the synthesis of [cu3o(oac)6(h2o)3]cl.ch3oh.6h2o is described. the x-ray crystallographic study of thecomplex revealed an isosceles triangle of copper atoms with a triply bridging oxo atom nearly in the plane of thetriangle. the coordination sphere around each metal center is close to distorted octahedral and the central{cu3(μ3-o)} core is planar. every two copper atoms were connected to each o...
This paper investigates the channel assignment problem of dual-band PCS systems where single-band and dual-band handsets co-exist. Load-balancing channel assignment schemes are proposed to improve the system performance. To balance the loads of both bands, the BSC selects a band to serve a call request of a dual-band handset based on the loads of both bands. In addition, a channel re-assignment...

The Huggins band of ozone is investigated by means of exact dynamics calculations using a new (diabatic) potential energy surface for the (1)B(2) state. The remarkable agreement with the measured spectrum strongly suggests that the Huggins band is due to the two C(s) potential wells of the (1)B(2) state. The vibrational assignment, based on the nodal structure of wave functions, supports the mo...
For the purpose of efficient audio coding at low rates, a new bit allocation strategy is proposed in this paper. The basic idea behind this approach is “Give bits to the band with the maximum NMR-Gain/bit” or “Retrieve bits from the band with the maximum bits/NMR-Loss”. The notion of “bit-use efficiency” is suggested and it can be employed to construct a bit assignment algorithm operated at ban...
A cellular network is often modelled as a graph and the channel assignment problem is formulated as a coloring problem of the graph. In a recent paper [16], we introduced the notion of cellular graphs that models the hexagonal cell structure of a cellular network. Assuming a k-band buffering system where the interference does not extend beyond k cells away from the call originating cell, we pro...
