Operational excellence is generally known as a management system integrated across critical functions that is geared towards continually improving operational performance. Functional areas such as health, environment and safety, quality and human resources are the focus of many corporate-wide operational excellence programs. Operational excellence also focuses on improving areas such as custome...

To assess operational performance of air traffic control sector, a multivariate detection index system consisting of 5 variables and 17 indicators is presented, which includes operational trafficability, operational complexity, operational safety, operational efficiency, and air traffic controller workload. An improved comprehensive evaluation method, is designed for the assessment by optimizin...

Maintenance workshop integrated in the job-shop system is required in order to maintain the production machines, to ensure the continuity of service and thus to contribute to the improvement of the availability. The objective is to propose a maintenance workshop where all corrective maintenance activities are centralized. When a failed equipment from the production workshop occurs, it is sent t...

Current mirrors are core structures for almost all analog mode circuits and are integral part of a signal processing elements like op amps. The performance of analog structures largely depends on their characteristics. In this paper we present some of the current mirror circuits and analyze their performances, so that one can choose a suitable current mirror for a particular application.

This paper proposes a module of a high gain and high swing 2-stage amplifier. It is suitable for building a general operational amplifier in a modular fashion with various optional performances. The proposed module alone offers opened-loop voltage gain up to 124 dB and GBW of 10 MHz without loading conditions. To assemble a 124 dB voltage gain operational amplifier with load driving capacity of...

We use a special operational semantics which drives us in inferring quantitative measures on system describing cryptographic protocols. The transitions of the system carry enhanced labels. We assign rates to transitions by only looking at these labels. The rates reflect the distributed architecture running applications and the use of possibly different cryptosystems. We then map transition syst...

This paper presents a computer-aided design tool, IPRAIL, which automatically retargets existing analog layouts for technology migration and new specifications. The reuse-based methodology adopted in IPRAIL utilizes expert designer knowledge embedded in analog layouts. IPRAIL automatically extracts analog circuit and layout intellectual properties as templates, incorporates new technology desig...
