Recently, some nondestructive methods for the assessment of albumen freshness were developed. Among others, visible near-infrared transmission spectroscopy and low-resolution proton nuclear magnetic resonance (LR (1)H NMR) measurements were proposed. This study was performed to evaluate the potential of the combined measurement of visible near-infrared transmission spectroscopy and LR (1)H NMR ...

We propose, DONUT, a real-time producers/consumers model, as an abstract model for developing real-time scheduling and resource allocation techniques in the domain of real-time network management. Under this model, we consider not only the availability but also the freshness of the consumed resources (i.e., “donuts”). Given a resource type <, two quantitative measures are defined to evaluate th...

This paper studies the notion of “freshness” that often occurs in the meta-theory of computer science languages involving various kinds of names. Nominal Equational Logic is an extension of ordinary equational logic with assertions about the freshness of names. It is shown to be both sound and complete for the support interpretation of freshness and equality provided by the Gabbay-Pitts nominal...

today the usage of some compounds as indicator, can be checked changes of the food quality without opening the package. the most important indicators are indicates that show the level of product quality and freshness. freshness and temperature - time reagents reflect on extension of the product quality. indicators show the quality of the product, by physical and chemical changes which will be l...

Most data warehouse deployments are not prepared to scale automatically, although some applications have large or increasing requirements concerning data volume, processing times, data rates, freshness and need for fast responses. The solution is to use parallel architectures and mechanisms to speed-up data integration and to handle fresh data efficiently. Those parallel approaches should scale...

Caching is an effective mechanism for reducing bandwidth usage and alleviating server load. However, the use of caching entails a compromise between content freshness and refresh cost. An excessive refresh allows a high degree of content freshness at a greater cost of system resource. Conversely, a deficient refresh inhibits content freshness but saves the cost of resource usages. To address th...

A general method is described for formally specifying and reasoning about distributed systems with any desired degree of immediacy for revoking authentica-tion. To effect revocation, 'authenticating entities' impose freshness constraints on credentials or authenticated statements made by trusted intermediaries. If fresh statements are not presented, then the authentica-tion is questionable. Fre...

We propose an Edge-write architecture which performs eager update propagation for update requests for the corresponding secondary server, whereas it lazily propagates updates from other secondary servers. Our architecture resolves consistency problems caused by read/update decoupling in the conventional lazy update propagation-based system. It also improves overall scalability by alleviating th...

This research focuses on a pervasive but largely unexamined product attribute—freshness date—to shed light on how and why its influence on the consumption of perishable products changes with product ownership. Drawing on recent research on the endowment effect, we demonstrate that even when the differential costs implicit in ownership are controlled for, consumers are more likely to actually co...

Abstract: To estimate the freshness of beef meat the dielectric measurements were carried out on the twenty five samples. Capacitance (C) and conductance (G) were measured using LCZ meter over a frequency range from 10 kHz to 1 MHz. The measured values were used to calculate permittivity and conductivity of beef at various time intervals (2, 4, 10, 20, 30, 40 and 50 days) during storage. The ef...
