Nowadays, one of the main problems encountered in minimally invasive surgery and telesurgery is the detection of arteries in tissue. In this study, for the first time, tactile detection of an artery in tissue and distinguishing it from the tumor has been modeled by finite element method. In this modeling, three 2D models of tissue have been created: tissue, tissue including a tumor, and tissue ...

In the last two decades, interest in graphene has grown extensively due to its extraordinary properties and potential for various applications such as sensing communication. However, is intrinsically a semimetal with zero bandgap, which considerably delays use where suitable bandgap required. this context, quasi-one-dimensional counterparts known nanoribbons (GNRs) have demonstrated sizeable ba...

The conventional calibration methods based on a perspective camera model are not suitable for the underground with two-layer glasses, which is specially designed explosion proof and dust removal in coal mine. Underground modeling algorithms urgently needed to improve precision reliability of visual measurement systems. This article presents novel geometrically driven algorithm boom-type roadhea...

Purpose This paper aims to model a three-dimensional twisted geometry of pair studied in an electrostatic approximation using only two-dimensional (2D) finite elements. Design/methodology/approach The proposed method is based on the reformulation weak formulation electrostatics problem deal with geometries 2D. Findings change coordinates and enables faster computational time as well high accura...

We present an interactive modeling system for flower composition that supports seamless transformation from an initial sketch to a detailed three-dimensional (3D) model. To begin, the user quickly sketches the overall appearance of the desired model as a collection of two-dimensional (2D) strokes on hierarchical billboards. Then the user iteratively replaces the coarse sketch with a detailed 3D...

We are investigating the design of machine vision algorithms for real time inspection of filter components for quality assurance. Filter components are rigid 3D objects with predefined geometry so that a good deal of knowledge can be incorporated into the system design. However, while the objective is to reason about 3D structure, current machine vision techniques only allow the acquisition of ...
