In this paper, we intend to solve special kind of ordinary differential equations which is called Heun equations, by converting to a corresponding stochastic differential equation(S.D.E.). So, we construct a stochastic linear equation system from this equation which its solution is based on computing fundamental matrix of this system and then, this S.D.E. is solved by numerically methods. Moreo...

In this study, the combustion of olive byproducts was investigated using TG-FTIR technique. Different types biomass were considered: twigs, leaves, olive-mill waste from two-phase decanting method, and wastewater three-phase system. The reaction regions, ignition, burnout temperatures at different heating rates determined TG/DTG analysis thermogravimetry results. Comprehensive combustion, burno...

The present investigation deals with the thermogravimetric analysis of bamboo and biochar in an inert environment at 10, 20, 30 °C/min. In addition, vacuum pyrolysis was used for biochar. FWO (Flynn–Wall–Ozawa) KAS (Kissinger–Akahira–Sunose) methods were to determine thermodynamic kinetic parameters within active zone. Thermal degradation biomass undergoes several steps loss mass, including moi...

The study delves into the kinetics of non-isothermal crystallization Poly (ɛ-caprolactone) (PCL) and MgO-incorporated PCL nanofibers with varying cooling rates. Differential Scanning Calorimetry (DSC-3) was used to acquire information investigate behavior two types under different rates ranging from 0.5–5 K/min. results show that rate decreases at higher temperatures. Furthermore, parameters we...

Abstract In the current work, a new variation of FeSiBPCu system with good glass forming ability and soft magnetic properties was developed investigated. The effect copper addition on FeSiBP base alloy studied in (Fe 0.77 Si 0.08 B 0.1 P 0.05 ) 100-x Cu x = 0, 0.25, 0.5, 0.75 1.0 at%. Microstructural evolution upon annealing process evaluated by XRD TEM, revealing formation α-Fe(Si), Fe 2 3 (B,...

The influence of mechano-ultrasonic activation (MUA) and nano-additives (carbon nanotubes-CNT) on the interaction pathway nickel–aluminum powder mixture at high heating rates was investigated. optimum conditions activation, along with phase structure formation peculiarities nickel–aluminum–carbon nanotubes mixtures by thermal analysis method, so-called high-speed temperature scanner (HSTS), wer...

won{gil park [won{gil park, j. math. anal. appl., 376 (1) (2011) 193{202] proved the hyers{ulam stability of the cauchy functional equation, the jensen functional equation and the quadraticfunctional equation in 2{banach spaces. one can easily see that all results of this paper are incorrect.hence the control functions in all theorems of this paper are not correct. in this paper, we correctthes...

To ascertain the potential of various leguminous biomass such as L. leucocephala, C. proliferus, P. alba and S. sesban, both energetic a source high added value products, pyrolytic behaviour was studied at different heating rates by using analytical method thermogravimetric (TG), isoconversional Kissinger-Akahira-Sunose (KAS), determination some thermodynamic parameters pyrolysis-gas chromatogr...
