Organizations expose to financial risk that can lead to bankruptcy and loss of business is increased nowadays. This may leads to discontinuity in operations, increased legal fees, administrative costs and other indirect costs. Accordingly, the purpose of this study was to predict the financial crisis of Tehran Stock Exchange using neural network and genetic algorithm. This research is descripti...
Because of rapidly rising network traffic, ISP providers are trying to create new network structures and extend more resources to control the growth of demands. It is important to efficiently split the network bandwidth among different sources so that each user has enough bandwidth. Traffic engineering is used to achieve this goal. Performing reliable and efficient network ope...
the aim followed in this study was to compare the performance of multiple regression vs neural network models to predict the activity of antioxidant enzymes super oxide dismutase (sod), cat alase (cat), ascorbate pero xidase (apx) and peroxidase (pox) in the shoots of wheat (triticum aestivum), alvand cultivar in a soil polluted with cadmium. the treatments consisted of four levels of cadmium (...
رویکرد این پژوهش ترکیبی از مراحل مختلف فرایند انتقال تکنولوژی است، که با تمرکز بیشتر در مراحل انتخاب روش انتقال و بومی سازی و جذب یک تکنولوژی، یک مسیر مناسب را با هدف ارتقا سطح فنی جهت جذب تکنولوژی وارداتی پیشنهاد می دهد. با توجه به نوع مساله پیش رو در این پژوهش که نوعی تصمیم گیری چند معیاره می باشد، برای تجزیه و تحلیل نتایج حاصل از مصاحبه با متخصصین و پرسشنامه های تکمیل شده و به دلیل ارتباط تع...
Introduction: C. elegans neural network is a good sample for neural networks studies, because its structural details are completely determined. In this study, the virtual neural network of this worm that was proposed by Suzuki et al. for control of movement was reconstructed by adding newly discovered synapses for each of these network neurons. These synapses are newly discovered in the actu...
We study the capacity of point-to-point erasure networks under a restricted form of network coding to which we refer as spatial network coding. In this form of coding, the nodes can not perform coding on successive packets which are received from one incoming link. The coding at a node is restricted to the packets received at the same time slot from different incoming links...
Networking can help invoke research potentials existing in organizations, while it resolves the current related problems. Considering the significance of this issue and the improper network pattern of business organizations, a need to design a coordinative communication network for the researches performed in the country’s executive agencies was strongly felt. Thus, this study investigated...
Today, information networks play an important role in supply chain management. Therefore, in this article, clustering-based routing protocols, which are one of the most important ways to reduce energy consumption in wireless sensor networks, are used to optimize the supply chain informational cloud network. Accordingly, first, a clustering protocol is presented using self-organizing map neu...
In this study, a new configuration of heat pipes as Heat Pipe Network is introduced. Here, the heat pipe network is designed, constructed and then has been under the performance assessment. This heat pipe network consists of 4 vertical heat pipes connected to evaporator collector from bottom and condenser collector from top. In order to investigate the effect of nanofluids on the thermal effici...
Logistics Network Design includes network configuration decisions having long-standing influences on other tactical and operational decisions. Recently, regarding environmental issues and customer awareness and global warming closed-loop supply chain network design is taken into consideration. The proposed network for the integrated forward and reverse logistics is developed by formulating a cy...
