Abstract Buckling is a critical phenomenon in structural members under compression, which could cause catastrophic failure of structure. To increase the buckling resistance design, novel topology optimization approach based on bi-directional evolutionary (BESO) method proposed this study with consideration constraints. The BESO benefits from using only two discrete statuses (solid and void) for...

• Section 2 defines the basic notation; • Section 4.2.1 states Conditions 1–3; • Section 4.2.2 defines the vectors Qa and Qb and the prediction errors ai and bi , and introduces the σx and σx,y notation for population variances and covariances; • Section 5 defines the vector Q and the prediction errors a∗∗ i and b∗∗ i . Let p̃A = nA/n [as in remark (iii) after Corollary 1.2]. Extend Section 2’s ...

Code-Smells represent design situations that can affect the maintenance and evolution of software. They make a system difficult to evolve. Code-smells are detected, in general, using quality metrics that represent some symptoms. However, the selection of suitable quality metrics is challenging due to the absence of consensus to identify some code-smells based on a set of symptoms and also the h...

background: changes in body composition may be used for monitoring progression/ regression of a disease. prompt γ-rays in vivo neutron activation analysis (ivnaa) has been widely used for the measurement of body composition in recent years. objective: in this paper, we tried to improve the safety of ivnaa operator. methods: the most important factor for reducing the operator receiving dose is t...

A bi-level model for traffic signal optimization is developed. The predictive framework applied control in an urban network. potential of the formalization used to increase space influences with simultaneous evaluation green light and cycle durations. Thus, increased allows more parameters be considered, such as vehicles queues flows. particular modification synchronization lights approach real...

Posterior distributions for community structure in sparse planted bi-section models are shown to achieve exact (resp. almost-exact) recovery, with sharp bounds the sparsity regimes where edge probabilities decrease as O(log(n)/n) O(1/n)). Assuming posterior one may interpret credible sets enlarged sets) asymptotically consistent confidence sets; diameters of those controlled by rate concentrati...

Graph theory based methods are powerful means for representing structural systems so that their geometry and topology can be understood clearly. The combination of graph theory based methods and some metaheuristics can offer effective solutions for complex engineering optimization problems. This paper presents a Charged System Search (CSS) algorithm for the free shape optimizations of thin-wall...

It takes two design goals as different game players and design variables are divided into strategy spaces owned by corresponding game player by calculating the impact factor and fuzzy clustering. By the analysis of behavior characteristics of two kinds of intelligent pigs, the big pig’s behavior is cooperative and collective, but the small pig’s behavior is noncooperative, which are endowed wit...
