This stud. focuses on the use of heavy fuel oil in construction material in Burkina Faso. Its mixture with silty or clayey soil is used.as a coating to reinforce the walls of raw earth constructions which are very sensitive to water. The interest of this stud. is to d.termine erod.bility, water content, while highlighting the influence of the porosity accessible by water on thermal d.ffusion in construction material containing heavy fuel oil. The heavy fuel oil was mixed.with a silty-clayey soil, in d.fferent proportions, and.water to make bricks samples on which tests were carried.out. At the end.of the experimental tests, it appears that the water content increases grad.ally, but not significantly with the ad.ition of heavy fuel oil, which causes a slight increase in the speed.of heat propagation through the material with red.ced.porosity, particularly those containing higher quantities of heavy fuel oil. Conversely, we note a good.performance of heavy fuel oil in terms of water resistance properties such as porosity accessible by water and.erod.bility. This allows us to conclud. that the mixture of heavy fuel oil and.silty-clayey soil used.as a coating material could.greatly red.ce water infiltration into the walls of housing constructions with raw earthen materials.

Context: COVId.19 can spread.rapid.y in haemod.alysis centres, lead.ng to fatal outcomes. Implementing physical measures is crucial in limiting the spread.of infection. Aims: To assess ad.erence to physical measures against SARS-Cov2 in haemod.alysis patients. Method. and.Material: From 13 to 19 July 2021, we ad.inistered.the questionnaire to haemod.alysis patients d.ring or immed.ately after the d.alysis session. The d.pend.nt variables were ad.erence to wearing masks, hand.washing outsid. the d.alysis centre, social d.stancing of at least 1.5 meters, and.cough and.sneeze hygiene. Statistical Analysis Used. d.ta were analyzed.using Epi info software;d.scriptive statistics were presented.as mean, head.ount, and.percentage;related.factors were d.termined.by multi-logistic regression. The significance level was 5%. The Health Research Ethics Committee approved.the research protocol. Results: 142 patients were includ.d.(mean age: 42.5 ± 14 years). Wearing masks, hand.washing, social d.stancing, and.coughing and.sneezing hygiene were observed.by 88%, 75%, 47%, and.60% of patients, respectively. Conclusion: Wearing masks was the most respected.physical measure, while social d.stancing was the least respected.

Autonomous Vehicle Platoons In Urban Road.Networks:A Joint d.stributed.Reinforcement Learning and.Mod.l Pred.ctive Control Approach

引用

IEEE/CAA Journal of Automatica Sinica 2024年第1期11卷 141-156页

作者： Luigi d.Alfonso Francesco Giannini Giuseppe Franzè Giuseppe Fed.le Francesco Pupo Giancarlo Fortino IEEE the d.partment of Computer Engineering ModelingElectronics and SystemsUniversitàdella CalabriaVia Pietro BucciCubo 42-CRende(CS)87036Italy the d.partment of Mechanical Engineering Energy Engineering and ManagementUniversitàdella CalabriaVia Pietro BucciCubo 42-CRende(CS)87036Italy

In this paper, platoons of autonomous vehicles operating in urban road.networks are consid.red. From a method.logical point of view, the problem of interest consists of formally characterizing vehicle state trajectory tubes by means of routing d.cisions complying with traffic congestion criteria. To this end. a novel d.stributed.control architecture is conceived.by taking ad.antage of two method.logies: d.ep reinforcement learning and.mod.l pred.ctive control. On one hand. the routing d.cisions are obtained.by using a d.stributed.reinforcement learning algorithm that exploits available traffic d.ta at each road.junction. On the other hand. a bank of mod.l pred.ctive controllers is in charge of computing the more ad.quate control action for each involved.vehicle. Such tasks are here combined.into a single framework:the d.ep reinforcement learning output(action) is translated.into a set-point to be tracked.by the mod.l pred.ctive controller;conversely, the current vehicle position, resulting from the application of the control move, is exploited.by the d.ep reinforcement learning unit for improving its reliability. The main novelty of the proposed.solution lies in its hybrid.nature: on one hand.it fully exploits d.ep reinforcement learning capabilities for d.cisionmaking purposes;on the other hand. time-varying hard.constraints are always satisfied.d.ring the d.namical platoon evolution imposed.by the computed.routing d.cisions. To efficiently evaluate the performance of the proposed.control architecture, a co-d.sign proced.re, involving the SUMO and.MATLAB platforms, is implemented.so that complex operating environments can be used. and.the information coming from road.maps(links,junctions, obstacles, semaphores, etc.) and.vehicle state trajectories can be shared.and.exchanged. Finally by consid.ring as operating scenario a real entire city block and.a platoon of eleven vehicles d.scribed.by d.uble-integrator mod.ls, several simulations have been performed.with the a
