Motivated by applications to DNA-storage, flash memory, and magnetic recording, we study perfect burst-correcting codes for the limited-magnitude error channel. These are lattices that tile integer grid with appropriate ball. We construct two classes of such correcting a single burst length 2, where each affects corresponding position increasing it one, both cyclic non-cyclic bursts. also prese...

Performance of low-density parity-check (LDPC) codes with maximum likelihood decoding (MLD) for solid burst erasures is discussed. The columns of the paritycheck matrix of LDPC codes are permuted to increase the distance between elements (DBEs) which are defined as a number of symbol positions between elements 1 at each row of the parity-check matrix. The column permutation method can change th...

The pulse-burst duration of a compact burst-mode Nd:YAG laser is extended by one order of magnitude compared to previous flashlamp-pumped designs by incorporating a fiber oscillator and diode-pumped solid-state amplifiers. The laser has a linewidth of <2 GHz at 1064.3 nm with 150 mJ per individual pulse at 10 kHz. The performance of the system is evaluated by using the third-harmonic output at ...

background: municipal solid waste (msw) is the natural result of human activities. msw generation modeling is of prime im­portance in designing and programming municipal solid waste management system. this study tests the short-term pre­diction of waste generation by artificial neural network (ann) and principal component-regression analysis. methods: two forecasting techniques are presented in...

In this paper, we analyze the behavior of the Weighted Decision Feedback Equalizer (WDFE), mainly from filtering properties aspects. This equalizer offers the advantage of limiting the error propagation phenomenon. It is well known that this problem is the main drawback of Decision Feedback Equalizers (DFEs), and due to this drawback DFEs are not used very often in practice in severe channels (...

The burst suppression pattern in clinical electroencephalographic (EEG) recordings is an important diagnostic tool because of its association with comas various etiologies, as hypoxia, drug related intoxication or deep anesthesia. detection bursts and the calculation burst/suppression ratio are often used to monitor level anesthesia during treatment status epilepticus. However, manual counting ...

Center for Wireless Communications, University of California San Diego, 9500 Gilman Dr. La Jolla, CA 92093-0407, USA – fax: +1-619-534-2486 – e-mail: fzorzi,[email protected] Abstract— In this paper, we study the performance of a simple ARQ error control strategy for delay-constrained data communications over a bursty channel in the presence of instantaneous feedback. Correlated errors are mode...

The leukocyte response integrin (LRI) is a phagocyte integrin which recognizes the basement membrane protein entactin and the synthetic peptide Lys-Gly-Ala-Gly-Asp-Val (KGAGDV). The function of LRI is intimately associated with that of a distinct membrane protein, integrin-associated protein (IAP), as antibodies which recognizes IAP can inhibit all known functions of LRI. When adherent to surfa...

the present research has been conducted to investigate the soda and soda-anthraquiuone pulping from whole kenaf (v36). in this respect, anatomical characteristics of kenaf bast and core fibers as well as the soda and soda-aq pulp properties produced at four sodium hydroxide concentrations, namely 25, 30, 35 and 40 (g/lit), have been evaluated. the pulping results indicated that pulp yield and k...
