Developing a framework for using structure-from-motion techniques for road distress applications

2020

On Urban road networks, road agencies need to quickly identify road pavement distresses in order to identify appropriate maintenance and rehabilitation strategies. This is integral as agencies are plagued with financial and time constraint issues. There have been several attempts over the last few years to identify new solutions and techniques to solve these issues. Several of these have shown merit and accuracy in identifying distresses. However, the techniques in many instances are not correlated to available distress identification standards. One of the considered techniques is the use of Structure-from-Motion, which tries to recreate 3D distress models for identification and analysis. T…

Microstructure and shear strength evolution of a lime-treated clay for use in road construction

2020

The results of a comprehensive experimental programme are presented for assessing the long-term microstructural modifications and evaluating the effects of microstructural rearrangement on the stress–strain behaviour of a lime-treated high-plasticity clay for road embankments. The stress–strain behaviour at different lime content and curing time was investigated by means of direct shear tests; microstructural analyses were carried out combining Scanning Electron Microscope observations and Mercury Intrusion Porosimetry tests. The results show that the stress–strain behaviour of treated clay is strongly dilatant with a high peak of strength, which increases with time and lime content. Furthe…

Driver stress in five Spanish-speaking countries: Construct validity of the LatinSET

2020

Abstract Introduction Driver stress is a phenomenon many have studied in probably all five continents. It has been the focus of curiosity for all sorts of disciplines, and science has been unable to curb it, much less park it. Objectives This study aims to generate a unique scale that can be used in Spanish speaking countries regardless of culture or geography. Method and Materials A sample of 1954 drivers from Mexico, Guatemala, Costa Rica, Chile and Spain was comprised. Through this study, the original 21 items of the ISET (Stressful Situations in Transit Inventory, in Spanish) were used to carry out both an Exploratory Factorial Analysis as well as a Confirmatory Factorial Analysis. Resu…

Modéliser le rôle des paysages dans les choix d'itinéraires pédestres

2008

Actuellement, la marche a pied suscite un regain d'interet comme mode de transport complementaire. Dans le cadre de cet article, nous partons de l'hypothese que l'adaptation de l'environnement urbain aux attentes des pietons, notamment d'un point de vue paysager, est une etape essentielle de la revalorisation de ce mode de deplacement. A cette fin, nous proposons une demarche permettant de decrire les comportements pedestres et d'identifier les preferences paysageres des pietons dans les villes de Besancon et de Lille. La methode d'analyse se fonde sur les modeles de choix discret, couramment utilises dans la modelisation des choix individuels. Celle-ci permet de mesurer, de maniere desagre…

Using UAV Based 3D Modelling to Provide Smart Monitoring of Road Pavement Conditions

2020

Road pavements need adequate maintenance to ensure that their conditions are kept in a good state throughout their lifespans. For this to be possible, authorities need efficient and effective databases in place, which have up to date and relevant road condition information. However, obtaining this information can be very difficult and costly and for smart city applications, it is vital. Currently, many authorities make maintenance decisions by assuming road conditions, which leads to poor maintenance plans and strategies. This study explores a pathway to obtain key information on a roadway utilizing drone imagery to replicate the roadway as a 3D model. The study validates this by using stru…

Indexing epistemic incongruence: uy as a formal sign of disagreement in agreement sequences in Spanish

2018

Abstract This study explores epistemic incongruence in Spanish by focusing on the particle uy in Iberian Spanish. It is claimed that this interjection has a basic change-of-state meaning and that it is commonly used to stress disagreement. Despite its general association to disagreement, the particle can be used in agreeing responses, where it also treats the previous turn as problematic. In this sequential environment, however, it is not the content of the previous turn but rather the underlying assumptions (the basic epistemic configuration of an assertion-answer adjacency pair) that are challenged by the second speaker. The evidence for this analysis comes from the sequential context. Ty…

The internally layered foot in Dutch

2017

AbstractRecent metrical studies have proposed that, under certain circumstances, a weak syllable may be adjoined to a binary foot, giving rise to a minimally recursive foot. Adding to a growing body of research from metrical stress and foot-conditioned phenomena in various languages, the goals of this paper are twofold. First, we aim at providing empirical evidence for internally layered feet based on the distribution of three foot-conditioned processes of Dutch: vowel reduction, glottal stop /ʔ/ insertion and /h/ licensing/deletion. Second, we explore a less studied theoretical and descriptive advantage of internally layered feet: their potential to predict phonological strength distinctio…

‘What’s the Moment Thingy?’– On the Emergence of Subject-Specific Knowledge in CLIL Classroom Interaction

2017

Situated in the European CLIL context where mainstream schools may opt for teaching content subjects through the medium of a foreign or second language, this paper explores secondary school physics classrooms, taught through English in Finland. The focus is on the role of classroom interaction in the emergence of subject-specific knowledge during six consecutive lessons, with particular attention to how one key concept in physics, ‘moment’, is handled. This micro-longitudinal approach shows that while the students are struggling between the everyday and the academic meanings of the word ‘moment’ throughout, there are also clear signs of progression. These signs show, for example, in student…

A Tool to Assess Architectural Education from the Sustainable Development Perspective and the Students' Viewpoint

2021

[EN] Architectural education plays a fundamental role in achieving sustainable development by training future professionals who can contribute to sustainability through their practice. Nevertheless, to ensure the introduction of sustainable development in the education of future architects, it is fundamental to understand what is being done and what could be improved. Despite this, a big gap has been detected in the assessment of architectural education in Spain and worldwide. Thus, a close-ended questionnaire for students has been designed based on the outcomes from a literature review, exploratory interviews with specialists, and the qualitative analysis of two schools of architecture. Ad…
