Unsupervised Feature Transfer for Batch Process Based on Geodesic Flow Kernel

The problem of misalignment of the original measurement model is caused by nonlinear, time-varying characteristic of the batch process. In this paper, a method based on geodesic flow kernel (GFK) for feature transfer is proposed. By mapping data into the manifold space, the feature transfer from source domain to target domain is implemented....

Autotrophic Nitrogen Removal from Low Concentrated Effluents: Study of system configurations and operational features for post-treatment of anaerobic effluents

On a global scale, sewage represents the main point-source of water pollution and is also the predominant source of nitrogen contamination in urban regions. The present research is focused on the study of the main challenges that need to be addressed in order to achieve a successful inorganic nitrogen post-treatment of anaerobic effluents in the...

Which standards’ characteristics increase system flexibility? Comparing ICT and Batch Processing Infrastructures

Most large Information and Communication Technology (ICT) systems develop in a piece-meal fashion. Their complexity and evolution is difficult to manage. They lack flexibility. This contrasts sharply with system design in the batch-wise processing industry, where flexibility has always had a high priority. In this industry, the S88 standard...

A disturbance management approach to improving the performance of batch process operations

Scheduling of batch processes is a complex task, given the discontinuous nature of batch processes and their particular process characteristics, equipment-dependencies and sequence-dependencies. It has a major influence on the ultimate performance of batch processes. However, the scheduled performance is often not realized because production is...

Study of an attitude acquisition measurement technique using the ESA starmapper: Part I: Executive summary

The study deals with the rotational motion of a spin-stabilized spacecraft equipped with a V-slit sun sensor and the X-slit ESA starmapper. Assuming complete absence of an a priori attitude estimate, it is required to produce a rough estimate of the spacecraft attitude motion. It was assumed that sensor misalignments, external torques and...
