Purpose: To examine the safety and efficacy of simultaneous Ahmed glaucoma valve (AGV) implantation with intravitreal and intracameral injection of bevacizumab (IVB and ICB) in patients with refractory acute neovascular glaucoma (NVG) with very high intraocular pressure (IOP) and active neovascularization of the iris (NVI) and/or the angle (NVA) Methods: In a prospective interventional study, p...

This research examines the feasibility of using a field-based approach, within the multi-agent system (MAS) paradigm, to achieve transport assignment in an automatic guided vehicle (AGV) system. In a field-based approach, transports emit fields into the environment. The AGV’s behavior consists of continuously combining received fields and following the gradient of these combined fields. This wi...

PURPOSE To investigate the immediate and long-term outcomes of Ahmed glaucoma valve (AGV) implantation with silicone tube ligation and removable external stents. METHODS This retrospective non-comparative study investigated the outcomes of AGV implantation with silicone tube ligation and removable external stents in 95 eyes (90 patients) with at least 12 months of postoperative follow-up. Qua...

Hierarchical reinforcement learning (HRL) is the study of mechanisms for exploiting the structure of tasks in order to learn more quickly. By decomposing tasks into subtasks, fully or partially specified subtask solutions can be reused in solving tasks at higher levels of abstraction. The theory of semi-Markov decision processes provides a theoretical basis for HRL. Several variant representati...

In this paper, the robot with three wheels is implement and its motion is controlled . two of robot’s wheels are activated by DC motors. The main PID controllers are implemented with a Field Programmable Gate Array(FPGA) for independent robot movement . a FPGA controller communicate with a PC with PCI card(PLX9052) so that the movement of wheels can be displayed on the monitor through PCI card ...

This paper aims the development of autonomous obstacle avoidance algorithm for automated guided vehicle with a Kinect sensor. To do this task, the followings are executed. Firstly, depth data is obtained from the Kinect sensor, and the mean filter approach is developed to filter out noises. Secondly, Otsu and U-V parallax based method is designed to identify background and obstacles. Finally, A...

The objective of this paper is to propose a scheduling problem for multiple automated guided vehicles (AGVs) in a manufacturing system. Considering the due date of AGVs requiring for material handling among shops in a job shop layout, their earliness and tardiness are significant in satisfying the expected cycle time and from an economic view point. Earliness results in AGVs waiting and tardine...

Abstract With the development of intralogistics technology in factories, multi-AGV scheduling is still an important problem that needs to be solved by control system. Aiming at path planning and automated guided vehicle (AGV) factory loading unloading work, this paper designs a two-way dual map construction method suitable for factory, introduces different weight right path, uses “simulated roa...

Due to poor predictability of resources and difficulty in perception task execution status, traditional Automatic Guide Vehicle (AGV) scheduling systems need a lot extra time the charging process. To solve this problem, digital twin-based dynamic AGV (DTDAS) method is proposed, including four functions, namely knowledge support system, model, optimization, simulation. With features virtual real...
