We present a review on the electronic design of chaotic oscillators. Multi-scroll chaotic oscillators are listed according to their electronic implementations. A 3-scrolls oscillator is analyzed from its mathematical description, and designed with current-feedback operational amplifiers. Finally, we list the integrated realizations, and discuss key points for future research on the design of mu...

A simple scheme for rail to rail op-amp operation is introduced. The input stage uses complementary differential pairs but only one pair is active at a time. It uses very compact control circuitry. Experimental verification is provided from a test chip prototype in 0.5 μm CMOS technology.

This study explores the relationship between operational efficiencyand profitability and growth in the US life Insurance industry, and provides a frameworkfor linking operating performance and financial success.Earnings and growth have particular importance to life insurance companies;earnings and capital determine the viability of the insurer, while growth is paramount toth...

Although the importance of the external IT environment has been recognized in the literature, there has been little effort to conceptualize the theoretical dimensions of this construct and develop operational indicators to measure it. Our research addresses this gap and seeks to develop the theoretical dimensions and operational measures for external IT environment and empirically validate them...

The evaluation on nuclear power plant operational safety performance had great significance on whether the nuclear power plant operated safely or not. Currently the academic literatures on nuclear power plant operational safety performance are rare. Improved Fuzzy evaluation model which introduce confidence level had been used into the evaluation of nuclear power plant operational safety perfor...

The purpose of the analysis machines for planting seedlings produced by various manufacturers was to determine best ratio balance prices and labor costs machine seedlings. It established that highest competitiveness coefficient obtained a 4-row with carousel apparatus.

The paper presents a simulation tool for automated interactions between insurance companies and their clients during the travel insurance buying process. Insurance deal evaluation model using price and insured risks has been developed based on the study of the Latvian insurance market. The proposed model is used together with well-known agent auction protocols, thus providing a multi-agent nego...

Social criteria have been proposed to evaluate the sustainability of operational initiatives in the process industry through an integrated Life Cycle Management (LCM) approach. Indicators for these social criteria are subsequently introduced. The calculation of the indicators follows conventional LCIA methods, and specifically the distance-to-target approach for normalisation, whereby a societa...

EXECUTIVE SUMMARY This paper introduces a framework developed for the waste management sector supported by Performance Indicators. It was designed in order to be coherent and articulate and to enable full integration of its information. These indicators proved to be a useful management tool. This framework includes 167 performance indicators (PI) divided into two types of information: 58 Contex...
