Segmentation And Classification Of Left Ventricular Abnormalities In Cardiac Mri Using Initial Point Prediction Based Deformable Model, Md. Asadur Rahman, Md. Al Noman, A. B. M. Aowlad Hossain

Future Computing and Informatics Journal

The shape of the left ventricle (LV) of a cardiac magnetic resonance image (CMRI) helps physicians to diagnose different cardiac abnormalities. The similarity of pixel intensity and shape of LV with neighbor tissues, the imprecision of boundaries, and the presence of noise are the challenges to accurate segmentation of LV. This paper contributes to the successful implementation of an automatic edge contouring method to segment LV area from CMRI and detect whether the ventricle belongs to abnormalities. This method proposes the regression-based artificial neural network to predict the possible initial position of the deformable edge-based active contour model for precise …

ABSTRACT

This study aimed to evaluate the performance of an electrocoagulation reactor (EC) and investigate its efficiency in heavy-polluted industrial wastewater treatment. The electrocoagulation (EC) reactor has been experimentally evaluated using aluminium (Al) electrodes and connected to a direct current power at various applied voltage levels at room temperature in a relatively limited reaction time.

The treatment performance efficiency of the selected dominant EC operating parameter groups: pH, reaction time, inter-electrode distance, and applied voltage was investigated. The results demonstrate that the applied voltage to the electrocoagulation reactor was the most significant factor in pollutant removal. The maximum total suspended …

Kompost*Klang*Küche*: Telematic Worlding With Glitch, Hannah Vyborg Walter, Robert Torche, Cedric Spindler, Eric Larrieux, Patrick Muller

Journal of Network Music and Arts

This paper explores concepts and practices of telematic performances, particularly through the lens of the project kompost*klang*küche*. It emphasizes spatial discontinuity within networked artistic collaborations, as opposed to immersive continuity.

Telematic performance formats utilize network technologies to facilitate low latency artistic endeavors across geographical divides, creating a complex interplay between local, remote, and intermediary spaces. In this context, we interpret spatial configurations from a phenomenological point of view as telematic SPACE in which technical components are in place in three spaces (local, remote and intermediary space) while practiced, embodied and inhabited in an anthropological space, where the overlay and dynamics …

How To Be In Two Places At Once: A Search For The Immersive Experience In Renaissance Music And Visual Arts., Andrew Hallock

Journal of Network Music and Arts

Immersion is a hot topic, but it is often invoked in a vague or shallow way. This essay aims to arrive at a more nuanced consideration of the immersive experience by presenting some perhaps surprising arguments from the past—from Renaissance music and visual arts—drawing parallels with our own time, and positing that the Network Arts can take inspiration from this history to enhance its own immersive endeavours. Four interrelated topics serve as the basis for this investigation: miniature devotionalia, polyphonic canons, anamorphic puzzles, and early cosmology. By using perspective to disclose hidden meanings, ideas, and realities, these varied practices draw …
