Due to the aging population increase, the concern for the elderly assistances of each equipment becomes to be necessary. Steps so far taken to assist the aging population have often been limited to visual considerations, such as stronger contrasts or larger characters on the displays and printing, or such physical characteristics as the ease for pressing buttons. However, the issues associated ...
Among the congenital otocephalic syndromes, the term "first and second branchial arch syndrome" designates, in the United States, a characteristic congenital malformation which is usually unilateral but occasionally bilateral. In the German literature, the deformity has been termed "dysostosis otomandibularis". Caronni (1971) has coined the term "auriculobranchiogenic dysplasia". Stark and Saun...

This paper raises the issue of ergonomics' role in giving primacy to fully rational individual human actors in the creation of system failure, despite its commitment to see action as constrained by design and operational features of work. Reflecting on recent contributions to the journal, ergonomics' dilemma is considered against Enlightenment assumptions about individual human reason as the ro...
The dynamics of the rule 54 one-dimensional, two-state cellular automaton (CA) are a discrete analog of a space-time dynamics of excitations in a nonlinear active medium with mutual inhibition. A cell switches its state 0 to state 1 if one of its two neighbors is in state 1 (propagation of a perturbation), and a cell remains in state 1 only if its two neighbors are in state 0. A lateral inhibit...
We present strong evidence for the existence of a supercluster at a redshift of z = 0:54 in the direction of Selected Area 68. From the distribution of galaxies with spectroscopic redshifts we nd that there is a large over-density of galaxies (a factor of four over the number expected in an unclustered universe) within the redshift range 0:530 < z < 0:555. By considering the spatial distributio...
We have obtained a 20 ks observation of PSR 0355+54 using the ROSAT PSPC. The pulsar is detected with a count rate of 4:2(1:3) 10 ?3 s ?1 above the background. While the 70 source counts are insuucient for spectral tting, we have derived source parameters for speciic cases of power law as well as blackbody spectra. For a Crab-like spectrum (photon index = 2) we nd L x (0:1 ? 2:4 keV) = 1:0 10 3...
Temporally extended goals (TEGs) refer to properties that must hold over intermediate and/or final states of a plan. Current planners for TEGs prune the search space during planning via goal progression. However, the fastest classical domain-independent planners rely on heuristic search. In this paper we propose a method for planning with propositional TEGs using heuristic search. To this end, ...
