The ORB-SLAM2 based on the constant velocity model is difficult to determine search window of reprojection map points when objects are in variable motion, which leads a false matching, with an inaccurate pose estimation or failed tracking. To address challenge above, new method feature point matching proposed this paper, combines reverse optical flow method. First, extended model, and expanded ...

Under standard Lipschitz conditions, trajectories of systems described by ordinary differential equations are well defined in both forward and reverse time. (The flow map is invertible.) However for hybrid systems, uniqueness of trajectories in forward time does not guarantee flow-map invertibility, allowing non-uniqueness in reverse time. The paper establishes a necessary and sufficient condit...

Reverse engineering of UML sequence diagrams plays an important role in iterative development and in software maintenance. In static analysis for such reverse engineering, an open question is how to map control-flow graphs to the control-flow primitives of the recently-introduced new generation of UML. Our work presents the first algorithm that solves this problem. We also propose transformatio...

Potential risks of genetically modified (GM) crops must be identified before their commercialization, as happens with all new technologies. One of the major concerns is the proper risk assessment of adventitious presence of transgenic material in rice fields due to cross-pollination. Several studies have been conducted in order to quantify pollen-mediated gene flow from transgenic rice (Oryza s...

In this paper, we propose a new model for designing integrated forward/reverse logistics based on pricing policy in direct and indirect sales channel. The proposed model includes producers, disposal center, distributers and final customers. We assumed that the location of final customers is fixed. First, a deterministic mixed integer linear programming model is developed for integrated logistic...

Time-domain representations of the fetal aortopulmonary circulation were carried out in lamb fetuses to study hemodynamic consequences of congenital diaphragmatic hernia (CDH) and the effects of endothelin-receptor antagonist tezosentan (3 mg/45 min). From the isthmic aortic and left pulmonary artery (PA) flows (Q) and isthmic aortic, PA, and left auricle pressures (P) on day 135 in 10 controls...
