OBJECTIVES Angiotensin converting enzyme inhibitors (ACEI) have been shown to decrease aortic growth velocity (AGV) in Marfan syndrome (MFS). We sought to compare the effect of β-blockers and ACEI on AGV in MFS. STUDY DESIGN We retrospectively reviewed all data from all patients with MFS seen at Arkansas Children's Hospital between January 1, 1976 and January 1, 2013. Generalized least square...

Reducing cost of material handling has been a big challenge for companies. Flexible manufacturing system employed automated guided vehicles (AGV) to maintain efficiency and flexibility. This paper presents a new non-linear mathematical programming model to group n machines into N loops, to make an efficient configuration for AGV system in Tandem layout. The model minimizes bot...

PURPOSE To compare 3-year outcomes and complications of the Ahmed FP7 Glaucoma Valve (AGV) (New World Medical, Cucamonga, CA) and the Baerveldt Glaucoma Implant (BGI) 101-350 (Abbott Medical Optics, Abbott Park, IL) for the treatment of refractory glaucoma. DESIGN Multicenter, randomized, controlled clinical trial. PARTICIPANTS A total of 276 patients: 143 in the AGV group and 133 in the BG...

PURPOSE To compare the 5-year outcomes of the Ahmed FP7 Glaucoma Valve (AGV) (New World Medical, Cucamonga, CA) and the Baerveldt 101-350 Glaucoma Implant (BGI) (Abbott Medical Optics, Abbott Park, IL) for the treatment of refractory glaucoma. DESIGN Multicenter, randomized, controlled clinical trial. PARTICIPANTS A total of 276 patients, including 143 in the AGV group and 133 in the BGI gr...

Localization and navigation technology is one of the key technologies for Automated Guided Vehicle (AGV). In this paper we develop an AGV navigation system utilizing commercial Bluetooth GPS. WGS-84 coordinates system is converted to space rectangular coordinate system, which is combined with orientation information, initial position and gesture of AGV can be determined. Experimental result sho...

As a kind of wheeled mobile robot used in intelligent logistics system, AGV is mainly used for automatic material transportation, the precise positioning and path tracking is the assurance of accurate material transportation. In this article, the laser coordinate positioning technology is used to realize accurate positioning for AGV, a new method of target reference point selection is put forwa...

. Object-oriented modelling provides a new point of view to focus a flexible manufacturing system using organized models similar to the Flexible Manufacturing Cell (FMC) presented in this paper which composed by Flexible Manufacture Modules (FMMs) and an automated guided vehicle (AGV). The implemented FMC working with revolution specimens, with predetermined measures length, are composed mainly...

The control, navigation and interaction with the working environment of Automated Guided Vehicles (AGV) are indispensable processes for material handling in a Flexible Manufacturing System(FMS) . In this paper, the prospect of using an optical mouse as an economical yet efficient alternative sensor for AGV navigation and control is depicted. This work emphasizes on the supervision and surveilla...

This paper describes the intelligent Automated Guided Vehicle (AGV) control system using Fuzzy Rule Interpolation (FRI) method. The AGV used in this paper is a virtual vehicle simulated using computer. The purpose of the control system is to control the simulated AGV by moving along the given path towards a goal. Some obstacles can be placed on or near the path to increase the difficulties of t...

OBJECTIVES To evaluate the long-term efficacy of intraocular pressure reduction and complications of Ahmed glaucoma valve (AGV) implantation in children with primary congenital glaucoma. METHODS The medical records of patients with primary congenital glaucoma who underwent AGV implantation with a minimum follow-up of 6 months were reviewed. The primary outcome measure was cumulative probabili...
