Measurement of Frequency Deviation By Using Arduino Uno [PDF]

open access: yesEngineering and Technology Journal, 2015
This studyaims at constructing and implementinga new technique for calculating and correcting the frequency deviation in power systems. Several techniques were used to measure frequency deviation.

Algebraic geometry codes with complementary duals exceed the asymptotic Gilbert-Varshamov bound

open access: yes, 2017
It was shown by Massey that linear complementary dual (LCD for short) codes are asymptotically good. In 2004, Sendrier proved that LCD codes meet the asymptotic Gilbert-Varshamov (GV for short) bound.

Automatic Safety Electronic Saving Box

open access: yesEmitor: Jurnal Teknik Elektro, 2019
In this modern era, many people save valuable items in their house, such as assets (jewelry and money) and important files. Therefore, saving box is the right and effective choice for protecting important goods if robbery or fire occurs someday.

Leaf water shedding: Moving away from assessments based on static contact angles, and a new device for observing dynamic droplet roll‐off behaviour

open access: yesMethods in Ecology and Evolution, 2023
Leaf wettability and drainage characteristics of different taxa are often hypothesised to have emerged as a result of evolutionary selection, perhaps to limit the duration of leaf wetness, or to direct water toward efficiently to the soil and root system,

Observation of accelerating parabolic beams [PDF]

open access: yes, 2008
We report the first observation of accelerating parabolic beams. These accelerating parabolic beams are similar to the Airy beams because they exhibit the unusual ability to remain diffraction-free while having a quadratic transverse shift during ...

New constructions of MDS codes with complementary duals

open access: yes, 2017
Linear complementary-dual (LCD for short) codes are linear codes that intersect with their duals trivially. LCD codes have been used in certain communication systems. It is recently found that LCD codes can be applied in cryptography. This application of

Galois LCD codes over finite fields

open access: yesFinite Fields and Their Applications, 2018
In this paper, we study the complementary dual codes in more general setting (which are called Galois LCD codes) by a uniform method. A necessary and sufficient condition for linear codes to be Galois LCD codes is determined, and constacyclic codes to be Galois LCD codes are characterized.

On the minimum distances of binary optimal LCD codes with dimension 5

open access: yesAIMS Mathematics
Let $ d_{a}(n, 5) $ and $ d_{l}(n, 5) $ be the minimum weights of optimal binary $ [n, 5] $ linear codes and linear complementary dual (LCD) codes, respectively.
