This paper studies asymmetric price responses of individual firms, via daily retail prices of almost all gasoline stations in the Netherlands and suggested prices of the five largest oil companies over more than two years. I find that 38% of the stations respond asymmetrically to changes in the spot market price. Hence, asymmetric pricing is not a feature of the market as a whole, but of indivi...

Propositional argumentation systems are based on assumption based reasoning and used for computing arguments which support a given hypotheses Assumption based reasoning is closely related to hypothetical default theories or inference through theory formation The latter approach known as the Theorist frame work has well known relations to abduction and default reasoning In this paper proposition...

Accounting for the fine details of the patterning of co-articulated gestures in time is an important outstanding challenge. We report articulatory data capturing the relative timing of consonantal and final vowel gestures in VCV sequences. The elicitation procedure used ensures that the speech studied exhibits substantial variation in both speaking rate and in the degree of hypo/hyper-articulat...

The study was carried out to ascertain benthic macro-invertebrates checklist in the Cross River, Nigeria and using it for bio-indication of the river quality. A total of 186 benthos specimens were collected. The phylum Insecta was most abundant (96) representing 51.61% of total benthos abundance; followed by Oligochaeta 60 (32.25%), Nemertea 10 (5.37%), Hirudiae 8 (4.3%), Cladocera 6 (3.22%), A...

Assume that n and k are positive integers with n ≥ 2k + 1. A non-hamiltonian graph G is hypo hamiltonian if G − v is hamiltonian for any v ∈ V (G). It is proved that the generalized Petersen graph P (n, k) is hypo hamiltonian if and only if k = 2 and n ≡ 5 (mod 6). Similarly, a hamiltonian graph G is hyper hamiltonian if G−v is hamiltonian for any v ∈ V (G). In this paper, we will give some nec...

This paper deals with the optimisation of collecting the accounts to be charged for a cable television company using of third generation mobile telephony. By using mobile telephony, a dramatic increase in the efficiency, productivity and a considerable saving in the logistic support and staff cost are obtained. The number of processes and participants involved in the proposed system are also cu...

A linear mesh network is considered in which a single user per cell communicates to a local base station via a dedicated relay (two-hop communication). Exploiting the possibly relevant inter-cell channel gains, rate splitting with successive cancellation in both hops is investigated as a promising solution to improve the rate of basic single-rate communications. Then, an alternative solution is...

The level set method provides a natural framework for modelling multiphase phenomena in a Eulerian basis. The method is based on the evolution of the signed distance function from interfaces between phases of the flow, and automatically captures complex topological changes of the free surfaces such as breaking and merging. We present an extension to the level set method for modelling the intera...
