The invention concerns a method for transmitting symbols of non binary error correcting code words via a transmission channel. The method comprises a first modulation associating each code word symbol of p bits with a sequence of at leas 2p chips from 2p possible sequences a second modulation to modulate the phase or amplitude of a carrier signal with the sequences associated with the code words, and a step of transmitting the modulated carrier signal via said transmission channel. According to the invention the first modulation is a spread spectrum modulation of the cyclic code shift keying type using a basic pseudo-random sequence of at least 2p chips, the possible 2p sequences being obtained by a circular shift of the basic pseudo-random sequence and a cyclic prefix is inserted into each symbol to be transmitted.

A method is proposed for managing a parity-check node calculation unit of an error-correcting code decoder having a nrepresentation as a bipartite graph comprising at least one parity-check node, the parity-check node being configured to receive first and second input messages, and to produce an output message, the elements of the input and output messages of the parity-check N node comprising a symbol and a measure of reliability associated with the symbol, the first and second input messages containing lists of elements ordered by their measure of reliability. The method comprises: initializing a plurality of n_(bub )FIFO memories with elements calculated from combinations of elements of the first and second input messages, and iteratively determining the values of the output message.

The invention relates to a method for controlling a check node of a NB-LDPC decoder. The check node receives d_(c) input lists U_(i) and delivers and delivers d_(c) output lists V_(i), with iE[1...d_(c)]. Each input list and output list comprises n_(m) elements and each element of the input or output lists comprises a reliability value associated to a symbol of a Galois Field GF(q) with q>n_(m). The input elements and output elements are sorted according to the reliability values in the lists. The method is a syndrome-based method. The syndromes are sums of d_(c) elements of input lists U_(i). The method comprises a step of syndrome calculation, a step of decorrelation and a step for generating the output list.


Patent

A device for interleaving/deinterleaving digital data delivered by processing elements (P0 . . . Pn-1) suitable for being used both with turbo-codes and with LDPC codes. The device includes memory banks (B0 . . . Bm-1) for storing data coming from or going to the processing elements, an interconnection network (INT) for directing the data between the processing elements and the memory banks, and a control unit (CTRL) for controlling the interconnection network and the memory banks. The control unit (CTRL) includes a calculation circuit (CAL) capable of the online generation of command words for the interconnection network and addressing and control sequences of the memory banks, ensuring conflict-free memory access on the basis of the interleaving rule to be applied, the size of the digital data frames, the number of processing units and memory banks, and the interconnection network.

A cleaning solution obtained from an aqueous solution of alkaline or acid pH which has undergone at least two cleaning and recycling cycles. Each cleaning and recycling cycle includes the successive steps of heating a solution of alkaline or acid pH to a temperature above 50 C., completely cleaning the pipework of equipment fouled with organic deposits using the heated solution, and bringing the solution obtained after the cleaning steps into contact with a clay of at least one of the families selected from smectites, sepiolites, vermiculites and illites. At least one one anionic or cationic flocculating agent is added, followed by precipitation and separation to recover said aqueous solution.

Alcoholism: Clinical and Experimental Research | Year: 2012

Objective: Previous studies have found a link between body tattoos or piercings and risky behavior. However, these studies only examined survey data but not real behavior. Methods: Young men (mean = 20.6 years) and women (mean = 20.2 years) leaving a bar were asked whether they wore tattoos and piercings or not and were requested to breathe into a breathalyzer in order to evaluate their alcohol consumption. Results: It was found that participants with piercings and/or tattoos as well as combined piercings and tattoos revealed higher levels of alcohol consumption. Conclusions: Piercings and tattoos could serve as signs of alcohol consumption for educators, parents, and physicians. © 2012 by the Research Society on Alcoholism.

Previous studies have indicated negative evaluations of women with tattoos. However, a study by Swami and Furnham (2007) showed that tattooed women were rated as less physically attractive but more sexually promiscuous. Given that men interpret women's sexual intent according to their physical appearance, we predicted that women with tattoos would be more favorably approached by men. A temporary tattoo was placed on confederates' lower back, or not, and all confederates were instructed to read a book while lying flat on their stomach on a well-known beach. Two experiments were conducted. The first experiment showed that more men (N = 220) approached the tattooed confederates and that the mean latency of their approach was quicker. A second experiment showed that men (N = 440) estimated to have more chances to have a date and to have sex on the first date with tattooed confederates. However, the level of physical attractiveness attributed to the confederate was not influenced by the tattoo condition. These results were discussed with respect to men's possible misinterpretation of women wearing tattoos and the risks associated with this misinterpretation. © 2013 Springer Science+Business Media New York.

Research has found that the appearance of women’s apparel helps increase their attractiveness as rated by men and that men care more about physical features in potential opposite-sex mates. However, the effect of sartorial appearance has received little interest from scientists. In a series of studies, the length of women’s shoe heels was examined. A woman confederate wearing black shoes with 0, 5, or 9 cm heels asked men for help in various circumstances. In Study 1, she asked men to respond to a short survey on gender equality. In Study 2, the confederate asked men and women to participate in a survey on local food habit consumption. In Study 3, men and women in the street were observed while walking in back of the female confederate who dropped a glove apparently unaware of her loss. It was found that men’s helping behavior increased as soon as heel length increased. However, heel length had no effect on women’s helping behavior. It was also found that men spontaneously approached women more quickly when they wore high-heeled shoes (Study 4). Change in gait, foot-size judgment, and misattribution of sexiness and sexual intent were used as possible explanations. © 2014, Springer Science+Business Media New York.

A method of producing data representing an identifier of a neuron from a cluster of L neurons belonging to a neural network having C clusters. L and C are natural integers of values greater than or equal to two. Each neuron has at least two states. The method includes, for at least one current cluster C_(i): producing a set E of neural states originating from at least one cluster C_(j), ji; producing a set A of coefficients of adjacency between at least one neuron of the current cluster C_(i), and at least one neuron of a cluster C_(j )of the neural network ji; calculating, as a function of the set E of neural states, the set A of adjacency coefficients and, as a function of state(s) of the neurons of the current cluster C_(i), at least one winning neuron N_(G).
