In this paper, some recursive equations of reliability for linear consecutivek -out-ofn : F systems with spares d are introduced. The system of consecutive failures with sparse d is a generalized extension of consecutive-k systems, which was proposed by Zhao et al. (2007) in which the reliability formulas of these systems were presented by using finite Markov Chain imbedding approach. To facili...

This paper presents certain important aspects of the fuzzy logic extension, one of which is OFN. It includes basic definitions of that discipline. It also compares fuzzy logic arithmetic with the arithmetic of ordered fuzzy numbers in L-R notation. Computational experiments were based on fuzzy observation of the impounding basin. The results of the study show that there is a connection between ...

Biobutanol can be produced by Clostridia via an acetone–butanol–ethanol (ABE) fermentation under strictly anaerobic conditions. Oxygen-free nitrogen (OFN) gas is typically used to create conditions for ABE fermentations. However, this method not appropriate large-scale fermentations as it quite costly. The aim of work was study the feasibility butanol production from sweet sorghum juice (SSJ) C...

Bacterial mycetoma is a neglected disease mainly observed in tropical area countries and typically associated with rural conditions, making its presence in developed countries of temperate climate areas rare. However, we report the first case of an autochthonous mycetoma case in continental France that originated from a new Nocardia species. A Gram-positive filamentous bacterium (OFN 14.177T) w...

We consider a basic stochastic particle system consisting ofN identical particles with isotropic k-particle synchronization, k ≥ 2. In the limit when both number of particles N and time t = t(N) grow to infinity we study an asymptotic behavior of a coordinate spread of the particle system. We describe three time stages of t(N) for which a qualitative behavior of the system is completely differe...

Based on linear feedback control technique, a projective synchronization scheme ofN-dimensional chaotic fractional-order systems is proposed, which consists of master and slave fractional-order financial systems coupled by linear state error variables. It is shown that the slave system can be projectively synchronized with the master system constructed by state transformation. Based on the stab...

The general consensus in the N-body community is that statistical results of an ensemble of collisional N-body simulations are accurate, even though individual simulations are not. A way to test this hypothesis is to make a direct comparison of an ensemble of solutions obtained by conventional methods with an ensemble of true solutions. In order to make this possible, we wrote an N-body code ca...

The paper brings a discussion about the source of the inaccuracy in observations of objects and demonstrates that the essential reason of the lack of precision is changeability, and the more changeability, i.e. more dynamics, can be experienced the more inaccurate, more fuzzy judges can be. The space of ordered fuzzy numbers (OFN), the new model of fuzzy numbers that make possible to deal with ...

Arthrobacter sp. BCC 72131, an obligate aerobic bacterium, was used to create anaerobic conditions, and Clostridium beijerinckii TISTR 1461 as a butanol producer in acetone-butanol–ethanol (ABE) fermentation. Sweet sorghum juice (SSJ) medium containing 60 g/L of total sugar supplemented with 1.27 (NH4)2SO4 production (BP) medium. inoculated into the BP 1-L screw-capped bottles. After 2, 4, 6 12...

The biodegradability ofN, N Octadecyldimethylamine, a long-chained aliphatic amine, was studied in a biotreatability system. The study serves as a precursor to the application ofcompost biofiltration to treat odorous waste gases containing long-chained alkyl amines (e.g., emitted by spray-painting operations). The biodegradability ofthe amine was determined by evaluating contaminant removal and...
