In 1996 an agreement was made between a well-known beverage manufacturer, Super-Cola Taiwan, (SCT) and a small Australian electrical engineering company, Dag-Brücken ASRS Pty Ltd, (DB), to provide an automated storage and retrieval system (ASRS) facility as part of SCT’s production facilities in Asia. Recognising the potential of their innovative and technically advanced design, DB was awarded ...

Conveyor based assembly production lines were first introduced by Ford H. in the 19th Century, in a need for responding to the increasing market capacity then. Today, many challenges are imposed by conveyor lines including unbalanced station workloads, line inflexibility in coping with changes in demand. This paper describes the implementation of discrete event simulation in the improvement of ...

In this paper, problems and application of the computation of false alarm rate (FAR) and threshold for belt conveyor systems are studied. Based on an information system which is developed to meet the requirements on monitoring and fault detection for large scale belt conveyor systems, the probability distribution of model uncertainty is assumed to be known and will be taken into account for the...

INTRODUCTION AND AIMS Knowledge of attention deficit hyperactivity disorder (ADHD) symptoms among patients in opioid maintenance treatment (OMT) is important for treatment optimization and yet limited. We investigated the prevalence of ADHD symptoms, and factors associated with high ADHD symptom burden in a group of Norwegian OMT patients. METHODS We interviewed individuals entering OMT acros...

The flow which constitutes the conveyor belt in the Hamburg large-scale geostrophic ocean general circulation model has been investigated with the help of a particle tracking method. In the region of North Atlantic Deep Water formation a thousand trajectories were calculated backward in time to the point where they upwell from the deep ocean. Both the three-dimensional velocity field and convec...

A new biquadratic universal filter configuration realizing second-order low-pass, band-pass, and high-pass fiters using single current conveyor is proposed. Using this configuration high-pass, low-pass and band-pass fiters can be realized with little modifications. The circuit employs a secondgeneration current conveyor (CCII+), and only four passive components. Since the current conveyor is a ...

To proof low voltage techniques are valid in current conveyor design, Bulk driven and composite transistor (self cascode) techniques are used to get high performance results from CCII in low voltage supply. Conventional operational amplifier circuit from literature was our choice as core of the design. Our Focus with using low voltage techniques is study the frequency characteristics of a CCII ...

This paper describes the design and implementation of a flexible parts feeding system. While flexibility encompasses every part of the workcell design, including hardware and control software, the ability to feed parts in a wide variety of sizes and shapes is crucial. Conventional feeding methods, such as vibratory bowl feeders, are not practical for flexible workcells because of their speciali...

With the advancement of global warming, Arctic sea routes (ASRs) may open for entire year. The ASRs will be far more competitive than they are now, and major international in future. To date, most studies have researched economic feasibility short term from a company’s perspective. help to plan shipping market future, we developed three-stage model simulate trade demand long term. This firstly ...
