Geographic clines in body size havebeendescribed formany species, but relatively few investigations have tested hypotheses for the ontogenetic mechanismsmaintaining geographic clines. We formalize and test the predictions for the role of ontogenetic mechanisms (e.g., hatching timing and size, juvenile developmental time, juvenile growth rate) in maintaining a longitudinal cline in adult body si...

This work reports on the use of cultural practices that influence grasshoppers’ nymphal emergence. Grasshopper eggs were buried at depths of 2, 14, 18, 22, and 26 cm in laboratory arenas. Nymph eclosion ranged from 77.5 to 87.8%. However, nymph emergence, measured as the number of nymphs that reached the soil surface, was estimated at 70.9% when eggs were buried at 2cm, but was reduced to 2.5 %...

CloudIoT is a new paradigm, which has emerged as result of the combination Cloud Computing (CC) and Internet Things (IoT). It experienced growing rapid development, it become more popular in information technology (IT) environments because advantages offers. However, due to strong use this especially smart cities, problem imbalance load emerged. Indeed, satisfy needs user, intelligent objects s...

This paper is focused on the study of basic problem vehicle for reducing cost factor and increasing efficiency solution. Features constraint uses some capabilities algorithm used to modify it dynamically between nodes depot. demonstrated with a feasible schedule every node minimizes total as much possible. The analysis based address given model solution procedure.The purpose this research provi...

Aiming at the characteristics of high computational cost, implicit expression and nonlinearity performance functions corresponding to large complex structures, this paper proposes a support-vector-machine- (SVM) based grasshopper optimization algorithm (GOA) for structural reliability analysis. With method, problem is transformed into an problem. On basis using finite element method (FEM) gener...

Grasshopper optimization algorithm (GOA) is one of the promising algorithms for problems. However, it has main drawback trapping into a local minimum, which causes slow convergence or inability to detect solution. Several modifications and combinations were suggested overcome this problem. This paper presents modified grasshopper (MGOA)-based genetic Modifications rely on certain mathematical a...

A comparison of the ability of mammals to localize sound revealed that among the animals examined to date, none of the rodents have been able to localize as accurately as the carnivores. Because all of these rodents are prey animals, the question arises as to whether their poor localization acuity is a phyletic trait of Rodentia or whether it is a trait common to prey species that may be under ...
