Bio materials with reclaimed asphalt: from lab mixes properties to non-damaged full scale monitoring and mechanical simulation
2019
Three innovative environmentally friendly pavement materials, designed with 50% of Reclaimed Asphalt and three different biomaterials (2 bio-additivated bitumens and 1 bio-binder), were produced in an industrial plant. These mixes were tested in lab and also at full scale using an Accelerated Pavement Test facility. The asphalt mix viscoelastic properties were measured in lab and their intrinsic viscoelastic response were simulated. These rheological models are used to simulate the pavement mechanical response using both elastic and viscoelastic multilayer codes. Hence, full scale measurement performed during the full scale test at an early stage (without damages) can be compared with these…
Response spectrum analysis of frame structures: reliability-based comparison between complete quadratic combination and damping-adjusted combination
2019
In the framework of seismic design of structures, response spectrum analysis (RSA) is the most commonly used approach in practice. The most popular combination rule is the complete quadratic combination (CQC) which is also prescribed by the most of seismic design codes and is based on the assumptions that the seismic acceleration is a white noise process and the peak factor ratios associated to the total and modal responses are unitary. Recently, the damping adjusted combination (DAC) rule has been developed for base-isolated structures to overcome the aforementioned simplified assumptions. Although it has been proved that the simplifications about peak factors lead to noticeable errors in …
From Nowhere to Everywhere
2017
International audience; This paper presents a synthetic view of a variety of projects built upon an Erasmuss Mundus Master Course. It highlights double degree programs, European credits transfer, joint PhDs, research collaborations as well as few other related European projects going from Thematic Networks to another Erasmus Mundus Course.
Boosting the performance of a Reverse Electrodialysis – Multi-Effect Distillation Heat Engine by novel solutions and operating conditions
2019
Abstract This work presents a performance analysis of a waste-heat-to-power Reverse Electrodialysis Heat Engine (RED-HE) with a Multi-Effect Distillation (MED) unit as the regeneration stage. The performance of the system is comparatively evaluated using two different salts, sodium chloride and potassium acetate, and investigating the impact of different working solutions concentration and temperature in the RED unit. For both salt solutions, the impact of membrane properties on the system efficiency is analysed by considering reference ionic exchange membranes and high-performing membranes. Detailed mathematical models for the RED and MED units have been used to predict the thermal efficie…
Astana's architecture as a representation of the new Kazakhstan : political reading of Astana's built environment
2015
In my Master’s thesis I explore the political reasons behind Kazakhstan’s Almaty Astana capital relocation and the creation of the new capital Astana with new and futuristic architecture. The strategy is to analyse Kazakhstan’s capital relocation and Astana’s creation and beautification by applying Kenneth Burke’s concepts of the Dramatistic Pentad and the Idea of the Negative. Through Astana’s three most prominent new pieces of architecture, the Baiterek Tower, the Palace of Peace and Reconciliation and Khan Shatyr shopping and entertainment centre, I analyse Kazakhstan’s political aspirations and new representational practises. Through Astana’s architecture and Burke’s Dramatistic Pentad …
Membrane Bioreactors for wastewater reuse: Respirometric assessment of biomass activity during a two year survey
2018
Abstract Stricter effluent limits, water shortage conditions, land availability requires today even more the needs of advanced wastewater treatments. Attractive solutions come from membrane bioreactors (MBR), Integrated Fixed Film Activated Sludge (IFAS) or combinations (i.e., IFAS-MBRs). One crucial aspect for the applicability of this overall new technology, compared to the conventional activated sludge systems, is the lack of knowledge for design and manage (e.g., kinetic constants, optimal operative conditions etc.). In view of the above frame, the aim of the present study was to assess the kinetic and stoichiometric parameters of bacterial species in MBRs by means of respirometric tech…
Evaluación de la investigación sobre la pedagogía Construcción de Conocimiento: un enfoque metodológico mixto
2020
Knowledge Building (KB) is a theoretical framework that promotes collective inquiry through the resolution of knowledge problems that are relevant for certain educational community. There is an increasing number of authors looking into benefits of this approach, thus an overview of the trends of research is needed. The aim of this study is to provide the state of the art concerning the research production on Knowledge Building pedagogy including trends and relevant issues. In this study a sequential explanatory design was applied. Both quantitative (scientometric analysis) and qualitative (systematic review) approaches were applied. The sample was selected from the most recent productions p…
SEMANTIC MANAGEMENT OF INTELLIGENT MULTI-AGENTS SYSTEMS IN A 3D ENVIRONMENT
2011
8 pages; International audience; This paper presents a new approach combining the 3D elements composing the environment of mobile agents with semantic descriptors from Building Information Models. Our proposal is based on the IFC standard, which is used in the field of Civil Engineering to build digital models of buildings during the design phase. The semantic of IFC objects composing the 3D environment is used to select and set up 3D objects and elements of simulation scenarios. The result of this process dynamically generates the input files for the JaSIM environment that performs the simulation. These files deserve the representation of the virtual environment in which the simulation is …
Ontological Analysis of the Project Risk Management Concept ‘Risk’
2018
Abstract The aim of the current research series is to examine the definitions of the concept ‘risk’ and analyze the concepts used in the definitions of ‘risk’ in the sources of these definitions in order to perform the ontological analysis of the concept of ‘risk’. Ontological and epistemological analysis of the concepts in the definition of the concept ‘risk’ was used to answer the question what ‘risk’ means in project management. This investigation represents a part of the research series where the ontological, epistemological and methodological analysis of project risk is performed with the aim to improve risk registers and risk management as a whole. In the previous studies the author a…
From common operational picture to common situational understanding: An analysis based on practitioner perspectives
2021
Abstract The concepts of Situational Awareness (SA) and Common Operational Picture (COP) are closely related and well-acknowledged to be crucial factors for effective emergency management. In multi-agency operations, such as extreme weather events, the involved first responders manage the event with different mandates, objectives, and tools which can make it challenging to build a COP. Effective collaboration requires a common situational understanding, based on knowledge about each other’s responsibilities and tasks, mutual respect and trust, as well as common communication tools for emergency communication and information sharing. This paper argues that the COP serves as a basis for decid…
