Methods and challenges of experimental system identification of a distillation column
… but is currently without a feedback control system. An eventual goal of developing such a control system requires that the behavior of the column be understood. It is necessary to identify which of the column parameters can change, either ones that change to cause a disturbance, or ones that …

Roles of the MicroRNA miR-31 in tumor metastasis and an experimental system for the unbiased discovery of genes relevant for breast cancer metastasis
… human carcinomas. In addition, a novel experimental system for the unbiased identification of metastasisrelevant genes was described. The utility of this system was demonstrated in an initial proof-of-concept screen, which implicated RhoJ as a previously unappreciated modulator of cell …

Design of an optimised fed-batch process for insulin precursor production in Pichia pastoris
… produce the insulin precursor, was used as the experimental system in this study in order to optimise the insulin production process. The experimental system developed in this study employed a two-stage fed-batch feeding strategy in which growth was optimised by feeding glycerol to boost biomass …

Resonant Forcing of Nonlinear Systems
… in which not all of the degrees of freedom in an experimental system are accessible to forcing. We find that certain Lagrange multipliers take on a fundamental physical role as the efficiency of the forcing function and the effective forcing experienced by the degrees of freedom which are not …

Data transmission by frequency-hopped multilevel frequency shift keying
Spread spectrum systems make use of radio frequency bandwidths which far exceed the minimum bandwidth necessary to transmit the basic message information.These systems are designed to provide satisfactory communication of the message information under difficult transmission conditions. …

An ultrafast thermal emission spectrometer for investigating temporal thermal emission of metal thin-films and their reactive derivatives
An experimental system was constructed for studying the reaction of nanolaminate thermites in both the temporal and spectral domains. 1mJ pulses from a Ti:Sapphire laser, stretched to 10ps, were focused onto sample films affixed to glass slides. The emission generated by the ablation of the films …
