The unmanned aerial vehicles (UAV) can be used in various fields such as weather applications, military applications, remote sensing, oceanography etc. There are many problems for UAV to find best and obstacle free path by detecting obstacle and calculate turn. In this paper, a novel method has proposed model for the obstacle free UAV routing by using the multi-factor distances. The proposed mo...
The vast majority of work to date concerned with obstacle avoidance for manipulators has dealt with task descriptions in the form ofpick-and-place movements. The added flexibility in motion control for manipulators possessing redundant degrees offreedom permits the consideration of obstacle avoidance in the context of a specified end-effector trajectory as the task description. Such a task defi...
The main characteristic feature of the pediatric mandible is that of decreased dimension, which leads to compromises in the open reduction and internal fixation (ORIF). In the dental segment, the cervically bulbous short stature primary teeth might act an obstacle during the maxillomandibular fixation conventionally. An increased osteogenic potential of bones favors rapid consolidation and remo...
abstract: one of the most visited & important spaces in different countries by tourist are urban areas. the old tehran which major part is located in district 12 is historical showcase of the capital, but, its hiidden cultural attraction is not used as it should be. this thesis occasionally engage in studying the efficacy of correct installation of travel guide boards in welfare & easily acc...
The infinite-dimensional mechanics of fluids and plasmas can be formulated as “noncanonical” Hamiltonian systems on a phase space of Eulerian variables. Singularities of the Poisson bracket operator produce singular Casimir elements that foliate the phase space, imposing topological constraints on the dynamics. Here we proffer a physical interpretation of Casimir elements as adiabatic invariant...
The relaxation dynamics of a polymer wound around a fixed obstacle constitutes a fundamental instance of polymer with twist and torque, and it is also of relevance for DNA denaturation dynamics. We investigate it by simulations and Langevin equation analysis. The latter predicts a relaxation time scaling as a power of the polymer length times a logarithmic correction related to the equilibrium ...
introduction. regarding the role of research in developing and improving a better culture, society and economics, 95% to 97% world finance in research belongs to developed countries while only 3%-5% to developing countries. although the universities as the major organizations are to do research works, it seems that there are some problems to bring this true. we tried to find out if a load of te...
The thrust bearing, as the only part bearing axial load, is extremely important in vertical hydroelectric generating units. Its working condition directly affects safe and reliable operation of unit. However, during operation, oil film easily damaged under influence complex factors. Installation deviation a key point that can cause temperature pressure changes film, affecting force on bearing. ...
We apply a holistic two-dimensional (2D) Tetris-like model, where particles move based on prescribed rules, to investigate the flow rate enhancement from hopper. This phenomenon was originally reported in literature as feature of placing an obstacle at optimal location near exit hopper discharging athermal granular under gravity. find that this is limited system sufficiently many particles. In ...
background: abnormal angulation of the lunate can be an indication of intercarpal pathology. on magnetic resonance images (mris) the lunate often looks dorsally angulated, even in healthy wrists. the tilt on individual slices can also be different and might be misinterpreted as pathological, contributing to inaccurate diagnoses and unnecessary surgery. the primary aim of this study was to deter...
