a numerical model for two-phase debris flows is developed in this paper, on the basis of understanding of the physical characteristics of debris flows from field investigations and experiments. employing a moving coordinate, the kinetic energy equation of gravel particles in unit volume in debris flow is developed by considering the potential energy of the particles, energy from the liquid phas...

e nergy consumption has increased significantly in iran during the recent decades. in this study, an inter-industrial model has been improved to investigate the sources of the changes in the energy consumption of the country. the input-output tables of iran for the years 1988 and 2001 have been employed as the database of the model. the innovation of this research allows the researchers to stud...

black tea sample was dried by a vibro-fluidized bed dryer to find its aerodynamic behavior and thermal performance during drying. the drying experiments were conducted at three different inlet air temperatures of 100, 115 and 130°c and fluidization condition at five vibration intensity levels of 0 (no vibration), 0.063, 0.189, 0.395 and 1.184. the results showed that bed channeling and defluidi...

in this paper, an algorithm , based on genetics and auxiliary nodes, to reduce energy consumption in wireless sensor networks has been presented. in this research, by considering some parameters as energy and distance, a target function has been created, which is more optimum comparing to other methods. in this research cluster head is selected by genetic algorithm. in rawsn algorithm a new tec...

energy consumption in the residential sector is a complex socio-technical problem that can be explained using acombination of physical, demographic and behavioural characteristics of a house and its occupants. in this paper, byusing the energy consumption data for the residential sector of shiraz in iran, the effect of built area (ba) andoccupant number (occ) on annual energy consumption (ec) w...

the benefits of using mineral admixtures as a partial replacement of portland cement (pc) are well established in the literature. economic and environmental advantages by reducing co2 emissions are well known. this paper examines the influence of intergrinding and separate grinding on the amount of energy consumption, blaine fineness and particle size distribution (psd) of blended cements, name...

energy as an important production factor has significant effects on economic growth. identifying the relationship between energy and economic growth can help to improve governmental energy policies. applying ardl and ecm methods, this paper examines the longrun and shortrun causality relationships between (1) energy consumption and economic growth and (2) energy consumption and employment in va...

abstractthe reform of energy subsidies has affected economic growth, as a result of household and firms’ behavior. however, despite the energy consumption and economic growth decrease in the short run, it is expected that economic growth will increase as a result of an adjustment in economic agents’ behavior over the mid- and long-terms. as is appropriate with these changes, energy consumption ...

In recent years, the issue of energy consumption modeling techniques in the building sector has been widely considered by researchers and managers. Researches indicate that energy consumption in residential sector is one of the main parts of the total consumption. Moreover, the urban residence is supposed as a significant consumer of energy in every country and therefore a focus for energy cons...
