Dielectrophoresis Tutorial: Inspired by Hatfield's 1924 Patent and Boltzmann's Theory and Experiments of 1874

open access: yesELECTROPHORESIS, EarlyView.
ABSTRACT The first patent to describe dielectrophoresis (DEP) as a means and process to separate particles from a mixture was granted by the US Patent Office to Henry Stafford Hatfield in 1924. The novel methods of sample preparation and designs of electrode geometry covered by the patent's disclosures and claims describe the basis for most present‐day

Research and Experimental Verification of the Dynamic Pose Analysis Method of Advanced Hydraulic Support in a Fully Mechanized Mining Face

open access: yesEnergy Science &Engineering, EarlyView.
The advanced hydraulic support is modeled as a closed‐loop 10‐degree‐of‐freedom robotic arm. Based on the improved D–H parameter method, forward kinematic analysis is performed under left and right column driving conditions, and a follower model is constructed considering mechanical constraints.

Grid Integration of Single‐Phase Inverters Using a Robust PLL‐Less Control Strategy for Renewable Energy Applications

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT In this paper, a PLL‐less control technique for single‐phase grid‐connected voltage source converter (VSC) system is proposed that overcomes shortcomings in traditional PLL‐based and existing PLL‐less techniques. The proposed method avoids the use of a PLL and thus significantly decreases the computational complexity of the system as well as ...

Multiple Seasonal Autoregressive Integrated Moving Average Models

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT Many empirical time series show periodic patterns. SARIMA models and exponential smoothing methods are classical approaches to account for seasonal dynamics. However, they allow to model just one periodic component, while several time series have multiple seasonality, with periodic components possibly tangled among them.

Perspective Projection of an Ellipse and an Ellipsoid for Analytical View Factor Evaluation

open access: yesHeat Transfer, EarlyView.
ABSTRACT Radiative view factors are fundamental quantities for evaluating radiative heat transfer between different surfaces. While analytical expressions of view factors have been evaluated for various types of basic geometries, including circular disks and spheres, extending these solutions to more complex geometries, such as ellipses and ellipsoids ...
