the effects of operating parameters such as feed temperature and permeate-side pressure on the performance of a commercial pva membrane in the dehydration of toluene by a pervaporation (pv) membrane system is studied in the present work. the results obtained indicate that increasing temperature in the range of 40 to 70 °c and reducing permeate pressure in the range of 1 to 10 mmhg increase memb...

This paper proposes an adaptive sensorless finite-control-set model predictive control (FCS-MPC) method for the interior permanent magnet synchronous motor (IPMSM). The is feasible in full speed range from zero to flux-weakening region above rated speed, without transition between low and high speeds. A ripple excitation-based position estimation proposed extract rotor-saliency-based informatio...

The MYTHEN single-photon-counting (SPC) detector has been characterized using the time-over-threshold (ToT) readout method, i.e. measuring the time that the signal produced by the detected X-rays remains above the comparator threshold. In the following it is shown that the ToT readout preserves the sensitivity, dynamic range and capability of background suppression of the SPC mode, while enhanc...

The short pulse duration, small effective source size and high flux of synchrotron radiation is ideally suited for probing a wide range of transient deformation processes in materials under extreme conditions. In this paper, the challenges of high-resolution time-resolved indirect X-ray detection are reviewed in the context of dynamic synchrotron experiments. In particular, the discussion is ta...

Many of the adaptive watermarking schemes reported in the literature consider only local audio signal properties. Many schemes require complex computation along with manual parameter settings. In this paper, we propose a novel, fuzzy, adaptive audio watermarking algorithm based on both global and local audio signal properties. The algorithm performs well for dynamic range of audio signals witho...

�e correlation between increasedWest African monsoon rainfall and anomalously low surface pressure over the Sahara is well established in observations and global climatemodels, and has been interpreted as a strengthening of the Saharan Heat Low (SHL) during wet monsoon years.�is study uses two atmospheric reanalysis datasets to examine interannual variability of Sahel rainfall and the shallow S...

In a previous paper (“Part 1”) it was shown that a combination of temperature-dependent viscosity and visco-plastic yielding is sufficient to give rudimentary plate tectonic-like behavior in three-dimensional models of mantle convection. Here, the calculations are extended to include two complexities which have been suggested as important in localizing deformation at plate boundaries: strain we...
