A semi-continuous hidden Markov model based on the muluple vector quantization codebooks is used here for large.vocabulary speaker-independent continuous speech recognition in the techn,ques employed here. the semi-continuous output probab~hty densHy function for each codebook is represented by a comhinat,on of the corre,~ponding discrete output probablhttes of the hidden Markov model end the c...

[1] Wetland ecosystems are often characterized by distinct vegetation patterns. Various mechanisms have been proposed to explain the formation of these patterns; including spatially variable peat accumulation and water ponding. Recently, short‐range facilitation and long‐range competition for resources (a.k.a scale dependent feedback) has been proposed as a possible mechanism for pattern format...

Column leach test has been performed to examine the behavior of leaching of sodium, calcium and potassium in landfills. In the column leach apparatus, two different layers of contaminated and uncontaminated soils of different height ratios (ratio of depth of contaminated soil to the depth of uncontaminated soil) are taken. Water is poured from an overhead tank at a particular flowrate to the in...

We present a simple analytic model of the interaction of cold convective downwelling currents with an endothermic phase change. The model describes the ponding and lateral spreading of downflows along the phase transition interface. A simple comparison of the vertical forces on the ponding material provides a necessary condition for a downflow to penetrate the phase boundary. This condition is ...

abstract recharge of aquifers by using wastewater, is one of the important and applicable ways for reusing this valuable water resource, especially in arid and semi-arid regions. as the necessity of local practices for finding the proper management strategies and optimum use of recharge systems (conforming to climate, soil, etc.), a preliminary study was carried out. three physical models were ...

2 TCA, time compression approximation, is a practical and often quite accurate tool to predict 3 postponding infiltration for field applications. A modified approximation (MTCA) can be used 4 just as easily and, in general, will reduce the error by about 50%. This is based on two results: 5 1. After ponding, TCA and MTCA predict very close infiltration rates; and 6 2. MTCA, but not TCA, uses th...

Seasonal weather variations have a profound effect on the integrity of cohesionless soil slopes in Canadian Prairies owing to prevalent semi-arid continental climate. The primary contribution this research is development transient and two-dimensional stability model that fully coupled with hydraulic thermal flows. was used predict factor safety (FS) for two slope geometries (18 m height 26 heig...
