The product code of two Reed-Solomon codes can be regarded as an evaluation codes of bivariate polynomials, whose degrees in each variable are bounded. We propose to decode these codes with a generalization of the Guruswami-Sudan interpolation-based list decoding algorithm. A relative decoding radius of 1 − 6 √4R is found, where is the rate of the product code. We also discuss a generalization ...

An important goal for a new communication system is to transfer information at a high rate while keeping energy consumption low. Shannon's channel capacity sets a limit on the tradeoff between the rate of information transfer and the required energy. In this paper the performance of turbo block coding is compared to Shannon's limit for binary communications over a channel with thermal noise. Th...

Systematic reuse of software artifacts can be achieved with software product lines, which represent a family of similar software systems. A variability model, e.g., feature model, describes their commonalities and variabilities and serves as a basis for a product configuration, i.e., the selection of features according to constraints defined in the model. These variability models can contain ad...

In order to protect agricultural product information and copyright, this paper proposes an efficient bar-code watermark system with digital signature. The proposed system adopts digital signature to prevent a buyer from unauthorized copies and to prevent a seller from forged unauthorized copies. The proposed system also encodes the signature with bar-code and embeds the bar-code image into the ...

Vector quantization is known as the best lossy source coding among the fixed-to-fixed coding methods because of its satisfactory ability of expression. Although it can represent any fixed-to-fixed code and has optimization methods that guarantee local optimality, its encoding and optimization require the computation that grows exponential to the data length. We propose an optimization method fo...

Tisane is a beverage infused with herbs instead of tea leaves. The main objective of the study was to formulate and analyse the herbal infusions without any tea leaves and caffeine free alternative to tea or coffee for a hot drink, to perform a sensory evaluation on 2 different herb infusions (tisanes) prepared from formulations of indigenous herbs and spices and to analyse for its biochemical ...

Product channel codes are proposed to protect progressively compressed and packetized images for noisy channels. Within packets, the product code uses the concatenation of a rate compatible punctured convolutional code and an error detecting parity check code. Across packets, Reed-Solomon codes are used. Beneets include exible choice of delay, adaptability of error protection level (i.e., unequ...

The development of software products are often managed through the use of Version Control Systems (VCS). VSCs allow for versioning of source code and manage the process of merging newly developed code into the product primarily through the use of branches. The branching architecture and the development processes used by the product groups are inter-related and have often evolved over many relea...
