This article demonstrates how multinomial processing tree models can be used as assessment tools to measure cognitive deficits in clinical populations. This is illustrated with a model developed by W. H. Batchelder and D. M. Riefer (1980) that separately measures storage and retrieval processes in memory. The validity of the model is tested in 2 experiments, which show that presentation rate af...

We evaluate and compare the storage efficiency of different sparse matrix storage formats as index structure for text collection and their corresponding sparse matrixvector multiplication algorithm to perform query processing in information retrieval (IR) application. We show the results of our implementations for several sparse matrix algorithms such as Coordinate Storage (COO), Compressed Spa...

This paper studies multiple-deep automated vehicle storage and retrieval systems (AVS/RSs) known for their high throughput performance flexibility. Compared to a single-deep system, AVS/RS has better space area utilisation. However, relocation cycle occurs, reducing the whenever another stock keeping unit (SKU) blocks retrieving SKU. The SKU sequence is undetermined, meaning that arrangement un...

A Markov model is proposed to measure storage loss and retrieval failure in retroactive inhibition. This model generalizes Batchelder and Riefer's (1986) storage-retrieval model to account for retroactive inhibition. Storage loss is assumed to result in a disintegration of clustered items, while retrieval failure is assumed to prevent access to clustered items. The model is tested against data ...
