We show that the method of counting closed walks in strongly regular graphs rules out no parameter sets other than those ruled out by the method of counting eigenvalue multiplicities. Following Bose [2], a strongly regular graph with parameters n, k, λ, μ means an undirected graph G such that • G has n vertices, • G is regular of degree k, • every two adjacent vertices of G have precisely λ com...

A thirty Rahmani weaned male lambs of average body weight (27.28±1.40 kg) were randomly allotted to three similar groups, ten lambs in each, to study the benefit of commercial feed additives Tonilisat (Saccharomyces cerevisiae) and Roemin W2 (Lactobacillus acidophilus, Lactobacillus thermophilus, Bifidobacterium and Lactose) as growth promoters on lambs performance, digestibility, rumen activit...

The present study evaluated the impact of hydrological variability on hydrodynamics an urban lake in Brazil, considering water quality dynamics and its effects evaporation. Storm Water Management Model (SWMM) was applied to basin, two-dimensional model CE-QUAL-W2 used simulate two models were coupled carry out integrated basin-lake modeling. Then, applied: a transient complete mixing empirical ...

Résumé. En Analyse Statistique Implicative, le logiciel CHIC offre des interfaces efficaces pour un usage accessible au non-spécialiste. Ce dernier est confronté à la lecture et l’interprétation des représentations graphiques produites par ce logiciel. Or contrairement à une idée répandue : « un dessin, un graphique parle de lui-même », l’interprétation des graphiques requiert des connaissances...

We explored the B-C-O system at pressures in the range 0-50 GPa by ab initio variable-composition evolutionary simulations in the hope of discovering new stable superhard materials. A new tetragonal thermodynamically stable phase B4CO4, space group I4[combining macron], and two low-enthalpy metastable compounds (B6C2O5, B2CO2) have been discovered. Computed phonons and elastic constants show th...

Coastal wastewater and storm water systems can be overwhelmed during high precipitation events, particularly when compounded by surge that blocks spillways drainage ways. Sea level rise (SLR) brings increased risk of such compound flooding triggering sanitary sewer overflows (SSO) which release waste into the local environment. A logistic regression model was developed to better predict this in...

Abstract The rivers rejuvenate themselves by traveling over a distance, thereby they assimilate the pollution load and cause their own self-cleansing, also termed ‘Self-purification capacity’. To ascertain such assimilative capacity of river system, various water quality models (WQMs) were studied. Out numerous WQMs, six including QUAL2Kw, WASP, SWAT, SIMCAT, MIKE-11, CE-QUAL-W2 selected studie...

and Applied Analysis 3 2. Several Reproducing Kernel Spaces In this section, several reproducing kernels needed are constructed in order to solve 1.1 and 1.2 using RKHSmethod. Before the construction, we utilize the reproducing kernel concept. Throughout this paper C is the set of complex numbers, L2 a, b {u | ∫b a u2 x dx < ∞}, l2 {A | ∑∞i 1 Ai 2 < ∞}, and the superscript n in u n t denotes th...

Let Fq be a finite field of characteristic p and let W2(Fq) the ring Witt vectors length two over Fq. We prove that for any integer n such divides n, groups SLn(Fq[t]/t2) SLn(W2(Fq)) have same number irreducible representations dimension d, each d.
