A fractal micro-electromechanical system and its pull-in stability
Journal of Low Frequency Noise, Vibration and Active Control, 2021 Pull-in instability occurs in a micro-electromechanical system, and it greatly hinders its normal operation. A fractal modification is suggested to make the system stable in all operation period. A fractal model is established using a fractal derivative,

Small-scale field evaluation of push-pull system against early- and outdoor-biting malaria mosquitoes in an area of high pyrethroid resistance in Tanzania [version 1; referees: 2 approved] [PDF]
Wellcome Open Research, 2017 Background: Despite high coverage of indoor interventions like insecticide-treated nets, mosquito-borne infections persist, partly because of outdoor-biting, early-biting and insecticide-resistant vectors. Push-pull systems, where mosquitoes are repelled

Fast identification of the pull-in voltage of a nano/micro-electromechanical system
Journal of Low Frequency Noise, Vibration and Active Control, 2022 The pull-in voltage is crucial in designing an optimal nano/micro-electromechanical system (N/MEMS). It is vital to have a simple formulation to calculate the pull-in voltage with relatively high accuracy.

Principles of cellular manufacturing/engineering/management: case studies and explications
International Journal of Production Management and Engineering, 2023 Process improvement through cellular manufacturing, engineering, and management (CEM) is largely dated and neglected. This article aims at rejuvenating the topic through re-conceptualization in the form of twelve principles of workcell design, operation,

Study on Design of Concrete Box Girder of A Railway Swivel Cable-Stayed Bridge [PDF]
E3S Web of Conferences, 2021 A swivel cable-stayed bridge over the existing railway is a span across the existing railway. The recommended scheme for the main bridge is (128 + 388 + 128) m steel mixed composite beam swivel diagonal pull bridge with span.

Push–pull farming systems [PDF]
Current Opinion in Biotechnology, 2014 Farming systems for pest control, based on the stimulo-deterrent diversionary strategy or push-pull system, have become an important target for sustainable intensification of food production. A prominent example is push-pull developed in sub-Saharan Africa using a combination of companion plants delivering semiochemicals, as plant secondary metabolites,

A Markov Chain Analysis of the Effectiveness of Kanban Card with Dynamic Information [PDF]
International Journal of Supply and Operations Management, 2017 The pull system produces products based on customer demands. Each station is isolated until a customer order is placed; then a signal or Kanban is sent from downstream station to upstream station and continues until the first station.
