This paper surveys the main difficulties involved with the quantitative measurement of operational risk and proposes simulation methods as a practical solution for obtaining the aggregate loss distribution. An example that calculates both expected and unexpected losses as well as operational risk VAR is provided.

Tehran is one of the densely populated metropolises located in earthquake-prone regions. Tehran, the population of which surpasses 8 million people, is the most populated area in Iran. There are historical evidences confirming that catastrophic earthquakes have destroyed the city in past years. In the present paper, our study covers all parts of Tehran because there is the potential of signific...

introduction radiographs provide unique information about the status of periodontium and permanent records of condition of bone throughout the course of the disease. interproximal images record the distance between the cementoenamel junction and the crest of the interradicular alveolar bone, more accurately. the aim of this study was to investigate the effect of different vertical angles of x-r...

background severe birth asphyxia (apgar < 7 at the 5th minute of birth) is recognized as a hearing loss risk factor by the joint committee on infant hearing (jcih). about half of the newborns with hearing loss do not indicate any sign and risk factor at birth. accordingly, the joint committee recommended performance of hearing screening test in 2000, especially for babies born with risk factors...

background radiographs play an integral role in the assessment of periodontal disease. in recent years, advent of digital imaging has revolutionized radiology in dentistry. patients and methods in this diagnostic accuracy study, 48 inter proximal surfaces were evaluated in eight patients. these patients had alveolar bone loss in anterior regions because of periodontitis. intraoral (parallel per...
