The ability to quickly evaluate network protocols or infrastructure shapes on real-life scale simulations is a key factor for network researchers work. Since multi-core systems are now widely available and installed, doing multithreading parallelism is a simple but potentially efficient optimization for simulators performance, which may also be implemented so that the parallelism is completely ...

We describe here some recent developments in mesh adaption for compressible viscous inviscid ow simulation. One of the most challenging task is to capture eeciently thin layers such as boundary layers, mixing layers. Two important issues, the coupling between mesh and ow, and the use of at elements for stretching are considered in the case of deformation mesh systems. RESUME : On pr esente une ...

Background and Objectives: Production and consumption of freshly-cut fruits have been increased in recent decades.  One of the major problems in storage of freshly-cut fruits, the color change, is a result of the oxidative reactions of phenolic compounds by polyphenol oxidases. Various treatments such as coating and refrigeration are used to improve quality and shelf-life of the fresh-cut fruit...

The Romanian hamster Mesocricetus newtoni is endemic to South-Eastern Romania (Dobruja region) and North-Eastern Bulgaria, prefers steppic, arid, uncultivated habitats, but also found in alfalfa fields, less often corn cultures field-protecting vegetation belts. Previous studies provide only limited data regarding the diet of this cryptic species. one family group (one female four pups) was mon...

This paper studies dimensional visibility representations of graphs in which objects in d correspond to vertices and vertical visibilities between these objects correspond to edges We ask which classes of simple objects are universal i e powerful enough to represent all graphs In particular we show that there is no constant k for which the class of all polygons having k or fewer sides is univer...

Operator splitting techniques were originally introduced with the main objective of saving computational costs. A multi–physics problem is thus split in subproblems of different nature with a significant reduction of the algorithmic complexity and computational requirements of the numerical solvers. Nevertheless, splitting errors are introduced in the numerical approximations due to the separat...

purchased. Too often, this leads to the decision to use the chemicals ‘just in case’ even when their application may cause more harm than good. Alternatives that could be used as part of an IPM strategy include crop rotation and diversity, inter-row planting, management of planting schedules, tillage and irrigation according to the minimisation of pest dangers, and biological strategies, such a...
