Non-orthogonal multiple access (NOMA) communications promise high spectral efficiency and massive connectivity, serving users over the same time-frequency-code resources. Higher data rates connectivity are also achieved by leveraging wider bandwidths at higher frequencies, especially in terahertz (THz) band. This work investigates prospects challenges of combining these algorithmic spectrum ena...

This work focuses on the correction of both the coecient and the right hand side matrices of the inconsistent matrix equations $AX = B$ and $XC = D$ with orthogonal constraint. By optimal correction approach, a general representation of the orthogonal solution is obtained. This method is tested on two examples to show that the optimal correction is eective and highly accurate.

Clearly 2007 is the time to be in Philadelphia – next year’s venue for the Academy of Management Meetings. Although it seems like we just returned from the meeting in Atlanta, planning for the Philadelphia meeting has already started. And it is not too early to start thinking about your participation in the Philadelphia AOM Meetings. The deadline for submitting papers and symposia to the ODC Di...

For a nonlinear functional f , and a function u from the span of a set of tensor product interpolets, it is shown how to compute the interpolant of f(u) from the span of this set of tensor product interpolets in linear complexity, assuming that the index set has a certain multiple tree structure. Applications are found in the field of (adaptive) tensor product solution methods for semilinear op...

In this paper, a new method for the determination of missing values in temporal databases is presented. This new method is based on two projection methods: a nonlinear one (Self-Organized Maps) and a linear one (Empirical Orthogonal Functions). The global methodology that is presented combines the advantages of both methods to get accurate candidates for missing values. An application of the de...

An algorithm for multidimensional nonlinear registration is proposed. The deformation field between two elastic bodies is represented by a multi-resolution separable wavelet. Using a progressive approach that reduces algorithm complexity the registration parameters are recovered in a coarse to fine order. A custom wavelet that approximates threefold orthogonality is developed. The performance o...

R |xα| dμ(x) < ∞ (α ∈ (Z≥0)) and the support of μ has nonempty interior. Let Pn consist of all polynomials p of degree ≤ n such that ∫ Rd pq dμ = 0 for all polynomials q of degree < n. Then Pn has the same dimension ( n+d−1 n ) as the space of homogeneous polynomials of degree n in d variables. Furthermore, the spaces Pn (n = 0, 1, 2, . . .) are mutually orthogonal in L(μ). We call {Pn}n=0 a sy...
