The location and nature of the moisture leakages are sometimes difficult to detect. Moreover, the relation between observed inside surface moisture patterns and where the moisture enters the construction is often not clear. The objective of this paper is to investigate inverse modeling techniques as a tool for the detection of moisture leakage locations in building constructions from inside ...

In this paper, we develop a mathematical model to simulate the movement of bacteria into and within a capillary segment. Also, we model the transportation through capillary walls by means of anisotropic diffusivity that depends on the pressure difference across the capillary walls. By solving the model using COMSOL, it was possible to predict the concentration of bacteria at points within the ...

A simple design for a microfluidic flow system for use in mixing or reacting assays with limited sample availability has been proposed and analyzed using COMSOL\'s multiphysics simulation package. The design is based on differential electroosmotic flow concept which has facilitated a number of interesting flow phenomena in micro-domains. For an average potential drop of about 86 kV/m in the ...

A lot of techniques are developed to treat soils polluted by hydrocarbons pollutants: incineration, thermal treatment, extraction, chemical oxidation, bioremediation… Some of these techniques are very energy consuming (incineration, thermal treatment…) and often need a subsequent treatment of the generated gases or liquids. Of all the decontamination methods, bioremediation appears to be the ...

Cowpea seed is a pulse which is very rich in vital micronutrients but also in anti-nutritional factors such as α-galactosides (verbascose, stachyose and raffinose) that can cause digestive disorders after consumption. The objective of this work was to identify the transport and reactivity properties of α-galactosides as a function of soaking-cooking process conditions (time, temperature, etc.) ...

Structural safety assessment of cultural heritage masonry structures plays an important role in safeguarding their integrity and conservation. In this regard, masonry modeling is one of the most challenging tasks, since an accurate reproduction of its mechanical behavior is necessary to assess the overall bearing capacity of the structures. In Finite Elements Methods, a realistic constitutive ...

In the last few years printable electronics has gained a great deal of interest since it promises mechanical flexibility and extremely low production costs. One approach to achieve printable electronic devices relies on the usage of specific inks containing e.g. dispersed semiconductor nanoparticles, where the latter are then apt to further processing steps. In this work, doped silicon (Si) ...

Assessing the severity of the internal corrosion of structures is of paramount importance in the oil & gas industry. Modelling and simulation of this process proved to be key techniques to understand its mechanism and the main factors influencing its severity [1-4]. Considerable effort has been deployed to implement an adequate electrochemical process of the corrosion phenomenon [5-12]. ...

Additive Manufacturing is revolutionizing the industrial sector for complex and individualized metallic components. The most limiting factor of the widely established laser beam melting technology is the scan velocity due to inertia of the mirrors . In electron beam melting (EBM), this aspect is not relevant because electromagnetic coils are used for the deflection. To ensure a stable process ...
