When a Week Is Not A Week: How Temporal Boundaries Shift Regulatory Focus and Consumer Preference
Psychology &Marketing, EarlyView.ABSTRACT Does consumer perception of a sales event change if it falls across a calendar boundary (e.g., next month) versus within the current month, holding objective time constant? We investigate this question in the context of Cyber Monday, the global shopping event occurring the Monday after the U.S. Thanksgiving holiday.

An enhanced exponential reaching law based sliding mode control strategy for a three phase ups system [PDF]
Serbian Journal of Electrical Engineering, 2020 UPS is used to deliver a high quality sinusoidal waveform to consumers without any interruptions. This work proposes an Enhanced Exponential Reaching Law (EERL) based Sliding Mode Control (SMC) for a three- phase UPS 30 kVA system used in ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This work addresses the challenge of bidirectional trajectory tracking in solar‐powered wheeled mobile robots (WMRs), considering the mechanical structure, actuator‐driver, and power stage subsystems. Notably, this is the first study to explicitly model and control the actuator‐driver subsystem within this context. The proposed solution relies

Adaptive Sliding‐Mode Control of a Perturbed Diffusion Process With Pointwise In‐Domain Actuation
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT A sliding mode–based adaptive control law is proposed for a class of diffusion processes featuring a spatially‐varying uncertain diffusivity and equipped with several point‐wise actuators located at the two boundaries of the spatial domain as well as in its interior.

Sensorless Control of Permanent Magnet Synchronous Motor Based on the Improved Sliding Mode Observer [PDF]
Xibei Gongye Daxue Xuebao, 2018 Sliding mode observer (SMO) which has a strong robustness is used in the sensorless control system of permanent magnet synchronous motor (PMSM). The method is usually used to estimate the rotor position although it has the chattering problem.
