Nowadays, light weight and high strength metals are being used in various industries such as automotive and aerospace. Using aluminum-magnesium alloys is an efficient way to reduce the weight of a specific part. These alloys have poor formability in room temperature thus they should be formed at elevated temperature. Warm hydroforming and hot metal gas forming are conventional methods to form ...

We explored variation in patterns of percussive stone-tool use on coastal foods by Burmese long-tailed macaques (Macaca fascicularis aurea) from two islands in Laem Son National Park, Ranong, Thailand. We catalogued variation into three hammering classes and 17 action patterns, after examining 638 tool-use bouts across 90 individuals. Hammering class was based on the stone surface used for stri...

positions the subjects selected during the hammering task were located along the Dart Thrower's path from radial-extension to ulnarflexion. These positions were normalized to the neutral hammering position to calculate the average hammering path.

A method for discriminating a property of an object with the use of generated sound when striking it with a hammer is called a hammering test. This method, however, depends on human experience and skills. In addition, if we perform this test over a wide area of object, it is required to manually record hammering positions one by one. In order to solve these problems, this paper proposes a hamme...

Cooling during drilling Kirschner wires is not always effective in preventing thermal related damage. In this study, we used a human in vitro model and compared temperature elevation, insertion time, and extraction force between three Kirschner wire insertion methods-drilling with and without irrigation and pneumatic hammering. Forty five Kirschner wires were inserted into 15 fresh human cadave...

Complicated nano-patterns with linewidth less than 18 nm can be automatically hammered by using atomic force microscopy (AFM) tip in tapping mode with high speed. In this study, the special sample was thin poly(styrene-ethylene/butylenes-styrene) (SEBS) block copolymer film with hexagonal spherical microstructures. An ordinary silicon tip was used as a nano-hammer, and the entire hammering proc...

ly, the translation module in Sledgehammer and HOLyHammer can be seen as a two-step process: (1) Eliminate the higher-order features of the formulas to produce a rst-order problem. (2) Encode the type information in the target logic. In practice, the two steps are intertwined, because this gives rise to opportunities for optimizations. Translation of Higher-Order Features. The higher-order feat...
