We develop a mathematical model for adsorption based on averaging the flow around, and diffusion inside, adsorbent particles in a column. The model involves three coupled partial differential equations for the contaminant concentration both in the carrier fluid and within the particle as well as the adsorption rate. The adsorption rate is modelled using the Sips equation, which is suitable for describing both physical and chemical adsorption mechanisms. Non-dimensionalisation is used to determine the controlling parameter groups as well as to determine negligible terms and so reduce the system complexity. The inclusion of intra-particle diffusion introduces new dimensionless parameters to …

Clustering is an effective statistical data analysis technique; it has several applications, including data mining, pattern recognition, image analysis, bioinformatics, and machine learning. Clustering helps to partition data into groups of objects with distinct characteristics. Most of the methods for clustering use manually selected parameters to find the clusters from the dataset. Consequently, it can be very challenging and time-consuming to extract the optimal parameters for clustering a dataset. Moreover, some clustering methods are inadequate for locating clusters in high-dimensional data. To address these concerns systematically, this paper introduces a novel selection-free clustering technique named data point positioning analysis (DPPA). …

This paper presents the empirical liquidity study of Islamic fixed-income securities during 2020-2021. Using bid-ask and Z-spread metrics we demonstrate that the apogee of both, liquidity and credit stresses in international sukuk market is reached in early April 2020. Contrasting results for non-Islamic fixed-income instruments, we show that sukuk credit spreads recover to pre-Covid levels faster than their bid-ask spreads. However, we find that the share of liquidity component in the yield spread of sukuks always remains below 1%, revealing that Covid-19 does not worsen in relative terms the economic attractiveness of this financing channel for Shariah-concerned entities and investors.
