In some cases, the processes of piercing or expanding pipe blanks involve the use of high-frequency active vibrations. However, due to insufficient knowledge, these processes are not widely used in the practice of seamless pipes production. In particular, the problems of increasing the efficiency of the processes of piercing or expanding a pipe blank at a piercing press using high-frequency vibrations are being solved without proper research and, as a rule, by experiments. The elaboration of modern technological processes for the production of seamless pipes using high-frequency vibrations is directly related to the choice of rational modes of metal deformation and the prediction resistance indicators of technological tools and the reliability of equipment operation. The creation of a mathematical model of the process of vibrating piercing (expansion) of an axisymmetric pipe blank at a piercing press of a pipe press facility is an actual task. A calculation scheme for the process of piercing a pipe plank has been elaborated. A dependence was obtained characterizing the speed of front of plastic deformation propagation on the speed of penetration of a vibrated axisymmetric mandrel into the pipe workpiece being pierced. The dynamic characteristics of the occurrence of wave phenomena in the metal being pierced under the influence of a vibrated tool have been determined, which significantly complements the previously known ideas about the stress-strain state of the metal in the deformation zone. The deformation fields in the zones of the disturbed region of the deformation zone were established, taking into account the high-frequency vibrations of the technological tool. It has been established that the choice of rational parameters (amplitude-frequency characteristics) of the vibration piercing process of a pipe blank results in significant increase in the efficiency of the process, the durability of the technological tool and the quality of the pierced blanks.

Taking into consideration the complexity of the new, heterogeneous, and different training needs currently present in the classrooms, the school is called to respond them in an effective and concrete way through inclusive educational approaches centered on the students, none excluded. On this basis, the authors, supporting the importance of technology in innovative teaching, propose the design and construction of an intelligent white stick through an inclusive cooperative methodology. The presented device, presented in this paper, is inspired by an open and collaborative teaching, enhancing a responsible digital education, accepting the training needs of all the students present in the classroom, specifically the blind student, and the recognition of the diversity in view of the reduction of disability.

Nowaday time indicator as hour and calendar constitutes necessary for thing a lot of person to trip routines. In general, the clock and the calendar can only be seen by normal people. People with special needs, its example is blind will have difficulty in using the clock and the calendar Get bearing with that problem, therefore to help that blind is designed and made by time indicator tool with voice output. Generally, the tool's instructions when using RTC DS1307, is microcontroller ATmega16 and ISD 25 120. Information about hour, minute, date, month, and year obtained from DS1307 RTC is accessed using microcontroller ATmega16, then from the data when the information obtained is matched in the voice storage unit on ISD25120. As a results,will be obtained time information data such as voice. Besides, time setting, alarm, battery level indicator, and charge the battery with the sound as well is the tool is equipped permanently. Finally, this tool can help the blind people to be more independent in making it easier to tell the time in living day-to-day activities.

Cultural Constructions

Changing ideas on the nature of and relationship between the senses in nineteenth-century Europe constructed blindness as a disability in often complex ways. The loss or absence of sight was disabling in this period, given vision’s celebrated status, and visually impaired people faced particular social and educational challenges as well as cultural stereotyping as poor, pitiable and intellectually impaired. However, the experience of blind people also came to challenge received ideas that the visual was the privileged mode of accessing information about the world, and contributed to an increasingly complex understanding of the tactile sense. In this chapter, we consider how changing theories of the senses helped shape competing narratives of identity for visually impaired people in the nineteenth century, opening up new possibilities for the embodied experience of blind people by impressing their sensory ability, rather than lack thereof. We focus on a theme that held particular social and cultural interest in nineteenth-century accounts of blindness: travel and geography.

The article deals with a two-channel queuing system with a Poisson incoming call flow, in which the application processing time on each of the devices is different. Such models are used, in particular, when describing the operation of the system for selecting service requests in a number of operating systems. A complex system characteristic was introduced at the time of service endings on at least one of the devices, including the queue length, the remaining service time on the occupied device, and the time since the beginning of the current period of employment. This characteristic determines the state of the system at any time. Recurrence relations are obtained that connect this characteristic with its marginal values when there is no queue in the system. The method of introducing additional events was chosen as one of the main methods for analyzing the model. The relationships presented in this article can be used for analysis of the average characteristics of this system, as well as in the process of its simulation. Summarizing the results of work on multichannel systems with an arbitrary number of servicing devices will significantly reduce the time required for simulating complex systems described by sets of multichannel queuing systems.

Este artículo es producto de una investigación que tiene como finalidad establecer la relación que tienen las TIC con el rendimiento académico de los estudiantes del Colegio Técnico Industrial “La Alborada” de la ciudad de Milagro, provincia del Guayas, Ecuador. Este estudio se enmarca dentro de las investigaciones descriptivas, correlacionales, ya que por medio del análisis, observación, comparación y descripción de las variables, se establece el escaso uso de las herramientas tecnológicas en el proceso educativo. Los datos estadísticos se obtienen de los resultados por la aplicación de instrumentos a los estudiantes y docentes de la institución. Se utilizaron los métodos deductivos, inductivos y teóricos para el desarrollo del proceso. La propuesta requiere un fortalecimiento en el uso de las nuevas tecnologías de la Información y Comunicación, siendo importante que los docentes conozcan el uso adecuado de las mismas y las integren en sus horas de clases, porque mejorará el rendimiento académico de los estudiantes por su nueva forma de explicar las clases que serán más interactivas y divertidas. Es necesario realizar un Plan de capacitación en el uso de las herramientas e- learning que garantice una educación de calidad.   Palabras claves: TIC, rendimiento académico, proceso educativo.   ABSTRACT   This article is the result of a research that aims to establish the relationship of ICTs to academic performance of students in the Industrial Technical College “La Alborada” in Milagro, Guayas, Ecuador. This study is part of a descriptive, correlational research, since through analysis, observation, comparison and description of the variables, the limited use of technological tool sin the educational process is established. The statistics are obtained from the resultsof the application of tools for students and teachers of the institution. Deductive, inductive and theoretical process development methods were used. The proposal requires as treng then ing in the use of new information and communication technologies and it is important that teachers become aware of their proper use and incorporate them in their classes, because these will improve the academic performance of students in classes that are more interactive and fun. It’s necessary to design a training plan in the use ofe-learning tools to ensure quality education.   Keywords: TIC, academic achievement, educational process.   Recibido: febrero 2015Aprobado: mayo 2015
