in many signal processing applications, an appropriate measure to comparetwo signals plays a fundamental role in both implementing the algorithm andevaluating its performance. several techniques have been introduced in literature assimilarity measures. however, the existing measures are often either impractical forsome applications or they have unsatisfactory results in some other applications....

patients and methods in this retrospective, cross-sectional study, the medical records of all deceased neonates hospitalized in fatemieh hospital of hamadan, during a 5-year period (2006 – 2011) were extracted. a questionnaire including sex, weight, gestational age, time of birth, delivery mode, maternal disease, and leading cause of death was filled out. the information was then analyzed using...

Background and Objectives: Work sampling is a useful technique to characterize how employees allocate their work time to various activities. Given the value of nurses’ time for quality health care delivery, characterization of nursing time distribution may provide useful information for optimal use of nursing staff. The purpose of the present study was to explore time allocatio...

In many signal processing applications, an appropriate measure to compare two signals plays a fundamental role in both implementing the algorithm and evaluating its performance. Several techniques have been introduced in literature as similarity measures. However, the existing measures are often either impractical for some applications or they have unsatisfactory results in some other applicati...

We derive a new generalized imaging condition based on time shifts between source and receiver wavefields. This imaging condition contrasts with other imaging techniques requiring space shifts between the two wavefields. This imaging condition is applicable to both Kirchhoff and wave-equation migrations. The transformation allows us to generate common-image gathers presented as function of eith...
