2015-12-01

Full Text Available In modern society, patriotism is manifested in all spheres of human life and it is understood as a love for the motherland and its people, as a sense of duty and pride for the country, a sense of honor and personal dignity, personal responsibility for occurring events, devotion to the country and its people. Patriotism is a complex concept including patriotic feelings of an individual. In the article, the peculiarities of the manifestation of patriotic feelings in high school students are analyzed on the basis of the system-functional approach. The study involved a group of senior students of secondary comprehensive school, a group of the representatives of the Ministry of Emergency Situations and cadets of a Cadet Corps. Statistically significant differences in sixteen variables characterizing manifestation of patriotic feelings were obtained in the group of cadets, the differences were observed in degrees of manifestation of both harmonic and inharmonic variables. High values were obtained for the variables of the reflective-evaluative component. The personal difficulties have got higher values which indicates a serious and responsible approach of cadets to the manifestation of patriotic feelings. These results were used to formulate correction programs aimed at the harmonization and development of patriotism among representatives of different age groups

Political ideology and American intergroup discrimination: A patriotism perspective.

Science.gov (United States)

L Hoyt, Crystal; Goldin, Aleah

2016-01-01

In this research we demonstrate the powerful role of ingroup favoritism, rather than hostility, in American intergroup biases. Specifically, we take a novel perspective to understanding the relationship between political ideology and discrimination against ethnic-minority Americans by focusing on the role of patriotism. Across three studies, we show that political ideology is a strong predictor of resource allocation biases, and this effect is mediated by American patriotism and not by prejudice or nationalism. Conservatives report greater levels of patriotism than liberals, and patriotism is associated with donating more to American, as opposed to ethnic-minority American, organizations. We further show that the link between patriotism and partiality to the national group is mediated by stronger "American = White" associations. These findings have important implications for intergroup relations and diversity-related policy issues in the United States.

The article sees the rise of ‘patriotic journalism’ in recent Zimbabwe as representing something qualitatively different from any other forms of patriotism or journalism. The ‘patriotic journalism’ practiced by Jonathan Moyo’s ministry from 2000-5, was narrowly defined and destructive. At a time when Socialism had been abandoned, education and welfare undermined, patriotic journalism emerged as the Zimbabwean government’s last resort. The article unequivocally states that Zimbabweans ought no...

Kagan, I; Itzhaki, M; Melnikov, S

2017-12-01

To examine the influence of nurses' patriotism and organizational commitment on their intention to report for work in a national emergency, in Israel. Healthcare systems need to forecast the number of staff likely to report for work in emergencies and mass casualty events. Patriotism and nurses' commitment to work are factors that prompt nurses to leave their families and report for duty, even knowing that they are putting themselves in danger. However, patriotism as a variable that might affect nurses' intention to report for work in emergencies has not been investigated. A descriptive, cross-sectional survey was used with a convenience sample of 152 registered nurses. Descriptive statistics, Pearson correlation coefficients and t-tests were used to analyse the data. To examine the unique contribution of the independent variables to the explanation of the dependent variable - intention to report to work in emergency - multiple regression analysis was performed. Significant positive correlations were found between age, seniority and research variables (organizational commitment, patriotism and intention to report for emergency work). Patriotism differed by gender, ethnicity and religion. Patriotism and gender explained 23% of the variance regarding intention to report for emergency duty, with patriotism playing a major role. Patriotism has religious and cultural dimensions. Cultural differences explain the discrepancy in organizational commitment between Israeli-born nurses and immigrants. Emergency training drills for nurses should feature discussions on universal ethical principles in emergency planning, preparedness and responses. The willingness of ethnic/religious minorities and immigrants to report for work in a national emergency should be taken into consideration in healthcare system disaster planning, so as to lessen the impact of disparate patriotism. © 2017 International Council of Nurses.

US patriotism and ideologies of group dominance: a tale of asymmetry.

Science.gov (United States)

Peña, Yesilernis; Sidanius, Jim

2002-12-01

Using a random sample (N = 405) of White and Latino Americans from Los Angeles County, the authors explored whether there is an asymmetrical relationship between U.S. patriotism and two different dimensions of social dominance orientation: group antiegalitarianism and group dominance. Although there was no evidence of asymmetry in the relationship between U.S. patriotism and group antiegalitarianism, there was evidence of consistent asymmetry in the relationship between U.S. patriotism and group dominance. Among Whites (the dominant North American ethnic group) and depending on demographic variables such as age, education, income, and gender, the greater the respondents' tendency to subordinate "inferior groups," the greater their level of U.S. patriotism. In contrast, among Latino Americans (the major subordinate group in Southern California), the opposite trend was found. Here, higher levels of group dominance orientation were associated with lower levels of U.S. patriotism. The theoretical implications of these findings are discussed.

Climate patriots? Concern over climate change and other environmental issues in Australia.

Science.gov (United States)

Tranter, Bruce; Lester, Libby

2017-08-01

Echoing the anti-pollution and resource conservation campaigns in the United States in the early-to-mid-twentieth century, some scholars advocate mobilising support for environmental issues by harnessing the notion of environmental patriotism. Taking action to reduce the impact of global warming has also been cast as a patriotic cause. Drawing upon quantitative data from a recent national survey, we examine the link between patriotism and environmental attitudes in Australia, focussing upon climate change. We find that patriotism has a largely neutral association with concern over environmental issues, with the exception of climate change and, to a lesser extent, wildlife preservation. Expressing concern over climate change appears to be unpatriotic for some Australians. Even after controlling for political party identification and other important correlates of environmental issue concerns, patriots are less likely than others to prioritise climate change as their most urgent environmental issue and less likely to believe that climate change is actually occurring.

Lucas and patriotism in mid-eighteenth century Ireland.

Science.gov (United States)

Magennis, E

2015-09-01

This paper explores the extent to which Charles Lucas can be described as a typical patriot in mid-eighteenth century Ireland. The political ideas and practices of Irish patriots of the mid-eighteenth century belong to broad spectrum including opposition MPs, anti-Catholic rhetoricians and questioners of the usefulness of the penal laws, economic pamphleteers and individuals interested in recovering Ireland's history and antiquities. Lucas was significant in that he sometimes inhabited all of these political and cultural guises, but also mobilised the Dublin public in political campaigns and was striking in his voluminous output in newspapers and pamphlets.

Full Text Available This article discuses about The Indonesian National Defense Forces (Tentara Nasional Indonesia/TNI who has been experiencing a shift from praetorian military to professional military because of fundamental change within Indonesian society after the end of the Soeharto’s regime in 1998 which is followed by a transition of power from New Order to reformed government. That shift can be seen through some issues related to territorial institutions, military business, and relation between TNI and The Ministry of Defense (Departemen Pertahanan. This paper argues that that shift and its related issues can be explained by patriot professional military thesis. This thesis combines certain aspects of Huntington’s old professionalism and Stepan’s new professionalism. As a patriot professional military TNI has professional characteristics as well as strong commitment to take a part in nondefense tasks according to decisions of civilian government. To become patriot professional military TNI needs to develop itself in a condition with objective civilian control that promotes military professionalism, and highly respects the civilian supremacy. This paper approached its problem with sociology of military, and made its inquiry with qualitative method. Tulisan ini membahas fenomena TNI yang tengah mengalami pergeseran dari militer praetorian menuju militer profesional seiring terjadinya perubahan mendasar dalam masyarakat Indonesia karena peralihan kekuasaan dari Orde Baru ke pemerintahan Reformasi pasca-berakhirnya pemerintahan Soeharto pada 1998.

Can patriotism justify killing in defense of one’s country?

Directory of Open Access Journals (Sweden)

Pavković Aleksandar

2007-01-01

Full Text Available Cosmopolitan liberals would be ready to fight - and to kill and be killed for the sake of restoring international justice or for the abolition of profoundly unjust political institutions. Patriots are ready to do the same for their own country. Sometimes the cosmopolitan liberals and patriots would fight on the same side and sometimes on the opposite sides of the conflict. Thus the former would join the latter in the defense of Serbia against Austria-Hungary (in 1914 but would oppose the white Southerner patriots in the American Civil War (in 1861. In this paper I argue that fighting and killing for one’s country is, in both of those cases, different from the defense of one’s own life and the lives of those who cannot defend themselves. Killing for one’s country is killing in order to fulfill a particular political preference. The same is the case with fighting for the abolition of a profoundly unjust political institution. It is not amoral or immoral to refuse to kill for any one of these two political preferences because there is no reason to believe that either political preference trumps our moral constraints against killing.

Between Patriotism and Far-Right Extremism: A Case of Youth Activism in Matica slovenská

2015-06-01

Full Text Available This case study discusses a youth branch of Matica slovenská, a pro-Slovak culture organization. It is based on in-depth research of the structure of the organization and it focuses on basic characteristics of functioning of this social movement such as funding, membership base, political orientation, civic engagement, patriotic activities and also the causes of negative media presentation. Presented material pointed to a thin boundary between the perception of positive manifestations of patriotism and at the same time negative (even extremist connotations of such manifestations in Slovak society. This duplicate perception of patriotic activities is reflected not only in polarization of opinion in society but also on the level of political, media and public communication. Thus, the article is a small probe from the scene of youth activism with an ambition to point out to such a diverse perception of patriotic organizations/activities in present-day Slovak society.

Falcons' patriotism: 'One state, one nation, falconry'

Full Text Available This work shows the results of the research which goal was to find, systemize and critically overview the information on a patriotic role of the falcon's organization and its members, having in mind reflex of all social-historical events in the period from the birth of falcons till the end of the Second World War. Social, economic, cultural, and in the first place political situations significantly influenced the character of falcons' organizational influence. In the stormy past falcon shared destiny if its state and nation and therefore this body-exercising organization grew in time into falcons' organization. Falcon's goal besides body exercising was aiming higher goals: moral and cultural revival, national freedom, nation's unity. With enlightening of falcon membership a strong and versatile person with the sense for national affiliation, freedom and social equality was developed. Falcons' democracy, patriotism, philanthropy, belief in ideals, contributed to falcons' reputation in population, which significantly influenced accomplishment of one of the main goals of the falcon movement - forming of the united country and accomplishment of higher range in military, economical, social and cultural plan. Research results point out that during the First World War a falcon was a supporting unity of nations into one state. Therefore falcons were convicted to prison, persecution and internment, execution and hanging at 'high treason' court processes. Patriotic spirit and strong national as well as Yugoslav sense followed falcons later on in an uncompromising battle with separatist and pro - fascist power during more frequent strokes on state's integrity. In the first days of occupation, falconry represented a cohesion and mobilization factor in people. At the beginning of the 1940 falconry counted 350.000 members, which was considered 'the second echelon' of defense of the Kingdom of Yugoslavia.

Some ‘indicators’ to ‘measure’ patriotism in the contemporary world

Directory of Open Access Journals (Sweden)

Trotsuk Irina V.

2017-01-01

Full Text Available Today there are diverse trends (such as government’s intervention into the private lives of people, reduction of state’s support and impact in the social sphere, and globalization that makes the world smaller that complicate the sociological study of patriotism in a ‘traditional’ way – as a value orientation ‘measured’ by simple questions about one’s knowledge, feelings, actions, and self-identification. Thus, it is necessary to identify several frameworks for the empirical study of patriotism. The first ‘dimension’ is traditional ‘patriotic mood’ – a set of stable cognitive, affective and behavioral value orientations. The second ‘dimension’ consists of different components of the social well-being associated primarily with the estimates of life in the country. The third ‘dimension’ consists of persistent stereotypes of the neighboring and other countries in the geopolitical context. The fourth ‘dimension’ is a result of the political decisions considering national security issues. Russia’s political leaders connect food trade to national security; therefore, ‘food insecurity’ is to a great extent manufactured for political reasons to bolster national security or (food nationalism.

A symmetrical rail accelerator

International Nuclear Information System (INIS)

Igenbergs, E.

1991-01-01

This paper reports on the symmetrical rail accelerator that has four rails, which are arranged symmetrically around the bore. The opposite rails have the same polarity and the adjacent rails the opposite polarity. In this configuration the radial force acting upon the individual rails is significantly smaller than in a conventional 2-rail configuration and a plasma armature is focussed towards the axis of the barrel. Experimental results indicate a higher efficiency compared to a conventional rail accelerator

Electrodynamic wear of rails in high current density rail gun discharges

International Nuclear Information System (INIS)

Edwards, W.T.; Caldwell, S.G.

1984-01-01

Significant advances in high current, high speed power sources, has in recent years allowed rail guns to produce very high velocity (> 10 km/sec) macroscopic particles (> 1/10 grams). A continuing problem is the structural integrity of the components under these loadings and in particular, the rail wear due to the high current density plasma contacts. In this investigation a small bore rail gun (6x5 mm) was used with a 10.6 kjoule capacitor energy source to examine the modes of rail damage. The rails were constructed of 110 copper base material. These rails were used in an uncoated condition and also with plasma sprayed coatings of W and W/WC. The resulting surface wear was characterized by standard metallurgical techniques and analyzed for the various coatings

They also showed positive perception on independence day television commercials, as high number of respondents have agreed that the concept, theme and art direction of television commercial about love and live in unity without racism will be the style of benchmark for the future style of direction towards producing television commercial for Independence Day and are considered vital to instill patriotism towards the nation.

Impact of the rail-pad multi-discrete model upon the prediction of the rail response

Science.gov (United States)

Mazilu, T.; Leu, M.

2017-08-01

Wheel/rail vibration has many technical effects such as wear of the rolling surfaces, rolling noise, settlement of the ballast and subgrade etc. This vibration is depending on the rail pad characteristic and subsequently, it is important to have an accurate overview on the relation between the rail pad characteristic and the level of the wheel/rail vibration. To this end, much theoretical and experimental research has been developed in the past, and for the theoretical approach the track model, in general, and, particularly, the rail pad model is of crucial importance. Usually, the rail pad model is discrete model one, neglecting the length of the rail pad. This fact is questionable because the sleepers span is only 4 times the rail pad length. Using the rail pad discrete model, the rail response is overestimated when the frequency of the excitation equals the pinned-pinned resonance frequency. In this paper, a multi-discrete model for the rail pad, consisting in many Kelvin-Voigt parallel systems, is inserted into an analytical model of the track. The track model is reduced to a rail taken as infinite Timoshenko beam, discretely supported via rail pad, sleeper and ballast. The influence of the number of Kelvin-Voigt systems of the rail pad model on the rail response is analysed.

Determination of the primary technical parameters of the test bench for controlling the temperature of rails and rail bars of continuous welded rail

Directory of Open Access Journals (Sweden)

Tertychnyi Vitalii

2017-01-01

Full Text Available One of the most important factors determining the reliability and safety of operation of the continuous welded rail track is the temperature of the rails. All conditions of laying, repair and maintenance of the track during the entire cycle of rails operation depend on it. The existing rail temperature monitoring method does not take into account a few significant factors and that leads to significant errors in determining the actual temperature of the rail bar. The authors propose a new rail temperature measurement method on a special test bench which maximally simulates possible environmental operating conditions for the rail bars, the profile of the roadway (embankment or cut, as well as the actual spatial latitude and meridian location of the rail slabs. At the bench, the studied rails are fastened with the help of rail braces on half ties, in the ballast bed, with sizes in accordance with the existing reference documents. At the first stage, the most common KB-65 intermediate fastener for the continuous welded rail in Ukraine will be used, while in subsequent stages KPP-5 fastening will be used.

Preliminary rail access study

International Nuclear Information System (INIS)

1990-01-01

The Yucca Mountain site, located on the southwestern edge of the Nevada Test Site, is an undeveloped area under investigation as a potential site for nuclear waste disposal by the US Department of Energy. The site currently lacks rail service and an existing rail right-of-way. If the site is suitable and selected for development as a disposal site, rail service is desirable to the Office of Civilian Radioactive Waste Management Program because of the potential of rail to reduce number of shipments and costs relative to highway transportation. This preliminary report is a summary of progress to date for activities to identify and evaluate potential rail options from major rail carriers in the region to the Yucca Mountain site. It is currently anticipated that the rail spur will be operational after the year 2000. 9 refs., 13 figs., 2 tabs

Implications of rail electrodynamics

International Nuclear Information System (INIS)

Rolader, G.E.; Jamison, K.A.

A model is developed to investigate possible effects of rail electrodynamics on the performance of railguns. This model describes the oscillatory nature of the rail motion in response to the Lorentz force and the compressive restoration force of material which is behind the rails. In this simple model the rails are found to oscillate with a frequency of β. The rail dynamic behavior induces local electric fields. The authors investigate the significance of these electric fields on stationary particles (lab frame) and on particles moving at the velocity of the plasma/projectile system (projectile frame)

Identification and prioritization of rail squat defects in the field using rail magnetisation technology

Science.gov (United States)

Kaewunruen, Sakdirat

2015-04-01

Inevitably, rail squats and studs are continuing to be a serious problem for railway organisations around the world in the 21st century. They are typically classified as the growth of any cracks that have grown longitudinally through the subsurface and some of the cracks propagating to the bottom of rails transversely, and have branched from initial longitudinal cracks with a depression of rail surface. The horizontal crack, which results in a depression of rail surface, induces increased maintenance level, more frequent monitoring, compromised rail testing (as the crack shields the signal echoes), and possible broken rails. This paper presents field investigations using a magnetised-rail testing device developed by MRX Technologies to identify and prioritise the rail squats. Most of the in situ squats were found on the high rail of the transition (variable-radius curved track), which is associated with rolling contact fatigue (RCF). This investigation highlights the field performance of the MRX's surface crack detection technology in comparison with the traditional ultrasonic method and detailed walking inspection. Visually, it was found in the field that the size of the RCF squats varies from very small to moderate. The predicted crack data were obtained by scanning the magnitised rails. The comparison of the actual crack depths (ultrasonic) and the predicted crack depths (MRX device) shows: • A possible correlation for small RCF/ squat cracks. • Poor interpretation of larger defects and welds. The field assessment also suggests some practical issues required for further development, including the detection of rail spalling, deep transverse crack, welding, and so on.

Bronze railing from Mediana

Directory of Open Access Journals (Sweden)

Vasić Miloje R.

2003-01-01

Full Text Available The hoard containing components of bronze railing was discovered in trench 7 during excavations at Mediana in 2000. Railing consists of cancelli and herms with busts of deities between them. Railing was constructed in such a way that it was possible to disassemble and reassemble it. Three cancelli one fragmented semicancellus cast together with herm and herms, one with bust of Aesculapius and other with bust of Luna. It could be concluded that railing consisted of two segments with passage between them. Male deities were represented on the left segment of the railing and female deities on the right segment. Detailed analysis revealed that Aesculapius as well as Luna bear strong mark of classical Greek and Hellenistic art, which experienced some kind of renaissance in the time of Constantine I. It is very probable that we can recognize the portrait of Faustina, Constantine’s wife in the portrait of Luna. According to the historical events the railing could have been produced before 325 AD when Constantine definitively accepted Christianity at Council of Nicaea. It is difficult to say where the railing had been produced. It had been most probably brought to Mediana during the stay of emperor Julian in Niš in 361. The sculptures found in one room of the villa with peristyle had probably been brought at the same time. The apse of triclinium of this villa had most likely been arranged as small shrine with bronze railing at its entrance. The railing was buried in 378 after battle of Adrianople and invasion of Goths in diocese Dacia.

Evacuation Route: Restoring the Railway Transportation of People During the Great Patriotic War

Directory of Open Access Journals (Sweden)

Potemkina Marina Nikolaevna

2015-11-01

Full Text Available The paper is devoted to the role of the railway transport in migration from the frontline to the Soviet rear during the Great Patriotic War. The research is based on the analysis of the published and archival documents, personal diaries, letters, memoirs, texts of interview with the people who lived through the evacuation. The methodological foundation of the research was based on the theoretical principles made by the Everyday History. Surge attack of the German troops and cruel occupational policy caused the necessity of evacuation of civilians to the Eastern regions of the country. The evacuation was both spontaneous and organized and helped to save millions of human lives. The lack of evacuation plans in case of a war, incompleteness of the railway transport renovation, transport routes destroyed by the enemy and the stream of refugees were among the main factors which complicated evacuation process. The conditions of transportation differed according to the time and the circumstances of the evacuation and a person’s position in social hierarchy. There were some problems during the evacuation, such as regulation of the rail service, sanitation of the carriages, nutrition system, psychological shock. People had to spend weeks in the carriages suffering from cold, hunger and diseases. During the evacuation a new alternative reality appeared with its rules and regulations which changed the concepts of tangible assets and moral values. The priority for any person was to survive, which meant to be independent and to do everything possible.

High speed rails. Fatigue behaviour

International Nuclear Information System (INIS)

Duart, J. M.; Pero-Sanz, J. A.; Verdeja, J. I.

2005-01-01

In recent years, passenger train speed and freight train load have increased to enhance efficiency of rail road transportation. These trends have increased the severity of rail service conditions, calling for rails with greater wear resistance, strength and fatigue behaviour. In the United Stated and Europe, track site weld rails are made entirely by aluminothermic process. This work describes the results of experimental study conducted on bending fatigue strength of plain rails and aluminothermic welded rails with preheating procedures (oxipropane and air-induced propane) approved by railways authorities. Compliance with the required fatigue strength shall be ascertained by 4 point pulsating bending test in accordance with European standards by aluminothermic welding in rails. The locati method, based in the empirical Miner's law about the cumulative damage on a fatigue tested material, allows, once known the Wohler curve of the welding process in use to settle the fatigue tensile limit at 50% with only one test. The values obtained at 2.10''6 cycles for plain rails (S f =353 MPa), oxipropane preheated aluminothermic weld rails (S f =225 MPa), and propane-air induced aluminothermic weld rails (S f =210 MPa) are very similar to those resulting from test method stated in the European Standard. From our point of view and due to its ease, speediness and savings, this is the most suitable test to check the quality and compare the aluminothermic processes in use. (Author) 15 refs

Optimization of wheel-rail interface friction using top-of-rail friction modifiers: State of the art

Science.gov (United States)

Khan, M. Roshan; Dasaka, Satyanarayana Murty

2018-05-01

High Speed Railways and Dedicated Freight Corridors are the need of the day for fast and efficient transportation of the ever growing population and freight across long distances of travel. With the increase in speeds and axle loads carried by these trains, wearing out of rails and train wheel sections are a common issue, which is due to the increase in friction at the wheel-rail interfaces. For the cases where the wheel-rail interface friction is less than optimum, as in case of high speed trains with very low axle loads, wheel-slips are imminent and loss of traction occurs when the trains accelerate rapidly or brake all of a sudden. These vast variety of traction problems around the wheel-rail interface friction need to be mitigated carefully, so that the contact interface friction neither ascents too high to cause material wear and need for added locomotive power, nor be on the lower side to cause wheel-slips and loss of traction at high speeds. Top-of-rail friction modifiers are engineered surface coatings applied on top of rails, to maintain an optimum frictional contact between the train wheels and the rails. Extensive research works in the area of wheel-rail tribology have revealed that the optimum frictional coefficients at wheel-rail interfaces lie at a value of around 0.35. Application of top-of-rail (TOR) friction modifiers on rail surfaces add an extra layer of material coating on top of the rails, with a surface frictional coefficient of the desired range. This study reviews the common types of rail friction modifiers, the methods for their application, issues related with the application of friction modifiers, and a guideline on selection of the right class of coating material based on site specific requirements of the railway networks.

Rail inspection of RCF defects

Directory of Open Access Journals (Sweden)

Z. Popović

2013-10-01

Full Text Available Rail defects due to rolling contact fatigue (RCF threaten the traffic safety around the world. That hazard is more distinct on railways without adequate maintenance strategy. Realization of interoperability of European railway network demands from every infrastructure manager to have a maintenance plan for the infrastructure subsystem. Besides that, this plan includes rail inspection and strategy against RCF defects. This paper emphasizes the importance of rail inspection and early detection of RCF because the most of RCF crack should be removed in rail grinding campaigns (preventive, cyclical and corrective activities during the whole rail service life.

A survey of wheel-rail contact models for rail vehicles

Science.gov (United States)

Meymand, Sajjad Z.; Keylin, Alexander; Ahmadian, Mehdi

2016-03-01

Accurate and efficient contact models for wheel-rail interaction are essential for the study of the dynamic behaviour of a railway vehicle. Assessment of the contact forces and moments, as well as contact geometry provide a fundamental foundation for such tasks as design of braking and traction control systems, prediction of wheel and rail wear, and evaluation of ride safety and comfort. This paper discusses the evolution and the current state of the theories for solving the wheel-rail contact problem for rolling stock. The well-known theories for modelling both normal contact (Hertzian and non-Hertzian) and tangential contact (Kalker's linear theory, FASTSIM, CONTACT, Polach's theory, etc.) are reviewed. The paper discusses the simplifying assumptions for developing these models and compares their functionality. The experimental studies for evaluation of contact models are also reviewed. This paper concludes with discussing open areas in contact mechanics that require further research for developing better models to represent the wheel-rail interaction.

Performance criteria for EM rail launchers with solid or transition armatures and laminated rails

International Nuclear Information System (INIS)

James, T.E.

1991-01-01

Velocity limitations of EM Rail Launchers with solid armatures due to the velocity skin-effect are assessed for a range of homogeneous materials (copper, aluminium, molybdenum and tungsten). Performance criteria as limited by armature melting in the region adjacent to the rail/armature contact surface and by rail surface melting are deduced analytically based on defined electro-thermal reference conditions. The performance criteria predict the reference transition velocity at which the solid contact surface changes to mainly a melted contact surface which is shown to be a fundamental property of the materials. The paper shows that the critical factors in obtaining a high transition velocity are a relatively high resistivity armature material combined with high temperature rail surface coatings. For example a transition velocity of >2.0 km/s for a molybdenum armature and a tungsten rail surface coating on a copper rail are predicted compared with <0.5 km/s for the aluminium/copper combination frequently used

Rail-induced Traffic in China

Directory of Open Access Journals (Sweden)

Nan He

2017-11-01

Full Text Available The rapid development of China’s railway has exerted an enormous influence on the intercity passenger transport structure in recent years. However, it has not satisfied the passengers’ travel demand due to induced traffic. This paper is committed to solving such issue, with the aim of satisfying the current travel demand, and of anticipating the demand of the predicted traffic growth over the next 20 to 30 years. The paper has considered the increase in rail passenger kilometres caused by the growth of rail kilometres as rail-induced traffic. Based on the concept and former research of induced traffic, the panel data of 26 provinces and 3 municipalities of China between the year 2000 and 2014 were collected, and the elasticity models (including elasticity-based model, distributed lag model, high-speed rail (HSR elasticity model and rail efficiency model have been constructed. The results show the importance of model formation incorporation of rail-induced traffic. It is better to get the correct value in divided zones with different train frequencies or incorporation rail efficiency in cities or provinces. The lag time and rail types also need to be considered. In summary, the results analysis not only confirms the existence of rail-induced traffic, but also provides substantial recommendations to train operation planning.

Rail abandonments in the South and their effect on NWPA rail shipments

International Nuclear Information System (INIS)

1988-02-01

The railroad industry will have a very critical role in the eventual shipping of commercial spent fuel and defense high-level waste as provided under the Nuclear Waste Policy Act of 1982 and the 1987 amendments. The transport of spent fuel is expected to be accomplished by rail from 19 of the South's 27 reactor sites to the proposed Yucca Mountain repository or possible monitored retrievable storage facility. The decline in total track availability, however, could significantly impact the federal government's transportation program. Particularly the situation of continuing abandonments may limit rail opportunities at numerous reactor locations. Commercial nuclear reactor sites have the unfortunate problem of not being located on Class I railroad mainline tracks. The reactor sites are generally located in areas with limited rail traffic and thus vulnerable to rail abandonment procedures. The general deregulation of the railroad industry under the Staggers Act of 1980 also assisted in making rail abandonment, through the Interstate Commerce Commission, a rather simple and quick process. The effects of deregulation, however, have provided alternatives to abandonment. In particular, the Staggers Act has led to an enormous surge in the growth of short line and regional railroads. Such railroads have been able to effectively operate rail lines which Class I railroads found unprofitable. The short lines and regionals were also encouraged to competitively negotiate contracts directly with shippers. While these railroads may help reduce the number of abandonment applications, they may also represent higher shipping costs. The South has experienced a great number of abandonments since the 1960's. Many of the abandonments have been significant in length and have affected areas near nuclear plants expected to ship by rail

Full Text Available Actual trends of worldwide railway transport development are characterized by increasing speed and growth of railway’s axels load. Increasing load together with transverse, longitudinal wheel displacement and braking on the rails results into heavy surface tension. One of many applications for bainitic steel is in railway transport for highly strength and wear resistant rails. Rail steel must be designed to be able to resist plastic deformation, wear, rolling contact fatigue, bending stress and thermal stress during rail welding process and rails resurfacing.

Fast rail corrugation detection based on texture filtering

Science.gov (United States)

Xiao, Jie; Lu, Kaixia

2018-02-01

The condition detection of rails in high-speed railway is one of the important means to ensure the safety of railway transportation. In order to replace the traditional manual inspection, save manpower and material resources, and improve the detection speed and accuracy, it is of great significance to develop a machine vision system for locating and identifying defects on rails automatically. Rail defects exhibit different properties and are divided into various categories related to the type and position of flaws on the rail. Several kinds of interrelated factors cause rail defects such as type of rail, construction conditions, and speed and/or frequency of trains using the rail. Rail corrugation is a particular kind of defects that produce an undulatory deformation on the rail heads. In high speed train, the corrugation induces harmful vibrations on wheels and its components and reduces the lifetime of rails. This type of defects should be detected to avoid rail fractures. In this paper, a novel method for fast rail corrugation detection based on texture filtering was proposed.

From Independence Day to Land of Plenty: Screening American Patriotism from German Émigré Perspectives before and after 9/11

Directory of Open Access Journals (Sweden)

Frank Mehring

2010-11-01

Full Text Available Independence Day and Land of Plenty are two tropes referring to the basis of American national identity: the Declaration of Independence with its guarantee of equal and inalienable rights and the promise of an inexhaustible abundance of resources. Independence Day and Land of Plenty are also two American feature films directed by German émigrés, the first being a science fiction blockbuster from 1996 by Roland Emmerich, the second an independent road movie from 2003 by Wim Wenders. Both films confront the issue of American patriotism albeit from different angles and at different times. Independence Day wholeheartedly embraces the American founding myths and translates them into a science fiction scenario. Wenders manoeuvres into an artistic space producing what I call patriotism of dissent. The films engage in a kind of dialectic dialogue on American patriotism. This article takes a close look at émigré perspectives on American patriotism before and after 9/11. By turning to the four patterns which political theorist Samuel P. Huntington identified as possible responses to the discrepancy between principles and practices of American democracy, I will analyse Independence Day as a filmic strategy to deny democratic gaps and Land of Plenty as a representative example of a moralistic reaction to democratic gaps. In the discourse of screening American patriotism from German émigré perspectives before and after 9/11, the work of Emmerich and Wenders exemplifies the spectrum of approaches to negotiate the fantasy of, desire for, and experience of American culture in the medium of film.

Rail Access to Yucca Mountain: Critical Issues

International Nuclear Information System (INIS)

Halstead, R. J.; Dilger, F.; Moore, R. C.

2003-01-01

The proposed Yucca Mountain repository site currently lacks rail access. The nearest mainline railroad is almost 100 miles away. Absence of rail access could result in many thousands of truck shipments of spent nuclear fuel and high-level radioactive waste. Direct rail access to the repository could significantly reduce the number of truck shipments and total shipments. The U.S. Department of Energy (DOE) identified five potential rail access corridors, ranging in length from 98 miles to 323 miles, in the Final Environmental Impact Statement (FEIS) for Yucca Mountain. The FEIS also considers an alternative to rail spur construction, heavy-haul truck (HHT) delivery of rail casks from one of three potential intermodal transfer stations. The authors examine the feasibility and cost of the five rail corridors, and DOE's alternative proposal for HHT transport. The authors also address the potential for rail shipments through the Las Vegas metropolitan area

Isamaalaulud ja okupatsioonirežiim – nostalgia, utoopia ja reaalsus. Estonian Patriotic Songs and the Occupational Regime – Nostalgia, Utopia and Reality

Directory of Open Access Journals (Sweden)

Kanni Labi

2012-04-01

Full Text Available Estonian knowledge of history emanates from the fact that constituting an independent nation has for the most part been nothing but a utopia, and was a reality for a relatively short time. When it comes to selfidentification though, the expression ’a singing people’ is often used by the Estonians to describe themselves. Nostalgia for freedom is reflected in the Estonian culture of almost all periods and is carried on by the singing tradition, where patriotic songs emerge independent of different musical tastes within a particular generation and form an important part of a common Estonian repertoire. Patriotic songs occupy a central place in several fields of Estonian culture: besides music culture also in popular culture,and literary history – the works of poetry which have gained the most popularity are those which when put to music have been the most widely spread among the people. The main part of the most popular Estonian patriotic songs are choral songs from the national awakening at the end of the 19th century. Despite the national programmes aiming to wipe out ‘bourgeois nationalism’, they were sung at the song festivals in the Soviet era and were published in song books, expressing the people’s nostalgia for freedom lost. After the end of the Second World War, there was an attempt at launching a kind of patriotic new creation, where patriotism was merged with Soviet pathos; the aim was to show that the people’s utopia was in fact communism, but not a single one of those songs made it into the people’s common repertoire. Only the patriotic songs composed in the 1980s during the so-called new national awakening reached a popularity comparable to that of the old songs. The discourse on ’Estonianness’ and the shaping of a matching repertoire under imperial Russian rule took place under very different circumstances than its preservation and development in the second half of the 20th century under Soviet occupation, but

A Current-Mode Common-Mode Feedback Circuit (CMFB) with Rail-to-Rail Operation

Science.gov (United States)

Suadet, Apirak; Kasemsuwan, Varakorn

2011-03-01

This paper presents a current-mode common-mode feedback (CMFB) circuit with rail-to-rail operation. The CMFB is a stand-alone circuit, which can be connected to any low voltage transconductor without changing or upsetting the existing circuit. The proposed CMFB employs current mirrors, operating as common-mode detector and current amplifier to enhance the loop gain of the CMFB. The circuit employs positive feedback to enhance the output impedance and gain. The circuit has been designed using a 0.18 μm CMOS technology under 1V supply and analyzed using HSPICE with BSIM3V3 device models. A pseudo-differential amplifier using two common sources and the proposed CMFB shows rail to rail output swing (± 0.7 V) with low common-mode gain (-36 dB) and power dissipation of 390 μW.

Remediation of the Department of Energy (DOE) Fernald site located north of Cincinnati will generate large quantities of low-level radwaste. This volume includes approximately 1,050,000 tons of material to be removed from eight waste pits comprising Operable Unit 1 (OU-1). The remedial alternative selected includes waste material excavation, drying and transportation by rail to a burial site in the arid west for disposal. Rail transportation was selected not only because rail transportation is safer than truck transportation, but also because of the sheer magnitude of the project and the availability of bulk rail car unloading facilities at a representative disposal site. Based upon current waste quantity estimates as presented in the Feasibility Study for OUI, a fully-loaded 47-car unit train would depart the Fernald site weekly for five years. This paper illustrates the steps taken to obtain agency and public acceptance of the Record of Decision for the remedy which hinged on rail transportation. A preliminary, but detailed, rail transportation plan was prepared for the project to support a series of CERCLA public meetings conducted in late 1994. Some of the major issues addressed in the plan included the following: (1) Scope of project leading to selection of rail transportation; (2) Waste classification; (3) Rail Company overview; (4) Train configuration and rail car selection; (5) Routing; (6) Safety; (7) Prior Notification Requirements (8) Emergency Response. A series of three public meetings identified a number of issues of prime concern to Fernald stakeholders. Following resolution of these issues during the public comment period, a Record of Decision (ROD) approving implementation of the rail transportation strategy was approved pending incorporation of EPA and State of Ohio comments on December 22, 1994

Rolader, G.E.; Jamison, K.A.; Villecco, R.A.; Graham, F.R.

1991-01-01

A model is developed to investigate rail electrodynamics in a plasma armature railgun. This model describes the rail motion in response to the transitory Lorentz force and the compressive restoration force from the material which is between the rails and the containment structure. In this model the distance between the rails is found to oscillate with a frequency of β. The magnetic field and the dynamic behavior of the rails induce local electric fields. We investigate the significance of these electric fields in the laboratory frame and in the projectile frame. In the lab frame, rail electrodynamics induces local electric fields which have maximums spaced behind the projectile at locations where βt p is an odd multiple of π, where t p is the time since the projectile has passed an axial location on the rails. When the projectile is accelerating, rail dynamics induce electric fields in the projectile frame which have maximums where βt p is an even multiple of π. As the projectile velocity increases, the locations of the peak voltages move farther behind the projectile. For the CHECMATE railgun, calculations indicate that the rail displacement is on the order of 2 mm, the rail velocity is on the order of 50 m/s, and the voltages induced in the projectile frame are on the order of 20--40 V

Homan, C.G.; Cummings, C.E.; Fowler, C.M.

1986-01-01

Superconducting augmentation consists of a superconducting coil operating in the persistent mode closely coupled magnetically with a normally conducting rail gun. A theoretical investigation of the effect of this system on a rail gun has shown that two benefits occur. Projectile velocities and launch efficiencies increase significantly depending on the magnetic coupling between the rail and augmentation circuits. Previous work evaluated an idealized system by neglecting energy dissipation effects. In this paper, the authors extend the analysis to include the neglected terms and show improved actual launch efficiencies for the SARG configuration. In this paper, the authors discuss details of projectile design in depth and present preliminary results of rail gun performance

Smith, Y.E.; Sawhill, J.M. Jr.; Cias, W.W.; Eldis, G.T.

1976-01-01

A laboratory study was conducted with the aim of developing an as-rolled rail of over 100 ksi (689 N/mm 2 ) yield strength. A series of compositions providing both pearlitic and bainitic microstructures was evaluated. A fine pearlitic structure was developed in a 0.73 percent C -- 0.83 percent Mn -- 0.16 percent Si -- 0.75 percent Cr -- 0.21 percent Mo steel by simulating the mill cooling rate of 132-lb/yd (65.5-kg/m) rail. Two 100-ton commercial heats were made of this approximate composition and processed into 132-lb/yd (65.5-kg/m) rail. Samples tested in the laboratory ranged from 109 to 125 ksi (750 to 860 N/mm 2 ) in yield strength. The chromium-molybdenum rails also exhibited excellent fracture toughness and fatigue properties. Sections of the rail were joined by both flash-butt welding and thermite welding. The hardness peaks produced in the flash-butt welds could be reduced by applying either a postweld current or an induction heating cycle. The high-strength chromium-molybdenum rails have been in service for over eight months in curved sections of an ore railway that carries over 55 million gross long tons per year. 7 tables, 18 figs

Computation of wheel-rail contact force for non-mapping wheel-rail profile of Translohr tram

Ji, Yuanjin; Ren, Lihui; Zhou, Jinsong

2017-09-01

Translohr tram has steel wheels, in V-like arrangements, as guide wheels. These operate over the guide rails in inverted-V arrangements. However, the horizontal and vertical coordinates of the guide wheels and guide rails are not always mapped one-to-one. In this study, a simplified elastic method is proposed in order to calculate the contact points between the wheels and the rails. By transforming the coordinates, the non-mapping geometric relationship between wheel and rail is converted into a mapping relationship. Considering the Translohr tram's multi-point contact between the guide wheel and the guide rail, the elastic-contact hypothesis take into account the existence of contact patches between the bodies, and the location of the contact points is calculated using a simplified elastic method. In order to speed up the calculation, a multi-dimensional contact table is generated, enabling the use of simulation for Translohr tram running on curvatures with different radii.

Welded joint zones are weak sections of the railway track for all traffic cases (in the case of high-speed traffic and heavy traffic). In the paper advantages and disadvantages of the basic ways of rails welding, which are widely used today, are considered: electrocontact and aluminothermic. Carefully selected mode of differentially thermally strengthened rails string will allow the process of correction after heat treatment to be minimized and internal residual compressive stresses to be kept. Particular attention should be paid to the method of rails welding, in which after rails welding during their cooling it is offered to perform quasi-isothermal exposure in the temperature range of fine structure formation by passing pulses of alternating electric current through the welded joint maintaining this temperature until the end of the transformation. The use of quasi-isothermal exposure at a temperature of 600 - 650 °C makes it possible to obtain a finely dispersed structure of the welded seam of rails without additional heat treatment.

Rail inspection using noncontact laser ultrasonics

International Nuclear Information System (INIS)

Kim, Nak Hyeon; Sohn, Hoon; Han, Soon Woo

2012-01-01

In this study, a noncontact laser ultrasonic system is proposed for rail defect detection. An Nd Yag pulse laser is used for generation of ultrasonic waves, and the corresponding ultrasonic responses are measured by a laser Doppler vibrometer. For the detection of rail surface damages, the shape of the excitation laser beam is transformed into a line. On the other hand, a point source laser beam is used for the inspection of defects inside a rail head. Then, the interactions of propagating ultrasonic waves with defects are examined using actual rail specimens. Amplitude attenuation was mainly observed for a surface crack, and reflections were most noticeable from an internal damage. Finally, opportunities and challenges associated with real time rail inspection from a high speed train are discussed

Model for predicting the frequency of broken rails

S. Vesković

2012-04-01

Full Text Available Broken rails can cause train delays, trains cancelations and, unfortunately, they are common causes of accidents. This affects planning of a resources, budget and organization of railway track maintenance. Planning of railway track maintenance cannot be done without an estimation of number of rails that will be replaced due to the broken rail incidents. There are many factors that influence broken rails and the most common are: rail age, annual gross tonnage, degree of curve and temperature in the time of breakage. The fuzzy logic model uses acquired data as input variables to predict the frequency of broken rails for the certain rail types on some Sections.

Applying the polluter-pays principle to rail: Environmental differentiation of rail access charges

Energy Technology Data Exchange (ETDEWEB)

Pons-Rigat, A.; Turro Calvet, M.; Ubalde Claver, Ll.

2016-07-01

Environmental charges to rail service operators are still at an early stage of implementation in Europe. Current schemes are dissimilar and most of them have a very limited scope or do not provide effective incentives to abate environmental impacts. This is due to several practical difficulties in implementing internalisation pricing schemes in the railway sector. The first difficulty arises from the lack of internalisation in other transport modes and the small competitive margin of railways. Increasing the overall level of rail charges could affect their survival. A second difficulty is due to the uncertainties in the valuation of external costs and in the establishment of the optimal level of charges. On top of that, the imperfect competition in the rail market and its operational and financial rigidities imply that pricing decisions could be unfair and produce undesired demand effects. These difficulties should not prevent, however, advancing towards the application to rail of adequate charging methods for its environmental costs. This paper addresses the problem of setting environmentally differentiated rail charges through an analytical approach. A generalised formulation is developed that sets the level of charges as a function of the degree of internalisation in other modes. Then, the optimal trade-off in the level of differentiation is assessed to extract general guidelines. Based on this, both the derived overall costs and benefits and the impacts on each agent are quantified. (Author)

A low power and low distortion rail-to-rail input/output amplifier using constant current technique

International Nuclear Information System (INIS)

Liu Yan; Zhao Yiqiang; Zhang Shilin; Zhao Hongliang

2011-01-01

A rail-to-rail amplifier with constant transconductance, intended for audio processing, is presented. The constant transconductance is obtained by a constant current technique based on the input differential pairs operating in the weak inversion region. MOSFETs working in the weak inversion region have the advantages of low power and low distortion. The proposed rail-to-rail amplifier, fabricated in a standard 0.35 μm CMOS process, occupies a core die area of 75 x 183 μm 2 . Measured results show that the maximum power consumption is 85.37 μW with a supply voltage of 3.3 V and the total harmonic distortion level is 1.2% at 2 kHz. (semiconductor integrated circuits)

We propose the use of a rail gun powered by an explosive magnetic flux compression generator built into the rail gun itself in which the rails of the gun are driven together behind the projectile by explosives. The magnetic field established between the rails by an initial current supplied by an external source at the breech of the gun is trapped and compressed by the collapsing rails to accelerate the projectile down the bore of the gun

Nationalism and Racism in the Patriotism of the Group "Here is Slovenia"

Directory of Open Access Journals (Sweden)

Veronika Bajt

2015-06-01

Full Text Available The article draws attention to the problem of self-proclaimed “patriotic” groups, which in Slovenia use patriotism to legitimize intolerant nationalist and racist as well as homophobic rhetoric and action. It is a case study of the “patriotic” groups entitled Here is Slovenia, which serves to highlight the connection between patriotism, nationalism and racism. This movement is characterized by its strong emphasis on young people, to whom Here is Slovenia speaks through a variety of programs, campaigns and socializing events. The article situates this case in discussions of nationalist and racist tendencies that enable the promotion of intolerant and hateful messages based on a primordial understanding of the nation as a homogeneous ethno-cultural community. Symbols, ideology, discourse and operation of the project Here is Slovenia are analyzed by examining the group's history and overview of its main activities, exposing the role of the Internet and social networks, in particular Facebook. The paper complements this with an analysis of interviews with (former members and supporters, whose narratives allow a rare insight into the thinking that otherwise remains outside dominant discursive practices.

Momentum equation for arc-driven rail guns

International Nuclear Information System (INIS)

Batteh, J.H.

1984-01-01

In several models of arc-driven rail guns, the rails are assumed to be infinitely high to simplify the calculation of the electromagnetic fields which appear in the momentum equation for the arc. This assumption leads to overestimates of the arc pressures and accelerations by approximately a factor of 2 for typical rail-gun geometries. In this paper, we develop a simple method for modifying the momentum equation to account for the effect of finite-height rails on the performance of the rail gun and the properties of the arc. The modification is based on an integration of the Lorentz force across the arc cross section at each axial location in the arc. Application of this technique suggests that, for typical rail-gun geometries and moderately long arcs, the momentum equation appropriate for infinite-height rails can be retained provided that the magnetic pressure term in the equation is scaled by a factor which depends on the effective inductance of the gun. The analysis also indicates that the magnetic pressure gradient actually changes sign near the arc/projectile boundary because of the magnetic fields associated with the arc current

Electron emission at the rail surface

International Nuclear Information System (INIS)

Thornhill, L.; Battech, J.

1991-01-01

In this paper the authors examine the processes by which current is transferred from the cathode rail to the plasma armature in an arc-driven railgun. Three electron emission mechanisms are considered, namely thermionic emission, field-enhanced thermionic emission (or Schottky emission), and photoemission. The author's calculations show that the dominant electron emission mechanism depends, to a great extent, on the work function of the rail surface, the rail surface temperature, the electric field at the rail surface, and the effective radiation temperature of the plasma. For conditions that are considered to be typical of a railgun armature, Schottky emission is the dominant electron emission mechanism, providing current densities on the order of 10 9 A/m 2

Blewett, Verna; Rainbird, Sophia; Dorrian, Jill; Paterson, Jessica; Cattani, Marcus

2012-01-01

'Safety culture' is identified in the literature as a critical element of healthy and safe workplaces. How can rail organizations ensure that consistently effective work health and safety cultures are maintained across the diversity of their operations? This paper reports on research that is currently underway in the Australian rail industry aimed at producing a Model of Best Practice in Safety Culture for the industry. Located in rail organizations dedicated to the mining industry as well as urban rail and national freight operations, the research examines the constructs of organizational culture that impact on the development and maintenance of healthy and safe workplaces. The research uses a multi-method approach incorporating quantitative (survey) and qualitative (focus groups, interviews and document analysis) methods along with a participative process to identify interventions to improve the organization and develop plans for their implementation. The research uses as its analytical framework the 10 Platinum Rules, from the findings of earlier research in the New South Wales (Australia) mining industry, Digging Deeper. Data collection is underway at the time of writing and preliminary findings are presented at this stage. The research method may be adapted for use as a form of organizational review of safety and health in organizational culture.

Les compositions mémorielles autour de la Guerre patriotique. L’exemple du souvenir de Moussa Djalil, Tatar, stalinien, poète et patriote Memory Schemes Around the Patriotic War. The Example of the Memory of Musa Dzhalil, Tatar, Stalinist, Poet and Patriot

Directory of Open Access Journals (Sweden)

2012-01-01

Full Text Available This article proposes to study the memorial destiny of Musa Dzhalil, a Tatar poet well-known in Russia for his Moabit Notebook written in the Berlin prison where he died in 1944. After 1956, he became posthumously an official Hero of the Soviet Union and won the Lenin Prize for his work. His popularity survived the disappearance of the USSR and Musa Dzhalil is still a popular figure in Russia today. This popularity is the result of a complex combination of factors : he is celebrated as a great patriot (for his military exploit in Germany but also as a representative of the Tatar culture (he wrote his work in Tatar, as an artist (his poems were translated into Russian and, last but not least, as a representative of the Soviet society (of the Stalinist period. Because of the mixing of these different components, the cult of Musa Dzhalil can be appropriated simultaneously by different groups in Post-Soviet society (Russian leadership, Tatar authorities, Communist Party, Cultural institutions. This complex combination of supports forbids any critical assessment of Dzhalil’s memory. Critics against him are immediately denounced as anti-Tatar, anti-Soviet, anti-cultural and anti-Russian. This paper thus shows, through the example of Musa Dzhalil, the insertion of Great Patriotic War memory in a complex collection of social and political bonds.

Ronggang Cao

2017-01-01

Full Text Available Rail-gun should not only be used to military applications, but also can be developed as applications in the civilian aspects of the market. With the development of the electromagnetic launch technology, based on the similarity theory, using the existing rail-gun model to guide the construction of more economical miniature calibre rail-guns, and apply it in some machinery and equipment, this idea will open up a wider rail-gun application space. This article will focus on the feasibility of application of miniature calibre rail-guns in the mechanical arm. This paper designs the schematic diagram, then theoretical analyzes force conditions of the armature in the mechanical arm, calculates the possible range of the current amplitude and so on. The existing rail-gun model can be used to guides design the circuit diagram of the miniature calibre rail-gun. Based on the similarity theory and many simulation experiments, designed the experimental parameters of a miniature rail-gun and analyzed the current, Lorentz force, velocity, and location of the existing rail-gun and miniature rail-gun. The results show that the rail-gun launching technology applied to robot arms is feasibility. The application of miniature calibre rail-guns in the mechanical arm will benefit to the further development of rail-guns.

FlexCargoRail is a concept for self propelled electric freight wagons. This will enhance rail operations on first and last mile. The concept can be integrated in the existing rail system, so migration is possible without any lost investments. Standard components from industry and rail are used to realise the FCR wagon. Motors, transmissions, control and batteries are available and approved. One of the effects is to enhance service for loading terminals. This can become independent from factory siding operation. From the economic point of view, FCR is realisable. This is shown by target costing. Efficiency of FCR is dependent from high frequent use of FCR rail cars and the use of the possibility to shunt also conventional freight wagons with FCR wagons. Migration should be carried out in logistical networks with frequent operations between plants and sidings with a closed wagon pool. (orig.)

A Rails / Django Comparison

Directory of Open Access Journals (Sweden)

2008-06-01

Full Text Available Ruby on Rails (“Rails” is the dominant web programming framework for Ruby and, even outside the Ruby community, is considered the epitome of the latest generation of high-productivity, open source web development tools. Django is one of many competing web development frameworks for Python. It is notable, first, for being highly regarded amongst Python programmers, and second, for being one of the few of the new generation of framework that does not ape Ruby on Rails. Both Rails and Django claim greatly enhanced productivity, compared with more traditional web development frameworks. In this paper, we compare the two frameworks from the point of view of a developer attempting to choose one of the two frameworks for a new project.

Future Parking Demand at Rail Stations in Klang Valley

Directory of Open Access Journals (Sweden)

Ho Phooi Wai

2017-01-01

Full Text Available Klang Valley, Malaysia is currently undergoing a massive development of rail transportation system expansion where the current integrated rail transit system will see new extensions of two MRT lines and an LRT line by year 2020. By year 2017, the first MRT line will be ready to run with 31 new rail stations connected to the current passenger rail network. The existing Park and Ride facilities in Klang Valley are commonly known as being unable to sufficiently cater for the current parking space demand. Therefore, with the expansion of many additional rail stations which are rapidly under construction, there are doubts that the future parking space at rail stations will be able to accommodate the sudden rise of rail passengers. Although the authorities are increasing parking bays at various locations, will the future parking demand at rail stations be sufficient? This paper studies the factors influencing parking demand in terms of population, car ownership, new car registrations and passenger rail ridership and estimating the future parking demand using Linear Regression method. Result shows that the forecasted parking demand at rail stations after the implementation of the first new MRT system in 2017 is 2.7 times more than in 2014.

Characterization of deformed pearlitic rail steel

Science.gov (United States)

Nikas, Dimitrios; Meyer, Knut Andreas; Ahlström, Johan

2017-07-01

Pearlitic steels are commonly used for railway rails because they combine good strength and wear properties. During service, the passage of trains results in a large accumulation of shear strains in the surface layer of the rail, leading to crack initiation. Knowledge of the material properties in this region is therefore important for fatigue life prediction. As the strain is limited to a thin surface layer, very large strain gradients can be found. This makes it very difficult to quantify changes in material behavior. In this study hardness measurements were performed close to the surface using the Knoop hardness test method. The orientation of the pearlitic lamellas was measured to give an overview of the deformed microstructure in the surface of the rail. Microstructural characterization of the material was done by optical microscopy and scanning electron microscopy to evaluate the changes in the microstructure due to the large deformation. A strong gradient can be observed in the top 50 μm of the rail, while deeper into the rail the microstructure of the base material is preserved.

Králíček J.

2007-11-01

Full Text Available The article deals with the vibroacoustical analysis of rail vehicle and is the extension of the previously presented work “Modelování podvozku kolejového vozidla s poddajným rámem”. The vibroacoustical analysis uses the outcomes of the dynamical analysis of rail vehicle bogie i.e. surface velocities of the bogie frame to compute the acoustic power radiated by the bogie frame and forces acting in the bogie-body interface. The radiated power and the force spectra are then used as the excitation to the rail body model in the environment Auto-SEA to compute the interior acoustic quantities.

The rail abandonment process: A southern perspective

International Nuclear Information System (INIS)

1988-12-01

One factor in evaluating the desirability of rail transport for high-level radioactive wastes or spent fuels is the frequency, or lack thereof, with which railroad and railroad lines have been, and are, abandoned. If DOE makes a decision to use the rail option and a line is subsequently abandoned, the choice results in increased cost, time delays and possibly safety problems: Information is therefore needed prior to the decision-making process to evaluate the desirability of the rail shipping option. One result of the abandonments mentioned herein, as well as other later abandonments, is the creation of a US rail system undergoing an evolutionary process in the 1980s as far-reaching as the changes that occurred when the industry was in its infancy a century and-a-half ago. The purpose of this paper is to examine the factors leading to some of these changes by tracing the historical development of the rail abandonment process, with particular emphasis on the rise of regional railroads, their problems in the modern era and current trends in rail abandonments as well as their effects on the southeastern United States

Can urban rail transit curb automobile energy consumption?

International Nuclear Information System (INIS)

Lin, Boqiang; Du, Zhili

2017-01-01

With the rapid development of China's economy and the speed of urbanization, China's automobile sector has experienced rapid development. The rapid development of the automobile sector has increased energy consumption. According to the results of this paper, automobile energy consumption accounted for about 10.73% of total energy consumption in China in 2015, about 3.6 times the proportion a decade ago. With the deterioration of urban traffic conditions, relying on expanding the amount of vehicles and city road network cannot solve the problem. Urban rail transit is energy-saving and less-polluting, uses less space, has large capacity, and secure. Urban rail transit, according to the principle of sustainable development, is a green transportation system and should be especially adopted for large and medium-sized cities. The paper uses the binary choice model (Probit and Logit) to analyze the main factors influencing the development of rail transit in Chinese cities, and whether automobile energy consumption is the reason for the construction of urban rail transit. Secondly, we analyze the influence of urban rail transit on automobile energy consumption using DID model. The results indicate that the construction of urban rail traffic can restrain automobile energy consumption significantly, with continuous impact in the second year. - Highlights: • Investigate the main factors influencing the building of rail transit for Chinese cities. • Analyze the influence of urban rail transit on automobile energy consumption by DID model. • The results indicate that the construction of urban rail traffic can restrain automobile energy consumption significantly.

Two-Dimensional Impact Reconstruction Method for Rail Defect Inspection

Directory of Open Access Journals (Sweden)

Jie Zhao

2014-01-01

Full Text Available The safety of train operating is seriously menaced by the rail defects, so it is of great significance to inspect rail defects dynamically while the train is operating. This paper presents a two-dimensional impact reconstruction method to realize the on-line inspection of rail defects. The proposed method utilizes preprocessing technology to convert time domain vertical vibration signals acquired by wireless sensor network to space signals. The modern time-frequency analysis method is improved to reconstruct the obtained multisensor information. Then, the image fusion processing technology based on spectrum threshold processing and node color labeling is proposed to reduce the noise, and blank the periodic impact signal caused by rail joints and locomotive running gear. This method can convert the aperiodic impact signals caused by rail defects to partial periodic impact signals, and locate the rail defects. An application indicates that the two-dimensional impact reconstruction method could display the impact caused by rail defects obviously, and is an effective on-line rail defects inspection method.

The Rail Alignment Environmental Impact Statement: An Update

International Nuclear Information System (INIS)

Sweeney, R.

2005-01-01

On July 23,2002, the President of the United States signed into law a joint resolution of the United States Congress designating the Yucca Mountain site in Nye County, Nevada, for development as a geologic repository for the disposal of spent nuclear fuel and high-level radioactive waste. If the US. Nuclear Regulatory Commission authorizes construction of the repository and receipt and possession of spent nuclear fuel and high-level radioactive at Yucca Mountain, the U.S. Department of Energy (DOE) would be responsible for transporting these materials to the Yucca Mountain repository as part of its obligation under the Nuclear Waste Policy Act. Part of the site recommendation decision included the analysis of a nation-wide shipping campaign to the proposed repository site. The ''Final Environmental Impact Statement for a Geologic Repository for the Disposal of Spent Nuclear Fuel and High-Level Radioactive Waste at Yucca Mountain, Nye County, Nevada'' (February 2002) (Repository EIS) evaluated the potential impacts of the transportation of 70,000 Metric Tons of Heavy Metal spent nuclear fuel and high-level radioactive waste from 77 locations around the nation to the potential repository in Nevada over a 24 year shipping campaign. In the Repository EIS, DOE identified mostly rail as its preferred mode of transportation, both nationally and in the State of Nevada. In December 2003, based on public comments and the environmental analyses in the Repository EIS, DOE identified a preference for the Caliente rail corridor in Nevada. On April 8, 2004, DOE issued a Record of Decision (ROD) on the Mode of Transportation and Nevada Rail Corridor for the Disposal of Spent Nuclear Fuel and High-Level Radioactive Waste at Yucca Mountain, Nye County, Nevada. In this ROD, the DOE announced that it had decided to select the mostly rail scenario analyzed in the Repository EIS as the transportation mode both on a national basis and in the State of Nevada.

1991-01-01

A comparative study of electromagnetic acceleration in the rail-type accelerators with two kinds of rail geometry was carried out experimentally. The accelerators were energized by 200kJ capacitor bank and the weight of loaded projectiles was about 1.3 grams with 10mm x 10mm square bore. The attained velocity was 4.3km/s in the augmented accelerator, while it was 3.8km/s in the classical device. In this paper these differences in attained velocity are briefly discussed.

Hard-driven rail-gun tests

Peterson, D.R.; Adams, D.F.; Cummings, C.E.; Fowler, C.M.; Kerrisk, J.F.; Marsh, S.P.; Parker, J.V.

1983-01-01

A number of prototype rail-gun designs have been tested, powered by explosive magnetic flux compression generators. Peak currents as high as 1.3 MA were delivered. Rail guns with 50-mm-thick Kevlar fiberwound structural shells were able to survive these high currents with minimum mechanical damage and were refired after enlarging the bores 0.2 to 0.4 mm to remove arc damage. In some tests, mechanical damage occurred that was apparently caused by the rebound of the gun after firing. Although the Kevlar shells had more than adequate strength, they appeared to lack sufficient stiffness, allowing excessive deflections. The use of a steel structural shell with a Kevlar sleeve was an improvement. Intrusion into the seams of the rail guns and condensation of material from the plasma armature were observed. Improved sealing of seams is indicated. In some cases, we suspect maldistribution of current within the gun; that is, not all the current delivered to the breech of the gun seemed to reach the plasma armature. Experiments are being designed to quantify the effects discussed. Rail guns of advanced design are being fabricated. An 18-g titanium projectile was accelerated to 2.4 km/s in a 16-mm-round-bore, 0.6-m-long gun, 4-6 g polycarbonate projectiles were accelerated to 3.5 km/s in 13-mm-square-bore, 1.2-m-long rail guns. All tests were conducted at atmospheric pressure

Detection method based on Kalman filter for high speed rail defect AE signal on wheel-rail rolling rig

Science.gov (United States)

Hao, Qiushi; Shen, Yi; Wang, Yan; Zhang, Xin

2018-01-01

Nondestructive test (NDT) of rails has been carried out intermittently in traditional approaches, which highly restricts the detection efficiency under rapid development of high speed railway nowadays. It is necessary to put forward a dynamic rail defect detection method for rail health monitoring. Acoustic emission (AE) as a practical real-time detection technology takes advantage of dynamic AE signal emitted from plastic deformation of material. Detection capacities of AE on rail defects have been verified due to its sensitivity and dynamic merits. Whereas the application under normal train service circumstance has been impeded by synchronous background noises, which are directly linked to the wheel speed. In this paper, surveys on a wheel-rail rolling rig are performed to investigate defect AE signals with varying speed. A dynamic denoising method based on Kalman filter is proposed and its detection effectiveness and flexibility are demonstrated by theory and computational results. Moreover, after comparative analysis of modelling precision at different speeds, it is predicted that the method is also applicable for high speed condition beyond experiments.

The Homogeneity Research of Urban Rail Transit Network Performance

Directory of Open Access Journals (Sweden)

Wang Fu-jian

2016-01-01

Full Text Available Urban Rail Transit is an important part of the public transit, it is necessary to carry out the corresponding network function analysis. Previous studies mainly about network performance analysis of a single city rail transit, lacking of horizontal comparison between the multi-city, it is difficult to find inner unity of different Urban Rail Transit network functions. Taking into account the Urban Rail Transit network is a typical complex networks, so this paper proposes the application of complex network theory to research the homogeneity of Urban Rail Transit network performance. This paper selects rail networks of Beijing, Shanghai, Guangzhou as calculation case, gave them a complex network mapping through the L, P Space method and had a static topological analysis using complex network theory, Network characteristics in three cities were calculated and analyzed form node degree distribution and node connection preference. Finally, this paper studied the network efficiency changes of Urban Rail Transit system under different attack mode. The results showed that, although rail transport network size, model construction and construction planning of the three cities are different, but their network performance in many aspects showed high homogeneity.

Ceramic Rail-Race Ball Bearings

Science.gov (United States)

Balzer, Mark A.; Mungas, Greg S.; Peters, Gregory H.

2010-01-01

Non-lubricated ball bearings featuring rail races have been proposed for use in mechanisms that are required to function in the presence of mineral dust particles in very low-pressure, dry environments with extended life. Like a conventional ball bearing, the proposed bearing would include an inner and an outer ring separated by balls in rolling contact with the races. However, unlike a conventional ball bearing, the balls would not roll in semi-circular or gothic arch race grooves in the rings: instead, the races would be shaped to form two or more rails (see figure). During operation, the motion of the balls would push dust particles into the spaces between the rails where the particles could not generate rolling resistance for the balls

Assessment of rail long-pitch corrugation

Science.gov (United States)

Valehrach, Jan; Guziur, Petr; Riha, Tomas; Plasek, Otto

2017-09-01

The paper focuses on defects of the running surface of the rail, namely the rail corrugation defect and specifically long-pitch corrugation in curves of small radii. These defects cause a shorter life of the rails, greater maintenance costs and increase the noise and vibration pollution. Therefore, it is very important to understand the formation and development of the imperfection of the rails. In the paper, various sections of railway tracks in the Czech Republic are listed, each of them completed with comparison of defect development, the particular track superstructure, rolling stock, axle load, traffic load etc. Based on performed measurements, defect development has been proved as different on sections with similar (or even same) parameters. The paper assumes that a train velocity is the significant circumstance for defect development rates. Assessment of track section with under sleeper pads, which are expected to be the one of the possible ways to suppress the corrugation defect development, is included in evaluation.

Rail Vehicle Vibrations Control Using Parameters Adaptive PID Controller

Directory of Open Access Journals (Sweden)

Muzaffer Metin

2014-01-01

Full Text Available In this study, vertical rail vehicle vibrations are controlled by the use of conventional PID and parameters which are adaptive to PID controllers. A parameters adaptive PID controller is designed to improve the passenger comfort by intuitional usage of this method that renews the parameters online and sensitively under variable track inputs. Sinusoidal vertical rail misalignment and measured real rail irregularity are considered as two different disruptive effects of the system. Active vibration control is applied to the system through the secondary suspension. The active suspension application of rail vehicle is examined by using 5-DOF quarter-rail vehicle model by using Manchester benchmark dynamic parameters. The new parameters of adaptive controller are optimized by means of genetic algorithm toolbox of MATLAB. Simulations are performed at maximum urban transportation speed (90 km/h of the rail vehicle with ±5% load changes of rail vehicle body to test the robustness of controllers. As a result, superior performance of parameters of adaptive controller is determined in time and frequency domain.

Effects of the Republic of Serbia’s citizens’ patriotism and animosity towards the European union on consumer ethnocentrism

Directory of Open Access Journals (Sweden)

Veljko Marinkovic

2017-05-01

Full Text Available Economic, political and militaristic tensions between countries are present throughout the world. The devastating effects of the global financial crisis are still generating the ever-increasing instability of the world economy. Patriotism and nationalism, as well as animosity towards the economic and military policies of certain foreign countries, seem to be on the rise across many countries and nations in recent years. It is precisely the current situation in the world that is favorable for encouraging citizens to purchase domestic products. The policy can be particularly useful for less-developed import-oriented economies. Thus, in the conditions of the economic crisis, the study of consumer ethnocentrism is gaining in importance. The paper examines the effects of the patriotism of the citizens of the Republic of Serbia and animosity towards the EU on consumer ethnocentrism. The results show that both these variables stand out as the statistically significant antecedents of consumer ethnocentrism; however, it should be noticed that patriotism shows a stronger influence on the consumer’s orientation towards buying domestic products. The research findings indicate that love of one’s country may direct consumer choices towards domestic brands, despite the positive image and high quality of foreign ones. In addition, due to citizens’ strong dislike towards the EU economic policy, some of them may decide to buy lower-quality domestic products; however, this does not necessarily negatively affect one’s perception of foreign products.

Finite element analysis of rail-wheel interaction

International Nuclear Information System (INIS)

Rahman, F.; Kharlamov, Y.A.; Islam, S.; Khan, A.A.

2006-01-01

Damage mechanisms such as surface cracks, plastic deformation and wear can significantly reduce the service life of railway track and rolling stock. They also have a negative impact on the rolling noise as well as: on the riding comfort. A proper understanding of these mechanisms requires a detailed knowledge of physical interaction between wheel and rail. Furthermore, demands for higher train speeds and increased axle loads implies that the consequences of larger contact. forces between wheel and rail must be thoroughly investigated. Two methods have traditionally been used to investigate the rail-wheel contact, that is the Hertz analytical method and simplified numerical method based on the boundary element (BE) method. These methods rely on a half-space assumption and a linear material model. This paper presents that to overcome these limitations, a tool for FE-based quasistatic wheel-rail contact simulations has been developed. The tool is a library of ANSYS macro routines for configuring, meshing and loading of a parametric wheel-rail model. The meshing is based on measured wheel and rail profiles. The wheel and rail materials in the contact region are treated as elastic-plastic with kinematic hardening. By controlling the values of the configuration parameters, representations of various driving cases can be generated. The quasi-static loads are obtained from train motion. Interaction phenomena such as rolling, spinning and sidling can be included. The modeling tool and a methodology are described in the presented paper. Significant differences in the calculated state between the FE solution and the traditional approaches can be observed. These differences are most significant in situations with flange contact.

Railway infrastructure monitoring is a vital task to ensure rail transportation safety. A rail failure could result in not only a considerable impact on train delays and maintenance costs, but also on safety of passengers. In this article, the aim is to assess the risk of a rail failure by analyzing a type of rail surface defect called squats that are detected automatically among the huge number of records from video cameras. We propose an image processing approach for automatic detection of squats, especially severe types that are prone to rail breaks. We measure the visual length of the squats and use them to model the failure risk. For the assessment of the rail failure risk, we estimate the probability of rail failure based on the growth of squats. Moreover, we perform severity and crack growth analyses to consider the impact of rail traffic loads on defects in three different growth scenarios. The failure risk estimations are provided for several samples of squats with different crack growth lengths on a busy rail track of the Dutch railway network. The results illustrate the practicality and efficiency of the proposed approach. © 2017 The Authors Risk Analysis published by Wiley Periodicals, Inc. on behalf of Society for Risk Analysis.

Structural response of a rail acceleration

International Nuclear Information System (INIS)

Wang, S.Y.

1984-01-01

The transient response of a 0.4 by 0.6 cm rectangular bore rail accelerator was analyzed by a three dimensional finite element code. The copper rail deflected to a peak value of 0.08 mm in compression and then oscillated at an amplitude of 0.02 mm. Simultaneously the insulating side wall of glass fabric base, epoxy resin laminate (G-10) was compressed to a peak value of 0.13 mm and rebounded to a steady state in extension. Projectile pinch or blowby due to the rail extension or compression, respectively, can be identified by examining the time history of the rail displacement. The effect of blowby was most significant at the side wall characterized by mm size displacement in compression. Dynamic stress calculations indicate that the G-10 supporting material behind the rail is subjected to over 21 MPa at which the G-10 could fail if the laminate was not carefully oriented. Results for a polycarbonate resin (Lexan) side wall show much larger displacements and stresses than for G-10. The tradeoff between the transparency of Lexan and the mechanical strength of G-10 for sidewall material is obvious. Displacement calculations from the modal method are smaller than the results from the direct integration method by almost an order of magnitude, because the high frequency effect is neglected. 12 references

Plasma treatment of crane rails

Directory of Open Access Journals (Sweden)

Владислав Олександрович Мазур

2016-07-01

Full Text Available Crane operation results in wear and tear of rails and crane wheels. Renovation and efficiency of these details is therefore relevant. Modern technologies of wheels and rails restoration use surfacing or high-frequency currents treatment. Surface treatment with highly concentrated streams of energy- with a laser beam, plasma jet- is a promising direction.. It is proposed to increase the efficiency of crane rails by means of surface plasma treatment. The modes of treatment have been chosen.. Modelling of plasma jet thermal impact on a solid body of complex shape has been made. Plasma hardening regimes that meet the requirements of production have been defined. Structural transformation of the material in the crane rails on plasma treatment has been investigated. It has been concluded that for carbon and low alloy crane steels the plasma exposure zone is characterized by a high degree of hardened structure dispersion and higher hardness as compared to the hardness after high-frequency quenching. As this takes place phase transformations are both shift (in the upper zone of plasma influence and fluctuation (in the lower zone of the plasma. With high-speed plasma heating granular or lamellar pearlite mainly transforms into austenite. The level of service characteristics of hardened steel, which is achieved in this case is determined by the kinetics and completeness of pearlite → austenite transformation. For carbon and low alloy rail steels plasma hardening can replace bulk hardening, hardening by high-frequency currents, or surfacing. The modes for plasma treatment which make it possible to obtain a surface layer with a certain service characteristics have been defined

Revisiting the reasons for contact fatigue defects in rails

Directory of Open Access Journals (Sweden)

Darenskiy Alexander

2017-01-01

Full Text Available As it is known rail is one of the most significant elements of the whole railway construction. Operation under alternating loads from wheels of the rolling stock and different ambient temperatures lead to appearance and development of rail defects and damages. A great variety of operational factors (freight traffic density, axial loads, traffic speeds, track layout and profile as well as special features of manufacturing and thermal treatment of rails create certain difficulties while identifying reasons for defects and damages. The article deals with an attempt to estimate influence of track layout and lateral forces on appearance of defects and damages in rails on the base of long-term observations of rail operation in Kharkiv Metro. On the basis of the vehicle/track mathematical model which considers structural features of both rolling stock and permanent way in underground systems, the level of lateral forces in curves was calculated. The coefficients of correlation between the track curvature, the level of forces and the amount of defected rails removed were later obtained, that made it possible to determine the dominant factor which may lead to appearance and development of contact fatigue defects in rails laid in curves.

Improving fatigue performance of rail thermite welds

Science.gov (United States)

Jezzini-Aouad, M.; Flahaut, P.; Hariri, S.; Winiar, L.

2010-06-01

Rail transport development offers economic and ecological interests. Nevertheless, it requires heavy investments in rolling material and infrastructure. To be competitive, this transportation means must rely on safe and reliable infrastructure, which requires optimization of all implemented techniques and structure. Rail thermite (or aluminothermic) welding is widely used within the railway industry for in-track welding during re-rail and defect replacement. The process provides numerous advantages against other welding technology commonly used. Obviously, future demands on train traffic are heavier axle loads, higher train speeds and increased traffic density. Thus, a new enhanced weld should be developed to prevent accidents due to fracture of welds and to lower maintenance costs. In order to improve such assembly process, a detailed metallurgical study coupled to a thermomechanical modelling of the phenomena involved in the thermite welding process is carried out. Obtained data enables us to develop a new improved thermite weld (type A). This joint is made by modifying the routinely specified procedure (type B) used in a railway rail by a standard gap alumino-thermic weld. Joints of type A and B are tested and compared. Based on experimental temperature measurements, a finite element analysis is used to calculate the thermal residual stresses induced. In the vicinity of the weld, the residual stress patterns depend on the thermal conditions during welding as it also shown by litterature [1, 2]. In parallel, X-Ray diffraction has been used to map the residual stress field that is generated in welded rail of types A and B. Their effect on fatigue crack growth in rail welds is studied. An experimental study based on fatigue tests of rails welded by conventional and improved processes adjudicates on the new advances and results will be shown.

Furthermore, findings in this paper show that planners, policy makers and other stakeholders shape stories for or against the implementation of light rail through the use of narratives that are linked...... infrastructure projects and urban interventions through the political process and secure the outcome of these projects are recognisable in proportion to the visionary concept....

The literature of the California black rail

Science.gov (United States)

Wilbur, Sanford R.

1974-01-01

Few birds have remained so little known as the California black rail (Laterallus jamaicensis coturniculus). Although first collected in 1859 or before and reported in 1874 (Ridgway 1874), its life history, distribution, and status have remained so obscure that even a sight record of the bird is deemed worthy of a report in some ornithological publications. Because degradation and loss of freshwater and saltwater marshlands in California may be detrimentally affecting the black rail, both the U.S. Bureau of Sport Fisheries and Wildlife (1973) and the California Department of Fish and Game (1972) have classified it as rare and worthy of further study. The 84 papers and notes both summarized in this report and included in its bibliography include essentially all that is currently known about the California black rail. Only 11 of these papers consider the life history of this rail in any detail. The rest are distribution notes and some of the more important papers on the closely related eastern black rail (L. j. jamaicensis). The latter are included for comparative purposes, or because they may lend clues to currently unknown facets of the life history of the western race.

Three-dimensional rail cooling analysis for a repetitively fired railgun

International Nuclear Information System (INIS)

Liu, H.P.

1991-01-01

This paper reports on a three-dimensional (3-D) rail cooling analysis for fabrication and demonstration of a stand-alone repetitive fire compulsator driven 9 MJ gun system which has been performed to assure the entire rail can be maintained below its thermal limit for multiple shots. The 3-D rail thermal model can predict the temperature, pressure, and convective heat transfer coefficient variations of the coolant along the 10 m long copper rail. The 9-MJ projectiles will be fired every 20 s for 3 min. Water cooling was used in the model for its high cooling capacity. Single liquid phase heat transfer was assumed in the cooling analysis. For multiple shots, the temperature difference between the rail and the water was enhanced due to accumulated heat in the rail. As a result, the heat removal by water increased from shot-to-shot. The rail temperature initially increased and finally stabilized after a number of shots

Light rail is a popular tool in urban development strategies in many European cities. One argument for choosing a rail-based solution is that it signals stability to investors and will attract development and investments in the corridor. The choice of corridor in the various light rail cities...... and redistributes urban space. Furthermore light rail is not only a physical infrastructure but also an infrastructure of power that is carefully planned and designed creating both mental and physical patterns of mobilities and immobilities. Hence it is important to underline that mobility systems, such as light...

Barriers to and enablers for European rail freight transport for integrated door-to-door logistics service. Part 2: Enablers for multimodal rail freight transport

Dewan Md Zahurul ISLAM

2014-12-01

Full Text Available The objective of this paper is to examine and identify barriers to and enablers for the European rail freight transport services as a transport chain partner along the supply chains in the changing market scenario. The changing market scenario includes, among others, requiring 'door-to-door' rather than 'terminal to terminal' and integrated service, competitive ability to attract non-rail cargo type, changes in the customer requirements (e.g. reliable service and changes in the operational requirements and practices. Using a literature review method, the paper is presented in two parts. The part 1 focuses on the identification of barriers to the European rail freight service by reviewing freight logistics services for global supply chains followed by the current performance of European rail freight transport followed by a discussion on the rail freight market liberalisation in Europe. Then rail freight transport in the Unites States (U.S. is discussed. The research notes that although the background, scope and necessity for reform measures in Europe differ from those of the U.S., some lessons can be learned and the main lesson is that an appropriate reform measure can enhance rail sector competitive ability in Europe. The part 2 of the paper is dedicated to recommend some concrete steps and actions as enablers to remove the barriers identified in the part 1 to develop multimodal rail freight transport. The enablers for multimodal rail freight transport include: •\tEuropean rail freight transport market needs full liberalisation so that incumbent and new entrants can compete freely. •\tThe rail operators need to acquire service (e.g. customer tailored services, door to door service quality offered by road freight operators. •\tThey need to conduct a combination of ‘terminal-to-terminal’ and door-to-door operations, as and when needed; •\tThey must build partnership with freight forwarder or 3PLs to include all types of customers

Full Text Available The promoting of a patriotic cinema by the Russian state favored a new production, which appropriates in various ways this topos of the Soviet cinéma which is the patriotic Great War. The variety of the films is actually coupled with a big heterogeneousness of the reactions of the public; therefore the analysis of the comments of the Internet users allows to identify several fractures as for the representation of the war and for the expectations of the spectators. This study illustrates the lack of consensus around the war, it allows to seize the modulations and inflections of the patriotic theme and to understand the indignation, that met Mikhalkov's film Burnt by the Sun 2.

Rail for inspection/maintenance device in TOKAMAK type container of a thermonuclear reactor

International Nuclear Information System (INIS)

Takahashi, Kenji.

1996-01-01

A circular rail divided into four arcuate parts for an inspection/maintenance device which runs in a TOKAMAK type container is disposed. Each of the divided rails is supported at the center of the outer surface rotatably by extendable rail supporting shafts. Each of the divided rail is constituted such that it can be contained between limiters disposed at the outer side of the TOKAMAK container when each of the rail support shafts is contracted. With such a constitution, each of the rail support shafts and arcuate rail is contracted and rotated from the outside of the TOKAMAK type container by an actuator. In order to form a circular rail, each of the rail support shafts is extended toward the center of the TOKAMAK type container, and then each of the arcuate rails is rotated into a horizontal state. Then, the joint portions of each of the arcuate rails are connected by using remote controllable locking rods. (I.S.)

Field homogeneity improvement of maglev NdFeB magnetic rails from joints.

An ideal magnetic rail should provide a homogeneous magnetic field along the longitudinal direction to guarantee the reliable friction-free operation of high temperature superconducting (HTS) maglev vehicles. But in reality, magnetic field inhomogeneity may occur due to lots of reasons; the joint gap is the most direct one. Joint gaps inevitably exist between adjacent segments and influence the longitudinal magnetic field homogeneity above the rail since any magnetic rails are consisting of many permanent magnet segments. To improve the running performance of maglev systems, two new rail joints are proposed based on the normal rail joint, which are named as mitered rail joint and overlapped rail joint. It is found that the overlapped rail joint has a better effect to provide a competitive homogeneous magnetic field. And the further structure optimization has been done to ensure maglev vehicle operation as stable as possible when passing through those joint gaps. The results show that the overlapped rail joint with optimal parameters can significantly reduce the magnetic field inhomogeneity comparing with the other two rail joints. In addition, an appropriate gap was suggested when balancing the thermal expansion of magnets and homogenous magnetic field, which is considered valuable references for the future design of the magnetic rails.

Do Urban Rail Transit Facilities Affect Housing Prices? Evidence from China

Directory of Open Access Journals (Sweden)

Xu Zhang

2016-04-01

Full Text Available Urban rail transit facilities play a critical role in citizen’s social activities (e.g., residence, work and education. Using panel data on housing prices and urban rail transit facilities for 35 Chinese cities for 2002 to 2013, this study constructs a panel data model to evaluate the effect of rail transit facilities on housing prices quantitatively. A correlation test reveals significant correlations between housing prices and rail transit facilities. Empirical results demonstrate that rail transit facilities can markedly elevate real estate prices. Quantitatively, a 1% increase in rail transit mileage improves housing prices by 0.0233%. The results highlight the importance of other factors (e.g., per capita GDP, land price, investment in real estate and population density in determining housing prices. We also assess the effects of expectations of new rail transit lines on housing prices, and the results show that expectation effects are insignificant. These findings encourage Chinese policy makers to take rail transit facilities into account in achieving sustainable development of real estate markets.

A novel permanent magnetic rail for HTS levitation propulsion system

International Nuclear Information System (INIS)

Guo, F.; Tang, Y.; Ren, L.; Li, J.

2009-01-01

The Halbach Array has a characteristic advantage that the spatial fundamental field is canceled on one side of the array while the field intensity on the other side is enhanced. So this array could be used in the design of high temperature superconducting permanent magnetic levitation rail to improve the surface magnetic field and levitation force. This paper compared the surface magnetic field of the Halbach Array rail and two conventional levitation rails at first. Then proposed the potential advantages of Halbach Array applied in permanent magnetic rail system. But the Halbach Array rail is mechanical instability. An novel improved Halbach Array rail is proposed in this paper. The new structure combined the advantages of traditional structure and Halbach Array structure, solved the problem of mechanical instability, and carried on the advantage of Halbach Array on the magnetic field distribution at the same time.

Field monitoring of rail squats using 3D ultrasonic mapping technique

International Nuclear Information System (INIS)

Kaewunruen, S.; Ishida, M.

2014-01-01

Rail squats and studs are typically classified as the propagation of any cracks .that have grown longitudinally through the subsurface. Some of the cracks could propagate to the bottom of rails transversely, which have branched from the initial longitudinal cracks with a depression of rail surface. The rail defects are commonly referred to as 'squats' when they were initiated from a damage layer caused by rolling contact fatigue, and as 'studs' when they were associated with a white etching layer caused by the transformation from pearlitic steel due to friction heat generated by wheel sliding or excessive traction. Such above-mentioned rail defects have been often observed in railway tracks catered for either light passenger or heavy freight traffics and for low, medium or high speed trains all over the world for over 60 years except some places such as sharp curves where large wear takes place under severe friction between the wheel flange and rail gauge face. It becomes a much-more significant issue when the crack grows and sometimes flakes off the rail (by itself or by insufficient rail grinding), resulting in a rail surface irregularity. Such rail surface defects induce wheel/rail impact and large amplitude vibration of track structure and poor ride quality. In Australia, Europe, and Japan, rail squats/studs have occasionally turned into broken rails. The root cause and preventive solution to this defect are still under investigation from the fracture mechanics and material sciences point of view. Some patterns of squat/stud development related to both curve and tangent track geometries have been observed and squat growth has been monitored for individual squats using ultrasonic mapping techniques. This paper highlights the field monitoring of squat/stud distribution and its growth. Squat/stud growth has been detected and scanned using the ultrasonic measurement device on a grid applied to the rail surface. The depths of crack paths at each grid node form a

Simulations of roughness initiation and growth on railway rails

Science.gov (United States)

Sheng, X.; Thompson, D. J.; Jones, C. J. C.; Xie, G.; Iwnicki, S. D.; Allen, P.; Hsu, S. S.

2006-06-01

A model for the prediction of the initiation and growth of roughness on the rail is presented. The vertical interaction between a train and the track is calculated as a time history for single or multiple wheels moving on periodically supported rails, using a wavenumber-based approach. This vertical dynamic wheel/rail force arises from the varying stiffness due to discrete supports (i.e. parametric excitation) and the roughness excitation on the railhead. The tangential contact problem between the wheel and rail is modelled using an unsteady two-dimensional approach and also using the three-dimensional contact model, FASTSIM. This enables the slip and stick regions in the contact patch to be identified from the input geometry and creepage between the wheel and rail. The long-term wear growth is then predicted by applying repeated passages of the vehicle wheelsets, as part of an iterative solution.

When an LLC-type parallel resonant converter (LLC-PRC) operates above resonant frequency, the switching transistors can be turned off at zero voltage. Further study reveals that the LLC-PRC possesses the advantage of lower converter voltage gain as compared with the conventional PRC. Based on analytic results, a complete set of design curves is obtained, from which a systematic design procedure is developed. Experimental results from a 150 W 150 kHz multioutput LLC-type PRC power supply are presented.

A systems approach to reduce urban rail energy consumption

International Nuclear Information System (INIS)

González-Gil, A.; Palacin, R.; Batty, P.; Powell, J.P.

2014-01-01

Highlights: • An insightful overview of energy usage in urban rail systems is given. • The principal measures to reduce urban rail energy consumption are appraised. • A methodology is proposed to help implement energy saving schemes in urban rail. • Regenerative braking is shown to offer the greatest energy saving potential. - Abstract: There is increasing interest in the potential of urban rail to reduce the impact of metropolitan transportation due to its high capacity, reliability and absence of local emissions. However, in a context characterised by increasing capacity demands and rising energy costs, and where other transport modes are considerably improving their environmental performance, urban rail must minimise its energy use without affecting its service quality. Urban rail energy consumption is defined by a wide range of interdependent factors; therefore, a system wide perspective is required, rather than focusing on energy savings at subsystem level. This paper contributes to the current literature by proposing an holistic approach to reduce the overall energy consumption of urban rail. Firstly, a general description of this transport mode is given, which includes an assessment of its typical energy breakdown. Secondly, a comprehensive appraisal of the main practices, strategies and technologies currently available to minimise its energy use is provided. These comprise: regenerative braking, energy-efficient driving, traction losses reduction, comfort functions optimisation, energy metering, smart power management and renewable energy micro-generation. Finally, a clear, logical methodology is described to optimally define and implement energy saving schemes in urban rail systems. This includes general guidelines for a qualitative assessment and comparison of measures alongside a discussion on the principal interdependences between them. As a hypothetical example of application, the paper concludes that the energy consumption in existing urban

Singular point analysis during rail deployment into vacuum vessel for ITER blanket maintenance

International Nuclear Information System (INIS)

Kakudate, Satoshi; Shibanuma, Kiyoshi

2007-05-01

Remote maintenance of the ITER blanket composed of about 400 modules in the vessel is required by a maintenance robot due to high gamma radiation of ∼500Gy/h in the vessel. A concept of rail-mounted vehicle manipulator system has been developed to apply to the maintenance of the ITER blanket. The most critical issue of the vehicle manipulator system is the feasibility of the deployment of the articulated rail composed of eight rail links into the donut-shaped vessel without any driving mechanism in the rail. To solve this issue, a new driving mechanism and procedure for the rail deployment has been proposed, taking account of a repeated operation of the multi-rail links deployed in the same kinematical manner. The new driving mechanism, which is deferent from those of a usual 'articulated arm' equipped with actuator in the every joint for movement, is composed of three mechanisms. To assess the feasibility of the kinematics of the articulated rail for rail deployment, a kinematical model composed of three rail links related to a cycle of the repeated operation for rail deployment was considered. The determinant det J' of the Jacobian matrix J' was solved so as to estimate the existence of a singular point of the transformation during rail deployment. As a result, it is found that there is a singular point due to det J'=0. To avoid the singular point of the rail links, a new location of the second driving mechanism and the related rail deployment procedure are proposed. As a result of the rail deployment test based on the new proposal using a full-scale vehicle manipulator system, the respective rail links have been successfully deployed within 6 h less than the target of 8 h in the same manner of the repeated operation under a synchronized cooperation among the three driving mechanisms. It is therefore concluded that the feasibility of the rail deployment of the articulated rail composed of simple structures without any driving mechanism has been demonstrated

EVALUATION OF STRAIN-STRESS STATE OF THE RAILS IN THE PRODUCTION

Directory of Open Access Journals (Sweden)

V. V. Muravev

2017-01-01

Full Text Available High values of residual stresses is one of the most common reason of breaking lots of metal constructions, including rails. These stresses can reach values of flow limit, especially in the area of faults. Estimation of residual stresses values allows to get information about technical condition of the rail and also allow to avoid abnormal situations So, the aim of the research is creating the model of stress-strain state of the rail, which was hardened in its top and bottom, and to compare modeling results with experimental measurements of stresses and discrepancy of the housing.For creating the model and making evaluations by finite element method we used a program COMSOL. Forces on the top and bottom of the rail cause tension stresses, forces on the web of the rail cause tensile stresses. We compared calculated values of stresses with discrepancy of the housing. The discrepancy of the housing is informative characteristic for estimating the residual stresses according to standards. For experimental measurements we used an acoustic structuroscope SEMA. This structuroscope uses the acoustoelastic phenomenon for measurements. We made measurements of the five rails.According to the calculation results of the model, critical discrepancy of the housing in 2 mm corresponded to the following values of maximum stresses: –54 MPa in the top of the rail, 86 MPa in the web and –62 MPa in the bottom of the rail. Experimental measurements are the following: from –48 MPa to – 64 MPa in the top of the rail, 54 MPa to 93 MPa in the web of the rail, and –59 MPA to –74 MPa in the bottom of the rail. Absolute error was ±5 MPa.Thus we created the model, which allowed to analyze strain-stress state and compare real values of stresses with discrepancy of the housing. Results of the modeling showed coincidence with structure of distribution of residual stresses in five probes of rails.

The issue of operative data reception on location and movement of railcars is significant the constantly growing requirements of the provision of timely and safe transportation. The technical solution for efficiency improvement of data collection on rail rolling stock is the implementation of an identification system. Nowadays, there are several such systems, distinguished in working principle. In the authors' opinion, the most promising for rail transportation is the RFID technology, proposing the equipping of the railway tracks by the stationary points of data reading (RFID readers) from the onboard sensors on the railcars. However, regardless of a specific type and manufacturer of these systems, their implementation is affiliated with the significant financing costs for large, industrial, rail transport systems, owning the extensive network of special railway tracks with a large number of stations and loading areas. To reduce the investment costs for creation, the identification system of rolling stock on the special railway tracks of industrial enterprises has developed the method based on the idea of priority installation of the RFID readers on railway hauls, where rail traffic volumes are uneven in structure and power, parameters of which is difficult or impossible to predict on the basis of existing data in an information system. To select the optimal locations of RFID readers, the mathematical model of the staged installation of such readers has developed depending on the non-uniformity value of rail traffic volumes, passing through the specific railway hauls. As a result of that approach, installation of the numerous RFID readers at all station tracks and loading areas of industrial railway stations might be not necessary,which reduces the total cost of the rolling stock identification and the implementation of the method for optimal management of transportation process.

2010-01-01

Maglev rail is an important part of the magnetic levitation launch system. Reducing the manufacturing cost of magnetic levitation rail is the key problem for the development of magnetic levitation launch system. The Halbach permanent array has an advantage that the fundamental spatial field is cancelled on one side of the array while the field on the other side is enhanced. So this array used in the design of high temperature superconducting permanent maglev rail could improve the surface magnetic field and the levitation force. In order to make the best use of Nd-Fe-B (NdFeB) material and reduce the cost of maglev rail, the effect of the rail's structural parameters on levitation force and the utilization rate of NdFeB material are analyzed. The optimal ranges of these structural parameters are obtained. The mutual impact of these parameters is also discussed. The optimization method of these structure parameters is proposed at the end of this paper.

1973-01-01

NASTRAN was used to study problems associated with the installation of a linear induction motor reaction rail test track. Specific problems studied include determination of the critical axial compressive buckling stress and establishment of the lateral stiffness of the reaction rail under combined loads. NASTRAN results were compared with experimentally obtained values and satisfactory agreement was obtained. The reaction rail was found to buckle at an axial compressive stress of 11,400 pounds per square inch. The results of this investigation were used to select procedures for installation of the reaction rail.

Rail Track Detection and Modelling in Mobile Laser Scanner Data

Directory of Open Access Journals (Sweden)

S. Oude Elberink

2013-10-01

Full Text Available We present a method for detecting and modelling rails in mobile laser scanner data. The detection is based on the properties of the rail tracks and contact wires such as relative height, linearity and relative position with respect to other objects. Points classified as rail track are used in a 3D modelling algorithm. The modelling is done by first fitting a parametric model of a rail piece to the points along each track, and estimating the position and orientation parameters of each piece model. For each position and orientation parameter a smooth low-order Fourier curve is interpolated. Using all interpolated parameters a mesh model of the rail is reconstructed. The method is explained using two areas from a dataset acquired by a LYNX mobile mapping system in a mountainous area. Residuals between railway laser points and 3D models are in the range of 2 cm. It is concluded that a curve fitting algorithm is essential to reliably and accurately model the rail tracks by using the knowledge that railways are following a continuous and smooth path.

Rail freight transportation concerns of developing economies: A Namibian perspective

Directory of Open Access Journals (Sweden)

Fanny Saruchera

2017-05-01

Full Text Available Background: Although rail transport appears to be well established and outperforming other transport modes in Europe and beyond, in the majority of developing economies it was observed that firms and travellers were, on the contrary, shunning from the rail. Despite considerable infrastructural investments in the African rail systems, the sector has been deteriorating over the years. Objectives: This study identifies the freight rail transportation problems faced by African developing economies, focusing on Namibia, and examines the potential actions and factors for minimising such problems, drawing lessons from some of the developed world’s success stories. Method: The objectives of this study are achieved through a survey of Windhoek-based industrial and logistics firms operating in Namibia. Self-administered survey questionnaires were distributed through the aid of trained research assistants. Results: The study’s results show that some of the reasons of shunning rail transport are a matter of attitude, whereas some are related to operational challenges. The study confirms that the transport mode used and ownership of the freight transport services used can affect the degree of satisfaction for the transportation of goods in Namibia. Conclusion: Namibian industrial and logistics firms avoid using rail, owing to its low level of satisfaction obtained from its use. Besides engaging in Public Private Partnerships (PPPs in rail transport operations, the study contends that rail transport should receive attention similar to that given to other transport modes for African economies such as Namibia to overcome the costs associated with the increasing road congestion.

Railway has emerged as a fast, convenient, safe, clean, and low-cost alternative to air and road transportation. Many countries have invested in rail transportation. In America, Europe and Asia, large investments are planned for rail transportation. This is because congestion problems can be reduced with the introduction of rail transportation. Rail transportation involves several components which are important to ensure the smooth and safe delivery of services such as locomotives, rail stations and railway tracks. Rail transit stations are places where trains stop to pick-up and drop-off passengers. Stations are vital for many to enable them to engage in work and social commitments. This paper focuses only on the rail transit station as it is one of the important components in rail transportation. It is also considered as a key public meeting place and space for interactions in a community. The role of rail transit station and the requirements of a good rail transit station are also described in this paper. Steps in selecting the location of rail transit station include the function and facilities in rail transit station are discussed with reference to best practices and handbooks. Selection of the appropriate rail transit station locations may help users indirectly. In addition, this paper will also elucidate on the design considerations for an efficient and effective rail transit station. Design selections for the rail transit station must be balanced between aesthetic value and functional efficiency. The right design selection may help conserve energy, assure and facilitate consumers even thought a rail transit station plays a smaller role in attracting consumers compared to a shopping complex or a residential building. This will contribute towards better and greener building for a green transportation facility. Thus, with this paper it is expected to assist the relevant authority to identify important elements in the selection and determination of suitable

CERN Document Server

Bosso, Nicola; Gugliotta, Antonio; Somà, Aurelio

2013-01-01

Real-time simulations of the behaviour of a rail vehicle require realistic solutions of the wheel-rail contact problem which can work in a real-time mode. Examples of such solutions for the online mode have been well known and are implemented within standard and commercial tools for the simulation codes for rail vehicle dynamics. This book is the result of the research activities carried out by the Railway Technology Lab of the Department of Mechanical and Aerospace Engineering at Politecnico di Torino. This book presents work on the project for the development of a real-time wheel-rail contact model and provides the simulation results obtained with dSpace real-time hardware. Besides this, the implementation of the contact model for the development of a real-time model for the complex mechatronic system of a scaled test rig is presented in this book and may be useful for the further validation of the real-time contact model with experiments on a full scale test rig.

Top-of-Rail lubricant

Energy Technology Data Exchange (ETDEWEB)

Alzoubi, M. F.; Fenske, G. R.; Erck, R. A.; Boparai, A. S.

2000-07-14

Analysis of the volatile and semivolatile fractions collected after use of the TOR lubricant indicated that other than contaminants in the collection laboratory, no compounds on the EPA's Target Compound Lists (Tables 2 and 5) were detected in these fractions. The data of these qualitative analyses, given in the various tables in the text, indicate only the relative amounts of the tentatively identified compounds. The authors recommend that quantitative analysis be performed on the volatile and semivolatile fractions to allow confirmation of the tentatively identified compounds and to obtain absolute amounts of the detected compounds. Additionally, the semivolatile fraction should be analyzed by liquid chromatography/mass spectrometry to identify compounds that are not chromatographable under the temperature program used for determination of semivolatile compounds. Introducing the top-of-rail (TOR) lubricant into the wheel/rail interface results in a reduction of almost 60% of lateral friction force over the forces encountered under dry conditions. This reveals good potential for energy savings, as well as wear reduction, for railroad companies. In TOR lubrication, an increase in the angle of attack and axle load results in increased lateral friction and rate of lubricant consumption. The most efficient TOR lubricant quantity to be used in the wheel/rail interface must be calculated precisely according to the number of cars, axle loads, train speed, and angle of attack.

1984-01-01

The feasibility of using rail accelerators for various in-space and to-space propulsion applications was investigated. A 1 meter, 24 sq mm bore accelerator was designed with the goal of demonstrating projectile velocities of 15 km/sec using a peak current of 200 kA. A second rail accelerator, 1 meter long with a 156.25 sq mm bore, was designed with clear polycarbonate sidewalls to permit visual observation of the plasma arc. A study of available diagnostic techniques and their application to the rail accelerator is presented. Specific topics of discussion include the use of interferometry and spectroscopy to examine the plasma armature as well as the use of optical sensors to measure rail displacement during acceleration. Standard diagnostics such as current and voltage measurements are also discussed. 15 references

Material Evaluation of an Elastomer, Epoxy and Lightweight Concrete Rail Attachment System for Direct Fixation Light Rail Applications

Science.gov (United States)

Swarner, Benjamin R.

Sound Transit plans to extend its current light rail system, which runs along the I-5 corridor in Seattle, Washington, across the I-90 Homer Hadley floating bridge as part of a project to connect the major city centers in the region. But, no light rail has ever crossed a floating bridge due to several unique engineering challenges. One of these challenges is attaching the rails to the existing bridge deck without drilling into the bridge pontoons. This research program was developed to test and analyze a direct fixation method that uses lightweight concrete plinths and an elastomer-epoxy system to attach the rails to the bridge deck. The elastomer used was a two-part, pourable elastomer with cork particles intermixed to alter the mechanical properties of the material. A lightweight concrete mixture was analyzed for use in the plinths, and system tests investigated the system response under tensile, compressive and shear loading. The shear response of the system was examined further under varying loading conditions including different surface preparations, elastomer thicknesses, strain-rates and after freeze-thaw conditioning. Experimental data was examined for trends based on these parameters to best characterize the system, and the elastomer was evaluated in the context of modern elastomer research.

Evaluating autonomous acoustic surveying techniques for rails in tidal marshes

Stiffler, Lydia L.; Anderson, James T.; Katzner, Todd

2018-01-01

There is a growing interest toward the use of autonomous recording units (ARUs) for acoustic surveying of secretive marsh bird populations. However, there is little information on how ARUs compare to human surveyors or how best to use ARU data that can be collected continuously throughout the day. We used ARUs to conduct 2 acoustic surveys for king (Rallus elegans) and clapper rails (R. crepitans) within a tidal marsh complex along the Pamunkey River, Virginia, USA, during May–July 2015. To determine the effectiveness of an ARU in replacing human personnel, we compared results of callback point‐count surveys with concurrent acoustic recordings and calculated estimates of detection probability for both rail species combined. The success of ARUs at detecting rails that human observers recorded decreased with distance (P ≤ 0.001), such that at of human‐recorded rails also were detected by the ARU, but at >75 m, only 34.0% of human‐detected rails were detected by the ARU. To determine a subsampling scheme for continuous ARU data that allows for effective surveying of presence and call rates of rails, we used ARUs to conduct 15 continuous 48‐hr passive surveys, generating 720 hr of recordings. We established 5 subsampling periods of 5, 10, 15, 30, and 45 min to evaluate ARU‐based presence and vocalization detections of rails compared with each of the full 60‐min sampling of ARU‐based detection of rails. All subsampling periods resulted in different (P ≤ 0.001) detection rates and unstandardized vocalization rates compared with the hourly sampling period. However, standardized vocalization counts from the 30‐min subsampling period were not different from vocalization counts of the full hourly sampling period. When surveying rail species in estuarine environments, species‐, habitat‐, and ARU‐specific limitations to ARU sampling should be considered when making inferences about abundances and distributions from ARU data.

2004-07-01

The diesel fuel injection equipment will remain a key element for diesel engine technology evolution. Achieving emission targets at competitive prices has been and will continue to be a major technical challenge to the engine manufacturer. Delphi is continuously developing its common rail system and its components to fulfill future stricter emission legislation while simultaneously improving performance on noise, fuel consumption and power output. This paper will describe the latest developments that delphi introduced into the market in their common rail system to comply with future legislative emission targets. Further, a novel common rail injector will be presented, that uses a revolutionary, direct acting operating principle, where the nozzle is directly operated by a piezo actuator, without the use of a servo-hydraulic flow circuit. The superior performance of this injector concept will be shown, especially in minimum quantity capability as well as multiple injection performance. The direct acting operating principle allows rapid opening and closing of the injector, without compromising pilot quantity capability. The emission benefit obtained by such opening and closing behavior will be shown. Finally, based on the findings discussed, the paper will conclude on key features of future common rail systems.

Hybrid rail gun electromagnetic accelerators

Chen, K.W.; Hachen, H.; Lee, A.; Legh, G.; Lin, T.; Mattay, S.; Wipf, S.

1983-01-01

Theoretical and experimental investigations on hybrid rail accelerators are presented. It is shown that the side surface areas and in some cases sabots of the projectile can be used to provide substantial amount of additional thrust. Moreover, it is shown that in most cases examined, external magnetic fields can be conveniently incorporated in the accelerator designs to supplement the rail-induced fields. Total thrusts in excess of 10 MN for kilogram-sized projectiles can in principle be established with driving currents of the order of 1 MA. No obvious stress limitations are foreseen. The percentages of thrust from external magnetic fields are sufficiently high that the use of which should be encouraged. The increased flexibility in the projectile shapes available permits the use of the proposed hybrid electromagnetic launcher technology in a variety of new areas, such as thrust boosts in conventional chemical rockets and other similar applications. Furthermore, the additional thrust obtained from the use of side surface areas greatly increases the maximum permissable thrust otherwise limited by material strength considerations. Thrust analyses for projectiles in several hybrid rail accelerator designs are discussed. Some laboratory experimental observations are presented

Wavenumber-domain separation of rail contribution to pass-by noise

Science.gov (United States)

Zea, Elias; Manzari, Luca; Squicciarini, Giacomo; Feng, Leping; Thompson, David; Arteaga, Ines Lopez

2017-11-01

In order to counteract the problem of railway noise and its environmental impact, passing trains in Europe must be tested in accordance to a noise legislation that demands the quantification of the noise generated by the vehicle alone. However, for frequencies between about 500 Hz and 1600 Hz, it has been found that a significant part of the measured noise is generated by the rail, which behaves like a distributed source and radiates plane waves as a result of the contact with the train's wheels. Thus the need arises for separating the rail contribution to the pass-by noise in that particular frequency range. To this end, the present paper introduces a wavenumber-domain filtering technique, referred to as wave signature extraction, which requires a line microphone array parallel to the rail, and two accelerometers on the rail in the vertical and lateral direction. The novel contributions of this research are: (i) the introduction and application of wavenumber (or plane-wave) filters to pass-by data measured with a microphone array located in the near-field of the rail, and (ii) the design of such filters without prior information of the structural properties of the rail. The latter is achieved by recording the array pressure, as well as the rail vibrations with the accelerometers, before and after the train pass-by. The performance of the proposed method is investigated with a set of pass-by measurements performed in Germany. The results seem to be promising when compared to reference data from TWINS, and the largest discrepancies occur above 1600 Hz and are attributed to plane waves radiated by the rail that so far have not been accounted for in the design of the filters.

There is a growing interest toward the use of autonomous recording units (ARUs) for acoustic surveying of secretive marsh bird populations. However, there is little information on how ARUs compare to human surveyors or how best to use ARU data that can be collected continuously throughout the day. We used ARUs to conduct 2 acoustic surveys for king (Rallus elegans) and clapper rails (R. crepitans) within a tidal marsh complex along the Pamunkey River, Virginia, USA, during May–July 2015. To determine the effectiveness of an ARU in replacing human personnel, we compared results of callback point‐count surveys with concurrent acoustic recordings and calculated estimates of detection probability for both rail species combined. The success of ARUs at detecting rails that human observers recorded decreased with distance (P ≤ 0.001), such that at 75 m, only 34.0% of human‐detected rails were detected by the ARU. To determine a subsampling scheme for continuous ARU data that allows for effective surveying of presence and call rates of rails, we used ARUs to conduct 15 continuous 48‐hr passive surveys, generating 720 hr of recordings. We established 5 subsampling periods of 5, 10, 15, 30, and 45 min to evaluate ARU‐based presence and vocalization detections of rails compared with each of the full 60‐min sampling of ARU‐based detection of rails. All subsampling periods resulted in different (P ≤ 0.001) detection rates and unstandardized vocalization rates compared with the hourly sampling period. However, standardized vocalization counts from the 30‐min subsampling period were not different from vocalization counts of the full hourly sampling period. When surveying rail species in estuarine environments, species‐, habitat‐, and ARU‐specific limitations to ARU sampling should be considered when making inferences about abundances and distributions from ARU data.

Policy issues of transporting spent nuclear fuel by rail

International Nuclear Information System (INIS)

Spraggins, H.B.

1994-01-01

The topic of this paper is safe and economical transportation of spent nuclear fuel by rail. The cost of safe movement given the liability consequences in the event of a rail accident involving such material is the core issue. Underlying this issue is the ability to access the risk probability of such an accident. The paper delineates how the rail industry and certain governmental agencies perceive and assess such important operational, safety, and economic issues. It also covers benefits and drawbacks of dedicated and regular train movement of such materials

Full Text Available European transport policy, defined in the White Paper, supports shift from road to rail and waterborne transport. The hypothesis of the paper is that changes in the economic environment influence rail traffic volume. Therefore, a model for prediction of rail traffic volume applied in different economic contexts could be a valuable tool for the transport planners. The model was built using common Machine Learning techniques that learn from the past experience. In the model preparation, world development indicators defined by the World Bank were used as input parameters.

Rail assembly for use in a radioactive environment

International Nuclear Information System (INIS)

Watts, R.E.

1989-01-01

An improved rail assembly and method of construction thereof is disclosed herein that is particularly adapted for use with a crane trolley in a hot cell environment which is exposed to airborne and liquidborne radioactive contaminants. The rail assembly is generally comprised of a support wall having an elongated, rail-housing recess having a floor, side wall and ceiling. The floor of the recess is defined at least in party by the load-bearing surface of a rail, and is substantially flat, level and crevice-free to facilitate the drainage of liquids out of the recess. The ceiling of the recess overhangs and thereby captures trolley wheels within the recess to prevent them from becoming dislodged from the recess during a seismic disturbance. Finally, the interior of the recess includes a power track having a slot for receiving a sliding electrical connector from the crane trolley. The power track is mounted in an upper corner of the recess with its connector-receiving groove oriented downwardly to facilitate the drainage of liquidborne contaminants and to discourage the collection of airborne contaminants within the track

To the question of modeling of wheels and rails wear processes

Directory of Open Access Journals (Sweden)

S.V. Myamlin

2013-06-01

Full Text Available Purpose. There is a need of wear process modeling in the wheel-rail system. This is related to the fact that the wear processes in this system are absolutely different in the initial and final stages. The profile change of rail and, especially, of the wheels caused by the wear significantly affects the rolling stock dynamics, traffic safety and the resource of the wheels and rails. Wear modeling and the traffic safety evaluation requires the accounting of the low frequency component forces (including the modeling of transitional areas affecting the wheel on the side of the rail and carriage in motion of rolling stock, so the statistical analysis is not possible. Methodology. The method of mathematical modeling of the wheel set and the rail interaction was used during the research conducting. Findings. As a result of the modeling of the wheel set motion on the rail track, the mathematic model with 19 freedom degrees was obtained. This model takes into account the axle torque and studies wheels constructions as the components of the mechanical systems, consisting of a hub and tire. Originality. The mathematic model allows evaluating the wear degree of the wheels and rails when using on the rolling stock not only all-metal wheel sets, but also compound ones with the use of spring wheels and independent rotation of semi-axes with the wheels. Practical value. The development of the improved mathematical model of freight car wheel set motion with differential rotation of the wheels and compound axles allows studying the wear processes of wheels and rails.

The wheel-rail contact friction influence on high speed vehicle model stability

Directory of Open Access Journals (Sweden)

Mirosław DUSZA

2015-09-01

Full Text Available Right estimating of the coefficient of friction between the wheel and rail is essential in modelling rail vehicle dynamics. Constant value of coefficient of friction is the typical assumption in theoretical studies. But it is obvious that in real circumstances a few factors may have significant influence on the rails surface condition and this way on the coefficient of friction value. For example the weather condition, the railway location etc. Influence of the coefficient of friction changes on high speed rail vehicle model dynamics is presented in this paper. Four axle rail vehicle model were built. The FASTSIM code is employed for calculation of the tangential contact forces between wheel and rail. One coefficient of friction value is adopted in the particular simulation process. To check the vehicle model properties under the influence of wheel-rail coefficient of friction changes, twenty four series of simulations were performed. For three curved tracks of radii R = 3000m, 6000m and  (straight track, the coefficient of friction was changed from 0.1 to 0.8. The results are presented in form of bifurcation diagrams.

Large scale implementation of guided wave based broken rail monitoring

Science.gov (United States)

Burger, Francois A.; Loveday, Philip W.; Long, Craig S.

2015-03-01

A guided wave ultrasound system has been developed over the past 17 years to detect breaks in continuously welded rail track. Installation of the version 4 system on an 840 km long heavy duty freight line was conducted between January 2013 and June 2014. The system operates in pitch - catch mode with alternate transmit and receive transducers spaced approximately 1km apart. If the acoustic signal is not received at the receive station an alarm is triggered to indicate a break in the rail between the transmit station and the receive station. The system is permanently installed, powered by solar panels and issues broken rail alarms using the GSM network where available, and digital radio technology in other areas. A total of 931 stations were installed and the entire length of rail is interrogated every fifteen minutes. The system operates reliably although some problems involving unreliable GSM communication and theft of solar panels have been experienced. In the first two months of operation four broken rails were detected and train operation was halted temporarily for repairs.

Atlanta Rail Yard Study: Evaluation of local-scale air pollution ...

Science.gov (United States)

Intermodal rail yards are important nodes in the freight transportation network, where freight is organized and moved from one mode of transport to another, critical equipment is serviced, and freight is routed to its next destination. Rail yard environments are also areas with multiple sources of air pollutant emissions (e.g., heavy-duty vehicles, locomotives, cranes), which may affect local air quality in residential areas nearby. In order to understand emissions and related air quality impacts, two field studies took place over the time span of 2010-2012 to measure air pollution trends in close proximity to the Inman and Tilford rail yard complex in Atlanta, GA. One field study involved long-term stationary monitoring of black carbon, fine particles, and carbon dioxide at two stations nearby the rail yard. In addition, a second field study performed intensive mobile air monitoring for a one month period in the summer of 2012 at a roadway network surrounding the rail yard complex and measured a comprehensive array of pollutants. Real-time mobile particulate measurements included particle counts, extinction coefficient, black carbon via light-absorption and particle incandescence, and particle composition derived by aerosol mass spectrometry. Gas-phase measurements included oxides of nitrogen, sulfur dioxide, carbon dioxide, and air toxics (e.g., benzene). Both sets of measurements determined detectable local influence from rail yard-related emissions.

A 72-dB-SNDR rail-to-rail successive approximation ADC using mismatch calibration techniques

International Nuclear Information System (INIS)

Liu Yan; Hua Siliang; Wang Donghui; Hou Chaohuan

2012-01-01

When the voltage of an analog input signal is equal to the supply voltage, it is difficult for a conventional successive approximation ADC to correctly convert the analog signal into digital signal. This paper introduces an improved successive approximation ADC, which can convert the rail-to-rail input range and reduce sampling time through a track-and-hold circuit. Comparator offset cancellation and capacitor self-calibration techniques are used in this ADC. Measurement results show that the peak SNDR of this ADC reaches 72 dB and the signal effective bandwidth is up to 1.25 MHz. It consumes 1 mW in the test, and the figure of merit is 123 fJ/conversion-step. (semiconductor integrated circuits)

Full Text Available In recent years, more studies had been conducted about train dwell time as it is a key parameter of rail system performance and reliability. This paper draws an overview of train dwell time models for rail passenger service from various continents, namely Asia, North America, Europe and Australia. The factors affecting train dwell time are identified and analysed across some rail network operators. The dwell time models developed by various researches are also discussed and reviewed. Finally, the contributions from the outcomes of these models are briefly addressed. In conclusion, this paper suggests that there is a need to further study the factors with strong influence upon dwell time to improve the quality of the train services.

We provide a theoretical framework to discuss the relation between market size and vertical structure in the railway industry. The framework is based on a simple downstream monopoly model with two input suppliers, labor forces and the rail infrastructure firm. The operation of the downstream firm (i.e., the train operating firm) generates costs on the rail infrastructure firm. We show that the downstream firm with a larger market size is more likely to integrate with the rail infrastructure f...

Wang, H P; Zheng, D; Tian, Y

2016-07-01

In this paper modeling and common-rail pressure control of high pressure common rail injection system (HPCRIS) is presented. The proposed mathematical model of high pressure common rail injection system which contains three sub-systems: high pressure pump sub-model, common rail sub-model and injector sub-model is a relative complicated nonlinear system. The mathematical model is validated by the software Matlab and a virtual detailed simulation environment. For the considered HPCRIS, an effective model free controller which is called Extended State Observer - based intelligent Proportional Integral (ESO-based iPI) controller is designed. And this proposed method is composed mainly of the referred ESO observer, and a time delay estimation based iPI controller. Finally, to demonstrate the performances of the proposed controller, the proposed ESO-based iPI controller is compared with a conventional PID controller and ADRC. Copyright © 2016 ISA.

Rail transport systems approach

CERN Document Server

2017-01-01

This book shows how the systems approach is employed by scientists in various countries to solve specific problems concerning railway transport. In particular, the book describes the experiences of scientists from Romania, Germany, the Czech Republic, the UK, Russia, Ukraine, Lithuania and Poland. For many of these countries there is a problem with the historical differences between the railways. In particular, there are railways with different rail gauges, with different signaling and communication systems, with different energy supplies and, finally, with different political systems, which are reflected in the different approaches to the management of railway economies. The book’s content is divided into two main parts, the first of which provides a systematic analysis of individual means of providing and maintaining rail transport. In turn, the second part addresses infrastructure and management development, with particular attention to security issues. Though primarily written for professionals involved...

The experimental determination of the relationship between the energising time of the common rail injector and the set fuel quantity and rail pressure

Directory of Open Access Journals (Sweden)

Pietras Dariusz

2017-01-01

Full Text Available The article discusses the issue of experimentally determining the relationship between the energising time of the common rail electromagnetic injector and the set fuel quantity and rail pressure. Experimental studies according to the assumed methodology were made on a test bench enabling the dynamic flow rate measurement of the injector. The fuel system mounted on the test bench was controlled by the laboratory CI engine control unit based on the original concept of one of the authors of the article. The results of the experimental studies have made it possible to determine many of the characteristics of the fuel flow rate depending on the specified rail pressure and the energising time of the injector. An analysis was then performed followed by extrapolation of the obtained results. The data obtained from these analyses are the basis for the development of the energising time control algorithm based on a set fuel quantity and rail pressure.

2015-01-01

The life of railway wheels and rails has been decreasing in recent years. This is mainly caused by more traffic and running at higher vehicle speed. A higher speed usually generates higher forces, unless compensated by improved track and vehicle designs, in the wheel-rail contact, resulting in more wear and rolling contact fatigue (RCF) damage to the wheels and rails. As recently as 15 years ago, RCF was not recognised as a serious problem. Nowadays it is a serious problem in many countries a...

Shock and vibration environments for large shipping containers on rail cars and trucks

International Nuclear Information System (INIS)

Magnuson, C.F.; Wilson, L.T.

1977-06-01

The purpose of this study was to provide definitions of shock and vibration environment to which fissile material shipping containers may be exposed during normal shipment by truck and rail cars. The definitions of vibration, shock superimposed on vibration and rail coupling shock result from existing data. The dependence of shock environment, from rail coupling operations, on parameters like cargo weight and shock attenuation couplers was also studied using spring-mass models. These studies show that for rail cars equipped with standard draft gear, the cargo response decreases with increased cargo weight until the springs bottom out. For rail cars equipped with shock attenuation couplers, cargo weight has little effect on cargo response. The study also shows the importance of matching couplers and tiedown stiffnesses to decrease the cargo response. Vibration and shock data samples have been obtained during truck shipment of heavy cargo and the data will be presented in subsequent reports. Similar data need to be obtained for rail shipment of heavy cargo and during rail coupling operations with heavy cargo

Modelling of contact problems involved in ensuring the safety of rail transport

Directory of Open Access Journals (Sweden)

Edward Rydygier

2013-12-01

Full Text Available Background: Mathematical modelling aids diagnostics the track and rolling stock, as it often for technical reasons it is not possible to obtain a complete set of measurement data required to diagnose the rail and wheel deformation caused by the impact of a rail vehicle on the track. The important issue in a railway diagnostics is to study the effects of contact wheel and rail. Diagnostics investigations of track and rolling stock have a fundamental role in ensuring the safety of transport of passengers and goods. The aim of the study presented in the paper was to develop simulation methods of mathematical modelling of the wheel-rail system useful in the diagnostics of the track and a railway vehicle. Methods: In the paper two ways of modelling were presented and discussed. One of these ways is the method which consists in reducing the contact issue to field issue and solving the identification of the field source in 2-D system. Also presented a different method designed on the basis of the methods using one period energy concept. This method is adapted for modelling the dynamics of the contact wheel-rail for the normal force. It has been shown that the developed modelling methods to effectively support the study on the effects of mechanical and thermal of contact wheel-rail and contribute to the safety of operations.  Results and conclusions:  In the case of field sources identifications two specific issues were examined: the issue of rail torsion and the identification of heat sources in the rail due to exposure the rolling contact wheel-rail. In the case of the method using one period energy concept it was demonstrated the usefulness of this method to the study of energy processes in the contact wheel-rail under the normal periodic force. The future direction of research is to establish cooperation with research teams entrusted with the diagnostic measurements of track and rolling stock.

The objective of the rail shock and vibration tests is to complete the framework needed to quantify loads of fuel assembly components that are necessary to guide materials research and establish a technical basis for review organizations such as the U.S. Nuclear Regulatory Commission (NRC). A significant body of experimental and numerical modeling data exists to quantify loads and failure limits applicable to normal conditions of transport (NCT) rail transport, but the data are based on assumptions that can only be verified through experimental testing. The test options presented in this report represent possible paths for acquiring the data that are needed to confirm the assumptions of previous work, validate modeling methods that will be needed for evaluating transported fuel on a case-by-case basis, and inform material test campaigns on the anticipated range of fuel loading. The ultimate goal of this testing is to close all of the existing knowledge gaps related to the loading of used fuel under NCT conditions and inform the experiments and analysis program on specific endpoints for their research. The options include tests that would use an actual railcar, surrogate assemblies, and real or simulated rail transportation casks. The railcar carrying the cradle, cask, and surrogate fuel assembly payload would be moved in a train operating over rail track modified or selected to impart shock and vibration forces that occur during normal rail transportation. Computer modeling would be used to help design surrogates that may be needed for a rail cask, a cask’s internal basket, and a transport cradle. The objective of the design of surrogate components would be to provide a test platform that effectively simulates responses to rail shock and vibration loads that would be exhibited by state-of-the-art rail cask, basket, and/or cradle structures. The computer models would also be used to help determine the placement of instrumentation (accelerometers and strain gauges

Rail deployment and storage procedure and test for ITER blanket remote maintenance

International Nuclear Information System (INIS)

Kakudate, S.; Shibanuma, K.

2003-01-01

A concept of rail-mounted vehicle manipulator system has been developed to apply to the maintenance of the ITER blanket composed of ∼400 modules in the vacuum vessel. The most critical issue of the vehicle manipulator system is the feasibility of the deployment and storage of the articulated rail, composed of eight rail links without any driving mechanism in the joints. To solve this issue, a new driving mechanism and procedure for the rail deployment and storage has been proposed, taking account of the repeated operation of the multi-rail links deployed and stored in the same kinematical manner. The new driving mechanism, which is different from those of a usual articulated manipulator or 'articulated boom' equipped with actuators in every joint for movement, is composed of three external mechanisms installed outside the articulated rail, i.e. a vehicle traveling mechanism as main driver and two auxiliary driving mechanisms. A simplified synchronized control of three driving mechanisms has also been proposed, including 'torque-limit control' for suppression of the overload of the mechanisms. These proposals have been tested using a full-scale vehicle manipulator system, in order to demonstrate the proof of principle for rail deployment and storage. As a result, the articulated rail has been successfully deployed and stored within 6 h each, less than the target of 8 h, by means of the three external driving mechanisms and the proposed synchronized control. In addition, the overload caused by an unexpected mismatch of the synchronized control of three driving mechanisms has also been successfully suppressed less than the rated torque by the proposed 'torque-limit control'. It is therefore concluded that the feasibility of the rail deployment and storage of the vehicle manipulator system has been demonstrated

Optimal energy management of urban rail systems: Key performance indicators

International Nuclear Information System (INIS)

González-Gil, A.; Palacin, R.; Batty, P.

2015-01-01

Highlights: • An overall picture of urban rail energy use is provided. • Performance indicators are developed for urban rail system energy optimisation. • A multi-level methodology for assessing energy efficiency measures is presented. - Abstract: Urban rail systems are facing increasing pressure to minimise their energy consumption and thusly reduce their operational costs and environmental impact. However, given the complexity of such systems, this can only be effectively achieved through a holistic approach which considers the numerous interdependences between subsystems (i.e. vehicles, operations and infrastructure). Such an approach requires a comprehensive set of energy consumption-related Key Performance Indicators (KEPIs) that enable: a multilevel analysis of the actual energy performance of the system; an assessment of potential energy saving strategies; and the monitoring of the results of implemented measures. This paper proposes an original, complete list of KEPIs developed through a scientific approach validated by different stakeholders. It consists of a hierarchical list of 22 indicators divided into two levels: 10 key performance indicators, to ascertain the performance of the whole system and complete subsystems; and 12 performance indicators, to evaluate the performance of single units within subsystems, for example, a single rail vehicle or station. Additionally, the paper gives a brief insight into urban rail energy usage by providing an adequate context in which to understand the proposed KEPIs, together with a methodology describing their application when optimising the energy consumption of urban rail systems

Comparison of experimental and theoretical reaction rail currents, rail voltages, and airgap fields for the linear induction motor research vehicle

Science.gov (United States)

Elliott, D. G.

1977-01-01

Measurements of reaction rail currents, reaction rail voltages, and airgap magnetic fields in tests of the Linear Induction Motor Research Vehicle (LIMRV) were compared with theoretical calculations from the mesh/matrix theory. It was found that the rail currents and magnetic fields predicted by the theory are within 20 percent of the measured currents and fields at most motor locations in most of the runs, but differ by as much as a factor of two in some cases. The most consistent difference is a higher experimental than theoretical magnetic field near the entrance of the motor and a lower experimental than theoretical magnetic field near the exit. The observed differences between the theoretical and experimental magnetic fields and currents do not account for the differences of as much as 26 percent between the theoretical and experimental thrusts.

Barker, Emma; Kolves, Kairi; De Leo, Diego

2017-09-01

Rail-related suicide is a relatively rare but extremely lethal method of suicide that can have far-reaching consequences. The aim of the systematic literature review was to analyze the existing literature on the effectiveness of rail-suicide prevention activities. Databases used were Scopus, Medline, and ProQuest. The search terms used were "suicid*," "prevent*," "rail*," or "train." English-language studies published in peer-reviewed journals between 1 January 1990 and 30 April 2015 that presented an overview of rail-related suicide prevention activities and included an analysis of effectiveness were used. We retrieved 1,229 results in the original search with nine papers presenting empirical evidence. Three studies in the review analyzed the effectiveness of platform screen doors and another three analyzed the installation of blue lights, two papers analyzed the effectiveness of suicide pits, and one included the influence of media reporting guidelines. Platform screen doors, suicide pits, blue lights, and improved media guidelines all have the potential to reduce rail-related suicide events and deaths. The review was restricted to English-language peer-reviewed papers published within the chosen time period. © 2016 John Wiley & Sons Australia, Ltd.

Study on Rail Profile Optimization Based on the Nonlinear Relationship between Profile and Wear Rate

Directory of Open Access Journals (Sweden)

Jianxi Wang

2017-01-01

Full Text Available This paper proposes a rail profile optimization method that takes account of wear rate within design cycle so as to minimize rail wear at the curve in heavy haul railway and extend the service life of rail. Taking rail wear rate as the object function, the vertical coordinate of rail profile at range optimization as independent variable, and the geometric characteristics and grinding depth of rail profile as constraint conditions, the support vector machine regression theory was used to fit the nonlinear relationship between rail profile and its wear rate. Then, the profile optimization model was built. Based on the optimization principle of genetic algorithm, the profile optimization model was solved to achieve the optimal rail profile. A multibody dynamics model was used to check the dynamic performance of carriage running on optimal rail profile. The result showed that the average relative error of support vector machine regression model remained less than 10% after a number of training processes. The dynamic performance of carriage running on optimized rail profile met the requirements on safety index and stability. The wear rate of optimized profile was lower than that of standard profile by 5.8%; the allowable carrying gross weight increased by 12.7%.

A new solution method for wheel/rail rolling contact.

Science.gov (United States)

Yang, Jian; Song, Hua; Fu, Lihua; Wang, Meng; Li, Wei

2016-01-01

To solve the problem of wheel/rail rolling contact of nonlinear steady-state curving, a three-dimensional transient finite element (FE) model is developed by the explicit software ANSYS/LS-DYNA. To improve the solving speed and efficiency, an explicit-explicit order solution method is put forward based on analysis of the features of implicit and explicit algorithm. The solution method was first applied to calculate the pre-loading of wheel/rail rolling contact with explicit algorithm, and then the results became the initial conditions in solving the dynamic process of wheel/rail rolling contact with explicit algorithm as well. Simultaneously, the common implicit-explicit order solution method is used to solve the FE model. Results show that the explicit-explicit order solution method has faster operation speed and higher efficiency than the implicit-explicit order solution method while the solution accuracy is almost the same. Hence, the explicit-explicit order solution method is more suitable for the wheel/rail rolling contact model with large scale and high nonlinearity.

Deviation rectification for dynamic measurement of rail wear based on coordinate sets projection

International Nuclear Information System (INIS)

Wang, Chao; Ma, Ziji; Li, Yanfu; Liu, Hongli; Zeng, Jiuzhen; Jin, Tan

2017-01-01

Dynamic measurement of rail wear using a laser imaging system suffers from random vibrations in the laser-based imaging sensor which cause distorted rail profiles. In this paper, a simple and effective method for rectifying profile deviation is presented to address this issue. There are two main steps: profile recognition and distortion calibration. According to the constant camera and projector parameters, efficient recognition of measured profiles is achieved by analyzing the geometric difference between normal profiles and distorted ones. For a distorted profile, by constructing coordinate sets projecting from it to the standard one on triple projecting primitives, including the rail head inner line, rail waist curve and rail jaw, iterative extrinsic camera parameter self-compensation is implemented. The distortion is calibrated by projecting the distorted profile onto the x – y plane of a measuring coordinate frame, which is parallel to the rail cross section, to eliminate the influence of random vibrations in the laser-based imaging sensor. As well as evaluating the implementation with comprehensive experiments, we also compare our method with other published works. The results exhibit the effectiveness and superiority of our method for the dynamic measurement of rail wear. (paper)

With the serial start of the Direct Acting Common Rail injection system with 2.000 bar Delphi Diesel Systems could supplement its product portfolio with a valuable component. In Delphi's directly propelled Common Rail injector, the Injection needle directly is set in operation with the help of a piezo-ceramic actuator instead of only controlling this with a conventional servo-hydraulic circuit indirectly. This enables a fast opening and closing of the nozzle needle possible independently from the rail pressure. The process of injection is controllable accurately at any time with the again developed two-stage needle movement amplifier. The additionally in the injector integrated fuel storage works as a 'Rail in the Injector' and improves the quality particularly during multiple injection. The injector completely works leakage-free and thereby helps to reach the future CO{sub 2} targets. The use of piezo-actuators as driving force behind the directly working injector leads to a set of requirements to the electronics. A control electronics was developed in order to head optimally the Direct Acting Injector. The sum of all advantages of the Direct Acting of CR systems enables lowest emissions with simultaneously small fuel consumption while new dimensions are reached with power density and engine torque. The authors of the contribution under consideration report on the construction, on the work principle of the Direct Acting CR system and on its performance characteristics as a basis for the premium diesel engine.

The connection between profile grinding of rails, martensite surface layers and crack initiation has been investigated using visual inspection, optical microscopy and 3D X-ray computerized tomography. Newly grinded rails were extracted and found to be covered by a continuous surface layer...... of martensite with varying thickness formed by the grinding process. Worn R350HT and R200 rails were extracted from the Danish rail network as they had transverse bands resembling grinding marks on the running surface. The transverse bands were shown to consist of martensite which had extensive crack formation...... at the martensite/pearlite interface. The cracks in R350HT propagated down into the rail while those in the soft R200 returned to the surface causing only very small shallow spallation. The transverse bands had the same shape, size, orientation, location and periodicity which would be expected from grinding marks...

Fuel Savings and Aerodynamic Drag Reduction from Rail Car Covers

Science.gov (United States)

Storms, Bruce; Salari, Kambiz; Babb, Alex

2008-01-01

The potential for energy savings by reducing the aerodynamic drag of rail cars is significant. A previous study of aerodynamic drag of coal cars suggests that a 25% reduction in drag of empty cars would correspond to a 5% fuel savings for a round trip [1]. Rail statistics for the United States [2] report that approximately 5.7 billion liters of diesel fuel were consumed for coal transportation in 2002, so a 5% fuel savings would total 284 million liters. This corresponds to 2% of Class I railroad fuel consumption nationwide. As part of a DOE-sponsored study, the aerodynamic drag of scale rail cars was measured in a wind tunnel. The goal of the study was to measure the drag reduction of various rail-car cover designs. The cover designs tested yielded an average drag reduction of 43% relative to empty cars corresponding to an estimated round-trip fuel savings of 9%.

We studied the causes of mortality for the California Ridgway’s rail at multiple tidal marshes in the San Francisco Bay Estuary, California. We radio-marked 196 individual rails and examined the evidence from 152 recovered California Ridgway’s rail mortalities from our radio-marked sample and determined plausible cause of death from a wide array of evidence. We also included 10 additional California Ridgway’s rail mortalities (unmarked) that we encountered during our normal field operations. We assigned a likely cause of death to 130 of the recoveries, of which 127 were determined to be caused by predation. Of those, 103 could be divided into class of cause (avian or mammalian), and avian predators were responsible for 64% of those events. Primary predators identified include domestic or feral cats, red fox, owl, and northern harrier. We did find seasonal differences between avian and mammalian predation rates, with higher proportions of avian predation in the winter and early spring. Time of day and tide height

Effects of anchoring and arc structure on the control authority of a rail plasma actuator

International Nuclear Information System (INIS)

Choi, Young-Joon; Gray, Miles; Sirohi, Jayant; Raja, Laxminarayan L

2017-01-01

Experiments were conducted on a rail plasma actuator (RailPAc) with different electrode cross sections (rails or rods) to assess methods to improve the actuation authority, defined as the impulse generated for a given electrical input. The arc was characterized with electrical measurements and high-speed images, while impulse measurements quantified the actuation authority. A RailPAc power supply capable of delivering  ∼1 kA of current at  ∼100 V was connected to rod electrodes (free-floating with circular cross-section) and rail electrodes (flush-mounted in a flat plate with rectangular cross-section). High-speed images show that the rail electrodes cause the arc to anchor itself to the anode electrode and transit in discrete jumps, while rod electrodes permit the arc to transit smoothly without anchoring. The impulse measurements reveal that the anchoring reduces the actuation authority by  ∼21% compared to a smooth transit, and the effect of anchoring can be suppressed by reducing the gap between the rails to 2 mm. The study further demonstrates that if a smooth transit is achieved, the control authority can be increased with a larger gap and larger arc current. In conclusion, the actuation authority of a RailPAc can be maximized by carefully choosing a gap width that prevents anchoring. Further study is warranted to increase the RailPAc actuation authority by introducing multiple turns of wires beneath the RailPAc to augment the induced magnetic field. (paper)

Development of rail access to the proposed repository site at Yucca Mountain

International Nuclear Information System (INIS)

Standish, P.N.; Seidler, P.E.; Andrews, W.B.; Shearin, G.

1991-01-01

In accordance with the Nuclear Waste Policy Amendment Act of 1987, Yucca Mountain was designated as the initial site to be investigated as a potential repository for the disposal of high-level radioactive waste. The Yucca Mountain site is an undeveloped area located on the southwestern edge of the Nevada Test Site (NTS), about 100 miles northwest of Las Vegas. The site currently lacks rail service or an existing right-of-way. If the Yucca Mountain site is found suitable for the repository, rail service is considered desirable by the Office of Civilian Radioactive Waste Management (OCRWM) program because of the potential of rail transportation to reduce (1) costs and (2) number of shipments, relative to highway transportation. Therefore, it is necessary to conduct a study to determine (1) that there are alignments for a potential rail line from existing mainline railroads to Yucca Mountain and (2) that these are consistent with present rail design standards and are acceptable relative to environmental and land access considerations

Bubble propagation on a rail: a concept for sorting bubbles by size

Science.gov (United States)

Franco-Gómez, Andrés; Thompson, Alice B.; Hazel, Andrew L.; Juel, Anne

We demonstrate experimentally that the introduction of a rail, a small height constriction, within the cross-section of a rectangular channel could be used as a robust passive sorting device in two-phase fluid flows. Single air bubbles carried within silicone oil are generally transported on one side of the rail. However, for flow rates marginally larger than a critical value, a narrow band of bubble sizes can propagate (stably) over the rail, while bubbles of other sizes segregate to the side of the rail. The width of this band of bubble sizes increases with flow rate and the size of the most stable bubble can be tuned by varying the rail width. We present a complementary theoretical analysis based on a depth-averaged theory, which is in qualitative agreement with the experiments. The theoretical study reveals that the mechanism relies on a non-trivial interaction between capillary and viscous forces that is fully dynamic, rather than being a simple modification of capillary static solutions.

Parking Space Occupancy at Rail Stations in Klang Valley

Directory of Open Access Journals (Sweden)

Ho Phooi Wai

2017-01-01

Full Text Available The development of Klang Valley Integrated Rapid Transit system in Klang Valley, Malaysia has been quickly gaining momentum during the recent years. There will be two new MRT lines (MRT Line 1 and MRT Line 2 and one new LRT line (LRT Line 3 extended from the current integrated rail transit system by year 2020 with more than 90 new rail stations. With the substantial addition of potential rail passengers, there are doubts whether the existing Park and Ride facilities in Klang Valley are able to accommodate the future parking space demand at rail stations. This research studies the parking occupancy at various Park and Ride facilities in Klang Valley namely Taman Jaya, Asia Jaya, Taman Paramount, Taman Bahagia and Kelana Jaya by applying the non-conventional method utilizing Google Earth imageries. Results showed that the parking occupancy rate at these LRT stations were 100% or more before the commencement of LRT extension (Kelana Jaya and Ampang Lines in 2016 and in the range of 36% to 100% after the commencement of LRT extension due to the additionally built car parks and changes in parking pattern with dispersed passenger traffic.

BIM Interoperability Limitations: Australian and Malaysian Rail Projects

Directory of Open Access Journals (Sweden)

Kenley Russell

2016-01-01

Full Text Available Building information modelling (BIM is defined as a process involving the generation and management of digital representation of physical and functional characteristics of a facility. The purpose of interoperability in integrated or “open” BIM is to facilitate the information exchange between different digital systems, models and tools. There has been effort towards data interoperability with development of open source standards and object-oriented models, such as industry foundation classes (IFC for vertical infrastructure. However, the lack of open data standards for the information exchange for horizontal infrastructure limits the adoption and effectiveness of integrated BIM. The paper outlines two interoperability issues for construction of rail infrastructure. The issues are presented in two case study reports, one from Australia and one from Malaysia. The each case study includes: a description of the project, the application of BIM in the project, a discussion of the promised BIM interoperability solution plus the identification of the unresolved lack of interoperability for horizontal infrastructure project management. The Moreton Bay Rail project in Australia introduces general software interoperability issues. The Light Rail Extension project in Kuala Lumpur outlines an example of the integration problems related to two different location data structures. The paper highlights how the continuing lack of data interoperability limits utilisation of integrated BIM for horizontal infrastructure rail projects.

Many communities in the United States have been adding new light rail to bus-predominant public transit systems. However, there is disagreement as to whether opening light rail lines attracts new ridership or merely draws ridership from existing transit users. We study a new light rail line in Salt Lake City, Utah, USA, which is part of a complete street redevelopment. We utilize a pre-test post-test control group quasi-experimental design to test two different measures of ridership change. The first measure is calculated from stops along the light rail route; the second assumes that nearby bus stops might be displaced by the rail and calculates ridership change with those stops included as baseline. Both the simple measure (transit use changes on the complete street light rail corridor) and the "displacement" measure (transit use changes in the one-quarter mile catchment areas around new light rail stops) showed significant ( p rail bus users. In particular, the displacement analysis discredits a common challenge that when a new light rail line opens, most passengers are simply former bus riders whose routes were canceled in favor of light rail. The study suggests that light rail services can attract additional ridership to public transit systems. In addition, although pre-post control-group designs require time and effort, this project underscores the benefits of such quasi-experimental designs in terms of the strength of the inferences that can be drawn about the impacts of new transit infrastructure and services.

2016-07-01

Very few contributions in the literature have dealt with the issue of social exclusion related to High Speed Rail systems. The objective of this manuscript is to understand what are the factors excluding users from choosing High Speed Rail services considering as case study Spain. For this purpose, a Revealed Preference survey was employed in November and December 2015. A questionnaire was submitted to users of the Spanish transport systems travelling for long distance-journeys. The aim was that of investigating their perception of High Speed Rail system and the factors inhibiting passengers or excluding them from its use. Data about their socioeconomic characteristics were collected as well. The main result of the survey has been that a relationship between social exclusion and High Speed Rail in Spain is present, especially in terms of geographical exclusion. (Author)

USDOE Top-of-Rail Lubricant Project; FINAL

International Nuclear Information System (INIS)

Mohumad F. Alzoubi; George R. Fenske; Robert A. Erck; Amrit S. Boparai

2002-01-01

Lubrication of wheel/rail systems has been recognized for the last two decades as a very important issue for railroads. Energy savings and less friction and wear can be realized if a lubricant can be used at the wheel/rail interface. On the other hand, adverse influences are seen in operating and wear conditions if improper or excessive lubrication is used. Also, inefficiencies in lubrication need to be avoided for economic and environmental reasons. The top-of-rail (TOR) lubricant concept was developed by Texaco Corporation to lubricate wheels and rails effectively and efficiently. Tranergy Corporation has been developing its SENTRAEN 2000(trademark) lubrication system for the last ten years, and this revolutionary new high-tech on-board rail lubrication system promises to dramatically improve the energy efficiency, performance, safety, and track environment of railroads. The system is fully computer-controlled and ensures that all of the lubricant is consumed as the end of the train passes. Lubricant quantity dispensed is a function of grade, speed, curve, and axle load. Tranergy also has its LA4000(trademark) wheel and rail simulator, a lubrication and traction testing apparatus. The primary task of this project was collecting and analyzing the volatile and semivolatile compounds produced as the lubricant was used. The volatile organic compounds were collected by Carbotrap cartridges and analyzed by adsorption and gas chromatography/mass spectrometry (GC/MS). The semivolatile fraction was obtained by collecting liquid that dripped from the test wheel. The collected material was also analyzed by GC/MS. Both of these analyses were qualitative. The results indicated that in the volatile fraction, the only compounds on the Environmental Protection Agency's (EPA) Superfund List of Analytes detected were contaminants either in the room air or from other potential contamination sources in the laboratory. Similarly, in the semivolatile fraction none of the detected

South Africa’s freight rail reform: A demand-driven perspective

Directory of Open Access Journals (Sweden)

Jan H. Havenga

2014-11-01

Full Text Available During the 20th century, freight transport in South Africa was employed to attain politicoeconomic ideals, resulting in the overprotection of rail and overregulation of road transport. Increasing industry pressure, combined with the international deregulation trend, led to deregulation in 1988. Myopia resulted in a rail investment hiatus and exponential growth in high-value, long-distance road transport, causing excessive logistics and externality costs for the country. The aim of this study was to propose a freight rail reform agenda based on, (1 lessons from past freight transport policy efforts and (2 the results of freight transport market segmentation driven by models developed over the past two decades. For the study, freight flows were modelled by disaggregating the national input–output model into 372 origin–destination pairs and 71 commodity groups, followed by distance decay gravitymodelling. Logistics costs were calculated by relating commodity-level freight flows to the costs of fulfilling associated logistical functions. The standard management approach of founding strategy development on market-driven segmentation provides a neutral input to steer rail reform discussions in South Africa. Market segmentation points to a dualistic rail reform agenda, enabling both a profit-driven core and a development-driven branch line network. Freight flow insights are steering the policy reform debate towards long-term freight strategy development and optimal freight logistics network design.

System diagnosis using finite memory observers: Common Rail application; Diagnostic des systemes a l'aide d'observateurs a memoire finie: application au Common Rail

Energy Technology Data Exchange (ETDEWEB)

Graton, G.

2005-12-15

The aim of this work was to propose a fault detection method on the high pressure direct injection system (called Common Rail system) set up on Diesel vehicles. The importance of the fault detection procedure implementation was highlighted thanks to the description of the stakes (lowers consumption, reduction in the pollutant emissions and sound, increase of performances) and constraints dependent on Common Rail (high pressure, high frequency, gas oil lubrication, high precision machining, standards EURO respect,...) but also through a listing of failures which can occur on Common Rail. A synthesis on the different diagnosis methods of systems contributed to select a fault detection method with expected performances (detection of fault beginning, detection speed, isolation and characterization of detected fault and minimizing false alarm and bad detections). After a detailed study (properties, sequential formulations and sensitivity study) of the selected detection method (finite memory observers) and a modeling of the Common Rail various bodies behavior, the algorithm of detection was tested on three different models of the system Common Rail. Moreover, the comparison between the finite memory observer and a Luenberger observer and a Kalman filter allow to appreciate the residual robustness degree. Obtained results allow to conclude on good detection of actuator and sensor faults. (author)

A REVIEW OF HIGH-SPEED RAIL PLAN IN JAVA ISLAND: A COMPARISON WITH EXISTING MODES OF TRANSPORT

Directory of Open Access Journals (Sweden)

Eko Hartono

2013-05-01

It can be concluded that journey time and fare of the high-speed rail is very competitive to the air transport in Jakarta-Surabaya corridor. The journey time to travel from Jakarta to Surabaya is 4 hours and 19 minutes by high-speed train and 4 hours and 40 minutes by air. Based on the benchmarking analysis, the suitable fare for the high-speed rail should be 70% of the air transport. This study predicted that 61% of air passenger, 18% of conventional rail passenger and 12% of bus passenger will switch to the high-speed rail service in 2020. In total, the high-speed rail will have 24% of market share for the passenger transport and becomes the second largest market share after road transport (52%. The conventional rail and air transport have 14% and 9% of total market share to travel from Jakarta to Surabaya and vice versa. The high-speed rail development reduces carbon emissions caused by transportation systems in Java Island. It has been calculated that there are 2.542 million tonnages of CO2 per annum without introducing high-speed rail, however, the CO2 emissions decrease to 1.694 million tonnages per annum if the high-speed rail is developed in Java Island. Generalized cost of the high-speed rail is higher than road and conventional rail. However, it is lower than air transport. Keywords: Java high-speed rail, HSR Comparison, modal share, journey time

Research on the Common Rail Pressure Overshoot of Opposed-Piston Two-Stroke Diesel Engines

Directory of Open Access Journals (Sweden)

Yi Lu

2017-04-01

Full Text Available The common rail pressure has a direct influence on the working stability of Opposed-Piston Two-Stroke (OP2S diesel engines, especially on performance indexes such as power, economy and emissions. Meanwhile, the rail pressure overshoot phenomenon occurs frequently due to the operating characteristics of OP2S diesel engines, which could lead to serious consequences. In order to solve the rail pressure overshoot problem of OP2S diesel engines, a nonlinear concerted algorithm adding a speed state feedback was investigated. First, the nonlinear Linear Parameter Varying (LPV model was utilized to describe the coupling relationship between the engine speed and the rail pressure. The Linear Quadratic Regulator (LQR optimal control algorithm was applied to design the controller by the feedback of speed and rail pressure. Second, cooperating with the switching characteristics of injectors, the co-simulation of MATLAB/Simulink and GT-Power was utilized to verify the validity of the control algorithm and analyze workspaces for both normal and special sections. Finally, bench test results showed that the accuracy of the rail pressure control was in the range of ±1 MPa, in the condition of sudden 600 r/min speed increases. In addition, the fuel mass was reduced 76.3% compared with the maximum fuel supply quantity and the rail pressure fluctuation was less than 20 MPa. The algorithm could also be appropriate for other types of common rail system thanks to its universality.

The ever increasing problems faced by population around the world have made demands that transportation need to be improved as an effective and efficient communication means. It is considered as a necessity especially when rapid development and economic growth of a country is the agenda. Among the transportation modes being focused as critical facilities are the bus system, rail system, road network, shipping system and air transportation system. Rail transport is a means of conveyance of passengers and goods by way of wheeled vehicles running on rail tracks. In Malaysia, the railway network has evolved tremendously since its inception in the early 19th century. It has grown proportionally with the national development. Railway network does not only mean for rural transportation, but it also considered as a solution to urban congestion challenges. Currently, urban rail transit is the most popular means of urban transportation system especially as big cities such as Kuala Lumpur. This paper presents the definition of rail transportation system and its role in urban or sub-urban operation. It also describes the brief history of world railway transportation including a discussion on Malaysian rail history perspective. As policy and standard are important in operating a railway system, this paper also illustrates and discusses some elements which have an impact on the effectiveness and efficiency of train operation. Towards the end, this paper also shares the importance of railway safety based on real case studies around the world. Thus, it is hoped that this paper will enable the public to understand the rail transit development and appreciate its existence as a public transportation system.

2017-08-01

Sleep and work schedules differ considerably between rail workers and the broader U.S. workforce. Due to extended work hours and night shift schedules, train and engine service workers who operate passenger trains or move freight are most vulnerable to fatigue. This article addresses the need for comprehensive fatigue risk management systems (FRMS) for rail operators. Using a transactional ergonomic perspective, FRMS are discussed with a focus on fatigue education and administrative controls to reduce feelings of tiredness, low motivation, poor concentration, and low physical activity among mass transit rail operators. Recommendations for intervention implementation and evaluation are provided.

Spain out of Spain. Spanish Patriotism in the Argentinian emigration: an approach

Directory of Open Access Journals (Sweden)

Marcela García Sebastiani

2013-08-01

Full Text Available During the first third of the 20th century, Spanish migrants in Argentina prompted, from specific areas of civil society and the public sphere, corporate identity for political purposes. It was a residual patriotism and condemned from the outset. It was activated in specific circumstances and in relation to the local policies projected towards the collective migratory, the Spanish politics, and recognition of shared sociopolitical and cultural genealogies. From the perspective of cultural history of the policy, and based on primary and secondary sources, this article discusses about built imaginaries, social mobilization generated and results between 1885 and 1920. During that time, from distance, migrants also built ideas about Spain and drawn up national myths in the cultural version of liberalism that eventually led to a conservative nationalist, catholic and –at times– fascist.

Masirin, Mohd Idrus Mohd; Salin, Aminah Mohd; Zainorabidin, Adnan; Martin, David; Samsuddin, Norshakina

2017-08-01

In any context, operation and management of transportation systems are key issues which may affect both life quality and economic development. In large urban agglomerations, an efficient public transportation system may help abate the negative externalities of private car use such as congestion, air and noise pollution, accident and fuel consumption, without excessively penalizing user travel times or zone accessibility. Thus, this study is conducted to appraise the Malaysian rural rail transit operation and management system, which are considered important as there are many issues and solution in integration of the services that need to be tackled more conscientiously. The purpose of this paper is to describe some of the most important issues on integration of services and rail transit system in Malaysian and how to solve or reduce these problems and conflicts. In this paper, it consists of the historical development of rail transit construction in Malaysia. This paper also attempts to identify the important issues related to rail transit services and integration in Malaysian rural rail operation and management system. Comparison is also conducted with other countries such as UK, France, and Japan. Finally, a critical analysis is presented in this paper by looking at the possible application for future Malaysian rail transit operation system and management, especially focusing on enhancing the quality of Malaysian rural rail transit. In conclusion, this paper is expected to successfully review and appraise the existing Malaysian rural rail transit operation and management system pertaining to issues & solution in integration. It is also hoped that reformation or transformation of present service delivery quality of the rail transit operation and management will enable Malaysia to succeed in transforming Malaysian transportation system to greater heights.

Rail Brake System Using a Linear Induction Motor for Dynamic Braking

Science.gov (United States)

Sakamoto, Yasuaki; Kashiwagi, Takayuki; Tanaka, Minoru; Hasegawa, Hitoshi; Sasakawa, Takashi; Fujii, Nobuo

One type of braking system for railway vehicles is the eddy current brake. Because this type of brake has the problem of rail heating, it has not been used for practical applications in Japan. Therefore, we proposed the use of a linear induction motor (LIM) for dynamic braking in eddy current brake systems. The LIM reduces rail heating and uses an inverter for self excitation. In this paper, we estimated the performance of an LIM from experimental results of a fundamental test machine and confirmed that the LIM generates an approximately constant braking force under constant current excitation. At relatively low frequencies, this braking force remains unaffected by frequency changes. The reduction ratio of rail heating is also approximately proportional to the frequency. We also confirmed that dynamic braking resulting in no electrical output can be used for drive control of the LIM. These characteristics are convenient for the realization of the LIM rail brake system.

Webster, P.J.; Low, K.S.; Mills, G.; Webster, G.A.

1990-01-01

The high resolution neutron diffraction technique has been applied to determine, non-destructively, the residual stress distribution developed in the head of a railway rail after normal service. Measurements were made, using the neutron strain scanner at the Institute Laue Langevin, Grenoble, on a transverse slice of rail 12mm thick taken from a section of straight track. The rail head was scanned in the three principal orientations in a series of parallel traverses sufficiently close to enable a two-dimensional matrix of data to be accumulated and vertical, transverse and longitudinal residual stress contours to be drawn. The results demonstrate the effectiveness and unique characteristics of the neutron technique to determine nondestructively and continuously the residual stresses inside engineering components

Long Term Land Use Effects of New Rail Investment: Lessons from San Diego

Directory of Open Access Journals (Sweden)

David A. King

2018-01-01

Full Text Available In recent decades, U.S. cities have invested in rail transit for reasons beyond supplying alternatives to driving. Increasingly, rail investments are specifically promoted to reshape the built environment for property-led economic development. In these cases, new investment in rail transit is claimed to facilitate particular types of land use changes, mostly in the form of dense multi-family residential and mixed-use developments. Although rail’s effects on land use are widely claimed, scholarly evaluations offer mixed results. This paper examines two potential reasons for these mixed results. First, as most empirical examinations tend to be conducted shortly after new transit investment opens analysis is often criticized on the basis that short time frames may not allow land use changes to materialize. The second is that rail investment often includes changes to local zoning and land use regulations, creating opportunities for types of development that were previously outlawed. This paper evaluates these two critiques through an analysis of long-term land use effects associated with new rail transit service in San Diego, California. The results suggest that even after three decades of development cycles, rail transit has not led to consistent regulatory patterns of increased density or new mixed-use development.

Does mercury contamination reduce body condition of endangered California clapper rails?

International Nuclear Information System (INIS)

Ackerman, Joshua T.; Overton, Cory T.; Casazza, Michael L.; Takekawa, John Y.; Eagles-Smith, Collin A.; Keister, Robin A.; Herzog, Mark P.

2012-01-01

We examined mercury exposure in 133 endangered California clapper rails (Rallus longirostris obsoletus) within tidal marsh habitats of San Francisco Bay, California from 2006 to 2010. Mean total mercury concentrations were 0.56 μg/g ww in blood (range: 0.15–1.43), 9.87 μg/g fw in head feathers (3.37–22.0), 9.04 μg/g fw in breast feathers (3.68–20.2), and 0.57 μg/g fww in abandoned eggs (0.15–2.70). We recaptured 21 clapper rails and most had low within-individual variation in mercury. Differences in mercury concentrations were largely attributed to tidal marsh site, with some evidence for year and quadratic date effects. Mercury concentrations in feathers were correlated with blood, and slopes differed between sexes (R 2 = 0.58–0.76). Body condition was negatively related to mercury concentrations. Model averaged estimates indicated a potential decrease in body mass of 20–22 g (5–7%) over the observed range of mercury concentrations. Our results indicate the potential for detrimental effects of mercury contamination on endangered California clapper rails in tidal marsh habitats. - Highlights: ► We examined mercury in endangered California clapper rails within tidal marshes. ► Differences in mercury concentrations were largely attributed to tidal marsh site. ► Mercury concentrations in blood, feathers, and eggs were considered elevated. ► Body condition was negatively related to mercury concentrations. ► Results indicate detrimental effects of mercury on endangered clapper rails. - Mercury contamination in endangered California clapper rails was influenced by tidal marsh site and increased mercury resulted in reduced bird body condition.

Richmond, Orien Manu Wright

The secretive California Black Rail (Laterallus jamaicensis coturniculus ) has a disjunct and poorly understood distribution. After a new population was discovered in Yuba County in 1994, we conducted call playback surveys from 1994--2006 in the Sierra foothills and Sacramento Valley region to determine the distribution and residency of Black Rails, estimate densities, and obtain estimates of site occupancy and detection probability. We found Black Rails at 164 small, widely scattered marshes distributed along the lower western slopes of the Sierra Nevada foothills, from just northeast of Chico (Butte County) to Rocklin (Placer County). Marshes were surrounded by a matrix of unsuitable habitat, creating a patchy or metapopulation structure. We observed Black Rails nesting and present evidence that they are year-round residents. Assuming perfect detectability we estimated a lower-bound mean Black Rail density of 1.78 rails ha-1, and assuming a detection probability of 0.5 we estimated a mean density of 3.55 rails ha-1. We test if the presence of the larger Virginia Rail (Laterallus limicola) affects probabilities of detection or occupancy of the smaller California Black Rail in small freshwater marshes that range in size from 0.013-13.99 ha. We hypothesized that Black Rail occupancy should be lower in small marshes when Virginia Rails are present than when they are absent, because resources are presumably more limited and interference competition should increase. We found that Black Rail detection probability was unaffected by the detection of Virginia Rails, while, surprisingly, Black and Virginia Rail occupancy were positively associated even in small marshes. The average probability of Black Rail occupancy was higher when Virginia Rails were present (0.74 +/- 0.053) than when they were absent (0.36 +/- 0.069), and for both species occupancy increased with marsh size. We assessed the impact of winter (November-May) cattle grazing on occupancy of California Black

Demand forecast for rail shipment of radioactive material in the United States

A summary of the market potential for radioactive material (in millions of ton-miles) is presented in tabular form. These include the following: milled uranium ore; mill tailings; natural uranium hexafluoride; enriched uranium hexafluoride; fresh fuel, spent fuel; low-level waste; transuranic waste; and high-level waste. The maximum realistic market share for rail carriers is always less than these values because of the lack of rail access to some shipping and receiving facilities, small material quantities which could most easily move by other modes, short shipping distances for certain transport segments and greater operational convenience of other modes for some material categories. While market share and revenues for radioactive material are presently small, rail carriers appear to have a market advantage for milled uranium ore, transuranic waste and high-level waste. The potential for a significantly increased market share exists for spent fuel and uranium hexafluoride. While more fresh fuel and low-level waste can be transported by rail, it is unlikely that rail market share for radioactive materials (RAM) in general will rise to the potential maximum because many of these materials have historically been moved by truck and transported in frequent, small shipments

Simultaneous in-bore rail and insulator spectra from a railgun plasma armature

This paper reports on absolute spectral radiance measurements obtained simultaneously at the rail and insulator surface of the UTSI 1 cm square-bore railgun. The emission spectra were obtained through the use of quartz optical fibers which penetrated both the rail and the insulator walls. The spectral characteristics of the rail and insulator emission are quite similar but differ significantly in magnitude. A detailed plasma radiation model was used to analyze these spectra. In order to obtain reasonable agreement between the model predictions and the experimental spectra, it was necessary to assume that these existed a broadband absorbing layer at the insulator surface. This result suggests a new physical model of the plasma armature in which insulator ablation leads to significant 3-dimensional flow and affects the shape of the current emission pattern on the rail surfaces

The radiation mapping at various stations along Mumbai-Chatrapur rail route was carried out using GM, Plastic scintillator and NaI(Tl) based detectors. It has been observed that the average radiation level during the entire Mumbai-Chatrapur rail route was 63.8±6.l nSv h -1 and the maximum dose rate was 94.5±12.7 nSv h -1 and 103.2±10.2 nSv h -1 near Secunderabad and Chatrapur station respectively. The elevated radiation level at few locations was mainly due to the presence of terrestrial radiation i.e. naturally occurring radioactive material (NORM) viz., Thorium ( 232 Th) and Potassium ( 40 K) present in the environment. The spectral analysis led to confirming the presence of 232 Th and 40 K at the places. The main aim of the work was to generate the country wide baseline radiological data along selected important rail routes that could be used for radiological impact assessment. The results reported in this work would be helpful to provide valuable/useful reference data during the impact assessment at different locations

Full Text Available The article discusses the possibility of the application of the NFC technology as a system of selling tickets in passenger rail transport. The NFC (Near Field Communication technology is a wireless and contactless technology of transmission of radio data over short distances (max. 5 cm. This technology is very similar to the RFID (Radio Frequency Identification technology. It is assumed that this technology will spread rapidly and that already in 2015 around 85% of the payments in the EU will be made via mobile phones. This paper presents a research of passenger interest in this method of payment for tickets in the passenger rail transport in Slovakia. Further, an analysis of the applications of the NFC technology as a system of selling tickets in passenger rail transport, including the protection of data in mobile phones, the processes in case of losing a mobile phone and ensuring the communication between both parties was presented in the article. The last part of this analysis shows the possibility of purchasing tickets regardless of the carrier and the transport type.

The Diesel fuel injection equipment will remain a key element for Diesel engine technology evolution. Achieving emission targets at competitive prices has been and will continue to be a major technical challenge to the engine manufacturer. Delphi is continously developing its Common Rail System and its components for fulfill future stricter emission legislation while simultaneously improving performance on noise, fuel consumption and power output. The outstanding and unique injector concept combined with innovative control strategies has largely contributed to the improvement of exhaust emission and performance, consumption and NVH over the lifetime of Diesel vehicles. Recently, Euro 4 common rail applications have been introduced on several applications by adding further capability such as multiple injection, small-injected quantity control and improved atomization. This papers will describe the latest Common Rail System developments that Delphi will introduce into the market to comply with future legislative emission targets. Further, a novel common rail injector will be presented, that uses a revolutionary, direct acting operating principle, where the nozzle is directly operated by a piezo actuator, without the use of a servo-hydraulic flow circuit. The superior performance of this injector concept will be shown, especially with regard to it's near square rate injection shape, minimum quantity capability as well as multiple injection performance. The direct acting operating principle allows rapid opening and closing of the injector, without compromising pilot quantity capability. The emission benefit obtained by such opening and closing behavior will be shown. Finally, based on the findings discussed, the papers will conclude on key features of future common rail systems.

Highlights: • Comprehensive, nationwide risk assessment of hazardous material rail transportation. • Application of a novel environmental (i.e. soil and groundwater) consequence model. • Cleanup cost and total shipment distance are the most significant risk factors. • Annual risk varies from $20,000 to $560,000 for different products. • Provides information on the risk cost associated with specific product shipments. -- Abstract: An important aspect of railroad environmental risk management involves tank car transportation of hazardous materials. This paper describes a quantitative, environmental risk analysis of rail transportation of a group of light, non-aqueous-phase liquid (LNAPL) chemicals commonly transported by rail in North America. The Hazardous Materials Transportation Environmental Consequence Model (HMTECM) was used in conjunction with a geographic information system (GIS) analysis of environmental characteristics to develop probabilistic estimates of exposure to different spill scenarios along the North American rail network. The risk analysis incorporated the estimated clean-up cost developed using the HMTECM, route-specific probability distributions of soil type and depth to groundwater, annual traffic volume, railcar accident rate, and tank car safety features, to estimate the nationwide annual risk of transporting each product. The annual risk per car-mile (car-km) and per ton-mile (ton-km) was also calculated to enable comparison between chemicals and to provide information on the risk cost associated with shipments of these products. The analysis and the methodology provide a quantitative approach that will enable more effective management of the environmental risk of transporting hazardous materials.
