[more ▼] Gravel wash mud (GWM), a waste product from gravel mining was dried and processed into a fine powder to be activated by different concentrations of sodium hydroxide (NaOH) solutions for the synthesis of an alkali-activated binder. The GWM powders were thermally treated at five different calcination temperatures 550, 650, 750, 850 and 950°C. The characterisation of the raw material comprises the particle size distribution (PSD) by laser granulometry, the chemical and mineralogical composition by X-ray fluorescence and X-ray diffraction analysis respectively, and simultaneous thermal analysis. The performance of the alkali-activated binders was examined using compression strength tests and the microstructure was observed using scanning electron microscopy (SEM). The GWM was classified as an aluminosilicate raw material with kaolinite and illite as main clay minerals. Furthermore, a mean particle size around 6.50μm was determined for the uncalcined and calcined GWM powders. The SEM images of the developed binders showed the formation of a compact microstructure, however, relatively low strengths were achieved. This preliminary study highlights an example of an aluminosilicate prime material, which shows very promising chemical and mineralogical characteristics, but its suitability for alkaline activation without further additives was not confirmed as far as performance-based criteria are considered.

[more ▼] In the present paper, a model-based fault/attack tolerant scheme is proposed to deal with cyber-threats on Cyber Physicals Systems. A common scheme based on observers is designed and a state feedback control based on an event-triggered framework is given with control synthesis and condition on the switching time. An event-based implementation is proposed in order to achieve novel security strategy. Observer and controller gains are deduced by solving su cient Bilinear Matrix Inequality (BMI) condition. Simulation results on a real-time laboratory three tank system are given to show the attack-tolerant control ability despite data deception attacks on both actuators and sensors.

[more ▼] A decoupling approach for state estimation of nonlinear systems represented in the polytopic Takagi-Sugeno with unmeasurable premise variables subject to unknown inputs is proposed in this paper. The idea consists in defining a state and unknown input transformations in order to divide the state vector into two parts, a measurable part and an observable one (decoupled from the unknown input). A classical Luenberger observer to estimate the unmeasurable part is then designed and given in terms of Linear Matrix Inequalities (LMIs) conditions. A numerical example is also presented in order to illustrate the proposed approach.

[more ▼] In the present paper, the problem of networked control system (NCS) cyber security is considered. The geometric approach is used to evaluate the security and vulnerability level of the controlled system. The proposed results are about the so-called false data injection attacks and show how imperfectly known disturbances can be used to perform undetectable, or at least stealthy, attacks that can make the NCS vulnerable to attacks from malicious outsiders. A numerical example is given to illustrate the approach.

[more ▼] ORBIT implements and studies a joint problem-solving activity at an interactive tabletop providing participants with the opportunity to develop their collaboration methods by jointly overcoming breakdowns. The design and the research process relies on user-centered design methods and on an ethnomethodological conversation analytic framework. The project will generate scientific knowledge on participants’ collaboration methods and create a powerful collaborative learning tool.

[more ▼] As Prime Minister and Finance Minister of Luxembourg over several decades, Pierre Werner shaped the future of his country and was one of the rare statesmen to play a part in the progress of European integration until the mid-1980s. He played a major role in regional integration (BLEU, Benelux) and in EEC policy-making and gained a strong reputation for forging a political consensus between larger powers (Germany and France)and between diametrically opposed positions (‘economists’ vs ‘monetarists’). In this way he succeeded in defending Luxembourg’s vital interests, from the financial centre to the seats of the European institutions. Werner was involved in the major ideological debates of the time. Although initially in favour of a monetary approach, Werner was one of the first to develop arguments for a symmetrical economic and monetary union.

[more ▼] Ce texte receille des notes de lecture critiques relatives à l'analyse interdisciplinaire réalisée par Michel Aglietta et Nicolas Lerron dans leur ouvrage « La double démocratie. Une Europe politique pour la croissance », récemment publié aux Éditions du Seuil. Les auteurs placent leur analyse dans une perspective historique, avec l’objectif d’expliquer pourquoi l’Europe est plus vulnérable que les autres région du monde et d’identifier les moyens de donner de nouvelles impulsions au projet européen. Le constat des auteurs est sans appel : l’Union européenne et la zone euro sont aujourd’hui en impasse. Parmi les principales causes, ils identifient l’impuissance publique, les interdépendances négatives entre les États membres et le caractère incomplet de l’UEM. Ils mettent également en lumière une crise de la méthode de l’intégration européenne, vu que le postulat de l’engrenage, ou encore celui des petits pas prôné par Jean Monnet semblent avoir épuisé toutes leurs potentialités.

[more ▼] We present a precoded multi-user communication test-bed to demonstrate forward link interference mitigation techniques in a multi-beam satellite system scenario, which will enable a full frequency reuse scheme. The developed test-bed provides an end-to-end precoding demonstration, which includes a transmitter, a multi-beam satellite channel emulator and user receivers. Each of these parts can be reconfigured accordingly to the desired test scenario. Precoded communications allow full frequency reuse in multiple-input multiple-output (MIMO) channel environments, where several coordinated antennas simultaneously transmit to a number of independent receivers. The developed real-time transmission test-bed assist in demonstrating, designing and benchmarking of the new Symbol-Level Precoding (SLP) techniques, where the data information is used, along with the channel state information, in order to exploit the multi-user interference and transform it into the useful power at the receiver side. The demonstrated SLP technique is designed in order to be computationally efficient, and can be generalized to others multi-channel interference scenarios.

[more ▼] Manufacturing scheduling strategies have historically ignored the availability of the machines. The more realistic the schedule, more accurate the calculations and predictions. Availability of machines will play a crucial role in the Industry 4.0 smart factories. In this paper, a mixed integer linear programming model (MILP) and a discrete firefly algorithm (DFA) are proposed for an extended multi-objective FJSP with availability constraints (FJSP-FCR). Several standard instances of FJSP have been used to evaluate the performance of the model and the algorithm. New FJSP-FCR instances are provided. Comparisons among the proposed methods and other state-of-the-art reported algorithms are also presented. Alongside the proposed MILP model, a Genetic Algorithm is implemented for the experiments with the DFA. Extensive investigations are conducted to test the performance of the proposed model and the DFA. The comparisons between DFA and other recently published algorithms shows that it is a feasible approach for the stated problem.
