This online structured survey has demonstrated the global impact of the COVID‐19 pandemic on vascular services. The majority of centres have documented marked reductions in operating and services provided to vascular patients. In the months during recovery from the resource restrictions imposed during the pandemic peaks, there will be a significant vascular disease burden awaiting surgeons.

Face recognition systems constitute a significant proportion of robotic systems. Learning algorithms such as deep learning and machine learning provide state-of-the-art algorithms with highly improved recognition rates. A majority of these algorithms convert a face image into a feature matrix, holistic or local, matched against all the feature matrixes in gallery for recognition. However, there is...
The 500KV substations are important for power system in Pakistan. They cover large area meeting the power requirement of whole power system. The ground grid system of substation has to be carefully analyzed in order to protect the grid, keep the system functional. A practical 500KV substation is chosen for this purpose i.e. RAWAT Grid Station. The grounding system of substation is studied in detail...
The aim of optimal power flow is to discover an operating point that minimizes the generation cost while satisfying multiple operating constraints. Over the years, several techniques have been introduced to solve this non-linear optimization problem. In this paper, genetic algorithm deploying optimum non-uniform mutation rate and elitism has been used to solve this problem. After implementation of...
