Chloride-induced corrosion has been one of the main causes reinforced concrete deterioration. One most used methods in assessing chloride penetration resistance is rapid migration test (RCMT). This an expeditious and simple method but may not be representative transport behaviour real environment. Other methods, like immersion (IT) wetting–drying tests (WDT), allow for a more accurate approach to reality, are laborious very time-consuming. paper aims analyse capacity RCMT common produced...

Abstract The effort towards a greener future will entail shift to more environmentally friendly alternatives of many human activities. Within this context, the path decarbonized society in general, and industrial decarbonization particular, require using low carbon solutions and/or capturing emissions at source. This flux captured then management one option is store it concrete. incorporation CO2 can be done during mixing curing. While latter efficient effective terms amount incorporated,...

Carbon capture storage and utilization is the main technology for reducing CO2 emissions, accounting 56% of overall reduction required to achieve carbon neutrality concrete by 2050. Different strategies have been explored in cement-based materials towards this end, namely, concrete. However, impact on carbonated differs depending moment at which cementitious material comes into contact with CO2, either terms uptake or its lifetime performance. This paper presents three leading that rely...

There is a growing demand for new forms of intercultural training. We describe demonstration an agent-based application designed to teach young adults (18-25) general patterns behaviour that can distinguish broad range cultures. Training done through interactive-story telling approach where the user must go series critical incidents, interacting with agents capable simulating different synthetic cultures in their behaviour.

Cement paste powder (CPP) is a by-product of the recycling process concrete with an elevated carbonation capability and potential to be recycled as binding material in new batches. The application treatment CPP improves this even more, besides evident gains terms CO2 net balance. However, long duration usually adopted treatment, from 3 28 days, hampers industrial viability process. We studied feasibility short-duration process, two hours, carrying out comprehensive characterization...

Abstract Adaptive middleware is essential for developing distributed systems in several applications domains. The design and implementation of this kind middleware, however, it still a challenge due to general adaptation issues, such as When adapt? Where include the code? What adapt?, How guarantee safe adaptations?. Current solutions commonly face these challenges at level do not focus on safety aspects adaptation. This paper proposes holistic solution implemented Go programming language...

Rosmarinic acid (RA) is a phenolic compound with biological activity. The objective of the present study was to investigate whether this kept its activity in presence proteins. For purpose, bovine serum albumin (BSA) used as model protein, and capacity RA inhibit acetylcholinesterase (AChE) affect antioxidant evaluated absence BSA. A mixture compounds containing RA, obtained from medicinal plant added study. AChE inhibitory reduced by ∼57% BSA, while increased. These results lead...

The estimation of the intrinsic properties an unknown object is a very challenging problem, mainly due limitations on tactile technology. In this article we present method to estimate object's weight during precision grip made by humanoid robot. Tactile sensors fingertips provide information 3D force vector movement grasping and lifting cup filled with different masses (30-100g). Using measurements across time, were able successfully calculate for 8 masses, repeatable measurement low...

The recycling process of concrete originates a byproduct, cement paste powder (CPP), which is material composed mainly hydrated cement. This cementitious has demonstrated promising results when applied as binder in new batches, provided it been subjected to previous carbonation process. One the obstacles industrial application this strategy long duration typical process, requires from 3 28 days. Recently, authors have developed short two-hour and thoroughly analysed over its entire...

Abstract Optimal well placement seeks to achieve two seemingly contradictory objectives. For the short term, needs establish longest possible contact with productive zone in order enhance early production. long term production strategy of field, challenge is maximize total volume hydrocarbon produced during life field. The first objective can be readily achieved by staying away from all reservoir boundaries at times; this includes oil-water and cap rock for an oil reservoir. second requires,...

In order to secure wireless communications, we consider the usage of physical-layer security (PLS) mechanisms (i.e. coding for secrecy mechanisms) combined with self-interference generation. We present a prototype implementation scrambled mechanism interference generation by legitimate receiver and cancellation effect (SI). Regarding SI cancellation, two algorithms were evaluated: least mean square recursive squares. The is performed in real-world software-defined radio (SDR) devices using GNU-Radio.

The concrete sector is known for its significant contribution to CO2 emissions. There are two main contributing factors in this situation: the large amount of consumed per year on planet and high levels released from manufacture Portland cement, key binding agent concrete. To face consequent sustainability issues, diverse strategies involving carbon capture storage potential cementitious materials have been explored. This paper addresses storing during curing stage within context precast...

Abstract Carbonate reservoirs evaluation is challenging from different aspects related to stratigraphic and structural features heterogeneities. One of the major challenges fractures in terms nature, intensity, aperture extension. Near far field techniques had been utilized achieve advanced modeling. This later a key factor for successful carbonate reservoir development. Resistivity images cores help quantitative analysis near wellbore intensity aperture; high resolution seismic data can...

Abstract The energy crisis and climate change have promoted a growing interest in non-fossil sources, such as nuclear, with uranium carbides being seen potential fuel candidates for Generation IV nuclear reactors. However, the need of accurate thermophysical data its compatibility core materials during extreme fission conditions is still an issue. Here study ternary uranium-iron-carbon system performed at 1100 °C using powder x-ray diffraction Scanning Electron Microscopy coupled Energy...
