Purpose – This study aims to report the extent of voluntary carbon emission disclosures by major Australian companies during years 2006 2008. paper provides contemporary data and explanations about emissions reporting in Australia. Additionally, determine variables that explain disclosures.
Abstract Manuscript Type Empirical Research Question/Issue How does corporate governance affect a manager's intention to promote social responsibility ( CSR )? Is the relationship between financial transparency and activities affected by business group affiliation ownership structure of firms? Findings/Insights ratings are negatively correlated with level earnings management when all firms considered. However, is weaker for chaebol highly concentrated ownership, which suggests that practices...
Ultraviolet (UV) photodetectors based on ZnO nanostructure/graphene (Gr) hybrid-channel field-effect transistors (FETs) are investigated under illumination at various incident photon intensities and wavelengths. The time-dependent behaviors of FETs reveal a high sensitivity selectivity toward the near-UV region wavelength 365 nm. devices can operate low voltage show excellent selectivity, responsivity (RI ), photoconductive gain (G). change in transfer characteristics UV light allows to...
Fast recovery, high sensitivity, selectivity, and room temperature (RT) sensing characteristics of NO gas sensors are essential for environmental monitoring, artificial intelligence, inflammatory diagnosis asthma patients. However, the conventional semiconductor-type have poor that need to be solved, such as slow recovery speeds (>360 s), low sensitivity (3.8), operating temperatures (>300 °C). We propose here a memristor-based sensor gasistor (gas + memory resistor) with SnO2, Ta2O5, HfO2...
The detection speed of a memristor-based gas sensor (gasistor) is limited because it detects passing through the top electrode (TE). In this work, to enhance response characteristics nitric oxide (NO) for hafnium dioxide (HfO2)-based gasistor, we propose use porous carbon nanotube (CNT) and N-[3-(trimethoxysilyl)propyl]ethylenediamine (en-APTAS) familiar with NO. First, CNT as TE provides approximately five times more sensitivity 50-ppm NO than that conventional metal-TE. Also, when...
Abstract Designing a transparent carbon nanotube (CNT) gas sensor for nitrogen dioxide (NO 2 ) detection at room temperature (RT), which is unaffected by humidity, critical challenge in various technologies. To solve this issue, filament‐based memristor heater (MH) embedded low‐power CNT proposed to address humidity‐related issues, and dynamic response with low power consumption of 6.15 µW swift recovery <1 ms/30.8 successfully demonstrated, without any serious effects on humidity. This...
Oxygen (O2) sensing in trace amounts and mixed gas is essential many types of industries. Semiconductor sensors have proven to be invaluable tools for the O2 measurements a wide concentration range, but are only able quantify range subppm, thus far, especially gas. We present this paper new concept with incomparable sensitivity using IGZO-films oxygen vacancy-based conducting filaments (CFs). relies on rupturing CFs, proposed device quickly recovers initial state pulse 0.6 V/90 μs after...
We deal with a cost-based adaptive handover hysteresis scheme for the horizontal decision strategies, as one of self-optimization techniques that can minimize failure rate (HFR) in 3rd generation partnership project (3GPP) long-term evolution (LTE) system based on network-controlled hard handover. Especially, real-time operation, we propose an simplified cost function considering some dominant factors closely related to HFR performance such load difference between target and serving cells,...
Memristor-based gas sensors (gasistors) have been considered as the most promising candidate for detecting NO suitable neural network (NN) analysis. In this work, in order to solve an overfitting issue arising from training data when using a single gasistor, which degrades accuracy of NN, we here propose metal–insulator-silicon (MIS)-structured Zr3N4-based gasistor array that results improvement both NN analysis and efficiency operating power. As result, proposed showed decrease epoch 2.5%...
Abstract Memristor-based gas sensors (gas sensor + memristor, gasistor) have gained popularity due to their high response characteristics and ability operate at RT. In this paper, N -[3-(Trimethoxysilyl)propyl]ethylenediamine (en-APTAS), a commonly used membrane for NO x sensors, is applied in the gasistor with carbon nanotubes (CNTs)-top electrode (TE). As result, we demonstrated time was reduced by 104 s, 10 ppm Nitric oxide (NO) increased 3.69, indicating an enhanced sensing property...

The an RS BE, exhibited low forming voltages (0.8 V) stable resistive switching behavior, high endurance on/off ratio of about 125. This improvement due to the better control electric field distribution oxygen vacancy concentration when applying BE memristors. Maintaining stability conducting...
