Information Freshness Optimization in Real-time Network Applications
… be as fresh as possible. In order to measure the freshness of information, a new metric, called the Age-of-Information (AoI) is proposed. AoI is defined as the time elapsed since the generation time of the freshest delivered update. This metric is influenced by both the inter-arrival time and the …

Information Freshness for Monitoring and Control over Wireless Networks
… we study the optimization of general information freshness metrics in wireless networks, with the goal of applying our theoretical results to problems in real-time monitoring and control. We make contributions in three directions. First, we consider the optimization of general cost functions of …

Optimizing Random Access for Information Freshness in Spatially Distributed Wireless Networks
We analyze Age of Information (AoI) in wireless networks where nodes use a spatially adaptive random access scheme to send status updates to a central base station. We show that the set of achievable AoI in this setting is convex, and design policies to minimize weighted sum, min-max, and …

Information Freshness: How To Achieve It and Its Impact On Low- Latency Autonomous Systems
… state for making better control decisions. This freshness of information is not the same as maximizing the throughput or minimizing the delay. While ideally throughput can be maximized by sending data as fast as possible, this may saturate the receiver resulting in queuing, contention, and other …

Multi-echelon inventory optimization for fresh produce
For fresh produce, the product freshness is a key value to end consumers. Retailers try to maximize product freshness at retail stores while maintaining high product availability. Fresh produce that is close to the end of its life cycle will either be scrapped or be sold at a much lower price. With …

Efficient trusted cloud storage using parallel, pipelined hardware
… One major security concern is the integrity and freshness of data stored on the cloud, that is, whether a storage provider can guarantee that the data received by its clients is always correct and up-to-date. Recent studies have focused on data integrity and freshness guarantees. However, systems …

Mass balance modeling of polychlorinated biphenyls in the Lower Duwamish Waterway
… There are four unknown state variables: freshness, suspended sediment concentration, dissolved phase total PCB concentration, and sorbed phase total PCB concentration. The sole freshness source was the Green River and the freshness sink was the flushing at the downstream mouth. PCBs exist …

Intelligent management for next generation communication systems - communication systems policies for delivering fresh information
… has been proposed to measure and evaluate the freshness of information. Afterwards, a new metric was proposed, named Peak AoI (PA), which represents the worst-case AoI. PA is defined as the maximum time elapsed since the preceding piece of information was generated. The PA metric has a simpler …

The welfare and quality of farmed salmonids at harvest.
… A short-term fast was shown to increase fish freshness in rainbow trout. Killing/ stunning method caused a variable response in both salmonid species, which responded in a similar manner. There was less evidence of muscle activity in fish that were instantly stunned, by electricity (trout) or …
