The Ethernet standard is a standard solution for interconnecting industrial devices despite its intrinsic drawbacks, particularly its nondeterministic medium access method. Many Ethernet-based commercial solutions available (COTS Components Off the Shelves) on the market guarantee time performance. This means that user selection of one particular solution is a critical decision, but the choice ...

Process adjustment, also known as process targeting, is one of the classical problems in the field of quality control and production economics. In the process adjustment problem, it is assumed that process parameters are variables and the aim is to determine these parameters such that certain economic criteria are optimally satisfied. The aim of this paper is to determine the optimal process ad...

in this paper, a new combined power and refrigeration cycle is proposed, which combines the rankin power cycle and the ejector refrigeration cycle. this combined cycle produces both power output and refrigeration output simultaneously. this cycle is driven by the flue gas of gas turbines, industrial waste heats, solar energy and geothermal energy. an exergy analysis is performed to guide the th...

This paper presents an approach to analytically determine the most energy efficient toolpath strategy in mechanical machining. This was achieved by evaluating the electrical energy requirement of the NC codes generated for the zag, zigzag, and rectangular contour toolpath strategies. The analytical method was validated by performing pocket milling on AISI 1018 steel with the considered toolpath...

Increasingly organizations compete based on time. As a result, cycle-time reduction is a key agenda for organizations interested in achieving increased customer service and reduced cost. With improved cycle time, organizations can often eliminate or reduce inventory while expanding customer service offerings. The purpose of this tutorial is to present the fundamental concepts of cycle time redu...

istorically, many information systems (IS) organizations focused their attention on the quick delivery of systems rather than assuring that the software had been rigorously tested. Now, however, organizations are recognizing that it is more effective and less expensive to test for errors earlier in the systems development process (Parker, 1991). This “frontending” helps to decrease cycle time (...

The multicluster architecture that we introduce o ers a decentralized, dynamically-scheduled architecture, in which the register les, dispatch queue, and functional units of the architecture are distributed across multiple clusters, and each cluster is assigned a subset of the architectural registers. The motivation for the multicluster architecture is to reduce the clock cycle time, relative t...

By the end of 2009, the Great Recession that began in December 2007 had doubled the unemployment rate, reduced stock prices by 25 percent, and lowered housing prices by 10 percent. The advent of the monthly American Time Use Survey (ATUS) in 2003 facilitates a detailed examination of trends in time allocations following these large macroeconomic shocks to the prices of time and assets. Previous...

Executive Summary If cycle times are to be continuously improved upon, organizations must look beyond the process-oriented areas in the organization to other more non-traditional areas. In addition, to uncover opportunities that have gone unnoticed, different perspectives on cycle time reduction and a willingness to try different approaches need to be adopted. In this article, cooperative learn...
