Perfect Rings for Which the Converse of Schur’s Lemma Holds
If M is a simple module over a ring R then, by the Schur’s lemma, the endomorphism ring of M is a division ring. However, the converse of this result does not hold in general, even when R is artinian. In this short note, we consider perfect rings for which the converse assertion is true, and we show that these rings are exactly the primary decomposable ones.
متن کاملA Virtual Reality Tooth Drilling Simulator
A virtual teeth drilling system whose basic aim is to be used for the training of dental students in the handling of drilling instruments is presented in this paper. A 3D model of the face and the oral cavity is utilized by the application. This model can be adapted to the characteristics of a specific person and animated. Drilling is performed within the oral cavity, on realistic teeth models ...
متن کاملSome Surfaces of General Type for Which Bloch’s Conjecture Holds
We give many examples of surfaces of general type with pg = 0 for which Bloch’s conjecture holds, for all values of K2 6= 9. Our surfaces are equipped with an involution. Let S be a smooth complex projective surface with pg(S) = 0. Bloch’s conjecture states that the Albanese map A0(S)0 → Alb(S) is an isomorphism, where A0(S)0 is the Chow group of 0-cycles of degree 0 on S. It is known for all s...
متن کاملEvaluating Drilling and Suctioning Technique in a Mastoidectomy Simulator
This paper presents several new metrics related to bone removal and suctioning technique in the context of a mastoidectomy simulator. The expertise with which decisions as to which regions of bone to remove and which to leave intact is evaluated by building a Naïve Bayes classifier using training data from known experts and novices. Since the bone voxel mesh is very large, and many voxels are a...
متن کاملBone drilling haptic interaction for orthopedic surgical simulator
Drilling procedure is widely used in orthopedic surgery to position reduced fractured bones and prosthetic components. However, successful execution of bone drilling requires a high level of dexterity and experience, because the drilling resistance is large and sometimes vibrates violently to difficultly grasp the hand-piece or even break the slender drill. This paper introduces haptic function...
