This paper contributes to the characterization of synchronous models of distributed computing using topological techniques. We consider a generic synchronous model with send-omission failures and use a topological structure corresponding to a bounded number of rounds of the model. We observe some nice properties of the structure and derive from these properties necessary and sufficient conditions to solve consensus in this model.

On-line real-time monitoring of marine and operational exhaust stacks and process streams can play a critical role in providing safe, environmentally sound operation of marine and industrial processes using volatile organic species. Monitoring systems are needed that are inexpensive and powerful to be effective. It has been demonstrated that two independent responses, wave velocity and wave attenuation can be obtained from surface acoustic wave devices coated with viscoelastic polymers. This output technique enables identification and concentration determination of isolated species with a single sensor. This paper discusses the development of the sensor devices and the basis of portable acoustic wave sensor systems (which are being used) to monitor volatile organic compounds from marine and industrial chemical processes. Furthermore, on-line monitoring of spray cleaning processes has been effective in quantifying how emissions can be decreased based on substituting solvents, optimizing worker protocols, and utilizing new spray nozzle configurations.

The author examines the classical notion of persona (the role adopted by the writer) as a term useful in analyzing technical documents. It isolates rhetorical strategies that are components of the user-friendly persona and briefly speculates on the usefulness of those strategies given the interactive relationship between the writer and the audience.

Where is system architecture heading? The special interest group on Computer and systems Architecture (Fachausschuss Rechner- und Systemarchitektur) of the German computer and information technology associations GI and ITG a- ed this question and discussed it during two Future Workshops in 2002. The result in a nutshell: Everything will change but everything else will remain. Future systems technologies will build on a mature basis of silicon and IC technology,onwell-understoodprogramminglanguagesandsoftwareengineering techniques, and on well-established operating systems and middleware concepts. Newer and still exotic but exciting technologies like quantum computing and DNA processing are to be watched closely but they will not be mainstream in the next decade. Although there will be considerable progress in these basic technologies, is there any major trend which uni?es these diverse developments? There is a common denominator – according to the result of the two - ture Workshops – which marks a new quality. The challenge for future systems technologies lies in the mastering of complexity. Rigid and in?exible systems, built under a strict top-down regime, have reached the limits of manageable complexity, as has become obvious by the recent failure of several large-scale projects. Nature is the most complex system we know, and she has solved the problem somehow. We just haven’t understood exactly how nature does it. But it is clear that systems designed by nature, like an anthill or a beehive or a swarm of birds or a city, are di?erent from today’s technical systems that have beendesignedbyengineersandcomputerscientists.
