A 7th order polyphase G/sub -m/C IF filter with automatic frequency tuning, implemented in a 0.35/spl mu/m CMOS process, is presented. The filter has a center frequency of 3MHz and a passband of 1MHz. The image band rejection is higher than 57dB, the stop band attenuation is at least 40dB. The in-band spurious free dynamic range is around 53dB. On-chip automatic frequency tuning provides more than

With increased market competition and advances in modern manufacturing technologies, requirements on customer orders and manufacturing conditions have become more diversified. This paper addresses a dynamic production planning problem for a steel plate fabrication plant with practical flexibility of both customers and manufacturing, such as steel slab-plate matching rules, plate substitution optio

Quality requirements complement functional requirements with information on the target quality levels of software functions or emergent system quality aspects. In release planning the allocation of development effort in further investments into product enhancements, new or enhanced functions are competing with quality improvements for limited resources. When setting balanced quality targets for de

The Sixth Sense of PR-Experts? An Expert-Novice-Comparison of PR-Problem-Solving and Implications for Public Relations-Pedagogy

Whistle-blowing can serve as a powerful mechanism helping policy-makers and other stakeholders recognize ethical misconduct and other types of wrongdoing in autonomous public agencies. This mechanism is of particular importance in major public sector reforms, such as agency mergers, when it may be difficult to secure continuity in the quality of organizational processes. Yet, we know little of wha

Over the past decade scholars in the humanities and social sciences have increasingly been pressed to demonstrate the manner in which their research is “useful” to society while simultaneously, funding for their research has been more tightly tied to bibliometric measurements that prioritize high-brow scholarship geared towards publish results in “leading” international peer-review journals. In ma

This thesis deals with tools for operational improvement of supply chain performance. The work was aimed at providing knowledge for supply chain developers and practitioners, and identifying and developing tools for improved performance in a supply chain. The investigation was part of a project financed by the European Commission called "Industrial Supply Chain Optimizer" (ISCO). The thesis consis

Computers are increasingly used for implementing controlalgorithms in safety-critical embedded applications, such asengine control, braking control and flight surfacecontrol. Addressing the consequent coupling of control performancewith computer related errors, this paper develops a composite computerdependability/control theory methodology for analyzing the effectsdata errors have on control syst

Abstract in Undetermined This work tackles the problem of interferometric phase estimation in the presence of layover by using nonuniform multibaseline interferometric synthetic aperture radar systems. The effects of nonuniform sampling on Fourier-based and superresolution spectral estimation methods are investigated. The impact on both the spectral properties and on the interferometric phase esti

The Working Group III Special Report on Renewable Energy Sources and Climate Change Mitigation (SRREN) presents an assessment of the literature on the scientific, technological, environmental, economic and social aspects of the contribution of six renewable energy (RE) sources to the mitigation of climate change. It is intended to provide policy relevant information to governments, intergovernment

The possibility of reducing the transient times at grade changes in paper production and machine start-ups on the paper machines has highlighted the need for increased knowledge of the steam supply system. Models in this area have been presented in previous work and it is of interest to compare these models with each other and evaluate them against experimental data. This paper reports on the resu
