Content-Defined Chunking (CDC) has been playing a key role in data deduplication systems in the past 15 years or so due to its high redundancy detection ability. However, existing CDC-based approaches introduce heavy CPU overhead because they declare the chunk cutpoints by computing and judging the rolling hashes of the data stream byte by byte. In this paper, we propose FastCDC, a Fast and eff...

Involute spur gears are key machine elements for power transmission in various industrial sectors. During transmission, the teeth subjected to high stresses. Many design modifications used reduce these stresses, such as increasing drive side pressure angle and profile shifting factor. These change contact ratio center distance of gear pair. Changing tooth thickness is another solution stress. B...

For 300 years, the models and metaphors of Newtonian physics have dominated the world of science. Newton offered an image of the universe as a machine, a clockwork mechanism. Newton's universe is ruled by linear cause and effect--one gear turns, which makes a second gear turn, which makes a third gear turn, and so on. This cause-effect relationship is captured in Newton's F=ma formula: force gi...

A vehicular driveline is the system used to transfer engine torque to the wheels. Resonances in the elastic parts of the driveline are important to handle when control of the engine and the transmission is optimized. Gear shifting by engine control is a new approach for automatic gear shifting with disengaging the clutch replaced by engine control. Resonances are excited in an uncontrolled driv...

This paper presents a numerical study of the effect transmission configuration on energy consumption an electric vehicle. The first part this is related to vehicle simulation model that takes into consideration resistances such as aerodynamic, rolling and inertial resistance well traction force. was then validated by means acceleration time, from 0 100 km/h in case single-speed gearbox. Vehicle...

The anatomical complexity of myomeres and myosepta has made it difficult to develop a comprehensive understanding of the relationship between muscle fiber architecture, connective tissue mechanics, and locomotor function of segmented axial musculature in fishes. The lateral hypaxial musculature (LHM) of salamanders is less anatomically complex and therefore a good system for exploring the basic...
