Problem statement: Data availability and consistency are foremost issues in Mobile Ad hoc Networks due to the absence of permanent infrastructure. Cooperative caching addresses the data availability issue through coordinating the mobile nodes and sharing the cache copies among them. In the meantime, the mobile node must ensure the staleness of cache copies. The consistency maintenance resolves ...

Strong replica consistency models ensure that the data delivered by a replica always includes the latest updates, although this may result in poor response times. On the other hand, weak replica consistency models provide quicker access to information, but do not usually provide guarantees about the degree of staleness in the data they deliver. In order to support emerging distributed applicati...

A practical concern for Active Learning (AL) is the amount of time human experts must wait for the next instance to label. We propose a method for eliminating this wait time independent of specific learning and scoring algorithms by making scores always available for all instances, using old (stale) scores when necessary. The time during which the expert is annotating is used to train models an...

Client/Server based network management models involve the transmission of large amount of management data towards the centralized management station for processing. The staleness of gathered data (due to network latency involved) and probable error in the selection of management task being carried over (owing to the staleness of data) reduces the reliability of such management applications. In ...

Identifying documents that contain timely and vital information for an entity of interest, a task known as vital filtering, has become increasingly important with the availability of large document collections. To efficiently filter such large text corpora in a streaming manner, we need to compactly represent previously observed entity contexts, and quickly estimate whether a new document conta...

The article uses a comprehensive approach to instrumental control of the parameters texture crumb bakery products: hardness, hardness index, elasticity, strength, cohesion, as well amount mechanical energy expended during deformation sample. Measured indicators allow you evaluate degree staleness and rate products storage. use analyzer “Strukturometr ST-2” makes it possible crumb, its strength ...

Bread is a particularly important staple food. It can be thus improved using different prebiotics like inulin and resistant starch. Food diets with sufficient prebiotic content can trigger the growth of the remaining microorganisms in the digestive system. These microorganisms are essential for human health. In this study, the effect of different levels of inulin and resistant starch (at levels...

In this paper we introduce a cross-layer mechanism to enhance the effectiveness of link-state routing protocols by providing a localized estimate of the validity of a given route. Accurate predictions of route staleness result in less packet loss by selecting alternative paths before primary path failures. We present a proof of concept implementation that utilizes shared location and velocity i...

There are numerous approaches towards quantifying the performance of NoSQL datastores with respect to dimensions that are notoriously hard to capture such as staleness or consistency in general. Many of these approaches, though, are built on assumptions regarding the underlying infrastructure or the test scenario and may lead to invalid results, if those assumptions do not hold. As a consequenc...
