OpenVisConf - WebGL for graphics and data visualization
OpenVisConf - WebGL for graphics and data visualizationphilogb WebGL is an API for accessing the GPU from JavaScript to perform graphics and data visualization. It can be used for exploratory visualizations, real-time data analysis, scientific visualization, and data art. WebGL works by using JavaScript to compile GLSL shaders that run on the GPU. Shaders are programs that run on the GPU and are written in GLSL, a C-like language made for graphics with built-in functions. An example application is the Hopf fibration, which maps points on a 3D sphere to circles on a 4D sphere using WebGL.

Sustainable Innovation with Immersive Learning
Sustainable Innovation with Immersive LearningLeonel Morgado Prof. Leonel and Prof. Dennis approached educational uses, practices, and strategies of using immersion as a lens to interpret, design, and planning educational activities in a sustainable way. Rather than one-off gimmicks, the intent is to enable instructors (and institutions) to be able to include them in their regular activities, including the ability to evaluate and redesign them.
Immersion as a phenomenon enables interpreting pedagogical activities in a learning-agnostic way: you take a stance on the learning theory to follow, and leverage immersion to envision and guide your practice.
THE PSYCHOANALYTIC OF THE BLACK CAT BY EDGAR ALLAN POE (1).pdf
THE PSYCHOANALYTIC OF THE BLACK CAT BY EDGAR ALLAN POE (1).pdfnabilahk908 Psychoanalytic Analysis of The Black Cat by Edgar Allan Poe explores the deep psychological dimensions of the narrator’s disturbed mind through the lens of Sigmund Freud’s psychoanalytic theory. According to Freud (1923), the human psyche is structured into three components: the Id, which contains primitive and unconscious desires; the Ego, which operates on the reality principle and mediates between the Id and the external world; and the Superego, which reflects internalized moral standards.
In this story, Poe presents a narrator who experiences a psychological breakdown triggered by repressed guilt, aggression, and internal conflict. This analysis focuses not only on the gothic horror elements of the narrative but also on the narrator’s mental instability and emotional repression, demonstrating how the imbalance of these three psychic forces contributes to his downfall.

Chalukyas of Gujrat, Solanki Dynasty NEP.pptxDr. Ravi Shankar Arya Mahila P. G. College, Banaras Hindu University, Varanasi, India. This presentation has been made keeping in mind the students of undergraduate and postgraduate level. In this slide try to present the brief history of Chaulukyas of Gujrat up to Kumarpala To keep the facts in a natural form and to display the material in more detail, the help of various books, websites and online medium has been taken. Whatever medium the material or facts have been taken from, an attempt has been made by the presenter to give their reference at the end.
Chaulukya or Solanki was one of the Rajputs born from Agnikul. In the Vadnagar inscription, the origin of this dynasty is told from Brahma's Chauluk or Kamandalu. They ruled in Gujarat from the latter half of the tenth century to the beginning of the thirteenth century. Their capital was in Anahilwad. It is not certain whether it had any relation with the Chalukya dynasty of the south or not. It is worth mentioning that the name of the dynasty of the south was 'Chaluky' while the dynasty of Gujarat has been called 'Chaulukya'. The rulers of this dynasty were the supporters and patrons of Jainism.
