As the construction of smart grids is in full swing, the number of secondary equipment is also increasing, resulting in an explosive growth of power big data, which is related to the safe and stable operation of power systems.During the operation of the secondary equipment, a large amount of short text data of faults and defects are accumulated, an
Systematics of Old World Odontacolus Kieffer s.l. (Hymenoptera, Platygastridae s.l.): parasitoids of spider eggs
The genera Odontacolus Kieffer and Cyphacolus Priesner are among the most distinctive platygastroid wasps because of their laterally compressed metasomal horn; however, their generic status has remained unclear.We present a morphological phylogenetic analysis comprising all 38 Old World and four Neotropical Odontacolus species and 13 Cyphacolus spe

Access to potable water and proper sanitation remains a pressing global issue, particularly in developing regions like Nigeria, where waterborne diseases are prevalent due to inadequate water and sanitation facilities.Consequently, the paper assesses household hygiene, potable water sources, and sanitation practices in IkpobaOkha Local Government A
IMAGE MOSAIC ALGORITHM BASED ON PCA-ORB FEATURE MATCHING
In the process of image stitching, the ORB (Oriented FAST and Rotated BRIEF) algorithm lacks the characteristics of scale invariance and high mismatch rate.A principal component invariant feature transform (PCA-ORB, Principal Component Analysis- Oriented) is proposed.FAST and Rotated BRIEF) image stitching method.Firstly, the ORB algorithm Lift is
