Jilte; Vikram Sundara; Mohammed Asif; Emanoil Linul;It is crucial to produce potable water from salt water in arid places using a stepped solar still desalination process. This work presents the temperature distribution and phase transformation of lauric acid PCM in inclined stepped solar still desalination system. A second-order finite volume method is employed for discretizing the two-dimensional geometry, while energy, continuity, and momentum equations are solved and then coupled using the second-order PRESTO algorithm. The solidification and melting CFD models have been used to capture the melting stages of lauric acid PCM. Four steps with an inclination of 30° to ground and two different cases with saline water levels of 10 mm and 40 mm have been reported. The results reveal that the temperature and mass fraction of lauric acid PCM strongly depends on the saline water level at each step, the number of steps, the angle of inclination, and the location of the solar still step. The maximum percentage increase in PCM melting fraction is 50%, and a PCM temperature rise of 4 °C is observed in the case of SWL-max compared to SWL-min. The total enthalpy of lauric acid PCM is increased by 30% for the SWL-max water level compared to the SWL-min water level.

Because the number of process variables in AM is large, extensive studies must be conducted in order to underline every particular influence. The study focuses on two variables—part orientation in the orthogonal horizontal plane and energy density—and targets two outcomes—geometric and tensile properties of the parts. The AM process was conducted on selective laser sintering (SLS) machine EOS Formiga P100 using EOS white powder polyamide (PA2200). After finishing the sinterization process, the parts were postprocessed, measured, weighted, and mechanically tested. The geometric evaluation and mass measurements of every sample allowed us to compute the density of all parts according to the sinterization energy and orientation, and to determine the relative error of every dimension. By conducting the tensile testing, the elastic and strength properties were determined according to process variables. A linear trend regarding sample density and energy density was identified. Also, large relative dimensional errors were recorded for the lowest energy density. Mechanical properties encountered the highest value for the highest energy density at a 45° orientation angle.

Because of the orthogonal trajectories of the laser beam during exposure, different orientations of the samples may lead to different mechanical properties. In order to reveal this process issue, four orientations of the samples in building envelope were investigated. For data reliability, all the other process parameters were constant for each material and every orientation. The tensile tests highlight small differences in elastic properties of the two materials, while significant differences in strength properties and energy absorption were observed. Nevertheless, Young modulus indicates high stiffness of the Alumide comparing to PA2200 samples. The stereo microscopy reveals a brittle fracture site for Alumide and a ductile fracture with longitudinal splitting zones for PA2200. From the orientation point of view, similar properties of samples oriented at 0 and 90 degrees for all investigated mechanical properties were observed. However, tensile strength was less influenced by the sample orientations.

Los yesos de aislamiento térmico se han convertido en el foco de atención en el sector de la construcción. Entre las razones más importantes de esto se encuentran las altas pérdidas de energía térmica de los edificios. Dado que las briquetas convencionales utilizadas en los edificios permiten una alta transferencia de calor, las industrias de la construcción están buscando formas alternativas de aislamiento con bajo costo y alta eficiencia térmica. El uso de yesos aislantes se está volviendo popular debido al alto costo y la instalación de materiales aislantes como el eps, que se encuentra entre las formas alternativas. Por lo tanto, en este estudio, el nuevo yeso aislante (NIP) desarrollado en contraste con los yesos aislantes tradicionales se prueba en briquetas convencionales de diferentes espesores. Al considerar el coeficiente de transferencia de calor total (valor U), se entiende que mientras que la briqueta convencional tiene el valor más alto con aproximadamente 5.5 W/m2K, la briqueta con 2-2 de espesor de línea de CONTACTO tiene el valor más bajo con un valor de casi 2.86 W/m2K. Como resultado de las pruebas, se observa que el coeficiente de transferencia de calor total de la briqueta con 1-1 de espesor de la línea de CONTACTO tiene una mejora de casi el 22,5% en comparación con las briquetas convencionales, mientras que se observa un progreso de aproximadamente el 36,4% en las briquetas con 2-1 de espesor de la línea de CONTACTO. Además, se revela que la mejor mitigación en el coeficiente general de transferencia de calor es de aproximadamente el 47,9% en briquetas con un espesor de 2-2 PELLIZCOS. También se ha descubierto que NIP tiene una durabilidad térmica adicional gracias a los poros de aire muertos y los minerales de boro en su estructura interna. Les plâtres d'isolation thermique sont devenus le centre d'attention dans le secteur du bâtiment. L'une des raisons les plus importantes en est les pertes élevées d'énergie thermique des bâtiments. Étant donné que les briquettes conventionnelles utilisées dans les bâtiments permettent un transfert de chaleur élevé, les industries de la construction recherchent des moyens d'isolation alternatifs à faible coût et à haute efficacité thermique. L'utilisation de plâtres isolants devient populaire en raison du coût élevé et de l'installation de matériaux isolants tels que l'EPS, qui fait partie des moyens alternatifs. Par conséquent, dans cette étude, le nouveau plâtre isolant (NIP) développé contrairement aux plâtres isolants traditionnels est testé sur des briquettes conventionnelles de différentes épaisseurs. En considérant le coefficient de transfert de chaleur total (valeur U), il est entendu que tandis que la briquette conventionnelle a la valeur la plus élevée avec environ 5,5 W/m2K, la briquette avec 2-2 épaisseur de PINCEMENT a la valeur la plus basse avec une valeur de près de 2,86 W/m2K. À la suite des tests, on observe que le coefficient de transfert de chaleur total de la briquette avec une épaisseur de PINCEMENT de 1-1 a une amélioration de près de 22,5 % par rapport aux briquettes conventionnelles, tandis qu'un progrès d'environ 36,4 % est observé dans les briquettes avec une épaisseur de PINCEMENT de 2-1. En outre, il est révélé que la meilleure atténuation du coefficient de transfert de chaleur global est d'environ 47,9 % dans les briquettes avec une épaisseur de 2 à 2 lignes de CONTACT. Il est également compris que NIP a une durabilité thermique supplémentaire grâce aux pores d'air morts et aux minéraux de bore dans sa structure interne. Thermal insulation plasters have become the focus of attention in the building sector. Among the most important reasons for this is the high thermal energy losses of the buildings. Since conventional briquettes used in buildings allow high heat transfer, the construction industries are looking for alternative insulation ways with low cost and high thermal efficiency. The use of insulation plasters is becoming popular due to the high cost and installation of insulation materials such as EPS, which is among the alternative ways. Therefore, in this study, the novel insulation plaster (NIP) developed in contrast to traditional insulation plasters is tested on conventional briquettes in different thicknesses. On considering the total heat transfer coefficient (U-value), it is understood that whilst the conventional briquette has the highest value with approximately 5.5 W/m2K, the briquette with 2-2 NIP thickness has the lowest value with a value of almost 2.86 W/m2K. As a result of the tests, the total heat transfer coefficient of the briquette with 1-1 NIP thickness is observed to have an improvement of nearly 22.5% compared to conventional briquettes, while a progress of approximately 36.4% is seen in briquettes with 2-1 NIP thickness. In addition, it is revealed that the best mitigation in the overall heat transfer coefficient is about 47.9% in briquettes with 2-2 NIP thickness. It is also figured out that NIP has additional thermal durability thanks to the dead air pores and boron minerals in its internal structure. أصبحت اللصقات العازلة للحرارة محور الاهتمام في قطاع البناء. ومن أهم أسباب ذلك ارتفاع خسائر الطاقة الحرارية للمباني. نظرًا لأن القوالب التقليدية المستخدمة في المباني تسمح بنقل الحرارة العالية، فإن صناعات البناء تبحث عن طرق عزل بديلة بتكلفة منخفضة وكفاءة حرارية عالية. أصبح استخدام اللصقات العازلة شائعًا بسبب التكلفة العالية وتركيب مواد العزل مثل EPS، والتي تعد من بين الطرق البديلة. لذلك، في هذه الدراسة، يتم اختبار جص العزل الجديد (NIP) الذي تم تطويره على النقيض من جص العزل التقليدي على قوالب القوالب التقليدية بسماكات مختلفة. عند النظر في إجمالي معامل نقل الحرارة (قيمة U)، من المفهوم أنه في حين أن فحم حجري تقليدي له أعلى قيمة بحوالي 5.5 واط/م 2 كيلو، فإن فحم حجري بسماكة 2-2 رشة له أدنى قيمة بقيمة 2.86 واط/م 2 كيلو تقريبًا. نتيجة للاختبارات، لوحظ أن معامل نقل الحرارة الكلي للفحم الحجري بسماكة 1-1 رقائق قد تحسن بنسبة 22.5 ٪ تقريبًا مقارنة بالفحم الحجري التقليدي، بينما لوحظ تقدم بنسبة 36.4 ٪ تقريبًا في الفحم الحجري بسماكة 2-1 رقائق. بالإضافة إلى ذلك، تم الكشف عن أن أفضل تخفيف في معامل نقل الحرارة الكلي هو حوالي 47.9 ٪ في القوالب بسماكة 2-2 NIP. من المعروف أيضًا أن NIP تتمتع بمتانة حرارية إضافية بفضل مسام الهواء الميتة ومعادن البورون في هيكلها الداخلي.

À la suite des tests, on observe que le coefficient de transfert de chaleur total de la briquette avec une épaisseur de PINCEMENT de 1-1 a une amélioration de près de 22,5 % par rapport aux briquettes conventionnelles, tandis qu'un progrès d'environ 36,4 % est observé dans les briquettes avec une épaisseur de PINCEMENT de 2-1. En outre, il est révélé que la meilleure atténuation du coefficient de transfert de chaleur global est d'environ 47,9 % dans les briquettes avec une épaisseur de 2 à 2 lignes de CONTACT. Il est également compris que NIP a une durabilité thermique supplémentaire grâce aux pores d'air morts et aux minéraux de bore dans sa structure interne. Thermal insulation plasters have become the focus of attention in the building sector. Among the most important reasons for this is the high thermal energy losses of the buildings. Since conventional briquettes used in buildings allow high heat transfer, the construction industries are looking for alternative insulation ways with low cost and high thermal efficiency. The use of insulation plasters is becoming popular due to the high cost and installation of insulation materials such as EPS, which is among the alternative ways. Therefore, in this study, the novel insulation plaster (NIP) developed in contrast to traditional insulation plasters is tested on conventional briquettes in different thicknesses. On considering the total heat transfer coefficient (U-value), it is understood that whilst the conventional briquette has the highest value with approximately 5.5 W/m2K, the briquette with 2-2 NIP thickness has the lowest value with a value of almost 2.86 W/m2K. As a result of the tests, the total heat transfer coefficient of the briquette with 1-1 NIP thickness is observed to have an improvement of nearly 22.5% compared to conventional briquettes, while a progress of approximately 36.4% is seen in briquettes with 2-1 NIP thickness. In addition, it is revealed that the best mitigation in the overall heat transfer coefficient is about 47.9% in briquettes with 2-2 NIP thickness. It is also figured out that NIP has additional thermal durability thanks to the dead air pores and boron minerals in its internal structure. أصبحت اللصقات العازلة للحرارة محور الاهتمام في قطاع البناء. ومن أهم أسباب ذلك ارتفاع خسائر الطاقة الحرارية للمباني. نظرًا لأن القوالب التقليدية المستخدمة في المباني تسمح بنقل الحرارة العالية، فإن صناعات البناء تبحث عن طرق عزل بديلة بتكلفة منخفضة وكفاءة حرارية عالية. أصبح استخدام اللصقات العازلة شائعًا بسبب التكلفة العالية وتركيب مواد العزل مثل EPS، والتي تعد من بين الطرق البديلة. لذلك، في هذه الدراسة، يتم اختبار جص العزل الجديد (NIP) الذي تم تطويره على النقيض من جص العزل التقليدي على قوالب القوالب التقليدية بسماكات مختلفة. عند النظر في إجمالي معامل نقل الحرارة (قيمة U)، من المفهوم أنه في حين أن فحم حجري تقليدي له أعلى قيمة بحوالي 5.5 واط/م 2 كيلو، فإن فحم حجري بسماكة 2-2 رشة له أدنى قيمة بقيمة 2.86 واط/م 2 كيلو تقريبًا. نتيجة للاختبارات، لوحظ أن معامل نقل الحرارة الكلي للفحم الحجري بسماكة 1-1 رقائق قد تحسن بنسبة 22.5 ٪ تقريبًا مقارنة بالفحم الحجري التقليدي، بينما لوحظ تقدم بنسبة 36.4 ٪ تقريبًا في الفحم الحجري بسماكة 2-1 رقائق. بالإضافة إلى ذلك، تم الكشف عن أن أفضل تخفيف في معامل نقل الحرارة الكلي هو حوالي 47.9 ٪ في القوالب بسماكة 2-2 NIP. من المعروف أيضًا أن NIP تتمتع بمتانة حرارية إضافية بفضل مسام الهواء الميتة ومعادن البورون في هيكلها الداخلي.

Coronary artery disease (CAD) is one of the most common causes of heart ailments; many patients with CAD do not exhibit initial symptoms. An electrocardiogram (ECG) is a diagnostic tool widely used to capture the abnormal activity of the heart and help with diagnoses. Assessing ECG signals may be challenging and time-consuming. Identifying abnormal ECG morphologies, especially in low amplitude curves, may be prone to error. Hence, a system that can automatically detect and assess the ECG and treadmill test ECG (TMT-ECG) signals will be helpful to the medical industry in detecting CAD. In the present work, we developed an intelligent system that can predict CAD, based on ECG and TMT signals more accurately than any other system developed thus far. The distinct convolutional neural network (CNN) architecture deals with single-lead and multi-lead (12-lead) ECG and TMT-ECG data effectively. While most artificial intelligence-based systems rely on the universal dataset, the current work used clinical lab data collected from a renowned hospital in the neighborhood. ECG and TMT-ECG graphs of normal and CAD patients were collected in the form of scanned reports. One-dimensional ECG data with all possible features were extracted from the scanned report with the help of a modified image processing method. This feature extraction procedure was integrated with the optimized architecture of the CNN model leading to a novel prediction system for CAD. The automated computer-assisted system helps in the detection and medication of CAD with a high prediction accuracy of 99%.

The experiments are performed in a single-cylinder, water-cooled, 1500 rpm, 3.5 kW power Compression Ignition (CI) engine under various loading conditions to examine the effects of CNG energy share on performance and emissions in Reactivity Controlled Compression Ignition (RCCI) combustion mode. The study found that the 30%CNG share decreased Nitrogen oxides (NOx) and smoke by 25 and 31%, as well as an increase in thermal efficiency of 4.35% in comparison to traditional biodiesel combustion. Finally, two machine learning (ML) models, namely the Gradient Boosting Regressor (GBR) and LASSO (Least Absolute Shrinkage and Selection Operator) Regression, were developed for predicting the dependent variables individually from the independent variables. Both the LASSO and GBR models achieved high accuracy with R2 values of 0.98–0.99 and relatively low Root Mean Square Error (RMSE) values.

From this point of view, a numerical study is carried out to examine the addition of silicon carbide nanoparticles in paraffin wax PCM, used as heat energy storing material in a semi-cylindrical solar water desalination system. The PCM temperature is maintained at 52 °C and the semi-cylindrical tubular section has a wall temperature of 85 °C. The top plane section of the tubular solar collector is made up of graphite material. A semi-circular cross-section is selected for numerical analysis. A finite volume solver is used for solving thermal and fluid flow governing equations. A pressure staggering option algorithm is applied for pressure–velocity coupling. The temporal parameters like temperature, velocity contours, melting fraction, enthalpy, and entropy of nano silicon embedded paraffin wax PCM are widely discussed. The results clearly show that the phase transition of solid PCM to fluid PCM is greatly influenced by nanoparticle addition and enhances the rate of heat transfer. Initially for the first 60 min the melting fraction and temperature of PCM remain uniform as the time step increases above 60 min the behavior of PCM changes abruptly which clearly indicates the random distribution of nanoparticles within the PCM. A critical time and temperature limit exists for nanoparticles-based PCM beyond which, the thermal efficiency of the solar water desalination system gets influenced.

The cylindrical thin-walled steel tube was filled with the closed-cell aluminum alloy foam that compressed under quasi-static loading conditions. During the compression test, the main mechanical properties of the ETs improved due to the interaction effect between the cellular structure of the foam and the inner wall of the empty tube. In addition, the initial propagated cracks on the steel tubes reduced considerably as a result of such interaction. Furthermore, the obtained results of the LL loading were compared with the axial loading (AL) results for both ETs and FFTs at the same temperature. The findings indicated that the application of loading on the lateral surface of the composite causes the lower mechanical properties of both ETs and FFTs in comparison with the axial loading conditions.

The melting process of beeswax phase change material within the cube geometry with constant wall temperature (65 °C) boundary condition has been investigated using solidification and melting model. The fluid flow and heat transfer governing equations are solved using second order finite volume scheme. A PRESTO algorithm is applied for pressure-velocity coupling. The convergence criteria of 10−10 have been selected for energy equation, while 10−8 is selected for both momentum and continuity equations. The results like percentage variation along length-height and height-width plane for transient liquid fraction and temperature has been plotted, along with velocity streamlines within the cube geometry. From the obtained results it is concluded that the melting fraction and temperature of beeswax PCM is different in different planes and the major factors which affect the complete melting process is wall temperature, and the geometry. A difference of more than 0.1 °C in temperature has been recorded between mid-length-height and height-width plane while a difference of more than 2% in liquid fraction of PCM is observed. Even the uniformity of temperature and liquid fraction is notably influenced and vary along length, height, and width of cube geometry. Thus, it is concluded that melting process of PCM may affect the ability to store and release the heat energy which further affect the performance parameters of applied physical system.

Jilte; Vikram Sundara; Mohammed Asif; Emanoil Linul;It is crucial to produce potable water from salt water in arid places using a stepped solar still desalination process. This work presents the temperature distribution and phase transformation of lauric acid PCM in inclined stepped solar still desalination system. A second-order finite volume method is employed for discretizing the two-dimensional geometry, while energy, continuity, and momentum equations are solved and then coupled using the second-order PRESTO algorithm. The solidification and melting CFD models have been used to capture the melting stages of lauric acid PCM. Four steps with an inclination of 30° to ground and two different cases with saline water levels of 10 mm and 40 mm have been reported. The results reveal that the temperature and mass fraction of lauric acid PCM strongly depends on the saline water level at each step, the number of steps, the angle of inclination, and the location of the solar still step. The maximum percentage increase in PCM melting fraction is 50%, and a PCM temperature rise of 4 °C is observed in the case of SWL-max compared to SWL-min. The total enthalpy of lauric acid PCM is increased by 30% for the SWL-max water level compared to the SWL-min water level.

Because the number of process variables in AM is large, extensive studies must be conducted in order to underline every particular influence. The study focuses on two variables—part orientation in the orthogonal horizontal plane and energy density—and targets two outcomes—geometric and tensile properties of the parts. The AM process was conducted on selective laser sintering (SLS) machine EOS Formiga P100 using EOS white powder polyamide (PA2200). After finishing the sinterization process, the parts were postprocessed, measured, weighted, and mechanically tested. The geometric evaluation and mass measurements of every sample allowed us to compute the density of all parts according to the sinterization energy and orientation, and to determine the relative error of every dimension. By conducting the tensile testing, the elastic and strength properties were determined according to process variables. A linear trend regarding sample density and energy density was identified. Also, large relative dimensional errors were recorded for the lowest energy density. Mechanical properties encountered the highest value for the highest energy density at a 45° orientation angle.

Because of the orthogonal trajectories of the laser beam during exposure, different orientations of the samples may lead to different mechanical properties. In order to reveal this process issue, four orientations of the samples in building envelope were investigated. For data reliability, all the other process parameters were constant for each material and every orientation. The tensile tests highlight small differences in elastic properties of the two materials, while significant differences in strength properties and energy absorption were observed. Nevertheless, Young modulus indicates high stiffness of the Alumide comparing to PA2200 samples. The stereo microscopy reveals a brittle fracture site for Alumide and a ductile fracture with longitudinal splitting zones for PA2200. From the orientation point of view, similar properties of samples oriented at 0 and 90 degrees for all investigated mechanical properties were observed. However, tensile strength was less influenced by the sample orientations.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article , Other literature type , Journal 2019Publisher:MDPI AG Authors: Dan Ioan Stoia; Emanoil Linul; Liviu Marsavina;This paper presents a study on the tensile properties of Alumide and polyamide PA2200 standard samples produced by Additive manufacturing (AM) based on selective laser sintering (SLS). Because of the orthogonal trajectories of the laser beam during exposure, different orientations of the samples may lead to different mechanical properties. In order to reveal this process issue, four orientations of the samples in building envelope were investigated. For data reliability, all the other process parameters were constant for each material and every orientation. The tensile tests highlight small differences in elastic properties of the two materials, while significant differences in strength properties and energy absorption were observed. Nevertheless, Young modulus indicates high stiffness of the Alumide comparing to PA2200 samples. The stereo microscopy reveals a brittle fracture site for Alumide and a ductile fracture with longitudinal splitting zones for PA2200. From the orientation point of view, similar properties of samples oriented at 0 and 90 degrees for all investigated mechanical properties were observed. However, tensile strength was less influenced by the sample orientations.

Los yesos de aislamiento térmico se han convertido en el foco de atención en el sector de la construcción. Entre las razones más importantes de esto se encuentran las altas pérdidas de energía térmica de los edificios. Dado que las briquetas convencionales utilizadas en los edificios permiten una alta transferencia de calor, las industrias de la construcción están buscando formas alternativas de aislamiento con bajo costo y alta eficiencia térmica. El uso de yesos aislantes se está volviendo popular debido al alto costo y la instalación de materiales aislantes como el eps, que se encuentra entre las formas alternativas. Por lo tanto, en este estudio, el nuevo yeso aislante (NIP) desarrollado en contraste con los yesos aislantes tradicionales se prueba en briquetas convencionales de diferentes espesores. Al considerar el coeficiente de transferencia de calor total (valor U), se entiende que mientras que la briqueta convencional tiene el valor más alto con aproximadamente 5.5 W/m2K, la briqueta con 2-2 de espesor de línea de CONTACTO tiene el valor más bajo con un valor de casi 2.86 W/m2K. Como resultado de las pruebas, se observa que el coeficiente de transferencia de calor total de la briqueta con 1-1 de espesor de la línea de CONTACTO tiene una mejora de casi el 22,5% en comparación con las briquetas convencionales, mientras que se observa un progreso de aproximadamente el 36,4% en las briquetas con 2-1 de espesor de la línea de CONTACTO. Además, se revela que la mejor mitigación en el coeficiente general de transferencia de calor es de aproximadamente el 47,9% en briquetas con un espesor de 2-2 PELLIZCOS. También se ha descubierto que NIP tiene una durabilidad térmica adicional gracias a los poros de aire muertos y los minerales de boro en su estructura interna. Les plâtres d'isolation thermique sont devenus le centre d'attention dans le secteur du bâtiment. L'une des raisons les plus importantes en est les pertes élevées d'énergie thermique des bâtiments. Étant donné que les briquettes conventionnelles utilisées dans les bâtiments permettent un transfert de chaleur élevé, les industries de la construction recherchent des moyens d'isolation alternatifs à faible coût et à haute efficacité thermique. L'utilisation de plâtres isolants devient populaire en raison du coût élevé et de l'installation de matériaux isolants tels que l'EPS, qui fait partie des moyens alternatifs. Par conséquent, dans cette étude, le nouveau plâtre isolant (NIP) développé contrairement aux plâtres isolants traditionnels est testé sur des briquettes conventionnelles de différentes épaisseurs. En considérant le coefficient de transfert de chaleur total (valeur U), il est entendu que tandis que la briquette conventionnelle a la valeur la plus élevée avec environ 5,5 W/m2K, la briquette avec 2-2 épaisseur de PINCEMENT a la valeur la plus basse avec une valeur de près de 2,86 W/m2K. À la suite des tests, on observe que le coefficient de transfert de chaleur total de la briquette avec une épaisseur de PINCEMENT de 1-1 a une amélioration de près de 22,5 % par rapport aux briquettes conventionnelles, tandis qu'un progrès d'environ 36,4 % est observé dans les briquettes avec une épaisseur de PINCEMENT de 2-1. En outre, il est révélé que la meilleure atténuation du coefficient de transfert de chaleur global est d'environ 47,9 % dans les briquettes avec une épaisseur de 2 à 2 lignes de CONTACT. Il est également compris que NIP a une durabilité thermique supplémentaire grâce aux pores d'air morts et aux minéraux de bore dans sa structure interne. Thermal insulation plasters have become the focus of attention in the building sector. Among the most important reasons for this is the high thermal energy losses of the buildings. Since conventional briquettes used in buildings allow high heat transfer, the construction industries are looking for alternative insulation ways with low cost and high thermal efficiency. The use of insulation plasters is becoming popular due to the high cost and installation of insulation materials such as EPS, which is among the alternative ways. Therefore, in this study, the novel insulation plaster (NIP) developed in contrast to traditional insulation plasters is tested on conventional briquettes in different thicknesses. On considering the total heat transfer coefficient (U-value), it is understood that whilst the conventional briquette has the highest value with approximately 5.5 W/m2K, the briquette with 2-2 NIP thickness has the lowest value with a value of almost 2.86 W/m2K. As a result of the tests, the total heat transfer coefficient of the briquette with 1-1 NIP thickness is observed to have an improvement of nearly 22.5% compared to conventional briquettes, while a progress of approximately 36.4% is seen in briquettes with 2-1 NIP thickness. In addition, it is revealed that the best mitigation in the overall heat transfer coefficient is about 47.9% in briquettes with 2-2 NIP thickness. It is also figured out that NIP has additional thermal durability thanks to the dead air pores and boron minerals in its internal structure. أصبحت اللصقات العازلة للحرارة محور الاهتمام في قطاع البناء. ومن أهم أسباب ذلك ارتفاع خسائر الطاقة الحرارية للمباني. نظرًا لأن القوالب التقليدية المستخدمة في المباني تسمح بنقل الحرارة العالية، فإن صناعات البناء تبحث عن طرق عزل بديلة بتكلفة منخفضة وكفاءة حرارية عالية. أصبح استخدام اللصقات العازلة شائعًا بسبب التكلفة العالية وتركيب مواد العزل مثل EPS، والتي تعد من بين الطرق البديلة. لذلك، في هذه الدراسة، يتم اختبار جص العزل الجديد (NIP) الذي تم تطويره على النقيض من جص العزل التقليدي على قوالب القوالب التقليدية بسماكات مختلفة. عند النظر في إجمالي معامل نقل الحرارة (قيمة U)، من المفهوم أنه في حين أن فحم حجري تقليدي له أعلى قيمة بحوالي 5.5 واط/م 2 كيلو، فإن فحم حجري بسماكة 2-2 رشة له أدنى قيمة بقيمة 2.86 واط/م 2 كيلو تقريبًا. نتيجة للاختبارات، لوحظ أن معامل نقل الحرارة الكلي للفحم الحجري بسماكة 1-1 رقائق قد تحسن بنسبة 22.5 ٪ تقريبًا مقارنة بالفحم الحجري التقليدي، بينما لوحظ تقدم بنسبة 36.4 ٪ تقريبًا في الفحم الحجري بسماكة 2-1 رقائق. بالإضافة إلى ذلك، تم الكشف عن أن أفضل تخفيف في معامل نقل الحرارة الكلي هو حوالي 47.9 ٪ في القوالب بسماكة 2-2 NIP. من المعروف أيضًا أن NIP تتمتع بمتانة حرارية إضافية بفضل مسام الهواء الميتة ومعادن البورون في هيكلها الداخلي.

Coronary artery disease (CAD) is one of the most common causes of heart ailments; many patients with CAD do not exhibit initial symptoms. An electrocardiogram (ECG) is a diagnostic tool widely used to capture the abnormal activity of the heart and help with diagnoses. Assessing ECG signals may be challenging and time-consuming. Identifying abnormal ECG morphologies, especially in low amplitude curves, may be prone to error. Hence, a system that can automatically detect and assess the ECG and treadmill test ECG (TMT-ECG) signals will be helpful to the medical industry in detecting CAD. In the present work, we developed an intelligent system that can predict CAD, based on ECG and TMT signals more accurately than any other system developed thus far. The distinct convolutional neural network (CNN) architecture deals with single-lead and multi-lead (12-lead) ECG and TMT-ECG data effectively. While most artificial intelligence-based systems rely on the universal dataset, the current work used clinical lab data collected from a renowned hospital in the neighborhood. ECG and TMT-ECG graphs of normal and CAD patients were collected in the form of scanned reports. One-dimensional ECG data with all possible features were extracted from the scanned report with the help of a modified image processing method. This feature extraction procedure was integrated with the optimized architecture of the CNN model leading to a novel prediction system for CAD. The automated computer-assisted system helps in the detection and medication of CAD with a high prediction accuracy of 99%.

The study found that the 30%CNG share decreased Nitrogen oxides (NOx) and smoke by 25 and 31%, as well as an increase in thermal efficiency of 4.35% in comparison to traditional biodiesel combustion. Finally, two machine learning (ML) models, namely the Gradient Boosting Regressor (GBR) and LASSO (Least Absolute Shrinkage and Selection Operator) Regression, were developed for predicting the dependent variables individually from the independent variables. Both the LASSO and GBR models achieved high accuracy with R2 values of 0.98–0.99 and relatively low Root Mean Square Error (RMSE) values.

Ramesh; Asif Afzal; Ümit Ağbulut; Sher Afghan Khan; Mohammed Asif; Vijayanandh Raja; Emanoil Linul;Adding nanoparticles in phase change material (PCM) is a new trend for enhancing their thermal energy-storing ability as well as thermal conductivity. From this point of view, a numerical study is carried out to examine the addition of silicon carbide nanoparticles in paraffin wax PCM, used as heat energy storing material in a semi-cylindrical solar water desalination system. The PCM temperature is maintained at 52 °C and the semi-cylindrical tubular section has a wall temperature of 85 °C. The top plane section of the tubular solar collector is made up of graphite material. A semi-circular cross-section is selected for numerical analysis. A finite volume solver is used for solving thermal and fluid flow governing equations. A pressure staggering option algorithm is applied for pressure–velocity coupling. The temporal parameters like temperature, velocity contours, melting fraction, enthalpy, and entropy of nano silicon embedded paraffin wax PCM are widely discussed. The results clearly show that the phase transition of solid PCM to fluid PCM is greatly influenced by nanoparticle addition and enhances the rate of heat transfer. Initially for the first 60 min the melting fraction and temperature of PCM remain uniform as the time step increases above 60 min the behavior of PCM changes abruptly which clearly indicates the random distribution of nanoparticles within the PCM. A critical time and temperature limit exists for nanoparticles-based PCM beyond which, the thermal efficiency of the solar water desalination system gets influenced.

The cylindrical thin-walled steel tube was filled with the closed-cell aluminum alloy foam that compressed under quasi-static loading conditions. During the compression test, the main mechanical properties of the ETs improved due to the interaction effect between the cellular structure of the foam and the inner wall of the empty tube. In addition, the initial propagated cracks on the steel tubes reduced considerably as a result of such interaction. Furthermore, the obtained results of the LL loading were compared with the axial loading (AL) results for both ETs and FFTs at the same temperature. The findings indicated that the application of loading on the lateral surface of the composite causes the lower mechanical properties of both ETs and FFTs in comparison with the axial loading conditions.

Ramesh; Vijayanandh Raja; Emanoil Linul; Sher Afghan Khan; Mohammed Asif; Abdulrajak Buradi; Olusegun David Samuel;The ability of phase change materials (PCM) to store thermal energy has gained wide application area, like battery thermal management, solar water desalination and many other. The melting process of beeswax phase change material within the cube geometry with constant wall temperature (65 °C) boundary condition has been investigated using solidification and melting model. The fluid flow and heat transfer governing equations are solved using second order finite volume scheme. A PRESTO algorithm is applied for pressure-velocity coupling. The convergence criteria of 10−10 have been selected for energy equation, while 10−8 is selected for both momentum and continuity equations. The results like percentage variation along length-height and height-width plane for transient liquid fraction and temperature has been plotted, along with velocity streamlines within the cube geometry. From the obtained results it is concluded that the melting fraction and temperature of beeswax PCM is different in different planes and the major factors which affect the complete melting process is wall temperature, and the geometry. A difference of more than 0.1 °C in temperature has been recorded between mid-length-height and height-width plane while a difference of more than 2% in liquid fraction of PCM is observed. Even the uniformity of temperature and liquid fraction is notably influenced and vary along length, height, and width of cube geometry. Thus, it is concluded that melting process of PCM may affect the ability to store and release the heat energy which further affect the performance parameters of applied physical system.
