Context: The key for effective problem prevention is detecting the causes of a problem that has occurred. Root cause analysis (RCA) is a structured investigation of the problem to identify which underlying causes need to be fixed. The RCA method consists of three steps: target problem detection, root cause detection, and corrective action innovation. Its results can help with process improvemen...

The windowed synchronous averaging (WSA) is widely utilized for planetary structures. However, it cannot be applied the fault detection of structure in industrial robot rotate vector (RV) reducer. usually works within a specified angle range, which causes RV reducer rotates incompletely. To address this issue, an compensation local fitting scheme proposed. detect localized planet gear reducer, ...

Enterococci are usually encountered and predominate in oral infections, especially those associated with dental root canal infections of necrotic pulp periodontitis. This study aimed to detect identify Enterococcus faecium isolated from infected canals, using polymerase chain reaction ( PCR). Thirty samples were collected patients pulp, endodontic treatment failure, attending the Conservative T...

the net analyte signal standard addition method was used for simultaneous spectrophotometric determination of sertraline and fluoxetine in pharmaceutical preparations. the method combines the advantages of the standard addition method with the net analyte signal concept to enable the extraction of information about an analyte from the spectra of multi-component mixtures. this method uses full s...

invasive cervical resorption is a condition that affects the root surface area below the epithelial attachment. multiple treatment modalities are advocated, involving exposure of the invasive defect, removal of the granulation tissue and sealing with various restorative materials. this report demonstrates conservative treatment of a patient presenting with peri-apical periodontitis in upper rig...

Purpose This study compared the diagnostic accuracy of cone-beam computed tomography (CBCT) scans obtained with 2 CBCT systems with high- and low-resolution modes for the detection of root perforations in endodontically treated mandibular molars. Materials and Methods The root canals of 72 mandibular molars were cleaned and shaped. Perforations measuring 0.2, 0.3, and 0.4 mm in diameter were ...

-Digital image processing relies heavily on detection of various objects. Detection of geometric objects like lines and circles helps image understanding. In this paper, an improved version of Hough transform for circle detection in digital images is presented. Hierarchical Hough transform has been modified to achieve better computational efficiency. An important property of square root of inte...
