abstract = {The objective of this research was to evaluate the feasibility of producing structural lightweight concrete prestressed girders with load-bearing capacities similar to conventional concrete girders. The methodology consisted of comparing the results of the production and monitoring of scaled prestressed concrete beams at a precasting plant and the subsequent flexural testing. The beams were produced using two types of lightweight concrete and a conventional reference concrete with similar compressive strengths to allow for a comparison of the structural performance of the beams. The goal was to estimate an upper bound for the development length of fully developed prestressing strands with a diameter of 15.2. mm (0.6″). The load-bearing capacity and ductility of the beams were determined by flexural tests. All lightweight and conventional concrete beams exceeded their nominal flexural strengths, which were calculated without accounting for the splitting cracks that all manufactured lightweight concrete beams developed after the prestress release on their lower side. Based on these tests, upper bounds were determined for the development length of the prestressed strands with a diameter of 15.2. mm for the three types of concrete tested. Subsequently, the ductility factors of the beams tested under flexure were determined. Despite all of the tested beams were able to develop the full strength of the prestressed strands and showed a remarkably ductile behavior, it was concluded that the use of these lightweight concretes is not recommended in the fabrication of prestressed concrete bridge girders because of the potential reduction in their durability and bearing capacity due to stress corrosion, which is a result of the splitting cracks detected in all of the produced prestressed lightweight concrete beams. © 2013 Elsevier Ltd.},

abstract = {This article discusses an analytical model that relates the transfer length and the prestressing strand draw-in immediately after transfer; the model is based on the elastic confinement hypothesis of the prestressing strand using concrete and/or confining reinforcement. Two expressions are proposed to estimate upper and lower bounds on the transfer length, which consider the prestressing strand draw-in and the transferred effective prestress.

abstract = {This paper presents the results of an experimental program developed to study the feasibility of producing prestressed concrete girders using lightweight concrete. During the experimental campaign, bond tests were performed in push-in (TL bond test) and pull-out (FB bond test) types of specimens. To-scale prestressed concrete elements were produced, implemented, and tested. The variables studied were the type of concrete, the test age, and the delayed effects of bond. The TL bond test allowed the behavior of the transfer length to be characterized, governed by the Hoyer effect. Equations have been calibrated to identify the upper and lower transfer lengths using the experimental results of this trial. The proposed equations delimit the safety boundaries of the experimental transfer length values obtained in the experiments performed on the beams.

The appropriate design of a vertical slot fishway depends on an interplay between hydraulic and biological variables, since the hydrodynamic properties of the fishway must meet the requirements of the fish species for which it is intended. This paper presents a tool designed to analyze the efficiency of a fishway model according to biological criteria. The application can be used either in the analysis of an existing fishway or in the design process of a new one. It allows the user to choose between a wide range of geometric dimensions of the pools and the slot, and between different fish species. If it is being used as a design tool, it provides feasible fishway models sorted according to their biological efficiency. Considering the complexity of the hydraulic and biological phenomena involved in the process of swimming through a fishway, the tool presented here does not intend to determine an optimum design, but rather to establish an objective way for comparing different fishway designs, considering not only hydraulic aspects but also trying to quantify biological aspects of the target fish species. © 2011 Elsevier B.V.},

abstract = {One of the main issues in civil engineering is to analyze the behavior of materials in strength tests. Traditionally, information about displacements and strains in the materials is carried out from these tests using physical devices such as strain gauges or other transducers. Although these devices provide accurate and robust measurements in a wide range of situations, they are limited to obtaining measurements in a single point of the material and in a single direction of the movement, thus, the global behavior of the material cannot be analyzed. The proposed technique consists of the integration of a calibration process with a block-matching algorithm to measure displacements from images. This algorithm uses the similarity between regions in the images to extract the 2D vector displacement field from each point, and to quantify the strain on the surface of the material. The proposed algorithm has been designed to measure displacements from real images of material surfaces taken during strength tests, and it has the advantages of being robust with long-range displacements, of performing the analysis on the image space domain (avoiding the problems related to the use of Fourier Transforms), and of measurements in long sequences related to a real point of the material and not to a pixel position. © 2011 Computer-Aided Civil and Infrastructure Engineering.},

abstract = {The recognition of seizures is very important for the diagnosis of patients with epilepsy. The seizure is a process of rhythmic discharge in brain and occurs rarely and unpredictably. This behavior generates a need of an automatic detection of seizures by using the signals of long-term electroencephalographic (EEG) recordings. Due to the non-stationary character of EEG signals, the conventional methods of frequency analysis are not the best alternative to obtain good results in diagnostic purpose. The present work proposes a method of EEG signal analysis based on star graph topological indices (SGTIs) for the first time. The signal information, such as amplitude and time occurrence, is codified into invariant SGTIs which are the basis for the classification models that can discriminate the epileptic EEG records from the non-epileptic ones. The method with SGTIs and the simplest linear discriminant methods provide similar results to those previously published, which are based on the time-frequency analysis and artificial neural networks. Thus, this work proposes a simpler and faster alternative for automatic detection of seizures from the EEG recordings. © 2012 Elsevier B.V.},

The water level evolution at eight gauging points was measured as well as the final bed topography. Intense scour occurred close to the failed dam, while significant deposition was observed further downstream. From these experiments, a benchmark was proposed to the scientific community, consisting of blind test simulations, that is, without any prior knowledge of the measurements. Twelve different teams of modellers from eight countries participated in the study. Here, the numerical models used in this test are briefly presented.

abstract = {Vertical slot fishways are hydraulic structures that allow the upstream migration of fish through obstructions in rivers. The appropriate design of a vertical slot fishway depends on the interplay between hydraulic and biological variables because the hydrodynamic properties of the fishway must match the requirements of the fish species for which it is intended. One of the primary difficulties associated with studies of real fish behavior in fishway models is that the existing mechanisms to measure the behavior of the fish in these assays, such as direct observation or placement of sensors on the specimens, are impractical or unduly affect the animal behavior. This paper proposes a new procedure for measuring the behavior of the fish. The proposed technique uses artificial neural networks and computer vision techniques to analyze images obtained from the assays by means of a camera system designed for fishway integration. It is expected that this technique will provide detailed information about the fish behavior, and it will help to improve fish passage devices, which is currently a subject of interest in the area of civil engineering. A series of assays has been performed to validate this new approach in a full-scale fishway model with living fish. We have obtained very promising results that allow accurate reconstruction of the movements of the fish within the fishway. © 2011 American Society of Civil Engineers.},

The Evolutionary Computation (EC) and the Artificial Neural Networks (ANNs) have proved to be suitable in Data Mining for handling this type of series [3] [4]. This paper presents the use of Genetic Programming (GP) for the prediction of time series in the field of Civil Engineering where the predictive structure does not follow the classic paradigms. In this specific case, the GP technique is applied to two phenomenon that models the process where, for a specific area, the fallen rain concentrates and flows on the surface, and later from the water flows is predicted the solids transport. In this article it is shown the Genetic Programming technique use for the water flows and the solids transport prediction. It is achieved good results both in the water flow prediction as in the solids transport prediction. © 2011 Springer-Verlag Berlin Heidelberg.},

This paper presents a sensitivity and uncertainty analysis of a 2D depth-averaged water quality model applied to a shallow estuary. The model solves the mass transport equation for Escherichia Coli, including the effects of water temperature, salinity, solar radiation, turbulent diffusion and short wave dispersion. The sensitivity of the concentration of E. Coli in the estuary to input parameters and the different sources of uncertainty are studied using Global Sensitivity Analysis based on Monte Carlo simulation methods and sensitivity measures based on linear and non-linear regression analysis, in order to aid modellers in the calibration process and in the interpretation of model output. The extinction coefficient of light in water and the depth of the vertical layer over which the E.coli spread were found to be the most relevant parameters of the model. In the shallowest regions of the estuary errors in the bathymetry are also an important source of uncertainty on model output. Globally, the combination of these three parameters was found to be very effective for calibration purposes in the whole estuary. © 2011 Elsevier Ltd.},

Based on them, six recycled concretes with different percentages of replacement of natural coarse aggregates with recycled coarse aggregate (20, 50 and 100%) were obtained. To take into account the high absorption capacity of the recycled aggregates, before using them they were pre-wetted for 10 min. The results concluded that scalar damage mechanics (based on the variations of the elastic modulus) and volumetric strains curves can be use to quantify the damage of the recycled concrete. The results from both approaches indicated that the damage to concrete depended on the percentage of replacement, increasing with higher replacement percentages. Additionally, values of the damage, that are quantified using the critical stress and according to the scalar damage mechanics, are given. © RILEM 2011.},

The results made it possible to establish the differences between the stress-strain relationship of a conventional concrete and this relationship for a recycled concrete depending on the percentage of replacement. In this way, it was found that the longitudinal strain of the recycled concretes increases with the percentage of recycled coarse aggregate used. Finally, using the experimental results, an analytical expression of the stress-strain curve accounting for the percentage of replacement was developed. The verification of the proposed model equation was done by comparing it to the experimental data.

abstract = {About 1% of the people in the world suffer from epilepsy. The main characteristic of epilepsy is the recurrent seizures. Careful analysis of the electroencephalogram (EEG) recordings can provide valuable information for understanding the mechanisms behind epileptic disorders. Since epileptic seizures occur irregularly and unpredictably, automatic seizure detection in EEG recordings is highly required. Wavelet transform (WT) is an effective analysis tool for non-stationary signals, such as EEGs. The line length feature reflects the waveform dimensionality changes and is a measure sensitive to variation of the signal amplitude and frequency. This paper presents a novel method for automatic epileptic seizure detection, which uses line length features based on wavelet transform multiresolution decomposition and combines with an artificial neural network (ANN) to classify the EEG signals regarding the existence of seizure or not. To the knowledge of the authors, there exists no similar work in the literature. A famous public dataset was used to evaluate the proposed method. The high accuracy obtained for three different classification problems testified the great success of the method. © 2010 Elsevier B.V.},

For instance, Plasmodium falciparum causes the most severe form of Malaria and kills up to 2.7 million people annually whereas Plasmodium vivax is geographically the most widely distributed cause with more than 80 million clinical cases. Due to drug resistance and toxicity, discovering novel drug targets is mandatory; such as Protein-Protein Complexes unique in this pathogen and not present in human host (pPPCs). Additionally, the 3D structure of an increasing number of Plasmodium proteins is being reported in public databases making easier the development of bioinformatics models to predict pPPCs. In addition, some PPCs expressed both in parasite and human, such as DHFR synthase, play a significant role in drug resistance in both Malaria and Human Cancer. However, there are no general models to predict pPPCs using indices of PPC biopolymer structure. Therefore, we introduced herein new Markov Chain numerical descriptors of protein-protein Interactions (PPIs) based on electrostatic entropy measures and calculated these parameters for 5257 pairs of proteins (774 pPPCs and 4483 non-pPPCs) from more than 20 organisms, including parasite and human hosts.

abstract = {This paper presents the experimental validation and the application to a real industrial catchment of a two-dimensional depth-averaged shallow water model used for the computation of rainfall-runoff transformation from direct precipitation data. Instead of using the common approach in flood inundation modelling, which consists in computing the water depth and velocity fields given the water discharge, in this study the rainfall intensity is imposed directly in the model, the surface runoff being generated automatically. The model considers infiltration losses simultaneously with flow simulation. Gullies are also included in the model, although the coupling between the surface runoff and the sewer network is not considered. Experimental validation of the model is presented in several simplified laboratory configurations of urban catchments, in which the surface runoff has been measured for different hyetographs. The application to a real industrial catchment includes a sewer network flow component, which is solved with the SWMM model. The numerical predictions of the discharge hydrograph generated by a 12 hours storm event are compared with field measurements, providing encouraging results. © IWA Publishing 2010.},

This paper presents the results of a study on sixteen different designs of vertical slot fishways with two different slopes. The flow field is studied using both a physical-scale model and a numerical model which solves the 2D depth-averaged shallow water equations coupled with a k- eopen turbulence model. Several hydraulic parameters, such as the average velocity in the slot or the water depth, are considered in order to evaluate their biological efficiency. Based on the results, it appears that the length of the pool is the main geometric dimension that affects the flow in the fishway. The numerical and experimental agreement is very satisfactory. © 2010 Elsevier B.V.},

abstract = {This paper presents an experimental validation of two widely used numerical models in urban flood inundation studies, the two-dimensional dynamic and diffusive wave models. Instead of using the common approach in flood inundation modelling, which consists of computing the water depth and velocity fields for a given water discharge, in this study the rainfall intensity is imposed directly in the model, the surface runoff being generated automatically. Both the dynamic and diffusive wave models are implemented in the same unstructured finite volume code, removing in such a way any differences in the numerical discretisation other than the wave approximation used to compute the water velocity. Two different methods for representing buildings are used and compared, the so-called building-block and building-hole approaches. Experimental validation of the models is presented in several simplified laboratory configurations of urban catchments, in which the surface runoff has been measured for different hyetographs. For this purpose, 72 experiments were undertaken in a rainfall simulator, including eight catchment configurations and nine hyetographs. Numerical results show that the dynamic wave model is able to predict the peak discharge and its arrival time, as well as the shape of the outlet hydrograph, while the diffusive wave model gives less accurate results. The experimental validation confirms that, when the geometry of the problem is well defined, depth-averaged dynamic wave models may be used to predict rainfall-runoff from direct precipitation data in urban environments. © 2009 Elsevier B.V.

abstract = {The aim of this research was to determine the behavior of recycled concrete in response to the phenomenon of shear transfer. To perform it, a conventional control concrete and a concrete with 50% recycled coarse aggregate were designed. An additional goal was to shed light on how this behavior is modified with a pozzolanic addition, silica fume. Therefore, two types of concrete were designed, a conventional and a recycled concrete, both made with 8% of silica fume. In conclusion, a reduction of shear friction capacity was observed in recycled concretes, considerably higher in the case of the specimen without reinforcement. The addition of silica fume improved the behavior of recycled concretes. The results obtained were compared with the formulations of the different authors. In all cases, these were found to be conservative. However, the safety margins offered by recycled concretes are lower than those obtained with conventional concretes.},

abstract = {One of the key aspects that must be taken into consideration within the framework of Sustainable Construction is the management of Construction and Demolition (C&D) Debris. As for other types of waste, specific handling procedures are required to manage C&D Debris; these include reduction, reuse, recycling, and if all other possibilities fail, recovery or disposal. For public planning strategies aimed at the management of C&D Debris to be effective, it is first necessary to have specific knowledge of the type of waste materials generated in a particular region. After verifying that the methods available to determine the production and composition of C&D Debris are limited, this paper presents a procedure to ascertain the production and composition of C&D Debris, in any region. The procedure utilizes data on the surface areas of newly constructed buildings, renovations and demolitions, which are estimated from available data for recent years, as well as information on the quantity of debris generated per surface area in any type of construction site, which is obtained from recently executed constructions or from the ground plans of older buildings. The method proposed here has been applied to Galicia, one of Spain's autonomous communities, for which the quantity and composition of C&D Debris have been estimated for the horizon year 2011. © 2009 Elsevier Ltd.

Some excellent rational models have been developed; however, most of these models were too complex to be implemented in a code of practice. As a result, most concrete codes, as the European Code 2, are based on empirical formulations. Moreover, the EC-2 procedure does not take into account the bending moment-shear force interaction. In this paper, an improvement of this procedure is presented, with the main objective of predicting this interaction. The obtaining of the new expression was based on the use of Genetic Programming techniques. Two simple expressions are obtained, being one of them able to predict the bending moment-shear force interaction. Furthermore, the two equations significantly improve the adjustment with experimental results. © Civil-Comp Press, 2010.},

A further advantage lies in that no sensors are necessary within the flume. The system is particularly useful in the case of wave flume tests of floating bodies, such as an oil boom-the motions of the model boom are measured without any sensors in contact with it, which otherwise might place constraints on its displacements. The new method is validated based on free surface measurements carried out with a conventional wave gauge, with excellent results. © 2009 Elsevier Ltd. All rights reserved.},
