The aim of this research was to study S-ovalbumin as a reference index for the freshness of commercial shell eggs in terms of equivalent egg age. The S-ovalbumin content, yolk index, albumen pH, and Haugh units were determined at the storage temperature of 25 and 37°C, respectively, using 85 fresh-laid eggs. A correlation analysis showed a high correlation coefficient of S-ovalbumin content to ...

Abstract We consider the use of a database cluster with lazy replication. In this context, controlling the quality of replicated data based on users’ requirements is important to improve performance. However, existing approaches are limited to a particular aspect of data quality. In this paper, we propose a general model of data quality which makes the difference between “freshness” and “validi...

Reasoning about atoms (names) is difficult. The last decade has seen the development of numerous novel techniques. For equational reasoning, Clouston and Pitts introduced Nominal Equational Logic (NEL), which provides judgements of equality and freshness of atoms. Just as Equational Logic (EL) can be enriched with function types to yield the lambda-calculus (LC), we introduce NLC by enriching N...

Quality of Service (QoS) and Quality of Data (QoD) are the two major dimensions for evaluating any query processing system. In the context of the new data stream management stystems (DSMSs), multi-query scheduling has been exploited to improve QoS. In this paper, we are proposing to exploit scheduling to improve QoD. Specifically, we are presenting a new policy for scheduling multiple continuou...

This document is a slightly edited and expanded version of a presentation made at an Interwise seminar held on the 20th of April 2010. The topic of the seminar was the sensory evaluation of the freshness of fish as applied in quality control and quality assurance in commerce, the grading of fish for regulatory purposes, and in studies of properties of fish and the handling and processing of fis...

Both response time and content freshness are essential to e-commerce applications on the Web. One option to achieve good response time is to build a high performance Web site by deploying the state of art IT infrastructures with large network and server capacities. With such a system architecture, freshness of the content delivered is limited by the network latency since when users receive the ...

In this paper, we introduce a physical Internet architecture for fresh food distribution networks with the goal of meeting the key challenges of maximizing the freshness of the delivered product and minimizing waste. The physical Internet (PI) architecture is based on the fundamental assumptions of infrastructure sharing among various parties, standardized addressing of all entities and modular...

Many network services and protocols can work correctly only when freshness of messages sent between participants is assured and when the protocol parties’ internal clocks are adjusted. In this paper we present a novel, secure and fast procedure which can be used to ensure data freshness and clock synchronization between two communicating parties. Next, we show how this solution can be used in o...

We present a logic that can express properties of freshness, secrecy, structure,and behavior of concurrent systems. In addition to standard logical and tempo-ral operators, our logic includes spatial operations corresponding to composition,local name restriction, and a primitive fresh name quantifier. Properties can alsobe defined by recursion; a central aim of this paper is...

Data freshness has been identified as one of the most important data quality attributes in information systems. This importance increases especially in the context of systems that integrate a large set of autonomous data sources. In this paper we describe a quality evaluation framework which allows evaluation of data freshness in different architectural contexts. We also show how this quality f...
