Mitigation of power outages in Rwanda
, 2022 Power outages in Rwanda severely affected most of the Western and Northern grids of Rwanda in 2018, 2019, and 2020. This paper studied the causes and mechanism of power outages and developed the methods and techniques to mitigate the power outages. Two operational elucidations such as a balanced steady state control system and an optimal overcurrent ...

Institutional Diversity in Banking and Economic Complexity
International Journal of Finance &Economics, EarlyView.ABSTRACT In this paper, we test whether institutional diversity in banking systems is beneficial to economic complexity, using data for Italian provinces in the period 1998–2017. We compute different indexes that consider diversity from an ownership, institutional, business model and competition point of view and find that higher diversity has a ...

Elevator dynamic monitoring and early warning system based on machine learning algorithm
IET Networks, EarlyView., 2022 In order to monitor and warn the elevator dynamics, in this work, the machine learning algorithm is introduced, and the particle swarm algorithm is used to perfect the model. The model is optimised, and the experimental comparison shows that the optimisation of the model parameters can further improve the accuracy of the elevator load prediction. Then,

Institutional Fragility and E‐Business Adoption: A Study of SMEs in a Conflict‐Affected Economy
Strategic Change, EarlyView.ABSTRACT This study examines e‐business adoption among SMEs in Yemen, a conflict‐affected and institutionally fragile economy. Drawing on a mixed‐methods design, it combines Partial Least Squares Structural Equation Modelling (PLS‐SEM) with qualitative interviews to analyse how war and firm size moderate the effects of key adoption drivers and barriers.
