Switch on, switch off: stiction in nanoelectromechanical switches [PDF]
Nanotechnology, 2013 We present a theoretical investigation of stiction in nanoscale electromechanical contact switches. We develop a mathematical model to describe the deflection of a cantilever beam in response to both electrostatic and van der Waals forces. Particular focus is given to the question of whether adhesive van der Waals forces cause the cantilever to remain ...

“Switched”: store‐switching behaviours [PDF]
International Journal of Retail & Distribution Management, 2008 PurposeThe purpose of this paper is to investigate store‐switching behaviours for main food‐shopping consequent on a change in operator for a major superstore; to relate results to previous research findings on store‐switching levels; and to use the results to emphasise new directions and dimensions for store‐switching research.Design/methodology ...

IET Radar, Sonar & Navigation, 2022 Recently, sparse linear arrays have aroused significant attention because they can provide increased degrees of freedom (DOFs) and enlarged inter‐element spacing, which are the critical factors to improve the accuracy of direction of arrival (DOA ...

eLife, 2021 Sleep slow waves are studied for their role in brain plasticity, homeostatic regulation, and their changes during aging. Here, we address the possibility that two types of slow waves co-exist in humans. Thirty young and 29 older adults underwent a night of polysomnographic recordings.

Algebraic distributed source localisation algorithm using TDOA and AOA measurements
The Journal of Engineering, 2019 This study proposes an algebraic distributed source localisation algorithm that combines time difference of arrival (TDOA) and angle of arrival (AOA) measurements. The proposed algorithm uses AOAs to remove the unknown parameters in TDOA equations caused

Target localisation from bistatic range measurements in multistatic passive radar using MDS
The Journal of Engineering, 2019 The target localisation in a multistatic passive radar system using bistatic range measurements from multiple transmitter–receiver pairs is considered. A novel closed-form solution employing multidimensional scaling (MDS) analysis technique is proposed ...

A DOA Estimation Method for Sparse Array Based on DFT Spectrum of Received Signals
IEEE Access, 2022 In the direction of arrival (DOA) estimation of sparse array received signals, the estimation accuracy of the grid search method in compressed sensing is improved with the increase of over-complete redundant dictionary elements.

Artificial noise-assisted physical layer security in D2D-enabled cellular networks
EURASIP Journal on Wireless Communications and Networking, 2017 Device-to-device (D2D) communication has been deemed as a promising technology in the next generation 5G wireless communication. Due to the openness nature of the transmission medium, secure transmission is also a critical issue in the D2D-enabled ...

Symmetric flipped nested array for mixed near‐field and far‐field non‐circular source localisation
IET Radar, Sonar & Navigation, 2022 As it is known, existing mixed near‐field and far‐field non‐circular source localisation rely on the uniform linear array (ULA). Compared with the ULA, the sparse array can obtain more consecutive lags and a larger physical array aperture.

Switching barrier scaling near bifurcation points for non-Gaussian noise [PDF]
, 2010 We study noise-induced switching of a system close to bifurcation parameter values where the number of stable states changes. For non-Gaussian noise, the switching exponent, which gives the logarithm of the switching rate, displays a non-power-law ...
