In this paper, we present a new construction and decoding of BCH codes over certain rings. Thus, for a nonnegative integer t, let A0 ⊂ A1 ⊂···⊂ At−1 ⊂ At be a chain of unitary commutative rings, where each Ai is constructed ...

The APIs are becoming increasingly more popular and they play a important role in software development. However, many APIs are large and complex that makes them hard to learn. Among avaliable resources to learn to use an ...

We show that commutative group spherical codes in R(n), as introduced by D. Slepian, are directly related to flat tori and quotients of lattices. As consequence of this view, we derive new results on the geometry of these ...

We present a tree code for simulations of collisional systems dominated by a central mass. We describe the implementation of the code and the results of some test runs with which the performance of the code was tested. A ...

We present a new variable-length encoding scheme for sequences of integers, Directly Addressable Codes (DACs), which enables direct access to any element of the encoded sequence without the need of any sampling method. ...

The objective of this study is to analyze the Codes of Ethics in force in public entities in Chile in the light of the open government principles: transparency, participation and accountability. In order to do so, a sample ...
