savannah River Site (SRS) has accumulated approximately 300,000 crossties that have been replaced over a 40-year period of maintaining the site's 62 miles of railroad track. The ties reside in a pile on an open area of 2.3 acres near the site's F-Area facilities. A small fraction of the ties are potentially contaminated with radioactivity as a result of past site practices and service. Contamination was possible from occasional leaks in transport-casks moved by rail from the site's five nuclear materials production reactors to its two reprocessing facilities. Casks typically were filled with spent fuel, targets, and water from the reactor disassembly basins, which contained small amounts of fission and neutron activation product radioactivity normal to the operation of nuclear reactors. What to do with the ties has been debated for sometime. Proposals have ranged from simple burial, to bio-remediation, to burning as a fuel in the site's powerhouse, to free-release to off-site markets. In the past, burial was the disposal method of choice; however, the Department of Energy (DOE) order 5820.2A and premium on new space for low-level waste largely rule out burial. Instead, the last option is now cost effective and was begun under a contract with National Environmental Services Corporation started in January, 1996

  15. Assessment of the potential for biodegradation of petroleum hydrocarbons in the Railroad Industrial Area, Fairbanks, Alaska

    Many technologies for the clean-up of petroleum-hydrocarbon contaminated sites depend on microbial degradation of the pollutant. In these technologies the site may be modified to enhance microbial activity, or may simply be monitored for naturally occurring microbial activity. In either case, an important aspect of site assessment for these technologies is to determine if the microorganisms present at the site have the potential to break down contaminants under the prevailing environmental conditions. We examined the numbers and activity of hydrocarbon-degrading microorganisms in ground water collected from petroleum-hydrocarbon contaminated and uncontaminated wells at the Railroad Industrial Area near Fairbanks, Alaska. We found that the population of gasoline-degrading microorganisms in ground water was correlated to the degree of contamination by benzene, toluene, ethylbenzene and xylenes (BTEX). We also found that these organisms could actively mineralize these types of compounds in laboratory mineralization assays. Increasing temperature and adding nutrients both enhanced the rate of mineralization in the laboratory, but measurable degradation still occurred under conditions similar to those found in the field. Dissolved oxygen in ground water at this site ranged from 0 to 3.6 milligrams per liter. Therefore, oxygen may not always be available to microorganisms as a terminal electron acceptor. Preliminary geochemical evidence from the field indicates that alternative electron acceptors such as Fe(III), sulfate, or nitrate may be used, contributing to degradation of contaminants at this site.

    Full Text Available The purposes of this research have been to determine the wastewater quality of a typical railroad repair workshop and to find a way to reduce the concentrations of present contaminants especially oil and grease. The mean concentrations of oil, COD and SS in the wastewater studied were 287.69, 775.85 and 28723, respectively with average daily discharge to be 30-35 m3. Three successive treatment processes were used and the results showed the first stage was gravity flotation with 90 minutes retention time. Removal efficiencies achieved for COD, SS and oil were determined 43%, 49.4% and 55.5% respectively. The second stage of treatment was coagulation either lime or ferric chloride could be used for this purpose at PHs of 9 and 6. COD and oil removals by lime treatment were 76.6% and 84.4%. The final stage of treatment was DAF at 3 atmospheric pressure, by which 92.5%, 89.5%, 89.92% and 88% removals were achieved for oil, SS and COD, respectively.

  19. Ion and particle number concentrations and size distributions along the Trans-Siberian railroad

    International Nuclear Information System (INIS)

    Aerosol concentrations and properties in Russia are not well known. There are only few studies published on aerosols in Russia. However, these aerosols can have a major effect on global climate. We measured aerosol particle and air ion number size distributions together with relevant information on meteorological conditions and atmospheric trace gas concentrations in Russia. Our purpose was to get new insight on number concentrations of aerosol particle and air ions in different parts of Russia, and to examine which sources and sinks affected the observed concentrations. During a two-week TROICA-9 expedition between 4 and 18 October 2005, we travelled on the Trans-Siberian railroad from Moscow to Vladivostok and back, conducting measurements constantly along the route. The lowest aerosol particle number concentrations, around 500 cm-3, were observed at remote sites and the highest concentrations of around 40000 cm-3 were observed near large industrial towns. The particle number concentration correlated best with nitrogen oxide and carbon monoxide concentrations. Pollutant levels were at their highest in the vicinity of towns, even though important pollution sources such as wood burning and forest fires also existed in rural areas. Concentrations of positive and negative intermediate and large ions were of the same order of magnitude as has been observed in previous studies made in boreal forests. Concentrations of intermediate ions were often low of the order of a few ions cm-3, but their concentration increased during nucleation, rain and snowfall events. Concentrations of positive and negative cluster ions were sometimes very high, reaching values of about 5000 cm-3 in case of negative ions. We also detected exceptionally high ion production rates of up to 30 s-1 cm-3 due to 222-radon decay. Concentrations of cluster ions correlated quite well with the ion production rate but less so with the ion sink. Two particle formation events were observed, during which the

    International Nuclear Information System (INIS)

    comments and the environmental analyses in the Repository EIS, DOE identified a preference for the Caliente rail corridor in Nevada. This corridor is approximately 513 kilometers (319 miles) long and would cost an estimated $880 million (2001 dollars). Should DOE decide to build the Caliente corridor, it may be the longest rail line built in the United States since the Transcontinental Railroad was constructed in 1869. Some of the challenges in building this rail corridor are steep grades (the corridor crosses over 7 mountain ranges), isolated terrain, possible tunnels, and stakeholder acceptance

    The aim of this study is to investigate and compare vibration and shock measurements of maintenance-of-way vehicles used in the railroad industry for track maintenance and construction. Following international standards (i.e., ISO 2631-1: 1997) and professional guidelines the frequency weighted root-mean-square (r.m.s.) acceleration for each measurement axis, the vector sum, the seat effective amplitude transmissibility (SEAT), the crest factor (CF), the maximum transient vibration value (MTVV), the vibration dose value (VDV), the ratio and the newly proposed shock risk estimation factor 'R' for spinal injury according to ISO 2631-5:2004 were measured and calculated for seven different maintenance-of-way vehicles during revenue service. Furthermore, a proposed alternative spinal injury prediction method, the VibRisk model, which incorporates different typical driver postures and operator physical characteristics was included for comparison with the ISO 2631-5 risk prediction. The results of the vibration exposure measurements depended on vehicle type, track/surface conditions and seat properties, with the tamper and bulldozer showing the highest r.m.s. vibration values. The vector sum (a(v)) results ranged from 0.37 to 0.99 (m/s(2)). Five of seven track maintenance vehicles would exceed the current Whole-body Vibration ACGIH-TLV(®) guideline for an 8 h exposure duration in the vertical axis recommended by the American Conference of Governmental Industrial Hygienists (ACGIH). The measured CF, MTVV/a(w) and VDV/(a(w)·T(1/4)) ratios were at or above the critical ratios in the majority of measurements given by the ISO 2631-1 (1997) and American industry guidelines by the American Conference of Governmental Industrial Hygienists (ACGIH-TLV). Comparing both prediction models for vibration shock risk for parts of the lumbar spine, different risk predictions and inconsistencies were found. The VibRisk model generally suggests different and higher risk of vertebral

  3. Health assessment for Western Pacific Railroad, Oroville Yard, Oroville, Butte County, California, Region 9. CERCLIS No. CAD980894679. Preliminary report

    International Nuclear Information System (INIS)

    The Western Pacific Railroad's (WPR) Oroville yard, near Oroville, California, has been proposed for inclusion on the U.S. Environmental Protection Agency's National Priorities List (NPL). WPR operated the 90-acre railyard for almost 60 years until the railyard was purchased by Union Pacific Railroad (UPR) in 1983. The servicing and repair of railcars on the site generated petroleum product wastes, chlorinated solvent waste, and heavy metal wastes that have migrated into the soils of the area. The WPR site is located on dredger tailings east of the Feather River, two miles south of Oroville. The Regional Water Quality Control Board (RWQCB) has identified three primary sources of contamination on site: a roundhouse or fueling area, an unlined surface impoundment, and an API oil-water separator. Other industries, also built over the dredger tailings, are in the vicinity of the site. The limited data available on concentrations of contaminants on site and off site are not sufficient to determine if humans are being or have been exposed to levels of contamination that would be expected to cause adverse health effects. Although there is no evidence at this time that WPR is the source, the burning of petroleum and chlorinated solvent wastes, such as took place at the pond on this site, has been known to generate dioxins and furans. Therefore, this site is classified as an indeterminate public health hazard

    Methods of assessing occupational exposure to diesel exhaust were evaluated in a railroad work environment. The American Conference of Governmental Industrial Hygienists (ACGIH)-recommended elemental carbon and respirable combustible dust methods of sampling and analysis for assessing diesel exhaust were included in the study. A total of 215 personal and area samples were collected using both size-selective (nylon cyclone and Marple) and non-size-selective samplers. The results demonstrate that the elemental carbon method is suitable for the railroad environment and the respirable combustible dust method is not. All elemental carbon concentrations measured were below the proposed ACGIH Threshold Limit Value (TLV) of 0.15 mg/m3. The concentrations of oxides of nitrogen (nitric oxide and nitrogen dioxide) were also found to be below their respective TLVs. There is no correlation between elemental carbon or respirable combustible dust and the oxides of nitrogen. The elemental carbon as fraction of total carbon is about 13 percent, except for onboard locomotives where it is about 24 percent. Comparison of elemental carbon and respirable combustible dust measurements showed consistent relationships for most sampling locations, with respirable combustible dust concentrations 12 to 53 times higher than the elemental carbon levels.

    The results of a study of the structure and mechanical properties of a steel strip cut from the first railroad bridge across the Ob river constructed 120 years ago are given. The steel for the bridge was made at the Votkinsk plant in the Urals at the end of the 19th century. In this work, the chemical composition of the steel has been analyzed and a comparison of the quality of the material with the contemporary analogs has been carried out. It has been established that the steel used in the production of the bridge is characterized by a low content of sulfur and phosphorus. At the same time, the metal contains an enhanced content of nonmetallic inclusions. The presence of inclusions oriented in the rolling direction favorably affects the resistance to fatigue cracking of the steel. The cracks are retarded at the boundaries between the inclusions and the metallic matrix.

  10. On site treatment of NORM for surface waste disposal in Texas under Texas Railroad Commission Rule 94

    International Nuclear Information System (INIS)

    Remediation of Naturally Occurring Radioactive Material (NORM) by surface disposal under the provisions of Texas Railroad Commission Rule 94 and the applicable provisions of the Texas Department of Health Radiation Control Regulations is permitted under current State regulation and represents a viable alternative to commercial disposal under many circumstances. The economic advantages of on-sit disposal compared with commercial disposal can be significant, provided the generator is aware of the limitations of on-site disposal and has enough information and expertise to ensure a successful project. This report examines the experience gained from disposals performed under Rule 94 and summarizes the methods used and the results of actual NORM disposal projects at production sites under varying field conditions

    2007-09-01

    Full Text Available Background: Introduction of health impact assessment (HIA as a national legal requirement for planned economic activity projects in 2002 and the further development of related procedures and methodological requirements has boosted the number of HIAs carried out both as an integrated part of environmental impact assessment (EIA procedures as well as an independent activity. Most of HIAs have been conduct for local projects. The HIA for the reconstruction of the southern section of the railroads in Klaip da National Seaport is one of the local HIAs in Lithuania carried out as an independent procedure. Methods: The HIA for the reconstruction of the southern section of the railroads in Klaipda National Seaport was carried out following the national legal procedure for the cases not foreseen in the Law on Environmental Impact Assessment of Planned Economic Activity and the national HIA methodological regulations. The HIA included a literature review, analysis of related technical documentation, data on existing and estimated air pollution and environmental noise levels and possible health consequences, analysis of local demographic and health statistics; interviews with the residents living in proximity of the planned activity, analysis of public complaints on existing activities at Klaip da National Seaport, site visit and round table discussions with the proponent of the planned activity, planning company and representatives of the public health authority. The standard or intermediate type of perspective HIA was applied. Results: The HIA report has pointed out noise, vibration, ambient air pollution, psychological factors as related to possible negative impact on health of residents living in the mostly exposed locations. Interviews with inhabitants living in proximity of the planned activity have shown that majority of them knew nothing about the reconstruction plans. Recommendations were provided in the report how to minimise

  13. The radial hardness-profile and the microstructure of railroad car axle materials treated by surface rolling, determined by novel examination methods

    International Nuclear Information System (INIS)

    Surface rolling is a cold-working technique used for hardening the surface of steel and ductile cast iron components. This process increases the surface hardness and improves the fatigue properties of components, so it is commonly used to treat railroad car wheel axles. The present paper examines the influence of this surface strengthening technique on the microstructure of the railroad car wheel axle material by hardness tests, optical microscopy (OM), and other novel examination methods, such as scanning electron microscopy (SEM), X-ray line profile analysis (XLPA), non-destructive magnetic evaluation (NDE) and automated electron backscatter diffraction (EBSD). The results show that surface rolling causes an increase in hardness down to a depth of ∼10 mm. It is also shown, that the increase in hardness is not due to grain refinement or change in grain morphology; thus it is likely to be caused by an increase in dislocation density

  15. Boarding and alighting injury experience with different station platform and car entranceway designs on US commuter railroads.

    Commuter railroad systems in the US employ three combinations of station platforms and car entranceways. These are high-level platforms with remotely controlled doors and level entranceway (HL-RC), low-level platforms (just above the rail) with steps and remotely controlled doors (LL-RC), and a mixture of the two platform types with a correspondingly more complex, partly manual, door and entranceway arrangement (ML-MO). Much controversy exists over which type of platform/entranceway is better. This seemingly small feature significantly impacts many performance characteristics of these systems, including cost, speed, and boarding and alighting accidents. Northeastern systems are generally moving toward the mixed platform design or all high-level platforms, while systems elsewhere are generally selecting the low-level design. Data on actual accident experience for 1995-2000 are analyzed to determine the effect of platform/entranceway type on passenger and employee injuries. Passenger injury rates on systems with the HL-RC design are lowest, with LL-RC systems next, and ML-MO systems having the highest rates. Employee injury rates are the least on LL-RC systems, but higher on ML-MO and HL-RC systems. Systems with a mixture of high and low platforms (ML-MO) experience a higher overall (combined passenger and employee) injury rate than the other two designs. The implications of these results for both the modernization of existing systems and the design of new systems, in the US and abroad, are discussed. PMID:14642881

    AIM: To investigate the gastrointestinal bleeding (GIB) in people from lowland to high altitude and in workers on Mountain Tanggula and its causes as well as treatment and prophylaxis.METHODS: From 2001 to October 2003, we studied GIB in 13 502 workers constructing the railroad on Mountain Tanggula which is 4905 m above the sea level. The incidence of GIB in workers at different altitudes was recorded. Endoscopy was performed when the workersevacuated to Golmud (2808 m) and Xining (2261 m).The available data on altitude GIB were analyzed.RESULTS: The overall incidence of GIB was 0.49% in 13502 workers. The incidence increased with increasing altitude. The onset of symptoms in most patients was within three weeks after arrival at high altitude. Bleeding manifested as hematemesis, melaena or hematochezia,and might be occult. Endoscopic examination showed that the causes of altitude GIB included hemorrhage gastritis, gastric ulcer, duodenal ulcer, and gastric erosion. Experimental studies suggested that acute gastric mucosal lesion (AGML) could be induced by hypoxic and cold stress, which might be the pathogenesis of altitude GIB. Those who consumed large amount of alcohol, aspirin or dexamethasone were at a higher risk of developing GIB. Persons who previously suffered from peptic ulcer or high-altitude polycythemia were also at risk of developing GIB. Early diagnosis, evacuation, and treatment led to early recovery.CONCLUSION: GIB is a potentially life threatening disease, if it is not treated promptly and effectively. Early diagnosis, treatment and evacuation lead to an early recovery. Death due to altitude GIB can be avoided if early symptoms and signs are recognized.

  17. Streamlined Approach for Environmental Restoration (SAFER) Plan for Corrective Action Unit 539: Area 25 and Area 26 Railroad Tracks, Nevada Test Site, Nevada, Revision 0

    This Streamlined Approach for Environmental Restoration (SAFER) Plan addresses the actions needed to achieve closure for Corrective Action Unit (CAU) 539, Areas 25 and 26 Railroad Tracks, as identified in the Federal Facility Agreement and Consent Order (FFACO). A modification to the FFACOwas approved in May 2010 to transfer the two Railroad Tracks corrective action sites (CASs) from CAU 114 into CAU539. The two CASs are located in Areas 25 and 26 of the Nevada Test Site: • 25-99-21, Area 25 Railroad Tracks • 26-99-05, Area 26 Railroad Tracks This plan provides the methodology for field activities needed to gather the necessary information for closing the two CASs. There is sufficient information and process knowledge from historical documentation and investigations of similar sites regarding the expected nature and extent of potential contaminants to recommend closure of the CAU 539 Railroad Tracks CASs using the SAFER process. Additional information will be obtained by conducting a field investigation before selecting the appropriate corrective action for each CAS. The results of the field investigation should support a defensible recommendation that no further corrective action is necessary. If it is determined that complete clean closure cannot be accomplished during the SAFER, then a hold point will have been reached and the Nevada Division of Environmental Protection (NDEP) will be consulted to determine whether the remaining contamination will be closed under the alternative corrective action of closure in place with use restrictions. This will be presented in a closure report that will be prepared and submitted to the NDEP for review and approval. The sites will be investigated based on the data quality objectives (DQOs) developed on December 14, 2009, by representatives of U.S.Department of Energy (DOE), National Nuclear Security Administration Nevada Site Office; Navarro Nevada Environmental Services, LLC (NNES); and National Security Technologies

    Several studies have shown that human transportation networks exhibit small-world structure, meaning they have high local clustering and are easily traversed. However, some have concluded this without statistical evaluations, and others have compared observed structure to globally random rather than planar models. Here, we use Monte Carlo randomizations to test US transportation infrastructure data for small-worldness. Coarse-grained network models were generated from GIS data wherein nodes represent the 3105 contiguous US counties and weighted edges represent the number of highway or railroad links between counties; thus, we focus on linkage topologies and not geodesic distances. We compared railroad and highway transportation networks with a simple planar network based on county edge-sharing, and with networks that were globally randomized and those that were randomized while preserving their planarity. We conclude that terrestrial transportation networks have small-world architecture, as it is classically defined relative to global randomizations. However, this topological structure is sufficiently explained by the planarity of the graphs, and in fact the topological patterns established by the transportation links actually serve to reduce the amount of small-world structure.

  1. 应用冷却路基原理建设青藏铁路%Constructing of the Qinghai-Tibet Railroad Using the Principle of Cooling the Roadbed

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    More than half of the total length of the Qinghai-Tibet Railroad (QTR) traverses warm (0 to-1 ℃) permafrost areas, and about 40% of its total length is in ice-rich permafrost areas. The construction of the QTR also must consider the impacts of climatic warming along the QTR during the next 50~100 years. The latest projection indicates a warming of 2.2 to 2.6 ℃ on the Qinghai-Tibet Plateau (QTP) by the year 2050. Therefore, the key to the successful construction of the QTR is to protect permafrost from being thawed. Although railroad construction in permafrost areas has had a history of more than 100 years, the troubled sections of the railroads in permafrost areas have been greater than 30% of their total length. Based on the experiences and lessons learned from the road construction in permafrost areas, both in China and abroad, the author proposes that the principle of"active cooling"of railroad roadbed by lowering permafrost temperatures should be used in designing QTR, rather than that of"passive protection" of permafrost through increasing thermal resistance of roadway, such as increasing fill thickness and/or using insulative materials. This is especially important for the road sections in warm, ice-rich permafrost. In addition, this paper proposes several methods for"cooling the roadbed" by controlling radiation, convection and conduction through modifying roadway structure and using different fill materials.

    A radiological survey was conducted at the Pennsylvania Railroad Landfill Site in Burrell Township, Pennsylvania. In 1956 and 1957, approximately 11,600 tons of radioactive material was dumped at this site and was apparently scattered over an area of loss than 10 acres. The survey included measurement of the following: external gamma radiation at 1 m above the surface and at the surface throughout the site; beta--gamma dose rates at 1 cm from the surface throughout the site; concentrations of 226Ra and 238U in surface and subsurface soil on the site; concentrations of 210Pb, 226Ra, 230Th, and 238U in subsurface water on the site and in surface water on and near the site; and the extent of atmospheric transport of 222Rn and progeny from the site. The general location of the residues transported to the site, except possibly small, scattered quantities of materials, was determined from the survey. In some areas on the site, beta--gamma dose rates of 1 cm from the surface were above pertinent guidelines.Analyses of sediment from water samples taken from drainage areas near the site indicate that some radioactive material is being carried from the site by surface run-off. Results of this survey indicate that there is no significant atmospheric transport of 222Rn from the site

    The total columns of carbon dioxide (XCO2) and methane (XCH4) were measured with a compact Fourier transform spectrometer (FTS) at NASA Armstrong Flight Research Center (AFRC) and Railroad Valley, Nevada, USA (RRV) during a vicarious calibration campaign in June 2014. The campaign was performed to estimate changes in the radiometric response of the Thermal and Near Infrared Sensor for carbon Observations Fourier Transform Spectrometer (TANSO-FTS) and the Cloud and Aerosol Imager (TANSO-CAI) aboard Greenhouse gases Observing SATellite (GOSAT). TANSO-FTS measures spectra of radiance scattered by the Earth surface with high- and medium-gain depending on the surface reflectance. At high reflectance areas, such as deserts over north Africa and Australia, TANSO-FTS collects spectra with medium-gain. There was differences on atmospheric pressure and XCO2 retrieved from spectra obtained between high-gain and medium-gain. Because the retrieved products are useful for evaluating the difference of spectral qualities between high- and medium-gain, this work is an attempt to collect validation data for spectra with medium-gain of TANSO-FTS at remote and desert area with a compact and medium-spectral resolution instrument. As a compact FTS, EM27/SUN was used. It was manufactured and newly released on April 1, 2014 by Bruker. It is robust and operable in a high temperature environment. It was housed in a steel box to protect from dust and rain and powered by Solar panels. It can be operated by such a remote and desert area, like a RRV. Over AFRC and RRV, vertical profiles of CO2 and CH4 were measured using the Alpha Jet research aircraft as part of the Alpha Jet Atmospheric eXperiment (AJAX) of ARC, NASA. The values were calibrated to standard gases. To make the results comparable to WMO (World Meteorological Organization) standards, the retrieved XCO2 and XCH4 values are divided by a calibration factor. This values were determined by comparisons with in situ profiles measured by

    Background It is important to determine the incidence of acute mountain sickness (AMS) among workers at altitudes between 3500 m and 5000 m on Mt.Tanggula during the construction of the Qinghai-Tibet railroad.This study explored the risk factors predisposing workers to developing AMS and attempted to develop more effective ways of preventing and treating AMS.Methods A total of 11 182 workers were surveyed by completing twice daily a Lake Louise questionnaire,and a score ≥3 indicated AMS.The contributing risk factors were assessed for at least 2 months for the duration of the study in the years from 2001 to 2003.A risk model was developed by multiple Logistic regression.Standard statistical methods were used to analyze data.Results AMS occurred in 56% of workers working at high altitudes on Mt.Tanggula.The incidence of AMS increased with increasing altitude.Rapid ascent to an altitude above 3500 m,sea-level or lowland newcomers,young people under 25 years of age,heavy physical exertion,obese person,and arterial oxygen saturation (SaO2) below 80% were independent AMS risk factors.No significant association was found between AMS and sex or taking Rhodiola.Medical education contributed to an early diagnosis of AMS.Conclusions This study used the Lake Louise scoring system suggesting that it is a well-validated standard for field evaluation of AMS and for making an early diagnosis.These studies have described many variables regarding risk factors for the development of AMS.Risk factors which can be modified should be attended to,and the physicians should carry out check-ups and tests to identify subjects who are more at risk.Prevention consists in continuous gradual ascent,medical education,and prompt descent to avoid progression in patients with serious AMS.It is most important to effectively control the risk factors of AMS.

  10. COMPOSITE SOLUTIONS IN RAILROAD ENGINEERING

    Directory of Open Access Journals (Sweden)

    Panfilova Marina Ivanovna

    2012-10-01

    Full Text Available Present-day methods of recovery of used wooden railway ties, including burial, chemical neutralization, gasification and subsequent burning, utilization in the capacity of composite materials, are expensive and unsafe for the environment. The authors propose a new method of their utilization. Ash generated in the course of their burning may replace a portion of cement in composite solutions and act as an additive to grouting mortars designated for the filling of the annulus space of manifold tunnels. The chemical composition of the ash was identified by the x-ray method applied to three samples taken during various periods of time from out of a dry-type dust collector. The level of human health/environmental hazard of the ash is based on its chemical composition. Changes in the rheological properties of composite solutions that contained concrete fractions, various ratios of ash, and 5% of liquid glass were studied in the course of the research. The experiments have proven that in the event of replacement of 20% of cement by ash, the strength of the composite solution is approximately the same as the one of the benchmark sample; therefore, this ash content ratio is deemed acceptable. The finding demonstrate that the ash has no toxic effect, and the ecological safety of this solution is thus confirmed. The authors have proven that 20% of cement may be replaced by the ash generated in the course of burning of waste railway ties.

    An automatic interpretation algorithm adapted for GPR images from railroad subgrade inspection is designed for massive data analysis, in order to tackle the problem of inadequate functions of the GPR supporting software. First the primary GPR data is processed, including radon transform for eliminating interferences caused by railway sleepers and KL transform in wavelet domain for removing random noise. Then part of radar wavelet is filtered by wavelet transform to display the interfaces and defect positions in railroad subgrade. Next an interface-test algorithm is proposed and the graph of interfaces for judging subgrade subsidence is plotted through tracing the interface position. Finally an expert system is established. All kinds of mud pumping in different localities are stored in defect library and studied by learning a vector quantization network model to obtain the classification rules for judgment of the types of mud pumping. The GPR data for the Shanghai-Nanjing railroad subgrade is processed by using the automatic interpretation algorithm, and the results indicate that it can automatically distinguish the types and positions of the defects, with a up to 90% recognition rate.%针对目前探地雷达随机配套软件功能的不足,为满足铁路路基雷达探测海量数据分析的需要,设计出适合于铁路路基检测图像的自动解释算法.首先对原始资料进行数据处理,采用拉冬变换消除轨枕影响,小波域KL变换消除随机噪声;再根据小波变换设计出反滤波算子滤除部分雷达子波,以突出层面和病害位置;提出层面检测算法,跟踪层面位置实现层面图的绘制,根据层面图判断路基是否下沉;建立专家系统,将不同地区的翻浆冒泥病害类型存入病害库,通过学习向量量化网络模型对其进行学习,得出判决规则,实现翻浆冒泥病害的识别.对铁路沪宁线检测资料进行模拟计算,结果表明:该算法能够自动区分铁路路基中

    2007-01-01

    A cross-calibration methodology has been developed using coincident image pairs from the Terra Moderate Resolution Imaging Spectroradiometer (MODIS), the Landsat 7 (L7) Enhanced Thematic Mapper Plus (ETM+) and the Earth Observing EO-1 Advanced Land Imager (ALI) to verify the absolute radiometric calibration accuracy of these sensors with respect to each other. To quantify the effects due to different spectral responses, the Relative Spectral Responses (RSR) of these sensors were studied and compared by developing a set of "figures-of-merit." Seven cloud-free scenes collected over the Railroad Valley Playa, Nevada (RVPN), test site were used to conduct the cross-calibration study. This cross-calibration approach was based on image statistics from near-simultaneous observations made by different satellite sensors. Homogeneous regions of interest (ROI) were selected in the image pairs, and the mean target statistics were converted to absolute units of at-sensor reflectance. Using these reflectances, a set of cross-calibration equations were developed giving a relative gain and bias between the sensor pair.

  15. The railroad perspective: Issues behind the issues

    International Nuclear Information System (INIS)

    Rail transportation is a vital segment of DOE's spent fuel program. Most of the shipments from reactors to a repository or to a Monitored Retrievable Storage facility will be by rail, and essentially all of the shipments from an MRS to a repository. Casks must move economically and efficiently, while at the same time providing adequate safety to the public and transport workers, and meeting the legal/institutional constraints. Shippers are faced with the problem of procuring transportation services in a safe manner at a reasonable cost, trying to balance freight charges against cask inventory costs. Carriers are cautious about accepting potentially high hazard materials in routine service, and are worried about uninsured losses in case of accidents. Both shippers and carriers operate under different scheduling and operational criteria. Technical and institutional constraints add to the complexity of the operation. Standardization of shipping casks and rail car design will ease the resolution of the complex problems now existent. This paper discusses the economic, safety, operational, and legal issues surrounding rail transportation

    The initial GC/MS calibration and continuing calibration met all protocols. The calibration working standard is made from 9 separate mixes. One of the mixes (Restek semivolatile mix 3) was doubled, increasing the calibration concentration curve by a factor of two. None of the compounds of interest were affected, and all of the forms have been adjusted. All mass spectral tuning requirements were met for all standards and samples. Internal standard criteria were met for field blank R5306. Perylene-d12 was out on the low side. This sample was reanalyzed and all internal standard criteria were met. The R5302rerr was reported instead of R5302re (the original run of the re-extract) because R5302re failed its internal standard criteria. RSBLK03rr was reported instead of RSBLK03 (the original run of the method blank) because RSBLK03 failed its internal standard criteria. Internal standard criteria for all other samples in this package were met.

    2012-06-01

    A series of microcatenas on the slopes of sinkholes were studied on the western macroslope of the southern Urals in the Shulgan-Tash Reserve. The morphological, chemical, physical, and physicochemical characteristics of the soils were analyzed. In order to reveal their regional specificity, the soils of the sinkholes under broadleaved forests in the southern Urals were compared with analogous soils under the northern taiga of the Belomorsk-Kuloi Plateau. It was shown that the full-profile vertically differentiated soils in the upper parts of the microcatenas are replaced by weakly developed and slightly differentiated soils in the lower parts of the microcatenas crossing sinkholes of different diameters in both natural zones.

    Full Text Available Não obstante o peso decisivo das receitas geradas pelo café para os balanços financeiros das ferrovias paulistas entre 1888 e 1917, e a centralidade da atividade cafeeira na economia paulista de então, discute-se neste artigo a especialização relativa ao nível da produção verificada em São Paulo e a questão dos fretes das ferrovias neste cenário. Parte-se da ideia de que a cafeicultura, em seu desenvolvimento, demandava a diversificação de culturas agrícolas, pois as unidades básicas de produção - as fazendas de café - não se caracterizavam unicamente pela monocultura, sendo que os nexos entre uma produção voltada à exportação e outra voltada ao mercado interno davam-se nas relações de trabalho estabelecidas entre contratantes e contratados, e nas formas pelas quais os fazendeiros expropriavam aqueles que se subordinavam aos seus interesses. Verifica-se no caso estudado o aumento simultâneo das quantidades de café e de alimentos transportadas e transacionadas pela Cia. Mogiana nos marcos da periodização proposta; porém, percebe-se estreita dependência em relação à receita gerada pelo transporte de café.

  6. Soil water storage and groundwater behaviour in a catenary sequence beneath forest in central Amazonia: I. Comparisons between plateau, slope and valley floor

    Directory of Open Access Journals (Sweden)

    M. G. Hodnett

    1997-01-01

    Full Text Available Soil water storage was monitored in three landscape elements in the forest (plateau, slope and valley floor over a 3 year period to identify differences in sub-surface hydrological response. Under the plateau and slope, the changes of storage were very similar and there was no indication of surface runoff on the slope. The mean maximum seasonal storage change was 156 mm in the 2 m profile but it was clear that, in the dry season, the forest was able to take up water from below 3.6 m. Soil water availability was low. Soil water storage changes in the valley were dominated by the behaviour of a shallow water table which, in normal years, varied between 0.1 m below the surface at the end of the wet season and 0.8 m at the end of the dry season. Soil water storage changes were small because root uptake was largely replenished by groundwater flow towards the stream. The groundwater behaviour is controlled mainly by the deep drainage from beneath the plateau and slope areas. The groundwater gradient beneath the slope indicated that recharge beneath the plateau and slope commences only after the soil water deficits from the previous dry season have been replenished. Following a wet season with little recharge, the water table fell, ceasing to influence the valley soil water storage, and the stream dried up. The plateau and slope, a zone of very high porosity between 0.4 and 1.1 m, underlain by a less conductive layer, is a probable route for interflow during, and for a few hours after, heavy and prolonged rainfall.

    In order to generate well-based design decisions on reinforcement of landslide slopes and road embankment slopes, a system of combined geotechnical analysis of geological conditions is suggested which includes topographic and geo-physical survey, and laboratory studies of soils using infra-red spectroscopy methods. Calculations of slopes' deflected modes are carried out with taking into account elastic and elasto-plastic behavior of soil, and the presence of supporting man-made constructions. Results of the application of the system suggested may be used as criteria for the classification of landslide slopes along permanent ways according to the degree of danger when used for transportation.

    Pressurized rail tank cars transport large volumes of volatile liquids and gases throughout the country, much of which is hazardous and/or flammable. These gases, once released in the atmosphere, can wreak havoc with the environment and local populations. We developed a system which can non-intrusively and non-invasively detect and locate pinhole-sized leaks in pressurized rail tank cars using acoustic sensors. The sound waves from a leak are produced by turbulence from the gas leaking to the atmosphere. For example, a 500 μm hole in an air tank pressurized to 689 kPa produces a broad audio frequency spectrum with a peak near 40 kHz. This signal is detectable at 10 meters with a sound pressure level of 25 dB. We are able to locate a leak source using triangulation techniques. The prototype of the system consists of a network of acoustic sensors and is located approximately 10 meters from the center of the rail-line. The prototype has two types of acoustic sensors, each with different narrow frequency response band: 40 kHz and 80 kHz. The prototype is connected to the Internet using WiFi (802.11g) transceiver and can be remotely operated from anywhere in the world. The paper discusses the construction, operation and performance of the system.

    The zones of thawed ground in the permafrost area are most dangerous from engineer-geologist effect point of view. Detection of such zones, as making forecast of their movement is the main task of engineer-geologist survey been held in railway industry. This paper presents general issues concerning railway construction and operation in permafrost areas. Comprehensive geophysical methods to monitor the development of thawed soils are considered in detail. The main physical parameters which help define permafrost and thawed soil patches are described. Author of current paper pointed out main factors, allowing predicting potential areas of development of thawed grounds. They offered set non-destructive methods:GPR investigations, seismic survey and elec-tric exploration. Whole sets of geophysical data:electric resistivity, velocity of S-wave and P-wave (and their correlation), allow us with high confidence specify characteristics and state of soil either under the line of road, or near it. At the same time the meth-od allows to predict direction of further development of thawed ground area.

    The construction of railway lines usually has a negative effect on the natural environment: habitats are destroyed, collisions with trains cause deaths, and the noise and vibrations associated with rail traffic disturb the lives of animals. Cases are known, however, where the opposite holds true: a railway line has a positive effect on the fauna in its vicinity. In this study, we attempted to define the influence of a busy railway line on a breeding community of woodland birds. Birds were counted using the point method at 45 observation points located at three different distances (30, 280, 530 m) from the tracks. At each point, we determined the habitat parameters and the intensity of noise. In total, 791 individual birds of 42 species were recorded on the study plot. Even though the noise level fell distinctly with increasing distance from the tracks, the abundance of birds and the number of species were the highest near the railway line. Moreover, insectivorous species displayed a clear preference for the vicinity of the line. The noise from the trains did not adversely affect the birds on the study plot. The environmental conditions created by the edge effect meant that the birds preferred the neighborhood of the tracks: the more diverse habitats near the tracks supplied attractive nesting and foraging niches for many species of birds. Trains passing at clear intervals acted as point sources of noise and did not elicit any negative reactions on the part of the birds; this stands in contrast to busy roads, where the almost continuous flow of traffic in practice constitutes a linear source of noise.

  11. Strain-Based Evaluation of a Steel Through-Girder Railroad Bridge

    Directory of Open Access Journals (Sweden)

    Andrew N. Daumueller

    2012-01-01

    Full Text Available In the state of New Mexico (USA, passenger rail began in 2008 between Belen and Santa Fe on the Rail Runner, following the acquisition of about 100 miles of existing rail and related infrastructure. Many of the bridges on this route are over 100 years old and contain fatigue prone details. This study focuses on a steel through-girder bridge along this corridor. To accurately evaluate these structures for load carrying capacity and fatigue, an accurate analytical model is required. Accordingly, four models were developed to study the sensitivity of a bridge in New Mexico to floor-system connection fixity and the ballast. A diagnostic load test was also performed to evaluate the accuracy of the finite-element models at locations of maximum moments. Comparisons between the simulated and measured bridge response were made based on strain profiles, peak strains, and Palmgren-Miner’s sums. It was found that the models including the ballast were most accurate. In most cases, the pinned ended models were closer to the measured strains. The floor beams and girders were relatively insensitive to the ballast and end conditions of the floor-system members, whereas the stringers were sensitive to the modeling of the ballast.

  13. Abrasive wear of railway sections of steel with a different pearlite morphology in railroad switches

    Directory of Open Access Journals (Sweden)

    J. Herian

    2010-11-01

    Full Text Available Purpose: The analyse of pearlite morphology changes as a result of hot rolling process and isothermal annealing.Design/methodology/approach: Physical modelling of isothermal annealing for a transition point of 520-620°C was carried out using a Gleeble simulator. A scanning electron microscope was used for a quantitative evaluation of the microstructure. Tests of resistance to abrasive wear were carried out at the Amsler stand.Findings: The obtained test results confirm that these methods can be effectively used in shaping the pearlitic structure and properties of the steel.Practical implications: In physical modelling of tests of resistance to abrasive wear for the steel grade R260 after hot rolling and isothermal annealing it has been proved that this feature is a function of the steel structure and properties in the given operation conditions. The resistance to abrasive wear of steel R260 with a pearlitic structure and different pearlite morphology decreases with the increase of load and slide.Originality/value: An advantageous pearlitic morphology of steel (block sections with interlamellar distance in the order of 0.12-0.13 μm, ensuring hardness of about 340-350 HB, is facilitated by a hot rolling process combined with isothermal annealing.

    2012-01-01

    In a world where communication and information sharing are at the heart of our business, the terminology needs are most pressing. It has become imperative to identify the terms used and defined in a consensual and coherent way while preserving linguistic diversity. To streamline and strengthen the process of acquisition, representation and exploitation of scenarii of train accidents, it is necessary to harmonize and standardize the terminology used by players in the security field. The research aims to significantly improve analytical activities and operations of the various safety studies, by tracking the error in system, hardware, software and human. This paper presents the contribution of ontology to modeling scenarii for rail accidents through a knowledge model based on a generic ontology and domain ontology. After a detailed presentation of the state of the art material, this article presents the first results of the developed model.

    Meeker, F L; Barr, R A

    1989-06-01

    Observations were made of 57 drivers who approached a rural rail grade crossing in the presence of activated warning flashers signalling an approaching train. Two thirds of the drivers crossed the tracks in front of the approaching trains. All but four drivers, however, slowed perceptibly or stopped prior to crossing. The probability of crossing was seen to vary reliably with distance of the trains from the crossing and the time available to cross (safety margin). It was concluded that, as a group, the drivers' decision to cross was a considered one that was based on an accurate perception of available evidence. PMID:2736022

  7. Railroad inspection based on ACFM employing a non-uniform B-spline approach

    Science.gov (United States)

    Chacón Muñoz, J. M.; García Márquez, F. P.; Papaelias, M.

    2013-11-01

    The stresses sustained by rails have increased in recent years due to the use of higher train speeds and heavier axle loads. For this reason surface and near-surface defects generate by Rolling Contact Fatigue (RCF) have become particularly significant as they can cause unexpected structural failure of the rail, resulting in severe derailments. The accident that took place in Hatfield, UK (2000), is an example of a derailment caused by the structural failure of a rail section due to RCF. Early detection of RCF rail defects is therefore of paramount importance to the rail industry. The performance of existing ultrasonic and magnetic flux leakage techniques in detecting rail surface-breaking defects, such as head checks and gauge corner cracking, is inadequate during high-speed inspection, while eddy current sensors suffer from lift-off effects. The results obtained through rail inspection experiments under simulated conditions using Alternating Current Field Measurement (ACFM) probes, suggest that this technique can be applied for the accurate and reliable detection of surface-breaking defects at high inspection speeds. This paper presents the B-Spline approach used for the accurate filtering the noise of the raw ACFM signal obtained during high speed tests to improve the reliability of the measurements. A non-uniform B-spline approximation is employed to calculate the exact positions and the dimensions of the defects. This method generates a smooth approximation similar to the ACFM dataset points related to the rail surface-breaking defect.

  3. Investigation of differential movement at railroad bridge approaches through geotechnical instrumentation

    Institute of Scientific and Technical Information of China (English)

    2012-01-01

    Railway transitions experience differential movements due to differences in track system stiffness,track damping characteristics,foundation type,ballast settlement from fouling and/or degradation,as well as fill and subgrade settlement.This differential movement is especially problematic for high speed rail infrastructure as the 'bump' at the transition is accentuated at high speeds.Identification of different factors contributing towards this differential movement,as well as development of design and maintenance strategies to mitigate the problem is imperative for the safe and economical operation of both freight and passenger rail networks.This paper presents the research framework and initial instrumentation details from an ongoing research effort at the University of Illinois at Urbana-Champaign.Three bridge approaches experiencing recurrent geometry problems were instrumented using multidepth deflectometers (MDDs) and strain gages to identify different factors contributing to the development of differential movements.

    2009-10-01

    Current collection is a key issue in modern electrical railway, and its performances are mainly determined by the pantograph/catenary interactions. Whilst being the less investigated topic, the pantograph/catenary mechanical interface is the most crucial one. Many incidents and traffic interruptions are due to degraded, or even damaged, electrical contacts between current collectors and contact wires. During the 6th European Framework Program (FP6) CATIEMON project (CATenary InterfacE MONitoring), both FBG-based sensors and systems dedicated to the pantograph/catenary interaction monitoring - directly from the high voltage contact wire - have been developed and tested. This paper describes their design and installation but also results coming from field-tests. It highlights their advantages for the railway stakeholders and end-users in term of train operation enhancement.

  8. Coupled Mooring Systems for Floating Wind Farms

    In this work the feasibility of an integrated catenary loose mooring system for offshore floating wind turbines is investigated. The dynamic behavior of different wind farm layouts is analyzed employing the equation of motion. It will be especially sought after potential resonance problems. The equation is solved in frequency domain, using a linearized stiffness matrix, as well as in time domain. Time-domain simulation is done by using a quasi-static model, where the catenary equa...

    2005-01-01

    Loss of access to critical habitats is a key wildlife concern, particularly for species listed for protection by state and federal agencies. Rail corridors pose unique design challenges by virtue of the need to avoid abrupt changes in track curves and grade in the right of way (ROW). Spotted turtles (Clemmys guttata) are particularly vulnerable to habitat fragmentation due to their limited mobility and dependence on a diversity of specific foraging, nesting, and aestivation habitats. Spotted ...

    OpenAIRE

    Bollinger, William

    2012-01-01

    Peru's importance to the United States in the nineteenth century has been underappreciated because there were few instances of sharp conflict between the two nations. But, beginning with U.S. export of coarse cloth from new cotton mills just after Peruvian independence, continuing during the influence of Peruvian guano on U.S. "scientific agriculture," and then in the period of Peru's extraordinary effort to build trans-Andean railways, Peru exercised important influence on U.S. economy and ...

  15. Dynamic analysis of a container with a single layer of drums mounted on a railroad car suffering collision

    International Nuclear Information System (INIS)

    Dynamic analysis has been performed with a new Type of 20' box container qualified as an industrial package Type 2 and 3 and as a Type A container. In the model for a numerical collision experiment the container was partially loaded with 21 x 1000 kg drums, arranged along three parallel rows forming a single layer. One of the aims in the container development was to achieve a system that could transport cargoes with a variable number of drums stacked in changeable configurations, while ensuring the safety of the container for dynamic forces that could arise during normal conditions of transport. This led to the design of an interchangeable tray for the drums that can easily be handled and loaded into the container, together with passive restraining devices that prevent this assembly from moving inside the container when subjected to dynamic forces. The container system is designed to withstand accelerations of up to 6g in the longitudinal direction. One result of the calculations is that stiff support systems are not capable of absorbing the impact forces once the critical velocity of 10 km.h-1 is exceeded, since the forces quickly grow beyond even the design strength of a new 20' box container of 500 kN. In comparison the design strength of today's IP 2/IP 3 container is only approximately 80 kN. In the numerical experiments, it was observed that a soft cushioning support tray system like the one developed by CORROBESCH/STM has excellent shock absorbing characteristics. By contrast, a rigid support system, or worse, no support system at all, is likely to produce impact forces at normal conditions of transport capable of endangering the container walls. (author)

  17. Contribution of Case Based Reasoning (CBR) in the Exploitation of Return of Experience. Application to Accident Scenarii in Railroad Transport

    CERN Document Server

    Maalel, Ahmed

    2012-01-01

    The study is from a base of accident scenarii in rail transport (feedback) in order to develop a tool to share build and sustain knowledge and safety and secondly to exploit the knowledge stored to prevent the reproduction of accidents / incidents. This tool should ultimately lead to the proposal of prevention and protection measures to minimize the risk level of a new transport system and thus to improve safety. The approach to achieving this goal largely depends on the use of artificial intelligence techniques and rarely the use of a method of automatic learning in order to develop a feasibility model of a software tool based on case based reasoning (CBR) to exploit stored knowledge in order to create know-how that can help stimulate domain experts in the task of analysis, evaluation and certification of a new system.

    In order to investigate the damping characteristics of railway-overhead-wire systems, we propose herein an approach based on the continuous wavelet transform (CWT) and two existing formulas concerning Rayleigh damping coefficients (RDCs). In the proposed process, the displacement histories of a real catenary are first obtained by using a set of noncontact photogrammetric devices, following which an exclusive catenary damping ratio related to the first dominant modal component in the catenary response is identified through a complex Morlet CWT. Thereafter, iterative finite-element analysis is conducted to find the optimal RDCs, which involves using two related formulas and the similarity between the catenary displacements obtained by simulation and experimentation. The results of our study demonstrate that this combined approach is constructive, especially for structures with closely spaced modes, such as catenaries. For the case studied herein, the catenary modal damping ratio at 1.19 Hz is approximately 1%, and the mass and stiffness proportional Rayleigh damping coefficients are approximately 0.02845 and 0.00274, respectively.

    2005-02-01

    A feasibility study for amplitude and frequency vibration measurement in aerial electricity transmission cable has been made. This study was carried out incorporating a fringe projection method for the experimental part and horizontal taut string model for theoretical one. However, this kind of model ignores some inherent properties such as cable sag and cable inclination. Then, this work reports advances on aeolic vibration considering real cables. Catenary and sag are considered in our theoretical model in such a way that an optical theodolite for measuring has been used. Preliminary measurements of the catenary as well as numerical simulation of a sagged cable vibration are given.

  12. Railroad accident report - derailment of Southern Pacific Transportation Company Train no. 01-BSMFF-05 carrying radioactive material at Thermal, California, January 7, 1982

    International Nuclear Information System (INIS)

    About 9:50 p.m., P.s.t., on Thursday, January 7, 1982, Southern Pacific Transportation Company freight train No. 01-BSMFF-05, derailed 14 cars at Thermal, California, while traveling about 57 miles per hour on the tangent single main track. Four transients riding on the train were seriously injured, a fifth transient died as a result of injuries. No crewmembers were injured as a result of the accident. The presence of radioactive material in the derailed Trailer-On-Flat-Car train was discovered about 1 hour after the accident occurred, resulting in the handling of the emergency response effort as a serious radiological emergency. Accurate information regarding the precise nature of the radioactive material shipment was not available at the accident site until about 5 hours after the derailment occurred; at that time radiological emergency procedures were terminated. The National Transportation Safety Board determines that the probable cause of this accident was the inadequate company evaluation of defect data which should have indicated that the rail in the vicinity of the derailment was approaching service life limit for main track use and the consequent failure of the company to initiate an accelerated inspection program to detect incipient fatigue fractures of the rail

    Since its development in 1974 the Q-system for classifying rock masses has readily been used for dimensioning support measures in underground excavations in Norway and internationally. The Q-system, as it was originally developed, is based on 6 parameters where two and two make up ratios describing degree of fracturing, frictional conditions along joints and stress conditions in the rock mass. During the past decade there has been an increasing interest in investigating any other fields ...

    The study of 64 welders employed at automated work stands in the railway car factory conducted in 1989 and 1990 has shown that the psychomotor efficiency level in the examined workers (except for a few cases) was normal. The psychomotor efficiency of the welders studied depended on their age, work day phase and, to a small degree, on the detected biochemical and toxicological disorders. PMID:1453944
