During high growth era companies are making technical progress in automation and centralization of the plants, which needs large amount of manual work to maintain the automation systems. The strategy of maintaining the equipment of a plant is crucial for the effectiveness of manufacturing. Total productive maintenance (TPM) is a maintenance program, which involves concepts for maintaining plant...

The design of a double balanced CMOS downconversion mixer is presented with a novel calibration scheme for pulse injection flicker noise reduction. This self-biasing calibration technique enables the reduction of the mixers’ noise figure by over 20dB at baseband frequencies without any additional reference voltages, manual adjustment, or large inductors. This results in simpler IC testing and m...

Traditional uses of robotic technology in manufacturing have seen robotic work physically caged-off and separated from human workers. Automotive manufacturing is a success case for manufacturing automation. However, the human element is still an incredibly important facet of automotive manufacturing. Manual work still counts for 50% of the build process and requires two-thirds of the factory fo...

the main purpose of this study is measuring and comparing of peanut harvesting loss in manual and mechanical methods in addition to economic analysis of them. hence, a field was selected in astaneh-ashrafiyeh and divided to three different plots. two plots were applied to measure mechanical harvesting loss and third one was applied for manual harvesting loss. according to test results, the lowe...

recording nursing reports is considered as a quality assurance tool for patients and nurses. nowadays, the presence of electronic health record systems is an indicator of development. studies on advantages and disadvantages of the electronic and manual recording methods have shown different results. in this study, electronic and manual recording of nursing reports were compared from the perspec...
