Génétique textuelle : approches croisées et études de cas
2023
"Génétique textuelle : approches croisées et études de cas" confronte, sur des oeuvres diverses, les acquis de la critique génétique telle qu'elle s'est développée et enrichie particulièrement en France depuis sa fondation d'obédience structuraliste et à distance des analyses issues de la tradition philologique italienne dans le fil de la « critique des variantes ». D'autre part, les différents articles offrent, à côté de corpus manuscrits déjà bien étudiés tels que Flaubert et Proust, des investigations sur des auteurs qui ne sont que rarement analysés dans le cadre d'études de genèse, qu'il s'agisse de Butor - dont on présente ici des manuscrits inédits - Némirovsky, Malraux ou Pavese.
Analytical approach for the mix design optimisation of bituminous mixtures with crumb rubber
2018
The present paper provides a basis for defining a mix design method specifically tailored to rubberised asphalt that takes into account the behaviour of crumb rubber. An analytical approach to quantifying the recovered deformation of crumb rubber in the post-compaction phase has been developed in order to adjust the number of gyrations proposed by the Superpave method for compacting specimens of hot mix asphalt using a Superpave gyratory compactor. The maximum allowable amount of rubber has been calculated. Finally, a step-by-step protocol has been proposed in order to fabricate and compact crumb rubber modified mixtures with the gyratory compactor.
Increased Stability of Rubber-Modified Asphalt Mixtures to Swelling, Expansion and Rebound Effect during Post-Compaction
2017
The application of bituminous mixtures modified with rubber from scrap-tires require attention and care during mixing and compaction. Rubber modifies the properties because it reacts in the internal structure of bitumen at high temperatures changing the performance of the mixture (interaction process of solvents with binder-rubber aggregate). The main change is the increasing of the viscosity and elasticity of the binder due to the larger sizes of the rubber particles by dry process but, this positive effect is counteracted by short mixing times, compared to wet technology, and due to the transport processes, curing time and post-compaction of the mixtures. Therefore, negative effects as sw…
Cesare Pavese’s Il campo di granturco: geographical trails
2021
This article proposes a critical reading of the short story, Il campo di granturco [The Cornfield], by Cesare Pavese. Methodologically and epistemologically, it tries to highlight the existing consonances between literature and geography with regards to three key concepts – the border, the landscape, and the territory – that form an indissoluble connection between human beings and the world. In geography, border, landscape, and territory are regarded as key cognitive mediators within the interaction between the Self and the world. What purpose, then, does reading Pavese from a geographic perspective serve? Why do his works matter within the context of cultural geography? Pavese’s Il campo …
Towards Low-Cost Pavement Condition Health Monitoring and Analysis Using Deep Learning
2020
Governments are faced with countless challenges to maintain conditions of road networks. This is due to financial and physical resource deficiencies of road authorities. Therefore, low-cost automated systems are sought after to alleviate these issues and deliver adequate road conditions for citizens. There have been several attempts at creating such systems and integrating them within Pavement management systems. This paper utilizes replicable deep learning techniques to carry out hotspot analyses on urban road networks highlighting important pavement distress types and associated severities. Following this, analyses were performed illustrating how the hotspot analysis can be carried out to…
Monitoring road pavement performance through a novel data processing approach, accelerated pavement test results
2020
This research presents a novel performance-based interpretation method for continuous monitoring of pavement condition through the use of piezoelectric sensors. The objective of this study is to validate the compressed cumulative loading event approach, implemented in a previously developed piezoelectric sensor, for detecting subsurface fatigue cracking through full-scale accelerated pavement testing. A piezo-electric film of polyvinylidene fluoride is used to harvest the microstrain energy induced by the traffic loading at the surface. Epoxy is used to protect the sensor following a H-shape packaging. Piezoelectric sensors were exposed to approximately 1.0 million load repetitions between …
OpenGL kodola kolapsa vizualizācija
2021
Bakalaura darbs tiek fokusēts uz zinātnisku simulāciju atveidošanu OpenGL grafiskajā vidē. Darbā tiek apskatītas konstrukcijas, metodes un optimizācijas pasākumi, lai vizualizētu pirmszvaigzņu mākoņa saraušanos. Tiek arī dots ieskats montekarlo metodē, lineārā interpolācijā un kubisku splainu interpolācijā. Darba gaitā ir izveidotas divas programmas, simulācijas vizualizācija un vērtību ģenerēšana izmantojot interpolācijas un integrācijas bibliotēku. Programmām ir apskatīta arī veiktspēja un izpildes laiks.

SUP R DSS: A sustainability-based decision support & system for road pavements
2019
Road pavement community members are increasingly becoming aware of the need to incorporating the principles of sustainable development into the sector. Policies are also going in this direction and as a consequence in the recent years researchers and practitioners are coming up with new materials, technologies and practices designed to reduce the negative impacts of their activities in the surroundings. Within this framework the road pavements sector is witnessing a paradigm shift towards the development of pavement technologies incorporating high-content of recycled materials, as well as best practices to decrease the overall carbon footprint. These are all promising solutions that to the …
Design considerations of high RAP-content asphalt produced at reduced temperatures
2018
In many countries recycling of reclaimed asphalt pavement (RAP) for road surface layers is limited to a maximum of 10–30%. This is due to technical limitation of common asphalt plant but also to specifications that are still restrictive when it comes to increasing RAP in surface courses. The mistrust in this practice is mainly related to uncertainty in performance of these mixes as well as to existing fundamental issues with the mix design, especially when production temperatures are lowered. This paper analyses some of the factors affecting the design of warm asphalt mixtures for surface course layers containing 50% RAP, and suggests a framework to justify the common assumption of full ble…
