To reduce the stress concentration and ensure structural safety for lattice structure designs, in this paper, a new optimization framework is developed optimal design of graded structures, innovatively integrating fillet designs as well yield buckling constraints. Both relative strut radii parameters are defined variables, BCC PC lattices. Numerical homogenization employed to characterize effec...

With the dramatic increase in mask costs, multi-project wafers have became an attractive choice for low-volume chip fabrication. By using the same set of masks to fabricate a number of different chips, the mask-set cost is amortized among different chip providers, leading to significant cost reduction especially for chip prototyping. In this paper we present a new algorithm for reticle floorpla...

46 (eds M.C.S. Wopereis et al.) wateror nutrient-limited production levels in a given rice environment. Yield-reducing factors induce yield losses by reducing or hampering growth, including abiotic and biotic factors. Biotic factors include weeds, pests and diseases; abiotic factors include salinity, alkalinity and iron toxicity. Attainable yield (Ya) refers to the yield that can be achieved wi...

Yield is subject to strong genotype-by-environment (G × E) interactions in the field, especially under abiotic constraints such as soil water deficit (drought [D]) and high temperature (heat [H]). Since environmental conditions show strong fluctuations during the whole crop cycle, geneticists usually do not consider environmental measures as quantitative variables but rather as factors in multi...

mulberry (morus spp.) is a perennial tree cultivated for its foliage to rear the domesticated silkworm, bombyx mori l. mulberry has improved through conventional breeding in general aims to improve the quantity and quality of leaf yield, which have direct bearing on silk productivity. leaf senescence is one of the major constraints, which restricts the quantity of quality leaf availability for ...

terminal heat and drought are the main constraints for wheat production in the vast and diverse semi-tropical rainfed regions of iran. high temperature stress during wheat’s reproductive stage is particularly detrimental, reducing both individual kernel weight and kernel number. identification of adapted genotypes can improve grain yield and its stability under heat stress conditions. selection...
