todays, in many modern applications, we search for frequent and repeating patterns in the analyzed data sets. in this search, we look for patterns that frequently appear in data set and mark them as frequent patterns to enable users to make decisions based on these discoveries. most algorithms presented in the context of data stream mining and frequent pattern detection, work either on uncertai...

In this paper, we introduce a deterministic fluid model and two stochastic traffic models for wireless networks. The setting is a highway with multiple entrances and exits. Vehicles are classified as calling or non-calling, depending on whether they have calls in progress. The deterministic model ignores the behavior of individual vehicles and treats them as a continuous fluid, whereas the stoc...

Background: Modern subject-based philosophy, in which everything reduces to the whole, reduces to the Other to I, or emanates it from the realm of knowledge, ignores the differences, currently cannot answer to ethics. Levinas, as a philosopher who has a concern about the “Other", believes that there is no subject that needs to be known, and the other is "Self" in advance and is touched rather t...

This report presents the use of independent contact and non-graspable regions to generate the grasp space for 2D and 3D discrete objects. The grasp space is constructed via a sampling method, which provides samples of force-closure or non force-closure grasps, used to compute regions of the graspable or non-graspable space, respectively. The method provides a reliable procedure for an efficient...

This paper discusses the stability of 2D frictionless grasps and combining stability of frictional and frictionless grasps from the viewpoint of potential energy method. In many works related to the frictionless grasp, each finger is replaced by one directional virtual spring along the normal at the contact point. However, this condition is not accurate, because the frictionless condition does ...

The synthesis of force-closure grasps on three–dimensional (3-D) objects is a fundamental issue in robotic grasping and dextrous manipulation. In this paper, a numerical force-closure test is developed based on the concept of distance. With some mild and realistic assumptions, the proposed test criterion is differentiable almost everywhere and its derivative can be calculated exactly. On this b...
