in this paper, non parametric data envelopment analysis (dea) was subjected to the energy data of wheat producers in punjab state, india, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. the main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...
Recent advances in computing and communication technologies enable the popularity of versatile mobile devices, which account for a substantial amount of energy use. The energy consumption has become of unprecedented importance not only from an economic perspective but also for the environment protection, particularly in a cloud computing systems which provide ubiquitous services. Conventional d...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
Boilers are one of the major energy consumers in the building. For this reason, increasing the efficiency of this device and improving its performance is an effective step in solving the problems in building energy and reducing waste energy. Due to the limited resources of fossil fuels and the increasing cost of energy in the world, manufacturers of these equipment are always working to improve...
Background: Moral hazard is referred to behavior change of service-provider (physician) and service-consumer (patient) as the result of insurance. It is a serious concern for health insurance and insurance policies market in the health system reforms. Moral hazard usually leads to such unpleasant consequences as welfare loss, increasing health expenditures, decrease of insurance coverage, unn...
Introduction: The hospital is known as the biggest and the most costly performing unit of health care systems therefore, paying attention to efficiency of cost is very important. Survey the technical efficiency in hospitals is the objective of this paper. Methods: This study estimate technical efficiency in hospitals of Iran University of Medical Sciences by Data Envelopment Analysis, in 2000 t...
To compare the general equilibrium effects of common environmental policies, I develop a model of directed technical change with endogenous exploration for depletable fossil resources, endogenous innovation in technologies for accessing renewable resources, and endogenous innovation in technologies for converting fossil and renewable resources into energy services. I find that a supply restrict...
Nowadays laser is extensively used in various industrial, communicative, medical, and other fields. Using laser in medicine has enabled physicians to perform the most accurate and finest operations within few minutes. Non-observance of safety points during laser performance could be seriously harmful for the medical staff and the patient. Therefore, in order to prevent the possible damage of th...
cloud computing refers to services that run in a distributed network and are accessible through common internet protocols. it merges a lot of physical resources and offers them to users as services according to service level agreement. therefore, resource management alongside with task scheduling has direct influence on cloud networks’ performance and efficiency. presenting a proper scheduling ...
