The estimation of the population total $t_y,$ by using one or more auxiliary variables, and the population ratio $ heta_{xy}=t_y/t_x,$ $t_x$ is the population total for the auxiliary variable $X$, for a finite population are heavily discussed in the literature.In this paper, the idea of estimation the finite population ratio $ heta_{xy}$ is extende
After almost 30 years and many projects investigated all over the world, the full potential that 3D printing technology can bring to the construction industry has yet to be realised.There are many challenges that face the application of 3D printing technology to the construction field.Among these challenges, mixture proportion design is crucial for
Abstract Background Epidemiological and genetic studies suggest that elevated triglyceride (TG)-rich lipoprotein levels in the circulation increase the risk of cardiovascular disease.Prescription formulations of omega-3 fatty acids (OM3FAs), mainly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), reduce plasma TG levels and are approved
Decomposition of organic matter is an important ecosystem process governed in part by bacteria.The process of decomposition is expected to benefit from interspecific bacterial interactions such as resource partitioning and facilitation.However, the relative importance of resource niche breadth (metabolic diversity) and resource niche overlap (funct
This Glitter Globe research work considers a scenario of cloud computing job-shop scheduling problems.We consider m realtime jobs with various lengths and n machines with different computational speeds and costs.Each job has a deadline to be met, and the profit of processing a packet of a job differs from other jobs.Moreover, considered deadlines a
