Using the amplitude-modulation pulse (AMP) representation of continuousphase modulation (CPM) introduced more than a decade ago by Laurent, the power spectral density (PSD) of minimum-shift-keying (MSK)-type modulations (modulation index equal to one-half) is computed in the presence of data imbalance. The advantage of this technique is that closed-form expressions can be obtained that clearly ...

This paper presents a reduce roll vibration of the full vehicle model with passive suspension systems using vibration absorber to change the dynamic system matrix stat’s eigenvalue. Since using the controller system has been splurged and required to energy consuming, in this research the vehicle body roll vibration has been reduced and supplied vehicle stability using a vibration absorber for t...

Maneuvering flight has long been recognized as an important component of the natural behavior of many bird species, but has been the subject of little experimental work. Here we examine the kinematics and neuromuscular control of turning flight in the rose-breasted cockatoo Eolophus roseicapillus (N=6), testing predictions of maneuvering flight and control based on aerodynamic theory and prior ...

Using a principal component (PC) basis that accommodates order unity features in the slow roll parameters as fine as 1/10 of a decade across more than 2 decades of the inflationary expansion, we test slow roll and single field inflation with the WMAP7 data. Detection of any non-zero component would represent a violation of ordinary slow roll and indicate a feature in the inflaton potential or s...

Some important walking functions are adversely affected or eliminated in prosthesis users because of reduced or absent ankle motion. This retrospective data analysis determined the effect of prosthetic ankle units on the characteristics of the ankle-foot roll-over shape in persons with bilateral transtibial amputations. Seventeen subjects were fitted with Endolite Multiflex Ankles to provide an...

To investigate the effect of head roll tilt on the binocular coordination of ocular counterroll in non-human primates, we measured binocular ocular counterroll in two rhesus monkeys fixating a straight ahead target, while adopting different head roll tilt positions. We used two infrared cameras to take snapshots of the left and the right eye in order to measure the resulting ocular counterroll ...

Illusory perceptions of motion and orientation arise during human centrifuge runs without vision. Asymmetries have been found between acceleration and deceleration, and between forward-facing and backward-facing runs. Perceived roll tilt has been studied extensively during upright fixed-carriage centrifuge runs, and other components have been studied to a lesser extent. Certain, but not all, pe...

Purpose – Legged vehicles offer several advantages over wheeled vehicles, particularly on broken terrain, but are presently too slow to be considered for many high-speed tasks. This paper presents an effective 3D controller for a high-speed quadruped trot. Design/methodology/approach – To successfully regulate forward velocity and heading, secondary motions such as body pitch and roll must be s...

We present a real-time method for stabilizing video sequences taken from an oscillating camera. We estimate camera rotation (roll) and translation on the image plane with Fourier spectrum analysis and Integral projection matching and then filter-out high-frequency motion components (presumably due to unintentional oscillation) , preserving intentional motion.
