The crankshaft composite follow crankshaft turning lathes use the following tool system to complete the turning of crankshaft, when crankshaft machining is working, the turret mechanisms processing error and assembly errors will affect the crankshafts processing quality, So it is difficult to control the actual machining accuracy, or it may cause the waste of material. Therefore, in this paper, by analyzing the impact of the rod length errors on the trajectory of the tool tip, the tool tip trajectorys equations can be built. Using MATLAB tools, we can build the tip point trajectory modeling and solve the deviation between the actual tip point and the ideal trajectory, and finally can get the result of rod lengths error on the accuracy of the actual processing, which will provide basis for the design and analysis in future.

AbstractA widely used tool in studying quasi-monoperiodic processes is the O–C diagram. This paper deals with the application of this diagram in minor planet studies. The main difference between our approach and the classical O–C diagram is that we transform the epoch (=time) dependence into the geocentric longitude domain. We outline a rotation modelling using this modified O–C and illustrate the abilities with detailed error analysis. The primary assumption, that the monotonity and the shape of this diagram is (almost) independent of the geometry of the asteroids is discussed and tested. The monotonity enables an unambiguous distinction between the prograde and retrograde rotation, thus the four-fold (or in some cases the two-fold) ambiguities can be avoided. This turned out to be the main advantage of the O–C examination. As an extension to the theoretical work, we present some preliminary results on 1727 Mette based on new CCD observations.

Learning Test

Performance on a German version of the Rey Auditory-Verbal Learning Test (AVLT) was investigated for 64 juvenile patients who were subdivided in 6 clinical groups. In addition to standard evaluation of AVLT protocols which is usually confined to items recalled correctly, an error analysis was performed. Differentiating between total errors (TE), repetition errors (RE), and misnamings (ME), substantial differences between clinical groups could be demonstrated. It is argued that error analysis of verbal memory and learning enriches the understanding of neuropsychological syndromes, and provides additional information for diagnostic and clinical use. Thus, it is possible to gain a more accurate picture so that patients can be appropriately retrained, and research into the functional causes of memory and learning disorders can be intensified.
