Considering the characteristics and location information of nodes in sensor networks, a modified directed transfer model of sensor networks and a new distributed data aggregation model based on “area” are proposed. On the basis of these new models, a novel mixed entropy data compression algorithm based on interval wavelet transforming is proposed for sensor network, according to the characteris...

This paper studies the performance of pipeline network coding for multicast stream distribution in high loss rate MANET scenarios. Most of the previous network coding implementations have been based on batch network coding, where all blocks in the same batch are mixed together. Batch coding requires that the entire batch is received before decoding at destination. Thus, it introduces high decod...

Classical automated theorem provers can prove non-trivial mathematical theorems in highly specific settings. However they are generally unable to cope with even moderately difficult theorems in mainstream mathematics. While there are many reasons for the failure of the classical search-based paradigm, it is apparent that mathematicians can cope with long and complex proofs and have strategies t...

Infants might be better at teasing apart dialects with different language rules when hearing the dialects at different times, since language learners do not always combine input heard at different times. However, no previous research has independently varied the temporal distribution of conflicting language input. Twelve-month-olds heard two artificial language streams representing different di...

SUMMARY Results are repvted of tests on a two-dimensional combined external/internal compressIon Intake having a design Mach number of 2.2. The particular parameters investigated in the tests now reported are:-(a) sidewall bleed, (b) a 3 to 1 range of free stream Reynolds number, (cl the length of subsonic diffuser, Cd) sidewalls out back to the line of the second ramp shock. The maximum pressu...

Inputs of leaf litter and other organic matter from the catchment exceed autochthonous production and provide an important food ,resource in most streams (WEBSTER & MEYER 1997, ANDERSON & SEDElL 1979). An experimental long-term exclusion of terrestrial litter inputs to a forested headwater stream (WALLACE et al. 1997) provided an opportunity to determine if the food quality of organic matter wo...

Ohletz [1] described a mixed signal circuit architecture which can be reconfigured to allow built-inself-test of both analogue and digital parts. In testing the analogue section an on board test signal can be generated from digital components, the analogue test output fed through an A-D converter and the resulting digital bit stream used as the input to a digital signature analyser. Clearly suc...

Firefighting activities regarding buildings normally require electric power to be disconnected before a water jet is used, in order to minimize the risk of electrocution. As for as concerns Photovoltaic Systems, during a fire event it is not possible to turn off the whole power system in order to guarantee that all the components are de-energized. The object of this paper is to estimate the saf...
