Since Berrou, Glavieux and Thitimajshima published their landmark paper in 1993, different modified BCJR MAP algorithms have appeared in the literature. The existence of a relatively large number of similar but different modified BCJR MAP algorithms, derived using the Markov chain properties of convolutional codes, naturally leads to the following questions. What is the relationship among the d...

Localization is considered as one of the most significant research issues in Wireless Sensor Network (WSN). The objective of localization is to determine the physical co-ordinates of sensor nodes distributed over the sensing field. Location information plays a vital role for coverage, deployment of sensor nodes, routing and target tracking applications. Initially, the localization of sensor nod...

OBJECTIVES To assess the performance of screening for preeclampsia (PE) by mean arterial pressure (MAP) at 11-13 and at 20-24 weeks' gestation. METHODS MAP was measured at 11-13 and 20-24 weeks in 17,383 singleton pregnancies, including 70 with early PE, requiring delivery <34 weeks' gestation, 143 with preterm PE, delivering <37 weeks and 537 with total PE. MAP was expressed as multiple of t...
