Deploying energy harvesting-based wireless sensor nodes (WSNs) in challenging environments often means we do not have precise control over the placement and orientation of nodes. This article introduces a novel smart WSN whose operation does depend on its orientation. The proposed unit is cube-shaped device, each side which complete module, sharing common storage communication bus with other fa...

Abstract The increasing share of variable renewable energy sources in power systems poses new challenges to policy makers and network planners alike because the sources’ variability insufficient storage capability. This requires development optimization models that consider inter-temporal connection between different periods aggregating them on a more general level (e.g., days or weeks). Howeve...

Global climate change is an alarming problem nowadays. Weather temperatures have been uncertain because of what many scientists claim the effect greenhouse gases, contributed mainly by energy industry. In Malaysia, industry provides a significant contribution to it economy making up about 20 percent GDP. Malaysia third largest natural gas exporter in Asia-Pacific region 2011 and eleventh world ...

A non-intrusive cleaning method for boiler tubes at Sasol Synfuels power station Secunda, in the Mpumalanga province of South Africa, is preferred over conventional methods that require shutdown. The elected utilizes sound energy waves, produced by an acoustic horn. Due to nature propagation and effectiveness required, there a requisite control operate sonic If horn’s frequency too low, it will...

liberalization of energy price increases costs of agricultural inputs and costs of agricultural production. all these changes may affect the overall competitiveness of domestic products with similar foreign products. as a result of that, total cost of agricultural products are increased and profitability are decreased. in this paper, energy consumption for producing corn were calculated using c...
