The existence of a kinematic morphology-density relation remains uncertain, and instead stellar mass appears the more dominant driver galaxy kinematics. We investigate dependence spin parameter proxy $\lambda_{R_e}$ on environment using marked cross-correlation method with data from SAMI Galaxy Survey. Our sample contains 710 galaxies spatially resolved velocity dispersion measurements. By util...

the management of road traffic accident and the care of casualties  has undergone many changes in recent years. to provide an uniform and systematic approach the ems, firefighters, red cross, red crescent and other rescuers must be updated to reduce entrapment times, and mortality rates, over better organisation and a methodical approach. the rescuers should not attempt to administer medical fi...

this article proposes composition of fuzzy sets theory with discrete-event simulation and puts it into application in order to model uncertain activity duration in simulating a real-world system. the purpose of this paper is to assess the usefulness of fuzzy simulation for modeling uncertain activity duration, especially when insufficient or no sample data is available. in this research, fuzzy ...

This technical memorandum describes a nonlinear guidance law for a single-missile single-target engagement. The guidance relies on the concepts of Lyapunov stability and backstepping, which are constructive methods in nonlinear control theory. The design of the guidance law allows taking into account the nonlinear relative kinematics between the missile and the target, and ensuring ultimate bou...

as a robot could be stable statically standing on three or more legs, a six legged walking robot can be highly flexible in movements and perform different missions without dealing with serious kinematic and dynamic problems. an experimental six legged walking robot with 18 degrees of freedom is studied and built in this paper. the kinematic and gait analysis formulations are demonstrated by an e...

Whether deformation of exhumed crust in a collisional orogen is driven by buoyancy or tectonic stress remains uncertain. The Sulu eastern China contains slowly subducted and high-pressure (HP)−ultrahigh-pressure (UHP) terranes, which provide good opportunity to understand whether the exhumation was buoyancy. We used field microscopic observations as well quartz c-axis fabrics determine kinemati...

A novel n(4-SPS+SP) serial-parallel manipulator (S-PM) formed by n 4-SPS+SP PMs with four degrees of freedom (DOF) connected in series is proposed in this paper. The kinematics , statics and stiffness modeJ of this seriaJ-PM is established.

Background: Lumbar motion analysis is used as a clinical method in the diagnosis and treatment of low back pain (LBP). So far, no studies have shown if manipulating the sacroiliac joint (SIJ) will change spinal kinematics.Objective: The main objectives of this study were to investigate the effects of SIJ manipulation on the lumbar kinematics in subjects with innominate rotation and to compare l...

This work renders the design of a robust state feedback optimal control strategy for an Autonomous Underwater Robotic Vehicle (AURV). The is developed using polytopic approach based on hydrodynamic parameter variation. Besides, backstepping designed to kinematics system. However, dynamics AURV system are controlled by technique. In this work, decoupled systems both horizontal and vertical used ...
