Ballistic movement performance in karate athletes

Medicine &amp Science in Sports &amp Exercise, 1997
Nine male karate athletes and 13 untrained men did maximal voluntary isometric (MVC) and ballistic elbow extension actions, the latter unloaded (L0) and against a load equal to 10% MVC (L10). The karate group achieved greater (P < 0.05) isometric (32%) and ballistic action peak torque with L0 (30%) and L10 (40%).

Reference ballistic imaging database performance

Forensic Science International, 2004
Ballistic imaging databases allow law enforcement to link recovered cartridge cases to other crime scenes and to firearms. The success of these databases has led many to propose that all firearms in circulation be entered into a reference ballistic image database (RBID).

Performance study of a ballistic compressor

AIAA Journal, 1976
An experimental and theoretical investigation of the performance of a ballistic compressor is described. Comparison of the computed ideal behavior of the ballistic compressor with experimental test pressures show that the ideal theory overestimates the generated pressure by as much as 30%.

The ballistic performance of narrow fabrics

International Journal of Impact Engineering, 2007
Woven fabrics are widely used in soft body armour. The ballistic performance of a range of narrow fabrics was determined and compared to that of wider fabric panels. In contrast to conventional ballistic fabrics, it was found that the performance of narrow fabrics was highly sensitive to changes in fabric specification.

Modeling and analysis of circuit performance of ballistic CNFET

Proceedings of the 43rd annual conference on Design automation - DAC '06, 2006
With the advent of carbon nanotube technology, evaluating circuit and system performance using these devices is becoming extremely important. In this paper, we propose a quasi-analytical device model for intrinsic ballistic CNFET, which can be used in any conventional circuit simulator like SPICE.

BALLISTIC PERFORMANCE OF ADHESIVELY BONDED JOINTS

Proceedings of the 32nd International Symposium on Ballistics, 2022
In this study, ballistic performance of adhesively-bonded Single Lap Joints is investigated experimentally and numerically. Using a specially-designed experimental set-up, a projectile with mass of 1.25 gr and density of 11.3 gr/cm3 was fired to the joints at a velocity of 288 m/s.

Ballistic impact performance of composite targets

Materials & Design, 2013
Ballistic impact performance of structures made of polymer matrix composites is presented. During the ballistic impact event, the energy lost by the projectile is absorbed by the composite target through various energy absorbing mechanisms. Compression of the target directly below the projectile, compression in the region surrounding the impacted zone,

The relationship between strength, power and ballistic performance

Journal of Electromyography and Kinesiology, 2009
The purpose of this investigation was to answer the question, "Does Stronger Mean Faster?". After a screening for elbow strength and speed, four groups of 8 subjects were selected for further investigation that fell into the extreme quartiles of the strength and speed continuums.
