This article traces the strategic initiatives that Walmart undertook over the last decade to implement its ambitious vision of selling more sustainable products. This effort has been characterized by a gradual shift away from customer-facing initiatives aimed at labeling sustainable products toward supplier-facing initiatives targeted at improving environmental or social performance without rai...

Today, low-cost sensors in various civil engineering sectors are gaining the attention of researchers due to their reduced production cost and applicability multiple nodes. Low-cost also have advantage easily connecting microcontrollers such as Arduino. A low-cost, reliable acquisition system based on Arduino technology can further reduce price data monitoring, which make long-term monitoring p...

In this paper, one-cycle control (OCC), as a constant-frequency PWM control strategy for current control of a six-switch brushless dc (BLDC) motor drive is investigated. Developed current regulator is a unified controller and PWM modulator. Employing the one-cycle control strategy, decreases the torque ripple resulted from the conventional hysteresis current controllers and therefore, the vibra...
