Annotating a video database requires an intensive, time consuming and error prone human effort. However, this is a mandatory task to efficiently analyze multimedia contents. We propose an new selection strategy for active learning methods to minimize human effort in labeling a large database of video sequences. Formally, active learning is a process where new unlabeled samples are iteratively s...

Usually, in monitoring schemes the nominal value of the process parameter is assumed known. However, this assumption is violated owing to costly sampling and lack of data particularly in healthcare systems. On the other hand, applying a fixed control limit for the risk-adjusted Bernoulli chart causes to a variable in-control average run length performance for patient populations with dissimilar...

To solve the problem that all row signals use the same reconstruction algorithm, a type of Bayesian compressive sensing based on importance models is proposed, which reconstructs more important signals firstly even if losing some unimportant signals. Compared to Bayesian compressive sensing whose performances is not well when sampling ratio is lower, the proposed algorithms can improve reconstr...

Background: Non-technical skills are interpersonal and cognitive skills involved in safe performance and preventingadverse events during surgery. it is necessary to dominate the non-technical skills to ensure patient safety. This studyhas aimed to assess the validity and reliability of Oxford Non-technical skills 2 system (Oxford NOTECHS 2) in Iran andto evaluate surgical teams’ non-technical s...

Introduction: Coverage of bone grafts is very important in reconstructive surgery. In edentulous alveolar ridges this coverage is particularly important for supporting dental prostheses. Here we present the case of a patient with a large deficient maxillary anterior region that was reconstructed with a bilateral palatal submucosal periosteal connective tissue flap: a soft tissue reserve for up...

BACKGROUND The recent push for the publication of individual surgeon outcomes underpins public interest in safer surgery. Conventional, retrospective assessment of surgical performance without continuous monitoring may lead to delays in identifying poor performance or recognition of practices that lead to be better than expected performance. DISCUSSION The variable life adjusted display (VLAD...

Team performance is increasingly recognised as an essential foundation of good surgical care and a determinant of good surgical outcome. To understand team performance and to develop team training, reliable and valid measures of team performance are necessary. Currently there is no firm consensus on how to measure teamwork, partly because of a lack of empirical data to validate measures. The in...

BACKGROUND Observational learning plays an important role in surgical skills training, following the traditional model of learning from expertise. Recent findings have, however, highlighted the benefit of observing not only expert performance but also error-strewn performance. The aim of this study was to determine which model (novice vs. expert) would lead to the greatest benefits when learnin...
