Wear and fatigue in rails are major contributors of rail degradation depending on operational conditions, track, characteristics of bogie type, Million Gross Tonnes (MGT), curvature, traffic type and environmental conditions. Estimation of parameter for failure models is necessary for accurate prediction of expected number of rail defects over a period of time based on MGT of traffic and operat...

Classical model SDcl of the Dirac particle SD is constructed. SD is the dynamic system described by the Dirac equation. For investigation of SD and construction of SDcl one uses a new dynamic method: dynamic disquantization. This relativistic purely dynamic procedure does not use principles of quantum mechanics. The obtained classical analog SDcl is described by a system of ordinary differentia...

Forest fires are a major risk factor with strong impact at eco-environmental and socioeconomical levels, reasons why their study and modeling are very important. However, the models frequently have a certain level of uncertainty in some input parameters given that they must be approximated or estimated, as a consequence of diverse difficulties to accurately measure the conditions of the phenome...

Abstract The current climate service creation practice misses clear provider–user collaborations, and this presents a challenge for the educational design of capacity-building programs. This study analyses formation principles in six training courses aimed at tailored services. are analyzed using constructive alignment three curriculum perspectives as analytical frameworks. Three main issues we...

evaluation of the advantages and weaknesses of principles oftransnational civil procedure, the joint work of the institute of americanlaw and the institute of unification of private law is the main subject ofthis article. the innovations of these principles such as the cooperationtheory, the distinction between the “principles” and the “rules”, thereasonable speed in addressing the case, provid...

There are a number of requirements by which animals should be managed so that the best performance is achieved in a way acceptable to those responsible for the care of the animals and to the community generally. These requirements are the keys to good management and may be used to test the management of a poultry enterprise in relation to the standard of its management. These requirements are a...

after the teacher, the most important factor in foreign language classroom is the textbook. it is vital that the best possible text be chosen for each situation. even with the development of new technologies that allow for higher quality teacher-generated materials, demand for textbooks continues to grow, and the publishing industry responds with new series and textbooks each year. therefore, i...

This article examines the requirements for quality learning, that is based exclusively on nadzom “alālā” wrote by Burhān al-Dīn al-Nu’mān ibn Ibrōhīm al-Zarnūjī in his treatise entitled “Ta’līm al-Muta’allim Ṭorīq al-Ta’allum”. The quantitative research descriptive studies category used this and results are described content analysis technique. It reveals learning has six things dependency: ing...

Engineering educators often create slides for classroom presentations to instruct students. In turn, engineering students often create slides for classroompresentations to demonstratewhat they have learned.Given howoften presentation slides are projected and viewed by engineering educators and students, those slides should follow principles of multimedia learning to foster high audience compreh...
