Collaborative filtering (CF) approaches, which provide recommendations based on ratings or purchase history, perform well for users and items with sufficient interactions.However, CF approaches suffer from the cold-start problem for users and items with few ratings.Hybrid recommender systems that combine collaborative filtering and content-based ap
The reliability analysis of vertically integrated protection devices is crucial for designing International Electrotechnical Commission (IEC) 61850-based substations.This paper presents the hardware architecture of a four-in- one vertically integrated device and the information transmission path of each function based on the functional information
A massive periodontal destruction can affect the root canal (RC) system and potentially expose the pulpo-dentinal complex to opportunistic bacteria.Streptococcus mutans is a major pathogen of human caries and periodontal diseases, and its virulence mostly resides in the ability to adhere to collagen and form biofilms, due to collagen-binding protei
For training young pilots.Flight simulators enhance the safety measures, as the risk factor of severe injuries are eliminated since the training is now synthetic.However, flight simulators also require large space, large budget and does have many high end requirements, which are to be met in order to make the simulator respond and perform identical
ABSTRACTUrban land change and transportation infrastructure development often interact and collectively lead to significant socioeconomic and biophysical impacts.Here, we performed a systematic review to identify how urban land change modeling studies account for transportation infrastructure.We found that less than one-fifth of urban gold ps5 cont
