a design discharge is an important issue in the design process of pressurized irrigation networks. underestimating the desing discharge affect, the required pressure and offtake discharge, increase the cost of the network. because of the lack of a standard and reliable method for this propuse, usually different approches are used by designers. the network fails to provide the required flow rate...

Background: A prerequisite for successful embryo implantation is adequate preparation of receptive endometrium and the establishment and maintenance of a viable embryo. The success of implantation further relies upon a two-way dialogue between the embryo and uterus. However, molecular bases of these preimplantation and implantation processes in humans are not well known. Materials and Methods: ...

Most of the infrastructures planning problems like facility location, allocation of resources, and path planning are based on the network topology created from maps with spatial and non-spatial attributes. The problem is where do you locate new facilities? In this example, the facility can be on any node i.e. at any road junction. It is also possible to locate a facility in the middle of the ro...

In today’s competitive environment, business process reengineering has a great role in improving operational efficiency for most organizations. This paper bases on social network analysis (SNA) as a new approach to work over configurable efficiency for business process reengineering without respect to other factors. Organization is regard as the network where units or actor are as nodes and rel...

Data Farming, network applications and approaches to integrate network analysis and processes to the data farming paradigm are presented as approaches to address complex system questions. Data Farming is a quantified approach that examines questions in large possibility spaces using modeling and simulation. It evaluates whole landscapes of outcomes to draw insights from outcome distributions an...

Being aimed at the influence of ship-size and cargo-demand changes on container shipping networks, to reveal the evolution process of container shipping networks structure form, this paper respectively designed the operation models for two major container shipping networks structure forms: Multi-port-calling network and Hub-and-spoke network, to maximizing the investment efficiency. Based on th...

Current traditional technologies, while enabling effective knowledge sharing and accumulation, seem to be less supportive of knowledge organization, use and consensus formation, as well as of collaborative decision making process. To address these limitations and thus to better foster collective decisionmaking around complex and controversial problems, a new family of tools is emerging able to ...

Purpose – The purpose of this paper is to provide a framework and prototype software to use IDEF3 descriptions as a knowledge base from which a queuing network (QN) analysis is performed to compute system performance measures as part of quick response manufacturing. This intends to help domain experts obtain informative quantitative performance measures such as resource utilization, waiting tim...

in developing countries, the domination of peripheral and dependent capitalism relations and the lack of appropriate structures and channels of attracting, this system have caused some kind of spatial-anatomic unbalances that has resulted in the appearance of single cities with national and regional prevalence. this situation is the main reason for small, medium and intermediate cities to lose ...
