The Optimized Link State Routing Protocol is developed for Mobile Ad Hoc Network. It operates as a table driven, proactive protocol. The core of the OLSR protocol is the selection of Multipoint Relays (MPRs), used as a flooding mechanism for distributing control traffic messages in the network, and reducing the redundancy in the flooding process. A node in an OLSR network selects its MPR set so...

Foam flooding (or injection of foam) is a common technology to enhance oil recovery. Although the effects of permeability on foam flooding were well studied in many laboratory experiments, little research has been focused on the specificity of low permeability. In this paper, a series of constant-quality nitrogen foam flow experiments were conducted to investigate the effects of permeability on...

This paper presents a simple and robust mechanism, called Change-Point Monitoring (CPM), to detect denial of service (DoS) attacks. The core of CPM is based on the inherent network protocol behaviors, and is an instance of the Sequential Change Point Detection. To make the detection mechanism insensitive to sites and traffic patterns, a non-parametric Cumulative Sum (CUSUM) method is applied, t...

wild plant germplasm possesses useful adaptive strategies. wild plant species, for example, are resistant to biotic and abiotic stress and can be used for reforestation, agriculture, and horticulture. we surveyed the potential of wild pear to resist flooding. we looked at survival, growth, biomass, and several physiological variables. the rootstocks of wild pear are candidates for planting in o...

thick gel-like pellicle enclosing a fluid core. Upon treatment of the vitally stained tissue with hypertonic salt solution, thus simulating fixation shrinkage, these vesicles can be observed to collapse, discharge the fluid vesicle content or elongate forming a pseudoreticulum similar to that exhibited by the Golgi apparatus of the osmicated cell. Desiccation, superimposed upon the shrunken mat...
