This paper presents a new self-adaptive optimization removal algorithm for evolutionary structural optimization (ESO) method. The elements rejection based on this algorithm is determined by their own attributes (statistical distribution of element sensitivity) rather than comparing the sensitivities to manual selective parameters in the traditional removal process. Thus, it avoids the choices a...

the objective of the present study was to investigate the effects of a sustained-release multi-trace element ruminal bolus on sex ratio, the reproductive performance and lambs growth of afshari ewes. eighty afshari cycling ewes during breeding season were used in the trial. the animals were synchronized using cidr for 14 days and assigned into 4 groups including: group 1 (n=20) received a singl...

Robustness of reinforced concrete (RC) structures is an ongoing challenging research topic in the engineering community. During extreme event, loss vertical load-bearing elements can activate large-deformation resisting mechanisms such as membrane and catenary actions beams floor slabs cast-in-situ RC buildings to resist gravity loads. However, few studies have been conducted for precast (PC) b...

introduction: the aim of this study was to evaluate the efficacy of combined intratympanic and systemic steroid therapy compared with systemic steroid therapy alone in idiopathic sudden sensorineural hearing loss (issnhl) patients with poor prognostic factors.     materials and methods: seventy-seven patients with sudden sensorineural hearing loss (ssnhl) who had at least one poor prognostic fa...

In this article, the modeling and simulation of material removal during machining processes with a finite element method is discussed. The model links a dexel based material removal simulation with a thermomechanical finite element method to forecast thermical and process-related shape errors during machining processes. It is modeled mathematically by linking heat conduction equation with the d...

A standard matrix representation A of a matroid M represents M relative to a fixed basis B. Deleting rows and columns of A correspond to contracting elements of B and deleting elements of E(M)−B. If M is 3-connected, it is often desirable to perform such an element removal from M while maintaining 3-connectivity. This paper proves that this is always possible provided M has no 4-element fans. W...

Species extinctions pose serious threats to the functioning of ecological communities worldwide. We used two qualitative and quantitative pollination networks to simulate extinction patterns following three removal scenarios: random removal and systematic removal of the strongest and weakest interactors. We accounted for pollinator behaviour by including potential links into temporal snapshots ...
