INTRODUCTION. MR imaging of the heart and thoracic vessels requires ECG gating to compensate for cardiac motion. Triggering is accomplished by synchronizing the image acquisition pulse sequence to the R-wave of the ECG. However, the magnetic fields within the bore of the scanner can cause artifacts in the ECG waveform which result in gating errors. In addition, small variations in electrode pos...

This paper addresses the problem of path plannrng using a dynamic vehicle model. Previous works which include a basic kinematic model generate paths that are only realistic at very low speed. By considering higher vehicle speed during navigation, the vehicle can significantly deviate from the planned trajectory. Consequently, the planned path becomes unusable for the mission achievement. So, to...

in this research, production possibility and shelf life of frying margarine had analyzed. in order, the test was done in factorial form and totally random method. tested factors were different kinds of margarine (counteractive effect between type of oil in oil phase (canola) and different moisture (16-8-4%) as the first factor and time of keeping margarine as the second factor. in this margarin...
