PERBANDINGAN APLIKASI MENGGUNAKAN METODE CAMELLIA 128 BIT KEY DAN 256 BIT KEY

Jurnal Informatika, 2014
The rapid development of the Internet today to easily exchange data. This leads to high levels of risk in the data piracy. One of the ways to secure data is using cryptography camellia. Camellia is known as a method that has the encryption and decryption

Scalable MoS2/Si Photodiode Arrays From Roll‐to‐Roll Mechanical Exfoliation

Advanced Science, EarlyView.
A dry roll‐to‐roll route transforms mechanically exfoliated MoS2 flake networks into silicon‐integrated photodiode arrays. The MoS2/Si junctions generate photovoltaic output without applied bias, allowing illuminated pixels to locate light spots and reconstruct simple images.

Photoelectric Imaging of the Optically Inactive Charge State of Silicon‐Vacancy Defects in Diamond

Advanced Science, EarlyView.
Although the doubly negative charge state of the SiV center in diamond is predicted to ionize only in the ultraviolet and is therefore considered optically inaccessible, we demonstrate visible‐range photoelectric imaging enabled by a previously unrecognized regime of laser‐assisted tunneling. ABSTRACT The investigation of optically active point defects

Nanoscale Confinement Enhances Ultrafast Demagnetization

Advanced Science, EarlyView.
Next generation spintronics may depend on successfully combining femtosecond spin dynamics with nanoscale device miniaturization. We address this by systematically studying the effect of nanoscale confinement on the femtosecond demagnetization of Iron. By combining ultrafast experiments sensitive to spins, charge carriers, and phonons, we uncover a nm ...

Neuromorphic Optical Tracking and Imaging of Randomly Moving Targets Through Dynamic Dense Scattering Media

Advanced Science, EarlyView.
Vision begins not with images but with change: the retina fires only when something moves, handing the brain a stream of spikes. A neuromorphic imaging system adopts the same strategy—an event sensor that sees like the retina, a spiking network that thinks like the brain—to track and reconstruct fully randomly moving targets through tissue (phantom ...

Methods of accounting the avalanche hazard for the territorial land-use planning in Russia

Лëд и снег, 2019
The legislation of the Russian Federation establishes the need to take into account hazardous natural processes and their parameters in territorial planning, as well as presentation of them in the relevant documentation in the form of maps.

Avalanche LEDs Based on Nanostructured Silicon for Microwave Frequency Range

Доклады Белорусского государственного университета информатики и радиоэлектроники
Development of an efficient light signal source is a basic necessity for the development of silicon photonics. Avalanche silicon light emitting diodes (LEDs) can serve as such a source. The article discusses avalanche LEDs based on nanostructured silicon.

Multiphoton Quantum Reservoirs For Robust Multidimensional Computing

Advanced Science, EarlyView.
Projective measurements reveal hidden multidimensional quantum networks within classical multiphoton fields, enabling robust quantum reservoirs for room‐temperature quantum simulation, prediction, and information processing. These networks transform noisy classical photonic platforms into scalable quantum computational architectures.

Multifunctional Quantum Sensing Using Single Spins in a van der Waals Crystal

Advanced Science, EarlyView.
The work demonstrates a dual quantum sensing of temperature and magnetic field using spin‐complex quantum emitters in hexagonal boron nitride (hBN). Temperature sensing via zero‐phonon‐line shifts and magnetometry via optically detected magnetic resonances, enable simultaneous local thermometry and magnetic‐field measurements.
