We extend EUCLID, a computational strategy for automated material model discovery and identification, to linear viscoelasticity. For this case, we perform priori selection by adopting generalized Maxwell expressed Prony series, deploy EUCLID identification. The methodology is based on four ingredients: i. full-field displacement net force data; ii. very wide library — in our large number of ter...

‎in this paper, using the idea of convexificators, we study boundedness and nonemptiness of lagrange multipliers satisfying the first order necessary conditions. we consider a class of nons- mooth fractional programming problems with equality, inequality constraints and an arbitrary set constraint. within this context, define generalized mangasarian-fromovitz constraint qualification and show t...

Spectrum is a valuable, scarce and finite natural resource that is needed for many different applications, so efficient use of the scarce radio spectrum is important for accommodating the rapid growth of wireless communications. Spectrum auctions are one of the best-known market-based solutions to improve the efficiency of spectrum use. However, Spectrum auctions are fundamentally differen...

In this paper, a vehicle-to-vehicle (V2V) trajectory planning algorithm for two vehicles driving in an arc-shaped road is represented, which the characteristics of human drivers are taken into consideration. Safety constraints including vehicle stability, boundaries, and collision avoidance considered. The boundary constraint realized with potential field method. method also employed to realize...

A new bandwidth allocationmodel is studied in this paper. In this model, a system, such as a communication network, is composed of a finite number of users, and they compete for limited bandwidth resources. Each user adopts the decision that maximizes his or her own benefit characterized by the utility function. The decision space of each user is subject to constraints. In addition, some users ...

escherichia coli (e. coli) is a normal inhabitant of the gastrointestinal tract of vertebrates, including humans. phylogenetic analysis has shown that e. coli is composed of four main phylogenetic groups (a, b1, b2 and d). group a and b1 are generally associated with commensals, whereas group b2 is associated with extra-intestinal pathotypes. most enteropathogenic isolates, however, are assigne...

background: the emergence and propagation of different phylogenetic groups of antimicrobial-resistant e. coli have become a worldwide health concern in human and veterinary medicine. therefore, the evaluation of the phylogenetic distribution of antibiotic-resistant e. coli is important for therapeutic and economic purposes. the aims of this study were to determine phylogenetic groups and patter...

phylogenetic analysis has shown that escherichia coli is composed of four main phylogenetic groups (a, b1, b2 and d). characterization of phylogenetic groups is of clinical interest, as group a and b1 generally associated with commensals, whereas most enteropathogenic isolates are assigned to group d, and group b2 is associated with extra-intestinal pathotype. one hundred e. coli strains recove...

In this research, an integrated approach is presented to simultaneously solve quay crane scheduling and yard truck scheduling problems. A mathematical model was proposed considering the main real-world assumptions such as quay crane non-crossing, precedence constraints and variable berthing times for vessels with the aim of minimizing vessels completion time. Based on the numerical results, thi...
