Abstract. Human self-localisation is an important part of everyday life. In order to determine one’s own position and orientation, the allocentric representation, usually in the form of a map, has to be aligned with one’s own egocentric representation of the real world. This requires objects (anchor points) that are present in both representations. We present two novel approaches that aim to simplify the process of alignment and thus the self-localisation. The Viewshed approach is based on visibility analysis and the Image Recognition approach identifies objects and highlights them on the map. On the basis of an empirical experiment with 30 participants in the city of Vienna, Austria, the two approaches were compared with each other as well as with a standard approach using a 2D map representation. The goal is to assess and compare aspects like efficiency, user experience, and cognitive workload. Results show that the Image Recognition method provided the best support and was also most popular among users. The Viewshed method performed well below expectations.

Self Potential

The main landfill in the city of Rabat (Morocco) is based on sandy material containing the shallow Mio-Pliocene aquifer. The presence of a pollution plume is likely, but its extent is not known. Measurements of spontaneous potential (SP) from the soil surface were cross-referenced with direct measurements of the water table and leachates (pH, redox potential, electrical conductivity) according to the available accesses, as well as with an analysis of the landscape and the water table flows. With a few precautions during data acquisition on this resistive terrain, the results made it possible to separate the electrokinetic (~30%) and electrochemical (~70%) components responsible for the range of potentials observed (70 mV). The plume is detected in the hydrogeological downstream of the discharge, but is captured by the natural drainage network and does not extend further under the hills.

Rgb Image

This paper proposes a new image segmentation algorithm to detect the flame image from video in enclosed compartment. In order to avoid the contamination of soot and water vapor, this method first employs the cubic root of four color channels to transform a RGB image to a pseudo-gray one. Then the latter is divided into many small stripes (child images) and OTSU is employed to perform child image segmentation. Lastly, these processed child images are reconstructed into a whole image. A computer program using OpenCV library is developed and the new method is compared with other commonly used methods such as edge detection and normal Otsu’s method. It is found that the new method has better performance in flame image recognition accuracy and can be used to obtain flame shape from experiment video with much noise.

The following investigation was realized with the objective to characterize the personal factors that influence in the development of resilience in 200 children aged between 7 and 12 years in families linked to the program Red UNIDOS in the city of Ibague, for this was applied the inventory of resiliency factors proposed by Salgado (2005), which evaluate the level of self-esteem, empathy, autonomy, humor and creativity. The results show that the sample is in the middle of the factors evaluated (61%) and that 69% did not face adequately the adversity. We conclude that adult significant training children require psycho-afective formation to enable them to generate environments based on the self awareness of their children. Is proposed to design a training program for parents to incorporate into their speeches and actions positive representations on their children, so that achieving self-assertive and enable them to develop the ability to overcome adversity.

The City

Ribeirão das Neves is a city in Minas Gerais with approximately 334 thousand inhabitants and 60% of the self-declared black population. In addition to the stigma “city of penitentiaries”, it was also known for the pun “Ribeirão das Trevas” published in the Official Gazette of the State on September 7, 2013 and on the website of the Court of Justice of Minas Gerais on August 21, 2018, and for thousands of publications of violence and poverty related by internet search algorithms. However, the city destined by the government to always be the same, houses other narratives created by a collective of black educating skaters: the Just Crew Skateboard. This article is an offshoot of the master's thesis and presents the results of the investigation, revealing in the light of the readings of Nilma Lino Gomes, how this group challenges the stigma of the city by showing new possibilities for engagement and a narrative that values life and sociability.
