Computer-chess programs achieve outstanding results at playing chess. However, no existing program can compose adequate chess problems. In this paper, we present a model that is capable of improving the quality of some of the existing chess problems. We have formalized a major part of the knowledge needed for evaluating the quality of chess problems. In the model, we attempt to improve a given ...
M. Buehler, R. Battaglia, A. Cocosco, G. Hawker, J. Sarkis, K. Yamazaki. Centre for Intelligent Machines, McGill University, Montr eal, QC H3A 2A7, Canada Abstract A simple mechanical design for quadrupedal locomotion, termed SCOUT, is proposed, featuring only one degree of freedom per leg. This paper demonstrates experimentally that our rst prototype SCOUT-1 is capable of walking, turning, and...
The steady-state voltage and [Na(+)](o) dependence of the electrogenic sodium pump was investigated in voltage-clamped internally dialyzed giant axons of the squid, Loligo pealei, under conditions that promote the backward-running mode (K(+)-free seawater; ATP- and Na(+)-free internal solution containing ADP and orthophosphate). The ratio of pump-mediated (42)K(+) efflux to reverse pump current...

Ultimately, decisions about the need for, and volume of, food production from our own land resources are political ones since agriculture, in general, is dependent for a variety of reasons on substantial Government support. This is especially true of the hill areas and although it is difficult to calculate the total expenditure on agricultural support to the hills and uplands since farmers in t...
or 011 getting out of bed is characteristic. The second usually one or two hours later, the third say after breakfast, and the fourth about 10 or II A.M. For the rest of the day the patient is quite well, gets about his daily employment, takes his food with appetite and his exercise with energy. Next day, the same thing is repeated, the days grow into weeks and months before he seeks advice, so...
SIR JOHN HILL (1714-1775), the mid-Georgian entrepreneur, man of letters and science, must have written at least ten times the approximately two hundred letters that survive.' Disappearance of the other nine-tenths is not mysterious: Hill was vilified by most of his contemporaries, who enjoyed little, if any, sense that the documents pertaining to his life could ever be of any interest to poste...
A general hill-climbing attack algorithm based on Bayesian adaption is presented. The approach uses the scores provided by the matcher to adapt a global distribution computed from a development set of users, to the local specificities of the client being attacked. The proposed attack is evaluated on a competitive feature-based signature verification system over the 330 users of the MCYT databas...
