AIM To evaluate the results of Ahmed glaucoma valve (AGV) in eyes with a failed trabeculectomy. MATERIALS AND METHODS This retrospective study evaluated 61 eyes with a failed trabeculectomy that underwent implantation of an AGV due to uncontrolled intraocular pressure (IOP) on maximal medical therapy. Success was defined as IOP ≤ 21 mm Hg (criterion 1) or 20% reduction in IOP (criterion 2) wi...

En el ámbito industrial se utilizan con frecuencia Vehículos de Guiado Automático (AGV) para transporte mercancía puntual, normalmente sustituyendo a los medios manuales o las cintas transportadoras, así reducir costes operativos y errores humanos. Para aumentar rendimiento estos sistemas industriales que puedan realizar funcionalidades más avanzadas, es fundamental desarrollar modelos orientad...

Automated Guided Vehicle (AGV) merupakan sebuah alat yang berfungsi untuk mendistribusikan barang dari suatu tempat ke lain. Penghubung antar station menggunakan jalur garis berwarna hitam. Robot AGV terdiri atas sensor infra merah sebagai umpan balik PID, mikrokontroler pengolah data serta menjalankan alogaritma PID dan motor DC aktuator. ini bisa diaktifkan smartphone memanfaatkan sinyal blue...

The technology for collaborative robots and the way these technologies are used in current socio-technical work systems rapidly evolving industrial applications. In absence of prescribed safety assessment methods from normative standards, this paper explores capabilities an STPA analysis behaviour robot We applied to a with heavy-load manipulating arm gripper, mounted on AGV-type mobile base. s...

In this paper, we study the design and different methodology of automated guided vehicle (AGV) systems. This paper provides an overview on AGVS technology discusses recent technological developments and describes the formulation to control the traffic inside industrial work space.

We study an automated container terminal in which Automated Guided Vehicles (AGVs) are used to internally transport containers and Automated Stacking Cranes (ASCs) to store and retrieve containers. In designing container terminals, the terminal management has to consider the choice for interrelated AGV and ASC dispatching rules and the layout of the stack. In this paper, we, therefore, examine ...

PURPOSE To present the long-term results of Ahmed glaucoma valve (AGV) implantation. METHODS Consecutive case series of 94 eyes with AGV implantation over 7 years. Temporary tube ligation with C3F8 gas fill was used in high-risk eyes (group G&L) and compared with standard implantation in both phakic (group A) and pseudophakic/aphakic eyes (group B). Success was intraocular pressure (IOP) of 6...

This contribution presents a novel approach to address the scheduling of resource-constrained flexible manufacturing systems (FMSs). It deals with several critical features that are present in many FMS environments in an integrated way. The proposal consists in a constraint programming (CP) formulation that simultaneously takes into account the following sub-problems: (i) machine loading, (ii) ...

As a typical transportation tool in the intelligent manufacturing system, Automatic Guided Vehicle (AGV) plays an indispensable role automatic production process of workshop. Therefore, integrating AGV resources into scheduling has become research hotspot. For problem flexible job shop adopting segmented AGV, dual-resource optimization mathematical model machine tools and AGVs is established by...
