Data explosion is one of the greatest challenges of digital evolution, causing the storage demand to grow at such a rate that it cannot compete with the actual capabilities of devices. The digital universe is forecast to grow to over 175 zettabytes by 2025 while 80% is infrequently accessed ("cold" data), yet safely archived in off-line tape...

The archiving of digital data is becoming very challenging as conventional electronic devices wear out in time leaving at stake any data that has been stored in them. Therefore, data migration is necessary every 5-10 years. Unfortunately, the maintenance and replacement of servers in big data centers is very expensive both in terms of money and...

Rapid technological advances and the increasing use of social media has caused a tremendous increase in the generation of digital data, a fact that imposes nowadays a great challenge for the field of digital data storage due to the short-term reliability of conventional storage devices. Hard disks, flash, tape or even optical storage have a...

– In this paper we present a quantizer based on the Leaky-Integrate and Fire (LIF) neural model. The LIF is the model according to which function the ganglion cells. Ganglion cells are placed in the layer of the retina responsible for the encoding of visual information, before it is transmitted to the brain through the optic nerve. In general,...

This paper aims to build an image coding system based on the model of the mammalian retina. The retina is the light-sensitive layer of tissue located on the inner coat of the eye and it is responsible for vision. Inspired by the way the retina handles and compresses the visual information and based on previous studies we aim to build and...

The exponential growth in the generation of digital information creates a big challenge for data storage given the capacity limitations of conventional storage devices. Recent works have proposed DNA as a means of digital data storage proposing a novel solution for long-term storage. Although having many advantages, DNA storage is a challenging...

Living in the age of the digital media explosion the urge for finding new efficient methods of data storage increases significantly. Existing storage devices such as hard disks, flash, tape or even optical storage have limited durability in the range of 5 to 20 years. Recent studies have proven that the method of DNA data storage introduces a...

Living in the age of data explosion, the research of solutions for efficient long term storage of the infrequently used "cold" data is becoming of great interest. However, even if existing storage systems suggest efficiency in capacity, they are lacking in durability. Hard disks, flash, tape or even optical storage have limited lifespan in the...

The exponential increase of digital data that is being generated every year along with the capacity and durability limits of conventional storage devices are raising one of the greatest challenges for the field of data storage. The use of DNA for digital data archiving is a very promising alternative as the biological properties of...

The continuous exponential increase in the generation of digital information is becoming inconsistent with the capacity and longevity limitations imposed by conventional storage devices which can't be reliable for more than 10-20 years. More precisely, 90% of the data on the internet has been only generated in the last 2 years while 80% of this...

The efficient storage of digital data is becoming very challenging over the years due to the exponential increase in the generation of data which can't compete with the existing storage resources. Furthermore, the infrequently accessed data can be safely stored for no longer than 10-20 years due to the short lifespan of conventional storage...

The aggressive growth of digital data threatens to exceed the capacity of conventional storage devices. The need for new means to store digital information has brought great interest in novel solutions as it is DNA, whose biological properties allow the storage of information at a high density and preserve it without any information loss for...

Over the past years, the ever-growing trend on data storage demand, more specifically for "cold" data (i.e. rarely accessed), has motivated research for alternative systems of data storage. Because of its biochemical characteristics, synthetic DNA molecules are considered as potential candidates for a new storage paradigm. Because of this...

DNA is a promising candidate for data storage due to its high density and long-term stability. However, accessing specific data, known as random access, is challenging. This process uses primers, short DNA segments that act as identifiers. Efficient random access depends on highquality primers, constrained by DNA structure. This paper...

Living in the age of data explosion, the research of solutions for efficient long term storage of the infrequently used "cold" data is becoming of great interest. Recent studies have proven that due to its biological properties, the DNA is a strong candidate for the storage of digital information allowing also data longevity. However the...

The exponential increase of digital data and the limited capacity of current storage devices have made clear the need for exploring new storage solutions. Thanks to its biological properties, DNA has proven to be a potential candidate for this task, allowing the storage of information at a high density for hundreds or even thousands of years....
