    LAMINAR FORCED CONVECTION AND PERFORMANCE EVALUATION IN A SQUARE DUCT HEAT EXCHANGER PLACED WITH WAVY THIN RIB

    Amnart Boonloia, Withada Jedsadaratanachaib,*

    Frontiers in Heat and Mass Transfer, Vol.15, pp. 1-15, 2020, DOI:10.5098/hmt.15.13

    Abstract Simulated examinations on convective heat transfer and flow topology in a square duct heat exchanger placed with wavy thin rib (WTR) are presented. The influences of WTR heights, pitch distances and flow directions on flow and heat transfer characteristics are investigated for the laminar flow regime at the inlet condition (Re = 100 – 2000). The finite volume method (SIMPLE algorithm) is picked to analyze the numerical problem. The numerical validations; grid independence and verification of the smooth duct, are presented. The simulated results of the heat exchanger duct placed with WTR are reported in terms of flow and heat… More >

    Développement et évaluation d’un programme d’entraînement à la communication hypnotique à destination des infirmières en oncologie pédiatrique : la formation Rel@x

    D. Ogez, J. Aramideh, E. Rondeau, T. Mizrahi, M.-C. Charest , C. Plante, M. Duval, S. Sultan

    Psycho-Oncologie, Vol.16, No.1, pp. 199-205, 2022, DOI:10.3166/pson-2022-0185

    Abstract Les enfants atteints d’un cancer sont régulièrement confrontés à des procédures douloureuses au cours de leur prise en charge. Afin de les accompagner au mieux dans leurs soins, des techniques de communication dérivées de l’hypnose ont montré d’excellents niveaux d’efficacité sur la réduction de la détresse et de la douleur associées à ces procédures. Nous avons mené une étude préliminaire évaluant les effets d’une formation à la communication hypnotique sur la pratique des infirmières lors de procédures douloureuses auprès d’enfants atteints d’un cancer. Les résultats ont montré une bonne acquisition des techniques par les infirmières et des effets importants de… More >

    VIEWPOINT

    Liquid biopsy and blood-based minimal residual disease evaluation in multiple myeloma

    ALESSANDRO GOZZETTI*, MONICA BOCCHIA

    Oncology Research, Vol.31, No.3, pp. 271-274, 2023, DOI:10.32604/or.2023.028668

    Abstract Novel drug availability has increased the depth of response and revolutionised the outcomes of multiple myeloma patients. Minimal residual disease evaluation is a surrogate for progression-free survival and overall survival and has become widely used not-only in clinical trials but also in daily patient management. Bone marrow aspiration is the gold standard for response evaluation, but due to the patchy nature of myeloma, false negatives are possible. Liquid biopsy and blood-based minimal residual disease evaluation consider circulating plasma cells, mass spectrometry or circulating tumour DNA. This approach is less invasive, can provide a more comprehensive picture of the disease and… More >

    Vers une mesure des « vides alimentaires » dans un contexte urbain hétérogène

    Réflexion méthodologique et application à Lyon-Saint-Étienne

    Luc Merchez1 , Hélène Mathian2 , Julie Le Gall3

    Revue Internationale de Géomatique, Vol.30, No.1, pp. 85-104, 2020, DOI:10.3166/rig.2020.00103

    Abstract La question de l’alimentation et de la caractérisation des environnements alimentaires a déjà fait l’objet de nombreuses études et développements méthodologiques pour rendre compte des différentiels d’accessibilité. Aux Etats-Unis, essentiellement à l’aune de questions sur la santé, ces études ont conduit à identifier des « déserts alimentaires . Cette question éminemment spatiale, qui repose sur la notion d’accessibilité, est souvent approchée par des enquêtes et entretiens ou des approches quantitatives basées sur des calculs d’accessibilités géographiques. Dans la lignée de ces travaux, nous proposons d’explorer la transférabilité de cette notion de « désert » à un espace métropolitain français. La… More >

    Visualization for Explanation of Deep Learning-Based Defect Detection Model Using Class Activation Map

    Hyunkyu Shin1, Yonghan Ahn2, Mihwa Song3, Heungbae Gil3, Jungsik Choi4,*, Sanghyo Lee5,*

    CMC-Computers, Materials & Continua, Vol.75, No.3, pp. 4753-4766, 2023, DOI:10.32604/cmc.2023.038362

    Abstract Recently, convolutional neural network (CNN)-based visual inspection has been developed to detect defects on building surfaces automatically. The CNN model demonstrates remarkable accuracy in image data analysis; however, the predicted results have uncertainty in providing accurate information to users because of the “black box” problem in the deep learning model. Therefore, this study proposes a visual explanation method to overcome the uncertainty limitation of CNN-based defect identification. The visual representative gradient-weights class activation mapping (Grad-CAM) method is adopted to provide visually explainable information. A visualizing evaluation index is proposed to quantitatively analyze visual representations; this index reflects a rough estimate… More >

    Google Scholar University Ranking Algorithm to Evaluate the Quality of Institutional Research

    Noor Ul Sabah1, Muhammad Murad Khan1,*, Ramzan Talib1, Muhammad Anwar2, Muhammad Sheraz Arshad Malik3, Puteri Nor Ellyza Nohuddin4

    CMC-Computers, Materials & Continua, Vol.75, No.3, pp. 4955-4972, 2023, DOI:10.32604/cmc.2023.037436

    Abstract Education quality has undoubtedly become an important local and international benchmark for education, and an institute’s ranking is assessed based on the quality of education, research projects, theses, and dissertations, which has always been controversial. Hence, this research paper is influenced by the institutes ranking all over the world. The data of institutes are obtained through Google Scholar (GS), as input to investigate the United Kingdom’s Research Excellence Framework (UK-REF) process. For this purpose, the current research used a Bespoke Program to evaluate the institutes’ ranking based on their source. The bespoke program requires changes to improve the results by… More >

    PERFORMANCE EVALUATION OF A SOLAR WATER HEATER INTEGRATED WITH BUILT-IN THERMAL ENERGY STORAGE VIA POROUS MEDIA

    Hasan S. Majdia,*, Azher M. Abedb, Laith J. Habeebc

    Frontiers in Heat and Mass Transfer, Vol.17, pp. 1-7, 2021, DOI:10.5098/hmt.17.6

    Abstract The present work presents and analyzes the results acquired from outdoor experimental measurements of a solar latent heat storage unit integrated with built-in thermal energy storage at the presence and absence of porous media. The tank consists of a porous media part, a packed of glass beds, and the fluid flowing through the void space surrounding the porous glass beds. The porous tanks were filled by 1.68 mm glass beds to form bed heights (h) of 10 and 20 cm. Results show that the maximum thermal storage of 110 min is achieved in hot flow rate qh=4 LPM, cold flow… More >

    EVALUATION OF THE USE OF CONSTRAINTS IN STEP-BY-STEP ALGORITHMS FOR THE SOLUTION OF A 2D INVERSE HEAT TRANSFER PROBLEM

    Rodrigo Vidonscky Pintoa , Flávio Augusto Sanzovo Fiorellib,*

    Frontiers in Heat and Mass Transfer, Vol.19, pp. 1-10, 2022, DOI:10.5098/hmt.19.30

    Abstract The present paper provides a discussion about the use of constraints in step-by-step optimization algorithms used for the solution of a twodimensional inverse heat transfer problem containing a modeling error. It is observed that the unrestricted algorithms provided better estimates to the power map and the introduction of constraints is harmful to the solution of the inverse heat transfer problem, reducing the area in which this solution approaches the actual heat sources distribution, due to the solution of the unrestricted problem adopting negative values in restricted areas, which compensate the high sensitivity of this problem and consequently provide improved solutions.
