"Survival data consist of a single event for each population unit, namely, end of life, which is modeled with a life distribution. In contrast, many applications involve repeated-events data, where a unit may accumulate any number of events over time. Examples include the number and cost of repairs of products, the number and treatment costs of recurrent disease episodes in patients, and the number of childbirths to statisticians. This applied book provides practitioners with basic nonparametric methods for such data, particularly the plot of the estimate of the population mean cumulative function (MCF), which yields most of the information sought.Recurrent Events Data Analysis for Product Repairs, Disease Recurrences, and Other Applications is the first book to present a simple, unified theory that includes data on costs or other "values" of discrete events, not just the number of events. It surveys computer programs that calculate and plot the MCF estimate with confidence limits, shows their output, and explains how to interpret such plots. Many such calculations can be easily done with a pocket calculator or spreadsheet program. Also, the book introduces basic Poisson and Cox regression models and parametric models, including homogeneous and nonhomogeneous Poisson processes and renewal processes."

"This book contains articles from scientists and experts from 10 countries. They illuminate the width of application of this technology and the quality of problems solved using discrete event simulation. Practical applications of simulation dominate in the present book."

"Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 102-106Pendulum appliance is one of intra oral appliances to distalize molars for correction of class II molar relationship or space gaining in the maxillary arch. Its major advantages are no need to depend on patient compliance, ease of fabrication, and better patient acceptance. In this case, 22 years old female patients with class ll division 2 malloclussion were treated with pendulum appliance for unilateral distalation of the maxillary molar teeth. Pendulum can distalize second molar until 4 mm in 4 months and continues to distalize first molar in 3 month. Nevertheless, relaps 2mm happens during anterior retraction. This case has shown that pendulum is an effective and reliable appliance for distalizing maxillary molars. However, molar distalization is at the expense of moderate anchorage loss during anteior retraction, which could possibly be reduced if the anchor unit is adequately reinforced."
