Manufacturing enterprises are facing a competitive challenge. This paper proposes the use of a value chain based approach to support the modelling and simulation of manufacturing enterprise processes. The aim is to help experts to make relevant decisions on product design and/or product manufacturing process planning. This decision tool is based on the value chain modelling, by considering the ...

Due to the proliferation of social media platforms, digital photo sharing has emerged as a new way of establishing chronology of events and reminiscing forgotten experiences. The growing trend of presenting visual content using timelines or shared photo streams offers new possibilities to social media applications. In this paper, a novel interface for visualisation and sharing of multiple photo...

Most of the digital circuits are categorized into the synchronous circuit which uses a clock signal to alter its internal state such that a digital signal is latched by a flip-flop in the timing specified by a clock signal. Therefore, even if a digital signal suffers from ”hazard” in between two consecutive raising edges of a clock signal, a correct signal is successfully latched if the signal ...

The applications envisioned for sensor networks require collaborative execution of a distributed task amongst a large set of sensor nodes. This is realized by exchanging messages that are time-stamped using the local clocks on the nodes. Therefore, time synchronization becomes an indispensable piece of infrastructure in such systems. We propose a design of synchronous clock using digital tune m...

It has become clear in the last few years that there is a trend towards integrated digital services. P d e l to the development of public Integrated Services Digital Network (ISDN) is service integration in the local area (e.g. a campus, a building, an aircraft). The types of services to be integrated depend very much on the specific local environment. However, applications tend to generate dat...

In a synchronous digital system, the clock signal is used to define a time reference for the movement of data within that system. Because this function is vital to the operation of a synchronous system, much attention has been given to the characteristics of these clock signals and the networks used in their distribution. Clock signals are often regarded as simple control signals; however, thes...

This research uses the analytical hierarchy process (AHP) to analyze the key factors in evaluating and screening managers of the intellectual property rights speciality in Taiwan, related to industry. Industry can utilize the key factors of human resource management to provide self-growth and obtain competitive advantage opportunities for expanding the global market share. This research summari...

A membership service for a synchronous distributed computer system is described. The system is assumed to be composed of groups in which a relatively frequent message exchange occurs. A hierarchy of connected groups constitutes a connected network. The membership service protocol reeects this hierarchical structure. The protocol tolerates timing, omission and crash failures. Time-bounds are spe...

This paper presents a pipelined architecture for the hierarchical block-matching motion estimation algorithm (HBMA). The hierarchical style leads enormous computation and complex data flow between hierarchy levels. Each stage of the proposed architecture consists of a systolic array for block-matching and an interpolation unit for bilinear interpolation. The interpolation unit regulates also th...

We describe a process algebraic approach to the semantics of replicated systems. We extend a subset of CCS with a replication operator to model systems with replicated synchronous majority voting. Based on an operational semantics, we deene a bisimulation semantics. As the bisimulation semantics does not characterise fault tolerance we deene preorders which introduces a hierarchy of faulty proc...
