Introduction: Blood group, clotting time (CT) and bleeding (BT) are vital haematological parameters that tested prior to any surgery. groups associated with various diseases blood group "O" linked nose bleeds. The aim of this study is evaluate the association between CT BT find differences in gender among these parameters. Study Design: A cross-sectional observational study. Place Duration: In ...

ultra-short pulse is a promising technology for achieving ultra-high data rate transmission which is required to follow the increased demand of data transport over an optical communication system. therefore, the propagation of such type of pulses and the effects that it may suffer during its transmission through an optical waveguide has received a great deal of attention in the recent years. we...

This paper presents a newly proposed asynchronous time difference of arrival (A-TDOA) positioning system. Two major challenges for accurate location finding in indoor environments are the fine time resolution and high accuracy time synchronization. This paper proposes a new positioning method that resolves the time synchronization difficulty by measuring the time difference of arrival at a sing...
