Led characteristics

In this study, we propose a novel approach using the oscillation characteristics of the RMS current as the input to machine learning models, combined with the confident learning technique. Using the oscillation characteristics obtained by taking a discrete Fourier transform (DFT) of the RMS current as model input, we aim to reduce the computational requirements of the machine learning models.

Strong urbanization and enormous pressures of urban living and livelihoods have led to different development trends. A portion of urban residents choose to settle in the periphery to enjoy more quality living standard while suffering more mobility cost for work. The paper analyzes the characteristics, causes and solutions of gentrification in Hanoi historic inner under the local urban development context.

In this article, we investigated effect of carrier resin ratio and anti-oxidation additives content on properties of anti-oxidant additives Masterbatchs (MBs). The characteristics were measured by: melt flow index (MFI), morphology (SEM), tensile strength and elongation at break. The results indicated that: increasing LLDPE content in carrier resin led to decreasing mechanical properties, MFI weren’t uniform in MBs. With 80/20 of LDPE/LLDPE ratio, the tensile strength and elongation at break values were highest (21.0 MPa, 680.5 %).

The Nipah and Hendra viruses are highly pathogenic paramyxoviruses that recently emerged from flying foxes to cause serious disease outbreaks in humans and livestock in Australia, Malaysia, Singapore and Bangladesh. Their unique genetic constitution, high virulence and wide host range set them apart from other paramyxoviruses. These characteristics have led to their classification into the new genus Henpaviruswithin the family Para-myxoviridae and to their designation as Biosafety Level 4 pathogens. ...

Several transcription factors with the function of setting the biological clock in vertebrates have been described. A detailed understanding of their nucleocytolasmic transport properties may uncover novel aspects of the regulation of the circadian rhythm. This assumption led us to perform a systematic analysis of the nuclear import characteristics of the different murine PER and CRY proteins, usingXenopusoocytes and HeLa cells as experimental systems.

Introduction to LEDs: How LEDs work + some points. Comparison with other sources of light. LED in communication. Blue &White LED technologies. How they are made? Their application? Brief about blue laser? Stands for light emitting diode. Semiconductor device: p-n junction forward-biased.current emits incoherent narrow spectrum light (due to recombination in transition region near the junction.) Color of the emitted light depends on the chemical of the semiconducting material used. (Near-ultraviolet, visible or infrared.)...
