Criteria weights play a crucial role in Multi-Criteria Decision Making (MCDM) problems when selecting the best alternative from set of options. This study aims to compare three objective weighting methods: MEthod based on Removal Effects (MEREC), Entropy, and Symmetry Point Criterion (SPC). These methods were applied case involving ranking eight sustainable energy development alternatives, each characterized by seventeen criteria. Four representative MCDM methods, Simple Additive Weighting...
In this study, vinyltrimethoxysilane-treated hydroxyapatite (vHAP) and PMMA-grafted HAP (gHAP) were successfully prepared from original (oHAP). Three kinds of (oHAP, vHAP g HAP) used as additives for the preparation three groups HAP-modified PMMA bone cements (oHAP-BC, vHAP-BC gHAP-BC). The setting, bending compression properties conducted according to ISO 5833:2002. obtained results showed that maximum temperature while curing (HAP-BCs) decreased 64.9 60.8 °C setting time increased 8.1 14.0...
In this study, new types of gel polymer blend electrolytes (GPBEs) were prepared with the synthesized PVC-g-PMMA graft copolymer, PMMA, plasticizers (propylene carbonate (PC), dioctyl phthalate (DOP)), and different loadings Mg(ClO4)2 via solution casting method using tetrahydrofuran as solvent. Fourier transform infrared (FTIR) spectra showed mutual molecular interactions between organic moieties. The scanning electron microscopy images GPBEs their wrinkled surface morphology due to low...
Abstract The 3D printing PMMA/ZrO 2 filaments with a diameter of 1.75 ± 0.05 mm were fabricated by using single‐screw extruder at temperatures four heating zones 190, 200, 210, and 210°C. Testing samples prepared from the extruded fusion deposition modeling printer Haake MiniJet piston injection molding machine. Fourier transform infrared spectroscopy, mechanical properties, field emission scanning electron microscopy (FESEM), differential calorimetry, thermogravimetric analysis...
Abstract This paper presents the modification of chitosan with polyphenols and application modified in storage tomatoes fruits. The ascorbic acid was used as a initiator for reaction. content varied from 5 to 20 wt.% comparison weight. Some methods techniques were characterize including infrared (IR) spectroscopy, DPPH assay inhibition zone diameter by diffusion agar. obtained results showed that successfully polyphenols. samples have good antioxidant activity against E. coli , S. Aureus, C....
Electrolyte films based on poly(methyl methacrylate) (PMMA), poly(vinyl chloride) (PVC) were prepared by using casting method with the addition 100 wt.% to 240 of dioctyl phthalate (DOP), propylene carbonate (PC) as plasticizers and Mg(ClO4)2 an electrolytic salt. The Fourier infrared spectra (FTIR), tensile, electrical properties, surface morphology electrolyte investigated. FTIR plasticized PMMA/PVC blends indicated that there secondary interactions between matrix. There also molecular...
Globally, the trend of green credit growth has been developing for a long time through projects focusing on energy saving, renewable energy, and clean technology, aimed at achieving economic while protecting environment. In Vietnam, recognizing importance credit, in March 2015, State Bank Vietnam (SBV) issued Directive No. 03/CT-NHNN to promote manage environmental social risks activities. Additionally, SBV Action Plan Banking Industry implement National Strategy Green Growth until 2020,...

In this paper, a new method based on Sum Product algorithm (SPA) using stopping node to reduce computing complexity Low Density Parity Check Codes (LDPC) decoding algorithms is presented. We show how make early decisions calculation of the next iteration. Simulation results that performance iterative for LDPC codes can up 10 times computational with maintaining quality level.
Abstract Some low‐ppm concentrations of Cu II complex catalyst (15, 30 and 60 ppm) were used for synthesis 4‐arm star PMMA (4sPMMA) via Atom Transfer Radical Polymerization using Activators Regenerated by Electron approach (ARGET ATRP). CuBr 2 /pentamethyldiethylene triamine tin(II) 2‐ethylhexanoate as a reducing agent, respectively. Characterization 4sPMMA samples was performed conversion measurement, Fourier transform infrared spectroscopy, nuclear magnetic resonance gel permeation...
Recently, precoded orthogonal frequency division multiplexing (Precoded-OFDM) system was proposed to overcome spectral nulls in inter-symbol-interference (ISI) channel and reduce the overhead of cyclic prefix (CP). The Precoded-OFDM inserts (M-K) zeros between each two set K consecutive information symbols, which can utilize diversity remove nulls' impact at receiver side. However, due inserting symbols sequence, average transmitting power is reduced while peak remains same. Hence, has bad...
