In this paper, we investigate the benefits of applying a form of network coding known as random linear coding (RLC) to unicast applications in disruption-tolerant networks (DTNs). Under RLC, nodes store and forward random linear combinations of packets as they encounter each other. For the case of a single group of packets originating from the same source(More)
Microcystins are cyanobacterial toxins that are problematic for water authorities due to their resistance to conventional water treatment. Granular activated carbon (GAC) filtration has been shown to be effective in removing microcystin from water using both adsorption and biodegradation removal mechanisms; however, little is known regarding which removal(More)
We describe a rare primary mixed granular cell astrocytoma and fibrosarcoma neoplasm, occurring in a 52-year-old female, with morphologic, immunohistochemical and molecular genetic features, whose tumor was entirely composed of granular cells and fibrosarcoma competent. This represents, to the best of our knowledge, the first report of the mixed granular(More)
In this paper, we investigate the problem of determining the routing that minimizes the maximum/average delivery time or the maximum/average delivery delay for a set of packets in a deterministic Delay Tolerant Network, i.e. in a network for which all the nodes’ transmission opportunities are known in advance. While the general problem with multiple sources(More)
The Chui-Lian multiwavelet family of approximation order three is extended to serve as a basis for an orthogonal discrete multiwavelet transform on the interval. This requires, in addition to the original symmetric and antisymmetric pairs of scaling functions and wavelets, four new functions of each type at each edge of the interval, i.e., one more than(More)

We proposes an mammogram enhancement technique using interpolating distributed approximating functional (DAF) wavelets, visual group normalization (VGN), softer logic masking (SLM) filtering, and nonlinear sharpening enhancement (ESE) techniques. These are formulated to normalize the wavelet coefficients, remove perceptual redundancy and obtain optimal(More)
