The effect of denormalized schemas on ad-hoc query formulation: a human factors experiment in database design
The information systems literature is rich with studies of database organization and its impact on machine, programmer, and administrative efficiency. Little attention, however, has been paid to the impact of database organization on end-user interactions with computer systems. This research effort …

PClean : Bayesian data cleaning at scale with domain-specific probabilistic programming
… and joined to yield incomplete, dirty, and denormalized datasets. Based on this view, this thesis presents PClean, a unified generative modeling architecture for cleaning and normalizing dirty data in diverse domains. Given an unclean dataset and a probabilistic program encoding relevant …

Higher Radix Floating-Point Representations for FPGA-Based Arithmetic
… calculations which require the support of denormalized numbers. This work shows that higher radix representations lead to more efficient use of FPGA resources. For example, a hexadecimal floating-point adder provides a 30% lower Area-Time product than its binary counterpart, and a …

Separation of n-paraffins by selective adsorption
… whereby the n-alkanes were adsorbed and the denormalized material eluted. The process of adsorption-desorption was carried out isobarically at one atmosphere. A mathematical model has been developed to predict the breakthrough time using the method of characteristics. The results were in a …

Hardware acceleration of Monte Carlo-based simulations
… performances. In particular, the handling of denormalized numbers has a major impact on the FPGA operators. Following the results obtained in that studied, we have discussed and selected a set of features that implies improved performance and reduced resources. This set, has been chosen to …
