El Mehdi LAADISSI ) (Zakaria Er-reguig) Sat, 25 Sep 2021 09:24:19 -0400 OJS 60 Free Convection Heat Transfer of Alumina-Water Nanofluid in an Enclosure: Assessment of Viscosity and Conductivity Models <p>In this paper, the free convection heat transfer of Al<sub>2</sub>O<sub>3</sub>-Water nanofluid in a square cavity is simulated, employing the finite volume technique. The homogeneous model is utilized to determine the influence of nanoparticles. The obtained results are compared with the experiment. At higher Rayleigh numbers, higher agreement between the results is observed. The nanofluid average Nusselt number increases with the Rayleigh number. For a concentration of 0.1%, the average Nusselt number increases, and for higher concentrations, it decreases, as compared with the pure fluid. Different viscosity and conductivity models were evaluated. It was found that the viscosity correlation, which takes into account the Brownian motion effect, produces more accurate results. The results obtained using different conductivity correlations were almost the same.</p> Farshid Narges-Moghadam, Pedram Pournaderi Copyright (c) The Elasticity and viscosity of polyvinyl alcohol / sodium bicarbonate (PVA/ NaHCO3) and polyvinyl alcohol /sodium chloride (PVA/ NaCl) samples <p>&nbsp;&nbsp;&nbsp; Poly (vinyl alcohol) solutions of different concentrations (0.1, 0.2, 0.3, 0.4, 0.5%) of&nbsp; Sodium bicarbonate and Sodium chloride were&nbsp; prepared, then poured onto a level glass plate and allowed to dry at room temperature for approximately 120 h. Thin films almost 0.05 mm thick were formed. The changes in the length of the thin films by the effect of increasing loads and the solutions’s flow time were measured for all solutions, which was used to calculate the viscosities, stress and strain of the samples. The results in this research indicate that the elasticity of the samples in the case of NaHCO<sub>3</sub> decreased, while in the case of NaCl it increased, as well as the Young’s modulus, but with a comparable viscosities, it was impact resistance of PVA/ NaHCO3 was higher than that of PVA / NaCl.</p> <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;These results can be used to improve the properties of polymers, their solutions and segments, to benefit from them in many fields, such as industrial and medical applications and scientific studies.</p> Najla Ali Copyright (c) Face Mask Detection with alert system using Tensorflow, Keras and OpenCV <table width="593"> <tbody> <tr> <td width="387"> <p>As Covid-19 is increasing day by day, it is important to make sure that we should overcome from this. But the question arises here is that how we can overcome from this? like wearing mask, sanitizing ourself, taking necessary precautions and all. Nowadays vaccines are must, do you really think after getting vaccinated you are safe? The answer is no vaccines are to boost up our immunity level, so that if you get infected it will be not much harmful to you, so here we have implemented an application Face mask detection with alert system where we can get to know that whether the person is wearing a mask or not. If person is not wearing a mask in the premises, campus a beep sound is generated to catch that person. In this application a screen is displayed which detects the human face with or without mask and shows the percentage score of the mask worn. This application will be useful for the areas were number of peoples are more like hotels, airport, schools and colleges. Here first the model is trained on a real-world dataset having with or without face mask and then we have trained our model with live video streaming. The accuracy is obtained by increasing and decreasing the epoch value.</p> </td> </tr> </tbody> </table> Sakshi Tiwari, Vishal Chaudhari, Vaishali Patil Copyright (c)
