One widely-reported prediction is that the availability of low-cost information on price, specifically the rise of comparison shopping agents, will lead all Internet retailers to charge the same price for mass-produced physical goods and that price will be approximately cost. This prediction is, however, in tension with another prediction – that firms(More)
One-stop provision of services is a major goal of e-government. Often service delivery requires several steps cutting across multiple departments or agencies, each with separate eligibility and other rules, data requirements, and processes. For this complex setting, we develop a tiered, intelligent-agent-based framework called ServiceNet. The layers include(More)
Consistency-based feature selection is an important category of feature selection research yet is defined only intuitively in the literature. First, we formally define a consistency measure, and then using this definition, evaluate 19 feature selection measures from the literature. While only 5 of these were labeled as consistency measures by their original(More)
Two conflicting predictions have emerged regarding the effect of low-cost information on price. The first states that all Internet retailers will charge the same low price for mass produced goods. The second states that Internet retailers will differentiate to avoid intense price competition. Using data collected in April 1999 on the prices of 107 books in(More)
The incorporation of a minor amount of carbogenic nanoparticles into powder compositions imparts remarkable colour-tuneability, without compromising the flowability. In a proof-of-concept demonstration we report the use of these hybrid nanopowders for the visual enhancement of latent fingerprints where they effectively resolve issues arising from poor(More)
Carbogenically coated silica nanoparticles (C-SiO2) exhibit color-tunability and carry great promise for two important forensic applications. First, the C-SiO2 nanopowders are ideal for fingerprint development, yielding strong contrast against multicoloured and patterned backgrounds. Second, spontaneous nanoparticle aggregation leads to non-duplicable,(More)
This work presents a general and simple method to obtain a single multiphase equivalent pi-circuit, suitable for power flow studies that takes the coupling effects into account for any line transposition scheme. The resulting circuit, suitable for use in connection with multiphase power flow programs is obtained from node reduction of all cascaded(More)
In this paper, we present a new method to perform overlapped block motion compensation (OBMC) using the modified Sigmoid window (MSW). The proposed MSW-OBMC method uses a variable weighting function to generate a window in order to maximally reduce the blocky artifacts on the edges of the block under consideration. It can be applied in any block partitioned(More)
