This work investigates the use of signal analysis technique to extract important features from 12 lead system (electrocardiogram) ECG signal. The real signals used in this study were obtained Selangor Medical Center and also downloaded Internet resources. Lead II is chosen for whole due it representative characteristics identifying common heart diseases. implementation project using Matlab mathematical software (version 6.2) data processing toolbox. cross-correlation analysis....
Abstract The first principle study on structural, electronic, and optical properties of 2D hybrid halide compound (2-AMP)BI 4 (B = Pb, Sn) was analyzed using CASTEP computer code. calculations were performed generalized gradient approximation (GGA) schemes. This aims to look at a few characteristics (2-AMP)SnI as potential replacement for (2-AMP)PbI light absorber in solar cell applications due its toxicity humans the environment. results show that substitution lead (Pb) with tin (Sn) can...
A supercritical technique was proposed to synthesise cerate–zirconate ceramic compound by a high-pressure–high-temperature batch-wise reactor system. TG thermogram of the dried powders for all samples showed three stages weight loss. Each stage is corroborated one or two exothermic peaks as shown in DTG signal. complete thermal decomposition accomplished at ~977 °C 2 h. FT-IR and XRD patterns traces carbonate residue calcined due incomplete combustion intermediate compounds. The presence...
Ceramic materials based on cerate-zirconates have potential application as a solid electrolyte in electrochemical devices such fuel cells and hydrogen sensors. To become good electrolyte, the material must exhibits high density sample with homogenize grain size. In this study, we systematically investigated microstructure of Ba (Ce,Zr)O 3 pellet function sintering temperature. The calcined powder was compressed to using hydraulic press pressure 5 tons for min. Two-step (TSS) process applied...
Ultra-fine powder of Ba (Ce,Zr)O 3 was prepared by a sol-gel method using metal nitrate salts as pre-cursor. The compacted hydraulic press with pressure 45 kg/m 2 for 5 min to produce four different pellets. They were sintered at two temperature profiles two-step sintering (TSS) process. first profile fixed T 1 = 1450°C and the second varies from 1300°C, 1350°C 1400°C, respectively. For comparison, pellet also conventional step (CSS) 1450°C. Scanning electron microscope (SEM) images fracture...
Abstract The application of polymer blends such as epoxidized natural rubber (ENR) and polyvinyl chloride (PVC) in immobilizing titanium dioxide (TiO 2 ) photocatalysts has enticed many researchers. However, the presence limits photocatalytic activity by hindering surface‐active site immobilized TiO . In this study, photoetching treatment with dye was successfully applied on /ENR/PVC (TEP) to enhance photoelectrochemical (PEC) performance. Priorly, a dip coating technique used immobilize...
Carbon doped TiO 2 (C-doped ) photocatalyst was prepared by using polyethylene glycol (PEG) as carbon precursor under calcination process muffle furnace.The modified C-doped immobilized onto a glass plate brush and DSAT method with the optimum measured highest photoactivity detected from photodegradation of reactive red 4 (RR4) dye.The condition denoted C2 consist 0.1 g PEG in 6.5 found where rate ca 0.1545 min -1 it is 2.5 times faster compared unmodified .The presence C-C bond represented...
The first principle study on structural, electronic, and optical properties of 2D hybrid halide compound (2-AMP)BI4 (B= Pb, Sn) was analysed using CASTEP computer code. calculations were performed local density approximation (LDA) generalised gradient (GGA) schemes. This aims to look at a few characteristics (2-AMP)SnI4 as potential replacement for (2-AMP)PbI4 light absorber in solar cell applications due its toxicity humans the environment. results show that substitution lead (Pb) with tin...
The hybrid perovskites of amino(methyl) pyridines (AMP) and lead (II) bromide (PbBr 2 ) were synthesised using a reflux method in 40% hydrobromic acid medium closed-nitrogen condition. structural, chemical optical properties the as-synthesised compounds analysed analytically XRD, FT-IR UV-Vis. Based on XRD analysis, all have distinct evenly spaced diffraction peaks, indicating that they are strongly oriented well-crystallised. presence aromatics primary amines mono-substituted pyridinium...
