In the modern era of a growing population, it is arduous for humans to monitor every aspect of sports, events occurring around us, and scenarios or conditions. This recognition of different types of sports and events has increasingly incorporated the use of machine learning and artificial intelligence. This research focuses on detecting and recognizing events in sequential photos characterized by several factors, including the size, location, and position of people’s body parts in those pictures, and the influence around those people. Common approaches utilized, here are feature descriptors such as mSER (maximally Stable Extremal Regions), SIFT (Scale-Invariant Feature Transform), and DOF (degree of freedom) between the joint points are applied to the skeleton points. moreover, for the same purposes, other features such as BRISK (Binary Robust Invariant Scalable Keypoints), ORB (Oriented FAST and Rotated BRIEF), and HOG (Histogram of Oriented Gradients) are applied on full body or silhouettes. The integration of these techniques increases the discriminative nature of characteristics retrieved in the identification process of the event, hence improving the efficiency and reliability of the entire procedure. These extracted features are passed to the early fusion and DBscan for feature fusion and optimization. Then deep belief, network is employed for recognition. Experimental results demonstrate a separate experiment’s detection average recognition rate of 87% in the HmDB51 video database and 89% in the YouTube database, showing a better perspective than the current methods in sports and event identification. © 2024 The Authors.

The paper discusses the design, fabrication and the execution of the cladding supported by steel trusses and curtain wall of a sports club. The cladding and the curtain walls were subjected to a wind load of 1.2 Kpa considering basic wind speed of 25 m/s as per the project specifications. The first part of the paper deals with the cladding work of the canopy that consist of a 4 mm thick aluminium composite panels supported by steel trusses extended from the main structure. Two types of steel trusses were provided, the main truss connected to the space truss, whereas the intermediate truss connected to channels. Both trusses were spaced at 2.5 m centre to centre. These trusses were fabricated at factory and transported to the site for installation. The second part of the paper is related to the curtain wall design having maximum mullion spacing of 2 m, considered as worst scenario for the design calculations. The maximum mullion height was 5.55 m, adopted in the calculations with bottom and top pinned connection. The Technal system was adopted for the design of mullions and transoms. Design was carried out using numerical modeling with CSI SAP2000 for cladding and its supporting structures. The bracket was realized and checked for the corresponding induced forces. All the structural systems were found safe according to different acceptance criterion.
