Quality control in an unreliable world
A cell and its world of molecular machines and organelles is complex—and imperfect, full of small errors and looming catastrophes. It is challenged by stresses, environmental insults and general entropy, but works remarkably well. One reason for this is the existence of quality control. Quality control acts at the level of the important macromolecules, proteins, RNA and DNA, as well as at the o...
متن کاملConstructing dependable certainty grids from unreliable sensor data
Measurements from sensors as they are used for robotic grid map applications typically show behavior like degradation or discalibration over time, which affects the quality of the generated maps. This paper presents two novel algorithms for the generation of certainty grids dealing with this behavior. The first algorithm named Fault-Tolerant Certainty Grid (FTCG) performs voting over multiple s...
متن کاملPreparing Semantic Agents for an Unsuspecting and Unreliable World
Semantic web-enabled agents offer tremendous promise for enabling automated coordination and negotiation amongst diverse participants. Ideally, a user should be able to quickly instruct his personal agent to achieve some goal, e.g., to schedule a meeting so that at least one representative of each division of the company would attend. This agent would then negotiate with the agents of all the i...
متن کاملCost Certainty and Time Certainty: an International Investigation
