Wireless capsule endoscopy (WCE) uses a pill size capsule which is easily swallowed by patients. WCE comes with wireless power transmission, allowing images to be recorded into a hard disk for later analysis by a doctor. Automated image analysis algorithms can be used to help doctors detecting abnormal patterns and to identify the various segments of the gastrointestinal tract. This type of ana...

A novel approach to climate forecasting on an interannual time scale is described. The approach is based on concepts and techniques from artificial intelligence and expert systems. The suitability of this approach to climate diagnostics and forecasting problems and its advantages compared with conventional forecasting techniques are discussed. The article highlights some practical aspects of th...

We show that non orthogonal wavelets can characterize the frac tional Brownian motion fBm that is in white noise We demonstrate the point that discriminating the parameter of a fBm from that of noise is equivalent to discriminating the composite singularity formed by superimposing a peak singularity upon a Dirac singularity We characterize the composite singularity by formalizing this problem a...

We study the extent to which, in a laboratory …nancial market, noise trading can stem from subjects’ irrationality. We estimate a structural model of sequential trading by using experimental data. In the experiment, subjects receive private information on the value of an asset and trade it in sequence with a market maker. We …nd that, in the laboratory, the noise due to the irrational use of pr...

RANNALA et al. (2000) develop a useful Poisson proand also simplifies the estimation of p and as described in estimation from the whole sample of hosts. The cess model for estimating allele frequencies in bacterial populations using presence/absence data on inMLEs derived in both of the following sections are shown to be less biased than the estimators given in fected hosts. However, they also ...

There is almost always a cost associated with acquiring training data. We consider the sit­ uation where the learner, with a fixed budget, may 'purchase' data during training. In par­ ticular, we examine the case where observ­ ing the value of a feature of a training exam­ ple has an associated cost, and the total cost of all feature values acquired during train­ ing must remain less than this ...

Longtemps l’École polytechnique a eu pour vocation première de former des ingénieurs appelés à alimenter les corps techniques l’État. La proportion polytechniciens démissionnaires n’a, cependant, cessé d’augmenter, au cours du xxe siècle, devenir systématiquement majoritaire compter milieu années 1980. L&#8...

Granular mixing process is necessary for operation in many industries such as food, pharmaceutical and cosmetic industries. Although the materials are almost first stage production process, it can affect quality cost of final product. They choosing a suitable mixer that may reduce energy consumption. A static device widely used to mix Because phenomena very complex, proper design still needs be...
