This work proposed a new multiuser detector for DS/CDMA systems constituted by the polynomial MMSE detector followed by a local search algorithm 1-adapt LS (one-adaptive local search), namely the Hybrid 1adapt-LS-MuD. In order to reduce computational complexity inherent to recurrent computation of the cross-correlation matrix inverse in DS/CDMA multiuser detection (MuD), this work introduces fo...

This study reports an adaptation of a parametric echosounder system using 15 kHz as secondary frequency to investigate the angular response of sub-bottom backscatter strength of layered mud, providing a new method for enhanced acoustic detection of buried targets. Adaptions to achieve both vertical (0°) and non-vertical inclination (1– 15°, 30°, 45° and 60°) comprise mechanical tilting of the a...

Flume experiments simulating a 12.5 hour tidal cycle were performed to test the hypothesis that flaser and wavy bedding can be produced in shallow subtidal areas by tidal activity. The effects of clay composition, sand size, total amount of sediment deposited, compaction time, and peak current velocity were investigated. It was found that the resistance of a recently-deposited mud bed to subseq...

This report is based on the interesting clinical case study of a teenage based in India with long standing history of ingesting nonnutritive materials. She was initially non-selective, but later began more exclusively consuming mud obtained from a wall in the back yard of her house on regular basis. She suffered from a eating disorder known as pica. The DSM-IV defines pica as a form of feeding ...

suspended solids % mixed juice levels encountered at diffuser A cane diffuser is a fairly efficient filter, retaining within the bagasse bed much of the suspended material that would otherwise pass into the draft juice. It was decided to investigate the possibility of utilising this filtration capability further by recycling the mud (underflow) from the juice clarification station to the diffus...

Background: Liver-expressed antimicrobial peptide-2 (LEAP-2) is an important component of innate immune system in teleosts. In order to understand isoform-specific involvement and regulation of LEAP-2 genes in mud loach (Misgurnus mizolepis, Cypriniformes), a commercially important food fish, this study was aimed to characterize gene structure and expression characteristics of two paralog LEAP-...

Code division multiple access (CDMA) is used in various radio communication techniques due to its advantages. In CDMA one of the most important processes is multi user detection (MUD). There are numerous methods for MUD in CDMA, but in most of the methods, they identify the exact user but the interference signal is high. One of the methods used for MUD in CDM A is elliptic curve cryptography (E...

Similar to the mechanism by which a visco-elastic mud damps the energy of overpassing surface waves, if the near-shore seafloor is carpeted by an elastic thin material attached to generators (i.e. dampers) a high fraction of surface wave energy can be absorbed. Here we present analytical modeling of the flexible carpet wave energy converter and show that a high efficiency is achievable. Express...

Mercury (Hg) speciation and partitioning have been investigated in a fluid mud profile collected in the high turbidity zone of the Gironde estuary. The formation of the fluid lens generates local and transient oxic-anoxic oscillations following the sedimentation-resuspension tidal cycles under a specific hydrodynamic regime. The total Hg concentration, ranging from 5 to 190 nM, increases with S...

Mycobacterium ulcerans disease (MUD) is rapidly reemerging in many countries, especially in West African countries. Antecedent trauma has often been related to the lesions that characterize this frequently crippling disease. We report here the first case of MUD that followed a human bite at the site where the lesion later occurred.
