Capacitance−voltage characteristics of high quality Pt Schottky diodes fabricated on oxygen-vacancy-doped SrTiO3 single crystals were used to obtain the oxygen vacancy profiles within one microns interface. Computer simulations based solving drift-diffusion equations for electrons and ionized vacancies performed understand experimentally observed profile’s time-evolution at room temperature 0 V applied bias. Building upon this understanding, diode’s profile evolution under −35 bias was...

Oxide‐based resistive switching devices are a leading contender for the next generation memories. Before use, each device has to go through conditioning process called electroformation which been suggested be initiated by accumulation of oxygen vacancies. Here, experimental evidence is presented shows that both Ta 2 O 5‐x ‐ and TiO 2‐x ‐based crossbar devices, exhibit characteristic electronic instability reversible constriction current flow narrow filament prior permanent change. Thus, it...

A major contributor to under-five mortality is the death of children in 1st month life. Intrapartum complications are one causes perinatal mortality. Fetal cardiotocograph (CTGs) can be used as a monitoring tool identify high-risk women during labor.The objective this study was precision machine learning algorithm techniques on CTG data identifying fetuses.CTG 2126 pregnant were obtained from University California Irvine Machine Learning Repository. Ten different classification models...

The shift from special schools towards inclusive education is becoming increasingly prevalent across systems around the world. However, challenges this brings remain critical for developing nations where there a huge chasm between policies and practices. This study used instrumental case design to examine how general teacher strategised her teaching classroom practices while accommodating student with complex learning behavioural disabilities within regular classroom. Data collected through...

As classrooms become increasingly diverse in higher education, educators are emphasising inclusive practices teaching and learning to accommodate the needs of learners. There is also an emerging need for approach assessment accessibility, opportunity, relevance engagement. This study, using design-based research guidelines with student–faculty partnership, designed, developed, implemented evaluated contextually sensitive protocol as fair assessment. Data from students' reflections...

The study of context-based leadership practices has gained currency during the last decade. This aims to complement recent efforts researchers in identifying successful school leaders, and deliberating how these are enacted within their own unique contexts. An in-depth case was conducted a northern Malaysia using combination methods grounded theory. Case were used for data collection from multiple sources, employing semi-structured interview protocol derived one several studies under...

This study investigated the leadership practices of semi-urban middle school leaders in China. A multi-site case was conducted using a qualitative research design, collecting data through interviews with principals, administrators, teachers, and parents, along document scanning, observations, field notes. Qualitative analysis revealed three distinct themes concerning contextual principals. The findings highlighted that these principals implemented identified varying ways, directly responding...

The microstructure of TiO2 functional layers in nanoscale resistive switching devices was analyzed using Scanning Electron and Transmission Microscopies (SEM TEM). as-fabricated were amorphous with very weak lattice fringes High Resolution TEM. After electroformation low power dissipation (PDIS < 0.4 mW), the microstructural changes layer limited to an area approximately 75∼100 nm radius indicating that current path Joule heating localized. Since reset (≈2.4 mW) greater than power,...

This study explores beliefs and classroom practices of teachers from collectivist nations through the lens Hofstede’s cultural dimensions. In this grounded theory study, an in-depth investigation ways in which six five different countries described their was carried out.

Students' perception of assessment methods plays a significant role in determining their effort towards learning and tasks. Similar to the goal orientation predicting students' classroom learning, this study aims examine how orientations influence assessments. Using qualitative research design, data was collected from 41 students enrolled master's degree programme at public university northern Malaysia, using reflection notes semi-structured interviews.

Discourse regarding modern doctoral studies criticises the traditional notion of education as being too narrow to facilitate knowledge creation and transfer towards economy. This study considered pedagogical links supervisory practices enable transformative learning experiences. The study, grounded in student–faculty partnership framework concepts, partnered five senior students with three faculty supervisors for more than a year mentor junior research through variety strategies. Through...

Abstract Transient currents associated with electroforming TiO 2 -based resistive switching devices were measured using three distinct circuits designed to limit them, and they correlated physical changes in the top electrode scanning electron microscopy. A transient current more than 10 times greater expected was observed when only source meter via compliance set point. The large excursion arose from equipment delays resulted significant electrode. An external resistor used decrease excess...

The transient electroforming process of TiO2-based resistive switching devices is investigated using a pulsed voltage method, and the time found to vary from 10−8 s 10−1 as function pulse magnitude (3–8 V) ambient temperature (25–100 °C). Pulsed experiments thermal simulations reveal that Joule self-heating has significant effect on dynamics, specially for voltages above 5.5 V where there little dependence (10–100 ns) much shorter than device constant (≈2 μs).
