In the current study, the qualitative status of potable well water was assessed using the groundwater quality index during a course of 4 years (2014-2017). This study was carried out with an aim to monitor the drinking water resources from 12 potable wells on the multivariate analysis basis and for determination of groundwater quality index, the following 13 physicochemical parameters including...
The comprehensive energy system in the park is effective ways of solving problems low efficiency social utilization and difficulty absorbing renewable clean energy. Due to inherent characteristics thermal load, it will be utilized as adjustable load take part system’s ideal arrange. Therefore, a coordinated optimization source storage model, park’s system, which takes into account flexible resp...
Three equivalence relations are considered on the set of n x n matrices with elements in Fo' an · abelian group with absorbing zero adjoined. They are the relations of diagonal similarity, diagonal equivalence, and restricted diagonal equivalence. These relations are usually considered for matrices with elements in a field, but only multiplication is involved. Thus our formulation in terms of a...
Microwave-absorbing materials are widely utilized in military and civilian applications. Moreover, their environmental potential to refine electromagnetic pollution has promoted importance. An ideal conjugated organic polymer for use as a microwave-absorbing material should possess high porosity, low density, long backbone, narrow energy band gap, proper conductive relaxation loss, vast specifi...
The problem of terminating a transmission line that consists of a set of coupled loop resonators to support the propagation of magneto-inductive waves is considered. Since the ideal terminating impedance is not easily realisable end-reflections are generally obtained from such a line. Techniques are developed to calculate the reflection coefficient from a line terminated with a finite number of...
The Casimir force is one of the most accessible experimental consequences of vacuum fluctuations in the macroscopic world. It is the most significant force between neutral, non-magnetic objects at distances on the micrometer scale and below. For many experiments searching for novel short-range forces predicted by unification models, theoretical calculations of the Casimir force are crucial and ...
The possibility of using the self-induced transparency effect to passively modelock lasers has been discussed since the late 1960s, but has never been observed. It is proposed that quantum cascade lasers are the ideal tool to create this modelocking, due to their rapid recovery times and relatively long coherence times and because it is possible to interleave gain and absorbing layers. Converse...
Ideal photovoltaic cells would be black, absorbing all of the Sun’s radiation, whereas Nature’s machinery for solar energy harvesting— photosynthesis—looks green. Organic semiconductor devices, based on molecular building blocks, lie conceptionally between the extremes of inorganic and photosynthetic light harvesting. How can organic solar cells appear almost black if they are based on molecula...
