globally excessive consumption of hydrocarbon fuel in transport sector is a serious threat to the civilization due to paucity of fuel in future. also this growing use of vehicles for transport is contributing about 70% of total air pollution and causing environmental and ecological imbalances. thus the worldwide fast depletion of conventional energy resources and impact of emissions on environm...

energy and mass transfer investigations in thermal processing of fruits serve as a breakthrough in the design and scale up of drying systems. diffusivity characteristics and specific energy consumption for drying of fig fruit in a laboratory scale microwave dryer were assessed. several intervals for microwave power intensity including 0.5, 1, 1.5, 2, and 2.5 w g-1, and 6 levels of power on-off ...

jujube (zizyphus jujube mill), a valuable medicinal plant, is consumed either as fresh fruit or dried product in iran. drying jujube guarantees a longer shelf time while preserving its quality to be used in medical and pharmaceutical industries. in this research paper, the influence of several drying conditions on the effective moisture diffusivity, activation energy, energy consumption and req...

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...

the rice conversion process is an agricultural transformative industry that consumes a great deal of fossil fuel and electricity. in this study, the effect of different factors on energy consumption, energy consumption index and whitening index were investigated. the experimental design was a split plot design with four whitening periods (15, 30, 45, 60s) (main plot), three rice varieties (khaz...

the biggest challenges faced in big cities are greenhouse gas emission and growing energy needs. efficient utilization of existing infrastructures has a prominent role in response to the challenges. energy hub approach embraces performance of different energy networks. energy hub is defined as a super node in electrical system receiving distinctive energy carriers such as gas and electricity in...

concerns related to climate change and security of energy supply is pushing various countries to make strategic energy planning decisions. in this regard, energy system modelling is an appropriate method to find out the utilization of current declining non-renewable energy resources and other possible scenarios. consequently, it is available to consider various aspects of energy system decision...

let $d$ be a digraph with skew-adjacency matrix $s(d)$‎. ‎the skew‎ ‎energy of $d$ is defined as the sum of the norms of all‎ ‎eigenvalues of $s(d)$‎. ‎two digraphs are said to be skew‎ ‎equienergetic if their skew energies are equal‎. ‎we establish an‎ ‎expression for the characteristic polynomial of the skew‎ ‎adjacency matrix of the join of two digraphs‎, ‎and for the‎ ‎respective skew energ...
