Quay crane allocation is one of the most important scheduling plans in the container terminal. A large of production data is stored in the database of the terminal. This paper utilizes the method of data mining to analyze the problem of quay crane allocation by using these data. From the mining, valuable information has been gotten from the database. The paper chooses the fuzzy cmeans cluster a...

Currently, a variety of the MBONE video tools provide video conferencing capabilities on different platforms and with a variety of compression algorithms. However, most of these tools lack the ability to interact with other media agents that might be used during a conferencing session. Such interaction is required, for example, for achieving lip synchronisation between audio and video streams o...

Advances in information technology have triggered changes in the way work is done at VDTs. Traditional patterns of office work have also been changing accordingly, with mobile work being a typical example. We conducted a series of studies to examine the current state of VDT work and identify any new occupational safety and health issues. Our results suggest that new patterns of office work, if ...

This paper introduces a new computational organizational analysis and design model, called the Virtual Team Alliance (VTA), that builds on the Virtual Design Team (VDT) (Jin and Levitt, 1996). VTA extends Galbraith’s framework implemented in VDT in two ways: (1) it addresses less routine tasks with some flexibility in how they are performed, and (2) it treats project participants as teleologica...

Wide-spread provision of broadband multimedia services requires a powerful signaling system, which does not exist yet. Future signaling will have to support calls with several participants, several connections and heterogeneous terminals. This paper introduces a new framework for an overall signaling system designed to meet the requirements of multimedia services. An object-oriented call model ...

The market for application performance products and services can be divided into three segments: measurement, control and extension. Measurement is the art of looking into an application delivery system of servers, networks and terminals to see how well it functions and determine how to make it function better. Control vendors help deliver the best performance possible given the innate limitati...

The important distinction between parameterized specifications and specifications of parameterized programs has been originally pointed out in [12]. An important difference concerns the objects which the two kinds of parameterization allow one to reuse. A parameterized specification, “PSP”, e.g., of stacks parameterized by elements, Stack(El), allows one, under some conditions, to instantiate t...

In an actual measurement of random fluctuations, e.g., sound, light and electromagnetic (abbr., EM) fluctuation waves, the measured data are very often processed in a level-quantized form at discrete time intervals. In this paper, a unified explicit expression for the probability function with level-quantized random variables for an arbitrary random fluctuation wave is theoretically derived in ...

experimental economics, continuous double auction, equilibration, market dynamics, price stability We present results from four experiments in which a simple continuous double auction market is operated on a network of computer terminals. Our experiments are based on those reported by Smith & Williams in a 1983 paper, but with one significant procedural difference: unlike in other experimental ...

The Simple Landside Aggregate Model (SLAM) is a model for estimating capacity and delays in airport passenger terminals. SLAM is designed to answer “what if” questions about alternative configurations of the various processing and holding facilities in a terminal. It consists of a network of modules, one for each facility of the terminal. These modules are based on a set of quite simple mathema...
