Selectivity and random-access in automatic analysers

Progress in automation in clinical chemistry hasfeatured in recent years a change from rigid to very flexible instruments. The latest instruments are able to perform on each sample only those tests requested, and often do so in a random sequence. The technological aspects of this progress in instrument design are described in this paper (these include computerization ofanalytical steps, multipl...

Organizational aspects of selective analysers

It was intended that this symposium should provide information to assist laboratory staff to understand a few of the characteristics of analytical systems. This paper will concentrate on the importance of sample identification and bi-directional interfacing, the relative merits of selectivity against batch selectivity, a review of the quality-control needs of the newer analysers, and, finally, ...

Deep Mixtures of Factor Analysers

An efficient way to learn deep density models that have many layers of latent variables is to learn one layer at a time using a model that has only one layer of latent variables. After learning each layer, samples from the posterior distributions for that layer are used as training data for learning the next layer. This approach is commonly used with Restricted Boltzmann Machines, which are und...

Cleanly combining specialised program analysers

Automatically proving that (infinite-state) software programs satisfy a specification is an important task, but has proved very difficult. Thus, in order to obtain techniques that work with reasonable speed and without user guidance, researchers have typically targeted restricted classes of language features, programming idioms and properties. We have designed a system in which several of these...
