A new echo canceller for discrete multitone (DMT) systems is presented where each used tone has its own per tone echo canceller (PT-EC) in addition to a per tone equalizer (PTEQ) [1, 2]. This enables us to optimize the Signal-to-Noise Ratio (SNR) for each tone separately by solving a Minimum Mean Square Error (MMSE) problem for each tone. Simulation results confirm improved performance over tim...

Ovarian hyperstimulation dyndrome(OHSS) is one of the most serious complications of ovulation indution in infertile women particularly in poly cystic ovare (PCO).in recent years,in association with the increasing frequency of assisted reproductive technology(ART) usage and significant improvements in the treatment of infertility,this iatrogenic phenomenon is more prevalent.the aim of this clini...

We have used a remifentanil-based anaesthetic for patients undergoing major abdominal surgery who would normally have gone to the intensive care unit in this hospital. Avoiding intensive care unit admission was considered an advantage as a shortage of intensive care unit beds was leading to the cancellation of operations. We first used remifentanil as part of a safety and efficacy study. The ai...

Relationship conflict has detrimental effects, and scholars advise avoiding these conflicts. However, little is known about the emotional experience of relationship conflict and the intrapersonal consequences of conflict avoidance. In a field study of a long-term healthcare organization, we developed and tested a model examining the emotional experience of relationship conflict, and, in particu...

AdaBoost is a well known, effective technique for increasing the accuracy of learning algorithms. However, it has the potential to overfit the training set because it focuses on misclassified examples, which may be noisy. We demonstrate that overfitting in AdaBoost can be alleviated in a time-efficient manner using a combination of dagging and validation sets. The training set is partitioned in...

The performance of Time Warp parallel discrete event simulators can be a ected by the cancellation strategy used to send anti-messages. Under aggressive cancellation, anti-message generation occurs immediately after a straggler message is detected. This results in quick termination of potentially incorrect computations (event processing) when out-of-order event processing occurs. In contrast, l...

Background: Human fertility has been declined all over the world. Advanced women’s age is one of the most important factors in determining the success of reproduction and ageing has negative impact on ART outcome and advanced female age decreases the chance of live birth rates achieved using ART, especially after 40 years of age. The purpose of this study was to evaluate ART outcomes regarding ...
