The reciprocal crosses were performed using Benihoppe, as the female parent, four disease-resistant European cultivars Albion, Camino Real, Ven- tana and Virginia, and one Japanese cultivar Meiho as the male parent. Then, the seedling propagation coefficient, disease resistance, fruit quality and yield of F1 gen- eration of the combinations were detected and compared. Besides, the breeding and traits of a new cultivar F1-40 developed from the cross between Benihoppe and Mei- ho were introduced as an instance to prove the feasibility of the combinations/lines.展开更多

In order to handle the complexity, in the framework of stochastic local search optimization, learning and optimization has been deeply interconnected through interaction with the decision maker via the visualization approach of the online graphs. Consequently a number of complex optimization problems, in particular multiobjective optimization problems, arising in widely different contexts have been effectively treated within the general framework of RSO. In solving real-life multiobjective optimization problems often most emphasis are spent on finding the complete Pareto-optimal set and less on decision-making. However the com-plete task of multiobjective optimization is considered as a combined task of optimization and decision-making. In this paper, we suggest an interactive procedure which will involve the decision-maker in the optimization process helping to choose a single solution at the end. Our proposed method works on the basis of Reactive Search Optimization (RSO) algorithms and available software architecture packages. The procedure is further compared with the excising novel method of Interactive Multiobjective Optimization and Decision-Making, using Evolutionary method (I-MODE). In order to evaluate the effectiveness of both methods the well-known study case of welded beam design problem is reconsidered.展开更多

Because the construction plan is different, the construction period will be different and the machines and tools required will be different, thus the expenses incurred will also be different. Therefore, the on-site technical engineer should put forward a technically advanced, technically reasonable and organizationally capable construction plan based on the contract period, taking into account factors such as the scale, nature, complexity, site conditions, equipment conditions and personnel quality of the project, and strive to reduce the project cost. In this paper, from the aspects of the determination of construction methods, the selection of construction machines and tools, the arrangement of construction sequence and the organization and arrangement of construction, the application of the optimization method of construction scheme in the cost management of engineering projects, such as the formulation of advanced, economical and reasonable construction scheme, the rational selection of machinery and the full play of the efficiency of machinery, is analyzed, and the importance of construction scheme in the cost management of projects is expounded.展开更多

This is why designers must ensure the safety, functionality, aesthetics and cost-effectiveness of the building when designing the building, and also consider the convenience of the building. Therefore, architectural design units must optimize the design. Only in this way can the various functions of architecture be unified and promote the stable development of China's construction industry. On this basis, the application of design optimization method in architectural structure design is analyzed and discussed. The rapid development of social economy has also improved people's quality of life. In this context, there are more stringent requirements for life and environment. In the process of architectural design, designers must actively use the construction method of architectural optimization, so that the comfort of the house can not only be improved, but also fully meet people's living needs. In addition, using the construction method to optimize the building can also significantly reduce the construction cost without affecting the house performance and quality, which can also greatly improve the economic benefits of engineering companies and promote the better development of China's construction industry.展开更多

We show that an optimal solution at PHY-MAC level can be highly suboptimal at application level, and then show that making the cross-layer framework application-aware through a prioritized dropping policy capitalizing on the inherent scalability of Motion JPEG2000 video streams leads to drastic average video quality improvements and inter-user quality variation reductions of as much as 10 dB PSNR, without affecting the overall energy consumption requirements.展开更多

文摘This paper introduces a video application-aware cross-layer framework for joint performance-energy optimization,considering the scenario of multiple users upstreaming real-time Motion JPEG2000 video streams to the access point of a WiFi wireless local area network and extends the PHY-MAC run-time cross-layer scheduling strategy that we introduced in (Mangharam et al., 2005; Pollin et al., 2005) to also consider congested network situations where video packets have to be dropped. We show that an optimal solution at PHY-MAC level can be highly suboptimal at application level, and then show that making the cross-layer framework application-aware through a prioritized dropping policy capitalizing on the inherent scalability of Motion JPEG2000 video streams leads to drastic average video quality improvements and inter-user quality variation reductions of as much as 10 dB PSNR, without affecting the overall energy consumption requirements.
