We construct a generating set for the ring of invariants for the four and five dimensional indecomposable modular representations of a cyclic group of prime order. We then observe that for the four dimensional representation the ring of invariants is generated in degrees less than or equal to 2p − 3, and for the five dimensional representation the ring of invariants is generated in degrees less...

Practice shows that increasing the amount of instruction level parallelism offered by an architecture (like adding instruction slots to VLIW instructions) does not necessary lead to significant performance gains. Instead, high hardware costs and inefficient use of this hardware may occur. Mapping embedded applications onto multiprocessor systems forms a very interesting extension to ILP. In thi...

We describe a new algebraic-combinatorial method of public key encryption with a certain similarity to the well known Imai-Matsumoto. We use the general idea to treat vertices of a linguistic graph (see [21] and further references) as messages and use the iterative process to walk on such graph as encryption process. To hide such encryption (graph and walk on it) we will use two affine transfor...

A general method to map the 3D spatial distribution of light emerging from nanoscale apertures is presented that uses photolithographic techniques to create polymer replicas of the intensity distribution. The resulting features varied with aperture diameter and exposure time and showed good correlation with theory. This method provides direct visualization of the intensity distribution in close...

Abstract In this workshop we describe our ongoing work on a prototype presenting heat map data to visually impaired users. We try to reduce the stress level of blind travelers by presenting information about the number of other blind persons who can help with navigation. This is reached by augmentation of the u...

We report on the observation of PSR 2334+61 in the soft X-ray domain with ROSAT. Assuming a power-law spectrum dN=dE / E with photon-index = 2 we derive an X-ray ux of f x = (7:10:2)10 14 erg s 1 cm 2 within the 0:1{2:4 keV energy range. An upper limit for the neutron star's surface temperature is put at T 1 s 1:2 10 6 K for a neutron star with a medium stii equation of state (FP-model with M =...

0. Introduction The tautological rings R(M g,n) are natural subrings of the Chow rings of the Deligne-Mumford moduli spaces of pointed curves: (1) R(M g,n) ⊂ A (M g,n) (the Chow rings are taken with Q-coefficients). The system of tautological subrings (1) is defined to be the set of smallest Q-subalgebras satisfying the following three properties [FP]: (i) R(Mg,n) contains the cotangent line cl...

In recent years Sequential Monte Carlo (SMC) methods have been applied to handle some of the problems inherent to model-based tracking. In this paper two issues regarding SMC are investigated in the context of estimating the 3D pose of the human arm. Firstly, we investigate how to apply a sub-space to representing the pose of a human arm more efficiently, i.e., reducing the dimensionality. Seco...

Traditionally, traces are the sequences of labels associated with paths in transition systems X → P(A×X). Here we describe traces more generally, for coalgebras of the form X → P(F (X)), where F is a polynomial functor. The main result states that F ’s final coalgebra Z ∼= −→ F (Z) gives rise to a weakly final coalgebra with state space P(Z), in a suitable category of coalgebras. Weak finality ...
