Surveying theories and philosophies of mathematics education
No full textAny theory of thinking or teaching or learning rests on an underlying philosophy of knowledge. Mathematics education is situated at the nexus of two fields of inquiry, namely mathematics and education. However, numerous other disciplines interact with these two fields which compound the complexity of developing theories that define mathematics education. We first address the issue of clarifying a philosophy of mathematics education before attempting to answer whether theories of mathematics education are constructible? In doing so we draw on the \ud
foundational writings of Lincoln and Guba (1994), in which they clearly posit that any discipline within education, in our case mathematics education, needs to clarify for itself the following questions:\ud
\ud
(1) What is reality? Or what is the nature of the world around us?\ud
\ud
(2) How do we go about knowing the world around us? [the methodological question, which presents possibilities to various disciplines to develop methodological paradigms] and,\ud
\ud
(3) How can we be certain in the “truth” of what we know? [the epistemological question]\ud

Notules sur Emptiness: A Double Comic Strip de Bharath Murthy
No full textÀ travers ces 12 notules je cherche à montrer comment l’auteur Bharath Murthy a su développer une BD « scientifique » ici plus concrètement philosophique sur le la présence-absence d’une essence appelée « âme » (ou « moi », « soi », « dieu », etc.) dans la tradition occidentale et réaffirmée jusque dans l’IA par certains, et déconstruite par l’« emptiness » aporétique bouddhique en utilisant les techniques spécifiques de la bande dessinée procurées par le texte et l’image (du bleed à la graphiation).Through these 12 “footnotes” I try to show how the author Bharath Murthy has been able to develop a "scientific" comic strip, here more concretely a philosophical one, on the presence-absence of an essence called "soul" (or "self", "self", "god", etc.) in the Western tradition and reaffirmed in AI by some, and deconstructed by the Buddhist aporetic "emptiness", using the specific techniques of comics provided by the text and the image (from bleed to graphiation)
Bharath M.R.pdf
No full text Image enhancement is a never-ending area of agile research. Standardizing the image quality is always a challenge in the imaging research field to achieve optimal imaging. One of the popular visual enhancement methods widely used in medical image enhancement named CLAHE (Contrast Limited Adaptive Histogram Equalization), in which the contrast of the local regions is increased, thereby enhancing the local information of an image. This paper proposes a scheme to extract the finger veins from the captured image background surface using bifold CLAHE technique. We apply CLAHE on finger ROI followed by finger vein ROI to enhance the finger vein pattern, then apply binarization based on Otsu thresholding in Canny edge detection to obtain optimum finger vein edges. Experimental results show that, for a given set of input images, our proposed bifold CLAHE where N and CL are calculated experimentally outperforms in terms of contrast enhancement there by containing the more image information compare to legacy methods. </p

This dataset contains:
- tuft_analysis_CFD.ipynb : jupyter notebook for creating the model based on CFD data
- tuft_analysis_experimental.ipynb : jupyter notebook for creating the models based on experimental data
> lift_nn_model : folder containing the files that make up the lift model for experimental data
> moment_nn_model : folder containing the files that make up the moment model for experimental data
> lift_nn_model_cfd : folder containing the files that make up the lift model for CFD data
> CFD_data : folder containing the suction surface parameters on the wing obtained with CFD
> experimental_data : folder contain the data obtained from experiments in the wind tunnel and prepared for analysis
> images : 3 sample images for a single angle of attack and velocity
> ML_data: for each angle of attack the full tuft locations (fixed and free end), lift and moment.
By utilising the jupyter notebooks the .npy (numpy arrays) with data are automatically loaded and used to create new models based on the data. It is also possible to load the included models. Running the full notebooks will produce the equivalent figures as shown in the paper.</span
A Novel Decision-Support Framework for Supporting Renewable Energy Technology Siting in the Early Design Stage of Microgrids: Considering Geographical Conditions and Focusing on Resilience and SDGs
No full textThis research is focused on microgrid design supporting tools and presents an innovative framework for renewable energy (RE) sources’ site selection, integrating multicriteria decision-making (MCDM) methods with resilience considerations and alignment to the Sustainable Development Goals (SDGs). It addresses present climatic challenges, identifies key causes of possible power failures, and develops strategies to mitigate their effects, while providing tools for energy managers and decision-makers to select suitable RE sources/technologies, based on geographical and sustainability criteria. The framework categorizes criteria into quantitative and qualitative types, adopting a cost (C)- and benefit (B)-based approach. The Analytic Hierarchy Process (AHP) calculates criteria weights to ensure accuracy and compatibility in decision-making, integrating SDG objectives into the evaluation process. This study focuses on five major RE options, photovoltaic (PV), wind, wave, tidal, and geothermal, analyzing more than 50 criteria for each energy type. This evaluation incorporates the expertise of over 50 experts and case studies, making it one of the most extensive research efforts in RE site selection. By systematically addressing resilience challenges and linking them with SDG priorities, this study provides a robust framework for evaluating and optimizing RE options. Its methodologies offer significant contributions to advancing sustainable energy development and enhancing energy systems’ resilience to climate and infrastructural challenges
