For the characterization of vehicle acceleration, in addition to such common parameters as change of speed and acceleration in time, there should be applied one more parameter: change of acceleration increase in time. Change of acceleration increase in time jp progresses in four specific phases in each gear: I – beginning of run where jp is growing rapidly to the maximum value of the gear; II – jp reduction from the maximum value to the stabilized value; III – speeding up with stabilized value jp and IV – shifting when jp value is changing in a wide range to the maximum negative value and then to zero.
Introduction Preparation for performances such as jumping, acceleration, speed, agility, and others, should involve both long and short-term training programs. Long-term preparation may include a well-developed fitness training program, whereas short-term preparation should include a warm-up ( Amiri-Khorasani et al., 2010 ). One part of a warm-up includes stretching, which is often performed prior to physical exercises ( Amiri-Khorasani et al., 2010 , 2011 ). There are various stretching techniques, including static (SS), ballistic, proprioceptive neuromuscular

gear to perform a rocket-powered vertical landing. The capsule reenters and lands under a three-parachute canopy with the assistance of a retro-thrust system to reduce landing loads. The entire flight typically occurs autonomously, without flight or ground crew intervention. On January 11, 2016, the Space Acceleration Measurement System (SAMS) team was approached by NASA Headquarters (HQ) regarding flying an accelerometry unit on an upcoming flight on Blue Origin's New Shepard vehicle. Given the flight history of the Space Acceleration Measurement System as a
Design of an acceleration measurement system using a MEMS accelerometer to measure acceleration of automobiles in all the three axes is presented. Electronic stability control and anti-lock breaking systems in automobiles use the acceleration measurements to offer safety in driving. The system uses an ARM microcontroller to quantize the outputs of accelerometer and save the measurement data on a microSD card. A LabVIEW program has been developed to analyze the longitudinal acceleration measurement data and test the measurement system. Random noises generated and added with measurement data during measurement are filtered by a Kalman filter implemented in LabVIEW. Longitudinal velocity of the vehicle is computed from the measurement data and displayed on a graphical chart. Typical measurement of velocity of a vehicle at different accelerations and decelerations is presented.
The paper presents a standard vibrating table for fresh concrete testing adopted for determination of maximum dry density (ρdmax) of sand. Vibration is an efficient method for coarse soil compaction therefore vibrating tables are useful for ρdmax determination. Acceleration that the soil is subject to is one of the basic parameters of efficient compaction. A vibrating table with inertial excitation was supplemented by a frequency converter and subjected to dynamic tests. The results of measurements of dynamic parameters are included. The paper presents problems connected with this method and describes the relationship between efficiency of compaction and accelerations which the soil is subjected to.
