Socio-religious harmony index instrument indicators for Malaysia

The subject of inter-religious relationship among different religious adherents is crucial in determining social peace and harmony in a multi religious country like Malaysia. The question to what extend the society is susceptible to religious issues remains uncertain. This study will contribute in understanding the Malaysian socio-religious harmony status among the multi-religious adherents through development of the social religious index. To suffice part of this effort, the aim of this study was to develop the socio-religious harmony index instrument which is viable to measure socio-religious harmony level in Malaysia. However, the development of a reliable and valid instrument relies heavily on the quality of the variables or the indicators to be used to measure the index. Hence, the instrument was developed using key informants’ input via experts’ panelist which included selected stakeholders from various backgrounds such as academics, ministry officers, policy makers, non-government organization members, and head or representative of religious groups. To effectively manage the input from the expert panelists, the study adopted Fuzzy Delphi Method (FDM) as main methodology to determine the indicators and sub-indicators (quantitative indicators) to be included in the index instrument questionnaires. Fuzzy Delphi was conducted in two rounds: FDM round 1 to determine the main indicators and FDM 2 to determine the sub-indicators to measure each main indicators. Based on the experts’ consensus, the findings of FDM 1 proposed 22 socio-religious harmony indicators. For FDM 2, based on the indicators, the experts proposed 53 sub-indicators as quantitative indicators to measure each indicators. These indicators and their respective sub-indicators will be used to form the index instrument

Bio-based polycationic polyurethane as an ion-selective membrane for nitrate tapered optical fiber sensors

A novel bio-based polycationic polyurethane as an ion-selective membrane for nitrate sensing was successfully developed. In this work, the intermolecular interactions at active polymeric sites play a primary role in selective nitrate-ion detection. From the experiment, FTIR shows a significant shift from 1543 cm−1 to 1548 cm−1 in N-H bending, indicating that intermolecular interactions occur between the polycationic polyurethane and nitrate. AFM shows that the surface roughness of the polycationic polyurethane decreases from 95.7 nm to 12.2 nm after immersion in nitrate solution. Meanwhile, FESEM images show that the bright area, which represents the hard segment of polycationic polyurethane, decreases after immersion, indicating that the nitrate is interacting with the hard segment of the polycationic polyurethane via intermolecular interaction. Furthermore, EIS shows that the conductivity increases from 2.84 × 10−11 to 5.34 × 10−11 S cm−1 after ion exchange occurs between the iodide and nitrate on the polycationic polyurethane. To assess the sensing performance, the sensor probe is fabricated by coating the polycationic polyurethane thin film on the tapered region of an optical fiber. Rapid detection, good repeatability, and a sensitivity of 5.94 × 10−2µW/ppm are obtained for nitrate detection using the above bio-based-sensing material. The selectivity study also shows that the sensing material possesses high affinity toward the nitrate ion

High-gain PDMS-magnetite zero refractive index metamaterial antenna for Vehicle-to-Vehicle communications

This paper presents the simulation design of a high-gain antenna using zero refractive index fishnet metamaterial (MTM) perforated on PDMS-Magnetite substrate for vehicle-to-vehicle (V2V) communications. In order to design the MTM, magnetite nanoparticles, 10-nm iron oxide (Fe3O4) are dispersed into polydimethylsiloxane (PDMS) matrix. Subsequently, the unit cell is designed by removing the circular hole with radius of 3.69 mm on the PDMS-Magnetite substrate layer and arranged in 5×5 array fishnet configuration. This optimized MTM is inserted between the antenna design and pure PDMS substrate to improve the gain. The characteristic of the respective unit-cell is investigated to operate at 5.9 GHz and the effectiveness of MTM is performed by comparing the antenna performance with and without MTM. The unique characteristics of zero refractive index transform the diverging wave into plane wave for perfectly parallel wave impact on the design to improve the directivity and gain of the antenna. The proposed MTM into design improves the antenna gain to 7.36 dB without having to compromise other antenna parameters of return loss, Voltage Standing Wave Ratio (VSWR), gain, directivity, efficiency, current distribution, radiation pattern and bandwidth. These advantages has made proposed antenna as a suitable candidate for V2V in Dedicated Short Range Communication (DSRC) application since high-gain directional antenna is required to increase the sensitivity towards signals coming from certain direction

Mode-locked pulse generation in erbium-doped fiber laser by evanescent field interaction with reduced graphene oxide-titanium dioxide nanohybrid

In this work, a new nanohybrid saturable absorber (SA)is successfully fabricated from reduced graphene oxide (rGO)nanosheets and titanium dioxide (TiO2)nanoparticles. The nanohybrid material is synthesized using the simple and inexpensive hydrothermal technique. The SA is fabricated by depositing the nanohybrid solution onto a D-shaped fiber in an erbium-doped fiber (EDF)laser cavity. The evanescent wave interaction between the incident light and rGO-TiO2 nanohybrid material induces mode-locking in the EDF laser at the threshold pump power of 100.80 mW. A stable soliton pulse with a center wavelength of 1560.45 nm and 3-dB bandwidth of 2.47 nm is obtained. The generated pulses have a repetition rate and pulse width of 11.19 MHz and 1.05 ps at the highest pump power of 268.10 mW. The proposed rGO-TiO2 nanohybrid of this work is a promising SA material for generating mode-locking in an EDF laser for optical modulation applications. © 201
