Abstract

Con la idea de que las prácticas cotidianas entre los inmigrantes mexicanos permiten construir y redefinir el espacio transnacional, como punto de partida, en este artículo se explorará la noción de la migración desde la perspectiva del transnacionalismo, en el marco de las tendencias contemporáneas del fenómeno migratorio en México. Al examinar las interacciones de los inmigrantes en el transporte público en San Diego, California, se buscará entender cómo se crean y recrean sus acciones. Este acercamiento desde un espacio social, permite analizar las interacciones específicas entre sociedades con historias y procesos de desarrollo diferentes. Based on the idea that everyday practices among Mexican immigrants allow the construction and redefinition of a transnational space, as a starting point, this article will explore the notion of migration from the perspective of transnationalism, within the framework of current tendencies in Mexican migration. Examining immigrant interactions in the public transportation system in San Diego, California, we will try to understand how they create and recreate their actions. This approach from a social space allows the analysis of the specific interactions between societies with different histories and development processe Document type: Article

Abstract

The geometry of converging-diverging nozzles affects the conditions at which critical-subcritical flow transition occurs. The objective of this work is to develop guidelines to identify the optimum nozzle geometry that maximizes critical pressure ratio while minimizing pressure drop across the nozzle. Experiments were conducted in a facility with 1.5 in. ID PVC pipelines and a 30 ft. long lateral pipeline section. In total, 27 different nozzle geometries were tested, divided into two groups – conical and parabolic nozzles. Nozzles from the ASTAR, Deich, LJ and Moby Dick nozzle groups showed improved performance compared to other nozzle groups. It was determined that a smaller diverging angle and absence of an elongated throat resulted in a higher critical pressure ratio. Length of converging and diverging sections of nozzles did not have as much of an impact on nozzle performance as the throat diameter and shape of converging and diverging sections.

Abstract

The main focus of the paper is on the container system development in the Baltic Sea Region studying cotemporary changes and organisation, as well as explaining the main driving forces of this situation. The Baltic Sea is a transport corridor between Eastern and Western Europe. Over the last decade maritime transport in the Baltic Sea area has changed significantly. The disintegration of the Soviet Union forced Russia to start developing its own Baltic ports and terminals and to find new routes to export its oil and gas. The Baltic ports have welcomed a remarkable growth, especially in oil transportation and containerised flows. The geographical configuration of the region naturally places it away from major global shipping lines. This situation is accentuated by the organisation of maritime regular lines, centred in Northern European ports. For this reason, the regional container network is mainly made up of feeder services.

Abstract

"jats:p"Smart City as a concept presupposes using new information and communication technologies in order to improve the quality of life within a particular geographic area. There are six different pillars in the frame of this concept and their one purpose is to achieve better efficiency of city operations. Smart mobility and transport are some of them. The efforts of traditional cities to become smart are not easily and quickly achievable. Numerous traffic solutions have already been implemented in different cities all over the world that make the ‘jump’ from traditional city to smart city. This paper provides an overview of the ‘smart’ transport solutions that have been implemented in the city of Skopje as a traditional city, which is on its way to becoming a smart city."/jats:p" "jats:p"The presented smart solutions are related to traffic management and control area and are aimed at alleviating traffic problems. The focus is on non-motorized solutions, e-vehicles, adaptive traffic control systems and public transport solutions. Several aims have been set in this paper – to promote the achievements of the municipality of Skopje aimed at transforming Skopje into a smart city in a transport area; to present its functionality, and to point out the disadvantages related to law regulations and the interconnection of all stakeholders involved. Finally, the idea is to provide a starting point for future research and to recommend future steps in this direction in the city of Skopje. Document type: Article

Abstract

Reported cases of traumatic brain injuries are increasing among the Canadian population. With an annual rate of 187,000 reported cases a year and growing, there is an extrapolated growth of 239,000 cases of traumatic brain injuries occurring annually by 2036. As Ontario intends to be a completely accessible province for those with disabilities by 2025, this paper utilizes GIS to visualize and better understand the relationship between post- TBI residents living in Brampton and their accessibility to public transportation. As Brampton is currently the most expensive city to insure a vehicle because of frequent collisions occurring within the city, creating a more accessible, reliable, and efficient public transportation system can integrate those who have experienced a traumatic brain injury back into society while reducing the required use of a personal vehicle. This will contribute to a safer city, as there are fewer vehicles on the road at risk of being involved in a road accident. There are also further benefits to this, as it will also reduce levels of congestion in the foreseeable future. info:eu-repo/semantics/publishedVersion Document type: Article
