The causes of malalignment in total knee arthroplasty can be categorized into three different groups; 1) Errors in bone cuts 2) Errors in implant fixations, and 3) The method of setting down the cutting guides (1). We would like to announce that more several distal femoral valgus cut errors may occur during total knee replacement.

MIT Abstract. In this paper, we introduce a variant of spectral sparsification, called proba-bilistic (ε, δ)-spectral sparsification. Roughly speaking, it preserves the cut value of any cut (S, S c) with an 1 ± ε multiplicative error and a δ |S| additive error. We show how to produce a probabilistic (ε, δ)-spectral sparsifier with O(n log n/ε 2) edges in time˜O(n/ε 2 δ) time for unweighted undi...

Cheeger cut has recently been shown to provide excellent classification results for two classes. Whereas the classical Cheeger cut favors a 50-50 partition of the graph, we present here an asymmetric variant of the Cheeger cut which favors, for example, a 10-90 partition. This asymmetric Cheeger cut provides a powerful tool for unsupervised multi-class partitioning. We use it in recursive bipar...

In this research paper, we use a normalized graph cut measure as a thresholding principle to separate an object from the background based on the standard S membership function. The implementation of the proposed algorithm known as fuzzy normalized graph cut method. This proposed algorithm compared with the fuzzy entropy method [25], Kittler [11], Rosin [21], Sauvola [23] and Wolf [33] method. M...

This paper presents a solution aimed at enhancing the accuracy of abrasive waterjet cutting (AWJC) for processing carbon-fiber-reinforced polymers (CFRP). Processing CFRP with high and good surface quality in short time is difficult task. One crucial problem occurrence shape errors, overcuts, cut-in cut-out point during process. Shape errors have potential to create mechanical stress concentrat...
