  • Publication number: 20170346572
    Abstract: A molecular communication system includes a plurality of molecular transmission nanomachines randomly located in a first space, a molecular reception nanomachine and a molecular transmission channel. The molecular reception nanomachine is located in the first space, and receives at least one information molecule representing first data from an l-th molecular transmission nanomachine to obtain the first data based on the at least one information molecule. The l-th molecular transmission nanomachine is l-th nearest to the molecular reception nanomachine. The molecular transmission channel provides a transmission path for the at least one information molecule moving in the first space based on an anomalous diffusion process. The plurality of molecular transmission nanomachines are scattered in the first space according to a stationary Cox process.

  • Patent number: 9621283
    Abstract: A molecular communication system includes a molecular transmitter, a molecular receiver and a molecular transmission channel. The molecular transmitter transmits at least one molecule representing first data. The molecular receiver receives the at least one molecule, and obtains the first data based on the at least one molecule. The molecular transmission channel is connected between the molecular transmitter and the molecular receiver, and provides a transmission path for the at least one molecule. The at least one molecule moves in the molecular transmission channel based on an anomalous diffusion process. The anomalous diffusion process in the molecular transmission channel is modeled based on a fractional diffusion equation (FDE).

  • Patent number: 7234095
    Abstract: A turbo encoded H-ARQ system and an error detection method are disclosed, and more particularly, a turbo encoded H-ARQ system and an error detection method that lower an undetected error probability and frame error rates by increasing the degree of an equivalent CRC generator polynomial by using a modified trellis termination. It has been made possible to obtain an equivalent CRC generator polynomial having higher degree than the related art CRC generator polynomial by employing a modified trellis termination. This achieved a lower undetected error probability than the related art undetected error probability by using an equivalent CRC generator polynomial having higher degree. This also achieved lower frame error rates, when the same number of overhead bits are used, due to the lower undetected error probability.

  • Publication number: 20070094929
    Abstract: Disclosed is a gasification technique for converting biomass, which is difficult to treat, into clean gas fuel able to be burned in a cogeneration system. The gasification technique includes first stage fluidized-bed catalytic gasification, and second stage gasification of tar and catalytic reforming to convert nitrogen in tar, and HCN in a flammable gas into NH3, unlike conventional gasification techniques. In addition, since the temperature of a total gasification process is lower than a melting point of ash, powdery ash is generated and thus easily treated. Also, little heat is released due to the low process temperature, and therefore, a compact reactor may be designed to produce gas having a high caloric value. Further, the generated tar is recovered and reused in other processes, and the gas fuel contains a small amount of ammonia.

  • Patent number: 7087171
    Abstract: Disclosed herein is a method for dewatering sewage sludge by using sludge-coal-oil co-agglomeration (“SOCA”) which comprises the steps of physically, chemically or biologically conditioning sludge to impart hydrophobicity and lipophilicity to the sludge (conditioning step), supplying oil and coal to the conditioned sludge with stirring to form sludge-coal-oil agglomerates (agglomerating step), enlarging the particle diameter of sludge-coal-oil agglomerates (size enlargement step), and remaining the enlarged sludge-coal-oil agglomerates over a sieve to selectively separate them from hydrophilic materials dispersed in tailing water(screening step). According to the method, since sludge can be rapidly, easily and effectively dewatered and purified when compared to conventional sludge treatment methods. In addition, there is no risk of involving malodor and air pollution. Furthermore, the dewatered sludge can be utilized as a high-quality fuel.
