In this article, new multiple-production systems based on the micro-combined cooling, heating and power (CCHP) cycle with biomass heat sources are presented. proposed system, absorption refrigeration subsystems a water softener system have been used to increase efficiency of basic reduce waste. Comprehensive thermodynamic modeling was carried out system. The validation optimization via genetic ...

in this paper, we propose a new approach for ranking all fuzzynumbers based on revising the ranking method proposed by ezzati et al. cite{ezzati}.to this end, we present and investigate some properties of the proposed approach indetails. finally, to illustrate the advantage of the proposed method, it is applied to several groups of fuzzy numbers and the results are compared with other related a...

In this paper we introduce the D-resultant of two rational functions f(t), g(t) ∈ K(t) and show how it can be used to decide if K(f(t), g(t)) = K(t) or if K[t] ⊂ K[f(t), g(t)] and to find the singularities of the parametric algebraic curve define by X = f(t), Y = g(t). In the course of our work we extend a result about implicitization of polynomial parametric curves to the rational case, which ...

In this research, a new technetium-99m generator has been developed with addition of Cerium oxide to alumina column.  The adsorption behaviors of 99Mo in the form of molybdate and 99mTc in the form of pertechnetate on CeO2/Al2O3 was investigated and showed that the adsorption capacity of molybdate on this generator is higher than usual generator using Al2O3. Ceric ions were selected as an addit...

This paper presents a parametric study and comparison of turbocompound gasoline engine with diesel based on analysis done in previous papers. Turbocompounding is an important technique to recover waste heat from exhaust reduce CO_2 emission, improving fuel economy. By the time detected one biggest problems for IC engines pollution. Downsizing studies are popular at industry moments get emission...

This paper presents an approach to calculate the equivalent stray capacitance (SC) of n-turn of the helical flux compression generator (HFCG) coil with multi layer conductor wire filaments (MLCWF) in the form of rectangular cross-section. This approach is based on vespiary regular hexagonal (VRH) model. In this method, wire filaments of the generator coil are separated into many very small simi...

We consider Landau’s type inequalities of the form ‖Aku‖n ≤ Cn,k‖u‖n−k‖Anu‖k, u ∈ D(A), 0 < k < n, where A is the infinitesimal generator of either a strongly continuous semigroup or a strongly continuous cosine function of linear contractions on a Banach space X. The constants Cn,k are computed for n ≤ 6.

In his celebrated paper on the algebraic structure of ConvoJutional codes, Forney 111 showed that by using the invariant-factor theorem, one can transform an arbitrary polynomial generator matrix for an (n, k ) convolutional code C into a basic (and ultimately a minimal) generator matrix for C. He also showed how to find a polynomial inverse for a basic generator matrix for C, and a basic gener...
