We develop a new receiver for joint symbol, channel characteristics, and code delay estimation for DS spread spectrum systems under conditions of multipath fading. The approach is based on particle filtering techniques and combines sequential importance sampling, a selection scheme, and a variance reduction technique. Several algorithms involving both deterministic and randomized schemes are co...

Functionalized distyrylbenzene analogs and , bearing a tris-(2-pyridylmethyl)amine-based receptor for Zn(2+), were synthesized by a Horner-Emmons-Wittig coupling reaction. It has been found that Zn(2+) complexation induces changes in the linear absorption spectrum that enhance a nonlinear sequential two-photon absorption of nanosecond pulses at 532 nm. This absorption was also found to depend o...

Note Primary CNS tumors constitute a spectrum of pathological entities each with a distinct natural history that reflects the sequential accumulation of genetic lesions and the deregulation of growth-factor signalling pathways during neoplastic transformation. For simplicity, CNS tumors may be classified as GLIOMAS or NONGLIOMAS (see Table 1 which provides a summary of 2007 World Health Organiz...

The paper applies abstract optimisation principles in the space of measures within the context of optimal design problems. It is shown that within this framework it is possible to treat various design criteria and constraints in a unified manner providing a “universal” variant of the Kiefer-Wolfowitz theorem and giving a full spectrum of optimality criteria for particular cases. The described s...

the nutritional requirements of mammalian embryos changes throughout pre-implantation period, coincident with changes in the secretion of the female reproductive tract. therefore, it has been suggested that sequential culture media may support nutritional requirements for optimal growth of the mammalian embryos. in this study, we investigated the effect of two different concentrations (10 or 10...

use of saline water for irrigation has shown considerable promise. however, its effect on the solubility and bioavailability of native soil nutrients is not well understood. this study was conducted to evaluate the effects of salinity on the behavior of zinc(zn) in calcareous soils. the soil samples with different physiochemical properties were collected from four locations in khorasan province...

Bounds on test sequence length can be used as a testability measure. We give a procedure to compute the upper bound on test sequence length for an arbitrary sequential circuit. We prove that the bound is exact for a certain class of circuits. Three design rules are specified to yield circuits with lower test sequence bounds.

An upper bound is given on the cutoff rate of discrete memoryless channels. This upper bound, which coincides with a known lower bound, determines the cutoff rate, and settles a long-standing open problem.

Spend your time even for only few minutes to read a book. Reading a book will never reduce and waste your time to be useless. Reading, for some people become a need that is to do every day such as spending time for eating. Now, what about you? Do you like to read a book? Now, we will show you a new book enPDFd asynchronous operators of sequential logic venjunction sequention that can be a new w...
