The number of inner points excluded in an initial convex hull (ICH) is vital to the efficiency getting the convex hull (CH) in a planar point set. The maximum inscribed circle method proposed recently is effective to remove inner points in ICH. However, limited by density distribution of a planar point set, it does not always work well. Although the affine transformation method can be used, it is still hard to have a better performance. Furthermore, the algorithm mentioned above fails to deal with the exceptional distribution: the gravity centroid (GC) of a planar point set is outside or on the edge formed by the extreme points in ICH. This paper considers how to remove more inner points in ICH when GC is inside of ICH and completely process the case which mentioned above. Further, we presented a complete algorithm architecture: (1) using the ellipse and elasticity ellipse methods (EM and EEM) to remove more inner points in ICH and process the cases: GC is inside or outside of ICH. (2) Using the traditional methods to process the situation: the initial centroid is on the edge in ICH. It is adaptive to more data sets than other algorithms. The experiments under seven distributions show that the proposed method performs better than other traditional algorithms in saving time and space.

This chapter presents some results about groups generated by reflections and the standard metric on a Bruhat-Tits building. It begins with definitions relating to an affine subspace, an affine hyperplane, an affine span, an affine map, and an affine transformation. It then considers a notation stating that the convex closure of a subset a of X is the intersection of all convex sets containing a and another notation that denotes by AGL(X) the group of all affine transformations of X and by Trans(X) the set of all translations of X. It also describes Euclidean spaces and assumes that the real vector space X is of finite dimension n and that d is a Euclidean metric on X. Finally, it discusses Euclidean representations and the standard metric.

Depreciation Methods

Tax Management must be done throughout the company’s activities. In principle, tax management can be done via good tax compliance and minimizing tax burden. The latter can be achieved by transforming non-deductible expenses into deductible expenses. For example, PT Nyambung Teruuusss Tbk. (PT. NT) must change income Tax Art. 21 paid by the company into tax allowance with gross-up method, pooling company's cars at the office instead of letting these cars brought home by the employees, outbound training for employees instead of family gathering, and other methods including converting fringe benefits into allowance. Another method to minimize tax burden is to change depreciation methods into double-declining method instead of straight-line method. With nondeductible transformation method have saved PT NT Rp 5.26 billion of corporate income tax, while depreciation methods transformation is predicted to save the company Rp 735.66 billion for an eightyear period
