That is teachers should adopt effective methods to correct the errors and make use of the feedback to adjust teaching method and content according to the weakness and difficulties of the learners.

Based on the analysis of the frequent error types in STL data model,corresponding methods of automatic correction for each kind of error proposed is put forward,and a software system in Visual C++6.0 to automatically correct the errors above put forward is developed.

Quaternion compensation algorithm for attitude correction of SINS is proposed using closed loop Kalman filter (KF) method that can real-time correct the errors of inertial instrument, compensate quaternion, position and velocity.

The observed quantity of the SINS/OD is the velocity's differences between SINS and OD,and the SINS/OD also adopts a closed kalman filter to estimate and correct the errors.

Following the principles of methodological individualism, we show how behavioral explanations supported by data and theory from the neurosciences can be used to correct the errors of reificationist thinking in the social sciences.

A microprocessor is used to process the effects on the thermocouple of the additional current, without dismantling it from its operating location, in order to correct the errors of the thermoelectric thermometer.

The conclusion concerning Coulomb blockade thermometry is more optimistic and two-fold: (1) One can now correct the errors due to bias heating in a satisfactory manner based on known material properties and the size of the metal films in the sensor.

These theories correct the errors induced by the adhesion forces on contact parameters.

We made a large effort to correct the errors and to complete the structural descriptions.

This paper points out that the formula for transmission efficiencies of planetary gearings depend mainly on the direction of meshing power flow of their respective inverted mechanisms.Based upon this idea, the authors correct the errors in the formula for planetary gearings of type 3K given by. Kudriatsev [1][2] and discussed the errors in the article "A Simplified Method" [3].

Based on the materials of 50 Han male adult cadavers collected in South China in recent years, we have calculated the constants (a) and the regression coefficients (6) for estimating the stature by long bones as well as the coefficients of correlation (r) between the length of long bones and the stature. The value of the correlation coefficients varies within 0.516-0.913. This indicates that the degree of correlation is high. On this basis we have also calculated ten regression formulae by which the stature...

Based on the materials of 50 Han male adult cadavers collected in South China in recent years, we have calculated the constants (a) and the regression coefficients (6) for estimating the stature by long bones as well as the coefficients of correlation (r) between the length of long bones and the stature. The value of the correlation coefficients varies within 0.516-0.913. This indicates that the degree of correlation is high. On this basis we have also calculated ten regression formulae by which the stature can be estimated. The correction value 0.6 mm×(age-30) is used to correct the error caused by age.

This paper presents a terrain-aided navigation system which can correct the errors of inertial or other guidance systems and improve the navigation accuracy.This system is composed of a Kalmaa filter,a radar altimeter and a digitized terrain map.Based on the stored terrain data and the state predicted currently by the navigation system,it is possible to calculate the predicted clearance and slope of terrain in real-time.The predicted clearance is compared with the actual clearance measured by radar altimeter...

This paper presents a terrain-aided navigation system which can correct the errors of inertial or other guidance systems and improve the navigation accuracy.This system is composed of a Kalmaa filter,a radar altimeter and a digitized terrain map.Based on the stored terrain data and the state predicted currently by the navigation system,it is possible to calculate the predicted clearance and slope of terrain in real-time.The predicted clearance is compared with the actual clearance measured by radar altimeter in the Kalman filter and the error estimates of the navigation system are calculated according to the terrain slope.Then,the error estimates are fed back to update the navigation system.The process described above is iterated so that the terrain-aided navigation system is updated almost con-tinuosly.The stochatic linearization technique is utilized to obtain the linearized measurement equation.The terrain-aided system can reach a high accuracy for vehicle location.The final estimated errors of position are approximately as follows:here,σn2 is the variance of measurement noise,σsx2 and σsy2 are the variances of terrain slopes in x and y direction respectively,N is total number of updates.The results of computer simulation indicate that the location accuracy of the terrain-aided system can reach magnitude of about ten meters for a typical hilly region.
