This chapter addresses the dimensional synthesis of parallel kinematics machines. A multiobjective optimization problem is proposed in order to determine optimum structural and geometric parameters of parallel manipulators. The proposed approach is applied to the optimum design of a three-degree-of-freedom planar parallel manipulator in order to minimize the mass of the mechanism in motion and to...
The complex design of moulds and dies based upon complicated features and usage of harder materials is a continuous challenge for the development of manufacturing technology for these parts. In this paper we present an algorithm for handling this challenge as well as its implementation by using numerical techniques for the calculation of CNC tool-path. The algorithm consists of multiple stages and...
Childhood obesity has reached epidemic proportions: Some 4.7 million youths between 6 and 17 years of age are overweight or obese. The number of over-weight youths (11%) has more than doubled over the past 30 years. Obesity has links with disease such as diabetes, heart disease, sleep disorders and some forms of cancers. Developing and maintaining a healthy lifestyle are essential for the prevention...
Minutiae based approach is most widely used for fingerprint matching. Minutiae can be extracted either directly from gray-scaled image or from a thinned image. During matching, finding an exact match depends on the best matched minutiae pairs from both images. For matching stage, different kinds of features are extracted from extracted minutiae. The structure of some features allows us to have rotation...
