Action perception is selective in that observers attend to and encode certain dimensions of action over others. But how flexible is action perception in its selection of perceptual information? One possibility is that observers consistently attend to particular dimensions of action over others across different contexts. Another possibility, tested here, is that observers flexibly vary their att...

As the world container volumes are soaring, container terminals form a very important chain in the global transportation network. It is a generally accepted view that the modelling of the dynamic and stochastic nature of the container terminal systems using analytical or closed form models is a complicated process and the use of such models is very limited. Hence, this paper presents a simulati...

Container terminals are designed to provide support for the continuous changes in container ships. The most common schemes used for dock management are based on discrete and continuous locations. In view of the steadily growing trend in increasing container ship size, more flexible berth allocation planning is mandatory. The consideration of continuous location in the container terminal is a go...

Software containers present an effective mechanism for decoupling cross-cutting concerns in software. System-wide concerns such as persistence, transaction management, security, fault masking, etc., are implemented as container services. While a lot of effort has been expended in developing effective container implementations, specifications for software containers are largely presented in info...

In the last four decades the container, as an essential part of a unit-load-concept, has scored a great success in international sea freight transportation. With increasing containerization the number of seaport container terminals and competition has increased considerably. One of the success factors of a terminal is related to the time in port for container vessels and the transshipment rates...

The major characteristics of ERP (Enterprise Resource Planning) are an enterprise-wide system that covers all the business functions and information resources, integrated database, built-in best industry practice, packaged software and open architecture. ERP enables reduction of system development time, flexibility, standardization of workflow and effective business planning capability. ERP is ...

Conformal Killing vectors (CKVs) preserve the spacetime metric up to a factor. Homothetic vectors and Killing vectors are special cases of CKVs. Classification of some classes of spacetimes on the basis of CKVs give interesting results showing how homothetic and Killing vectors which form subsets of the set of CKVs can be recovered as a result of the above classification. ∗On leave from: Centre...

Computational tools for normal mode analysis, which are widely used in physics and materials science problems, are designed here in a single package called NMscatt (Normal Modes & scattering) that allows arbitrarily large systems to be handled. The package allows inelastic neutron and X-ray scattering observables to be calculated, allowing comparison with experimental data produced at large sca...

OBJECTIVE This study aimed to determine if occupational exposure to whole-body vibration is associated with cervical intervertebral disc herniation among container truck drivers. METHODS We conducted a walk-through survey among container truck drivers and unexposed workers. We also measured the vibration hazard of the container truck over the driver's back and seat when the driver was loading...
