A project work was done within the time frame of January to December 2004 in Islamic University of Technology, Gazipur, Bangladesh. The main objective of this work is to design a Flexible Material Handling System (FMS) that can automatically synchronize its speed as per requirement. The system is designed for two types of conveyor system where the speed of the horizontal conveyor belt will be r...

Three-dimensional (3D) ac electro-osmotic (ACEO) pumps have recently been developed that are much faster and more robust than previous planar designs. The basic idea is to create a "fluid conveyor belt" by placing opposing ACEO slip velocities at different heights. Current designs involve electrodes with electroplated steps, whose heights have been optimized in simulations and experiments. Here...

This paper presents a novel quadrature sinusoidal oscillator using second-generation current conveyor transconductance amplifier as an active building block. The proposed circuit employs only a single second-generation current conveyor transconductance amplifier, four passive components. The proposed circuit offers the advantages of independent control of the condition of oscillation and freque...

ABSTRACT: Floating inductor circuits using minimum number of passive elements namely two resistors and one capacitor is reviewed in this paper. All the circuits considered in this paper are floating. Previously reported non-floating circuits are modified to be floating and new floating circuits are introduced as well. The active elements used in this paper are floating conveyor building blocks ...

This paper proposes an automated method for segregating and counting the different colored pencils by non-contact method. The proposed work is carried out in LabVIEW platform based on the image processing techniques. This work consists of two parts, firstly classification of pencils and secondly counting the number of pencils. The proposed work is implemented on a conveyor running continuously,...

Composable Conveyors expose fundamental new problems that must be addressed as the nation transforms its advanced manufacturing infrastructure. Unanticipated fluctuations in workloads caused by the increasingly open and interconnected advanced manufacturing systems makes it significantly challenging to appropriately configure and adapt the operating parameters of conveyor systems that are deplo...

Process improvement is a major requirement for a production manager who aims to reduce cost and achieve the target throughput. To achieve a target throughput, load balancing is commonly conducted, and resource investment is examined such as adoption of automation machine or hiring of new employee In this study, the impact of the waiting time caused by a moving conveyor is investigated based on ...

background although heller myotomy is one of the most effective treatments for achalasia, it may be associated with early or late symptom relapse in some patients. therefore, additional treatment is required to achieve better control of symptoms. aim : to evaluate the safety and efficacy of pneumatic balloon dilation (pbd) in patients with symptom relapse after heller myotomy. methods thirty si...

Pneumatic servo systems are applied in several industrial applications and have also been studied extensively for the purposes of compensating the nonlinearity of pneumatic servo systems and improving the controllability with robust control. In their control system design, the transfer function of a pneumatic servo system has been a third-order time lag system, based on the assumption that serv...

BACKGROUND/AIM Pneumatic caisson engineering has been developed for large civil engineering constructions. Because of complaints of blurred vision by personnel working in pneumatic caissons, the development of myopia was suspected. The aim of this study was to determine the cause of the blurred vision and the mechanism underlying the changes. METHODS 12 caisson workers underwent a complete op...
