Perhaps you should try some spelling variations:
imputation techniques » implantation technique, augmentation techniques, segmentation techniques
simulation technique » inhalation technique, implantation technique, mitigation techniques
code simulation » 3d simulation, based simulation, carlo simulation
based code » based anode
based two » based tool, based co
