As urbanisation continues to draw more people into cities worldwide, the concentration of particulate matter (PM) in urban air quality emerges as a significant global concern. Poor air quality poses a health risk to everyone and contributes…

Simplex-structured matrix factorisation

Let \(X \in \mathbb {R}^{n \times p}\) be a data matrix with n observations and p variables; each row of X corresponds to an observation in the p-dimensional space. Simplex-structured matrix factorisation…

Metaheuristic optimization algorithms (MOAs) have been showing great interest recently. The spikes in the number of publications show the recent interest of researchers and designers in this important optimization tool as shown in Fig. 1. This…

This section contains details regarding the procedures employed in acquiring and processing the physiological and ambient environment data collected within our extreme environments chamber. The experiment design, sensor based data acquisition and…

We propose a DFIRMM for Ag-IoT as an extended version of our previous study²⁷, and its architecture is represented in Fig. 1. This model guides incident response and forensic investigation teams in making decisions to identify evidence,…

The development process focused on building an accessible, user-friendly platform that addresses the needs of visually impaired students to improve their ability to solve arithmetic problems with missing digits. The solution contains multiple…

An important clarification should be made on the terminology used in this paper. The term ‘reference’ (as in reference electrode) refers to the channel against which correlation and coherence maps are computed. Only in the methodology…

The overall layout of CCE, including the LWSN and other associated units, is shown in Fig. 4. The LWSN consists of n sensor nodes closely spaced for better spatiotemporal correlation. For straight identification, the j^th sensor node is…
