Authentication codes were introduced by Simmons in [3]. Many combinatorial structures can be used to construct authentication codes, and interesting combinatorial bounds can be obtained, see e.g. [7], [8] and [9]. We investigate authentication codes arising from generalized quadrangles (GQs), which was first done in [1]. The use of intricated techniques and constructions from the theory of GQs ...

Pulmonary hypertension with severe congestive cardiac failure in children secondary to adenotonsillar enlargement was first reported in the Journal of Paediatrics in 1968. Seven years later Simmons I reported the finding of chronic hypersomnolence and periodic sleep apnoea in patients with upper airway obstruction. Subsequently through the work of Guilleminault 2 and others the obstructive slee...

A multi-scale, moving-window method for local thresholding based on Robust Automatic Threshold Selection (RATS) is developed. Using a model for the noise response of the optimal edge detector in this context, the reliability of thresholds computed at di erent scales is determined. The threshold computed at the smallest scale at which the reliability is su cient is used. The performance on 2-D i...

After recalling current performances of time and frequency standards and their use to establish time scales, their limitations in astronomical observations and studies are considered. For expressing the value of almost all quantities, the accuracy of the frequency standards is su cient. However, an improved stability could nd applications in observation techniques and the departure of realized ...

In complex, dynamic environments, an agent's domain knowledge will rarely be complete and correct. Existing deliberate approaches to domain theory correction are signi cantly restricted in the environments where they can be used. These systems are typically not used in agent-based tasks and rely on declarative representations to support non-incremental learning. This research investigates the u...

When we apply the renormalizable theory of weak interaction1l to the hadron system, we have some limitations on the hadron model. It is well known that there exists, in the case of the triplet model, a difficulty of the strangeness changing neutral current and that the quartet model is free from this difficulty. Furthermore, Maki and one of the present authors (T.M.) have shown2l that, in the l...

We parametrize in a model-independent way possible departures from the minimal Standard Model predictions in the matter sector. We only assume the symmetry breaking pattern of the Standard Model and that new particles are sufficiently heavy so that the symmetry is non-linearly realized. Models with dynamical symmetry breaking are generically of this type. We review in the effective theory langu...
