This study aimed to evaluate the efficiency of energy consumption and economic analysis of different watermelon cultivation systems in Fars Province of Iran. Watermelon production systems were classified into five systems, namely, custom tillage (group 1), conservation tillage (group 2), traditional planting (group3), semi mechanized planting (group 4), and mechanized planting (group 5). Data w...

Nowadays, there are lots of problems in Cloud data center such as high energy consumption and low efficiency. We model a cloud environment with physical hosts and virtual machines, and design an Energy-Aware Virtual Machine Scheduling strategy (EAVMS) to reduce energy consumption and improve utilization rate by integrating system resource such as computing, storage and bandwidth resources. Expe...

Due to low energy price, economic optimization of consumption has no justification for users in Iran. Nowadays, the issue of ending fossil fuels, production of greenhouse gases and the main role of building in consumption of considerable amount of energy has drawn the focus of global researches to a new concept called net zero energy building. In this study, modeling, simulation and energy anal...

in purpose of this paper is to discuss the occurance of bifurcation and chaos in nonlinear systems in general, and the pearl-reed model whi.ch has been used for representing the lynamical behavior of the petroleum resources in particular. based on this investigation, it is shown that the observed tluctuations in the petroleum market can be erplained by its interral dynamics and the increase in ...

Energy efficiency is gaining more and more importance, since well-known ecological reasons lead to rising energy costs. In consequence, energy consumption is now also an important economical criterion. Energy consumption of single hardware resources has been thoroughly optimized for years. Now software becomes the major target of energy optimization. In this paper we introduce an approach calle...

The evolution of network technologies and their reliability on the one hand, and the spread of virtualization techniques on the other hand, have motivated the use of execution and storage resources allocated by distant providers. These resources may progress on demand. Cloud computing deals with such aspects. However, these resources are greedy in energy because they consume huge amounts of ele...

In manufacturing, thermal spray technology encompasses a group of coating processes that provide functional surfaces to improve the performance of the components and protect them from corrosion, wear, heat and other failings. Many types and forms of feedstock can be thermal sprayed, and each requires different process conditions and life cycle preparations. The required thermal energy is genera...

open local energy requirements, the need for regional energy planning in the process of macro-planning can make significant energy. in this respect, the outer part of the direct effects of energy production and consumption locally effective, less energy planning processes will be huge. in this paper, the issue of continuity of energy supply, long-term access to resources and lower emissions fro...

In Cloud computing most of the energy efficient techniques give more attention to energy consumption in task resources such as CPU and memory of the physical machines in cloud. The network bandwidth is used to connect users to the cloud were paid less attention, the cloud network transmission and switching components also consumes significant percentage of total energy consumption. In the propo...
