West Virginia is the third most heavily forested state in the U.S. and produces 2.41 million dry tons of wood residues annually. These wood wastes are sustainable and can be used as feedstock for biofuels, bio-gas and green electricity. Biomass sustainability, efficient harvesting, extraction, and transportation of woody biomass are the key to the economic success of wood residue utilization. T...
The effects of development and the uncertainty of a changing climate in eastern Africa pose myriad challenges for water managers along the Blue Nile. Sudan’s large irrigation potential, hydroelectric dams, and prime location within the basin mean that Sudan’s water management decisions will have great social, economic and political implications for the region. At the same time, Sudan’s water us...
Load modeling is widely used in power system studies. Two types of modeling, namely, static and dynamic, are employed. The current industrial practice is the static modeling. Static modelss are algebraic equations of active and reactive power changes in terms of voltage and frequency deviations. In this paper, a component based on static modeling is employed in which the aggregate model is deri...

This article proposes a novel mathematical approach to deal with cyberattacks (CAs) impacting on modernized microgrid's (MMG) tertiary control. MMGs use many entities based voltage-source converters form the fully integrated power and energy system (FIPES). Having such for necessitates engineers considering cybersecurity addressing its effects from beginning of designing building systems. Using...
following the categorical approach to universal algebra through algebraic theories, proposed by f.~w.~lawvere in his phd thesis, this paper aims at introducing a similar setting for general topology. the cornerstone of the new framework is the notion of emph{categorically-algebraic} (emph{catalg}) emph{topological theory}, whose models induce a category of topological structures. we introduce t...
Farmers in the Indus Basin, Pakistan have generally switched to groundwater for additional water supplies due to the irregular supply of irrigation water; currently over 50% of the agricultural land in the basin is at least partially irrigated by tubewells. These wells pump fresh groundwater, which essentially is the result of massive leakage from irrigation canals into the originally saltwater...
the objective of this work is to analyze the effects of decrease in water subsidies (increase in the price of the water) on various economic sectors in order to promote the conservation of this resource based on the actual price of water. but over the past decades, various subsidizing methods hold the cost of water down. on the other hand, the indiscriminate use of these resources led the gover...
Abstract The increase of energy utilization reinforced the need reducing primary consumption based on fossil fuels and limitation carbon dioxide (CO 2 ) emissions to atmosphere. Such goals aim at provision affordable generally clean for citizens. However, final decision making is hard be achieved, due not only multitude variety such proposed technologies, but also consideration different criter...
