Regular crack inspection of tunnels is essential to guarantee their safe operation.At present, the manual detection method is time-consuming, subjective and even dangerous, while the automatic detection method is relatively inaccurate.Detecting tunnel cracks is a challenging task since cracks are tiny, and there are many noise patterns in the tunne
The laterally positioned flap (LPF) has been proposed as a promising treatment for isolated gingival recessions (GRs) in mandibular incisors.Several modifications have been proposed to reduce the risk of gingival recession (GR) at the donor tooth site.Therefore, the aim of this was to describe a modified one-stage procedure of performing the LPF as
This paper provides an analytical evaluation of the performance of proportional fair (PF) scheduling in Orthogonal Frequency-Division Multiple Access (OFDMA) wireless systems.OFDMA represents a promising multiple access scheme for transmission over wireless channels, as it combines the orthogonal frequency division multiplexing (OFDM) modulation an
ABSTRACT Objective To characterize the temporal trend of epidemiological indicators of leprosy Casual Shoes in the State of Amapá.Method Time series study, carried out in the Notifiable Diseases Information System.The indicators analyzed were: annual detection rate of new cases, detection rate of new cases in the population from 0 to 14 years old,
This paper presents a novel multicast routing protocol for wireless sensor networks, named Multicast tree protocol with Pruning and Energy Balancing (MPEB) to disseminate data through a layered multicast tree with high-efficiency and low-power consumption.With pruning algorithm and energy balancing algorithm, MPEB can save energy and balance load.P
