This paper analyzed the implementational aspects of the contourlet filter bank (or the pyramidal directional filter bank (PDFB)), and considered its application in image coding.First, details of the binary tree-structured directional filter bank (DFB) are presented, including a modification to minimize the phase delay factor and necessary steps for
In this paper, different optimization algorithms are introduced to solve the security-constrained optimal power flow between two connected regions, applying two control modes, namely the centralized and decentralized modes.Traditionally, the decentralized control, i.e., each power system controls its variables regardless of the boundary buses, is t
Monuments of spiritual and material culture of Lacrosse Sticks the Kievan Rus state, later periods of national history show that the general principles of Christian monasticism became known here at the same time as the first information about Christianity itself - first spontaneously, spontaneously, through the Greek colonies of Crimea, trade route
Step counting is an effective method to assess the activity level of grazing sheep.However, existing step-counting algorithms have limited adaptability to sheep walking patterns and fail to eliminate false step counts caused by abnormal behaviors.Therefore, this study proposed a step-counting Tick Sprays algorithm based on behavior classification d
The common hippopotamus (Hippopotamus amphibius) is one of the most endangered mega herbivore in Africa.Although the human-hippo conflict (HHC) is currently escalating due to habitat loss, little is known about the scope of the conflict and potential mitigation measures.From 2021 to 2022, the extent of HHC, the perception of local inhabitants towar
