Efficient task partitioning plays a crucial role in achieving high performance at multiprocessor platforms. This paper addresses the problem of energy-aware static partitioning of periodic realtime tasks on heterogeneous multiprocessor platforms. A Particle Swarm Optimization variant based on Min-min technique for task partitioning is proposed. The proposed approach aims to minimize the overall...

the invertebrate communities of the northern chilean rivers are characterised by their marked endemism andspecificity of their community structure in different basins. the river systems located in the atacama desert are endorheicand are affected by the rainy period of january-february commonly known as the “bolivian winter“. the present study isthe first report on the observations of arthropods...
abstract during growing seasons of years 2006 & 2007, a faunistic survey on syrphidae family(diptera) in agroecosystems of neyshabor region, khorasan-e-razavi province was carried out. in this study, 3 collection methods: yellow water trap, malaise trap and sweeping net were applied. the results showed a large difference between different collection methods. specimens of 14 species collected by...
The true bugs (Insecta: Heteroptera) are one of the most important insects which included several pest and beneficial species (predators and parasitoids) and therefore have important role in agroecosystems. The fauna of aquatic and semi-aquatic Heteroptera was studied in paddy fields and around aquatic ecosystems in some regions of Iran through 2004-2009. Totally 58 species from 14 families inc...
Dictyoptera or cockroaches are one of the important orders of insects that their feeding habits and presence in man habitual cause serious difficulties to him. There are many control methods that chemical method is the most usual of them. In order to determine cockroaches species in Hamadan during 1370-71 we studied more than 900 speciemens and six species were indentified. Suseptibilit...
Infestation of grain by insects is widely controlled by the use of insecticides. Use of contact insecticides results in chemical residues left in the food which may have adverse effects on humans. Also insects develop resistance to both contact insecticides and fumigants. Microwave disinfestation offers an alternate way to disinfest grain. Microwaves are electromagnetic waves with frequencies r...
